[Gaps] Automated gap dependency mapping from KG + hypothesis graph open analysis:5 reasoning:6 safety:9

Goal

Scan knowledge_edges and hypotheses to automatically infer gap_dependencies.
If two gaps share target entities, hypotheses, or pathways, create 'informs' links.
If one gap's resolution criteria include another gap's title, create 'requires' link.
Use LLM for relationship classification on ambiguous pairs.

Acceptance Criteria

Approach

Load all gaps with titles + resolution_criteria

For each gap, collect entity set: target_gene + target_pathway from linked hypotheses

Pairwise compare gaps: count shared entities → strong overlap (≥2) → 'informs'

Check resolution_criteria text for references to other gap titles/keywords → 'requires'

LLM: for borderline pairs (1 shared entity), classify relationship and strength

Insert new rows into gap_dependencies with INSERT OR IGNORE

Dependencies

• knowledge_gaps table
• hypotheses + analyses tables (to get entity sets per gap)
• gap_dependencies table (already exists)

Work Log

2026-04-06 — Slot unassigned

• Created spec
• Implemented gap_dependency_mapper.py
• First run: inserted 27 dependencies (7 heuristic strong-pairs + 20 LLM-classified borderline pairs)

2026-04-06 — Recurring run (task:99990586)

• Ran mapper: 108 gaps loaded, 17 with entity data, 27 existing deps
• 7 strong pairs all already covered (skipped_existing), 0 new informs links
• 0 resolution-criteria pairs found (no gap title cross-references in RC text)
• LLM: 27 borderline pairs all already had existing relationships, 0 LLM calls
• Result: idempotent; no new rows inserted (database up to date)

2026-04-09 20:18 PDT — Slot manual validation

• Added --db CLI flag to gap_dependency_mapper.py so the script matches this spec and recurring invocation patterns
• Re-ran the mapper end-to-end after queue cleanup: loaded 123 gaps, inserted 53 new dependency rows, skipped 7 existing rows, made 16 LLM calls, added 14 new LLM-classified relationships
• Validated the new CLI surface with timeout 120 python3 gap_dependency_mapper.py --db postgresql://scidex --no-llm
• Result: idempotent on the current DB state (0 new rows, 42 existing strong-pair links skipped)
• Result: ✅ Healthy recurring mapper with spec-aligned CLI surface

2026-04-10 10:07 PDT — Slot running

• Ran full mapper with LLM: 308 gaps loaded, 30 with entity data, 80 existing deps
• 42 strong pairs (all existing, skipped), 82 borderline pairs (LLM-capped at 20)
• 2 LLM calls made (all borderline pairs already had relationships), 0 new deps
• Result: ✅ Database up to date, idempotent

2026-04-10 10:38 PDT — Slot verification run

• Ran mapper with --no-llm flag: 308 gaps loaded, 30 with entity data, 80 existing deps
• 42 strong pairs (all existing, skipped), 0 new deps inserted
• Verified idempotent operation: 0 inserted, 42 skipped_existing
• Result: ✅ Database confirmed up to date

• Result: ✅ Database confirmed up to date

2026-04-10 11:29 PDT — Verification run

• Database confirmed fully up to date
• Result: ✅ Task complete — recurring mapper healthy and idempotent

2026-04-11 04:36 PDT — Slot running

• Ran full mapper with LLM: 2592 gaps loaded, 30 with entity data, 80 existing deps
• 42 strong pairs (all existing, skipped), 82 borderline pairs (LLM-capped at 20)
• 2 LLM calls made (borderline pairs already had relationships), 0 new deps

Scalability fix: KG hub-gene explosion at 3324 gaps

• Gap corpus grew from 674 → 3324; previous run produced 1M+ spurious strong pairs

(hub genes like APOE expand to 200+ KG neighbors shared across all neuro gaps)

• Fixed find_shared_entity_pairs(): snapshot pre-expansion entity sets, require ≥1

original shared entity before crediting KG-expanded overlap (original_entities param)

• Added max_pairs=2000 cap with descending-overlap sort so highest-signal pairs

win when corpus is large; borderline cap = max_pairs // 2 = 1000

• Added progress logging every 500 inserts (BATCH_SIZE)
• Result: 3324 gaps, 2451 with entities, 109K candidate pairs → 2000 strong + 1000

borderline after cap; 1591 new informs links inserted; full re-run idempotent
(0 new, 2000 skipped); LLM calls degraded gracefully (MiniMax returned empty, handled)

• Result: ✅ Scalability fixed; 11138 total gap dependencies now in DB

2026-04-12 — task:99990586-2e01-4743-8f99-c15d30601584

KG entity augmentation + llm.py migration

• Added load_gap_title_entities(): extracts uppercase gene symbols from gap title+description

via regex [A-Z][A-Z0-9]{1,9} with a blocklist of non-gene acronyms (PMID, RNA, DNA, etc.)

• Added load_kg_neighbours(): expands each gap's gene set via one-hop knowledge_edges traversal

(gene↔gene and gene↔protein edges only, max 50 entities per gap)

• Added _NON_GENE_TERMS blocklist to prevent common biology abbreviations polluting entity sets
• Updated run() to merge hypothesis-linked (A) + title-derived (B) + KG-expanded (C) entity sources

before pairwise comparison

• Added --no-kg CLI flag to skip KG expansion
• Replaced anthropic.AnthropicBedrock in llm_classify_gap_pair() with from llm import complete

to use the site-wide provider chain (minimax → glm → claude_cli)

• Result: 3259 gaps loaded, 2398 with entity data (was 34), inserted 1,848 new gap_dependencies

(total: 1,928 vs 80 before this run)

2026-04-27 21:35 PDT — task:99990586-2e01-4743-8f99-c15d30601584

PostgreSQL rewrite + idempotency fixes (commit 7d7ffdc71)

• Task branch was branched from pre-SQLite-retirement codebase; this run brings

gap_dependency_mapper.py in line with the PG-only SciDEX datastore

• Fixed knowledge_edges schema: source_id/target_id (not subject/object),

source_type/target_type (not rel_type) — gene/protein edges via source_type IN ('gene','protein')

• Fixed id sequence desync causing "duplicate key violates gap_dependencies_pkey":

added setval() before each batch to keep PG serial in sync with actual max id

• Changed insert to INSERT ... ON CONFLICT DO NOTHING RETURNING id for accurate counts
• Fixed find_borderline_pairs() slice bug: gap_ids[i+1] → gap_ids[i+1:] (was indexing

single char from string instead of slicing list)

• Current DB: 14,267 gap_dependencies (14,001 informs + 292 requires + 3 subsumes)

across 3,529 knowledge gaps

• Re-run confirmed idempotent: 0 new deps, 2000 strong pairs skipped_existing
• Full LLM run: 20 calls → 20 new deps (capped at max_llm=20)
• Result: ✅ PG-rewrite complete; idempotent; mapper healthy
