Module sync 

Vault sync classification — a pure decision function (P9).

Given scanned markdown files and the ledger’s known note content hashes per source path, decide per file whether sync must ingest it (New), skip it (Unchanged — an episode with this exact content already exists), or ingest it as a new version (Modified — the path is known with different content).

The store fetches the KnownNotes map; this module only decides. Modified files append a new episode; the previous episode remains (append-only ledger, P1). Stale claims surface via contradictions and are removed with retract — sync itself never retracts.
