cached_sdk_client returned the client cached on tools.web_tools before it
read the key, so the Exa, Parallel and AsyncParallel clients kept the key
they were first built with for the life of the process. A key fixed in .env
and applied with /reload still sent the old key (401s until a restart), and
on a gateway serving multiplexed profiles every profile's Exa and Parallel
calls went out on whichever profile's key built the client first, billed to
that account. A key removed from the environment also kept being used.
Resolve the key on every call and reuse the cached client only when it was
built with that key; the slot now holds (key, client) as one value so two
builds racing under different keys cannot record one key beside the other
key's client. Firecrawl already compares its credential before reusing its
client; this brings the two SDK-backed providers in line.
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.
