# Data schema

`data/candidates.jsonl` is the main table. Each row contains:

- construction: `ell`, `m`, twisted geometry, `A_terms`, `B_terms`;
- independently recomputed `n`, `k`, ranks, CSS commutation, weights and degrees;
- strict target distance and status;
- rigorous distance/FOM lower, upper, and exact fields kept separate;
- advisory BP/OSD fields kept separate from proof evidence;
- novelty replay summary and matrix file/hash bindings.

`evidence/proofs.jsonl` contains the matching proof summaries. `formal_lower_bound_evidence` stores the two-sector low-weight exclusion record; `logical_basis_upper_bound_evidence` stores a replayable logical witness; `trusted_audit` stores a sanitized view of the sealed audit artifact. Local paths, interpreter paths, PIDs, commands, prompts, and logs are not exported.

`evidence/matrix_index.jsonl` indexes Matrix Market files. All matrices are binary even though Matrix Market labels entries as integers. Coordinates are one-based.
