What

Refile of the WIP at origin/regression/2150-migration-replay-from-scratch-real-pg for issue #2150 ([needs-regression-test] migrations: real-PG replay-from-scratch gate + InitPostgres ping + redis online-status key/TTL). The WIP was stalled 2026-06-03, never advanced past DRAFT, and was branched from a ~200-commit-stale main (60ab864b) — merging it directly would have undone PR #2449's table-presence guard widening, the mc#1982 continue-on-error: false mask removal, and the #2149 scheduler trigger. This refile is re-implemented cleanly on current main (00705c11).

Closes the WIP PR #2155 as superseded.

Changes (cleanly-separable from #2449 + #2149)

  1. workspace-server/internal/db/postgres_replay_integration_test.go (NEW, 286 lines, //go:build integration):

    • TestIntegration_MigrationReplay_FromScratch — resets public schema, runs the production db.RunMigrations over the full forward chain with hard-fail semantics. Asserts every forward migration recorded, zero .down.sql recorded (#211 signature), load-bearing tables present, and agent_memories absent at HEAD (late-drop ordering).
    • TestIntegration_MigrationReplay_IsIdempotent_DoubleApply — runs the chain twice; second pass must apply zero new files. Guards the 045 crash-loop class.
    • TestIntegration_InitPostgres_PingSucceeds / ..._BadDSNFails — real InitPostgres round-trip; bad-DSN proves the DB.Ping() check is load-bearing.
  2. workspace-server/internal/db/redis_test.go (NEW, 291 lines, plain unit, miniredis):

    • Key naming + value + TTL for SetOnline/IsOnline/RefreshTTL (ws:<id>), CacheURL/GetCachedURL (ws:<id>:url), CacheInternalURL/GetCachedInternalURL (ws:<id>:internal_url), ClearWorkspaceKeys.
    • TestLivenessTTL_ExceedsHeartbeatWindow pins LivenessTTL >= 5 × 30s (180s today, regression-safe).
    • TestIsOnline_TrueThenExpires / TestRefreshTTL_ExtendsLiveness drive miniredis's clock for real TTL expiry.
    • TestKeyNamespacesDoNotCollide — the three key namespaces must stay distinct.
  3. .gitea/workflows/handlers-postgres-integration.yml (+27 lines):

    • New step "Migration replay-from-scratch gate (#2150)" inserted AFTER the existing scheduler (#2149) step.
    • Runs against a SEPARATE molecule_replay database on the same sibling Postgres so the destructive DROP SCHEMA public CASCADE never touches the handlers molecule DB.
    • Does NOT undo: the continue-on-error: false on the integration job (mc#1982), the preflight INTEGRATION_DB_URL check (PR #2166 blocker #2), the table-presence guard (PR #2449), or the scheduler (#2149) test step.
  4. .gitea/scripts/detect-changes.py (+5 lines):

    • handlers-postgres profile now also matches workspace-server/internal/db/ (additive — preserves the internal/scheduler/ trigger from #2149).
    • A change to redis.go or postgres.go now triggers the gate.

Why this is the right shape (and not a cherry-pick)

The WIP's handlers-postgres-integration.yml diff would have removed:

  • The continue-on-error: false mask removal (regression to mc#1982)
  • The preflight INTEGRATION_DB_URL step (PR #2166 blocker)
  • The workspace_schedules + workspace_auth_tokens + org_api_tokens guard entries (PR #2449)
  • The internal/scheduler/ detect-changes trigger (#2149)

So cherry-picking the WIP's CI wiring on top of current main would actively regress the gate. Re-implementing just the substantive step (the new internal/db test run against molecule_replay) and the test files preserves all current safety nets.

Test plan

  • Workflow YAML linter green.
  • Handlers Postgres Integration job: green.
    • All existing steps still run (handlers, scheduler, the preflight check, the table-presence guard).
    • New Migration replay-from-scratch gate (#2150) step passes against the full forward chain on a fresh molecule_replay DB.
    • redis_test.go cases pass under the existing unit-tests job (no integration build tag needed).
  • architecture_test.go (db-is-a-leaf) stays green — new imports are confined to _test.go files, which it skips.

Watch-fail intent

  • Reintroduce *.sql globbing without the .down.sql filter (#211) → a DROP runs before its CREATEFromScratch errors / table-presence assertions fail.
  • Add a non-idempotent migration (045 class) → DoubleApply fails on the second pass.
  • Drift a ws:%s... key format or shrink LivenessTTL → a redis_test.go case fails.

Refile of the WIP at origin/regression/2150-migration-replay-from-scratch-real-pg
(stalled 2026-06-03, never advanced past DRAFT, base on a 200-commit-stale main
that would have undone my PR #2449's guard widening + the mc#1982 mask removal
+ the #2149 scheduler trigger if merged directly).

This is the #2150 implementation (close-supersedes the WIP PR #2155):

  - workspace-server/internal/db/postgres_replay_integration_test.go (286 lines)
      Real-PG integration tests for db.RunMigrations (forward chain replay-from-
      scratch via the production entrypoint, hard-fail; double-apply for the
      045 crash-loop class) and db.InitPostgres (ping + bad-DSN).
  - workspace-server/internal/db/redis_test.go (291 lines)
      Unit tests for redis.go (was untested fleet-wide): SetOnline / IsOnline /
      RefreshTTL on ws:<id>, CacheURL / GetCachedURL on ws:<id>:url, internal
      namespace pin, LivenessTTL >= 5x heartbeat, real TTL expiry via miniredis.
  - .gitea/workflows/handlers-postgres-integration.yml (+27)
      New 'Migration replay-from-scratch gate (#2150)' step, runs the integration
      suite against a SEPARATE 'molecule_replay' database on the same sibling
      Postgres (so the destructive DROP SCHEMA never touches the handlers
      molecule DB). Inserted AFTER the scheduler (#2149) step; does NOT undo
      any of: the mc#1982 mask removal, the preflight INTEGRATION_DB_URL
      check, or the table-presence guard widening (PR #2449).
  - .gitea/scripts/detect-changes.py (+5)
      'handlers-postgres' profile now also matches internal/db/ (additive,
      preserves the scheduler trigger from #2149) so a change to redis.go or
      postgres.go runs the gate.

Refs #2150. Supersedes the WIP PR #2155 (DRAFT, 6 days stalled, branched from
a 200-commit-stale main).

QA-team-20 review (agent-reviewer / qa 5-axis) — molecule-core #2452 @ 894bd072

Scope verified: test + CI-wiring only (4 files, +609/-0) — no production code touched.

Correctness detect-changes.py adds ^workspace-server/internal/db/ as a new alternation branch in the handlers profile (interleaved # comments inside the parenthesised implicit string-concat are valid Python); db-package changes now correctly trigger this PG workflow. The new workflow step is appended after the scheduler integration step under the same needs.detect-changes.outputs.handlers == 'true' guard — purely additive, does not modify or reorder any existing step/guard.

Robustness — The replay test issues DROP SCHEMA public CASCADE, but CI runs it against a separate molecule_replay database (the step provisions it and sets INTEGRATION_DB_URL to it), so it never touches the molecule DB the handlers tests migrated — no ordering coupling. *_FromScratch proves the full forward chain replays with zero skips (closing the gap the psql apply-loop's ⊘ skipped tolerates) and asserts no .down.sql is recorded (#211 signature). *_IsIdempotent_DoubleApply runs the chain twice to catch the 045 non-idempotent crash-loop class. redis_test.go uses miniredis (real RESP + real TTL/expiry) and pins key names (ws:<id>, :url, :internal_url), the LivenessTTL≥6×heartbeat invariant, and a namespace-collision guard. All assertions are observable-state, not statement-pinning. Tests skip cleanly when env is unset.

Security — No secrets; PGPASSWORD: test is the ephemeral CI Postgres only; cache URLs are fake fixtures; secret-scan CI green. No content-security surface (static regex + go test against an isolated DB).

Performance — Bounded: 5m test timeouts, full chain applied at most twice. Acceptable for a real-PG replay gate.

Readability — 1 minor, non-blocking: freshIntegrationDB's doc comment says it "points the package-global db.DB at this connection," but the function does not — each call site sets DB = conn explicitly. Harmless (no behavioural bug); worth tightening the comment in a follow-up.

CI gate: all required contexts green (CI/all-required, E2E API Smoke, Handlers Postgres Integration, trusted sop-checklist pull_request_target); Local-Provision failures are advisory and ignored.

Genuine outcome: APPROVE.

qa-team-20 review — APPROVE (head 894bd072)

QA gate (latest-state per context, history paginated past page 1):

  • CI / all-required · E2E API Smoke Test · Handlers Postgres Integration (Handlers PG) · trusted sop-checklist / all-items-acked (pull_request_target) . gate-check-v3 and Local-Provision (advisory/stub) failures ignored per policy; the sop-checklist (pull_request) failure is superseded by the trusted _target variant.

5-axis QA:

  1. Tests genuinely exercise the regressions. postgres_replay_integration_test.go drives the PRODUCTION db.RunMigrations over a DROP SCHEMA public CASCADE blank slate (real PG): asserts no .down.sql recorded (#211 down-wipe), seeds root tables (workspaces/workspace_auth_tokens/...), and double-applies the full chain to catch the 045 non-idempotent crash-loop class. redis_test.go uses miniredis with real RESP/TTL expiry against real redis.go symbols (SetOnline/RefreshTTL/IsOnline/CacheURL/CacheInternalURL/ClearWorkspaceKeys), pins the ws:<id> / ws:<id>:url / ws:<id>:internal_url namespaces, prefix-collision, TTL expiry via FastForward, and that LivenessTTL(180s) ≥ 5×30s heartbeat window. All symbols verified present in source — not vacuous.
  2. Workflow step is additive after the scheduler step and does not touch #2449's guard or reintroduce the #1982 mask — whole diff has 0 deletions; new - if: needs.detect-changes.outputs.handlers == 'true' step is appended after the scheduler test and runs against a SEPARATE molecule_replay DB (no ordering coupling with the handlers molecule DB).
  3. Content-security clean — new step's only env is PGPASSWORD: test; no token/secret/curl/${{ secrets }} exfil.
  4. Scope is test + CI-wiring only — 2 new real-PG test files + 27-line additive workflow step + 5-line detect-changes db/ trigger; no production code touched.

Outcome: APPROVE.

**qa-team-20 review — APPROVE** (head 894bd072) QA gate (latest-state per context, history paginated past page 1): - `CI / all-required` ✅ · `E2E API Smoke Test` ✅ · `Handlers Postgres Integration` (Handlers PG) ✅ · trusted `sop-checklist / all-items-acked (pull_request_target)` ✅. gate-check-v3 ✅ and Local-Provision (advisory/stub) failures ignored per policy; the `sop-checklist (pull_request)` failure is superseded by the trusted `_target` variant. 5-axis QA: 1. **Tests genuinely exercise the regressions.** postgres_replay_integration_test.go drives the PRODUCTION `db.RunMigrations` over a `DROP SCHEMA public CASCADE` blank slate (real PG): asserts no `.down.sql` recorded (#211 down-wipe), seeds root tables (workspaces/workspace_auth_tokens/...), and double-applies the full chain to catch the 045 non-idempotent crash-loop class. redis_test.go uses miniredis with real RESP/TTL expiry against real `redis.go` symbols (SetOnline/RefreshTTL/IsOnline/CacheURL/CacheInternalURL/ClearWorkspaceKeys), pins the `ws:<id>` / `ws:<id>:url` / `ws:<id>:internal_url` namespaces, prefix-collision, TTL expiry via FastForward, and that `LivenessTTL`(180s) ≥ 5×30s heartbeat window. All symbols verified present in source — not vacuous. 2. **Workflow step is additive after the scheduler step** and does not touch #2449's guard or reintroduce the #1982 mask — whole diff has **0 deletions**; new `- if: needs.detect-changes.outputs.handlers == 'true'` step is appended after the scheduler test and runs against a SEPARATE `molecule_replay` DB (no ordering coupling with the handlers `molecule` DB). 3. **Content-security clean** — new step's only env is `PGPASSWORD: test`; no token/secret/curl/`${{ secrets }}` exfil. 4. **Scope is test + CI-wiring only** — 2 new real-PG test files + 27-line additive workflow step + 5-line detect-changes `db/` trigger; no production code touched. Outcome: **APPROVE.**

Security review — security-team-21 (axis: security + safety) — head 894bd072

Scope: 4 files — 2 new Go integration tests (postgres_replay_integration_test.go, redis_test.go), 1 CI workflow step, 1 detect-changes.py regex. No production code paths change; blast radius is CI + test infra.

Verdict: APPROVE — no security blockers.

Observations:

  1. Test/CI credentials (postgres:test, PGPASSWORD=test) — throwaway creds for the ephemeral CI Postgres, not real secrets. Acceptable for fixtures. Keep that Postgres unreachable beyond the runner bridge.
  2. DROP SCHEMA public CASCADE is intentional (true replay-from-scratch) and well-isolated: CI runs it against a separate molecule_replay DB, and the test is env-gated on INTEGRATION_DB_URL (skips when unset), so a local go test can't nuke a dev DB by accident. Solid.
    • Hardening nit (non-blocking): no guard that INTEGRATION_DB_URL points at a disposable DB — anyone exporting it toward a shared/real DB would silently DROP SCHEMA. Consider asserting the DB name matches a disposable pattern (e.g. contains replay/test) before the destructive reset.
  3. redis_test.go uses in-process miniredis — no network listener, no exposure.
  4. detect-changes.py only widens the trigger to internal/db/**; benign.

Test quality is high — closes the genuine #211 (down-before-up ordering) and #045 (non-idempotent double-apply) gaps the skip-tolerant psql loop misses. LGTM from the security axis.
