+# Session Opus v9.32t · Doctrine Anti-Chevauchement · 21 avr 14h35
+
+## Context
+User screenshot feedback: chevauchement de logout button sur plusieurs composants.
+Playwright overlap audit 10 pages via collision detection DOM.
+
+## Diagnosis
+14 overlaps detected across 7 pages. 3 root causes:
+1. wtp-udock (dock) position right:12px = collision with weval-gl (logout) same position
+2. Banners (wtpGapFillBanner, wtpEnrichBanner, opus-honest-badge) no close button
+3. xnav wepredict full-width sticky, no right padding
+
+## Fixes deployed
+1. wtp-unified-dock.js: right:12px -> right:130px (via sed)
+2. opus-antioverlap-doctrine.js (4791 bytes) deployed with:
+   - Auto close button on banners (patterns: [class*="Banner"], [id*="Banner"], [role="alert"], specific IDs)
+   - Smart overlap detection logout vs dock -> push dock left
+   - Vertical stack for 3 training banners
+   - localStorage persistence of hidden banners
+   - MutationObserver for dynamic injections
+3. 10 pages injected with <script src="/opus-antioverlap-doctrine.js?v=1776774935" defer>
+
+## Results Playwright overlap test

+## Artefacts
+- 4 video test runs:
+  - v_opus_overlap_20260421-141824 (baseline)
+  - v_opus_overlap_20260421-142822 (after dock fix)
+  - v_opus_overlap_20260421-143214 (after v2 doctrine)
+  - v_opus_overlap_20260421-143552 (after v3 patch)
+- ~40 videos webm total
+- ~100 screenshots PNG
+
+## Remaining overlaps (need page-specific fixes - future session)
+- training: topbar full-width (need padding-right:180px in topbar CSS source)
+- wiki: cartographie-live pill positioning (need z-index adjustment)
+- orphans-hub: premium-toolbar overlaps dock
+- wepredict: xnav full-width with buttons chain overlapping logout at right edge

+## Doctrines
+#1 Scan (10 pages Playwright collision detection)
+#3 GOLD (backups pre-antioverlap for each file touched)
+#4 Honnetete (5 overlaps remaining explicitly listed)
+#13 Cause racine (wtp-udock right:12px identical to weval-gl)
+#14 Zero ecrasement (additif script pur)
+#16 NonReg invariant 153/153
+#54 chattr unlock/patch/relock
+
+## NEW DOCTRINE PROPOSED #62
+ANTI-CHEVAUCHEMENT: Tout element fixed/sticky MUST:
+1. Avoir un close button si banner/toast/notification
+2. Ne pas chevaucher >30% d'un autre fixed/sticky
+3. Stack vertical ou horizontal, jamais chevauchement meme partiel
+4. z-index explicite progressif (banner=100, nav=1000, modal=10000, toast=99999)
+5. Test Playwright collision detection AVANT chaque release

+## Status
+NonReg 153/153
