ade-perf-boot

Patterns discovered for ADE's cold launch and main-screen surfaces. Each entry has run-traced provenance — do not delete entries without explicit user approval.

Scope

This tab covers the code paths that run before any per-tab UI is mounted, plus the project-level chrome that appears regardless of which tab is open:

• Cold launch — process spawn → main process bootstrap → renderer first paint → first interactive.
• Welcome / project picker — when no project is loaded.
• Recent projects — listing, rendering, icon resolution.
• Project open flow — project.openRepo IPC, the load + bind path.
• Remote runtime — remoteRuntime.listTargets, snapshot, connection lifecycle.
• iOS / phone pairing — pairing status, auth, etc.
• App shell chrome — sidebar, header, route transitions (the AppShell wrapping all tabs).

Use ade-autoresearch boot to run an optimization cycle against this surface.

Scenarios this tab is benchmarked against

Defined in apps/desktop/src/renderer/perf/scenarios/boot.ts:

• boot.cold-paint — measures FCP / LCP / INP during cold launch (no driving).
• boot.recent-projects — project.listRecent IPC + welcome render.
• boot.open-project — project.openRepo round-trip for perf-pass.
• boot.remote-runtime — remoteRuntime.listTargets cost.
• boot.idle-welcome — 20s idle on welcome (no project) — catches background pollers.
• boot.stress-launch — 2min idle from cold — catches startup leaks.

The "no project" scenarios should be run with --no-project so the welcome screen renders:

node scripts/run-perf-scenario.mjs boot.idle-welcome run-id --no-project
