Field notes
The page frames API maintenance as a sequence of repository operations rather than an autonomous coding promise: detect a release, plan edits, verify them in a sandbox, and open a reviewable pull request. Its example follows Stripe from v14 to v18 and exposes the checks involved, including npm ci, typecheck, and test. compat also draws a clear operational boundary around the system: it says there is no auto-merge and no access to production secrets.
