118	## S7. Auth middleware (JWT validation) (LT-40)
119	
120	**Description:** The middleware at the `cmd/api-service` edge validating the client-credentials JWT scheme from `handoff-03-auth.md` v3 — public-key-only verification, `sub`/`scope`/`exp`/`iat`/`aud` claim checks, `kid`-based key rotation, no denylist (TTL-only revocation, a deliberate trade-off not to be re-litigated). Also covers the `APP_MODE=verifier|issuer` split (`PLANNING.md`) — this Deployment mode never mounts the signing key regardless of `APP_MODE`'s value, since `verifier` is this story's own code path and `issuer` is a separate mode of the same binary the F13 fix depends on to keep the two isolated by Deployment, not just by RBAC.
121	
122	**Acceptance criteria:**
123	- [ ] Implements 02's token scheme without re-deriving the no-refresh/no-denylist reasoning in `api-auth-design.md`.
124	- [ ] Rejects any token whose `aud` doesn't match this service's audience — enforcement site: the claim-validation step, with a unit test using a mismatched-audience token.
125	- [ ] Verifies with the public key only; the private signing key never touches this binary's code path — enforcement site: dependency/import check (no signing-key material referenced in `internal/api`).
126	- [ ] **Pins the expected signing algorithm and rejects any token whose header claims a different one**, including `alg: none` and a symmetric-algorithm downgrade using the public key as an HMAC secret (RFC 8725 §3.1) — enforcement site: explicit algorithm check in the JWT verification call, not left to the library's default (`handoff-03-auth.md` v3 names this as a common library footgun).
127	- [ ] The token-issuing endpoint (the `APP_MODE=issuer` mode) has its own failed-grant rate limiting and progressive backoff per `client_id` and per source IP, separate from the resource-API limits below, with alerting on a sustained run of failed grants against one `client_id` — enforcement site: issuer-mode middleware, distinct from the verifier-mode rate limiter (`handoff-03-auth.md` v3).
128	- [ ] Per-client-credential rate limits (60 req/min read, 10 req/min search) and the cumulative distinct-record-touch counter (rolling 24h) are enforced and alert on sustained near-limit usage, not just throttle — enforcement site: the rate-limit middleware plus its own test.
129	- [ ] The deadline budget for a request (context propagation into the DAO layer) is sized to cover realistic p99 DAO latency, per `decisions/context-propagation.md`'s ruling — stated as a concrete number in this story's implementation, not left as "some deadline."
130	
131	**Depends on:** S1; **02: Auth scheme and authorization hand-off** (`handoff-03-auth.md` v3, accepted); **04: `APP_MODE` Deployment split** (`containerization-design.md`, F13).
132	**Model/effort:** sonnet, high.
133	**Type:** Story.
134	**Labels:** `track-03`, `security-graded`, `no-code-yet`.

56:This is a real, not cosmetic, gap on infrastructure of this kind: everything else in this pair is carefully isolated for launch, but nothing addresses end-of-life. A take-home interview evaluation is time-bounded; a live namespace, a self-hosted runner with cluster-facing RBAC, a public HTTPS endpoint, and a JWT signing key are not, unless something says otherwise. Without a named teardown procedure and owner, the realistic failure mode is exactly the one production infrastructure tends to accumulate: isolation gets audited once at launch and then the whole thing is quietly forgotten, while its attack surface persists indefinitely. The trigger condition itself (when teardown actually happens — a fixed number of days after Warren confirms the interview process has concluded, or on request) is Warren's call, not this track's or this refinement's to set unilaterally — flagged to the PM below for that specific decision; this criterion only requires that the procedure exist and name an owner, not that it fire automatically on a date this refinement invents.
72:**Tobias Lindqvist — objection:** This pair specifies careful isolation for launch (namespace, RBAC, NetworkPolicy, ResourceQuota, scoped runner set) but nothing about end-of-life — no teardown procedure, no named owner, no trigger condition for decommissioning a take-home interview's infrastructure running on Warren's real production cluster indefinitely. The realistic failure mode is isolation audited once at launch and then forgotten while the attack surface (a self-hosted runner with cluster RBAC, a public endpoint, a signing key) persists. Counter-proposal accepted: added a teardown-procedure acceptance criterion; the trigger condition itself (when teardown fires) is flagged to the PM as Warren's call, not decided unilaterally here.

13:| Static API keys | Simple, but no expiry semantics, no scoping without inventing one, easy to leak into logs/URLs, no standard revocation flow | Rejected as the primary mechanism — acceptable only as a secondary, coarse-grained "which client system is this" identifier, never as sole authn/authz. |
25:- **No refresh tokens** for a client-credentials grant — the client re-authenticates with its own client secret when the access token expires. This bounds the blast radius of a leaked access token to its short TTL.
26:- **Revocation**: because JWTs are self-contained, true revocation requires either a short enough TTL that revocation is unnecessary in practice (the approach here) or a token-denylist check, which reintroduces a stateful lookup and defeats part of the point of JWTs. Given the 5–15 minute TTL, denylist is not required for this design; flagged here so a reviewer sees the trade-off was considered, not missed.
28:- **Bearer-token replay — named as an accepted risk explicitly, for consistency with the connector's token (S8 review, Tomasz Wrede).** This API's access tokens have the identical property S3 named for the connector's vendor token: bearer = possession-equals-authority, no proof-of-possession or session binding, for RFC 6750's stated reasons. **Accepted risk**, not a silent assumption: acceptable because the 5–15 minute TTL bounds the exposure window, and adding PoP (DPoP, RFC 9449) would be disproportionate complexity for a take-home's machine-to-machine API. Stated here so a reviewer doesn't have to infer why one token type in this project got an explicit accepted-risk line and the other didn't.
67:- **90-day re-approval** on every scope grant (not `profile:search` alone) is a backstop, not the only mechanism. Grants are revoked immediately, ahead of the 90-day cycle, on: the named approver's offboarding, the caller's stated business function changing, or an idle trigger (no usage for 30 days → revoke pending re-justification) — whichever comes first. This requires 03/04 to consume an offboarding or ownership-change signal; the requirement (lifecycle-triggered revocation, not solely calendar-triggered) is asserted here, the plumbing is theirs.
80:Worth stating plainly since it's the simplest alternative a reviewer might expect: a static API key has no expiry, no standard scope representation, and if it leaks (URL, log, repo) it's valid until manually rotated. The chosen design bounds leak exposure to minutes (token TTL) rather than "until someone notices," and expresses authorization natively instead of requiring a bespoke key→permissions side table. That trade costs implementation complexity (an authorization-server component, however minimal) which is why it's stated explicitly here rather than assumed.
84:Full record: `decisions/search-authz-scoping.md`. Ingrid Solano's five numbered objections against Helena Marsh's initial proposal, all accepted and revised into the sections above: (1) `read:any` was shaped before its actual callers were enumerated — fixed by requiring a caller-role table entry, gated like `search`; (2) `read:any`'s `reason_code` was freeform — fixed with a closed, versioned enum; (3) `caller_referral` membership had no owner or approval process, the softest control gating the narrowest scope — fixed by routing it through the same partner-onboarding workflow as any other grant; (4) per-request rejection and per-minute rate limits don't stop decomposition (slow enumeration under the cap) — fixed with a cumulative distinct-record-touch counter per rolling window; (5) 90-day re-approval is calendar-only, not lifecycle-tied — fixed with immediate revocation on offboarding, function change, or a 30-day idle trigger, with the 90-day cycle as backstop only.

  "content": "# LT-40 refinement — S7: auth middleware (JWT validation)\n\n**Product Owner:** Naomi Voss (01). **Research team:** Imogen Hale, Desmond Okafor, Tobias Lindqvist. **Engineering:** Renata Cole (03). **Source:** `03-engineering-delivery/backlog.md` S7 (LT-40); `02-ai-security-architecture/api-auth-design.md`, `handoff-03-auth.md` v3.\n\n**Who did the work:** Refined by Naomi Voss (PO); claims check Desmond Okafor; objection Tobias Lindqvist; engineering counterpart Renata Cole.\n\n## Why this one, now, and at priority\n\nThis is the critical path per team-lead's direction: LT-39's handlers are code-review-passed but deliberately unwired (exposing them before real auth exists would serve unauthenticated PII), LT-32's issuer split is deployed and live at `/auth/token` (currently a 501 placeholder), and LT-34's live-URL story stays open until something real is reachable through auth. This story is what turns all of that into an actual, reviewable, authenticated public endpoint.\n\n## Correction to `backlog.md`'s own story text, found before drafting\n\n**S7's acceptance criterion 6 (\"per-client-credential rate limits and the cumulative distinct-record-touch counter ... enforcement site: the rate-limit middleware plus its own test\") is stale relative to work already merged.** `backlog.md` was written before LT-39 (PR #26) implemented `RateLimiter` and `TouchCounter` as explicit, tested checks called *inside* each handler (via a `Deps` struct), not as separate HTTP middleware — confirmed by reading `internal/api/auth.go`, `handlers.go`, `ratelimit.go`, `touchcounter.go` directly. Both are already built, both are already tested (including the two hard-deny regression tests from LT-39's own refinement), and both are already wired to whatever `AuthContext` the request context carries.\n\n**What this means for LT-40's actual scope:** this story does **not** rebuild rate limiting or the touch counter. Its job is narrower and already well-seamed: verify the JWT, populate `AuthContext` (via `WithAuthContext`, already exported by `internal/api`) with the token's `sub` and `scope` claims, and wire the resulting middleware into `cmd/api-service`'s router ahead of the already-built handlers. The 90-day-re-approval/lifecycle-revocation machinery (`api-auth-design.md`) and the issuer-side rate limiting (criterion 5, below) are the only genuinely new rate-limit-shaped work this story adds — the resource-API limits are already done.\n\n## Acceptance outcome\n\n\"Done\" for this story specifically is the first fully authenticated, live, reviewable REST endpoint: a real client-credentials token obtained from `/auth/token` (once its actual issuance logic lands — see Non-goals) or, in the interim, a token minted directly against the deployed signing key for review purposes, presented to `/profiles/search` or `/profiles/{id}` at the public URL, producing a masked search response or a 401/403/429 exactly as LT-39's tests predict.\n\n## Acceptance criteria (restated from `backlog.md` S7, corrected per the finding above)\n\n- [ ] Implements 02's token scheme without re-deriving the no-refresh/no-denylist reasoning in `api-auth-design.md` — no refresh tokens (client re-authenticates on expiry); TTL-only revocation (5–15 min), no denylist, an explicitly accepted trade-off, not to be re-litigated.\n- [ ] Rejects any token whose `aud` doesn't match this service's audience — enforcement site: the claim-validation step, unit test with a mismatched-audience token.\n- [ ] Verifies with the public key only; the private signing key never touches this binary's code path — enforcement site: dependency/import check, no signing-key material referenced anywhere in `internal/api` or the verifier's own binary path (this is already structurally true per LT-32's Deployment split; this criterion confirms the *code*, not just the *Deployment*, never imports signing-key material).\n- [ ] **Pins the expected signing algorithm and rejects any token whose header claims a different one**, including `alg: none` and a symmetric-algorithm downgrade using the public key as an HMAC secret (RFC 8725 §3.1) — enforcement site: an explicit algorithm allowlist check in the JWT verification call, never left to the library's default. Unit tests: a token with `alg: none`, a token HMAC-signed using the public key bytes as the secret, both rejected.\n- [ ] `kid`-based key rotation: the middleware selects the verification key by the token's `kid` header claim, supporting at least two concurrently valid public keys during a rotation overlap window — enforcement site: a unit test presenting tokens signed under two different `kid`s, both verifying successfully when both keys are configured.\n- [ ] The middleware populates `internal/api.AuthContext` (via the already-exported `WithAuthContext`) with the token's `sub` and `scope` claims on success, and returns 401 (via LT-39's existing unauthorized-response path, not a new one) on any verification failure — **this is the actual integration seam with S6's work, not new response-shape design.**\n- [ ] The token-issuing endpoint (`APP_MODE=issuer`, currently the 501 placeholder from LT-32) gets its own failed-grant rate limiting and progressive backoff per `client_id` and per source IP, separate from the resource-API limits (which are already built in `internal/api`) — with alerting on a sustained run of failed grants against one `client_id`. This is genuinely new work, not already covered by LT-39.\n- [ ] The deadline budget for a request (context propagation into the DAO layer) is sized to cover realistic p99 DAO latency per `decisions/context-propagation.md`'s ruling — stated as a concrete number in this story's implementation, not left as \"some deadline.\"\n- [ ] The resource-API rate limiter and touch counter already built in LT-39 are wired to real, JWT-derived `AuthContext.Sub` values once this middleware populates them — **no new implementation, an integration check**: a live-URL test with a real token confirms the 60/10 req/min limits and the touch cap actually apply per real client identity, not per a test fake's hardcoded value.\n\n## Non-goals\n\n- **Real token issuance logic** (actually minting a signed JWT from valid client credentials at `/auth/token`) is explicitly out of scope for this story unless `backlog.md`/02 says otherwise — LT-32 only built the placeholder route and the signing-key custody; this story is the *verifier* side. Flagged as an open question below, since without it there's no way to obtain a real token for the live-URL review other than an out-of-band test token minted directly against the deployed key.\n- No change to `internal/api`'s handler logic, masking, or error translation — that's LT-39, already merged.\n- No change to the object-level `authorize()` policy datastore — still a stated seam (`Authorizer` interface), real implementation is a later story per `handoff-03-auth.md` v3's F8 resolution.\n- No client-credential provisioning UI/API for new callers — out of scope for this take-home entirely, per `01-product-industry-research-design`'s track boundary.\n\n## Open question, flagged before hand-off rather than discovered at review time\n\n**Is there a real token-issuance implementation planned before or alongside this story, or does the live-URL review use an out-of-band test token?** `backlog.md` doesn't have a separate story for `/auth/token`'s actual grant logic (validate client_id/client_secret, mint a signed JWT) — LT-32 only built the route as a 501 placeholder. If issuance isn't a planned story, the PO review script below needs an out-of-band way to mint a real token against the deployed signing key for review purposes, which is a meaningfully different (and less representative) review than \"call `/auth/token` for real.\" Flagging to Renata/team-lead now rather than discovering it when I try to run the review script.\n\n## PO review script\n\n1. Confirm the algorithm-allowlist and `kid`-rotation unit tests exist and pass — read the test names and assertions directly, not just \"tests pass.\"\n2. Confirm `AuthContext` population uses the already-exported `WithAuthContext`/`AuthContext` types from `internal/api`, not a parallel/duplicate type — grep for a second definition of anything auth-context-shaped.\n3. Confirm the issuer-side rate limiting is a distinct code path from the resource-API rate limiter already in `internal/api/ratelimit.go` — this is genuinely new work, shouldn't reuse or be confused with the existing one.\n4. Confirm the context-propagation deadline is a concrete, named number in code (e.g. a constant), not an inline magic value scattered across call sites.\n5. Once deployed and a real (or, per the open question above, out-of-band) token is available: hit `/profiles/search` and `/profiles/{id}` at the live URL, confirming a masked response, a 401 on a missing/expired/wrong-audience token, a 403 on a wrong-scope token, and — if enough calls are made — an actual 429 once the touch cap is crossed. This is the live-URL review LT-34/LT-39 have both been waiting on.\n\n## Research team review\n\n**Desmond Okafor — claims check:** [pending]\n\n**Tobias Lindqvist — objection:** [pending]\n\n**Naomi Voss — ruling:** [pending]\n"

15	**What this means for LT-40's actual scope:** this story does **not** rebuild rate limiting or the touch counter. Its job is narrower and already well-seamed: verify the JWT, populate `AuthContext` (via `WithAuthContext`, already exported by `internal/api`) with the token's `sub` and `scope` claims, and wire the resulting middleware into `cmd/api-service`'s router ahead of the already-built handlers. The 90-day-re-approval/lifecycle-revocation machinery (`api-auth-design.md`) and the issuer-side rate limiting (criterion 5, below) are the only genuinely new rate-limit-shaped work this story adds — the resource-API limits are already done.

Splitting them keeps each story reviewable on its own and matches how the work will actually land as commits.

138	## S8. Connector: /auth + /identity (Q3) (LT-41)
139	
140	**Description:** `cmd/idp-connector`'s outbound client and inbound handlers for the assignment's fixed `/auth` and `/identity` contracts, per `connector-security.md`'s no-cache-by-default token lifecycle (fetch per `/identity` call, discard on return; fresh isolated `Authorization` header per outbound request, never inherited from pooling/keep-alive; fetch → use-once → zeroize, retries re-fetch via `/auth`). Includes the connector's own inbound self-auth (distinct audience `idp-connector-service`, scope `connector:identity-lookup`, restricted to `api-service` as caller) per `handoff-03-auth.md` v3 §"Where it's validated" (Ingrid's S8 catch), and the `context.WithTimeout` + bounded pool + backoff requirement from `decisions/go-layout-debate.md`.
141	
142	**Acceptance criteria:**
143	- [ ] Implements 02's token-lifecycle spec (`connector-security.md`, `decisions/connector-token-lifecycle-redblue.md`) without re-litigating the no-cache-by-default posture.
144	- [ ] No vendor token is persisted or cached across requests by default; if a future exception is ever justified it requires re-review, not a silent default change — enforcement site: no storage/cache call in the token-fetch path.
145	- [ ] Every outbound vendor call sets `context.WithTimeout`; the outbound HTTP client uses a bounded connection pool; token-refresh retries back off rather than tight-looping — enforcement site: the HTTP client construction plus a test asserting a timeout fires.
146	- [ ] The connector's own `/auth`/`/identity` handlers validate an inbound JWT with `aud: idp-connector-service` and `scope: connector:identity-lookup`, distinct from `api-service`'s audience — enforcement site: this handler's own middleware instance, with a test asserting a `loginid-api-service`-audience token is rejected here.
147	- [ ] Never logs, in any environment or error path: the end-user's vendor password, any vendor `access_token` or full `Authorization` header value, or raw vendor error response bodies (per `handoff-04-secrets.md`'s never-log list) — enforcement site: log-call review against that list.
148	
149	**Depends on:** S1; **02: Connector security spec** (`connector-security.md`, accepted); **02: Auth scheme and authorization hand-off** (`handoff-03-auth.md` v3, accepted, for the connector's own self-auth).

156	## S9. Handler and connector unit tests (LT-42)
157	
158	**Description:** Table-driven unit tests for the handler layer (S6/S7, mocked DAO via S2's hand-written fakes) and the connector (S8, mocked HTTP), per `decisions/test-double-strategy.md`. The DAO's own cross-backend correctness is S5's job, not this story's — this covers request/response shape, auth rejection paths, and error-translation-to-HTTP-status mapping.
159	
160	**Acceptance criteria:**
161	- [ ] Test doubles are hand-written interface fakes, not a generated-mock library — per the ruling in `decisions/test-double-strategy.md`.
162	- [ ] Any change to `Repository` or its sub-interfaces updates the corresponding fake in the same PR — enforcement site: review checklist item, stated in this story's PR template/description.
163	- [ ] Handler tests cover every sentinel-to-HTTP-status mapping from `decisions/error-semantics.md`'s boundary translation function, including the unmapped-error-defaults-to-500-with-no-detail case.
164	- [ ] Connector tests cover the no-cache token-lifecycle assertions (a second `/identity` call re-fetches via `/auth`, never reuses a prior token) with mocked HTTP.

Token issuance: real `/auth/token` grant logic (LT-51)\n\n**Status: new** — created from Tobias's (01) objection during LT-40's refinement (`01-product-industry-research-design/refinement/LT-40.md`), which found the gap was unscheduled, not pending: LT-32 built `/auth/token`'s route (a 501 placeholder on the issuer Deployment) and LT-40 builds the verifier side, but nothing implemented the grant itself. Without it, \"done = deployed and reviewable at a public URL\" would have quietly weakened into \"reviewable by an engineer with cluster access\" — a materially different and less credible bar than the one this project has held since LT-34.\n\n**Description:** OAuth2 client-credentials grant at `POST /auth/token` on the issuer Deployment (`APP_MODE=issuer`), per Marcus's `handoff-03-auth.md` v4 addendum:\n- **Client authentication:** HTTP Basic, `client_id`/`client_secret`, form-encoded `client_credentials` grant per RFC 6749 §4.4.\n- **Client store:** the issuer's own datastore (not 05's schema — same F8 boundary as `caller_referral`), secrets hashed with Argon2id, never stored or logged in plaintext.\n- **Responses:** RFC 6749 §5.1 (success) / §5.2 (error) shape. An unknown `client_id` and a wrong secret for a known `client_id` return the **identical** `invalid_client` error — no oracle letting a caller distinguish \"doesn't exist\" from \"exists, wrong secret.\"\n- **Token:** short-lived RS256 JWT, `iss`/`aud`/`scope`/`exp`/`sub` claims per `handoff-03-auth.md` v3, algorithm/`kid` header per RFC 8725 pinning (matches LT-40's verifier-side allowlist). A `jti` claim is recommended for audit correlation only — **not** a revocation mechanism; TTL-only revocation stands per `api-auth-design.md`, not re-litigated here.\n- **Public-key distribution:** a JWKS endpoint served by the issuer's in-cluster `ClusterIP` `Service` — **no public `Ingress` route** for it; only the verifying middleware inside the cluster (LT-40) needs it, and exposing it publicly is unnecessary attack surface for a machine-to-machine API with no external relying parties.\n\n**Acceptance criteria:**\n- [ ] `POST /auth/token` implements RFC 6749 §4.4 client-credentials grant with HTTP Basic client auth and form-encoded body, without re-deriving 02's scheme reasoning in `handoff-03-auth.md` v4.\n- [ ] Client secrets are stored Argon2id-hashed in the issuer's own datastore; never logged, never returned in any response, never present in plaintext outside the initial provisioning step — enforcement site: log-call review against `handoff-04-secrets.md`'s never-log list, plus a test asserting the stored representation isn't the plaintext secret.\n- [ ] An unknown `client_id` and a wrong secret for a known `client_id` return byte-identical `invalid_client` error responses — enforcement site: a test comparing both response bodies for equality, not just \"both return 401.\"\n- [ ] The issued JWT's claims (`iss`, `aud`, `scope`, `exp`, `sub`) and algorithm/`kid` header match what LT-40's verifier middleware expects and validates — enforcement site: an integration test that mints a token here and verifies it through LT-40's actual middleware, not two independently-trusted unit tests that never touch each other.\n- [ ] The JWKS endpoint is served only on the issuer's in-cluster `ClusterIP` `Service`, with no `Ingress` route — enforcement site: manifest inspection (04's side) plus a test confirming the endpoint exists on the issuer's internal address.\n- [ ] **A dedicated, narrowly-scoped QA client credential is seeded in the client store specifically for the PO's live-URL review** (LT-34/LT-39/LT-40's joint acceptance) — provisioned out-of-band (same discipline as LT-32's signing-key `Secret`, never through the CI-applied manifest set), scoped to the minimum grant needed to exercise `profile:search`/`profile:read:own`/`profile:read:any`, and named/owned so it can be rotated or revoked independently of any real caller's credential.\n- [ ] This story's own failed-grant rate limiting/backoff (LT-40's criterion 5) applies to this endpoint's real implementation, not just the placeholder — confirmed by re-running LT-40's rate-limit tests against the real grant logic, not assumed to still hold.\n\n**Depends on:** S1; **02: Auth scheme hand-off v4 addendum** (`handoff-03-auth.md` v4, accepted); **LT-40** (the verifier this story's tokens must validate against); **04: JWKS `Service` exposure** (in-cluster only, no `Ingress` route).\n**Model/effort:** sonnet, high.\n**Type:** Story.\n**Labels:** `track-03`, `security-graded`, `from-consistency-pass`, `no-code-yet`.\n\n---\n\n## S8.

All LT-51/v4-addendum claims (RFC 6749 §4.4, identical `invalid_client`, Argon2id hashing, `jti` non-revocation, JWKS in-cluster-only, the no-out-of-band-signing ruling) verified word-for-word against `handoff-03-auth.md` v4. One footnote flagged to Renata separately, not a defect here: `decisions/context-propagation.md` cites its own ruling as living in \"S3's middleware design,\" using a numbering scheme that predates current `backlog.md` IDs (current S3 is LT-36, not this story) — LT-40.md doesn't repeat that stale label, but a future reader chasing \"S3\" there would land on the wrong story.\n\n**Tobias Lindqvist — objection:** The missing token-issuance logic wasn't a \"pending, scheduled\" gap like LT-36/37 waiting on LT-38 — it had no ticket at all, and treating an out-of-band token as this story's own review method would have quietly weakened \"done = reviewable at a public URL\" into \"done = reviewable by an engineer with cluster access,\" without anyone deciding that on purpose. Resolved: a new story (LT-51) was created rather than worked around, sequenced right after this one, with LT-40's live-URL review folded into LT-51's joint review using a real issued token — not a separate, lesser acceptance event.\n\n**Naomi Voss — ruling:** All fixes applied (status accuracy, header citation, the stray-numbering flag routed to Renata). This refinement is accepted and ready to hand off. Between this story and LT-51, the review chain caught something more consequential than a citation error: an entire missing story that a lesser process would have quietly worked around with a review shortcut, permanently softening the project's own \"done\" bar without anyone choosing that on purpose."

7:## Story 1 — Containerize `api-service` and `idp-connector` (LT-45)
9:**Description:** Build the two multi-stage Go images (distroless final stage, non-root, read-only root filesystem) and the Deployment/Service/NetworkPolicy manifests targeting the lab cluster, per `./containerization-design.md`. Covers both binaries' Dockerfiles, resource requests/limits sized per service (CPU-bound `api-service` vs. I/O-bound `idp-connector`), the migration `Job` (parallelism 1, gated by the CI pipeline's exclusivity mechanism, not Kubernetes ordering alone), a default-deny `NetworkPolicy` on `idp-connector` so its "no inbound Service" isolation claim actually holds against the namespace's default-allow network, and — per the consistency pass's F13 finding — a **third manifest**: `api-service-issuer`, a second Deployment of the same `api-service` image (`APP_MODE=issuer`) whose own ServiceAccount is the only one that mounts the JWT signing key, since RBAC on the `Secret` verb does nothing once it's volume-mounted into the verifying Deployment's replicas.
17:- [ ] The migration `Job` cannot start a second concurrent run — enforcement site: the CI pipeline's concurrency-gated deploy stage (Story 3), not a database lock.
20:**Depends on:** 03 — `cmd/api-service` and `cmd/idp-connector` build as real binaries (service boundaries already stable, per `PLANNING.md`); 05 — final migration tooling name for the `Job`'s invocation (already final, `05-data-ops/migration-approach.md`).
28:## Story 2 — Deliver secrets to both services per 02's inventory (LT-46)
30:**Description:** Implement the Kubernetes-native `Secret` delivery mechanism in `./secrets-delivery.md`: file-mounted secrets keyed by name only in manifests, RBAC scoped per-service (and, for the JWT signing key, scoped to the issuing code path specifically, not `api-service`'s verification path), cluster-level encryption-at-rest for the `Secret` resource type, and the migration-runner credential's backend-specific provisioning (`CREATE EXTENSION pg_trgm` rights on PostgreSQL only, nothing extra on CockroachDB, no privilege model on SQLite) kept distinct from the runtime service credential (DML-only, no DDL, per 05's R4).
36:- [ ] The migration-runner credential and the runtime service credential are provisioned as two distinct `Secret`s, never one — enforcement site: separate `Secret` objects, separate `Role`s, per 05's R4.
39:**Depends on:** 02 — `handoff-04-secrets.md` (received, v2, final); 05 — `migration-approach.md` R4 (final).
47:## Story 3 — CI/CD pipeline: build, lint, test, scan, migrate, describe-only deploy (LT-47)
49:**Description:** Stand up the pipeline in `./ci-pipeline.md`: build/lint/test(`-race`, three DB targets: SQLite, Postgres, CockroachDB)/security-scan/image-build on every PR; push-images/migration-job/describe-only-deploy on merge. The migration-job stage is where 05's R2 exclusivity requirement is actually enforced — a concurrency-gated pipeline stage, not a database lock, since no single lock mechanism covers both the right scope (session, to span `goose`'s per-file transactions) and the right engine (CockroachDB supports transaction-scope only).
55:- [ ] Only one migration run can reach the migrate stage at a time, across concurrent deploys — enforcement site: the pipeline's own concurrency group/mutex on the deploy environment.
59:**Depends on:** 03 — test-strategy outline for `go test ./...` to run against; 05 — `migration-approach.md` (final).
67:## Story 4 — Local dev-loop: compose profiles for SQLite and Postgres (LT-48)
73:- [ ] The `postgres` profile exercises the shared `postgres`-package code path (Postgres + CockroachDB) — enforcement site: compose service definition wiring `DB_DRIVER=postgres`.
85:## Story 5 — Observability: logging, metrics, never-log enforcement, retention-sweep alerting (LT-49)
104:## Story 6 — Configure log-sink retention for the audit trail (LT-20)

9:## 1. Tool: goose
11:**goose** — a Go command-line migration runner that applies numbered `.sql` files in order and records which have been applied in a version table inside the target database. Plain-SQL-first, minimal dependencies. Reasoning is in `./multi-db-strategy.md` and `./research-data-ops-best-practices.md` §3: this schema is "mostly shared DDL, occasionally per-backend", and goose's loose directory model fits that better than golang-migrate's stricter paired up/down files. golang-migrate is an equally defensible tool and I will not contest a swap if 03 already has tooling preferences — **nothing in §3–§6 below changes if the tool changes — with one named exception**: §2's two-invocation mechanism uses goose's `-table` flag, so a swap to golang-migrate means re-deriving how two independent version sequences are kept apart. That is the tool-independence claim's only load-bearing use, and pretending otherwise would be the kind of small overclaim this document is otherwise trying to avoid. Atlas is the schema-as-state alternative worth knowing about; it is more than this take-home needs.
13:Version numbering: timestamped filenames during development (avoids collisions when two branches add a migration), converted to a clean sequential 001/002/003 series with `goose fix` — the subcommand that renumbers timestamped files — **before the migrations have been applied anywhere that persists.** That cutoff is the important half: renumbering after application rewrites history the version table already records, so `goose fix` is a pre-first-application step, not a tidy-up before tagging. Not a decision 04 needs to act on — noted so nobody "fixes" the inconsistency later.
19:  shared/       # seed data only — no CREATE TABLE
31:**Corrected after the cross-track consistency pass (F28).** This section previously put every `CREATE TABLE` in `shared/`, with `postgres/` holding one index file. That was wrong, and wrong in a way the rest of this track's own work had already ruled out: the field-level schema in `multi-db-strategy.md` §5 gives **every** table per-engine DDL — `UUID DEFAULT gen_random_uuid()` vs `TEXT`, `TEXT COLLATE "C"` vs `TEXT COLLATE BINARY`, a regex `CHECK` vs a `GLOB` `CHECK`, `TIMESTAMPTZ` vs `TEXT`, `BYTEA` vs `BLOB`, `BOOLEAN` vs `INTEGER`. A single shared `CREATE TABLE` series cannot express that. SQLite's type affinity would quietly swallow the differing *type names*, which is what made the original claim look survivable, but it does nothing for collation clauses or CHECK syntax — those are hard syntax differences, not affinity.
33:The document already carried the right answer as a hypothetical fallback ("per-backend `CREATE TABLE` files and `shared/` reduced to seed data") and left it contingent on an open item marked "under review in story S1". **S1 closed, the review resolved it in favour of the fallback, and this document was not updated** — so a document marked "final" was carrying a provisional default that its own dependency had already overruled. That is the failure, and it is worse than the layout error: the fallback was correct, written down, and left unpromoted.
37:- **`shared/`** carries the `auth_method` seed row and nothing else. No `CREATE TABLE`.
45:**Nothing in §3–§6 changes, and neither does 04's design**, exactly as the earlier text promised: the two-invocation mechanism, the separate version tables, R1–R5 and the seed-data rule are untouched. R3's worked example still holds and in fact reads better now — a service can have `shared/` current with the `pg_trgm` index unapplied, which is why fail-closed must check both version tables. (`pg_trgm` is a PostgreSQL extension that indexes three-character fragments of text so that substring searches like `LIKE '%smith%'` can use an index instead of scanning every row — it is what makes name search fast. CockroachDB has the same capability built in; SQLite has no equivalent, so the index is omitted there rather than faked.). That parity gap is documented and deliberate (`./multi-db-strategy.md`); SQLite is the local/dev/demo backend, not a production peer.
47:**Mechanism 04 needs:** goose applies one directory per invocation, so a migration run is **two invocations — the backend directory FIRST, then `shared/`** — and each needs its own version table (`goose -table goose_db_version_<driver>`, then `-table goose_db_version_shared`). One shared table across two directories would interleave version numbers from independent sequences and corrupt the history. Both invocations must succeed for the run to count as successful.
49:> **Order corrected 2026-09-12 — it was inverted, and would have failed on a clean database.** This section originally said `shared/` then the backend directory. That was correct when `shared/` held the `CREATE TABLE`s. **Finding F28 moved all DDL into the per-backend directories and left `shared/` holding only the `auth_method` seed row — which inverted the dependency, and I did not revisit this sentence.** Running `shared/` first now means `INSERT INTO auth_method …` against a table that does not yet exist.
51:> Caught during review of LT-36's migration files, by reading the seed and the DDL together; it is invisible in either file alone and did not surface in 03's integration run, which applied the files in a working order rather than the documented one. **A green test suite is not evidence that the documented procedure works** — it is evidence that *some* procedure works.
57:**That open item is now closed.** It asked whether a single `shared/` DDL series survives all three backends, given that SQLite does not enforce column types the way PostgreSQL does — it assigns each column a loose "type affinity" and falls back to NUMERIC for any type name it does not recognise, `UUID` included. The answer turned out to be no, and for a reason narrower than type affinity: affinity would have absorbed the type names, but collation clauses and CHECK syntax differ outright. Resolved in favour of the per-backend split above. No open items remain in this document.
65:**The conclusion survives on a different and better reason: a transaction-scoped lock cannot cover a migration run.** `pg_advisory_xact_lock` is released when its transaction ends, and goose applies each migration file in its own transaction. The lock would therefore be released *between files*, letting a second runner interleave mid-run — which is precisely the failure it was supposed to prevent. Session-scoped locks, which would span the whole run, are the ones CockroachDB does not support. So the database can offer either the right scope or the right engine coverage, never both.
69:**A cheap portable backstop worth adding regardless — and an honest gap.** goose's version table is the one artifact all three backends share, so a unique constraint on its `version_id` would make a second concurrent runner fail on insert: portable, free, no platform feature required. **Whether goose's default version table already carries that constraint is unverified here** — I am not asserting it either way, because the objection that raised this correctly pointed out that the document claimed the database could not help without examining the one database-level mechanism goose already creates. The actionable form does not depend on the answer: **add a unique index on `version_id` ourselves in the first migration**, which is portable across all three backends and costs nothing if goose already does it. This is a backstop, not a replacement for R2 — it turns a silent interleave into a loud failure, which is the property actually worth buying.
71:**R3. The service fails closed when the schema is behind — checking BOTH version tables.** §2 creates two independent version sequences (`shared/` and the backend directory), so "the applied version" is two numbers, not one. The check must compare both, and must know which backend directory applies to the engine it is connected to. Checking only `shared/` would let a service pass with the `pg_trgm` index unapplied — caught by an objection turn, and it would have been a passing check that proved nothing. On startup the service compares both applied versions against the versions it was built against and refuses to serve if either is behind, rather than serving traffic against a schema missing a column it will query. The requirement is mine; whether the expected version is embedded at build time or derived from the migration files shipped in the image is 03's and 04's call.
79:**R4a. Applied migrations are immutable, and constraint changes need care on CockroachDB.** A correction to an already-applied migration is a **no-op** — goose does not re-run an applied version, so the live database keeps the old definition while the file looks correct. Corrections ship as a new numbered migration in every affected directory. Two consequences for the pipeline: verification must apply the *previous* state and migrate forward rather than building a fresh schema (a fresh build passes for an edited migration, which is how this hides), and **CockroachDB rejects a same-transaction `DROP` + `ADD` of a same-named constraint**, so those migrations carry `-- +goose NO TRANSACTION`. Established against live CockroachDB v23.2.0.
85:The `auth_method` table is seeded with one row, `"password"`. It ships as a migration file in `shared/`, not as a runtime bootstrap in the service — a service that writes its own lookup rows on boot is a service that can write them wrongly, concurrently, on every replica.
87:Idempotent via `INSERT ... ON CONFLICT (name) DO NOTHING`, which the unique constraint on `auth_method.name` already supports and which all three backends accept (the same portable upsert form the DAO uses — see `./multi-db-strategy.md`). goose will not re-run an applied migration anyway; the `ON CONFLICT` makes the file safe against a database someone seeded by hand, which in practice is how this breaks.
93:Named so 04 does not read a boundary into this doc that isn't there: where the databases actually run; how the pipeline invokes goose; environment topology and how many of them there are; backup schedule and retention of backups; connection pooling; monitoring of migration runs. All 04's. This document says *what must be true* about migration execution and *why*, and stops there.

  "content": "# New story refinement — deploy real Postgres in `loginid-takehome`, wire migrations, DB_DSN_FILE\n\n**Product Owner:** Naomi Voss (01). **Research team:** Imogen Hale, Desmond Okafor, Tobias Lindqvist. **Engineering:** Theo Bergman (04, owner); Priya Nandakumar (05, reviewer). **Source:** gap found during LT-40 refinement — none of `04-infra-devops/backlog.md`'s existing stories (LT-45/46/47/48/49/LT-20) actually deploy a running database instance; they all assume a DB target already exists. **Jira key:** pending team-lead creating it under Epic LT-4.\n\n**Who did the work:** Refined by Naomi Voss (PO); claims check Desmond Okafor; objection Tobias Lindqvist; engineering owner Theo Bergman; reviewer Priya Nandakumar.\n\n## Why this one, now\n\nLT-39's handlers are code-review-passed but there's nothing behind the DAO in the live cluster — no database, no applied schema, no seed data. This is the last missing piece before LT-34/LT-39/LT-40/LT-51's joint live-URL review can exercise a real search/retrieve call against real (if empty) data, not just an auth-and-routing check.\n\n## What this story is\n\nA single-replica PostgreSQL `StatefulSet` in the `loginid-takehome` namespace (Theo's call, confirmed: a managed instance would be disproportionate infra/cost for this take-home's scale; a single `StatefulSet` + `PersistentVolumeClaim` is the standard minimal shape and matches this project's existing \"small, isolated, no HA beyond what's needed\" pattern), a DB credential `Secret` provisioned out-of-band (same discipline as LT-32's JWT signing key — never through the CI-applied manifest set), a migration `Job` that runs goose against it in the correct two-invocation order before `api-service`'s rollout, and `DB_DSN_FILE` wired into `api-service`'s config so it actually connects to this database instead of erroring on an unset DSN.\n\n**Explicit scope limit, stated up front:** CockroachDB is exercised in CI only (LT-47's testcontainer job, against the shared `postgres`-package code path) and is **not** deployed anywhere in this cluster. Only PostgreSQL runs live. This is a deliberate scope limit for a take-home demo, not an oversight — stated here so a reviewer doesn't reasonably expect to find CockroachDB running somewhere and conclude something's missing.\n\n## Acceptance criteria\n\n- [ ] A single-replica PostgreSQL `StatefulSet` (with a `PersistentVolumeClaim` for data persistence across pod restarts) runs in `loginid-takehome`. Enforcement site: the `StatefulSet` manifest and its `Service`.\n- [ ] The DB credential (connection string / password) is provisioned out-of-band, never through the CI-applied manifest set — matching the pattern `deploy/issuer-secret-bootstrap.yaml` already established for the JWT signing key. Enforcement site: the credential `Secret` is absent from `deploy/manifests.yaml`; a bootstrap doc/script analogous to `issuer-secret-bootstrap.yaml` documents how it's created.\n- [ ] Per `05-data-ops/migration-approach.md` R4, the migration-runner credential (DDL rights, plus `CREATE EXTENSION pg_trgm` on Postgres specifically) and the runtime service credential (DML-only, no DDL) are two distinct `Secret`s, never one — matching LT-46's own criterion for this same split, applied here against a database that now actually exists.\n- [ ] The migration `Job` runs goose in the **correct, corrected order**: the backend directory (`postgres/`, containing the actual `CREATE TABLE` DDL) **first**, then `shared/` (seed data only, currently just the `auth_method` \"password\" row) **second** — per `migration-approach.md`'s own corrected ordering (the original text had this inverted, caught reading the seed and DDL together, not caught by a green test suite that happened to apply files in a different working order). Enforcement site: the `Job`'s invocation script/command, explicitly two `goose` invocations in this order, each against its own version table (`goose_db_version_postgres`, `goose_db_version_shared`) per R4's two-independent-sequences requirement.\n- [ ] Both goose invocations must succeed for the migration `Job` to count as successful — a partial success (backend DDL applied, `shared/` seed failed, or vice versa) is a failed `Job`, not a partial pass. Enforcement site: the `Job`'s script exits non-zero if either invocation fails.\n- [ ] The migration `Job` runs to completion **before** `api-service`'s rollout — enforcement site: deploy pipeline ordering (readiness gate or explicit sequencing in the merge-to-main workflow), not an assumption that Kubernetes scheduling happens to land in the right order.\n- [ ] `DB_DSN_FILE` (already a config surface `internal/config` supports per `PLANNING.md`'s Service boundaries) is wired to point at the runtime service credential's mounted file — `api-service` connects successfully on startup instead of erroring on an unset/placeholder DSN. Enforcement site: `api-service`'s Deployment manifest, mounting the runtime credential and setting `DB_DSN_FILE` to its path; a startup log line or health-check state confirming a live DB connection (not just that the env var is set).\n- [ ] `deploy/manifests.yaml`'s header comment (which currently states \"no migration Job, no DB_DSN secret — those wire up config the current code doesn't use yet\") is updated to reflect that this is no longer true, so a future reader isn't misled by a stale comment.\n- [ ] **`ResourceQuota` headroom confirmed for the new StatefulSet pod before merge** — added per Theo's own flag, given the earlier `api-service-issuer` `FailedCreate` incident from under-sized quota. Enforcement site: the quota math is shown in the PR description (current `limits.cpu`/`limits.memory` vs. the new total including Postgres's request/limit), and the `ResourceQuota` object is adjusted in the same PR if needed — not discovered as a second `FailedCreate` after merge.\n\n## Non-goals\n\n- No CockroachDB deployment — CI-only, per the explicit scope limit above.\n- No backup/restore, replication, or HA for Postgres — single replica, single PVC, take-home scale; `migration-approach.md` explicitly leaves backup schedule/retention as 04's call and out of this document's scope, and this story doesn't add it either.\n- No connection pooling (e.g., PgBouncer) — direct connections from `api-service` are sufficient at this scale; flag if load testing ever suggests otherwise.\n- No change to the migration file contents themselves (DDL, seed data) — that's 05's `migration-approach.md` and the actual `.sql` files, already written; this story only runs them.\n\n## PO review script\n\n1. Confirm the `StatefulSet` and its `PersistentVolumeClaim` exist in the manifest, targeting `loginid-takehome`.\n2. Confirm the DB credential `Secret` is absent from `deploy/manifests.yaml` and documented as provisioned out-of-band, matching the JWT-signing-key pattern.\n3. Confirm two distinct `Secret`s exist for the migration-runner vs. runtime credentials, with different RBAC scoping (DDL-capable vs. DML-only).\n4. Read the migration `Job`'s script directly: confirm two `goose` invocations, backend directory first, `shared/` second, each with its own `-table` flag, and that the script fails if either invocation fails.\n5. Confirm the deploy pipeline sequences the migration `Job` to completion before `api-service`'s rollout — not merely \"applied at some point.\"\n6. Once deployed: confirm `api-service` actually connects (a startup log line or health-check field, not just an unset-DSN error going away), and run a real `profile:search`/`profile:read:own` call through the live URL (joint with LT-40/LT-51's review) confirming it reaches real Postgres and returns a real (even if empty) result set — this is the actual proof this story exists to provide.\n7. Confirm the quota math was shown and the `ResourceQuota` adjusted if needed, before merge — not discovered as a `FailedCreate` after.\n\n## Research team review\n\n**Desmond Okafor — claims check:** [pending]\n\n**Tobias Lindqvist — objection:** [pending]\n\n**Naomi Voss — ruling:** [pending]\n"

19:- [ ] A single-replica PostgreSQL `StatefulSet` (with a `PersistentVolumeClaim` for data persistence across pod restarts) runs in `loginid-takehome`. Enforcement site: the `StatefulSet` manifest and its `Service`.
20:- [ ] The DB credential (connection string / password) is provisioned out-of-band, never through the CI-applied manifest set — matching the pattern `deploy/issuer-secret-bootstrap.yaml` already established for the JWT signing key. Enforcement site: the credential `Secret` is absent from `deploy/manifests.yaml`; a bootstrap doc/script analogous to `issuer-secret-bootstrap.yaml` documents how it's created.
21:- [ ] Per `05-data-ops/migration-approach.md` R4, the migration-runner credential (DDL rights, plus `CREATE EXTENSION pg_trgm` on Postgres specifically) and the runtime service credential (DML-only, no DDL) are two distinct `Secret`s, never one — matching LT-46's own criterion for this same split, applied here against a database that now actually exists.
22:- [ ] The migration `Job` runs goose in the **correct, corrected order**: the backend directory (`postgres/`, containing the actual `CREATE TABLE` DDL) **first**, then `shared/` (seed data only, currently just the `auth_method` "password" row) **second** — per `migration-approach.md`'s own corrected ordering (the original text had this inverted, caught reading the seed and DDL together, not caught by a green test suite that happened to apply files in a different working order). Enforcement site: the `Job`'s invocation script/command, explicitly two `goose` invocations in this order, each against its own version table (`goose_db_version_postgres`, `goose_db_version_shared`) per R4's two-independent-sequences requirement.
23:- [ ] Both goose invocations must succeed for the migration `Job` to count as successful — a partial success (backend DDL applied, `shared/` seed failed, or vice versa) is a failed `Job`, not a partial pass. Enforcement site: the `Job`'s script exits non-zero if either invocation fails.

67	## Story 4 — Local dev-loop: compose profiles for SQLite and Postgres (LT-48)
68	
69	**Description:** Build the `docker-compose.yml` in `./local-dev-loop.md`: `sqlite` and `postgres` profiles matching 03's `DB_DRIVER` env var, a mock/local `idp-connector` target, hot-reload (`air`) for `api-service` in dev profiles only, and local-only dev credentials clearly distinguished from the real secrets mechanism (Story 2).
70	
71	**Acceptance criteria:**
72	- [ ] A new developer can run either profile from this file alone, without asking what `DB_DRIVER` values are valid.
73	- [ ] The `postgres` profile exercises the shared `postgres`-package code path (Postgres + CockroachDB) — enforcement site: compose service definition wiring `DB_DRIVER=postgres`.
74	- [ ] Dev credentials never appear in `./secrets-delivery.md`'s mechanism or in any real manifest — enforcement site: explicit statement in the file plus separate variable naming (`dev`/`dev`, hardcoded client id/secret).
75	- [ ] Hot-reload has zero effect on the production image build — enforcement site: `air` target scoped to compose dev profiles only, never `./containerization-design.md`'s Dockerfile.
76	
77	**Depends on:** 03 — `DB_DRIVER`/config-surface env vars (already stable, per `PLANNING.md`).

104	## Story 6 — Configure log-sink retention for the audit trail (LT-20)
105	
106	**Description:** The consistency pass (`../decisions/cross-track-consistency.md`, "Deletion gap") ruled the enforcement site: a subject-deletion request reaches `user_profile`/`user_credential` by cascade but not application logs, metrics, or the audit trail, none of which has a `source` column or a deletion hook. 02's never-log list is the upstream control (PII values never enter a log in the first place, per `./observability.md`'s enforcement mechanism), which leaves exactly one remaining artifact needing a retention window: the audit trail itself (`sub`, scope, opaque record id, timestamp) — pseudonymous, not PII-free, and after a profile deletion the only remaining record that a given record id was looked up by a given caller. The enforcement site for its expiry is a retention policy on the log sink 04 already operates (Loki or equivalent, per `./observability.md`'s "Audit-log access" section) — not a deletion job, not a DAO method. 05 adds one row to `pii-governance.md`'s retention table for the audit-log window (basis: unknown, pending legal); 02 adds the two vocabulary/list fixes the pass identified for the never-log list (driver-error detail, `username`). This story configures the sink's retention setting to that window once it's a number.
107	
108	**Acceptance criteria:**
109	- [ ] The hand-off standard: 02 and 05 can each confirm their half (never-log list scope; retention-table row) without needing this story rewritten.
110	- [ ] The audit-log stream expires no later than 05's stated window — enforcement site: the log sink's retention configuration (a Loki `retention_period` or equivalent for the chosen sink), not application code.
111	- [ ] The retention configuration is separate from, and does not touch, any other log stream's retention or any Secret-access RBAC (`./secrets-delivery.md`) — enforcement site: sink-level retention is scoped per log stream/index, not global.
112	- [ ] Confirmed this is a configuration value, not a deletion job: no new DAO method, no new `cmd/` entrypoint, no scheduled job beyond what `./observability.md`'s retention-sweep story (Story 5) already covers for `user_profile`/`user_credential`-derived data.
113	
114	**Depends on:** 02 — never-log list additions (driver-error detail, `username`) confirmed; 05 — `pii-governance.md` audit-log retention-window row (basis: unknown, pending legal, per the pass).
115

Without it, LT-39's handlers have nothing real behind the DAO, and LT-34/LT-39/LT-40/LT-51's joint live-URL review can't exercise a genuine data path. Full refinement: `04-infra-devops/refinement/postgres-in-namespace.md`.\n\n**Description:** A single-replica PostgreSQL `StatefulSet` (with a `PersistentVolumeClaim`) in `loginid-takehome` — a managed instance would be disproportionate infra/cost for this take-home's scale, and a single `StatefulSet` matches this project's existing \"small, isolated, no HA beyond what's needed\" pattern (Theo's call, confirmed). Plus: a DB credential `Secret` provisioned out-of-band per the pattern already established for the JWT signing key (`deploy/issuer-secret-bootstrap.yaml`); the two-invocation goose migration `Job` in the corrected order (backend directory first, then `shared/`, per `05-data-ops/migration-approach.md`'s own corrected ordering); and `DB_DSN_FILE` wiring so `api-service` actually connects. **CockroachDB is explicitly out of scope for deployment** — it's exercised in CI only (LT-47's testcontainer job), never deployed live in this cluster; stated here so a reviewer doesn't expect to find it running.\n\n**Acceptance criteria:**\n- [ ] Single-replica PostgreSQL `StatefulSet` + `PersistentVolumeClaim` running in `loginid-takehome`.\n- [ ] A default-deny `NetworkPolicy` scopes Postgres's ingress to `api-service` (and the migration `Job`'s pod) only — matching `idp-connector-default-deny`'s existing shape, not the namespace's default-allow.\n- [ ] DB credential `Secret` provisioned out-of-band, never through the CI-applied manifest set — same discipline as the JWT signing key.\n- [ ] Migration-runner credential (DDL rights) and runtime service credential (DML-only, cannot run DDL) are two distinct `Secret`s — enforcement site: the runtime role's Postgres grants exclude `CREATE`/`ALTER`/`DROP`, verified by a failed DDL attempt under that role.\n- [ ] Migration `Job` runs goose in the corrected order — backend directory (`postgres/`) first, `shared/` second — each against its own version table (`goose_db_version_postgres`, `goose_db_version_shared`); both invocations must succeed for the `Job` to count as successful.\n- [ ] The migration `Job` is idempotent — a re-run against an already-migrated database applies zero new versions and exits successfully, not an error.\n- [ ] The migration `Job` completes before `api-service`'s rollout — deploy pipeline ordering, not assumed Kubernetes scheduling.\n- [ ] `DB_DSN_FILE` (not `DB_DSN`) is set in `api-service`'s live Deployment, pointing at the mounted runtime credential — precedence exercised in the running pod, not only in `internal/config`'s existing unit test.\n- [ ] `/healthz` reflects real DB connectivity as a boolean/enum field only (consistent with 02's existing ruling on the endpoint's response shape) — never a connection string, host, port, or driver `DETAIL` text, even when the DB is unreachable.\n- [ ] `deploy/manifests.yaml`'s header comment (currently: \"no migration Job, no DB_DSN secret\") is updated to match reality.\n- [ ] `ResourceQuota` headroom for the new `StatefulSet` pod confirmed and adjusted in the same PR if needed — shown in the PR description, not discovered as a second `FailedCreate` (per the `api-service-issuer` incident).\n\n**Depends on:** 03 — `api-service`'s `DB_DSN_FILE` config surface (already stable); 05 — `migration-approach.md` (final, corrected ordering).\n**Blocks:** LT-39's live-URL review (joint with LT-40/LT-51).\n**Model/effort:** Sonnet, medium.\n**Type:** Story.\n**Labels:** `track-04`, `security-graded`."

  "new_string": "**Desmond Okafor — claims check:** Verified the goose two-invocation ordering claim near-verbatim against `migration-approach.md`'s \"Mechanism 04 needs\" section, including the \"corrected order\" framing (not an overstatement — the source's own correction note matches the doc's compression of it faithfully). Verified the R4 credential-split claim exactly, including the Postgres-specific `pg_trgm` carve-out. Verified \"matching LT-46's own criterion\" is not a loose analogy — checked `04-infra-devops/backlog.md` directly, LT-46 states the identical requirement verbatim. No corrections needed.\n\n**Tobias Lindqvist — objection:** Raised that Postgres — the first component in this namespace actually holding PII at rest — had no stated `NetworkPolicy`, the same class of miss as the JWT-signing-key RBAC gap from LT-32. Objection was based on an earlier copy of this doc, sent before the Jira ticket's NetworkPolicy criterion was incorporated — the criterion (default-deny scoped to `api-service` + the migration `Job`'s pod selector, matching `idp-connector`'s pattern) was already present by the time he reviewed. Confirmed to him directly. His broader process point stands independently: this is the second time a new stateful/secret-bearing component needed a research-team catch on network/access scoping — flagged to Theo as a candidate standing checklist item, not decided unilaterally here.\n\n**Naomi Voss — ruling:** This refinement is accepted and ready to hand off. Both reviewers' passes came back clean on the doc as it stands; Tobias's process observation (recurring category of miss across two stories) is valuable independent of this instance already being covered, and has been routed to Theo for a process decision rather than folded into this story's own criteria."

Already created against the real cluster.\n- `api-service`'s Deployment split into its own file (`deploy/api-service.yaml`) so the deploy workflow can apply it only after the migration Job completes.\n- `ResourceQuota` bumped with the math shown in the PR (per the LT-32 `FailedCreate` lesson, now a standing checklist item in `containerization-design.md` §5a).\n- `deploy/rbac.yaml`: added `statefulsets`/`configmaps`, and `delete` on `jobs` (immutable pod templates require deleting the old Job before applying a new image tag).\n\n## Who did the work\nTheo Bergman (04 Infra lead).\n\n## Test plan\n- [x] Both manifest files validated with `kubectl apply --dry-run=server` against the real cluster\n- [x] RBAC change and the three Secrets already applied/created against the real cluster (key material never echoed)\n- [ ] First real deploy: Postgres comes up, migration Job completes in the right order and is idempotent on redeploy, `api-service` connects using `DB_DSN_FILE`\n\n🤖 Generated with [Claude Code](https://claude.com/claude-code)","files":[{"path":".github/workflows/deploy.yml","additions":40,"deletions":5,"changeType":"MODIFIED"},{"path":"deploy/api-service.yaml","additions":43,"deletions":0,"changeType":"ADDED"},{"path":"deploy/db-secret-bootstrap.yaml","additions":47,"deletions":0,"changeType":"ADDED"},{"path":"deploy/manifests.yaml","additions":152,"deletions":47,"changeType":"MODIFIED"},{"path":"deploy/migrate/Dockerfile","additions":12,"deletions":0,"changeType":"ADDED"},{"path":"deploy/rbac.yaml","additions":6,"deletions":3,"changeType":"MODIFIED"}]}

  "message": "Found a real, confirmed bug in PR #29's initdb script — not a style note, this would break the first real deploy. Postgres 15+ revoked PUBLIC's implicit CREATE grant on the `public` schema; only the schema owner (and superusers) can create objects there by default. Your init script grants `migrator` CREATEDB and \"ALL PRIVILEGES ON DATABASE\" but never grants CREATE on the `public` schema itself — database-level privileges and schema-level privileges are separate things in Postgres.\n\nI verified this in a live postgres:16-alpine container, not just reading docs: ran your exact CREATE ROLE/GRANT/ALTER DEFAULT PRIVILEGES sequence, then tried `CREATE TABLE t (id int);` as `migrator` — got `ERROR: permission denied for schema public`. Added one line — `GRANT CREATE ON SCHEMA public TO migrator;` — and the same CREATE TABLE succeeded immediately after. That's the fix: add that grant to `01-create-roles.sh` right after the migrator role/database grants, before the ALTER DEFAULT PRIVILEGES line.\n\nThis is exactly the class of bug `kubectl apply --dry-run=server` can't catch — it validates the Kubernetes objects, not whether the SQL inside the ConfigMap actually works against a real database. Worth adding \"run the migration Job against a real ephemeral Postgres in CI, not just dry-run the manifests\" as a lesson for next time, similar to how LT-32's manifest-boundary catch became a standing checklist item.\n\nEverything else in the PR (NetworkPolicy scope, three-Secret split, goose ordering/idempotency, api-service sequencing, quota math) I'm still reviewing — will report the rest once I've been through it, but wanted to flag this one immediately since it'd fail your very next real deploy.",

**Tobias Lindqvist — objection:** Raised that Postgres — the first component in this namespace actually holding PII at rest — had no stated `NetworkPolicy`, the same class of miss as the JWT-signing-key RBAC gap from LT-32. Objection was based on an earlier copy of this doc, sent before the Jira ticket's NetworkPolicy criterion was incorporated — the criterion (default-deny scoped to `api-service` + the migration `Job`'s pod selector, matching `idp-connector`'s pattern) was already present by the time he reviewed. Confirmed to him directly. His broader process point stands independently: this is the second time a new stateful/secret-bearing component needed a research-team catch on network/access scoping — flagged to Theo as a candidate standing checklist item, not decided unilaterally here.

**Naomi Voss — ruling:** This refinement is accepted and ready to hand off. Both reviewers' passes came back clean on the doc as it stands; Tobias's process observation (recurring category of miss across two stories) is valuable independent of this instance already being covered, and has been routed to Theo for a process decision rather than folded into this story's own criteria.

Both reviewers' passes came back clean on the doc as it stands; Tobias's process observation (recurring category of miss across two stories) is valuable independent of this instance already being covered, and has been routed to Theo for a process decision rather than folded into this story's own criteria.\n\n## PO acceptance review — PR #29\n\n**Reviewer:** Naomi Voss (PO). **Date:** 2026-09-13. **PR:** `https://github.com/wtvamp/loginid-takehome/pull/29`.\n\n**Blocking defect found and confirmed empirically, not from reading alone.** Postgres 15+ revoked `PUBLIC`'s implicit `CREATE` grant on the `public` schema — only the schema owner and superusers get it by default. The `01-create-roles.sh` initdb script grants `migrator` `CREATEDB` and \"ALL PRIVILEGES ON DATABASE,\" but never grants schema-level `CREATE` — a database-level grant and a schema-level grant are different things in Postgres. I ran a real `postgres:16-alpine` container, replayed the script's exact `CREATE ROLE`/`GRANT`/`ALTER DEFAULT PRIVILEGES` sequence, then attempted `CREATE TABLE t (id int);` as `migrator`: **`ERROR: permission denied for schema public`**. Confirmed the fix in the same container — one line, `GRANT CREATE ON SCHEMA public TO migrator;` — after which the same `CREATE TABLE` succeeded. Also confirmed `CREATE EXTENSION IF NOT EXISTS pg_trgm` (the first migration's other DDL statement) succeeds with the same single fix, since `pg_trgm` is a \"trusted\" extension (installable by any role with schema-level `CREATE`, not just a superuser) as of Postgres 13. This would have failed the very first real deploy, and `kubectl apply --dry-run=server` cannot catch it — it validates Kubernetes objects, not the SQL inside a `ConfigMap`.\n\n**Everything else checked out clean, verified directly against the diff, not summarized from the PR description:**\n- `StatefulSet` + `PersistentVolumeClaim` + headless `Service`: present, correctly shaped.\n- Default-deny `NetworkPolicy` on Postgres, ingress scoped to exactly `api-service` and the migration `Job`'s pod label — matches `idp-connector`'s pattern exactly, and a bonus: a matching `NetworkPolicy` was also added for `api-service-issuer` (in-cluster JWKS callers + `ingress-nginx` for the public `/auth/token` route), proactively applying the new §5a checklist beyond this story's own scope.\n- Three `Secret`s provisioned out-of-band (`db-secret-bootstrap.yaml`) — confirmed absent from `deploy/manifests.yaml`; `deploy/rbac.yaml`'s `Role` still grants nothing on `secrets`.\n- Migration-runner vs. runtime credential split confirmed as two distinct `Secret`s with distinct roles; runtime's lack of DDL rights is real (once the above fix lands) — `ALTER DEFAULT PRIVILEGES` correctly grants DML-only to `runtime` on tables `migrator` creates.\n- goose invocation order confirmed correct against the actual `migrations/` directory structure (`postgres/` then `shared/`, matching the real file layout, not just the doc's claim), each with its own `-table` flag; both must succeed (`set -e` in the Job's shell script).\n- Idempotency: goose's own applied-version tracking plus the seed's `ON CONFLICT DO NOTHING` — by construction, matches the criterion.\n- `api-service` correctly split into its own manifest and sequenced after the migration `Job` completes (`kubectl wait --for=condition=complete`), not assumed ordering.\n- Quota math shown in the manifest's own comment, itemized per component, matching the PR description exactly.\n- `deploy/manifests.yaml`'s header comment updated to reflect LT-52, no longer stale.\n- Health-endpoint DB-connectivity field confirmed as a separate, paired PR from Renata (03) — correctly not claimed as done here.\n\n**Verdict: blocked on one confirmed defect, otherwise ready.** Reported to Theo with the exact fix and the empirical verification. Re-reviewing once pushed; everything else above stands and won't need re-checking."

The `runAsNonRoot: true, runAsUser: 70, runAsGroup: 70, fsGroup: 70` fix is correct and matches the same class of issue LT-45's distroless images already had to solve.\n- **`goose` genuinely supports `GOOSE_DRIVER`/`GOOSE_DBSTRING`/`GOOSE_MIGRATION_DIR` as environment variables**, not just CLI args — confirmed by building the actual pinned version (`goose@v3.22.1`) in a real container and reading its own `--help` output, which documents exactly this env-var form. The DSN (containing a password) genuinely never appears in `ps` output inside the pod with this change — a real improvement over the prior positional-argument form, matching the discipline `DB_DSN_FILE` already uses for `api-service`.\n- **The sequences/UUID caveat comment is accurate and appropriately scoped** — the schema is UUID-keyed throughout (confirmed against `multi-db-strategy.md` in an earlier pass), so `ALTER DEFAULT PRIVILEGES ... ON TABLES` genuinely has no live sequence gap today; the comment correctly states this as a latent (not active) risk for a future `SERIAL`/`IDENTITY` column, not a defect needing a fix now.\n- **The `kubectl wait` → explicit poll-loop replacement is a real, well-reasoned fix**, not just defensive rewriting: `kubectl wait --for=condition=complete` doesn't fail fast on a `Failed` Job — it waits out the full timeout regardless, then exits as a timeout rather than a detected failure. The safety property (blocking `api-service`'s apply) held either way, but the poll loop makes a genuine migration failure surface in seconds instead of the full 180s timeout, and dumps the Job's logs on failure. The word-boundary match (`case \" $conditions \" in *\" Complete \"*)`) is the correct way to test membership in Kubernetes' space-separated multi-condition string — a plain `=` comparison, as the inline comment notes, would never have matched.\n- **TLS on the Postgres connection (`sslmode=require`, a self-signed `cert-manager` `Issuer`/`Certificate`)** — this is Marcus's ruling (`threat-model.md` Assumption 9), consistently applied with the client-facing TLS requirement one hop earlier. I did not independently stand up cert-manager to re-verify the handshake myself (a heavier repro than the container tests above), so this one line item rests on Theo's own reported end-to-end scratch-namespace test (TLS on, migrator creates tables, runtime blocked from DDL, both goose invocations succeed) rather than my own empirical confirmation — flagged honestly rather than claimed as independently verified.\n\n**Verdict: PASSES.** The one blocking defect from my prior pass is fixed and independently re-confirmed; every other change since then is either independently verified by me directly (UID, goose env vars, poll-loop logic, sequences caveat) or, for the one item I couldn't cheaply re-verify myself (the TLS handshake), honestly attributed to Theo's own reported test rather than claimed as mine.

}

3:Status: **v6** — fixes the JWKS path/URL and cache/refresh guidance (below), ruled so LT-51 implements to this doc rather than the doc following PR #30's already-shipped code. v5's Authorizer stand-in and cumulative-cap answers are unchanged. Receiver: Renata Cole, `../03-engineering-delivery/`. Written so 03 should be able to scaffold and build the middleware without re-deriving the reasoning in `api-auth-design.md`, `connector-security.md`, or the S3/S4/S8 decision records. Full reasoning, if wanted: `api-auth-design.md`, `decisions/search-authz-scoping.md`, `decisions/connector-token-lifecycle-redblue.md`.
21:**Response, errors (RFC 6749 §5.2, never distinguishing *why* in body or status):** `invalid_client` (401, `WWW-Authenticate: Basic`) for any client-authentication failure — unknown `client_id` and wrong `client_secret` get the **identical** response, same user-enumeration discipline already required elsewhere in this document; `invalid_scope` (400) if the requested scope isn't a subset of the client's granted scopes; `unsupported_grant_type` (400) for anything but `client_credentials`. Token-endpoint brute-force protection (rate limit + backoff per `client_id`/IP, already specified above) applies here, at this exact endpoint.
23:**Client store — issuer's own datastore** (per F8/row #4 of `handoff-04-secrets.md`, not 05's schema): `client_id`, `name` (accountability, per S4's provisioning bar — no shared credentials across a team), `client_secret_hash` (**Argon2id, same floor as `threat-model.md` Asset 1** — identical hashing discipline to password storage, not a separate algorithm choice to justify), `granted_scopes` (the provisioned subset of `profile:read:own`/`profile:read:any`/`profile:search`/`connector:identity-lookup`, per each scope's provisioning bar in `api-auth-design.md`), `status` (active/revoked), `created_at`, `revoked_at`. Rotation: single active secret per client is sufficient at this scale (unlike the signing key, this isn't live-traffic-critical enough to need overlap) — reissue generates a new secret and immediately invalidates the old one; no dual-secret rotation window needed.
27:**Public-key distribution for the verifier (enforcement site, your call was open, ruled here): JWKS served by the issuer Deployment, reachable only in-cluster via its own `ClusterIP` Service — no Ingress route, never publicly reachable.** Not a mounted public-key file: JWKS survives key rotation without redeploying the verifying Deployment's config, since the verifier fetches by `kid` and only needs to know the issuer Service's in-cluster DNS name (`<issuer-service>.<namespace>.svc.cluster.local`), not track individual key files. In-cluster-only because this token scheme's only consumers are `api-service` and `idp-connector`, both already inside the cluster network; there's no reason to add a new publicly-reachable route on a shared production cluster (`threat-model.md` Assumption 7) for a key set that only internal services ever need.
29:**Path and URL (ruled 2026-09-13, per PR #30/LT-51 — fixed now so LT-51 implements to the doc, not the other way around):** `/.well-known/jwks.json`, the OIDC-discovery convention, served only when `APP_MODE=issuer`. Live at `AUTH_JWKS_URL=http://api-service-issuer.loginid-takehome.svc.cluster.local/.well-known/jwks.json`, already wired by Theo.
31:**Cache/refresh guidance:** the issuer may set a normal `Cache-Control: public, max-age=<refresh interval>` on the response as good HTTP practice, but it's advisory only — **the verifier's own staleness policy is authoritative, not the issuer's cache headers.** That policy is already built (PR #30, Tomasz's re-check confirmed it closed): max staleness = 3× the normal refresh TTL, fail closed (`ErrJWKSStale`, distinct `AuditJWKSUnavailable` event) past that bound rather than serving indefinitely-stale keys; an unknown `kid` triggers one out-of-band refetch, rate-limited **per-`kid`** (not one global gate — a global gate lets an unauthenticated caller with a garbage `kid` exhaust the shared refetch slot for free, since `kid` lookup runs before signature verification; keying per-`kid` closes that without reopening the endpoint-hammering concern the rate limit exists to prevent).
50:- **Key retrieval:** middleware verifies with the **public** key only (JWKS or a fetched public key — see `handoff-04-secrets.md` row #3). The private signing key never touches the verifying `api-service` Deployment; it lives with the token-issuing function, which is a mode of the same `api-service` image but runs as its **own Deployment** (`APP_MODE=issuer`, its own ServiceAccount), not the same Deployment doing both (corrected in `handoff-04-secrets.md` Assumption 2 and row #2, F13 — RBAC on a Secret's `get` verb doesn't stop a volume already mounted into a shared Deployment's containers, so the separation has to be a second Deployment, not RBAC alone). This is a second `APP_MODE` value for you to wire alongside your existing config surface.
103:- **Password/client-secret hashing** — Argon2id, decided in `threat-model.md` Asset 1; not this hand-off's concern beyond noting it exists.

}

15:**Client authentication:** HTTP Basic (`client_id`:`client_secret` in the `Authorization` header) — not client credentials in the body. Keeps the secret out of any place that logs request bodies more casually than it logs headers, and is RFC 6749 §2.3.1's preferred client-authentication method.
17:**Request:** `grant_type=client_credentials`, form-encoded (`application/x-www-form-urlencoded`, per RFC 6749 §4.4 — not JSON; this is the one endpoint in this API that follows the OAuth2 spec's own wire format rather than this project's usual JSON convention, because it's the one endpoint implementing a named OAuth2 grant). Optional `scope` parameter (space-delimited) to request a subset of the client's granted scopes; if omitted, issue the client's full granted scope set.
21:**Response, errors (RFC 6749 §5.2, never distinguishing *why* in body or status):** `invalid_client` (401, `WWW-Authenticate: Basic`) for any client-authentication failure — unknown `client_id` and wrong `client_secret` get the **identical** response, same user-enumeration discipline already required elsewhere in this document; `invalid_scope` (400) if the requested scope isn't a subset of the client's granted scopes; `unsupported_grant_type` (400) for anything but `client_credentials`. Token-endpoint brute-force protection (rate limit + backoff per `client_id`/IP, already specified above) applies here, at this exact endpoint.
33:**Ruling on LT-40's URL review token (Warren, via the PM's provisional yes — objecting to the literal framing, not the goal):** review tooling must **never** mint a token by signing directly with the deployed private key — that would hand review/QA tooling the same access this design has spent real effort restricting to the issuer process alone (F13, the whole point of the Deployment split), for a purely operational convenience. The correct equivalent: provision a **dedicated, narrowly-scoped review/QA client credential** (its own row in the client store above, its own `client_id`, scoped to the minimum needed for the review — `profile:read:own` unless the review specifically needs to exercise `profile:search`, in which case it goes through `profile:search`'s own provisioning bar like any other caller) and have the review process call the **real** `/auth/token` endpoint with it. This costs nothing extra to set up, never touches key material outside the issuer process, and is a better test besides — it exercises the actual issuance path instead of bypassing it. If "out-of-band" meant this all along (a scripted call to the real endpoint, not raw signing), then there's no disagreement and this section just makes the mechanism explicit for whoever provisions the review credential.
44:- **Token-endpoint brute-force protection**, separate from the resource-API rate limits below: failed-grant rate limiting and progressive backoff per `client_id` and per source IP on the token-issuing endpoint itself, plus alerting on a sustained run of failed grants against one `client_id`. This protects the endpoint where a caller presents `client_id`/`client_secret`, which none of the resource-API limits below cover.

## Summary

Implements `handoff-03-auth.md` v3/v4's verifier side and wires LT-39's already-built handlers into `cmd/api-service`'s real router, per `refinement/LT-40.md`. This is the story that turns LT-32's issuer split, LT-39's handlers, and LT-34's health endpoint into an actual authenticated, reachable public endpoint.

## What's new

- **`internal/api/jwks.go`** — a minimal RFC 7517 JWKS client: parses RSA public keys, caches the fetched key set with a TTL matching the token TTL's upper bound (per v4's guidance). A stale-but-present cache survives a transient fetch failure rather than hard-failing every request. Supports a `kid` rotation overlap window by construction (caches the whole published key set, not just the newest key).
- **`internal/api/jwtmiddleware.go`** — the verifier, using `golang-jwt/jwt/v5`:
  - Algorithm pinned to RS256 via `jwt.WithValidMethods` on every parse, never left to the library default. Tested against both RFC 8725 §3.1 attacks named in the spec: a bare `alg:none` token, and an HS256 token forged using the RSA public key's DER bytes as the HMAC secret — both rejected before signature verification is attempted.
  - Public-key-only verification, structurally: nothing in `internal/api` or the verifying binary's path ever references signing-key material.
  - `kid`-based key selection with a real rotation-overlap test (two tokens, two `kid`s, one `KeySource` configured with both, both verify).
  - `iss`/`aud`/`exp`/`sub` checked explicitly; `scope` claim disambiguation: a token naming zero or more than one recognized scope is rejected outright rather than silently picking one (matches this project's standing rule against invented authorization ambiguity — `AuthContext` carries exactly one `Scope` by LT-39's own design).
  - Verification failure returns 401 via the existing `writeUnauthorized` — the actual integration seam with LT-39, not new response-shape design.
  - `NewDeadlineMiddleware` applies a concrete `deadlineBudget

  "content": "# LT-51 refinement — real `/auth/token` grant logic\n\n**Product Owner:** Naomi Voss (01). **Research team:** Imogen Hale, Desmond Okafor, Tobias Lindqvist. **Engineering:** Renata Cole (03). **Source:** `03-engineering-delivery/backlog.md` S7a (LT-51); `02-ai-security-architecture/handoff-03-auth.md` v6 (final on JWKS path/cache guidance; v3/v4/v5 content otherwise unchanged).\n\n**Who did the work:** Refined by Naomi Voss (PO); claims check Desmond Okafor; objection Tobias Lindqvist; engineering counterpart Renata Cole.\n\n## Why this one, now\n\nPR #30 (LT-40) has already built the verifier side and the `GrantLimiter` component this story wires to — the only thing standing between the current deployment and a genuinely issued, end-to-end token is this story's actual grant logic. Once it lands, LT-34/LT-39/LT-40/LT-51 all get their joint live-URL review with a real token, per team-lead's ruling.\n\n## What's already built, and what this story actually adds\n\n**Do not rebuild these — wire to them:**\n- `internal/api.GrantLimiter` (PR #30) — the failed-grant rate-limiting/backoff interface, keyed independently by `client_id` and source IP, with alerting on a sustained run against one `client_id`. This story constructs a real implementation instance (or reuses `InProcessGrantLimiter`) and calls `Allow`/`RecordFailure`/`RecordSuccess` around the actual grant attempt — it does not design a new backoff scheme.\n- The JWKS endpoint (`internal/api/jwks.go` serves the client side; the issuer side serving `/.well-known/jwks.json` is this story's job, but the *shape* — RFC 7517, `kid`-keyed — is already established by what the verifier expects).\n- `internal/api.AuthContext`/`WithAuthContext` (LT-39) and the JWT verification middleware (LT-40) — this story's only integration point with them is producing tokens whose claims those already-built and already-tested pieces correctly parse; it doesn't touch either.\n\n**What's genuinely new:** the `POST /auth/token` handler itself — client authentication, the client store, JWT minting, and serving JWKS at the now-fixed path.\n\n## Acceptance criteria (from `backlog.md` S7a, current per `handoff-03-auth.md` v6)\n\n- [ ] `POST /auth/token` implements RFC 6749 §4.4: `grant_type=client_credentials`, form-encoded (`application/x-www-form-urlencoded`), **not JSON** — the one endpoint in this API that follows OAuth2's own wire format rather than this project's usual JSON convention, because it's the one endpoint implementing a named OAuth2 grant. An optional `scope` parameter (space-delimited) requests a subset of the client's granted scopes; omitted means issue the full granted set.\n- [ ] Client authentication is **HTTP Basic** (`client_id`:`client_secret` in the `Authorization` header), **not** credentials in the body — keeps the secret out of anywhere that logs request bodies more casually than headers, per RFC 6749 §2.3.1's preferred method.\n- [ ] Errors follow RFC 6749 §5.2, **never distinguishing why in body or status**: `invalid_client` (401, `WWW-Authenticate: Basic`) for **any** client-authentication failure — an unknown `client_id` and a wrong secret for a known `client_id` return byte-identical responses. `invalid_scope` (400) if the requested scope isn't a subset of the client's granted scopes. `unsupported_grant_type` (400) for anything but `client_credentials`. Enforcement site: a test comparing the unknown-client and wrong-secret response bodies for equality, not just \"both 401.\"\n- [ ] Client store lives in the issuer's own datastore (per F8, not 05's schema): `client_id`, `name` (accountability — no shared credentials across a team), `client_secret_hash` (**Argon2id, same floor as `threat-model.md` Asset 1** — identical hashing discipline to password storage), `granted_scopes` (provisioned subset of `profile:read:own`/`profile:read:any`/`profile:search`/`connector:identity-lookup`), `status` (active/revoked), `created_at`, `revoked_at`. Rotation: single active secret per client (reissue generates a new one and immediately invalidates the old — no dual-secret overlap window, unlike the signing key).\n- [ ] The token-endpoint's own brute-force protection wires to the **already-built** `GrantLimiter` (PR #30) — `Allow` checked before attempting client authentication, `RecordFailure`/`RecordSuccess` called after, keyed by both `client_id` and source IP. Enforcement site: an integration test confirming a sustained run of failed grants against one `client_id` eventually blocks further attempts and fires the alert exactly once per threshold-crossing (not once per subsequent failure) — this is `GrantLimiter`'s own tested behavior, so this test only needs to confirm the wiring, not re-test the limiter's internals.\n- [ ] Issued JWT claims (`iss`, `aud`, `scope`, `exp`, `sub`) and the algorithm/`kid` header match exactly what LT-40's verifier middleware expects — enforcement site: an integration test that mints a token here and verifies it through the **actual** middleware from PR #30, not two independently-trusted unit tests that never touch each other.\n- [ ] **JWKS served at the now-fixed path `/.well-known/jwks.json`** (the OIDC-discovery convention, ruled 2026-09-13 specifically so this story implements to the doc rather than the doc following already-shipped code), issuer-mode only (`APP_MODE=issuer`), reachable only in-cluster via the issuer's own `ClusterIP` `Service` — **no public `Ingress` route**, live at `AUTH_JWKS_URL=http://api-service-issuer.loginid-takehome.svc.cluster.local/.well-known/jwks.json` (already wired by Theo on the client/consuming side). Enforcement site: the route exists at that exact path and is absent from the public `Ingress`'s rules.\n- [ ] The JWKS response may set `Cache-Control: public, max-age=<refresh interval>` as good HTTP practice, but this is **advisory only** — the verifier's own staleness policy (already built, PR #30: max staleness = 3× the refresh TTL, fail closed past that bound, per-`kid` rate-limited refetch on an unknown `kid`) is authoritative, not this endpoint's cache headers. This story does not need to coordinate cache-header values with the verifier's staleness logic; they're independent by design.\n- [ ] **A dedicated, narrowly-scoped QA client credential is seeded in the client store, out-of-band** (same discipline as LT-32's signing-key `Secret` — never through the CI-applied manifest set), **for the PO's joint live-URL review of LT-34/LT-39/LT-40/LT-51.** Per Warren's explicit ruling (via the PM): review tooling must never mint a token by signing directly with the deployed private key — that would hand review tooling the same access F13's whole Deployment split exists to restrict to the issuer process alone. The correct mechanism is this: a real client credential, provisioned like any other caller, calling the real endpoint. Scoped to the minimum needed for the review — `profile:read:own` by default; add `profile:search` only if the review specifically needs to exercise search, going through that scope's own provisioning bar like any other caller, not a blanket grant. Enforcement site: the credential's row in the client store, its `granted_scopes` listed explicitly in the hand-off to the PO (not \"whatever's convenient\"), and confirmation it was created out-of-band.\n\n## Non-goals\n\n- No change to `GrantLimiter`, the JWT verification middleware, or `internal/api`'s existing handlers — all already built (PR #30/LT-39/LT-40); this story only calls into them correctly.\n- No refresh-token support, no denylist/revocation beyond `status=revoked` at the client-store level — matches `api-auth-design.md`'s standing TTL-only-revocation design, not re-litigated here.\n- No UI/API for self-service client provisioning — clients are provisioned directly against the datastore for this take-home's scale.\n- No change to the resource-API's own rate limits or touch counter (LT-39) — this story's `GrantLimiter` wiring is a distinct, separate control, per the interface's own doc comment.\n\n## PO review script\n\n1. Confirm `POST /auth/token` accepts form-encoded `grant_type=client_credentials` and rejects JSON bodies (or at minimum, doesn't require JSON) — read the handler's content-type handling directly.\n2. Confirm HTTP Basic client auth — a client presenting credentials in the request body alone (no `Authorization` header) is rejected.\n3. Confirm the identical-body test for unknown-client vs. wrong-secret exists and passes.\n4. Confirm `client_secret_hash` is Argon2id — read the hashing call, don't infer from a comment.\n5. Confirm the `GrantLimiter` wiring test exists (sustained failures against one `client_id` eventually block, alert fires once per threshold-crossing).\n6. Confirm the mint-then-verify-through-the-real-middleware integration test exists and passes.\n7. Confirm `/.well-known/jwks.json` is live in-cluster and absent from the public `Ingress`.\n8. Confirm the QA client credential exists, was seeded out-of-band, and its `granted_scopes` are stated explicitly (not assumed).\n9. **The joint live-URL review, once this and LT-40 are both deployed:** obtain a real token via `POST /auth/token` using the seeded QA credential, then hit `/profiles/search` and `/profiles/{id}` at the live URL — confirming a masked response, 401/403/429 exactly as LT-39's tests predict, and (per LT-52) a real result set from the actual Postgres instance. This is the review LT-34/LT-39/LT-40/LT-51 have all been building toward; all four are accepted together in this one pass.\n\n## Research team review\n\n**Desmond Okafor — claims check:** [pending]\n\n**Tobias Lindqvist — objection:** [pending]\n\n**Naomi Voss — ruling:** [pending]\n"
