X_SOURCE_BARE_ERROR_EXEMPT_STALE
Means
an exemption in the bare-Error inventory names a site that holds no bare throw
Typical cause
the throw it allowed was repaired, or the file was renamed or deleted — and an exemption nobody reads is a licence the next throw inherits. The inventory is per SITE, so one row can never excuse a replacement thrown elsewhere
Fix
bun run scripts/test-bare-error.ts --json, then delete the stale row from scripts/lib/source-bare-error-exemptions.ts
