-- State: active
-- Done: identity semantics and package boundary selected
-- Next: implement values, verifier, ADR and module specification
+- State: ready-for-review
+- Done: four identity values, boundary verifier, ADR, module specification,

+## Handoff
+
+- Commit: `c1dc07c`
+- Branch: `work/sindo-main-codex/m01-domain-identities`
+- Outcome: authored content, runtime entities, WoW wire GUIDs and namespaced
+  server entries now have separate immutable scene-free value objects
+- Contract/schema: identity contract version 1; `ContentId` uses canonical
+  lowercase UUID text. No existing schema/cache is migrated; containing future
+  schemas still require their own version and duplicate/reference policy
+- Verification: DomainIdentities PASS (`5` ContentId, `5` EntityId, `6` WowGuid,
+  `5` ServerEntryId cases); StreamingFocus, coordinate golden fixtures and
+  CoordinateMapper PASS; M00 calibration PASS with maximum error `0.000015`;
+  renderer manifest PASS (`7` checkpoints); headless project load exit `0`;
+  coordination, documentation, naming/dependency and whitespace checks passed
+- Fidelity: `WowGuid` preserves two complete unsigned 32-bit wire words and
+  explicitly does not claim build-12340 high-type semantics without packet
+  fixtures; zero GUID remains an uninterpreted observable sentinel
+- Rebuild: none; no dependency or proprietary input. Clean-worktree project
+  load reports expected missing ignored extracted assets/character resources
+- Remaining risks: no ID allocator, mapping registry or server namespace
+  vocabulary exists yet; UUID shape does not enforce generator version/variant;
+  GDScript callers must use domain `equals` or canonical keys rather than
+  reference `==`
+- Recommended merge order: after StreamingFocus at `77cd17a`, before the M01
+  manual axis-conversion rule/search gate
+- Documentation: ADR 0002, domain-identities module API/input-output/data-flow/
+  lifecycle/persistence/recovery/capability/source-map sections, module registry
+  and architecture Domain mapping added or updated
