# Phase 4: Installation & Fleet Status Verification Report

**Phase Goal:** Users can install OpenClaw on Ubuntu hosts and view fleet status
**Verified:** 2026-03-21T21:45:00Z
**Status:** passed
**Re-verification:** No — initial verification

## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | User runs `clm install` and flows through: pick claw → pick host → validate compatibility → install | ✓ VERIFIED | CLI command exists with interactive prompts (_select_claw, _select_host) and flag overrides (--claw, --host). Tests verify both flows. Compatibility checked before installation (line 118 install.py). |
| 2 | Installation validates compatibility before proceeding and fails fast if host is incompatible | ✓ VERIFIED | check_compatibility called at line 118 in install.py. Raises InstallationError with reasons if incompatible (lines 120-122). Tests verify incompatibility detection. |
| 3 | User sees real-time progress during installation (base setup, dependencies, claw installation) | ✓ VERIFIED | Rich Progress spinner implemented with on_event callback. Stages: validate, base, claw. Progress updated via callback at lines 278-297 in cli/install.py. Tests verify event streaming. |
| 4 | Installation fails fast with clear error messages if any step fails | ✓ VERIFIED | InstallationError raised at validation (lines 108, 113, 120-122, 148), base playbook failure (line 187), claw playbook failure (line 211). Error messages include specific reasons. Tests verify all error paths. |
| 5 | User runs `clm status` and sees all hosts with their claw instances, agents, and status | ✓ VERIFIED | Status command groups by claw type (D-12), shows host/version/user/status/installed_at. Live health checks performed via check_claw_health (line 75 status.py). Tests verify display and filtering. |

**Score:** 5/5 truths verified

**Coverage:** 5/5 requirements satisfied (100%)

### Anti-Patterns Found

No anti-patterns detected.

**Scan results:**
- No TODO/FIXME/XXX/HACK/PLACEHOLDER comments in any module
- No empty implementations (return null, return {}, return [])
- No hardcoded empty data flowing to user-visible output
- No console.log-only implementations
- All data structures properly initialized and populated
- All functions have substantive implementations

### Human Verification Required

#### 1. End-to-End Installation Test

**Test:**
1. Set up Ubuntu 24.04 host with xclm user and passwordless sudo
2. Run `clm host add` to register host with SSH key
3. Run `clm install --claw openclaw --host <hostname>`
4. Verify installation completes successfully
5. SSH to host and verify:
   - opc-<hostname> user exists
   - /home/opc-<hostname>/openclaw directory exists
   - npm dependencies installed
   - Node.js 20 installed
   - build-essential installed

**Expected:** Installation completes without errors. All components installed correctly. User can start OpenClaw.

**Why human:** Requires actual Ubuntu host with network access. Ansible playbooks execute real system changes. Cannot be fully mocked.

#### 2. Fleet Status Live Health Check

**Test:**
1. Install OpenClaw on host (per test 1)
2. Start OpenClaw process as opc-<hostname> user
3. Run `clm status`
4. Verify status shows "running" in green
5. Stop OpenClaw process
6. Run `clm status` again
7. Verify status shows "stopped" in red

**Expected:** Status accurately reflects live process state. SSH checks execute without timeout. Display updates correctly.

**Why human:** Requires running OpenClaw process. Live SSH execution to remote host. Real-time process state detection.

#### 3. Installation Error Handling

**Test:**
1. Attempt to install OpenClaw on incompatible host (e.g., 32-bit arch, Ubuntu 22.04, insufficient memory)
2. Verify installation rejected with clear compatibility reasons before any playbook runs
3. Attempt installation with missing SSH key
4. Verify clear error message about missing key
5. Simulate playbook failure (e.g., network timeout during npm install)
6. Verify failed state recorded in host record
7. Run `clm status` and verify "install failed" shown in red

**Expected:** All error paths provide clear, actionable messages. No partial installations leave system in broken state. Status correctly shows failed installations.

**Why human:** Requires testing edge cases and failure scenarios. Network conditions, permission issues, and system state variations difficult to fully simulate.

### Gaps Summary

No gaps found. All must-haves verified, all requirements satisfied, all artifacts substantive and wired.
