# Snapshot format 0.1

Normative files:

- `contracts/snapshot.schema.json` — entity, relation, source, and claim document.
- `contracts/manifest.schema.json` — presentation. Kind names, facet names, and relation wording live here.
- `contracts/MIGRATIONS.md` — version gate.
- `contracts/fact-policy.md` — missing, unknown, and contradiction.

Identifiers for entities are `urn:ce:<dataspace>:<kind>:<key>`. The same key in another dataspace is a different entity. Relation ids are local to the snapshot.

A published example must contain at least three kinds and eight entities. `scripts/validate_fixtures.py` enforces that, plus the schema, dangling references, duplicate ids, missing sources, and cycles on `acyclicPredicates` only.
Freeze the v0.1 contract and the local ingest connector. The snapshot and manifest schemas, both example dataspaces, and the shared text renderer now pass the fixture validator and the negative contract tests. JSON, NDJSON, and Markdown frontmatter publish a snapshot only when rights, identity, and references allow it. CONTENT-WP-0001 and CONTENT-WP-0003 are marked finished against those artifacts. CONTENT-WP-0000-T04 stays open. SCOPE.md and the 19:05 scope-against-intent note record the stop.
