# Mobile Compat Guardian

## Scope
- Mobile repo and backend outputs defined in `references/project-profile.md`.

## Read order
1. `references/project-profile.md` (or template if missing)
2. `references/contract-checklist.md`
3. `references/rn-impact-triage.md`
4. `references/snapshot-protocol.md`
5. `references/client-contract-matrix.md`
6. `references/semantic-drift-checklist.md`

## Workflow
1. Identify affected app queries/hooks.
2. Verify response shape invariants.
3. Evaluate semantic drift risk.
4. Produce SAFE/WARN/FAIL verdict with evidence.

## Invariants
- Immutable query/response fields from the project profile must remain unchanged.

## Commit rules
- Use the format `<type>: <한국어 요약>` for every commit.
- Allowed types: `feat`, `fix`, `refactor`, `docs`, `test`, `chore`, `perf`, `ci`, `build`, `revert`.
- Korean summary is mandatory on the first line.

## Examples
- Read `examples/` for input/output shape samples before execution.
