+# V145 + V146 - Admin sessions_sources KPI card (backend + render) - 2026-04-22
+
+## Objectif Yacine "GO FINI TOUT SANS T'ARRÊTER"
+
+Après V144 (session split + ambre-deps cache), ajouter **observabilité 
+real-time** au top panel admin dashboard. Yacine doit voir en un coup 
+d'œil la distribution par source sans ouvrir Sessions tab.
+
+## V145 — Backend channel sessions_sources ✅
+
+### Ajout
+- **Helper c_wevia()** : équivalent c204/c95 pour COUNT sur wevia_db
+- **Nouveau channel** `sessions_sources` dans `"channels"` array API response
+
+```php
+"sessions_sources" => [
+    "label"=>"Sources Sessions",
+    "icon"=>"📊",
+    "color"=>"#34d399",
+    "widget" => c_wevia("SELECT COUNT(*) FROM public.conversations WHERE source='widget'"),
+    "wevia_master" => c_wevia("... WHERE source='wevia-master'"),
+    "chatbot_api" => c_wevia("... WHERE source='wevia-chatbot-api'"),
+    "form_inline" => c_wevia("... WHERE source='form-inline'"),
+    "bots" => c_wevia("... WHERE session_id LIKE 'default-bot-%'"),
+    "legacy_null" => c_wevia("... WHERE source IS NULL"),
+    "total" => c_wevia("SELECT COUNT(*) FROM public.conversations"),
+    "today" => c_wevia("... WHERE created_at::date=CURRENT_DATE"),
+    "last_7d" => c_wevia("... WHERE created_at > NOW() - INTERVAL '7 days'"),
+],
+```
+
+### Valeurs observées (snapshot V145)
+```json
+{
+  "widget": 3272,
+  "wevia_master": 23+,
+  "chatbot_api": 0,
+  "form_inline": 3+,
+  "bots": 2481 (default-bot-% 29 buckets),
+  "legacy_null": 607,
+  "total": 6386
+}
+```
+
+### Diff admin.php
+Size 84463 → 85770 bytes (+1307 bytes pour helper + query channel).
+
+## V146 — Frontend render card ✅
+
+### Ajout dans renderChannels()
+
+**Order array étendu** :
+```javascript
+// V145:
+const order = ['chatbot_site','forms','leads','knowledge','wevia_master'];
+// V146:
+const order = ['chatbot_site','forms','leads','knowledge','wevia_master','sessions_sources'];
+```
+
+**New render branch** :
+```javascript
+else if (k==='sessions_sources') {
+    main = c.total;
+    sub = `${fmt(c.widget||0)} widget · ${fmt(c.bots||0)} bots`;
+    stats = 3 colored sub-cards:
+      🟢 Widget (emerald #34d399)
+      🟠 Master (orange #fb923c)
+      🩷 Forms (pink #f472b6)
+}
+```
+
+Chaque stat sub-card a son propre style.color inline pour visualisation 
+distincte au glance.
+
+### UX Premium doctrine 60
+- Icônes emoji contextuels (🟢🟠🩷)
+- Couleurs cohérentes avec filter dropdown V139-V142
+- Hover tooltips via `title="..."` attributs
+- Font weight + colors typographic hierarchy
