docs(roadmap): turn Phase 02b from a diagnosis into a gated plan by cemililik · Pull Request #20 · HodeTech/LearnStack

cemililik · 2026-09-12T14:12:17Z

Summary

Rewrites docs/roadmap/phase-02b-events-auth.md (469 → 1282 lines) from four pre-development reviews. Three of its four "Correction" sections described defects the corpus had already repaired — architecture/15 withdrew the "no double dispatch" invariant and specified the lease, and Packet 5 shipped the abstract PartitionKey — so those sections now state what the phase inherits and link the owner instead of restating it. The one defect still open, the realm's missing tenant_id claim, keeps its #### Correction.
Adds a nine-packet sequence and a twenty-row decision register. Each row states the open question, the reviewers' proposal (marked explicitly as not a decision), the vehicle this repository's rules require for the answer to count, and the packet it blocks. P02b-0 writes no code.
Rewrites Deliverables / Completion Criteria / Risks / Phase Exit so each criterion is something a named test can fail — the reviews found a third of Scope had no observable criterion, and that the previous exit omitted the host/JWT cross-check, both Packet 9 hand-offs and LS0002.
Three carrier reconciliations ride along, each against a decision that is already Accepted: Phase 11 now verifies the claim protocol and the dead-letter contract rather than rebuilding what architecture/15 assigns to 02b, and gains the /readyz deliverable and the outbox/inbox purge its own prose already implied; decisions/README reserves ADR-0046 and ADR-0047 against Phase 02b; the roadmap index takes the phase's new title, which had omitted background jobs.

The register decides nothing. Where the corpus already answered — the lease is the specified design; only the owning frame writes, signals and reconciles — the phase now carries that answer instead of re-opening it as a choice. Where it has not, the question is a gate whose amendment is named and Accepted before the code it governs.

Method

Every citation in the three review documents was re-opened at HEAD before acting, because all three were written at a448ff7 and the corpus had since moved through Packet 10 (Standards 21 grew ~1071 lines; the *Probes.cs planted-offender convention landed; phase-02a re-homed the Hangfire JobActivator). That pass found findings already closed and reviews that were themselves wrong — one claimed both ADR-0036 carriers "omit row 10" when the erratum names it three times; another claimed a shipped test "asserts a constant and cannot fail" when it had demonstrably caught a real defect. The rewrite was then put through an independent adversarial review whose findings were each attacked before being applied; 41 corrections landed from it, including one blocker in my own draft (below).

Notable finding, found in this rewrite

The draft asserted both sides of a live corpus contradiction as adjacent completion criteria: the catalogued Backend_RequiresJwt_OnAllAuthenticatedRoutes (booked to Phase 02b) says every endpoint outside the public allow-list answers 401 without a bearer token, while ADR-0036 matrix row 2 requires a 404 byte-identical to an unknown host's. Both cannot hold for the same request, and the default UseAuthorization wiring answers the one the matrix forbids. That is now G20, with the tenant_mismatch / not_found code split the shipped assertion middleware assigns to this phase by name, and one criterion instead of two.

Test plan

No code changed; these are the gates CI runs on this diff, all verified locally against origin/main:

meta — markdown link audit: 77 relative targets in the phase document resolve, and every #fragment matches a real heading (checked beyond CI, which strips fragments).
meta — Accepted-ADR disclosure: no Accepted ADR body changed. docs/decisions/README.md is the index and is excluded by the check.
meta — docs/analysis/ residual scan: clean; no gitignored path is cited from a committed file.
meta — commit hygiene: the commit-msg hook passes on this commit (run locally with the same hook CI uses).
Prose hard-wraps at 88 columns, the one exception being a single bare URL, which the standard exempts.
Structural read-through: the six required phase sections present and in order; all G1–G20 and P02b-0–P02b-8 referenced are defined; every gate's Blocks cell and its packet's Cannot start until cell agree.

Risk

Documentation only. No schema, no contract, no code, no tenant-isolation boundary touched.
This PR settles no one-way door. Twenty gates are registered and open; the two reserved ADR numbers are reserved, not drafted. That is deliberate — several answers change what an Accepted ADR decided, which needs a dated Amendment, not a roadmap edit.
Amendment numbers will need re-sequencing if several land together. The register names the next free number for each ADR as of this commit (verified: ADR-0006 → 3, ADR-0003 → 6, ADR-0032 → 4, ADR-0033 / 0036 / 0040 / 0044 → 8, ADR-0038 → 2). Three ADRs are named by more than one gate — ADR-0036 Amendment 8 by G11, G20 and conditionally G9, which can be one amendment; ADR-0033 by both G6 and G7; ADR-0006 by G4 plus three conditional branches — so whichever lands second takes the next number.
Phase 11's scope narrows. Two of its bullets moved from building the dead-letter and claim mechanisms to verifying them under multi-pod load. architecture/15 already says the choice "is made once, in Phase 02b", so this reconciles Phase 11 with that sentence rather than changing an owner.
The behavioural CI job is not a required check today. Every behavioural criterion in this phase sits in it; CONTRIBUTING names the branch-protection edit as the one remaining step, and the phase now takes it in P02b-8 rather than leaving the exit gate resting on a check that cannot block a merge.

Summary by Sourcery

Convert Phase 02b from a defect diagnosis into a dependency-gated implementation plan for events, background jobs, identity integration, and sessions.

New Features:

Define Phase 02b as a nine-packet implementation plan covering event delivery, background jobs, authentication, and sessions.
Add a gated decision register that requires accepted ADRs and amendments before dependent implementation work begins.

Bug Fixes:

Correct roadmap and carrier inconsistencies around outbox leasing, subscriber dead-letter handling, tenant claims, authentication responses, audit ownership, and background-job ownership.

Enhancements:

Replace diagnosis-oriented phase content with observable deliverables, completion criteria, risks, and an explicit phase-exit checklist.
Reconcile Phase 11 responsibilities so it verifies Phase 02b's event and job mechanisms while owning their production hardening and operations.
Reserve ADR-0046 and ADR-0047 for event-delivery and background-job runtime decisions.

CI:

Add the behavioural CI job and branch-protection update to the phase exit plan, alongside structural and documentation validation requirements.

Deployment:

Clarify Phase 11 ownership of readiness, multi-pod dispatcher validation, dead-letter operations, and outbox/inbox purging.

Documentation:

Rewrite the Phase 02b roadmap with inherited contracts, explicit scope boundaries, nine implementation packets, twenty decision gates, named tests, and revised exit criteria.
Update roadmap and decision indexes to reflect the expanded phase title and reserved ADRs.

Tests:

Expand planned integration, behavioural, architecture, identity, session, audit, job, and concurrency coverage so each phase criterion can fail observably.

Summary by CodeRabbit

Documentation
- Added reserved entries for upcoming decisions covering event delivery, subscriber failures, and background job runtime.
- Updated the Phase 02b roadmap to include events, background jobs, identity, and sessions.
- Expanded production-hardening criteria for dead-letter alerts, replay and recovery paths, purge authorization, retention limits, lease tuning, readiness checks, and liveness behavior.

Four pre-development reviews read the phase and agreed on the shape of the problem: the document diagnosed the events subsystem accurately and was not yet a plan. Three of its four "Correction" sections described defects the corpus had already repaired — architecture/15 withdrew the double-dispatch invariant and specified the lease, and Packet 5 shipped the abstract PartitionKey — so a reviewer checking those deliverables found nothing to do. Meanwhile the choices that fix a schema, a transaction shape and a token contract were left to "the packet", and a third of Scope had no observable completion criterion. What replaces it: an inherited-baseline section that says what is already decided and links its owner rather than restating it; an explicit not-in-this-phase list where every deferral names its owning phase, and every building block its port, default implementation and trigger; a nine-packet sequence; a twenty-row decision register that states each open question, the vehicle this repository's rules require for the answer to count, and the packet it blocks; and Deliverables, Criteria, Risks and Exit rewritten so each criterion is something a named test can fail. The register decides nothing. Where the corpus already answered — the lease, and the rule that only the owning frame writes and reconciles — the phase now carries that answer instead of re-opening it; where it has not, the question is a gate with its amendment named and Accepted before the code it governs. Three carriers are reconciled with decisions that are already Accepted, which is why they ride along: Phase 11 verifies the claim protocol and the dead-letter contract rather than rebuilding what architecture/15 assigns to 02b, and gains the /readyz deliverable and the outbox/inbox purge its own prose already implied; decisions/README reserves 0046 and 0047 against Phase 02b; and the roadmap index takes the phase's new title, which had omitted background jobs.

Reviewer's Guide

This documentation-only PR transforms Phase 02b from a defect-focused description into a dependency-ordered, decision-gated implementation plan. It records inherited architecture, exposes unresolved cross-document contradictions, assigns each open question to an ADR or standards vehicle, defines nine packets and 20 blocking gates, and reconciles Phase 11 and roadmap index ownership without making the pending decisions themselves.

**nitpick:** The phase says it registers no job and that the first jobs arrive in Phase 04 and Phase 08a, but Phase 11 already specifies two Hangfire audit jobs (`learnstack:audit:partition-management` and `learnstack:audit:retention-purge`). This makes the stated chronology and ownership of the first job definitions false or ambiguous.

**Suggested fix:** Qualify this as the first product-domain job definitions, or list the Phase 11 audit jobs as an earlier/later exception and reconcile the ownership wording.

Three findings from review, each verified against the files before acting. Phase 11's Completion Criteria required an integration event to be "consumed exactly once by a subscriber in another process". Nothing in the corpus promises that: the glossary and Events and Outbox both state at-least-once delivery with consumer-side idempotency through IInboxGuard, which is the contract this change's Phase 02b rewrite leans on throughout. A cross-process transport does not change it. The criterion now asserts at-least-once delivery plus the observable that matters — a forced redelivery of the same envelope producing exactly one effective business side effect — and says the retry and dead-letter contract it exercises is Phase 02b's, unchanged. The three Scope bullets this change added to Phase 11 had no matching Completion Criteria, which is the same traceability defect the Phase 02b reviews found in Phase 02b. Each now has one: two dispatcher processes in separate pods with lease-duration tuning and a paging lost-lease alert; per-counter dead-letter alert thresholds that fire on a seeded terminal row and not on ordinary retry, with replay under contention; and a purge running under a principal the platform-admin gate admits rather than the dispatcher's credential, against an inbox retention floor of at least the maximum redelivery window. Phase 02b's "registers no job" bullet said the first jobs arrive in Phase 04 and Phase 08a. That chronology is correct — both precede Phase 11 in the dependency map — but it read as though jobs exist only there, when Phase 11 implements ADR-0028's two audit jobs. The sharper point is why that matters: those two are tenantless, and they meet an enqueue guard that refuses a payload with no tenant, which is what G9's platform-job class has to settle. The bullet now says so. Two requests in the review are not taken. A criterion per fair-share control would expand a section this change does not touch, and § Resource fairness already has a criterion plus an exit line. And the Phase Exit Decision already opens "when all of the following hold" and closes "there is no third option", so a further requirement that it depend on the Completion Criteria adds a clause without adding a gate. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Brings the branch up to date with PR #19 so the gate can evaluate it. Merged rather than rebased: review has started on this pull request and a force-push would orphan the reviewer's line anchors, which [Git Workflow](docs/standards/14-git-workflow.md) lists as a validation item.

Each finding was re-verified against the files and the code before acting. G1's vehicle named ADR-0006 and stopped there. ADR-0010 § Idempotency makes two things mandatory that the shared-table leaning changes — the inbox is "the module's own inbox table", and the guard is called by the consumer — and the catalogued Integration_Event_Handlers_Use_InboxGuard is a structural rule that looks for that call inside the handler. A transport-claimed delivery that reconciled only the listed documents would leave two Accepted contracts in conflict and fail a required rule while being correct. Both are now in the gate's vehicle, with the rule's assertion re-written in the same record. Login on the two seed hosts needed a transport nobody named. The hosts are *.learnstack.local, the session cookie is mandatorily Secure, and the frontend's dev script serves plain HTTP — so the cookie this phase sets would be accepted and never sent back, and a stub route test that inspects the Set-Cookie header would not notice. G12 now asks for the transport, § Login topology states the constraint and forbids dropping Secure, and the criterion asserts the round trip on each real host rather than the header. The token-keyed rate limit was specified as a stage after authentication, over a shipped global limiter that partitions every request on the socket peer at the anonymous budget and runs before authentication. Two users behind one BFF share that quota, and a request it rejects never reaches a token stage, so the criterion as written could not pass. G14 now covers what happens to the early stage once a caller is validated, and the criterion runs the whole middleware chain from one peer address. Seven of the review's suggestions are taken in the same pass, each closing a hole this change introduced: the producer dead-letter's audit success and its audit failure are now separate criteria, matching the subscriber side; the domain-event failure criterion this rewrite had dropped is back, with the cancellation case for the per-delivery deadline; the session criterion counts one logical session version rather than one Set-Cookie header, which a chunking adapter can exceed while behaving correctly; Phase 11's dead-letter operability names the job counter beside the two event counters and drives a real terminal transition rather than a seeded row; the inbox retention floor is split so 02b states the replay contract and Phase 11 picks the interval; G7 records that a resolution splitting the transition from its MUST row across transactions needs a superseding record, not an amendment; and G19 notes that a provisioning event needs its own proof, because provisioning leaves ITenantContext unresolved. Two requests are not taken. The accessibility timeout warning belongs to the phase that ships a rendered surface, and Standards 16 already binds it. And a criterion per fair-share control would expand a section this change does not touch, which already has a criterion and an exit line.

Three inline findings, each checked against the carrier before acting. The producer dead-letter alert had a cumulative threshold, and Events and Outbox § Producer side is explicit that "the alert is on the counter's rate, not on the table's size". A criterion satisfied by a cumulative count does not observe the shape the architecture requires, so the producer alert now carries a named rate window. The real-terminal-transition condition this change already added is kept, and the subscriber and job alerts keep their own thresholds; the three are asserted separately rather than as one clause. Recovery was one clause covering all three domains, which the same section rules out: "the two sides fail independently and need separate handling", and the job side is a third. Each path now has its own case and its own expected single effect — a producer-side replay resetting the row for the next poll with the consumer's guard absorbing the duplicate, a subscriber-side replay reaching one (event, consumer) pair and no other with a late success absorbed by IInboxGuard, and a terminal job recovered by requeue. The /readyz criterion said "a registered check" while this change's own Deliverable names two checks and a serving window. It now reads both audit and outbox, reports unhealthy when either fails, and enforces the configured unhealthy-serving window. The routing-stop and /healthz liveness assertions are unchanged.
