hermes_cli.runtime_paths (venv generations, selection, activation) moves to
pm.environments, and gains venv_bin_dir / venv_python / project_python. Every
in-tree caller asks pm for an interpreter now; pm no longer reaches back into
hermes_cli for its own environment layout (pm.packages, pm.extras, pm.ensure,
pm.paths imported hermes_cli.runtime_paths). The three open-coded
"Scripts/python.exe or bin/python" ladders in pm collapse onto venv_python.
hermes_constants.venv_python_path / venv_bin_dir and hermes_cli.runtime_paths
stay as frozen-updater-surface shims only (tests/compat/old_updater_surface.json).
To keep the boot path light, pm/__init__ resolves its facade lazily (PEP 562)
and pm.registry loads the built-in package definitions on first read instead of
at import: `import hermes_bootstrap` now loads pm + pm.environments only (25ms,
was 37ms with the eager facade dragging in the downloader). The stripped-payload
fixtures that ship only pre-import files keep working for the same reason.
Also restores two frozen-surface re-exports the F401 sweep dropped
(banner._github_compare_behind, cua_backend.resolve_cua_driver_cmd).
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.
For each issue anchor present in BASE 63279301bc non-test .py and absent on HEAD, the BASE comment/docstring block was re-attached at the HEAD location of the code it explained (matched by the distinctive code line / enclosing def). Sentences already covered by an existing HEAD comment were deduped; the issue number always survives. Insert-only: no code lines changed.
