+# Phase 08: Content & Cocon Sémantique — Verification Report
+
+**Phase Goal:** 2 articles seed Hytale (FR+EN, draft:false, liens inline /hytale), section "Articles récents" sur /hytale filtrée tag=hytale, cocon sémantique bidirectionnel.
+**Verified:** 2026-04-22
+**Status:** passed
+**Re-verification:** No — initial verification
+
+## Goal Achievement
+
+### Observable Truths
+
+| # | Truth | Status | Evidence |
+|---|-------|--------|----------|
+| 1 | 4 markdown articles exist (FR+EN × 2), `draft: false`, tag `hytale`, ≥800 words | VERIFIED | wc -w: 1049, 970, 1148, 1009; frontmatter confirms `tags: ["hytale", ...]` and `draft: false` in all 4 |
+| 2 | FR articles contain inline link `](/hytale)` | VERIFIED | grep: 2 occurrences per FR file (4 total) |
+| 3 | EN articles contain inline link `](/en/hytale)` | VERIFIED | grep: 2 occurrences per EN file (4 total) |
+| 4 | `HytaleRecentArticles.vue` uses literal queryCollection branches + JS tag filter + slice(0,2) + v-if | VERIFIED | Component reads: `queryCollection('blog_fr')` / `queryCollection('blog_en')` literals (L13,17); `a.tags.includes('hytale')` (L28); `.slice(0, 2)` (L28); `v-if="articles.length"` (L34) |
+| 5 | `app/pages/hytale.vue` mounts `<HytaleRecentArticles`  | VERIFIED | grep: line 38 `<HytaleRecentArticles />` |
+| 6 | i18n keys `hytale.recentArticles.{title,subtitle,viewAll}` present in fr.json + en.json | VERIFIED | fr.json L556-560 and en.json L556-560 all 3 keys present |
+
+**Bonus:** `pnpm typecheck` exit 0 (clean).
+
+### Required Artifacts
+
+| Artifact | Expected | Status | Details |
+|----------|----------|--------|---------|
+| `content/fr/blog/how-to-build-your-first-hytale-plugin.md` | Tutorial FR, draft:false, tag hytale, ≥800w, link /hytale | VERIFIED | 1049 words, frontmatter correct, 2× `](/hytale)` |
+| `content/en/blog/how-to-build-your-first-hytale-plugin.md` | Tutorial EN, draft:false, tag hytale, ≥800w, link /en/hytale | VERIFIED | 970 words, frontmatter correct, 2× `](/en/hytale)` |
+| `content/fr/blog/hytale-plugin-development-2026.md` | Industry FR, draft:false, tag hytale, ≥800w, link /hytale | VERIFIED | 1148 words, frontmatter correct, 2× `](/hytale)` |
+| `content/en/blog/hytale-plugin-development-2026.md` | Industry EN, draft:false, tag hytale, ≥800w, link /en/hytale | VERIFIED | 1009 words, frontmatter correct, 2× `](/en/hytale)` |
+| `app/components/HytaleRecentArticles.vue` | Literal queryCollection + JS filter hytale + slice(0,2) + v-if | VERIFIED | All patterns present |
+| `app/pages/hytale.vue` | Mounts `<HytaleRecentArticles />` | VERIFIED | Line 38 |
+| `i18n/locales/fr.json` | hytale.recentArticles.{title,subtitle,viewAll} | VERIFIED | L556-560 |
+| `i18n/locales/en.json` | hytale.recentArticles.{title,subtitle,viewAll} | VERIFIED | L556-560 |
+
+### Key Link Verification
+
+| From | To | Via | Status |
+|------|-----|-----|--------|
+| Articles FR blog → /hytale | Service page | Markdown inline link `](/hytale)` | WIRED (2× per article) |
+| Articles EN blog → /en/hytale | Service page | Markdown inline link `](/en/hytale)` | WIRED (2× per article) |
+| /hytale page → recent blog articles | Cocon retour | `<HytaleRecentArticles />` querying `blog_fr`/`blog_en` filtered tag=hytale | WIRED |
+| HytaleRecentArticles → BlogCard rendering | Data flow | `queryCollection(...).where(draft,=,false).order(date,DESC).all()` + JS filter on tags + slice(0,2) | WIRED — data flows from @nuxt/content collection to render |
+
+### Data-Flow Trace (Level 4)
+
+| Artifact | Data Variable | Source | Produces Real Data | Status |
+|----------|--------------|--------|--------------------|--------|
+| HytaleRecentArticles.vue | `articles` computed | `useAsyncData` → `queryCollection('blog_fr'/'blog_en')` (real @nuxt/content SQLite collections populated by the 4 articles above) | Yes — 2 hytale-tagged articles per locale exist in content/, draft:false | FLOWING |
+
+### Requirements Coverage
+
+| Requirement | Source Plan | Description | Status | Evidence |
+|-------------|-------------|-------------|--------|----------|
+| BLOG-07 | 08-01, 08-02 | Seed content Hytale publié (≥2 articles FR+EN, draft:false, tag hytale) | SATISFIED | 4 articles live, frontmatter compliant, word counts ≥800 |
+| SEO-14 | 08-01, 08-02, 08-03 | Cocon sémantique bidirectionnel blog↔service Hytale | SATISFIED | Inline links from articles → /hytale (FR) & /en/hytale (EN); HytaleRecentArticles section back from /hytale → blog articles; tag filter `hytale` enforces topical relevance |
+
+### Anti-Patterns Found
+
+None. Component correctly avoids known pitfalls documented in comments:
+- D-03: literal `queryCollection` branches (not variable) for Vite extractor
+- D-11: JS post-query filter instead of unreliable SQLite LIKE on JSON array
+- T-08-01: `Array.isArray` guard before `.includes` for schema-broken frontmatter safety
+
+### Behavioral Spot-Checks
+
+| Behavior | Command | Result | Status |
+|----------|---------|--------|--------|
+| TypeScript compiles cleanly | `pnpm typecheck` | Exit 0, no errors | PASS |
+
+### Human Verification Required
+
+None — all checks verifiable via static analysis / grep / typecheck.
+
+### Gaps Summary
+
+No gaps. Phase 08 fully achieves its goal: cocon sémantique bidirectionnel complete, 4 seed articles published with proper frontmatter, /hytale page loops back to recent hytale-tagged articles via a wired component that correctly queries @nuxt/content with known-pitfall-safe patterns.
