DNS-as-hard-blocker treatment confirmed as the correct conservative reading of §4, not an overstatement. One real error found: the LT-47 auto-deploy criterion attributed \"Theo's explicit agreement\" to `deploy-path.md`, which contained no such record — that agreement came to me directly in chat, not from the cited source. Fixed by rewording to cite only what the source actually supports, and Theo has since recorded the agreement durably in `deploy-path.md` §5a, so the doc now cites that directly.\n\n**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.\n\n**Naomi Voss — ruling:** All fixes applied — the DNS blocker now has a named owner (Amber/Bluehost, via the PM), the auto-deploy citation is corrected and durably recorded, and a teardown-procedure criterion is added. This refinement is accepted and ready to hand off. The teardown gap is the most consequential thing this review round caught across every LT-3x/4x refinement so far — it's the first time the research team's job wasn't tightening a criterion but naming an entire missing dimension of the story."

54	**Tobias Lindqvist — objection:** The build-info freshness criterion and PO script step 3 didn't actually match — the fallback for "no prior observation" (present-and-non-empty) would fire on every first review, meaning the one check meant to distinguish "deployed" from "code exists" would never actually run in practice. Counter-proposal accepted: the PR must include a mandatory second, trivial follow-up commit before merge, and the PO checks the build-info value before and after that commit — not a conditional check that reduces to existence-only on the common path.

Per the PR description, the health handler falls back to `\"unknown\"` specifically when the `-ldflags -X` injection isn't wired through at build time — which is exactly what's happened: the Docker build (04's Dockerfile, LT-45) isn't passing the commit SHA into the `go build` invocation the way the PR's local-build instructions do. The mechanism that would let this criterion be checked at all — build-info actually varying between deploys — isn't present in the deployed artifact. This isn't a cosmetic miss; it's the one thing this story exists to prove (that the pipeline delivers a genuinely fresh, identifiable build), silently not proven.\n\n**Verdict: LT-34 FAILS acceptance.** Not accepting with a footnote — a story whose entire point is \"prove the deploy is real and traceable to a commit\" cannot close while the one field that proves that is a placeholder. Per team-lead's read (independently reached the same way before I ran the script), this becomes a small, scoped follow-up PR: wire the commit SHA through the Docker build (`docker build --build-arg`/`ARG`/`ENV` → `go build -ldflags`), owned by whoever touches the Dockerfile — Theo (LT-45) most likely, since the gap is in the image build step, not the Go code itself; Renata's `-ldflags` invocation was already correct locally. LT-34 stays open until a re-deploy shows a real SHA and the mandatory second-commit freshness check (already satisfied in the PR's own two commits) can be re-run against two actually-distinguishable deployed values."

## S12 — Split the token issuer into its own Deployment with isolated signing-key custody (LT-32)

**Status: open** (from `../decisions/cross-track-consistency.md` F13).

**Description:** The pass caught a real contradiction: `handoff-04-secrets.md` said the JWT signing private key "never touches `api-service`" while also defining the issuer as "a mode of `api-service`," and 04's manifest resolved that by mounting the signing key into every replica of a single `api-service` Deployment — RBAC on a Secret's `get` verb does nothing to stop a volume already mounted into a running container. Fixed at the design level in `handoff-04-secrets.md` Assumption 2 and row 2: the issuer runs as a second Deployment of the same `api-service` image, selected by an environment variable (`APP_MODE=issuer` vs. default), with its own ServiceAccount that alone mounts the signing-key Secret. This story is the implementation and manifest work that design change requires — it did not exist as a story before the pass.

**Acceptance criteria:**
- [ ] `api-service` supports an `APP_MODE` environment variable selecting issuer vs. verifying behavior from one binary/image.
- [ ] Two Kubernetes Deployments exist, each with its own ServiceAccount; only the issuer Deployment's pod spec mounts the JWT signing-key Secret — enforcement site: the manifest's volume mounts plus RBAC Role scoping `get`/`list` to the issuer's ServiceAccount.
- [ ] The verifying Deployment's pod spec contains no reference to the signing-key Secret at all (not just RBAC-denied — physically absent from its mounts).
- [ ] `containerization-design.md`'s mount at the lines the pass named is removed and replaced with the two-Deployment shape.

**Depends on:** `handoff-04-secrets.md` v2 (this track); 03's `APP_MODE` config surface addition; 04's manifest change.

**Model/effort:** sonnet, high (03 implementation); sonnet, high (04 manifest).

## S13 — Wire `api-service`'s client credential to call the connector, and the vendor-token header pass-through (LT-33)

**Status: open** (from `../decisions/cross-track-consistency.md` F3 and F15).

**Description:** Two related gaps the pass found: (1) nothing said what our own `/auth` returns to its caller or how `/identity` obtains vendor authority, given the assignment's fixed `/identity` body has no credential field (F3) — resolved in `connector-security.md` §1: `/auth` returns the vendor token to the authenticated internal caller, which presents it as a request header (not body field) on the subsequent `/identity` call; the connector itself still never caches it. (2) `api-service` needs its own client credential to authenticate to the connector's now-required inbound auth (`connector-security.md` §5) in the first place, and no inventory row covered it — added as row 10 in `handoff-04-secrets.md` (F15). This story is the implementation work both design fixes require.

**Acceptance criteria:**
- [ ] `api-service` obtains and presents a `connector:identity-lookup`-scoped token (via its own client credential, row 10 of `handoff-04-secrets.md`) when calling `idp-connector`'s `/auth` and `/identity`.
- [ ] The onboarding flow's vendor-auth step receives the vendor `access_token` from our `/auth` response and holds it only for the span between that call and the following `/identity` call — enforcement site: the handler/service layer that mediates the onboarding flow, not the connector itself (which remains stateless per S3).
- [ ] `/identity` accepts the vendor token as a request header, not a body field, and fails closed with a generic error if it is missing or rejected by the vendor.
- [ ] `01-product-industry-research-design/ux-notes.md`'s two-screen flow and this mechanism agree on what the frontend/onboarding-flow layer actually holds between screens (coordinate directly with Naomi if the UX description needs a one-sentence update to match).

**Depends on:** `connector-security.md` (this track); `handoff-04-secrets.md` row 10 (this track); 03's connector-client implementation.

**Model/effort:** sonnet, high.

98	**Description:** The client-facing handlers in `internal/api` implementing the assignment's Q2 (search and retrieve `user_profile`), built against S2's interfaces (fakes stand in for a real backend per `decisions/test-double-strategy.md`, so this doesn't wait on S3/S4). 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).
99	
100	**Acceptance criteria:**
101	- [ ] Implements `handoff-03-auth.md` v3's scope vocabulary and pagination/rate-limit numbers without re-deriving 02's authz-scoping reasoning.
102	- [ ] `authorize()` runs as an explicit call inside each handler after request parsing, before the DAO call — enforcement site: handler code structure, per the go-layout-debate.md-adjacent ruling recorded in this track's reply to 02. `authorize()` checks the `caller_referral`/caller-role data against the token-issuer's own datastore, not against 05's schema — 05 was never assigned that table (`handoff-03-auth.md` v3, F8).
103	- [ ] `profile:search` responses carry masked PII fields by default (e.g. phone as `***-***-1234`, address reduced to `locality`/`region` only); unmasked detail requires a separate, separately-audited follow-up call under `profile:read:own` or `profile:read:any` against the specific record id — enforcement site: the search-response serialization path, distinct from the read-response one (`handoff-03-auth.md` v3, resolves F6).
104	- [ ] Cursor-based pagination only, default page size 20, hard ceiling 50 — enforcement site: the pagination parameter parsing, rejecting any offset-based parameter. **The handler's 20/50 is the authoritative clamp, enforced before the DAO is ever called** — the DAO's own `Limit` bound (1..100, default 50 per `multi-db-strategy.md`) is a second, independent backstop only reachable if the handler clamp is bypassed, not a second policy a caller can rely on (consistency-pass F10: no document previously said which of the two governs).
105	- [ ] A search request with no filter field at all is rejected by this handler before it reaches the DAO — the DAO itself treats an all-nil `ProfileQuery` as legal (`multi-db-strategy.md`), so this handler-layer rejection is the only enforcement site for "no bare unconstrained search" (consistency-pass F10, other half owned by 02 in `handoff-03-auth.md`).
106	- [ ] A `profile:search` query is rejected outright, not truncated, if it would exceed the result cap unconstrained (e.g. a bare wildcard) — enforcement site: this handler's query-validation step, per `handoff-03-auth.md` v3's scope table (consistency-pass F52).
107	- [ ] Unmapped DAO errors never surface `err.Error()` to the client; only the mapped sentinels' safe messages do — enforcement site: the boundary translation function from `decisions/error-semantics.md`. Authn failures (missing/invalid token) return 401; scope failures and `authorize()` policy denials both return 403 with an identical client body, distinguished only in the audit log (`decisions/error-semantics.md`, consistency-pass F7).
108	- [ ] `profile:read:any` requests carry a `reason_code` from the closed enum on every call, logged with the audit record.
109	- [ ] When `api-service` calls `idp-connector` on a caller's behalf, it obtains a `connector:identity-lookup`-scoped token first, using its own `CONNECTOR_CLIENT_ID`/`CONNECTOR_CLIENT_SECRET` credential (`PLANNING.md` config surface) — enforcement site: this handler-side outbound-client code, distinct from S8's idp-connector-side handlers, which only validate that token, not issue or hold this credential.
110	
111	**Depends on:** S2; **02: Auth scheme and authorization hand-off** (`handoff-03-auth.md` v3, accepted).
112	**Model/effort:** sonnet, high.
113	**Type:** Story.
114	**Labels:** `track-03`, `security-graded`, `no-code-yet`.

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`).

}

/Users/warrenthompson/Source/LoginID/LOG.md:63:**Phase 4 opened (Warren: "reach out to the product lead and start building out the backlog").** Warren asked whether the product lead was ready to write stories; answer: yes — 01's plan was Jira-shaped from the start. Decision: Epics now, Stories one turn behind the consistency pass (the derived-data deletion gap will likely create a story in nobody's plan, owned jointly by 02/04/05); 01 first because it closed first and the pass touches it least. Team-lead is the single Jira writer; leads author `<track>/backlog.md` (format fixed in `PLAN.md` Phase 4: title, description citing decision files, acceptance criteria with the hand-off standard first and an enforcement site per guarantee, dependencies, model/effort, type, labels). Five Epics created in project `LT`: LT-1 (01), LT-2 (02), LT-3 (03), LT-4 (04), LT-5 (05). 01 transcribed as LT-6…LT-13 (six done stories/tasks, one housekeeping task, one open placeholder for pass findings). All five leads authored their backlogs within the hour: 02 eleven stories (S1–S10 shown as-run, S11 gated on the code go), 03 ten (DAO split into interface/factory, Postgres+CockroachDB package, SQLite package, conformance suite — each a PR-sized unit; handlers build against fakes so REST need not wait for both backends; the connector is the opus seat), 04 six (deletion-gap placeholder left without criteria for a scope not yet owned), 05 seven (six delivered, one open; descriptive cross-track `Blocks` lines rather than guessed titles — resolved by team-lead once all tracks are in Jira). Transcription of 05 delegated to a scribe subagent under the PM session; 02/03/04 follow the pass report.
/Users/warrenthompson/Source/LoginID/LOG.md:65:**Phase 4 — 01 and 05 in Jira; one dependency error found and corrected.** 01: LT-6…LT-12 Done, LT-13 open (pass findings placeholder), four `Blocks` links. 05: LT-14…LT-19 Done, LT-20 open ("Extend subject-deletion to derived data" — the deletion-gap placeholder), seven links; the Story 3 ⇄ Story 4 loop (the contract had to exist to be cold-read and was not stable until the read closed) recorded as a forward link only. The scribe transcribed 05's Story 3 dependency "Stories 1, 2, 6" literally and flagged it rather than guessing; Priya confirmed it was her error — a stale cross-reference carried from her approved `PLAN.md` (where "S4" was the migration approach) through renumbering — and that the true relationship is the reverse: migrations create the contract's tables, so LT-19 depends on LT-16. Link corrected; `PLAN.md` left as approved with an annotation. **Method finding, recorded for the consistency pass:** a wrong cross-reference survived plan approval, four debates, and three cold reads because every reviewer was reading documents, and no review was scoped to the dependency graph. Priya's sharpening: the three cold reads were each scoped to a single document and the error was only visible across two — *a review scoped to a document can only find errors that are in a document*; relationships between artifacts need either a reviewer explicitly scoped to the graph or a representation that makes the graph first-class, which is what the Jira transcription turned out to be. The Jira step is therefore a check, not only a transcription.
/Users/warrenthompson/Source/LoginID/LOG.md:77:**Third pass — planning declared internally consistent (2026-09-12).** Seams 1/4, 3, 5, 9 all AGREE, no new regression: the caller-holds-token model is stated identically in `connector-security.md` §1/§2/attack-tree row 3, `api-connector-design-rationale.md:40,72`, `ux-notes.md:27`, and `handoff-04-secrets.md` rows 6/7; the issuer is one design across `handoff-03-auth.md:20`, `PLANNING.md`'s `APP_MODE`, and 04's issuer Deployment + Service + reachability paragraph; the DAO preamble is a banner; `multi-db-strategy.md:225` names `api-service` as the identity resolver; the audit-stream row and the deliberately excluded `deletion_log` table are drawn the same way by 05 and 04. Seam 13 found five stale restatements, all cosmetic, none load-bearing (03's layout artifacts, two composite-method summaries, a v2→v3 hand-off citation, one retention-class name) — routed to Renata and Theo; no further pass. **Backlog complete in Jira:** 50 issues `LT-1`…`LT-50` under five Epics — 01 `LT-6`…`LT-13` (all Done), 05 `LT-14`…`LT-19` + `LT-50` (Done), 02 `LT-21`…`LT-33` (S1–S10 Done; S11 post-implementation review, S12 issuer split-Deployment, S13 connector credential wiring open), 03 `LT-34`…`LT-44` (all open, gated on the code go), 04 `LT-45`…`LT-49` + `LT-20` (open, design complete); 55+ `Blocks` links including every cross-track hand-off; two ambiguous references ruled by team-lead (`LT-34` blocks `LT-32`; `LT-42` blocks `LT-47`). Consistency-pass tally across three passes: 52 findings, 4 regressions from fixes, 5 cosmetic restatements — every one traceable to a file:line and an owner, none silently dropped.
/Users/warrenthompson/Source/LoginID/PLANNING.md:9:| Orchestration (root) | Dana Whitfield | **Planning complete; backlog implementation-ready** — 50 issues LT-1…LT-50 under 5 Epics (01 LT-6…13 all Done; 05 LT-14…19 + LT-50 Done; 02 LT-21…33, S1–S10 Done; 03 LT-34…44 open, gated; 04 LT-45…49 + LT-20 open), 57 `Blocks` links incl. every cross-track hand-off; three consistency passes closed; PM has reported readiness to Warren | **Warren's implementation go-ahead** | — | `PLAN.md`, `LOG.md`; Jira project `LT` | 18 / 18 (cap) | 2026-09-12 |
/Users/warrenthompson/Source/LoginID/05-data-ops/backlog.md:9:**One deviation from the stated format, flagged rather than fudged.** The format asks for *Depends on* entries by other tracks' story titles. This track's stories have almost no upstream dependencies — 05 is first-wave and on the critical path — so nearly every cross-track link runs the other way. I have therefore added a **Blocks** line where the relationship is downstream, and I name the counterpart *descriptively* rather than inventing a title from 03's or 04's backlog that I have not read. Team-lead has both sides and can link them accurately; guessing another track's story titles would have produced links that look right and point nowhere.

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."

8:2. Service topology is 03's published boundary (`../PLANNING.md`, Service boundaries): two binaries, `cmd/api-service` (Q1 DAO + Q2 REST API) and `cmd/idp-connector` (Q3), env-var configuration only. Variable names below are 03's; two are marked as pending this track's final scheme. **The token-issuing authorization-server function is a mode of `api-service`, not a third binary** — this take-home's scope doesn't justify a standalone authz server, and 03 has published no third `cmd/` entrypoint. **Corrected by the cross-track consistency pass (F13):** "a mode of the same binary" is not "the same Kubernetes Deployment," and the earlier text here was wrong to imply RBAC alone separates them — a Kubernetes Role restricting `get` on a Secret has no effect on a volume already mounted into a container, so if `api-service`'s one Deployment mounted the signing key, every replica (verification path included) would have it on disk regardless of RBAC. **The fix: the issuer runs as a second Deployment of the same `api-service` image**, selected by an environment variable 03 adds to the config surface (e.g. `APP_MODE=issuer` vs. the default, consistent with the surface's env-var-only, no-flags rule), with **its own ServiceAccount that alone mounts the signing-key Secret** (row #2) — the `api-service` Deployment serving verification/search mounts nothing from row #2. This is a request into 03's Deployment/mode surface, not a unilateral change on my part; flag to me if the mode-selection mechanism needs to differ.
17:| 2 | JWT signing **private** key (RS256/ES256), per `api-auth-design.md` | The issuer Deployment (`api-service` image, `APP_MODE=issuer`) only — **not** the `api-service` Deployment that verifies with the public key; these are two Deployments of one image, not one Deployment doing both (F13 fix) | Runtime-injected as a **file**, never an env var; asymmetric so the verifying Deployment never holds it | Key rotation with a `kid` claim; publish old and new public keys together during overlap; TTL of tokens (5–15 min) bounds the overlap window | `Secret` mounted read-only as a file, **only into the issuer Deployment's pod spec** (not the verifying Deployment's); RBAC restricts `get`/`list` to the issuer's own ServiceAccount | Yes |
61:1. **Authorization-server ownership gap.** Accepted. Assumption 2 now states the authz-issuing function is a mode of `api-service`, scoped by a Role narrower than the token-verification code path in the same binary — not a phantom third deployable.

  "content": "# LT-32 refinement — split the token issuer into its own Deployment with isolated signing-key custody\n\n**Product Owner:** Naomi Voss (01). **Research team:** Imogen Hale, Desmond Okafor, Tobias Lindqvist. **Engineering:** Renata Cole (03, `APP_MODE` binary support), Theo Bergman (04, manifest/Deployment split); design owner Marcus Ilori (02, `handoff-04-secrets.md`/F13). **Source:** `02-ai-security-architecture/backlog.md` S12 (LT-32).\n\n**Who did the work:** Refined by Naomi Voss (PO); claims check Desmond Okafor; objection Tobias Lindqvist; engineering counterparts Renata Cole and Theo Bergman.\n\n## Why this one, not LT-39, and why now\n\nChecked the actual dependency chain rather than assuming: `backlog.md` S7 (auth middleware, LT-40) lists \"04: `APP_MODE` Deployment split\" as a hard dependency — that's this story. S6 (the search/retrieve handlers, LT-39) doesn't list LT-32 or S7 as a formal dependency (it can be built and merged against fakes without either), but a handler that calls `authorize()` on claims nothing has yet populated isn't a **reviewable, working endpoint** — it's code that compiles and can't be correctly exercised end-to-end at the public URL. LT-32 is the actual bottleneck: nothing downstream (S7, and a genuinely working authenticated S6) can be truly deployed and reviewed without it. Confirmed by checking the live manifest directly (`deploy/manifests.yaml` on `main` as of this refinement): no `api-service-issuer` Deployment exists, no JWT signing-key mount — this story hasn't landed in any form yet, it isn't partially done.\n\nPer Jira's own resolved ambiguity (`LOG.md`: \"LT-34 blocks LT-32\"), LT-32 was gated on LT-34 landing — LT-34 is now implemented and deployed (review pending only on the build-SHA fix, unrelated to this story), so LT-32 is unblocked and ready to pull.\n\n## What this story actually is, restated plainly\n\nNot a new binary, not new business logic — a **Deployment-topology fix** closing a real security gap the consistency pass found (F13): `handoff-04-secrets.md` said the signing key \"never touches `api-service`\" while the manifest mounted it into every replica of one `api-service` Deployment. RBAC on a `Secret`'s `get` verb does nothing once the volume is already mounted into a running container — so the only real fix is a second Deployment of the same image, selected by `APP_MODE=issuer` vs. the default, with its own ServiceAccount that alone can mount the key.\n\n## Acceptance outcome (no new public-URL behavior yet, but it's the load-bearing gate before any is trustworthy)\n\nThis story doesn't add a caller-visible endpoint — `/healthz` still looks the same. \"Done\" is verified by manifest inspection and a runtime check that the two Deployments' pods genuinely differ in what they can mount, not by curling something new.\n\n## Acceptance criteria (restated from `backlog.md` S12)\n\n- [ ] `api-service` (the Go binary) supports an `APP_MODE` environment variable selecting issuer vs. default (verifying) behavior from one binary/image — no second `cmd/` entrypoint, per `handoff-04-secrets.md`'s explicit \"not a third binary\" ruling. Enforcement site: `internal/config` reads `APP_MODE`, `internal/app` branches on it at startup.\n- [ ] Two Kubernetes Deployments exist in the manifest (`api-service` and `api-service-issuer`), each with its own ServiceAccount. Enforcement site: `deploy/manifests.yaml`, two distinct `Deployment` objects.\n- [ ] Only `api-service-issuer`'s pod spec mounts the JWT signing-key `Secret` — **physically absent, not just RBAC-denied, from `api-service`'s pod spec.** Enforcement site: manifest inspection of `api-service`'s volumes/volumeMounts list, which must contain no reference to that `Secret` at all — a reviewer checking RBAC alone would miss a mistakenly-shared mount, per F13's own finding that RBAC doesn't prevent this class of leak.\n- [ ] RBAC (`Role`/`RoleBinding`) additionally restricts `get`/`list` on the signing-key `Secret` to `api-service-issuer`'s ServiceAccount specifically — a second, independent layer on top of the physical-absence criterion above, not a substitute for it.\n- [ ] The `api-service` (verifying) Deployment holds only the public key material needed to verify, never the private key, regardless of `APP_MODE`'s runtime value — enforcement site: a startup-time check/test asserting the verifying binary's process has no path to the private key even if `APP_MODE` were misconfigured to `issuer` on that Deployment (defense against a manifest typo, not just a design intent).\n- [ ] `containerization-design.md`'s single-Deployment mount (the line the consistency pass named) is removed from the design doc and replaced with the two-Deployment description, so a future reader of the design doc sees the corrected shape, not the superseded one.\n- [ ] The issuer Deployment's public route (whatever path 02/03 finalize for token issuance — e.g. `/auth/token`) is added to the `Ingress`, routed to `api-service-issuer`, distinct from `api-service`'s existing routes; `idp-connector` remains unrouted, unaffected by this change.\n\n## Non-goals\n\n- No change to the JWT scheme itself (claims, TTL, `kid` rotation mechanics) — that's `api-auth-design.md`'s design and S7's (LT-40) implementation, not this story's.\n- No auth middleware implementation (JWT verification, rate limiting) — that's S7 (LT-40), which depends on this story but is a separate pull.\n- No handler-layer `authorize()` logic — that's S6 (LT-39), also downstream of this and S7.\n- No change to `idp-connector` — it has no issuer/verifier split; this story only touches `api-service`.\n\n## PO review script\n\n1.

19	This story doesn't add a caller-visible endpoint — `/healthz` still looks the same. "Done" is verified by manifest inspection and a runtime check that the two Deployments' pods genuinely differ in what they can mount, not by curling something new.
20	
21	## Acceptance criteria (restated from `backlog.md` S12)
22	
23	- [ ] `api-service` (the Go binary) supports an `APP_MODE` environment variable selecting issuer vs. default (verifying) behavior from one binary/image — no second `cmd/` entrypoint, per `handoff-04-secrets.md`'s explicit "not a third binary" ruling. Enforcement site: `internal/config` reads `APP_MODE`, `internal/app` branches on it at startup.
24	- [ ] Two Kubernetes Deployments exist in the manifest (`api-service` and `api-service-issuer`), each with its own ServiceAccount. Enforcement site: `deploy/manifests.yaml`, two distinct `Deployment` objects.
25	- [ ] Only `api-service-issuer`'s pod spec mounts the JWT signing-key `Secret` — **physically absent, not just RBAC-denied, from `api-service`'s pod spec.** Enforcement site: manifest inspection of `api-service`'s volumes/volumeMounts list, which must contain no reference to that `Secret` at all — a reviewer checking RBAC alone would miss a mistakenly-shared mount, per F13's own finding that RBAC doesn't prevent this class of leak.
26	- [ ] RBAC (`Role`/`RoleBinding`) additionally restricts `get`/`list` on the signing-key `Secret` to `api-service-issuer`'s ServiceAccount specifically — a second, independent layer on top of the physical-absence criterion above, not a substitute for it.
27	- [ ] The `api-service` (verifying) Deployment holds only the public key material needed to verify, never the private key, regardless of `APP_MODE`'s runtime value — enforcement site: a startup-time check/test asserting the verifying binary's process has no path to the private key even if `APP_MODE` were misconfigured to `issuer` on that Deployment (defense against a manifest typo, not just a design intent).
28	- [ ] `containerization-design.md`'s single-Deployment mount (the line the consistency pass named) is removed from the design doc and replaced with the two-Deployment description, so a future reader of the design doc sees the corrected shape, not the superseded one.
29	- [ ] The issuer Deployment's public route (whatever path 02/03 finalize for token issuance — e.g. `/auth/token`) is added to the `Ingress`, routed to `api-service-issuer`, distinct from `api-service`'s existing routes; `idp-connector` remains unrouted, unaffected by this change.

If the signing-key `Secret` is part of what the runner applies, its ServiceAccount can already read the private key regardless of how tightly this story scopes the issuer's own RBAC — a second, unexamined path to the same secret, found by cross-referencing two separately-reviewed documents rather than either one in isolation.

**Steps 1, 2, 4, 5 pass:** deploy job green, endpoint returns 200 with valid TLS, the JSON body shape is exactly `{"status","service","build"}` (matches 02's ruling — no version string, no extra fields), and this track's own code-level checks (thin wrappers, config precedence test) were already verified clean against PR #1 earlier in this doc.

**Step 3 (the mandatory freshness check) fails, and it fails for the reason the criterion exists to catch:** `build` is the literal string `"unknown"`, not a commit SHA. Per the PR description, the health handler falls back to `"unknown"` specifically when the `-ldflags -X` injection isn't wired through at build time — which is exactly what's happened: the Docker build (04's Dockerfile, LT-45) isn't passing the commit SHA into the `go build` invocation the way the PR's local-build instructions do. The mechanism that would let this criterion be checked at all — build-info actually varying between deploys — isn't present in the deployed artifact. This isn't a cosmetic miss; it's the one thing this story exists to prove (that the pipeline delivers a genuinely fresh, identifiable build), silently not proven.

**Verdict: LT-34 FAILS acceptance.** Not accepting with a footnote — a story whose entire point is "prove the deploy is real and traceable to a commit" cannot close while the one field that proves that is a placeholder. Per team-lead's read (independently reached the same way before I ran the script), this becomes a small, scoped follow-up PR: wire the commit SHA through the Docker build (`docker build --build-arg`/`ARG`/`ENV` → `go build -ldflags`), owned by whoever touches the Dockerfile — Theo (LT-45) most likely, since the gap is in the image build step, not the Go code itself; Renata's `-ldflags` invocation was already correct locally. LT-34 stays open until a re-deploy shows a real SHA and the mandatory second-commit freshness check (already satisfied in the PR's own two commits) can be re-run against two actually-distinguishable deployed values.

Every prior step (1, 2, 4, 5) still passes, and step 3 now passes as well: `build` is a real, non-placeholder commit SHA, distinct from the prior deploy's `\"unknown\"` value, which is itself the freshness proof (two different values across two deploys, exactly what the mandatory second-commit check exists to demonstrate — the two-commit requirement from Tobias's earlier objection was already satisfied in the PR, and this fix's own redeploy supplied the third, real-world value to compare against).\n\n**Verdict: LT-34 PASSES acceptance.** All criteria met, verified independently at the live public URL, not accepted on report alone.

30:- [ ] **Added per Tobias's objection:** the JWT signing-key `Secret` is excluded from the CI-applied manifest set that the scoped deploy runner (LT-45/LT-47) manages — either provisioned/rotated out-of-band (e.g. a one-time `kubectl create secret` by whoever holds cluster admin, or a dedicated secrets step outside the general `apply` pass), or, if it must be in the applied manifest set, explicitly excluded from the runner's RBAC `resourceNames` for `Secret` gets. Without this, the runner's necessarily-broad `Secret` access for ordinary application config (granted in `deploy-path.md` §2 so `kubectl apply` can diff against live state) would give the CI runner's ServiceAccount read access to the signing key regardless of how tightly this story scopes the issuer's own RBAC — a second, unexamined path to the same secret that criteria 3–4 above don't check for because they only look at the issuer Deployment's own boundary, not the deploy pipeline's.
48:8. **Added per Tobias's objection:** read the scoped CI deploy runner's `Role`/`RoleBinding` (LT-45/LT-47) and confirm the signing-key `Secret`'s name is either absent from its `resourceNames` list, or the `Secret` is never part of the manifest set that runner applies at all — the same negative-check discipline as step 7, extended to the one ServiceAccount the issuer-boundary criteria don't examine.

# Hand-off 02 → 03: Auth scheme, validation point, and authorization requirements

Status: **v3** — updated after the cross-track consistency pass (`../decisions/cross-track-consistency.md`) resolved six findings owned by this track that touched this hand-off (F3, F5, F6, F8, F10, F-pag, F52); v2's S8-driven fixes are unchanged and folded in below as before. 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`.

## Token scheme

- **Grant type:** OAuth2 client-credentials. Machine-to-machine only; no end-user login flow for question 2's API.
- **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).
- **Claim set (minimum):** `sub` (calling client identity), `scope` (space-delimited, values below), `exp`, `iat`, `aud` (this API, specifically — reject tokens minted for another audience).
- **Literal values, filling the "pending 02's final scheme" placeholder in your Service boundaries config surface:** `AUTH_JWT_ISSUER = "https://auth.loginid-takehome.internal"`, `AUTH_JWT_AUDIENCE = "loginid-api-service"`. Both are configuration, not secrets — safe in a `ConfigMap` or committed default, per `handoff-04-secrets.md` row #3.

}

31:| `profile:read:own` | Retrieve a single record by id the caller already holds a legitimate reference to (e.g., a partner resolving a referred user) | Search/query by name or phone fragment; retrieval of a record outside the caller's referral relationship | `target.id` checked against the `caller_referral` mapping (see "Where `caller_referral` and the caller-role table live," below); out-of-set → reject, logged as a policy denial, distinct from an auth failure |
32:| `profile:read:any` | Retrieve a single record by id, no referral constraint | Search/query by fragment | Requires a `reason_code` from a closed enum (below) on every request, logged with the audit record |
33:| `profile:search` | Query by name/phone fragment across the table | — (this is the broadest scope; there is no broader one) | Result cap enforced; a query that would exceed it unconstrained (e.g., bare wildcard) is rejected outright, not truncated |
35:`reason_code` enum for `profile:read:any` (closed, versioned — adding a value is a documented change, not a runtime config toggle): `support_ticket`, `fraud_review`, `kyc_reverification`, `legal_hold`.
37:**Object-level policy hook implementation shape:** a function `authorize(sub, scope, target) -> allow|deny`, called after scope validation, before the handler executes the query/retrieve. This is a second check, not a replacement for the scope check — a valid `profile:read:own` token can still fail `authorize()` if the target isn't in the caller's referral set. **Confirmed placement (per your reply): an explicit call inside each handler right after parsing the request and before the DAO call, not a second middleware** — correct, since `authorize()` needs the parsed target id, which a pre-routing middleware doesn't have. **Enforcement site for the `profile:search` result cap: the same in-handler call site, checked before the query is built** — a query that would exceed the cap unconstrained is rejected there, not truncated after the DAO returns rows.
41:**Response shape and masking (resolves F6 — 01's product requirement had no mechanism to bind to).** `profile:search` responses carry masked PII fields by default (e.g., a phone shown as `***-***-1234`, an address reduced to `locality`/`region` only) — unmasked, full-field detail is obtained only by a follow-up call under `profile:read:own` or `profile:read:any` against the specific record id returned by the search, which is its own separately-audited call per the audit-log section below. This uses scopes that already exist rather than inventing a fourth "expand" concept: masking is a `profile:search`-response property, not a per-call flag, and "tighter than search" is satisfied structurally because `read:own`/`read:any` are already narrower-provisioned scopes than `search`.
43:**Reject an empty search body before the DAO (resolves F10, first half).** A `profile:search` request with no `name` or `phone` filter at all is rejected by the handler with a 400 before it ever reaches the DAO — the DAO's own "an all-nil query is legal and returns every profile" behavior (`../05-data-ops/multi-db-strategy.md`) is a DAO-layer property this API must not expose directly. This is a shape-based rejection, distinct from and in addition to the count-based result-cap rejection above.
47:- **Opaque cursor at the API boundary** (resolves F-pag — the earlier "cursor-based pagination only, no offset-based paging" was wrong to imply offset itself is the enumeration risk: a keyset cursor permits the same page-by-page walk, just statefully; the actual control is the cumulative counter below, and 05's DAO contract is `Offset int`, not keyset). The API-facing cursor may encode the DAO's offset directly — callers cannot construct or walk one by hand, which is the property the boundary exists to give you, and the DAO's offset is never caller-visible. **Enforcement site: the cursor-encoding/decoding step in the handler layer**, opaque to the caller regardless of what it encodes underneath. Default page size 20, hard ceiling 50 (05's DAO ceiling is 10,000 — this API's ceiling is the tighter, caller-facing one; don't expose the DAO's).
48:- **Per-client-credential rate limits:** 60 req/min for `read:own`/`read:any`; 10 req/min for `profile:search`. **Enforcement site: rate-limiting middleware in `internal/api/`, keyed per client credential (`sub` claim).**
49:- **Cumulative distinct-record-touch counter per caller per rolling 24h window**, tracked independently of per-minute rate — this is the control that actually resists decomposition-style enumeration (not the pagination scheme, per the F-pag correction above). **Applies to `profile:read:any` as well as `profile:search`, unconditionally on whether a `reason_code` is present** — a valid, logged `reason_code` satisfies the per-call `authorize()` policy check but does not exempt the caller from this cumulative cap (S8 review fix: the original wording made this counter a no-op for `read:any`, since that scope requires a `reason_code` on every call by design). **Enforcement site: a counting store (Redis, in-process with periodic flush, whatever fits your stack) incremented once per distinct record id returned, checked before the response is sent** — the mechanism is your call; the requirement is that it exists, applies to both scopes, and alerts on threshold, not just hard-blocks.

  "content": "# LT-39 refinement — S6: REST handlers for search/retrieve user_profile (Q2)\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` S6 (LT-39); `02-ai-security-architecture/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\n\nLT-32 (issuer Deployment split) is refined and handed off, unblocking S7 (auth middleware, LT-40), which this story sits alongside. LT-39 itself formally depends only on S2 (merged) and 02's accepted hand-off — it doesn't block on LT-32/S7 in `backlog.md`'s own dependency graph, and its handlers can be built and merged against fakes right now, per `decisions/test-double-strategy.md`. Refining it now means it's ready the moment S7 lands, rather than sitting as the next bottleneck after that.\n\n## Acceptance outcome\n\nThis is the first story that adds real, caller-visible REST behavior — not just a skeleton. But it depends on S7 (auth middleware) to be *truly* reviewable at the public URL with a real token; until S7 lands, \"done\" for this story specifically means: handlers implemented and tested against fakes, all criteria below satisfied in code and unit tests, with the actual live-URL, real-token exercise deferred to whenever S7 merges (same \"verification pending\" pattern as LT-36/LT-37 waiting on LT-38 — not waived, just sequenced).\n\n## Acceptance criteria (restated from `backlog.md` S6, cross-checked against `handoff-03-auth.md` v3)\n\n- [ ] Implements `handoff-03-auth.md` v3's scope vocabulary (`profile:read:own`, `profile:read:any`, `profile:search`) and pagination/rate-limit numbers without re-deriving 02's authz-scoping reasoning.\n- [ ] `authorize(sub, scope, target)` runs as an explicit call inside each handler after request parsing, before the DAO call — not a second middleware, per v3's confirmed placement (it needs the parsed target id, which pre-routing middleware doesn't have). `authorize()` checks `caller_referral`/caller-role data against the token-issuer's own datastore, **not against 05's schema** — 05 was never assigned that table.\n- [ ] `profile:search` responses carry masked PII fields by default (phone as `***-***-1234`, address reduced to `locality`/`region` only). Unmasked detail requires a separate, separately-audited follow-up call under `profile:read:own` or `profile:read:any` against the specific record id — **this reuses the existing scopes, it does not invent a fourth \"expand\" flag**; masking is a `profile:search`-response property, not a per-call parameter. Enforcement site: the search-response serialization path is a distinct code path from the read-response one, not the same serializer with a masking flag.\n- [ ] **Pagination — clarified per v3's F-pag correction, since `backlog.md`'s original wording could be misread by an implementer:** the API-facing cursor is opaque to the caller — callers cannot construct or walk one by hand — but it may (and in the simplest correct implementation, does) encode the DAO's own `Offset` directly underneath. \"Cursor-based pagination only\" means **the caller-facing contract is opaque-cursor-only, not that the handler is forbidden from using the DAO's `Offset` field internally.** The actual anti-enumeration control is the cumulative distinct-record-touch counter (next bullet), not the cursor mechanism itself. Default page size 20, hard ceiling 50, enforced in the handler before the DAO is ever called — the DAO's own `Limit` bound (1..100, default 50) is a second, independent backstop only reachable if the handler clamp is bypassed, not a second policy a caller can rely on.\n- [ ] A cumulative distinct-record-touch counter per caller per rolling 24h window is enforced, independent of per-minute rate limits, applying to **both** `profile:search` and `profile:read:any` unconditionally — a valid `reason_code` on `read:any` satisfies the per-call `authorize()` check but does **not** exempt the caller from this cumulative cap (v3's explicit fix to an earlier wording that made the counter a no-op for `read:any`). Enforcement site: a counting store incremented once per distinct record id returned, checked before the response is sent, alerting on threshold.\n- [ ] A search request with no filter field at all is rejected by this handler with a 400 before it reaches the DAO — the DAO itself treats an all-nil `ProfileQuery` as legal, so this handler-layer rejection is the only enforcement site for \"no bare unconstrained search.\"\n- [ ] A `profile:search` query rejected for exceeding the result cap unconstrained (e.g. a bare wildcard) is rejected outright, not truncated — enforcement site: the same in-handler call site, checked before the query is built.\n- [ ] Unmapped DAO errors never surface `err.Error()` to the client; only the mapped sentinels' safe messages do — per `decisions/error-semantics.md`'s boundary translation function. Authn failures (missing/invalid token) return 401; scope failures and `authorize()` policy denials both return 403 with an identical client-visible body, distinguished only in the audit log.\n- [ ] `profile:read:any` requests carry a `reason_code` from the closed enum (`support_ticket`, `fraud_review`, `kyc_reverification`, `legal_hold`) on every call, logged with the audit record — adding a fifth value is a documented change to this enum, not a runtime config toggle.\n- [ ] When `api-service` calls `idp-connector` on a caller's behalf, it obtains a `connector:identity-lookup`-scoped token first, using its own `CONNECTOR_CLIENT_ID`/`CONNECTOR_CLIENT_SECRET` credential — distinct from S8's idp-connector-side handlers, which only validate that token, not issue or hold this credential.\n\n## Non-goals\n\n- No auth middleware implementation — that's S7 (LT-40), a separate pull; this story's own tests use fakes for the auth context per `decisions/test-double-strategy.md`.\n- No real backend I/O — built against fakes, per `decisions/test-double-strategy.md`; LT-36/LT-37/LT-38 land separately.\n- No connector-side (`idp-connector`) handler work — that's S8, which only validates the token this story's handler obtains, not the same code.\n- No rate-limit/counter *mechanism* choice (Redis vs. in-process) — that's Renata's implementation call, per v3's own \"the mechanism is your call\" framing.\n\n## PO review script\n\n1. Confirm `authorize()` is called explicitly inside each handler, after parsing, before the DAO call — not registered as middleware. Read the handler code directly.\n2. Confirm the search-response serializer and the read-response serializer are genuinely distinct code paths (grep for two separate serialization functions, not one with a masking conditional).\n3. Confirm the pagination cursor is opaque at the API boundary (no caller-suppliable offset/page-number parameter accepted) — but don't fail the story if the handler internally passes `Offset` to the DAO; that's the correct implementation per the F-pag clarification above.\n4. Confirm the cumulative distinct-record-touch counter's test coverage includes a `profile:read:any` case with a valid `reason_code` still hitting the cap — this is the specific regression v3 fixed, so it needs its own test, not just a `profile:search` test.\n5. Confirm a 401/403 test pair exists asserting identical response bodies for a scope failure vs. an `authorize()` denial, distinguished only in a separate audit-log assertion.\n6. Once S7 lands and this is deployed: a live-URL check with a real client-credentials token, confirming an actual masked search response and an actual 401 on a missing/expired token — deferred, not waived, per the Acceptance outcome above.\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"

{"body":"## Summary\n\nImplements the Go-code half of LT-32 (`refinement/LT-32.md`) — closing consistency-pass finding F13: `handoff-04-secrets.md` said the JWT signing key \"never touches `api-service`\" while the manifest mounted it into every replica of one `api-service` Deployment. RBAC on a `Secret`'s `get` verb does nothing once the volume is already mounted, so the real fix is a second Deployment of the same image, selected by `APP_MODE`, with its own ServiceAccount that alone mounts the key.\n\nThis PR is the `internal/config`/`internal/app` half — the Deployment/manifest/RBAC/Ingress split is Theo Bergman's (04) half, tracked separately; per the PM's merge-gate instructions this can land in the same PR set or paired.\n\n## What changed\n\n**`internal/config`:**\n- `APP_MODE` is now validated, not just defaulted — an unrecognized value is a startup error instead of silently falling through to `\"verifier\"`. A typo'd Deployment running in the wrong mode is exactly the invisible-misconfiguration class this story exists to close.\n- Added `JWTSigningKeyPath` (env `JWT_SIGNING_KEY_FILE`), read only when `AppMode == \"issuer\"`, per `handoff-04-secrets.md` row #2 (\"runtime-injected as a file, never an env var\"). In issuer mode, `Load()` requires the file to exist and be readable, checked at startup.\n\n  This is the enforcement site for the refinement doc's defense-in-depth criterion: *\"the `api-service` (verifying) Deployment holds only the public key material needed to verify, never the private key, regardless of `APP_MODE`'s runtime value ... even if `APP_MODE` were misconfigured to issuer on that Deployment.\"* The verifying Deployment's pod spec never mounts the signing-key `Secret` or sets `JWT_SIGNING_KEY_FILE` (04's side); this change means that even if `APP_MODE` were flipped to `\"issuer\"` there by mistake, `Load()` fails startup instead of running as a half-issuer with no actual key.\n\n**`internal/app`:**\n- `NewRouter(service, mode)` — the router is the startup-time branch point the refinement doc names (\"internal/app branches on it at startup\"): in `ModeIssuer`, a placeholder `/auth/token` route is registered (501, reserved for S7/LT-40 — no cryptography, no reference to `JWTSigningKeyPath`); in `ModeVerifier` that route does not exist (404), not just unauthorized. Mirrors the manifest split's physical-absence principle at the HTTP-routing layer.\n- `cmd/api-service/main.go` passes `cfg.AppMode` through. `cmd/idp-connector/main.go` passes `app.ModeVerifier` explicitly — it has no issuer/verifier split (non-goal in `refinement/LT-32.md`), and that value adds no route beyond `/healthz`.\n\n## Tests added\n\n- `internal/config`: unknown `APP_MODE` rejected; issuer mode rejects a missing signing-key file; issuer mode rejects an unreadable/nonexistent signing-key file; issuer mode succeeds with a real file and reports its path on `Config`; verifier mode ignores the env var entirely even if set.\n- `internal/app`: is

# narrower than 04-infra-devops/containerization-design.md's full design:
# no migration Job, no DB_DSN secret — those wire up config the current
# code doesn't use yet (config.Load() never errors on an unset
# DB_DSN/DB_DSN_FILE). This file grows to match once 03 lands DAO wiring.
#
# No Namespace object here, deliberately: the scoped loginid-takehome-deployer
# ServiceAccount's RBAC (deploy/rbac.yaml) is namespace-scoped to
# loginid-takehome and correctly cannot get/create/patch a cluster-scoped
# Namespace object — that's the isolation working as designed, not a gap.
# The namespace itself is created once, out of band, by whoever runs the
# initial cluster bootstrap (deploy/rbac.yaml also creates
# loginid-takehome-runners for the same reason).
#
# No Secret object here either, and none ever will be for the JWT signing
# key specifically: deploy/rbac.yaml's Role grants nothing on `secrets` at
# all, so an attempt to apply one here would fail Forbidden, the same way
# Namespace did. The signing-key Secret is created out-of-band — see
# deploy/issuer-secret-bootstrap.yaml — per Tobias's (01) accepted
# objection on LT-32's refinement: the CI-applied manifest set must never
# be the thing that can read or write that key.

Theo correctly did not build this and explained why: mounting a `Secret` as a volume is authorized by the kubelet against the node when the pod spec is admitted — it does not require the pod's own ServiceAccount to hold `get`/`list` RBAC on that `Secret` via the API server. A `Role` granting `api-service-issuer` read access to a `Secret` it already receives by volume mount would authorize nothing the mount actually uses; it would be RBAC that looks like a control without functioning as one. **The actual control is elsewhere:** `loginid-takehome-deployer` (the CI runner's Role) has zero grants on `secrets` at all, so it can never read or write the signing-key `Secret` regardless of what's in the manifest set — that's the real, functioning isolation layer, and it's already in place (`deploy/rbac.yaml`).

Exactly what having a standing research team is for.\n\n## PO acceptance review — run against the live deployed cluster\n\n**Reviewer:** Naomi Voss (PO). **Date:** 2026-09-13. **Deploy:** `main@c371ebf`, GitHub Actions run `https://github.com/wtvamp/loginid-takehome/actions/runs/34737708651`.\n\n**Method:** read the actual merged manifests (`deploy/manifests.yaml`, `deploy/rbac.yaml`, `deploy/issuer-secret-bootstrap.yaml`) directly from `origin/main` myself, cross-checked against Theo's live `kubectl` evidence (full pod-spec dumps, not single-field greps) rather than accepting either source alone.\n\n- **Criteria 1–3 (APP_MODE support, two Deployments/ServiceAccounts, physical absence of the signing-key mount from `api-service`):** confirmed independently from the manifest source and from Theo's live dump — `api-service`'s pod spec has zero volumes, zero volumeMounts, no Secret-referencing env var; `api-service-issuer`'s mounts the Secret read-only exactly as designed. **Pass.**\n- **Criterion 4 (RBAC scoping):** corrected during this review (see the crossed-out note above) — the criterion as originally written asked for an inert control; the real, functioning isolation is the CI runner's Secrets-RBAC exclusion, already in place. **Pass, on the corrected understanding.**\n- **Criteria 5–7 (verifying Deployment holds no private key regardless of `APP_MODE` misconfiguration; design doc updated; issuer route added to Ingress):** confirmed — `internal/config`'s `APP_MODE` validation rejects an unrecognized value at startup rather than silently defaulting, and issuer-mode `Load()` requires a real, readable signing-key file (PR #18); `/auth/token` is live and routes to `api-service-issuer`, returning the designed 501 placeholder; `idp-connector` unaffected. **Pass.**\n- **Criterion 8 (signing-key Secret provisioned out-of-band):** confirmed — created by Theo directly via `kubectl create secret`, documented in `deploy/issuer-secret-bootstrap.yaml`, never touched by the CI-applied manifest set. **Pass.**\n- **Residual-risk finding (Deployment-write RBAC can mount any Secret, found during this review, not in the original criteria):** confirmed real by Theo (no admission controller on this cluster); accepted as a residual risk given the take-home's scale, with a named mitigation (CI grep check) in progress. **Accepted risk, not a blocking defect** — recorded above, mitigation PR to follow before this story is fully closed.\n\n**Bonus finding, unrelated to this story's own criteria but caught while gathering evidence for it:** `api-service-issuer`'s second replica was stuck `FailedCreate` — the namespace `ResourceQuota`'s `limits.cpu` was sized before this story added a second 2-replica Deployment. Fix already up as PR #22, not blocking this verdict since it's a resource-sizing bug, not a security or correctness defect in what LT-32 itself set out to build.\n\n**Verdict: LT-32 PASSES acceptance**, conditional on PR #22 (ResourceQuota fix) merging so both `api-service-issuer` replicas actually come up, and the CI-check mitigation PR landing before this story is marked fully Done in `backlog.md` — both are follow-up PRs already in flight, not open questions about the story's own design."

Theo confirmed no admission controller exists on this cluster to prevent it structurally. Accepted as a residual risk given the take-home's scale (standing up Kyverno/Gatekeeper would be disproportionate); mitigation is a cheap CI grep check, PR in progress.

52:**Accepted risk, with mitigation:** standing up a cluster-wide admission controller for a take-home's namespace would be disproportionate scope. Mitigation instead: a CI check (PR-check workflow) that greps `deploy/manifests.yaml` for the signing-key `Secret`'s name and fails the build if it appears anywhere outside the `api-service-issuer` Deployment's own YAML block. This does not stop a determined actor with merge rights (who could also remove the check), but it converts an accidental or careless PR from "silently mounts the key" to "CI catches it before merge." Flagged to Marcus (02) for visibility given the security-graded label; mitigation PR in progress with Theo.

Built and tested against fakes (`decisions/test-double-strategy.md`) — no auth middleware (S7/LT-40) and no real backend I/O in this story, both explicit non-goals.\n\n**Not wired into `cmd/api-service`'s live router yet.** Doing so before S7's JWT verification middleware exists would expose unauthenticated PII — exactly what the auth design exists to prevent. Wiring happens once S7 lands (refinement doc's \"Acceptance outcome\": handlers implemented and tested against fakes now, live-URL verification with a real token deferred, not waived).\n\n## Package layout (`internal/api`)\n\n- **`auth.go`** — `Scope`, `AuthContext` (+ context helpers), `ReasonCode` (closed enum), and `Authorizer` — the object-level policy hook (`authorize(sub, scope, target)`), called explicitly inside each handler after request parsing and before the DAO call, not as a second middleware, per v3's confirmed placement. Real implementation is a follow-up story against the token-issuer's own datastore (`caller_referral` lives there, per v3's F8 resolution) — this is the seam.\n- **`ratelimit.go` / `touchcounter.go`** — `RateLimiter` (60 req/min read:own/read:any, 10 req/min search) and `TouchCounter` (cumulative distinct-record-touch cap per caller per rolling 24h window, applying to `profile:read:any` unconditionally regardless of `reason_code` — the exact regression v3 fixed). Both interfaces with in-process implementations; a shared store (Redis) is a drop-in replacement for a multi-instance deployment. Crossing the touch cap hard-denies (429) subsequent requests for the remainder of the window — the request that crosses it still completes, only the next one is denied.\n- **`cursor.go`** — opaque pagination cursor at the API boundary, encoding the DAO's `Offset` underneath per v3's F-pag correction. Default page size 20, hard ceiling 50, enforced in the handler before the DAO is ever called.\n- **`masking.go`** — `profile:search`'s masked response (`SearchResultProfile`) is a distinct type with a distinct serialization function from the full read-response shape (`ProfileResponse`) — not the same serializer with a masking flag.\n- **`errors.go`** — boundary translation per `decisions/error-semantics.md`: only the DAO's seven sentinels' safe messages (plus `context.DeadlineExceeded` → 504) ever reach a client; everything else is a generic 500 with no wrapped detail. A scope failure and an `authorize()` denial return an identical client-visible body (F7) — enforced by both call sites routing through one function.\n- **`handlers.go`** — `NewSearchHandler` and `NewGetProfileHandler`. Search rejects an all-nil filter body with 400 before the DAO, and rejects a `page_size` over the cap outright rather than truncating. `GetProfile` handles both `profile:read:own` and `p

**Tobias Lindqvist — objection:** The cumulative counter's "alerts on threshold, not just hard-blocks" wording doesn't clearly require denying the caller's subsequent requests once the threshold is crossed — as written, a caller over-cap could keep issuing served calls indefinitely with only an alert firing, recreating the "attribution stands in for volume control" gap his own S4 objection closed at the product-requirements level. Checked against the source: the ambiguity is genuinely in `handoff-03-auth.md` v3 itself, not a transcription error in this refinement — so this is 02's mechanism decision, not mine to invent. Routed to Marcus with Tobias's argument; the criterion is marked PENDING in the doc with his exact proposed wording ready to drop in if 02 confirms hard-deny.

**Naomi Voss — ruling:** This refinement is accepted and ready to hand off in full. Marcus has since ruled on the pending item: crossing the cumulative counter's threshold hard-denies (429) subsequent calls, alerting in addition to, not instead of, the denial — exactly the outcome Tobias argued for. Updated above with his exact ruling and a matching PO-script step (4a). Every criterion is now resolved; nothing remains pending.

Every criterion is now resolved; nothing remains pending.\n\n## PO acceptance review — PR #26\n\n**Reviewer:** Naomi Voss (PO). **Date:** 2026-09-13. **PR:** `https://github.com/wtvamp/loginid-takehome/pull/26`.\n\nPulled the PR and ran `go build ./... && go test ./internal/api/... -v` myself — all 25 tests pass, not taking the PR description's claim on faith. Confirmed by name and content, not just by count:\n\n- `TestSearchHandler_TouchCapExceeded_429NotServed` and `TestGetProfileHandler_ReadAny_ValidReasonCodeStillHitsTouchCap` — both regression tests from this refinement's PO-script items 4/4a exist and pass, asserting an actual 429 HTTP response and that the underlying handler (`Search`/`Get`) is never called once denied — not merely that a counter value is observed to exceed threshold.\n- `TestGetProfileHandler_ScopeFailureAndAuthorizeDenial_IdenticalBody` — F7's identical-body requirement, present and passing.\n- `TestCursor_OpaqueAtAPIBoundary` — confirms the cursor is opaque at the boundary while the DAO's `Offset` is used internally, matching the F-pag clarification exactly.\n- `TestSearchHandler_ResponseIsMasked`, `TestSearchHandler_EmptyBody_400`, `TestSearchHandler_PageSizeAboveCap_RejectedNotTruncated`, `TestSearchHandler_DAOError_NeverLeaksRawMessage` — all present and passing, covering the masking, empty-search-rejection, cap-rejection, and error-sanitization criteria.\n- `authorize()` is called explicitly inside `handlers.go`, not registered as middleware — confirmed by reading the handler code directly, not inferred from the PR description.\n\n**Correctly not wired into the live router yet** — the PR's own reasoning (exposing unauthenticated PII before S7's middleware exists would defeat the purpose of this story's own authz work) matches this refinement's \"Acceptance outcome\" section exactly.\n\n**Verdict: LT-39 PASSES on every criterion checkable without S7.** Live-URL verification with a real token remains deferred, not waived, until S7 (LT-40) lands and this gets wired in — per this doc's own stated acceptance outcome, not a new condition invented at review time."
