Replaces dawidd6/action-send-mail with hyperpolymath/smtp-notify-action v0.1.0 (tag commit 1b3b752d39a4fe4c0f28f10905e4608789d3e050), per the 2026-09-02 ruling (standards spec §5.5/§9, PR hyperpolymath/standards#725). The whole file is the rsr-template-repo canonical, so besides the uses: line it also: limits the trigger to branch pushes (tag/deletion payloads mislabel Branch:), drops actions: read (unused), and adds timeout-minutes: 5. Dormant gating on vars.PUSH_EMAIL_ENABLED == 'true' is unchanged. Line 1 SPDX header kept as it was.

Engine: .git-private-farm/scripts/smtp-notify-sweep.sh. Verification for this repo: regime=lock pristine=valid post=valid changed=.github/workflows/actions.lock,.github/workflows/push-email-notify.yml, sig=G 3b23e41 base=main
(pristine/post = gh actions-lock --no-fix validity before/after; repair = the lock was already invalid before this change and is valid after it.)

Review Change Stack

📝 Summary

Summary by CodeRabbit

  • New Features

    • Restored email notifications for branch push events.
    • Notifications remain disabled unless explicitly enabled through the relevant setting.
    • Updated the notification delivery service to improve compatibility with SMTP-based email delivery.
  • Reliability

    • Added a five-minute execution limit to help prevent stalled notification jobs.
    • Limited notifications to branch pushes, avoiding messages for other push event types.

Walkthrough

The push-email workflow now runs for branch pushes only, stops after five minutes, and uses hyperpolymath/smtp-notify-action@v0.1.0. Comments document the dormant switch, SMTP settings, template inheritance, and action pinning.

Changes

Push email workflow

Layer / File(s) Summary
Workflow trigger, execution limit, and email action
.github/workflows/push-email-notify.yml
The workflow now targets branch pushes, adds a five-minute job timeout, and replaces the email action. Comments document the disabled-by-default switch, SMTP configuration, template inheritance, re-landing, and action pin authority.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 3b23e

This change repoints the notification workflow but currently leaves the action reference mutable and can send malformed notifications when a branch is deleted. These bounded security and correctness issues should be fixed or explicitly accepted before merging.

Poem

A rabbit checks the branch at dawn
The email path now carries on
Five minutes guard the waiting mail
A pinned action rides the trail
SMTP secrets stay asleep
While tidy workflow records keep

27-27: 🎯 Functional Correctness

Check secrets.SMTP_PORT

The repository does not expose the value of secrets.SMTP_PORT. With secure: true, the action uses implicit TLS and does not support STARTTLS; a value of 587 can therefore fail.

GitHub Actions push event branches filter branch deletion deleted true head_commit null official documentation

💡 Result:

The push event in GitHub Actions is triggered not only when commits are pushed, but also when a branch or tag is deleted [1][2][3]. When a branch is deleted, the push event payload includes a deleted field set to true, and the head_commit object is null [3]. Standard branch filters (such as on: push: branches: [...]) act on the ref being pushed. Because branch deletion is technically a push event affecting the ref, the workflow may still be triggered even if the branch name would otherwise match your filter. There is no native deleted: false filter available in the on.push configuration syntax to explicitly ignore these events [4][2]. To prevent your workflow from running when a branch is deleted, you can use a conditional check in the if field of your job or steps [1]. Example implementation: jobs: build: if: ${{!github.event.deleted }} runs-on: ubuntu-latest steps: - run: echo "This only runs if the branch was not deleted." Alternatively, if you need to handle deleted branches specifically, you can use the github.event.deleted boolean in your logic [3]. If you require a more complex setup, ensure your logic accounts for the fact that head_commit will be null during these deletion events [5][3][6].

Citations:


Exclude branch deletions explicitly.

A branch deletion can still match branches: ['**']. GitHub sets github.event.deleted to true and github.event.head_commit to null, so this job can send a notification with an empty Head msg. Add && !github.event.deleted to the job condition.

Pin the action to the immutable commit SHA.

@v0.1.0 is a mutable tag. The actions.lock entry does not make this reference immutable. Replace the tag with the verified full commit SHA for v0.1.0.
