Editing the body of an already-released installer migration drifts its computed checksum (it hashes plan.toString()). The integrity guard then hard-aborted every prior install on upgrade with "applied migration checksum changed" — a 100% reproducible blocker (v1.3.0, all platforms). Already-applied migrations are filtered out of `pending` and never re-run, so a drifted checksum is functionally inert. ADR-0008 anticipates checksum-mismatch state as something the install-state layer must handle gracefully (plan -> apply -> recover/report), not abort on. This supersedes the published-checksum allowlist merged in #674 (per-release maintenance debt — every historical checksum hand-pinned, still throws for any unregistered value) with a general, self-healing recovery: - Replace the throwing guard with non-fatal `collectAppliedChecksumDrift`, surfaced on `plan.checksumDrift`. - Reconcile drifted stored checksums durably on the next state write (`reconcileDriftedChecksums`), idempotently (no perpetual writes). - Relocate the "shipped migration bodies are immutable" rule to a CI baseline test that locks every shipped migration's checksum and fails on body drift — where #615 should have been caught, instead of blocking users. Removes #674's legacyChecksums field, per-migration checksum pins, published-checksums.json fixture, and compat test. Fixes #670 Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com>

npx @opengsd/gsd-core upgrades no longer abort with "applied migration checksum changed" — an already-applied installer migration whose recorded checksum drifted (e.g. a shipped body was edited) is now detected and reconciled automatically on the next install, instead of hard-failing the upgrade. Replaces the published-checksum allowlist with general self-healing recovery plus a CI baseline lock.
