 # Changelog
 
+## 0.43.0 — 2026-07-14 (release candidate)
+
+### Added
+
+- Schema v22 memory-to-memory graph edges with canonical symmetric storage,
+  provenance, transactional inference, reverse traversal, and graph-RAG
+  regression coverage.
+- Schema v23 development/holdout RAG cases and schema v24 bitemporal evidence
+  observations, including valid-time/knowledge-time graph queries and Git
+  branch, commit, and worktree provenance through CLI and MCP.
+- Schema v28 evidence-backed causal observation kinds (`causes`, `depends_on`,
+  `blocks`, `enables`, and `prevents`) with temporal graph coverage.
+- A typed memory domain and application boundary shared by CLI, MCP, and HTTP,
+  with centralized type, scope, status, confidence, sensitivity, and link
+  invariants.
+- A 45-operation catalog generated from one Rust definition and exposed through
+  `dukememory operations`, MCP `memory_operations`, HTTP `/operations`, and
+  checked-in Markdown.
+- Absolute p95/QPS vector-search gates, a 4096-vector CI benchmark, and
+  dedicated migration, verified backup/restore, cross-surface compatibility,
+  domain-boundary, and supply-chain suites.
+- CycloneDX 1.5 SBOM generation and release artifacts, immutable GitHub Action
+  pins, and tests that reject mutable action references.
+- MCP 2025-11-25 lifecycle/framing support, capability-scoped project selection,
+  typed tool results, and bounded malformed-frame coverage.
+- MCP core/standard/full profiles, cursor pagination, Resources, optional Tasks,
+  cached strict Draft 2020-12 tool schemas, and runtime argument validation.
+- A dual MCP protocol path for the stable 2025 lifecycle and the locked
+  `2026-07-28` stateless release candidate, including `server/discover` and the
+  per-request `io.modelcontextprotocol/tasks` extension.
+- Schema v25 durable MCP task records with client/lifecycle isolation,
+  restart-safe terminal results, TTL failure handling, and cooperative
+  cancellation intent.
+- Property-based HTTP and MCP framing coverage over arbitrary byte input,
+  canonical lengths, and duplicate singleton headers.
+- A deterministic `eval advanced` capability report across CLI, MCP, and HTTP
+  for explicit causal paths, retrieval-poisoning signals, global graph
+  coverage, and bitemporal consistency.
+- RAG Eval v5 expected-rank, Hit@1/3/5, and MRR metrics; structure-aware source
+  chunking and content-hashed evidence provenance.
+- macOS/Windows core CI and Sigstore build-provenance attestations for final
+  release archives, checksums, and SBOMs.
+- Byte-based storage quotas with warn/critical pressure, quota-aware backup
+  rotation, HTTP request correlation ids, and Linux ARM64/musl plus Windows
+  release targets.
+
+### Changed
+
+- HTTP requests open one selected project database, process-local schema
+  initialization is cached, and versioned migrations run transactionally with
+  structural schema verification.
+- Retrieval policy is loaded once per operation from the selected project;
+  ranking, core memory HTTP routes, graph storage/inference, and compatibility
+  tests now live in focused modules.
+- Local ML dependencies are feature-gated, built-in model revisions and hashes
+  are pinned, ONNX output access is checked, and vector dimensions come from
+  model output instead of a hard-coded constant.
+- `age` is upgraded from 0.11.4 to 0.12.1; remaining unmaintained build-time
+  transitive exceptions are documented with explicit upstream removal gates.
+- The stable operation catalog now declares stability, authorization,
+  idempotency, destructive/open-world effects, and schema identifiers; MCP
+  annotations for catalogued tools are derived from it.
+- Trusted OAuth gateways now enforce catalog-derived `memory:read`,
+  `memory:write`, `memory:maintenance`, and `memory:filesystem` scopes across
+  HTTP and MCP, and operation discovery exposes the exact required scope.
+- MCP framing and HTTP file-ingest routing now live in focused modules with
+  independent boundary tests.
+- Legacy `tasks/result` waits are bounded; 2026 task creation is server-directed
+  and limited to effectively read-only calls. Model generation runs in bounded
+  workers and observes cooperative MCP cancellation while network work remains
+  capped by its configured timeout.
+- RAG and graph-RAG reject generated prompt-injection markers even when the
+  output cites selected evidence, and a versioned generated-output fixture is
+  enforced alongside the pre-retrieval poisoning fixture.
+- `rag-refresh --prune-missing` previews and explicitly removes dead indexed
+  source rows together with their cascading chunks and embeddings.
+- Secret detection now shares structured provider, credential URL, auth header,
+  JWT, private-key, and adjacent-assignment rules across admission, scanning,
+  and redaction while recognizing explicit placeholders.
+- The local UI serves CSS and JavaScript as same-origin assets under a strict
+  CSP without `unsafe-inline` or inline style/script attributes.
+- RAG Eval v6 now separates development and holdout results, requires a minimum
+  reviewed holdout set for release readiness, and fingerprints the eval corpus
+  and retrieval configuration in baseline v3.
+- RAG Eval v7 explicitly separates retrieval ranking, deterministic extractive
+  grounding, and synthetic generated-output guard evaluation, and fingerprints
+  development and holdout partitions independently without claiming that
+  holdout source origin or live-model quality was automatically verified.
+- Durable MCP task handling and release-gate v3 composition now live in focused
+  submodules, and the late CLI compatibility surfaces have been split out of
+  the historical monolithic integration test source.
+- Lightweight web RAG evaluation summaries now live outside the 19k-line
+  observability aggregate; CI lowers that file's growth ceiling and freezes the
+  reviewed 22 direct/5 optional runtime dependency budget.
+- Coverage, every fuzz target, and CodeQL now terminate in stable sentinel jobs
+  on pull requests and merge groups; the protected branch can require those
+  sentinels together with the existing CI and supply-chain aggregators.
+- The bounded native OTLP/HTTP JSON exporter now emits access logs, server
+  spans, and HTTP request count/duration metrics; optional telemetry identifier
+  hashing or omission protects peer/client addresses before local or remote
+  emission.
+
+### Fixed
+
+- Prevent invalid memory values and sensitive updates from bypassing domain
+  validation through individual transport adapters.
+- Prevent graph edge duplication, one-way symmetric traversal, and partial
+  graph inference writes.
+- Return stable client/server HTTP status classes with security headers, and
+  preserve core CRUD behavior after routing decomposition.
+- Keep MCP and HTTP file/DB selection inside allowed project capabilities,
+  default maintenance endpoints to preview, and return opaque incident ids for
+  unexpected HTTP failures.
+- Enforce private Unix permissions on SQLite databases/WAL/SHM and enable
+  `secure_delete=FAST` without claiming application-level database encryption.
+- Preserve v21 data, leased-session event sequences, graph edges, and schema
+  integrity across v22-v24 migrations plus strict verified backup/restore.
+- Create indexes that depend on v23/v24 columns only after legacy tables have
+  been migrated, so real v22 databases upgrade without bootstrap SQL failures.
+- Block redirect/DNS-rebinding SSRF paths for model/provider egress and reject
+  transfer-encoding ambiguity, duplicate content lengths, folded headers, and
+  oversized HTTP bodies before allocation.
+- Preserve the highest-scoring endpoint/command literals in tight RAG chunk
+  summaries instead of dropping the entire literal suffix when all candidates
+  cannot fit.
+
+## 0.42.0 — 2026-07-14 (local development)
+
+### Added
+
+- A stable `ControlSnapshot` schema shared by CLI, MCP `memory_status`, HTTP,
+  and the initial web UI, with one normalized health, quality, recall,
+  autonomy, session, and optional-runner summary.
+- Revision-aware in-process snapshot caching with bounded TTL/entry count,
+  cache hit/age/compute telemetry, concurrent-request coverage, and automatic
+  invalidation after relevant SQLite or control-file changes.
+- Filtered, bounded evidence-session pages by status and outcome, explicit
+  derived attempt states, and per-status retention policy defaults in
+  `.agent/config.toml`.
+- Dedicated control-plane integration coverage outside the historical
+  monolithic CLI compatibility test file.
+- RAG source packing promotes strong chunks from new files over weaker memory
+  cards when the selected pack is memory-heavy and already at its limit.
+- Legacy autonomous status snapshots with older embedded quality-report fields
+  are normalized on read instead of blocking status, ops, or control surfaces.
+- RAG Eval v2 now reports `evidence_placement` with selection recall,
+  candidate recall, near-miss count, and suppression reasons.
+- RAG Eval v3 now adds `eval_matrix` coverage dimensions and
+  `retrieval_tuning` profile recommendations derived from eval near-misses,
+  missing candidates, and semantic fallbacks.
+- `project-diff` and `memory-diff-review` now include compact impact summaries
+  with affected memory ids, unlinked changed files, severity, and suggested
+  action.
+- `graph-rag` now returns `graph_summary` with seed/expanded nodes, edge
+  density, isolated nodes, relationship coverage, max relationships per node,
+  and relationship kind counts.
+- The stable `web-control-center` snapshot now includes `rag_eval` and
+  `diff_impact` panels while keeping unconfigured RAG eval cheap.
+- The stable `web-control-center` and V12 detail panels now surface RAG eval
+  matrix coverage and retrieval tuning status/profile.
+- `autonomous-supervisor` now reports a `readiness` block for RAG eval and
+  diff-impact pressure before apply, including eval matrix and retrieval tuning
+  readiness.
+
+### Changed
+
+- `web-control-center` is now the canonical stable surface; V3 through V12
+  commands are hidden compatibility aliases, while legacy V12 detail remains
+  opt-in through `--details` or `?view=details`.
+- The web UI loads detailed diagnostics with one stable request instead of a
+  large parallel fan-out across every historical endpoint.
+- `auto-ranking-tune` now considers RAG eval retrieval tuning when stored eval
+  cases show evidence selection pressure.
+- Agent-session cleanup can safely select completed, failed, partial, and
+  abandoned states while remaining dry-run-first and transactionally deleting
+  child lifecycle events only after explicit `--apply`.
+- Control snapshot and session operations live in focused modules rather than
+  adding more routing and lifecycle logic to existing monoliths.
+
+### Fixed
+
+- Prevent repeated control requests from recomputing identical expensive
+  diagnostics while still invalidating immediately after durable changes.
+- Prevent optional runner or remote-sync readiness from blocking local memory
+  readiness in the stable control result.
+- Prevent unbounded session history reads and one-size-fits-all cleanup windows
+  for unsuccessful or abandoned work.
+- Prevent stale autonomous status JSON from failing after quality-report schema
+  additions such as `age_days`, `classification`, or `actionable_count`.
+
+## 0.41.0 — 2026-07-14 (local development)
+
+### Added
+
+- Recall benchmark v2 resolves historical read ids through explicit
+  supersession chains, probes the exact active successor, records stable probe
+  identities in baselines, and reports changed probe sets as stale instead of
+  false regressions.
+- Quality Score v2 classifies cards as healthy, fresh, dormant, stale,
+  obsolete, noisy, oversized, or needing evidence, with separate evidence and
+  recommended-action fields plus aggregate actionable counts.
+- Evidence-session observability for lease contention, orphaned attempts,
+  recovery latency, and stale heartbeats, plus dry-run-first completed-session
+  retention over CLI, MCP, HTTP, and the local web UI.
+- Explicit required local-autonomy checks and optional sync checks, with
+  independent readiness, issues, and recommendations.
+
+### Changed
+
+- The stable web control snapshot now returns the small health, quality,
+  recall, local-autonomy, runner, and session summary needed by the initial UI;
+  the full diagnostic surface remains lazy and opt-in.
+- Ordinary unused durable cards are treated as dormant history rather than
+  automatic quality debt; actionable scoring is reserved for evidence-backed
+  stale, obsolete, noisy, oversized, or unlinked conditions.
+- The local autonomy result is no longer blocked by an unconfigured remote
+  target; encrypted remote/VDS sync remains an optional readiness dimension.
+
+### Fixed
+
+- Prevent historical superseded cards in read telemetry from lowering recall
+  benchmarks when the active successor is retrievable.
+- Prevent changed benchmark probe sets from being compared as if they were the
+  same baseline population.
+- Prevent missing file links retained only by superseded/rejected history from
+  polluting active drift and autonomy readiness; explicit per-card link
+  inspection still preserves the historical evidence.
+- Prevent completed evidence sessions from accumulating without a bounded,
+  reviewable, reversible-by-backup retention workflow.
+
+## 0.40.0 — 2026-07-14 (local development)
+
+### Added
+
+- Schema v21 leased agent sessions with atomic `claim`, `renew`, `release`,
+  and stale-session recovery, including per-attempt owner fencing, opaque lease
+  tokens, expiry timestamps, heartbeat state, and attempt counters.
+- Retry-safe lifecycle events with caller-provided `event_id`, monotonic
+  per-session sequences, attempt attribution, exact-retry acceptance, and
+  conflicting-payload rejection.
+- Agent-session trace v2 metrics for duration, attempts, heartbeats, failures,
+  recoveries, runner/model attribution, lease state, evidence count, and
+  evidence-backed effectiveness classification.
+- CLI, MCP, HTTP, web-control, migration, contention, idempotency, and recovery
+  coverage for the leased orchestration protocol.
+
+### Changed
+
+- A session remains compatible with unleased 0.39 clients until it is claimed;
+  after claim, context, event, and finish mutations require the current owner
+  and lease token and fail closed after expiry or takeover.
+- External orchestrators can claim every new or resumed session, renew the
+  lease before heartbeat events, attach stable attempt-scoped event ids, and
+  pass lease credentials through runner completion and evidence-backed finish.
+- The built-in memory UI reports active leases, recoverable workers, attempts,
+  event sequence, and the last heartbeat for recent agent sessions.
+
+### Fixed
+
+- Prevent two workers from concurrently mutating or finishing the same durable
+  agent session while still allowing a new attempt after release or expiry.
+- Prevent retried runner events from duplicating causal history or silently
+  changing a previously accepted event payload.
+- Exclude sessions with a live lease from stale recovery and atomically fence a
+  recovered attempt before it can load context or emit events.
+
+## 0.39.0 — 2026-07-14 (local development)
+
+### Added
+
+- Bounded agent-session lifecycle events for runner selection, start,
+  completion, failure, validation, recovery, and heartbeat updates.
+- Recoverable-session queries across CLI, MCP, and HTTP so an orchestrator can
+  find active work whose heartbeat stopped and resume the same durable session.
+- End-to-end external-runner integration coverage using a real temporary
+  project, runner profile discovery, memory context, evidence capture, finish
+  feedback, causal trace, interruption, and recovery.
+
+### Changed
+
+- Agent-session event writes update the heartbeat and append the event in one
+  SQLite transaction, failing closed if the session has already finished.
+- External orchestrators can treat DukeMemory session context as the primary
+  context layer, route CLI execution through named profiles, and record exact
+  changed-file, validation-command, and commit evidence at finish.
+- Antigravity review routing uses `Gemini 3.1 Pro (High)` while Gemini Flash
+  research routing remains `gemini-3.5-flash`.
+
+### Fixed
+
+- Interrupted runner tasks retain their DukeMemory session id and become
+  recoverable instead of silently losing causal context.
+- External CLI runners have a bounded timeout with graceful termination and a
+  forced-kill fallback.
+
+## 0.38.0 — 2026-07-14 (local development)
+
+### Added
+
+- Schema v20 agent sessions with durable start/context/finish/status/trace
+  lifecycle, explicit outcomes, validation evidence, runner attribution, and
+  process-crash recovery through SQLite state.
+- Evidence-backed feedback that writes a useful signal only after an explicit
+  successful finish with recalled memory and recorded files, validation
+  commands, or a commit; repeated finishes are idempotent and conflicting
+  finishes fail closed.
+- Named Codex, Gemini Flash High, Antigravity Pro High, and Ollama runner
+  profiles with local TOML overrides, previewable initialization, PATH-based
+  doctor checks, and CLI/MCP/HTTP visibility.
+- Vector benchmark baselines with p95/QPS regression comparison, configurable
+  thresholds, JSON evidence, and a failing local gate.
+- MCP and HTTP agent-session control surfaces plus causal traces from recalled
+  memory through actions and validation to the final outcome.
+
+### Changed
+
+- The built-in memory UI now loads one stable control snapshot initially;
+  versioned diagnostic detail is fetched only on demand.
+- Stable `web-control-center` responses include recent agent sessions, runner
+  readiness, and an explicit one-request initial-load budget while the full V12
+  response remains available at `web-control-center-v12`.
+- Existing schema 19 databases add the read-event session link before its index
+  is created, keeping upgrades safe and compatible.
+
+### Fixed
+
+- Prevent automatic positive memory feedback for successful-looking work that
+  has no explicit validation evidence.
+- Reject a second finish that attempts to rewrite a session's outcome or
+  evidence while allowing exact retries after interrupted clients.
+- Install binary upgrades through same-directory atomic rename so running MCP
+  processes keep their old executable mapping while new processes start the
+  replacement safely.
+
+## 0.37.0 — 2026-07-13 (local development)
+
+### Added
+
+- Fault-injection coverage for vec0 registry, trigger, row-membership, and table
+  corruption, with automatic reconstruction of invalid indexes.
+- Sync transport tests for concurrent writers, lock ownership, malformed and
+  expired leases, interrupted temporary files, corrupt recovery generations,
+  and private atomic replacement.
+- Vector benchmark JSON v2 with configurable warmup, iterations, vector limit,
+  p50/p95/p99 latency, throughput, backend equivalence, and exact-scale vec0
+  comparison.
+- Stable `memory-control-center` and `web-control-center` CLI/HTTP aliases while
+  retaining all versioned commands and routes for compatibility.
+
+### Changed
+
+- The autonomous supervisor now runs at the conservative level, reports
+  before/after quality and guardrails, and previews inferred feedback without
+  writing synthetic feedback events; explicit `auto-feedback` remains the
+  opt-in materialization path.
+- Atomic sync writes now fsync the containing directory after rename, and a
+  failed lock initialization removes the incomplete lock file.
+- The built-in memory UI consumes stable control-center endpoints.
+
+### Fixed
+
+- Detect vec0 indexes whose row counts happen to match while their row ids do
+  not, and repair missing/orphaned memberships on the next database open.
+- Recover missing triggers, stale trigger versions, stale registry table names,
+  and ordinary SQLite tables shadowing expected vec0 virtual tables.
+- Prevent an old sync lock guard from deleting a replacement owner's lock.
+

+# Code of conduct
+
+## Our standard
+
+Project participation must remain respectful, constructive, and safe. Examples
+of positive behavior include giving actionable technical feedback, respecting
+different experience levels and viewpoints, accepting correction, and keeping
+discussion focused on the project.
+
+Harassment, threats, discriminatory language, sexualized attention, deliberate
+disruption, publication of private information, and attacks on individuals are
+not acceptable.
+
+## Enforcement
+
+Maintainers may edit or remove contributions and may temporarily or permanently
+restrict participation when behavior harms the community or project. Decisions
+will consider context, impact, repetition, and willingness to repair harm.
+
+Report conduct concerns privately to the repository owner through GitHub. For
+security-sensitive material, use the private reporting channel in
+`SECURITY.md`. Reports will be handled as confidentially as practical; a
+maintainer involved in a report must not be its sole reviewer.
+
+This policy applies in repository discussions, issues, pull requests, review
+comments, and project-related public spaces.

+# Contributing to DukeMemory
+
+Thank you for improving DukeMemory. Keep changes focused, local-first, and
+compatible with the stable operation catalog.
+
+## Development setup
+
+The declared minimum toolchain is Rust 1.91. From the repository root:
+
+```bash
+cargo fmt --all -- --check
+cargo check --locked --all-targets
+cargo clippy --locked --all-targets --all-features -- -D warnings
+cargo test --locked
+```
+
+See `docs/testing.md` for coverage, fuzzing, MCP conformance, mutation, and
+release-gate commands.
+
+## Pull requests
+
+- Open a focused branch and pull request; direct updates to `main` are blocked.
+- Add regression coverage for behavior changes and security boundaries.
+- Keep mutations dry-run-first and reversible unless the interface explicitly
+  requires an apply operation.
+- Update the operation catalog and generated documentation when a stable CLI,
+  MCP, or HTTP contract changes.
+- Do not commit credentials, local `.agent` data, model artifacts, build output,
+  or generated release archives.
+- Do not create tags, releases, or registry publications from a contribution.
+
+The required GitHub checks must pass before merge. Security-sensitive changes
+to authentication, egress, RAG ingestion, audit integrity, workflows, or the
+release pipeline require explicit maintainer review.
+
+## Compatibility and deprecation
+
+Prefer the unversioned stable surfaces. Compatibility aliases may remain hidden
+for existing clients, but new version-suffixed commands should not be added.
+Breaking changes require a documented migration path and release note.
+
+## Security reports
+
+Follow `SECURITY.md`; never disclose an unpatched vulnerability in a public
+issue or pull request.

 ## Local First
 
 `dukememory` stores data in the project by default:
@@ -149,11 +213,183 @@ No cloud service is required. The default local profile uses MiniLM embeddings
 stored in SQLite; semantic recall remains optional for projects that only need
 FTS.
 
+On Unix, new database directories are created with mode `700` and the SQLite
+database plus WAL/SHM sidecars are forced to mode `600`. SQLite
+`secure_delete=FAST` reduces residual deleted content. This is access hardening,
+not application-level database encryption; use encrypted host storage for
+sensitive projects and age-encrypted bundles for remote sync.
+The bundled SQLite runtime is release-gated at `>=3.51.3` (currently 3.51.3).
+Set `DUKEMEMORY_SQLITE_DURABILITY=strict` for `synchronous=FULL`, full-fsync,
+and checkpoint-fsync semantics; the default `balanced` profile retains WAL plus
+`synchronous=NORMAL`. `dukememory audit --verify` validates the event and

+
+`context` combines brief, optional target impact, and doctrine in one audited
+read. A successful finish creates automatic `useful` feedback only when the
+session recalled memory and includes explicit evidence: a changed file,
+validation command, or commit. Exact finish retries are safe; a conflicting
+second finish is rejected. `failed`, `partial`, and `abandoned` outcomes never
+produce automatic positive feedback.
+
+External orchestrators should claim a session before loading context. A live
+lease fences context, event, renew, release, and finish mutations to one owner
+and opaque token; after release or expiry, a new claim creates a new attempt.
+Unclaimed sessions remain compatible with the 0.39 lifecycle. Recovery never
+returns a session with an unexpired lease.
+
+Orchestrators can record bounded JSON-object events with `agent-session event`;
+every accepted event refreshes session activity in the same transaction.
+`--event-id` makes delivery retry-safe: an exact retry returns the existing
+result, while reusing the id with another type or payload fails closed.
+Supported events are `heartbeat`, `runner_selected`,
+`runner_started`, `runner_completed`, `runner_failed`, `validation`, and
+`recovery`. Trace metrics include ordered event sequences, attempt attribution,
+lease contention, orphaned attempts, recovery latency, heartbeat freshness,
+runner failures, evidence counts, and effectiveness. Cleanup targets explicitly
+selected terminal states older than their configured retention window,
+previews by default, and deletes their lifecycle events transactionally when
+`--apply` is explicitly supplied. Session JSON exposes an explicit
+`attempt_state` (`idle`, `leased`, `stale`, `released`, or the terminal status),
+and list operations support status/outcome filters plus bounded pagination.
+The same operations are exposed as `memory_session_claim`,
+`memory_session_renew`, `memory_session_release`, `memory_session_event`, and
+`memory_session_recover` over MCP; retention is exposed as
+`memory_session_cleanup`. The HTTP equivalents live under `/agent-sessions/*`.
+
+Default retention and pagination can be overridden in `.agent/config.toml`:
+
+```toml
+[agent_sessions]
+default_page_size = 20
+completed_retention_days = 30
+failed_retention_days = 90
+partial_retention_days = 90
+abandoned_retention_days = 14
+```
+
+## Stable Control Snapshot
+
+Use the unversioned control surface for integrations:
+
+```bash
+dukememory web-control-center --json
+curl http://127.0.0.1:8765/web-control-center
+```
+
+The response schema is `stable-v1` across CLI, MCP `memory_status`, HTTP, and
+the initial web UI. It contains one normalized health/quality/recall/autonomy
+summary, recent session state, optional runner readiness, a database revision,
+and cache telemetry. Repeated requests reuse the snapshot for a short bounded
+TTL while any relevant SQLite or control-file revision invalidates it.
+
+Historical `/web-control-center-v3` through `-v12` routes and their CLI
+commands remain available for pinned clients but are deprecated and hidden from
+normal CLI help. Full legacy detail is opt-in through
+`/web-control-center?view=details` or `web-control-center --details`; the web UI
+loads it with one request instead of the former diagnostic fan-out.
+
+### Named Runner Profiles
+
+Any external orchestrator can use the session lifecycle as its durable
+coordination layer: start or resume a session, claim a fenced attempt, load
+audited context, select a named runner profile, renew the lease, capture
+workspace/validation/commit evidence, and finish once with a causal trace. A
+second worker cannot resume the task while its lease is live. Runner failure
+and cancellation never create automatic positive feedback.
+
+Named runner profiles are built in and may be overridden in
+`.agent/runner-profiles.toml`:
+
+```bash
+dukememory runner-profile list --json
+dukememory runner-profile doctor --json
+dukememory runner-profile init --json
+dukememory runner-profile init --apply --json
+```

 local SQLite database, while push/pull moves reviewable sync bundles.

+## Supported versions
+
+Security fixes are provided for the latest published DukeMemory release and
+the current `main` branch. Older releases may be used to reproduce an issue,
+but are not maintained independently.
+
+## Reporting a vulnerability
+
+Do not open a public issue for a suspected vulnerability. Use GitHub's
+[private vulnerability reporting](https://github.com/danilkryachko/dukememory/security/advisories/new)
+so reports, proof-of-concept material, and remediation work stay private until
+a coordinated disclosure is ready.
+
+Please include:
+
+- the affected version or commit;
+- the deployment mode (local CLI, HTTP, MCP, sync, or model provider);
+- reproduction steps and the expected security boundary;
+- impact, prerequisites, and any suggested mitigation;
+- whether the report or proof of concept may be credited publicly.

+The maintainer will acknowledge a complete report within three business days,
+triage severity and scope, and coordinate a fix and disclosure timeline. Avoid
+accessing data that is not yours, disrupting services, or publishing details
+before the fix is available.
+
+## Security boundaries
+
+DukeMemory is local-first. Filesystem permissions and encrypted host storage
+remain part of the trust boundary. The SQLite audit chain detects accidental
+or unauthorized modification after a trusted checkpoint, but it is not a
+substitute for an externally witnessed signature. Remote HTTP/MCP deployments
+must terminate TLS at a trusted proxy and configure authentication, origin,
+host, egress, and resource-limit policies as documented in

+## Boundaries
+
+- `src/domain.rs` owns memory type, scope, and status values. Invalid values cannot enter a mutation use case.
+- `src/application.rs` is the adapter-facing use-case layer. Core create, update, status, delete, retrieval, and maintenance calls pass through it.
+- `src/storage.rs` exposes the crate-private `MemoryStore`; SQLite details stay under `src/app/`.
+- `src/operation_catalog.rs` maps stable memory, retrieval, RAG, release, and agent-session operations across CLI, MCP, and HTTP. The checked-in table is in [operations.md](operations.md).
+- `src/http_api.rs` owns transport-neutral HTTP responses, status mapping, and response security headers.
+- `src/app/mcp_transport.rs` owns bounded newline and Content-Length framing; `mcp_server.rs` owns JSON-RPC lifecycle, tool schemas, and dispatch, while `mcp_server/tasks.rs` owns durable task state and protocol-specific task results.
+- `src/app/observability/release_gate.rs` owns release-gate v3 composition and effective RAG profiles; `rag_eval_summary.rs` isolates the lightweight web RAG snapshot from the broader observability module.
+- `src/app/http_ingest_routes.rs` isolates project-contained file ingest routes from the broader HTTP diagnostic surface.
+
+Legacy maintenance and observability commands remain grouped under `src/app/`. New cross-surface behavior should enter through the application layer instead of adding independent mutation logic to each adapter.
+
+## Write path and invariants
+
+Every core mutation follows the same sequence:
+
+1. The adapter parses transport data into typed domain values.
+2. `MemoryApplication` invokes the core use case.
+3. Central validation rejects empty content, invalid confidence, invalid enum values, and accidental secrets unless explicitly allowed.
+4. `MemoryStore` writes the memory, links, and audit event in one SQLite transaction.
+5. The adapter maps the result to its own response format.
+
+HTTP maps bad input to `400`, missing resources to `404`, conflicts to `409`, and unexpected failures to opaque `500` responses with incident ids. File ingest resolves canonical paths under the selected project root, and mutation-capable maintenance routes are preview-first.
+
+## SQLite lifecycle
+
+The current schema version is stored in `schema_versions`. Migrations are version-gated and transactional; startup verifies critical tables, columns, indexes, triggers, and the final schema version. HTTP resolves the selected project once per request and opens one connection for that request. Process-local initialization caching avoids rerunning schema setup for an already verified database. Unix database files and sidecars are mode `600`, newly created database directories are mode `700`, and SQLite uses `secure_delete=FAST`. The bundled runtime is gated at SQLite 3.51.3 or newer, and `DUKEMEMORY_SQLITE_DURABILITY` selects the explicit `balanced` or `strict` fsync profile.
+
+Graph edges live in `memory_edges` with foreign keys, uniqueness, confidence bounds, provenance, and atomic audit writes. Symmetric `relates_to` edges are canonicalized for storage and traversed in both directions. Schema v24 adds valid time (`valid_from`/`valid_to`), knowledge time (`observed_at`), and an optional source observation. `memory_observations` keeps evidence kind/reference plus Git branch, commit, and worktree context, allowing an as-of graph to answer both “what was valid then?” and “what did the agent know then?”. File-backed observations encode a project-contained path, SHA-256, and size in the evidence reference; drift/review revalidate the latest observation and RAG generation excludes cards whose file evidence changed or disappeared without mutating their durable status. Schema v25 adds durable, lifecycle-scoped MCP task records; v26 adds exact-hash RAG trust promotion; v27 hash-chains audit events and retention checkpoints; v28 adds evidence-backed causal observation kinds. `temporal-graph --commit` resolves the knowledge cutoff from recorded evidence for an exact Git commit.
+
+## Retrieval policy
+
+Retrieval loads a `RetrievalPolicy` once into `RetrievalQualitySignals`. The environment override `DUKEMEMORY_RANKING_PROFILE` wins; otherwise the policy comes from the selected database project's `.agent/ranking-profile.json`. Ranking never reads policy from the process working directory per result.
+
+RAG ingest prefers language-aware structural boundaries for supported text/code formats while retaining bounded line chunking as a fallback. Every selected RAG source carries a stable evidence reference and content hash; eval v7 separates retrieval ranking, deterministic extractive grounding, and generated-output guard fixtures while reporting development/holdout metrics and separate partition signatures. Baseline v3 binds results to both the canonical case corpus and retrieval configuration.
+
+Prompt-injection triage is a pure library boundary in `src/rag_security.rs`.
+Ingest keeps suspicious chunks for inspection, source health counts them as
+quarantined, and both lexical and semantic retrieval exclude them before
+ranking. The advanced eval reports memory-card provenance separately from
+file-chunk provenance and runs a deterministic pre-retrieval attack-filter
+fixture set; it does not claim protection from novel attacks or prove generated
+answer safety.
+The fixture is checked in and versioned independently from detector code. Text
+is normalized for Unicode compatibility/format characters and common
+homoglyphs, while bounded Base64 candidates are inspected before retrieval.
+Clean source hashes remain explicitly unreviewed until operator promotion.
+
+Advanced eval is deterministic and evidence-first. It audits only explicitly typed causal edges, treats poisoning matches as review candidates, measures global graph representation through connected components, and checks both valid-time and knowledge-time consistency. It does not infer causality, claim that heuristic matches prove compromise, or advertise hierarchical GraphRAG community summarization that the implementation does not provide.
+
+## Transport and egress boundaries
+
+MCP profiles bound the advertised tool surface; list cursors, Resources, and Tasks avoid forcing one large synchronous context exchange. The stable 2025 family keeps its initialize lifecycle. The locked `2026-07-28` release candidate uses per-request metadata and `server/discover`; its Tasks Extension is negotiated per request and is not wire-compatible with 2025 Tasks. Schema v25 stores tasks durably in SQLite, isolates them by client identity and lifecycle, and retains terminal results across MCP process restarts. Tool input is validated against closed, bounded Draft 2020-12 schemas before dispatch.
+
+HTTP rejects ambiguous framing before reading the body and attaches a correlation id to every response/access event. Static tokens retain full/read compatibility, while a trusted OAuth/OIDC gateway supplies independently enforced read, write, maintenance, and filesystem scopes from explicit proxy CIDRs and publishes RFC 9728 protected-resource metadata. HTTP and MCP tool calls derive their required OAuth scope from the operation catalog. Bounded rate-limit identity storage plus global/per-client HTTP concurrency return `429` or `503` under pressure. MCP task workers have global and per-principal admission limits, and both sessions and durable tasks are principal-bound. The local UI loads same-origin CSS and JavaScript assets under a strict CSP with inline script/style execution disabled. Admission, stored-card scanning, and export redaction share structured secret signatures so one transport cannot bypass another's policy. HTTP and MCP framing parsers have property-based arbitrary-input and ambiguity coverage. Provider egress centrally validates HTTP(S) URLs, disables redirects, checks and pins DNS results, and blocks private, link-local, metadata, and special-use destinations unless explicitly allowed.
+
+`scripts/architecture-budget.sh` caps growth in the remaining legacy
+aggregation files (`app`, CLI parsing/dispatch, observability, MCP, HTTP routes,
+diagnostics, and the large CLI integration suite). `tests/architecture_budget.rs`
+also freezes the reviewed direct and optional runtime dependency counts. New work should continue extracting
+cohesive modules (as the HTTP authorization, release-gate, and RAG-security
+boundaries do) instead of raising those budgets.
+
+## Local model safety
+
+The default local embedding model and built-in SmolLM2 generation presets use immutable Hugging Face revisions and verified SHA-256 digests. Tensor access is bounds- and type-checked, output dimensions are derived from the model output, and embedding engine initialization is separated from concurrent inference.
+
+Custom `hf://` generation models support `hf://owner/repo@revision:file.gguf`. User-selected custom artifacts are not assigned a project-owned checksum; deployments should pin a revision and verify the artifact independently.
+
+## Cargo feature matrix
+
+| Build | Capabilities |
+| --- | --- |
+| default | FTS plus local MiniLM embeddings |
+| `--no-default-features` | minimal FTS build without ONNX, tokenizer, or Hugging Face dependencies |
+| `--features vec` | default capabilities plus sqlite-vec |
+| `--all-features` | embeddings, sqlite-vec, and local llama.cpp generation |
+
+Release builds use stripped symbols, thin LTO, a single codegen unit, and no
+incremental state. `release-minimal` switches to size optimization and fat LTO
+for FTS/external-embedding servers; `scripts/reproducible-build-check.sh`
+compares two isolated builds byte-for-byte with fixed timestamps and remapped
+source paths.
+
+## Extension rules
+
+- Add domain values and invariants in `src/domain.rs` or the relevant application use case.
+- Add a stable cross-surface operation to `OPERATION_CATALOG`, then update CLI/MCP/HTTP adapters from that definition and refresh `docs/operations.md`.
+- Add schema changes as a new numbered migration and extend structural verification and migration tests.
+- Keep external model downloads pinned and checksummed; keep their dependencies behind a Cargo feature.
+- Put focused integration tests in a dedicated file under `tests/`; compatibility-only CLI tails may be included from `tests/cli/`, but new feature suites must not expand the legacy monolith.

+sync is automated. Keep that and the telemetry hash key outside the repository
+with mode `600`; the telemetry key must contain at least 16 characters of
+cryptographically random, text-encoded material.
+The read-only bearer is optional and must differ from the full token. It can
+read dashboards and MCP read tools but cannot invoke cataloged writes. The
+listener rejects invalid/zero limits at startup. The rate-limit identity table,
+simultaneous HTTP work, and asynchronous MCP task workers all have independent
+hard bounds; task admission is also bounded per authenticated owner.
+
+### OAuth/OIDC authentication gateway
+
+Native static bearer tokens remain the simplest deployment. For OAuth 2.1 or
+OIDC, put DukeMemory behind an authentication gateway that validates token
+signature, issuer, expiration, audience/resource, and scopes before forwarding.
+DukeMemory deliberately does not parse or pass through the external access
+token. The gateway must remove every client-supplied `Authorization`,
+`X-DukeMemory-Principal`, `X-DukeMemory-Scopes`, and `X-Forwarded-For` header,
+then inject a stable principal and the validated `memory:read` and/or
+`memory:write`, `memory:maintenance`, and `memory:filesystem` scopes. Request
+only the scopes each client needs: maintenance covers destructive/repair
+operations, while filesystem covers local source ingestion and drift checks.
+No write scope implies either stronger scope. Enable this mode only with an
+explicit gateway CIDR:
+
+```ini
+DUKEMEMORY_HTTP_TRUSTED_PROXY_AUTH=true
+DUKEMEMORY_HTTP_TRUSTED_PROXY_CIDRS=127.0.0.1/32,::1/128
+DUKEMEMORY_PUBLIC_ORIGIN=https://memory.example.com
+DUKEMEMORY_OAUTH_AUTHORIZATION_SERVERS=https://id.example.com/tenant
+```
+
+Requests carrying identity headers from any address outside those CIDRs are
+unauthorized. The same trusted chain determines the rate-limit client from
+`X-Forwarded-For`; malformed chains fail closed. DukeMemory publishes protected
+resource metadata at `/.well-known/oauth-protected-resource` and includes its
+URL in `WWW-Authenticate` challenges. This follows RFC 9728 discovery expected
+by MCP HTTP clients; the gateway remains responsible for full token validation
+and RFC 8707 audience/resource binding.
+
+Local SQLite files are not application-level encrypted. DukeMemory enforces
+mode `600` on the database and WAL/SHM sidecars, creates new database directories
+with mode `700`, and enables SQLite `secure_delete=FAST`; production hosts should
+still use encrypted storage (for example LUKS or FileVault) when memory content
+is sensitive. Remote/VDS bundles should use the built-in authenticated age
+encryption.
+The bundled SQLite version is release-gated at 3.51.3 or newer. Strict
+durability enables `synchronous=FULL`, full-fsync, and checkpoint-fsync; run
+`dukememory audit --verify --json` as an operational integrity check.
+
+Validate the effective profile before starting or releasing the service:
+
+```bash
+dukememory deployment-profile \
+  --mode reverse-proxy \
+  --host 127.0.0.1 \
+  --auth-token-file /etc/dukememory/http-token \
+  --public-origin https://memory.example.com \
+  --json
+```
+
+The report fails closed on public binds, missing bearer or trusted-proxy
+authentication, incomplete OAuth discovery/trust configuration, a
+non-HTTPS origin, origin-policy mismatches, unsafe token files, and an encrypted
+sync target without a valid passphrase. Invalid HTTP/MCP admission limits and
+per-owner limits above their global bounds are also blockers. It states the current limits
+explicitly: SQLite at-rest encryption is host-managed. Production
+observability includes JSON access logs, request IDs, `/metrics`, and bounded
+batched OTLP/HTTP JSON logs, traces, and request-count/duration metrics.
+Signal-specific `OTEL_EXPORTER_OTLP_{LOGS,TRACES,METRICS}_ENDPOINT` values are
+used as-is; the generic endpoint receives the standard `/v1/logs`, `/v1/traces`,
+and `/v1/metrics` suffixes. Global and signal-specific OTLP protocols,
+headers, and timeouts are supported. `DUKEMEMORY_TELEMETRY_IDENTIFIERS` can be
+`plain`, `hash`, or `omit`; use `hash` or `omit` for public traffic so peer and
+derived client addresses are protected in both stderr logs and exported data.
+Outbound collector connections use the same pinned-DNS egress
+policy as model providers. Prefer exact scheme/host/port entries in
+`DUKEMEMORY_EGRESS_ALLOW_ORIGINS`; when that variable is configured, the older
+host-only `DUKEMEMORY_EGRESS_ALLOW_HOSTS` fallback is ignored. Plaintext
+non-loopback HTTP also requires an explicitly allowed origin. External model
+generation is bounded by `DUKEMEMORY_MODEL_MAX_CONCURRENT`,
+`DUKEMEMORY_MODEL_MAX_PROMPT_BYTES`, `DUKEMEMORY_MODEL_MAX_RESPONSE_BYTES`,

+# Supply-chain policy
+
+All third-party GitHub Actions are pinned to immutable 40-character commit SHAs. `tests/supply_chain.rs` rejects mutable workflow references.
+
+CI runs `cargo-deny` for advisories, licenses, bans, and sources. The dependency graph currently has two reviewed unmaintained build-time transitive exceptions:
+
+- `RUSTSEC-2024-0436`: `tokenizers 0.23.1 → paste`. `tokenizers` is required only by the optional `local-embeddings` feature. Remove the exception when upstream replaces `paste`.
+- `RUSTSEC-2026-0173`: `age 0.12.1 → i18n-embed-fl → proc-macro-error2`. `age` provides encrypted sync bundles. Remove the exception when upstream replaces `proc-macro-error2`.
+
+Both are pinned by `Cargo.lock`, are not runtime parsing or network entry points, and must remain visible in `deny.toml`; new advisory exceptions require their own rationale.
+
+The supply-chain workflow installs the pinned `cargo-cyclonedx 0.5.9` release and generates a CycloneDX 1.5 JSON SBOM:
+
+```bash
+cargo install cargo-cyclonedx --version 0.5.9 --locked
+cargo cyclonedx --format json --all-features --target all \
+  --spec-version 1.5 --override-filename dukememory.cdx
+jq -e '.bomFormat == "CycloneDX" and (.components | length > 0)' dukememory.cdx.json
+```
+
+Tagged releases also generate GitHub/Sigstore build-provenance attestations for
+every archive, checksum, the combined `SHA256SUMS`, and the CycloneDX SBOM. The
+attestation action is pinned to the reviewed immutable SHA for `actions/attest
+v4.1.1`. After downloading an asset, verify both its checksum and provenance:
+
+```bash
+sha256sum --check SHA256SUMS --ignore-missing
+gh attestation verify dukememory-x86_64-unknown-linux-gnu.tar.gz \
+  --repo danilkryachko/dukememory

+# Testing and fuzzing
+
+The normal quality gate uses the pinned lockfile:
+
+```bash
+cargo fmt --all -- --check
+cargo check --locked --all-targets --all-features
+cargo clippy --locked --all-targets --all-features -- -D warnings
+cargo test --locked --features vec
+```
+
+CI also generates source-based coverage with `cargo-llvm-cov` 0.8.6 and
+enforces a 55% repository-wide line floor. The current suite has measured above
+60%; the lower enforced floor leaves bounded platform variance while preventing
+the former 30% threshold from masking a large regression.
+`scripts/coverage-budget.sh` additionally enforces higher per-file floors for
+protocol, SQLite, audit, auth, MCP transport/server, RAG security, and ingest.
+The quality job rejects growth past the checked-in dependency and duplicate
+version budgets. CodeQL analyzes compiled Rust on pushes, pull requests, and a
+weekly schedule; a separate weekly/manual cargo-mutants job gates bounded
+critical security modules.
+
+The protocol framing parsers are exposed from the small `dukememory::protocol`
+library boundary so unit/property tests and fuzz targets exercise the same code
+used by the HTTP and MCP adapters. The pure pre-retrieval quarantine detector is
+similarly exposed as `dukememory::rag_security`, keeping its fuzz target free of
+database and model-provider state.
+
+Fuzzing requires nightly Rust and `cargo-fuzz` 0.12.0:
+
+```bash
+cargo install cargo-fuzz --version 0.12.0 --locked
+cargo fuzz run mcp_content_length -- -max_total_time=60
+cargo fuzz run http_framing -- -max_total_time=60
+cargo fuzz run rag_prompt_injection -- -max_total_time=60
+cargo fuzz run sync_payload -- -max_total_time=60
+cargo fuzz run egress_url -- -max_total_time=60
+```
+
+Pull requests touching protocol framing get a bounded 30-second smoke run per
+target. The scheduled workflow runs each target for five minutes and uploads
+crash artifacts on failure.
