Deprecation Register
The source of truth is deprecation-register.yaml.
Use this register for compatibility shims and legacy paths that must be removed later.
Required fields
id: stable identifier (do not rename once published).scope: affected surface area (for exampleglobal-config,api-config,frontend).summary: what compatibility behavior exists and why.introduced: date the compatibility path was introduced (YYYY-MM-DD).remove_by: date this must be removed or explicitly extended (YYYY-MM-DD).owner: responsible team or owner handle.tracking_issue: issue/doc path for cleanup work.status:activeorcompleted.evidence: files proving where the compatibility behavior exists.
Enforcement
Validation runs in:
make deprecations.github/workflows/lint.yml(deprecation-registerjob)
The validator fails CI when:
- required metadata is missing or invalid, or
- an
activeentry passes itsremove_bydate.
When cleanup is intentionally deferred, update remove_by and link a tracking issue in the same PR.
