CoRE-DB value-filling agents

Backup of the multi-agent per-database value-filling artefacts from campaigns/chained_05b_tkde/valuefill_agents/ in thanhdath/finer-sql-tkde (private repo). This is the offline-proxy measurement harness and its outputs backing the paper's agentic value-filling section, not a training corpus by itself.

What this answers

The CoRE-DB construction fills each compact database with random instances to separate a gold SQL query from its near-miss neighbours (edits that would otherwise collect reward spuriously). One shared random-value generator (v18/fuzz_lane/generate.py) fills every database today. This package asks whether a per-database value-filling program — written by a Coder agent and accepted only after a Verifier agent proves it by execution — separates more (gold, near-miss) pairs than the shared generator, on the same pairs, same instance budget, and never separates fewer.

Run of record

2026-09-15 .. 2026-09-17, model claude-sonnet-5. Full sweep over both corpora's eligible train databases:

corpus	eligible	swept	verified module	unverified
BIRD train	72	52	42	10
Spider train	167	116	106	10
total	239	168	148	20

An unverified database has no fill_rules.py; it falls back to the shared generator. Its meta.json, verifier_report.json and attempts/ are kept — the repair rounds that failed are as much the audit trail as the ones that succeeded.

Full-sweep headline (held-out pairs, offline-proxy label)

Held-out = pairs not used to construct/verify the evaluated database's module (the construction-ceiling numbers, run on the in-sample pairs, are in the same eval files).

corpus	pairs	shared catch	agent catch	delta
BIRD (out/full_bird/eval_heldout.json)	1,607	29.68 %	31.86 %	+2.18 pp
Spider (out/full_spider/eval_heldout.json)	1,350	43.63 %	44.89 %	+1.26 pp

The 10-database BIRD pilot (out/eval_heldout.json) reported a larger delta (+2.77 pp) at smaller N; both are offline-proxy, not end-to-end EX numbers.

out/full_bird/ and out/full_spider/ are the multi-MB dumps the source git repo deliberately does not commit (>1 MB rule in the package's own MANIFEST.md); this dataset is their durable copy. Everything under bird-train/, spider-train/, out/sample.json, out/pairs*.json, out/eval*.json and out/verification/ is also committed in the source repo — mirrored here for a single place to pull the whole artefact set from.

Not included, by the source package's own contract (see its MANIFEST.md): generated .sqlite instances, verifier trial databases, and anything under /dev/shm — all transient and regenerable from fill_rules.py + the base databases.

Provenance / labels

• Label on every eval file: offline-proxy — a proxy measurement (does the arm separate more near-miss pairs), not an end-to-end trained-model EX comparison.
• No query in fill_rules.py construction is informed by RL rollouts; it operates on gold SQL and schema only.
• Reproduce: campaigns/chained_05b_tkde/valuefill_agents/scripts/run_all.sh (source repo); the second and later runs are free — every LLM call is cached by sha256(system + user + model + flags) under runs/<key>/.
