- Around line 31-33: Update the documentation statement around the managed-venv
coverage to match test_path_contract.py: either narrow the claim to removing
mnemosyne-side-venv and detecting stale_wrapper, or add coverage that recreates
the managed venv and executes the wrapper afterward.

Align the managed-venv replacement claim with the test coverage.
integrations/hermes/tests/test_path_contract.py removes mnemosyne-side-venv and checks for stale_wrapper. It does not recreate the managed venv or exercise the wrapper after replacement. Narrow “simulated managed-venv replacement” in the documentation, or add a smoke test for recreation and wrapper execution.

Summary
Why this owner/path
The contract belongs at the Mnemosyne Hermes integration boundary because these are the paths and runtime assumptions our wrapper actually owns. The tests are derived from the existing installer helpers and exercise the public wrapper install path. They do not attempt to run or simulate the Hermes installer.
What this does not claim
This PR does not verify or implement:
hermes uninstall, provider removal, or profile deletion semantics;Those remain upstream Hermes gates tracked from issue #859.

This is the right boundary. Centralized, code-derived path data improves long-term maintainability. The tests avoid claiming to verify Hermes behavior that this repository cannot observe.
The PR does not verify Hermes Desktop updates or uninstall behavior, shared-venv conflict handling, or experimental package-manager compatibility.
