-# Deployment Cleanup
+# Deployment Cleanup (MANDATORY)
 
-Before launching any app (Electrobun, Tauri, GPUI, Dioxus), always kill previous instances first.
+**ALWAYS kill previous instances before launching a new one. NO EXCEPTIONS.**
+
+## The One Command
+
+Use `scripts/launch.sh` for ALL app launches. It handles kill → build → launch atomically.
+
+If not using the script, run this EXACT sequence in a SINGLE bash command:
+
+```bash
+pkill -f "launcher|AgentOrchestrator|agor-ptyd|vite.*9760" 2>/dev/null; fuser -k 9760/tcp 2>/dev/null; sleep 2 && ./agor-pty/target/release/agor-ptyd &>/dev/null & sleep 1 && cd ui-electrobun && npx vite dev --port 9760 --host localhost &>/dev/null & sleep 3 && ./node_modules/.bin/electrobun dev &
+```
 
 ## Rules
 
-- Before `electrobun dev` or any app launch: `pkill -f "launcher\|AgentOrchestrator\|agor-ptyd" 2>/dev/null; sleep 1`
-- Before `npm run tauri dev`: kill existing tauri processes
-- Before launching GPUI/Dioxus prototypes: `pkill -f "agor-gpui\|agor-dioxus" 2>/dev/null`
-- Check for port conflicts: verify the target port is free before binding
-- Never leave orphaned daemon processes (agor-ptyd) running after testing
-- When rebuilding: kill → build → launch (in that order, never launch before kill)
+- **NEVER** launch without killing first — this causes duplicate windows
+- **NEVER** split kill and launch into separate bash calls — the `cd` between them breaks the path
+- Kill command MUST include: launcher, AgentOrchestrator, agor-ptyd, vite port 9760
+- Free port 9760 with `fuser -k` before starting Vite
+- Wait 2s after kill before launching (process cleanup time)
+- The `electrobun dev` command MUST run from `ui-electrobun/` directory
