Module provenance 

Provenance manifest — documents every choice that affected an analysis run. Per spec §3.2 provenance table + §5 differentiator.

Structs

Manifest

Constants

DUCKDB_VERSION

Pinned DuckDB version — same drift guard applies.

GIX_VERSION

Pinned gix version embedded in every provenance manifest. Surfaced both in JSON sidecars and the pre-flight banner header. Kept in sync with the gix dep in workspace Cargo.toml via tests/dep_versions_drift_test.rs, which fails CI if these constants and Cargo.lock drift apart.

MANIFEST_SCHEMA_VERSION

Explicit schema version for the provenance manifest format. Bumped whenever a field is renamed, removed, or its semantic meaning changes. Additive field changes (new optional fields with non-default Some() values) do NOT require a bump — downstream consumers using serde’s #[serde(deny_unknown_fields)] opt-in are the only ones affected by adds, and they’d need to bump regardless.
