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).
Competing installers and checkout-local venv assumptions bypassed PM
selection, install consent, and generation lifetimes. Route consumers
through PM and installation-bound launchers. Refresh source launchers
before obsolete Python entries can be collected.
Remove Node, browser, and CUA acquisition engines, obsolete venv-holder
handling, detached sync, and unused PM APIs. Keep historical updater
exports inert and preserve external tool ownership and native integration.
Share product freshness and prepared inputs across builders. Align plugin
admission, Docker provisioning, setup instructions, and behavioral tests.
Verified targeted Python and JavaScript tests, desktop and web typechecks,
scoped lint, real product builds, and the Docker frontend smoke test.
The missed post-setup test cleanup is included and verified.
Native Windows/macOS execution, full Rust compilation, and the complete
repository suite remain unverified. Historical compatibility requirements
were preserved and extended, not fully rescanned.
