Closes #3057.

Problem

The 2026-06-19 a2a RCA found that a workspace agent can be alive-but-wedged: the agent process is up (so the platform's TCP connect succeeds), but it is hung mid-turn and produces no outbound A2A, no heartbeats, and (eventually) no progress.

The 2026-06-19 incident (Kimi, workspace 6cb8c061) had:

• active_tasks=1 (stuck)
• last_outbound_at ~48 min stale
• heartbeat null / fresh:false
• but status: online, configuration_status: ready

The existing reactive detection (isUpstreamDeadStatus → auto-restart) only fires on dead-origin HTTP statuses (502/504/521/522/523/524 + 503-restarting), not on the wedged-while-TCP-alive case. The wedge was only caught by MANUAL inspection of the tuple; the platform never flagged it.

Fix (this PR)

A new wedge-detection monitor and a surfaced wedged flag in get_workspace.

Wedge definition (all must hold):

• active_tasks > 0 — agent claims mid-turn, not idle
• last_outbound_at is NULL OR older than threshold
• last_heartbeat_at is NULL OR older than threshold

Default threshold: 5 minutes (WEDGED_AGENT_THRESHOLD_SECONDS env override).

Files:

• registry/wedged_agent.go — IsWedgedAgent pure predicate, StartWedgedAgentMonitor periodic sweep, WedgedThresholdForHTTP public symbol.
• registry/wedged_agent_test.go — 11 unit tests covering the full truth table.
• handlers/workspace.go — get_workspace surfaces a wedged: bool alongside last_outbound_at and last_heartbeat_at (both fetched as separate column-shaped follow-up queries — see follow-up note).
• cmd/server/main.go — onWorkspaceWedged handler (log + broadcast a WORKSPACE_WEDGED event; auto-restart is intentionally NOT wired, see follow-up note).

Follow-up (post-reviewers)

HTTP integration fix (1ea0c718 on top of 788a090a): CR2 12459 + Researcher 12460 caught that the original implementation assumed last_heartbeat_at was in the scanned row of get_workspace, but neither the GET SELECT nor scanWorkspaceRow include that column. The predicate was reading sql.NullTime{} (valid=false) for the heartbeat, so a busy + heartbeating agent with a stale outbound was returned as wedged:true — recreating the false-positive safety concern this PR exists to prevent. The fix fetches last_heartbeat_at as a separate column-shaped follow-up query (mirroring last_outbound_at), surfaces it in the response, and pins the integration boundary with two new handler tests (one wedge case, one busy case).

Auto-recovery (out of scope, per scope discipline): the original issue says "ideally auto-recovers, gated". This PR implements log + WORKSPACE_WEDGED broadcast only. A gated auto-restart is a follow-up: a wedge can mask a slow-but-busy agent, and restarting such an agent loses in-flight state. The initial conservative shape lets operators see the broadcast + the new HTTP flag and decide. The same onWorkspaceWedged handler is the integration point for the follow-up.

Test plan

• 11 new unit tests in registry/wedged_agent_test.go cover the full truth table.
• 2 new handler tests in workspace_test.go pin BOTH directions of the predicate at the HTTP integration boundary: busy + fresh-heartbeat → wedged:false (the canonical legitimate-busy case), busy + stale-heartbeat → wedged:true (the wedge).
• Full registry and handlers test suites pass (~40s).
• go vet clean.

SOP checklist

• Comprehensive testing performed: go build ./... clean; go test ./internal/handlers/... ./internal/registry/... green (40s); go vet ./internal/... clean. The HTTP integration fix adds 2 handler tests pinning both directions of the predicate at the GET boundary, so the false-positive regression cannot recur.
• Local-postgres E2E run: pure Go change, no schema migration. The wedge predicate reads existing active_tasks, last_outbound_at, last_heartbeat_at columns.
• Staging-smoke verified or pending: pending — the monitor's WORKSPACE_WEDGED broadcast is a black-box visible signal; staging-smoke will verify the broadcast path post-merge.
• Root-cause not symptom: the predicate surfaces the actual wedge state (active+stale+stale). The recovery (auto-restart) is intentionally deferred — see scope note above. A wedge can mask a slow turn; restarting blindly loses state. Conservative initial shape.
• Five-Axis review walked: correctness / robustness / security / performance / readability. CR2 + Researcher reviews walked; both addressed in 1ea0c718.
• No backwards-compat shim / dead code added: the wedged field is the new API; the get_workspace response shape gains one boolean and one timestamp. No deprecated field, no migration.
• Memory consulted: feedback_no_single_source_of_truth (the predicate is the single source of truth shared by monitor + HTTP), feedback_follow_dev_sop_phase1_evidence_first (the integration fix was grounded in the actual scanWorkspaceRow / GET SELECT, not assumed from the comment).

fix(health): detect ALIVE-but-wedged agents via active>0 + no outbound + null heartbeat ... 788a090a2e

Closes #3057.

The 2026-06-19 a2a RCA found that a workspace agent can be
'alive-but-wedged': the agent process is up (so the platform's TCP
connect succeeds), but it is hung mid-turn and produces no outbound
A2A, no heartbeats, and (eventually) no progress. The 2026-06-19
incident (Kimi, workspace 6cb8c061) had active_tasks=1 (stuck),
last_outbound_at ~48min stale, heartbeat null/fresh:false — but
status:online was set. The wedge was only caught by MANUAL
inspection of the tuple; the platform never flagged it.

The existing reactive detection (isUpstreamDeadStatus →
auto-restart) only fires on dead-origin HTTP statuses
(502/504/521/522/523/524 + 503-restarting), not on the
wedged-while-TCP-alive case. We need a separate health signal that
combines (active_tasks>0, last_outbound_at stale, last_heartbeat_at
stale).

Fix: a new wedge-detection monitor and a surfaced wedged flag in
get_workspace.

Files:
  - registry/wedged_agent.go: IsWedgedAgent pure predicate,
    StartWedgedAgentMonitor periodic sweep, DefaultWedgedThreshold
    (5m) with WEDGED_AGENT_THRESHOLD_SECONDS env override, and
    WedgedThresholdForHTTP public symbol so the HTTP flag and the
    monitor use the same threshold.
  - registry/wedged_agent_test.go: 11 unit tests covering the full
    truth table (wedge / busy / idle / heartbeat-only / non-positive
    threshold / active=2 / etc.) plus the threshold boundary.
  - handlers/workspace.go: get_workspace surfaces a 'wedged' boolean
    alongside last_outbound_at, computed via the shared
    IsWedgedAgent predicate so the flag and the monitor can never
    disagree.
  - cmd/server/main.go: onWorkspaceWedged handler (log + broadcast a
    WORKSPACE_WEDGED event; auto-restart is intentionally NOT wired —
    it is a follow-up gated on ops review because a wedge can mask a
    slow-but-busy agent and restarting it loses in-flight state).
    StartWedgedAgentMonitor wired with supervised.RunWithRecover,
    same contract as StartHealthSweep / StartHibernationMonitor.

Tests: 11/11 new tests pass; full registry + handlers test suites
pass (40s); go vet clean.

Follow-up intentionally out of scope: gated auto-restart of wedged
workspaces (operator review needed to confirm a wedge != a slow
turn).

5-axis review on head 788a090a:

REQUEST_CHANGES.

1. Correctness / false-positive safety: Get computes the surfaced wedged flag from ws["last_heartbeat_at"], but the workspace GET query / scanWorkspaceRow do not select or populate last_heartbeat_at. That leaves lastHeartbeat invalid for every response, so any workspace with active_tasks > 0 and stale/null last_outbound_at is reported as wedged even if it has a fresh heartbeat. This violates the stated safety property (active>0 + stale outbound + null/stale heartbeat) and can falsely flag legitimately busy agents as wedged. Please fetch last_heartbeat_at for this path and add a handler-level regression test proving fresh heartbeat + stale outbound returns wedged:false.

2. Correctness / requested behavior: the dispatched review request describes this as the durable wedge-detection/auto-recover fix and asks me to review reset/restart idempotency. This PR intentionally wires log + WORKSPACE_WEDGED broadcast only; it does not reset or restart anything. If #3057 requires auto-recovery, the recovery action is missing and cannot be reviewed for idempotency. If detection-only is the intended scope, the PR/title/request should be aligned before merge.

Robustness: the pure predicate is conservative and has useful unit truth-table coverage, but the HTTP integration gap above is not covered. Security: no new auth/data exposure beyond a boolean flag. Performance: 30s polling query is bounded to online/degraded active workspaces; acceptable. Readability: generally clear, though the comment saying last_heartbeat_at is already in the scanned row is currently incorrect.

SOP status: the PR body does not contain the required 7-item SOP checklist, so I did not post any /sop-ack <slug> comments.

5-axis review on head 788a090a.

Correctness: blocker in the surfaced HTTP wedged flag. WorkspaceHandler.Get says last_heartbeat_at is already in the scanned row, but the GET SELECT at workspace-server/internal/handlers/workspace.go:1272-1285 does not select it, and scanWorkspaceRow does not scan/store it (workspace.go:1131-1207). As a result, lastHeartbeat remains invalid at workspace.go:1369-1377, so registry.IsWedgedAgent(...) treats heartbeat as null. A legitimately busy, heartbeating agent with active_tasks>0 and stale/no outbound will be returned as wedged:true, even though the monitor predicate and tests correctly say recent heartbeat should make it NOT wedged. This is exactly the false-positive safety concern for this PR.

Robustness: the pure predicate is conservative (active>0 && outbound stale/null && heartbeat stale/null) and the monitor SQL mirrors it, then re-applies the Go predicate. The current issue is integration drift in get_workspace; add last_heartbeat_at to the row/query or fetch it alongside last_outbound_at, plus a handler test for recent heartbeat + stale outbound => wedged:false.

Security: no new auth boundary issue found; the flag is operational metadata on an existing workspace GET surface.

Performance: the monitor query is narrow enough for the intended sweep. Adding one heartbeat timestamp to the GET path is negligible.

Readability/operability: log+broadcast only is a good initial recovery shape; no auto-restart is wired, so no restart thrash loop in this PR. But the HTTP flag must not disagree with the monitor.

Verification: local Go tests could not be run in this container because go is not installed. SOP ack status: no /sop-ack posted because of the code blocker. Also, the PR body visible through the API does not contain the required 7-item SOP checklist, so I cannot ack individual checklist slugs from the body.

agent-dev-b added 1 commit 2026-06-19 04:34:47 +00:00

fix(health#3057): fetch last_heartbeat_at in get_workspace — the predicate was reading null ... 1ea0c71888

Follow-up to CR2 review 12459 + Researcher review 12460 on PR #3061.

Both reviewers caught the SAME false-positive bug at the HTTP
integration boundary: the original implementation assumed
`last_heartbeat_at` was already in the scanned row of
`get_workspace`, but neither the GET SELECT nor scanWorkspaceRow
include that column. As a result, the wedge predicate's
`lastHeartbeat` argument was always sql.NullTime{} — valid=false
— and the predicate treated heartbeat as 'always null/stale'. A
legitimately busy, heartbeating agent with active_tasks>0 and a
stale/no outbound would be returned as wedged:true, even though
the IsWedgedAgent truth table (and the unit tests) correctly say
a fresh heartbeat must make it NOT wedged. This recreated the
exact false-positive safety concern this PR exists to prevent.

Fix: fetch last_heartbeat_at as a separate column-shaped
follow-up query in the GET handler, mirroring the existing
last_outbound_at follow-up query. Surface it in the response
so operators can see the value the predicate consumed. The
predicate input is now correct at the HTTP boundary, and the
flag agrees with the monitor.

Tests:
- TestWorkspaceGet_Wedged_FreshHeartbeatStaleOutbound: busy
  agent (active=1) with FRESH heartbeat + STALE outbound →
  wedged:false. Pins the canonical 'legitimately busy' case
  that was broken by the previous version.
- TestWorkspaceGet_Wedged_StaleHeartbeatStaleOutbound: busy
  agent with STALE heartbeat + STALE outbound → wedged:true.
  Companion test pinning the wedge direction at the HTTP
  integration boundary, so a future refactor that drops the
  heartbeat fetch will fail both tests.

Full handler test suite passes (38s); go vet clean. 2 files,
+166/-11 on top of 788a090a.

SOP checklist to be added to the PR body in a follow-up
commit (both reviewers flagged the missing checklist).

5-axis re-review on head 1ea0c718:

APPROVED.

Correctness: my prior 12459 false-positive finding is resolved. Get now fetches last_heartbeat_at with a separate column query, stores it in the response, and passes the real sql.NullTime into registry.IsWedgedAgent alongside active_tasks and last_outbound_at. The new handler regression test covers the important legitimate-busy case (active_tasks=1, stale outbound, fresh heartbeat) and asserts wedged:false; the companion stale-heartbeat test asserts the actual wedge still returns wedged:true.

Robustness: the predicate remains conservative and excludes active agents with fresh heartbeat; external runtimes are still excluded from the monitor query. The monitor action is log/broadcast only, so there is no unsafe auto-kill/reset path in this PR. Security: exposes a boolean and heartbeat timestamp for workspace status; no new auth or input trust boundary. Performance: GET adds one small single-row timestamp query, matching the existing last_outbound_at shape; monitor query is scoped to online/degraded active non-external workspaces. Readability: comments now correctly describe the separate heartbeat fetch and the scope note makes auto-restart explicitly follow-up.

CI visible at review time: several code checks are still pending, and template-delivery-e2e is currently failing; this approval is for the reviewed code/diff, not a statement that the merge gate is green.

Fresh re-review on head 1ea0c718.

5-axis review:

• Correctness: prior false-positive blocker is resolved. WorkspaceHandler.Get now fetches last_heartbeat_at separately (workspace-server/internal/handlers/workspace.go:1368-1375) and passes the real sql.NullTime into registry.IsWedgedAgent with active_tasks and last_outbound_at (workspace.go:1386-1387). The new handler tests pin both directions: active + stale outbound + fresh heartbeat => wedged:false, and active + stale outbound + stale heartbeat => wedged:true.
• Robustness: the pure predicate remains conservative (active_tasks > 0, outbound stale/null, heartbeat stale/null), the monitor reuses the predicate after SQL filtering, and this PR still avoids auto-restart, so false positives do not kill working agents.
• Security: no new auth boundary or secret exposure. last_heartbeat_at is operational metadata consistent with the existing surfaced last_outbound_at/status fields.
• Performance: two small follow-up timestamp queries on GET are acceptable for this endpoint; monitor sweep remains narrow.
• Readability: comments now accurately describe the separate heartbeat fetch and why it is load-bearing.

Verification: local Go tests could not be run in this container because go is not installed. I reviewed the diff and regression tests directly; dispatch notes code CI is still pending.
