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.
