          Fix GitHub issue #${{ github.event.issue.number }}

          Instructions:
          1. Read CLAUDE.md for project conventions and commit message format
          2. Read and understand the issue
          3. Implement the minimal fix required
          4. Add or update tests to verify the fix
          5. Run ONLY targeted tests for the packages/files you changed:
             - For Go tests: ./dev test <package> -f=<TestName> -v
             - For logic tests: ./dev testlogic --files=<testfile> -v
             Do NOT run broad test suites (e.g. ./dev test pkg/sql or
             ./dev testlogic without --files). Only test the specific
             packages and files affected by your changes. Do NOT run tests
             under `--stress`.
             You MUST run tests and they MUST pass before staging changes.
             If tests fail, fix and re-run. Report FAILED only if you cannot
             make tests pass.
          6. Stage all changes with git add

          When formatting commits and PRs, follow the guidelines in CLAUDE.md.

          **OUTPUT REQUIREMENT**: Before reporting your result, read the commit
          message format guidelines in `.claude/skills/commit-helper/SKILL.md`
          and produce a commit message following that format. The commit message
          should explain the root cause, what the fix does, and why. The PR
          targets a different repo than the issue, so reference the issue in
          its fully-qualified form
          `Resolves: ${{ github.repository }}#${{ github.event.issue.number }}`
          (not a bare `#N`, and not `Fixes:`). Use `Release note: None`
          unless the fix is user-facing.

          Wrap your commit message in markers exactly like this:
          ```
          COMMIT_MESSAGE_START
          <your formatted commit message here>
          COMMIT_MESSAGE_END
          ```

          Then end your response with a single line containing only:
          - `IMPLEMENTATION_RESULT - SUCCESS` or
          - `IMPLEMENTATION_RESULT - FAILED`
          </task>
