Pull request overview
This PR adds an automated regression guard to detect unintended changes in component fingerprint computation, helping keep fingerprint.ComputeIdentity stable across config/schema evolution.
Changes:
- Adds a per-field snapshot table test that enumerates all fingerprinted leaf fields in
projectconfig.ComponentConfigand records each field’s isolated fingerprint. - Adds a fuzz test that exhaustively populates fingerprinted fields and checks determinism and sensitivity across seeds.
- Checks in the initial go-snaps snapshot for the per-field table.
