If you wish to stick to the legacy name validation use `IsValidLegacyMetricName()` and `LabelName.IsValidLegacy()` methods instead. This variable is here as an escape hatch for emergency cases, given the recent change from `LegacyValidation` to `UTF8Validation`, e.g., to delay UTF-8 migrations in time or aid in debugging unforeseen results of the change. In such a case, a temporary assignment to `LegacyValidation` value in the `init()` function in your main.go or so, could be considered. (SA1019)

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).

| Class | W | Rule 2 threshold (W + 2I) | Seconds |
|---|---|---|---|
| `idp_cache_orphan` | 7 days | 9 days | 777600 |
| `idp_cache` | 30 days | 32 days | 2764800 |
| `direct` | 24 months (730d) | 732 days | 63244800 |

Rule 1 threshold is **2I = 172800 s** for every class.

**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.

### One interaction that must not be "fixed"

`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.

**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.

*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.*

47:## Priya's seat — retention-alert threshold
78:## Priya Nandakumar's ruling — the alert formula (05)
## Priya Nandakumar's ruling — the alert formula (05)

**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.

### Why suppression-on-skip is the dangerous option

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.

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."

### The three rules

Let **W** = the class's retention window, **I** = the CronJob interval, **D** = a sweep run's duration.

**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 (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.

**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.

**2. `RetentionWindowExceeded` — per class.** Fires when `oldest_surviving_row_age_seconds{class} > W + 2I`.

**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.

**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.

### Numbers, at I = 24h

Theo substitutes the real interval; these are the values if the CronJob is daily.

| Class | W | Rule 2 threshold (W + 2I) | Seconds |
|---|---|---|---|
| `idp_cache_orphan` | 7 days | 9 days | 777600 |

  "message": "Just read Priya's alert-formula ruling in refinement/LT-49.md (posted after we agreed on sweep_last_run_timestamp_seconds). Her Rule 1 (RetentionSweepNotReporting) gets the skip-vs-dead distinction purely from staleness of the EXISTING oldest_surviving_row_age_seconds{class} metric — no fresh sample in >2I fires, regardless of whether the gap is a single Forbid-skip or a genuinely dead sweep — and she's explicit that suppressing on a skip signal is \"the same error\" as alerting on the mechanism rather than the property.\n\nThat makes my sweep_last_run_timestamp_seconds heartbeat gauge partially redundant with what her Rule 1 already achieves, and possibly in tension with her stated philosophy (a mechanism-level \"did a process start\" signal vs. her property-level \"is this class still reporting\"). I've already implemented it (real Gauge, unconditional at run start) since we agreed on it before her ruling posted, and it's genuinely useful operationally (distinguishes \"sweep never started\" from \"sweep started but errored before any class drained,\" which Rule 1 alone treats identically — both look like a missing sample).\n\nQuestion: keep it as a supplementary metric (doesn't feed her three alert rules, just available for manual debugging/kubectl-logs inspection), or drop it since her ruling makes the alerting design self-sufficient without it? I lean toward keeping it (cheap, doesn't conflict with anything, useful signal beyond just alerting) but want your read before I finalize the PR, since you're the one wiring the actual alert rules and I don't want to ship something that muddies her design.",

Question raised by Tobias Lindqvist (01); routed by team-lead.*\n\n## Update — implementation, 03 side (Renata Cole)\n\n**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.\n\n**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.\n\n**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).\n\n**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.\n\nFull `go build`/`go vet`/`go test`/`staticcheck`/`gofmt`/`gitleaks` clean. 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---\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); Priya Nandakumar (05, alert-formula ruling); Renata Cole (03, metrics-exposure implementation + never-log enforcement tests); Theo Bergman (04, metric-name/mechanism agreement)."

Theo's side (lint check, ingress redaction, audit-log RBAC, sink, alert rules) is a separate PR. Metric names/mechanism agreed with Theo by message before opening this PR.\n\n**Metrics exposure:**\n- `internal/sweep.PrometheusMetricEmitter` replaces LT-44's original `StdoutMetricEmitter` (ad hoc `log.Printf` lines) with real `github.com/prometheus/client_golang` `Gauge`/`GaugeVec` objects in their own `prometheus.Registry` — the criterion that these values reach an actual `prometheus.Client` registration, not just a log line.\n- `rows_examined`, `rows_deleted`, `oldest_surviving_row_age_seconds{class}` keep their exact existing names/labels; only the last stays gated on `Drained == true`.\n- `Render` writes the registry to real Prometheus text exposition format (via `github.com/prometheus/common/expfmt`) to the pod's stdout — agreed mechanism with Theo (no Pushgateway on the real cluster, disproportionate scope for this story).\n- New `sweep_last_run_timestamp_seconds` heartbeat gauge (`MetricEmitter.MarkRunStarted`, unconditional at run start). Originally proposed to close Tobias's skip-visibility objection; **Priya's later alert-formula ruling superseded that plan** (her `RetentionSweepNotReporting` rule gets the skip-vs-dead distinction from per-class metric staleness, deliberately property-based). Reconciled with Theo: kept as a supplementary, kubectl-logs-only debugging signal, deliberately not wired into any alert rule.\n\n**Never-log-list enforcement tests** (`internal/api/neverlog_test.go`, `internal/connector/neverlog_test.go`): redirect the standard logger to a buffer and drive real request paths (token-issuer rehash-persist-failure with a distinctive client secret; a real search+get flow through the real `StdoutAuditLogger` with seeded PII; the connector's `/auth`/`/identity` across all outcomes with a distinctive vendor username/password/access-token) — the lint check's complement, catching what a static rule can miss. Verified each mechanism can actually fail (injected a real leak, confirmed catch, reverted).\n\n## Verification\n\n- `go build ./...`, `go vet ./...`, `go test ./...` — all clean.\n- `staticcheck ./...`, `gofmt -l` — clean.\n- `gitleaks detect` — clean (reworded initially-high-entropy test fixture values after a first pass flagged them as false-positive `generic-api-key` matches).\n- 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 correct names/values.\n\n## Who did the work\n\nRenata Cole (03, implementation) — Theo Bergman (04, metric-name/mechanism agreement) — Priya Nandakumar (05, alert-formula ruling) — Naomi Voss (01, PO, refinement).\n\nRefinement doc: `04-infra-devops/refinement/LT-49.md`.\n\n🤖 Generated with [Claude Code](https://claude.com/claude-code)\n\nhttps://claude.ai/code/session_011Cuba4JUvrsQCrTdUj4yzk\nEOF\n)\""

  "description": "Oren review of PR #59",
  "subagent_type": "oren-castellan",
  "prompt": "Review PR #59 on the loginid-takehome repo (branch feature/LT-49): https://github.com/wtvamp/loginid-takehome/pull/59\n\nContext: this is LT-49 (observability), 03's half only — metrics exposure at LT-44's sweep layer, and a never-log-list enforcement test at the application layer. Full acceptance criteria in 04-infra-devops/refinement/LT-49.md if useful. Key points:\n\n1. internal/sweep.PrometheusMetricEmitter (new, replaces LT-44's old StdoutMetricEmitter) uses real github.com/prometheus/client_golang Gauge/GaugeVec objects in a private prometheus.Registry. `Render(w io.Writer) error` gathers the registry and writes real Prometheus text exposition format via github.com/prometheus/common/expfmt. cmd/api-service's runSweepMode calls this once after all classes are attempted, writing to os.Stdout.\n2. New MetricEmitter interface method `MarkRunStarted(now time.Time)`, called unconditionally at the very top of `Run()` (internal/sweep/sweep.go), backing a new `sweep_last_run_timestamp_seconds` Gauge — deliberately NOT wired into any alert rule (confirmed with 04's lead in this session that Priya's alert-formula ruling made the originally-planned skip-vs-dead alerting role for this metric redundant; it's now just a supplementary kubectl-logs-level debugging signal).\n3. Two new test files: internal/api/neverlog_test.go and internal/connector/neverlog_test.go. Both redirect the standard library's package-level logger (`log.SetOutput`) to a buffer and drive REAL request paths with seeded, distinctive-but-low-entropy fixture strings (e.g. \"this fixture password must never appear in logs\" — deliberately reworded from higher-entropy leetspeak strings after gitleaks flagged the originals as false-positive generic-api-key matches), asserting the fixture strings never appear in captured log output. internal/api's test covers: the token issuer's opportunistic-rehash-persist-failure log line (with a real drifted-hash scenario forcing UpdateSecretHash to fail) and a real search+get flow through the actual StdoutAuditLogger with seeded PII (name/phone/street address). internal/connector's test covers: NewAuthHandler across success/vendor-rejection with a distinctive username+password, and NewIdentityHandler across success/vendor-rejection/no-token-sent with a distinctive vendor access token.\n\nI already live-verified the metrics-rendering path against a real throwaway Postgres (ran the actual api-service binary with APP_MODE=sweep, confirmed genuine parseable Prometheus text exposition output with correct values) and manually confirmed the never-log tests can actually fail (injected a real secret leak into tokenhandler.go's log line, watched the test catch it, reverted) — so please focus your review on:\n\n1. `PrometheusMetricEmitter`'s registry/Gauge construction (internal/sweep/sweep.go): any risk of a duplicate-registration panic, a race if this were ever called concurrently (it isn't today — one-shot batch process — but check whether the design assumes that safely or just gets lucky), or a metric family that could silently fail to register/gather.\n2. The never-log tests' actual coverage: do they really exercise a meaningfully different code path than the existing (non-never-log) tests for the same handlers, or are they redundant restatements? Is there a real, plausible future regression each test would actually catch that the existing test suite wouldn't?\n3. Whether capturing global log output via `log.SetOutput`/`log.Writer()` (shared package-level state) creates any risk of test flakiness or false negatives if Go's test runner ever parallelizes these tests with `t.Parallel()` (check whether any of these new tests, or nearby tests in the same packages, call t.Parallel()).\n4. Any other correctness issue in the diff.\n\nRead the actual diff (gh pr diff 59, or check out the branch) rather than trusting this description. Report back findings in under 300 words — concrete issues only, with file:line references."

One wrinkle worth flagging: I'd proposed a sweep_last_run_timestamp_seconds heartbeat metric for skip-vs-dead alerting, but Priya's alert-formula ruling landed mid-implementation and made that redundant — her RetentionSweepNotReporting rule gets the same distinction from per-class metric staleness alone. Reconciled with Theo: kept the metric as a supplementary kubectl-logs-only debugging signal, explicitly not wired into any alert rule, so nothing here conflicts with her design.\n\nOren reviewed — no blocking findings, one doc-comment addition taken (t.Parallel() incompatibility note on the log-capture helper). Also caught and fixed a gitleaks false-positive myself before pushing (reworded high-entropy test fixture strings to low-entropy plain-English ones).\n\nReady for whatever's next once Theo's alert-rule/sink PR lands alongside this.",

- **The `idp_cache_orphan` window drops below ~3 days.** `I` must shrink with it — at W = 2d and I = 24h the alert threshold would be 4 days, double the window.
- **`RetentionSweepSkipRate` fires.** That means run duration D is approaching I. Either shrink I or raise per-batch throughput; the skip-rate alert exists to surface this *before* the other two trip.
- **The `direct` class starts dominating run time.** Three sequential calls in one Job means a slow 24-month sweep delays the 7-day one. At take-home data volumes this is irrelevant; if it stops being irrelevant, split the schedules and accept a per-class `I` in the alert config.

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.\n\n**Fixed in `cmd/api-service/main.go`'s `runSweepMode`:**\n- 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.\n- 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.\n- 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`.\n- 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.\n\n**Coordination with Theo (04):** my `sweepDBConnectTimeout` (20s) is the inner bound; his CronJob's `activeDeadlineSeconds` (already `900` per PR #57/#62) is the outer bound and stays comfortably larger — nothing on his manifest needs to change for this fix to be correctly layered, but he should set `SWEEP_INTERVAL_SECONDS` to match his CronJob's actual schedule so the startup log line is accurate rather than \"unset\".\n\n**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.\n\n---\nWork-By: Naomi Voss (PO, live-run finding); Renata Cole (03, fail-loud fix); Theo Bergman (04, NetworkPolicy fix, activeDeadlineSeconds coordination)."

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."

This is 03's fix for the other half: the sweep code itself must fail loud on an unreachable database, not hang, regardless of network fixes elsewhere.\n\n**Root cause:** `dao.New`/`sql.Open` never dial, so nothing bounded the first *actual* connection attempt — it 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.\n\n**Fixed in `cmd/api-service/main.go`'s `runSweepMode`:**\n- A startup log line fires before anything touches the database — an operator sees the process reached the DB step immediately, not after minutes of silence.\n- A bounded connectivity check (`sweepDBConnectTimeout = 20s`, middle of the requested 10–30s range) via a dedicated `*sql.DB.PingContext`, before `sweep.Run` is ever called.\n- `classifySweepDBConnectError` names the failure class (`connect_timeout`/`connection_refused`/`dns_error`/`unknown`) in one structured log line on failure; the process then exits non-zero immediately, so a failed Job frees the `concurrencyPolicy: Forbid` slot for the next scheduled run.\n- New `SWEEP_INTERVAL_SECONDS` env var (purely descriptive) echoes the CronJob's own schedule in the startup log line.\n\n**Flagged to Theo (04), checked directly against the manifest:** `deploy/manifests.yaml`'s CronJob has `startingDeadlineSeconds` but no explicit `activeDeadlineSeconds` — my 20s inner bound has no stated outer bound to coordinate against yet.

  "description": "Oren review of PR #64",
  "subagent_type": "oren-castellan",
  "prompt": "Review PR #64 on the loginid-takehome repo (branch fix/sweep-db-connect-timeout): https://github.com/wtvamp/loginid-takehome/pull/64\n\nContext: Naomi (PO) found live that the LT-44 retention-sweep CronJob's pod sat \"Running\" for minutes with one TCP socket in SYN_SENT to Postgres (a NetworkPolicy gap on 04's side, being fixed separately) and never logged anything at all. This PR is 03's fix: the sweep code (cmd/api-service's APP_MODE=sweep mode) must fail loud on an unreachable database instead of hanging, independent of whatever network fix lands.\n\nRoot cause: `dao.New`/`sql.Open` never actually dial a connection — they just validate the driver/DSN string. So nothing bounded the FIRST real connection attempt, which happened inside `internal/sweep.Run`'s own first `DeleteExpired` call, using a context derived only from `signal.NotifyContext(context.Background(), syscall.SIGTERM, syscall.SIGINT)` — no deadline of its own. A genuinely unreachable database meant an unbounded hang.\n\nThe fix, in cmd/api-service/main.go's `runSweepMode`:\n1. A `log.Printf(\"api-service: sweep starting, classes=..., interval_seconds=%s\", interval)` line fires immediately, before anything touches the database.\n2. A NEW bounded connectivity check: opens a separate `*sql.DB` via `sql.Open(driverName, cfg.DBDSN)` (using the existing `sqlDriverNameFor` helper), then calls `pingDB.PingContext(pingCtx)` where `pingCtx` has a `context.WithTimeout(context.Background(), sweepDBConnectTimeout)` (20 seconds). On ping error, logs a classified failure line via a new `classifySweepDBConnectError(err) string` helper (checks `errors.Is(err, context.DeadlineExceeded)` for \"connect_timeout\", else substring-matches \"connection refused\" and \"no such host\" in the error text, else \"unknown\") and calls `os.Exit(1)` immediately — never proceeding to `sweep.Run` at all.\n3. Only if the ping succeeds does execution continue to open `repo` via `dao.New` and call `sweep.Run` as before.\n4. New `config.SweepIntervalSeconds` field (purely descriptive env var `SWEEP_INTERVAL_SECONDS`, classified in `config.OptionalEnvVars` — never read by internal/sweep's own logic, just echoed in the startup log line).\n\nI already live-verified this against a real unreachable database (a non-routable IP as the Postgres host) and confirmed: the startup line appears immediately, the process fails after exactly 20 seconds with `class=connect_timeout` logged, and exits non-zero. I also re-ran it against a real reachable Postgres to confirm the happy path has no regression.\n\nPlease focus your review on:\n1. Is there any ordering bug or resource-leak risk in the new ping-check block — e.g., could `pingDB` (the separate `*sql.DB` handle) leak a connection if `PingContext` times out vs. succeeds vs. errors immediately? Check that `pingDB.Close()` is called on every exit path.\n2. Does `os.Exit(1)` called from inside this ping-check block (nested inside an `if driverName := sqlDriverNameFor(...); driverName != \"\"` block, itself inside `runSweepMode`) correctly skip all the `defer` statements that were registered EARLIER in the function (there's a `defer func() { _ = repo.Close() }()` registered right after `dao.New` succeeds, before this ping check runs) — is that a problem? (Hint: `os.Exit` famously does NOT run deferred functions — is that acceptable here, given repo was already opened via `dao.New` by this point, or does this leak whatever `dao.New` set up? Check what dao.New/sql.Open actually allocate and whether skipping the deferred Close matters given the process is about to exit anyway.)\n3. Whether `classifySweepDBConnectError`'s substring-matching approach on `err.Error()` is fragile in a way that matters (e.g., could a legitimate, different error accidentally match \"connection refused\" or \"no such host\" and be misclassified, in a way that would mislead an operator)?\n4. Any other correctness issue.\n\nRead the actual diff (gh pr diff 64, or check out the branch) rather than trusting this description.

Live-verified against a real unreachable DB and a real reachable one — no regression.\n\nOne thing I found checking deploy/manifests.yaml directly for the activeDeadlineSeconds coordination PM asked for: the CronJob currently has startingDeadlineSeconds: 900 but no explicit activeDeadlineSeconds at all — your own PR #57 comment said this was deliberate (\"a stuck sweep should retry like any other Job,\" relying on the default backoffLimit: 6 rather than a stated wall-clock ceiling). My 20s inner connect-timeout doesn't strictly need an outer bound to be correct, but if you want one for defense-in-depth against some other stuck-pod scenario, worth adding now. Recorded as your own follow-up in refinement/LT-44.md, not blocking my PR. Let me know if you want it any different than what's there.\n\nAlso added a new SWEEP_INTERVAL_SECONDS env var (purely descriptive, optional) — set it in your CronJob manifest to match the real schedule if you want the sweep's own startup log line to say the real interval instead of \"unset\".",
