Ten git worktrees each carried their own 225 MB node_modules (1.1 GB across five) and paid 11s per `npm ci`. pnpm hardlinks from a shared store: the same five worktrees cost ~250 MB total, and a fresh install is 4s. What changed beyond the mechanical rename: - `overrides` moved to `pnpm-workspace.yaml`. pnpm 11 does not read the `pnpm` field in package.json *or* npm's top-level `overrides`, and it fails silently — the vite/defu/language-server pins would have quietly stopped applying. - Build scripts are blocked by default in pnpm; esbuild and sharp are allowed explicitly via `allowBuilds` (renamed from `onlyBuiltDependencies` in 11). - `packageManager` + `engines` pin the toolchain. - gate.sh rejects a package-lock.json/yarn.lock/bun.lock outright, so an agent running `npm install` out of habit fails loudly instead of building a second, divergent dependency tree. - CI bootstraps pnpm with `npm install --global pnpm@11.25.0` rather than corepack (unbundled as of Node 25) or pnpm/action-setup (this self-hosted act-runner has never run a job; fetching a third-party action is not something to discover on the first one). Two pre-existing CI bugs fixed while in the file: - the gate installed with `npm install --package-lock=false`, which discarded the lockfile the previous session had just fixed. - the visual-regression step imported `playwright`, which is not a dependency, and `visual-regression.mjs` has no compare mode anyway — in CI it overwrote its own baselines and passed unconditionally. Removed with a comment; it comes back when it can diff. The `publish` job is now manual (`workflow_dispatch`). During the migration dist/ holds three HTML files against the live pages branch's ten, so publishing on every push to main would take the site down to a stub. Restore at task 20. HANDOVER.md's incident log still says npm where it describes what happened at the time; that is history, not a missed rename. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Migrate one hand-written HTML page of the ai-for-dummies site to an Astro
|
|
route without changing its URL, content, or JS budget. Use for any page-level
|

migration task.

# Migrating a page to Astro
|
|
|
|
## Snapshot first, migrate second
|
|
|
|
The snapshot is the only objective evidence that no content was lost.
|
|
|
|
```bash
|
|
pnpm run serve & # vanilla site on :4173
|
|
node .agents/scripts/snapshot-route.mjs http://localhost:4173/models/ \
|
|
> .agents/snapshots/models.txt
|
|
```
|
|
|
|
Screenshot the same route at 560 / 800 / 1100 / 1600 px as well.
|
|
|
|
## Migrate
|
|
|
|
```bash
|
|
cp .agents/templates/pages/chapter.astro src/pages/models.astro
|
|
```
|
|
|
|
Then, in order:
|
|
|
|
1. Move markup into the layout + components. Reuse existing components before
|
|
creating new ones.
|
|
2. Move copy into `src/content/`. Both `en` and `pt`, copied literally — never
|
|
retyped.
|
|
3. Move page CSS into component `<style>` blocks. Do **not** port
|
|
`responsive.css` wholesale; take what this page needs and prove the rest
|
|
dead.
|
|
4. Keep every `data-*` hook. `verify.mjs` asserts many of them by name
|
|
(`data-phase`, `data-tree`, `data-route`, `data-model-provider`, …).
|
|
5. Keep every ARIA attribute and the `<title>` / `<meta name="description">`.
|
|
|
|
## The URL must not change
|
|
|
|
Served from `/ai-for-dummies/`, so `base` is set in `astro.config.mjs`. Never
|
|
hand-write an internal absolute path; use `import.meta.env.BASE_URL`.
|
|
|
|
Trailing slashes matter. `/models/` must not become `/models`.
|
|
|
|
If the page honours query params (the review desk uses `?author=`, `?skill=`,
|
|
`?view=`, `?file=`, `?compare=`, `?render=`), they must still work — they are
|
|
documented in the page footer and shared externally.
|
|
|
|
## Prove it
|
|
|
|
```bash
|
|
pnpm run build
|
|
node .agents/scripts/snapshot-route.mjs dist/models/index.html > /tmp/after.txt
|
|
diff .agents/snapshots/models.txt /tmp/after.txt # empty, or justify every line
|
|
node scripts/audit-ui.mjs
|
|
pnpm run verify
|
|
```
|
|
|
|
Then screenshots at the same four widths, and
|
|
[`../../checklists/before-page.md`](../../checklists/before-page.md).
|
|
|
|
## JS budget
|
|
|
|
A page that shipped zero JS must still ship zero. Check the build output. If
|
|
your migration added a `client:load` to a static page, you did it wrong.
