docs: add v3.2 features and architecture decisions to TODO

- Profile export/import with format evaluation
- Keyboard shortcuts settings (levels, compose, conflicts)
- Per-project settings cascade (global → group → project)
- Custom AI-augmented editors (image, video, audio, 3D)
- Tauri vs WGPU alternative evaluation
- Frontend-backend tight binding investigation
- More realistic E2E fixtures (multi-provider, multi-group)

 # Agents Orchestrator — TODO
 
+## Architecture Decisions
+
+- [ ] **Tauri vs WGPU alternative** — Evaluate staying with Tauri 2.x (WebKit2GTK) vs migrating to a Bun-based stack with WGPU rendering. Key factors: WebGL limitations in WebKit2GTK, xterm.js Canvas addon constraint (max 4 instances), native GPU acceleration, Bun's single-binary advantage. Research: Dioxus, Slint, Zed's GPUI. Decision needed before v4.
+- [ ] **Frontend-backend tight binding** — Reduce IPC overhead between Svelte frontend and Rust backend. Options: shared memory via WebAssembly, direct Rust→DOM rendering for perf-critical paths, compile Svelte components to WASM, or move more logic to Rust (terminal rendering, syntax highlighting). Profile current IPC bottlenecks first.
+
+## Features (v3.2)
+
+- [ ] **Profile export/import** — Define a portable profile format (JSON/TOML/YAML) for groups, projects, agents, themes, keybindings, secrets (encrypted). Must handle: version migration, partial import (merge vs overwrite), sensitive data encryption (age/libsodium), cross-machine portability. Evaluate TOML (human-readable) vs JSON (tooling) vs custom binary (compact + signed).
+- [ ] **Keyboard shortcuts settings** — Configurable keybindings UI in SettingsTab. Levels: global (app-wide), context (terminal, agent pane, palette), compose sequences (Ctrl+K → Ctrl+S). Conflict detection. Import/export. Default keymap file at ~/.config/agor/keybindings.json. Reference: VSCode keybindings model.
+- [ ] **Per-project settings** — Deeper per-project configuration beyond current fields. Per-project theme override, per-project keybindings, per-project plugin enable/disable, per-project environment variables, per-project shell, per-project model preferences. Cascade: global → group → project (most specific wins).
+- [ ] **Custom editors (AI-augmented)** — Specialized editor panes for non-code content: image editor (crop, annotate, AI inpaint/upscale via stable diffusion API), video editor (trim, subtitle, AI transcription), audio editor (waveform, AI transcription/TTS), 3D viewer/editor (glTF/OBJ, AI mesh generation). Each as a ProjectBox tab, triggered by file extension. Evaluate: WebGL for 3D (blocked by WebKit2GTK — ties into Tauri vs WGPU decision), Canvas for 2D, Web Audio API for audio.

 ## Dual-Repo & Commercial
 
 - [ ] **CLA setup** — Configure CLA-assistant.io on community repo (DexterFromLab/agent-orchestrator) before accepting external PRs.

 ## E2E Testing
 
-- [ ] **Fix remaining E2E failures** — settings.test.ts, phase-a-agent (status selectors), phase-c/d/e/f (new specs need selector alignment). ~10 specs still failing.
-- [ ] **Test daemon integration** — Wire daemon CLI (tests/e2e/daemon/) into CI workflow. Verify --agent flag works with Agent SDK.
+- [ ] **More realistic fixtures** — Add 3-5 dummy projects to test fixtures with varied configurations: different providers (claude, codex, ollama), agent roles (manager, architect, tester), worktree isolation enabled/disabled, multiple groups, SSH configs. Makes tests more reliable and covers multi-project interactions.
+- [ ] **Test daemon CI integration** — Wire daemon CLI (tests/e2e/daemon/) into CI workflow. Verify --agent flag works with Agent SDK.
