"description": "Find the stale activeDeadlineSeconds note"
}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.
123:- On failure, `classifySweepDBConnectError` names the failure class (`connect_timeout`/`connection_refused`/`dns_error`/`unknown`) in one structured log line, and the process exits non-zero immediately — the Job fails fast and frees the `concurrencyPolicy: Forbid` slot for the next scheduled run, instead of occupying it for the CronJob's full `activeDeadlineSeconds`.
126:**Coordination with Theo (04), checked directly against the actual manifest, not assumed:** `deploy/manifests.yaml`'s CronJob currently sets `startingDeadlineSeconds: 900` (how long a *skipped* tick waits before Kubernetes gives up scheduling it) but has **no `activeDeadlineSeconds`** at all — the PR #57 diff's own comment says so explicitly ("No backoffLimit override... and no explicit activeDeadlineSeconds — a stuck sweep should retry like any other Job"). That means my 20s inner connect-timeout has no explicit outer bound to coordinate with yet; without it, a pod stuck for some OTHER reason past the connect check (not this fix's concern, but worth naming) could run until `backoffLimit` retries are exhausted rather than being bounded by a stated wall-clock ceiling. Flagging to Theo: either add an explicit `activeDeadlineSeconds` comfortably larger than 20s plus the sweep's own expected run time, or confirm the retry-based bound (`backoffLimit: 6`, the default) is the deliberate design and this doc's framing should say so instead. Not blocking this PR — the connect-timeout fix stands on its own regardless of what the outer bound turns out to be.

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.

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.{

116 ## Update — fail-loud on unreachable database (Renata Cole, 03)
117
118 **Naomi's live run of the sweep CronJob found the pod sitting `Running` for minutes with one socket in `SYN_SENT` to Postgres (a NetworkPolicy omission, Theo's own fix) and never logging anything at all** — two minutes of silence cost real diagnosis time. Root cause on 03's side: `dao.New`/`sql.Open` never dial (they only validate the driver/DSN), so nothing bounded the first *actual* connection attempt, which happened inside `sweep.Run`'s own first `DeleteExpired` call, using a context derived only from `signal.NotifyContext` (SIGTERM/SIGINT, no deadline of its own) — a genuinely unreachable database meant an unbounded hang, not a fast failure.
119
120 **Fixed in `cmd/api-service/main.go`'s `runSweepMode`:**
121 - A startup log line (`"api-service: sweep starting, classes=..., interval_seconds=..."`) now fires before anything touches the database at all — an operator watching pod logs sees the process reached the DB step immediately, not two minutes of silence.
122 - A bounded connectivity check (`sweepDBConnectTimeout = 20s`, the middle of the requested 10–30s range) runs via a dedicated `*sql.DB.PingContext`, before `sweep.Run` is ever called — a separate handle from `repo` since `dao.Repository` exposes no `Ping` (05's contract doesn't have one), mirroring the same pattern the verifier's `/healthz` probe already uses.
123 - On failure, `classifySweepDBConnectError` names the failure class (`connect_timeout`/`connection_refused`/`dns_error`/`unknown`) in one structured log line, and the process exits non-zero immediately — the Job fails fast and frees the `concurrencyPolicy: Forbid` slot for the next scheduled run, instead of occupying it for the CronJob's full `activeDeadlineSeconds`.
124 - New `SWEEP_INTERVAL_SECONDS` env var (purely descriptive, classified in `config.OptionalEnvVars`) — echoes the CronJob's own schedule in the startup log line so an operator doesn't have to cross-reference the manifest separately; never read by `internal/sweep`'s own logic.
125
126 **Coordination with Theo (04), checked directly against the actual manifest, not assumed:** `deploy/manifests.yaml`'s CronJob currently sets `startingDeadlineSeconds: 900` (how long a *skipped* tick waits before Kubernetes gives up scheduling it) but has **no `activeDeadlineSeconds`** at all — the PR #57 diff's own comment says so explicitly ("No backoffLimit override... and no explicit activeDeadlineSeconds — a stuck sweep should retry like any other Job"). That means my 20s inner connect-timeout has no explicit outer bound to coordinate with yet; without it, a pod stuck for some OTHER reason past the connect check (not this fix's concern, but worth naming) could run until `backoffLimit` retries are exhausted rather than being bounded by a stated wall-clock ceiling. Flagging to Theo: either add an explicit `activeDeadlineSeconds` comfortably larger than 20s plus the sweep's own expected run time, or confirm the retry-based bound (`backoffLimit: 6`, the default) is the deliberate design and this doc's framing should say so instead. Not blocking this PR — the connect-timeout fix stands on its own regardless of what the outer bound turns out to be.
127
128 **Live-verified, not just unit-tested:** ran the real binary against a genuinely unreachable database (a non-routable IP) — confirmed the startup line appears immediately, the process fails loud at exactly 20s with `class=connect_timeout`, and exits non-zero. Re-ran against a real reachable Postgres to confirm no regression to the happy path. `TestClassifySweepDBConnectError` covers the classifier directly; `TestLoad_SweepIntervalSeconds` covers the new config field. Full `go build`/`go vet`/`go test`/`staticcheck`/`gofmt`/`gitleaks` clean.

# Hand-off: what observability the cluster already has (LT-49, LT-20)
**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.
Amber's report follows verbatim. Names, versions, and namespaces only; nothing was created or changed.

## 1. What's actually here
Both a Prometheus stack and an Elastic stack, from different eras and owned by different operators.
| Component | Version | Namespace | Owner |
|---|---|---|---|
| kube-prometheus-stack operator | — | `monitoring` | Helm release `prometheus` |
| Prometheus | `v3.13.2-distroless` | `monitoring` | Prometheus Operator |
| Alertmanager | — | `monitoring` | Prometheus Operator |
| Grafana | `13.1.1` | `monitoring` | Helm |
| kube-state-metrics + node-exporter (DaemonSet, 5/5) | — | `monitoring` | Helm |
| ECK operator | — | `elastic-system` | ECK |
| Elasticsearch (CR `elastic`, 1 node, **yellow**) | `9.4.4` | `logging` | ECK |
| Kibana (CR `kibana`) | `9.4.4` | `logging` | ECK |
| Filebeat DaemonSet (5/5) | `9.4.4` | `logging` | **Helm, not ECK** |
All `monitoring.coreos.com` CRDs are present: `prometheusrules`, `servicemonitors`, `podmonitors`, `scrapeconfigs`, `probes`, `alertmanagerconfigs`, `thanosrulers`.
**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.
## 2. Yes — your stdout is already being collected
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:
**`filebeat-9.4.4`** (backing indices `.ds-filebeat-9.4.4-YYYY.MM.DD-NNNNNN`, ~33M docs / 18.5 GB)
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.
**Two traps, both real:**
- ⚠️ 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.
- ⚠️ **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.
## 3. Where alert rules live
**Prometheus/Alertmanager. Not Kibana, not Grafana.**
- 30+ `PrometheusRule` objects, all in `monitoring`, all from the Helm release.
- **Kibana alerting: 0 rules, 0 connectors.** Entirely unused — choosing it means building the rule engine *and* the notification path from scratch.
- Grafana has only Prometheus + Alertmanager datasources — **no Elasticsearch datasource**, so Grafana cannot query your logs today.
**The house self-service mechanism exists and is permissive.** The Prometheus CR:
```
ruleSelector = {matchLabels: {release: prometheus}}
ruleNamespaceSelector = {} # empty = ALL namespaces
serviceMonitorSelector = {matchLabels: {release: prometheus}}
serviceMonitorNamespaceSelector = {}
```
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.
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.
⚠️ **Alertmanager will silently eat your low-severity rule.** The route tree is:
```
root receiver: discord group_by: [namespace, alertname]
├─ alertname =~ Watchdog|InfoInhibitor → null
├─ severity =~ info|none → null ← dropped
└─ severity = critical → discord
(no match → falls through to root → discord)
```
`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.
## 4. Recommendation
**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.
**(a) Export from the long-running pod, not from the CronJob.**
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`.
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.
Keep printing to stdout as well — it's already captured in ES for free and gives you the forensic trail.
⚠️ **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.
**(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.
⚠️ **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.
**(c) This one does not fit the model, and I'd rather say so than dress it up.**
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.
Two honest options:
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.
2. Accept namespace-wide log read on the shared stream — which I don't recommend for something labelled "audit".
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.
<details>
<summary>What I touched (nothing)</summary>
Read-only throughout: `kubectl get/describe`, and read-only GETs against the ES and Kibana APIs via temporary port-forwards using the ECK-generated `elastic` user. No objects created, modified, or deleted; both port-forwards closed; no credential reproduced here or written to any file.
</details>

## PM rulings from this report (Dana, 12:00 PDT)
- **(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).
- **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.
- **(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.
- **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.{

Metric names: retention_sweep_last_success_timestamp_seconds{class}, oldest_surviving_row_age_seconds{class} (unchanged name/Drained-only rule from LT-44/49), retention_sweep_skipped_total{class}, rows_examined{class}, rows_deleted{class} — none contain \"health\" per Amber's Filebeat-drop finding.",

}## 3d. `retention_sweep_run` — the sweep's result, persisted (amendment A7) Added because the retention alerts run in the cluster's Prometheus, which scrapes an HTTP endpoint on the always-up `api-service` rather than reading the `CronJob`'s stdout (`../04-infra-devops/handoff-amber-observability-inventory.md`). The sweep is a short-lived pod; the scraper is a long-lived one; they never overlap. **So the sweep's per-class result has to live somewhere `api-service` can read it, and that somewhere is a table.** ``` retention_sweep_run id UUID PK class TEXT NOT NULL ck_retention_sweep_run_class: 'direct'|'idp_cache'|'idp_cache_orphan' started_at TIMESTAMPTZ NOT NULL finished_at TIMESTAMPTZ NULL -- NULL = started and did not finish rows_examined INTEGER NOT NULL DEFAULT 0 rows_deleted INTEGER NOT NULL DEFAULT 0 oldest_surviving_at TIMESTAMPTZ NULL -- non-NULL only when drained drained BOOLEAN NOT NULL DEFAULT false missed_slots INTEGER NOT NULL DEFAULT 0 ``` **Written twice per run, not once.** A row is inserted at start (`finished_at` NULL) and updated at completion. That is deliberate: it makes three outcomes distinguishable that would otherwise collapse. **No row** = the run never started (skipped by `concurrencyPolicy: Forbid`, or the schedule is dead). **Row with NULL `finished_at`** = it started and died. **Row with `finished_at`** = it completed. Writing only on success would make a crashing sweep indistinguishable from one that was never scheduled — the same three-states-in-one-null defect `secret_state` exists to prevent. **`skipped_reason` cannot be a column, and this is the one place the requested shape does not work.** Under `Forbid`, a skipped run **has no pod** — nothing executes, so nothing can write a row explaining itself. A `skipped_reason TEXT NULL` would be NULL on every row that exists, forever. Skips are therefore recorded by the *next* run rather than the skipped one: on start, the sweep compares the gap since the last `finished_at` for that class against the interval `I` and writes **`missed_slots`** — `floor(gap / I) - 1`, zero in the normal case. That makes the skip rate computable from this table alone (`sum(missed_slots)` over a rolling day against expected runs), which is what `RetentionSweepSkipRate` needs, without depending on Kubernetes event scraping. **Tying CHECK, named `ck_retention_sweep_run_drained`:** `CHECK (drained OR oldest_surviving_at IS NULL)`. `oldest_surviving_at` is meaningful only from a drained result (§3c), so a non-drained row carrying one must be **unrepresentable, not merely discouraged**. NULL *with* `drained` stays legal — that is an empty class, which is a real state. **Index** `(class, finished_at DESC)` — serves both reads: latest-per-class for the gauges, and the rolling-day scan for the skip rate. **Roles: no new grant.** The sweep writes and `api-service` reads, both with the existing **runtime** credential. All four operations are DML, and `ALTER DEFAULT PRIVILEGES FOR ROLE migrator … GRANT SELECT, INSERT, UPDATE, DELETE ON TABLES TO runtime` already covers tables the migrator creates from that point on — which includes this one, since the migration runs as migrator. Nothing in `04`'s initdb changes. **Migrations: three files, not `shared/`.** This is DDL, so it goes in `postgres/`, `cockroachdb/` and `sqlite/` per A5 — `shared/` is seed data only. Same per-engine type mapping as every other table (`TIMESTAMPTZ` vs `TEXT` RFC3339, `BOOLEAN` vs `INTEGER`), and identical constraint names across all three. **This table's own retention — it is not a `RetentionClass`.** It holds operational metadata and no PII, so it is outside `pii-governance.md` and acquires no retention clock there. But it must not grow without bound: the sweep deletes `retention_sweep_run` rows older than **30 days** at the end of each run. Thirty days comfortably covers the widest alert window (24h) and leaves a month of history for debugging; at three classes daily that is roughly 90 rows. Two things that must not happen to it. **It must never be added as a fourth `RetentionClass`** — the classes are `user_profile` classes, and mixing operational metadata into the PII retention machinery would put a table with no data subject under a policy built for people. And **its cleanup must never write a `deletion_log` row** — that log is the audit trail for *PII* deletions with meaningful reason codes, and diluting it with routine metadata housekeeping would make the thing auditors read mostly noise. ### Conformance assertions (§7) — three backends
