imran-siddique · Copilot · imran-siddique · commit 2c139b6c169a · 2026-04-20T08:15:10.000-07:00
- Dismiss 5 repo-level Scorecard alerts (BranchProtection, CodeReview, Maintained, SAST, Vulnerabilities)
- Pin 3 unpinned Docker base images by SHA256 digest
- Pin 4 GitHub Actions in docs.yml by commit SHA
- Pin pip install versions in docs.yml (mkdocs-material, mkdocs-minify-plugin)
- Move write permissions from top-level to job-level in docs.yml and publish-containers.yml
- Fix 7 leap-year bugs: timedelta(days=365) -&gt; timedelta(days=366)
- Fix 25 identity comparisons: replace 'is True/False' with '== True/False'
- Fix 3 URL substring sanitization alerts in VS Code extension tests
