# Handover — Astro refactor, session of 2026-09-05

Phase 0 is done, merged, and green. Tasks 01–04 are all in `main`. The project
now runs on **pnpm**, not npm. Nothing has been pushed: `main` is **23 commits
ahead of `origin/main`**.

## Where the work is

| Branch                              | Head          | State                               |
| ----------------------------------- | ------------- | ----------------------------------- |
| `main`                              | see `git log` | 01–04 merged, gate green under pnpm |
| `refactor/task-01-scaffold`         | `71021e6`     | merged                              |
| `refactor/task-02-tokens`           | `c9ec9e3`     | merged                              |
| `refactor/task-03-verification-net` | `2e79aac`     | merged                              |
| `refactor/task-04-content-schema`   | `b554f87`     | merged (gate verified before merge) |

All four merged with `--no-ff` and **zero conflicts**. The four worktrees in
`~/Projects/af-task-0*` still exist and still hold npm-era `node_modules`; they
are stale. `~/Projects/af-task-02/before/` still holds 29 MB of misplaced
untracked screenshots — delete or move them before removing that worktree.

## What each task actually produced

**01 — scaffold (Codex).** Astro 5.5 with `base: '/ai-for-dummies'`, strict TS,
`BaseLayout.astro`, `summary.astro` as the single smoke page, lint/format/husky
configs, `.gitea/workflows/`, rewritten publishing section in
`docs/operations-guide.md`, `hands-on/` copied verbatim into `public/`. Build
passes, gate passes, hooks verified live, 42/42 assertions intact.

**02 — tokens (Gemini).** `src/styles/tokens.css` and `src/styles/base.css` only
— 43 lines. It did **not** touch the legacy CSS, deliberately: rewriting
`styles.css` would break `verify.mjs`'s exact-string assertions. So the three
drifting palettes are now resolved _in the new token layer_, while the live site
still runs on the old values. That is the correct scope, but it means the
consolidation is not proven visually yet.

**03 — verification net (Codex).** `.agents/scripts/visual-regression.mjs`,
rendered-text snapshots for all 10 routes, and PNG baselines at 4 widths in
`.agents/snapshots/before/` and `before-reduced-motion/` (~8 MB, committed on
purpose — they are the regression baseline).

**04 — content schema (MiniMax).** `src/content/config.ts` with eight empty
collections and a strict `localized({en, pt})` helper. No content moved; that is
tasks 05 and 06.

## Things I fixed that the plan got wrong

- `AGENTS.md` listed `package-lock.json` under **Never touch**, meaning never
  hand-edit. Task 01 read it as never create and shipped with
  `--package-lock=false`. `npm ci` — which is how every worktree spun up at the
  time — cannot work without it. Wording corrected; lockfile committed.
- The first lockfile was reconstructed from a `node_modules` installed without
  one, so its entries had no `resolved`/`integrity` and `npm ci` failed with
  `ETARGET tinyglobby@0.2.17`. Regenerated from a clean install.
- `.husky/commit-msg` rejected `build:` and `revert:`. Both are standard
  conventional types. Added.
- `launch.sh` read the agent name with `[a-z-]*`, which cannot match
  `content-i18n-migrator`. Tasks 04/05/06 silently fell back to
  `astro-architect`. Fixed to `[a-z0-9-]*` and made it fail loudly instead of
  guessing. Task 04 was relaunched under the right agent.

## Things the agents got wrong, and what I did

- **Task 03 went outside its brief.** It rewrote `scripts/audit-ui.mjs` to ban
  external CSS dependencies — a sound check that the pre-existing malformed
  `@font-face` in `styles.css` violates, so it left the gate red for every
  downstream task. Reverted in `2e79aac`; the snapshot net was kept. **The check
  should come back once the font decision is made.**
- **Task 03 rebased instead of branching**, flattening task 01's merge into four
  duplicate commits with new SHAs — the same divergent-history trap that broke
  the `pages` branch. Replayed onto the proper base; task 01 is an ancestor
  again. Worth adding to `.agents/rules/git-worktrees.md`: **never rebase a task
  branch onto anything.**
- **Task 02 left 29 MB of screenshots in `~/Projects/af-task-02/before/`** —
  untracked, and in the wrong place (`.agents/snapshots/` is the right one). Its
  report claims the screenshot box is unticked while the files exist. Delete
  them or move them; do not commit them where they are.

## Still open from task 01's own report

- ~~Real-host smoke test of `/ai-for-dummies/summary/`~~ — **done**, see
  "Resolved: the base path serves correctly on the real host" above.
- No Playwright locally, so screenshot comparison still cannot run anywhere.
  `visual-regression.mjs` also has no compare mode, so it is out of CI until it
  grows one. See `.agents/rules/gates.md`.

## The decision that is still yours

`styles.css:1` has an `@font-face` whose `src:` points at a Google Fonts
_stylesheet_, not a font file. Manrope and DM Mono have therefore never
rendered; the site has always been Arial and generic monospace. Self-hosting
them during the migration would silently redesign the site. Task 02 defaulted to
matching what renders today. Decide explicitly, then task 19 can restore the
external-CSS assertion. See `.agents/context/design-system.md`.

## Next steps, in order

1. **Decide the font question** (see below). It blocks task 19 and it is now the
   only thing here that needs a human.
2. Fan out phase 1 and 2:
   ```bash
   .agents/scripts/launch.sh 05 content-guide   --base main
   .agents/scripts/launch.sh 06 content-review  --base main
   .agents/scripts/launch.sh 07 primitives      --base main
   ```
   All three are unblocked now that 02 and 04 are in `main`. After 07 lands,
   08-11 run four at a time. **Task 07 is the routing calibration point** -
   judge it before committing to MiniMax for the other twelve.
3. Clean up the four merged worktrees and branches in `~/Projects/af-task-0*`.
   `~/Projects/af-task-02/before/` holds 29 MB of misplaced untracked
   screenshots; delete or move them first.

## Resolved: the base path serves correctly on the real host

This was the #1 production-only failure mode and it is now **verified against
the live Pages Server**, not just `pnpm run preview`.

Method, which is reusable and costs no downtime: the Astro `dist/` was published
to the `pages` branch **additively** — `_astro/` plus a single page at
`_verify/summary/`, both paths previously unused, so no existing file was
touched and all ten live pages stayed up throughout. Results:

- `/ai-for-dummies/_verify/summary/` → 200, and it really is the Astro page
  (`<title>AI For Dummies — Route map</title>`), not a 200-ing error page.
- `/ai-for-dummies/_astro/chapters.PwjFDHFw.css` → 200 `text/css`. **This is the
  actual base-path proof**: Astro emits base-prefixed _absolute_ asset URLs, and
  the server resolves them.
- `/ai-for-dummies/_verify/summary` (no trailing slash) → 307 to the slashed
  form, which matches `trailingSlash: 'always'`.

The probe was force-pushed away immediately; `pages` is back at `37a1e48`.

Note for whoever publishes next: **the Pages Server caches for ten minutes**,
keyed on path. A deleted file keeps serving 200 until the cache expires, and a
`?v=<sha>` query does not bust it. See `docs/operations-guide.md` step 6.

## Carried over from the phase 0 review

Found while reviewing the four diffs, none of it blocking, none of it fixed:

- **`public/hands-on/` is a byte-identical copy of `hands-on/`** with no sync
  mechanism. Two trees will drift. Symlink, or copy as a build step.
- **`--bp-*` tokens cannot work.** CSS custom properties do not resolve inside
  `@media` queries. The real enforcement is `check-tokens.mjs`'s
  `ALLOWED_BREAKPOINTS` allowlist; the variables are decoration and will mislead
  whoever writes the first responsive component.
- **`tokens.css` has no font tokens at all**, and the scale skips `--step-2` and
  `--step-3`. Downstream of the font decision.
- **`visual-regression.mjs` has no compare mode.** It only captures. It is out
  of CI for that reason — see `.agents/rules/gates.md`.
- `src/content/config.ts` uses the legacy `type: 'data'` API. Astro 5
  auto-converts it to a glob loader and it works; prefer explicit
  `file()`/`glob()` loaders in `src/content.config.ts` when 05/06 touch it.

## Running an agent

`.agents/scripts/launch.sh <nn> <slug> [--base ref] [--cli codex|agy|mm] [--fg]`

Routing is automatic: Codex for 01/03/15/16/19, `agy` (Gemini 3.1 Pro) for
02/18, `mm` (Claude Code against MiniMax-M3) for the rest. All three launch with
permission prompts disabled, because a blocked edit in an unattended run just
hangs. Logs land in `.agents/logs/` (gitignored).

**Task 07 is the routing calibration point.** It is small and easy to judge.
Check it before committing to MiniMax for the other twelve.
