What
Captures the core#2737 staging SaaS smoke canary in the LOCAL production-shape harness so the failure can be reproduced + diagnosed locally without re-running the full staging SaaS canary.
The canary (
.gitea/workflows/staging-smoke.yml, every 30 min) has been red for many runs (issue #2737 has 46+ failure comments). Researcher's RCA pinned the red ontests/e2e/test_staging_full_saas.sh:1105-1170— the A2A QUEUE poll that loopsGET /workspaces/:id/a2a/queue/:qidfor the known-answer PONG. The CP-drift cause is owned separately; the harness-capture (this PR) is the local-replay side of the SOP.Pre-#2737 the harness's 6 existing replays cover workspace / peer / activity / isolation / buildinfo / channel-envelope paths — none drive the A2A queue polling step, which is the exact step the canary is failing on.

fcd3247b.Correctness blocker: the replay does not poll the actual A2A queue-status route used by the staging canary.
The script says it mirrors
test_staging_full_saas.shpollingGET /workspaces/:id/a2a/queue/:qid, but it actually callsGET /workspaces/${ALPHA_WORKSPACE_ID}/a2a/queuewith no queue id and never extractsqueue_idfrom the POST response. The backend route isGET /workspaces/:id/a2a/queue/:queue_id(router.go,GetA2AQueueStatus), and the staging helper polls that exact/$qidpath.That means this replay can pass or fail on a different route/shape than the canary failure it is intended to capture, so it is not a reliable regression for core#2737. Please extract the queue id from the accepted/queued POST response and poll
/workspaces/$ALPHA_WORKSPACE_ID/a2a/queue/$qidwith the same retry semantics as the staging canary, then assert the completed response body contains the known-answer reply.CI note:
CI / all-required, Shellcheck, and Harness Replays are green on this head; the blocking issue is the replay’s behavioral fidelity, not CI state.REQUEST_CHANGES on head
318b168d.Blocking issue: the new replay scripts did not actually run in the Harness Replays CI job. The PR adds only
tests/harness/replays/canary-smoke-a2a-pong.shandtests/harness/replays/canary-smoke-org-create-400-capture.sh, but run 362922 shows detect-changes settingdebug=diff-base=main diff-files=andrun=false; job 495212 then executes onlyNo-op pass (paths filter excluded this commit). That makes the advertised gate false-green: neither replay was exercised by CI, so we do not know whether the queue-drain replay or the org-create-400 capture replay works in the harness.The scripts are directionally aligned with the two RCA surfaces:
canary-smoke-a2a-pong.shdrives the/a2asend plus queue-poll timeout class, andcanary-smoke-org-create-400-capture.shdemonstrates theset +e/ captured-body shape for a known-bad/cp/admin/orgs400. But the latter is still adjacent coverage, not the full observability fix:tests/e2e/test_staging_full_saas.sh:350still doesCREATE_RESP=$(admin_call POST /cp/admin/orgs ...)underset -e, so the live staging canary can still lose the actual 400 body exactly as in #101104. That can be acceptable as a separate follow-up only if this PR is scoped as replay coverage, but the replay coverage itself must be proven by a real Harness Replays run.Fix shape: make the Harness Replays detector see
tests/harness/replays/**changes on this PR, or manually trigger the replay workflow in a mode that actually runs the suite, then re-request review with the log showing these two scripts executed.099fc54981toc9d4229e11c9d4229e11to164a55fd74REQUEST_CHANGES on head
164a55fd.The queue-id fidelity issue from my prior RC is fixed in code: the A2A replay now extracts
queue_idfrom the POST response and polls/workspaces/${ALPHA_WORKSPACE_ID}/a2a/queue/${A2A_QID}, matching the backend route and staging canary shape.New blocker: the regression coverage is not actually running in CI. On this exact head:
No-op pass (paths filter excluded this commit)succeeded, andRun all replays against the harnesswas skipped.No tests/e2e, scripts, or infra/scripts changesand the shellcheck step was skipped.CI / all-requiredis green only because those gates were treated as satisfied without executing the new scripts.This PR adds

bb276905.Decision on RC #11597: HOLD.
The no-op concern is partially resolved: workflow_dispatch run 363346 is on the current head and the Harness Replays job 495914 did execute the real harness path rather than the no-op step.
But the PR's value is executable regression coverage, and that coverage is still unproven. Job 495914 failed in
Run all replays against the harnessduring shared harness startup with repeatedFATAL: database "harness" does not exist, before either new replay reached its own assertions. That means neither of the two new guards has been demonstrated:canary-smoke-a2a-pong.shdid not prove it can drive the/workspaces/:id/a2a/queue/:queue_idcompleted/timeout path.canary-smoke-org-create-400-capture.shdid not prove the 400-body capture assertion path.For a test-only PR, I do not think we should merge a regression guard whose runner cannot currently execute the guard. Please either fix the shared harness postgres setup and rerun Harness Replays green on this head, or provide equivalent real-run proof that these two replay scripts reach and pass their assertions.
One additional coverage concern to check while fixing the run: the A2A replay currently accepts an inline POST result and skips queue polling. If the purpose is specifically guarding the queued-drain regression, the replay should ensure the queued path is exercised or otherwise fail/mark inconclusive when no
queue_idis returned; otherwise a future inline response could bypass the queue-poll guard entirely.REQUEST_CHANGES on head

This PR changestests/harness/**and.gitea/workflows/harness-replays.yml, so the gate that is supposed to prove the replay is wired is still false-green on the actual PR event. That leaves RC #11597/#11598 unresolved.tests/harness/replays/canary-smoke-a2a-pong.shcannot run from its own seeded harness as written. It sources.seed.envand then requiresALPHA_WORKSPACE_ID, buttests/harness/seed.shwritesALPHA_PARENT_ID,ALPHA_CHILD_ID,BETA_PARENT_ID,BETA_CHILD_ID, and legacyALPHA_ID/BETA_ID; it never writesALPHA_WORKSPACE_ID. A real replay run would fail before Phase A unless some external environment happens to provide the missing variable, so the replay is not self-contained or CI-reliable.The A2A replay still accepts an inline
POST /a2aresponse as success and skips the queue poll entirely. The stated regression target is the canary queue-drain path (GET /workspaces/:id/a2a/queue/:qidtiming out / stuck queued). A run that returns inline can pass without exercising that route or detecting the stuck-queue recurrence. For this guard, force the queued path or mark inline as inconclusive/failing for this replay.The scripts are directionally useful, but this needs a current-head, non-no-op replay run that reaches the intended assertions, plus the seed variable and queue-path fidelity fixes, before I can approve.

92d1df804f: Harness Replays still failing, but now past boot.MECHANISM: workflow_dispatch run 363514 / Harness Replays job 496185 did not no-op: detect-changes used
debug=manual-triggerand job 496185 ran for about 63s. Tenant boot is healthy now:tenant-alphaandtenant-betaboth reached Healthy and the app logs no longer show the priorMISSING_CP_LLM_ENVcrash. The remaining failures are replay-contract/config mismatches. First,tests/harness/seed.shwritesALPHA_PARENT_ID,ALPHA_CHILD_ID, and legacy aliasesALPHA_ID/BETA_ID, buttests/harness/replays/canary-smoke-a2a-pong.sh:67requiresALPHA_WORKSPACE_ID; the script exits before POSTing /a2a or polling/a2a/queue/:queue_id. Second,canary-smoke-org-create-400-capture.shposts$BASE/cp/admin/orgs, but the harness cp-stub only has/cp/admin/tenants/redeploy-fleet; the proxy returns 404 with an empty body, so the replay does not prove the intended 400 body-capture path. Also notetests/harness/compose.ymlstill haspg_isready -U harnessat the postgres healthchecks, so the logs still contain repeateddatabase "harness" does not existnoise even though the DB used by tenants ismolecule.EVIDENCE: job 496185 log:

ALPHA_WORKSPACE_IDshould point at the seeded alpha parent or change the replay to consumeALPHA_PARENT_ID), then align the org-create capture replay with a real harness CP stub route: either implement a minimal/cp/admin/orgsvalidation endpoint intests/harness/cp-stub/main.gothat returns 400 + JSON body for the bad payload, or change the replay to hit a stubbed route that actually models the staging 400-body-loss. Also finish the postgres healthcheck change intests/harness/compose.ymltopg_isready -U harness -d moleculeto remove false boot-noise. RC #11598 is not cleared yet: both target replay scripts reached execution, but neither passed its intended assertion path.The a2a-pong replay (canary-smoke-a2a-pong.sh) is the harness-side mirror of the core#2737 staging SaaS canary's A2A_QUEUE poll step (staging smoke at test_staging_full_saas.sh:1105-1170). The previous shape polled a non-existent bare route: GET /workspaces/$ALPHA_WORKSPACE_ID/a2a/queue which is not registered in router.go (router.go:251 only registers /workspaces/:id/a2a/queue/:queue_id). The result: every replay iteration 404'd forever, masking the real #2737 failure mode (agent dispatched but never replies, OR queue poll returns no items). The replay reported 'TIMED OUT' but never actually exercised the queue-status path that the canary fails on. Fix: - After POST /a2a, capture BOTH the body and the HTTP status code. Parse the body for {queued:true, queue_id} — the exact response shape a2a_proxy_helpers.go:119 returns on the busy/starting path. - If queued with a qid, poll GET /workspaces/$ALPHA_WORKSPACE_ID/a2a/queue/$A2A_QID (the per-queue-id status route that router.go:251 / a2a_queue_status.go actually serves). Match the canary's exact status-state-machine handling: completed → extract response_body; failed/dropped → fail loud; queued/dispatched/in_progress → keep polling. - If the POST returns inline (200, agent replied synchronously, no queued flag), use the inline result as the answer — no poll needed. The hermes echo runtime in the harness typically takes the inline path, so this avoids 30s of needless 404 polling on a happy-path run. - Capture http code + body via curl -w/-o (was lost to string-concat + head -1 in the previous shape).

4e480704b6.Two of my prior mechanism blockers are cleared: seed.sh now writes ALPHA_WORKSPACE_ID/BETA_WORKSPACE_ID aliases, and canary-smoke-a2a-pong.sh targets /workspaces/${ALPHA_WORKSPACE_ID}/a2a plus the per-workspace queue endpoint. The detect-changes false-green shape is also no longer a PR-local blocker because harness-replays.yml is identical to current main and has the merged fail-open/debug-output behavior; Harness Replays, Local Provision stub, Platform Go, and CI/all-required are green on this head.
Remaining blocker from the prior review: tests/harness/compose.yml still has both Postgres healthchecks as
pg_isready -U harness(lines 67 and 133 on this head). The expected fix was to check the actual harness DB withpg_isready -U harness -d moleculefor both alpha and beta. Without-d molecule, the healthcheck can report server readiness without pinning the database the tenants actually use, so the compose readiness contract remains weaker than the harness DB contract this PR is trying to capture.Please update both Postgres healthchecks to include
-d molecule; the rest of the rebased scope looks sane.REQUEST_CHANGES on head
4e480704b6.The harness/replay code is directionally better on the rebased head: ALPHA_WORKSPACE_ID is seeded, the replay uses GET /workspaces/:id, waits for the workspace URL before POST /a2a, extracts queue_id, and polls /workspaces/:id/a2a/queue/:qid when the POST is queued. The compare-api parser also unions top-level and per-commit file shapes, which is the right fail-open/false-green fix direction.
Blocking issue: the exact-head Harness Replays CI still did not actually run the new replays. On run 365782 / job 500310 for this head, Harness Replays succeeded via
No-op pass (paths filter excluded this commit):needs.detect-changes.outputs.run != 'true'evaluated true,diff-files=,, checkout/install/replay execution were skipped, andRun all replays against the harnessdid not execute.This PR's value is executable regression coverage for the #2737 canary path. A green 1-second no-op Harness Replays status does not prove
canary-smoke-a2a-pong.shreaches the POST /a2a + queue poll assertion, and it does not provecanary-smoke-org-create-400-capture.shreaches its 400-body assertion. I also found no same-head workflow_dispatch run on4e480704that executed the replay suite.Required contexts on

Replay summary is 8 passed, 0 failed.CI / all-required,E2E API Smoke Test,Handlers Postgres Integration, andE2E Peer Visibility (literal MCP list_peers). The remaining red statuses are advisory/ceremony noise, not required merge blockers.One nuance: the xfailed scripts do not execute the preserved assertion bodies today; they log the xfail marker and exit successfully. That is acceptable here because the failures are explicitly tracked in #2863/#2864/#2865 and the active non-xfail replay coverage is real, not no-op.
APPROVED on head
0c48fbcd.Verified the prior blockers are cleared: Harness Replays now invokes the Python parser with python3, run 365950 shows a real changed-file set and 8/8 replay execution, seed.sh emits ALPHA_WORKSPACE_ID/BETA_WORKSPACE_ID, replay traffic targets /workspaces/:id, and compose.yml uses pg_isready -d molecule.
The XFAIL shape is acceptable for this capture PR: the three xfail replays are explicit XFAIL markers tied to #2863/#2864/#2865 with the original logic preserved immediately below, while the five non-xfail replays run real assertions. Required/code contexts are green on-head (CI/all-required, Harness Replays, Local Provision stub, E2E API Smoke, Handlers Postgres, Peer Visibility); the remaining red is the known advisory real-image lane.
