fix(ci): make Self Auto-Merge actually start (grant write scopes; local path)#4

Conversation
The Self Auto-Merge dogfooding workflow startup-failed on every PR since it was added (3/3 runs) because it referenced its own reusable via the full owner/repo path pinned @main. A same-repo reusable referenced that way startup-fails on pull_request; the local ./ path resolves to the caller's own commit (no self-lag) and is GitHub's documented same-repo pattern. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The actual cause of the startup_failure: the repo default workflow token is read-only, this caller declared no permissions, and the reusable auto-merge job requests contents: write / pull-requests: write — so GitHub rejected the run at startup. Grant those scopes on the caller. (The prior local-path change was a valid cleanup but not the fix.) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Summary
The Self Auto-Merge dogfooding workflow has
startup_failureon every run since it was added in v1.3.1 (never once succeeded).Actual root cause: the repo's default workflow token is read-only,
self-auto-merge.ymldeclared nopermissions:, and the reusableauto-mergejob requestscontents: write+pull-requests: write. GitHub rejects the run at startup ("requesting contents: write... but only allowed contents: read"). Fixed by granting those scopes on the caller.Also (secondary cleanup, not the cause): switched the reusable call from the full
…@mainpath to the local./path — idiomatic for same-repo reusables and resolves to the caller's own commit.Self-verifying
actionlint(required check onmain) must pass.dependabot[bot]) instead ofstartup_failure. That transition is the proof.Related config (already applied)
main: requireactionlint, admins exempt, no required reviews (requiring reviews would block dependabot's own auto-merge).Security invariants preserved
on: pull_request(notpull_request_target) — fork PRs get a read-only token and no secrets even with the newpermissions:block.if: github.actor == 'dependabot[bot]'gates the merge steps.🤖 Generated with Claude Code
