 - [ ] **Multi-machine real-world testing** -- Test bterminal-relay with 2 machines.
 - [ ] **Multi-machine TLS/certificate pinning** -- TLS support for bterminal-relay + certificate pinning in RemoteManager.
 - [ ] **Agent Teams real-world testing** -- Env var whitelist fix done. 3 test sessions ran ($1.10, $0.69, $1.70) but model didn't spawn subagents — needs complex multi-part prompts to trigger delegation. Test with CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1.
-- [ ] **SOLID Phase 2 — agent-dispatcher.ts** -- God module (496 lines, 9 concerns). Extract event routing, session persistence, subagent routing into separate modules.
-- [ ] **SOLID Phase 2 — session.rs** -- Mixed concerns (1008 lines, 8 tables). Split by table lifecycle.
 - [ ] **SOLID Phase 3 — Primitive obsession** -- SessionId, ProjectId, FilePath as raw strings across 15+ files. Introduce value objects.
 
 ## Completed
 
+- [x] **SOLID Phase 2 — agent-dispatcher.ts split** -- 496→260 lines. Extracted 4 modules: utils/worktree-detection.ts (pure function, 5 tests), utils/session-persistence.ts (session maps + persist), utils/auto-anchoring.ts (compaction anchor), utils/subagent-router.ts (spawn + route). Dispatcher is thin coordinator. 286 vitest + 49 cargo tests. | Done: 2026-03-11
+- [x] **SOLID Phase 2 — session.rs split** -- 1008→7 sub-modules under session/ directory (mod.rs, sessions.rs, layout.rs, settings.rs, ssh.rs, agents.rs, metrics.rs, anchors.rs). pub(in crate::session) conn visibility. 21 new cargo tests. 49 cargo tests total. | Done: 2026-03-11
 - [x] **SOLID Phase 1 Refactoring** -- Extracted AttentionScorer pure function (14 tests), shared str()/num() type guards, split lib.rs (976→170 lines, 11 command modules). 286 vitest + 49 cargo tests. | Done: 2026-03-11
 - [x] **Configurable stall threshold** -- Per-project range slider (5–60 min, step 5) in SettingsTab. `stallThresholdMin` in ProjectConfig, `setStallThreshold()` API in health store, ProjectBox $effect sync. Adaptive suggestions deferred (needs 50+ sessions in session_metrics). | Done: 2026-03-11
 - [x] **Register Memora adapter** -- MemoraAdapter (memora-bridge.ts) implements MemoryAdapter, reads ~/.local/share/memora/memories.db via Rust memora.rs (read-only SQLite, FTS5 search). 4 Tauri commands, 16 vitest + 7 cargo tests. 272 vitest + 49 cargo total. | Done: 2026-03-11

 - [x] **S-2 — Session Anchors + Configurable Budget** -- Preserves important turns through compaction chains. Auto-anchors first 3 turns (observation-masked — reasoning preserved in full per research). Configurable budget via AnchorBudgetScale slider (Small=2K, Medium=6K, Large=12K, Full=20K) in SettingsTab per-project. Manual pin, promote/demote in ContextTab. Re-injection via system_prompt. 219 vitest + 42 cargo tests. | Done: 2026-03-11
 - [x] **Agent provider adapter pattern** -- Multi-provider support (Claude, Codex, Ollama) via 3-phase adapter pattern. Core abstraction, Settings UI, Sidecar routing. 5 new files, 4 renames, 20+ modified. 202 vitest + 42 cargo tests. | Done: 2026-03-11
