+Numbering gaps in Check IDs are **intentional**. Do not fill gaps by reusing retired IDs.

+## Policy
+
+- After a **tagged release**, never delete a published Check ID. Deprecate with `status: deprecated`, `replacedBy`, and `deprecationNote` (N−1 MINOR support window). See `CONTRIBUTING.md` and `ARCHITECTURE.md`.
+- **Mandatory → recommended** always needs an RFC (`ARCHITECTURE.md`).

+
+APRF `0.10.x` is a working draft; **no release versions have been tagged yet**. For this window only, stewards may remove a Check ID when remapping M→R **if** an RFC records the remapping and this file lists the gap.
