What

CR-A diagnosed a cp-wide Platform-Go flake on the bootstrap-failed test path. Root cause: BootstrapFailed (workspace_bootstrap.go:104) calls captureRescueBundle which dispatches the rescue capture via rescueDispatch = func(fn func()) { go fn() } (rescue_wiring.go:129). The dispatched goroutine reads db.DB (via rescuestore.NewPostgres(db.DB).Persist(ctx, b)), and the test's setupTestDB t.Cleanup swaps db.DB back to prevDB — but the existing drainTestAsync only tracks handler-internal goAsync goroutines (via newHandlerHook + liveTestHandlers), NOT the rescueDispatch goroutines. So the rescue goroutine outlives the test and races the db.DB write — the 0x...d548 data race on platform/internal/db.DB documented at handlers_test.go:32.

Fix (test-only, no production touch)

Add rescueTestHarness(t, instanceID) to the two affected tests (TestBootstrapFailed_HappyPath and TestBootstrapFailed_TruncatesOversizedLogTail) — both reach the rescue-dispatch path (affected==1 → call captureRescueBundle).

The existing rescueTestHarness helper (rescue_wiring_test.go:25) makes rescueDispatch synchronous AND stubs rescue.RunRemote + rescue.Redact so no real EIC/SSH fires; the test asserts the HTTP response + sqlmock expectations, not the rescue side effect.

Tests that DO NOT need the harness (verified by tracing the handler)

• TestBootstrapFailed_AlreadyTransitioned: returns at workspace_bootstrap.go:87 (affected==0, no_change) BEFORE captureRescueBundle at line 104.
• TestBootstrapFailed_EmptyIDIs400: returns at line 39 (empty id) BEFORE the DB call.
• TestConsole_ReturnsNotImplementedWhenNoCP: Console() doesn't call captureRescueBundle.

Branch hygiene (lesson from cp#709 bundling RC)

Branched off clean origin/main (NOT off another feature branch). Branch: fix/core-2490-bootstrapfailed-rescue-race @ 717d1c06. File diff: workspace-server/internal/handlers/workspace_bootstrap_test.go only (+18/-0).

Verifier path

go test -race -count=50 ./workspace-server/internal/handlers/ -run BootstrapFailed

should pass cleanly post-merge. (No local go toolchain in this container; CI is source of truth.)

Sibling fix

fix/cp-709-bootstrapwatcher-test-race (PR #709 in molecule-controlplane) fixed a related but distinct race in the provisioner-pkg BootstrapWatcher (package-level timing-var mutation). This PR is the handlers-pkg counterpart — different file, different race, same theme (orphan test-goroutine racing package-level state in t.Cleanup).

fix(test): TestBootstrapFailed rescue-dispatch orphan-goroutine race (#2490) ... 717d1c06c8

CR-A diagnosed a cp-wide Platform-Go flake on the bootstrap-failed
test path. Root cause: `BootstrapFailed` (workspace_bootstrap.go:104)
calls `captureRescueBundle` which dispatches the rescue capture via
`rescueDispatch = func(fn func()) { go fn() }` (rescue_wiring.go:129).
The dispatched goroutine reads `db.DB` (via
`rescuestore.NewPostgres(db.DB).Persist(ctx, b)`), and the test's
`setupTestDB` t.Cleanup swaps `db.DB` back to prevDB — but the
existing `drainTestAsync` only tracks handler-internal `goAsync`
goroutines (via `newHandlerHook` + `liveTestHandlers`), NOT the
`rescueDispatch` goroutines. So the rescue goroutine outlives the
test and races the `db.DB` write — the 0x...d548 data race on
platform/internal/db.DB documented at handlers_test.go:32.

Fix (test-only, no production touch):
Add `rescueTestHarness(t, instanceID)` to the two affected tests
(`TestBootstrapFailed_HappyPath` and
`TestBootstrapFailed_TruncatesOversizedLogTail`) — both reach the
rescue-dispatch path (affected==1 → call `captureRescueBundle`).
The existing `rescueTestHarness` helper (rescue_wiring_test.go:25)
makes `rescueDispatch` synchronous AND stubs `rescue.RunRemote` +
`rescue.Redact` so no real EIC/SSH fires; the test asserts the HTTP
response + sqlmock expectations, not the rescue side effect.

Tests that DO NOT need the harness (verified by tracing the handler):
- `TestBootstrapFailed_AlreadyTransitioned`: returns at
  workspace_bootstrap.go:87 (affected==0, no_change) BEFORE
  captureRescueBundle at line 104.
- `TestBootstrapFailed_EmptyIDIs400`: returns at line 39 (empty id)
  BEFORE the DB call.
- `TestConsole_ReturnsNotImplementedWhenNoCP`: Console() doesn't
  call captureRescueBundle.

Branched off clean `origin/main` (lesson from the cp#709 bundling
RC: never branch off another feature branch). Branch:
`fix/core-2490-bootstrapfailed-rescue-race`. File diff:
`workspace-server/internal/handlers/workspace_bootstrap_test.go`
only (test-only, +16/-0).

Verifier path:
`go test -race -count=50 ./workspace-server/internal/handlers/ -run BootstrapFailed`
should pass cleanly post-merge. (No local go toolchain in this
container; CI is source of truth.)

Security 5-axis — APPROVE. Test-only race-guard (TestBootstrapFailed rescue-dispatch orphan).

Diff = ONLY workspace_bootstrap_test.go: adds rescueTestHarness(t, …) to TestBootstrapFailed_HappyPath + _TruncatesOversizedLogTail. It makes the rescue-dispatch (rescueDispatch = go fn()) synchronous in-test and stubs remote/redact, so the rescue goroutine no longer outlives the test and races setupTestDB's t.Cleanup db.DB swap — closes the #2490 db.DB race (the 0x…d548 diagnosis) for these two tests.

• Test-only: no production code, no secret/auth/injection surface; stubs ensure no real EIC/SSH fires from the test.
• Non-vacuous: tests still assert the HTTP response + sqlmock expectations (the harness only synchronizes the side-effect dispatch, doesn't weaken the assertions).
• Required gates GREEN (CI/all-required, E2E API Smoke, Handlers-PG, trusted sop-checklist). Shellcheck (E2E scripts) is pending but non-required + path-irrelevant (no shell files changed).

No security issues. APPROVE → 2-distinct with CR-B qa → merge.

qa 2nd-lane (5-axis, full diff read) — APPROVE. Correctly closes the exact data race I root-caused in the #2490 Platform-Go CI-log diagnosis.

• CORRECTNESS: the race was TestBootstrapFailed's rescue path: BootstrapFailed -> captureRescueBundle dispatches rescueDispatch = go fn() (async); that rescue goroutine reads db.DB and OUTLIVES the test, while setupTestDB's t.Cleanup swaps db.DB back to prevDB -> concurrent read/write -> -race flags it (my diagnosis: setupTestDB cleanup vs the async rescue goroutine reading a package global). FIX: wrap the two affected tests (the affected==1 -> captureRescueBundle path: "i-crashed" + "i-spammy") in rescueTestHarness, which makes rescueDispatch SYNCHRONOUS so the goroutine completes WITHIN the test body (before t.Cleanup) -> no race; and stubs the remote/redact so no real EIC/SSH fires. This is the correct fix shape: it's a TEST-harness fix (production rescueDispatch stays async go fn()), because the race was a test-only artifact (the t.Cleanup db.DB swap racing the test-spawned goroutine; production has no such cleanup). Both affected tests guarded.
• ROBUSTNESS: race-free under -race (the goal); covers both rescue-dispatch tests. SECURITY: test-only, harness stubs remote -> no side-effects, content-clean. PERF: synchronous test dispatch, deterministic. READABILITY: comments precisely tie to the #2490 race + mechanism. Author agent-dev-b != me.
  2-distinct now (agent-researcher 10609 + agent-reviewer). REQUIRED gates GREEN (advisory-red excluded). Proceeding to merge-probe — closes the CI-stability race the #2490 diagnosis surfaced. +1.
