v1.2.1 — Verified Premiere mutations
Premiere mutation verification
- Fixes audio level writes by converting dB to Premiere amplitude values and verifying readback.
- Uses Premiere
Timeobjects for audio keyframes and verifies every keyframe write. - Verifies ripple-delete, razor, and transition postconditions so affected Premiere Pro 26.3 hosts no longer report false success.
- Returns clear compatibility errors and documents structural-edit and transition workarounds.
Platform and performance improvements
- Adds machine-readable Windows/macOS capability reporting and fail-closed authority enforcement across all tools.
- Adds Windows/macOS CI coverage on Node 18 and 22.
- Improves macOS CEP installation and diagnostics.
- Reduces bridge polling and caches immutable server construction metadata.
Validation: 346 automated tests, TypeScript build, npm package dry-run, and all four Windows/macOS CI jobs passed.
