From fcd3247bdd5967d6eb13bc8ce8ec90515a280228 Mon Sep 17 00:00:00 2001 From: "Molecule AI Dev Engineer B (MiniMax)" Date: Sun, 14 Jun 2026 04:19:21 +0000 Subject: [PATCH 1/3] test(harness): capture core#2737 canary A2A smoke flow in local replay MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The staging SaaS smoke canary (staging-smoke.yml, every 30 min) has been red for many runs (issue #2737 has 46+ failure comments). Researcher's RCA pinned the red on tests/e2e/test_staging_full_saas.sh:1105-1170 — the A2A QUEUE poll that loops GET /workspaces/:id/a2a/queue/:qid for the known-answer PONG. The CP-drift cause is owned separately; the harness-capture (this PR) is the local-replay side of the SOP. This replay captures the canary's A2A round-trip against the LOCAL production-shape harness (cf-proxy + canvas-proxy + cp-stub + tenant images from Dockerfile.tenant), so the failure can be reproduced and diagnosed locally without re-running the full staging SaaS canary. 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. Phases: A. Liveness — alpha /health + seeded workspace resolve. B. Mint a per-workspace bearer (via /admin/workspaces/:id/tokens, matching the canary's auth shape) and POST /a2a with a known-answer payload (default text: "pong"), carrying the X-Molecule-Org-Id + X-Workspace-ID headers the production-shape cf-proxy + TenantGuard expect. C. Poll GET /workspaces/:id/a2a/queue up to POLL_TIMEOUT_SECS (default 30s, matching the staging canary's per-poll cap) for the messageId we sent. Same shape as test_staging_full_saas.sh:1105-1170. D. Assert the queue poll found the PONG (non-empty body). Negative result = the core#2737 failure shape (queue poll returns no items forever) reproduced locally. Failure modes this catches that unit tests don't (matching the staging canary's surface): - 524 from cf-proxy when the proxy / agent-bridge is starved - WS starvation on long synchronous turns - A2A QUEUE poll returns no items forever (the symptom pinned in #2737 at test_staging_full_saas.sh:1105-1170) - TenantGuard middleware path (production-shape, not unit-mock'd) - The full canvas -> proxy -> A2A handler wire, not the handler signature alone Required env (set by tests/harness/up.sh + seed.sh): BASE, ALPHA_ADMIN_TOKEN, ALPHA_ORG_ID, ALPHA_WORKSPACE_ID (seeded by seed.sh; .seed.env read by source). Optional env: POLL_TIMEOUT_SECS default 30 KNOWN_ANSWER_TEXT default 'pong' CI gate: the .gitea/workflows/harness-replays.yml workflow auto-runs every replay under tests/harness/replays/ on push/PR (paths filter on workspace-server/, canvas/, tests/harness/, .gitea/workflows/harness-replays.yml). A regression that breaks the canary's A2A queue polling will now also break this replay, surfaced as a CI failure alongside the canary red. Local validation: bash -n tests/harness/replays/canary-smoke-a2a-pong.sh -> clean (exit 0) chmod +x tests/harness/replays/canary-smoke-a2a-pong.sh End-to-end run requires the harness (tests/harness/up.sh + seed.sh); cannot validate in this session (no Docker access in the agent environment). CI gate is the authoritative validator.

Researcher RCA #101104 (2026-06-14T04:07:25Z): the staging script's admin_call helper uses `curl --fail-with-body` so a non-2xx POST /cp/admin/orgs returns the body to stdout but exits 22 — and under set -e the script exits before reaching the raw-body diagnostic block. The 400 body is silently lost; future 400s require forensic log diffing to classify. This replay captures the failure shape locally against the harness's CP stub: POST /cp/admin/orgs with a known-bad payload (missing owner_user_id), bypass the admin_call helper so the body is captured, assert the response is a 4xx with a non-empty parseable JSON body. If the harness's CP stub ever regresses to returning an empty body or a 5xx for a bad payload, this replay surfaces it. The recommended staging fix (per Researcher #101104) is to mirror this capture shape in tests/e2e/test_staging_full_saas.sh — temporarily disable set -e around admin_call, capture the body to a file, parse + assert. The replay's phase 4 prints the recommended pattern so the staging fix has a copy-paste template. Pair coverage on #2737: - A2A-queue-drain replay (prior commit) — catches the downstream "row stuck at status=queued" failure pinned in the Researcher's earlier RCA. - org-create-400-body capture (this commit) — catches the upstream "CP returns 400, body lost under set -e" failure pinned in Researcher RCA #101104. CI gate: .gitea/workflows/harness-replays.yml auto-runs every replay under tests/harness/replays/ on push/PR (paths filter on workspace-server/, canvas/, tests/harness/, .gitea/workflows/harness-replays.yml). A regression that breaks either replay surfaces as a CI failure alongside the canary red. Local validation: bash -n tests/harness/replays/canary-smoke-org-create-400-capture.sh -> clean (exit 0) chmod +x set End-to-end run requires the harness (tests/harness/up.sh + seed.sh); cannot validate in this session (no Docker access in the agent environment). CI gate is the authoritative validator.

Detached WS-delivery test (the contract-critical gap) NEW: TestProxyA2A_CanvasCapAndQueue_DetachedResultDelivery pins the contract-critical >budget result-delivery path end-to-end. The cap-and-queue returns {status:"queued"} (202 Accepted with task_id in the #2751 expansion) when the agent's turn outlives the budget, but the queued ack is ONLY USEFUL if the actual agent result subsequently lands on the A2A_RESPONSE WS broadcast. This test forces the queued path (50ms budget, 500ms agent), captures the eventual broadcast, and asserts: 1. workspace_id == "ws-deliver" (correct routing) 2. message_id == "msg-deliver-001" (canvas can correlate to the original send) 3. response_body.result.reply == "detached-delivery-reply" (the actual agent reply, NOT empty / NOT placeholder — the contract-critical "did the agent's real work actually arrive?" assertion) 4. duration_ms > 50 (proves the queued path actually fired; the sync path would duration ~0 since the handler returned at the budget, not after the agent) Returning {status:"queued"} is necessary but not sufficient — a regression that broadcast an empty body or wrong workspace_id with the right message_id would leave the canvas with no result to render. This test closes the gap. Distinct from TestProxyA2A_CanvasCapAndQueue_EndToEndContract: that test asserts message_id + response_body content; this test additionally asserts duration_ms > budget (proves the queued path actually fired, not the sync path) and verifies workspace_id routing. ## 2. Budget-hybrid comment fix (the contradictory wording) Fixed a2a_proxy.go cap-and-queue block + canvasA2ASyncBudget doc to describe the BUDGET-HYBRID behavior (sync under budget, queued+WS over budget) instead of the contradictory 'held for the whole turn' / 'cap-and-queue synchronous wait' wording. The code is a budget-hybrid (NOT always-async, NOT always-sync), and the comments now match the actual implementation. ## 3. (CR2 #11543 default-ON behavioral test) — already exists; documented The 'unset env, short turn, assert SYNC reply not queued' test is conceptually the same as the existing TestCanvasA2ASyncBudget_DefaultIs90s (unit test on canvasA2ASyncBudget() — the function whose value the if-block guards on). That unit test directly catches a regression of the default to 0 (legacy always-sync), which would re-expose canvas to the 524+WS-starvation class. The unit test IS the behavioral guard at the function level; an integration variant cannot distinguish default=0 from default=90s for a 2-3s turn (both return the sync reply — see prior turn's analysis).
