Replaces dawidd6/action-send-mail with hyperpolymath/smtp-notify-action v0.2.0 (tag commit ede1191ef6ff3ac02c4f4d9efdf837ee517e11d7), per the 2026-09-02 ruling (standards spec §5.5/§9, PR hyperpolymath/standards#725). The whole file is replaced with the rsr-template-repo canonical, which — besides the uses: line — restricts the trigger to branch pushes (tag and deletion payloads mislabel Branch:/head_commit), sets timeout-minutes: 5, carries a deliberately per-run concurrency group, and grants only contents: read. How many of those are actual changes here depends on how far this repo's copy had drifted — read the diff, not this list. Dormant gating on vars.PUSH_EMAIL_ENABLED == 'true' is unchanged. Line 1 SPDX header kept as it was.

Review Change Stack

📝 Summary

Summary by CodeRabbit

  • Chores
    • Restored email notifications for branch push events.
    • Improved notification reliability by preventing overlapping runs and limiting processing time.
    • Updated the notification delivery service and refined workflow access permissions.

Walkthrough

The push-email workflow was re-landed with branch-only triggers, per-run concurrency, reduced permissions, a five-minute job timeout, and a replacement SMTP notification action.

Changes

Push email notification workflow

Layer / File(s) Summary
Workflow event and run controls
.github/workflows/push-email-notify.yml
The workflow now runs for branch pushes only. Each run has an independent concurrency group with cancellation disabled. The workflow keeps only contents: read permission.
Notification delivery job
.github/workflows/push-email-notify.yml
The notify job has a five-minute timeout. The email step now uses hyperpolymath/smtp-notify-action@v0.2.0.

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

Merge Risk: 🟡 Moderate · up to bfce1

Email notifications may fail or expose SMTP credentials to code selected by a moved tag. Pin the approved commit and confirm the configured SMTP endpoint supports implicit TLS before merging.

Poem

A rabbit checks the branch at dawn
Each email run hops safely on
Five minutes marks the SMTP flight
Permissions stay small and light
The notification lands just right

16-16: 🎯 Functional Correctness

No change is required for branch deletion. GitHub Actions does not trigger a push workflow when a branch is deleted. Although the underlying webhook payload can contain deleted: true and head_commit: null, that payload does not reach this job through the configured push trigger.

gh actions-lock actions.lock enforcement runtime tag commit GitHub Actions

💡 Result:

GitHub Actions does not natively read or enforce the.github/workflows/actions.lock file at runtime [1][2]. The actions.lock file is a tool-maintained record used by the gh actions-lock CLI tool and other external auditing infrastructure to track, verify, and document resolved dependency pins [3][4][5]. Because GitHub Actions ignores this file during execution, referencing actions by mutable tags (e.g., @v4) in your workflow files remains a runtime risk; the runner will always execute whatever commit the tag currently points to, regardless of what is recorded in actions.lock [1][2]. To enforce immutability at runtime, you must pin your actions to a full-length 40-character commit SHA directly within your workflow files [6][7]. For organizations requiring strictly enforced security, GitHub provides a native, policy-based mechanism to enforce SHA pinning [8]. When this organization-level policy is enabled: 1. It mandates that all actions (including internal sub-actions) must be pinned to a full commit SHA [8][9]. 2. Any workflow attempting to use a tag or branch reference will fail at execution time [8][9]. In practice, many teams combine these approaches by: - Using inline SHA pins in workflow files to ensure runtime immutability and compliance with organization-level enforcement policies [2][9]. - Including the desired version as a trailing comment (e.g., uses: actions/checkout@sha... # v4.2.2) to maintain compatibility with tools like Dependabot, which use these comments to track and propose updates [2][10][7]. - Using the gh actions-lock tool or other CI checks to audit and validate that the SHAs used in workflows match the expected versions recorded in their dependency lockfile [3][11][2]. Top results: [3][1][2][8][9]

Pin the action to the approved commit.

GitHub Actions does not read .github/workflows/actions.lock when resolving uses. A later tag move can therefore replace the action that receives the SMTP credentials. .github/workflows/workflow-linter.yml also rejects non-SHA references. Use ede1191ef6ff3ac02c4f4d9efdf837ee517e11d7 directly. (docs.github.com)

🌐 Web query:

hyperpolymath/smtp-notify-action v0.2.0 action.yml secure true SMTP port implicit TLS STARTTLS

💡 Result:

There is no publicly documented GitHub Action named hyperpolymath/smtp-notify-action. Extensive searching of the hyperpolymath GitHub organization reveals that it utilizes the popular third-party action dawidd6/action-send-mail to handle SMTP notifications within its repositories [1][2][3][4][5]. Regarding the technical configuration of SMTP actions in GitHub workflows (such as dawidd6/action-send-mail or similar tools), the parameters secure, SMTP ports, and TLS modes function as follows: 1. secure: true: This setting enables implicit TLS (SMTPS). It is typically paired with port 465, where the TLS handshake is initiated immediately upon connection, before any SMTP commands are sent [6][7]. 2. STARTTLS: This is a different mechanism used to upgrade an insecure connection (typically on port 587 or 25) to a secure one using the STARTTLS command after the initial plaintext connection is established [6][7]. 3. Configuration Best Practices: - Use secure: true with port 465 for implicit TLS [6][7]. - If using port 587, the connection is usually established as plaintext first, followed by a STARTTLS command. In many GitHub actions, this is handled by setting secure: false or by specifically omitting implicit TLS flags, depending on the action's internal implementation [6]. - Avoid enabling implicit TLS (secure: true) on ports designed for STARTTLS, as this can cause connection errors [6]. If you are encountering issues with a specific workflow, ensure you are referencing the correct action name (e.g., dawidd6/action-send-mail) and that the secure configuration matches the requirements of your specific SMTP provider's port [6].

Verify the SMTP transport mode after migration.

If SMTP_PORT is a STARTTLS-only port such as 587, secure: true can fail because v0.2.0 uses implicit TLS and does not negotiate STARTTLS. Confirm that SMTP_HOST and SMTP_PORT identify an implicit-TLS endpoint, normally port 465.
