The chapters schema marks section.eyebrow / panelLabel / panelCode /
steps / copy as optional, but pages /agents/, /models/, /skills/
consume them — index access without narrowing failed astro check with
ts(18048). Same for SkillPackageExplorer: aria-selected was String(bool)
which widened to plain string and failed ts(2322) against
ButtonHTMLAttributes.
Fix: guard each required field with a helper that throws a clear
message on missing data, then read .en / .map from the narrowed value.
Page rendering is unchanged — dist/ HTML for all four files is
byte-identical before and after.
No any / as any / ! / @ts-ignore. Schema and tsconfig untouched.
Migrate the three remaining chapter pages to Astro routes, sharing
ChapterLayout and ChapterHero/TopBar/SiteFooter blocks. /summary/
already in place from task 12.
- /models/ -> src/pages/models.astro (zero JS)
- /agents/ -> src/pages/agents.astro (zero JS)
- /skills/ -> src/pages/skills.astro (one island: SkillPackageExplorer)
SkillPackageExplorer is the only JS across the four chapter pages;
moves vanilla skills/app.js content verbatim into the island. Uses
data-skill-file as the new hook (vanilla used data-package-file;
verify.mjs still asserts that on the legacy index.html).
Copy lives in src/content/chapters/{models,agents,skills}.json. All
four pages pass empty-text snapshot diffs against
.agents/snapshots/{models,agents,skills,summary}.txt. pnpm run verify
green: verify.mjs (16 sections), audit-ui.mjs, and check-tokens.mjs
(212 marked token-gap markers, 0 unsuppressed).
Did not touch ChapterLayout, the verification suite, contents of the
summary.astro file (it shipped with task 12), or the vanilla
chapters' HTML files at the repo root (verify.mjs still reads those).
