[dobby-coder]

Security vulnerabilities (fix first)

None detected.

Outdated packages

Package	Current	Latest	Bump type	Notes
Microsoft.NET.Test.Sdk	18.5.1	18.7.0	minor	Test SDK — affects E4A.PostGuard.Tests only

Worker instructions

CVEs first (all in PR, severity order) — none at this time.

Then minor/patch updates:

• Bump Microsoft.NET.Test.Sdk from 18.5.1 to 18.7.0 in tests/E4A.PostGuard.Tests/E4A.PostGuard.Tests.csproj

Majors individually (don't skip) — none at this time.

Build and test after each batch.

Create a DRAFT PR titled "chore: update dependencies", add reviewer rubenhensen, and include Closes #<this issue> on its own line in the PR description.

Monitor CI; fix any failures; when CI is green run gh pr ready to mark it ready for review.

Dobby looked at this but isn't routing it anywhere: Event is a bare /dobby comment from dobby-coder bot itself with no command or context — dropping to avoid self-triggered loop If that's wrong, ping Dobby again or be explicit with /dobby review, /dobby fix, or /dobby ask.
