Fold the helper into _npm_lifecycle_env itself: the whole fix is one
is_file() check plus a setdefault, so a separate function, the
try/except around get_hermes_home() (it never raises) and the
dict-returning indirection were shape-gate violations. Build the path
with os.fspath so it is correct on Windows too.
Tests: keep the two invariants (file present -> NPM_CONFIG_USERCONFIG
points at it; explicit process/caller value wins and a missing file
sets nothing), fold the other two into the negative test.
Docs: one paragraph in the desktop troubleshooting page next to
ELECTRON_MIRROR describing $HERMES_HOME/npmrc.
Refs #106373
Fence owner discovery by profile, lease and loopback endpoint, and hand the authenticated URL to the existing Ink transport without acquiring a competing lease. Distinguish lease age from turn activity in unsupported-owner recovery.
Client slice only: requires the integration runtime to advertise shared_runtime_url and provide the session-attach handshake. Classic CLI attachment remains an integration gap.
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.
