"""Shared pydantic models for the TidalCycles → tracks tooling (L'Armada).

One typed, JSON-serializable vocabulary across the fleet: provenance, the
locate-matrix cell, the master edit-decision list (EDL), and the sample TF-IDF
report. Every produced artifact is a model → validated on read, dumped on write.

Design rules encoded here:
  - **Metadata carries provenance** (value + source TYPE + locator + as_of), so any
    fact is traceable and corrections propagate. (feedback_metadata_provenance)
  - **The ear is the oracle**: a match isn't `verified` until source=user/ear.
  - **Never invent gig metadata**: gig is a site slug (a pointer), not a fact.

JSON: `m.model_dump_json(indent=1)` to write, `Model.model_validate_json(txt)` to
read. Enums serialize as their string value.
