Under\n concurrent requests from the same sub, every one of them could read\n Allowed()==true before any recorded a touch, letting N concurrent\n requests each add a full page's worth of distinct touches — overshoot\n by a multiple of the page size, not the one-request overshoot the\n design accepts. Fixed: TouchCounter is now Reserve(ctx, sub,\n maxNewTouches)/Settle(ctx, sub, recordIDs, reserved) — Reserve\n atomically checks capacity AND books a worst-case-sized placeholder\n under one lock, so a second concurrent request sees the first's\n reservation and is denied before either request's DAO call returns.\n Every handler exit past a successful Reserve calls Settle exactly once\n (with the actual record ids on success, or nil to release the full\n reservation on a denial/error). Proven with a real-goroutine\n concurrency test (TestInProcessTouchCounter_ConcurrentReservesNeverExceedCap,\n passes under -race) firing 20 concurrent requests at 50 each against a\n cap of 100 and asserting total granted never exceeds it.\n- Unbounded map growth in both InProcessRateLimiter and\n InProcessTouchCounter (a sub that stops calling stays in the map\n forever) — added opportunistic sweeping in TouchCounter, gated so it\n costs nothing per-request (at most once per window duration).\n\nOren Castellan (error semantics / nullability):\n- TouchCounter's cap was being applied to profile:read:own too, despite\n the package's own doc comment saying it applies to search/read:any\n only, and no test covering read:own against the cap in either\n direction. handoff-03-auth.md v3 names search and read:any explicitly\n and never read:own — read:own is bounded by the caller_referral\n relationship, not an open id space, so it isn't the enumeration\n surface this control exists for. Fixed: the Reserve/Settle calls are\n now scoped to ac.Scope == ScopeReadAny in NewGetProfileHandler; added\n TestGetProfileHandler_ReadOwn_DoesNotHitTouchCap to lock the exemption\n in.\n- writeDAOError was being called from RateLimiter/TouchCounter/Authorizer\n error paths despite being named and documented as the DAO-sentinel\n translator — functionally safe (none of those errors satisfy\n errors.Is(err, dao.ErrXxx), so they fell through to the same generic\n 500 anyway) but invited a future bug where a DAO-specific case added to\n that switch silently reshapes a non-DAO failure too. Split into a\n second function, writeInternalError, for all non-DAO collaborator\n errors.\n- reason_code is validated but had no consumer beyond that validation —\n added a comment explaining it's threaded into every audit event on the\n request (see below) and that a real policy-decision consumer, if one\n is ever needed, is a follow-up story's job.\n\nIngrid Solano (02's independent review, PM ruling — unmet acceptance\ncriterion, not a follow-up):\n- No audit-log emission existed anywhere, despite handoff-03-auth.md v3\n requiring reason_code and the scope/authorize() distinction to be\n \"logged with the audit record\" and \"distinct signals for detection.\"\n Added internal/api/audit.go: AuditLogger interface (parallel to\n Authorizer/RateLimiter/TouchCounter, with StdoutAuditLogger as the\n in-story-scope real sink — 04's retention/RBAC-separated log pipeline\n is separate infrastructure work this interface doesn't depend on) and\n AuditEvent carrying exactly the fields v3's audit-log section names\n (sub, scope, kind, record ids, reason_code, timestamp). Both handlers\n now call it at every decision point (authn failure, scope failure,\n rate limited, cap exceeded, authorize() denial, request failed,\n success) with a distinct AuditEventKind per point.\n TestGetProfileHandler_ScopeFailureAndAuthorizeDenial_IdenticalBody now\n also asserts the two paths emit AuditScopeFailure vs. AuditPolicyDenial\n respectively — the client-visible body stays identical (F7); the audit\n log is the only place the distinction is allowed to exist.\n- An unrecognized field in a search request body (in particular an\n \"offset\" key) was silently ignored rather than rejected — exactly the\n bypass the opaque-cursor-only pagination contract (v3's F-pag) exists\n to close. Fixed with json.Decoder.DisallowUnknownFields(); added\n TestSearchHandler_RejectsUnknownField.\n\nAlso aligned NewSearchHandler's and NewGetProfileHandler's check ordering\n(shape validation before either limiter, both limiters before\nauthorize()) — they previously disagreed for no stated reason (Oren\nCastellan).\n\nVerified: go build/vet clean, go test ./internal/api/... -race green (33\ntests, up from 25), gofmt clean, full repo suite (go test ./...)\nunaffected.\n\nStory: LT-39\nWork-By: Renata Cole (lead), reviewed by Oren Castellan, Nolan Reyes\n(03), and Ingrid Solano (02, independent review, routed by Marcus Ilori)\n\nCo-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>\nClaude-Session: https://claude.ai/code/session_011Cuba4JUvrsQCrTdUj4yzk\nEOF\n)\""

}22:2. Deadline propagation is a budget-allocation decision, stated explicitly in S3's middleware design: the HTTP-boundary timeout must be sized to cover realistic p99 DAO latency *plus* any upstream work (e.g., no DAO call should ever be handed a near-zero remaining deadline as a matter of routine operation). This gets a concrete number attached when S3's middleware design is written, not left as "some deadline." 27:Ruled. Carries into S2 (Repository implementation contract: transaction scoping, detach points) and S3 (middleware deadline budget). 37:**F17 — stale references to a token cache dropped.** Item 3 originally also named "any token-persistence write" as a detach point, left over from before 02's S3 ruling settled on no-cache-by-default for the connector's vendor tokens (`decisions/connector-token-lifecycle-redblue.md`). There is no token-persistence write in the current design, so the phrase is removed (done above) rather than left to describe a mechanism that no longer exists.

Implements the object-level `authorize(sub, scope, target)` call as an explicit in-handler step, not a second middleware, per the ruling in `handoff-03-auth.md` v3 (my own answer, confirmed by 02). 118:## S7. Auth middleware (JWT validation) (LT-40) 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. 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. 138:## S7a. Token issuance: real `/auth/token` grant logic (LT-51) 140:**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. 146:- **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. 147:- **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. 153:- [ ] 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. 155:- [ ] **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. 156:- [ ] 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. 158:**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). 165:## S8. Connector: /auth + /identity (Q3) (LT-41) 173:- [ ] 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. 183:## S9.

}18 19 All three accepted; no decline. 20 21 1. Any `Repository` method that writes to more than one table (e.g., a profile+credential save) runs inside a single `Tx`. Context cancellation during that transaction triggers `Tx.Rollback`, never a partial commit — this is a stated requirement on the `Repository` implementation contract, not left to each backend's discretion. 22 2. Deadline propagation is a budget-allocation decision, stated explicitly in S3's middleware design: the HTTP-boundary timeout must be sized to cover realistic p99 DAO latency *plus* any upstream work (e.g., no DAO call should ever be handed a near-zero remaining deadline as a matter of routine operation). This gets a concrete number attached when S3's middleware design is written, not left as "some deadline." 23 3. Credential writes are named explicitly as the path that needs a detach point for durability, distinct from profile reads and other cancel-safe paths, which propagate the inbound context unmodified. This distinction is documented at the point each such method is implemented, not left implicit. 24 25 ## Status 26 27 Ruled. Carries into S2 (Repository implementation contract: transaction scoping, detach points) and S3 (middleware deadline budget). 28 29 ## Resolved against 05's contract (2026-09-12) 30 31 Oren's first-pass review of 05's DAO contract flagged a real tension: this ruling's item 1 requires any multi-table write to run in a single `Tx`, but the contract as first landed had no method spanning both `user_profile` and `user_credential`, and explicitly barred 03 from composing a cross-call transaction — leaving registration's profile+credential creation with no atomic path at all. 05 resolved it by adding `CreateProfileWithCredential(ctx, p, c)` on the `Repository` composite (05's §3b) — the one cross-table operation in the contract, DAO-generated IDs for both rows, single transaction, `c.UserID` ignored on input and set from the just-created profile. This ruling's item 1 now has exactly one caller-visible method satisfying it, rather than being a requirement with no concrete instance.

}1 # LT-40 refinement — S7: auth middleware (JWT validation)
2
3 **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` v4 (v3 unchanged except where v4 states otherwise).
4
5 **Who did the work:** Refined by Naomi Voss (PO); claims check Desmond Okafor; objection Tobias Lindqvist; engineering counterpart Renata Cole.
6
7 ## Why this one, now, and at priority
8
9 This 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.
10
11 ## Correction to `backlog.md`'s own story text, found before drafting
12
13 **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.
14
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.
16
17 ## Acceptance outcome
18
19 "Done" for this story is a working, tested JWT-verification middleware wired into `cmd/api-service`'s router, with LT-39's handlers reachable through it at the live URL. **Corrected per team-lead, per Marcus's actual design:** nothing ever signs with the deployed private key outside the issuer process — there is no "out-of-band token minted directly against the signing key" path, review or otherwise; the private key's only caller is `/auth/token`'s own real grant logic (LT-51). **LT-40 merges and deploys to In Test on its own** (middleware + wiring, verified by unit tests here), **but its live-URL review happens together with LT-51's**, using a real token obtained from `/auth/token` via a dedicated, narrowly-scoped QA client credential seeded in the client store (LT-51's own criteria). LT-40 and LT-51 go Done together, in one PO pass, with a genuinely issued token — not LT-40 alone on a workaround token.
20
21 ## Acceptance criteria (restated from `backlog.md` S7, corrected per the finding above)
22
23 - [ ] 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.
24 - [ ] 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.
25 - [ ] 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).
26 - [ ] **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.
27 - [ ] `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.
28 - [ ] 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.**
29 - [ ] 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.
30 - [ ] 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."
31 - [ ] 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.
32
33 ## Non-goals
34
35 - **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.
36 - No change to `internal/api`'s handler logic, masking, or error translation — that's LT-39 (PR #26, code-review-passed, not yet merged to main).
37 - 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.
38 - 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.
39
40 ## Open question — resolved
41
42 **Original question:** `backlog.md` had no 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, and nothing downstream picked up the real logic. Tobias's objection sharpened this from "a gap this refinement can flag and work around" to "a missing story, not a pending one" — unlike LT-36/37's wait on LT-38, or LT-32's wait on LT-34, this had no ticket and no scheduled end, and treating an out-of-band token as this story's own review method risked quietly weakening "done = deployed and reviewable at a public URL" into "done = reviewable by an engineer with cluster access," without anyone deciding that on purpose.
43
44 **Resolution (team-lead):** confirmed as a real gap and a new story, not scope creep and not "out of scope forever." **LT-51** (Epic LT-3, security-graded, linked LT-40 → blocks → LT-51) — OAuth2 client-credentials grant at `/auth/token`, per Marcus's `handoff-03-auth.md` v4 addendum (now landed): HTTP Basic client auth, form-encoded `client_credentials` grant per RFC 6749 §4.4, §5.1/§5.2 token/error responses with an identical `invalid_client` for unknown-client vs. wrong-secret (no oracle distinguishing the two), client store in the issuer's own datastore with Argon2id-hashed secrets, a `jti` claim recommended for audit correlation only (not a revocation mechanism — TTL-only revocation stands per `api-auth-design.md`), and the public key distributed via a JWKS endpoint served by the issuer's in-cluster `ClusterIP` `Service` — no public `Ingress` route for it, since only the verifying middleware inside the cluster needs it. 03-owned code, 02-supplied spec. Refined right after this story.
45
46 **Corrected ruling on the review token, replacing the earlier "out-of-band" framing:** there is no path where the private key signs anything outside the issuer process, not even for review. LT-40's live-URL review therefore happens *together with* LT-51's, using a real token obtained from a real `/auth/token` call, authenticated with a dedicated, narrowly-scoped QA client credential seeded specifically for this purpose (LT-51's own criteria, below) — not a workaround token and not a separate acceptance event.
47
48 ## PO review script
49
50 1. Confirm the algorithm-allowlist and `kid`-rotation unit tests exist and pass — read the test names and assertions directly, not just "tests pass."
51 2. 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.
52 3. 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.
53 4. 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.
54 5. **Run jointly with LT-51's review, once both are deployed:** obtain a real token from `/auth/token` using the seeded QA client credential (LT-51's criteria), then 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/LT-40 have all been waiting on; LT-40 and LT-51 go Done together in this one pass, not separately.
55
56 ## Research team review
57
58 **Desmond Okafor — claims check:** Re-verified directly against PR #26's actual diff (not the doc's own word) that `Deps`/`RateLimiter`/`TouchCounter` are handler-level, not middleware — confirmed, narrowing was accurate. Two minor status fixes: "that's LT-39, already merged" was wrong (PR #26 is still open) — fixed; the doc header cited only v3 when the body already treats v4 as landed — fixed to cite v4. 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.
59
60 **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.
61
62 **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.

Two follow-on\nfindings, both fixed here:\n\nOren: every cleanup Settle call on an error-exit path reused ctx — the\nsame context whose expiry or cancellation is often exactly why the\npreceding call (Authorize, the DAO call) just failed. Reserve/Settle's\nown doc comment already says a real backend (Redis) could then fail the\nrelease itself under a dying context, silently leaking reserved budget\nuntil the window's own sweep. Same principle decisions/\ncontext-propagation.md already applies to DAO credential writes,\none layer up.\n\nNolan: every Settle call was manually placed at each handler return\npath rather than derived from one release point — safe today because\nevery existing path was traced by hand, but fragile by construction: the\nnext early return added to either handler without an accompanying\nSettle call silently burns that caller's cumulative-cap budget for the\nrest of the 24h window, and a panic between Reserve and any Settle call\ndoes the same with no recovery.\n\nFixed both together with one change: touchcounter.go gains\ntouchReservation, a small guard returned by reserveTouches() alongside\nReserve's bool result. Handler code now does\n`defer tr.release(ctx)` immediately after a successful reserve, and\n`tr.settle(ctx, ids)` on the success path — settle marks the reservation\nfinalized so the deferred release becomes a no-op; every other exit\n(error, denial, or an outright panic) is covered by the defer with no\nper-branch Settle call required. release() itself calls Settle through\ncontext.WithoutCancel(ctx), addressing Oren's finding directly. Both\nhandlers' manual Settle-at-every-branch code is gone, replaced by one\nReserve+defer pair each.\n\nTestSearchHandler_PanicStillReleasesTouchReservation proves the guarantee\nNolan's finding was about: it panics from inside Authorize, recovers only\nat the test boundary (not inside the handler — nothing in the handler\nneeds a recover for this to work), and asserts the reservation was still\nreleased. TestSearchHandler_DeniedRequestReleasesTouchReservation\n(previous commit) continues to pass unchanged against the new\nimplementation.\n\nVerified: go build/vet clean, go test ./internal/api/... -race green (34\ntests), gofmt clean, full repo suite unaffected.\n\nStory: LT-39\nWork-By: Renata Cole (lead), reviewed by Oren Castellan and Nolan Reyes\n\nCo-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>\nClaude-Session: https://claude.ai/code/session_011Cuba4JUvrsQCrTdUj4yzk\nEOF\n)\""

Traced every Reserve/Settle exit point in both handlers — all present and correct at that commit.\n\nOne new finding: every cleanup `Settle` call on an error path reused the request's own `ctx` — the same context whose expiry/cancellation is often exactly why the preceding call failed. Harmless today (the in-process implementation ignores its `ctx` argument entirely), latent for whoever backs this with Redis (a canceled context could make the release itself fail, silently leaking reserved budget until the window's sweep). Fixed in aacb633 via `context.WithoutCancel`.\n\nWork-By: Oren Castellan (QA)\n\n---\n\n**Nolan Reyes — re-review, round 2 (commit f93b19d)**\n\nVerified the concurrency race is genuinely closed, not just moved — traced `Reserve`'s lock structure directly: the capacity check and the reservation booking happen inside one critical section (`c.mu`), so there is no window between \"check passes\" and \"reservation becomes visible\" to a second concurrent caller. `TestInProcessTouchCounter_ConcurrentReservesNeverExceedCap` fires 20 real goroutines under `-race` at 10x the cap's overshoot potential and asserts it never exceeds it — the right test for the failure mode, not a design-intent assertion.\n\nOne finding, not a blocker on its own but worth fixing before this pattern gets copied: every `Settle` call was manually placed at each handler return path rather than derived from one release point. Every path existing today is correct (traced line by line), but the next early return added without an accompanying `Settle` call — or an outright panic between `Reserve` and any `Settle` — silently burns that caller's cumulative-cap budget for the rest of the 24h window, with nothing to catch it.\n\nFixed in aacb633: a `touchReservation` guard with `defer tr.release(ctx)` immediately after a successful `Reserve`, and `tr.settle(ctx, ids)` on the success path (marking the reservation finalized so the deferred release becomes a no-op). `TestSearchHandler_PanicStillReleasesTouchReservation` proves the actual guarantee — panics from inside `Authorize`, recovers only at the test boundary, asserts the reservation was still released. This is exactly the shape of guarantee a manual per-branch call can't give.\n\nVerdict: race closed, correctly, and now defended against both the maintenance-fragility and cleanup-context concerns raised in this round.\n\nWork-By: Nolan Reyes (QA)\nEOF\n)\""

Everything from v3 is 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`. 5:## Token issuance (`POST /auth/token`) — v4 addendum 19:**JWT claims issued:** `iss` = `https://auth.loginid-takehome.internal`; `aud` = `loginid-api-service` or `idp-connector-service` depending on which audience the authenticated client is registered for (a client is provisioned for one audience, not both); `sub` = `client_id`; `scope` = the granted-or-requested set, space-delimited; `exp`/`iat` per the 5–15 min TTL already specified; header `kid` identifying the signing key version. **`jti` (recommended, not required):** a random per-token identifier, included solely as an audit-log correlation aid (so a token's issuance and its later use can be joined in logs) — it is never checked against a denylist at verification time, since this design already ruled out stateful revocation in favor of short TTLs; including it costs nothing statefully and is worth the correlation value. 21:**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. Verifier caches the fetched key set in memory with a short TTL (matching token TTL is reasonable) to avoid a JWKS fetch on every single verification. 28:- **Token format:** JWT, signed, asymmetric (RS256 or ES256 — pick one and use it consistently; RS256 is the safer default if your Go JWT library's ES256 support is less mature). 33:- **Verifier must pin the expected algorithm** (whichever of RS256/ES256 you choose) and reject a token whose header claims any other algorithm, including `alg: none` and a downgrade to a symmetric algorithm using the public key as an HMAC secret (RFC 8725 §3.1). Check your JWT library's default behavior — several popular libraries have shipped this vulnerability by not doing this by default. 40:- **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. 41:- **Key rotation:** expect a `kid` claim; publish old and new public keys together during rotation overlap. Token TTL (5–15 min) bounds how long that overlap needs to last.

}147:- **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. 154:- [ ] 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. 158:**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).

"message": "Starting LT-40 (JWT verification middleware). Two things I don't think are mine to decide unilaterally since they're live security policy, not mechanism:\n\n1. Authorizer real implementation is explicitly out of scope for LT-40 (the datastore doesn't exist yet — \"a later story\" per handoff-03-auth.md v3's F8 resolution). But LT-40's acceptance outcome requires the handlers actually reachable at the live URL for the joint LT-40/LT-51 review. I need *something* concrete plugged into internal/api.Deps.Authz for that review to happen. Options I see: (a) a permissive stand-in that allows every request (loudly commented as temporary, reviewed away once the real datastore lands), (b) a stand-in that only allows the seeded QA client's own sub, denying everyone else (safer default, but is that enough to demonstrate read:own's referral-check semantics for the reviewer?), (c) something else you'd prefer. What do you want here for the live review, given nothing signs a token except the real issuer?\n\n2. handoff-03-auth.md gives concrete numbers for the per-minute rate limits (60/10 req/min) but I don't see an actual number for the cumulative distinct-record-touch cap's rolling-24h threshold — just \"the mechanism is your call,\" not the number. What should the cap be? (Tests/refinement docs never named one either, as far as I can tell.)\n\nProceeding with the JWT verification core (RS256 pinning, kid rotation, JWKS fetch/cache, aud/iss checks) in parallel since that part's unambiguous — just flagging these two before I wire the live Deps.",
