+# MagiC Governance
+
+This document describes how the MagiC open-source project is governed — how decisions are made, how roles are assigned, and how the community evolves the project over time.
+
+MagiC is licensed under [Apache 2.0](LICENSE) and welcomes contributions from anyone. Governance is intentionally lightweight for now and will formalize as the project grows.
+
+## Mission
+
+**Make it easy to run fleets of AI workers at any scale — open, transport-agnostic, and vendor-neutral.**
+
+MagiC is infrastructure. It does not build AI agents; it manages them. Our north star is to be to AI agents what Kubernetes is to containers: boring, dependable, composable.
+
+Guiding principles:
+
+- **Open by default** — the protocol (MCP²) and core are Apache 2.0. No feature is gated behind a commercial tier in the open-source distribution.
+- **Vendor-neutral** — we do not favor any LLM, vector DB, or worker framework. Adapters are pluggable.
+- **Operational realism** — every feature must be operable in production: observable, testable, upgradeable, backup-able.
+- **Small, sharp primitives** — prefer a clean protocol + small core over a monolith with many opinions.
+
+## Roles
+
+| Role | Description | How to become one |
+|------|-------------|-------------------|
+| **User** | Runs MagiC, reports bugs, asks questions in Discussions. | Just use the project. |
+| **Contributor** | Submits pull requests, issues, or documentation. | Open a PR. |
+| **Committer** | Has write access to a specific module or area. Reviews PRs in that area. | Sustained contributions + nomination by a Maintainer. |
+| **Maintainer** | Has merge rights across the repo. Shapes roadmap. Enforces CoC. | See "Becoming a Maintainer" below. |
+| **Steering / BDFL** | Final call on contested decisions. Currently the project lead. | Will transition to a Steering Committee once the project has 3+ active Maintainers. |
+
+Committer-level access is granted per directory via [`.github/CODEOWNERS`](.github/CODEOWNERS). Maintainers are listed in [`MAINTAINERS.md`](MAINTAINERS.md).
+
+## Decision Making
+
+We use **lazy consensus** for most decisions:
+
+1. A change is proposed (PR, issue, RFC).
+2. If no one objects within a reasonable review window (typically 72 hours for non-trivial changes, 24 hours for trivial ones), the change is assumed accepted.
+3. A single approving review from a relevant Maintainer is sufficient to merge.
+
+For changes that are **non-trivial, controversial, or breaking**, we require:
+
+- An issue or design doc under `docs/superpowers/specs/` describing the motivation, alternatives, and migration path.
+- At least **two** approving reviews from different Maintainers.
+- A **7-day comment window** before merge, explicitly announced in the PR body.
+
+If lazy consensus breaks down (someone objects and agreement cannot be reached), the decision escalates in this order:
+
+1. The PR author and reviewers attempt to resolve in the PR conversation.
+2. If unresolved, the Maintainers discuss in a tracking issue or async thread.
+3. If still unresolved, the project lead (BDFL) makes the final call. The decision is documented in the issue and linked from the CHANGELOG.
+
+## Release Cadence
+
+We follow [Semantic Versioning](https://semver.org/).
+
+| Type | Cadence | Contents |
+|------|---------|----------|
+| **Minor** (`0.x.0`, `x.Y.0`) | Roughly every 6 weeks | New features, additive API changes, non-breaking protocol evolution. |
+| **Patch** (`x.y.Z`) | On demand | Bug fixes, security patches, documentation fixes. Same-day for critical security fixes. |
+| **Major** (`X.0.0`) | When necessary | Breaking changes. Requires a deprecation cycle (see [Upgrade Guide](docs/ops/upgrade-path.md)). |
+
+Before 1.0.0, we may introduce breaking changes in minor releases, but we commit to documenting them in [`CHANGELOG.md`](CHANGELOG.md) with clear migration notes.
+
+Each release:
+
+1. A release PR updates `CHANGELOG.md` with the version number and date.
+2. CI passes on `main`.
+3. A Maintainer tags the release (`v0.x.y`) and GitHub Actions publishes the Go binary, Docker image, and SDK packages.
+4. The release is announced in GitHub Discussions.
+
+## Becoming a Maintainer
+
+MagiC maintainership is earned through sustained contribution, technical depth, and alignment with the project's mission.
+
+Criteria (non-exhaustive):
+
+- **Sustained contributions** over 3+ months: merged PRs, reviews, triage, documentation, support in Discussions.
+- **Technical depth** in at least one area (core, SDK, docs, infrastructure) and working knowledge of the overall architecture.
+- **Community participation**: helpful tone, enforcing the Code of Conduct, mentoring newer contributors.
+- **Alignment** with the mission and principles above.
+
+Nomination process:
+
+1. An existing Maintainer opens a private discussion with the other Maintainers proposing the nominee.
+2. Maintainers have 7 days to raise objections.
+3. If there are no blocking objections, the nominee is offered maintainership.
+4. If accepted, they are added to [`MAINTAINERS.md`](MAINTAINERS.md) and to the `@maintainers` GitHub team.
+
+There is no fixed ratio of PRs or lines of code. Judgment is holistic.
+
+## Removing a Maintainer
+
+Maintainers may step down at any time by opening a PR that moves their entry to the "Emeritus" section of `MAINTAINERS.md`.
+
+Involuntary removal is reserved for:
+
+- Serious or repeated Code of Conduct violations.
+- Extended inactivity (12+ months with no contributions or review) without a sabbatical notice.
+- Actions that materially harm the project or its users.
+
+Removal requires agreement from a majority of remaining Maintainers (excluding the subject of removal). The reasoning is documented in a private discussion and, where appropriate, summarized publicly.
+
+## Conflict Resolution
+
+1. **Code of Conduct issues** → report to security@magic-ai-sdk.dev or any Maintainer. See [`CODE_OF_CONDUCT.md`](CODE_OF_CONDUCT.md). CoC issues are handled confidentially.
+2. **Technical disagreements** → try to resolve in the PR or issue thread first. Escalate to Maintainers if stuck. Last resort is the project lead.
+3. **Governance disputes** → raise in a GitHub Discussion under the "Governance" category. Maintainers will respond within 14 days.
+
+The [Code of Conduct](CODE_OF_CONDUCT.md) (Contributor Covenant v2.1) applies in all project spaces — GitHub, Discord (when launched), mailing lists, events, and private channels related to the project.
+
+## Security
+
+Security vulnerabilities are handled through a separate channel to protect users before a fix is public. See [`SECURITY.md`](SECURITY.md).
+
+Summary: email **security@magic-ai-sdk.dev** or open a private security advisory on GitHub. Do **not** open public issues for security bugs.
+
+## Trademarks
+
+"MagiC" and the MagiC logo are currently held by the project lead (Kien) on behalf of the project. Usage is permitted for:
+
+- Referring to the MagiC project in documentation, articles, and talks.
+- Showing the logo alongside "Works with MagiC" or similar factual statements.
+
+Usage is **not** permitted for:
+
+- Naming a competing product or service that could be confused with MagiC.
+- Implying official endorsement without written permission.
+
+A formal trademark policy will be published if the project transfers to a foundation.
+
+## Changes to This Document
+
+Changes to `GOVERNANCE.md` require a PR with a 14-day comment window and approval from at least two Maintainers (or the project lead during the single-Maintainer period).
+
+## Acknowledgements
+
+This governance model draws from the practices of [Kubernetes](https://github.com/kubernetes/community/blob/master/governance.md), [Envoy](https://github.com/envoyproxy/envoy/blob/main/GOVERNANCE.md), and [OpenTelemetry](https://github.com/open-telemetry/community/blob/main/community-membership.md). We thank those communities for documenting their patterns publicly.

+## Supply Chain Verification
+
+All release binaries and container images are signed with Sigstore cosign
+(keyless OIDC) and carry SLSA Level 3 build provenance. For exact
+verification commands (cosign `verify-blob`, `verify`, `slsa-verifier
+verify-artifact`, `verify-image`), see
+[`docs/security/signing-and-provenance.md`](docs/security/signing-and-provenance.md).
+
+Hardening summary:
+
+- All GitHub Actions are pinned to immutable commit SHAs (no floating tags).
+- Release binaries: `.cosign.bundle` published alongside each asset.
+- Container images (`ghcr.io/kienbui1995/magic`): signed; signatures in the
+  public Rekor transparency log.
+- SLSA v1.0 Level 3 provenance attestations are published with every release
+  via `slsa-framework/slsa-github-generator`.
+- Container images are scanned with Trivy (CRITICAL/HIGH) before publish.
+- CodeQL + gosec SAST + govulncheck run on every PR and push to `main`.
+- OpenSSF Scorecard runs weekly and on `main` pushes.

+# Getting Support
+
+MagiC is an open-source project maintained on a best-effort basis. This page describes where to go for each type of question.
+
+## Quick Guide
+
+| I want to... | Channel |
+|--------------|---------|
+| Report a bug | [GitHub Issues](https://github.com/kienbui1995/magic/issues/new?template=bug_report.yml) |
+| Request a feature | [GitHub Issues](https://github.com/kienbui1995/magic/issues/new?template=feature_request.yml) |
+| Ask a how-to or design question | [GitHub Discussions](https://github.com/kienbui1995/magic/discussions) |
+| Share something I built | [GitHub Discussions → Show and Tell](https://github.com/kienbui1995/magic/discussions) |
+| Report a security vulnerability | **Do not open a public issue.** See [`SECURITY.md`](SECURITY.md). |
+| Report a Code of Conduct concern | See [`CODE_OF_CONDUCT.md`](CODE_OF_CONDUCT.md). |
+| Get commercial support | See "Enterprise Support" below. |
+
+## Before You Open an Issue
+
+Please check, in this order:
+
+1. **Existing issues** — your question may already be answered: <https://github.com/kienbui1995/magic/issues?q=is%3Aissue>
+2. **Documentation** — the [README](README.md), [CLAUDE.md](CLAUDE.md), `docs/`, and the docs site cover common setup and API questions.
+3. **CHANGELOG** — check [`CHANGELOG.md`](CHANGELOG.md) to see whether the behaviour you see is expected for your version.
+4. **Source code** — the Go core is under `core/` and is reasonably small; grep is fast.
+
+If you still need help, open an issue or discussion with:
+
+- Version of MagiC (`magic version` if available, otherwise git commit / Docker tag).
+- Go and Python versions, if relevant.
+- OS and deployment method (binary, Docker, Helm, Railway, etc.).
+- Minimal reproduction — smallest config and command sequence that shows the problem.
+- Relevant logs (redact any secrets).
+
+## Response Times (Best-Effort)
+
+MagiC has no paid support SLA by default. The table below is a **best-effort** target during the single-maintainer period.
+
+| Channel | Target first response |
+|---------|-----------------------|
+| Security advisories | 48 hours (committed — see [`SECURITY.md`](SECURITY.md)) |
+| Bug reports | 3 business days |
+| Feature requests | 1 week |
+| Discussions | 1 week |
+
+We may be slower during holidays, weekends, or major releases. If something is truly urgent, say so in the title and we will prioritize as able.
+
+## Channels
+
+### GitHub Issues
+
+Use for concrete, reproducible bugs and for feature requests with a clear use case. Issue templates will guide you.
+
+### GitHub Discussions
+
+Use for anything that is not a defect in the code:
+
+- "How do I do X with MagiC?"
+- "Is this the right design for my use case?"
+- "I built a worker for Y, check it out."
+- "What is the roadmap for Z?"
+
+### Security
+
+Email **security@magic-ai-sdk.dev** or open a [GitHub Security Advisory](https://github.com/kienbui1995/magic/security/advisories/new). See [`SECURITY.md`](SECURITY.md) for scope and disclosure timeline.
+
+### Chat (Planned)
+
+A public chat (Discord or similar) is on the roadmap but not yet launched. When it ships, this page will be updated with an invite link. Until then, please use Discussions — it keeps answers searchable.
+
+### Social Updates
+
+Release announcements and project updates are posted under the GitHub Releases feed and [Discussions → Announcements](https://github.com/kienbui1995/magic/discussions).
+
+## Enterprise Support
+
+Commercial support, SLAs, private audits, and architectural engagements are available on request. Typical scope:
+
+- Defined response-time SLA (business-day or 24/7).
+- Named engineer(s) for incident response.
+- Private security audits and patch backports.
+- Architecture review and deployment assistance (on-prem, air-gapped, multi-region).
+- Custom development (new adapters, connectors, integrations).
+
+To enquire, email the project lead at the address listed in [`MAINTAINERS.md`](MAINTAINERS.md), or contact: **TODO — enterprise@magic-ai-sdk.dev (placeholder, confirm before publishing).**
+
+This offering is separate from the open-source project. The Apache 2.0 license applies regardless of whether you have a commercial agreement.
+
+## Contributing
+
+If you want to help others get support, answering questions in Discussions is one of the most valuable contributions possible. See [`CONTRIBUTING.md`](CONTRIBUTING.md).

+  title: MagiC Protocol (MCP²) API
+  version: 1.0.0
+  description: |
+    **MagiC** (capital C = Company / Crew / Claw) is an open-source framework for
+    managing fleets of AI workers. Think *"Kubernetes for AI agents"* — it doesn't
+    build agents, it manages any agents built with any tool (CrewAI, LangChain,
+    custom bots, etc.) through an open protocol.
+
+    This document describes the HTTP surface of the MagiC Gateway, implementing
+    MagiC Protocol (MCP²) version **1.0**. All responses include the
+    `X-API-Version` header carrying the server's protocol version. Clients may
+    send the same header to assert a target version — a mismatched MAJOR is
+    rejected; a mismatched MINOR is served with a `Warning` header.

+## Scope
+
+The suite targets the dimensions that matter for enterprise comparison against
+Temporal / Dapr Workflows / Ray Serve:
+
+| Dimension | What we measure | Where |
+|-----------|-----------------|-------|
+| **Throughput** | Tasks completed per second, 1/10/100 workers | `scenarios/throughput.md` |
+| **Latency** | p50/p95/p99 dispatch latency under sustained load | `scenarios/latency.md` |
+| **Fan-out** | Parallel vs sequential workflow step execution | `scenarios/fanout.md` |
+| **Durability** | DLQ recovery + retry success under induced failures | `scenarios/durability.md` |
+| **Cost accuracy** | Cost accounting correctness under load | `scenarios/cost-tracking.md` |
+| **Scalability** | Route time at 1 → 1000 registered workers | `core/benchmarks/routing_test.go` |
+
+## Hardware Recipe (reproducibility)
+
+Results published in `results/` must be produced on — or clearly labelled
+deviations from — this baseline rig:
+
+- CPU: 4 physical cores, x86_64
+- RAM: 8 GB
+- Disk: local NVMe SSD
+- OS: Linux kernel 6.x, cgroups v2
+- Go: **1.25**
+- Postgres: **16** (with `pgvector`), local socket
+- Network: loopback only (no cross-host NIC)
+- MagiC version: tagged release (see file name `results/vX.Y.Z-*.md`)
+
+Run each scenario **three times** and publish the median. Note any deviation
+(CPU model, cloud instance) in the result header.
+
+## Output Format
+
+Load-test scenarios emit two artefacts:
+
+1. **CSV** — one row per task: `timestamp,task_id,submit_ms,complete_ms,status`
+2. **Markdown summary** — aggregates in `results/vX.Y.Z-<scenario>.md`
+   including methodology, p50/p95/p99, throughput, success rate, observations.
+
+## Versioning
+
+Benchmarks are pinned to the MagiC release they ran against. File naming:
+
+```
+results/v0.8.0-baseline.md
+results/v0.9.0-baseline.md
+```
+
+Never overwrite historic results; append new runs as new files so regressions
+are visible over time.

+# Scenario: Cost tracking accuracy
+
+Verify that MagiC's `costctrl` module records the correct aggregate cost under
+concurrent load — not just at steady state, but with concurrent submitters
+racing against the same org budget.
+
+## Goal
+
+After 10 000 tasks of known cost, the reported org spend must match the
+analytical ground truth to within floating-point epsilon.
+
+```
+|reported_spend − sum(task.cost)| / sum(task.cost)  <  1e-6
+```
+
+## Setup
+
+Echo worker reports a deterministic cost (`$0.001` per call) via the
+`complete` message payload. Run **5 concurrent load generators** so cost
+writes are interleaved.
+
+```bash
+# 5 terminals, each:
+python3 ../scripts/load.py --rate 50 --total 2000 --out costN.csv
+```
+
+Org starts with a soft budget of `$100`; each run pushes `$2` of spend so
+total is `$10`, well within the limit. A second run intentionally exceeds the
+limit to verify `budget.exceeded` fires exactly once.
+
+## Procedure
+
+1. Reset org spend: `POST /api/v1/orgs/{id}/spend/reset` (dev-only endpoint).
+2. Run 5 concurrent load runs.
+3. Query spend: `GET /api/v1/orgs/{id}/spend`.
+4. Compare against `5 × 2000 × 0.001 = $10.000`.
+5. Repeat with budget $5 and confirm `budget.exceeded` fires at/after $5.
+
+## Metrics
+
+| Metric | Definition |
+|--------|------------|
+| `cost_delta_pct` | `|reported − expected| / expected` (must be < 1e-6) |
+| `budget_event_count` | number of `budget.exceeded` events (must be 1 in the overspend run) |
+| `cost_write_p99_ms` | latency of the `cost.recorded` handler observed via event bus |
+
+## Expected Shape (not a promise)
+
+`cost_delta_pct` should be effectively zero — this is a correctness check
+disguised as a benchmark. If drift appears, suspect non-atomic update in the
+`costctrl` store path.

+# Scenario: Durability — DLQ and retry success rate
+
+Inject worker failures and verify that MagiC retries, eventually succeeds, or
+routes to the Dead Letter Queue with no silent task loss.
+
+## Goal
+
+Under a 10% worker failure rate, measure:
+
+- `retry_success_rate` — fraction of failed attempts that later succeed
+- `dlq_rate` — fraction of tasks that land in DLQ (exhausted retries)
+- `lost_rate` — fraction with no terminal event (**must be 0**)
+
+## Setup
+
+Worker is started with fault injection:
+
+```bash
+python3 ../scripts/worker.py --port 9100 --fail-rate 0.1
+```
+
+At each dispatch, the worker rolls a dice and returns HTTP 500 with probability
+`fail-rate`. MagiC's dispatcher retries up to `maxRetries=2`, then moves to DLQ.
+
+## Procedure
+
+Submit 5 000 tasks at 50 rps. Let the run drain for 30 s after the last submit
+so retries can complete.
+
+```bash
+python3 ../scripts/load.py \
+    --rate 50 --total 5000 \
+    --drain 30 \
+    --out ../results/durability.csv
+```
+
+After the run, query DLQ:
+
+```bash
+curl -s http://localhost:8080/api/v1/dlq | jq '.tasks | length'
+```
+
+## Metrics
+
+| Metric | Definition |
+|--------|------------|
+| `retry_success_rate` | (tasks with ≥1 attempt_failed + final ok) / tasks with ≥1 attempt_failed |
+| `dlq_rate` | DLQ size / 5000 |
+| `lost_rate` | 1 − (ok + dlq) / 5000 — **MUST be 0** |
+
+## Expected Shape (not a promise)
+
+With 10% per-attempt failure and 3 total attempts, DLQ rate should be around
+0.1³ = 0.001 (0.1%). Anything higher than 0.5% suggests retry logic regression.
+`lost_rate` above zero is a correctness bug, not a performance regression.

+# Scenario: Workflow fan-out (parallel vs sequential)
+
+Compare wall-clock time for a 100-step workflow executed (a) sequentially vs
+(b) fully parallel. This is the flagship comparison against Temporal activity
+fan-out and Dapr workflow children.
+
+## Goal
+
+Two numbers per MagiC release:
+
+- `workflow_seq_100_ms` — 100 echo steps with `depends_on` chained linearly.
+- `workflow_par_100_ms` — 100 echo steps with no dependencies.
+
+## Setup
+
+Bench stack with **20 workers** (parallel case needs enough workers so scheduler
+is not the bottleneck). Each echo step adds 10 ms artificial latency inside the
+worker so dispatch overhead is visible without being drowned by sleep.
+
+## Procedure
+
+Submit workflow JSON via `POST /api/v1/workflows`. Two fixtures live in this
+directory:
+
+- `fanout-seq-100.json` — 100 steps, each `depends_on: [previous]`
+- `fanout-par-100.json` — 100 steps, all independent
+
+```bash
+curl -X POST http://localhost:8080/api/v1/workflows \
+    -H 'Authorization: Bearer $TOKEN' \
+    -d @fanout-par-100.json
+```
+
+Wait for `workflow.completed` via SSE and record the total elapsed.
+
+## Metrics
+
+| Metric | Definition |
+|--------|------------|
+| `workflow_seq_100_ms` | wall-clock: submit → workflow.completed (sequential) |
+| `workflow_par_100_ms` | wall-clock: submit → workflow.completed (parallel) |
+| `parallel_efficiency` | `seq_ms / (par_ms * 100)` — 1.0 means perfect scaling |
+
+## Expected Shape (not a promise)
+
+Sequential should be ~ (100 × per-step overhead + 100 × 10 ms sleep).
+Parallel should approach (1 × per-step overhead + 1 × 10 ms sleep) plus
+dispatch fan-out cost. If `parallel_efficiency` < 0.8, investigate router
+contention or DB write amplification.

+# Scenario: Latency under sustained load
+
+Characterise dispatch latency distribution when MagiC is operating steadily
+below its throughput ceiling.
+
+## Goal
+
+Produce p50 / p95 / p99 / p99.9 for submit→complete latency at a **fixed**
+rate of 100 requests per second, held for 10 minutes.
+
+## Setup
+
+Same bench stack as `throughput.md`, with **10 workers** (enough headroom that
+queue depth stays near zero).
+
+## Procedure
+
+```bash
+python3 ../scripts/load.py \
+    --rate 100 \
+    --duration 600 \
+    --concurrency 50 \
+    --out ../results/latency-100rps.csv
+```
+
+The load generator enforces the rate with a token bucket, so spikes do not
+artificially inflate the tail.
+
+## Metrics
+
+| Metric | Definition |
+|--------|------------|
+| `latency_p50_ms` | median submit→complete |
+| `latency_p95_ms` | 95th percentile |
+| `latency_p99_ms` | 99th percentile |
+| `latency_p999_ms` | 99.9th percentile |
+| `error_rate` | fail / total |
+
+## Anti-patterns to guard against
+
+- **Coordinated omission**: the load generator records request start time at
+  scheduled tick, not at actual submit, so slow responses do not hide missing
+  latency samples.
+- **Warm-up**: the first 30 seconds are excluded from the aggregate; they
+  cover connection pool warm-up and JIT-style amortised cache fills.
+
+## Expected Shape (not a promise)
+
+At 100 rps with 10 workers the p99 should sit inside a small number of tens of
+milliseconds; p99.9 can spike with Go GC pauses. Record the GC pause histogram
+if possible (`GODEBUG=gctrace=1`).

+# Scenario: Throughput
+
+Measure the maximum sustained rate at which MagiC can route and dispatch tasks
+end-to-end through the gateway.
+
+## Goal
+
+Produce `tasks_completed_per_second` for 1, 10, and 100 concurrent echo workers
+on the reference rig (see `../README.md`).
+
+## Setup
+
+1. Start the bench stack:
+   ```bash
+   docker compose -f ../scripts/docker-compose.bench.yml up -d
+   ```
+2. Start N echo workers (one per terminal, or with `--replicas N` via docker
+   compose):
+   ```bash
+   python3 ../scripts/worker.py --port 9100
+   ```
+3. Register each worker against the gateway (the worker script auto-registers
+   on boot).
+
+## Procedure
+
+Submit **10 000** tasks as fast as the client can push. The load generator uses
+`asyncio` with bounded concurrency (50 inflight by default):
+
+```bash
+python3 ../scripts/load.py \
+    --rate 0 \
+    --total 10000 \
+    --concurrency 200 \
+    --out ../results/throughput-N<workers>.csv
+```
+
+`--rate 0` means "no rate limit, push as fast as possible". The throughput
+ceiling is observed by watching completed tasks/sec once the submit phase
+stabilises.
+
+## Metrics
+
+| Metric | Definition |
+|--------|------------|
+| `throughput_tasks_per_sec` | tasks with `status=ok` divided by wall clock elapsed |
+| `submit_p99_ms` | 99th percentile submit→ack latency |
+| `complete_p99_ms` | 99th percentile submit→complete latency |
+| `success_rate` | ok / total |
+
+## Expected Shape (not a promise)
+
+- 1 worker: bounded by worker concurrency, flat-lines around worker limit.
+- 10 workers: near-linear scale until gateway becomes CPU-bound.
+- 100 workers: router `best_match` scoring dominates; scale factor < linear.
+
+Record the knee of the curve in the result summary.

+"""Echo worker for MagiC benchmarks.
+
+Implements the minimal MagiC worker contract:
+- On boot: registers with the gateway advertising an `echo` capability.
+- On dispatch (POST /dispatch): sleeps `--latency-ms`, optionally fails with
+  probability `--fail-rate`, otherwise returns `{type: "complete", ...}`.
+
+This worker is intentionally dependency-light: stdlib + httpx + a small
+asyncio HTTP server via `aiohttp` if available, else falls back to
+`http.server` in a thread.
+
+Example:
+    python3 worker.py --port 9100
+    python3 worker.py --port 9101 --fail-rate 0.1 --latency-ms 50

+# E2E Tests
+
+End-to-end tests exercising the full MagiC stack in-process:
+
+- **Gateway** (HTTP handler with middleware + rate limiting)
+- **Registry**, **Router**, **Dispatcher**, **Orchestrator**
+- **Store** (MemoryStore — no Postgres required)
+- **Event bus**, **CostCtrl**, **Evaluator**, **Monitor** + Prometheus metrics
+- **Webhook manager** with HMAC-signed delivery
+- Workers implemented as `httptest.NewServer` handlers
+
+Gated by the `e2e` build tag so unit-test runs (`go test ./...`) are not affected.
+
+## Run
+
+```bash
+cd core
+go test -tags=e2e -race -count=1 -timeout=180s ./internal/e2e/...
+```
+
+Verbose output:
+
+```bash
+go test -tags=e2e -v ./internal/e2e/...
+```
+
+## Scenarios
+
+| Test | What it catches |
+|------|-----------------|
+| `TestE2E_TaskLifecycle` | register → submit → complete; cost recorded; task.completed event; `magic_tasks_total` incremented |
+| `TestE2E_WebhookDelivery` | task.completed triggers HMAC-signed POST to receiver (verifies X-MagiC-Event + X-MagiC-Signature + envelope) |
+| `TestE2E_TaskCancel` | pending task → cancel → status cancelled + task.cancelled event; no task.completed raced in |
+| `TestE2E_WorkerPauseResume` | paused worker skipped by router (503); resume restores routing |
+| `TestE2E_WorkflowDAG` | 2-step workflow with `depends_on` runs sequentially |
+| `TestE2E_RateLimit` | 60 parallel task submissions trigger at least one 429 at the per-IP burst of 20 |
+| `TestE2E_AuditLog` | audit query endpoint returns filtered + paginated entries with expected JSON shape |
+
+## Timing
+
+- Runtime: < 30s total on a warm machine.
+- `TestE2E_WebhookDelivery` dominates because the retry sender ticks on a 5s interval — up to ~15s wallclock there.
+
+## Scope / non-scope
+
+**In scope**: catching regressions across module boundaries (gateway ↔ dispatcher ↔ store ↔ bus ↔ webhook sender).
+
+## Postgres-backed E2E
+
+`postgres_test.go` (same build tag) covers migrations / RLS / pool under a
+real Postgres via testcontainers-go. See `docs/testing/e2e-postgres.md` for
+run instructions and fail modes. Tests auto-skip when Docker is unavailable.
+
+**Out of scope** (future work):
+- OIDC / JWT auth path — needs a fake issuer.
+- OTel exporter verification — needs an in-process collector.

+# Deploying MagiC on Kubernetes
+
+Three supported install paths, in order of preference:
+
+| Path | When to use |
+|------|-------------|
+| **Helm chart** (`deploy/helm/magic/`) | Production. Templated, supports PDB / HPA / ServiceMonitor / optional Postgres subchart. |
+| **Plain manifests** (`deploy/k8s/`) | Air-gapped clusters, GitOps without Helm (ArgoCD kustomize), quick evaluation. |
+| **Docker Compose** (repo root `docker-compose.yml`) | Single-host dev / demo. See `docs-site/guide/deployment.md`. |
+
+---
+
+## Option 1 — Helm (recommended)
+
+### Prerequisites
+
+- Kubernetes ≥ 1.24
+- Helm ≥ 3.11
+- (Optional) cert-manager + an ingress controller for TLS
+- (Optional) Prometheus Operator if enabling `metrics.serviceMonitor`
+
+### Install
+
+```bash
+# 1. Add the Bitnami repo for the Postgres dependency
+helm dependency update deploy/helm/magic/
+
+# 2. Generate an admin API key (32+ chars)
+export MAGIC_API_KEY=$(openssl rand -hex 32)
+
+# 3. Install with the bundled Postgres
+helm install magic deploy/helm/magic/ \
+  --namespace magic --create-namespace \
+  --set secrets.apiKey="$MAGIC_API_KEY" \
+  --set postgresql.auth.password="$(openssl rand -hex 16)"
+
+# 4. Verify
+kubectl -n magic rollout status deploy/magic
+kubectl -n magic port-forward svc/magic 8080:80 &
+curl -s http://localhost:8080/health
+```
+
+### Using an existing Postgres
+
+```bash
+helm install magic deploy/helm/magic/ \
+  --namespace magic --create-namespace \
+  --set postgresql.enabled=false \
+  --set secrets.apiKey="$MAGIC_API_KEY" \
+  --set secrets.postgresUrl="postgres://user:pass@db.example.com:5432/magic?sslmode=require"
+```
+
+### Using an externally-managed Secret (Sealed Secrets, External Secrets, Vault)
+
+```bash
+# Create secret out-of-band, then:
+helm install magic deploy/helm/magic/ \
+  --namespace magic \
+  --set secrets.existingSecret=magic-prod-creds \
+  ...
+```
+
+The referenced Secret MUST contain keys `MAGIC_API_KEY` and (optionally) `MAGIC_POSTGRES_URL`.
+
+### Upgrade
+
+```bash
+helm upgrade magic deploy/helm/magic/ -n magic --reuse-values
+```
+
+### Rollback
+
+```bash
+helm history magic -n magic
+helm rollback magic <REVISION> -n magic
+```
+
+### Uninstall
+
+```bash
+helm uninstall magic -n magic
+# Postgres PVC is retained — delete explicitly if desired:
+kubectl -n magic delete pvc -l app.kubernetes.io/instance=magic
+```
+
+### Common overrides
+
+| Override | Default | Purpose |
+|----------|---------|---------|
+| `replicaCount` | `2` | Control-plane replicas (Postgres backend only) |
+| `image.tag` | `""` (→ appVersion) | Pin a specific image version |
+| `ingress.enabled` | `false` | Expose externally |
+| `autoscaling.enabled` | `false` | HPA on CPU |
+| `metrics.serviceMonitor.enabled` | `false` | Prometheus Operator scraping |
+| `networkPolicy.enabled` | `false` | Lock down ingress/egress |
+| `podDisruptionBudget.enabled` | `false` | Protect during node drain |
+
+See `deploy/helm/magic/values.yaml` for the full list.
+
+---
+
+## Option 2 — Plain manifests
+
+Good for ArgoCD / Flux without a Helm wrapper.
+
+```bash
+# 1. Create a real Secret (do NOT use secret.example.yaml as-is)
+kubectl apply -f deploy/k8s/namespace.yaml
+
+kubectl -n magic create secret generic magic \
+  --from-literal=MAGIC_API_KEY="$(openssl rand -hex 32)" \
+  --from-literal=MAGIC_POSTGRES_URL="postgres://..."
+
+# 2. Apply the rest
+kubectl apply -f deploy/k8s/configmap.yaml
+kubectl apply -f deploy/k8s/deployment.yaml
+kubectl apply -f deploy/k8s/service.yaml
+# Edit the host first:
+kubectl apply -f deploy/k8s/ingress.yaml
+
+# 3. Verify
+kubectl -n magic rollout status deploy/magic
+kubectl -n magic port-forward svc/magic 8080:80 &
+curl -s http://localhost:8080/health
+```
+
+**You must deploy PostgreSQL separately** (e.g. CloudNativePG, Zalando operator, RDS, Neon, Supabase) and reference it via `MAGIC_POSTGRES_URL`. The plain manifests intentionally don't bundle a database.
+
+---
+
+## Option 3 — Docker Compose
+
+For single-host dev / small self-hosted. See [docs-site/guide/deployment.md](../docs-site/guide/deployment.md).
+
+---
+
+## Production checklist
+
+- [ ] `MAGIC_API_KEY` generated fresh per environment, ≥ 32 chars
+- [ ] PostgreSQL backend (never in-memory or SQLite at scale)
+- [ ] `MAGIC_TRUSTED_PROXY=true` when behind ingress
+- [ ] TLS terminated at ingress (cert-manager or equivalent)
+- [ ] `ingress.nginx.kubernetes.io/proxy-buffering: "off"` for SSE endpoints
+- [ ] ServiceMonitor or scrape annotations pointing at `/metrics`
+- [ ] Alerts on `http_requests_total{code=~"5.."}` and `task_failed_total`
+- [ ] PodDisruptionBudget + PodAntiAffinity (both set by default in chart)
+- [ ] Resource requests/limits tuned against observed load
+- [ ] NetworkPolicy restricting ingress to your ingress controller
+- [ ] Backups for the Postgres volume
+
+---
+
+## Troubleshooting
+
+```bash
+# Pod status
+kubectl -n magic describe pod -l app.kubernetes.io/name=magic
+
+# Live logs
+kubectl -n magic logs -l app.kubernetes.io/name=magic --tail=100 -f
+
+# Verify env wiring
+kubectl -n magic exec deploy/magic -- env | grep ^MAGIC_
+
+# Hit the admin API through a port-forward
+kubectl -n magic port-forward svc/magic 8080:80 &
+curl -H "Authorization: Bearer $MAGIC_API_KEY" http://localhost:8080/api/v1/workers
+```
+
+If `/health` returns 503 and logs mention migrations, the Postgres DSN is likely wrong or the `vector` extension is missing. Use a `pgvector/pgvector`-compatible image.

+3. Enable external access:
+   - Set `ingress.enabled=true` plus `ingress.hosts`, OR
+   - Change `service.type` to `LoadBalancer` / `NodePort`.
+{{- end }}
+
+4. Retrieve the admin API key for CLI / SDK clients:
+
+{{- if .Values.secrets.existingSecret }}
+   kubectl get secret {{ .Values.secrets.existingSecret }} \
+     -n {{ .Release.Namespace }} \
+     -o jsonpath='{.data.MAGIC_API_KEY}' | base64 -d; echo

+{{- end }}
+
+{{- if .Values.postgresql.enabled }}
+
+5. PostgreSQL is deployed as a subchart. Check migrations ran:
+
+   kubectl logs deployment/{{ include "magic.fullname" . }} \
+     -n {{ .Release.Namespace }} | grep -i migration
+
+   NOTE: Semantic search requires pgvector. The default chart pins
+   `pgvector/pgvector:pg16` so `CREATE EXTENSION vector` will succeed.
+{{- end }}

+
+Uninstall (Postgres PVC is NOT deleted automatically):
+  helm uninstall {{ .Release.Name }} --namespace {{ .Release.Namespace }}
+
+Troubleshooting:
+  kubectl describe pod -l app.kubernetes.io/instance={{ .Release.Name }} \
+    -n {{ .Release.Namespace }}
+  kubectl logs -l app.kubernetes.io/instance={{ .Release.Name }} \

+# MagiC Observability Stack
+
+Standalone Grafana + Prometheus + MagiC + PostgreSQL for local testing and reference deployments.
+
+## Quick start
+
+```bash
+# From repo root:
+docker compose -f deploy/docker-compose.observability.yml up -d
+
+# Wait ~30s for everything to become healthy, then:
+open http://localhost:3000    # Grafana (admin / admin)
+open http://localhost:9090    # Prometheus
+open http://localhost:8080/metrics   # raw MagiC metrics
+```
+
+Change the admin password:
+
+```bash
+GRAFANA_ADMIN_PASSWORD='strong-pass' \
+POSTGRES_PASSWORD='strong-db-pass' \
+MAGIC_API_KEY='strong-api-key' \
+docker compose -f deploy/docker-compose.observability.yml up -d
+```
+
+## Port map
+
+| Port  | Service          | Notes |
+|-------|------------------|-------|
+| 3000  | Grafana          | admin / `$GRAFANA_ADMIN_PASSWORD` (default `admin`) |
+| 9090  | Prometheus       | TSDB + alert rules |
+| 8080  | MagiC Gateway    | `GET /metrics` (Prometheus), `GET /health`, `/api/v1/*` |
+| 5432  | PostgreSQL       | not exposed externally; internal network only |
+| 9093  | Alertmanager     | optional, commented |
+| 16686 | Jaeger UI        | optional, commented (awaits OTel tracing) |
+
+## What ships out of the box
+
+**Dashboards** (auto-provisioned into the `MagiC` folder):
+
+- **MagiC Framework Overview** (`magic-overview.json`) — task rate, error rate, latency quantiles, active workers, worker load, cost/hour, webhook success rate, queue depth, rate-limit hits, SSE stream count.
+- **MagiC Costs & Budgets** (`magic-costs.json`) — 24h/7d spend, avg cost per task, spend rate, top cost workers, top cost orgs, cost leaderboard.
+
+Both are wired to the provisioned **Prometheus** datasource and expose `$org` / `$worker` template variables.
+
+**Alerts** (`deploy/prometheus/alerts.yaml`, group `magic.rules`):
+
+| Alert | Severity | Trigger |
+|---|---|---|
+| `MagicHighErrorRate` | warning | Task failure rate > 5% for 5m |
+| `MagicHighLatency` | warning | Task p99 > 30s for 10m |
+| `MagicWebhookDeliveryFailures` | warning | Webhook failed/dead rate > 10% for 10m |
+| `MagicBudgetExceeded` | critical | Any `budget.exceeded` event delivered (auto-pause fired) |
+| `MagicWorkerOffline` | warning | `magic_worker_heartbeat_lag_seconds > 300` for 2m |
+| `MagicNoWorkersAvailable` | critical | Task failures while `magic_workers_active == 0` |
+| `MagicDLQGrowing` | warning | > 100 dead webhook deliveries / hour |
+| `MagicRateLimitPressure` | info | Any endpoint rejecting > 1 req/s for 10m |
+
+Severities follow the convention:
+
+- **critical** — page immediately (data loss, production outage, budget blown).
+- **warning** — human response within an hour (latency, elevated error rate).
+- **info** — awareness / ticket (capacity pressure).
+
+All annotations include a `runbook_url` placeholder — replace with your real runbook location.
+
+## SLO suggestions
+
+| SLI | Target | PromQL |
+|-----|--------|--------|
+| Task success rate | 99% rolling 30d | `1 - sum(increase(magic_tasks_total{status="failed"}[30d])) / sum(increase(magic_tasks_total[30d]))` |
+| Task latency (p99) | < 10s | `histogram_quantile(0.99, sum by (le) (rate(magic_task_duration_seconds_bucket[5m])))` |
+| Webhook delivery | 99.5% | `1 - sum(rate(magic_webhook_deliveries_total{status=~"failed|dead"}[30d])) / sum(rate(magic_webhook_deliveries_total[30d]))` |
+| Gateway availability | 99.9% | from your probe / black-box exporter, not in-band |
+
+Error budget examples (30d):
+
+- 99.0% success → 7h 12m budget
+- 99.5% → 3h 36m
+- 99.9% → 43m
+
+## Importing dashboards manually
+
+If you're using your own Grafana:
+
+```bash
+# From your Grafana UI:
+# Dashboards → New → Import → Upload JSON
+# Pick deploy/grafana/dashboards/magic-overview.json
+# Pick deploy/grafana/dashboards/magic-costs.json
+# Select your Prometheus datasource when prompted.
+```
+
+Or copy the provisioning bits:
+
+```bash
+cp -r deploy/grafana/provisioning/* /etc/grafana/provisioning/
+cp deploy/grafana/dashboards/*.json /var/lib/grafana/dashboards/
+systemctl restart grafana-server
+```
+
+## Wiring alerts to Slack / PagerDuty
+
+Uncomment the `alertmanager` service in `docker-compose.observability.yml`,
+then create `deploy/alertmanager/alertmanager.yml`, for example:
+
+```yaml
+route:
+  receiver: slack
+  group_by: [alertname, component]
+  routes:
+    - matchers: [severity="critical"]
+      receiver: pagerduty
+
+receivers:
+  - name: slack
+    slack_configs:
+      - api_url: "https://hooks.slack.com/services/XXX/YYY/ZZZ"
+        channel: "#magic-alerts"
+  - name: pagerduty
+    pagerduty_configs:
+      - service_key: "YOUR_PD_INTEGRATION_KEY"
+```
+
+Then restart the stack.

+Taken from `core/internal/monitor/metrics.go` — don't guess metric names, grep that file if unsure.
+
+| Metric | Type | Labels |
+|--------|------|--------|
+| `magic_tasks_total` | counter | `type`, `status`, `worker` |
+| `magic_task_duration_seconds` | histogram | `type`, `worker` (not yet populated by code — see note) |
+| `magic_workers_active` | gauge | `org` |
+| `magic_worker_heartbeat_lag_seconds` | gauge | `worker` (not yet populated — see note) |
+| `magic_cost_total_usd` | counter | `org`, `worker` |
+| `magic_workflow_steps_total` | counter | `status` |
+| `magic_workflows_active` | gauge | — |
+| `magic_knowledge_queries_total` | counter | `type` (`keyword` / `semantic`) |
+| `magic_knowledge_entries_total` | gauge | — |
+| `magic_rate_limit_hits_total` | counter | `endpoint` |
+| `magic_webhook_deliveries_total` | counter | `status` (`delivered` / `failed` / `dead`) |
+| `magic_webhook_delivery_duration_seconds` | histogram | — |
+| `magic_streams_active` | gauge | — |
+| `magic_stream_duration_seconds` | histogram | — |
+| `magic_events_dropped_total` | counter | — (not yet populated — see note) |
+
+**Note:** `magic_task_duration_seconds`, `magic_worker_heartbeat_lag_seconds`, and `magic_events_dropped_total` are declared but not currently populated by the code. Related dashboard panels / alert rules are left in place as forward-looking; they stay silent (no series) until the corresponding `.Observe()` / `.Set()` / `.Inc()` calls are wired up. File an issue against `core/internal/monitor/` if you need them active.
+
+## Troubleshooting
+
+| Symptom | Likely cause | Fix |
+|---|---|---|
+| Grafana shows "No data" | Prometheus can't reach MagiC | `docker compose logs prometheus` — look for scrape errors |
+| Dashboards missing | Provisioning path wrong | Check `deploy/grafana/provisioning/dashboards/magic.yaml` path matches container mount |
+| Alerts never fire | Rule file not loaded | `curl http://localhost:9090/api/v1/rules` to confirm rules are loaded |
+| `MagicHighLatency` silent | Task duration histogram empty | Expected today — see note above |

+# MagiC Performance Benchmarks — v0.8 Baseline
+
+*April 18, 2026 — Preliminary results, reproduce before quoting.*
+
+When we positioned MagiC as "Kubernetes for AI agents", the first question from
+every enterprise evaluation team was the same: **how does it compare to
+Temporal, Dapr Workflows, and Ray Serve?** This post publishes the first
+baseline of our benchmark suite so that comparison can start happening in the
+open, on shared methodology, rather than in vendor-supplied PowerPoint.
+
+The numbers below are **preliminary**. They were produced on a synthetic run
+against placeholder hardware; they describe the *shape* of the output, not a
+measured result. The value of publishing now is that the **methodology,
+scripts, and scenarios are frozen** and anyone can reproduce — and contradict —
+our numbers. The goal for v0.9 is to replace every cell in the table below
+with a real measurement that links to its `results/vX.Y.Z-*.md` file.
+
+---
+
+## Methodology
+
+All benchmarks live in [`benchmarks/`](../../benchmarks/) with one scenario
+per file:
+
+- `throughput.md` — peak tasks/sec with 1 / 10 / 100 workers
+- `latency.md` — p50 / p95 / p99 at a sustained 100 rps
+- `fanout.md` — 100-step workflow, parallel vs sequential
+- `durability.md` — retry success rate under induced worker failure
+- `cost-tracking.md` — spend accounting accuracy under concurrent load
+
+The reference rig is deliberately modest so results are reproducible on a
+laptop:
+
+- 4 physical cores, x86_64
+- 8 GB RAM, NVMe SSD
+- Linux 6.x, Go 1.25, Postgres 16 (loopback socket)
+- Loopback networking only — we are measuring MagiC, not the NIC
+
+Every run:
+
+1. Spins up a clean stack via `benchmarks/scripts/docker-compose.bench.yml`
+   (tmpfs-backed Postgres for deterministic cold starts).
+2. Registers N echo workers that sleep 10 ms per call to simulate lightweight
+   real-world work without drowning dispatch overhead.
+3. Drives load from `benchmarks/scripts/load.py` (asyncio + httpx, token-bucket
+   rate limiter, coordinated-omission-safe timing).
+4. Records per-task CSV and a markdown summary into `benchmarks/results/`.
+
+Each scenario is run three times; we publish the median.
+
+---
+
+## Preliminary results (synthetic placeholders — v0.8.0)
+
+> These numbers are illustrative only. They are taken from the template in
+> `benchmarks/results/v0.8.0-baseline.md` and exist to show the output
+> structure and order of magnitude we expect. Do not cite externally until
+> replaced with measured values.
+
+| Scenario | Metric | Synthetic value |
+|----------|--------|-----------------|
+| Throughput (10 workers) | tasks/sec | **2,500** |
+| Latency @ 100 rps | p50 / p95 / p99 ms | **12 / 28 / 45** |
+| Workflow fan-out (100 steps, parallel) | wall-clock | **3.2 s** |
+| Workflow fan-out (100 steps, sequential) | wall-clock | **~105 s** |
+| Durability (10% fault injection) | DLQ rate / lost rate | **~0.1% / 0%** |
+| Cost tracking drift | \|reported − expected\| / expected | **< 1e-6** |
+| Router latency @ 1000 workers | ns/op (Go microbench) | **~400,000** |
+
+## Comparison with other orchestration frameworks
+
+This is the comparison the community has asked for. We are explicitly **not
+populating it yet** — we want these cells filled by third parties running the
+same `benchmarks/scripts/load.py` against each system, not by us eyeballing
+blog posts.
+
+| Framework | Throughput (10 workers) | p99 @ 100 rps | Fan-out 100 (parallel) |
+|-----------|-------------------------|---------------|-------------------------|
+| **MagiC v0.8** | pending | pending | pending |
+| Temporal | TBD — awaiting community submission | TBD | TBD |
+| Dapr Workflows | TBD — awaiting community submission | TBD | TBD |
+| Ray Serve | TBD — awaiting community submission | TBD | TBD |
+
+If you run MagiC alongside any of the above on the reference rig (or a
+well-documented deviation), please open a PR adding a
+`benchmarks/results/comparisons/<framework>-vX.Y.md` file. We will merge
+honest numbers even when MagiC loses — the only thing we will reject is
+undocumented setups.
+
+---
+
+## Reproducibility
+
+```bash
+# Go micro-benchmarks (no external deps)
+make bench-go
+
+# End-to-end load test (needs running gateway + echo workers)
+docker compose -f benchmarks/scripts/docker-compose.bench.yml up -d
+make bench-load
+```
+
+The `make bench` target runs the Go side only; the load tests are separate
+because they need a live stack and can take minutes to stabilise.
+
+---
+
+## Caveats
+
+- **Numbers vary by environment.** The reference rig is a laptop-class CPU.
+  Cloud VMs with noisy neighbours will look worse; bare metal with PCIe
+  Postgres will look better.
+- **LLM latency is excluded.** MagiC is infrastructure; the workers call
+  whatever LLM they choose. We benchmark orchestration overhead, which is
+  what the framework actually controls.
+- **GC pauses dominate the tail.** Go's default GC produces occasional
+  50 ms+ pauses under sustained allocation. We report the raw distribution
+  rather than trimming outliers; consumers can re-aggregate however they
+  prefer.
+- **Warm-up is excluded.** The first 30 seconds of each run are discarded so
+  connection pool warm-up and JIT-style cache effects do not bias the mean.
+
+---
+
+## Call to action
+
+The benchmarks are framework-independent: `load.py` talks HTTP, and any
+orchestration system exposing a similar submit+poll shape can be driven the
+same way. We would genuinely like:
+
+1. **Contradictions.** If your numbers are worse than ours, file an issue —
+   that is a regression we need to fix.
+2. **Comparisons.** Run the same scripts against Temporal / Dapr / Ray on
+   matched hardware and PR the results.
+3. **New scenarios.** Multi-tenant isolation, cold start after crash, and
+   cross-region dispatch are all missing from v0.8. Specs welcome.
+
+The repo is at `github.com/kienbui1995/magic`. Benchmark specs, scripts, and
+this blog post all live under source control, so numbers you publish today
+will still be comparable a year from now.

+# Case Studies
+
+Learn how teams use MagiC to orchestrate fleets of AI agents in production.
+
+---
+
+## Why Case Studies?
+
+Case studies are the best way to understand what's possible. They show:
+
+- **Real-world problems** — not toy examples
+- **Hard decisions** — trade-offs and lessons learned
+- **Quantified impact** — latency, cost, reliability improvements
+- **Implementation patterns** — how to wrap your agents, structure workers, scale to millions of tasks
+
+If you're evaluating MagiC, these are the stories that matter most.
+
+---
+
+## Current Cases
+
+> **Your story here.** We're looking for the first production case studies. If you've built with MagiC, we'd love to share your journey.
+
+---
+
+## How to Submit
+
+**Option 1: GitHub PR (preferred)**
+
+1. Copy `template.md` to a new file: `docs/case-studies/your-company-name.md`
+2. Fill in all sections (or most of them — no need to be perfect)
+3. Add a photo or logo if you'd like
+4. Open a pull request
+5. We'll review and merge within 1 week
+
+**Option 2: Email**
+
+Send a completed template to `hello@magic-ai.dev`. We'll add it to the repo and credit you.
+
+**Option 3: Recorded Interview**
+
+If writing isn't your style, we can do a 30-minute video call and turn it into a written case study.
+
+---
+
+## Template
+
+Use `template.md` as your guide. It covers:
+
+- **Company Profile** — who you are, what you built
+- **The Problem** — what you were trying to solve
+- **Why MagiC** — decision factors vs. alternatives
+- **Architecture** — your deployment (workers, storage, routing)
+- **Implementation** — how you integrated it, effort required
+- **Results** — quantified impact (latency, cost, uptime, dev velocity)
+- **Lessons Learned** — what worked, what you'd do differently
+- **Roadmap** — where you're heading next
+- **Quotes** — soundbites from your team
+
+You don't need to fill in every section. Skip what's not applicable. 500–2000 words is typical; we'll edit for clarity.
+
+---
+
+## What We're Looking For
+
+**Good fits:**
+
+- ✅ Production deployments (not prototype / POC)
+- ✅ Any industry (no restrictions)
+- ✅ Any agent framework (CrewAI, LangChain, AutoGen, custom)
+- ✅ Quantified results (even if modest)
+- ✅ Learning — what worked, what didn't
+- ✅ Public companies and startups alike
+
+**Not needed:**
+
+- ❌ You don't have to open-source your agents
+- ❌ You don't have to share proprietary metrics
+- ❌ You don't have to be a customer (fork + evaluate is fine)
+- ❌ You don't have to be a big name (grassroots stories welcomed)
+
+---
+
+## Examples of Great Case Studies
+
+(These are placeholders — add real ones as you receive submissions)
+
+- **E-Commerce Co** — "From chaos to orchestration: How we scaled from 10K to 500K tasks/day with MagiC"
+- **Healthcare AI** — "HIPAA-compliant multi-tenant agent fleet with RLS and audit logs"
+- **Media Company** — "Replacing 50 shell scripts with 5 MagiC workers + 30% cost savings"
+- **Research Lab** — "Real-time multi-agent consensus for scientific analysis"
+
+---
+
+## FAQ
+
+**Q: Will you share my company's internal metrics?**
+A: Only what you choose to include. We respect confidentiality. Feel free to anonymize or round numbers.
+
+**Q: Can I update my case study later?**
+A: Yes. Open a PR with updates, or email us to revise.
+
+**Q: Who owns the content?**
+A: You do. We ask for permission to publish and reproduce it. You can republish it anywhere.
+
+**Q: Can I link to my blog post instead?**
+A: Sure. If you have a detailed writeup elsewhere, we'll link to it and add a summary here.
+
+**Q: What if MagiC didn't work perfectly for us?**
+A: Tell us. Honest feedback (including challenges) is more valuable than pure praise. We want to improve, and real stories help.

+
+## The Problem
+
+**What problem were you solving?**
+
+Describe the business challenge:
+- What were you trying to build?
+- Why did existing solutions fall short?
+- What was the technical debt or scaling challenge?
+
+Example:
+> We were running 20+ AI agents for content moderation, customer support, and data extraction. Each agent was a monolithic Python script with hardcoded retry logic, no cost tracking, and no way to balance load across workers. When one agent crashed, the entire pipeline went down.
+
+**Scale & Context:**
+- Tasks per day / week / month
+- Number of agents / workers
+- Primary use cases (e.g., content moderation, customer support, research)
+- Pain points with previous approach
+
+---
+
+## Why MagiC?
+
+**Why did you choose MagiC instead of alternatives?**
+
+Consider:
+- Temporal (if you use that)
+- Dapr (distributed application runtime)
+- Build-your-own orchestration
+- Other frameworks (Celery, RQ, Kafka, etc.)
+
+Example comparison:
+> We evaluated Temporal, but its learning curve was steep, and it didn't understand LLM semantics (token counting, cost tracking, fallback strategies). We considered building our own scheduler, but that's a 2-month project. MagiC gave us worker orchestration + cost tracking + RBAC out of the box. One engineer integrated the first agent in a day.
+
+**Key decision factors:**
+- Built-in AI features (cost tracking, token counting, semantic search)
+- Language support (Go core, Python/Go/TS SDKs)
+- Multi-tenancy (teams, RBAC, billing)
+- Extensibility (plugins for routing, evaluation, policies)
+- Operational maturity (persistence, monitoring, resilience)

+```
+
+**Key components:**
+- How many workers / agents?
+- Storage backend (PostgreSQL, SQLite, in-memory)?
+- Routing strategy (best_match, round_robin, cheapest)?
+- Persistent features used (knowledge hub, webhooks, cost tracking)?
+
+---
+
+## Implementation
+
+**Workers deployed:**
+- Total count: [e.g., 15 workers]
+- Languages: [e.g., 8 Python, 4 Go, 3 TypeScript]
+- Frameworks wrapped:
+  - [e.g., 5 CrewAI crews]
+  - [e.g., 3 LangChain agents]
+  - [e.g., 2 AutoGen agents]
+  - [e.g., 2 custom HTTP servers]
+
+**Task volume:**
+- Baseline (QA/staging): [e.g., 500 tasks/day]
+- Peak (production): [e.g., 15K tasks/day]
+- Latency targets: [e.g., P50: 200ms, P95: 2s, P99: 10s]
+
+**Key configuration decisions:**
+
+> **Cost limit per task:** We set `max_cost_per_task = $0.50` to prevent runaway OpenAI bills. Agents that exceed this get auto-paused by MagiC's cost controller until the next day.
+
+> **Routing strategy:** Started with `best_match` (find agent with highest capability score), switched to `cheapest` once we had cost data. Saved 30% on LLM spend.
+
+> **Persistence:** Used SQLite in dev, switched to PostgreSQL with read replicas in prod. RLS (row-level security) ensures team A can't see team B's tasks.
+
+> **Multi-tenancy:** Each customer org has its own token + API key. Webhooks send cost reports to their Slack channel daily.
+
+**Integration effort:**
+- Time to first worker integrated: [e.g., 4 hours]
+- Time to productionize (auth, monitoring, backups): [e.g., 1 week]
+- Team size working on integration: [e.g., 2 engineers]

+## Results
+
+### Quantitative
+
+| Metric | Before MagiC | After MagiC | Impact |
+|--------|--------------|------------|--------|
+| Task latency (P95) | 5s | 500ms | 10x faster |
+| Task failure rate | 15% | 0.5% | 30x more reliable |
+| Cost per task | $0.12 | $0.08 | 33% cheaper |
+| Time to deploy new agent | 3 days | 2 hours | 36x faster |
+| Unplanned downtime / month | 6 hours | 0 | 100% uptime |
+| Ops cost (monitoring time) | 20 hrs/week | 2 hrs/week | 10x savings |
+
+### Qualitative
+
+**Developer experience:**
+> "Before MagiC, adding a new agent meant writing 500 lines of boilerplate (queues, retries, monitoring). Now it's 50 lines — just a `@worker.capability` decorator. Agents stay in their domain language (Python, JavaScript, etc.), and MagiC handles the hard parts."
+
+**Operational confidence:**
+> "We never worry about budget overruns or worker crashes anymore. MagiC's dashboard shows real-time costs and worker health. When an agent is unhealthy, we get a Slack alert within seconds. We sleep better."
+
+**Time to market:**
+> "Three months ago, adding a new agent to production took a week of engineering + a week of QA. Now it's 1 day. We shipped 5 new agents last quarter instead of 1."
+
+---
+
+## Lessons Learned
+
+**What worked well:**
+
+1. **Wrapping, not rewriting.** We didn't touch the CrewAI crews or LangChain agents. We just wrapped them as MagiC workers. Zero risk of breaking existing logic.
+
+2. **Cost transparency.** Once we could see per-agent costs, we optimized prompts and model selection. Saved $2K/month just by switching from GPT-4 to GPT-3.5 for certain agents.
+
+3. **RBAC from day one.** We set up team-based role bindings early. Prevented a customer from accessing another's audit logs (a compliance issue that could've been expensive).
+
+**What we'd do differently:**
+
+1. **Cluster mode earlier.** We ran a single MagiC instance for 3 months, then hit latency walls at 10K tasks/day. Switched to 3-pod cluster with PostgreSQL, and problems disappeared. Could've done this from month 1.
+
+2. **Monitoring from the start.** We didn't set up Prometheus until month 2. Spent days debugging task latency blind. Now Grafana dashboards are part of day 1 setup.
+
+3. **Knowledge hub sooner.** We built a manual knowledge cache before discovering MagiC's semantic search. Replaced it with pgvector in a day. Agents now share context automatically.
+
+---
+
+## Looking Forward
+
+**Roadmap:**
+
+- [ ] Add 10 more agents (targeting 40 total by Q3 2026)
+- [ ] Migrate to OIDC authentication (replace API keys)
+- [ ] Multi-region deployment (Asia + US + EU)
+- [ ] Open-source our agent framework for the community
+- [ ] Implement dynamic routing (AI-driven agent selection based on historical performance)
+
+**Scaling plans:**
+
+> We expect to handle 100K tasks/day by end of 2026. PostgreSQL + Redis + multi-region Kubernetes should handle that. We're also exploring worker auto-scaling based on queue depth.

+# Shell Completion
+
+The `magic` CLI ships with completion scripts for **bash**, **zsh**, and **fish**. Each script completes subcommand names (`serve`, `workers`, `tasks`, `submit`, `status`, `completion`, `version`, `help`) plus serve flags (`--config`) and completion shell arguments.
+
+The scripts are emitted by the binary itself — no extra install artefact — so upgrading MagiC refreshes completion automatically.
+
+## bash
+
+System-wide:
+
+```bash
+magic completion bash | sudo tee /etc/bash_completion.d/magic > /dev/null
+```
+
+User-local (no sudo):
+
+```bash
+mkdir -p ~/.local/share/bash-completion/completions
+magic completion bash > ~/.local/share/bash-completion/completions/magic
+```
+
+Then open a new shell (or `source` the file).
+
+## zsh
+
+```bash
+magic completion zsh > "${fpath[1]}/_magic"
+```
+
+If you use a framework (oh-my-zsh, prezto, zinit), drop the file into its custom completions directory instead — e.g. `~/.oh-my-zsh/completions/_magic`. Reload with:
+
+```bash
+autoload -U compinit && compinit
+```
+
+## fish
+
+```bash
+magic completion fish > ~/.config/fish/completions/magic.fish
+```
+
+Fish picks up new completion files without reloading.
+
+## Verify
+
+Type `magic <TAB>` — you should see the seven subcommands. `magic serve --<TAB>` should offer `--config`. `magic completion <TAB>` should offer `bash / zsh / fish`.

+# Config File Reference
+
+`magic serve` reads an optional YAML config file. The file is **entirely optional** — every setting also has an environment variable and/or a safe default.
+
+## Discovery
+
+1. `--config <path>` / `-c <path>` — explicit, wins over auto-discovery.
+2. `./magic.yaml` — auto-discovered from the working directory.
+3. No file — defaults + env vars only.
+
+## Precedence
+
+For every setting the effective value is chosen with this priority (highest first):
+
+1. **CLI flag** (e.g. `--config`)
+2. **Environment variable** (e.g. `MAGIC_API_KEY`, `MAGIC_POSTGRES_URL`)
+3. **Config file** value
+4. **Built-in default** (e.g. `port: 8080`, `log_level: info`)
+
+This means you can commit a checked-in `magic.yaml` with sensible defaults and override sensitive values in production via env vars, without editing the file.
+
+## Env interpolation
+
+Values inside the YAML file support `${VAR}` and `$VAR` expansion against the process environment, evaluated **before** the file is parsed:
+
+```yaml
+api_key: "${MAGIC_API_KEY}"
+store:
+  postgres_url: "${MAGIC_POSTGRES_URL}"
+```
+
+Missing variables expand to an empty string. Prefer the bracketed form when the value sits next to other characters.
+

+| `trusted_proxy`               | `MAGIC_TRUSTED_PROXY=true`    | `false` |
+
+## Security notes
+
+- Never commit a `magic.yaml` that contains plaintext credentials. Use env interpolation (`${MAGIC_API_KEY}`) and inject the env vars at runtime (Docker secrets, k8s Secret, systemd `EnvironmentFile`, …).
+- Credentials (`MAGIC_API_KEY`, `MAGIC_POSTGRES_URL`, `OPENAI_API_KEY`, `ANTHROPIC_API_KEY`) are resolved via the configured `secrets.Provider` so backends like Vault or AWS Secrets Manager can replace the env-var resolver without code changes. See `docs/security/secrets.md`.
+- `MAGIC_API_KEY` must be at least 32 characters when set — generate one with `openssl rand -hex 32`.

+# GDPR Compliance Guide
+
+> **Disclaimer.** This document is provided for engineering and architectural guidance only. It is **not legal advice.** GDPR compliance depends on your specific use case, data, jurisdiction, and contracts. Consult a qualified Data Protection Officer (DPO) or lawyer before making compliance claims about your deployment.
+
+## Purpose
+
+This guide describes how MagiC — as infrastructure software — supports operators who are subject to the [EU General Data Protection Regulation (GDPR)](https://gdpr-info.eu/) and similar regimes (UK GDPR, Swiss revDPA, California CCPA/CPRA by analogy).
+
+## Role Under GDPR
+
+| Role | Who is it? |
+|------|-----------|
+| **Data Controller** | The organization deploying MagiC and deciding what personal data to process (**you**, the operator). |
+| **Data Processor** | MagiC the software, running under the Controller's control. The MagiC project authors act as a processor only when providing managed services (future SaaS). |
+| **Sub-processors** | Any third-party services the Controller configures MagiC to call — LLM providers, managed Postgres, vector DBs, observability backends. |
+
+Because MagiC is self-hostable open-source software, **you are the Controller** for any personal data passing through your deployment. The MagiC maintainers do not process your data.
+
+## Data Subject Rights — How MagiC Supports Each
+
+| Right | GDPR Art. | How MagiC helps | Gaps / operator responsibility |
+|-------|-----------|-----------------|--------------------------------|
+| **Access** (copy of personal data) | Art. 15 | Audit log (`GET /api/v1/orgs/{orgID}/audit`) records every action. Task inputs/outputs are stored in the `tasks` table (JSONB). | **TODO:** implement data export endpoint `GET /api/v1/orgs/{orgID}/export` that bundles all org-scoped rows. Until then, use `pg_dump` with filters. |
+| **Rectification** | Art. 16 | Entities are stored in JSONB and can be updated via admin SQL. | No UI for data subject self-serve correction. |
+| **Erasure / "right to be forgotten"** | Art. 17 | `DELETE /api/v1/workers/{id}`; cascading queries by `org_id` on every table. | **TODO:** implement a cascading `DELETE /api/v1/orgs/{orgID}/subjects/{subjectID}` that removes tasks, audit entries, knowledge entries, memory turns, prompts referencing the subject. Current workaround: org-level delete + redaction SQL. |
+| **Restriction of processing** | Art. 18 | Worker pause via cost controller (`budget.exceeded`). Per-org policy engine can block specific capabilities. | No per-subject processing flag yet. |
+| **Portability** | Art. 20 | Same as Access — JSONB blobs are trivially exportable to JSON. | See Access TODO. |
+| **Objection** | Art. 21 | Policy Engine can block tasks by capability or metadata. | No UI. |
+| **Automated decision-making / profiling** | Art. 22 | Task results are auditable. Evaluator output is logged. | Operator must inform subjects when AI makes automated decisions about them. |
+
+## Lawful Basis
+
+MagiC does not choose the lawful basis — that is the Controller's responsibility. Common bases for AI-assisted workloads:
+
+- **Contract** (Art. 6(1)(b)) — processing required to fulfil a service the subject requested.
+- **Legitimate interest** (Art. 6(1)(f)) — requires a documented LIA (Legitimate Interest Assessment). Caveat: high-risk AI processing often fails the balancing test.
+- **Consent** (Art. 6(1)(a)) — explicit opt-in. Required for most marketing/personalization AI use.
+
+Document your basis in your DPIA and privacy notice. Do **not** rely on "legitimate interest" by default for profiling or sensitive data.
+
+## Data Retention
+
+Retention is deployment-configurable. MagiC ships with **no automatic expiry** — entities live in PostgreSQL until deleted.
+
+Recommended baseline:
+
+| Entity | Recommended retention | Reason |
+|--------|-----------------------|--------|
+| Tasks (completed/failed) | 90 days rolling | Debug + audit, then purge |
+| Audit log | 12 months minimum | Matches SOC 2 baseline; some regulators require 3 years |
+| Workflow records | 90 days | Debug only |
+| Knowledge entries | Indefinite until explicit deletion | Business data owned by Controller |
+| Memory turns (chat history) | Configurable per session | Typically 30-90 days unless explicit retention use case |
+| Webhook deliveries | 30 days | Debug only |
+| Cost records | 12 months | Billing reconciliation |
+
+Implement retention with a scheduled purge job (`pg_cron`, k8s `CronJob`) — there is no built-in reaper yet.
+
+## Data Location
+
+MagiC runs where you deploy it. Data residency is controlled by:
+
+- **Database location** — `MAGIC_POSTGRES_URL` points to your managed or self-hosted Postgres. Pin the region.
+- **Worker endpoints** — workers run as external HTTP servers. Audit their deployment region.
+- **LLM providers** — all LLM calls go through the LLM Gateway. Check each provider's data-processing location and BAA/DPA terms.
+
+For EU data, keep Postgres and workers in the EU. Most major LLM providers now offer EU regions — configure the gateway accordingly.
+
+## Sub-processors
+
+MagiC itself is a processor. Any service the Controller integrates is a sub-processor. Publish a sub-processor list to data subjects; below is a **template** you must complete before publishing.
+
+| Sub-processor | Purpose | Data processed | Location | DPA |
+|---------------|---------|----------------|----------|-----|
+| PostgreSQL provider (e.g., AWS RDS, Supabase, Neon) | Primary storage | All entities | _TODO — your region_ | _Link to your DPA_ |
+| LLM provider(s) (OpenAI, Anthropic, Google, Ollama self-hosted, etc.) | Model inference | Task input/output passed to the model | Per-provider, varies | Per-provider |
+| Object storage (if used) | Large artifacts | Task payloads over size threshold | _TODO_ | _TODO_ |
+| Observability (Prometheus, logs, APM) | Metrics and logs | Metadata, request IDs, error messages — **no PII if properly configured** | _TODO_ | _TODO_ |
+| Email / SMTP (for alerts) | Notifications | Operator email addresses | _TODO — e.g., AWS SES_ | _TODO_ |
+| **TODO:** _add your actual sub-processors_ | | | | |
+
+Review this list when you change providers. Notify data subjects of material changes, per Art. 28.
+
+## Breach Notification
+
+GDPR Art. 33 requires notification of a personal data breach to the supervisory authority **within 72 hours** of awareness, with notification to affected subjects if risk is high (Art. 34).
+
+MagiC support for breach detection:
+
+- **Audit log** — `GET /api/v1/orgs/{orgID}/audit` captures access patterns.
+- **Rate-limit metrics** — `magic_ratelimit_hits_total` catches brute-force.
+- **Webhook events** — subscribe to `task.failed`, `audit.denied`, `budget.exceeded` and forward to your SIEM.
+- **Prometheus** — `/metrics` exposes request/latency/error counters.
+
+Breach response — see the [Incident Response Runbook](../ops/runbook-incident.md). Adapt the templates there for regulator-facing notifications. Maintain a breach log with:
+
+- What happened (timeline, detection path).
+- Nature of data and approximate number of subjects affected.
+- Likely consequences.
+- Mitigation taken and planned.
+
+## Data Protection Impact Assessment (DPIA) — Template
+
+Run a DPIA under GDPR Art. 35 when processing is likely to result in high risk — which includes "systematic evaluation of personal aspects using automated processing, including profiling" and "large-scale processing of special categories" (Art. 9 data). Most production AI agent workloads cross one of these triggers.
+
+Minimum DPIA skeleton:
+
+1. **Description** — what does the system do? Which MagiC modules are in scope?
+2. **Necessity and proportionality** — why is processing needed? Could a less invasive approach work?
+3. **Risks to data subjects** — re-identification, unauthorized access, model leakage, biased outputs.
+4. **Mitigations** — RBAC roles, audit log review cadence, encryption in transit/at rest, retention, model choice, human-in-the-loop gates.
+5. **Residual risk** — what is left after mitigations? Is it acceptable?
+6. **Consultation** — DPO review, and supervisory authority consultation under Art. 36 if residual risk remains high.
+
+A short DPIA (4-6 pages) is fine for most deployments. Keep it updated with material changes.
+
+## Technical Safeguards Checklist
+
+- [ ] TLS on all external endpoints (MagiC does not terminate TLS itself — use a proxy such as Cloudflare, Traefik, nginx, or the cloud load balancer).
+- [ ] Encryption at rest — enable Postgres TDE / disk encryption.
+- [ ] RBAC bindings created for every org (otherwise MagiC opens access — see `core/internal/rbac/rbac.go`).

+# HIPAA Considerations
+
+> **Disclaimer.** This document is engineering guidance and is **not legal advice**. HIPAA compliance is jurisdiction-specific (United States), depends on your role (Covered Entity vs. Business Associate), and requires legal review. Engage a qualified healthcare compliance attorney before processing Protected Health Information (PHI) with any AI system, including MagiC.
+
+## The Most Important Line
+
+**MagiC open-source is not HIPAA-compliant out of the box.** It is a toolkit that can be part of a HIPAA-compliant deployment if — and only if — the operator designs, deploys, contracts, and operates it according to HIPAA's Administrative, Physical, and Technical Safeguards.
+
+If you are processing PHI, you must:
+
+1. Sign a **Business Associate Agreement (BAA)** with every sub-processor that will touch PHI — including your LLM provider, vector DB, Postgres provider, and log/observability provider.
+2. Implement all three categories of HIPAA safeguards.
+3. Conduct a documented risk analysis (45 CFR § 164.308(a)(1)(ii)(A)).
+4. Have legal counsel review.
+
+## Business Associate Agreements (BAA)
+
+HIPAA requires a BAA with each Business Associate. For AI systems the critical ones are:
+
+| Role | Who it is | BAA required? |
+|------|-----------|---------------|
+| **LLM provider** | OpenAI, Anthropic, Google, Azure OpenAI, etc. | **Yes** — each provider's BAA is separate and often requires an enterprise contract tier. Do **not** send PHI to free or consumer API tiers. |
+| **Vector DB / semantic search** | Pinecone, Weaviate, Qdrant Cloud, managed pgvector. | Yes. |
+| **Database provider** | AWS RDS, Google Cloud SQL, Azure DB, Supabase (enterprise). | Yes — most managed Postgres providers offer a BAA on enterprise tiers only. |
+| **Observability** | Datadog, Sentry, New Relic, Splunk. | Yes, if logs or metrics can contain PHI. Prefer PHI-free logging. |
+| **Cloud infra (IaaS)** | AWS, GCP, Azure. | Yes — all three major clouds offer BAAs. |
+| **MagiC maintainers** | The MagiC open-source project. | **No** — the maintainers do not run the software on your behalf. If / when a managed MagiC SaaS exists, a BAA option will be offered separately. |
+
+**Ollama / self-hosted open-source LLMs** are an alternative to external providers when no BAA can be obtained — the model runs inside your BAA boundary. Performance and quality tradeoffs apply.
+
+## PHI Handling Warnings
+
+- **Never** place PHI in `MAGIC_API_KEY`, worker names, capability names, or any URL path.
+- **Never** include PHI in Prometheus metric labels — they are low-cardinality and permanent.
+- **Never** include PHI in log messages or trace-attribute values. Redact before logging.
+- Task `input` and `output` fields **may** contain PHI if the deployment is fully inside a BAA boundary. Label such tasks with `metadata.contains_phi = true` so you can filter in audit review.
+- Knowledge entries and memory turns may persist PHI. Apply retention + deletion policies.
+- LLM Gateway fallback to an unsupported provider can leak PHI. Pin providers in your BAA and disable fallback to non-BAA providers.
+
+## Safeguards Checklist
+
+HIPAA Security Rule safeguards mapped to MagiC capabilities.
+
+### Administrative Safeguards (45 CFR § 164.308)
+
+| Safeguard | Operator action | MagiC support |
+|-----------|-----------------|---------------|
+| Security Management Process (risk analysis, risk management, sanction policy, activity review) | Document annual risk analysis. Define sanction policy. Review activity quarterly. | Audit log (`GET /api/v1/orgs/{orgID}/audit`) is your activity evidence source. |
+| Assigned Security Responsibility | Name a Security Officer. | N/A (process). |
+| Workforce Security (authorization, clearance, termination) | Document joiner/mover/leaver. Revoke access on termination. | `DELETE /api/v1/orgs/{orgID}/tokens/{id}`; remove role bindings. |
+| Information Access Management | Least-privilege role assignments. | RBAC roles `owner`/`admin`/`viewer`; policy engine for capability gating. |
+| Security Awareness and Training | Annual training for engineers and support staff. | N/A (process). |
+| Security Incident Procedures | Runbook + postmortem. | See [Incident Response Runbook](../ops/runbook-incident.md). |
+| Contingency Plan (backup, disaster recovery, emergency mode) | Document + test. | See [Backup & Restore](../ops/backup-restore.md) and [DR](../ops/dr.md). |
+| Evaluation | Periodic technical + non-technical evaluation. | Track in your compliance management system. |
+| Business Associate Contracts | Sign BAAs (see above). | N/A (contract). |
+
+### Physical Safeguards (45 CFR § 164.310)
+
+MagiC is software; physical safeguards are the responsibility of the IaaS provider and the operator's office policy. Ensure your cloud provider's BAA covers data-center access controls, workstation use, and device & media controls. Do not run MagiC on laptops that may touch PHI without full-disk encryption and MDM.
+
+### Technical Safeguards (45 CFR § 164.312)
+
+| Safeguard | MagiC control | Operator responsibility |
+|-----------|---------------|-------------------------|
+| **Access Control (§ 164.312(a)(1))** | RBAC with `owner/admin/viewer`; per-org isolation; worker tokens. | Enforce unique user IDs. Integrate with SSO/MFA for human subjects. Automatic logoff — configure at the client / UI layer. |
+| **Audit Controls (§ 164.312(b))** | `audit_log` table; bus subscriber records `worker.registered`, `task.routed`, `task.completed`, `task.failed`, etc. | Ship audit entries to an append-only archive (S3 Object Lock). Retain 6 years minimum (HIPAA documentation rule). Review regularly. |
+| **Integrity (§ 164.312(c)(1))** | Audit entries are immutable in-app (no update endpoint). Entities have IDs and timestamps. | Use WORM storage for archive. Consider hash-chained audit log (future MagiC feature). |
+| **Person or Entity Authentication (§ 164.312(d))** | `MAGIC_API_KEY` for API clients; worker tokens (hashed storage via `token_hash` column); `Authorization: Bearer` header. | Rotate tokens on schedule. Use SSO/MFA for human access paths. |
+| **Transmission Security (§ 164.312(e)(1))** | No TLS termination by MagiC itself. Outbound webhook calls can use HTTPS. SSRF protection blocks private IP ranges and DNS rebinding. | Terminate TLS at reverse proxy (nginx, Traefik, cloud LB, Cloudflare). Enforce TLS 1.2+, modern ciphers, HSTS. Internal traffic between MagiC and workers must also be TLS if crossing untrusted networks. |
+
+## Encryption
+
+HIPAA's encryption is "addressable" — you must implement it or document why not. In practice, encrypt always for PHI.
+
+- **In transit:** TLS 1.2 or higher on every hop. MagiC does not terminate TLS; your reverse proxy must.
+- **At rest:** enable Postgres tablespace or disk-level encryption. Managed Postgres providers typically enable this by default (verify with your provider's compliance documentation). Backup snapshots inherit encryption only if explicitly configured.
+- **Backups:** encrypted, with separate key management from the primary DB keys where possible.
+- **Keys:** stored in a KMS (AWS KMS, GCP KMS, Azure Key Vault, Vault). Never in environment variables committed to source control.
+
+## Minimum Necessary Rule
+
+HIPAA's Minimum Necessary standard (45 CFR § 164.502(b)) says you must limit PHI access and use to the minimum necessary for the task.
+
+MagiC mechanisms that help:
+
+- **RBAC viewer role** — read-only accounts for support / analytics.
+- **Policy Engine** — block capabilities or tags (`allowed_capabilities`, `blocked_capabilities`) from touching PHI-labeled tasks.
+- **Per-org isolation** — tenant boundary; cross-org access requires explicit binding.
+- **Audit log** — evidence for review.
+
+Operator responsibilities:
+
+- Redact PHI before passing to agents that don't need it.
+- Use the Evaluator to block outputs that leak unexpected PHI.
+- Restrict human access to audit log contents — it may contain PHI in request/response payloads.
+
+## Breach Notification
+
+HIPAA Breach Notification Rule (45 CFR §§ 164.400-414):
+
+- Notify affected individuals within **60 days** of discovery.
+- Notify HHS — within 60 days for breaches of 500+ individuals; annually for smaller breaches.
+- Media notification for breaches of 500+ in a single state.
+
+Use the [Incident Response Runbook](../ops/runbook-incident.md) as the operational backbone and add HIPAA-specific communication templates to your organization's incident plan.
+
+## Recommended Deployment Pattern for PHI
+
+```
+    [Clinical apps / EHR]
+           │ HTTPS
+           ▼
+    [TLS-terminating proxy — cloud LB / nginx / Traefik]
+           │
+           ▼
+    [MagiC core] ── audit log → [S3 Object Lock archive — BAA]
+       │
+       ├─► [Postgres — managed, BAA, encryption at rest, PITR]
+       │
+       └─► [Worker fleet, all in same BAA/VPC boundary]
+                  │
+                  └─► [LLM provider — enterprise tier with BAA]
+                      (or self-hosted Ollama inside VPC)
+```
+
+Key design rules:
+
+- Every component is inside the BAA perimeter.
+- No egress to non-BAA services for PHI-carrying traffic.
+- Observability stack (logs, metrics, traces) either inside the BAA perimeter or PHI-free by construction.

+# SOC 2 Type II Control Mapping
+
+> **Disclaimer.** This is engineering guidance, not an audit report. SOC 2 attestation is issued by an independent CPA after reviewing your controls and evidence over a 6-12 month observation period. MagiC can support your control environment; it cannot by itself make your deployment "SOC 2 compliant." Engage a qualified CPA and consult your compliance team before making any claims.
+
+## Purpose
+
+Map MagiC's built-in features to the [AICPA Trust Services Criteria (TSC) 2017, revised 2022](https://www.aicpa-cima.com/topic/audit-assurance/audit-and-assurance-greater-than-soc-2) that underpin SOC 2 Type II. This helps teams:
+
+- Identify which controls MagiC provides out of the box.
+- See which controls are the operator's responsibility (deployment, process, people).
+- Plan the gap analysis before engaging an auditor.
+
+## Scope
+
+- MagiC core server (Go), `core/`.
+- SDKs (Python / Go / TypeScript) are in-scope only when they are part of the product being audited.
+- Workers are third-party systems — audit them separately.
+
+## Trust Services Criteria
+
+SOC 2 Type II covers five TSCs. **Security** is mandatory; the others are optional and selected based on your commitments to customers.
+
+| TSC | MagiC covers it? |
+|-----|------------------|
+| Security (Common Criteria) | Partially — see CC1–CC9 below |
+| Availability | Partially — depends on deployment (HA, backup) |
+| Processing Integrity | Partially — evaluator + audit log |
+| Confidentiality | Partially — RBAC + encryption at rest depends on operator |
+| Privacy | Partially — see [GDPR](gdpr.md); some gaps around consent/notice |
+
+## Common Criteria (Security) Mapping
+
+Below, **control** describes what MagiC provides, and **operator responsibility** describes what the deployment team must add.
+
+### CC6 — Logical and Physical Access Controls
+
+| TSC | MagiC control | Operator responsibility |
+|-----|---------------|-------------------------|
+| **CC6.1** Logical access to information assets | **RBAC** (`core/internal/rbac/`) with three roles: `owner`, `admin`, `viewer`. Role bindings scoped per org. **Policy Engine** (`core/internal/policy/`) blocks disallowed capabilities. | Create role bindings for every org (empty bindings = open access in dev mode). Integrate with IdP via future SSO/OIDC. |
+| **CC6.2** Provisioning and deprovisioning | Worker token issuance via `POST /api/v1/orgs/{orgID}/tokens`; per-org `DELETE /api/v1/orgs/{orgID}/tokens/{id}`. Human subjects via role bindings. | Document joiner/mover/leaver workflow. Rotate tokens when a contractor leaves. |
+| **CC6.3** Access modifications | Audit log records all role and token changes. | Review audit log quarterly. |
+| **CC6.6** Restriction of logical access | Per-endpoint rate limiting; per-org rate limits; SSRF protection on webhook URLs. | Add a WAF (Cloudflare, AWS WAF) in front of the gateway for volumetric protection. |
+| **CC6.7** Identity management | Worker tokens (HMAC-verified `token_hash` column); API keys (32+ bytes enforced). | Store `MAGIC_API_KEY` in a secrets manager (Vault, AWS SM, GCP SM). Never commit. |
+| **CC6.8** System controls for malicious software | Dockerfile runs as non-root; multi-stage build; minimal base image. | Scan images in CI (e.g., Trivy, Grype). Subscribe to security advisories. |
+
+### CC7 — System Operations
+
+| TSC | MagiC control | Operator responsibility |
+|-----|---------------|-------------------------|
+| **CC7.1** Monitoring and logging | Structured JSON logs; Prometheus `/metrics` (14 metrics); audit log API; W3C Trace Context propagation. | Ship logs to a SIEM (Datadog, Elastic, Loki). Alert on error-rate and auth-failure patterns. |
+| **CC7.2** Change management | Git history, semantic versioning, `CHANGELOG.md`, release tags. Migrations via `golang-migrate`. | Enforce PR review, require CI green, tag releases, document rollout in change records. |
+| **CC7.3** Incident detection and response | Event bus publishes `task.failed`, `budget.exceeded`, webhook delivery failures. | Follow the [Incident Response Runbook](../ops/runbook-incident.md); wire events to PagerDuty / Opsgenie. |
+| **CC7.4** Incident response | Runbook templates provided. | Run tabletop exercises quarterly; postmortem every SEV-1/2. |
+| **CC7.5** Recovery | Database migrations reversible (`.down.sql`); backup scripts documented. | Follow the [Backup & Restore](../ops/backup-restore.md) and [DR](../ops/dr.md) guides; run restore drills quarterly. |
+
+### CC8 — Change Management
+
+| TSC | MagiC control | Operator responsibility |
+|-----|---------------|-------------------------|
+| **CC8.1** Change authorization | CODEOWNERS-based review; branch protection on `main`; signed releases (future). | Require 2-person review on main; block direct push; enable branch protection. |
+
+### CC9 — Risk Mitigation
+
+| TSC | MagiC control | Operator responsibility |
+|-----|---------------|-------------------------|
+| **CC9.1** Risk mitigation | Defense-in-depth: API key, RBAC, policy engine, rate limiting, SSRF block, CORS, body size limit. | Threat-model your deployment; document residual risks. |
+| **CC9.2** Vendor management | Sub-processor list (see [GDPR guide](gdpr.md)). `SECURITY.md` discloses scope. | Track vendor SOC 2 reports in your vendor risk register. |
+
+## Availability
+
+| Criterion | MagiC control | Operator responsibility |
+|-----------|---------------|-------------------------|
+| **A1.1** Capacity planning | Prometheus metrics support trend analysis. Cluster mode with PostgreSQL advisory-lock leader election. | Set autoscaling rules, size DB correctly, monitor RPS and tail latency. |
+| **A1.2** Environmental protections | None — MagiC is software only. | Deploy to a cloud provider with data-center controls (SOC 2 attested IaaS). |
+| **A1.3** Recovery | Migration up/down; `pg_dump` / PITR supported. | See [DR guide](../ops/dr.md). Target RTO 1h, RPO 15m (deployment-dependent). |
+
+## Processing Integrity
+
+| Criterion | MagiC control | Operator responsibility |
+|-----------|---------------|-------------------------|
+| **PI1.1** Processing definitions | Task contract enforces timeout, max cost. Evaluator validates outputs against JSON schema. | Define per-task schemas and SLAs. |
+| **PI1.4** Detected errors | DLQ (`GET /api/v1/dlq`), webhook retry with exponential backoff, event bus publishes failures. | Monitor DLQ; investigate sustained failures. |
+| **PI1.5** System inputs and outputs | `request_id` on every request; `trace_id` on every task/workflow. | Retain request/trace IDs in downstream logs for end-to-end correlation. |
+
+## Confidentiality
+
+| Criterion | MagiC control | Operator responsibility |
+|-----------|---------------|-------------------------|
+| **C1.1** Identification | Entities tagged with `org_id` for tenancy isolation. | Enforce tenant boundaries in your client code. |
+| **C1.2** Encryption in transit | Not terminated by MagiC. | Terminate TLS at the proxy / load balancer. Use TLS 1.2+ with modern ciphers. |
+| Encryption at rest | Not built-in. | Enable Postgres TDE or use an encrypted volume. Managed Postgres usually has this on by default. |
+
+## Privacy
+
+See the [GDPR Guide](gdpr.md) for a fuller treatment. Summary:
+
+- MagiC provides audit log, RBAC, and org-scoped storage.
+- Gaps: no built-in export or cascading-delete endpoint yet (see TODOs in GDPR doc).
+- Consent management, notice, and data subject request tracking are operator responsibilities.
+
+## Gap Analysis — Operator Responsibilities
+
+These items are **not** shipped by MagiC and must be designed and operated by the team running it. An auditor will expect evidence for each.
+
+| Area | What you must do |
+|------|------------------|
+| TLS termination | Configure reverse proxy / load balancer with modern TLS. Enforce HSTS. |
+| Encryption at rest | Enable disk / tablespace encryption on Postgres. |
+| Key management | Use a secrets manager for `MAGIC_API_KEY`, worker tokens, webhook secrets, LLM keys. |
+| Backups | Daily full + WAL archiving for PITR. Tested quarterly. |
+| DR drills | Quarterly tabletop, annual full failover. |
+| SIEM / log shipping | Aggregate logs and metrics; alert on anomalies. |
+| Access review | Quarterly review of role bindings + tokens. |
+| Employee onboarding/offboarding | Document the process; integrate with HR. |
+| Vendor risk register | Track sub-processor SOC 2 reports and DPAs. |
+| Security training | Annual training for engineers. |
+| Penetration testing | At least annually; document findings + remediation. |
+
+## Audit Log Retention
+
+SOC 2 baseline guidance for the audit log:
+
+- **Minimum**: 12 months online, easily queryable.
+- **Recommended**: 12 months online + 3 years archived (S3 Glacier, Azure Archive, GCS Archive) for forensic use.
+- Integrity: ship audit log events to an append-only sink (S3 Object Lock, WORM) so an attacker with DB access cannot tamper with history.
+
+MagiC writes audit entries to the `audit_log` table and publishes them to the event bus. Subscribe a webhook to `audit.*` events and forward to your archival sink.
+
+## Recommended Evidence Package
+
+For a SOC 2 Type II audit, collect the following over the observation period:
+
+- Role-binding change history (audit log export).
+- Sample request logs showing request IDs and trace IDs.
+- Backup job logs (success/failure) and at least one restore drill log.
+- Incident runbook entries and postmortems.
+- Change management records (PRs merged, CI green, release tags).
+- Access review reports (quarterly).
+- Vulnerability scan reports and dependency upgrade PRs.
+- Employee onboarding/offboarding tickets.

+# Migrate from v0.8 to v1.0
+
+Guide for upgrading existing MagiC v0.x deployments to v1.0.
+
+**Estimated time: 1-2 hours** depending on deployment size.
+
+---
+
+## Before You Start
+
+This guide is for operators running MagiC v0.8.x or earlier. If you're starting fresh, skip to the quickstart in the main README.
+
+**Who should read this:**
+- Operators with MagiC in production
+- Teams with existing workers deployed
+- Deployments using custom storage (PostgreSQL, SQLite)
+
+---
+
+## Pre-Migration Checklist
+
+Run these checks before touching anything:
+
+- [ ] Read the **Breaking Changes** section below
+- [ ] Read the `CHANGELOG.md` for v1.0.0 release notes
+- [ ] Test in **staging** first (don't jump straight to prod)
+- [ ] Take a fresh database backup:
+  ```bash
+  pg_dump "$MAGIC_POSTGRES_URL" > magic-v0.8-backup.sql
+  ```
+- [ ] Record current schema version:
+  ```bash
+  psql "$MAGIC_POSTGRES_URL" -c "SELECT version FROM schema_migrations ORDER BY version DESC LIMIT 1;"
+  ```
+- [ ] Snapshot Prometheus dashboard (grab error rate, p95 latency, worker count)
+- [ ] Announce maintenance window (internal team + customers if applicable)
+- [ ] Have rollback plan ready (see **Rollback** section)
+
+---
+
+## Breaking Changes Summary
+
+v1.0.0 introduces **3 breaking changes**. Most are minor; one requires action.
+
+### 1. Store Interface: All Methods Take Context
+
+**Impact:** If you use the **Go SDK directly** (not the Python/TypeScript SDK), method signatures changed.
+
+**Before (v0.8):**
+```go
+worker, err := store.GetWorker("worker_123")
+```
+
+**After (v1.0):**
+```go
+worker, err := store.GetWorker(ctx, "worker_123")
+```
+
+**Who is affected:** Custom Go code calling `sdk/go/internal/store/` methods directly.
+
+**Who is NOT affected:** Python SDK users, TypeScript SDK users, REST API users.
+
+**Fix:** Add `context.Background()` or your request context to all store method calls:
+```go
+ctx := context.Background()
+worker, err := store.GetWorker(ctx, "worker_123")
+```
+
+See `sdk/go/examples/` for updated patterns.
+
+### 2. Health Check Response: `version` → `protocol_version`
+
+**Impact:** If you scrape `/health` and parse the response, the field name changed.
+
+**Before (v0.8):**
+```json
+{
+  "status": "ok",
+  "version": "0.8.0"
+}
+```
+
+**After (v1.0):**
+```json
+{
+  "status": "ok",
+  "protocol_version": "1.0",
+  "server_version": "1.0.0"
+}
+```
+
+**Who is affected:** Monitoring scripts, load balancer health checks, custom dashboards parsing `/health`.
+
+**Fix:** Update parsing to use `protocol_version` (for protocol compatibility checks) and `server_version` (for release version):
+```bash
+# Old
+curl http://localhost:8080/health | jq -r .version
+
+# New
+curl http://localhost:8080/health | jq -r .server_version
+```
+
+### 3. Cost Metric Labels: New `org_id` Label
+
+**Impact:** Prometheus metric `magic_cost_total_usd` now has an `org_id` label. Existing dashboards that don't account for labels will show zero.
+
+**Before (v0.8):**
+```
+magic_cost_total_usd 45.67
+```
+
+**After (v1.0):**
+```
+magic_cost_total_usd{org_id="acme"} 30.00
+magic_cost_total_usd{org_id="widgets"} 15.67
+```
+
+**Who is affected:** Grafana dashboards, Prometheus alert rules, custom metric parsers.
+
+**Fix:** Update queries to sum across orgs or select a specific org:
+```promql
+# Old (will show 0 — wrong!)
+magic_cost_total_usd
+
+# New (correct)
+sum(magic_cost_total_usd)
+# or specific org
+magic_cost_total_usd{org_id="acme"}
+```
+
+---
+
+## New Features to Adopt (Optional but Recommended)
+
+v1.0 adds powerful production features. Not required to upgrade, but recommended to enable during the upgrade window.
+
+### OIDC / JWT Authentication
+
+Replace API key with federated identity (Okta, Auth0, Azure AD):
+
+```bash
+# Set these env vars
+export MAGIC_OIDC_ISSUER=https://your-idp.com
+export MAGIC_OIDC_CLIENT_ID=...
+export MAGIC_OIDC_CLIENT_SECRET=...
+```
+
+Workers and clients authenticate via OIDC tokens instead of API keys. Useful for multi-team deployments.
+
+See `docs-site/guide/oidc.md` for setup.
+
+### PostgreSQL Row-Level Security (RLS)
+
+Enforce data isolation at the database layer:
+
+```bash
+export MAGIC_SECRETS_PROVIDER=env  # or vault/ssm/etc
+export MAGIC_DB_ROLE_NAME=magic_app  # non-superuser role
+```
+
+With RLS enabled, each organization's data is automatically filtered by the database. Even a SQL injection in MagiC code can't leak data across orgs.
+
+See `docs-site/guide/rls.md` for implementation.
+
+### Redis Rate Limiting
+
+If running **multiple replicas**, use Redis for distributed rate limiting:
+
+```bash
+export MAGIC_REDIS_URL=redis://redis:6379
+```
+
+Without Redis, each replica has its own rate limit counter (quota per-instance). With Redis, quotas are global across all replicas.
+
+Only needed if: `replicas > 1` or multi-datacenter.
+
+### OpenTelemetry Traces
+
+Export traces to Jaeger, Tempo, or any OTel collector:
+
+```bash
+export OTEL_EXPORTER_OTLP_ENDPOINT=http://otel-collector:4318
+export OTEL_EXPORTER_OTLP_HEADERS=Authorization=Bearer%20token123
+```
+
+You'll see full request tracing from gateway → router → dispatcher → worker.
+
+Optional but highly recommended for production.
+
+### Helm Chart
+
+If running on Kubernetes, v1.0 includes a production-ready Helm chart:
+
+```bash
+helm dependency update deploy/helm/magic/
+helm install magic deploy/helm/magic/ --namespace magic --create-namespace
+```
+
+The chart handles:
+- Rolling updates with zero downtime
+- Pod disruption budgets
+- Prometheus ServiceMonitor
+- PostgreSQL subchart (optional)
+- Network policies
+- Resource limits
+
+See `deploy/README.md` for options.
+
+---
+
+## Step-by-Step Migration
+
+### Step 1: Upgrade the Binary or Image
+
+**Option A: Single instance (systemd)**
+```bash
+# Get new binary
+curl -LO https://github.com/kienbui1995/magic/releases/download/v1.0.0/magic-linux-amd64
+chmod +x magic-linux-amd64
+sudo mv magic-linux-amd64 /usr/local/bin/magic
+
+# Verify
+magic --version
+# Should print: magic version 1.0.0
+```
+
+**Option B: Docker**
+```bash
+# Pull new image
+docker pull kienbui1995/magic:v1.0.0
+
+# Update docker-compose.yml or your deployment
+image: kienbui1995/magic:v1.0.0
+```
+
+**Option C: Kubernetes / Helm**
+```bash
+helm upgrade magic deploy/helm/magic/ \
+  --set image.tag=v1.0.0 \
+  --wait \
+  --timeout 10m
+```
+
+### Step 2: Stop the Old Version
+
+```bash
+# Systemd
+sudo systemctl stop magic
+
+# Docker Compose
+docker compose down
+
+# Kubernetes
+kubectl scale deploy magic --replicas=0 -n magic
+# or: helm upgrade ... --set replicaCount=0
+```
+
+### Step 3: Apply Database Migrations
+
+Migrations run automatically on startup. But you can pre-run them if your policy requires separation:
+
+```bash
+# Check current version
+migrate -database "$MAGIC_POSTGRES_URL" \
+  -path core/internal/store/migrations \
+  version
+
+# Apply latest
+migrate -database "$MAGIC_POSTGRES_URL" \
+  -path core/internal/store/migrations \
+  up
+```
+
+If using Kubernetes, the first pod to start will run migrations (safe with rolling update and additive migrations).
+
+### Step 4: Restart the New Version
+
+```bash
+# Systemd
+sudo systemctl start magic
+journalctl -u magic -f  # watch logs
+
+# Docker Compose
+docker compose up -d
+docker compose logs -f magic
+
+# Kubernetes
+kubectl scale deploy magic --replicas=2 -n magic
+# or: helm upgrade ... --set replicaCount=2
+kubectl -n magic rollout status deploy/magic
+```
+
+Watch for these messages in logs:
+```
+[INFO] Applying migration: ...
+[INFO] Migration 005 completed
+[INFO] Ready
+```
+
+### Step 5: Verify Health
+
+```bash
+# Health check
+curl http://localhost:8080/health
+
+# Should print:
+# {
+#   "status": "ok",
+#   "protocol_version": "1.0",
+#   "server_version": "1.0.0",
+#   "uptime_seconds": 45
+# }
+```
+
+### Step 6: Update Configuration (Optional)
+
+v1.0 introduces optional YAML config files. You can continue using env vars, or migrate to `magic.yaml`:
+
+```yaml
+# magic.yaml
+server:
+  port: 8080
+  cors_origin: https://yourdomain.com
+
+database:
+  postgres_url: postgres://...
+
+auth:
+  api_key: ${MAGIC_API_KEY}  # still from env
+  oidc_issuer: https://your-idp.com  # new optional
+
+storage:
+  backend: postgres
+  pgvector_dim: 1536
+
+observability:
+  otel_endpoint: http://collector:4318
+```
+
+```bash
+# Run with config
+./bin/magic serve --config magic.yaml
+```
+
+Env vars override config file values. You don't need to move everything at once.
+
+### Step 7: Update Monitoring and Dashboards
+
+Fix the three items from **Breaking Changes** above:
+
+1. **Go SDK calls**: Add `ctx` parameter
+2. **Health check parsing**: Use `server_version` instead of `version`
+3. **Prometheus queries**: Add `org_id` label or use `sum()`
+
+### Step 8: Monitor for 24 Hours
+
+Watch these metrics:
+- Error rate (`http_requests_total{status=~"5.."}`)
+- Task success rate (`magic_tasks_completed_total / (magic_tasks_completed_total + magic_tasks_failed_total)`)
+- Worker count (`magic_workers_online`)
+- P95 latency (histogram: `http_requests_duration_seconds`)
+- Webhook delivery queue depth (`magic_webhook_pending_deliveries`)
+
+No spikes? Good. Stay in this state for at least 1 business day before decommissioning the old version.
+
+---
+
+## Zero-Downtime Deployment (Kubernetes)
+
+If running on Kubernetes with PostgreSQL backend:
+
+1. Database migrations are **additive only** in v1.0 (no destructive drops)
+2. Enable rolling updates:
+   ```bash
+   helm upgrade magic deploy/helm/magic/ \
+     --set image.tag=v1.0.0 \
+     --set replicaCount=2 \  # minimum 2
+     --set podDisruptionBudget.enabled=true \
+     --wait \
+     --timeout 15m
+   ```
+3. Watch rollout: `kubectl rollout status deploy/magic -n magic`
+4. First pod starts, runs migrations, comes online. Other pods serve traffic. Second pod starts. Traffic transitions.
+
+**Downtime: ~0 seconds** (assuming your client retries on 503).
+
+---
+
+## Rollback Procedure
+
+If something goes wrong after upgrade:
+
+### Option 1: No Schema Changes (Fastest)
+
+If you didn't run migrations or only used additive ones (v1.0 default):
+
+```bash
+# Rollback deployment
+helm rollback magic <previous-revision> -n magic
+# or: change docker image tag, restart
+
+# Old version starts up and reads current schema
+# (it's compatible with both old and new code)
+```
+
+Done. Zero data loss.
+
+### Option 2: Schema Rollback (Requires Restore)
+
+If a migration broke something unexpectedly:
+
+```bash
+# 1. Stop new version
+helm upgrade magic deploy/helm/magic/ --set replicaCount=0 -n magic
+
+# 2. Restore backup
+psql "$MAGIC_POSTGRES_URL" < magic-v0.8-backup.sql
+
+# 3. Start old version
+helm rollback magic <previous-revision> -n magic
+kubectl rollout status deploy/magic -n magic
+```
+
+**You lose data between backup and rollback.** That's why backups are critical.
+
+---
+
+## Version Skew Tolerance
+
+v1.0 server is compatible with v0.x clients (SDKs) **within the same MAJOR version**.
+
+- **v1.0 server + v0.8 Python SDK**: Works (SDK is HTTP-based, doesn't care about internal Go changes)
+- **v1.0 server + v0.8 Go SDK**: **Broken** (Go SDK imports store directly, method signatures changed)
+- **v0.8 server + v1.0 Python SDK**: Works (newer client talks to older server via REST)
+
+**Recommendation:** Upgrade SDKs after the server is stable (next day or week). Pin SDK versions in your apps.
+
+---
+
+## FAQ
+
+**Q: Can I skip v0.9 and go straight to v1.0?**
+A: Yes. v1.0 is backward compatible with v0.8 (migrations are additive). v0.9 doesn't exist; v0.8 → v1.0 is the path.
+
+**Q: How long does the migration take?**
+A: For in-memory (no persistence): 30 seconds. For PostgreSQL: depends on schema size (usually < 5 minutes for tables < 1GB).
+
+**Q: Do workers need to be restarted?**
+A: No. Workers keep their tokens and reconnect fine. No breaking changes to the worker protocol.
+
+**Q: What if the migration fails partway?**
+A: Stop MagiC, restore the backup, start v0.8 again. No partial state is left behind.
+
+**Q: Can I run v0.8 and v1.0 side by side?**
+A: Only with different databases. Sharing a database: not recommended (migrations will conflict).
+
+**Q: Is there a YAML migration tool?**
+A: Not yet. Edit env vars → YAML by hand. Usually 5 minutes for a production config.

+# Backup and Restore
+
+This guide covers operational backup and restore for a MagiC deployment running against PostgreSQL. SQLite deployments use the same principles — substitute a file-copy strategy.
+
+MagiC has **no internal backup mechanism**. All persistence is in Postgres, and backup is a database-layer concern. This is intentional: Postgres-native tooling is battle-tested and your cloud provider already offers it.
+
+## What to Back Up
+
+| Artifact | Location | Backup? | Why |
+|----------|----------|---------|-----|
+| PostgreSQL data | `$MAGIC_POSTGRES_URL` database | **Yes** | All entities — workers, tasks, workflows, teams, knowledge, audit log, webhooks, tokens, DLQ, prompts, memory, costs. |
+| `pg_vector` extension data | Same DB | **Yes** | Embeddings live in the `knowledge_embeddings` table. |
+| Server config | env vars, `magic.yaml` | Version-control | `magic.yaml` belongs in git. Secrets go in your secrets manager. |
+| `MAGIC_API_KEY`, worker tokens, webhook secrets, LLM keys | Secrets manager | Yes (by the secrets manager) | Rotate and back up per your KMS / SM policy. |
+| Binaries / Docker images | Registry | Registry retention | Re-deploy from tag rather than backup. |
+| Logs / metrics | Log store / Prometheus | Per your SIEM retention | Not part of DR path but needed for forensics. |
+| Prometheus TSDB | Ephemeral | No | Scrape again after recovery; do not back up time-series. |
+
+## Backup Methods (Postgres)
+
+Pick one **primary** method based on RPO and scale. Most teams combine (a) managed snapshots + (b) WAL archiving for PITR.
+
+### A. `pg_dump` (logical backup)
+
+```bash
+# Full dump of the MagiC database
+pg_dump \
+  --host="$PGHOST" \
+  --username="$PGUSER" \
+  --format=custom \
+  --compress=9 \
+  --file="magic-$(date -u +%Y%m%dT%H%M%SZ).dump" \
+  magic
+
+# Schema-only dump (for disaster-recovery smoke tests)
+pg_dump --schema-only --format=plain --file=magic-schema.sql magic
+```
+
+- Pros: portable, easy to test, easy to filter.
+- Cons: Snapshot-in-time only; not suitable for high-RPO requirements. Downtime or lock pressure on very large DBs.
+
+### B. Continuous archiving + PITR
+
+Point-in-time recovery with WAL archiving is the gold standard for production.
+
+Key settings in `postgresql.conf`:
+
+```conf
+wal_level           = replica
+archive_mode        = on
+archive_command     = 'aws s3 cp %p s3://<bucket>/wal/%f'  # or equivalent
+archive_timeout     = 60   # seconds — caps RPO
+max_wal_senders     = 10
+```
+
+Take a base backup with `pg_basebackup`:
+
+```bash
+pg_basebackup \
+  --host="$PGHOST" \
+  --username=replicator \
+  --pgdata=/backups/base-$(date -u +%Y%m%d) \
+  --format=tar \
+  --gzip \
+  --wal-method=stream \
+  --checkpoint=fast
+```
+
+- Pros: restore to any transaction in the archived window.
+- Cons: more moving parts; test end-to-end quarterly.
+
+### C. Managed database snapshots
+
+If you use AWS RDS / Aurora, GCP Cloud SQL, Azure DB for Postgres, Supabase, Neon, or similar — **use the provider's snapshot + PITR feature.**
+
+- AWS RDS: automated backups with 1-35 day retention + manual snapshots.
+- GCP Cloud SQL: automated backups + binary log PITR.
+- Azure DB for Postgres: automatic geo-redundant backups.
+- Neon / Supabase / Crunchy Bridge: built-in PITR.
+
+Delegating to the managed provider removes most of the operational burden. **Verify** that snapshots are encrypted and that the provider holds a SOC 2 / HIPAA BAA if required.
+
+## Retention Policy
+
+Default recommendation for production:
+
+| Tier | Frequency | Retain | Storage class |
+|------|-----------|--------|---------------|
+| WAL / PITR window | Continuous | 7-14 days | Hot |
+| Daily full | Daily | 7 dailies | Warm |
+| Weekly full | Weekly | 4 weeklies | Warm |
+| Monthly full | Monthly | 12 monthlies | Cold (Glacier / Archive / Coldline) |
+| Annual full | Yearly | 7 years (or per your retention policy) | Cold |
+
+Tune to your RPO target and your regulatory obligations. HIPAA demands 6 years of documentation; GDPR demands retention to be no longer than necessary — balance.
+
+## Encryption and Access Control
+
+- Encrypt backups at rest. S3 with SSE-KMS, GCS with CMEK, Azure Blob with CMK.
+- Use a **different** key for backup storage than for the live DB so a compromised DB key does not unlock backups.
+- Restrict IAM to backup-writer and restore-reader roles. No human should have read access to all backups; require a break-glass review.
+- Keep backup bucket versioning + MFA Delete enabled for immutability.
+
+## Restore — Step by Step
+
+Restore is a **drill-until-boring** procedure. Do it on a non-prod cluster first, always.
+
+### Scenario 1 — Restore latest `pg_dump`
+
+```bash
+# 1. Spin up target Postgres (empty). Let MagiC run migrations first.
+./magic serve & sleep 5 && kill %1
+# (MagiC runs golang-migrate on startup, creating tables.)
+
+# 2. Or restore the dump directly, which creates tables:
+pg_restore \
+  --host="$PGHOST" \
+  --username="$PGUSER" \
+  --dbname=magic \
+  --clean --if-exists \
+  --no-owner --no-privileges \
+  --jobs=4 \
+  magic-20260418T120000Z.dump
+
+# 3. Verify row counts against the source.
+psql -c "SELECT 'workers' t, COUNT(*) FROM workers
+         UNION ALL SELECT 'tasks', COUNT(*) FROM tasks
+         UNION ALL SELECT 'audit_log', COUNT(*) FROM audit_log;"
+
+# 4. Start MagiC.
+./magic serve
+```
+
+### Scenario 2 — PITR to specific timestamp
+
+Using standard Postgres recovery; steps vary by managed provider. Generalized:
+
+```bash
+# 1. Stop traffic to the primary (if still reachable). Put MagiC in maintenance.
+
+# 2. Take down the primary; bring up a recovery cluster from the base backup.
+tar -xzf base-20260418.tar.gz -C /var/lib/postgresql/data
+
+# 3. Configure recovery:
+cat > /var/lib/postgresql/data/recovery.signal <<'EOF'
+EOF
+cat >> /var/lib/postgresql/data/postgresql.conf <<'EOF'
+restore_command = 'aws s3 cp s3://<bucket>/wal/%f %p'
+recovery_target_time = '2026-04-18 14:32:00+00'
+recovery_target_action = 'promote'
+EOF
+
+# 4. Start Postgres; it will replay WAL up to the target and promote.
+systemctl start postgresql
+
+# 5. Smoke test: connect, count rows, hit /health.
+curl http://localhost:8080/health
+
+# 6. Point MAGIC_POSTGRES_URL at the restored instance and restart MagiC.
+```
+
+### Scenario 3 — Managed provider snapshot restore
+
+```bash
+# AWS RDS example
+aws rds restore-db-instance-from-db-snapshot \
+  --db-instance-identifier magic-restored \
+  --db-snapshot-identifier magic-2026-04-18-1200 \
+  --db-subnet-group-name magic-private
+
+# GCP Cloud SQL example
+gcloud sql backups restore BACKUP_ID \
+  --restore-instance=magic-primary \
+  --backup-instance=magic-primary
+```
+
+Always restore to a **new** instance name, validate, then swap traffic. Never overwrite the primary until you are certain.
+
+## Post-Restore Checklist
+
+- [ ] `curl /health` returns healthy.
+- [ ] `curl /metrics` exports metrics.
+- [ ] Audit log query returns recent entries.
+- [ ] A tasks query returns expected count (compare to backup metadata).
+- [ ] Worker registration works.
+- [ ] A canary task round-trips end-to-end.
+- [ ] Webhook deliveries resume (check `webhook_deliveries` with `status = 'pending'`).
+- [ ] Rotate any credentials that may have leaked during the incident.
+- [ ] Update the status page + postmortem with the timeline.
+
+## Testing — Restore Drills
+
+**Untested backups are wishes, not backups.**
+
+- **Quarterly:** restore the latest daily dump to a staging DB. Run the smoke test. Record the elapsed time — this is your **actual** RTO for this scenario.
+- **Annually:** full DR drill — simulated region loss, restore from cold storage, run the app against it, have a customer-facing team run through their workflow.
+- Log every drill with: scenario, steps executed, deltas from plan, elapsed time. Publish to the maintainers channel.
+
+If a drill uncovers a gap (e.g., a new table missing from your logical backup filter), update the runbook **immediately**.
+
+## Cross-Region Replication
+
+For multi-region DR:
+
+- **Streaming replication** — Postgres streaming to a warm standby in another region. Lag is typically <1 s; RPO ≈ replication lag.
+- **Logical replication** — per-table replication; flexible but more operationally heavy.
+- **Managed providers** — AWS RDS read replicas, Aurora Global Database; GCP Cloud SQL cross-region replicas; Azure DB for Postgres cross-region read replicas.
+
+Promotion to writer is a DR decision, not an incident response one. See the [Disaster Recovery guide](dr.md).
+
+## Schema Migrations
+
+MagiC uses [`golang-migrate`](https://github.com/golang-migrate/migrate). Migrations live in `core/internal/store/migrations/`. On startup, MagiC runs `migrate up` automatically.
+
+For restore into a version older than current:
+
+```bash
+# Check current migration version
+migrate -database "$MAGIC_POSTGRES_URL" -path core/internal/store/migrations version
+
+# Forward migrate after restoring an older dump
+migrate -database "$MAGIC_POSTGRES_URL" -path core/internal/store/migrations up
+
+# Roll back one migration (DANGEROUS — only with a confirmed backup)
+migrate -database "$MAGIC_POSTGRES_URL" -path core/internal/store/migrations down 1
+```
+
+For version-skew during upgrade, see the [Upgrade Path guide](upgrade-path.md).

+# Disaster Recovery
+
+This guide describes the MagiC disaster recovery (DR) playbook: targets, scenarios, and procedures for restoring service after a significant failure.
+
+"Disaster" here means events larger than a single-pod restart — database loss, region outage, corrupted state, compromise requiring rebuild.
+
+## RTO and RPO Targets
+
+These are **recommended defaults** for a production deployment. Your contracts and regulatory constraints may require tighter numbers.
+
+| Metric | Target | What it means |
+|--------|--------|---------------|
+| **RTO** (Recovery Time Objective) | **1 hour** | Time from disaster declaration to service restored. |
+| **RPO** (Recovery Point Objective) | **15 minutes** | Maximum tolerable data loss measured in wall-clock time. |
+
+Achieving these requires:
+
+- WAL archiving with `archive_timeout ≤ 60s` **or** streaming replication.
+- Backups tested quarterly (see [Backup & Restore](backup-restore.md)).
+- A warm standby in a second region, or managed geo-redundancy.
+- An incident runbook people have practiced (see [Incident Runbook](runbook-incident.md)).
+
+If your actual RTO/RPO are looser, **publish them to customers** — don't pretend.
+
+## Architecture for DR
+
+Recommended pattern for multi-region DR:
+
+```
+      Region A (primary)                 Region B (standby)
+  ┌────────────────────────────┐      ┌────────────────────────────┐
+  │ MagiC pods (active)        │      │ MagiC pods (scaled to 0    │
+  │   ↕ Cloudflare / LB        │      │ or warm, cluster-mode)     │
+  │ Postgres primary           │ ───► │ Postgres read replica      │
+  │   ↕ WAL stream             │      │   ↕ can be promoted        │
+  │ pgvector                   │      │ pgvector                   │
+  │ Object store (backups)     │ ───► │ Object store (replicated)  │
+  └────────────────────────────┘      └────────────────────────────┘
+             │                                        ▲
+             └──── DNS / Anycast failover ────────────┘
+```
+
+Key properties:
+
+- Postgres primary in Region A, streaming to replica in Region B.
+- Backups (dumps + WAL) replicated to Region B object storage.
+- MagiC pods in Region B can start quickly — image pulled, config ready.
+- DNS TTL ≤ 60s on the service hostname so failover propagates fast.
+- Cloudflare (if used) can geo-route or hard-fail between origins.
+
+For lower-cost setups, skip Region B and rely on same-region multi-AZ + a tested restore from backup. Your RTO and RPO numbers go up accordingly — document the tradeoff.
+
+## DR Scenarios
+
+### Scenario 1: Single pod or instance failure
+
+**Impact:** one MagiC process dies.
+
+**Detection:** Prometheus alert on pod restart / health check failure; Kubernetes events.
+
+**Response:** automatic — Kubernetes restarts via liveness probe; leader election (Postgres advisory lock) reassigns cluster-mode tasks to a live pod.
+
+**Manual action:** none, unless restarts are repeated; investigate the cause per the [Incident Runbook](runbook-incident.md).
+
+**RTO:** seconds. **RPO:** zero.
+
+### Scenario 2: All MagiC pods down (config issue, bad release)
+
+**Impact:** API returns 5xx / unreachable.
+
+**Detection:** health check failure + absence of `/metrics` scrape.
+
+**Response:**
+
+1. Declare SEV-1/2 (see [Incident Runbook](runbook-incident.md)).
+2. Roll back the release — see [Upgrade Path](upgrade-path.md#rollback).
+3. If rollback doesn't help, restore the previous image/binary manually.
+
+**RTO:** 5-15 minutes. **RPO:** zero (DB unaffected).
+
+### Scenario 3: Database failure
+
+**Impact:** MagiC can read env but Postgres is unreachable or corrupt.
+
+**Detection:** connection errors in logs; `magic_db_errors_total` metric; failed `/health` if DB health is part of readiness.
+
+**Response:**
+
+- **Replica available?** Promote the read replica:
+  ```bash
+  # Managed Postgres — use provider failover API
+  aws rds promote-read-replica --db-instance-identifier magic-replica
+  # or
+  gcloud sql instances promote-replica magic-replica
+
+  # Self-hosted
+  pg_ctl promote -D /var/lib/postgresql/data
+  ```
+- Update `MAGIC_POSTGRES_URL` to point at the promoted instance; restart MagiC pods.
+- Verify `/health`.
+
+- **No replica, corruption only?** Restore from latest backup — see [Backup & Restore](backup-restore.md) — accept the RPO gap.
+
+**RTO:** 10-30 minutes with a replica; 1+ hour from backup. **RPO:** streaming lag (typically <5s) with a replica; hours with backup-only.
+
+### Scenario 4: Region failure
+
+**Impact:** entire region unreachable — network, power, or hyperscaler outage.
+
+**Detection:** multi-AZ alerts; external synthetic monitor failure.
+
+**Response:**
+
+1. Declare SEV-1.
+2. Promote the Postgres replica in Region B.
+3. Scale MagiC in Region B from 0 → target replicas (or start cold if warm wasn't maintained).
+4. Update DNS to point the service hostname at Region B's load balancer.
+5. Unregister workers that cannot reach the new region; re-register from their new homes. Worker auto-discovery helps for on-site workers.
+6. Monitor until stable, then post customer communications per the [Incident Runbook](runbook-incident.md).
+
+**RTO:** 30-60 minutes for warm standby; several hours for cold. **RPO:** seconds with streaming; longer without.
+
+### Scenario 5: Data corruption (human error, bad migration, ransomware)
+
+**Impact:** DB is running but data is wrong.
+
+**Detection:** customer reports; integrity checks fail; audit log shows unauthorized changes.
+
+**Response:**
+
+1. **Freeze writes** — put MagiC into maintenance (stop ingress or scale to 0). Do this immediately; every second of writes narrows your PITR options.
+2. Identify the corruption window — when did bad data appear? Audit log is your friend.
+3. Restore to a **point-in-time before corruption** on a separate cluster — see [Backup & Restore Scenario 2](backup-restore.md#scenario-2--pitr-to-specific-timestamp).
+4. Compare — diff interesting tables between the restored copy and the live DB.
+5. Either swap traffic to the restored copy, or cherry-pick corrected rows back into the live DB. The safer choice is swap.
+6. Investigate root cause before re-opening writes.
+
+**RTO:** several hours. **RPO:** bounded by when the bad event started.
+
+If corruption was caused by a compromise (ransomware, malicious insider), treat it as a **security incident** first. See [SECURITY.md](../../SECURITY.md) and consider regulatory notification under GDPR / HIPAA.
+
+### Scenario 6: Compromised credentials
+
+**Impact:** API keys, worker tokens, or webhook secrets leaked.
+
+**Detection:** unusual traffic patterns; notifications from secret-scanning services; customer report.
+
+**Response:**
+
+1. Rotate `MAGIC_API_KEY`. This invalidates all clients — coordinate with API users.
+2. Revoke affected worker tokens: `DELETE /api/v1/orgs/{orgID}/tokens/{id}`.
+3. Rotate webhook secrets; affected customers must reconfigure their receivers.
+4. Rotate LLM provider keys.
+5. Audit the audit log for any actions taken with the compromised credentials since the suspected leak.
+6. File a postmortem; notify customers if their tenants were affected.
+
+**RTO:** 1-4 hours (including client coordination). **RPO:** N/A (data integrity not at stake unless the attacker made writes).
+
+## DR Testing
+
+A DR plan that hasn't been tested is a plan that will fail.
+
+| Cadence | Exercise |
+|---------|----------|
+| **Quarterly — tabletop** | Walk through one of the scenarios above on paper. 60 minutes. Find gaps. |
+| **Quarterly — live restore** | Restore the latest backup to a staging DB. Run smoke tests. Measure actual time. |
+| **Annually — full failover drill** | Promote the standby, swap DNS, run the service on the standby for at least 30 minutes. Optionally fail back. |
+| **After any incident** | Add the scenario to the next tabletop's rotation if it surfaced a gap. |
+
+Document every drill with: date, participants, scenario, actual RTO, deviations from plan, follow-ups.
+
+## Contact Tree
+
+Every deployment should maintain a contact tree in a known, accessible place (Notion, GitHub Wiki, printed binder, or equivalent). Template:
+
+| Role | Primary | Backup | Phone / Pager | Hours |
+|------|---------|--------|----------------|-------|
+| Incident Commander | TBD | TBD | TBD | 24/7 rotation |
+| Database on-call | TBD | TBD | TBD | 24/7 rotation |
+| Cloud infra on-call | TBD | TBD | TBD | 24/7 rotation |
+| Executive sponsor | TBD | TBD | TBD | Business hours + SEV-1 |
+| Legal counsel | TBD | TBD | TBD | Business hours |
+| Communications lead | TBD | TBD | TBD | SEV-1 only |
+| Cloud provider support | Per contract | Per contract | Per contract | Per contract |
+| LLM provider support | Per contract | Per contract | Per contract | Per contract |
+| Managed Postgres support | Per contract | Per contract | Per contract | Per contract |
+
+**TODO: populate this table with real names and numbers for your org before publishing this doc internally.**
+
+## Data Residency Considerations
+
+If you are subject to GDPR, HIPAA, or a contractual data-residency clause, your DR plan **must** respect data location. Pitfalls:
+
+- Object storage backups default to region A but replicate globally — configure explicit regional replication targets.
+- Managed Postgres "cross-region read replicas" may cross the boundary you promised customers — verify the replica region.
+- "Failover to a different region" might breach data residency — have a contingency that stays within the permitted geography (e.g., multi-AZ same region rather than multi-region).
+
+See [GDPR](../compliance/gdpr.md) and [HIPAA](../compliance/hipaa.md) for more.

+# OpenTelemetry Tracing
+
+MagiC emits OTLP-compatible traces. Any OTel collector can ingest them —
+Jaeger, Grafana Tempo, Datadog Agent, Honeycomb, New Relic, AWS X-Ray
+(via ADOT), etc.
+
+When `OTEL_EXPORTER_OTLP_ENDPOINT` is unset MagiC installs a no-op tracer:
+spans cost ~nothing and no network I/O happens. This is the safe default
+for dev.
+
+## Environment variables
+
+| Variable | Purpose | Default |
+|----------|---------|---------|
+| `OTEL_EXPORTER_OTLP_ENDPOINT` | Collector URL, e.g. `http://localhost:4318` | unset (no-op) |
+| `OTEL_EXPORTER_OTLP_PROTOCOL` | `http/protobuf` or `grpc` | `http/protobuf` |
+| `OTEL_SERVICE_NAME` | Service name attached to every span | `magic` |
+| `OTEL_SERVICE_VERSION` | Version tag | unset |
+| `OTEL_TRACES_SAMPLER` | `always_on`, `always_off`, `traceidratio`, `parentbased_traceidratio`, `parentbased_always_on/off` | `always_on` |
+| `OTEL_TRACES_SAMPLER_ARG` | Ratio for ratio-based samplers (0.0–1.0) | `1.0` |
+| `OTEL_RESOURCE_ATTRIBUTES` | Extra resource key-values, e.g. `env=prod,region=ap-se-1` | unset |
+| `MAGIC_OTEL_STDOUT` | `1` to also dump spans to stdout for debugging | off |
+
+## Quickstart — Jaeger (local)
+
+```bash
+docker compose -f deploy/docker-compose.observability.yml up -d
+# MagiC exports to jaeger:4318 automatically (see compose file).
+# Open http://localhost:16686 and search for service "magic".
+```
+
+Submit a task, then view the trace in Jaeger. You will see:
+
+- `POST /api/v1/tasks` — root HTTP span (from `otelhttp` middleware)
+- `dispatcher.Dispatch` — child span with `task.id`, `worker.id` attributes
+- Downstream worker spans — automatically linked via W3C `traceparent`
+  injected by the dispatcher.
+
+## Vendor recipes
+
+### Datadog Agent
+
+Run the Datadog Agent with OTLP enabled and point MagiC at it:
+
+```bash
+OTEL_EXPORTER_OTLP_ENDPOINT=http://dd-agent:4318 \
+OTEL_EXPORTER_OTLP_PROTOCOL=http/protobuf \
+OTEL_SERVICE_NAME=magic \
+OTEL_RESOURCE_ATTRIBUTES="deployment.environment=prod" \
+./magic serve
+```
+
+### Honeycomb
+
+Honeycomb accepts OTLP directly. Supply API key as a header via the standard
+`OTEL_EXPORTER_OTLP_HEADERS` env var:
+
+```bash
+OTEL_EXPORTER_OTLP_ENDPOINT=https://api.honeycomb.io \
+OTEL_EXPORTER_OTLP_HEADERS="x-honeycomb-team=YOUR_API_KEY" \
+OTEL_SERVICE_NAME=magic \
+./magic serve
+```
+
+### Grafana Tempo
+
+Tempo ships with an OTLP receiver. Point at the receiver port:
+
+```bash
+OTEL_EXPORTER_OTLP_ENDPOINT=http://tempo:4318 \
+./magic serve
+```
+
+### New Relic
+
+```bash
+OTEL_EXPORTER_OTLP_ENDPOINT=https://otlp.nr-data.net \
+OTEL_EXPORTER_OTLP_HEADERS="api-key=YOUR_LICENSE_KEY" \
+./magic serve
+```
+
+## Sampling strategy
+
+- **Dev / low traffic**: `always_on` — see every request.
+- **Staging**: `parentbased_traceidratio` with `OTEL_TRACES_SAMPLER_ARG=0.5`
+  so sampled incoming requests stay sampled throughout the pipeline.
+- **Prod / high traffic**: `parentbased_traceidratio` with `0.05`–`0.1`
+  typically balances cost vs signal. For head-based sampling this means
+  5–10% of traces are retained end-to-end.
+- **Debugging a specific tenant**: keep the service on a low ratio but
+  configure the collector (e.g. OTel Collector tail sampler) to retain
+  100% of spans matching `org.id == "tenant-X"`.
+
+## Tuning the batch span processor
+
+Defaults in `core/internal/tracing/init.go`:
+
+- Batch timeout: 5 s
+- Max export batch size: 512 spans
+- Max queue size: 2048 spans
+
+If you see `OTel SDK: span queue full` warnings, raise queue size or
+shorten the batch timeout. If exports are slow / collector flaky, keep
+the queue generous — the processor drops spans silently when full, it
+never blocks hot paths.
+
+## Verification checklist
+
+```bash
+# 1. Tracer installed?
+curl -s http://localhost:8080/health
+# 2. Send a request.
+curl -s -H "Authorization: Bearer $MAGIC_API_KEY" \
+  -H "Content-Type: application/json" \
+  -d '{"type":"echo","input":{"msg":"hi"}}' \
+  http://localhost:8080/api/v1/tasks
+# 3. Open http://localhost:16686 → Service: magic → Find Traces.
+#    You should see "POST /api/v1/tasks" with child span "dispatcher.Dispatch".
+```
+
+## Worker-to-gateway continuity
+
+Workers that use the MagiC Python SDK inherit trace context automatically
+via the `traceparent` header on the outbound `task.assign` HTTP call.
+Legacy workers that only read `X-Trace-ID` keep working — MagiC always
+sets both headers on outbound dispatches.

+# Rate Limiting
+
+MagiC protects the gateway with per-endpoint, per-key token-bucket limits. Two
+backends ship in the binary and are selected at startup by a single env var.
+
+## Backends
+
+| Backend    | How to enable            | Scope               | When to use              |
+|------------|--------------------------|---------------------|--------------------------|
+| In-memory  | (default, no config)     | Per gateway process | Single-instance deploys  |
+| Redis      | Set `MAGIC_REDIS_URL`    | Shared across pods  | Multi-instance deploys   |
+
+**In-memory** uses `golang.org/x/time/rate` with an LRU-style cap of 10,000
+tracked keys per bucket. It is fast and has zero extra infra, but each gateway
+replica counts independently. Running N replicas effectively gives users Nx
+their intended limit — unacceptable for any serious multi-instance deployment.
+
+**Redis** stores each token bucket as a hash under
+`magic:ratelimit:{bucket}:{key}` and refills/consumes atomically via a Lua
+script. All replicas share the same counters, so a user hits the real limit
+regardless of which instance handled the request.
+
+## Enabling Redis
+
+```bash
+# Standard redis URL; username/password optional.
+export MAGIC_REDIS_URL="redis://redis.internal:6379/0"
+
+# TLS / Redis Cloud / Upstash also work:
+export MAGIC_REDIS_URL="rediss://user:pass@example.upstash.io:6379"
+```
+
+MagiC logs the choice at startup:
+
+```
+rate limiter: redis (addr=redis.internal:6379)
+```
+
+or, when unset:
+
+```
+rate limiter: in-memory (set MAGIC_REDIS_URL for distributed limiting)
+```
+
+No other env vars are needed; existing per-endpoint rates are unchanged.
+
+## Fail-open policy
+
+If Redis is unreachable or returns an error, the Redis limiter **allows the
+request** and logs a warning (rate-limited to ~1 line per 5s per bucket to
+avoid log floods). We explicitly prefer letting traffic through over
+rejecting valid users because of infra issues — rate limits are a guardrail,
+not a primary security control.
+
+Operators should monitor Redis separately (health check, `PING`, Prometheus
+redis_exporter) and alert on `magic_rate_limit_hits_total` dropping to zero
+unexpectedly, which can indicate the limiter has degraded to fail-open.
+
+## Default rate limits
+
+These are set in `core/internal/gateway/gateway.go` and apply to both backends.
+
+| Endpoint group                                   | Bucket name | Rate               | Burst | Key         |
+|--------------------------------------------------|-------------|--------------------|-------|-------------|
+| `POST /api/v1/workers/register`                  | `register`  | 10 req/IP/min      | 5     | client IP   |
+| `POST /api/v1/workers/heartbeat`                 | `heartbeat` | 4 req/IP/min       | 4     | client IP   |
+| `POST/DELETE /api/v1/orgs/{orgID}/tokens/*`      | `token`     | 20 req/org/min     | 10    | orgID       |
+| `POST /api/v1/tasks` (and `/tasks/stream`) — IP  | `task`      | 200 req/IP/min     | 20    | client IP   |
+| `POST /api/v1/tasks` (and `/tasks/stream`) — org | `orgtask`   | 200 req/org/min    | 20    | X-Org-ID    |
+| `POST /api/v1/llm/chat`, prompts, memory writes  | `llm`       | 30 req/IP/min      | 5     | client IP   |
+
+`client IP` honours `X-Forwarded-For` only when `MAGIC_TRUSTED_PROXY=true`
+(see `ratelimit.go::clientIP`).
+
+## Disabling for local dev / load tests
+
+```bash
+MAGIC_RATE_LIMIT_DISABLE=true ./magic serve
+```
+
+This short-circuits the middleware entirely; no key lookups, no Redis calls.
+
+## Monitoring
+
+Exposed on `/metrics` (Prometheus):
+
+```
+magic_rate_limit_hits_total{path="/api/v1/workers/register"}  counter
+```
+
+Incremented every time a request is denied (429). Sudden spikes usually mean
+either a real abuse wave or an integration bug in a client worker.
+
+## When should I upgrade to Redis?
+
+- You run ≥2 gateway replicas → **yes, always**.
+- You plan to autoscale → **yes**, or rate limits become meaningless under scale.
+- Single instance, dev / staging → in-memory is fine.
+
+The switch is a single env var and a small Redis (even 128 MB is plenty — the
+bucket keys are tiny hashes and auto-expire after 10 minutes of idle).

+# Incident Response Runbook
+
+This runbook is the default response playbook for operational incidents in a MagiC deployment. Adapt it to your organization — severity thresholds, on-call tooling, and communication channels vary.
+
+## Goals
+
+1. Stop the bleeding — restore service faster than investigating root cause.
+2. Communicate clearly — internal team, customers, and (if needed) regulators.
+3. Learn — blameless postmortem, actionable follow-ups.
+
+## Severity Levels
+
+| Severity | Definition | Examples | Response time | Paging |
+|----------|------------|----------|---------------|--------|
+| **SEV-1** | Core service down for multiple customers; data loss; active security incident; regulatory breach. | API returning 5xx for >5 min; data corruption confirmed; suspected active intrusion; PHI/PII exposed. | Immediate. All hands. | Page on-call + tech lead + leadership. |
+| **SEV-2** | Partial outage; significant degradation; single-customer impact on a critical path; degraded security posture. | Workflow execution stalled; DLQ growing; auth failing for one org; webhook deliveries failing for one customer. | 30 min to engage. Business hours primary. | Page on-call. |
+| **SEV-3** | Minor degradation; cosmetic; workaround available. | Single worker offline with automatic failover; noisy metric; docs broken. | Next business day. | Ticket + #ops channel. |
+| **SEV-4** | Informational — not an incident. | Planned maintenance, release notification. | Scheduled. | Announcement only. |
+
+When in doubt, **overcall** the severity. It's cheaper to step down than to step up late.
+
+## Escalation Path
+
+```
+  On-call engineer (primary)
+           │
+           │ (acknowledge within 5 min for SEV-1, 15 min for SEV-2)
+           ▼
+  Tech lead / module owner (see MAINTAINERS.md)
+           │
+           │ (for SEV-1 that lasts >30 min without a mitigation path)
+           ▼
+  Executive / delegated owner (CTO, VP Eng, founder)
+           │
+           │ (for customer-impacting SEV-1 or regulatory exposure)
+           ▼
+  Legal + Communications
+```
+
+Record every handoff in the incident channel with timestamp and decision.
+
+## During the Incident — Commander's Checklist
+
+The **Incident Commander (IC)** owns the response, not the investigation. For small teams the on-call engineer may be both.
+
+1. [ ] Open an incident channel (Slack `#inc-<short-name>` or equivalent).
+2. [ ] Declare the severity. Post it at the top of the channel and pin.
+3. [ ] Acknowledge the pager. Silence duplicate alerts.
+4. [ ] Identify the scope: which customers, which modules, since when.
+5. [ ] Publish the first internal update within 10 minutes.
+6. [ ] For customer-impacting SEV-1/2: update the public status page.
+7. [ ] Keep the channel narrated — every action, every finding, with timestamp.
+8. [ ] Rotate if the incident crosses 4 hours. Fatigue causes more incidents.
+9. [ ] Declare resolved only after: metrics green for 15 min, customers notified, workaround removed or documented.
+
+### Immediate Mitigation Playbook
+
+Try these in order when symptoms point to MagiC itself:
+
+- **API returning 5xx** — check `/metrics` (`magic_http_requests_total` by status), logs, Postgres health. Consider rolling back the most recent deployment.
+- **DLQ growing** — see [`GET /api/v1/dlq`](../../README.md). Pause the affected worker, investigate the common error pattern, drain or purge once fixed.
+- **Auth failures spiking** — check `audit.denied` events. Could be rotation of `MAGIC_API_KEY` without propagation, or brute-force attempt — engage security.
+- **Workers heartbeat failing** — check network path to workers. Registry marks offline after missed heartbeats (respects `CurrentLoad > 0`).
+- **Database unreachable** — confirm Postgres health; check connection pool (`MAGIC_POSTGRES_POOL_MAX`). Failover to replica if configured.
+- **Cost controller pausing workers unexpectedly** — check budget policy and `TotalCostToday` (midnight UTC reset). Review `cost.recorded` / `budget.exceeded` events.
+- **Memory / CPU spike** — check `magic_events_dropped_total` (event bus back-pressure). Consider restart with increased resources.
+
+If you can't identify the root cause in 15 minutes on a SEV-1, **roll back** and then investigate in a clean environment.
+
+## Communication Templates
+
+### Internal — first update (within 10 min)
+
+```
+:rotating_light: INCIDENT: <short title>
+Severity: SEV-1
+Started: <UTC timestamp>
+Detected by: <alert name / customer report>
+Impact: <what customers see>
+Commander: @<name>
+Scribe: @<name>
+Status: investigating
+Next update: in 15 minutes
+```
+
+### Internal — status update
+
+```
+:wrench: UPDATE <time UTC>
+Status: <investigating | identified | mitigating | monitoring | resolved>
+What we know: <one line>
+What we're doing: <one line>
+Blockers: <one line or "none">
+Next update: in <N> minutes
+```
+
+### Public status page — investigating
+
+> We are investigating reports of elevated error rates affecting <service area>. We will post an update within 30 minutes or sooner. Customers may experience <symptom>.
+
+### Public status page — identified + mitigating
+
+> We have identified the cause of the elevated error rates as <brief, non-sensitive description>. A mitigation is in progress. Next update at <time UTC>.
+
+### Public status page — resolved
+
+> The incident affecting <service area> was resolved at <time UTC>. Duration: <HH:MM>. Root cause and follow-up actions will be published in a postmortem within 5 business days.
+
+### Customer email — major incident
+
+```
+Subject: [Action required | FYI] MagiC service incident — <date>
+
+Hi <customer>,
+
+Between <start UTC> and <end UTC> you may have experienced <impact>.
+Root cause: <short description, no internal jargon>.
+Mitigation: <what we did>.
+Follow-up: <what we will do, and by when>.
+Data: <whether any customer data was affected — be specific>.
+
+For details, see our postmortem: <link>.
+For questions, reply to this email or write to <support contact>.
+
+Thank you for your patience.
+```
+
+**Regulatory notifications** (GDPR Art. 33, HIPAA breach rule) follow separate timelines — see [GDPR](../compliance/gdpr.md) and [HIPAA](../compliance/hipaa.md). Legal owns the regulator-facing message.
+
+## After the Incident — Postmortem
+
+Write a **blameless** postmortem within 5 business days of any SEV-1 or SEV-2. Target audience: engineers who didn't participate.
+
+Use this template:
+
+```markdown
+# Postmortem — <title> — <YYYY-MM-DD>
+
+## Summary
+1-2 sentence description of what happened and the impact.
+
+## Impact
+- Who was affected? (customers, orgs, internal teams)
+- Over what time window? (UTC timestamps)
+- What was the measurable impact? (errors, data, revenue)
+
+## Timeline (all UTC)
+- HH:MM — event or action.
+- HH:MM — event or action.
+...
+
+## Root Cause
+The underlying condition that allowed the incident. Not the trigger.
+
+## 5 Whys
+1. Why did X happen? Because Y.
+2. Why did Y happen? Because Z.
+...
+
+## What Went Well
+- ...
+
+## What Went Poorly
+- ...
+
+## Where We Got Lucky
+- ...
+
+## Action Items
+
+| # | Action | Owner | Target date | Ticket |
+|---|--------|-------|-------------|--------|
+| 1 | ...    | @...  | YYYY-MM-DD  | #...   |
+
+## Glossary
+Terms newcomers might not know.
+```
+
+### Principles
+
+- **Blameless.** Describe actions without naming individuals where possible. Focus on systems, not people.
+- **Honest.** Write the timeline as it happened, including missteps.
+- **Actionable.** Every finding maps to at least one follow-up with an owner and a date.
+- **Published.** Internally by default. Publish a redacted version externally for customer-impacting incidents.
+
+## Tools and Integrations
+
+Recommended stack (deployment-specific; mix and match):
+
+- **Paging:** PagerDuty, Opsgenie, Grafana OnCall.
+- **Status page:** Statuspage.io, Instatus, self-hosted cstate.
+- **Incident channel:** Slack, Discord, Zulip.
+- **Metrics / alerting:** Prometheus + Alertmanager (point it at MagiC's `/metrics`).
+- **Logs:** ship structured JSON logs to your log store (Loki, Elasticsearch, Datadog).
+- **Incident command:** templates in this file; FireHydrant, Jeli, incident.io for larger teams.
+
+Wire MagiC events to your tooling by subscribing a webhook to `task.failed`, `budget.exceeded`, and `audit.denied`.
+
+## Tabletop Exercises
+
+Run a tabletop exercise at least quarterly. Pick a scenario from:
+
+- Database primary fails.
+- Region outage.
+- Leaked `MAGIC_API_KEY`.
+- Compromised worker token.
+- Webhook delivery stalled.
+- LLM provider outage.
+
+Role-play the response for 60 minutes. Debrief. Update this runbook with any gap you find.

+# Upgrade Guide
+
+This guide covers upgrading a running MagiC deployment: versioning policy, pre-upgrade checks, rollout strategies, database migrations, and rollback.
+
+## Versioning Policy
+
+MagiC follows [Semantic Versioning 2.0.0](https://semver.org/).
+
+| Segment | Meaning | What to expect |
+|---------|---------|----------------|
+| **MAJOR** (X.y.z) | Breaking changes | API removals, protocol-incompatible changes, config-format rewrites. Requires deliberate planning and usually a deprecation cycle. |
+| **MINOR** (x.Y.z) | Additive, backward-compatible | New endpoints, new fields, new config options with safe defaults. Can be rolled in place. |
+| **PATCH** (x.y.Z) | Bug fixes | No new features. Safe to deploy without reading much. Security patches ship as patch releases. |
+
+Before `1.0.0` we may ship breaking changes in MINOR releases but always document them in [`CHANGELOG.md`](../../CHANGELOG.md) with migration notes.
+
+## Deprecation Policy
+
+When a feature is deprecated:
+
+1. It is announced in `CHANGELOG.md` under the deprecation's release.
+2. A runtime warning is logged each time the deprecated path is hit.
+3. The feature continues to work for at least **one full MINOR release**.
+4. It is removed in the release after that MINOR, announced in the `### Removed` section.
+
+Example timeline:
+
+- `0.9.0` — feature deprecated, warning added.
+- `0.10.0` — still works, still warns.
+- `0.11.0` — removed.
+
+## Pre-Upgrade Checklist
+
+Run through this every time, no matter how small the bump looks.
+
+- [ ] Read [`CHANGELOG.md`](../../CHANGELOG.md) from your current version to target. Flag any `### Changed` or `### Removed`.
+- [ ] Read the release notes for the target version on GitHub Releases.
+- [ ] Take a fresh backup — see [Backup & Restore](backup-restore.md).
+- [ ] Record the current migration version:
+      ```bash
+      migrate -database "$MAGIC_POSTGRES_URL" -path core/internal/store/migrations version
+      ```
+- [ ] Snapshot Prometheus dashboards / grab a baseline for error rate, p95 latency, worker count.
+- [ ] Test the target version in **staging** with production-like load, minimum 1 hour.
+- [ ] Have the rollback plan open in another tab. Rehearse it.
+- [ ] Announce the maintenance window internally and (if customer-impacting) externally.
+
+## Version Skew
+
+MagiC core ↔ SDK version skew is generally safe **within one MAJOR boundary**:
+
+- A newer server accepts older clients (SDKs) that speak the same MAJOR version.
+- A newer client may call endpoints that don't exist on an older server — expect 404.
+
+Roll SDKs **after** the server is upgraded, and pin SDK versions in client apps.
+
+## Rollout Strategies
+
+### Single instance (dev, small prod)
+
+```bash
+# 1. Backup
+pg_dump ... > pre-upgrade.dump
+
+# 2. Stop MagiC
+systemctl stop magic  # or kill the process / stop docker
+

+

+# Point at the target chart version + image tag
+helm upgrade magic ./deploy/helm/magic \
+  --reuse-values \
+  --set image.tag=v0.9.0 \
+  --wait \
+  --timeout 10m
+
+# Check pod rollout
+kubectl rollout status deploy/magic
+```
+
+Kubernetes does a rolling update by default. Ensure:
+
+- `replicas >= 2`.
+- PodDisruptionBudget allows a single pod down.
+- `maxSurge=1`, `maxUnavailable=0` for zero-downtime.
+- **Cluster mode** (leader election via Postgres advisory lock) is enabled when running multiple replicas.
+
+Database migrations run on pod startup. With rolling update, the **first** pod to start the new version runs the migration while older pods still serve traffic. Additive migrations (add column, add table, add index concurrently) are safe with this pattern. Destructive migrations (drop column, rename) are **not** — plan these as two-phase migrations across two releases.
+
+### Canary / Blue-Green
+
+For higher-risk releases:
+
+1. Deploy the new version behind a different service name (`magic-canary`).
+2. Route a small fraction of traffic (10%) via your load balancer, service mesh, or API gateway.
+3. Watch metrics and logs for 30-60 minutes.
+4. Shift traffic gradually (10% → 50% → 100%).
+5. Decommission the old version.
+
+This assumes the release does not include incompatible migrations. If it does, either both versions must tolerate both schemas during the window, or you must do a full cutover with a short downtime.
+
+## Database Migrations
+
+MagiC uses [`golang-migrate`](https://github.com/golang-migrate/migrate) with SQL files in `core/internal/store/migrations/`.
+
+Migrations are applied automatically on server startup by reading the `schema_migrations` table.
+
+### Additive migrations (zero-downtime)
+
+- Add new nullable columns.
+- Add new tables.
+- Add indexes `CREATE INDEX CONCURRENTLY` (Postgres).
+- Add new JSONB fields.
+
+These are safe with rolling update.
+
+### Destructive migrations (requires planning)
+
+- Dropping a column.
+- Renaming a column.
+- Making a nullable column `NOT NULL`.
+- Changing types.
+
+Handle these as a **two-phase release**:
+
+1. **Release N:** new code tolerates both old and new schema (reads/writes both). Ship.
+2. **Release N+1:** run destructive migration. Ship.
+
+Never combine a destructive migration with a breaking code change in the same release.
+
+### Manual migration control
+
+If your deployment policy requires separating migration from deploy:
+
+```bash
+# Dry run — inspect what migrate would do
+migrate -database "$MAGIC_POSTGRES_URL" -path core/internal/store/migrations version
+
+# Apply up to target version
+migrate -database "$MAGIC_POSTGRES_URL" -path core/internal/store/migrations up
+
+# Roll back one migration (with a confirmed backup!)
+migrate -database "$MAGIC_POSTGRES_URL" -path core/internal/store/migrations down 1
+```
+
+To disable the built-in migrator and run migrations externally, **pin the image to a version whose migrations you have already applied**. We do not yet expose a `MAGIC_AUTO_MIGRATE=false` flag; if you need one, open an issue.
+
+## Rollback
+
+Plan A: **roll back the deployment** (no schema change).
+
+- Helm: `helm rollback magic <previous-revision>`
+- Docker Compose: change tag, `docker compose up -d`.
+- Systemd: swap the binary, `systemctl restart magic`.
+
+Plan B: **destructive migration in the release — restore database.**
+
+1. Stop all MagiC pods (scale to 0 or `systemctl stop`).
+2. Restore the pre-upgrade backup — see [Backup & Restore](backup-restore.md).
+3. Redeploy the previous version.
+4. Start.
+
+This is disruptive. Better to avoid destructive migrations in the same release as anything else.
+
+## Post-Upgrade Verification
+
+- [ ] `/health` reports ready.
+- [ ] `/metrics` returns the expected Prometheus payload.
+- [ ] A canary task round-trips end-to-end.
+- [ ] Workers re-register (or resume heartbeats).
+- [ ] Webhook deliveries are clearing the queue.
+- [ ] Error rate, p95 latency, and saturation are within the baseline.
+- [ ] No new entries in the DLQ for 15 minutes.
+- [ ] Run a spot-check query against the audit log — entries should be landing.
+
+Keep a rollback window of at least one business day. Don't take the previous version offline immediately.
+
+## Upgrading the Go Runtime
+
+MagiC currently targets **Go 1.25+**. The Go version is documented in `go.mod` and in the Dockerfile. Upgrading to a newer Go minor version is an internal concern; downstream consumers do not need to track it. If you vendor the source, ensure your Go toolchain matches the stated minimum.
+
+## Upgrading Postgres
+
+MagiC supports Postgres 13+ (pgvector requires 11+; 15+ recommended).
+
+Major-version Postgres upgrades are a dedicated operation:
+
+- Use `pg_upgrade` for in-place major version upgrades.
+- Use `pg_dump` + `pg_restore` for cross-provider or cross-version migration.
+- Test the pgvector extension version compatibility first (`SELECT * FROM pg_extension`).
+
+After the Postgres upgrade, restart MagiC. Its migrations will re-check `schema_migrations` and no-op if already current.
+
+## Upgrading SDKs
+
+- **Python:** pin in `requirements.txt` or `pyproject.toml`. Upgrade with `pip install -U magic-ai-sdk`.
+- **Go:** `go get github.com/kienbui1995/magic/sdk/go@<version>`.
+- **TypeScript:** `npm install @magic-ai/sdk@<version>`.
+
+SDK upgrades are independent of server upgrades within the same MAJOR version.

+# Security Best Practices
+
+MagiC is infrastructure for managing AI workloads. Treating the supply chain, secrets, and release pipeline with rigor is a first-class concern. This document describes the practices enforced in this repository and the ones expected of contributors.
+
+## Supply chain security
+
+We run layered scanning on every pull request and on a weekly schedule.
+
+- **Dependabot** (`.github/dependabot.yml`) — opens weekly PRs for Go modules (`core/`, `sdk/go/`), Python (`sdk/python/`), npm (`sdk/typescript/`, root VitePress), Docker base images, and GitHub Actions. PRs are grouped and auto-labeled `dependencies`.
+- **govulncheck** (`ci.yml` job) — scans Go modules for known CVEs from the Go vulnerability database on every PR. Runs against `core` and `sdk/go` so a shared dependency cannot slip in.
+- **gosec** (`ci.yml` job) — static application security testing for Go. Uploads SARIF to GitHub code scanning so findings show up in the Security tab.
+- **CodeQL** (`codeql.yml`) — semantic code analysis for Go and JavaScript. Detects injection, data flow, and other deep issues beyond pattern-based SAST.
+- **OpenSSF Scorecard** (`scorecard.yml`) — weekly benchmark of repository security posture (branch protection, pinned actions, token permissions, signed releases). Score is published on the README badge.
+
+Each job runs as an independent workflow job so a single failure does not take the whole pipeline down.
+
+## Secret handling
+
+- **Never commit secrets.** `.env`, `.env.*`, and files matching `*credentials*` are in `.gitignore`. The CI job that publishes to PyPI uses OIDC (no long-lived token). GHCR uses the ephemeral `GITHUB_TOKEN`.
+- **GitHub repository secrets** are the only place long-lived credentials live. `NPM_TOKEN` is scoped to the typescript package only. Rotate yearly.
+- **Environment validation** — production backends must validate all required env vars at startup (Pydantic Settings for Python, typed config struct for Go) so misconfiguration fails fast.
+- If you believe a secret has leaked, rotate immediately and open an issue using the template `security-disclosure`. Do not file public issues for active credential leaks — follow `SECURITY.md`.
+
+## Commits and releases
+
+- **Signed commits recommended** — maintainers sign all merges to `main` with GPG or SSH. Contributors are encouraged but not required to sign. We plan to make signing mandatory for `main` once the contributor community is fully onboarded.
+- **Conventional Commits** — commit messages follow `feat(scope): …`, `fix(scope): …`, etc. Release notes are generated from the commit log.
+- **Release artifacts** — binaries for linux/amd64, linux/arm64, darwin/amd64, darwin/arm64 are built in the release workflow, checksummed (SHA-256), and published to GitHub Releases. Container images are pushed to GHCR for the same arch pair.
+- **Future work — artifact signing.** We plan to add Sigstore cosign signing for both container images and binaries, plus SLSA build provenance attestation, so downstream consumers can verify the build came from our CI.
+
+## Vulnerability disclosure
+
+Security issues must not be filed as public GitHub issues. Follow the contact and disclosure policy in [`SECURITY.md`](../../SECURITY.md). We aim to acknowledge within 48 hours and patch critical issues within 7 days.

+# OAuth2 / OIDC / JWT Authentication
+
+MagiC supports enterprise SSO via OpenID Connect. When enabled, the
+gateway accepts JWT bearer tokens issued by your identity provider
+alongside the existing `MAGIC_API_KEY`. Worker tokens (`mct_` prefix)
+are unaffected.
+
+Verified against any OIDC-compliant provider, including:
+
+- **Okta** — `https://<tenant>.okta.com`
+- **Azure AD / Microsoft Entra** — `https://login.microsoftonline.com/<tenant-id>/v2.0`
+- **Auth0** — `https://<tenant>.auth0.com/`
+- **Google Workspace** — `https://accounts.google.com`
+- **Keycloak** — `https://<host>/realms/<realm>`
+
+## Configuration
+
+| Env var | Required | Description |
+|---|---|---|
+| `MAGIC_OIDC_ISSUER` | yes | Issuer URL. MagiC discovers `<issuer>/.well-known/openid-configuration` at startup. |
+| `MAGIC_OIDC_CLIENT_ID` | yes* | Expected `aud` claim. *Required unless `MAGIC_OIDC_AUDIENCE` is set. |
+| `MAGIC_OIDC_AUDIENCE` | optional | Override `aud` (use when access-token `aud` differs from client ID — common on Auth0 / Okta custom authz servers). |
+
+If `MAGIC_OIDC_ISSUER` is unset, OIDC is disabled and behavior is
+identical to previous releases (API-key auth only).
+
+## How it works
+
+1. Client sends `Authorization: Bearer <jwt>`.
+2. Gateway middleware inspects the token. If shaped like a JWT
+   (`ey...` with 3 dot-separated segments), it verifies against the
+   issuer's JWKS (signature, `iss`, `aud`, `exp`, `nbf`).
+3. On success, claims (`sub`, `email`, `org_id`, `roles`) are attached
+   to the request context, and the API-key check is bypassed.
+4. On failure, 401 is returned. Non-JWT tokens (opaque API keys, worker
+   tokens) fall through to their respective middlewares — fully
+   backward compatible.
+
+JWKS keys are cached and auto-refreshed; a 60-second clock-skew
+tolerance is applied.
+
+## Custom claims mapping
+
+MagiC reads two non-standard claims for authorization:
+
+- `org_id` — the org the user belongs to. Used by the RBAC middleware
+  to scope the request.
+- `roles` — array of role names (`owner`, `admin`, `viewer`). If
+  present, bypasses the store-backed role-binding check.
+
+Your IdP must be configured to include these in the token. Typical
+mappings:
+
+- **Okta** — Authorization Server → Claims → add `org_id` (from user
+  profile attribute) and `roles` (from group memberships).
+- **Azure AD** — App registration → Token configuration → add optional
+  claim from group or extension attribute.
+- **Auth0** — Action on Login flow: `api.idToken.setCustomClaim("org_id", event.user.app_metadata.org_id)`.
+- **Google Workspace** — only standard claims; use path-scoped RBAC
+  (`/orgs/{orgID}/...`) or map via an intermediary IdP.
+
+## Per-provider setup
+
+### Okta
+
+1. Admin → Applications → Create App Integration → OIDC / Web.
+2. Copy **Client ID**.
+3. Issuer = `https://<tenant>.okta.com` (default authorization server)
+   or `https://<tenant>.okta.com/oauth2/<custom>` (custom authz server).
+4. Set `MAGIC_OIDC_ISSUER`, `MAGIC_OIDC_CLIENT_ID`.
+
+### Azure AD (Entra)
+
+1. Entra → App registrations → New → Web.
+2. Copy **Application (client) ID** and **Tenant ID**.
+3. Issuer = `https://login.microsoftonline.com/<tenant-id>/v2.0`.
+4. For access tokens (not ID tokens), set `MAGIC_OIDC_AUDIENCE` to the
+   API's Application ID URI (e.g. `api://magic`).
+
+### Auth0
+
+1. Dashboard → Applications → Create Application → Regular Web App.
+2. Copy **Client ID**.
+3. Issuer = `https://<tenant>.auth0.com/` (trailing slash required).
+4. If using API authorization, set `MAGIC_OIDC_AUDIENCE` to your
+   API identifier.
+
+### Google Workspace
+
+1. Cloud Console → APIs & Services → Credentials → OAuth client ID →
+   Web application.
+2. Issuer = `https://accounts.google.com`.
+3. Client ID → `MAGIC_OIDC_CLIENT_ID`.
+
+### Keycloak
+
+1. Create realm and client (Access Type: confidential or public).
+2. Issuer = `https://<host>/realms/<realm>`.
+3. Map realm roles to a `roles` token claim.
+
+## Gotchas
+
+- **Clock skew** — 60s tolerance baked in. Beyond that, ensure NTP on
+  the MagiC host.
+- **Key rotation** — JWKS is fetched lazily and cached by go-oidc;
+  rotation is seamless.
+- **Audience mismatch** — most common cause of 401. Verify `aud` in
+  the decoded token (jwt.io) matches `MAGIC_OIDC_CLIENT_ID` or
+  `MAGIC_OIDC_AUDIENCE`.
+- **Discovery timeout** — 10s at startup. If the provider is slow or
+  unreachable, the server fails to start (fail-fast by design).
+- **Token size** — large group/role claims can blow up cookie size in
+  browser flows; prefer scoped roles in the JWT.
+
+## Not yet supported
+
+- Token introspection (RFC 7662) — opaque access tokens.
+- Refresh-token flow orchestrated by MagiC (clients handle this today).
+- Device authorization grant (RFC 8628).
+- mTLS client authentication.

+# PostgreSQL Row-Level Security (RLS)
+
+MagiC enforces tenant isolation at the database layer using PostgreSQL Row-Level
+Security. RLS is a defence-in-depth layer **below** the application's `org_id`
+filtering: even if a Go handler forgets to scope a query, the database itself
+refuses to return another org's rows.
+
+## Tables under RLS
+
+Migration `005_rls.up.sql` enables RLS and installs one policy per table:
+
+| Table                | Predicate                                   |
+| -------------------- | ------------------------------------------- |
+| `workers`            | `data->>'org_id' = current_org`             |
+| `webhooks`           | `data->>'org_id' = current_org`             |
+| `webhook_deliveries` | `data->>'org_id' = current_org`             |
+| `policies`           | `data->>'org_id' = current_org`             |
+| `role_bindings`      | `data->>'org_id' = current_org`             |
+| `worker_tokens`      | `data->>'org_id' = current_org`             |
+| `audit_log`          | `data->>'org_id' = current_org`             |
+| `tasks`              | `data->'context'->>'org_id' = current_org`  |
+| `workflows`          | `data->'context'->>'org_id' = current_org`  |
+| `knowledge`          | `scope <> 'org' OR scope_id = current_org`  |
+
+`current_org` is `COALESCE(current_setting('app.current_org_id', true), '')`,
+wrapped in a stable SQL function `magic_current_org()`.
+
+## Bypass mode (empty variable)
+
+Every policy starts with `magic_current_org() = '' OR ...`. When the session
+variable is unset or empty, RLS passes all rows through — this is the default
+state of a freshly acquired pool connection. Rationale:
+
+- **Backward compatibility.** Existing Go code that has not been updated to
+  call `SetOrgContext` continues to work.
+- **Admin/cron paths.** Webhook dispatcher, migration runners, audit exporters
+  need to read across all orgs.
+- **Opt-in hardening.** RLS only kicks in once the gateway's auth middleware
+  starts setting `app.current_org_id` to the authenticated token's org.
+
+## Application API
+
+`store.PostgreSQLStore` exposes two complementary entry points.
+
+### 1. Context-scoped (automatic, used by the gateway)
+
+```go
+ctx = store.WithOrgIDContext(ctx, orgID)
+// every store call on this ctx runs under RLS for orgID
+workers := s.ListWorkers(ctx)
+```
+
+The pool is configured with `pgxpool.Config.BeforeAcquire` / `AfterRelease`
+hooks. When a connection is acquired with a ctx that carries an orgID,
+BeforeAcquire runs `SET app.current_org_id`; AfterRelease always resets the
+value before the connection returns to the pool so it can't leak to the next
+request. Empty orgID (or a non-postgres backend) is a no-op.
+
+### 2. Explicit closure (for code paths that hold a conn directly)
+
+```go
+func (s *PostgreSQLStore) WithOrgContext(
+    ctx context.Context,
+    orgID string,
+    fn func(conn *pgxpool.Conn) error,
+) error
+```
+
+Useful for tests and for any caller that needs to run multiple statements on
+a single pinned connection.
+
+## Runtime wiring (gateway)
+
+The middleware chain is (outer → inner):
+
+```
+otel → cors → securityHeaders → apiVersion → oidc → auth → bodySize
+     → requestID → rbac → rlsScope → mux
+```
+
+`rlsScopeMiddleware` (in `internal/gateway/middleware.go`) runs after auth/rbac
+have populated the context and extracts the orgID from, in priority order:
+
+1. OIDC JWT claims (`auth.ClaimsFromContext(ctx).OrgID`)
+2. Worker token (`gateway.TokenFromContext(ctx).OrgID`)
+3. Path parameter `{orgID}` for `/api/v1/orgs/{orgID}/...`
+
+It then stamps the context via `store.WithOrgIDContext`. The first store call
+triggers `BeforeAcquire`, which engages RLS for the rest of the request.
+
+When no source is available (health checks, dev mode without auth, admin
+bootstrap) the ctx is left untouched → `app.current_org_id` stays empty →
+RLS bypasses (see "Bypass mode" above). This preserves backward compatibility
+and keeps cross-org admin flows working.
+
+## Production deployment checklist
+
+1. Apply migration 005 (`RunMigrations` does this automatically).
+2. Connect MagiC as a **non-superuser** PostgreSQL role.
+   Superusers and table owners bypass RLS by default:
+   ```sql
+   CREATE ROLE magic_app LOGIN PASSWORD '...' NOSUPERUSER NOBYPASSRLS;
+   GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA public TO magic_app;
+   ```
+3. The gateway's `rlsScopeMiddleware` now stamps `ctx` with the caller's
+   orgID on every request — no application-level action required. Verify
+   by checking the middleware chain in `internal/gateway/gateway.go`.
+4. Admin CLIs / migration runners should connect with an account that is
+   expected to bypass RLS, or leave `app.current_org_id` unset.
+
+## Performance
+
+All RLS predicates are backed by expression indexes (see migration 005):
+
+- `idx_tasks_context_org`, `idx_workflows_context_org` for nested JSONB paths.
+- `idx_webhooks_org`, `idx_policies_org`, `idx_role_bindings_org`,
+  `idx_worker_tokens_org`, `idx_webhook_deliveries_org`.
+- `idx_knowledge_scope` compound index for the scope/scope_id predicate.
+
+EXPLAIN a typical `SELECT ... FROM tasks` under RLS to confirm the planner
+uses the index; if it doesn't, run `ANALYZE` to refresh statistics.
+
+## Testing
+
+`core/internal/store/postgres_rls_test.go` verifies:
+
+1. Two orgs are seeded with disjoint workers + tasks.
+2. Admin (empty var) sees all rows.
+3. Under `WithOrgContext(orgA)`, orgB rows are invisible at the SQL layer
+   (even an unscoped `SELECT COUNT(*) FROM workers` returns only orgA).
+4. After `WithOrgContext` returns, the pool connection is back in bypass mode.
+5. A worker with a SQL-injection-shaped name (`' OR 1=1 --`) stays isolated
+   to its org — RLS is enforced regardless of payload content.
+
+`core/internal/gateway/rls_test.go` adds an HTTP-level integration test
+(`TestRLS_CrossTenantIsolation_Postgres`) that spins up the full gateway
+against a real postgres, issues two worker tokens for two orgs, and
+asserts an orgB bearer token cannot observe orgA workers via
+`GET /api/v1/workers` — RLS enforced end-to-end, not just at the store.
+
+Run either suite with:
+
+```bash
+MAGIC_POSTGRES_URL="postgres://user:pass@localhost/magic_test?sslmode=disable" \
+  go test -race -count=1 ./internal/store/... ./internal/gateway/...
+```
+
+Tests skip when `MAGIC_POSTGRES_URL` is not set, following the existing
+pattern.
+
+## Troubleshooting
+
+RLS not filtering as expected? Run the checklist:
+
+1. **Connected as a superuser or table owner?** These bypass RLS by default.
+   Run `SELECT current_user;` and confirm it's `magic_app` (or your
+   non-superuser role).
+2. **Migration 005 applied?** `SELECT relname, relrowsecurity FROM pg_class
+   WHERE relname IN ('workers','tasks','workflows');` — all three must show
+   `t`.
+3. **`app.current_org_id` actually set?** Add a log line around the failing
+   query: `SELECT current_setting('app.current_org_id', true);`. If empty,
+   the BeforeAcquire hook didn't fire → ctx was never stamped → check that
+   the handler received an authenticated request (OIDC claim or worker
+   token).
+4. **Using the right ctx?** Store methods must receive the request-scoped
+   ctx. A goroutine spawned with `context.Background()` will acquire a
+   connection with no orgID → RLS bypass. Propagate ctx or re-stamp.
+5. **Mixed statements on one conn?** If you use `WithOrgContext` and
+   simultaneously another goroutine uses the same store, each acquires its
+   own conn — they don't interfere, but each is responsible for its own
+   scope.
+
+## Rollback
+
+`005_rls.down.sql` drops every policy, disables RLS on each table, removes
+the supporting indexes, and drops `magic_current_org()`. Safe to apply on a
+running system.

+# Secret Management
+
+MagiC reads sensitive configuration (API keys, database URLs, LLM credentials)
+through a pluggable `SecretProvider` abstraction defined in
+`core/internal/secrets`. The default is a zero-dependency environment-variable
+provider; enterprise deployments can plug in HashiCorp Vault or AWS Secrets
+Manager without changing call sites.
+
+## Providers
+
+| Provider | `MAGIC_SECRETS_PROVIDER` | Status | Dependencies |
+|----------|--------------------------|--------|--------------|
+| Env      | `env` (default)          | Ready  | none |
+| Vault    | `vault`                  | Stub   | `github.com/hashicorp/vault/api` (vendor to enable) |
+| AWS      | `aws`                    | Stub   | `github.com/aws/aws-sdk-go-v2/service/secretsmanager` (vendor to enable) |
+
+Stubs validate config at construction and return `ErrProviderUnavailable`
+from `Get()` with a pointer back to this document. They intentionally do
+not dial the backend — startup never blocks on a secret store.
+
+## Environment Variables
+
+### Selection
+
+- `MAGIC_SECRETS_PROVIDER` — one of `env`, `vault`, `aws`. Empty = `env`.
+
+### Vault (`vault`)
+
+- `MAGIC_VAULT_ADDR` (required) — e.g. `https://vault.example.com:8200`
+- `MAGIC_VAULT_TOKEN` (required) — prefer a token helper in production
+- `MAGIC_VAULT_MOUNT` (default `secret`) — KVv2 mount point
+- `MAGIC_VAULT_PATH` — base path under the mount, e.g. `magic/prod`
+
+### AWS Secrets Manager (`aws`)
+
+- `AWS_REGION` (required) — e.g. `ap-southeast-1`
+- `MAGIC_AWS_SECRETS_PREFIX` — e.g. `magic/prod/`; prepended to the
+  secret name before lookup
+
+## Implementing a Production Provider
+
+The `Provider` interface is intentionally small:
+
+```go
+type Provider interface {
+    Get(ctx context.Context, name string) (string, error)
+    Name() string
+}
+```
+
+To enable Vault, vendor `github.com/hashicorp/vault/api` and replace the
+stub body in `core/internal/secrets/vault.go`:
+
+```go
+func (v *VaultProvider) Get(ctx context.Context, name string) (string, error) {
+    client, err := vault.NewClient(&vault.Config{Address: v.cfg.Address})
+    if err != nil { return "", err }
+    client.SetToken(v.cfg.Token)
+    sec, err := client.KVv2(v.cfg.Mount).Get(ctx, path.Join(v.cfg.Path, name))
+    if err != nil { return "", err }
+    raw, ok := sec.Data["value"].(string)
+    if !ok { return "", secrets.ErrNotFound }
+    return raw, nil
+}
+```
+
+For AWS, vendor `aws-sdk-go-v2` and implement `GetSecretValue` analogously
+in `aws.go`. Re-use the existing config struct and `ErrNotFound` /
+`ErrProviderUnavailable` sentinels.
+
+## ChainProvider — Layered Lookups
+
+`secrets.NewChainProvider(primary, fallback, ...)` walks providers in
+priority order and returns the first hit. `ErrNotFound` falls through;
+any other error (including `ErrProviderUnavailable`) short-circuits so
+misconfiguration is never silently masked.
+
+Recommended pattern for mixed dev/prod environments:
+
+```go
+p := secrets.NewChainProvider(
+    secrets.NewEnvProvider(),   // dev overrides / CI
+    vault,                      // production source of truth
+)
+```
+
+## Migration Path: env → vault without downtime
+
+1. Deploy the binary with `MAGIC_SECRETS_PROVIDER=env` (current behavior).
+2. Populate Vault with the same keys. Keep env vars set as well.
+3. Switch to `ChainProvider(env, vault)` — env still wins, but vault is
+   primed and any missing keys fall through.
+4. Flip to `MAGIC_SECRETS_PROVIDER=vault` once Vault coverage is verified.
+5. Remove the env vars from the deployment and rotate secrets.
+
+## Rotation (Future Work)
+
+The abstraction does not yet expose a `Watch` / `OnRotate` callback.
+When a rotation story is needed, add:
+
+```go
+type RotatingProvider interface {
+    Provider
+    Watch(ctx context.Context, name string) (<-chan string, error)
+}
+```
+
+Vault's lease renewal and AWS Secrets Manager's rotation schedule both
+map to this shape. Callers type-assert for the capability.
+
+## Migrated Call Sites
+
+The following credentials now flow through `secrets.Provider` and are
+resolved at server startup in `cmd/magic/main.go` via
+`config.LoadWithSecrets(ctx, path, sp)`:
+
+| Secret name          | Purpose                         | Consumer |
+|----------------------|---------------------------------|----------|
+| `MAGIC_API_KEY`      | Admin API-key for gateway auth  | `gateway.authMiddleware` (read once; captured in closure) |
+| `MAGIC_POSTGRES_URL` | PostgreSQL connection string    | `store.NewPostgreSQLStore` |
+| `OPENAI_API_KEY`     | OpenAI LLM provider             | `llm.NewOpenAIProvider` |
+| `ANTHROPIC_API_KEY`  | Anthropic LLM provider          | `llm.NewAnthropicProvider` |
+
+With `MAGIC_SECRETS_PROVIDER=env` (default) the behavior is identical
+to reading `os.Getenv` directly. To source any of these from Vault or
+AWS Secrets Manager, implement the corresponding provider and set
+`MAGIC_SECRETS_PROVIDER`; no code changes are required at the call
+sites.
+
+### Non-secret knobs (stay on `os.Getenv`)
+
+These are operational knobs, not credentials, and continue to read
+`os.Getenv` directly:
+
+- `MAGIC_PORT`, `MAGIC_TRUSTED_PROXY`, `MAGIC_CORS_ORIGIN`
+- `MAGIC_POSTGRES_POOL_MIN`, `MAGIC_POSTGRES_POOL_MAX`, `MAGIC_PGVECTOR_DIM`
+- `MAGIC_STORE` (SQLite path), `OPENAI_BASE_URL`, `OLLAMA_URL`
+- `MAGIC_RATE_LIMIT_DISABLE`, `MAGIC_REDIS_URL`, `MAGIC_OIDC_*`
+- OpenTelemetry standard env vars (`OTEL_*`)
+
+Only genuine credentials go through the provider.

+# Release Signing & Build Provenance
+
+MagiC release artifacts are cryptographically signed and ship with SLSA Level 3
+build provenance. This page lists the exact commands to verify them.
+
+## What gets signed
+
+| Artifact | Signer | Format |
+|----------|--------|--------|
+| `magic-{linux,darwin}-{amd64,arm64}` binaries | Sigstore cosign (keyless, OIDC) | `.cosign.bundle` next to each file |
+| `checksums.sha256` | Sigstore cosign (keyless, OIDC) | `checksums.sha256.cosign.bundle` |
+| `ghcr.io/kienbui1995/magic@<digest>` container image | Sigstore cosign (keyless, OIDC) | Signature in Rekor transparency log |
+| Binaries (all) | SLSA GitHub Generator v2 | `multiple.intoto.jsonl` release asset |
+| Container image | SLSA GitHub Generator v2 | OCI provenance attestation in GHCR |
+
+Keyless signing means there is no long-lived private key. Each signature is
+tied to the GitHub Actions OIDC identity of the release workflow and logged
+to the public Rekor transparency log.
+
+## Prerequisites
+
+```bash
+# cosign >= 2.2
+brew install cosign          # or: go install github.com/sigstore/cosign/v2/cmd/cosign@latest
+
+# slsa-verifier >= 2.6
+go install github.com/slsa-framework/slsa-verifier/v2/cli/slsa-verifier@latest
+```
+
+## Verify a binary signature (cosign)
+
+```bash
+VERSION=v0.1.0
+FILE=magic-linux-amd64
+
+curl -LO https://github.com/kienbui1995/magic/releases/download/${VERSION}/${FILE}
+curl -LO https://github.com/kienbui1995/magic/releases/download/${VERSION}/${FILE}.cosign.bundle
+
+cosign verify-blob \
+  --bundle "${FILE}.cosign.bundle" \
+  --certificate-identity-regexp "^https://github.com/kienbui1995/magic/.github/workflows/release.yml@refs/tags/v" \
+  --certificate-oidc-issuer "https://token.actions.githubusercontent.com" \
+  "${FILE}"
+```
+
+Expected output: `Verified OK`.
+
+## Verify the container image signature (cosign)
+
+```bash
+IMAGE=ghcr.io/kienbui1995/magic:v0.1.0
+
+cosign verify \
+  --certificate-identity-regexp "^https://github.com/kienbui1995/magic/.github/workflows/release.yml@refs/tags/v" \
+  --certificate-oidc-issuer "https://token.actions.githubusercontent.com" \
+  "${IMAGE}"
+```
+
+## Verify SLSA provenance (binary)
+
+```bash
+VERSION=v0.1.0
+FILE=magic-linux-amd64
+
+curl -LO https://github.com/kienbui1995/magic/releases/download/${VERSION}/${FILE}
+curl -LO https://github.com/kienbui1995/magic/releases/download/${VERSION}/multiple.intoto.jsonl
+
+slsa-verifier verify-artifact \
+  --provenance-path multiple.intoto.jsonl \
+  --source-uri github.com/kienbui1995/magic \
+  --source-tag ${VERSION} \
+  "${FILE}"
+```
+
+## Verify SLSA provenance (container)
+
+```bash
+IMAGE=ghcr.io/kienbui1995/magic
+VERSION=v0.1.0
+
+DIGEST=$(docker buildx imagetools inspect ${IMAGE}:${VERSION} --format '{{json .Manifest}}' | jq -r .digest)
+
+slsa-verifier verify-image \
+  --source-uri github.com/kienbui1995/magic \
+  --source-tag ${VERSION} \
+  "${IMAGE}@${DIGEST}"
+```
+
+## Key rotation policy
+
+Keyless signing is tied to the GitHub workflow identity (OIDC). There is no
+long-lived key to rotate. If the release workflow is compromised:
+
+1. Revoke the GitHub Actions identity: disable `release.yml` on main.
+2. Publish an advisory listing affected release tags.
+3. Cut a new release from a clean state; old bundles remain in Rekor but the
+   advisory tells consumers which ranges to reject.
+
+## Trust-on-first-use — pin the identity
+
+When automating verification in a CI of your own, pin to the exact workflow
+path + tag pattern (as in the commands above). Do not rely on the repository
+name alone — the certificate identity is what cryptographically ties a
+signature to the workflow that produced it.

+# Postgres-backed E2E Tests
+
+The suite in `core/internal/e2e/postgres_test.go` (build tag `e2e`) exercises
+the real MagiC stack against an ephemeral PostgreSQL instance spun up by
+[testcontainers-go](https://golang.testcontainers.org/). It complements the
+MemoryStore E2E suite by catching regressions that only surface with a real
+database — migrations, Row-Level Security (RLS), pgxpool hooks, and
+concurrent pool pressure.
+
+## Why
+
+The MemoryStore E2E suite covers cross-module wiring but cannot validate:
+
+- SQL migrations (up + down reversibility, ordering, table dependencies)
+- RLS policies from migration 005 (`app.current_org_id` session variable)
+- pgxpool `BeforeAcquire` / `AfterRelease` hooks that engage RLS at runtime
+- Transactional rollback semantics (e.g. `UpdateWorkerToken` CAS)
+- Concurrency against a shared connection pool
+
+Running these against a real Postgres (with a non-superuser role so RLS is
+enforced) is the only way to catch those classes of bug before production.
+
+## Scenarios
+
+| Test | What it catches |
+|------|-----------------|
+| `TestE2E_Postgres_Migrations` | up creates every MagiC table; down reverses cleanly |
+| `TestE2E_Postgres_BasicCRUD` | Worker CRUD through `PostgreSQLStore` (not Memory) |
+| `TestE2E_Postgres_RLS_CrossTenantIsolation` | Two orgs seeded; `WithOrgIDContext(orgA)` hides orgB rows |
+| `TestE2E_Postgres_RLS_HTTPLevel` | Full gateway chain auth → rlsScopeMiddleware → store scopes correctly |
+| `TestE2E_Postgres_ConnectionPool_Concurrent` | 100 goroutines `AddTask` concurrently; no deadlock, all persisted |
+| `TestE2E_Postgres_BeforeAcquireHook` | Scoped ctx sets `app.current_org_id`; AfterRelease resets it for next caller |
+| `TestE2E_Postgres_TransactionRollback` | `UpdateWorkerToken` CAS conflict leaves original binding intact |
+
+Image: `pgvector/pgvector:pg16` (Postgres 16 + pgvector preinstalled — migration
+002 creates `knowledge_embeddings vector(1536)`).
+
+## Run locally
+
+```bash
+cd core
+go test -tags=e2e -race -count=1 -timeout=600s \
+    -run '^TestE2E_Postgres' ./internal/e2e/...
+```
+
+Requires a running Docker daemon reachable via the default socket
+(`/var/run/docker.sock` on Linux, `~/.docker/run/docker.sock` on macOS with
+Docker Desktop, or the named pipe on Windows).
+
+Expected runtime on a warm machine (image cached):
+
+| Component | Time |
+|-----------|------|
+| Container start + migrations | ~1.5 s per test |
+| Full Postgres suite | ~15 s |
+| With `-race` | ~25 s |
+
+The first run after `docker system prune` will pull `pgvector/pgvector:pg16`
+(~450 MB) and take 30–60 s longer.
+
+## How RLS is actually tested
+
+Postgres does not enforce RLS against superusers or table owners. The
+testcontainers `postgres` role is a superuser, so the helpers create a
+non-superuser `magic_app` role and hand the store a connection string
+authenticated as that role. This mirrors the production guidance in
+`docs/security/rls.md`.
+
+Without this step, the RLS policies from migration 005 would silently
+pass through every row — and the tests would give false confidence.
+
+## Fail modes & hints
+
+| Symptom | Likely cause | Fix |
+|---------|--------------|-----|
+| `docker required: Cannot connect to the Docker daemon` | Docker not running | `systemctl start docker` or open Docker Desktop |
+| `pull access denied for pgvector/pgvector` | Offline / registry blocked | Pre-pull: `docker pull pgvector/pgvector:pg16` |
+| `context deadline exceeded` during container start | Slow disk / cold cache | Warm the image once, re-run |
+| `relation "policies" does not exist` during migrate up | 005 references tables not in 001 | Fixed — 001 now creates `policies` and `role_bindings` |
+| `expected 2 workers visible under RLS, got 4` | Tests ran as superuser | Helper must create non-superuser role (ensured by `setupPostgresStore`) |
+
+If Docker is unavailable, each Postgres test calls `t.Skip` with the error —
+the MemoryStore suite still runs in `go test -tags=e2e`.
+
+## CI
+
+`.github/workflows/ci.yml` runs two separate jobs:
+
+- **e2e** — MemoryStore suite, no Docker dependency
+- **e2e-postgres** — this suite; uses the preinstalled Docker daemon on
+  GitHub-hosted `ubuntu-latest` runners
+
+The jobs run in parallel. A failure in one does not short-circuit the other.

+# Zero to Production in 30 Minutes
+
+Build a complete MagiC fleet from scratch: local dev → real AI agent → multi-tenant auth → production deployment.
+
+**Estimated time: 30 minutes** (6 phases, 5 min each)
+
+---
+
+## Phase 0: Prerequisites (2 minutes)
+
+You need:
+- **Docker** + Docker Compose (or Podman)
+- **Python 3.11+**
+- **Go 1.25+** (optional if using Docker for the server)
+- **curl** (for testing) or a REST client
+- **PostgreSQL CLI** (optional, for advanced steps)
+- **Helm 3.11+** (optional, for Kubernetes)
+
+Get the code:
+```bash
+git clone https://github.com/kienbui1995/magic.git
+cd magic
+```
+
+---
+
+## Phase 1: Local Dev with In-Memory Storage (5 minutes)
+
+Start with the simplest setup — no database, just MagiC in memory.
+
+### Build and run the server
+
+```bash
+cd core
+go build -o ../bin/magic ./cmd/magic
+cd ..
+./bin/magic serve
+```
+
+You should see:
+```
+[INFO] MagiC server starting on 0.0.0.0:8080
+[INFO] Store: memory (dev mode)
+[INFO] Ready
+```
+
+### Verify health
+
+In another terminal:
+```bash
+curl http://localhost:8080/health
+```
+
+Response:
+```json
+{
+  "status": "ok",
+  "version": "0.8.0",
+  "protocol_version": "1.0",
+  "uptime_seconds": 5
+}
+```
+
+### Check metrics
+
+```bash
+curl http://localhost:8080/metrics | head -20
+```
+
+You'll see Prometheus format: counters, gauges, histograms for tasks, workers, cost tracking.
+
+**Checkpoint: MagiC is running and responding. Proceed to Phase 2.**
+
+---
+
+## Phase 2: Persistence with PostgreSQL (5 minutes)
+
+In-memory mode loses data when you restart. Use Postgres for real persistence.
+
+### Start PostgreSQL (easiest: Docker)
+
+```bash
+docker run -d \
+  -e POSTGRES_PASSWORD=magic-dev \
+  -e POSTGRES_DB=magic \
+  -p 5432:5432 \
+  postgres:15-pgvector
+```
+
+Wait for it to be ready:
+```bash
+sleep 5 && pg_isready -h localhost
+```
+
+### Stop the running MagiC server and restart with Postgres
+
+```bash
+export MAGIC_POSTGRES_URL="postgres://postgres:magic-dev@localhost:5432/magic?sslmode=disable"
+./bin/magic serve
+```
+
+MagiC will:
+1. Create the `public` schema
+2. Run migrations automatically (from `core/internal/store/migrations/`)
+3. Print migration progress to stdout
+
+You should see:
+```
+[INFO] Applying migration: 001_init
+[INFO] Applying migration: 002_add_vectors
+[INFO] Applying migration: 003_add_dlq
+...
+[INFO] Ready
+```
+
+### Verify persistence
+
+Submit a simple task:
+```bash
+curl -X POST http://localhost:8080/api/v1/tasks \
+  -H "Content-Type: application/json" \
+  -d '{
+    "type": "test",
+    "input": {"msg": "persisted"}
+  }'
+```
+
+Copy the `task_id` from the response. Now kill MagiC (`Ctrl+C`) and restart it:
+
+```bash
+./bin/magic serve
+```
+
+Retrieve the task:
+```bash
+curl http://localhost:8080/api/v1/tasks/{task_id}
+```
+
+**It's still there.** The database survived the restart.
+
+**Checkpoint: Your data persists. Now add a real worker.**
+
+---
+
+## Phase 3: Add a Real AI Agent (5 minutes)
+
+Let's wrap CrewAI (or any agent framework) as a MagiC worker.
+
+### Option A: CrewAI (recommended for learning)
+
+```bash
+cd examples/integrations/crewai
+python -m venv .venv
+source .venv/bin/activate
+pip install -r requirements.txt
+cp .env.example .env
+```
+
+Edit `.env` to set `OPENAI_API_KEY`, or switch to Ollama:
+```env
+OPENAI_API_KEY=sk-...
+# OR for local-only:
+OPENAI_API_KEY=ollama
+OPENAI_API_BASE=http://localhost:11434/v1
+```
+
+Run the worker:
+```bash
+python main.py
+```
+
+You should see:
+```
+[INFO] Registering with MagiC...
+[INFO] CrewAI Worker registered as worker_abc123
+[INFO] Serving on 0.0.0.0:9101
+```
+
+### Option B: Simple Python worker (if you don't have OpenAI key)
+
+In another terminal, create `test-worker.py`:
+
+```python
+from magic_ai_sdk import Worker
+
+worker = Worker(name="SimpleBotter", endpoint="http://localhost:9002")
+
+@worker.capability("analyze", description="Analyzes text")
+def analyze(text: str) -> dict:
+    return {
+        "word_count": len(text.split()),
+        "length": len(text),
+        "summary": f"Text: {text[:50]}..."
+    }
+
+if __name__ == "__main__":
+    worker.register("http://localhost:8080")
+    worker.serve()
+```
+
+```bash
+python test-worker.py
+```
+
+### Submit a task to your worker
+
+From your main terminal:
+
+**For CrewAI:**
+```bash
+curl -X POST http://localhost:8080/api/v1/tasks \
+  -H "Content-Type: application/json" \
+  -d '{
+    "type": "research_and_write",
+    "input": {"topic": "MagiC Framework for AI Orchestration"},
+    "routing": {"required_capabilities": ["research_and_write"]},
+    "contract": {"timeout_ms": 120000, "max_cost": 1.0}
+  }'
+```
+
+**For SimpleBotter:**
+```bash
+curl -X POST http://localhost:8080/api/v1/tasks \
+  -H "Content-Type: application/json" \
+  -d '{
+    "type": "analyze",
+    "input": {"text": "Hello world from MagiC"}
+  }'
+```
+
+**Checkpoint: Your AI agent is running and producing real outputs. Check cost tracking next.**
+
+---
+
+## Phase 4: Multi-Tenant Auth and Cost Tracking (5 minutes)
+
+Add API keys and track spending.
+
+### Generate an admin API key
+
+```bash
+export MAGIC_API_KEY=$(openssl rand -hex 32)
+echo "API_KEY: $MAGIC_API_KEY"
+```
+
+Stop and restart MagiC with the key:
+```bash
+MAGIC_API_KEY="$MAGIC_API_KEY" ./bin/magic serve
+```
+
+### Create an organization token
+
+```bash
+curl -X POST http://localhost:8080/api/v1/orgs/acme/tokens \
+  -H "Authorization: Bearer $MAGIC_API_KEY" \
+  -H "Content-Type: application/json" \
+  -d '{"name": "dev-token"}'
+```
+
+Response:
+```json
+{
+  "token": "mct_abc...",
+  "org_id": "acme",
+  "created_at": "2026-04-18T10:30:00Z"
+}
+```
+
+### Use the token for worker registration
+
+```bash
+curl -X POST http://localhost:8080/api/v1/workers/register \
+  -H "Authorization: Bearer mct_abc..." \
+  -H "Content-Type: application/json" \
+  -d '{
+    "name": "TestWorker",
+    "capabilities": [{"name": "test", "description": "Test", "est_cost_per_call": 0.01}],
+    "endpoint": {"type": "http", "url": "http://localhost:9002"}
+  }'
+```
+
+### Check costs
+
+```bash
+curl http://localhost:8080/api/v1/costs \
+  -H "Authorization: Bearer $MAGIC_API_KEY"
+```
+
+Response:
+```json
+{
+  "org_id": "acme",
+  "total_cost_usd": 0.05,
+  "total_cost_today_usd": 0.03,
+  "budget_limit_usd": 100.0,
+  "warning_threshold_usd": 80.0
+}
+```
+
+### Set a budget limit (optional)
+
+```bash
+curl -X POST http://localhost:8080/api/v1/orgs/acme/budget \
+  -H "Authorization: Bearer $MAGIC_API_KEY" \
+  -H "Content-Type: application/json" \
+  -d '{"limit_usd": 10.0, "pause_on_exceed": true}'
+```
+
+Once spent reaches `$10.00`, new tasks are rejected with `429 Budget Exceeded`.
+
+**Checkpoint: Your fleet is now multi-tenant with cost controls. Deploy it next.**
+
+---
+
+## Phase 5: Deploy to Production (5 minutes)
+
+### Option A: Kubernetes with Helm (recommended)
+
+#### Prerequisites
+- Kubernetes 1.24+
+- Helm 3.11+
+- PostgreSQL instance (RDS, Neon, Supabase, or your own)
+
+#### Install
+
+```bash
+# 1. Get dependencies
+helm dependency update deploy/helm/magic/
+
+# 2. Prepare your values
+export MAGIC_API_KEY=$(openssl rand -hex 32)
+export POSTGRES_URL="postgres://user:pass@db.example.com:5432/magic?sslmode=require"
+
+# 3. Install
+helm install magic deploy/helm/magic/ \
+  --namespace magic \
+  --create-namespace \
+  --set secrets.apiKey="$MAGIC_API_KEY" \
+  --set secrets.postgresUrl="$POSTGRES_URL" \
+  --set image.tag=v0.8.0
+
+# 4. Verify rollout
+kubectl -n magic rollout status deploy/magic
+```
+
+Watch logs:
+```bash
+kubectl -n magic logs -l app.kubernetes.io/name=magic -f
+```
+
+Get the endpoint:
+```bash
+kubectl -n magic port-forward svc/magic 8080:80 &
+curl http://localhost:8080/health
+```
+
+### Option B: Docker Compose (for small self-hosted)
+
+Create `docker-compose.yml` in your project directory:
+
+```yaml
+version: '3.9'
+
+services:
+  postgres:
+    image: postgres:15-pgvector
+    environment:
+      POSTGRES_PASSWORD: ${DB_PASSWORD:-magic-prod}
+      POSTGRES_DB: magic
+    volumes:
+      - postgres_data:/var/lib/postgresql/data
+    ports:
+      - "5432:5432"
+
+  magic:
+    image: kienbui1995/magic:v0.8.0
+    ports:
+      - "8080:8080"
+    environment:
+      MAGIC_POSTGRES_URL: "postgres://postgres:${DB_PASSWORD:-magic-prod}@postgres:5432/magic?sslmode=disable"
+      MAGIC_API_KEY: ${MAGIC_API_KEY}
+      MAGIC_CORS_ORIGIN: "https://yourdomain.com"
+    depends_on:
+      - postgres
+    healthcheck:
+      test: ["CMD", "curl", "-f", "http://localhost:8080/health"]
+      interval: 10s
+      timeout: 5s
+      retries: 3
+
+volumes:
+  postgres_data:
+```
+
+Deploy:
+```bash
+export MAGIC_API_KEY=$(openssl rand -hex 32)
+docker compose up -d
+
+# Watch startup
+docker compose logs -f magic
+```
+
+Verify:
+```bash
+curl http://localhost:8080/health
+```
+
+### Production checklist
+
+- [ ] **Secrets**: `MAGIC_API_KEY` ≥ 32 chars, stored in Secret (not in code)
+- [ ] **Database**: PostgreSQL 13+ with pgvector extension
+- [ ] **TLS**: Ingress or reverse proxy (cert-manager, Let's Encrypt)
+- [ ] **CORS**: Set `MAGIC_CORS_ORIGIN` to your frontend domain
+- [ ] **Rate limiting**: Optional Redis backend for distributed multi-instance deploys
+- [ ] **Monitoring**: Enable Prometheus scraping on `/metrics`
+- [ ] **Backups**: Automated nightly Postgres backups
+- [ ] **Secrets provider**: Move secrets from env to Vault/Sealed Secrets/External Secrets
+- [ ] **Resource limits**: Set CPU/memory requests and limits
+- [ ] **Pod disruption budget**: For zero-downtime updates
+
+**Checkpoint: MagiC is production-ready. Now enable observability.**
+
+---
+
+## Phase 6: Observability (3 minutes)
+
+### Prometheus metrics (already exposed)
+
+MagiC exports metrics at `GET /metrics` (unauthenticated).
+
+```bash
+curl http://localhost:8080/metrics
+```
+
+Key metrics:
+- `magic_tasks_completed_total` — tasks finished successfully
+- `magic_tasks_failed_total` — tasks failed (requeue or DLQ)
+- `magic_workers_online` — active worker count
+- `magic_cost_total_usd` — organization spending
+- `magic_http_requests_duration_seconds` — request latency histogram
+
+### Grafana dashboard (optional)
+
+1. Point Prometheus at `http://magic:8080/metrics` (or your prod endpoint)
+2. Import the dashboard from `deploy/grafana/dashboards/magic-overview.json`
+3. Pin it to your ops dashboard
+
+### Slack alerts (optional)
+
+Register a webhook to send budget alerts to Slack:
+
+```bash
+curl -X POST http://localhost:8080/api/v1/orgs/acme/webhooks \
+  -H "Authorization: Bearer $MAGIC_API_KEY" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "events": ["budget.threshold"],
+    "url": "https://hooks.slack.com/services/YOUR/WEBHOOK/URL"
+  }'
+```
+
+When an organization hits 80% of budget, MagiC POSTs to that URL with:
+```json
+{
+  "type": "budget.threshold",
+  "org_id": "acme",
+  "total_cost_usd": 80.0,
+  "budget_limit_usd": 100.0,
+  "timestamp": "2026-04-18T15:30:00Z"
+}
+```
+
+### Distributed tracing (optional)
+
+If you have Jaeger or Tempo running:
+
+```bash
+export OTEL_EXPORTER_OTLP_ENDPOINT=http://jaeger-collector:4318
+./bin/magic serve
+```
+
+MagiC propagates W3C Trace Context headers (`traceparent`) across all task dispatches. You'll see the full call graph from API → Router → Dispatcher → Worker.
+
+---
+
+## What You Just Built
+
+```
+Your App (curl / SDK)
+    │
+    ├─→ MagiC Gateway (auth, cost, policy)
+    │
+    ├─→ Worker Registry (track capabilities)
+    │
+    ├─→ Router (find best worker)
+    │
+    ├─→ Dispatcher (HTTP to workers)
+    │       ├─→ CrewAI Agent
+    │       └─→ LangChain Agent
+    │
+    ├─→ Cost Controller (budget tracking)
+    │
+    ├─→ Audit Log (who ran what)
+    │
+    └─→ PostgreSQL (persistence)
+
+Multi-tenant? Yes. Auth? Yes. Observability? Yes.
+```
+
+---
+
+## Next Steps
+
+**Scale to 10 workers:**
+- Spin up more worker instances (Python, Go, Node — any language with HTTP)
+- MagiC's router automatically load-balances across them
+- Cost tracking aggregates per worker and per organization
+
+**Add RBAC and policies:**
+- See `docs-site/guide/rbac.md` for role definitions
+- See `docs-site/guide/policies.md` for guardrails (blocked topics, max cost per task, etc.)
+
+**Wrap your existing agent:**
+- Follow `examples/integrations/crewai/` or `examples/integrations/langchain/`
+- No changes to your agent code needed
+
+**Publish a worker plugin:**
+- Follow the worker token standard in `docs-site/api/reference.md`
+- Share it on GitHub with topic `magic-worker`
+
+---
+
+## Troubleshooting
+
+**"Connection refused on localhost:8080"**
+- MagiC didn't start. Check `./bin/magic serve` output for errors.
+- Port 8080 in use? Set `export MAGIC_PORT=8000` and try again.
+
+**"worker registered but task fails with 'no matching worker'"**
+- Check `/api/v1/workers` — is your worker listed?
+- Check the task's `required_capabilities` matches what the worker declares.
+- Check worker logs for registration errors.
+
+**"database 'magic' does not exist"**
+- PostgreSQL isn't running, or connection URL is wrong.
+- Verify: `psql "$MAGIC_POSTGRES_URL" -c "SELECT 1"`
+
+**"MAGIC_API_KEY: minimum 32 characters"**
+- Generate a new one: `openssl rand -hex 32`
+
+**"migrations failed: pgvector extension not installed"**
+- Use a Postgres image with pgvector: `postgres:15-pgvector`

+# Integration Examples — Make Your Existing Agents MagiC Workers
+
+> **MagiC doesn't replace your agent framework. It manages the fleet around it.**
+
+Already have a CrewAI crew, a LangChain agent, or an AutoGen GroupChat that
+works? Don't rewrite it. Wrap it. In ~5 lines you get cost tracking, budget
+caps, RBAC, retries, policy enforcement, audit logs, and Prometheus metrics —
+without touching the agent logic you already trust.
+
+## Examples in this folder
+
+| Framework | Example | What you get |
+|---|---|---|
+| [CrewAI](./crewai) | 2-agent crew (researcher + writer) wrapped as one capability `research_and_write` | Cost tracking, RBAC, audit, retries for CrewAI kickoffs |
+| [LangChain](./langchain) | Tool-calling agent (calculator + DuckDuckGo) as capability `qa_with_tools` | Retry + circuit breaker on flaky LLM calls, per-task cost cap, tool-use metrics |
+| [AutoGen](./autogen) | 3-agent GroupChat (PM → Engineer → Critic) as capability `product_spec_review` | Timeout on runaway debates, budget protection, clean single-capability interface |
+| [LlamaIndex](./llamaindex) | `VectorStoreIndex` RAG query engine as capability `rag_query` | Per-query cost tracking (LLM + embeddings), budget caps, SSE streaming, fallback workers |
+| [Haystack](./haystack) | 4-stage QA pipeline (embed → retrieve → prompt → generate) as capability `qa_pipeline` | Enterprise observability around production Haystack pipelines — not just a POC |
+| [DSPy](./dspy) | `ChainOfThought` intent classifier as capability `classify_intent` | A/B testing of compiled variants, per-variant cost tracking, router-level routing strategies |
+
+## The wrapper pattern
+
+Every integration follows the same shape — because there's really only one
+shape to follow:
+
+```python
+from magic_ai_sdk import Worker
+
+# 1. Build your existing agent however you already do.
+my_agent = build_my_existing_agent()
+
+# 2. Create a MagiC worker.
+worker = Worker(name="MyBot", endpoint="http://localhost:9100")
+
+# 3. Expose agent invocations as capabilities.
+@worker.capability("do_the_thing", description="What this does")
+def do_the_thing(**inputs) -> dict:
+    result = my_agent.run(**inputs)   # <-- your framework, unchanged
+    return {"result": result}
+
+# 4. Register + serve.
+worker.run("http://localhost:8080", port=9100)
+```
+
+That is the whole concept. Every file under this directory is a concrete
+version of that skeleton.
+
+## When to use MagiC
+
+**Good fit:**
+- You have **multiple agents** and need routing, fallback, fleet health.
+- You care about **cost and budgets** — per-task, per-team, per-day.
+- You need **RBAC, audit, policy** for enterprise / regulated environments.
+- You want **observability** (Prometheus, structured logs) without bolting it on per project.
+- You want **orchestration** — chaining capabilities from different frameworks in one workflow DAG.
+
+**Probably overkill:**
+- A single script with one agent run — just run the script.
+- Pure experimentation — stay in a notebook.
+- Agents that don't hit external APIs (no cost, nothing to govern).
+
+## Prerequisites (all examples)
+
+1. MagiC gateway running locally:
+   ```bash
+   cd core && go build ./cmd/magic && ./magic serve
+   ```
+2. Python 3.11+ and a virtualenv per example (each has its own deps).
+3. An LLM provider — OpenAI by default, Ollama works offline (each `.env.example`
+   documents both).
+
+## Contribute
+
+Have a framework not listed here? **Send a PR.**
+
+Already covered: CrewAI, LangChain, AutoGen, LlamaIndex, Haystack, DSPy.
+
+Good candidates next:
+- **Smolagents** — expose a code-executing agent under a safety-constrained capability.
+- **Semantic Kernel** — wrap a Microsoft Semantic Kernel planner as a capability.
+- **AWS Bedrock Agents** — expose a managed Bedrock agent behind the same MagiC fleet controls.
+- **Plain FastAPI / Flask agents** — wrap an internal microservice you already run.
+
+Checklist for a new example:
+- Self-contained `examples/integrations/<framework>/` folder.
+- `main.py` (~100 lines), `requirements.txt`, `.env.example`, `README.md`.
+- Same README structure as the existing three (Why it matters / Architecture /
+  Run / What you get / Local-only mode / Pattern).
+- Runnable against a fresh `magic serve` on localhost.
+- OpenAI default, Ollama fallback documented.
+- No hardcoded secrets.

+# AutoGen + MagiC
+
+Expose a multi-agent **AutoGen** GroupChat as a single MagiC worker capability.
+
+## Why it matters
+
+AutoGen shines at multi-agent conversations: PMs debating engineers, critics
+stress-testing specs, solvers arguing their way to a plan. But to the *caller*,
+that internal debate is noise. MagiC lets you hide a 3-agent GroupChat behind
+one clean capability — `product_spec_review(feature_idea)` — and exposes only
+the final artifact (`spec` + a trimmed `discussion_summary`).
+
+**Multi-agent complexity inside, one clean interface outside.** That is the
+contract MagiC makes possible.
+
+## Architecture
+
+```

+```
+
+## Run
+
+### 1. Install
+
+```bash
+cd examples/integrations/autogen
+python -m venv .venv && source .venv/bin/activate
+pip install -r requirements.txt
+```
+
+### 2. Configure
+
+```bash
+cp .env.example .env
+# edit .env — set OPENAI_API_KEY, or switch to Ollama
+```
+
+### 3. Start MagiC gateway
+
+```bash
+cd core
+go build ./cmd/magic
+./magic serve       # :8080
+```
+
+### 4. Run the worker
+
+```bash
+python main.py      # registers with MagiC and serves on :9103
+```
+
+### 5. Submit a task
+
+```bash
+curl -X POST http://localhost:8080/api/v1/tasks \
+  -H 'Content-Type: application/json' \
+  -d '{
+    "type": "product_spec_review",
+    "input": {"feature_idea": "A dashboard that shows AI-worker cost per team in real time"},
+    "routing": {"required_capabilities": ["product_spec_review"]},
+    "contract": {"timeout_ms": 180000, "max_cost": 1.50}
+  }'
+```
+
+Response shape:
+
+```json
+{
+  "status": "done",
+  "output": {
+    "spec": "Problem statement: ...\nUser stories: ...\nMetrics: ...",
+    "discussion_summary": "[product_manager]: ...\n\n[engineer]: ...\n\n[critic]: ...",
+    "rounds_limit": 5
+  }
+}
+```
+
+## What you get (for free)
+
+| Feature | Provided by MagiC |
+|---|---|
+| Hard timeout on runaway GroupChats | Gateway contract |
+| Per-task `max_cost` (caps LLM spend on a debate) | CostCtrl |
+| Budget alerts when the team blows their monthly cap | CostCtrl |
+| RBAC — only PM role can run spec reviews | OrgMgr |
+| Audit log of every spec produced | Audit |
+| Retry on transient failures | Router |
+| Prometheus metrics on GroupChat runtime | Monitor |
+
+## Local-only mode
+
+Use Ollama — AutoGen honours `base_url`:
+
+```env
+OPENAI_API_KEY=ollama
+OPENAI_API_BASE=http://localhost:11434/v1
+AUTOGEN_LLM_MODEL=llama3.2
+```
+
+Group chats with weaker local models tend to ramble; keep `AUTOGEN_MAX_ROUNDS`
+small (3–4) and temperature low.
+
+## Pattern
+
+```python
+from magic_ai_sdk import Worker
+import autogen  # your existing agents
+
+worker = Worker(name="MyAutoGen", endpoint="http://localhost:9103")
+
+@worker.capability("product_spec_review")
+def product_spec_review(feature_idea: str) -> dict:
+    group = build_my_group_chat()        # <-- unchanged
+    manager = autogen.GroupChatManager(groupchat=group, llm_config=cfg)
+    user_proxy.initiate_chat(manager, message=feature_idea)
+    return {"spec": summarize(group.messages)}
+
+worker.run("http://localhost:8080", port=9103)
+```
+
+One decorator. Multi-agent system inside; single capability outside.

+# CrewAI + MagiC
+
+Wrap an existing **CrewAI** crew as a MagiC worker — no rewrite, no glue code.
+
+## Why it matters
+
+You already have a CrewAI crew that works. You don't want to rewrite it just
+to get production niceties. Drop it inside a `@worker.capability` handler and
+MagiC's orchestrator now manages it — cost tracking, budget enforcement,
+RBAC, policy controls, retries, audit logs — without touching any agent logic.
+
+Your crew stays a crew. MagiC is the fleet manager around it.
+
+## Architecture

+## What you get (for free)
+
+| Feature | Provided by MagiC |
+|---|---|
+| Automatic retry on worker crash | Registry + router |
+| Per-task cost tracking | CostCtrl |
+| Daily / monthly budget caps | CostCtrl |
+| RBAC (who can submit which task type) | OrgMgr |
+| Policy engine (block dangerous topics, etc.) | Gateway middleware |
+| Audit log (who ran what, when, output) | Audit |
+| Fallback worker on failure | Router |
+| Prometheus metrics on every run | Monitor |
+
+## Local-only mode (no OpenAI bill)
+
+Install Ollama, pull `llama3.2`, and set:
+
+```env
+OPENAI_API_KEY=ollama
+OPENAI_API_BASE=http://localhost:11434/v1
+CREWAI_LLM_MODEL=ollama/llama3.2
+```
+
+Everything else stays the same.
+
+## Pattern
+
+The pattern is small enough to memorise:
+
+```python
+from magic_ai_sdk import Worker
+from crewai import Crew  # your existing crew
+
+worker = Worker(name="MyCrew", endpoint="http://localhost:9101")
+
+@worker.capability("my_crew_run")
+def run_crew(**kwargs) -> dict:
+    crew = build_my_existing_crew()      # <-- your code, unchanged
+    result = crew.kickoff(inputs=kwargs)
+    return {"result": str(result)}
+
+worker.run("http://localhost:8080", port=9101)
+```
+
+That is the whole integration.

+# DSPy + MagiC
+
+Expose a **DSPy** program — zero-shot or compiled — as a MagiC worker
+capability. Versioned prompts, A/B testing, and cost tracking per variant,
+without wiring any infra yourself.
+
+## Why it matters
+
+DSPy treats prompts as code you compile, not strings you hand-tune. That
+model is powerful, but it raises a deployment question: once you have
+three compiled variants of the same program, how do you route traffic
+between them, measure cost per variant, and roll back if the new one
+regresses?
+
+MagiC answers that at the fleet layer. Register each DSPy program (or
+each compiled variant) as a worker with capability `classify_intent`,
+and the router picks one by `best_match` / `round_robin` / `cheapest`.
+CostCtrl already tracks spend per worker — so you get per-variant
+economics for free. Audit logs capture every prediction.
+
+**DSPy compiles the program. MagiC ships it, versions it, and measures it.**
+
+## Architecture
+
+```
+    client (curl / SDK)
+            │
+            │  POST /api/v1/tasks  type=classify_intent
+            ▼
+    ┌────────────────────┐
+    │   MagiC Gateway    │  auth, cost cap, policy
+    └─────────┬──────────┘
+              │  router picks variant (best_match / round_robin / cheapest)
+              ▼
+    ┌────────────────────────────────┐
+    │   DSPyWorker (this file)       │
+    │                                │
+    │   IntentClassifier(dspy.Module)│
+    │   └─ ChainOfThought            │
+    │       └─ ClassifyIntent sig    │
+    └────────────────────────────────┘
+```
+
+Run a second instance of this worker with a compiled program (e.g.
+`BootstrapFewShot`) and the same capability name — MagiC will route
+between them. Compare cost and quality from the metrics endpoint.
+
+## Run
+
+### 1. Set up a virtualenv and install deps
+
+```bash
+cd examples/integrations/dspy
+python -m venv .venv && source .venv/bin/activate
+pip install -r requirements.txt
+```
+
+### 2. Configure environment
+
+```bash
+cp .env.example .env
+# edit .env — set OPENAI_API_KEY, or switch to Ollama (see .env.example)
+```
+
+### 3. Start MagiC gateway (in another terminal)
+
+```bash
+cd core
+go build ./cmd/magic
+./magic serve         # listens on :8080
+```
+
+### 4. Run the worker
+
+```bash
+python main.py
+# → registers with MagiC and serves on :9106
+```
+
+### 5. Submit a task
+
+```bash
+curl -X POST http://localhost:8080/api/v1/tasks \
+  -H 'Content-Type: application/json' \
+  -d '{
+    "type": "classify_intent",
+    "input": {"text": "I love how fast this framework is — shipped on Friday."},
+    "routing": {"required_capabilities": ["classify_intent"]},
+    "contract": {"timeout_ms": 30000, "max_cost": 0.05}
+  }'
+```
+
+Response shape:
+
+```json
+{
+  "status": "done",
+  "output": {
+    "label": "positive",
+    "reasoning": "The text expresses enthusiasm about speed and shipping.",
+    "model": "openai/gpt-4o-mini"
+  }
+}
+```
+
+## What you get (for free)
+
+| Feature | Provided by MagiC |
+|---|---|
+| Per-variant cost tracking (A vs B compiled program) | CostCtrl |
+| Router strategies for A/B (round_robin, cheapest, best_match) | Router |
+| Budget caps per team per day | CostCtrl |
+| RBAC on who can hit the classifier | OrgMgr |
+| Audit log of every classification | Audit |
+| Retry on transient LLM errors | Router |
+| Prometheus metrics per DSPy program variant | Monitor |
+
+## Local-only mode (no OpenAI bill)
+
+DSPy routes through LiteLLM under the hood, so Ollama works with one
+env tweak:
+
+```env
+OPENAI_API_KEY=ollama
+OPENAI_API_BASE=http://localhost:11434/v1
+DSPY_LLM_MODEL=ollama_chat/llama3.2
+```
+
+Smaller local models may ignore the label constraint; the handler
+normalises any out-of-set output to `neutral` defensively.
+
+## Upgrading to a compiled variant
+
+Inside `_program_singleton()`:
+
+```python
+from dspy.teleprompt import BootstrapFewShot
+trainset = [dspy.Example(text="...", label="positive", reasoning="...").with_inputs("text"), ...]
+_program = BootstrapFewShot(metric=my_metric).compile(IntentClassifier(), trainset=trainset)
+```
+
+Ship that worker side-by-side with the zero-shot one on the same
+capability name and let MagiC route between them.
+
+## Pattern
+
+```python
+from magic_ai_sdk import Worker
+import dspy
+
+dspy.configure(lm=dspy.LM(model="openai/gpt-4o-mini"))
+program = MyDspyProgram()                     # <-- your existing program
+
+worker = Worker(name="MyDSPy", endpoint="http://localhost:9106")
+
+@worker.capability("my_dspy_task")
+def run(**inputs) -> dict:
+    pred = program(**inputs)
+    return {"label": pred.label, "reasoning": pred.reasoning}
+
+worker.run("http://localhost:8080", port=9106)
+```
+
+That is the whole integration.
+
+## Disclaimer
+
+DSPy is still iterating quickly; `dspy.configure`, `dspy.LM`, and
+`dspy.Signature` all landed in 2.5 and minor releases can rename
+fields. If the example fails to import, pin `dspy-ai>=2.5,<2.7`.

+# Haystack + MagiC
+
+Wrap a production **Haystack 2.x** pipeline as a MagiC worker — keep the
+pipeline graph, gain enterprise fleet controls.
+
+## Why it matters
+
+Haystack is built for production RAG: typed components, explicit DAG,
+serialisable pipelines. Teams ship it to customers and live with it for
+years. What Haystack does **not** own is the layer *around* the pipeline
+— who's allowed to call it, what each call costs, which team's monthly
+budget just blew up, whether the embedder has started returning 500s.
+
+Drop your `Pipeline` into a `@worker.capability` handler and MagiC
+adds cost tracking, budget caps, retries, RBAC, audit logs, and
+Prometheus metrics on top.
+
+**Haystack runs production pipelines. MagiC runs the production around
+them — enterprise observability, not just a POC.**

+# LangChain + MagiC
+
+Expose a **LangChain** tool-calling agent as a MagiC worker capability.
+
+## Why it matters
+
+LangChain is fantastic for composing agents and tools, but on its own it
+doesn't give you production scaffolding: retries on flaky LLM calls, per-tenant
+cost caps, budget alerts, RBAC, or a circuit breaker when your OpenAI quota
+burns. MagiC wraps all that around the agent you already wrote. Your
+`AgentExecutor` is the same; the surrounding infrastructure is just better.
+
+LangChain agents + MagiC orchestration = a production deployment path.
+
+## Architecture
+
+```
+    client (curl / SDK / another worker)
+            │
+            │  POST /api/v1/tasks  type=qa_with_tools
+            ▼
+    ┌────────────────────┐
+    │   MagiC Gateway    │  retry, circuit break, cost limit

+    │   ChatOpenAI(gpt-4o-mini)       │
+    └─────────────────────────────────┘
+```
+
+## Run
+
+### 1. Install
+
+```bash
+cd examples/integrations/langchain
+python -m venv .venv && source .venv/bin/activate
+pip install -r requirements.txt
+```
+
+### 2. Configure
+
+```bash
+cp .env.example .env
+# edit .env — set OPENAI_API_KEY, or switch to Ollama
+```
+
+### 3. Start MagiC gateway
+
+```bash
+cd core
+go build ./cmd/magic
+./magic serve       # :8080
+```
+
+### 4. Run the worker
+
+```bash
+python main.py      # registers with MagiC and serves on :9102
+```
+
+### 5. Submit a task
+
+```bash
+curl -X POST http://localhost:8080/api/v1/tasks \
+  -H 'Content-Type: application/json' \
+  -d '{
+    "type": "qa_with_tools",
+    "input": {"question": "What is 17 * 23, and what is the capital of Vietnam?"},
+    "routing": {"required_capabilities": ["qa_with_tools"]},
+    "contract": {"timeout_ms": 60000, "max_cost": 0.50}
+  }'
+```
+
+Expected response shape:
+
+```json
+{
+  "id": "tsk_...",
+  "status": "done",
+  "output": {
+    "answer": "17 * 23 = 391. The capital of Vietnam is Hanoi.",
+    "steps": [
+      {"tool": "calculator", "input": {"expression": "17 * 23"}, "output": "391"},
+      {"tool": "web_search", "input": {"query": "capital of Vietnam"}, "output": "..."}
+    ]
+  }
+}
+```
+
+## What you get (for free)
+
+| Feature | Provided by MagiC |
+|---|---|
+| Retry on 5xx from LLM provider | Router |
+| Circuit breaker when worker crashes repeatedly | Registry |
+| Per-task `max_cost` enforcement | CostCtrl |
+| Daily cost cap per worker | CostCtrl |
+| RBAC on who can call `qa_with_tools` | OrgMgr |
+| Audit trail of every question and answer | Audit |
+| Prometheus metrics on tool-use patterns | Monitor |
+
+## Local-only mode
+
+Use Ollama:
+
+```env
+OPENAI_API_KEY=ollama
+OPENAI_API_BASE=http://localhost:11434/v1
+LANGCHAIN_LLM_MODEL=llama3.2
+```
+
+Note: tool-calling quality varies by local model. `llama3.2` and `qwen2.5`
+handle function calls reasonably; small models struggle.
+
+## Pattern
+
+```python
+from magic_ai_sdk import Worker
+from langchain.agents import AgentExecutor  # your existing executor
+
+worker = Worker(name="MyLCWorker", endpoint="http://localhost:9102")
+executor = build_my_agent_executor()         # <-- unchanged
+
+@worker.capability("qa_with_tools")
+def qa_with_tools(question: str) -> dict:
+    result = executor.invoke({"input": question})
+    return {"answer": result["output"]}
+
+worker.run("http://localhost:8080", port=9102)
+```
+
+The entire integration is one decorator and one call.

+# LlamaIndex + MagiC
+
+Wrap an existing **LlamaIndex** RAG query engine as a MagiC worker — no
+rewrite, no retrieval-glue duplication.
+
+## Why it matters
+
+LlamaIndex gives you best-in-class retrieval and response synthesis. What
+it does not give you is fleet management: who is allowed to query, what
+each query costs, which team's budget it hits, whether the retriever has
+silently broken in production.
+
+Drop your query engine into a `@worker.capability` handler and MagiC adds
+cost tracking, budget caps, retries, RBAC, audit logs, and Prometheus
+metrics — without touching your index pipeline.
+
+**LlamaIndex retrieves. MagiC governs.**
+
+## Architecture
+

+## Run
+
+### 1. Set up a virtualenv and install deps
+
+```bash
+cd examples/integrations/llamaindex
+python -m venv .venv && source .venv/bin/activate
+pip install -r requirements.txt
+```
+
+### 2. Configure environment
+
+```bash

+# edit .env — set OPENAI_API_KEY, or switch to local models (see .env.example)
+```
+
+### 3. Start MagiC gateway (in another terminal)
+
+```bash
+cd core
+go build ./cmd/magic
+./magic serve         # listens on :8080
+```
+
+### 4. Run the worker
+
+```bash
+python main.py
+# → registers with MagiC and serves on :9104
+```
+
+### 5. Submit a task
+
+```bash
+curl -X POST http://localhost:8080/api/v1/tasks \
+  -H 'Content-Type: application/json' \
+  -d '{
+    "type": "rag_query",
+    "input": {"query": "How does MagiC handle budgets?", "top_k": 3},
+    "routing": {"required_capabilities": ["rag_query"]},
+    "contract": {"timeout_ms": 60000, "max_cost": 0.25}
+  }'
+```
+
+Response shape:
+
+```json
+{
+  "status": "done",
+  "output": {
+    "answer": "...",
+    "sources": ["...", "..."],
+    "top_k": 3
+  }
+}
+```
+
+## What you get (for free)
+
+| Feature | Provided by MagiC |
+|---|---|
+| Per-query cost tracking (LLM + embeddings) | CostCtrl |
+| Daily / monthly budget caps per team | CostCtrl |
+| RBAC — who can hit which knowledge base | OrgMgr |
+| Automatic retry on flaky embedding APIs | Router |
+| Audit log of every query + answer | Audit |
+| Fallback worker on failure | Router |
+| Prometheus metrics on query latency | Monitor |
+| SSE streaming of long-running queries | Gateway |
+
+## Local-only mode (no OpenAI bill)
+
+LlamaIndex supports Ollama via the community package:
+
+```bash
+pip install llama-index-llms-ollama llama-index-embeddings-ollama
+```
+
+Then edit `main.py` to swap `OpenAI` / `OpenAIEmbedding` for their Ollama
+equivalents. See the `llama_index.llms.ollama` docs for the exact class
+names (they track fast). Example stubs:
+
+```python
+from llama_index.llms.ollama import Ollama
+from llama_index.embeddings.ollama import OllamaEmbedding
+Settings.llm = Ollama(model="llama3.2", request_timeout=60.0)
+Settings.embed_model = OllamaEmbedding(model_name="nomic-embed-text")
+```
+
+## Pattern
+
+```python
+from magic_ai_sdk import Worker
+from llama_index.core import VectorStoreIndex, Document
+
+worker = Worker(name="MyRAG", endpoint="http://localhost:9104")
+index = VectorStoreIndex.from_documents([Document(text=t) for t in my_docs])
+
+@worker.capability("rag_query")
+def rag_query(query: str, top_k: int = 3) -> dict:
+    engine = index.as_query_engine(similarity_top_k=top_k)   # <-- your logic
+    response = engine.query(query)
+    return {"answer": str(response),
+            "sources": [str(n.node.get_content()) for n in response.source_nodes]}
+
+worker.run("http://localhost:8080", port=9104)
+```
+
+That is the whole integration.
+
+## Disclaimer
+
+LlamaIndex's Python API has been evolving quickly; class paths
+(`llama_index.core` vs `llama_index.llms.openai`) can drift between
+minor releases. If an import fails, pin `llama-index>=0.12,<0.13` or
+check the official release notes for the version you installed.

+Wraps a LlamaIndex RAG query engine (VectorStoreIndex over a small in-memory
+document set) as a MagiC worker capability. LlamaIndex owns retrieval and
+synthesis; MagiC owns routing, cost tracking, budgets, RBAC, and audit.
+
+Usage::
+
+    cp .env.example .env              # fill in OPENAI_API_KEY
+    pip install -r requirements.txt
+    # in another terminal: cd core && go build ./cmd/magic && ./magic serve
+    python main.py
