# Phase 1 Verification — v0.8 Coverage & Trust Hardening

**Phase**: P01 — Coverage uplift round 2
**Milestone**: v0.8
**REQ**: REQ-057
**Date**: 2026-08-04
**Result**: ✅ PASS (all 4 layers)

## Layer 1 — Structural ✅

- `go build ./...` PASS (no compile errors)
- `go vet ./...` PASS (no warnings)
- No TODOs/FIXMEs/stubs in production code (the 3 pre-existing placeholders in `internal/cli/job.go:78`, `internal/engine/scheduler.go:115`, `internal/security/tls_config.go:90` are unchanged from v0.7 and out of scope for P01)
- All test files resolve imports correctly
- The proxmox `sessionRunner` seam (T01.1) is backward compatible — `BootstrapProxmox` callers unchanged

## Layer 2 — Behavioral ✅

- `go test ./...` PASS (all 14 packages)
- `go test -race ./...` PASS (cli 98s, engine 47s, store 88s, transport 22s, all others fast)
- Coverage targets met (T01.12):
  - ≥70% floor: engine 88.9%, proxmox 87.1%, cli 76.2%, transport 93.0%, store 84.7%, jobspec 90.5%
  - ≥50% floor: audit 100.0%, certpaths 100.0%, cmd/orca 80.0%
- GRILL condition #3 escape valve NOT needed (cli hit 76.2%, above 70%)
- T01.2 (conditional `peerDispatcher` seam) NOT added — engine reached 88.9% via httptest + stubs
- REQ-057 covered: all 9 target packages hit their tiered floor

## Layer 3 — Security ✅

- P01 is a test-only phase (the only production change is T01.1's `sessionRunner` interface extraction + T01.11's `main()→run()` refactor)
- No new input paths, no new network surfaces, no new crypto
- The `sessionRunner` seam does not leak test concerns into production (default `sshSessionRunner` wraps the real SSH session; the seam is only injectable via the package-level var pattern matching `sshDialer`)
- `cmd/orca/main.go` refactor: `run() int` returns exit code; `main()` calls `os.Exit(run())` — no security impact (same behavior, testable)
- No secrets in test code (all test DBs use `:memory:` or temp dirs; no real credentials)

## Layer 4 — Quality ✅

- Tests follow existing conventions (table-driven, `t.Run` subtests, `t.Helper()` in setup funcs)
- Reuse of existing helpers: `openTestDB`, `withFastWatch`, `initTestEnv`, `resetRootFlags`, `discardWriter`, `stubDispatcher` pattern
- No flaky tests detected (all pass on repeated runs with `-race`)
- Test file naming follows `*_test.go` convention
- No over-testing: daemon.go excluded from cli coverage (covered by `internal/daemon/server_test.go`)
- P0 issues: none. P1+ issues: none flagged.

## Requirement Coverage

| REQ | Status | Evidence |
|-----|--------|----------|
| REQ-057 | ✅ Complete | All 9 packages hit tiered floor; `go test -cover` confirms; `go test -race` PASS |

## Lessons

- The `sessionRunner` seam pattern (package-level var + default init in entry func) is the canonical way to add testability to orca's SSH-dependent packages. Future SSH-adjacent packages should follow it.
- `httptest.NewTLSServer` sufficed for engine 70% without needing the conditional `peerDispatcher` seam — the plan's "only if needed" guard worked as intended.
- The cli package's 84s test time is dominated by `--watch` integration tests with real poll intervals. Future coverage work should consider reducing the `withFastWatch` interval further or extracting the watch logic for unit-level testing.
