+Implementation:
+- Added shared `crates/project-record` helper for canonical project record IDs.
+- Ticket and Objective creation now use the same fixed-width base32 Unix epoch millisecond ID allocator.
+- IDs use alphabet `0123456789ABCDEFGHJKMNPQRSTVWXYZ` and width 13.
+- Collision handling retries by `+1ms` path probe, bounded at 1000 attempts, with no suffix/counter/random tail.
+- `created_at` / `updated_at` remain human-readable frontmatter fields; collision-adjusted ID timestamp is not silently written as `created_at`.
+- Migrated current repository records: 173 Ticket directories and 1 Objective directory.
+- Updated relation artifacts, orchestration-plan artifacts, Objective linked Tickets, docs/examples/tests, package metadata, and Nix cargo hash.
+- Added audit mapping artifact at `.yoi/tickets/00001KTNMN02R/artifacts/id-migration-map.txt`.

+Commits:
+- `4203988 feat: unify project record ids`
+- merge: `5f6c695 merge: unify project record ids`
+
+Review:
+- Reviewer approved with no request-change findings.
+- Residual note: `id-migration-map.txt` intentionally retains old ID strings as audit evidence. It is under artifacts and does not affect schema/list/doctor behavior.

+Post-merge validation:
+- `cargo test -q -p project-record`

+- `cargo test -q -p yoi objective_cli`
+- `cargo fmt --check`
+- `git diff --check`
+- `cargo run -q -p yoi -- ticket doctor`

 Result: approve, merge-ready. Residual risk: migration map intentionally retains old ID strings for audit; not a blocker.
