check-codesign
Check macOS code signature, hardened runtime, entitlements, and notarization of audio plugin bundles (.vst3, .component, .clap, .app/.appex). Use when user says "check code signing", "check codesign", "check signature", "verify signing", "check notarization", "why won't plugin load", "hardened runtime", "check entitlements", or a plugin fails to load in a signed DAW.

# macOS Code Signature Check
## Why This Matters
macOS DAWs built with hardened runtime (Logic Pro, GarageBand, recent versions of Ableton Live, etc.) will refuse to load unsigned or incorrectly signed plugins. Gatekeeper and library validation enforcement mean that even a plugin passing all functional tests can silently fail to load if its code signature is missing, invalid, or lacks required entitlements.
## Plugin Bundle Locations
| Format | Extension | Typical Paths |
|--------|-----------|---------------|
| AudioUnit v2 | `.component` | `~/Library/Audio/Plug-Ins/Components/`, `/Library/Audio/Plug-Ins/Components/` |
| AudioUnit v3 | `.appex` (inside `.app`) | Built into host app bundle |
| VST3 | `.vst3` | `~/Library/Audio/Plug-Ins/VST3/`, `/Library/Audio/Plug-Ins/VST3/` |
| CLAP | `.clap` | `~/Library/Audio/Plug-Ins/CLAP/`, `/Library/Audio/Plug-Ins/CLAP/` |
