chore(deps): bump the actions group across 1 directory with 2 updates

[dependabot]

Bumps the actions group with 2 updates in the / directory: github/codeql-action and hyperpolymath/smtp-notify-action.

Updates github/codeql-action from 4.37.9 to 4.38.0

Release notes

Sourced from github/codeql-action's releases.

v4.38.0

• On GitHub-hosted runners, the CodeQL Action now deletes unused CodeQL bundles from the toolcache before downloading a different bundle, which frees up disk space for the analysis. We expect to roll this change out to everyone in September. #4124
• The CodeQL Action now supports CodeQL releases that are compatible with Linux Arm64 and downloads the native linux-arm64 CodeQL bundle when available. #4072
• Update default CodeQL bundle version to 2.27.0. #4129

Updates hyperpolymath/smtp-notify-action from 0.2.0 to 0.3.0

Release notes

Sourced from hyperpolymath/smtp-notify-action's releases.

v0.3.0

Static, byte-reproducible smtp-notify binaries. CI rebuilt them from this tag and verified they hash to exactly the SHA-256 pins inside this tag's action.yml before publishing.

[IMPORTANT]

main is not a release, and pinning @main is not supported.

Between a release commit landing on main and its tag being pushed, action.yml on main names assets that do not exist yet, so @main fails at the download step. This window is unavoidable rather than an oversight: the release workflow refuses to publish unless the asset URL in the tagged commit already names the tag being released, so the commit must precede the tag. The window is minutes long and is one more reason @main is not a supported ref.

Pin a tag, or a commit SHA that is an ancestor of one.

=== Added

• STARTTLS on the submission port. secure: false or secure: starttls now starts in the clear on port 587 and upgrades the same connection in place per RFC 3207, including the mandatory second EHLO after the upgrade. The upgrade is not opportunistic: a server that does not advertise STARTTLS fails the step, and that check runs before the command is sent, so no credential is ever written to a cleartext stream. Certificate verification is identical on both TLS paths.
• EHLO capability parsing (issue #9). The EHLO reply is parsed into a Capabilities value — STARTTLS, the AUTH mechanism list (including the Exchange AUTH=LOGIN spelling), SIZE and 8BITMIME — and an AUTH failure now names what the server actually advertised. A mechanism mismatch and a wrong password no longer look alike in the log.
• The proven state machine now carries two tables, selected by transport, each proven separately: the implicit-TLS table is proven to contain no upgrade rows, and the STARTTLS table is proven to reach them from the start state. A row that is present but unreachable would have authenticated in the clear while every prior proof stayed green.
• AUTH LOGIN, and mechanism selection (issue #10). The mechanism is chosen from the advertised list instead of assumed: PLAIN where offered (one round trip), LOGIN otherwise. On the STARTTLS path the choice is made from the post-upgrade advertisement, so rewriting the cleartext greeting cannot steer it. A server offering neither is refused before any credential byte is written, naming what was on offer. XOAUTH2 is not implemented and is not planned — it needs an OAuth token, which a repository secret cannot supply. The two 334 challenges are driven outside the proven table by design; the terminal reply is still checked against it. See KNOWN-DEFECTS.adoc, "Scope of the proof".

Microsoft 365 and Google Workspace are reachable from this release on port 587 with secure: starttls. Port 465 has no listener at Microsoft 365 and never will work. The STARTTLS handshake is verified against both providers' live submission ports — smtp.office365.com:587 and smtp.gmail.com:587, on 2026-09-09 —
