# PUSH_EMAIL_ENABLED=true (the single on/off switch). Addresses are pre-filled;
# sending needs the org SMTP secrets (SMTP_HOST/PORT/USER/PASS). Inherited by
# new repos from the template; placed on existing repos by the farm sweep.

# Re-landed after the 2026-07-20 notification-storm freeze (removed in
# 09f94c5), now on hyperpolymath/smtp-notify-action: Node-free, the SMTP
# session is Idris2-specified and machine-checked, the binary is Zig-built,
# byte-reproducible, and SHA-256-pinned inside the action itself.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Exclude deleted branches from the notification job.

GitHub includes branch deletion in the push event, and branch filters match the Git ref name. Therefore, branches: ['**'] still matches a deleted refs/heads/... ref. The workflow can send a false notification for git push --delete, despite the stated branch-push-only behaviour. (docs.github.com)

Add !github.event.deleted to the existing job condition.

Suggested fix 
 jobs:
   notify:
-    if: ${{ vars.PUSH_EMAIL_ENABLED == 'true' }}
+    if: ${{ !github.event.deleted && vars.PUSH_EMAIL_ENABLED == 'true' }}

minimal, and validate.

In @.github/workflows/push-email-notify.yml at line 15, Update the notification
job condition in the workflow to require github.event.deleted to be false, while
preserving the existing all-branch filter and other conditions so deleted branch
push events do not trigger notifications.

concurrency:
# Deliberately per-RUN, so no run is ever queued behind another and none is
# ever cancelled. Do NOT "tidy" this into a shared group such as
# ${{ github.workflow }}-${{ github.ref }}. GitHub's workflow-syntax docs:
# "By default, any existing pending job or workflow in the same concurrency
# group will be canceled and the new queued job or workflow will take its
# place." That happens regardless of cancel-in-progress, which governs only
# the RUNNING job. On this workflow it silently loses a notification email,
# with no error anywhere. Every run here reports a DISTINCT commit, so there
# is no redundant work for a concurrency limit to remove.
# The docs also offer `queue: max` (up to 100 pending); not used, because 100
# is still a cap whereas a per-run group needs none.
# Verified with zizmor 1.30.0: deleting this block raises concurrency-limits;
# this form silences it exactly as a shared group would.

Confirm SMTP compatibility before merging.

With secure: true, hyperpolymath/smtp-notify-action@ede1191ef6ff3ac02c4f4d9efdf837ee517e11d7 requires implicit TLS and AUTH PLAIN. An SMTP endpoint that requires STARTTLS or another authentication mechanism may cause every notification to fail. Confirm that the existing SMTP_HOST and SMTP_PORT support both requirements.
