Summary by CodeRabbit

• New Features
  • Added validate --git <base> to limit warnings to changed documents and their dependents. Errors and selected bundle-wide warnings remain visible, and validation falls back to a full warning report if scoping fails.
  • Validation results now include document counts, including the scoped count when applicable.
• Bug Fixes
  • Validation treats links and resources that resolve outside the bundle as missing.
  • YAML warnings and command errors are handled more safely, and bundle reads are limited to 32 concurrent files.
• Documentation
  • Added guidance and examples for Git-scoped validation and running validation with npx.

📝 Walkthrough

Walkthrough

The change adds validate --git warning scopes while keeping errors bundle-wide. It also adds bundle-contained symlink checks and updates Git invocation, input handling, concurrent reads, and CLI output formatting.

Changes

Validation and security hardening

Layer / File(s)	Summary
Shared input and resource safeguards AGENTS.md, CHANGELOG.md, src/security.ts, src/parse.ts, src/limits.ts, src/index.ts, src/graph.ts, src/mermaid.ts, test/pollution.test.ts, test/parse.test.ts, test/size-limit.test.ts	Option reads now use own properties. YAML frontmatter is copied to null-prototype objects. Graph loading uses a 32-read concurrency limit. Tests cover these behaviors.
Scoped validation and path containment src/validate.ts, test/validate.test.ts	validate accepts a document scope for warning reporting, while retaining all errors and selected bundle-wide warnings. Resource and link checks reject targets that resolve outside the bundle.
Git command safeguards src/git.ts, SECURITY.md, test/git.test.ts	Git commands disable core.fsmonitor; diff commands also disable external diff drivers. The security policy documents Git configuration limitations.
Git-scoped validation CLI AGENTS.md, CHANGELOG.md, README.md, bin/okph.ts, test/cli.test.ts	The CLI accepts --git for validate and scopes warnings to changed documents and dependents. It retains bundle-wide errors and specified warnings, reports scope counts, and falls back to full validation when scope calculation fails.
CLI output escaping bin/okph.ts, test/cli.test.ts	Markdown link labels escape HTML characters. CLI errors use terminal-safe formatting.

Merge Risk: 🔵 Low · up to 74bc9

Callers that explicitly disable navigation links can receive extra affected documents. This is a bounded issue, but the option should be corrected before relying on those results.

- Line 41: Update the includeNav check in the traversal edge selection to enable
navigation edges only when options.includeNav is true; an own includeNav
property set to false must continue filtering reserved files such as index.md
