200:## S10. README: implemented vs. stubbed, AI workflow, test strategy (LT-43)
201-
202-**Description:** The track's README stating what's implemented vs. stubbed/mocked and why, the AI tool/workflow used to produce this track's code (Claude Code, this org's hiring and orchestration-pattern structure — `PLAN.md`, `decisions/`), and a test-strategy section citing `decisions/test-double-strategy.md`'s same-PR fake-update rule explicitly, per the standing note from team-lead.
203-
204-**Acceptance criteria:**
205-- [ ] A cold reader can tell what runs vs. what's a stub without asking — the same bar as every hand-off in this project.
206-- [ ] Test-strategy section states unit-heavy, integration deliberately stubbed (the assignment doesn't require full end-to-end), and names the same-PR fake-update rule from `decisions/test-double-strategy.md` explicitly.
207-- [ ] AI tooling note names the model/effort tiers actually used per story (from this backlog) and the orchestration patterns run (`decisions/go-layout-debate.md`, `decisions/error-semantics.md`, `decisions/context-propagation.md`, `decisions/test-double-strategy.md`), not just that "Claude Code was used."

209-**Depends on:** S1–S9.

216-## S11. Retention sweep: DeleteExpired / DeleteProfile wiring (LT-44)
217-
218-**Description:** Consistency-pass finding F21 identified that 05's retention policy (`pii-governance.md`) had no reachable DAO method, and no track owned writing the sweep job itself. 05's contract addendum (`multi-db-strategy.md` §3c, post-Oren-review-final) added `DeleteExpired(ctx, class, olderThan, maxRows)` (batched, `SweepResult{RowsExamined, RowsDeleted, OldestSurvivingAt, Drained}`, one transaction per batch) and `DeleteProfile(ctx, id, externalRef)` (reason is asserted internally as `"subject_request"`, not caller-supplied) to the composite — this story is 03 claiming ownership of the code that calls them: the periodic batched sweep invocation (looping per `RetentionClass` until `Drained`, using `pii-governance.md`'s windows and a bounded `maxRows` per call), the subject-deletion request path, and surfacing the health signal to 04.

  "content": "# LT-43 refinement — S10: README (implemented vs. stubbed, AI workflow, test strategy)\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` S10 (LT-43).\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, why it matters more than most\n\nPer team-lead: this is the document LoginID reads first — the submission's front door — and it should be written by someone who watched the process, not generated at the end from a summary of a summary. Depends on S1–S9, all of which are now Done or in their final pass, so this is genuinely ready to write for real, not from a plan.\n\n## What \"implemented vs. stubbed\" actually is, checked directly rather than assumed\n\n**Real, live, deployed:**\n- Full DAO layer against real Postgres (LT-35/36/38 — all Done, verified live against the deployed database and in CI against real Postgres/CockroachDB service containers).\n- REST search/retrieve handlers (LT-39 — Done), auth middleware (LT-40), real token issuance (LT-51 — refined, in progress), all verified live at `https://loginid-takehome.uplifttech.org` with real minted tokens.\n- The connector's own inbound `/auth`/`/identity` contract (LT-41 — Done, verified in-cluster via port-forward with a real vendor stub backing it).\n- CI/CD (LT-47), containerization (LT-45), secrets delivery (LT-46), database provisioning (LT-52) — all Done, deployed, live.\n\n**Deliberately stubbed, and why — this is the section a cold reader needs, stated plainly, not left to infer:**\n- **The third-party vendor (ABC/XYZ) is an in-process `StubVendorClient`**, not a real HTTP integration — `idp-connector` falls back to it when `IDP_ABC_BASE_URL` is unset, logs this explicitly on startup, and this is `backlog.md`'s own stated non-goal for LT-41 (\"no real vendor integration\"). The assignment names the vendor generically; a real integration was never in scope.\n- **The `authorize()` object-level policy hook is a `StopgapAuthorizer`**, not the real caller-referral datastore `handoff-03-auth.md`'s F8 resolution describes — a stated seam, not a hidden gap, per LT-39/LT-40's own non-goals.\n- **CockroachDB and SQLite are exercised in CI only, never deployed live** — only Postgres runs in the actual cluster (LT-52's explicit scope limit). A reader should not expect to find CockroachDB running anywhere.\n- **No `POST /profiles` write endpoint exists or is planned** — Q2 is search/retrieve by the assignment's own text; a write path was ruled out as scope creep (team-lead + Priya's decision, recorded on LT-39). Review/demo data enters via a version-controlled, idempotent SQL file (`deploy/demo-data/001-review-profiles.sql`) applied as a documented runbook step, not through the API.\n- **Rate limiting, the touch counter, and the token-issuer's grant limiter are in-process, single-replica-only** — their own code comments state a shared store (Redis) is needed for a genuine multi-instance deployment; this project runs `api-service`/`api-service-issuer` at 1 replica with `Recreate` rollout strategy specifically so this simplification holds correctly, not silently degrading under a rolling update (a real live-tested bug this project found and fixed, not a hypothetical).\n- **`api-service` calling the connector (LT-33)** is in progress as of this writing — the piece that makes Q2 and Q3 one system, not yet merged.\n\n## Acceptance criteria (restated from `backlog.md` S10)\n\n- [ ] A cold reader can tell what runs vs. what's a stub without asking — same bar as every hand-off in this project. The \"deliberately stubbed\" list above is the actual content this criterion requires; the README section should be at least this specific, not a vaguer restatement.\n- [ ] Test-strategy section states: unit-heavy, integration deliberately stubbed (the assignment doesn't require full end-to-end); the same-PR fake-update rule from `decisions/test-double-strategy.md`, **now also a literal checklist line in `.github/pull_request_template.md`** (LT-42's fix — cite both, since the design doc alone was found insufficient during this project's own review).\n- [ ] AI tooling note names the actual model/effort tier per story, not just \"Claude Code was used\": `sonnet, high` for every implementation story in this track's backlog except the connector (`opus, high` — the one seat above sonnet, per `planning-approach.md`'s connector-token-lifecycle exception, because a subtle bug there directly contradicts this project's own threat model). Names the actual orchestration patterns run and what they produced: `decisions/go-layout-debate.md` (package/binary-split decision), `decisions/error-semantics.md` (rotating devil's-advocate, Oren's objections), `decisions/context-propagation.md` (deadline-budget ruling), `decisions/test-double-strategy.md` (hand-written-fakes ruling, Marisol's mitigation). This project is also an org-orchestration exercise across five tracks with hired sub-teams (`PLAN.md`, `CASTING.md`) — worth one sentence acknowledging that's the broader structure this track's own patterns sit inside, without re-explaining the whole org here (that's `../CLAUDE.md`'s job).\n- [ ] **Added — a real, live-tested finding worth naming, not just the design-time patterns:** this track's own PO review (a Product-track lead running live acceptance checks against the deployed system, not just code review) found and helped fix three real production-shaped bugs during this project — a CI coverage gap that silently skipped two of three backend test suites, a cross-replica rate-limiting bug reproduced by actually crossing the cap live, and a total connector-auth outage from a missing manifest env var. Naming this is itself evidence of the process the AI-workflow note should describe: verification against the live, deployed system, not only against a test suite or a design doc.\n\n## Non-goals\n\n- No re-explanation of the org-wide orchestration structure (leads, hires, `CASTING.md`) — that's the root `CLAUDE.md`'s and `LOG.md`'s job; this README covers track 03's own AI-workflow story specifically.\n- No new code, no new tests — this is a documentation story.\n- No speculative \"future work\" section beyond what's already named as a stated seam elsewhere (`StopgapAuthorizer`, the vendor stub, Redis for multi-instance) — don't invent a roadmap this project hasn't committed to.\n\n## PO review script\n\n1. Read the README's \"implemented vs. stubbed\" section cold, as an evaluator would: can every item in the \"deliberately stubbed\" list above be found stated plainly, with a reason, not just a bare \"TODO\"?\n2. Confirm the test-strategy section cites both `decisions/test-double-strategy.md` and the PR-template checklist line — not just the design doc alone (the exact gap LT-42 found).\n3. Confirm the AI-workflow note names actual model/effort tiers per story (spot-check against `backlog.md`'s own `Model/effort:` lines) and actual orchestration-pattern outcomes (spot-check against the cited `decisions/*.md` files), not generic claims.\n4. Confirm the three live-review findings (CI skip, rate-limit/replica bug, connector-auth outage) are named somewhere in the AI-workflow or test-strategy section, not omitted as inconvenient detail — a submission that only shows the clean end-state, with none of the process that found real bugs, undersells the actual work done.\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"

17	### PR #18 — LT-32, `APP_MODE` issuer/verifier split (Go side)
18	**Reviewer:** Helena Marsh. **Verdict: approve, no blocking findings.**
19	Verified by test, not inspection alone, that verifier mode never touches the signing-key file (`TestLoad_VerifierModeIgnoresSigningKeyFile`, including the adversarial case of the env var being set anyway). Confirmed `kid`/rotation correctly deferred to a later story (this PR was scaffolding only — no signing code existed yet). Two non-blocking forward notes: (1) real signing code (later, LT-51) must stay gated behind `appMode == "issuer"` at point of use, not hoisted to package `init()`; (2) `Config` (now carrying a secret-file path) should never be logged wholesale.
20	**Disposition:** both notes carried forward; (1) verified structurally satisfied by PR #34/#39 (issuance code lives in the token handler, not package-level); (2) not independently re-verified since — worth a targeted check if `Config` dumping is ever added anywhere.

83:**Blocking defect, confirmed from the connector's own logs, not inferred:** every request — the genuinely valid token included, indistinguishable from the no-token and wrong-audience cases — returned 401. Logs: `"JWKS fetch failed (host=, class=network_error): api: fetching JWKS from : Get \"\": unsupported protocol scheme \"\""`. Root cause confirmed in the manifest: `idp-connector`'s `Deployment` in `deploy/manifests.yaml` sets only `HTTP_ADDR` — `AUTH_JWKS_URL` is never set, unlike `api-service.yaml`, which correctly sets it to the issuer's in-cluster JWKS endpoint. The connector's inbound auth is completely non-functional as deployed — not a partial gap, a total one, for every caller. Same class of defect as the earlier `AUTH_JWT_ISSUER`/`AUTH_JWT_AUDIENCE` gap (config surface supported by code, never wired into this specific manifest).

That one really is a total idp-connector (Q3) auth outage — I verified it directly against the connector, not api-service.\n\nSo LT-43's third bullet is about this second incident, not the one you checked.

A CI coverage gap where `pr-check` silently skipped every Postgres and CockroachDB conformance test (only SQLite genuinely ran), reading as a green build with two of three backends unproven.\n  2. A cross-replica rate-limiting bug in `api-service`'s own resource-API rate limiter, reproduced by actually crossing the 10 req/min cap live against 2 running replicas.\n  3. `api-service`'s own Q2 token issuer/verifier wiring shipped with `AUTH_JWT_ISSUER`/`AUTH_JWT_AUDIENCE` unset in its manifest — minted tokens carried no `iss` and were checked against an empty `aud`, silently \"verifying\" for the wrong reason.\n  4. A **separate, later** total outage in `idp-connector`'s (Q3's) own inbound auth — its Deployment manifest never set `AUTH_JWKS_URL` at all, so every request, including a genuinely valid token, failed identically with a JWKS-fetch error.

Everything else in the \"deliberately stubbed\" list confirmed against code inspected in earlier passes. **One real omission found:** the retention sweep (LT-44/S11) is missing from the list entirely — `DeleteExpired`/`DeleteProfile` exist only on the DAO interface and in test fakes, no `cmd/` caller, no `CronJob` manifest anywhere; a real, tracked, backlogged story with zero operational wiring, the same class of gap as the other stubbed items. Added with his exact wording.\n\n**Tobias Lindqvist — objection:** The original draft's third \"live finding\" bullet mislabeled a real `api-service` (Q2) issuer/verifier config bug as a \"connector-auth outage,\" which points a cold reader at the wrong subsystem (`idp-connector`/Q3, never involved in that specific incident). Checked against my own LT-41.md record and confirmed: there's a second, genuinely separate incident that *is* a real `idp-connector` outage (missing `AUTH_JWKS_URL` in its own manifest, verified directly via port-forward against the connector itself) — both are real, distinct, and now named individually and correctly attributed rather than conflated into one vaguely-worded bullet. Confirmed and approved once the split was applied.\n\n**Naomi Voss — ruling:** All fixes applied — LT-44 added to the stubbed list, the two distinct auth incidents split and correctly attributed to their actual subsystems. This refinement is accepted and ready to hand off. The precision Tobias insisted on here matters for exactly the reason he named: this is the one document evaluators read first, and getting \"which subsystem broke\" right is itself evidence of the same rigor this whole review chain has been running."

216:## S11. Retention sweep: DeleteExpired / DeleteProfile wiring (LT-44)
217-
218-**Description:** Consistency-pass finding F21 identified that 05's retention policy (`pii-governance.md`) had no reachable DAO method, and no track owned writing the sweep job itself. 05's contract addendum (`multi-db-strategy.md` §3c, post-Oren-review-final) added `DeleteExpired(ctx, class, olderThan, maxRows)` (batched, `SweepResult{RowsExamined, RowsDeleted, OldestSurvivingAt, Drained}`, one transaction per batch) and `DeleteProfile(ctx, id, externalRef)` (reason is asserted internally as `"subject_request"`, not caller-supplied) to the composite — this story is 03 claiming ownership of the code that calls them: the periodic batched sweep invocation (looping per `RetentionClass` until `Drained`, using `pii-governance.md`'s windows and a bounded `maxRows` per call), the subject-deletion request path, and surfacing the health signal to 04.
219-
220-**Acceptance criteria:**
221-- [ ] Implements 05's addendum without re-deriving the transaction-boundary or batching reasoning.
222-- [ ] Loops `DeleteExpired` per `RetentionClass` until `Drained` is true, each using the class's own clock as specified (`updated_at` for `direct`/`idp_cache`, `created_at` for orphans) — enforcement site: the sweep invocation loop, one class at a time, no shared/mixed predicate.
223-- [ ] `DeleteExpired` is never called with a request-scoped context — the sweep's own job/scheduler context governs it, never an inbound HTTP request's, so a sweep is never silently cancelled because an unrelated request ended — enforcement site: the sweep invocation code's context construction, plus a test asserting an already-cancelled context returns before deleting anything.
224-- [ ] `SweepResult.OldestSurvivingAt` is published to 04's observability **only from a `Drained == true` result** — a non-drained (mid-sweep) batch reports progress, not health, and must not fire the alert; 04 alerts only from the drained result (flagged to Theo directly, since this is the interaction Priya caught that neither original finding raised).
225-- [ ] `DeleteProfile` is the only path used for a subject-deletion request; ordinary application deletes still go through `Profiles().Delete` (no log row), and this distinction is preserved rather than collapsed for convenience.
226-- [ ] The `Drained`/`OldestSurvivingAt` coupling gets a one-line doc comment at the field declaration in the eventual Go code (Oren's note) — so a future implementer reading `OldestSurvivingAt` in isolation mid-sweep doesn't treat a stale value as current.
227-
228-**Depends on:** S2; **05: retention sweep contract addendum** (`multi-db-strategy.md` §3c, pending Oren's first-pass review — same process as the original contract); **04: Story 5 — Observability** (`04-infra-devops/backlog.md`, owns where the sweep job runs, and the `rows-examined`/`rows-deleted`/`oldest-surviving-row-age` metrics sink and alert rule this story's `OldestSurvivingAt` feeds). Named as Story 5, not Story 6 — Story 6 is log-sink retention for the audit trail, a different concern; Story 5 is the one that actually specifies the retention-sweep alerting this story depends on.
229-**Model/effort:** sonnet, high.
230-**Type:** Story.
231-**Labels:** `track-03`, `from-consistency-pass`, `security-graded`, `no-code-yet`.

38:**The audit-stream row is enforced by 04, not by this schema.** Its enforcement site is 04's log-sink retention policy (`../04-infra-devops/observability.md`), which is what the consistency pass ruled and what `LT-20` cites. Nothing in the DAO reaches it: the sweep methods in `multi-db-strategy.md` §3c operate on `RetentionClass` values, all three of which are `user_profile` classes.
43:2. **No method sweeps it.** `DeleteExpired` takes a `RetentionClass`, and there is no class for it. If a window is ruled, implementing it is a **contract change** — either a fourth class or a separate method — not a configuration value someone can set. Flagging that now so the cost is visible at the time of the ruling rather than discovered after it.
60:| **Bulk retention sweep** (scheduled) | `source` = the class, plus that class's clock older than that class's window; orphan class additionally requires no referencing credential. **One class per pass — never a mixed-class sweep**, because a single predicate spanning two clocks is how the wrong window gets applied to the wrong rows | Many rows | Cascade delete, implicit and unmentioned in the predicate — the sweep selects profiles and destroys credentials as a side effect. Stated because it is invisible at the point of use | **Hard delete** | One row in a separate `deletion_log`: profile UUID, `source`, `deleted_at`, reason `retention_sweep`, job run id. **No name, phone or address** | Schedule it; run it per class; emit the metrics below | **Nothing errors.** No exception, no alert, no symptom — rows accumulate and the policy is fiction nobody can see is fiction |

26	## Retention windows (S5)
27	
28	**Every number below is a proposed POC default pending a product/legal ruling.** One asymmetry belongs stated plainly rather than buried: GDPR Art. 5(1)(e) storage limitation is a **principle** — data kept "no longer than is necessary" — demanding a window someone justifies. It is not a number anyone can look up. So every basis below is either an engineering rationale or the honest word *unknown*. There is no third kind, and a citation implying a regulation supplies a specific duration would be a false statement in a client-facing document.
29	
30	| Data class | Clock column | Proposed window | Basis | Disposal | What cascades | Ratifier | Status |
31	|---|---|---|---|---|---|---|---|
32	| `user_profile`, `source='direct'` | `updated_at` | **24 months** since last update | *unknown — needs product/legal ruling.* Engineering basis only: long enough that a dormant account surviving a slow re-engagement cycle is not destroyed, short enough to be a defensible answer to "why do you still hold this." No regulation supplies this number | Hard delete | Cascade FK destroys all `user_credential` rows — the account stops existing | unknown — no named legal owner on this POC | Proposed |
33	| `user_profile`, `source='idp_cache'` | `updated_at` | **30 days** since last hydration | Engineering: **a cache is not a record.** Re-hydration costs one `/identity` call, so deleting too early costs a vendor round-trip. Vendor data also goes stale — a 14-month-old cached address is a correctness problem before it is a privacy one. We are downstream custodian of another party's collected PII with no independent relationship to the subject, which argues for the shortest window that still functions | Hard delete | Cascade FK; a cached profile should not normally have credentials — if it does, it is no longer merely a cache and product must say which clock wins | unknown | Proposed |
34	| `user_profile`, `source='idp_cache'`, **no referencing `user_credential`** (orphaned cache) | **`created_at`**, deliberately not `updated_at` | **7 days** since creation | Engineering: lookup residue, not an account — someone called `/identity`, we cached the answer, nothing was ever built on it. **The clock is `created_at` because `updated_at` is touched by the read and re-hydration path: an orphan re-read on any schedule would keep resetting its own expiry and never die.** Closing that loop is the entire reason this row exists | Hard delete | Nothing — by definition it has no children | unknown | Proposed |
35	| **Audit-log stream** (the emitted log entries evidencing deletions, as read by 04's sink) | the entry's own timestamp | **Proposed, pending ruling — see basis** | **unknown — needs a legal ruling.** The audit stream evidences that a deletion happened, which is useful for exactly as long as someone may ask. That period is a question about limitation windows and regulator expectations, not an engineering one, and no engineering rationale substitutes for it | Expiry at the sink | Nothing | unknown — needs product/legal ruling | **Proposed** |
36	| `user_credential` | — | **No independent window** | Wholly governed by its profile's window via the cascade FK. A credential cannot outlive its profile; a credential row with no profile cannot exist. A second clock could only ever disagree with the first, with no resolution rule | n/a | n/a | **Ruled** |
37	
38	**The audit-stream row is enforced by 04, not by this schema.** Its enforcement site is 04's log-sink retention policy (`../04-infra-devops/observability.md`), which is what the consistency pass ruled and what `LT-20` cites.

}

33:## Retention-sweep observability (05's S5 requirement, final)
35:Per `../05-data-ops/pii-governance.md`: the retention sweep must emit, per data class per run, three metrics — rows examined, rows deleted, and **the age of the oldest surviving row in that class**. An alert fires when that age exceeds the class's stated retention window plus one sweep interval. This is the one metric in this document tied to a specific reasoning worth repeating: a sweep job that silently stops running produces no error and no symptom on its own — "rows deleted" can't tell a broken sweep from a legitimately empty one, since both report zero. Oldest-surviving-row age is the one number that keeps climbing when the job is dead and holds steady when it's healthy, which is why it's the alerting signal, not just a nice-to-have metric alongside the other two.
37:Mechanism: the sweep job (whatever invokes it — a CronJob against the lab cluster, per 05's mechanism-agnostic requirement) emits these as Prometheus metrics with a `class` label matching 05's actual retention classes — `source="direct"`, `source="idp_cache"`, and `idp_cache_orphan` for an orphaned `idp_cache` row (`../05-data-ops/pii-governance.md`), never a label carrying the PII itself, same discipline as the RED-metrics rule above. (An earlier draft of this section invented `vendor_token_cache`/`idp_identity_cache` as class names — those don't correspond to anything 05 tracks and described a connector token cache the S3 ruling never adopted; corrected here.) The alert rule is `oldest_surviving_row_age_seconds{class="X"} > (retention_window_seconds + sweep_interval_seconds)`, evaluated per class.
39:**Batched sweeps: only a drained result feeds the metric.** 05's `DeleteExpired` is batched (a bounded `maxRows` per call, `SweepResult.Drained` marking the last batch of a sweep) — `OldestSurvivingAt` is meaningful only on a `Drained == true` result, since mid-sweep the oldest deletable row is still present by construction and would read as stale on every batch but the last. The sweep job emits `oldest_surviving_row_age_seconds` only from drained results, never from an intermediate batch; the alert rule above already only ever sees what's published, so this is a constraint on what the job emits, not an extra filter the alert needs to apply. Getting this wrong means the alert fires on every sweep and gets muted, which is worse than not having it.
49:No SLOs/error-budget policy, no alerting-rule catalog beyond the retention-sweep alert above. A take-home needs the shape of an observability approach and a credible enforcement mechanism for the one hard requirement (never-log); it doesn't need a full SRE runbook.

  "content": "# LT-44 refinement — S11: retention sweep, `DeleteExpired`/`DeleteProfile` wiring\n\n**Product Owner:** Naomi Voss (01). **Research team:** Imogen Hale, Desmond Okafor, Tobias Lindqvist. **Engineering:** Renata Cole (03, sweep-invocation code), Theo Bergman (04, `CronJob` manifest + metrics sink); design inputs: Priya Nandakumar (05, retention windows/clocks/classes), Marcus Ilori (02, seat on subject-deletion audit trail if any).\n\n**Who did the work:** Refined by Naomi Voss (PO); claims check Desmond Okafor; objection Tobias Lindqvist.\n\n## Why this one, now\n\nPer team-lead: without this, the README (LT-43, correctly deferred to write last) would have to list PII retention as stubbed — at a company whose own product framing is PII minimization, that's a real, visible gap in the submission, not a cosmetic one. Desmond's LT-43 finding made the case concretely: `DeleteExpired`/`DeleteProfile` exist and are tested on the DAO composite, but nothing schedules or calls either method — a designed-but-not-operational control. This is roughly a half-day story (a `CronJob` calling a `--sweep` mode of the existing `api-service` image, bounded by the already-built `maxRows`, audited) that turns a stub line into a delivered one.\n\n## What this story actually is\n\nNot new DAO methods — `DeleteExpired`/`DeleteProfile` already exist on the composite (05's `multi-db-strategy.md` §3c) and are already tested (LT-38's conformance suite: `TestConformance_DeleteExpired_*`, `TestConformance_OldestSurvivingAt_*`, `TestConformance_Drained_*`, `TestConformance_DeleteWritesExactlyOneDeletionLogRow`, `TestConformance_DeleteExpired_AlreadyCancelledContextDeletesNothing` — all confirmed present during LT-42's full completeness sweep). This story is the **caller**: a scheduled invocation that loops per `RetentionClass` until drained, plus a subject-deletion request path, plus the health metric that tells 04 whether it's actually running.\n\n**Mechanism (team-lead's recommendation, adopted):** a `CronJob` in `04-infra-devops`'s manifests invoking `cmd/api-service`'s existing image in a new `--sweep` mode (or a distinct small entrypoint, `03`'s call) — not a new binary, not a new image build, reusing what's already deployed.\n\n## The three retention classes and windows this sweep must implement (from `pii-governance.md`, cited so this story doesn't re-derive them)\n\n| `RetentionClass` | Clock | Window | Why this clock specifically |\n|---|---|---|---|\n| `direct` | `updated_at` | 24 months | Proposed POC default, engineering basis only — explicitly **not** a legal ruling (`pii-governance.md`'s own \"unknown, needs product/legal ruling\" status). This story implements the number as configured, doesn't treat it as settled policy. |\n| `idp_cache` | `updated_at` | 30 days | A cache, not a record — re-hydration costs one `/identity` call, so the window trades staleness against re-fetch cost. |\n| `idp_cache_orphan` | `created_at`, **deliberately not `updated_at`** | 7 days | Using `updated_at` would let an orphan's own read/re-hydration path reset its expiry indefinitely — the entire reason this class exists as `created_at`-clocked, not a stylistic choice. |\n\n**These are stated as \"Proposed\" in `pii-governance.md`, not \"Ruled,\" except `user_credential`'s no-independent-window rule.** This story implements the configured numbers; it is not this story's job to decide whether 24 months/30 days/7 days are the right numbers — that's Priya's/legal's call, already flagged as open in the source document.\n\n## Acceptance criteria (restated from `backlog.md` S11)\n\n- [ ] Implements 05's addendum without re-deriving the transaction-boundary or batching reasoning (each `DeleteExpired` call is already one transaction per batch, per the DAO's own implementation).\n- [ ] Loops `DeleteExpired` per `RetentionClass` until `Drained` is true, one class at a time, never a mixed/shared predicate — enforcement site: the sweep invocation loop's own structure.\n- [ ] `DeleteExpired` is never called with a request-scoped context — the sweep's own job/scheduler context governs it. Enforcement site: the sweep invocation's context construction (the `CronJob`'s own pod lifecycle, not an inbound HTTP request), plus a test asserting an already-cancelled context returns before deleting anything (the DAO layer already has this test per LT-38; this story's own test confirms the *caller* doesn't accidentally pass a request-scoped one).\n- [ ] `SweepResult.OldestSurvivingAt` is published to 04's observability **only from a `Drained == true` result** — a non-drained batch reports progress, not health, per `observability.md`'s explicit warning that getting this wrong \"means the alert fires on every sweep and gets muted, which is worse than not having it.\" Enforcement site: the metrics-emission code path, gated on `Drained`.\n- [ ] Metrics emitted per class per run: `rows_examined`, `rows_deleted`, `oldest_surviving_row_age_seconds{class=\"direct\"|\"idp_cache\"|\"idp_cache_orphan\"}` — matching `observability.md`'s exact label values (not the earlier-corrected, invented `vendor_token_cache`/`idp_identity_cache` names that document itself flagged and fixed).\n- [ ] `DeleteProfile` is the only path used for a subject-deletion request; ordinary application deletes still go through `Profiles().Delete` (no log row) — this distinction is preserved, not collapsed for convenience.\n- [ ] The `Drained`/`OldestSurvivingAt` coupling gets a one-line doc comment at the field declaration (Oren's note) — already present in the DAO's own code per LT-42's completeness sweep; this story doesn't need to add it again, just not remove or contradict it.\n- [ ] **The `CronJob` runs against `api-service`'s existing image** (a `--sweep` mode or distinct entrypoint), not a new image build — matching team-lead's stated \"half-day story\" framing; a new image/Dockerfile would be disproportionate scope for what this needs.\n- [ ] **Bounded by the existing `maxRows` per call** — the sweep doesn't invent a new batching parameter; it uses the DAO's own already-validated `1..10_000` bound.\n- [ ] **Audited** — every deletion this sweep performs writes exactly one `deletion_log` row via the DAO's own transaction (already guaranteed by the DAO layer per LT-38's test); this story's job is only to confirm it doesn't bypass that path.\n\n## Non-goals\n\n- No new DAO methods, no schema changes — `DeleteExpired`/`DeleteProfile` and `deletion_log` already exist and are tested.\n- No change to the retention windows themselves (24 months/30 days/7 days) — those are Priya's/legal's numbers, implemented as configured, not re-litigated here.\n- No new container image — reuses `api-service`'s existing image in a new invocation mode.\n- No subject-deletion-request *API endpoint* — `backlog.md`'s S11 wires the DAO-level `DeleteProfile` path; whether/how an external caller triggers a subject-deletion request (a support-tool button, an API route) is a separate, unscoped question not raised by this story's own criteria.\n\n## PO review script\n\n1. Confirm the `CronJob` manifest invokes `api-service`'s existing image, not a new one.\n2. Confirm the sweep loop calls `DeleteExpired` per class until `Drained`, never a mixed predicate — read the invocation code directly.\n3.

28:## Story 2 — Deliver secrets to both services per 02's inventory (LT-46)
29-
30-**Description:** Implement the Kubernetes-native `Secret` delivery mechanism in `./secrets-delivery.md`: file-mounted secrets keyed by name only in manifests, RBAC scoped per-service (and, for the JWT signing key, scoped to the issuing code path specifically, not `api-service`'s verification path), cluster-level encryption-at-rest for the `Secret` resource type, and the migration-runner credential's backend-specific provisioning (`CREATE EXTENSION pg_trgm` rights on PostgreSQL only, nothing extra on CockroachDB, no privilege model on SQLite) kept distinct from the runtime service credential (DML-only, no DDL, per 05's R4).
31-
32-**Acceptance criteria:**
33-- [ ] 02 (the hand-off's author) confirms this implementation matches `handoff-04-secrets.md` v2's inventory without needing to re-explain any row.
34-- [ ] No `Secret` value appears in a manifest, image layer, build arg, or CI log — enforcement site: manifests reference names only; CI's `gitleaks` stage (Story 3).
35-- [ ] No ServiceAccount can `get`/`list` a `Secret` it doesn't mount — enforcement site: per-service `Role`/`RoleBinding` scoped to named `Secret`s.
36-- [ ] The migration-runner credential and the runtime service credential are provisioned as two distinct `Secret`s, never one — enforcement site: separate `Secret` objects, separate `Role`s, per 05's R4.
37-- [ ] `Secret` resources are encrypted at rest in etcd — enforcement site: cluster `EncryptionConfiguration`.
38-
39-**Depends on:** 02 — `handoff-04-secrets.md` (received, v2, final); 05 — `migration-approach.md` R4 (final).
40-
41-**Model/effort:** Sonnet, medium.
42-
43-**Type:** Story.
44-
45-**Labels:** `track-04`, `security-graded`, `no-code-yet`.
46-
47-## Story 3 — CI/CD pipeline: build, lint, test, scan, migrate, describe-only deploy (LT-47)

  "content": "# LT-46 refinement — Story 2: secret delivery, re-scoped to Vault\n\n**Product Owner:** Naomi Voss (01). **Research team:** Imogen Hale, Desmond Okafor, Tobias Lindqvist. **Engineering:** Theo Bergman (04, manifests); provisioning: Amber (Vault itself); review: Marcus Ilori (02, Vault policies).\n\n**Who did the work:** Refined by Naomi Voss (PO); Warren's ruling on the re-scoped criterion.\n\n## Why this changed\n\n`backlog.md`'s original Story 2 criterion 5 required Kubernetes `Secret` resources encrypted at rest in etcd, enforced via cluster `EncryptionConfiguration` — a control-plane setting on Warren's own shared cluster (confirmed absent when checked directly: no encryption-provider config on the kube-apiserver). Escalated to Warren as accept-residual-or-enable-and-reverify; **his ruling: neither — move application secrets out of Kubernetes `Secret` objects entirely**, into the cluster's existing Vault, delivered via the Vault Agent Injector. This closes the original concern more completely than encrypting `Secret`s at rest would have (a Vault-delivered secret is never written to etcd as a `Secret` object in the first place, not merely encrypted once there) and reuses infrastructure that already exists on this cluster rather than requiring a control-plane change on a shared box outside this project's authority.\n\n## Re-scoped criterion (replaces the original etcd-encryption line)\n\nApplication secret material is not stored in etcd; delivered by Vault Agent with per-`ServiceAccount` Vault roles. Enforcement site: Vault policy per role, plus a namespace check that none of the six application `Secret`s exist.\n\n## The six application secrets this criterion covers (enumerated directly from the deployed manifests, not assumed)\n\n1. `api-service-jwt-signing-key` — the JWT signing private key, currently mounted only into `api-service-issuer` (LT-32's F13 fix).\n2. `postgres-superuser` — consumed only by the Postgres `StatefulSet` itself.\n3. `db-migrator-credential` — the migration-runner credential (DDL rights), consumed by the migration `Job`.\n4. `db-runtime-credential` — the runtime service credential (DML-only), consumed by `api-service`.\n5. `issuer-db-migrator-credential` — the issuer's own migration-runner credential (client-store schema).\n6. `issuer-db-runtime-credential` — the issuer's own runtime credential, consumed by `api-service-issuer`.\n\n**Accepted platform exceptions, named explicitly rather than silently grandfathered in as Kubernetes `Secret`s:**\n- `postgres-server-tls`, `loginid-takehome-tls` — both `cert-manager`-issued TLS certificates. `cert-manager`'s own design outputs a Kubernetes `Secret`; that's the standard integration pattern for this cluster (every other app on it uses the same mechanism per `decisions/deploy-path.md`), not an application secret this project introduced, and not in scope for the Vault migration.\n- **Open question, flagged rather than assumed either way:** `qa-client-credential` (the review-only QA client credentials from LT-51/LT-41's joint review) — is this an \"application secret\" that should also move to Vault, or an ops/review-tooling artifact that can reasonably stay a Kubernetes `Secret`? Not decided here; flagging for Theo/Marcus to rule during implementation, named so it isn't silently omitted from either list.\n\n## Acceptance criteria for this re-scoped piece\n\n- [ ] All six application secrets above are delivered via Vault Agent Injector sidecar/init-container pattern, with a distinct Vault role per consuming `ServiceAccount` — matching the existing per-service RBAC-scoping discipline this project already applies to Kubernetes `Secret`s (never one shared credential across services).\n- [ ] A namespace check (manual `kubectl get secret -n loginid-takehome` or a CI/audit script) confirms none of the six names above exist as Kubernetes `Secret` objects post-migration.\n- [ ] Vault policies are scoped per-role to exactly the path(s) that role's service needs — no policy grants broader read access than the specific secret(s) that `ServiceAccount` consumes, mirroring the existing \"no ServiceAccount can get/list a Secret it doesn't mount\" discipline (`backlog.md`'s own criterion 3, unaffected by this change).\n- [ ] The migrator/runtime credential separation (criterion 4, unaffected) is preserved under Vault — two distinct Vault paths/roles, not one shared secret with two consumers.\n- [ ] The `qa-client-credential` disposition (Vault or stays-as-Secret) is explicitly decided and stated, not left ambiguous.\n- [ ] Marcus (02) reviews the Vault policies before this is called Done — same review discipline already applied to every other security-graded surface in this project.\n\n## Non-goals\n\n- No change to the TLS-certificate delivery mechanism (`cert-manager` → Kubernetes `Secret` stays as-is) — explicitly out of scope, named as an accepted platform exception above.\n- No change to the CI runner's own RBAC (still zero grants on `secrets`, already correct and unaffected by where the secrets themselves live).\n- No re-litigation of which secrets exist or what they're for — this story is a delivery-mechanism change, not a secrets-inventory redesign.\n\n## PO review script\n\n1. Confirm Vault Agent Injector annotations/sidecars are present on each consuming Deployment/StatefulSet/Job.\n2. `kubectl get secret -n loginid-takehome` — confirm none of the six named application secrets appear; confirm the two named TLS-certificate exceptions and the `qa-client-credential` disposition are the only ones present (or absent, per whatever was decided).\n3. Confirm each Vault role's policy is scoped to exactly its consuming service's own secret path(s) — read the policy directly, not inferred from the manifest alone.\n4. Confirm Marcus's review of the Vault policies happened and is recorded.\n5. Once deployed: re-review live, per team-lead's own stated plan — confirm the running pods actually receive secret material via Vault Agent (a file mount from the injector sidecar), not a fallback to an old Kubernetes `Secret` left in place by mistake.\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"

Counter-proposal accepted: a fail-loud criterion (visible `CrashLoopBackOff`, not a silent indefinite `Init` hang) plus a PO-script step that deliberately forces an injector failure and confirms it's visible.\n\n**Naomi Voss — ruling:** Both fixes applied.

{"body":"## Summary\n\nThe story that makes Q2 (api-service) and Q3 (idp-connector) one system, per `03-engineering-delivery/refinement/LT-33.md`.\n\nNew `internal/onboarding` package:\n- `TokenSource` caches api-service's own connector-scoped client-credentials token per-replica, refreshing before TTL or on an explicit `Invalidate` (Marcus Ilori's (02) caching correction to this refinement's original draft: our own client token, standard OAuth2 client-credentials practice — a different risk class from the vendor token, which is correctly never cached).\n- `HTTPConnectorClient`/`HTTPTokenClient` implement the real outbound HTTP calls, mirroring `internal/connector.HTTPVendorClient`'s own discipline: bounded connection pool, fresh headers built per call, no client-level token state.\n- `Service.VerifyIdentity` bounds each connector call with `context.WithTimeout` plus a small fixed retry-with-backoff on genuine unreachability (`ErrIdentityVerificationUnavailable` — no internal detail ever surfaced), while a genuine vendor-credential rejection is distinguishable (`ErrVendorCredentialRejected`). An ambiguous 401 (our token vs. the vendor's — idp-connector's own uniform-response design can't tell) triggers exactly one invalidate-and-retry of the whole flow before concluding the vendor credential was the problem. Own-token-acquisition failures are logged as a distinct class from connector-unreachable failures, per this story's own criterion.\n\nNo new public HTTP endpoint (this story's own non-goal, and PO review script item 7): wired into `cmd/api-service/main.go`'s verifier branch best-effort, the same \"fail this one capability closed, not the whole binary\" pattern the existing DAO-repository/pingDB handling already uses.\n\n`config.go`: `CONNECTOR_CLIENT_ID`/`SECRET` now resolve via `*_FILE` precedence (same pattern as `DB_DSN_FILE`), per the PM's relay of Warren's approval to move to Vault Agent Injector delivery (LT-46) without this code caring which mechanism wrote the file. Two new env vars: `ISSUER_TOKEN_URL`, `IDP_CONNECTOR_BASE_URL` — documented in root `PLANNING.md`. Both, plus the connector credential, are classified in `config.OptionalEnvVars` (not folded into `RequiredAuthEnvVars`: that function's simple presence-check model doesn't fit the `*_FILE` resolution pattern — presence is validated at the point of use, `internal/onboarding.NewTokenSource`).\n\n**Flag for Theo (04):** api-service's verifier Deployment manifest needs `ISSUER_TOKEN_URL`, `IDP_CONNECTOR_BASE_URL`, and the connector client credential wired in before this capability is reachable in-cluster — `newOnboardingService`'s own startup log says \"not available\" until then, by design.\n\n## Verification\n\n- `go build ./...`, `go vet ./...`, `go test ./...` — all clean.\n- `staticcheck ./...`, `gofmt -l` — clean.\n- `gitleaks detect` — clean.\n- `internal/onboarding/onboarding_test.go`: token caching/refresh/invalidation, happy path (token flows from `Aut

Separately, Marcus noted the underlying gap this surfaced — `RequiredAuthEnvVars`'s "bare non-empty literal" model doesn't understand the `*_FILE`-takes-precedence shape `DB_DSN`/`DB_DSN_FILE` already has, independent of this story — is worth generalizing as its own small follow-up (not blocking this PR): teach `RequiredAuthEnvVars`/its callers "either X or X_FILE must resolve" once, rather than special-casing it per variable as more show up.

Matches the \"scoped to the narrowest function\" criterion exactly.\n- **Header, not body:** `client.go` sets `X-Vendor-Access-Token` via `req.Header.Set`, a fresh `*http.Request` per call (matching the connector's own already-established discipline), never in the JSON body.\n- **Never-log:** read every `fmt.Errorf`/`log.Printf` call site in both `onboarding.go` and `client.go` — none references `vendorUsername`, `vendorPassword`, `ourToken`, `vendorAccessToken`, or the client secret; only status codes and generic descriptions.\n- **Fail-closed, generic upward failure, failure-class distinction:** confirmed both in code and by the two distinct log messages observed running the tests — `ErrIdentityVerificationUnavailable` (connector-unreachable) vs. the own-token-acquisition path, logged separately per the story's own criterion.\n- **`ux-notes.md:27` agreement:** unchanged, still matches — no divergence introduced by this implementation.\n- **No new public HTTP endpoint:** confirmed — `VerifyIdentity` isn't wired to any handler yet, per the PR's own stated non-goal and this refinement's own PO-script item 7.\n\n**On Marcus's disposition (unenforced connector config acceptable with no consumer, hard-blocking for whichever story wires a real handler to this):** agreed, not just accepted. `NewTokenSource` already fails fast on missing credentials at *construction* time (`TestNewTokenSource_RequiresCredentials`) — the \"unenforced\" gap is specifically that nothing currently constructs/wires this service into a live request path at all, not that validation is skipped once it is.

6	
7	## Why this one, why it matters more than most
8	
9	Per team-lead: this is the document LoginID reads first — the submission's front door — and it should be written by someone who watched the process, not generated at the end from a summary of a summary. Depends on S1–S9, all of which are now Done or in their final pass, so this is genuinely ready to write for real, not from a plan.
10	
11	## What "implemented vs. stubbed" actually is, checked directly rather than assumed
12	
13	**Real, live, deployed:**
14	- Full DAO layer against real Postgres (LT-35/36/38 — all Done, verified live against the deployed database and in CI against real Postgres/CockroachDB service containers).
15	- REST search/retrieve handlers (LT-39 — Done), auth middleware (LT-40), real token issuance (LT-51 — refined, in progress), all verified live at `https://loginid-takehome.uplifttech.org` with real minted tokens.
16	- The connector's own inbound `/auth`/`/identity` contract (LT-41 — Done, verified in-cluster via port-forward with a real vendor stub backing it).
17	- CI/CD (LT-47), containerization (LT-45), secrets delivery (LT-46), database provisioning (LT-52) — all Done, deployed, live.
18	
19	**Deliberately stubbed, and why — this is the section a cold reader needs, stated plainly, not left to infer:**
20	- **The third-party vendor (ABC/XYZ) is an in-process `StubVendorClient`**, not a real HTTP integration — `idp-connector` falls back to it when `IDP_ABC_BASE_URL` is unset, logs this explicitly on startup, and this is `backlog.md`'s own stated non-goal for LT-41 ("no real vendor integration"). The assignment names the vendor generically; a real integration was never in scope.
21	- **The `authorize()` object-level policy hook is a `StopgapAuthorizer`**, not the real caller-referral datastore `handoff-03-auth.md`'s F8 resolution describes — a stated seam, not a hidden gap, per LT-39/LT-40's own non-goals.
22	- **CockroachDB and SQLite are exercised in CI only, never deployed live** — only Postgres runs in the actual cluster (LT-52's explicit scope limit). A reader should not expect to find CockroachDB running anywhere.
23	- **No `POST /profiles` write endpoint exists or is planned** — Q2 is search/retrieve by the assignment's own text; a write path was ruled out as scope creep (team-lead + Priya's decision, recorded on LT-39). Review/demo data enters via a version-controlled, idempotent SQL file (`deploy/demo-data/001-review-profiles.sql`) applied as a documented runbook step, not through the API.
24	- **Rate limiting, the touch counter, and the token-issuer's grant limiter are in-process, single-replica-only** — their own code comments state a shared store (Redis) is needed for a genuine multi-instance deployment; this project runs `api-service`/`api-service-issuer` at 1 replica with `Recreate` rollout strategy specifically so this simplification holds correctly, not silently degrading under a rolling update (a real live-tested bug this project found and fixed, not a hypothetical).
25	- **`api-service` calling the connector (LT-33)** is in progress as of this writing — the piece that makes Q2 and Q3 one system, not yet merged.
26	- **The retention sweep (LT-44) — designed and enforced at the schema/DAO level, not yet operationally running.** `DeleteExpired`/`DeleteProfile` exist on the DAO composite and are tested there, but nothing schedules or calls them; no cron/job wires the sweep to run against the live database. `pii-governance.md`'s retention policy is a real, tracked, backlogged story (S11/LT-44), not a silently-abandoned requirement — but a cold reader checking whether retention/deletion actually runs in production would otherwise have to discover its absence themselves.
27	
28	## Acceptance criteria (restated from `backlog.md` S10)
29	
30	- [ ] A cold reader can tell what runs vs. what's a stub without asking — same bar as every hand-off in this project. The "deliberately stubbed" list above is the actual content this criterion requires; the README section should be at least this specific, not a vaguer restatement.
31	- [ ] Test-strategy section states: unit-heavy, integration deliberately stubbed (the assignment doesn't require full end-to-end); the same-PR fake-update rule from `decisions/test-double-strategy.md`, **now also a literal checklist line in `.github/pull_request_template.md`** (LT-42's fix — cite both, since the design doc alone was found insufficient during this project's own review).
32	- [ ] AI tooling note names the actual model/effort tier per story, not just "Claude Code was used": `sonnet, high` for every implementation story in this track's backlog except the connector (`opus, high` — the one seat above sonnet, per `planning-approach.md`'s connector-token-lifecycle exception, because a subtle bug there directly contradicts this project's own threat model). Names the actual orchestration patterns run and what they produced: `decisions/go-layout-debate.md` (package/binary-split decision), `decisions/error-semantics.md` (rotating devil's-advocate, Oren's objections), `decisions/context-propagation.md` (deadline-budget ruling), `decisions/test-double-strategy.md` (hand-written-fakes ruling, Marisol's mitigation). This project is also an org-orchestration exercise across five tracks with hired sub-teams (`PLAN.md`, `CASTING.md`) — worth one sentence acknowledging that's the broader structure this track's own patterns sit inside, without re-explaining the whole org here (that's `../CLAUDE.md`'s job).
33	- [ ] **Added — real, live-tested findings worth naming precisely, not just the design-time patterns.** This track's own PO review (a Product-track lead running live acceptance checks against the deployed system, not just code review) found and helped fix four real production-shaped bugs — named individually and precisely (per Tobias's objection, which correctly caught an early draft conflating two of these into one mislabeled bullet), not lumped together:
34	  1. A CI coverage gap where `pr-check` silently skipped every Postgres and CockroachDB conformance test (only SQLite genuinely ran), reading as a green build with two of three backends unproven.
35	  2. A cross-replica rate-limiting bug in `api-service`'s own resource-API rate limiter, reproduced by actually crossing the 10 req/min cap live against 2 running replicas.
36	  3. `api-service`'s own Q2 token issuer/verifier wiring shipped with `AUTH_JWT_ISSUER`/`AUTH_JWT_AUDIENCE` unset in its manifest — minted tokens carried no `iss` and were checked against an empty `aud`, silently "verifying" for the wrong reason.
37	  4. A **separate, later** total outage in `idp-connector`'s (Q3's) own inbound auth — its Deployment manifest never set `AUTH_JWKS_URL` at all, so every request, including a genuinely valid token, failed identically with a JWKS-fetch error. Distinct from #3: a different service (the connector, not `api-service`), a different missing variable, found in a separate in-cluster review pass.
38	Naming these precisely, not vaguely, is itself evidence of the process the AI-workflow note should describe: verification against the live, deployed system, not only against a test suite or a design doc — and getting the subsystem right matters, since this project's own vocabulary (`idp-connector` = Q3, `api-service`/`api-service-issuer` = Q2) carries real information a cold reader relies on.
39	
40	## Non-goals
41	
42	- No re-explanation of the org-wide orchestration structure (leads, hires, `CASTING.md`) — that's the root `CLAUDE.md`'s and `LOG.md`'s job; this README covers track 03's own AI-workflow story specifically.
43	- No new code, no new tests — this is a documentation story.
44	- No speculative "future work" section beyond what's already named as a stated seam elsewhere (`StopgapAuthorizer`, the vendor stub, Redis for multi-instance) — don't invent a roadmap this project hasn't committed to.
45	
46	## PO review script
47	
48	1. Read the README's "implemented vs. stubbed" section cold, as an evaluator would: can every item in the "deliberately stubbed" list above be found stated plainly, with a reason, not just a bare "TODO"?
49	2. Confirm the test-strategy section cites both `decisions/test-double-strategy.md` and the PR-template checklist line — not just the design doc alone (the exact gap LT-42 found).
50	3. Confirm the AI-workflow note names actual model/effort tiers per story (spot-check against `backlog.md`'s own `Model/effort:` lines) and actual orchestration-pattern outcomes (spot-check against the cited `decisions/*.md` files), not generic claims.
51	4. Confirm all four live-review findings (CI skip; rate-limit/replica bug; `api-service`'s issuer/verifier config gap; `idp-connector`'s separate JWKS outage) are named individually and correctly attributed to the right subsystem, not omitted or conflated — a submission that only shows the clean end-state, with none of the process that found real bugs, undersells the actual work done.
52	
53	## Research team review
54	
55	**Desmond Okafor — claims check:** Verified model/effort claims exactly against `backlog.md` (11 `sonnet, high`, exactly one `opus, high` — the connector, matching `planning-approach.md`'s exception language). Verified the PR-template fix, the `Recreate`-strategy fix (confirmed actually merged, not still-open), and the `idp-connector` JWKS outage as a real, merged incident (PR #48). Everything else in the "deliberately stubbed" list confirmed against code inspected in earlier passes. **One real omission found:** the retention sweep (LT-44/S11) is missing from the list entirely — `DeleteExpired`/`DeleteProfile` exist only on the DAO interface and in test fakes, no `cmd/` caller, no `CronJob` manifest anywhere; a real, tracked, backlogged story with zero operational wiring, the same class of gap as the other stubbed items. Added with his exact wording.
56	
57	**Tobias Lindqvist — objection:** The original draft's third "live finding" bullet mislabeled a real `api-service` (Q2) issuer/verifier config bug as a "connector-auth outage," which points a cold reader at the wrong subsystem (`idp-connector`/Q3, never involved in that specific incident). Checked against my own LT-41.md record and confirmed: there's a second, genuinely separate incident that *is* a real `idp-connector` outage (missing `AUTH_JWKS_URL` in its own manifest, verified directly via port-forward against the connector itself) — both are real, distinct, and now named individually and correctly attributed rather than conflated into one vaguely-worded bullet. Confirmed and approved once the split was applied.
58	
59	**Naomi Voss — ruling:** All fixes applied — LT-44 added to the stubbed list, the two distinct auth incidents split and correctly attributed to their actual subsystems. This refinement is accepted and ready to hand off. The precision Tobias insisted on here matters for exactly the reason he named: this is the one document evaluators read first, and getting "which subsystem broke" right is itself evidence of the same rigor this whole review chain has been running.

1	# Track 03: Engineering & Delivery
2	
3	Go implementation of all three assignment questions — the DAO layer (Q1), the REST search/retrieve API with authentication (Q2), and the third-party identity connector (Q3) — plus the glue between Q2 and Q3. See root `../CLAUDE.md` for the full assignment text and how this track fits the other four; this file covers only what this track built, what's stubbed, and how.
4	
5	## What's implemented — live, deployed, verified against the running system
6	
7	- **Q1 — DAO layer** (`internal/dao`, `internal/dao/postgres`, `internal/dao/sqlite`): `user_profile`/`user_credential` storage behind one `Repository` interface, real implementations for Postgres/CockroachDB and SQLite. Verified against the actually-deployed Postgres database, and in CI against real Postgres and CockroachDB service containers (not mocked) — a cross-backend conformance suite (LT-38) asserts all three backends behave identically, not just that their Go signatures match.
8	- **Q2 — REST API** (`internal/api`, `internal/app`): `POST /profiles/search`, `GET /profiles/{id}`, and a real RFC 6749 client-credentials `POST /auth/token` grant, all behind RS256 JWT verification. Verified live at `https://loginid-takehome.uplifttech.org` with real minted tokens, including rate-limiting, masked-vs-full-read scoping, and pagination.
9	- **Q3 — connector** (`internal/connector`, `cmd/idp-connector`): the third-party IDP connector's own inbound `/auth`/`/identity` contract. Verified in-cluster via `kubectl port-forward` with a real vendor stub backing it — happy path, audience rejection, fail-closed identical-content error responses, a timing floor on the three internal failure branches, and a failure-ratio rate limiter actually firing under a live failed-auth burst, not just asserted in a unit test.
10	- **api-service → idp-connector integration** (`internal/onboarding`, LT-33): api-service's own outbound call to the connector, closing the loop between Q2 and Q3 — its own cached, refreshed OAuth2 client-credentials token; bounded timeouts and retry-with-backoff on connector calls; a generic upward failure on any connector-unreachable condition, with own-token-acquisition failures logged as a distinct class.
11	- CI/CD, containerization, secrets delivery, and database provisioning (04's stories, LT-45/46/47/52) are all Done and live — `pr-check` runs this track's tests against real Postgres and CockroachDB service containers on every PR, not just SQLite.
12	
13	## Deliberately stubbed — stated plainly, not left to infer
14	
15	- **The third-party vendor (ABC/XYZ) is an in-process `StubVendorClient`**, not a real HTTP integration. `idp-connector` falls back to it whenever `IDP_ABC_BASE_URL` is unset, and says so explicitly on startup. The assignment names the vendor generically — a real integration was never in scope (`refinement/LT-41.md`'s own stated non-goal).
16	- **The `authorize()` object-level policy hook is a `StopgapAuthorizer`**, a hard-coded, default-deny stand-in — not the real caller-referral datastore `../02-ai-security-architecture/handoff-03-auth.md`'s own design describes. A stated seam, not a hidden gap.
17	- **CockroachDB and SQLite are exercised in CI only, never deployed live.** Only Postgres runs in the actual cluster (LT-52's explicit scope limit) — don't go looking for a running CockroachDB instance anywhere.
18	- **No `POST /profiles` write endpoint exists or is planned.** Q2 is search/retrieve by the assignment's own text; a write path was ruled out as scope creep. Review/demo data enters via a version-controlled, idempotent SQL file (`deploy/demo-data/001-review-profiles.sql`), applied as a documented runbook step, never through the API.
19	- **Rate limiting, the touch counter, and the token issuer's grant limiter are in-process and single-replica-only.** Their own code comments say a shared store (Redis) would be needed for a genuine multi-instance deployment — this project runs `api-service`/`api-service-issuer` at 1 replica with a `Recreate` rollout strategy *specifically* so this simplification holds correctly rather than silently degrading under a rolling update. That constraint exists because of a real bug this project found live (see below), not as a hypothetical caveat.
20	- **The retention sweep (LT-44) is designed and enforced at the schema/DAO level, but not yet operationally running.** `DeleteExpired`/`DeleteProfile` exist on the DAO composite and are tested there directly; nothing yet schedules or calls them against the live database. `../05-data-ops/pii-governance.md`'s retention policy is a real, tracked, backlogged story, not an abandoned requirement.
21	
22	## Package layout
23	
24	`cmd/api-service` and `cmd/idp-connector` are both thin wrappers — argument parsing and `main()` only. Route registration and config loading live once, in `internal/app` and `internal/config`, shared by both binaries rather than duplicated per binary (see `decisions/go-layout-debate.md` below). `internal/api` holds Q2's HTTP handlers, JWT middleware, rate limiting, and the token issuer; `internal/connector` holds Q3's inbound handlers and outbound vendor client; `internal/onboarding` holds LT-33's mediating client from `api-service` to the connector; `internal/dao` and its `postgres`/`sqlite` subpackages hold Q1, behind one `Repository` interface `internal/dao/conformance` tests identically across backends.
25	
26	## Test strategy
27	
28	Unit-heavy; integration deliberately stubbed where the assignment itself doesn't require full end-to-end coverage. Hand-written interface fakes, not generated mocks, for DAO/handler tests (`decisions/test-double-strategy.md`) — small enough interfaces that a fake struct per test case beats adopting a codegen dependency at this project's scale. The rule that any change to `dao.Repository` (or its sub-interfaces) updates its hand-written fake in the same PR is now a literal checklist line in `.github/pull_request_template.md`, not just prose in a design doc — LT-42's own review found the design doc alone insufficient (a PR landed an interface change without updating its fake, caught only in a later pass), so the checklist line is the actual enforcement site now, and the design doc explains why. Real-backend correctness (Postgres/CockroachDB/SQLite conformance, the CockroachDB serialization-retry path) is proven against real databases, in CI, not mocked — `internal/dao/conformance`'s own suite is the one enforcement site for "do the backends behave alike," distinct from a signature-matching test that proves nothing about behavior.
29	
30	## AI tooling and workflow
31	
32	Every implementation story in this track's backlog runs at `sonnet, high` except the connector (`idp-connector`'s `/auth`/`/identity`, Q3), which runs at `opus, high` — the one seat above sonnet in this track, per `../02-ai-security-architecture/planning-approach.md`'s connector-token-lifecycle exception: a subtle bug in that specific code path (a leaked or misscoped vendor token) directly contradicts this project's own threat model in a way most of this track's other code doesn't.
33	
34	Beyond model selection, implementation decisions in this track ran through structured adversarial review rather than being decided unilaterally:
35	- `decisions/go-layout-debate.md` — a three-hats debate (optimist/pessimist/pragmatist) on one binary vs. two, ruling to keep two binaries (already published and built against by 04) but merge the *authoring* cost via a shared `internal/app` package, plus a concrete requirement (bounded timeouts, no tight-looping retries on outbound calls) adopted from the pessimist's production-incident pattern-matching.
36	- `decisions/error-semantics.md` — a rotating devil's-advocate pass (Oren Castellan) that closed the sentinel-error set, forced a translation boundary so wrapped DB errors never leak driver text to an API client, and added explicit handling for `context.DeadlineExceeded`/`Canceled`.
37	- `decisions/context-propagation.md` — a second rotating devil's-advocate pass (Nolan Reyes, drawing on production-incident pattern-matching) that scoped multi-statement writes to a transaction under context cancellation, and named which write paths deliberately detach from the inbound context for durability.
38	- `decisions/test-double-strategy.md` — a third rotating devil's-advocate pass (Marisol Ferran) that weighed hand-written fakes against generated mocks; hand-written fakes stood, with the interface-drift risk closed procedurally (the PR-template checklist line above), not by adopting a codegen tool.
39	
40	This project is also a broader org-orchestration exercise — a PM agent coordinating five track leads, each running a small hired sub-team with deliberately varied personalities, using patterns like adversarial pairs, red/blue, and structured written debate (`../PLAN.md`, `../CASTING.md`) — the four decisions above are this track's own instance of that same structure, not a separate practice invented for engineering work alone.
41	
42	## Real, live-tested findings
43	
44	This track's own delivery process included live acceptance review against the actually-deployed system, not only code review and unit tests — and that process found and helped fix four real, distinct production-shaped bugs, each named individually rather than lumped together:

46	1. **A CI coverage gap**, where `pr-check` silently *skipped* every Postgres and CockroachDB conformance test — only SQLite genuinely ran — while still reporting an overall green build. Fixed two ways: real Postgres/CockroachDB service containers added to the CI job, and every affected test fixture changed to fail loudly (not skip) when a required backend DSN is absent specifically in CI.
47	2. **A cross-replica rate-limiting bug** in `api-service`'s own resource-API rate limiter, reproduced by actually crossing its 10 req/min cap live against 2 running replicas — each replica's in-process limiter had no visibility into the other's request count, so the effective cap was silently doubled. Fixed by moving `api-service`/`api-service-issuer` to a single replica with a `Recreate` rollout strategy (04's story), a deliberate scope limit stated plainly above, not a silent workaround.
48	3. **`api-service`'s own Q2 token issuer/verifier wiring shipped with `AUTH_JWT_ISSUER`/`AUTH_JWT_AUDIENCE` unset** in its Kubernetes manifest — minted tokens carried no `iss` and were checked against an empty `aud`, "verifying" successfully for the wrong reason rather than failing loudly. Fixed in the manifest, plus a startup check (`cmd/api-service`) that now refuses to start with either unset, and a URL-shape check on the JWKS/issuer values specifically (a non-empty but garbage value is caught too, not just an absent one).
49	4. **A separate, later total outage in `idp-connector`'s (Q3's) own inbound auth** — its Deployment manifest never set `AUTH_JWKS_URL` at all, so every request, including a genuinely valid token, failed identically with a JWKS-fetch error. Distinct from finding 3: a different service, a different missing variable, found in a separate in-cluster review pass. Fixed the same way: the manifest, plus a startup check in `cmd/idp-connector` itself, plus a systemic test (`internal/config`'s manifest-vs-config test) that now parses every real Kubernetes Deployment manifest and asserts it sets everything its own mode requires — closing this specific class of gap structurally, in CI, rather than relying on a fourth live incident to catch the next occurrence.
50	
51	Naming these precisely — which subsystem, which variable, which fix — is itself part of what this AI-workflow note is meant to demonstrate: verification against the live, deployed system, not only against a test suite or a design doc.

  "description": "Claims-check LT-43 README",
  "prompt": "You are Desmond Okafor, claims auditor for track 01. Naomi (PO) needs a claims check on the newly-written `03-engineering-delivery/README.md` (Renata's LT-43 deliverable, PR merged as commit 541235c, in the actual Go repo cloned at /tmp/lt34review — NOT this docs-only working tree, which doesn't have the Go source).\n\nTask: verify every checkable factual claim in the README against ground truth in /tmp/lt34review (run `git fetch && git reset --hard origin/main` first if it looks stale — HEAD should be 541235c). Specifically:\n\n1. **Model/effort claims**: README says every implementation story in 03's backlog runs `sonnet, high` except the connector (`opus, high`). Check this against `03-engineering-delivery/backlog.md`'s own `Model/effort:` lines (in the docs tree at /Users/warrenthompson/Source/LoginID/03-engineering-delivery/backlog.md) — count how many stories say `sonnet, high` and confirm exactly one (the connector) says `opus, high`.\n\n2. **Decision docs cited**: README cites `decisions/go-layout-debate.md`, `decisions/error-semantics.md`, `decisions/context-propagation.md`, `decisions/test-double-strategy.md` with specific claimed outcomes (three-hats debate ruling to keep two binaries but share `internal/app`; Oren's rotating devil's-advocate closing the sentinel-error set; Nolan's pass on transaction/context-cancellation scoping; Marisol's pass on hand-written fakes vs codegen). Read each file (in /tmp/lt34review/decisions/ or wherever they live in that repo) and confirm the README's summary of each matches what the file actually says — not just that the files exist.\n\n3. **PR template claim**: confirm `.github/pull_request_template.md` exists in /tmp/lt34review and contains a literal checklist line about updating hand-written fakes when `dao.Repository` (or sub-interfaces) changes in the same PR.\n\n4. **The four live-tested findings** (CI skip fixed via real service containers + fail-loud fixtures; cross-replica rate-limit fixed via 1-replica + Recreate; api-service issuer/verifier AUTH_JWT_ISSUER/AUTH_JWT_AUDIENCE fix + startup check + URL-shape check; idp-connector's separate AUTH_JWKS_URL outage + startup check + the manifest-vs-config test in `internal/config/manifest_test.go`): I've already independently confirmed via `go build`/`go test` that cmd/api-service, cmd/idp-connector, and internal/config all build and pass, and that manifest_test.go really does parse k8s Deployment YAML and check env vars. Your job is to confirm the CI-service-container fix (check `.github/workflows/pr-check.yml` or equivalent for real Postgres/CockroachDB service containers) and the 1-replica/Recreate strategy claim (check the relevant Deployment manifests under `deploy/` for `replicas: 1` and `strategy: {type: Recreate}` on api-service and api-service-issuer).\n\n5. **Package layout claim**: confirm `cmd/api-service` and `cmd/idp-connector` really are thin (just main()/arg-parsing) and that `internal/app`/`internal/config` hold the shared logic, per the README's package-layout paragraph.\n\nReport back: for each of the 5 areas, PASS or a specific, precise discrepancy (quote the README claim and the actual file content that contradicts it). Do not just say \"looks fine\" — cite line numbers/file paths for anything you confirm or flag. Keep total report under 500 words."

But Wesley's cold read (no other project context, exactly the bar criterion 1 sets — \"a cold reader can tell what runs vs. what's a stub without asking\") found real gaps: several places where he'd have to ask someone rather than act. Fixes needed before I can send PASS:\n\n1. **Undefined/ambiguous mechanism names** — the doc uses \"touch counter,\" \"masked-vs-full-read scoping,\" and \"grant limiter\" without ever defining them, and separately names a \"failure-ratio rate limiter\" (Q3) and a \"10 req/min cap\" (finding 2) without saying whether these are the same mechanism as \"grant limiter\" or different ones. A reader can't tell how many distinct rate-limiting mechanisms this project actually has. Please either define each on first use (one clause each) or explicitly state which ones are the same thing under different names in different sections.\n\n2. **Verification claims with no reproduction path** — \"Verified live at...\", \"Verified in-cluster via kubectl port-forward\" (no namespace/service/port given), \"runs tests against real Postgres/CockroachDB service containers\" (no indication whether `go test ./...` alone reproduces this or a docker-compose step is needed first) — none are reproducible as written. Doesn't need a full runbook, but each should point to where the actual command/manifest lives (e.g. \"see deploy/api-service.yaml\" or \"`go test ./internal/dao/conformance/...` against `TEST_POSTGRES_DSN`\").\n\n3. **\"applied as a documented runbook step\" for demo data** — link the runbook, or the claim is unverifiable as stated.\n\n4. **`StopgapAuthorizer` scope unclear** — \"default-deny stand-in\" doesn't say whether it denies every request at that hook or only specific object-level checks. One sentence would close this.\n\n5. **Two of the four numbered findings** (issuer/verifier fix, connector JWKS fix) don't say where the startup-check logic actually lives — add the file (`cmd/api-service/main.go`, `cmd/idp-connector/main.go` per what I verified directly) so a reader could go check it themselves, matching the specificity the other two findings already have.\n\nEverything else — the four numbered findings themselves, the stub/real split, the AI-tooling note — Wesley called out as the strongest part of the doc and Desmond found no factual issues anywhere. This is a legibility pass, not a rewrite; should be quick. Ping me when it's updated and I'll do a final read before sending PM the PASS.",

Fixes needed before I can send PASS:\n\n1. **Undefined/ambiguous mechanism names** — the doc uses \"touch counter,\" \"masked-vs-full-read scoping,\" and \"grant limiter\" without ever defining them, and separately names a \"failure-ratio rate limiter\" (Q3) and a \"10 req/min cap\" (finding 2) without saying whether these are the same mechanism as \"grant limiter\" or different ones. Please either define each on first use (one clause each) or explicitly state which ones are the same thing under different names in different sections.\n\n2. **Verification claims with no reproduction path** — \"Verified live at...\", \"Verified in-cluster via kubectl port-forward\" (no namespace/service/port given), \"runs tests against real Postgres/CockroachDB service containers\" (no indication whether `go test ./...` alone reproduces this or a docker-compose step is needed first) — none are reproducible as written. Each should point to where the actual command/manifest lives (e.g. \"see deploy/api-service.yaml\" or \"`go test ./internal/dao/conformance/...` against `TEST_POSTGRES_DSN`\").\n\n3. **\"applied as a documented runbook step\" for demo data** — link the runbook, or the claim is unverifiable as stated.\n\n4. **`StopgapAuthorizer` scope unclear** — \"default-deny stand-in\" doesn't say whether it denies every request at that hook or only specific object-level checks. One sentence would close this.\n\n5. **Two of the four numbered findings** (issuer/verifier fix, connector JWKS fix) don't say where the startup-check logic actually lives — add the file (`cmd/api-service/main.go`, `cmd/idp-connector/main.go`) so a reader could go check it themselves, matching the specificity the other two findings already have.\n\nEverything else — the four numbered findings themselves, the stub/real split, the AI-tooling note — Wesley called out as the strongest part of the doc, and Desmond found no factual issues anywhere. This is a legibility pass, not a rewrite. Ping me when updated and I'll do a final read before sending the PM PASS. LT-43 stays In Test until then.",

1	# Track 03: Engineering & Delivery
2	
3	Go implementation of all three assignment questions — the DAO layer (Q1), the REST search/retrieve API with authentication (Q2), and the third-party identity connector (Q3) — plus the glue between Q2 and Q3. See root `../CLAUDE.md` for the full assignment text and how this track fits the other four; this file covers only what this track built, what's stubbed, and how.
4	
5	## What's implemented — live, deployed, verified against the running system
6	
7	- **Q1 — DAO layer** (`internal/dao`, `internal/dao/postgres`, `internal/dao/sqlite`): `user_profile`/`user_credential` storage behind one `Repository` interface, real implementations for Postgres/CockroachDB and SQLite. Verified against the actually-deployed Postgres database, and in CI against real Postgres and CockroachDB service containers — `.github/workflows/pr-check.yml`'s `build-lint-test` job sets `TEST_POSTGRES_DSN`/`TEST_COCKROACHDB_DSN` and runs `go test ./...` against them directly; reproduce locally by setting those two env vars to a running Postgres/CockroachDB instance and running the same command (no docker-compose step of this repo's own — `pr-check.yml` uses GitHub Actions service containers). A cross-backend conformance suite (`internal/dao/conformance`, LT-38) asserts all three backends behave identically, not just that their Go signatures match.
8	- **Q2 — REST API** (`internal/api`, `internal/app`): `POST /profiles/search`, `GET /profiles/{id}`, and a real RFC 6749 client-credentials `POST /auth/token` grant, all behind RS256 JWT verification. Verified live at `https://loginid-takehome.uplifttech.org` with real minted tokens; the exact commands run are the PO review scripts in `refinement/LT-39.md`/`LT-40.md`/`LT-51.md`. Three distinct in-process controls, easy to conflate by name, so defined separately here: `internal/api.RateLimiter` (a per-minute cap per client credential — 60 req/min for read scopes, 10 req/min for search); `internal/api.TouchCounter` (a separate, 24-hour cumulative distinct-record-touch cap per client, aimed at slow enumeration rather than bursts); `internal/api.GrantLimiter` (backoff on repeated failed `/auth/token` grant attempts, keyed by client+source IP — a different mechanism from the two above, and also reused as-is by the connector, see Q3 below). All three are exercised live in the PO review scripts above.
9	- **Q3 — connector** (`internal/connector`, `cmd/idp-connector`): the third-party IDP connector's own inbound `/auth`/`/identity` contract. Verified in-cluster via `kubectl -n loginid-takehome port-forward svc/idp-connector 8081:443` with a real vendor stub backing it (`refinement/LT-41.md`'s own PO review script has the full command sequence) — happy path, audience rejection, fail-closed identical-content error responses, a timing floor on the three internal failure branches, and a second rate-limit dimension specific to this connector (`internal/connector.identityRateLimiter`, keyed by *which identity* was attempted, not just which caller — distinct from `api.GrantLimiter` above, which the connector also reuses for its caller+IP dimension) actually firing under a live failed-auth burst, not just asserted in a unit test.
10	- **api-service → idp-connector integration** (`internal/onboarding`, LT-33): api-service's own outbound call to the connector, closing the loop between Q2 and Q3 — its own cached, refreshed OAuth2 client-credentials token; bounded timeouts and retry-with-backoff on connector calls; a generic upward failure on any connector-unreachable condition, with own-token-acquisition failures logged as a distinct class.
11	- CI/CD, containerization, secrets delivery, and database provisioning (04's stories, LT-45/46/47/52) are all Done and live — `pr-check` runs this track's tests against real Postgres and CockroachDB service containers on every PR, not just SQLite.
12	
13	## Deliberately stubbed — stated plainly, not left to infer
14	
15	- **The third-party vendor (ABC/XYZ) is an in-process `StubVendorClient`**, not a real HTTP integration. `idp-connector` falls back to it whenever `IDP_ABC_BASE_URL` is unset, and says so explicitly on startup. The assignment names the vendor generically — a real integration was never in scope (`refinement/LT-41.md`'s own stated non-goal).
16	- **The `authorize()` object-level policy hook is a `StopgapAuthorizer`** (`internal/api/stopgap_authorizer.go`), a hard-coded, default-deny stand-in — not the real caller-referral datastore `../02-ai-security-architecture/handoff-03-auth.md`'s own design describes. Scope is narrow and stated in its own doc comment: it only gates `profile:read:own`'s referral-membership check (a hard-coded `sub → allowed record id` map, currently just the one seeded QA client); `profile:read:any` is authorized entirely upstream of it (a valid `reason_code`, checked in the handler before this hook ever runs), and `profile:search` has no per-record target for it to gate at all — both of those paths return `true` unconditionally here, not because the check is real, but because this stand-in has no real `caller_referral` data to consult for them. A stated seam, not a hidden gap.
17	- **CockroachDB and SQLite are exercised in CI only, never deployed live.** Only Postgres runs in the actual cluster (LT-52's explicit scope limit) — don't go looking for a running CockroachDB instance anywhere.
18	- **No `POST /profiles` write endpoint exists or is planned.** Q2 is search/retrieve by the assignment's own text; a write path was ruled out as scope creep. Review/demo data enters via a version-controlled, idempotent SQL file (`deploy/demo-data/review-profiles.sql`), applied under the database's `migrator` role as a runbook step documented in `refinement/LT-51.md` (item 9(a) of its joint review script), never through the API.
19	- **`RateLimiter`, `TouchCounter`, and `GrantLimiter`** (all three defined above, under Q2) **are in-process and single-replica-only.** Their own code comments say a shared store (Redis) would be needed for a genuine multi-instance deployment — this project runs `api-service`/`api-service-issuer` at 1 replica with a `Recreate` rollout strategy *specifically* so this simplification holds correctly rather than silently degrading under a rolling update. That constraint exists because of a real bug this project found live (see below), not as a hypothetical caveat.
20	- **The retention sweep (LT-44) is designed and enforced at the schema/DAO level, but not yet operationally running.** `DeleteExpired`/`DeleteProfile` exist on the DAO composite and are tested there directly; nothing yet schedules or calls them against the live database. `../05-data-ops/pii-governance.md`'s retention policy is a real, tracked, backlogged story, not an abandoned requirement.
21	
22	## Package layout
23	
24	`cmd/api-service` and `cmd/idp-connector` are both thin wrappers — argument parsing and `main()` only. Route registration and config loading live once, in `internal/app` and `internal/config`, shared by both binaries rather than duplicated per binary (see `decisions/go-layout-debate.md` below). `internal/api` holds Q2's HTTP handlers, JWT middleware, rate limiting, and the token issuer; `internal/connector` holds Q3's inbound handlers and outbound vendor client; `internal/onboarding` holds LT-33's mediating client from `api-service` to the connector; `internal/dao` and its `postgres`/`sqlite` subpackages hold Q1, behind one `Repository` interface `internal/dao/conformance` tests identically across backends.
25	
26	## Test strategy
27	
28	Unit-heavy; integration deliberately stubbed where the assignment itself doesn't require full end-to-end coverage. Hand-written interface fakes, not generated mocks, for DAO/handler tests (`decisions/test-double-strategy.md`) — small enough interfaces that a fake struct per test case beats adopting a codegen dependency at this project's scale. The rule that any change to `dao.Repository` (or its sub-interfaces) updates its hand-written fake in the same PR is now a literal checklist line in `.github/pull_request_template.md`, not just prose in a design doc — LT-42's own review found the design doc alone insufficient (a PR landed an interface change without updating its fake, caught only in a later pass), so the checklist line is the actual enforcement site now, and the design doc explains why. Real-backend correctness (Postgres/CockroachDB/SQLite conformance, the CockroachDB serialization-retry path) is proven against real databases, in CI, not mocked — `internal/dao/conformance`'s own suite is the one enforcement site for "do the backends behave alike," distinct from a signature-matching test that proves nothing about behavior.
29	
30	## AI tooling and workflow
31	
32	Every implementation story in this track's backlog runs at `sonnet, high` except the connector (`idp-connector`'s `/auth`/`/identity`, Q3), which runs at `opus, high` — the one seat above sonnet in this track, per `../02-ai-security-architecture/planning-approach.md`'s connector-token-lifecycle exception: a subtle bug in that specific code path (a leaked or misscoped vendor token) directly contradicts this project's own threat model in a way most of this track's other code doesn't.
33	
34	Beyond model selection, implementation decisions in this track ran through structured adversarial review rather than being decided unilaterally:
35	- `decisions/go-layout-debate.md` — a three-hats debate (optimist/pessimist/pragmatist) on one binary vs. two, ruling to keep two binaries (already published and built against by 04) but merge the *authoring* cost via a shared `internal/app` package, plus a concrete requirement (bounded timeouts, no tight-looping retries on outbound calls) adopted from the pessimist's production-incident pattern-matching.
36	- `decisions/error-semantics.md` — a rotating devil's-advocate pass (Oren Castellan) that closed the sentinel-error set, forced a translation boundary so wrapped DB errors never leak driver text to an API client, and added explicit handling for `context.DeadlineExceeded`/`Canceled`.
37	- `decisions/context-propagation.md` — a second rotating devil's-advocate pass (Nolan Reyes, drawing on production-incident pattern-matching) that scoped multi-statement writes to a transaction under context cancellation, and named which write paths deliberately detach from the inbound context for durability.
38	- `decisions/test-double-strategy.md` — a third rotating devil's-advocate pass (Marisol Ferran) that weighed hand-written fakes against generated mocks; hand-written fakes stood, with the interface-drift risk closed procedurally (the PR-template checklist line above), not by adopting a codegen tool.
39	
40	This project is also a broader org-orchestration exercise — a PM agent coordinating five track leads, each running a small hired sub-team with deliberately varied personalities, using patterns like adversarial pairs, red/blue, and structured written debate (`../PLAN.md`, `../CASTING.md`) — the four decisions above are this track's own instance of that same structure, not a separate practice invented for engineering work alone.
41	
42	## Real, live-tested findings
43	
44	This track's own delivery process included live acceptance review against the actually-deployed system, not only code review and unit tests — and that process found and helped fix four real, distinct production-shaped bugs, each named individually rather than lumped together:
45	
46	1. **A CI coverage gap**, where `pr-check` silently *skipped* every Postgres and CockroachDB conformance test — only SQLite genuinely ran — while still reporting an overall green build. Fixed two ways: real Postgres/CockroachDB service containers added to the CI job, and every affected test fixture changed to fail loudly (not skip) when a required backend DSN is absent specifically in CI.
47	2. **A cross-replica rate-limiting bug** in `internal/api.RateLimiter` (the per-minute cap defined above under Q2, NOT `GrantLimiter` or `TouchCounter`), reproduced by actually crossing its 10 req/min search cap live against 2 running replicas — each replica's in-process limiter had no visibility into the other's request count, so the effective cap was silently doubled, and inconsistently (the exact overshoot depended on the load balancer's own distribution across pods). Fixed by moving `api-service`/`api-service-issuer` to a single replica with a `Recreate` rollout strategy (04's story), a deliberate scope limit stated plainly above, not a silent workaround. See `refinement/LT-39.md` for the full reproduction (both the pre-fix live burst test and the deterministic post-fix re-run).
48	3. **`api-service`'s own Q2 token issuer/verifier wiring shipped with `AUTH_JWT_ISSUER`/`AUTH_JWT_AUDIENCE` unset** in its Kubernetes manifest — minted tokens carried no `iss` and were checked against an empty `aud`, "verifying" successfully for the wrong reason rather than failing loudly. Fixed in the manifest, plus a startup check in `cmd/api-service/main.go` (`validateAuthConfig`) that now refuses to start with either unset, and a URL-shape check (`internal/config.ValidateEnvVarValue`) on the JWKS/issuer values specifically (a non-empty but garbage value is caught too, not just an absent one).
49	4. **A separate, later total outage in `idp-connector`'s (Q3's) own inbound auth** — its Deployment manifest never set `AUTH_JWKS_URL` at all, so every request, including a genuinely valid token, failed identically with a JWKS-fetch error. Distinct from finding 3: a different service, a different missing variable, found in a separate in-cluster review pass. Fixed the same way: the manifest, plus a startup check in `cmd/idp-connector/main.go` (`validateAuthConfig`), plus a systemic test (`internal/config/manifest_test.go`) that now parses every real Kubernetes Deployment manifest and asserts it sets everything its own mode requires — closing this specific class of gap structurally, in CI, rather than relying on a fourth live incident to catch the next occurrence.
50	
51	Naming these precisely — which subsystem, which variable, which fix — is itself part of what this AI-workflow note is meant to demonstrate: verification against the live, deployed system, not only against a test suite or a design doc.

// Ruled by Marcus Ilori (02), in response to a direct question before

// map for the seeded QA client credential (LT-51) — enough to
// demonstrate both the allow and deny paths of read:own's referral check
// in the live review, without ever allowing an arbitrary caller through.
//
// This only affects ScopeReadOwn's referral-membership check.
// ScopeReadAny's authorization is "has a valid reason_code," already
// checked in the handler before Authorize() is ever called; ScopeSearch
// has no per-record target for this Authorizer to gate at all. Both
// return true unconditionally here — there is no real caller_referral
// data this stopgap could consult for a real decision on those scopes
// either way, so denying them would not be more correct, only

Ran the review as designed: Desmond's claims check plus Wesley Okonkwo's (04, on loan) cold no-context read against criterion 1's own bar.\n\n**Desmond's claims check (against 541235c):** clean across all five areas checked directly in `/tmp/lt34review` — model/effort counts (`backlog.md`: 11× `sonnet, high`, exactly 1× `opus, high`, the connector), all four `decisions/*.md` summaries, the PR-template checklist line, the CI real-service-container claim (`pr-check.yml`), the 1-replica/`Recreate` claim (both `deploy/api-service.yaml` and `deploy/manifests.yaml`), and the thin-`cmd/`-package-layout claim. No discrepancies found.\n\n**Wesley's cold read (against 541235c):** found real gaps against criterion 1's own bar — a cold reader had to ask rather than act in several places: undefined/ambiguous mechanism names (`touch counter`, `masked-vs-full-read scoping`, `grant limiter` vs. `failure-ratio rate limiter` vs. `10 req/min cap` — couldn't tell how many distinct rate-limiting mechanisms actually exist), verification claims with no reproduction path (live URL, port-forward with no namespace/port, CI claims with no local-repro indication), an unlinked runbook reference for demo data, `StopgapAuthorizer`'s deny-scope left unstated, and two of the four numbered findings missing the code location the other two had. Sent to Renata as five concrete fixes; correctly flagged as legibility, not correctness — Desmond's parallel pass had already confirmed no factual errors.\n\n**Fix verification (against d3474c2):** read the updated README directly and independently confirmed each fix against source, not just against Renata's description:\n- The four rate/touch-limit mechanisms are now named and disambiguated on first use (`internal/api.RateLimiter`, `internal/api.TouchCounter`, `internal/api.GrantLimiter`, `internal/connector.identityRateLimiter`) — confirmed all four types actually exist at the cited files (`internal/api/ratelimit.go`, `touchcounter.go`, `grantlimiter.go`, `internal/connector/identitylimiter.go`).\n- CI/Q2/Q3 verification claims now each cite a concrete reproduction path (env vars + `go test` for Q1's CI job, the PO review scripts for Q2, the literal `kubectl -n loginid-takehome port-forward svc/idp-connector 8081:443` command for Q3).\n- Demo-data path corrected to the real filename (`deploy/demo-data/review-profiles.sql` — confirmed present, no `001-` prefix) and now cites the actual runbook step (`refinement/LT-51.md` item 9(a)).\n- `StopgapAuthorizer`'s scope is now precisely stated and matches the code exactly: read `internal/api/stopgap_authorizer.go` directly — it gates only `ScopeReadOwn`'s referral map; `ScopeReadAny`/`ScopeSearch` both return `true` unconditionally, for the stated reason (no real `caller_referral` data to consult either way, and `ScopeReadAny` is already gated upstream by `reason_code`). README's description matches this exactly, including which scopes return true and why.\n- Findings 3 and 4 now name real functions I confirmed exist: `validateAuthConfig` in both `cmd/api-service/main.go:69` and `cmd/idp-connector/main.go:29`, `config.ValidateEnvVarValue` at `internal/config/config.go:349`, and `internal/config/manifest_test.go` (confirmed in an earlier pass to genuinely parse Deployment YAML).\n\n**Verdict: PASSES.** LT-43: Done.\n\n---\nWork-By: Naomi Voss (PO, refinement + acceptance review); Desmond Okafor (claims check, twice — refinement draft and final PR); Tobias Lindqvist (subsystem-attribution objection on refinement draft); Wesley Okonkwo (04, cold-read pass on the merged PR); Renata Cole (03, README authorship + legibility fixes)."

9	## 1. Kubernetes auth — already enabled, no change needed
10	
11	`auth/kubernetes` was already mounted and correctly configured for **this** cluster: `kubernetes_host = https://192.168.0.44:6443` (uplift-kub-ctrl-plane-1), `token_reviewer_jwt_set = true`, `disable_iss_validation = true`. I enabled nothing and re-configured nothing.
12	
13	## 2–3. KV mount and the copy
14	
15	**Mount `secret/`** — pre-existing and already KV **v2** (`options.version=2`), so I did not enable a new one. Prefix **`secret/loginid-takehome/`** (it joins existing `fmn/` and `mail/`).
16	
17	All six copied, key names preserved exactly, each at version 1:
18	
19	| Vault path | keys |
20	|---|---|
21	| `secret/loginid-takehome/db-runtime-credential` | `dsn`, `password` |
22	| `secret/loginid-takehome/db-migrator-credential` | `dsn`, `password` |
23	| `secret/loginid-takehome/issuer-db-runtime-credential` | `dsn`, `password` |
24	| `secret/loginid-takehome/issuer-db-migrator-credential` | `dsn`, `password` |
25	| `secret/loginid-takehome/api-service-jwt-signing-key` | `signing-key` |
26	| `secret/loginid-takehome/postgres-superuser` | `password` |
27	
28	Verified by SHA-256 per key, source vs. read-back — all identical. `postgres-server-tls`, `loginid-takehome-tls`, `qa-client-credential` untouched. **The Kubernetes Secrets were copied, not deleted** — nothing is removed until Theo's side is live and you say so.
29	
30	## 4–5. Policies and roles
31	
32	Five policies, `read` only, on exact `secret/data/loginid-takehome/<name>` paths; five `auth/kubernetes` roles of the same names, `token_ttl=1h`, `token_max_ttl=4h`, namespace `loginid-takehome`.
33	
34	| Role / policy name | bound ServiceAccount | read paths |
35	|---|---|---|
36	| `loginid-takehome-api-service` | `api-service` | db-runtime-credential, connector-client-credential |
37	| `loginid-takehome-api-service-issuer` | `api-service-issuer` | issuer-db-runtime-credential, api-service-jwt-signing-key |
38	| `loginid-takehome-db-migrate` | **`db-migrate`** | db-migrator-credential, issuer-db-migrator-credential |
39	| `loginid-takehome-postgres` | **`postgres`** | postgres-superuser + all four db credentials |
40	| `loginid-takehome-idp-connector` | **`idp-connector`** | none (policy exists, grants nothing) |
41	
42	`connector-client-credential` returns **404, not 403** for api-service — permitted by policy, just not populated yet. LT-33 can write it with no Vault change.
43	
44	## ⚠️ The blocker: three workloads have no ServiceAccount
45	
46	Your brief assumed each workload had its own `serviceAccountName`. It doesn't. Across the entire repo only `api-service` and `api-service-issuer` are defined. **`postgres` (StatefulSet), `db-migrate` (Job), and `idp-connector` (Deployment) declare no `serviceAccountName` and run as `default`** — confirmed against both the repo manifests and the live pods after Theo's 17:15Z redeploy.
47	
48	I did not bind three roles to `default`. Doing so would mean any pod on the `default` SA could assume **any** of those roles — `idp-connector`, which you ruled gets nothing, could have assumed `loginid-takehome-postgres` and read `postgres-superuser`. That would have inverted the least-privilege requirement while appearing to satisfy it.
49	
50	Instead I created dedicated ServiceAccounts `postgres`, `db-migrate`, `idp-connector` in the namespace and bound the roles to those. They're inert until used. Verified: `default` is denied all five roles (403), `idp-connector` cannot assume the postgres role (403), and the same SA name in another namespace is denied (403).
51	
52	**So Theo must add `serviceAccountName: postgres` / `db-migrate` / `idp-connector` to those three workloads.** Until he does, those three cannot authenticate to Vault at all — this is a hard failure, not a degradation. Ideally the SA objects go into `manifests.yaml` too so it's declarative; his `loginid-takehome-deployer` Role already has `serviceaccounts` create/update.
53	
54	## 6. Vault address for the injector
55	
56	**`https://vault.vault.svc:8200`** — note **https**, not the `http://` in your brief. The listener has `tls_disable = 0`. Theo does **not** need to set an address annotation: that exact value is already the injector's built-in default (`AGENT_INJECT_VAULT_ADDR`).
57	
58	For TLS, two options:
59	- **House pattern** (what ns `mail` uses): `vault.hashicorp.com/tls-skip-verify: "true"`.
60	- **Proper verification**: I staged Secret **`vault-ca-cert`** (key `ca.crt`) into `loginid-takehome`, fingerprint-identical to the one in ns `vault`. Mount via `vault.hashicorp.com/agent-extra-secret: "vault-ca-cert"` + `vault.hashicorp.com/ca-cert`. The cert's SANs include `vault.vault.svc`, so this validates cleanly.
61	
62	**Flag:** that CA expires **2026-12-14**, about three months out. Not urgent, not mine to renew unilaterally, but it shouldn't be a surprise.
63	
64	## End-to-end proof, and one trap for Theo
65	
66	I ran a throwaway pod through the real injector on the `api-service` SA and deleted it afterwards. Full chain works: SA → k8s auth → role → policy → KV v2 → agent → file.
67	
68	It also caught something worth having: the obvious multi-line template renders a **trailing newline** into the file — 49 bytes for a 48-byte password. A `\n` on a DB password fails auth looking exactly like a wrong password. The single-line form produces an exact byte match, and I verified this rather than just recommending it:
69	
70	```
71	'{{- with secret "secret/data/loginid-takehome/db-runtime-credential" -}}{{ .Data.data.password }}{{- end -}}'
72	```
73	
74	## What I changed beyond the brief
75	
76	- Created ServiceAccounts `postgres`, `db-migrate`, `idp-connector` (reason above).
77	- Created Secret `vault-ca-cert` in `loginid-takehome`.
78	- Nothing enabled, nothing deleted, no existing Vault policy or role touched. The four `db-*`/`issuer-*` credentials, the JWT key, and the superuser remain live as Kubernetes Secrets.
79	
80	No secret value, token, or key appears above or in any file I wrote; the local Vault token cache was shredded and the port-forward is closed.
81	
82	---
83	
84	## The request Amber answered (summary)
85	
86	Copy six named Kubernetes Secrets from `loginid-takehome` into KV v2 at `secret/loginid-takehome/<secret-name>` preserving key names; create five read-only policies and five Kubernetes-auth roles (`loginid-takehome-{api-service, api-service-issuer, db-migrate, postgres, idp-connector}`) bound to the matching ServiceAccounts in the namespace, `token_ttl=1h`, `token_max_ttl=4h`; report names only. Leave `postgres-server-tls`, `loginid-takehome-tls`, and `qa-client-credential` as Kubernetes Secrets by ruling (`../02-ai-security-architecture/handoff-04-secrets.md` v3.1).
87	
88	## PM notes for the receivers
89	
90	- **Theo:** the three `serviceAccountName` additions (`postgres`, `db-migrate`, `idp-connector`) are a hard prerequisite; add the ServiceAccount objects to `deploy/manifests.yaml` so they are declarative. Use the single-line template form Amber verified (trailing-newline trap). Prefer the `vault-ca-cert` verification path over `tls-skip-verify`; the CA expiry (2026-12-14) is Warren's platform item, recorded in `teardown.md`'s neighbourhood, not this project's.
91	- **Helena:** five roles; `loginid-takehome-postgres` is the widest. Amber's denial matrix (default SA denied all five, idp-connector denied postgres, same SA name in another namespace denied) is the evidence to re-run, not re-derive.
92	- **Deletion of the six Kubernetes Secrets** happens only after Theo's PR is deployed and Naomi's live review passes, on the PM's word, via runbook.

85:## Story 5 — Observability: logging, metrics, never-log enforcement, retention-sweep alerting (LT-49)
86-
87-**Description:** Implement `./observability.md`: structured `slog` logging with an explicit-field discipline (never a whole request/response struct through a log call), a lint check flagging never-log-list field names, RED metrics with no PII-cardinality labels, ingress-level query-string redaction for search endpoints, RBAC-separated audit-log read access, and 05's S5 retention-sweep requirement — rows-examined/rows-deleted/oldest-surviving-row-age metrics per data class, with an alert when oldest-row-age exceeds retention-window-plus-sweep-interval, since a dead sweep job produces zero rows-deleted either way and gives no other symptom.
88-
89-**Acceptance criteria:**
90-- [ ] 02 confirms the never-log list (`handoff-04-secrets.md`'s nine items) is fully covered by a named enforcement site, not just a policy statement.
91-- [ ] No password, token, JWT, client secret, or DSN reaches a log call — enforcement site: explicit-field logging discipline plus the CI lint check.
92-- [ ] Search-endpoint name/phone query fragments never appear in ingress access logs — enforcement site: ingress log-format override / redaction.
93-- [ ] Audit-log read access is a distinct RBAC grant from Secret-read access — enforcement site: separate `Role` bound to an incident-review group.
94-- [ ] A stopped retention-sweep job triggers an alert within one sweep interval of its window being exceeded — enforcement site: the `oldest_surviving_row_age_seconds` alert rule, per data class.
95-
96-**Depends on:** 02 — `handoff-04-secrets.md`'s never-log list (final); 05 — `pii-governance.md` S5 retention numbers and data-class names (final).
97-
98-**Model/effort:** Sonnet, medium.
99-
100-**Type:** Story.
101-
102-**Labels:** `track-04`, `security-graded`, `no-code-yet`.
103-
104-## Story 6 — Configure log-sink retention for the audit trail (LT-20)
105-
106-**Description:** The consistency pass (`../decisions/cross-track-consistency.md`, "Deletion gap") ruled the enforcement site: a subject-deletion request reaches `user_profile`/`user_credential` by cascade but not application logs, metrics, or the audit trail, none of which has a `source` column or a deletion hook. 02's never-log list is the upstream control (PII values never enter a log in the first place, per `./observability.md`'s enforcement mechanism), which leaves exactly one remaining artifact needing a retention window: the audit trail itself (`sub`, scope, opaque record id, timestamp) — pseudonymous, not PII-free, and after a profile deletion the only remaining record that a given record id was looked up by a given caller. The enforcement site for its expiry is a retention policy on the log sink 04 already operates (Loki or equivalent, per `./observability.md`'s "Audit-log access" section) — not a deletion job, not a DAO method. 05 adds one row to `pii-governance.md`'s retention table for the audit-log window (basis: unknown, pending legal); 02 adds the two vocabulary/list fixes the pass identified for the never-log list (driver-error detail, `username`). This story configures the sink's retention setting to that window once it's a number.
107-
108-**Acceptance criteria:**
109-- [ ] The hand-off standard: 02 and 05 can each confirm their half (never-log list scope; retention-table row) without needing this story rewritten.
110-- [ ] The audit-log stream expires no later than 05's stated window — enforcement site: the log sink's retention configuration (a Loki `retention_period` or equivalent for the chosen sink), not application code.
111-- [ ] The retention configuration is separate from, and does not touch, any other log stream's retention or any Secret-access RBAC (`./secrets-delivery.md`) — enforcement site: sink-level retention is scoped per log stream/index, not global.
112-- [ ] Confirmed this is a configuration value, not a deletion job: no new DAO method, no new `cmd/` entrypoint, no scheduled job beyond what `./observability.md`'s retention-sweep story (Story 5) already covers for `user_profile`/`user_credential`-derived data.
113-
114-**Depends on:** 02 — never-log list additions (driver-error detail, `username`) confirmed; 05 — `pii-governance.md` audit-log retention-window row (basis: unknown, pending legal, per the pass).

}

1	# Observability + Never-Log Enforcement
2	
3	Design-only. Covers logging, metrics, and tracing for both services, and — the harder half — how `handoff-04-secrets.md`'s never-log list gets enforced as a mechanism, not just stated as a policy.
4	
5	## Logging
6	
7	Structured logging (`slog`, Go stdlib — no third-party logging library needed for two services this size), JSON output, one line per event. Every log line that touches a request carries `sub` (caller identity), the endpoint, status, and a request id — never the request or response body wholesale. This is the pattern the never-log list requires (hand-off item 8: "full request bodies of `POST /auth` and `POST /identity`... both contain items above by construction") — the enforcement mechanism is that handlers log a small, explicit field set assembled by hand, never `log.Printf("%+v", req)` or equivalent reflection-based dumps of a request/response struct. A struct that contains a password field can't leak through a log statement that never receives the struct.
8	
9	**Enforcement beyond "write it carefully":**
10	- A lint rule (a `golangci-lint` custom check, or a simple `go vet`-style grep in CI) that flags any log call passing a whole request/response struct, a `*http.Request` body, or any variable named/typed to match the never-log list's fields (`password`, `token`, `secret`, `dsn`, `client_secret`). Not foolproof — a determined developer can rename around it — but it catches the accidental case, which is the common one.
11	- Error-path discipline: wrapped errors are logged with `err.Error()` truncated/sanitized where the error type is known to carry sensitive detail (a DB driver error can echo the DSN; a vendor HTTP client error can echo the response body per hand-off item 4) — the wrapping layer strips those before the error reaches a log call, not the log call itself deciding case-by-case.
12	
13	## Metrics
14	
15	Standard RED metrics (rate, errors, duration) per endpoint, via Prometheus client library, scraped by whatever the lab cluster already runs (not stood up new for this take-home). Labels: method, route, status class — never a label with cardinality tied to user data (no `sub` or phone number as a metric label; that turns a metrics backend into an accidental PII store with no access control at all, which is a worse leak than a log line since metrics systems are typically more widely readable).
16	
17	## Tracing
18	
19	Not built out here — a two-service take-home with no running collector doesn't get more credible by naming OpenTelemetry. If ever added, it follows the same field discipline as logging.
20	
21	## The never-log list, operationalized
22	
23	Hand-off's nine items map to two enforcement surfaces, not nine separate mechanisms:
24	
25	1. **Application-level:** the structured-logging discipline above (explicit field sets, the lint check, error-wrapping sanitization) covers items 1, 2, 5, 6, 7 (password, tokens, JWTs, client secrets, DSN) — these never enter a Go `log`/`slog` call in the first place.
26	2. **Proxy/ingress-level:** item 9 ("search query parameters containing a name or phone fragment... redact or hash before any access log, including proxy and ingress logs 04 controls") is the one item application code can't fully own, since ingress access logs are written by the ingress controller, not the service. Mechanism: an ingress-level log-format override that logs the request path with query string stripped (or a regex redaction on the `phone`/`name` query params specifically) rather than the default full-URL access log format. This is a one-time ingress ConfigMap change, not a per-request code path.
27	3. Item 3 (PII field values from `/identity` or `user_profile`) and item 4 (raw vendor error bodies) are the same discipline as #1 applied to the connector specifically — the connector logs "called vendor X, got status Y," never the response body.
28	
29	## Audit-log access is a separate grant from Secret access
30	
31	Per the hand-off's Kubernetes-specific requirements: the log stream carrying `sub`/scope/record-id/timestamp (the "fact of access" the never-log list still permits) is itself sensitive enough to reconstruct who looked up whom, so it gets its own RBAC — a distinct, narrower `Role` bound to an incident-review group, separate from any ServiceAccount's `Secret`-read grant (`./secrets-delivery.md`). Mechanism: if logs go to a cluster-local sink (e.g., Loki), that sink's read API gets its own RBAC/auth in front of it, not the same one guarding `kubectl get secrets`; if logs go to an external platform, the equivalent is a scoped read-only role in that platform, provisioned separately from any cluster credential.
32	
33	## Retention-sweep observability (05's S5 requirement, final)
34	
35	Per `../05-data-ops/pii-governance.md`: the retention sweep must emit, per data class per run, three metrics — rows examined, rows deleted, and **the age of the oldest surviving row in that class**. An alert fires when that age exceeds the class's stated retention window plus one sweep interval. This is the one metric in this document tied to a specific reasoning worth repeating: a sweep job that silently stops running produces no error and no symptom on its own — "rows deleted" can't tell a broken sweep from a legitimately empty one, since both report zero. Oldest-surviving-row age is the one number that keeps climbing when the job is dead and holds steady when it's healthy, which is why it's the alerting signal, not just a nice-to-have metric alongside the other two.
36	
37	Mechanism: the sweep job (whatever invokes it — a CronJob against the lab cluster, per 05's mechanism-agnostic requirement) emits these as Prometheus metrics with a `class` label matching 05's actual retention classes — `source="direct"`, `source="idp_cache"`, and `idp_cache_orphan` for an orphaned `idp_cache` row (`../05-data-ops/pii-governance.md`), never a label carrying the PII itself, same discipline as the RED-metrics rule above. (An earlier draft of this section invented `vendor_token_cache`/`idp_identity_cache` as class names — those don't correspond to anything 05 tracks and described a connector token cache the S3 ruling never adopted; corrected here.) The alert rule is `oldest_surviving_row_age_seconds{class="X"} > (retention_window_seconds + sweep_interval_seconds)`, evaluated per class.
38	
39	**Batched sweeps: only a drained result feeds the metric.** 05's `DeleteExpired` is batched (a bounded `maxRows` per call, `SweepResult.Drained` marking the last batch of a sweep) — `OldestSurvivingAt` is meaningful only on a `Drained == true` result, since mid-sweep the oldest deletable row is still present by construction and would read as stale on every batch but the last. The sweep job emits `oldest_surviving_row_age_seconds` only from drained results, never from an intermediate batch; the alert rule above already only ever sees what's published, so this is a constraint on what the job emits, not an extra filter the alert needs to apply. Getting this wrong means the alert fires on every sweep and gets muted, which is worse than not having it.
40	
41	## Log-sink retention: the deletion-gap enforcement site
42	
43	Application logs, metrics, and traces have no `source` column, no clock tied to a `user_profile` row, and no key a subject-deletion request could reach by cascade — a deleted profile's data can still exist in a log line indefinitely. 05's never-log list (`handoff-04-secrets.md`) and this document's enforcement mechanism (above) are the upstream control — if PII never enters a log, there's nothing in a log to expire — but that only holds for the fields on the list. What's left (chiefly the audit trail: `sub`, scope, opaque record id, timestamp — permitted by design, pseudonymous rather than PII-free) still needs a retention window: `pii-governance.md` § "Retention windows (S5)", the "Audit-log stream" row (clock: the entry's own timestamp; window: proposed, pending a legal ruling; disposal: **expiry at the sink**) names this document's log-sink retention policy as its enforcement site — the citation resolves in both directions. Not a deletion job 04 writes — a retention setting on infrastructure 04 already operates.
44	
45	**Not the same object as the `deletion_log` table.** 05's `deletion_log` (rows written transactionally by `DeleteExpired`/`DeleteProfile`) is a separate thing from the audit-log stream above — it's PII-free by construction, carries no `RetentionClass`, and isn't in 05's retention table at all; nothing here applies to it, and no metric from a `SweepResult` does either. If a retention window is ever wanted for that table, it's a DAO contract change (05's to make), not a sink-retention config value (04's).
46	
47	## What's deliberately not here
48	
49	No SLOs/error-budget policy, no alerting-rule catalog beyond the retention-sweep alert above. A take-home needs the shape of an observability approach and a credible enforcement mechanism for the one hard requirement (never-log); it doesn't need a full SRE runbook.

1	# Hand-off 02 → 04: Secrets inventory and never-log list
2	
3	Status: **v3.1** — corrects v3's own reasoning on `postgres-superuser` (below): it does *not* stay a Kubernetes Secret after all, since the "bootstrap before Vault exists" argument doesn't hold once Vault is already running independently of Postgres — Theo's finding. Three named exceptions remain, not four. v3 (delivery mechanism changes from raw Kubernetes `Secret` mounts to **Vault Agent Injector, per-ServiceAccount Vault roles**, Warren's ruling, LT-46, 2026-09-13) and everything else are otherwise unchanged. v2's S7 objection turn, F12/F13/F15/F50 fixes still hold — this revision changes *delivery mechanism*, not the inventory or the never-log list. Receiver: Theo Bergman, `../04-infra-devops/`. Written to the project's hand-off standard: 04 should be able to act on this without re-deriving the reasoning in `threat-model.md`, `api-auth-design.md`, or `connector-security.md`.
4	
5	## Assumptions this hand-off makes
6	
7	1. Deployment target is 04's **real Kubernetes cluster, reachable via a plain nginx Ingress + cert-manager on the cluster's shared LoadBalancer** (DNS CNAME to `uplifttech.ddns.net`, public at `https://loginid-takehome.uplifttech.org` — no tunnel; Warren's implementation go-ahead, 2026-09-12, updated from a design-only reference). **Delivery mechanism (updated 2026-09-13, LT-46): the Vault Agent Injector, not raw Kubernetes `Secret` mounts, for every application-level secret in the inventory below** — a Vault Agent sidecar, added via pod annotation, authenticates to Vault using the pod's own Kubernetes ServiceAccount token (Vault's Kubernetes auth method) and renders each secret to a file on an in-memory (`emptyDir`, `medium: Memory`) volume shared with the application container; nothing application-level is written to a Kubernetes `Secret` object, and therefore nothing application-level reaches etcd's base64-not-encrypted-by-default storage at all — this closes the etcd requirement below by removing the object from etcd entirely, not by enabling etcd encryption at rest. Amber (Vault operator) provisions the KV paths, Vault policies, and Kubernetes-auth roles that make this work; names only are visible in any transcript, never values. Every requirement below is written so it still holds regardless of mechanism; this is the mechanism 04 actually builds to now. **The repository is now public** (`https://github.com/wtvamp/loginid-takehome`) — every requirement in this document that says "never in source or committed config" is now categorical, with no private-repo safety net.
8	
9	**`postgres-superuser` is Vault-delivered after all — v3's reasoning here was wrong, corrected rather than quietly patched over.** v3 argued a Vault Agent sidecar "doesn't help a database's own first-init bootstrap" because it's a pattern for pods already running and authenticating to Vault themselves. That's true of the *sidecar* pattern specifically, but conflates two different things: whether *Vault itself* exists yet (it does — an independent HA Vault, already running on this cluster, not something Postgres hosts or depends on existing) versus whether *this specific pod* has started yet. Vault Agent supports an **init-container** mode for exactly this shape of problem: it runs to completion *before* the main container starts, authenticates via the pod's own ServiceAccount token the same as the sidecar pattern, and renders the credential to a shared volume the main container then reads at its own startup — Postgres's official image already supports `POSTGRES_PASSWORD_FILE` (a file path) as an alternative to `POSTGRES_PASSWORD` (a literal value), so the init script reading from a Vault-rendered file instead of a `secretKeyRef` env var is a small, well-supported change, not a redesign. There was no actual chicken-and-egg here once Vault's own existence is independent of Postgres's — v3 treated "the database is bootstrapping" and "Vault needs bootstrapping" as the same problem when they aren't.
10	
11	**Postgres gets its own Vault role, `loginid-takehome-postgres`**, reading `postgres-superuser` plus the four existing DB-credential paths (`db-migrator-credential`, `db-runtime-credential`, `issuer-db-migrator-credential`, `issuer-db-runtime-credential`) — five paths, the widest of any role in this system, since the Postgres StatefulSet's init script is what seeds all of them. This is the role deserving the closest look in Helena's policy review, precisely because it's the widest.
12	
13	**Three named exceptions remain Kubernetes Secrets, not Vault-delivered:**
14	
15	- **`postgres-server-tls`** — cert-manager's own `Certificate`/`Secret` mechanism (`threat-model.md` Assumption 9), consumed directly by the Postgres StatefulSet's TLS startup args. cert-manager already *is* a secure, automated, rotation-aware delivery mechanism purpose-built for exactly this (a server needing a TLS keypair) — routing it through Vault instead would duplicate a solved problem, not close a gap.
16	- **`loginid-takehome-tls`** — same reasoning, one level up: the public Ingress's cert-manager-issued certificate, consumed by the Ingress controller directly. Same native, already-secure mechanism; no benefit to re-routing through Vault.
17	- **The ARC GitHub App auth credential** (in the runner namespace, not this application's namespace) — a platform/CI-infrastructure secret belonging to the runner controller itself, not to `api-service`/`idp-connector`/the issuer. It authenticates GitHub's App to provision self-hosted runners; it's outside this application's own trust boundary and namespace, and this hand-off's scope is this application's secrets, not the CI platform's own.
18	
19	The common thread across all three: each is either an already-native, already-secure Kubernetes-integrated mechanism (cert-manager) that Vault would only duplicate, or a platform-level secret outside this application's own namespace/trust boundary — not an ad hoc carve-out, and not "hasn't gotten to it yet."
20	
21	**A fourth item, `qa-client-credential`, is a different category from the three above and stays a Kubernetes Secret for a different reason (ruled 2026-09-13, jointly with Theo Bergman): it's an ops/review-tooling artifact, not an application secret, and structurally cannot use the Vault Agent Injector pattern at all.** The Vault Agent mechanism delivers a secret into a *running pod's filesystem at startup* — `qa-client-credential` is never consumed that way; its only consumption pattern is a human running `kubectl get secret qa-client-credential -o jsonpath=...` directly to manually mint a review token, with no pod in between. There's nothing to inject into. Moving it to Vault would only relocate where a human types a fetch command (`kubectl` → `vault` CLI); it wouldn't close any actual exposure, since the exposure surface either way is "whoever can authenticate as a cluster operator." **Least-privilege confirmation, not just deferred:** checked against `deploy/rbac.yaml` directly — the CI deployer's Role has no `secrets` verbs at all, and no application ServiceAccount (api-service, issuer, idp-connector) has any Secrets-API grant either, since Vault handles their application secrets now. `qa-client-credential`'s actual access boundary is therefore "human operators with direct cluster access," which is Assumption 7's existing operator trust boundary — not a new, unstated exposure this migration should have closed and didn't.
22	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.
23	3. An **external operator agent** — a human or automated actor outside this project, holding cluster-admin or namespace-admin rights on 04's real lab cluster, who applies Kubernetes manifests to it — is a privileged actor outside this service: anyone who can apply a manifest can read any Secret it mounts. Consequence for 04: manifests reference Secrets by name and never carry values; values are set out-of-band. This is a named trust boundary in `threat-model.md` Assumption 7, not a silent assumption; nothing further about who that operator is needs to be re-derived from 04's own files to act on this hand-off. As of this update, 04 has not yet made contact with that operator or deployed anything — `threat-model.md` carries the dated status.
24	4. **Updated 2026-09-12:** with Warren's implementation go-ahead, 04's build stories will deploy to and contact the operator of the real cluster named in Assumption 1 — this is no longer a hypothetical the document describes in the abstract. As of this update, that contact hasn't happened yet; `threat-model.md` Assumption 7 carries the current, dated status and gets updated the moment it changes.

26	## Secrets inventory
27	
28	| # | Secret | Used by | Injection requirement (02 sets it) | Rotation expectation | Delivery mechanism (04's, updated v3: Vault Agent unless named otherwise) | Never-log |
29	|---|---|---|---|---|---|---|
30	| 1 | Database credentials, carried inside `DB_DSN` | `api-service` | Runtime-injected; never in source, image, or committed config. **Required, not preferred: file mount via a `DB_DSN_FILE` convention** (03 to add alongside `DB_DSN`), because a DSN's embedded password is exposed by `kubectl describe`, crash dumps, and child-process environment exactly as much as any other secret in this table — there is no citation that makes `DB_DSN` a lesser case, so this track is not treating it as one | On credential rotation; service restart or reload acceptable | **Vault Agent sidecar**, rendered to the path `DB_DSN_FILE` reads, on an in-memory volume; `api-service`'s Vault role reads exactly this KV path and nothing else. Env-var `DB_DSN` remains a fallback only until 03 ships the file-based convention | Yes — the DSN contains the password; log the driver name and host at most |
31	| 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 | **Vault Agent sidecar, only on the issuer Deployment's pod spec** — the verifying Deployment's Vault role has no policy path granting this secret at all (least-privilege at the Vault-policy layer now, in addition to the pod-spec-absence and CI-deployer-Role controls below, which still hold independently of the delivery mechanism): (a) the verifying Deployment's pod spec contains no reference to this secret at all; (b) the CI deployer's Role has no `secrets` verbs on Kubernetes Secrets, and (new) no Vault policy grants it read on this KV path either; (c) provisioned into Vault out-of-band, never through the CI-managed manifest set | Yes |
32	| 3 | JWT **public** key / JWKS | `api-service` middleware | Not a secret; may ship in config or be fetched from the issuer | Follows #2 | Plain `ConfigMap` or fetched URL; listed here so 04 does not over-protect it — not secret, not Vault-delivered | No (but never log full tokens — see below) |
33	| 4 | API caller `client_secret`s (OAuth2 client-credentials) | Authorization server (verifies); callers hold their own copy | **Stored hashed** (Argon2id, same floor as `threat-model.md` Asset 1), never plaintext at rest; issued once at provisioning and not recoverable | Per-client rotation on demand; revoke by deleting the hash | Lives in the issuer's own Postgres database (`oauth_client` table), not a Kubernetes Secret or Vault KV path; 04 delivers only that database's own connection credential (Vault-delivered, same shape as row #1) | Yes |
34	| 5 | Connector's own vendor registration: `IDP_ABC_CLIENT_ID`, `IDP_ABC_CLIENT_SECRET` (and the XYZ pair if a second vendor is configured) | `idp-connector` | Runtime-injected; never in source or committed config; `client_id` is low-sensitivity but travels with the secret and gets the same handling | Per vendor's policy; expect manual rotation | **Vault Agent sidecar**, one KV path per vendor so rotating ABC never touches XYZ; `idp-connector`'s Vault role reads exactly its own vendor paths | Yes for the secret; keep the id out of logs too |
35	| 6 | Vendor `access_token` (returned by our own `/auth` to its authenticated caller, presented as a header on our own `/identity` — updated for F3's caller-holds-the-token model, seam re-run regression fix) | `api-service` holds it briefly between the two calls; `idp-connector` only ever sees it as a caller-presented header on a single `/identity` request, never fetches or holds it between calls itself | **Not a deployed secret** — transient on both sides, never cached, never persisted. Neither `api-service` nor `idp-connector` writes it to a datastore (S3's no-cache ruling, restated for the two-party model in `connector-security.md` §1) | Expires on its own; never persisted across restarts by either party | No `Secret` object and no Vault KV path anywhere in this flow — there is nothing here for 04 to provision | Yes — never, including error paths, on both sides of the exchange |
36	| 7 | Data-encryption key (KEK) for envelope encryption of any TOTP shared secrets | `api-service` (TOTP) only — **not a committed feature of this submission**; `user_credential.method` is modeled as an extensible lookup table (`../05-data-ops/multi-db-strategy.md`) that supports TOTP as a *possible* value, but no TOTP implementation is planned unless 03 builds one. **The vendor-token-cache use case for this row no longer exists**: S3's red/blue on the connector token lifecycle is closed (`decisions/connector-token-lifecycle-redblue.md`) — no cache by default, and the token is never held by the connector between calls at all under F3's model (row 6), so there is no vendor-token cache for a KEK to encrypt. This row is provisioned only if TOTP materializes — it is a contingency the inventory names in advance, not a live requirement for 04 to build now | Runtime-injected as a file; the KEK never leaves the process that decrypts | Rotation by re-wrapping DEKs; never requires re-hashing passwords (those are hashed, not encrypted) | If this row is ever provisioned: Vault's own Transit engine is a more natural fit than a static KEK on a KV path (Vault already does envelope encryption as a first-class feature) — 04's call if this materializes, the requirement is only that the key exists, is not in source, and isn't a plain KV secret if Transit is available | Yes |
37	| 7a | Credential to reach the external KMS, **only if 04 exercises a non-Vault-Transit KMS alternative in row #7** (a role, API key, or client cert — whichever the chosen KMS uses) | Whichever binary holds the KEK reference (#7) | Same discipline as every other row here: runtime-injected, never in source, never provisioned ad hoc outside this table | Per the KMS provider's own rotation mechanism | Cloud-KMS access is typically workload-identity-based (no static credential to store); if the chosen KMS instead requires a static credential, it's Vault-delivered the same as every other row, kept out of the CI deployer's access the same way row #2's is | Yes |
38	| 8 | TLS serving private keys for `api-service` and `idp-connector` | Ingress / each binary, per 04's termination choice | Runtime-injected; TLS 1.2+ only; certificate validation never disabled in any environment (`connector-security.md` §2) | Per certificate lifetime; automated issuance preferred | **Named exception, stays a Kubernetes `Secret` (`kubernetes.io/tls`), not Vault-delivered** — cert-manager's native mechanism, same reasoning as `loginid-takehome-tls`/`postgres-server-tls` above: Vault would only duplicate a problem cert-manager already solves | Yes |
39	| 9 | End-user's vendor password (`POST /auth` request body) | `idp-connector`, transient | Never persisted, never cached, held only for the vendor call | n/a | Nothing for 04 to deliver; listed so nobody creates a place for it | **Yes — under no circumstance, including stack traces** |
40	| 10 | `api-service`'s own client credential (`client_id`/`client_secret`) toward the issuer, scoped `connector:identity-lookup`/`aud: idp-connector-service` — required for `api-service` to call `idp-connector`'s own authenticated `/auth`/`/identity` (`connector-security.md` §5) | `api-service` (the Deployment serving question 2's API, acting as a caller of the connector on a user's behalf) | Runtime-injected; never in source or committed config — same discipline as row 5's vendor registration, added by the cross-track consistency pass (F15), which found this credential asserted as a requirement in `connector-security.md`/`handoff-03-auth.md` with no inventory row | Same per-client rotation as row 4 (revoke by deleting the issuer-side hash) | **Vault Agent sidecar**, `api-service`'s Vault role reads this path in addition to row #1's — the two are separate KV paths under the same role, not merged, so a policy review can still see them as distinct grants | Yes |
41	| 11 | Postgres bootstrap superuser credential (`postgres-superuser`), plus the four DB-credential paths the same init script seeds (`db-migrator-credential`, `db-runtime-credential`, `issuer-db-migrator-credential`, `issuer-db-runtime-credential`) | Postgres StatefulSet's `initdb` scripts, at first container init | `POSTGRES_PASSWORD_FILE` (file path, not a literal env var) for the superuser; the init script reads the other four the same way | Manual, rare (bootstrap-only credentials) | **Vault-delivered via init-container mode (corrected, v3.1) — not the sidecar pattern, and not a Kubernetes Secret.** A Vault Agent init container runs to completion before the main Postgres container starts, authenticates via the StatefulSet's own ServiceAccount, and renders all five paths to a shared volume the main container reads at its own startup. Dedicated role `loginid-takehome-postgres`, the widest role in this system (five paths) — the one deserving the closest look in policy review | Yes |

43	Names marked pending in 03's boundary: `AUTH_JWT_ISSUER` / `AUTH_JWT_AUDIENCE` are configuration, not secrets; this track will confirm their final values in `handoff-03-auth.md`. They are listed here only so 04 does not classify them as secrets.

  "file_path": "/Users/warrenthompson/Source/LoginID/04-infra-devops/refinement/LT-49.md",
  "content": "# LT-49 refinement — S5: observability (logging, metrics, never-log enforcement, retention-sweep alerting)\n\n**Product Owner:** Naomi Voss (01). **Research team:** Imogen Hale, Desmond Okafor, Tobias Lindqvist. **Engineering:** Theo Bergman (04, lint check, ingress redaction, RBAC, sink, alert rule), Renata Cole (03, metrics exposure at the sweep-invocation layer, never-log test at the application layer). **Design inputs:** Marcus Ilori (02, never-log-list completeness confirmation), Priya Nandakumar (05, retention-alert-threshold seat). **Source:** `04-infra-devops/backlog.md` Story 5 (LT-49), design already done in `04-infra-devops/observability.md`.\n\n**Who did the work:** Refined by Naomi Voss (PO).\n\n## Why this one, now\n\nPer team-lead: LT-44's sweep wiring (merged, #55) exists but its metrics have nowhere to land and no alert watches them — `oldest_surviving_row_age_seconds` is worthless as a dead-sweep detector if nothing scrapes or alerts on it. `observability.md` is fully designed already (this is a build story against an existing design, not a fresh design pass), so this is genuinely ready to refine now rather than re-litigated.\n\n## What this story actually is\n\nNot a redesign — `observability.md` already specifies every mechanism this story builds:\n1. **Logging discipline + lint check** (04): explicit-field `slog` logging, a CI lint rule flagging never-log-list field names/whole-struct log calls.\n2. **Ingress-level redaction** (04): search-endpoint `name`/`phone` query fragments never reach an ingress access log.\n3. **Audit-log RBAC** (04): a distinct `Role` for audit-log read access, separate from any Secret-read grant.\n4. **Retention-sweep metrics + alert** (03 exposes, 04 sinks/alerts): `rows_examined`, `rows_deleted`, `oldest_surviving_row_age_seconds{class}` per LT-44's sweep, only from `Drained == true` results (LT-44's own criterion, unaffected here — this story is the metrics *sink and alert rule*, not re-deriving the emission-gating logic LT-44 already built).\n5. **Never-log-list completeness confirmation** (02, Marcus): a sign-off that all 11 items in `handoff-04-secrets.md`'s list map to a named enforcement site, not just a policy statement — the mapping already exists in `observability.md`'s \"operationalized\" section; this is Marcus confirming it, not this story inventing new coverage.\n\nThis is genuinely two-track work, per team-lead's framing: 04 builds the sink, alert rule, ingress redaction, RBAC, and lint check; 03 adds/confirms the metrics-exposure code path at the sweep-invocation layer (LT-44's own code) and a never-log-list enforcement test at the application layer (the lint check's *complement* — a test asserting specific known-sensitive values never appear in captured log output, catching what a static lint rule can miss).\n\n## Acceptance criteria (restated from `backlog.md` S5, split by side)\n\n**04 side:**\n- [ ] The CI lint check (a `golangci-lint` custom rule or CI-run grep) flags any log call passing a whole request/response struct, an `*http.Request` body, or a variable named/typed to match the never-log list's field names (`password`, `token`, `secret`, `dsn`, `client_secret`) — enforcement site: the lint rule itself, run in CI, not a design-doc statement.\n- [ ] Ingress-level log-format override or redaction ensures `name`/`phone` query-string fragments on `POST /profiles/search` never appear in ingress access logs — enforcement site: the ingress `ConfigMap`'s log-format setting.\n- [ ] Audit-log read access (the log stream carrying `sub`/scope/record-id/timestamp) has its own RBAC `Role`, bound to an incident-review group, distinct from any ServiceAccount's Secret-read grant (LT-46's Vault roles or any residual Kubernetes Secret access) — enforcement site: the log sink's own RBAC/auth layer (Loki or equivalent), not reused from cluster Secret RBAC.\n- [ ] `rows_examined`, `rows_deleted`, `oldest_surviving_row_age_seconds{class=\"direct\"|\"idp_cache\"|\"idp_cache_orphan\"}` (LT-44's metrics, exposed via 03's code, per criterion below) reach a real Prometheus-compatible sink 04 already operates — enforcement site: the scrape config or push-gateway wiring, not just \"the metric exists in code.\"\n- [ ] The alert rule `oldest_surviving_row_age_seconds{class=\"X\"} > (retention_window_seconds + sweep_interval_seconds)` is configured per class in 04's actual alerting stack (not just theoretically derivable from the metric) — enforcement site: the alert-rule config file/CRD, with the real numeric retention windows (24 months/`direct`, 30 days/`idp_cache`, 7 days/`idp_cache_orphan`, per LT-44/`pii-governance.md`) and the real `sweep_interval_seconds` (the CronJob's own schedule, LT-44's manifest) substituted in, not left as placeholders.\n\n**03 side:**\n- [ ] LT-44's sweep-invocation code exposes `rows_examined`/`rows_deleted`/`oldest_surviving_row_age_seconds` as real Prometheus client-library metrics with the `class` label values above — confirming/completing LT-44's own metrics-emission code path (LT-44's refinement already required emission gated on `Drained == true`; this criterion is that the values reach an actual `prometheus.Client` registration, not just a `log.Printf` or an internal struct field).\n- [ ] A never-log-list enforcement **test** exists at the application layer — asserting that a representative sample of never-log-list values (a password, a token, a DSN, a raw vendor error body) passed through the real logging path never appears in captured log output — the lint check's complement, catching what a static grep-style rule can miss (e.g., a value passed through an intermediate variable the lint rule's pattern doesn't match). Enforcement site: a test in `internal/api`/`internal/connector` that captures `slog` output and asserts absence of seeded sensitive values.\n\n**02 side:**\n- [ ] Marcus (02) confirms in writing that `handoff-04-secrets.md`'s 11-item never-log list is fully covered by a named enforcement site (the mapping table in `observability.md`'s \"operationalized\" section, cross-checked item-by-item) — not a re-derivation, a confirmation that the existing mapping is actually complete.\n\n## Priya's seat — retention-alert threshold\n\n**Added per team-lead's routing:** Priya Nandakumar (05) has a seat specifically on whether the alert formula's two terms are the right ones, since she owns the retention-window numbers and the sweep-invocation cadence assumption. Question for her turn: does `retention_window_seconds + sweep_interval_seconds` need a third term — a slack/grace factor for a sweep run that's merely running slow (not dead), given LT-44's `concurrencyPolicy: Forbid` means a slow run causes the *next* scheduled run to be skipped rather than overlapped, which could itself push `oldest_surviving_row_age` past the naive threshold on a run that's behind schedule but not actually broken? Her ruling on whether the two-term formula from `observability.md` already accounts for this (worth checking: `observability.md`'s own text doesn't address the Forbid-causes-skip interaction) is this story's own genuinely open, not-yet-refined question — recorded here rather than assumed either way.\n\n## Non-goals\n\n- No new retention windows or data-class definitions — those are `pii-governance.md`'s numbers, already final per LT-44.\n- No tracing/OpenTelemetry — explicitly out per `observability.md`'s own \"what's deliberately not here.\"\n- No general SLO/error-budget policy or alert catalog beyond the one retention-sweep alert rule this story requires.\n- No re-derivation of the never-log list's 11 items or their categorization — that's `handoff-04-secrets.md`'s inventory, already final; this story only confirms and enforces it.\n\n## PO review script\n\n1. Read the CI lint-check config/rule directly; confirm it actually flags the named patterns (whole-struct log calls, never-log-list field names) rather than being a no-op placeholder.\n2. Confirm the ingress `ConfigMap`'s log-format override is applied to the live ingress (not just committed in a manifest never deployed) and that a live search request's `name`/`phone` query params don't appear in the ingress access log.\n3. Confirm the audit-log RBAC `Role` is genuinely distinct from Secret-read RBAC — read both role definitions, confirm no overlap, confirm the incident-review group binding.\n4. Confirm the three sweep metrics reach the real sink (query the sink directly for `oldest_surviving_row_age_seconds`, don't just trust the code emits it) and that the alert rule is configured with the real numeric retention windows and real sweep interval substituted in, not placeholders.\n5. Confirm 03's never-log-list enforcement test exists, runs in CI, and genuinely fails if a seeded sensitive value leaks into captured log output (mutate the test locally to confirm it can fail, not just that it currently passes).\n6. Confirm Marcus's never-log-list completeness confirmation is recorded, and read it against the 11-item list directly rather than trusting a summary.\n7. Confirm Priya's ruling on the alert-formula question above is recorded, and that the alert rule matches whatever she rules (two-term formula as-is, or a third grace term).\n8. Once deployed: deliberately stop the sweep `CronJob` (suspend it) and confirm the alert fires within one sweep interval of the retention window being exceeded — the one live-tested proof this story's core reasoning (\"a dead sweep produces no other symptom\") actually holds.\n"

  "prompt": "Naomi (PO) just drafted `04-infra-devops/refinement/LT-49.md` for story LT-49 (observability: logging, metrics, never-log enforcement, retention-sweep alerting). Read it, then claims-check it against its cited sources:\n\n1. `04-infra-devops/observability.md` — confirm every mechanism the refinement doc attributes to this design doc (lint check, ingress redaction, audit-log RBAC, the alert formula `oldest_surviving_row_age_seconds{class} > retention_window + sweep_interval`, the Drained-only emission gating, the 11-item-vs-\"operationalized\"-mapping claim) is actually stated there, not invented or misquoted.\n2. `02-ai-security-architecture/handoff-04-secrets.md`'s never-log list — count the items. The refinement doc says 11 items; verify that count and that items 10/11 (driver-error detail, username) are really in the list as the refinement doc describes.\n3. `03-engineering-delivery/refinement/LT-44.md` — confirm the refinement doc's claims about LT-44 (the three metric names, the class label values `direct`/`idp_cache`/`idp_cache_orphan`, the `Drained==true`-gating requirement, `concurrencyPolicy: Forbid`) match what LT-44.md actually says, since LT-49 builds directly on it.\n4. `04-infra-devops/backlog.md` Story 5 — confirm the acceptance criteria the refinement doc restates match the backlog's actual criteria (it should already match closely, but check for drift).\n\nReport PASS or specific discrepancies (quote the refinement doc's claim and the source text that contradicts it) for each of the 4 areas. Under 400 words."

  "prompt": "Naomi (PO) just drafted `04-infra-devops/refinement/LT-49.md` (observability: logging/metrics/never-log enforcement/retention-sweep alerting), splitting it into 04-side, 03-side, and 02-side criteria, plus a specific open question routed to Priya (05) about whether the alert formula `oldest_surviving_row_age_seconds{class} > retention_window + sweep_interval` needs a third grace term given LT-44's `concurrencyPolicy: Forbid` (a slow sweep run causes the next scheduled run to be *skipped*, not overlapped — could that make a merely-slow-but-healthy sweep look dead to the naive two-term alert?).\n\nRead the refinement doc, plus `04-infra-devops/observability.md` and `03-engineering-delivery/refinement/LT-44.md` for context. Your job: find the strongest real objection to how this refinement doc is scoped or worded — the standing pattern on this project has been catching real gaps (unenforced config, missing fail-loud behavior, concurrency races, mislabeled subsystems), not just style nits. Things worth checking:\n- Is the 03/04 split actually clean, or does something fall in a gap between \"03 exposes the metric\" and \"04 sinks/alerts it\" that neither side's criteria actually covers (e.g., who confirms the metric's numeric VALUE is correct, not just that it's exposed)?\n- Is the PO-review-script step 8 (\"suspend the CronJob and confirm the alert fires\") actually testable within one sweep interval, or does it silently assume a short interval that may not match whatever schedule 04 picks?\n- Does the never-log-list enforcement test (03 side) actually close a real gap the CI lint check (04 side) doesn't, or is it redundant work being asked of the wrong team?\n- Anything else that's underspecified enough that engineering would have to guess.\n\nGive your strongest objection(s), each as a specific, concrete gap — not a vague \"consider\" note. Under 350 words."

45	## PO review script
46	
47	1. Confirm Vault Agent Injector annotations/sidecars are present on each consuming Deployment/StatefulSet/Job.
48	2. `kubectl get secret -n loginid-takehome` — confirm none of the six named application secrets appear; confirm the two named TLS-certificate exceptions and the `qa-client-credential` disposition are the only ones present (or absent, per whatever was decided).
49	3. Confirm each Vault role's policy is scoped to exactly its consuming service's own secret path(s) — read the policy directly, not inferred from the manifest alone.
50	4. Confirm Marcus's review of the Vault policies happened and is recorded.
51	4a. **Added per Amber's provisioning pass:** confirm all five workloads have their own named `serviceAccountName` (`api-service`, `api-service-issuer`, `postgres`, `db-migrate`, `idp-connector`) — none running as `default` — and re-run Amber's denial matrix directly (`default` denied all five roles; `idp-connector` denied the `postgres` role; the same SA name in another namespace denied).
52	5. Once deployed: re-review live, per team-lead's own stated plan — confirm the running pods actually receive secret material via Vault Agent (a file mount from the injector sidecar), not a fallback to an old Kubernetes `Secret` left in place by mistake.
53	6. **Added per Tobias's objection, shape confirmed by Amber's pass:** deliberately force an injector failure — remove a role binding, or point a pod's Vault role annotation at a role it isn't bound to — and confirm the pod sits in `Init:CrashLoopBackOff` with a distinguishing log line/event, never a serving pod and never an indefinite silent `Init` hang.
54	7. **Added — closing step, deletion of the six Kubernetes Secrets:** only after this live pass (step 5) has passed and on the PM's explicit word, via the documented runbook. The live check for this step is `kubectl get secrets -n loginid-takehome` showing exactly `postgres-server-tls`, `loginid-takehome-tls`, `qa-client-credential`, and `vault-ca-cert` — nothing else. (Amber's own copy step left the six originals in place deliberately, precisely so this deletion stays a distinct, reviewed, PM-authorized step rather than an automatic side effect of the migration.)

56	## Research team review
57	
58	**Desmond Okafor — claims check:** Verified all six named secrets present with their exact reference locations (grepped both volume-mount and `secretKeyRef` forms, since checking only one under-counts). Count and list confirmed accurate and complete. Found two additional `Secret` references (`postgres-server-tls`, `loginid-takehome-tls`) already named in this doc as platform exceptions, but recommended stating *why* they're excluded more precisely — cert-manager mints/rotates the content itself, no static value for Vault to inject, a mechanistic distinction from the six human-provisioned secrets, not just "standard pattern." Applied.
