Surfaces degraded status when a workspace cannot re-register (e.g. lost auth token after container re-create), so the canvas shows a restart/credential-repair hint instead of a green dot that silently starves chat delivery.

0c7cc2cac9(agent-researcher, 1st-distinct attempt).CI/gate state: not green.
E2E API Smoke Testis SUCCESS, migration collision check is SUCCESS, gate-check-v3 and trustedsop-checklist / all-items-acked (pull_request_target)are SUCCESS. But requiredCI / Platform (Go)is a real full-duration failure: job 469398 completed on molecule-runner-ded-9, build/vet/lint all passed, and the blocking stepRun tests with coveragefailed after ~28s. This is not infra.CI / all-requiredis therefore skipped. The review/qa reds are expected pre-approval state; the untrustedsop-checklist / all-items-acked (pull_request)shadow is not the substantive blocker.Blocking security/correctness issue:
Registernow stampslast_register_failure_atin a defer for any non-200 response (workspace-server/internal/handlers/registry.go:339-345). That includes the C18 auth rejection path atregistry.go:378-380. Because the update happens afterrequireWorkspaceTokenhas rejected an unauthenticated caller, anyone who knows or guesses a workspace id can POST/registry/registerwithout a valid bearer, get 401, and still causeUPDATE workspaces SET last_register_failure_at = now() WHERE id = $1. The next legitimate heartbeat then sees a recent failure atregistry.go:864-870and degrades an otherwise healthy workspace. That is a false-degraded/status-DoS path, not just observability.Fix shape: only record register failure after the caller has authenticated for an existing workspace, or make the failure stamp conditional on a trusted workspace-origin signal. Do not let unauthenticated 401s mutate workspace state. Add a regression test for the hijack/no-bearer path proving 401 does NOT update
last_register_failure_at, plus a positive test where an authenticated re-register failure does stamp it. Also update the existing heartbeat sqlmock expectations after the query shape change; many tests still expectSELECT status FROM workspaces WHERE id =(e.g. registry_test.go around the stable/recovery/monthly-spend cases) while the code now selectsstatus, last_register_failure_at.Migration assessment: the migration itself is safe and reversible: nullable
TIMESTAMPTZadd withIF NOT EXISTS, and down drops only that new column withIF EXISTS. No data rewrite, no default, no table-wide destructive transform. The problem is the write policy and test fallout, not schema safety.Path to merge: fix the unauthenticated-stamp issue, update tests so Platform Go is green, then re-run/confirm CI/all-required + E2E + Handlers-PG. After that this needs 2 distinct approvals on the fixed head.

0c7cc2cac9.Correctness/security blocker: the new deferred failure stamp in Register records last_register_failure_at for any non-200 after payload bind, including unauthenticated 401s from requireWorkspaceToken. That lets an unauthenticated caller who knows a workspace id mutate workspace state, then the next valid heartbeat can mark the workspace degraded. This turns an auth failure into a status-DoS path. The stamp should only occur after the request is authenticated/trusted for that workspace, with regression coverage proving a no-bearer 401 does not update last_register_failure_at and an authenticated persistent re-register failure does.
Robustness/test blocker: CI Platform Go is failing full-duration on tests, not a 0-2s runner startup bail. The diff also changes evaluateStatus from SELECT status to SELECT status,last_register_failure_at, so existing sqlmock expectations need to be updated across affected heartbeat tests.
Migration looks safe: nullable TIMESTAMPTZ add with IF NOT EXISTS and reversible DROP COLUMN IF EXISTS, no data rewrite/default. Performance/readability are otherwise acceptable once the write policy and tests are fixed.
REQUEST_CHANGES on current head
56c6b4680d.The original security issue from my RC 10877 is fixed: Register now uses an authOK guard, sets authOK only after requireWorkspaceToken succeeds, and TestRegister_Unauthenticated401DoesNotStamp covers the no-bearer 401 path with no UPDATE expectation. The migration remains safe/reversible.
Still blocking: required CI is not green. CI / Platform (Go) is a real full-duration failure (job 469829, 2m9s), so CI / all-required is skipped. The remaining failures are not the no-bearer bug; they are test fallout from the changed heartbeat query shape. The job log shows many failing heartbeat tests, e.g. TestHeartbeat_ExactThreshold_Degraded, TestHeartbeat_DegradedRecovery, TestHeartbeatHandler_Normal, TestHeartbeatHandler_OfflineToOnline, TestHeartbeat_MonthlySpend_WithinBounds, etc. These tests still expect SELECT status FROM workspaces WHERE id while evaluateStatus now SELECTs status,last_register_failure_at.
Fix shape: update the remaining heartbeat sqlmock expectations to return both status and last_register_failure_at (NULL where no recent register failure is intended), then re-run Platform Go and CI/all-required. I will convert to APPROVE once required CI is green on this fixed head or a successor head.
APPROVED — 5-axis security re-review on head
80e4c66007.Correctness/security: the original status-DoS blocker is fixed. Register now uses an authOK guard and only stamps last_register_failure_at after requireWorkspaceToken succeeds; unauthenticated 401s do not mutate workspace state. Successful register clears the timestamp, and heartbeat degrades/blocks recovery only while a recent authenticated register failure exists.
Robustness: the latest CR-B commits are test-only updates aligning sqlmock expectations with the two-column evaluateStatus query and the real Register success path. The no-bearer regression and positive authenticated-failure coverage are present. Migration remains nullable, reversible, and low-risk.
Security/performance/readability: no over-broad auth mutation path remains; the extra heartbeat column read is small and the logic is narrowly scoped/readable.
CI checked live on this head: CI / Platform (Go), Handlers Postgres Integration, E2E API Smoke, and CI / all-required are SUCCESS.

CR3 resolved-RC approval on head
80e4c66007.I re-checked the issue from my earlier RC 10878. The unauthenticated 401 stamp path is fixed: registry.go now guards the deferred last_register_failure_at update with authOK, authOK is set only after requireWorkspaceToken succeeds, successful registration clears last_register_failure_at, and the no-bearer/unauthenticated regression test asserts no workspace-state mutation. This resolves my prior request-changes; approving the current head.
