# Versioned sync fixtures

These JSON files are server contract fixtures. They intentionally model client
payloads as opaque snapshots: server sync tests must push them, pull them back
and compare the payloads strictly without teaching the server the client schema.

Structure:

- `exercises/v1/`: first captured exercise fixture batch.
- `exercises/v2/`: second captured exercise fixture batch used to prove tests
  can run multiple fixture generations side by side.
- `programs/v1/`, `workout_templates/v1/`, `workout_histories/v1/`: reusable
  minimal sync batches for non-exercise resources.

Folder names such as `v1` and `v2` identify fixture batches, not the payload
schema itself. The authoritative client schema value remains the JSON
`schemaVersion` field inside each fixture, and tests assert that the server
preserves that value exactly.

When the client schema changes, add a new fixture batch folder instead of
rewriting older fixtures. Old fixture versions are kept to verify backward and
forward compatibility.
