Prepare dependency generations before selecting them. Keep shipped tool
bytes separate from writable additions, and store facts beside their entries.
Validate proposed plugin sets before config publication. Restore the previous
config if the facts write fails.
Consolidate duplicate updater, backup, setup, and voice helpers. Repair
launcher selection, dependency consumers, download ownership, update feeds,
and native Windows process and file handling.
Verification: 206 changed/prior-failing Python files reported 4630 passed,
one failed, and 330 skipped. Fix the remaining Hindsight fixture boundary.
The final targeted rerun reported 234 passed and two skipped. The store
review regression batch reported 83 passed and one skipped. Desktop
TypeScript checks, 56 selected Electron tests, 24 release tests, and the
removed-import/compatibility guards passed.
This is an integration checkpoint, not full audit acceptance. The complete
Python suite has not run on this fixed tree. Crash-atomic plugin publication,
generation cleanup, receipt correlation, and packaged lifecycle acceptance
remain open in docs/pm-audit-status.md.
- provider_registry.py: ProviderRegistry (global + per-scope maps, lock,
generation counters, register/list/get/snapshot/restore/reset) with
export() binding the historical module-level names and _providers/
_scoped_providers/_lock test hooks into each *_registry module
- is_available_safe / configured_provider_name replace the 4 nested
_is_available_safe closures and 2 config-reading blocks
- browser/image_gen/video_gen/web_search/terminal_env/tts/transcription
registries keep their public API, log strings, error strings, builtin
collision policy (warn vs raise) and key normalization (strip vs lower)
