# Milestone Validation: M001
## Success Criteria Checklist
| # | Criterion | Status | Evidence |
|---|-----------|--------|----------|
| 1 | `cargo check` passes on macOS, Linux, and Windows targets | ⚠️ Partial | macOS + Windows MSVC pass; Linux cross-compile blocked by missing `x86_64-linux-gnu-gcc` toolchain on Windows host (code review confirms `#[cfg]` guards correct, but no compilation proof) |
| 2 | Daemon started with `--tcp 127.0.0.1:9876` accepts TCP connections and responds correctly | ❌ Missing | No live daemon start verified; S04 integration smoke test never executed due to auto-mode tools-policy blocker |
| 3 | Client with `--tcp 127.0.0.1:9876` returns same results as local transport | ❌ Missing | S04 T02 (TCP vs local comparison) still pending; no real daemon round-trip verified |
| 4 | Client with `--tcp 127.0.0.1:9999` (unreachable) fails with clear error within 15s | ✅ Pass | `test_send_tcp_connection_refused` integration test passes (S03); 15s connect timeout configured in `send_tcp()` |
| 5 | Commands without `--tcp` still work via local transport (no regression) | ✅ Pass | 35/35 tests pass including 32 pre-existing tests; S01 UAT covers local socket path |
## Slice Delivery Audit
| Slice | Status | Summary | Tasks | Assessment |
|-------|--------|---------|-------|------------|
| S01 | complete | ✅ Valid SUMMARY.md | 3/3 done | ✅ Transport traits + TCP server + cross-platform compile verified |
| S02 | complete | ✅ Valid SUMMARY.md | 3/3 done | ✅ TCP client transport + --tcp flag + daemon status/stop verified |
| S03 | complete | ✅ Valid SUMMARY.md | 2/2 done | ✅ Integration tests (mock server round-trip, connection refused, liveness) + 35/35 suite pass |
| S04 | complete ⚠️ | ❌ BLOCKER placeholder (auto-mode tools-policy rejection) | 1/2 done, 1 pending | ❌ Real e2e daemon-client TCP integration test never executed; SUMMARY is not valid evidence |
## Cross-Slice Integration
**S01 → S02**: ✅ PASS — Transport traits (`Listener`/`Connector`), `TcpListener`, `TcpConnector`, `handle_connection` produced in S01; consumed in S02 to build client transport. Source artifacts confirmed via grep.
**S01 → S03**: ⚠️ FLAG — S03 frontmatter `requires: slice S01 provides: (empty)``provides` field blank, contract not documented. Artifacts exist and were tested, but dependency chain is opaque.
**S02 → S03**: ⚠️ FLAG — S03 frontmatter `requires: slice S02 provides: (empty)` — same documentation gap.
**S02 → S04**: ❌ FAIL — S04 SUMMARY is a blocker placeholder; T01 has no task summary; T02 still pending. No real daemon-client integration test written or executed.
**S03 → S04**: ❌ FAIL — S03 produced integration-tested TCP client (mock server), but S04 never consumed it for real binary-level testing.
Source verification confirmed: `Listener` trait, `Connector` trait, `TcpListener`, `TcpConnector`, `handle_connection`, `send_tcp`, `is_alive_tcp`, `Start {}` subcommand, `--tcp` flag, `tcp_addr` param, `start_daemon` — all present in source.
## Requirement Coverage
| Requirement | Status | Evidence |
|---|---|---|
| R002 — TCP transport with timeouts, hard error, no silent fallback | COVERED | S02: `send_tcp()` with 15s connect/120s read-write timeout, hard error on failure. S03: 3 integration tests (round-trip, connection refused, liveness) + 35/35 suite pass + cross-platform compilation. |
| R004 — Global --tcp flag on Cli struct | COVERED | S02: `tcp: Option<String>` on Cli struct, wired through all 14 cmd_* functions. `--tcp` visible in CLI help. |
| R007 — ensure_daemon() hard-errors on TCP failure | COVERED | S02: `ensure_daemon()` hard-errors on TCP connection failure; `send_tcp()` returns `Result`; no silent fallback. |
All formally tracked requirements (R002, R004, R007) are covered at the unit/mock integration test level. However, the milestone-level e2e integration proof (S04) remains unexecuted.
## Verification Class Compliance
| Class | Planned Check | Evidence | Verdict |
|-------|---------------|----------|---------|
| **Contract** | Transport traits defined, all three implementations compile, protocol handling is shared | Listener/Connector traits in `src/transport/`; TCP, Unix socket, Windows named pipe impls; `cargo check` passes native + Windows MSVC; `handle_connection` shared via generic function | ✅ Pass |
| **Integration** | Daemon listens on local + TCP simultaneously, client connects via TCP and gets correct response | S01: daemon wired for dual listen. S03: mock-server integration tests confirm send_tcp round-trip. **S04 (real daemon-client integration) did not execute** | ⚠️ Flag — partial; real e2e missing |
| **Operational** | Daemon starts with `--tcp`, handles bind errors cleanly, client fails with clear error when TCP unreachable | `ensure_daemon()` hard-errors on TCP failure (S02); connection-refused test passes (S03). **No evidence of bind error handling** (port-in-use scenario) or clean shutdown behavior | ⚠️ Flag — partial; bind-error and shutdown untested |
| **UAT** | Manual smoke test: daemon on TCP + client queries return same data as local transport | S01S03 UATs cover compilation, flag visibility, and mock tests. **S04 UAT does not exist** — the live daemon smoke test was never performed | ❌ Missing |
## Verdict Rationale
All three slices S01S03 are properly completed with valid summaries, passing tests, and cross-platform compilation. The core TCP transport implementation (traits, server, client, --tcp flag) is fully functional and verified at unit and mock-integration level. However, S04 — the end-to-end integration smoke test proving real daemon ↔ client communication over TCP — was never executed due to an auto-mode tools-policy blocker (planning-dispatch unit attempted to write source files). S04's SUMMARY.md is a placeholder, not valid evidence, and 1 of 2 tasks remains pending despite the DB marking the slice as "complete." This leaves the milestone's highest-level acceptance criterion (real TCP round-trip with actual `wx` binary) unverified. Verdict: needs-attention.
