* fix(ci): clear the pinned corepack cache before every install The Linux test shards have been dying seconds into Install dependencies with MODULE_NOT_FOUND on the cached pnpm's bin/pnpm.mjs since #16328 pinned COREPACK_HOME to runner.temp (main runs 41876940141, 41889761157, 41927887452; six different self-hosted hosts). The pin assumed runner.temp is per-run, but self-hosted runners keep _work/_temp across jobs — the lint job's isolated-HOME step already documents this. corepack trusts an existing cache entry without re-verifying its files, so a partial pnpm tree left by an earlier job fails every later job on that host. Clear the pinned cache at the start of the shared install body in all three jobs that copy it, enforcing the per-run contract the pin documents. The guard keeps the reset a no-op where COREPACK_HOME is unset (test_build) or already run-unique (lint). The test step still reuses the cache install warms in the same job, and poisoned hosts self-heal on their next job without manual cleanup. Pin the reset and the install/test COREPACK_HOME match in the workflow meta-test, and bump the size baseline for the added lines. * fix(ci): scope the corepack cache reset to the shard-owned path Review found two over-deletion shapes in the nonempty guard: a runner that exports COREPACK_HOME would lose its entire shared cache in the build job, and hosted lint would lose the cache its pnpm-store step had just warmed, re-exposing the install to a registry outage. Match only the exact shard-owned path instead; the build and lint copies become unconditional no-ops and the three install bodies stay byte-identical. Add an execution test that runs the shipped guard fragment under a scrubbed environment across five cache shapes: it kills the dead-guard mutant the string pins survived, and a widened-guard mutant dies on the shared-cache survival cell. State the incident as observations with the corruption source undetermined, and correct the stale per-run rationale beside the pin.
