# Phase 3 Verification — Orca v0.6 P03

**Phase**: P03 — Doctor Extensions + Audit Logging
**REQ Coverage**: REQ-052
**Verification date**: 2026-08-03
**Result**: ✅ PASS (all 4 layers)

## Structural Verification

- ✅ `go build ./...` — PASS
- ✅ `go vet ./...` — PASS
- ✅ `gofmt -l .` — PASS
- ✅ `make lint` — PASS
- ✅ `internal/osdetect` new shared package (extracted from cli to avoid import cycle)
- ✅ `doctor.OS()` and `doctor.Proxmox()` follow existing check pattern (Check struct, Result, Run func)
- ✅ `doctor.All()` extended with OS + Proxmox in logical order

## Behavioral Verification

### REQ-052: doctor os + doctor proxmox + audit logging
- ✅ `TestOSCheck_MissingLocalhostNode`: no localhost node → FAIL with clear message
- ✅ `TestOSCheck_Match`: stored os matches detected → PASS
- ✅ `TestOSCheck_Drift`: stored os differs from detected → WARN ("OS drift: init=debian, now=ubuntu")
- ✅ `TestProxmoxCheck_NoProxmoxNodes`: zero proxmox nodes → WARN ("no proxmox nodes registered")
- ✅ `TestProxmoxCheck_UnreachableNode`: unreachable proxmox node → FAIL with node name
- ✅ E2E: `orca doctor os` → PASS (os=ubuntu matches)
- ✅ E2E: `orca doctor proxmox` → WARN (no proxmox nodes)
- ✅ E2E: `orca doctor os --json` → valid JSON
- ✅ E2E: `orca doctor` (full) → 6 PASS / 1 WARN / 1 FAIL (network=daemon not running, expected)
- ✅ osdetect package: 11 tests (ubuntu/debian/alpine/pve parsing, quoted/unquoted, missing ID, comments, fallback)
- ✅ Audit logging: proxmox.BootstrapProxmox emits `proxmox.bootstrap_ok` (P02); doctor checks are read-only

## Security Verification

- ✅ Doctor checks are strictly read-only (no state changes)
- ✅ SSH probe uses orca SSH key (not password) — no password in doctor flow
- ✅ TOFU host-key verification via knownhosts.New (D-035)
- ✅ 3s timeout per proxmox probe (D-038 bounded-probe-timeout pattern)
- ✅ No secrets in doctor output (fingerprints only, never private keys)

## Quality Verification

- ✅ `go test -race -count=1 ./...` — all PASS (13 packages)
- ✅ Test coverage: osdetect (11 tests), doctor OS (3 tests), doctor Proxmox (2 tests)
- ✅ Error wrapping with `fmt.Errorf("...: %w", err)` (REQ-018)
- ✅ `context.Context` propagation (REQ-017)
- ✅ No goroutine leaks (netDialer cleans up on ctx cancellation)
- ✅ D-036: doctor os handles pre-0006 rows (empty os field → WARN)
