[Agora] Add PubMed evidence to 11 hypotheses lacking citations blocked

Goal

Attach real PubMed-backed evidence to hypotheses whose evidence_for field is empty. This improves scientific grounding and prevents debate, ranking, and market workflows from relying on unsupported claims.

Acceptance Criteria

Approach

Select hypotheses with empty evidence_for, prioritizing active and high-impact rows.

Use paper_cache.search_papers or paper_cache.get_paper to find relevant PubMed evidence.

Add concise supporting evidence with citation identifiers and caveats.

Verify the updated evidence fields and remaining backlog count.

Work Log

2026-04-20 - Quest engine template

• Created reusable spec for quest-engine generated hypothesis evidence tasks.

2026-04-21 12:28:03Z - Watchdog repair b209ba9b

• Investigated abandoned task 030034d6-752e-4ac9-9935-36489c7ec792.
• Found 43 hypotheses with empty evidence_for, but all 43 are archived placeholder rows titled [Archived Hypothesis]; there are 0 active/non-placeholder hypotheses requiring PubMed evidence.
• Dry-ran scripts/add_pubmed_evidence.py --dry-run --limit 5 and confirmed it would query the literal placeholder title and attach the same unrelated PMIDs to archived rows.
• Plan: exclude archived placeholders from quest-engine backlog counts and PubMed backfill selection, store structured evidence objects, and restore the missing tested backfill helper module.

2026-04-21 12:32:30Z - Watchdog repair result

• Updated quest-engine evidence backlog detection to ignore archived placeholder hypotheses.
• Hardened scripts/add_pubmed_evidence.py so dry runs and live runs ignore archived placeholders and write structured PubMed evidence objects instead of bare PMID arrays.
• Restored scripts/backfill_evidence_pubmed.py for the existing unit tests and PostgreSQL-aware backfill helper behavior.
• Verified: python3 scripts/add_pubmed_evidence.py --dry-run --limit 5 reports 0 actionable hypotheses and 43 archived placeholders ignored.
• Verified: quest_engine.discover_gaps(get_db()) no longer emits the hypothesis-pubmed-evidence gap for the archived placeholder backlog.
• Tested: pytest -q tests/test_backfill_evidence_pubmed.py -> 18 passed; python3 -m py_compile scripts/add_pubmed_evidence.py scripts/backfill_evidence_pubmed.py quest_engine.py passed.

2026-04-22 13:21:27Z - Verification e967d229

• Verified: python3 scripts/add_pubmed_evidence.py --limit 5 shows 0 actionable hypotheses needing evidence.
• All 43 empty-evidence rows are [Archived Hypothesis] placeholders (archived status) — not valid enrichment targets.
• Ran live update on h-a2b3485737 (CAPN1/CAPN2, score=0.4199, status=proposed): 5 PubMed PMIDs attached with structured evidence ({pmid, doi, claim, source, year, url, strength, caveat}).
• Non-placeholder, non-archived hypotheses with empty evidence_for: 0 (target met).
• Non-placeholder hypotheses with evidence_for populated: 874 (confirmed via SELECT COUNT(*)).
• Conclusion: task acceptance criteria already met; no additional enrichment needed.

Already Resolved — 2026-04-23 05:00:00Z

• Evidence: commit 5eb210854 merged to main; top 25 hypotheses by composite_score all have non-empty evidence_for (verified via DB query). Sample PMIDs verified via paper_cache.get_paper(): 41491101, 41530860, 41714746, 41804841 — all return real papers. All 43 empty-evidence rows are [Archived Hypothesis] placeholders.
• Task ID: d02ec580-83c8-4bc0-8495-17a069138c6a
• Acceptance criteria: satisfied — 1123/1166 hypotheses have evidence; the 43 without are archived placeholders correctly excluded.

2026-04-25 19:01:28Z - Live enrichment task:316fc918-80c1-4cff-a85f-72b226d0d18a

• Before: 7 active non-archived hypotheses had empty evidence_for; 43 archived placeholders ignored.
• Enriched all 7 with PubMed evidence via scripts/add_pubmed_evidence.py --limit 20.
• Hypotheses updated: h-e7e1f943 (NLRP3/CASP1), h-ee1df336 (GLP1R/BDNF), h-6c83282d (CLDN1/OCLN), h-74777459 (SNCA/HSPA1A), h-2e7eb2ea (TLR4/SNCA), h-f9c6fa3f (AHR/IL10), h-7bb47d7a (TH/AADC).
• Each received 5 structured PubMed entries ({pmid, doi, claim, source, year, url, strength, caveat}).
• After: active non-archived hypotheses with empty evidence_for = 0; with evidence populated = 1144.

2026-04-25 19:07:25Z - Thin-evidence enrichment task:316fc918-80c1-4cff-a85f-72b226d0d18a

• Extended scripts/add_pubmed_evidence.py with --thin-evidence N flag to also enrich hypotheses with fewer than N evidence entries (merges without overwriting existing entries).
• Enriched 13 more hypotheses with 1-2 existing evidence entries, bringing total to 20 (task target).
• Hypotheses updated: h-d4ac0303f6 (LRRK2/G2019S), h-fc43140722 (LRRK2/RAB10/microglia), h-26353f7f59 (APOE/SORL1), h-immunity-50f8d4f4 (CD8+/PRF1), h-ae63a5a13c (BRD4/BET), h-dd0fe43949 (LRRK2-Rab10-JIP4), h-aging-hippo-cortex-divergence (CDKN2A), h-immunity-c3bc272f (C1q/TREM2), h-d28c25f278 (ALDH1A1/DOPAL), h-85b51a8f58 (TREM2/TYROBP), h-c9b96e0e3b (RAB12), h-immunity-03dc171e (SPP1+ DAM), h-e8b3b9f971 (BBB/MMP).
• All 13 received 3-5 new structured PubMed entries merged with existing citations.
• Final: 120 hypotheses remain with < 3 evidence entries (no-zero-evidence non-archived hypotheses remain).

2026-04-26 02:17:00Z - Iteration 1, task:e92be9ec-2cbc-45df-87f9-23f178f8b061

• h-530326b97069 (SASP/MMP-9/TDP-43, score=0.682): 5 PMIDs (34879411, 38967083, 34930382, 33177049, 32931756) — fixed empty metadata with paper_cache.get_paper()
• h-177d9cb05108 (CHI3L1/CHIT1, score=0.5): 5 PMIDs (33328329, 35234337, 40747577, 39513754, 38866782)
• All received structured evidence ({pmid, doi, claim, source, year, url, strength, caveat}).
• h-530326b97069 had empty metadata due to NCBI rate-limit on summary API; resolved by fetching via paper_cache.get_paper().
• After: 0 active non-archived hypotheses with empty evidence_for; total with evidence = 1197.

2026-04-26 02:24:00Z - Iteration 2, task:e92be9ec-2cbc-45df-87f9-23f178f8b061

• Before: 52 active hypotheses with only 1 evidence entry (thin-evidence), 0 with truly empty evidence_for.
• DB state confirmed: SELECT COUNT(*) WHERE jsonb_array_length(evidence_for)=1 → 52; WHERE evidence_for IS NULL OR =[] → 0.
• Ran scripts/add_pubmed_evidence.py --thin-evidence 2 --limit 11 --pmids-per 5 — enriched 10/11 hypotheses (1 malformed row h-2f43b42f with title="..." had no search results).
• Enriched hypotheses (10 updated, 5 PMIDs each): h-c704dd991041 (MAPT/MAP6, tau), h-e3557d75fa56 (tau destabilizes labile pool), h-d8e13922ed22 (MAP6/CRMP2/GSK3β), h-780cbb9e6f (radiation/pericyte senescence/TFEB), h-a0b246fc70da (MAPT/MAP6 antagonism), h-5bdd4e163c5a (competition-based domain allocation), h-aging-opc-elf2 (ELF2/OPC epigenetics/Alzheimer), h-c2c5916913 (ADORA2A/parthenolide), h-1e70cd6400 (MAPT/rutin), h-ebea83c410 (ATF4-DDIT3/MAPT).

• After: thin-evidence (1 entry) dropped from 52 → 42; strong (2+ entries) = 1232; 0 empty evidence_for.

2026-04-26 02:38:00Z - Curated evidence repair task:e92be9ec-2cbc-45df-87f9-23f178f8b061

• Verified that 4 ALS hypotheses had been backfilled with partially hollow evidence bundles despite active_empty = 0.
• Added --ids targeting plus curated override support in scripts/add_pubmed_evidence.py so specific hypotheses can be rewritten when a previous generic search attached low-fit PMIDs.
• Added scripts/pubmed_evidence_overrides.json with hand-checked evidence sets for:

- h-31ca9240f9fc (TBK1): 40858618, 30146158, 25803835, 33031745

• Re-ran python3 scripts/add_pubmed_evidence.py --ids ... to replace the low-quality citations in-place.
• Verified post-write counts: active non-archived empty evidence rows = 0; archived-placeholder empty rows = 43.
• Fixed citations_count bookkeeping so replacement writes now match the actual number of evidence entries instead of preserving stale higher counts.

2026-04-26 02:43:00Z - Iteration 3, task:e92be9ec-2cbc-45df-87f9-23f178f8b061
