# Task 10b — Locale-paired props on the six full-guide blocks

**Agent**: `component-builder` · **Model**: **Codex** **Depends on**: 10 ·
**Blocks**: 15d **Worktree**:
`.agents/scripts/worktree.sh start 10b bilingual-blocks`

## Why this task exists

It is not in the original plan. Tasks 07–11 built the primitives and blocks
before task 15c wrote the language contract, so every prose prop on all 19
blocks is a plain `string`. Task 15d then stopped, correctly, when it found it
could not render `/full-guide/` in both languages: the brief forbids it from
duplicating a block to get a second locale, and changing a block's interface is
component-builder work, not page-migrator work.

`/full-guide/` is one of only two pages with a language toggle (the other is
`/rules/`, which is already fully bilingual — all 23 of its Portuguese strings
reach the built page, because `RulesInteractive` reads them from
`src/content/rules/stages.json` and swaps client-side). The five remaining pages
have no toggle today and must not gain one.

## Scope

Exactly six files, all in `src/components/blocks/`:

`FleetDiagram.astro`, `HandoffTable.astro`, `PhasePanel.astro`,
`RouteTable.astro`, `SkillPackage.astro`, `WorktreeMap.astro`.

These are the six that `src/pages/full-guide.astro` uses. Do not touch the other
13 blocks, any primitive, any island, or any page.

## What to change

Every **prose** prop on those six accepts `Localized` as well as `string`:

```ts
type Localized = { en: string; pt: string };
```

- Given a `string`, render exactly what it renders today. Every existing call
  site keeps working untouched — this is additive.
- Given a `Localized`, render the fragment twice per
  `.agents/context/content-i18n.md`: `data-language-content="en"` on one and
  `"pt"` on the other, English visible, Portuguese `hidden`.

Prose only. Do not widen `href`, `id`, `code`, numeric or enum props — several
are deliberately unlocalized, and task 05b recorded which (`trees.path`,
`trees.command`, `routes.score`, `commonSkills.source`).

`FleetDiagram`'s `orchestrator.title` is rendered with `set:html` because it
carries inline `<br>`. Keep that, on both locales.

## Do not

- Do not change what a block renders for a `string` prop. A diff in the built
  output for the existing call sites means you got it wrong.
- Do not add a language toggle to any block. `LanguageToggle` is a separate
  island and the page mounts it.
- Do not edit `scripts/verify.mjs`. 42 assertions, and you are not the
  verification-engineer.
- Do not touch `src/pages/full-guide.astro`. That is 15d's file; it will pass
  the `Localized` values once you land.

## Done when

- [ ] All six blocks accept `Localized` on every prose prop and `string` still
      behaves identically
- [ ] Built output byte-identical for pages that pass only strings — check
      `dist/` before and after for the pages that use these blocks
- [ ] `pnpm run gate` green, 42 assertions intact
- [ ] Report lists, per block, which props became locale-aware and which you
      deliberately left unlocalized and why
