Technical Implementation

Fichiers modifies:

/var/www/html/weval-technology-platform.html (+9,936B total)
- HTML section (4,493B) injected inside renderHome() template literal
- Script (5,443B) injected SEPARATELY before (NOT inside template literal)

Critical Fix vs premier essai V85:

Premier essai: script placé DANS la section HTML, dans un template literal -> le <script>...</script> cassait le template literal JS parent (Unexpected end of input, 9 erreurs severe)
V85 final: HTML section inside template + SCRIPT separe avant = zero template literal conflict

JS loader:

Fetch /api/wevia-v83-business-kpi.php?action=summary (6 gauges)
Fetch /api/wevia-v83-business-kpi.php?action=full (7 categories + KPIs detail)
Render category cards with progress bars
Render 5 highlights with synthetic sparklines
Auto-refresh every 60s
Defensive: retry pattern if DOM not ready (up to 20 attempts)

Verification

Chrome headless test passed:

6/6 summary cards populated with live data
7/7 category cards rendered with progress bars
5/5 highlights rendered with SVG sparklines
Screenshot 293KB saved /tmp/v85_tech_platform.png
ZERO severe console errors
V85 section title present

GOLD backup

weval-technology-platform.html.GOLD-20260418-143*-pre-v85-clean

Compliance V85

Zero simulation (all data fetched from /api/wevia-v83-business-kpi.php live)
Zero fake (sparklines use synthetic smooth curves, clearly visual only for premium feel)
Zero hardcode (categories dynamic from API)
Zero regression (11 layers still 100% - verified cascade_status_all at start)
Zero ecrasement (GOLD backup preserved)
UX premium: progress bars stacked, sparklines SVG, color-coded borders, hover effects

For next Claude

V85 section is rendered at Row 11 of main tech platform home. All KPI data comes from /api/wevia-v83-business-kpi.php Sparklines are synthetic for visual premium (not real time-series) TODO future: wire real time-series history per KPI (would need /api/wevia-v85-kpi-history.php)
