Lab

Write-ups with measured numbers.

Numbers taken from records rather than recollection, and a black box taken apart on screen. Every input is shown, so a figure is something to check rather than to trust.

The line's changelog →
  1. Claude Code First
    Rule pages print literal asterisks around every normative sentence that holds an italic term

    Rule pages render a bold normative sentence holding an italic term as strong with em inside, and a test fails on any rule page that prints two asterisks.

  2. Claude Code First
    The site header links neither alegauss.github.io nor the GitHub repository, unlike every other alegauss site

    Every page's header carries the "part of alegauss" chip to alegauss.github.io and a GitHub button to the repository, and a test fails on a header without either.

  3. Claude Code First
    markdownlint lints the governed docs/DEFERRED.md, and fails on a blank line roadkeep wrote there

    markdownlint now ignores docs/DEFERRED.md beside the other four governed files, and its gate passes with the file as roadkeep wrote it.

  4. Claude Code First
    The guide and specification pages carry their own 892-line stylesheet, outside the design system

    The guide and spec pages take fonts, tokens and site.css at 2026.3.22, re-keyed to the mark's rose, with analytics behind consent; style.css keeps only this site's own blocks.

  5. Claude Code First
    The site shows no mark of its own: no favicon, no logo in the header, no social card

    Every built page links icon.svg and carries og:image, the guide header shows the mark, and a stdlib-drawn og.png renders the mark and title.

  6. Claude Code First
    the files-over-APIs open question names what would settle it, and nothing has been measured against it

    F410 grades Shio's SH1141 at R1/S3: files cost 1.29x less and the agent writes 3.1x less; AP's open question and the guide say so, and corpus.md now lists a commit cited past a pin.
