Summary

Two unrelated CI bugs, both visible since PHP 8.5 was added in #92 on 2026-04-28. Bundled together because they're both small workflow / Dockerfile fixes.

1. Nightly PHP 8.5 base image build broken (13 days running)

Symptom: build-base-images.yml schedule run fails every night since 2026-04-28. All four PHP 8.5 jobs fail at the "Build and push" step on both amd64 and arm64. PHP 8.3 and 8.4 are unaffected.

Root cause: docker-php-ext-install -j$(nproc) hits a race condition in PHP 8.5's revised build system — the install-modules make target runs cp modules/* before the parallel compile finishes:

#9 77.80 cp: cannot stat 'modules/*': No such file or directory
#9 77.80 make: *** [Makefile:89: install-modules] Error 1
#9 77.80 make: *** Waiting for unfinished jobs....
ERROR: failed to solve: process "docker-php-ext-install -j$(nproc) ..." did not complete successfully: exit code: 2

Fix: Drop to -j1 on Dockerfile.8.5 and Dockerfile.8.5-node. Slower nightly compile, but a nightly build trading speed for reliability is the right call.

2. Dependabot automerge workflow spuriously failing

Symptom: 3 automerge workflow runs failed today alone with the misleading error:

##[warning]Event payload missing `pull_request` key.
##[error]PR is not from Dependabot, nothing to do.

Root cause: The workflow had workflow_run configured to fire whenever Tests or Lint completed — including on main after a PR merges. In that context github.event.pull_request is null, but github.actor is still dependabot[bot] (because the merged PR was from dependabot), so the job runs and dependabot/fetch-metadata@v3 bails with the error above.

Fix: Drop the workflow_run trigger entirely. It was a belt-and-suspenders backup, but the existing fountainhead/action-wait-for-check polling inside the job already handles the "wait for Tests/Lint to complete" case it was trying to backstop. If a real timeout case ever shows up, we can add it back with proper PR-context extraction (github.event.workflow_run.pull_requests).

Closes

• Closes #94 (auto-filed nightly build failure)

Test plan

• CI on this PR runs clean (Tests / Lint / Pint / PHPStan)
• After merge, manually trigger build-base-images.yml and confirm all 8.5 variants build successfully
• Watch the next nightly run lands green
• Confirm no spurious automerge failures on main after the next dependabot merge
