The Tactician’s Web of Large-Scale Formal Knowledge

tactician’s web: coq proofs as ml data and live agent platform
- exports text and semantic graph, records tactic proof states, lets agents run tactics via coq kernel terms as labeled directed graphs
- equal terms iff graphs bisimilar, no alpha-conversion needed
- universe collapse is inconsistent as type theory
- omits typeclass and hint-database behavior context meta-graph preserves imports, sections, module instantiation
- derived definitions via sections cause train/test leakage
- roughly half of 520k released definitions
- random splits discouraged, split by dependency hash-sharing of bisimilar subgraphs
- stdlib nodes 157M to 18.3M (88.3% fewer) tactic proofs as state transitions
- 4.6M transitions recorded, 76 broke the unshelved-state assumption
- tactics decomposed and anonymized benchmark framework
- opam environments, scales to 120k lemmas on 1000+ cpus take for verus
- context-keyed retrieval, dependency-aware splits, record verifier-clean proofs with denominators
