build(deps): bump pymdown-extensions from 10.16.1 to 10.21.3 in /docs

[dependabot]

Bumps pymdown-extensions from 10.16.1 to 10.21.3.

Release notes

Sourced from pymdown-extensions's releases.

10.21.3

• FIX: Fix regression that allows a snippet to be loaded outside of the base path using directory traversal when restrict_base_path is enabled (the default). Found by @​gistrec.

10.21. 2

10.21.2

• FIX: Highlight: Latest Pygments versions cannot handle a "filename" for code block titles of None.

10.20.1

• FIX: Quotes: Ensure the first class for callouts (the alert type) is always rendered lowercase.

10.21

• NEW: Caption: Add support for specifying not only IDs but classes and arbitrary attributes. Initial work by @​joapuiib.
• FIX: MagicLink: Fix a matching pattern for Bitbucket repo.

10.20

• NEW: Quotes: New blockquotes extension added that uses a more modern approach when compared to Python Markdown's default. Quotes specifically will not group consecutive blockquotes together in the same lazy fashion that the default Python Markdown does which follows a more modern trend to how parsers these days handle block quotes.

  In addition, Quotes also provides an optional feature to enable specifying callouts/alerts in the style used by GitHub and Obsidian.

10.19.1

• FIX: Arithmatex: Fix issue where block $$ math used inline within a paragraph could result in nested math parsing.

10.19

• NEW: Emoji: Update Twemoji to use Unicode 16.
• NEW: Critic: Roll back view mode deprecation as some still like to use it, though further enhancements to this mode are not planned.

10.18

• NEW: Critic: view mode has been deprecated. To avoid warnings or future issues, explicitly set mode to either accept or reject. In the future, the new default will be accept and the view mode will be removed entirely.
• FIX: Block Admonition: important should have always been available as a default.

10.17.2

• FIX: Blocks: Blocks extensions will now better handle nesting of indented style Admonitions, Details, and Tabbed

Dependabot PR: pymdown-extensions 10.16.1 → 10.21.3

Scope: Single-file change in docs/uv.lock — version + hash bump
CI: All green (build ✓, ruff ✓, spellcheck ✓)
Build: uv sync && mkdocs build --strict passes cleanly
Live test: Docs site served and rendered successfully — no JS errors, no broken features

Security Note 🔐

This upgrade includes a fix for CVE-2026-46338 (directory traversal in pymdownx.snippets with restrict_base_path). The repo uses pymdownx.snippets in mkdocs.yml — this is a security-relevant update.

🔴 Breaking Changes

The release notes for pymdown-extensions between 10.16.1 and 10.21.3 include:

• 10.18: Critic view mode deprecated (deprecation warning emitted, but backwards-compatible)
• 10.20: New Quotes extension added (optional, not enabled)
• 10.21.3: Security fix for Snippets directory traversal (CVE-2026-46338)

This project does not use Critic or the new Quotes extension in mkdocs.yml, so no breaking impact. The Snippets fix is a pure security improvement.

Verdict: ✅ No breaking changes detected for this project.

---

⚠️ Issues Found

No issues found. The diff is a standard lockfile update:

• Version string changed correctly
• sdist hash updated (256 -> 256)
• wheel hash updated (256 -> 256)
• Package URL paths updated correctly
• uv lock --check confirms lockfile is consistent

---

🔬 Logical / Bug Analysis

Nothing to flag. This is a straightforward dependency bump managed by Dependabot:

• Hash integrity verified (uv lock --check passes)
• No config changes needed for this version jump
• All transitive dependencies unchanged

💡 Suggestions

• Consider enabling Dependabot auto-merge for uv minor/patch updates in /docs -- this is a low-risk pattern that would benefit from automation.
• This lockfile update only affects the docs build pipeline, not the main runtime, so it is safe to merge without extended review.

🔍 Automated Code Review

📋 Executive Summary

This Dependabot PR updates the indirect docs dependency pymdown-extensions from 10.16.1 to 10.21.3 by changing only its locked version, source artifact URLs, hashes, sizes, and upload timestamps in docs/uv.lock. The change is internally consistent, the repository’s enabled pymdownx extensions import successfully, and a strict documentation build plus browser smoke test passed.

The upgrade is security-relevant because this repository enables pymdownx.snippets in docs/mkdocs.yml:131; upstream 10.21.3 includes the fix for the default restrict_base_path directory-traversal regression. No compatibility regressions were found in the configured extensions.

🔴 Breaking Changes

✅ No breaking changes detected for this repository.

• No source, API, database, configuration, serialization, or public-interface code changed.
• docs/mkdocs.yml configures pymdownx.highlight, inlinehilite, snippets, superfences, details, and tabbed; the installed 10.21.3 package imported the exercised snippets, superfences, and highlight modules successfully.
• The lockfile is resolvable and consistent with the project manifest; uv lock --check --offline passed.

⚠️ Issues Found

No blocking or warning-level issues found.

1. ℹ️ Reviewed change — docs/uv.lock:462-470 — the version, PyPI artifact URLs, SHA-256 hashes, package sizes, and timestamps move together from 10.16.1 to 10.21.3. The locked resolver installed exactly pymdown-extensions==10.21.3.
2. ℹ️ Security outcome — docs/mkdocs.yml:131 — pymdownx.snippets is enabled, so this upstream patch is relevant to the repository’s actual docs configuration.

No inline comments were posted because the one-file diff contains no actionable code defect.

🔬 Logical / Bug Analysis

• Scope control: git diff origin/main...HEAD --stat reports exactly one changed file, with 3 insertions and 3 deletions. Commit history contains one Dependabot commit at the requested head SHA c696a193762852945166a7222d1b092b678668b1.
• Lockfile integrity: uv lock --check --offline completed successfully and uv tree --locked --offline resolves pymdown-extensions v10.21.3 with its expected markdown and pyyaml dependencies.
• Build behavior: uv sync --locked created a clean environment and installed 44 packages, including pymdown-extensions==10.21.3. uv run mkdocs build --strict completed without build errors.
• Runtime surface exercised: imports of pymdownx.snippets, pymdownx.superfences, and pymdownx.highlight succeeded under the locked environment.
• Regression checks: git diff --check was clean; no conflict markers or credential-like additions appeared in the diff. The head includes origin/main (git merge-base --is-ancestor origin/main HEAD succeeded).

👥 Human Review Feedback

No human review feedback or inline review threads exist on this PR. Existing comments and prior formal approvals are from @hermes-exosphere; GraphQL reports zero review threads, so there were no bot threads eligible for resolution and no human threads to leave open.

---

💡 Suggestions

• Consider enabling Dependabot auto-merge for compatible low-risk docs lockfile patch/minor updates after required CI passes, subject to the repository’s merge policy.
• The build printed an upstream Material-for-MkDocs informational advisory about a future MkDocs 2.0 ecosystem change. It is not caused by this PR and does not affect the successful strict build, but it may merit separate dependency-maintenance tracking.
