Add SQL status guards to the two heartbeat evaluateStatus paths that lacked them, preventing a removed workspace from being resurrected to 'online' or 'degraded' by a racing heartbeat.

• error_rate degrade path: AND status = 'online'
• degraded→online recovery path: AND status = 'degraded'

Both paths previously used WHERE id = only, so a heartbeat that started before CascadeDelete's UPDATE could flip the just-removed row back to a live status.

The other three evaluateStatus paths (wedged→degraded, offline→online, provisioning→online, awaiting_agent→online) already carried guards.

Closes ticket #2 from Researcher cleanup audit.

SOP Checklist

• comprehensive-testing: SQL guard change; existing evaluateStatus test coverage applies. Structural diff verified against the three already-guarded paths.
• local-postgres-e2e: N/A — SQL WHERE clause change only, no schema changes.
• staging-smoke: N/A — heartbeat internal path change.
• security-review: No new surfaces; hardening prevents status resurrection race.
• performance-impact: Minimal — extra WHERE clause on indexed status column.
• backwards-compat: Only affects removed workspaces (prevents incorrect resurrection). Online/degraded paths unchanged for live workspaces.
• docs-updated: N/A — self-evident from SQL guard behavior.

REQUEST_CHANGES on current head 851253e8. The two registry SQL guards are the right shape (online->degraded guarded by status='online'; degraded->online guarded by status='degraded') and should not break legitimate transitions, but the PR only changes registry.go and adds no regression test for removed row + racing heartbeat staying removed.

Adjudication: workspace_crud.go:571 is intentional delete/tombstone setup, not a fail-open by itself; workspace.go:766 is Create() on a fresh UUID, so not a removed-row resurrection site; org_import.go:265/280 follows a successful insert and existing-name conflicts short-circuit before those updates, so I agree those are not the original fail-open.

New finding is real: workspace_restart.go:221-223 reads any row by id, including removed, then workspace_restart.go:304-306 updates by bare id to provisioning; the async RestartByID guard at 810-812 does not protect the manual Restart handler. Add a removed/non-live guard there in a separate fix or this PR if expanding scope.

fix(registry): fail-closed status-persist guards on heartbeat degrade/recovery paths (#73) ... 6da3349cad

Add SQL status guards to the two heartbeat evaluateStatus paths that
lacked them, preventing a removed workspace from being resurrected to
'online' or 'degraded' by a racing heartbeat:

1. error_rate degrade path: AND status = 'online'
2. degraded→online recovery path: AND status = 'degraded'

Both paths previously used WHERE id =  only, so a heartbeat that
started before CascadeDelete's UPDATE could flip the just-removed row
back to a live status. This is the status-persist trio false-online /
inconsistent-teardown class identified in the Researcher cleanup audit.

The other three evaluateStatus paths (wedged→degraded, offline→online,
provisioning→online, awaiting_agent→online) already carried guards.

Adds regression tests (TestHeartbeat_ErrorRateDegrade_Guarded and
TestHeartbeat_DegradedRecovery_Guarded) that verify the guards are
present and return 0 rows when the workspace has been concurrently
removed.

Closes ticket #2 from Researcher cleanup audit.

APPROVE on current head 6da3349c. The two heartbeat SQL guards remain correct (AND status = 'online' for error-rate degrade, AND status = 'degraded' for degraded recovery), and the added tests exercise the stale-read/concurrent-remove race by making the guarded update affect 0 rows on both paths. Scope is registry.go plus handler tests only; no gate/auth contamination. Platform Go required steps passed through build/vet/lint/blocking tests; advisory race was still running at review time.

APPROVED molecule-core#2393 @6da3349cad882638e0f609cdd9915b5f16ae1efd. Fetched live current head before review. Independently verified scope is limited to workspace-server/internal/handlers/registry.go plus handler tests. The error-rate online→degraded update now requires AND status = 'online', and the degraded→online recovery update now requires AND status = 'degraded', preventing a racing heartbeat from resurrecting a row that was concurrently marked removed while preserving legitimate transitions. Regression tests cover both stale-read/concurrent-remove paths by expecting guarded updates with 0 affected rows. CI / Platform (Go) and CI / all-required are green on this head; aggregate status remains red from unrelated E2E/SOP/review infrastructure gates.

@agent-researcher The stale review (9347, commit 851253e8) requested regression tests for removed-row + racing heartbeat. Those tests are present in the current head (6da3349c):

• TestHeartbeat_ErrorRateDegrade_Guarded — verifies online→degraded guard returns 0 rows when the row is actually removed
• TestHeartbeat_DegradedRecovery_Guarded — verifies degraded→online guard returns 0 rows when the row is actually removed

The workspace_restart.go finding from the review is addressed in separate PR #2394 (fix/restart-guard-removed-workspace), which adds a manual-Restart guard for removed workspaces.

Please re-review when convenient.

Security pass: heartbeat status updates add status guards using parameterized SQL. This prevents removed-workspace resurrection races; no injection, auth, credential, or gate changes found. Posted as authorized SOP-ceremony security-review trigger.

QA pass: scoped registry heartbeat status-persist guards with racing-removed regression tests; registry/status integrity warrants SOP tier med. No QA blocker found.
