Snippet Fidelity v0.1.0

Snippet Fidelity's first public pre-release verifies that documentation copy buttons preserve the
text maintainers intended to ship.

Highlights

• Compares canonical text, rendered code, copy-handler payloads, and the browser clipboard at
  Unicode code-point precision.
• Detects terminal newlines, indentation loss, tab/space substitution, invisible characters,
  punctuation substitution, and Unicode normalization changes.
• Emits bounded Markdown, JSON, and JUnit evidence without including complete snippets by default.
• Exercises real copy controls in Chromium and refuses ambiguous selectors.
• Ships a six-case adversarial fixture corpus: one correct control and five intentional regressions.

Install

npm install --save-dev https://github.com/WLDKK/snippet-fidelity/releases/download/v0.1.0/snippet-fidelity-0.1.0.tgz
npx playwright install chromium
npx snippet-fidelity audit https://docs.example.com/

Verification

• Node.js 24.14.0 and pnpm 10.18.0
• 5 test files and 19 tests passed, including real Chromium end-to-end coverage
• type check, build, package dry-run, and production dependency audit passed
• no known production dependency vulnerabilities reported at release time

Known limitations

• Chromium is the only supported browser in 0.1.x.
• Explicit selectors and canonical text or files are required for a dependable source-aware release
  gate.
• Automatic discovery is intended for reconnaissance and regression triage.
