| --------------------------------------- | ---- | ---------------------------- | -------- | ---------------------------------------------------------------------- |
| src/clawrium/core/registry.py          | 283  | Dependency check deferred    | ℹ️ Info  | Pass statement in dependency loop - documented limitation for v1       |

**Notes:**
- The `pass` in dependency checking (lines 277-283) is a documented deferral, not a stub. The `_check_dependency_version()` helper exists (lines 179-195) but is unused because HardwareInfo doesn't include installed package versions in v1. This is noted in plan 03-03 decisions and doesn't block the phase goal.
- All other requirement types (OS, arch, memory, GPU) are fully validated.

### Human Verification Required

None. All verification can be performed programmatically through tests and CLI execution.

## Verification Details

### Plan 03-01: Registry Manifest Loading

**Truths verified:**
- ✓ System can load OpenClaw manifest from bundled registry directory
- ✓ Manifest contains version, OS requirements, architecture, and dependencies
- ✓ Manifest loading fails gracefully with clear error when manifest is missing or malformed

**Artifacts verified:**
```bash
# Manifest exists and is valid YAML
$ cat src/clawrium/platform/registry/openclaw/manifest.yaml
name: openclaw
description: "Open-source AI assistant framework"
entries:
  - version: "0.1.0"
    os: ubuntu
    os_version: "24.04"
    ...

# Registry module exports all required functions
$ python -c "from clawrium.core.registry import load_manifest, list_claws, get_claw_info, ManifestNotFoundError, ManifestParseError"
# (no error)

# Tests pass
$ uv run pytest tests/test_registry.py -v
14 passed in 0.03s
```

**Key links verified:**
- ✓ registry.py uses importlib.resources.files() to read manifests (line 81)
- ✓ ManifestNotFoundError raised for missing claws (line 86)
- ✓ ManifestParseError raised for malformed YAML (lines 95, 110)

### Plan 03-02: OS Detection in Hardware Info

**Truths verified:**
- ✓ HardwareInfo includes OS distribution and version detected via Ansible facts
- ✓ OS info (os, os_version) is gathered alongside existing hardware facts
- ✓ Hosts added via clm host add now have os and os_version in hardware dict

**Artifacts verified:**
```bash
# HardwareInfo has os fields
$ grep -n "os:" src/clawrium/core/hardware.py
34:    os: str  # lowercase distribution name (e.g., "ubuntu", "debian")
35:    os_version: str  # distribution version (e.g., "24.04", "12")

# Extraction uses ansible_distribution
$ grep -n "ansible_distribution" src/clawrium/core/hardware.py
53:        "os": facts.get("ansible_distribution", "unknown").lower(),
54:        "os_version": str(facts.get("ansible_distribution_version", "unknown")),

# Tests pass
$ uv run pytest tests/test_hardware.py -v
143 passed in 0.22s
```

**Key links verified:**
- ✓ extract_hardware_from_facts() extracts OS from Ansible facts (lines 53-54)
- ✓ OS names normalized to lowercase (Ubuntu → ubuntu) for consistency
- ✓ Defaults to "unknown" when facts missing (graceful degradation)

### Plan 03-03: Compatibility Checking

**Truths verified:**
- ✓ System validates host capabilities against claw requirements
- ✓ Compatibility check returns pass/fail with specific reasons
- ✓ All requirement types are checked: OS, arch, memory, GPU, dependencies (deferred)

**Artifacts verified:**
```bash
# CompatibilityResult type exists
$ grep -n "class CompatibilityResult" src/clawrium/core/registry.py
44:class CompatibilityResult(TypedDict):

# check_compatibility function exists
$ grep -n "def check_compatibility" src/clawrium/core/registry.py
198:def check_compatibility(

# Compatibility tests pass
$ uv run pytest tests/test_registry.py -v -k compatibility
8 passed in 0.02s
```

**Test verification:**
```python
# Compatible hardware
hardware = {'os': 'ubuntu', 'os_version': '24.04', 'architecture': 'x86_64', 'memtotal_mb': 4096, ...}
result = check_compatibility('openclaw', hardware)
assert result['compatible'] == True
assert result['matched_entry']['version'] == '0.1.0'

# Incompatible hardware
hardware = {'os': 'debian', 'os_version': '12', ...}
result = check_compatibility('openclaw', hardware)
assert result['compatible'] == False
assert 'Requires ubuntu 24.04, host has debian 12' in result['reasons']
```

**Key links verified:**
- ✓ check_compatibility uses HardwareInfo schema (line 200)
- ✓ Iterates manifest entries for sparse matrix matching (lines 240-291)
- ✓ Validates OS, OS version, arch, memory, GPU (lines 244-275)
- ✓ Returns specific failure reasons (e.g., "Requires X, host has Y")

### Plan 03-04: Registry CLI Commands

**Truths verified:**
- ✓ User runs clm registry list and sees available claws with versions
- ✓ User runs clm registry show <claw> and sees full manifest details
- ✓ CLI output uses Rich tables consistent with existing commands

**Artifacts verified:**
```bash
# Registry CLI module exists
$ cat src/clawrium/cli/registry.py | head -20
"""Registry commands for browsing available claws."""
...
registry_app = typer.Typer(...)

# Registered in main
$ grep registry src/clawrium/cli/main.py
from clawrium.cli.registry import registry_app
app.add_typer(registry_app, name="registry")

# CLI tests pass
$ uv run pytest tests/test_cli_registry.py -v
4 passed in 0.11s
```

**CLI execution verified:**
```bash
$ uv run clm registry list
                         Available Claws
┏━━━━━━━━━━┳━━━━━━━━━━━━━━━━┳━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┓
┃ Name     ┃ Latest Version ┃ Description                        ┃

└─────────┴──────────────┴──────────────┴────────────┴──────────────┘

Dependencies:
  - nodejs >=18.0.0
  - nodejs >=20.0.0
```

**Key links verified:**
- ✓ registry.py imports list_claws, get_claw_info, load_manifest (lines 7-12)
- ✓ list_registry() calls list_claws() and get_claw_info() (lines 28-50)
- ✓ show() calls load_manifest() and displays manifest data (lines 54-97)
- ✓ main.py imports and registers registry_app (lines 7, 37)

---

## Success Criteria from ROADMAP.md

**Phase Goal:** Users can browse available claw types and validate compatibility before installation

**Success Criteria:**

1. ✓ **User runs `clm registry list` and sees OpenClaw with version and requirements**
   - Evidence: CLI execution shows Rich table with openclaw 0.1.0 and description
   - Test: `uv run clm registry list` displays openclaw entry

2. ✓ **System loads OpenClaw manifest from platform/registry/openclaw/ directory**
   - Evidence: manifest.yaml exists at bundled path, loaded via importlib.resources
   - Test: `load_manifest('openclaw')` returns ClawManifest with 2 entries

3. ✓ **System validates host capabilities against claw requirements and reports compatibility**
   - Evidence: check_compatibility() validates OS, arch, memory, GPU with specific reasons
   - Test: Compatible hardware returns True, incompatible returns False with reasons like "Requires ubuntu 24.04, host has debian 12"
