# 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.

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.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Exclude deleted branches from notification delivery.

Line 37 allows a branch-deletion push event to send an email. The push payload marks this case with deleted, and head_commit can be null. Add a deletion guard so the workflow does not send a notification with missing commit data. (docs.github.com)

Proposed fix 
-    if: ${{ vars.PUSH_EMAIL_ENABLED == 'true' }}
+    if: ${{ vars.PUSH_EMAIL_ENABLED == 'true' && github.event.deleted == false }}

In @.github/workflows/push-email-notify.yml at line 37, Update the workflow job
condition using PUSH_EMAIL_ENABLED to also require that the push event is not a
branch deletion, checking the payload’s deleted flag before sending
notifications.
