+# Task 15f — Restore the content 15d dropped from /full-guide/
+
+**Agent**: `page-migrator` · **Model**: Codex **Depends on**: 15d **Blocks**:
+19, 20 **Worktree**: `.agents/scripts/worktree.sh start 15f full-guide-restore`
+
+## Goal
+
+`/full-guide/` is missing about a fifth of the page. Put it back, in the right
+place, bilingual where the legacy page is bilingual.
+
+Task 15d assembled the page and passed every check. It also dropped 87 rendered
+text spans. One of them — the `.chapter-route` section, the only route out of
+the guide to the summary, models, agents and skills chapters — has already been
+restored (`c2b35d5`). The remaining 86 are your task.
+
+Nothing caught this. `scripts/verify.mjs` reads `full-guide/index.html`, the
+legacy file, which still has every one of these sections. The gate was green the
+whole time. Task 19 is blocked on you: it re-pointed its assertions at `dist/`
+and they now fail, correctly, on exactly this content.
+
+## How to see the gap
+
+```
+pnpm run build
+node .agents/scripts/rendered-text-diff.mjs full-guide
+```
+
+It walks the live DOM of both pages and prints the text the legacy page paints
+and the Astro page does not. It skips hidden nodes, so the Portuguese half of
+each bilingual pair does not register as a difference, and it waits for the
+islands to hydrate, so the tab panels' injected copy counts as present.
+
+**This script reaching zero is the task.** Do not edit it to make it pass.
+
+## What is missing
+
+Whole blocks, not scattered strings. By CSS class, present in
+`full-guide/index.html` and absent from `dist/full-guide/index.html`:
+
+`verify-intro`, `verify-cta`, `verify-cta-grid`, `verify-card`,
+`verify-card-source`, `verify-antipatterns`, `ap-grid`, `comparison-strip`,
+`exercise-brief`, `builder-intro`, `builder-loop`, `builder-artifact`,
+`artifact-head`, `artifact-command`, `starter-link-group`, `starter-link-source`
+
+That covers, at minimum: the three-layer verification section and its code
+lines, the "four ways a green report is false" grid, the two hands-on lab cards
+with both "Clone from Gitea →" links, the exercise brief (stack / dependencies /
+files), the four-row comparison strip, and the skill-forge output package tree
+with its validate and after-real-use panels.
+
+The exact 86 spans, in document order:
+
+```
+  - default start
+  - name: review-ui · check focus, mobile, reduced motion · run verification · return evidence
+  - The skill forge
+  - Teach the decision.
+  - Keep the context
+  - light.
+  - Do not package everything you know. Capture the non-obvious choices that repeatedly improve an outcome, then prove the skill changes behavior.
+  - Observe
+  - find repeated friction
+  - Define trigger
+  - route precisely
+  - Choose anatomy
+  - only needed files
+  - Write guidance
+  - decisions, not trivia
+  - Validate
+  - test real behavior
+  - OUTPUT / SKILL PACKAGE
+  - review-ui/
+  - ├── SKILL.md
+  - ├── agents/
+  - │ └── openai.yaml
+  - ├── references/
+  - │ └── accessibility.md
+  - └── scripts/
+  - └── verify.mjs
+  - VALIDATE
+  - quick_validate.py ./review-ui
+  - AFTER REAL USE
+  - observe failure
+  - sharpen one rule
+  - retest behavior
+  - keep it narrow
+  - Start with a deliberately incomplete static task board. Run one prompt as written, reset, then run the skill-enabled version. Compare diff size, verification evidence, and unnecessary complexity.
+  - Clone from Gitea →
+  - Clone from Gitea →
+  - THE MISSING FEATURE
+  - Add All / Open / Done filters that survive reload and browser navigation.
+  - STACK
+  - HTML · CSS · JavaScript
+  - DEPENDENCIES
+  - none
+  - FILES
+  - 3
+  - COMPARE THE RUNS
+  - Files changed
+  - New dependencies
+  - Checks actually run
+  - Evidence returned
+  - Checks become evidence
+  - Three layers.
+  - Run each one alone.
+  - Run a gate on its own line, print its exit code, attach the output. The result is the deliverable.
+  - Format, lint, type-check. Fast and scoped to one file. Run on every save.
+  - pnpm lint; echo "lint=$?" pnpm typecheck; echo "typecheck=$?"
+  - pnpm test; echo "test=$?" cd services/api && go test ./...
+  - Drive the actual UI, API, or browser. Slower and flakier — only this catches mobile overflow and a missing 404.
+  - pnpm check:ui; echo "ui=$?" TURBO_FORCE=true pnpm e2e
+  - FOUR WAYS A GREEN REPORT IS FALSE
+  - 1
+  - Pipe a gate
+  - tail, grep, or head hide the real exit code — a pipeline returns the last command's status.
+  - 2
+  - Swallow a rejection
+  - A silent
+  - .catch(() => {})
+  - hides a panic, an upstream limit, or a partial failure.
+  - 3
+  - Trust the cache
+  - Turbo caches results. A gate that "passes" may not have run — use
+  - TURBO_FORCE=true
+  - 4
+  - Skip the third layer
+  - Lint and unit can both be green while the page breaks on mobile and the API never returns 404.
+  - RUN IT YOURSELF · two labs, under 10 minutes each
+  - Path A · verification lab
+  - Fill the four-row comparison strip on the starter. Run A naively, Run B with
+  - $gate-discipline
+  - and
+  - $webapp-testing
+  - Clone ↗
+  - git.marcospaulo.dev.br/.../src/branch/pages/hands-on/starter
+  - Path B · rules lab
+  - Toggle every rule off, run the prompt. Toggle every rule on, run it again. Compare diff size, gate invocations, and the names of checks the agent names back.
+  - Clone ↗
+  - git.marcospaulo.dev.br/.../src/branch/pages/hands-on/rules
+```
+
+## Method
+
+1. Read the legacy source for each block out of `full-guide/index.html`. Copy
+   the strings; do not retype them. Several contain box-drawing characters
+   (`├──`, `└──`), `·` separators, and `$`-prefixed skill names.
+2. Place each block where the legacy page has it — the section order is part of
+   the argument the page is making.
+3. Bilingual pairs follow `.agents/rules/content-i18n.md`: render the fragment
+   twice, `data-language-content="en"` visible and `data-language-content="pt"`
+   hidden. **Check `translations.pt` in `app.js` before assuming a block is
+   bilingual.** Several of these are English-only on the live site —
+   `.chapter-route` was — and inventing Portuguese for them is a regression in
+   the other direction.
+4. Reuse the existing blocks in `src/components/blocks/`. If a block does not
+   exist, this is assembly work that 15d should have done and you may write the
+   markup inline in the page, as 15d did elsewhere. Do not write a new island.
+
+## Do not
+
+- Do not touch `full-guide/index.html`, `app.js`, or any other legacy file.
+- Do not weaken or delete an assertion in `scripts/verify.mjs`.
+- Do not reformat files you are not restoring content into. 15d ran prettier
+  across the whole repo on one attempt and it had to be reverted.
+
+## Done when
+
+- [ ] `node .agents/scripts/rendered-text-diff.mjs full-guide` reports 0 missing
+- [ ] Every restored bilingual block has both `en` and `pt`; every English-only
+      block is English-only in `translations.pt` too, and you say which is which
+- [ ] Section order matches the legacy page
+- [ ] `pnpm run gate` green
+
+## Attempt 1: English is exact, Portuguese is not
+
+`8f82304`, tagged `rejected/15f-attempt-1`. Keep it and continue from it — the
+English restoration is correct and complete:
+
+```
+en · legacy 432 spans · astro 432 spans · missing 0 · extra 0
+```
+
+Every block is back, in the legacy order, with no invented content. That half of
+the task is done.
+
+The Portuguese half was not checked, because the tool could not check it when
+you started. `rendered-text-diff.mjs` now takes `--pt`: it clicks the language
+toggle on both pages before reading, and it reports **both** directions — a
+string the Astro page paints and the legacy page does not is as wrong as one it
+drops. On your branch:
+
+```
+pt · legacy 431 spans · astro 431 spans · missing 27 · extra 26
+```
+
+The totals match because nothing is structurally missing. The content is English
+where the legacy page shows Portuguese.
+
+### Two separate causes — fix both
+
+**1. The blocks you restored are English-only under PT.** "Create a skill",
+"INSTALL PACK", "Hands-on", "Tiny Tasks lab", "Good prompt", both long lab
+prompts, the two `Clone from Gitea →` links and the rest of the hands-on and
+skill-forge copy. The Portuguese for these is in `translations.pt` in `app.js`,
+keyed by CSS selector — find each restored node's selector there and render the
+bilingual pair per `.agents/rules/content-i18n.md`.
+
+Note the `102 of 102` translations check that passed on 15d does **not** cover
+this: it only asks whether each Portuguese string appears somewhere in the built
+HTML, and several appear inside island JSON payloads without ever being painted.
+`--pt` is the real check.
+
+**2. Pre-existing over-translation in the hero, from 15d, not from you.** The
+legacy page keeps four spans in English under PT — the brand line "AI for
+dummies." and the "THINK" / "MAKE" labels. The Astro page translates them to "IA
+para iniciantes." and "PENSE" / "FAÇA". `translations.pt` has no entry for them,
+so English is the correct Portuguese rendering. Reconcile to legacy.
+
+### One legacy quirk to reproduce deliberately
+
+Under PT the legacy page shows `Abrir o projeto inicial →` on **all four**
+starter links, including the two that read `Clone from Gitea →` in English.
+`applyLanguage` sets the same text on every `.starter-link` match. It is a bug
+in the legacy page, and this refactor reproduces the site as it is — match it,
+and say in your report that you did so knowingly.
