Both failed only in the full Linux suite, which the targeted local
battery never ran:
- test_update_zip_two_phase.py's AST guard (#76105) flags any code
literal "Scripts" in hermes_cli as an open-coded venv layout.
migrate_windows_bin_path's legacy PATH key now derives it via
venv_bin_dir(root / "venv", windows=True) — same value, canonical
helper. The literal `venv` component stays: the key must match what
the pre-#83797 installer wrote to the registry, not where the venv
lives now.
- The managed-bin marker tests built expected PATH entries from
tmp_path, so on a POSIX host they compared forward-slash strings
against the backslash markers and could never match. Markers match
Windows registry PATH entries, so the tests now feed Windows-shaped
literals — host-independent, same contract.
Every uninstall mode deletes the code checkout, but the launchers in
the managed binary dir (%LOCALAPPDATA%\hermes\bin) live outside it and
survived -- so `hermes` in a new terminal resolved to a launcher whose
venv target was gone and errored, which reads worse than
command-not-found.
remove_windows_bin_launchers deletes both launcher forms (.exe/.cmd)
from the managed binary dir in every uninstall mode, anchored on the
default Hermes root so profile sessions cannot redirect the sweep into
profiles\<name>\bin. When the uninstall itself runs through the
launcher, that exe is mandatory-locked against deletion but not rename
(the same fact _quarantine_running_hermes_exe relies on), so it falls
back to renaming the launcher aside.
The managed uv (uv*.exe) in the same dir survives, and the hermes\bin
PATH entry is swept only on a full wipe from the default root
(include_managed_bin) -- a keep-data uninstall keeps the still-working
uv resolvable for reinstalls.
A lockstep test parses install.ps1's staging loop so the swept names
cannot drift from the staged names silently.
