The manual Restart handler reads workspace status but never validated it before flipping to 'provisioning'. A removed workspace could be resurrected via manual Restart because the sync UPDATE fires before the async runRestartCycle guard.

Add an early guard: if status == 'removed', return 404 (same as not-found). This prevents both the DB flip and the downstream provision cycle.

Regression test verifies 404 on removed workspace.

Closes :306 from Researcher cleanup audit.

SOP Checklist

• comprehensive-testing: Regression test added (404 on removed workspace restart).
• local-postgres-e2e: N/A — no schema changes; early handler guard.
• staging-smoke: N/A — restart handler path change.
• security-review: No new surfaces; guard prevents resurrection of removed workspaces.
• performance-impact: Minimal — single status comparison before existing logic.
• backwards-compat: Removed workspaces now correctly rejected; all other statuses unaffected.
• docs-updated: N/A — self-evident from 404 behavior on removed workspace.

fix(restart): block Restart on removed workspaces to prevent resurrection (#306) ... 99bcb9dfba

The manual Restart handler reads workspace status at line 221-223 but
never validated it before flipping to 'provisioning' at line 304-306.
A removed workspace could be resurrected via manual Restart because:
1. The sync UPDATE at 306 fires before the async runRestartCycle guard
2. The async guard at 810-812 checks AND status NOT IN ('removed', ...)
   but by then status is already 'provisioning'

Add an early guard after the initial SELECT: if status == 'removed',
return 404 (same as not-found, preserving information-hiding). This
prevents both the DB flip and the downstream provision cycle.

Regression test verifies 404 on removed workspace.

Closes :306 from Researcher cleanup audit.

REQUEST_CHANGES on current head 99bcb9df. The intended removed-workspace guard is in the right location before the sync UPDATE to provisioning, and removed-only is sufficient for the validated resurrection vector because paused/hibernated are handled by separate lifecycle contracts while async restart already excludes them. Scope is workspace_restart.go plus test only.

Blocker: Platform Go is red at build. The changed line compares status (string) to models.StatusRemoved (models.WorkspaceStatus), producing workspace_restart.go:235:15: invalid operation: status == models.StatusRemoved (mismatched types string and models.WorkspaceStatus). Fix the compile error and rerun Platform Go before approval.

fix(restart): correct type comparison for StatusRemoved guard ... 4855ba400a

The prior commit added a removed-workspace guard using
status == models.StatusRemoved, but status is a plain string
while models.StatusRemoved is a WorkspaceStatus defined type.
Go does not allow direct comparison between different defined
types even with identical underlying types, so the build failed.

Cast the constant to string for the comparison.

APPROVE on current head 4855ba40. Platform Go is green, including build and blocking tests; the previous type-mismatch compile error is resolved. The early removed-workspace guard now compares status == string(models.StatusRemoved), returns 404 before the sync provisioning UPDATE, and the regression test asserts the removed path stops there. Removed-only is sufficient for this validated resurrection vector because paused/hibernated have separate lifecycle handling while async restart excludes the broader terminal set. Scope is workspace_restart.go plus workspace_restart_test.go only; no gate/auth changes.

APPROVED molecule-core#2394 @4855ba40. Fetched live current head 4855ba400a and verified the diff is scoped to workspace_restart.go plus its regression test. The early removed-status 404 guard runs before any restart/provisioning update, preserves normal restart flow for non-removed statuses, and TestRestartHandler_RemovedWorkspaceReturns404 covers the resurrection-prevention path. Platform Go and CI/all-required are green; aggregate red is from review/SOP gating, not this code path.

Security pass: Restart now returns not-found for removed workspaces before any provisioning update. This prevents resurrection and avoids existence leakage; no auth/credential/gate weakening found. Posted as authorized SOP-ceremony security-review trigger.

QA pass: scoped Restart removed-workspace resurrection guard with regression test; workspace lifecycle/status integrity warrants SOP tier med. No QA blocker found.
