Changed to proper regex: (docs|wiki-content)/.* and docs/archive/.* - Fix link-check silently swallowing failures: remove || true from markdown-link-check invocations so broken links actually fail the build - Pin markdown-link-check to v3.14.2 to prevent supply chain attacks - Add .markdown-link-check.json config with retry-on-429, timeout, and ignore patterns for flaky URLs (actions/runs, settings, wiki pages) - Pin super-linter to SHA (12150456) instead of mutable v7 tag - Add permissions block (contents: read, statuses: write) to docs-validation.yml to prevent overly broad default token scope - Add concurrency group to cancel in-progress runs on rapid PR pushes - Optimize checkout: fetch-depth 1 plus targeted base SHA fetch - Fix patch diff: use PR base SHA instead of always diffing origin/main - Integrate scripts/check-docs-structure.sh into CI pipeline - Fix VALIDATE_MD to VALIDATE_MARKDOWN env var for super-linter v7 - Apply same fixes to auto-sync-docs.yml (identical copy-pasted bugs) * fix: address Gemini review comments on link-check config - Remove api.github.com from text/html header rule since the GitHub API serves JSON and would return errors with Accept: text/html - Remove 301/302 from aliveStatusCodes since markdown-link-check follows redirects by default and including them could mask broken destinations --- .github/workflows/auto-sync-docs.yml | 17 +++++++---- .github/workflows/docs-validation.yml | 44 +++++++++++++++++++++------ .markdown-link-check.json | 29 ++++++++++++++++++ 3 files changed, 74 insertions(+), 16 deletions(-) create mode 100644 .markdown-link-check.json diff --git a/.github/workflows/auto-sync-docs.yml b/.github/workflows/auto-sync-docs.yml index 043c2c21..8b1109ae 100644 --- a/.github/workflows/auto-sync-docs.yml +++ b/.github/workflows/auto-sync-docs.yml @@ -41,7 +41,8 @@ jobs: DOCS_COUNT=$(find docs -type f -name '*.md' !
