Canon optimistic locking for ERP documents: version + expectedVersion, 409 CONFLICT_VERSION — docs/recipe only, not a package. Distinct from epoch.

Optimistic document version

Read knowledge/optimistic-document-version.md only.

Quick rules

  • Aggregates carry version; PATCH sends expectedVersion.
  • Mismatch → 409 CONFLICT_VERSION (versionConflict() / BackseatVersionConflictError from @eristack/backseat).
  • SQL: UPDATE … WHERE id = ? AND version = ?.
  • Epoch bumps cache — not write conflicts.

No @eristack/concurrency package unless maintainers add one later.
