[Exchange] CI: Backfill evidence_for/evidence_against with PubMed citations

> ## Continuous-process anchor

> This spec describes an instance of one of the retired-script themes

>
> 1. The "Design principles for continuous processes" section of that
> atlas — every principle is load-bearing. In particular:
> - LLMs for semantic judgment; rules for syntactic validation.
> - Gap-predicate driven, not calendar-driven.
> - Idempotent + version-stamped + observable.
> - No hardcoded entity lists, keyword lists, or canonical-name tables.
> - Three surfaces: FastAPI + orchestra + MCP.
> - Progressive improvement via outcome-feedback loop.
> 2. The theme entry in the atlas matching this task's capability:
> AG3 (pick the closest from Atlas A1–A7, Agora AG1–AG5,
> Exchange EX1–EX4, Forge F1–F2, Senate S1–S8, Cross-cutting X1–X2).
> 3. If the theme is not yet rebuilt as a continuous process, follow

Work Log

2026-04-04 03:32 PT — Slot 1

• Status: VERIFIED — CI Backfill is working correctly
• Found backfill_evidence_ci.py already implemented at project root
• Script uses pubmed_enrichment.py (search_pubmed, get_article_info, build_search_terms)
• DB analysis: 211 hypotheses total, 0 missing evidence_for arrays
• Evidence quality check (real hypotheses only):

- All 204 real hypotheses have >=10 evidence_for items
- All real hypotheses have >=3 evidence_against items

• 7 test hypotheses (hyp_test_*) have thin evidence but lack target_gene, so PubMed queries can't be constructed — these are test data, not real content
• Ran backfill_evidence_ci.py: correctly skips test hypotheses, no new citations found (expected)
• API: /api/status returns 200 with hypotheses=211, analyses=62, edges=22129
• Site returns 302 redirect (healthy)
• Conclusion: CI backfill pipeline is functioning. No code changes needed. Script runs every 6h as recurring task.

2026-04-04 10:37 UTC — Slot 1

• Re-verified evidence arrays status
• All 211 hypotheses have both evidence_for and evidence_against populated (0 missing)
• Sampled 5 random hypotheses — all have proper JSON with PMIDs and claims
• Result: CI check passed — no backfill needed.

2026-04-04 (Slot 2) — Evidence Backfill CI

• DB state: 195 hypotheses, 7 with empty evidence_for AND evidence_against
• Ran backfill_missing_evidence.py: updated all 7/7 with PubMed citations

- h-6f1e8d32: Cardiovascular-Neuroinflammatory (4 for, 3 against)
- h-6880f29b: IGFBPL1-Mediated Microglial (4 for, 2 against)
- h-f19b8ac8: Complement-Mediated Synaptic Protection (4 for, 3 against)
- h-69bde12f: APOE4-Lipid Metabolism Correction (4 for, 1 against)
- h-6f21f62a: Microbiota-Microglia Axis Modulation (4 for, 3 against)
- h-ea3274ff: TREM2-P2RY12 Balance Restoration (4 for, 3 against)
- h-8f9633d9: Perinatal Immune Challenge Prevention (4 for, 3 against)

• Post-run: 0 hypotheses with empty evidence arrays
• Result: ✅ CI complete — 7 new hypotheses backfilled with evidence. All 195 hypotheses have citations.

2026-04-04 04:48 PDT — Slot 11

• Pulled latest origin/main into worktree branch before execution.
• Reviewed backfill_evidence_ci.py and pubmed_enrichment.py implementation paths for PubMed-backed evidence top-up logic.
• Baseline DB audit (postgresql://scidex): total=180, thin(<3 for/<2 against)=54.
• Executed recurring CI job: timeout 300 python3 backfill_evidence_ci.py.
• Run result: processed batch of 10, enriched 7 hypotheses (Done: 7/10 hypotheses enriched).
• Post-run DB audit: thin reduced from 54 to 47.
• API check: curl http://localhost:8000/api/status returned 200 with valid JSON.
• Page checks: / 302, /exchange 200, /gaps 200,

2026-04-12 — Recurring CI Run

• DB audit: total=364, missing evidence_for=0, missing evidence_against=0, thin=0
• Ran backfill/backfill_evidence_ci.py: 1 hypothesis found thin (test hypothesis hyp_test_*), 0 enriched (expected — test hyp lacks target_gene)
• All 364 real hypotheses have sufficient evidence arrays (≥3 for, ≥2 against)
• API: /api/status returned 200, hypotheses=364
• Result: ✅ CI check passed — no backfill needed, evidence coverage healthy/graph 200, /analyses/ 200, /atlas.html 200, /how.html 301.
• Link check: timeout 300 python3 link_checker.py completed; report indicates pre-existing site-wide broken links (862 refs across 1105 pages), not introduced by this task's evidence backfill run.
• Result: recurring Exchange evidence backfill executed successfully and improved dataset coverage for this cycle.

2026-04-12T23:xx UTC — Recurring CI Run (task:33803258-84bd-4bde-873b-740f1de9d1c3)

• DB audit: total=373, thin(<3 for/<2 against)=1 (only hyp_test_0a572efb — test hypothesis, no target_gene)
• Ran backfill/backfill_evidence_ci.py: correctly skipped test hypothesis, 0 enriched (expected)
• All 372 real (non-test) hypotheses have ≥3 evidence_for and ≥2 evidence_against citations
• API: /api/status returned 200, hypotheses=373
• Result: ✅ CI check passed — evidence coverage healthy, no backfill needed

2026-04-04 05:29 PT — Slot 2

• Started recurring run for task 33803258-84bd-4bde-873b-740f1de9d1c3 and validated implementation paths in backfill_evidence_ci.py/pubmed_enrichment.py.
• Executed timeout 300 python3 backfill_evidence_ci.py successfully.
• Backfill run processed 10 hypotheses and enriched 7 (Done: 7/10 hypotheses enriched), including top-ups to both evidence_for and evidence_against.
• Evidence coverage snapshot after run (181 total hypotheses):

- evidence_for < 3: 14
- evidence_against < 2: 37
- empty evidence_for: 7
- empty evidence_against: 27

• Endpoint checks:

- http://localhost:8000/api/status → 200

• Pages: /=302, /exchange=200, /gaps=200, /graph=200, /analyses/=200, /atlas.html=200, /how.html=301
• Service health check: scidex status reports API/nginx/neo4j active.
• Link check executed with timeout: timeout 300 python3 link_checker.py completed; current run reports a systemic status-0 crawl issue (existing environment-level checker behavior), not a regression from this task's code path.
• Result: recurring CI backfill run completed with new citation enrichment and no code changes required.

2026-04-04 06:14 PDT — Slot 3

• Reviewed current implementation in backfill_evidence_ci.py and pubmed_enrichment.py before execution.
• Baseline DB audit (postgresql://scidex): total=181, thin_for(<3)=6, thin_against(<2)=25.
• Executed: timeout 300 python3 backfill_evidence_ci.py (timed run as required); run enriched multiple hypotheses before timing out under intermittent DB lock contention.
• Post-run DB audit: total=181, thin_for(<3)=4, thin_against(<2)=15 (net improvement this cycle).
• Verification:

- curl -s http://localhost:8000/api/status | python3 -m json.tool returned valid JSON.
- Page checks on port 8000 passed initially: / 302, /exchange 200, /gaps 200, /graph 200, /analyses/ 200, /atlas.html 200, /how.html 301.
- timeout 300 python3 link_checker.py was executed; crawl reported intermittent localhost timeouts/connection resets while API briefly entered deactivating.

• Waited 2 minutes and re-checked: API recovered to active; http://localhost:8000/ returned 302; /api/status returned valid JSON.
• Result: recurring Exchange evidence backfill made measurable coverage gains and service health recovered after transient churn.

• DB audit (PG): total=731 real hypotheses, 6 with thin evidence (target_gene set but ef<3 or ea<2)
• Diagnosed: backfill/backfill_evidence_ci.py UPDATE used ? placeholders (SQLite) with psycopg (requires %s) — caused timeout on DB execute
• Fixed: replaced conn.execute("UPDATE ... SET evidence_for=?, ...", (json.dumps(...), ...)) with %s and db.cursor().execute() pattern
• Also: removed in-memory filtering (WHERE now filters directly), removed sqlite3 import, removed DB_PATH sentinel, simplified main()
• Ran: 1/6 hypotheses enriched — h-var-73d2ff30c1 (SLC16A1/MCT1 Metabolic): +3 for, +2 against
• Remaining 5 still thin but PubMed returned no new citations (queries too specific or gene names complex)
• API: /api/status → 200, pages: / 302, /exchange 200, /gaps 200
• Committed fix and pushed to branch orchestra/task/33803258-backfill-evidence-for-evidence-against-w
• Result: CI PASS — 1 hypothesis enriched, script fixed for PostgreSQL, pushed.
• DB audit (PG): total=747, real=731, thin_for(<3)=110, thin_against(<2)=114
• Ran backfill/backfill_evidence_ci_pg.py batch 1: 4/10 enriched:

• Found PostgreSQL compatibility bug in scidex/forge/tools.py _upsert_cached_paper: was using SQLite syntax (PRAGMA, INSERT OR REPLACE, datetime()) on a PostgreSQL connection via the shim
• Fixed scidex/forge/tools.py to use PostgreSQL: ON CONFLICT DO UPDATE instead of INSERT OR REPLACE, NOW() instead of datetime(), removed invalid PRAGMA journal_mode
• Second batch timed out at 300s (PubMed API rate limiting: 3s pre-delay + 2s/article); no SQLite errors after fix
• API: /api/status → 200 (hypotheses=747, edges=711775)
