1	# LT-49 refinement — S5: observability (logging, metrics, never-log enforcement, retention-sweep alerting)
2	
3	**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`.
4	
5	**Who did the work:** Refined by Naomi Voss (PO).
6	
7	## Why this one, now
8	
9	Per 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.
10	
11	## What this story actually is
12	
13	Not a redesign — `observability.md` already specifies every mechanism this story builds:
14	1. **Logging discipline + lint check** (04): explicit-field `slog` logging, a CI lint rule flagging never-log-list field names/whole-struct log calls.
15	2. **Ingress-level redaction** (04): search-endpoint `name`/`phone` query fragments never reach an ingress access log.
16	3. **Audit-log RBAC** (04): a distinct `Role` for audit-log read access, separate from any Secret-read grant.
17	4. **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).
18	5. **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.
19	
20	This 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).
21	
22	## Acceptance criteria (restated from `backlog.md` S5, split by side)
23	
24	**04 side:**
25	- [ ] 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.
26	- [ ] 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.
27	- [ ] 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.
28	- [ ] `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."
29	- [ ] 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.
30	
31	**03 side:**
32	- [ ] 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).
33	- [ ] 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.
34	
35	**02 side:**
36	- [ ] Marcus (02) confirms in writing that `handoff-04-secrets.md`'s 11-item never-log list is fully covered by a named enforcement site. **Correction (Desmond's claims check):** `observability.md`'s "operationalized" section, as currently written, maps only items 1–9 ("hand-off's nine items map to two enforcement surfaces") — it predates the F50 consistency-pass fix that added items 10 (driver-error `DETAIL` text) and 11 (username) to the hand-off, and was never updated. Marcus's confirmation must therefore supply the missing mapping for items 10–11, not just cross-check an existing mapping that doesn't yet cover them. Flagged to Theo to update `observability.md` itself (source-doc drift, not this refinement's error to carry silently) — see note below.
37	
38	## Source-doc drift found during refinement (Desmond's claims check)
39	
40	Both traced to the same root cause: the F50 consistency-pass fix expanded `handoff-04-secrets.md`'s never-log list from nine items to eleven (items 10–11: driver-error `DETAIL` text, username), and that expansion was never back-propagated into two of 04's own documents:
41	- `observability.md`'s "operationalized" section still says "hand-off's nine items map to two enforcement surfaces" and only enumerates 1–9 — see the 02-side criterion above for the fix this requires.
42	- `04-infra-devops/backlog.md`'s own Story 5 (LT-49) acceptance-criteria text still says "handoff-04-secrets.md's nine items" — stale for the same reason. This refinement doc restates the criterion using the correct, current count (eleven) rather than perpetuating the stale number, but that means this refinement doc's wording will visibly disagree with `backlog.md`'s own text unless Theo corrects nine→eleven there too.
43	
44	Flagged to Theo (04) to fix both source documents directly, since they're his track's files — not something this refinement should silently carry forward or correct in his place.
45	
46	## Priya's seat — retention-alert threshold
47	
48	**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.
49	
50	## Non-goals
51	
52	- No new retention windows or data-class definitions — those are `pii-governance.md`'s numbers, already final per LT-44.
53	- No tracing/OpenTelemetry — explicitly out per `observability.md`'s own "what's deliberately not here."
54	- No general SLO/error-budget policy or alert catalog beyond the one retention-sweep alert rule this story requires.
55	- 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.
56	
57	## PO review script
58	
59	1. 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.
60	2. 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.
61	3. 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.
62	4. 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.
63	5. 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).
64	6. Confirm Marcus's never-log-list completeness confirmation is recorded, and read it against the 11-item list directly rather than trusting a summary.
65	7. 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).
66	8. 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.

With `Forbid`, a skipped run means no new `oldest_surviving_row_age_seconds` line is emitted for that cycle at all — the alert reads the previous run's last value, and whether that's distinguishable from a truly stopped sweep depends on the sink's staleness/retention handling, which nothing in this story or LT-44 currently pins down. Enforcement site: either (a) the same alert rule additionally suppresses/qualifies on LT-44 5a's skip-visibility signal, or (b) a distinct alert exists for \"sweep skipped, still healthy\" vs. \"sweep dead\" — LT-44's own fix (Forbid + skip-visibility metric) must actually feed the one alert it was built to inform, not sit unused."

Not this refinement's error (it correctly uses eleven), but both source docs need Theo's fix.

First, the alert as originally scoped can't distinguish a skipped run (from `Forbid`) from a dead sweep — a skipped run means no new metric line at all for that cycle, so the alert reasons about a stale prior value with no stated staleness handling; LT-44's own skip-visibility fix (5a) needs to actually feed this alert's suppression logic, not sit unused. Second, PO-script step 8 assumed a sweep interval short enough to observe live, but the actual schedule is never stated and is plausibly daily — untestable as originally written. Also flagged that neither side's metrics criterion checked the emitted *value* against ground truth, only that a number reaches the sink. All three fixes applied: the skip-vs-dead suppression requirement added to the 04-side criteria and Priya's question, step 8 rewritten to allow a manual off-schedule trigger, and a new step 4a (seed known-age rows, verify emitted value matches).\n\n**Naomi Voss — ruling:** All fixes from both reviewers applied. This refinement is accepted and ready to hand off, with two flagged items outside this story's own scope: (1) Theo needs to fix the nine→eleven drift in `observability.md` and `backlog.md` directly — not this refinement's job to silently correct another track's source docs; (2) Priya's ruling on the alert-formula question remains genuinely open and must be recorded before this story can be called Done, not before it's handed to engineering to start building the parts that don't depend on her answer (the lint check, ingress redaction, RBAC, and metrics-exposure work can all proceed in parallel).\n\n---\nWork-By: Naomi Voss (PO, refinement + fix incorporation); Desmond Okafor (claims check, source-doc drift finding); Tobias Lindqvist (skip-vs-dead alert objection, PO-script feasibility objection, value-correctness gap)."

Two real findings from the review chain, both fixed in the doc:\n\nDesmond's claims check found source-doc drift: `observability.md`'s \"operationalized\" section and `04-infra-devops/backlog.md`'s own Story 5 text both still say the never-log list has \"nine items\" — stale, predating the F50 fix that brought it to eleven (driver-error DETAIL text, username). Neither this refinement doc's problem to silently patch — flagging for Theo to fix both source docs directly.\n\nTobias's objection found two real gaps I hadn't caught: (1) the alert as scoped can't tell a skipped run (LT-44's `concurrencyPolicy: Forbid` causing the next scheduled run to be skipped, not overlapped) from a genuinely dead sweep — a skipped run means no new metric line at all, so the alert reads a stale prior value with no staleness handling specified; added a criterion requiring LT-44's own skip-visibility fix (5a) to actually feed this alert's suppression logic. (2) PO-script step 8 assumed a sweep interval short enough to observe live in a review session, but nothing states the actual schedule (plausibly daily); rewritten to allow a manual off-schedule trigger as an equivalent proof. Also added a value-correctness check (seed known-age rows, verify the emitted metric matches) that neither side's original criteria covered.\n\nPriya's ruling on the alert-formula question (does skip-visibility alone resolve the skip-vs-dead ambiguity, or does it also need a grace-term) is the one genuinely open question before this can be called Done — everything else (lint check, ingress redaction, RBAC, metrics exposure) can start now in parallel. Ready to hand to Theo/Renata whenever you want it moved.",

1	# LT-46 refinement — Story 2: secret delivery, re-scoped to Vault
2	
3	**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).
4	
5	**Who did the work:** Refined by Naomi Voss (PO); Warren's ruling on the re-scoped criterion.
6	
7	## Why this changed
8	
9	`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.
10	
11	## Re-scoped criterion (replaces the original etcd-encryption line)
12	
13	Application 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.
14	
15	## The six application secrets this criterion covers (enumerated directly from the deployed manifests, not assumed)
16	
17	1. `api-service-jwt-signing-key` — the JWT signing private key, currently mounted only into `api-service-issuer` (LT-32's F13 fix).
18	2. `postgres-superuser` — consumed only by the Postgres `StatefulSet` itself.
19	3. `db-migrator-credential` — the migration-runner credential (DDL rights), consumed by the migration `Job`.
20	4. `db-runtime-credential` — the runtime service credential (DML-only), consumed by `api-service`.
21	5. `issuer-db-migrator-credential` — the issuer's own migration-runner credential (client-store schema).
22	6. `issuer-db-runtime-credential` — the issuer's own runtime credential, consumed by `api-service-issuer`.
23	
24	**Accepted platform exceptions, named explicitly rather than silently grandfathered in as Kubernetes `Secret`s:**
25	- `postgres-server-tls`, `loginid-takehome-tls` — both `cert-manager`-issued TLS certificates (a self-signed `Issuer`/`Certificate` for Postgres; the public Ingress's `letsencrypt-prod`-issued cert). **Excluded on a mechanistic basis, not just convention:** `cert-manager` mints and rotates the certificate content itself — there is no static credential value for Vault to inject, unlike the six secrets above, which are human-provisioned, out-of-band values. This is also the standard TLS-delivery pattern for every other app on this cluster (`decisions/deploy-path.md`). Named explicitly here so a reader isn't left wondering whether these two were simply missed from the count.
26	- **`qa-client-credential` — resolved (Theo + Marcus, jointly):** stays a Kubernetes `Secret`. It's ops/review tooling, never mounted into or consumed by any running pod — a human fetches it via `kubectl` to manually mint a review token — so the Vault Agent Injector pattern doesn't structurally apply to it at all. Confirmed no `ServiceAccount` has any Secrets-API grant (`deploy/rbac.yaml`), so its access boundary remains the existing operator trust boundary (`threat-model.md` Assumption 7), not a new gap this migration needed to close. Recorded in `handoff-04-secrets.md`.
27	
28	## Acceptance criteria for this re-scoped piece
29	
30	- [ ] 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).
31	- [ ] 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.
32	- [ ] 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).
33	- [ ] The migrator/runtime credential separation (criterion 4, unaffected) is preserved under Vault — two distinct Vault paths/roles, not one shared secret with two consumers.
34	- [x] The `qa-client-credential` disposition is decided: stays a Kubernetes `Secret` (see above) — resolved, not ambiguous.
35	- [ ] **Added per Tobias's objection:** a pod whose Vault Agent init-container cannot authenticate or fetch its secret within a bounded timeout fails **visibly** — `CrashLoopBackOff` with a distinguishing log line or event, not an indefinite `Init` hang — matching the fail-loud discipline this project already had to add twice for the same underlying failure shape (`AUTH_JWT_ISSUER`/`AUTH_JWT_AUDIENCE`, then `AUTH_JWKS_URL`: "config the code needs but nothing wired," discovered live both times). This re-scope introduces a new runtime dependency every consuming pod didn't have before (Vault reachable and correctly policy-matched at every startup/restart/rollout, not just at scheduling time, and coupling to a shared-cluster service with its own maintenance windows) — the failure mode for that dependency not being met needs the same explicit treatment, not a silent gap this refinement would otherwise leave for a future live review to rediscover a third time.
36	- [ ] **Added per Amber's provisioning pass:** each of the five workloads (`api-service`, `api-service-issuer`, `postgres`, `db-migrate`, `idp-connector`) runs under its own named ServiceAccount, never `default`. Amber found `postgres` (`StatefulSet`), `db-migrate` (`Job`), and `idp-connector` (`Deployment`) declared no `serviceAccountName` at all and ran as `default` — binding their Vault roles to `default` instead would have let any pod on that SA assume any of the five roles (e.g., `idp-connector`, ruled to get nothing, could have assumed the widest role, `loginid-takehome-postgres`, and read `postgres-superuser`), inverting the least-privilege requirement while appearing to satisfy it. Enforcement site: `deploy/manifests.yaml` declares all five ServiceAccount objects and each workload's `serviceAccountName` explicitly; Amber's own denial matrix (`default` denied all five roles, `idp-connector` denied the `postgres` role, same SA name in a different namespace denied) is the evidence to re-run at review time, not re-derive.
37	- [ ] 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.
38	
39	## Non-goals
40	
41	- 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.
42	- No change to the CI runner's own RBAC (still zero grants on `secrets`, already correct and unaffected by where the secrets themselves live).
43	- No re-litigation of which secrets exist or what they're for — this story is a delivery-mechanism change, not a secrets-inventory redesign.
44	
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.)
55	0. **Added after #56's failed first deploy — read the namespace's resource quota *before* applying, not after:** `kubectl describe resourcequota -n loginid-takehome` (or equivalent), and sum the Vault Agent init/sidecar containers' own default CPU/memory *requests* — not just the application containers' — against headroom under `requests.cpu`/`requests.memory`. #56 failed because five workloads each gaining an injected agent container pushed the namespace over its CPU-request quota, and `postgres-0` (a `StatefulSet`, no rolling-update slack) couldn't schedule at all. This is a pre-deploy check specifically because the failure mode it prevents (a quota rejection) looks identical at a glance to a Vault-auth failure once the pod is already in `Init:CrashLoopBackOff` — cheaper to catch by reading the quota first than to diagnose after the fact.
56	
57	## Research team review
58	
59	**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.
60	
61	**Tobias Lindqvist — objection:** This re-scope introduces a new runtime dependency (Vault reachable and policy-correct at every pod startup/restart/rollout) without stating what happens when that dependency isn't met — the same "config the code needs but nothing wired" failure shape this project has already hit twice (`AUTH_JWT_ISSUER`/`AUTH_JWT_AUDIENCE`, then `AUTH_JWKS_URL`), now with a new entry point (an unreachable or misconfigured Vault) and a new shared-infrastructure coupling (Vault's own maintenance windows now affect this project's pods). 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.
62	
63	**Naomi Voss — ruling:** Both fixes applied. This refinement is accepted and ready to hand off. Tobias's objection is the same recurring pattern this session has now caught four separate times (config/dependency assumed present, never checked against actual failure-mode behavior) — worth treating as a standing lesson for this project's remaining infra stories, not a one-off.

Tobias's objection is the same recurring pattern this session has now caught four separate times (config/dependency assumed present, never checked against actual failure-mode behavior) — worth treating as a standing lesson for this project's remaining infra stories, not a one-off.\n\n## PO acceptance review — live pass against build 5f473e8 (post-#58 hotfix)\n\n**Reviewer:** Naomi Voss (PO), via direct `kubectl` access (context `dev`), 2026-09-13.\n\n**Step 4a — PASS.** `kubectl get pods -n loginid-takehome -o custom-columns=NAME:.metadata.name,SA:.spec.serviceAccountName` confirms all five workloads run under their own named SA (`api-service`, `api-service-issuer`, `postgres`, `db-migrate`, `idp-connector`) — none on `default`. Confirmed each pod's volume list directly: the only `Secret` volumes present anywhere are `vault-ca-cert` (all) and `postgres-server-tls` (postgres only) — no application secret is mounted as a raw Kubernetes `Secret`.\n\n**Pre-deploy quota step (added after #56) — PASS, retroactively.** `kubectl describe resourcequota -n loginid-takehome`: `requests.cpu` 350m/1500m, `requests.memory` 576Mi/2Gi — comfortable headroom under the post-hotfix (pre-populate-only, right-sized agent-container) footprint. This confirms the hotfix actually fixed the quota interaction, not just relocated it.\n\n**Step 6 (forced injector failure) — FAIL, a real gap, not a pass.** I ran this myself: a throwaway pod under the `api-service` ServiceAccount, annotated for Vault injection with `vault.hashicorp.com/role: loginid-takehome-postgres` (a role `api-service` is correctly denied — Vault itself returned `403 service account name not authorized`, confirming the policy boundary holds). But the pod did **not** reach `CrashLoopBackOff`. It sat in `Init:0/1`, `RESTARTS: 0`, for the full ~7 minutes I observed it — the `vault-agent-init` container's own process never exits; it retries authentication forever with a growing internal backoff (26.6s, then 46.55s, presumably continuing to grow), so Kubernetes never sees a container exit to restart. This is precisely the \"indefinite silent `Init` hang\" this criterion was written to rule out, and it's the actual current behavior, not a hypothetical: least-privilege is enforced correctly (the denial itself works), but the failure is invisible by the standard this story itself set — no `CrashLoopBackOff`, no distinguishing terminal state, just a pod that never becomes Ready and never signals why via pod status alone (the reason is in the container's logs, which nothing surfaces to `kubectl get pods`/alerting without someone already knowing to look).\n\n**Disposition:** LT-46 stays In Test. This is not a blocking regression of anything already working (the denial/least-privilege behavior is correct, and the quota/CA-path incident is fully resolved) — it's the one acceptance criterion this refinement itself added that isn't yet met. Needs a fix to the Vault Agent's own retry behavior (e.g., a bounded max-retry count that causes the init container to exit non-zero — Vault Agent supports this via its auto_auth retry configuration, or an equivalent liveness-probe-driven kill on `Init:0/1` pods stuck past a timeout) before this can be called Done. Routing to Theo/Amber.\n\nTest pod cleaned up (`kubectl delete pod lt46-injector-failure-test -n loginid-takehome`) — no lasting change to the cluster."

Two distinct root causes, both fixed in the `#58` hotfix:\n\n1. **Namespace CPU-request quota exceeded.** Each of the five workloads gaining an injected Vault Agent container (sidecar or init) added that container's own default CPU/memory *request* on top of the application container's own — five simultaneous additions pushed the namespace over `requests.cpu` quota. `postgres-0`, a `StatefulSet` with no rolling-update slack, couldn't be (re)scheduled at all as a result. Fixed via explicit `vault.hashicorp.com/agent-limits-cpu`/`-requests-cpu` (and memory) annotations sized down from the injector's defaults, `agent-pre-populate-only: \"true\"` where a sidecar isn't needed after initial render (further shrinking the persistent footprint), and a namespace quota raise. Verified post-fix: `requests.cpu` at 350m/1500m, comfortable headroom (see acceptance review above).\n2. **Wrong CA file path in the issuer's init container.** The `vault.hashicorp.com/agent-extra-secret: vault-ca-cert` annotation mounts the CA secret at `/vault/custom/`, not a subdirectory under it — the issuer's `vault.hashicorp.com/ca-cert` annotation pointed at the wrong path, so Vault Agent's TLS verification against `vault.vault.svc:8200` failed at startup. Fixed by correcting the `ca-cert` annotation to `/vault/custom/ca.crt` (confirmed today at that exact path on every workload's `extra-secrets` volume — see acceptance review above).\n\nAdded to the pre-deploy PO-script step (numbered 0, above): read the namespace quota *before* applying, specifically because a quota rejection and a Vault-auth failure present identically as `Init:CrashLoopBackOff` and are easy to conflate after the fact.\n\n## Research team review"

      was written assuming search takes name/phone as query-string

      body (internal/api/handlers.go's NewSearchHandler). Confirmed the
      real ingress-nginx ConfigMap has no custom log-format override
      (kubectl get configmap -n ingress-nginx ingress-nginx-controller -o
      yaml), so the default access-log format (method+path+protocol only)
      never captures the request body either way. Documented as a live
      tripwire (flag again if a query-string search variant is ever
      added), not a permanently closed question.
    
    Deliberately NOT in this PR: audit-log RBAC and the metrics sink/alert
    rules. Both require live configuration of the cluster's shared
    Elasticsearch/Kibana stack (ns logging) — the actual metrics sink,
    since no Pushgateway exists and standing one up is disproportionate
    scope (established ruling, told to Renata for LT-44/LT-49). That's
    materially more consequential shared-infrastructure surgery than
    anything else built this session (security roles, ingest pipelines,
    alerting rules on a multi-tenant ES cluster with other unrelated
    indices) — checking in with the PM before attempting it live rather
    than assuming the same authorization this track's own Kubernetes-object
    work has had.

 ## The never-log list, operationalized
 
-Hand-off's nine items map to two enforcement surfaces, not nine separate mechanisms:
+**Corrected (LT-49, per Desmond's claims check):** this section previously said "nine items" and enumerated only 1–9 — it predates the cross-track consistency pass (F50) that added items 10 (driver-error `DETAIL` text) and 11 (username) to `handoff-04-secrets.md`'s list, and was never back-propagated. All eleven items map to the same two enforcement surfaces below, not nine:
 
 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.
-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.
+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") was written assuming search takes `name`/`phone` as query-string parameters. **Corrected (LT-49, verified against the real implementation and the real cluster, not assumed):** `internal/app/verifier_router.go` routes search as `POST /profiles/search` with `name`/`phone` in a JSON request body (`internal/api/handlers.go`'s `NewSearchHandler`, `json.NewDecoder(r.Body)`) — there is no query string carrying this data at all. `GET /profiles/{id}` takes an opaque record id as a path segment, not name/phone, so it's not a concern either. Checked the real ingress-nginx ConfigMap directly (`kubectl get configmap -n ingress-nginx ingress-nginx-controller -o yaml`): no custom `log-format-upstream` override exists — the controller uses its default access-log format (`$request` = method, path, protocol only), which never includes the request body regardless. **Net: under the actual implementation and the cluster's current, verified configuration, no query-string PII reaches an ingress access log today** — there is nothing to redact, not because redaction was applied, but because the risk this item names doesn't materialize for this endpoint's actual request shape. This is a live tripwire, not a closed question forever: if a future change ever adds a query-string-based search variant (a GET alternative, a debug endpoint, a redirect that echoes search terms in a URL), the redaction mechanism this item originally called for would then be genuinely needed and does not yet exist — flag that specifically at review time if it comes up, rather than assuming this finding still holds.
 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.
+4. Item 10 (database driver error `DETAIL`/`Key (...)=(...)` text) is the error-path discipline bullet above, applied to 03's own error-translation layer (`error-semantics.md`) specifically: SQLSTATE/result code and constraint name only reach a log call, the sanitization happening before the error is wrapped, not decided case-by-case at the log call itself — application-level, same surface as #1.
+5. Item 11 (username) is the same discipline as item 3: a hash or opaque identifier for correlation, never the raw value, application-level.
 
 ## Audit-log access is a separate grant from Secret access

 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.
 
-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.
+Mechanism: the sweep job (a `CronJob`, `deploy/manifests.yaml`, schedule `17 3 * * *` — I = 24h = `sweep_interval_seconds` = 86400) 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.)
+
+**Alert rule, per Priya Nandakumar's (05) LT-49 ruling — three rules, none suppressing another** (superseding this section's earlier single-formula design, `refinement/LT-49.md`): a single "age exceeds window + interval" formula can't tell a `concurrencyPolicy: Forbid`-skipped run from a dead sweep, and suppressing on the skip signal is actively dangerous — a chronically-overrunning sweep would emit a skip signal every interval and permanently silence the one alert meant to catch it. Let **W** = the class's retention window, **I** = `sweep_interval_seconds` (86400):
+
+1. **`RetentionSweepNotReporting`** (per class): fires when no fresh `oldest_surviving_row_age_seconds` sample for that class in more than **2I**. A single skip produces a gap of exactly 2I and does not fire (the grace for a skip); two consecutive skips (3I) does fire, as does a genuinely dead sweep. Counts missed samples rather than trusting an explanation — does not consume the skip-visibility signal at all.
+2. **`RetentionWindowExceeded`** (per class): fires when `oldest_surviving_row_age_seconds{class} > W + 2I`. The first `I` is legitimate lag (a row becomes eligible just after one sweep and waits a full interval for the next); the second absorbs one skipped run. Assumes sweep duration `D < I` — if `D` approaches `I`, rule 3 is the real signal.
+3. **`RetentionSweepSkipRate`** (low severity, early warning): fires when skipped runs exceed ~25% over a rolling day. This is where LT-44's `concurrencyPolicy: Forbid` skip-visibility signal (the `JobAlreadyActive` event) is actually consumed — as evidence in its own right, never as a suppression term on rules 1 or 2.
+
+A sweep that runs but never drains (hitting `maxRows` every batch) emits no valid sample and correctly trips rule 1 — that is the intended behavior, not a false positive to "fix" by publishing non-drained values (see the batching note below).
 
 **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.

55	- No general SLO/error-budget policy or alert catalog beyond the one retention-sweep alert rule this story requires.
56	- 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.
57	
58	## PO review script
59	
60	1. 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.
61	2. 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.
62	3. 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.
63	4. 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.
64	4a. **Added per Tobias's objection — value correctness, not just presence:** seed one row of known age in each retention class, run the sweep once, query the sink for that class's `oldest_surviving_row_age_seconds`, and confirm the value is within a few seconds of the known seeded age — not merely that a number arrived. Neither side's criterion above checks the emitted value against ground truth on its own; this step closes that gap without duplicating either team's enforcement site.
65	5. 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).
66	6. Confirm Marcus's never-log-list completeness confirmation is recorded, and read it against the 11-item list directly rather than trusting a summary — including items 10–11, per the source-doc-drift note above.
67	7. 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) and that the skip-vs-dead suppression logic is actually wired in, not just designed.
68	8. **Rewritten per Tobias's objection — the original "suspend and wait one sweep interval" step assumed a short enough interval to observe live within a review session, but nothing in this story or LT-44 states the CronJob's actual schedule (plausibly daily, given the 24-month/30-day/7-day retention regime).** Cite the real schedule value here once Theo's manifest sets it; if it's longer than a review session can wait out, substitute a manually-triggered, off-schedule one-off `Job` run (bypassing the CronJob's own cadence) as the equivalent live proof that a dead/stopped sweep produces no other symptom and the alert correctly fires once its condition is met.
69	
70	## Research team review
71	
72	**Desmond Okafor — claims check:** Verified the `observability.md`/`handoff-04-secrets.md`/`LT-44.md`/`backlog.md` claims directly. One real finding: `observability.md`'s "operationalized" section and `backlog.md`'s own Story 5 text both still say "nine items," predating the F50 consistency-pass fix that brought the never-log list to eleven — neither was back-propagated. Not this refinement's error (it correctly uses eleven), but both source docs need Theo's fix. Everything else — the alert formula, `Drained`-only gating, the 11-item count and items 10/11's content, LT-44's metric names/class labels/`Forbid` — verified accurate.
73	
74	**Tobias Lindqvist — objection:** Two real gaps. First, the alert as originally scoped can't distinguish a skipped run (from `Forbid`) from a dead sweep — a skipped run means no new metric line at all for that cycle, so the alert reasons about a stale prior value with no stated staleness handling; LT-44's own skip-visibility fix (5a) needs to actually feed this alert's suppression logic, not sit unused. Second, PO-script step 8 assumed a sweep interval short enough to observe live, but the actual schedule is never stated and is plausibly daily — untestable as originally written. Also flagged that neither side's metrics criterion checked the emitted *value* against ground truth, only that a number reaches the sink. All three fixes applied: the skip-vs-dead suppression requirement added to the 04-side criteria and Priya's question, step 8 rewritten to allow a manual off-schedule trigger, and a new step 4a (seed known-age rows, verify emitted value matches).
75	
76	**Naomi Voss — ruling:** All fixes from both reviewers applied. This refinement is accepted and ready to hand off, with two flagged items outside this story's own scope: (1) Theo needs to fix the nine→eleven drift in `observability.md` and `backlog.md` directly — not this refinement's job to silently correct another track's source docs; (2) Priya's ruling on the alert-formula question remains genuinely open and must be recorded before this story can be called Done, not before it's handed to engineering to start building the parts that don't depend on her answer (the lint check, ingress redaction, RBAC, and metrics-exposure work can all proceed in parallel).
77	
78	## Priya Nandakumar's ruling — the alert formula (05)
79	
80	**Answer: skip-visibility alone is not sufficient, a grace term is needed, and — most importantly — skip-visibility must NOT be used as a suppression term.** Three alerts on three properties, none suppressing another.
81	
82	### Why suppression-on-skip is the dangerous option
83	
84	If the alert is silenced whenever a skip signal was emitted, then a sweep that *chronically* overruns — every scheduled run skipped because the previous never finished — emits a skip signal every interval and **suppresses the alert permanently.** The suppression mechanism becomes the failure mode, and it does so precisely when the sweep is failing hardest. A single skip and an endless run are indistinguishable by the presence of a skip signal; they differ only in how many consecutive intervals produce no fresh sample.

78	## Priya Nandakumar's ruling — the alert formula (05)
79	
80	**Answer: skip-visibility alone is not sufficient, a grace term is needed, and — most importantly — skip-visibility must NOT be used as a suppression term.** Three alerts on three properties, none suppressing another.
81	
82	### Why suppression-on-skip is the dangerous option
83	
84	If the alert is silenced whenever a skip signal was emitted, then a sweep that *chronically* overruns — every scheduled run skipped because the previous never finished — emits a skip signal every interval and **suppresses the alert permanently.** The suppression mechanism becomes the failure mode, and it does so precisely when the sweep is failing hardest. A single skip and an endless run are indistinguishable by the presence of a skip signal; they differ only in how many consecutive intervals produce no fresh sample.
85	
86	This is the same error as alerting on the mechanism rather than the property. The property is *"is data surviving past its retention window, and is the sweep still reporting?"* — neither of which is answered by "was a run skipped."
87	
88	### The three rules
89	
90	Let **W** = the class's retention window, **I** = the CronJob interval, **D** = a sweep run's duration.
91	
92	**1. `RetentionSweepNotReporting` — per class.** Fires when no fresh `oldest_surviving_row_age_seconds` sample for that class in **more than 2I**.
93	
94	A single skip produces a gap of exactly 2I (sample at *t*, next at *t*+2I), so it does not fire — that is the grace for the case this question is about. Two consecutive skips produce 3I and it fires. A dead sweep fires. **This is the alert that distinguishes skipped from dead, and it does so without consuming the skip signal at all** — by counting missed samples rather than by trusting an explanation.
95	
96	**Per class, not global**, because the sweep is per class by contract (`multi-db-strategy.md` §3c — `DeleteExpired(ctx, class, olderThan, maxRows)`, one class per call). A class whose step errors while the others succeed would keep the global series fresh and go silent unnoticed.
97	
98	**2. `RetentionWindowExceeded` — per class.** Fires when `oldest_surviving_row_age_seconds{class} > W + 2I`.
99	
100	**The third term is `2I`, not `I`.** One I is the legitimate lag — a row becomes eligible just after a sweep completes and waits a full interval for the next one, so a healthy system reaches W + I routinely and an alert at W + I fires on every normal cycle. The second I absorbs one skipped run. This assumes **D < I**; if D approaches I the sweep is not keeping up and rule 3 is the real signal.
101	
102	**3. `RetentionSweepSkipRate` — low severity, the early warning.** Fires when skipped runs exceed ~25% over a rolling day. **This is where LT-44 5a's skip-visibility signal is consumed** — as evidence in its own right, not as a suppression term on rules 1 or 2. It catches "the sweep is completing but only just" before either of the others trips.
103	
104	### Numbers, at I = 24h
105	
106	Theo substitutes the real interval; these are the values if the CronJob is daily.
107	
108	| Class | W | Rule 2 threshold (W + 2I) | Seconds |
109	|---|---|---|---|
110	| `idp_cache_orphan` | 7 days | 9 days | 777600 |
111	| `idp_cache` | 30 days | 32 days | 2764800 |
112	| `direct` | 24 months (730d) | 732 days | 63244800 |
113	
114	Rule 1 threshold is **2I = 172800 s** for every class.
115	
116	**If I changes, rules 1 and 2 both change.** They are expressed in terms of I deliberately: a hardcoded 9 days silently becomes wrong the moment the schedule moves to twice daily or weekly. Prefer deriving them from one `sweep_interval_seconds` constant in the rule config over writing the arithmetic out.

Pulled `f6f05ac` into `/tmp/lt34review` and verified directly rather than trusting the PR description.\n\n**Lint check — PASS, verified the right way.** My first attempt to verify it (passing a scratch directory as a CLI argument) silently no-opped: `scripts/check-never-log.py`'s `main()` hardcodes `root = Path(__file__).resolve().parent.parent` and never reads `sys.argv` — any path argument is ignored, and it always scans the real repo's `internal`/`cmd`. Not a functional bug (CI's own invocation, `python3 scripts/check-never-log.py`, takes no argument and doesn't need one), but worth noting since it means a reviewer can't sanity-check it against a disposable scratch tree the way I first tried. Verified it for real by temporarily appending a violation (a `password` argument to `log.Printf`) directly into `internal/config/config.go`, confirming `exit=1` with the correct file:line, then reverting the file and confirming `git status` clean. Confirmed wired into `pr-check.yml`'s `never-log-lint` job with no path argument.\n\n**Nine→eleven drift fix — PASS.** Read both corrected files directly: `observability.md`'s \"operationalized\" section now states \"all eleven items\" and adds items 10/11 to the same two-enforcement-surface mapping; `backlog.md`'s Story 5 text corrected alongside it.\n\n**Ingress-redaction finding — PASS, and it's a good catch.** Theo's finding that item 9 was written assuming query-string search params, when the real handler (`internal/api/handlers.go`'s `NewSearchHandler`) takes `name`/`phone` in a JSON body, is exactly the kind of live-verified correction this project's review chain has rewarded elsewhere (e.g. LT-49's own metric-class-name fix, LT-41's outage findings) — checked against the real ingress-nginx `ConfigMap` too, not just the handler code. Documented correctly as a live tripwire (re-check if a query-string search variant is ever added), not a permanently closed question — the right level of confidence for something checked mechanistically but not enforced structurally.\n\n**Priya's three-rule alert design — PASS, matches `observability.md` exactly.** Cross-read the ruling above against `observability.md`'s own alert-rule section: `RetentionSweepNotReporting` (2I gap threshold), `RetentionWindowExceeded` (W + 2I), `RetentionSweepSkipRate` (~25%/day, the only rule consuming LT-44 5a's skip-visibility signal, as evidence not suppression) — identical in both places, and the reasoning for rejecting suppression-on-skip (a chronically-overrunning sweep would permanently silence its own alert) directly answers the question I routed to her. This closes the open item from my own ruling above.\n\n**Deliberately deferred, not a gap:** audit-log RBAC and the metrics sink/alert-rule wiring are explicitly out of this PR — both require live configuration of the cluster's shared, multi-tenant Elasticsearch/Kibana stack, which Theo is right to check in with the PM about before touching rather than assuming the same authorization his Kubernetes-object work has had. Noted, not blocking this partial review; LT-49 remains open pending that second PR.\n\n---\nWork-By: Naomi Voss (PO, refinement + acceptance review of part 1); Desmond Okafor (claims check, drift finding); Tobias Lindqvist (alert skip-vs-dead objection, PO-script objection); Priya Nandakumar (05, alert-formula ruling); Theo Bergman (04, lint check + doc fixes + ingress finding + alert-rule rewrite)."

55	5a. **Added per Tobias's objection:** read the `CronJob` manifest directly and confirm `concurrencyPolicy: Forbid` is set, not the Kubernetes default `Allow`; confirm a skipped-due-to-overlap run is itself visible in observability (a metric or log line), not silently invisible.
56	6. Once deployed: confirm the `CronJob` actually runs on schedule (check its last-run status via `kubectl get cronjob`/`kubectl get jobs`) and that at least one run reports real `rows_examined`/`rows_deleted` numbers, not zero-across-the-board from day one (which would be consistent with either a genuinely empty table or a broken sweep — the seeded demo profiles, if old enough, are one way to get a non-trivial signal; otherwise this criterion is "ran without erroring," not "deleted something").

58	## Research team review
59	
60	**Desmond Okafor — claims check:** Verified the full retention-class/window/clock table and every metrics/label requirement word-for-word against `pii-governance.md` and `observability.md` directly — all accurate. Independently re-checked the DAO-level test claims (rather than trusting his own earlier LT-42 sweep, which hadn't actually named this specific package) — found every cited test present in `internal/dao/conformance/conformance_test.go`, plus the `Drained`/`OldestSurvivingAt` doc comment in `retention.go`. No corrections needed.
61	
62	**Tobias Lindqvist — objection:** The `CronJob` had no stated `concurrencyPolicy`, leaving Kubernetes' default `Allow` in place — a slow first-ever sweep run (plausible, given no prior sweep history and a possible real backlog) could overlap with its own next scheduled invocation, recreating the exact "two schedulers hit the same tables concurrently" risk this project already solved once for the migration `Job` in LT-45, never carried forward here. Beyond wasted load, overlapping sweeps could each independently emit `oldest_surviving_row_age_seconds` for the same class, undermining the one metric the alert rule depends on being trustworthy. Counter-proposal accepted: `concurrencyPolicy: Forbid`, plus a requirement that a skipped-due-to-overlap run be itself visible in observability, not silently invisible.
63	
64	**Naomi Voss — ruling:** Fix applied. This refinement is accepted and ready to hand off. This is the fourth story in this chain where a pattern already established elsewhere in the project (single-in-flight discipline on the migration `Job`) wasn't carried forward to a structurally identical new component — worth naming as its own recurring category, alongside the NetworkPolicy-scoping pattern Tobias already flagged on LT-52.

66	## Update — implementation (Renata Cole, 03), entrypoint/args agreed with Theo (04) first
67	
68	**Entrypoint, agreed with Theo before opening the PR:** `APP_MODE=sweep`, a third value alongside `verifier`/`issuer` on the SAME `api-service` binary/image — not a `--sweep` CLI flag, and not a distinct `cmd/sweep-worker` binary. Theo's own reasoning, adopted: `config.Load`/`cmd/api-service/main.go` already dispatch on `APP_MODE`, so a third value keeps one mode-selection mechanism instead of introducing a second (env var + CLI flag) in the same binary. The `CronJob`'s container just sets `APP_MODE: sweep` plus `DB_DRIVER`/`DB_DSN_FILE` (same as every other Deployment) — no `command`/`args` override needed. `internal/app.ModeSweep` is the new typed constant; `config.Load` accepts it; `config.RequiredAuthEnvVars("api-service", "sweep")` returns `(nil, true)` — recognized, requiring nothing, since sweep mode never verifies or issues a JWT.

Ran the review script's off-schedule trigger (`kubectl -n loginid-takehome create job --from=cronjob/retention-sweep lt44-review-1`) exactly as written.\n\n**Real finding: the retention-sweep Job cannot reach Postgres at all — silently, indefinitely, and undetected by any mechanism this story or LT-49 has built so far.** The triggered Job's pod sat `1/1 Running` for over two minutes with **zero log output** (not even a startup line) and **~1m CPU** (essentially idle, not busy). `pg_stat_activity` on `postgres-0` showed no incoming connection from the sweep pod at all. A `kubectl debug` ephemeral container attached to the pod's network namespace showed exactly one TCP socket, in **`SYN_SENT`** state, addressed to `postgres-0`'s real IP on port 5432, with a nonzero retransmit count — packets going out, nothing coming back. Not a connection refusal (which would show a completed handshake followed by a reset, and would appear in Postgres's own connection log) — a **silent drop**, which pointed straight at `NetworkPolicy`.\n\n**Root cause, confirmed by reading the manifest directly:** `postgres-default-deny`'s ingress allow-list is `podSelector.matchLabels` for `app=api-service`, `app=api-service-issuer`, `app=db-migrate` only. The retention-sweep `CronJob`'s pod template labels itself `app: retention-sweep` (confirmed in the CronJob spec) — a fourth, structurally identical consumer of Postgres that was never added to the policy's allow-list. Exactly the same category of gap Tobias already flagged on LT-52 (NetworkPolicy scoping not carried forward to a new, structurally identical component) and the fourth-in-a-row instance of \"a pattern already established elsewhere in the project wasn't carried forward to a new component,\" per my own ruling above on the `concurrencyPolicy: Forbid` finding — this is a fifth.\n\n**Why this is worse than a normal failed sweep, not just another instance of the same bug:** the Job has no `activeDeadlineSeconds` set, so it would run forever, never completing and never failing — meaning under `concurrencyPolicy: Forbid`, every subsequent scheduled run would be silently skipped forever, since the hung Job never releases the \"active\" slot. `RetentionSweepNotReporting` (LT-49, Priya's rule 1) would eventually catch this (no fresh sample for 2I — up to 48 hours at a daily schedule), but that's a two-day-late detection of a bug that's actually immediate and permanent, not a legitimately slow sweep.\n\n**Disposition: LT-44 stays In Test, this is a FAIL, not a partial pass.** Fix needed: add `podSelector: matchLabels: app: retention-sweep` to `postgres-default-deny`'s ingress `from` list. Test job (`lt44-review-1`) deleted; no lasting change to the cluster. The concurrent-trigger check (confirm `JobAlreadyActive`) is deferred until after this fix, since testing concurrency against a Job that can never complete would prove nothing.\n\nRouting to Theo (04, owns the NetworkPolicy manifest) and Renata (03, so she's aware the sweep code itself was never actually exercised against a live database by this review)."

The Job's pod sat 1/1 Running for 2+ minutes with zero log output and ~1m CPU — essentially idle, not busy. pg_stat_activity on postgres-0 showed no incoming connection attempt at all. Attached a kubectl debug ephemeral container to the pod's netns: exactly one TCP socket, SYN_SENT, addressed to postgres-0's real IP:5432, retransmitting — packets going out, nothing coming back. Not a refusal (would show a completed handshake + reset, and would show up in Postgres's own log) — a silent drop.\n\nRoot cause, confirmed by reading the manifest directly: postgres-default-deny's NetworkPolicy ingress allow-list is app=api-service/api-service-issuer/db-migrate only. The retention-sweep CronJob's pods label themselves app=retention-sweep — a fourth, structurally identical Postgres consumer that was never added to the policy. Same category as Tobias's LT-52 NetworkPolicy-scoping catch and my own Forbid-carryforward finding on this same story — this is the fifth instance of \"a pattern established elsewhere wasn't carried to a new, identical component.\"\n\nWorse than an ordinary broken sweep: the Job has no activeDeadlineSeconds, so it runs forever, never completing — meaning under Forbid, every future scheduled run gets silently skipped forever too, since the hung Job never frees the active slot. LT-49's RetentionSweepNotReporting alert would eventually catch this (up to 48h at a daily schedule) but that's a slow detection of what's actually an immediate, permanent failure.\n\nFix: add `app: retention-sweep` to postgres-default-deny's ingress allow-list. Test job cleaned up, no lasting cluster change. Deferring the concurrent-trigger (JobAlreadyActive) check until after this fix — testing concurrency against a Job that can never complete proves nothing. Recorded in full in refinement/LT-44.md.

Caught and corrected this as a test-construction error before drawing any conclusion from it, not a product finding — rebuilt the test pod with `restartPolicy: Always`, matching the real Deployments this annotation actually protects.\n\n**Result: PASS.** With the corrected test: `Init:Error` at 3s → `Init:CrashLoopBackOff` at 36s, restart count climbing (2, then 3) as expected — visible directly via `kubectl get pods`, no log read required to see the failure state. Confirmed the underlying cause is unchanged and correct via the init container's own final log line: `Code: 403. Errors: * service account name not authorized`, `exitCode=1` — the same least-privilege denial as before, now actually terminating instead of retrying forever. Test pod deleted, no lasting cluster change.\n\n**Verdict: LT-46 PASSES.** All criteria met: 4a (SA-per-workload), the pre-deploy quota check, step 5 (live Vault-delivered secrets, no fallback), step 6 (fail-loud, now genuinely CrashLoopBackOff within ~36s, well under the \"about a minute\" expectation), Marcus's policy review recorded.

66	## Update — implementation (Renata Cole, 03), entrypoint/args agreed with Theo (04) first
67	
68	**Entrypoint, agreed with Theo before opening the PR:** `APP_MODE=sweep`, a third value alongside `verifier`/`issuer` on the SAME `api-service` binary/image — not a `--sweep` CLI flag, and not a distinct `cmd/sweep-worker` binary. Theo's own reasoning, adopted: `config.Load`/`cmd/api-service/main.go` already dispatch on `APP_MODE`, so a third value keeps one mode-selection mechanism instead of introducing a second (env var + CLI flag) in the same binary. The `CronJob`'s container just sets `APP_MODE: sweep` plus `DB_DRIVER`/`DB_DSN_FILE` (same as every other Deployment) — no `command`/`args` override needed. `internal/app.ModeSweep` is the new typed constant; `config.Load` accepts it; `config.RequiredAuthEnvVars("api-service", "sweep")` returns `(nil, true)` — recognized, requiring nothing, since sweep mode never verifies or issues a JWT.
69	
70	## PO acceptance review — live pass against build f6f05ac (real bug found, FAIL)
71	
72	**Reviewer:** Naomi Voss (PO), via direct `kubectl` access, 2026-09-13. Ran the review script's off-schedule trigger (`kubectl -n loginid-takehome create job --from=cronjob/retention-sweep lt44-review-1`) exactly as written.
73	
74	**Real finding: the retention-sweep Job cannot reach Postgres at all — silently, indefinitely, and undetected by any mechanism this story or LT-49 has built so far.** The triggered Job's pod sat `1/1 Running` for over two minutes with **zero log output** (not even a startup line) and **~1m CPU** (essentially idle, not busy). `pg_stat_activity` on `postgres-0` showed no incoming connection from the sweep pod at all. A `kubectl debug` ephemeral container attached to the pod's network namespace showed exactly one TCP socket, in **`SYN_SENT`** state, addressed to `postgres-0`'s real IP on port 5432, with a nonzero retransmit count — packets going out, nothing coming back. Not a connection refusal (which would show a completed handshake followed by a reset, and would appear in Postgres's own connection log) — a **silent drop**, which pointed straight at `NetworkPolicy`.
75	
76	**Root cause, confirmed by reading the manifest directly:** `postgres-default-deny`'s ingress allow-list is `podSelector.matchLabels` for `app=api-service`, `app=api-service-issuer`, `app=db-migrate` only. The retention-sweep `CronJob`'s pod template labels itself `app: retention-sweep` (confirmed in the CronJob spec) — a fourth, structurally identical consumer of Postgres that was never added to the policy's allow-list. Exactly the same category of gap Tobias already flagged on LT-52 (NetworkPolicy scoping not carried forward to a new, structurally identical component) and the fourth-in-a-row instance of "a pattern already established elsewhere in the project wasn't carried forward to a new component," per my own ruling above on the `concurrencyPolicy: Forbid` finding — this is a fifth.
77	
78	**Why this is worse than a normal failed sweep, not just another instance of the same bug:** the Job has no `activeDeadlineSeconds` set, so it would run forever, never completing and never failing — meaning under `concurrencyPolicy: Forbid`, every subsequent scheduled run would be silently skipped forever, since the hung Job never releases the "active" slot. `RetentionSweepNotReporting` (LT-49, Priya's rule 1) would eventually catch this (no fresh sample for 2I — up to 48 hours at a daily schedule), but that's a two-day-late detection of a bug that's actually immediate and permanent, not a legitimately slow sweep.
79	
80	**Disposition: LT-44 stays In Test, this is a FAIL, not a partial pass.** Fix needed: add `podSelector: matchLabels: app: retention-sweep` to `postgres-default-deny`'s ingress `from` list. Test job (`lt44-review-1`) deleted; no lasting change to the cluster. The concurrent-trigger check (confirm `JobAlreadyActive`) is deferred until after this fix, since testing concurrency against a Job that can never complete would prove nothing.
81	
82	Routing to Theo (04, owns the NetworkPolicy manifest) and Renata (03, so she's aware the sweep code itself was never actually exercised against a live database by this review).
83	
84	**Config:** reuses `DB_DRIVER`/`DB_DSN` as-is, no new DB env vars. Retention windows (24 months/30 days/7 days) and `maxRowsPerBatch` (1000, inside the DAO's own validated 1..10,000 range) are hardcoded constants in `internal/sweep`, not new env vars — per this story's own "not this story's job to decide the numbers" framing, confirmed with Theo.
85	
86	**Metrics, agreed with Theo:** stdout lines in a `metric_name{label="value"} value` shape (`internal/sweep.StdoutMetricEmitter`) are the complete, final answer for this project's scope — not a placeholder. Checked against the real cluster: `kube-prometheus-stack` is deployed but there's no Pushgateway, which is the actually-correct tool for a short-lived batch job's metrics (a CronJob pod is typically gone before Prometheus's own scrape interval could catch it), and standing one up is new infrastructure disproportionate to this story's "half-day" framing. Theo is documenting Pushgateway as the named production next step in a decisions doc, so this is a stated scope limit, not a silent gap. `oldest_surviving_row_age_seconds` is emitted only from a `Drained == true` batch, per `internal/sweep.runClass`'s own gating — verified by a dedicated test (`TestRun_MetricsOnlyEmittedOnDrained`) asserting a non-drained intermediate batch never triggers a metrics call.
87	
88	**`internal/sweep.Run`** loops `DeleteExpired` per `RetentionClass` until `Drained`, one class at a time (never a mixed predicate, verified by `TestRun_EveryClassCalledOnceEachWithItsOwnPredicate`), summing `RowsExamined`/`RowsDeleted` across every batch a class takes to drain. A cancelled context stops before any class calls `DeleteExpired` at all (`TestRun_AlreadyCancelledContextDeletesNothing`) — `cmd/api-service`'s own `runSweepMode` derives its context from `signal.NotifyContext` (SIGTERM/SIGINT), never a request-scoped one, since there is no HTTP request anywhere in this invocation. One class's error doesn't block the other two (`TestRun_OneClassErrorDoesNotBlockTheOthers`) — a database hiccup on one class shouldn't waste a full sweep of the other two, and a failed class's metrics are never emitted (would be misleadingly partial).
89	
90	**Live-verified, not just unit-tested:** ran the actual `api-service` binary with `APP_MODE=sweep` against a real throwaway Postgres container, seeded with rows spanning all three classes (some stale, some fresh). Confirmed: only the stale rows were deleted, the fresh rows survived, `deletion_log` recorded exactly 3 rows with `reason=retention_sweep`, and the emitted metric lines matched the actual examined/deleted counts.

92	`DeleteProfile` (subject-deletion path) is untouched by this story, per its own non-goal — no subject-deletion-request endpoint exists to wire it to.

67:## Story 4 — Local dev-loop: compose profiles for SQLite and Postgres (LT-48)
68-
69-**Description:** Build the `docker-compose.yml` in `./local-dev-loop.md`: `sqlite` and `postgres` profiles matching 03's `DB_DRIVER` env var, a mock/local `idp-connector` target, hot-reload (`air`) for `api-service` in dev profiles only, and local-only dev credentials clearly distinguished from the real secrets mechanism (Story 2).
70-
71-**Acceptance criteria:**
72-- [ ] A new developer can run either profile from this file alone, without asking what `DB_DRIVER` values are valid.
73-- [ ] The `postgres` profile exercises the shared `postgres`-package code path (Postgres + CockroachDB) — enforcement site: compose service definition wiring `DB_DRIVER=postgres`.
74-- [ ] Dev credentials never appear in `./secrets-delivery.md`'s mechanism or in any real manifest — enforcement site: explicit statement in the file plus separate variable naming (`dev`/`dev`, hardcoded client id/secret).
75-- [ ] Hot-reload has zero effect on the production image build — enforcement site: `air` target scoped to compose dev profiles only, never `./containerization-design.md`'s Dockerfile.
76-
77-**Depends on:** 03 — `DB_DRIVER`/config-surface env vars (already stable, per `PLANNING.md`).
78-
79-**Model/effort:** Sonnet, low.
80-
81-**Type:** Story.
82-
83-**Labels:** `track-04`, `no-code-yet`.
84-
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 eleven items, per the F50 consistency-pass additions of items 10-11) 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.

# Local Dev-Loop

Design-only — a docker-compose sketch, not a committed `docker-compose.yml`. Local counterpart to the cluster target in `./containerization-design.md`, not a replacement for it: this is what a developer runs on a laptop; the cluster design is what the submission targets as the real deployment shape.

## Two compose profiles, matching 03's `DB_DRIVER` env var

```yaml
# docker-compose.yml (sketch)
services:
  api-service:
    build: {context: ., dockerfile: cmd/api-service/Dockerfile}
    environment:
      DB_DRIVER: ${DB_DRIVER:-sqlite}
      DB_DSN_FILE: /run/secrets/db_dsn
      HTTP_ADDR: ":8080"
    ports: ["8080:8080"]
    volumes: ["sqlite-data:/data"]
    secrets: [db_dsn]
    profiles: ["sqlite"]

  api-service-pg:
    extends: {service: api-service}
    environment:
      DB_DRIVER: postgres
    depends_on: [postgres]
    profiles: ["postgres"]

  postgres:
    image: postgres:16-alpine
    environment:
      POSTGRES_USER: dev
      POSTGRES_PASSWORD_FILE: /run/secrets/postgres_password
    ports: ["5432:5432"]
    secrets: [postgres_password]
    profiles: ["postgres"]

  idp-connector:
    build: {context: ., dockerfile: cmd/idp-connector/Dockerfile}
    environment:
      IDP_ABC_BASE_URL: ${IDP_ABC_BASE_URL:-http://mock-idp:9090}
    secrets: [idp_abc_client_id, idp_abc_client_secret]
    profiles: ["sqlite", "postgres"]

secrets:
  db_dsn: {file: ./.dev-secrets/db_dsn}                       # untracked; developer creates once, e.g. "file:/data/dev.db" or a postgres:// DSN
  postgres_password: {file: ./.dev-secrets/postgres_password}
  idp_abc_client_id: {file: ./.dev-secrets/idp_abc_client_id}
  idp_abc_client_secret: {file: ./.dev-secrets/idp_abc_client_secret}

volumes:
  sqlite-data:
```

`.dev-secrets/` is `.gitignore`d; a `.dev-secrets/README` (or a `make dev-secrets-init` target) writes the four files with placeholder dev values on first run. This isn't cosmetic — the inventory's rules apply to every environment, including dev: row 5 says vendor client credentials are "never in source or committed config", and row 1's `DB_DSN_FILE` is "Required, not preferred," with no development exemption written anywhere. Compose's file-based `secrets:` mechanism is the local equivalent of the `Secret` volume mounts in `./secrets-delivery.md` — same shape (a file path the process reads), just backed by a bind-mounted file instead of a Kubernetes object.

`docker compose --profile sqlite up` for the zero-dependency path (no Postgres container, fastest inner loop); `docker compose --profile postgres up` when a developer needs to exercise the Postgres-specific code path (the `pg_trgm` index, per `../05-data-ops/multi-db-strategy.md`). CockroachDB is omitted here for loop speed, not because it's redundant — the CockroachDB code path (`withRetry`'s engine-aware retry, `multi-db-strategy.md`) is genuinely different code from the Postgres path, which is exactly why `./ci-pipeline.md` runs a dedicated CockroachDB job; the local loop just doesn't need every backend on every save.

## Dev credentials are dev credentials

The values developers put in `.dev-secrets/*` are local-only, never used outside a developer's own machine, and never the pattern used in `./containerization-design.md` or `./secrets-delivery.md` — those go through the mechanisms 02 specifies. Worth stating explicitly so nobody reads this file as the security design.

## Migrations locally

`goose up` (or whatever 05 finalizes) run by hand or via a `make migrate` target against whichever profile is active — no orchestration-layer exclusivity needed locally since there's exactly one developer and one instance. The R2 requirement (`../05-data-ops/migration-approach.md`) is a production/CI concern; the local loop doesn't need to simulate it.

## Hot-reload for `api-service`, dev-profile only

Considered cutting `air` as unneeded polish, reconsidered: `docker compose build && up` on every change is a slow inner loop for a project a developer iterates on repeatedly, and the cost of adding it is close to zero — one `air`-based dev target in the compose file, no production image impact since it only applies to the `sqlite`/`postgres` dev profiles, never `./containerization-design.md`'s images. Worth doing, not worth debating further.

## What's deliberately not here

No local Kubernetes (`kind`/`minikube`) mirroring the lab cluster — compose is the right altitude for a two-service Go project's local loop; a local k8s cluster would be solving a problem this project doesn't have.

Not a redesign — the design doc is explicit that this is a sketch to commit, not a proposal to re-litigate.\n\n## Acceptance criteria (restated from `backlog.md` S4)\n\n- [ ] A new developer can run either profile (`docker compose --profile sqlite up` / `--profile postgres up`) from this file alone, without asking what `DB_DRIVER` values are valid — enforcement site: the compose file itself states valid values, no external doc required to start.\n- [ ] The `postgres` profile exercises the shared `postgres`-package code path (Postgres, and by extension CockroachDB's shared code) — enforcement site: `api-service-pg`'s `DB_DRIVER: postgres` wiring.\n- [ ] Dev credentials never appear in `secrets-delivery.md`'s mechanism or in any real manifest — enforcement site: `.dev-secrets/` is `.gitignore`d, values are placeholder/dev-only, and the file states explicitly (as `local-dev-loop.md` already does) that this isn't the security design.\n- [ ] Hot-reload (`air`) has zero effect on the production image build — enforcement site: the `air` target/service is scoped to compose dev profiles only; `cmd/api-service/Dockerfile` (the actual production build, `containerization-design.md`) is untouched by this story.\n- [ ] **Added — `.gitignore` actually covers `.dev-secrets/`,** checked directly rather than assumed: a placeholder-credential file that *should* be untracked but isn't would be a real, if low-severity, instance of the same \"committed secret-shaped value\" concern this project polices everywhere else (`gitleaks` in CI, the never-log list). Enforcement site: `.gitignore` entry, confirmed present, plus a `git status` check post-`make dev-secrets-init` showing the four files as untracked.\n- [ ] **Added — the `postgres` profile's `postgres` service doesn't collide with the real cluster's own Postgres on a developer's machine** (both default to port 5432) — not a security concern, a \"second thing entirely eats a dev's afternoon\" concern (this project has already lost time to unrelated-looking failures that were actually port/quota collisions — the LT-46 quota incident is the same *category* of \"worked in isolation, collided in combination\"). Enforcement site: the compose file's port mapping, or a documented override instructions if a fixed mapping is intentional.\n\n## Non-goals\n\n- No local Kubernetes (`kind`/`minikube`) — explicitly ruled out in `local-dev-loop.md`.\n- No CockroachDB profile locally — CI's dedicated job already covers that path; the local loop doesn't need every backend on every save, per the design doc's own reasoning.\n- No change to the production Dockerfile or CI pipeline — this story is additive, a new file plus small supporting pieces, not a modification to `containerization-design.md`/`ci-pipeline.md`.\n- No production credential handling review — dev credentials are explicitly out of `secrets-delivery.md`'s scope by design, not something this story needs to re-justify.\n\n## PO review script\n\n1. Read the committed `docker-compose.yml` directly against `local-dev-loop.md`'s sketch — confirm it matches (or note deliberate, sensible deviations), not a from-scratch reinterpretation.\n2. `docker compose --profile sqlite up` and `docker compose --profile postgres up` each independently, from a clean checkout with no prior `.dev-secrets/` — confirm no undocumented prerequisite blocks either from starting.\n3. Confirm `.dev-secrets/` is genuinely untracked (`git status` after `make dev-secrets-init` or equivalent) and appears in `.gitignore`.\n4. Confirm the `air`-based dev target is only reachable via a dev compose profile — read `cmd/api-service/Dockerfile` directly and confirm it's unmodified by this story's diff.\n5. Confirm the `postgres` profile's Postgres service either uses a non-default host port or the file documents the override for a developer who already has something on 5432.\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"

All four restated criteria match `backlog.md` Story 4 with no drift; the compose sketch details (DB_DRIVER wiring, secrets mechanism, air-scoping) trace correctly to `local-dev-loop.md`, not invented. One non-blocking note: `backlog.md`'s own AC3 enforcement text is stale, still describing the pre-F14-fix design (literal `dev`/`dev` env values) rather than the current `.dev-secrets/`-backed mechanism — flagged directly to Theo to fix in `backlog.md`, doesn't affect this refinement's own (correct, current) restatement. Grepped project-wide for other dev-loop references; none missed.\n\n**Tobias Lindqvist — objection:** Real gap, caught by actually reading the code, not just the prose: `local-dev-loop.md`'s \"Hot-reload\" section asserts \"one `air`-based dev target in the compose file,\" but the sketch's own YAML defines no such service — leaving the actual mechanism to be invented at implementation, with a plausible-but-wrong resolution available (adding a `dev` build stage to `cmd/api-service/Dockerfile` itself, which would leave the production target byte-identical but still touch the file this criterion's enforcement site says to leave alone — a check that would then fail even against a correct implementation, if \"unmodified\" were only eyeballed and not `git diff`'d). Also flagged that the `postgres` service has no named volume, so `docker compose down` silently drops dev data — cosmetic, not blocking, not added as a criterion. Fix applied: named the mechanism explicitly (`air` as its own separate compose service using an unmodified upstream image, source bind-mounted — never a Dockerfile build-stage variant), and sharpened the enforcement site to `git diff`, not a visual check.\n\n**Naomi Voss — ruling:** Fix applied. This refinement is accepted and ready to hand off. Tobias's catch here is a smaller instance of the same pattern this project keeps finding — a design doc's prose promises a mechanism its own example doesn't actually specify, leaving engineering to invent it, sometimes toward a plausible-looking wrong answer. Naming the mechanism explicitly in the refinement doc, rather than leaving it to be resolved at implementation time, is the fix worth repeating on future low-effort stories too — \"low effort\" describes the size of the gap, not its likelihood."

1	# Hand-off: what observability the cluster already has (LT-49, LT-20)
2	
3	**From:** Amber (OpenClaw Kubernetes agent on the Mac mini), read-only inventory on Warren's instruction, 2026-09-13 11:42–11:57 PDT. **Requested by:** Dana Whitfield (PM), after Warren asked "don't we already have a logging/monitoring/observability stack in the cluster?" **Receivers:** Theo Bergman (04) for the sink, alert rules, NetworkPolicy and RBAC; Renata Cole (03) for the `/metrics` exposure; Priya Nandakumar (05) for the sweep-result persistence contract; Naomi Voss (01) for the LT-49 and LT-20 refinement records; Marcus Ilori (02) for the audit-log residual.
4	
5	Amber's report follows verbatim. Names, versions, and namespaces only; nothing was created or changed.
6	
7	---
8	
9	## 1. What's actually here
10	
11	Both a Prometheus stack and an Elastic stack, from different eras and owned by different operators.
12	
13	| Component | Version | Namespace | Owner |
14	|---|---|---|---|
15	| kube-prometheus-stack operator | — | `monitoring` | Helm release `prometheus` |
16	| Prometheus | `v3.13.2-distroless` | `monitoring` | Prometheus Operator |
17	| Alertmanager | — | `monitoring` | Prometheus Operator |
18	| Grafana | `13.1.1` | `monitoring` | Helm |
19	| kube-state-metrics + node-exporter (DaemonSet, 5/5) | — | `monitoring` | Helm |
20	| ECK operator | — | `elastic-system` | ECK |
21	| Elasticsearch (CR `elastic`, 1 node, **yellow**) | `9.4.4` | `logging` | ECK |
22	| Kibana (CR `kibana`) | `9.4.4` | `logging` | ECK |
23	| Filebeat DaemonSet (5/5) | `9.4.4` | `logging` | **Helm, not ECK** |
24	
25	All `monitoring.coreos.com` CRDs are present: `prometheusrules`, `servicemonitors`, `podmonitors`, `scrapeconfigs`, `probes`, `alertmanagerconfigs`, `thanosrulers`.
26	
27	**No Loki. No Fluent Bit.** Note the Filebeat is *not* an ECK `Beat` CR (`kubectl get beat -A` → none); it's a Helm DaemonSet configured by ConfigMap `filebeat-filebeat-daemonset-config` in `logging`. Theo was right to ask before touching `logging`, but the shared object he'd have had to edit is that ConfigMap, not the ES/Kibana CRs.
28	
29	## 2. Yes — your stdout is already being collected
30	
31	Filebeat tails `/var/log/containers/*.log` on every node with no namespace allowlist, and adds `add_kubernetes_metadata`. Your lines land in the data stream:
32	
33	**`filebeat-9.4.4`** (backing indices `.ds-filebeat-9.4.4-YYYY.MM.DD-NNNNNN`, ~33M docs / 18.5 GB)
34	
35	I confirmed rather than assumed — `loginid-takehome` already has **2,643 documents**, including `db-migrate`, `postgres-0`, `lt46-injector-failure-test{,2,3}`, `lt44-review-2`. Filter field is `kubernetes.namespace`. So (a)'s *storage* problem is already solved and costs you nothing.
36	
37	**Two traps, both real:**
38	
39	- ⚠️ Filebeat has `drop_event` on regex `(kube-probe|health|/healthz|/readyz)` against `message`. Any metric line containing the substring **"health"** is silently discarded — `retention_sweep_health 1` would simply never appear, with no error anywhere. Name your metrics around that.
40	- ⚠️ **There is no per-namespace tenancy pattern.** 29 ES roles, all built-in — zero custom roles. Kibana has only the `default` space. You would be the first tenant, so there's no precedent to copy.
41	
42	## 3. Where alert rules live
43	
44	**Prometheus/Alertmanager. Not Kibana, not Grafana.**
45	
46	- 30+ `PrometheusRule` objects, all in `monitoring`, all from the Helm release.
47	- **Kibana alerting: 0 rules, 0 connectors.** Entirely unused — choosing it means building the rule engine *and* the notification path from scratch.
48	- Grafana has only Prometheus + Alertmanager datasources — **no Elasticsearch datasource**, so Grafana cannot query your logs today.
49	
50	**The house self-service mechanism exists and is permissive.** The Prometheus CR:
51	
52	```
53	ruleSelector            = {matchLabels: {release: prometheus}}
54	ruleNamespaceSelector   = {}        # empty = ALL namespaces
55	serviceMonitorSelector  = {matchLabels: {release: prometheus}}
56	serviceMonitorNamespaceSelector = {}
57	```
58	
59	So **a `PrometheusRule` or `ServiceMonitor` in `loginid-takehome` carrying the label `release: prometheus` is adopted automatically**, with no edit to any shared object. Prometheus's ClusterRole+ClusterRoleBinding already grant cluster-wide `get/list/watch` on pods/services/endpoints, so it can scrape you.
60	
61	Caveat I want to be straight about: all 13 existing ServiceMonitors are in `monitoring`. No tenant has used this path yet, so I'm verifying it from configuration, not from a working precedent.
62	
63	⚠️ **Alertmanager will silently eat your low-severity rule.** The route tree is:
64	
65	```
66	root receiver: discord    group_by: [namespace, alertname]
67	  ├─ alertname =~ Watchdog|InfoInhibitor  → null
68	  ├─ severity  =~ info|none               → null      ← dropped
69	  └─ severity  =  critical                → discord
70	  (no match → falls through to root → discord)
71	```
72	
73	`RetentionSweepSkipRate` at `severity: info` goes to the **null receiver and is never delivered**. Use `severity: warning` — it falls through to `discord`. `group_by` already includes `namespace`, so your alerts group separately from everyone else's.
74	
75	## 4. Recommendation
76	
77	**The blocking constraint: Prometheus cannot ingest stdout.** It scrapes HTTP endpoints. And a CronJob pod is short-lived, so even a PodMonitor would usually miss the run entirely. Pushgateway is the normal answer to exactly this and you've ruled it out — so the metrics need a different door.
78	
79	**(a) Export from the long-running pod, not from the CronJob.**
80	
81	Have the sweep persist its results to the database it already has access to (`db-runtime-credential`), and have **api-service** expose them on an HTTP `/metrics` port as gauges — `retention_sweep_last_success_timestamp_seconds`, `oldest_surviving_row_age_seconds`, `retention_sweep_skipped_total`. Then one `ServiceMonitor` in your namespace labelled `release: prometheus`.
82	
83	This isn't just a workaround — it's what makes rule (b)#1 *expressible*. "No fresh sample in > 2 intervals" becomes `time() - retention_sweep_last_success_timestamp_seconds > 2*interval`, which evaluates correctly **because an always-up pod serves the gauge**. If you instead alerted on the absence of a short-lived scrape target, you'd get an `absent()` that fires permanently and can never resolve.
84	
85	Keep printing to stdout as well — it's already captured in ES for free and gives you the forensic trail.
86	
87	⚠️ **NetworkPolicy will block the scrape.** `api-service-issuer`, `idp-connector` and `postgres` each have a default-deny ingress policy; none admits `monitoring`. (`api-service` currently has no policy, so it's reachable.) Whichever pod serves `/metrics` needs an ingress rule with `namespaceSelector: {kubernetes.io/metadata.name: monitoring}` — that label is auto-applied, so you select `monitoring` **without modifying it**. The policy object is yours, in your namespace.
88	
89	**(b)** One `PrometheusRule` — e.g. `loginid-takehome-retention` in ns `loginid-takehome`, label `release: prometheus`, all three rules in it. `warning` not `info` for the skip-rate rule.
90	
91	⚠️ **Your CI deployer cannot create either object yet.** `Role/loginid-takehome-deployer` grants `apps`, `""`, `networking.k8s.io`, `cert-manager.io`, `batch` — but **not `monitoring.coreos.com`**. Add that apiGroup with `prometheusrules`/`servicemonitors` to your own `deploy/rbac.yaml`. Namespaced Role, no shared object touched.
92	
93	**(c) This one does not fit the model, and I'd rather say so than dress it up.**
94	
95	The ES licence is **`basic`**. Document-level security is a Platinum/Enterprise feature, so **you cannot grant a filtered read over the shared `filebeat-9.4.4` stream restricted to `kubernetes.namespace: loginid-takehome`.** On Basic, index privileges are index-level only. Any role you create over `filebeat-9.4.4` grants the whole cluster's logs — every other tenant included.
96	
97	Two honest options:
98	
99	1. **Dedicated audit stream (recommended).** Have api-service write audit events to its own data stream (e.g. `loginid-takehome-audit-*`) rather than relying on stdout capture. Then an ES role granting `read` on just that pattern is genuinely scoped, with no DLS needed. The index is created by your app; only the role/user is a shared-stack object.
100	2. Accept namespace-wide log read on the shared stream — which I don't recommend for something labelled "audit".
101	
102	Either way, note that an ES role + user is a **cluster-level object in the shared Elastic stack**. It is not a Kubernetes object, it cannot live in your namespace, and your CI deployer cannot apply it. That's inherent, not a gap in your setup — so (c) will need an owner on the `logging` side regardless of which option you pick. (a) and (b) are fully self-contained; (c) isn't, and no amount of arranging will make it so on a Basic licence.

114	- **(a) and (b) proceed, self-contained in `loginid-takehome`.** The retention sweep persists its per-class results to the database it already reaches; `api-service` (the always-up pod) serves them as gauges on a separate `/metrics` port; one `ServiceMonitor` and one `PrometheusRule`, both labelled `release: prometheus`, both in our namespace; a NetworkPolicy ingress rule admitting `namespaceSelector: {kubernetes.io/metadata.name: monitoring}` on the metrics port only. Priya's three rules become Prometheus expressions over `time() - retention_sweep_last_success_timestamp_seconds`, per class. Severity `warning`, never `info`, for the skip-rate rule. No metric or label name may contain the substring `health` (Filebeat drops those lines silently).
115	- **The deployer Role needs `monitoring.coreos.com` (`prometheusrules`, `servicemonitors`).** That is a `deploy/rbac.yaml` change, bootstrap-applied, so it goes to Warren for the apply as before, and #62's preflight will now refuse to deploy until it is applied. Theo's PR states this in its body.
116	- **(c) does not fit on a Basic licence and is escalated to Warren**, not quietly closed: the two honest options are a dedicated audit data stream written by the application (then an index-level ES role that is genuinely scoped) or accepting namespace-wide read on the shared stream. Either needs a cluster-level ES role created by someone on the `logging` side. Recorded as an environment residual in the threat model until Warren rules.
117	- **LT-20 (log-sink retention) is now refinable**: the audit trail lives in the shared `filebeat-9.4.4` data stream, so retention is an ILM question on a shared object, and the story must say so.

1	# LT-49 refinement — S5: observability (logging, metrics, never-log enforcement, retention-sweep alerting)
2	
3	**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`.
4	
5	**Who did the work:** Refined by Naomi Voss (PO).
6	
7	## Why this one, now
8	
9	Per 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.
10	
11	## What this story actually is
12	
13	Not a redesign — `observability.md` already specifies every mechanism this story builds:
14	1. **Logging discipline + lint check** (04): explicit-field `slog` logging, a CI lint rule flagging never-log-list field names/whole-struct log calls.
15	2. **Ingress-level redaction** (04): search-endpoint `name`/`phone` query fragments never reach an ingress access log.
16	3. **Audit-log RBAC** (04): a distinct `Role` for audit-log read access, separate from any Secret-read grant.
17	4. **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).
18	5. **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.
19	
20	This 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).
21	
22	## Acceptance criteria (restated from `backlog.md` S5, split by side)
23	
24	**04 side:**
25	- [ ] 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.
26	- [ ] 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.
27	- [ ] 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.
28	- [ ] `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."
29	- [ ] 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.
30	- [ ] **Added per Tobias's objection:** the alert's suppression logic distinguishes a *skipped* run (LT-44's `concurrencyPolicy: Forbid` causing the next scheduled run to be skipped when the previous one is still active — itself required by LT-44 5a to be visible in observability) from a genuinely *dead* sweep. With `Forbid`, a skipped run means no new `oldest_surviving_row_age_seconds` line is emitted for that cycle at all — the alert reads the previous run's last value, and whether that's distinguishable from a truly stopped sweep depends on the sink's staleness/retention handling, which nothing in this story or LT-44 currently pins down. Enforcement site: either (a) the same alert rule additionally suppresses/qualifies on LT-44 5a's skip-visibility signal, or (b) a distinct alert exists for "sweep skipped, still healthy" vs. "sweep dead" — LT-44's own fix (Forbid + skip-visibility metric) must actually feed the one alert it was built to inform, not sit unused.
31	
32	**03 side:**
33	- [ ] 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).
34	- [ ] 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.
35	
36	**02 side:**
37	- [ ] Marcus (02) confirms in writing that `handoff-04-secrets.md`'s 11-item never-log list is fully covered by a named enforcement site. **Correction (Desmond's claims check):** `observability.md`'s "operationalized" section, as currently written, maps only items 1–9 ("hand-off's nine items map to two enforcement surfaces") — it predates the F50 consistency-pass fix that added items 10 (driver-error `DETAIL` text) and 11 (username) to the hand-off, and was never updated. Marcus's confirmation must therefore supply the missing mapping for items 10–11, not just cross-check an existing mapping that doesn't yet cover them. Flagged to Theo to update `observability.md` itself (source-doc drift, not this refinement's error to carry silently) — see note below.
38	
39	## Source-doc drift found during refinement (Desmond's claims check)
40	
41	Both traced to the same root cause: the F50 consistency-pass fix expanded `handoff-04-secrets.md`'s never-log list from nine items to eleven (items 10–11: driver-error `DETAIL` text, username), and that expansion was never back-propagated into two of 04's own documents:
42	- `observability.md`'s "operationalized" section still says "hand-off's nine items map to two enforcement surfaces" and only enumerates 1–9 — see the 02-side criterion above for the fix this requires.
43	- `04-infra-devops/backlog.md`'s own Story 5 (LT-49) acceptance-criteria text still says "handoff-04-secrets.md's nine items" — stale for the same reason. This refinement doc restates the criterion using the correct, current count (eleven) rather than perpetuating the stale number, but that means this refinement doc's wording will visibly disagree with `backlog.md`'s own text unless Theo corrects nine→eleven there too.
44	
45	Flagged to Theo (04) to fix both source documents directly, since they're his track's files — not something this refinement should silently carry forward or correct in his place.

  "new_string": "- [ ] **Audit-log read access, escalated to Warren, not closable by this track alone (Amber's read-only observability inventory, `handoff-amber-observability-inventory.md`):** the audit trail lives in the shared `filebeat-9.4.4` Elasticsearch data stream, and the ES licence is **Basic** — document-level security (the feature that would let a role read only `kubernetes.namespace: loginid-takehome`) is Platinum/Enterprise-only. Any ES role over `filebeat-9.4.4` grants read on **every tenant's** logs, not just this project's. Two honest options Amber named, neither closable inside this namespace: (a) write audit events to a dedicated data stream this application owns (e.g. `loginid-takehome-audit-*`), then an index-level ES role scoped to that pattern is genuinely narrow — the app creates the index, but the ES role/user itself is still a cluster-level object someone on the `logging` side must create, since this project's CI deployer has no path to create Elasticsearch objects at all; (b) accept namespace-wide read on the shared stream, which isn't real scoping for something labeled \"audit.\" Recorded as an environment residual in the threat model pending Warren's ruling, not silently closed as Done.\n- [ ] **Metrics sink — corrected per Amber's inventory, not what this refinement originally assumed.** Prometheus (the cluster's actual, only metrics sink — `kube-prometheus-stack` in ns `monitoring`) **cannot ingest a CronJob's stdout**; it only scrapes HTTP endpoints, and a short-lived Job pod would usually be gone before a scrape could catch it regardless. Mechanism (Amber's recommendation, Priya's addendum, PM's ruling): the sweep persists its per-class results to the database it already reaches; **`api-service`** (the one always-up pod) serves them as Prometheus gauges — `retention_sweep_last_success_timestamp_seconds`, `oldest_surviving_row_age_seconds{class}`, `retention_sweep_skipped_total` — on a separate `/metrics` port. **No metric or label name may contain the substring `health`** — Filebeat silently drops any log line matching `(kube-probe|health|/healthz|/readyz)`, so a metric name like `retention_sweep_health` would vanish with no error anywhere; this constraint is now binding on 03's naming choices, not just a nice-to-know. Enforcement site: a `ServiceMonitor` in `loginid-takehome`, labeled `release: prometheus` (the cluster's Prometheus CR selects on this label with an empty namespace selector — self-service, no edit to any shared object required) — confirmed scraping the real endpoint, not just present in a manifest.\n- [ ] **Alert rules — corrected mechanism, same three-rule design.** A `PrometheusRule` object (e.g. `loginid-takehome-retention`) in `loginid-takehome`, labeled `release: prometheus`, expressing Priya's three rules as real PromQL against the persisted-gauge metric above: `RetentionSweepNotReporting` as `time() - retention_sweep_last_success_timestamp_seconds{class=\"X\"} > 2*sweep_interval_seconds`, `RetentionWindowExceeded` as `oldest_surviving_row_age_seconds{class=\"X\"} > (W + 2*sweep_interval_seconds)`, `RetentionSweepSkipRate` on `retention_sweep_skipped_total`'s rate. **`RetentionSweepSkipRate` must be `severity: warning`, never `info`** — Alertmanager's route tree sends `severity =~ info|none` straight to a null receiver, so an `info`-severity rule would fire and be silently swallowed, never reaching Discord; this is now a hard requirement, not a style choice. Enforcement site: the `PrometheusRule` YAML's `labels.severity` field, plus a live check that the rule actually appears in Alertmanager (not just Prometheus) once fired.\n- [ ] **New NetworkPolicy requirement (Amber's inventory):** whichever pod serves `/metrics` (`api-service`) needs an ingress rule admitting `namespaceSelector: {kubernetes.io/metadata.name: monitoring}` on the metrics port specifically — Prometheus's scraper lives in a different namespace than every other consumer this project's NetworkPolicies were written for. `monitoring` is an auto-applied namespace label, so this is addressable without modifying the `monitoring` namespace itself.\n- [ ] **New RBAC requirement (Amber's inventory):** the CI deployer's `Role` (`deploy/rbac.yaml`) does not currently grant the `monitoring.coreos.com` API group at all — `prometheusrules`/`servicemonitors` must be added, namespaced to `loginid-takehome`, no shared object touched. This is a bootstrap-permission change (same class as the Vault-role RBAC additions in LT-46), so it goes to Warren for the apply, and deployment should refuse to proceed until it's applied rather than silently skip creating the new objects."

E.g., apply a throwaway `PrometheusRule` temporarily setting `RetentionWindowExceeded`'s threshold to `0` for one class, confirm the alert appears in Alertmanager (`kubectl port-forward` to the Alertmanager UI, or its API) carrying the `loginid-takehome` namespace label, then delete the throwaway rule and confirm the alert clears.

141	`oldest_surviving_row_age_seconds` is published **only from a `Drained` result** (`multi-db-strategy.md` §3c — the value is meaningless mid-sweep, when deletable rows remain by construction and the oldest survivor is old). So a sweep that runs but never drains — hitting `maxRows` every batch — emits **no valid sample**, and rule 1 fires.
142	
143	**That is correct behaviour, not a false positive.** A sweep that cannot drain is not keeping up, which is exactly what should alert. Do not "fix" it by publishing non-drained values: that would replace a true alert with a metric that reports a large age every run and trains everyone to ignore it.
144	
145	*Ruled by Priya Nandakumar (05 Data Ops lead). Retention windows from `05-data-ops/pii-governance.md`; `Drained` gating and the per-class sweep signature from `05-data-ops/multi-db-strategy.md` §3c. Question raised by Tobias Lindqvist (01); routed by team-lead.*
146	
147	## Update — implementation, 03 side (Renata Cole)
148	
149	**Real Prometheus client-library metrics, not log lines** — LT-44's original `StdoutMetricEmitter` (ad hoc `log.Printf` lines) is replaced by `internal/sweep.PrometheusMetricEmitter`: real `github.com/prometheus/client_golang/prometheus` `Gauge`/`GaugeVec` objects registered in their own private `prometheus.Registry`, satisfying this story's own criterion that these values reach an actual `prometheus.Client` registration. `rows_examined`, `rows_deleted`, `oldest_surviving_row_age_seconds{class}` keep their exact existing names/label values (agreed with Theo before opening this PR) — only `oldest_surviving_row_age_seconds` gated on `Drained == true`, unchanged from LT-44.
150	
151	**Exposition mechanism, agreed with Theo:** `PrometheusMetricEmitter.Render` writes the registry's current state to an `io.Writer` in real Prometheus text exposition format (via `github.com/prometheus/common/expfmt`) — `cmd/api-service`'s `runSweepMode` calls this once, after every class has been attempted, writing to the pod's own stdout. Stdout, not a Pushgateway push: confirmed with Theo there's no Pushgateway on the real cluster, and standing one up is disproportionate scope for this story — same disposition already reached for LT-44's original three metrics, now extended to cover the real client-library objects too. Theo's sink reads these lines via `kubectl logs` on the CronJob's last pod (PO review script territory), with Pushgateway named as the documented production next step.
152	
153	**New metric, `sweep_last_run_timestamp_seconds`** — a `Gauge` set unconditionally at the very start of every `Run()` invocation (via a new `MarkRunStarted(now time.Time)` method on the `MetricEmitter` interface, called before any class is attempted, regardless of whether a class later errors or the run is cancelled). Originally proposed to close Tobias's skip-visibility objection directly; **Priya's alert-formula ruling above superseded that plan** — her `RetentionSweepNotReporting` rule already gets the skip-vs-dead distinction from per-class staleness of `oldest_surviving_row_age_seconds` itself, deliberately property-based rather than mechanism-based, and is explicit that an alert consuming a "did a process start" signal is exactly the error her design avoids. **Confirmed with Theo (reconciling this before finalizing, not shipping in silent tension with Priya's ruling): `sweep_last_run_timestamp_seconds` is kept as a supplementary, kubectl-logs-level debugging signal only — deliberately not wired into any of the three alert rules.** It's still useful for a human diagnosing a specific incident (distinguishing "no process even started this cycle" from "a process started but errored before any class drained," a distinction neither of Priya's rules needs to fire correctly but that narrows root-causing once something has already fired).
154	
155	**Never-log-list enforcement test (03's other criterion):** `internal/api/neverlog_test.go` and `internal/connector/neverlog_test.go` — both redirect the standard library's package-level logger to a buffer and drive REAL request paths (the token-issuer's opportunistic-rehash-persist-failure branch with a distinctive client secret; a real search+get flow through the actual `StdoutAuditLogger` with seeded PII; the connector's `/auth`/`/identity` handlers across all their outcomes with a distinctive vendor username/password/access-token) rather than asserting against the log-call source text the way 04's static CI lint check does. Verified each test can actually fail: injected a real leak into `tokenhandler.go`'s rehash-failure log line, confirmed the test caught it, reverted. Covers never-log-list items 1, 2, 3, 6, and 11 (`handoff-04-secrets.md`'s eleven-item list) at the application layer; items 4, 7, 8, 9, 10 are either DAO/ingress-layer concerns already covered elsewhere or not exercised by a real call site in this track's own code.

Live-verified: ran the actual `api-service` binary with `APP_MODE=sweep` against a real throwaway Postgres, confirmed the rendered stdout output is genuine, parseable Prometheus text exposition format with the correct metric names and values.\n\n## Correction — mechanism superseded by Amber's observability inventory (not this work wasted, redirected)\n\n**The stdout-exposition mechanism above (§147–157) cannot be the final sink — Prometheus does not ingest stdout at all**, and a `CronJob` pod is typically gone before any scrape could catch it regardless. This was a reasonable assumption at the time (no Pushgateway on the cluster, and stdout was already this project's working pattern for LT-44's original metrics) but Amber's read-only inventory (`handoff-amber-observability-inventory.md`, requested after Warren asked whether the cluster already had an observability stack) confirmed the real constraint directly against the live Prometheus CR rather than assuming one didn't exist.\n\n**Not wasted work — most of it carries forward directly:** the real `prometheus.Gauge`/`GaugeVec` objects, the exact metric names/label values, the `Drained`-gating, and the never-log-list enforcement tests are all unaffected and still correct. **What changes:** `PrometheusMetricEmitter.Render`'s destination. Instead of writing to the sweep pod's own stdout (unreachable by any scraper), the sweep must persist its per-class `SweepResult` to the database (Priya's addendum, per the corrected 03-side criterion above), and `api-service` — the one always-up pod — reads that persisted state and serves it on its own `/metrics` HTTP port for a `ServiceMonitor` to scrape. `sweep_last_run_timestamp_seconds` carries forward as the persisted \"last success\" gauge Amber's rule 1 formula needs (`time() - retention_sweep_last_success_timestamp_seconds > 2*interval`) — no longer just a supplementary debugging signal, now load-bearing for the corrected alert mechanism.\n\n**Also binding now, not previously known:** no metric or label name may contain the substring `health` (Filebeat silently drops matching log lines) — checked the existing metric names above (`rows_examined`, `rows_deleted`, `oldest_surviving_row_age_seconds`, `sweep_last_run_timestamp_seconds`) against this constraint: none contain it, so no rename is needed, but this is now a standing naming constraint for any future metric this project adds, not just today's set.\n\nFlagged to Renata and Theo directly — this refinement doc's own acceptance criteria (04 side, metrics-sink and alert-rule entries above) already reflect the corrected mechanism; the code needs to catch up to match.\n\n---"

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).

124-## Story 7 — Database provisioning in-namespace: Postgres, DB credentials Secret, migration Job, DB_DSN_FILE wiring (LT-52)
--
126:**Status: new** — created from a gap found during 01's LT-40 refinement (`03-engineering-delivery/refinement/LT-40.md`): none of this track's existing stories (LT-45/46/47/48/49/LT-20) actually deploy a running database instance into `loginid-takehome` — they all assume a DB target already exists. Without it, LT-39's handlers have nothing real behind the DAO, and LT-34/LT-39/LT-40/LT-51's joint live-URL review can't exercise a genuine data path. Full refinement: `04-infra-devops/refinement/postgres-in-namespace.md`.
127-
128-**Description:** A single-replica PostgreSQL `StatefulSet` (with a `PersistentVolumeClaim`) in `loginid-takehome` — a managed instance would be disproportionate infra/cost for this take-home's scale, and a single `StatefulSet` matches this project's existing "small, isolated, no HA beyond what's needed" pattern (Theo's call, confirmed). Plus: a DB credential `Secret` provisioned out-of-band per the pattern already established for the JWT signing key (`deploy/issuer-secret-bootstrap.yaml`); the two-invocation goose migration `Job` in the corrected order (backend directory first, then `shared/`, per `05-data-ops/migration-approach.md`'s own corrected ordering); and `DB_DSN_FILE` wiring so `api-service` actually connects. **CockroachDB is explicitly out of scope for deployment** — it's exercised in CI only (LT-47's testcontainer job), never deployed live in this cluster; stated here so a reviewer doesn't expect to find it running.
129-
130-**Acceptance criteria:**
131-- [ ] Single-replica PostgreSQL `StatefulSet` + `PersistentVolumeClaim` running in `loginid-takehome`.
132-- [ ] A default-deny `NetworkPolicy` scopes Postgres's ingress to `api-service` (and the migration `Job`'s pod) only — matching `idp-connector-default-deny`'s existing shape, not the namespace's default-allow.
133-- [ ] DB credential `Secret` provisioned out-of-band, never through the CI-applied manifest set — same discipline as the JWT signing key.

  "content": "# LT-20 refinement — S6: log-sink retention for the audit trail\n\n**Product Owner:** Naomi Voss (01). **Research team:** Desmond Okafor (claims check), Tobias Lindqvist (objection seat). **Engineering:** Theo Bergman (04). **Design inputs:** Marcus Ilori (02, never-log-list scope), Priya Nandakumar (05, retention-window row), Amber (read-only observability inventory). **Source:** `04-infra-devops/backlog.md` Story 6 (LT-20), corrected against `04-infra-devops/handoff-amber-observability-inventory.md`.\n\n**Who did the work:** Refined by Naomi Voss (PO).\n\n## Why this refinement corrects the backlog's own framing before restating criteria\n\n`backlog.md`'s Story 6 description names the enforcement site as \"a retention policy on the log sink 04 already operates (Loki or equivalent)\" and its own acceptance criteria assume this track can simply \"configure the sink's retention setting to that window.\" **Both assumptions are wrong, confirmed by Amber's read-only inventory, not assumed correct at design time:**\n\n- **There is no Loki.** The cluster runs Filebeat (Helm DaemonSet, not an ECK `Beat` CR) shipping every namespace's stdout — this project's included, already, at no cost to us — into a single shared Elasticsearch data stream, `filebeat-9.4.4`, owned by the `logging` namespace's operators, not by this track.\n- **04 does not operate this sink.** `filebeat-9.4.4` is configured by a ConfigMap (`filebeat-filebeat-daemonset-config`) and backed by an Elasticsearch cluster this project's CI deployer has zero access to — no Kubernetes RBAC grant reaches Elasticsearch's own object model at all (an ES index-lifecycle-management, ILM, policy is a cluster-level object in a different system, not a Kubernetes CRD this namespace's `Role` could ever cover).\n- **The retention window can't be scoped to just this project's data even in principle, on the license the cluster runs.** The ES license is **Basic** — document-level security (the feature that would let an ILM/retention policy or a read scope apply to only `kubernetes.namespace: loginid-takehome` within the shared stream) is a Platinum/Enterprise feature. Any retention policy applied to `filebeat-9.4.4` is index/stream-level, meaning it would apply to **every tenant's logs in that stream**, not just this project's audit trail.\n\nThis means Story 6 as originally scoped — \"this story configures the sink's retention setting to that window once it's a number\" — describes an action this track cannot actually take, on infrastructure this track does not own, at a granularity the platform's own license doesn't support. Per the PM's routing: **this story's job is to say what retention it needs and who applies it, not to pretend this namespace can apply it itself.**\n\n## What this story actually is, corrected\n\nNot a configuration change 04 makes. Instead:\n1. **State the required retention window precisely**, sourced from 05's `pii-governance.md` audit-log row (still pending a legal ruling on the actual number, per the original story's own \"basis: unknown\" framing — unaffected by this correction).\n2. **Name the actual owner who must apply it**: whoever administers the shared Elastic stack in `logging` — outside this project's org boundary, the same class of escalation as LT-49's audit-log-RBAC item (both trace to the same Basic-license constraint, on the same shared stream).\n3. **Record the options honestly, mirroring LT-49's audit-RBAC framing** (Amber's inventory named this once and both stories inherit it):\n   - **Option A (recommended, matches LT-49's audit-RBAC recommendation):** if `api-service` is changed to write audit events to its own dedicated data stream (e.g. `loginid-takehome-audit-*`, per LT-49's audit-RBAC option (a)) rather than relying on Filebeat's stdout capture of the shared stream, then an ILM policy scoped to that dedicated stream **is** genuinely this project's own object to request — narrow, not touching any other tenant's retention. This makes LT-20 and LT-49's audit-RBAC item the same underlying architectural decision, not two independent asks to the `logging` owner.\n   - **Option B:** accept that the audit trail's retention rides on whatever retention policy already exists (or doesn't) for the shared `filebeat-9.4.4` stream — meaning this project's audit data expires exactly when everyone else's does, decided by someone else's policy, with no ability to set or verify a project-specific window at all.\n4. **This story cannot be called Done by a configuration change in this namespace.** It's Done when the required window is stated, the owner is named and asked, and (if Option A is chosen) the dedicated-stream decision is recorded as a joint scope with LT-49's audit-RBAC item — or when whoever owns `logging` rules on Option B and this project accepts that ruling explicitly rather than by default.\n\n## Acceptance criteria (corrected from `backlog.md` S6)\n\n- [ ] The hand-off standard holds: 02's never-log-list scope and 05's retention-window row are each confirmed independently, without this story needing to be rewritten if either changes later — unaffected by this correction.\n- [ ] **Corrected:** the required retention window is stated precisely (05's `pii-governance.md` row, once ruled), and the request to apply it is sent to the actual owner (whoever administers the shared Elastic stack in `logging`) — not configured directly, since this track has no access to do so.\n- [ ] **Corrected:** if Option A (dedicated audit data stream) is adopted — jointly with LT-49's audit-RBAC decision, since both are the same underlying architectural question — the ILM policy request is scoped to that dedicated stream by name, never the shared `filebeat-9.4.4` stream as a whole.\n- [ ] Confirmed this remains a configuration/request, not a deletion job: no new DAO method, no new `cmd/` entrypoint, no scheduled job beyond LT-49's retention-sweep story for `user_profile`/`user_credential`-derived data — unaffected by this correction, restated for clarity since the enforcement site moved outside this namespace.\n- [ ] **Added:** this story is not marked Done on a configuration value this track can't actually verify was applied — the closing check is a request sent and a response received (or an explicit acceptance of Option B), not \"we set a number in our own manifest,\" since no such manifest exists for this track to set it in.\n\n## Non-goals\n\n- No new retention windows invented by this track — 05's number, once ruled, is the number requested.\n- No attempt to build a per-namespace log-sink from scratch (a dedicated Loki instance, e.g.) to route around the shared stream's limitation — that's new, disproportionate infrastructure for a take-home, and duplicates infrastructure the cluster already has (same reasoning `local-dev-loop.md` used to rule out a local Kubernetes cluster).\n- No re-litigation of the never-log list's scope — 02's list, already final, is assumed correct here.\n\n## PO review script\n\n1. Confirm 05's `pii-governance.md` states the audit-log retention window as a ruled number (not still \"basis: unknown\") before this story can close — if still unruled, this story stays open on that dependency alone, same as it always has.\n2. Confirm a request was actually sent to the `logging` stack's owner (an email, a ticket, a message — whatever channel exists) naming the specific window and the specific stream (dedicated, if Option A; shared, if Option B) — not just recorded as an intention in this doc.\n3. If Option A: confirm this is the same decision as LT-49's audit-RBAC item, not a second, redundant request to the same owner for a subtly different scope.\n4. Confirm the response (or the explicit acceptance of Option B, with no response needed) is recorded before Done — a request sent with no confirmed outcome is not the same as a closed loop.\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"

Both are based directly on `04-infra-devops/handoff-amber-observability-inventory.md` — Amber's read-only inventory of what observability infrastructure the cluster actually has (kube-prometheus-stack in ns monitoring; a shared Elasticsearch/Filebeat stack in ns logging on a Basic license with no per-namespace scoping; specific traps: Filebeat drops any log line matching the substring \"health\"; Alertmanager routes severity=info to a null receiver; Prometheus can't ingest CronJob stdout, needs a ServiceMonitor scrape target instead).\n\nRead all three files (LT-49.md, LT-20.md, the Amber handoff) and verify:\n1. Every specific claim in LT-49.md's new/corrected criteria (the metrics-sink mechanism, the NetworkPolicy requirement, the RBAC requirement, the audit-log-RBAC escalation, the \"health\" substring trap, the info-severity trap) is accurately quoted/summarized from the Amber handoff — not embellished or misstated.\n2. LT-20.md's claims about the shared filebeat-9.4.4 stream, the Basic license/no-DLS constraint, and the \"Option A / Option B\" framing are accurate against the same handoff, and consistent with what LT-49.md says about the same underlying constraint (they should describe the same Basic-license/DLS limitation the same way, not contradict each other).\n3. Whether LT-49.md's existing \"Update — implementation, 03 side (Renata Cole)\" section (the stdout-based PrometheusMetricEmitter work) is now correctly flagged as superseded by the new \"Correction\" section that follows it — check that the correction accurately describes what carries forward vs. what changes, against the actual prior implementation section's text.\n\nReport PASS or specific discrepancies (quote the doc's claim and the source text that contradicts it) for each of the 3 areas.

This project's standing pattern has been catching real gaps (unenforced config, missing fail-loud behavior, concurrency races, mechanism assumptions that turn out wrong once actually checked) — look for the next one, not a style nit. Specifically worth checking:\n\n1. LT-49's new alert rules reference `retention_sweep_skipped_total` as a counter Renata's implementation needs to add — but the existing \"Update — implementation, 03 side\" section (further down the same file) only describes `rows_examined`/`rows_deleted`/`oldest_surviving_row_age_seconds`/`sweep_last_run_timestamp_seconds`. Is `retention_sweep_skipped_total` actually specified anywhere as something the sweep or the CronJob's own skip-visibility signal (LT-44 5a) actually produces, or is this a metric name invented in the alert-rule section with no corresponding emission criterion anywhere in this doc?\n2. LT-20 proposes \"Option A\" (a dedicated `loginid-takehome-audit-*` data stream) as the same underlying decision as LT-49's audit-RBAC item — but is anything in either doc actually the RIGHT owner/mechanism to decide that, or does this refinement just assert the two are \"the same decision\" without anyone with authority over either the audit-log design (Marcus/02) or the ES stack (logging owner) actually agreeing that's true? Could treating them as one decision accidentally under-scope one of the two stories?\n3. The PO-script's new step 9 (fire one alert on purpose via a throwaway PrometheusRule) — does it specify how the threshold-0 rule interacts with the REAL PrometheusRule already running for the same class/alertname? Could a throwaway rule with the same alertname collide with or get deduplicated against the real one in Alertmanager, making the \"confirm it clears after deletion\" check ambiguous about which rule actually fired?\n4. Anything else concrete you find.\n\nGive your strongest objection(s) as specific, concrete gaps — not vague \"consider\" notes. If you genuinely find nothing beyond what's already handled, say so.
