📝 WalkthroughWalkthroughThe compatibility scripts now validate JAR inputs, support configured TASTy package exclusions, and use distinct exit codes for incompatibilities and check failures. The workflow classifies binary and TASTy results separately, reports the implied version bump, and updates pull request labels and comments. ChangesCompatibility checks and PR reporting

Merge Risk: 🟡 Moderate · up to Pull requests from forks and from Dependabot can now fail the compatibility check even when nothing is incompatible. Separately, a participant's comment that starts with the report marker can redirect the report update to their comment. Both fixes are small and should be made before merging. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Keep read-only PR runs from failing during label creation.
For a fork PR or Dependabot PR, GitHub normally gives this pull_request run a read-only token. Both gh label create commands run even when the compatibility checks pass. The first write failure stops the step and makes the check fail. Skip PR mutations when the token is read-only, or perform them in a separate privileged workflow that does not execute PR code.

Match the sticky comment’s author as well as its marker.
Any PR participant can post a comment that starts with <!-- mima-report -->. If that comment is the last match, the workflow selects its ID for the update instead of the workflow’s comment. The update can then fail or replace a participant’s comment. Filter the API results by the workflow comment’s author before selecting an ID; issue-comment results include author information.
