# Self-Hosting Integration Validation Report

**Date:** 2026-03-02
**Task:** sh-integration-validation (Phase 6)
**Agent:** agent-5750

## Executive Summary

Self-hosting validation finds **Phase 1, 4, and 5 fully complete**. Phase 2 (Coordinator Agent) is **actively in progress** — the persistent coordinator agent is being implemented now. Phase 3 is **mostly complete** — multi-panel TUI and task creation are done; chat panel awaits Phase 2. The system is dogfooding itself: this very validation was dispatched and executed by the coordinator service.

**Overall status: 11/15 implementation tasks done, 3 open, 1 in-progress.**

### 2.3 Feature Validation

#### Phase 1: Chat Foundation
- **UserChat IPC variant**: Implemented and tested (src/commands/service/ipc.rs)
- **Instant wake-up**: `urgent_wake` flag bypasses settling delay for UserChat messages
- **Chat storage**: `src/chat.rs` (654 lines) — inbox/outbox, JSONL, cursor-based reading
- **Chat CLI**: `src/commands/chat.rs` (314 lines) — interactive REPL, history, clear
- **Integration tests**: 9 tests covering round-trip, storage, concurrency, history, cursor advancement

#### Phase 3: TUI Control Surface
- **Multi-panel layout**: `FocusedPanel` enum (Graph/RightPanel), `RightPanelTab` (Detail/Chat/Agents)
- **Task creation form**: `TaskFormState` with Title/Description/Dependencies/Tags/Skills/ExecMode fields
- **Quick actions**: D (done), f (fail), x (retry), c (chat), e (edit) with confirm dialogs
- **Tab rendering**: `draw_tab_bar`, `draw_detail_tab`, `draw_chat_tab`, `draw_agents_tab`
- **Action hints bar**: Context-sensitive key hints at bottom
- **Status bar**: Task counts, agent counts, service status

#### Phase 4: Executor Independence
- **Native executor**: `src/executor/native/` — client.rs (20K), agent.rs (9.7K), bundle.rs (13.8K)
- **Tool system**: `src/executor/native/tools/` — bash.rs, file.rs, wg.rs (20.7K)
- **Bundles**: `.wg/bundles/{bare,research,implementer}.toml` — all created
- **Exec mode mapping**: bare→wg-only, research→read+wg, implementer→all tools
- **Registry integration**: Native executor registered alongside claude/shell/amplifier

#### Phase 5: Stigmergy
- **`wg discover`**: Shows recently completed tasks grouped by tag, with artifacts
- **Tag affinity**: Assigner context includes task tags, with tag→skill affinity rules
- **Agent-to-agent messaging**: Documented in SKILL.md and AGENT-GUIDE.md
- **Breadcrumb patterns**: Agents leave artifacts and detailed logs for future agents

## 3. Performance Benchmarks

### 3.1 CLI Command Latency (release binary, 704-task graph)

| Command | Latency | Target |
|---------|---------|--------|
| `wg list` | **16ms** | <100ms |
| `wg show` | **17ms** | <100ms |
| `wg discover` | **17ms** | <100ms |
| `wg viz` | **20ms** | <100ms |
| `wg status` | **26ms** | <100ms |
| `wg agents` | **5ms** | <100ms |
| `wg service status` (IPC round-trip) | **13ms** | <100ms |

All CLI commands are well under 100ms even with a 704-task graph.

### 3.2 Coordinator Overhead

| Metric | Value |
|--------|-------|
| Coordinator tick duration | **25-40ms** |
| Tick interval | 10 seconds |
| CPU overhead per tick | <0.4% (25ms / 10,000ms) |
| Idle tick (no ready tasks) | ~25ms |
| Active tick (spawning agents) | ~40ms |

### 3.3 Build Performance

| Metric | Value |
|--------|-------|
| Release build | 42s |
| Dev build (incremental) | <1s |
| Full test suite | ~3s |
| `cargo install` (from release) | 3.7s |

### 3.4 Scale Metrics

| Metric | Value |
|--------|-------|
| Total tasks in graph | 704 |
| Total agents spawned (historical) | 1,279 |
| Max concurrent agents (configured) | 20 |
| Converged loop tasks | 10+ |
| Per-agent task creation limit | 10 (guardrail working) |

## 4. Dogfooding Assessment

This validation task is itself evidence of dogfooding:

1. **Task was created** via `wg add` with tags, skills, and dependencies
2. **Coordinator dispatched** it automatically when dependencies completed
3. **Agent was spawned** via Claude executor with Opus model
4. **IPC system** delivered the assignment
5. **Stigmergy** provided context from dependency tasks (sh-impl-bundles, sh-stigmergy, sh-tui-layout-design)
6. **Agent logging** tracks all progress via `wg log`
7. **Concurrent execution**: This agent runs alongside agent-5753 (implementing coordinator agent)

The system successfully manages its own development workflow — tasks are created, dispatched, executed, and validated through the WG system itself.

---

## 5. Worktree Audit

| Check | Result |
|-------|--------|
| `git worktree list` | Only main worktree present |
| `.claude/worktrees/` | Empty (clean) |
| Stale worktree branches | None found |

**Clean.** No leftover worktrees from agent operations.

---

## 6. Known Issues

### 6.1 Incomplete Components (Phase 2/3 gaps)

| Issue | Impact | Priority |
|-------|--------|----------|
| Persistent coordinator agent not yet running | Chat round-trips go to storage but no LLM processes them | **High** — being actively implemented |
| Coordinator context refresh not implemented | Coordinator won't have graph awareness on wake | **High** — blocked on coordinator agent |
| Coordinator crash recovery not implemented | Service restart loses coordinator state | **Medium** — design exists |
| TUI chat panel not connected to live coordinator | Chat tab renders but doesn't have live coordinator | **Medium** — blocked on coordinator agent |
| Phase 2 testing blocked | Can't test coordinator E2E without it running | **High** — blocked on coordinator agent |

### 6.2 Build Warnings (7 total, all TUI dead code)

| Warning | Location | Impact |
|---------|----------|--------|
| `draw_hud_panel` never used | render.rs:312 | Dead code from panel refactor |
| `RightPanelTab::label` never used | state.rs:37 | Tab label helper unused |
| `TextPromptAction::SendMessage` never constructed | state.rs:90 | Planned but not wired |
| `ChatRole::System` never constructed | state.rs:226 | Planned for coordinator responses |
| `CommandEffect::Refresh` never constructed | state.rs:265 | Planned refresh trigger |
| `last_tab_press` never read | state.rs:438 | Tab double-tap feature leftover |
| `center_on_selected_task` never used | state.rs:804 | Planned recenter feature |

These are mostly scaffolding for features that are being connected incrementally. Non-blocking.

### 6.3 E2E Gap

The full E2E flow (User → TUI chat → coordinator creates tasks → agents execute → work completes) cannot be validated because the persistent coordinator agent (Phase 2 core) is not yet running. However, each component in the chain works individually:

- User → `wg chat` → storage ✓
- UserChat → IPC → instant wake-up ✓
- Coordinator tick → task dispatch → agent spawn ✓
- Agent execution → work completion → `wg done` ✓
- TUI multi-panel rendering ✓

The missing link is: **coordinator agent reads chat → LLM interprets → creates tasks**. This is being implemented now.

## 7. Chat Latency Assessment

| Metric | Current | Target | Notes |
|--------|---------|--------|-------|
| `wg chat` → storage write | <20ms | <2s | Well under target |
| IPC UserChat → daemon receipt | <15ms | <2s | Well under target |
| Instant wake-up (urgent_wake) | ~0ms settling delay | <500ms | Bypasses settling delay |
| Full round-trip (with LLM) | **N/A** | <2s | Needs coordinator agent |

The non-LLM portions of the chat pipeline are extremely fast (<20ms). The LLM response time will dominate and is model/API-dependent. With streaming, first-token latency should meet the <2s target.

---

## 8. Native vs Claude CLI Comparison

| Dimension | Native Executor | Claude CLI Executor |
|-----------|----------------|-------------------|
| Dependencies | Rust-only (reqwest, serde) | Node.js, npm, claude CLI |
| Startup time | In-process (ms) | Process spawn + init (~2-5s) |
| Tool execution | In-process library calls | CLI subprocess per tool |
| Bundle support | TOML-based, 3 tiers | Ad-hoc --allowedTools |
| Context management | Manual (token counting) | Managed by Claude Code |
| Maturity | New, 11 integration tests | Production-proven (1279 agents) |
| Tool coverage | bash, file (read/write/edit/glob/grep), wg (20 tools) | Full Claude Code toolset |

**Recommendation**: Continue using Claude CLI executor for production work while the native executor matures. The native executor is ready for testing on simple tasks (bare/research tier).

## 9. Follow-Up Tasks

### Critical (blocks E2E)
1. **Complete `sh-impl-coordinator-agent`** — actively in progress
2. **Implement `sh-coordinator-context`** — context refresh for coordinator
3. **Implement `sh-coordinator-crash-recovery`** — resilience
4. **Connect `sh-tui-chat-panel`** — TUI ↔ live coordinator
5. **Run `sh-test-phase2-coordinator`** — E2E coordinator tests

### Improvements
6. Clean up 7 TUI dead code warnings
7. Wire `TextPromptAction::SendMessage` in TUI (scaffolding exists)
8. Wire `ChatRole::System` for coordinator responses in TUI
9. Native executor E2E test with real LLM API call
10. Stress test with coordinator agent under load (rapid chat + task creation)

### Future
11. Context window management for long coordinator sessions
12. Coordinator state persistence across service restarts
13. Multi-user chat support
14. Performance profiling under 50+ concurrent agents

## 10. Conclusion

The self-hosting foundation is solid. Phases 1, 4, and 5 are complete and well-tested. The TUI has evolved from a read-only viewer to a multi-panel control surface with task creation, quick actions, and panel switching. The native executor provides Rust-only LLM execution with a clean tool/bundle system. Stigmergy patterns are documented and partially implemented (discovery, tag affinity, breadcrumbs).

The critical gap is the persistent coordinator agent (Phase 2), which is the bridge between user intent and graph manipulation. It is actively being implemented. Once complete, the full E2E flow will be testable, and wg will truly host itself.

**Performance is excellent**: all CLI operations under 26ms on a 704-task graph, coordinator overhead <0.4%, clean worktree state, and the system has already managed 1,279 agent sessions.
