OPS-04 (Homebrew) was incorrectly assigned to Phase 3 — CONTEXT.md D-16 explicitly defers to Phase 4. Fixed: moved OPS-04 to Phase 4/Pending in REQUIREMENTS.md.
test expected why_human
Run cargo test --package tcptop on Linux VM All 13 pipeline tests and 6 CSV tests pass on Linux (no macOS-only workarounds) Test suite was manually approved per Plan 03 Task 2, but automated run was only confirmed on macOS. Linux confirmation requires VM access.
test expected why_human
Run sudo tcptop --log /tmp/test.csv --interval 2, generate traffic, inspect CSV CSV file exists with header row (16 columns) and data rows with real connection data and RFC3339 timestamps Headless CSV logging requires root + eBPF on Linux. Cannot verify functionally on macOS.
test expected why_human
Run man -l doc/tcptop.1 on Linux VM Man page renders correctly with all sections visible including EXAMPLES Rendering man page requires a terminal environment with man(1) installed.

Phase 03: Output & Distribution Verification Report

Phase Goal: Output & Distribution — CSV logging, help/man page, packaging config, test coverage Verified: 2026-03-22T05:30:00Z Status: gaps_found (1 gap) Re-verification: No — initial verification

Goal Achievement

Observable Truths

# Truth Status Evidence
1 User can run tcptop --log output.csv and get a CSV file with connection snapshots VERIFIED run_headless in main.rs (line 181) creates CsvLogger::new, calls write_snapshot on each tick
2 CSV file has a header row with all 16 column names VERIFIED CsvRow derives Serialize — csv crate auto-generates header from field names; test_csv_header_row asserts all 16 names
3 Each snapshot row includes a timestamp; all rows in one tick share the same timestamp VERIFIED Utc::now().to_rfc3339() called once per tick (main.rs line 236), passed to write_snapshot; test_csv_timestamp_consistency verifies
4 Headless mode never initializes the terminal (no ratatui::init) VERIFIED if let Some(ref log_path) = cli.log branches BEFORE ratatui::init() (main.rs lines 62-70); run_headless contains no ratatui imports
5 CSV writer tests pass without requiring root or Linux VERIFIED csv_test.rs uses tempfile::NamedTempFile — no syscalls, no eBPF; 6 tests confirmed passing on macOS
6 Man page exists with NAME, SYNOPSIS, DESCRIPTION, OPTIONS, EXAMPLES, and EXIT STATUS VERIFIED doc/tcptop.1 (144 lines) contains all 6 required sections plus INTERACTIVE KEYS, REQUIREMENTS, SEE ALSO, AUTHORS
7 Package metadata in Cargo.toml satisfies crates.io requirements VERIFIED tcptop/Cargo.toml has description, license = "MIT", repository, readme, keywords, categories
8 cargo-deb and cargo-generate-rpm configuration includes the man page asset VERIFIED [package.metadata.deb] assets reference ../doc/tcptop.1 → usr/share/man/man1/tcptop.1; rpm config mirrors this
9 --help output includes the --log flag documentation VERIFIED log: Option<String> with doc comment in Cli struct (main.rs line 47-49); clap auto-generates --help from this
10 Aggregator edge cases and filtering logic are tested (9 new tests) VERIFIED pipeline_test.rs (367 lines) contains all 9 required test functions; all cover non-trivial behavior
11 OPS-04: Tool is installable via Homebrew FAILED No Homebrew formula exists. Context D-16 deferred this to Phase 4, but Plan 02 claims OPS-04 complete.

Score: 10/11 truths verified

Requirements Coverage

Requirement Source Plan Description Status Evidence
OUTP-01 03-01 User can log connection data to CSV via --log <path> SATISFIED --log flag in Cli struct; run_headless event loop; CsvLogger wired
OUTP-02 03-01 CSV output includes header row and periodic snapshots SATISFIED CsvRow Serialize derive gives header; write_snapshot called on each tick
OUTP-03 03-02 Tool provides --help with clear usage documentation SATISFIED All 8 Cli fields have doc comments; clap generates --help automatically
OUTP-04 03-02 Tool ships with a man page SATISFIED doc/tcptop.1 (144 lines) with complete sections and all flag docs
OPS-03 03-02 Tool is installable via cargo install SATISFIED description, license, repository in Cargo.toml satisfy crates.io minimum
OPS-04 03-02 Tool is installable via Homebrew NOT SATISFIED No Homebrew formula file created. CONTEXT D-16 deferred to Phase 4; REQUIREMENTS.md marks as Phase 3 Complete — these are inconsistent.
OPS-05 03-01, 03-03 Test coverage for core data processing and display logic SATISFIED 6 CSV tests + 9 new pipeline tests covering aggregator, filtering, rates

Orphaned requirements check: REQUIREMENTS.md maps OUTP-01, OUTP-02, OUTP-03, OUTP-04, OPS-03, OPS-04, OPS-05 to Phase 3. All 7 are claimed by plans (Plan 01: OUTP-01, OUTP-02, OPS-05; Plan 02: OUTP-03, OUTP-04, OPS-03, OPS-04; Plan 03: OPS-05). No orphaned requirements.

Anti-Patterns Found

File Line Pattern Severity Impact
None — — — No stub patterns, empty implementations, or placeholder comments found in any phase-modified file.

Specific checks run on csv_writer.rs, csv_test.rs, main.rs, pipeline_test.rs, doc/tcptop.1:

  • No TODO/FIXME/HACK/PLACEHOLDER comments
  • No return null / return {} / return [] patterns
  • No hardcoded empty data flowing to output paths
  • run_headless makes real eBPF collector + aggregator calls, not mocks

Human Verification Required

1. CSV Logging on Linux VM

Test: sudo tcptop --log /tmp/test.csv --interval 2, generate traffic with curl, kill after 8s, inspect /tmp/test.csv Expected: File has a header row with 16 columns, followed by data rows with RFC3339 timestamps and real connection data Why human: Requires root + Linux kernel with eBPF. eBPF probes cannot be loaded on macOS.

2. Full Test Suite on Linux

Test: cargo test --package tcptop on the dev-debian VM Expected: All 13 pipeline tests and 6 CSV tests pass; no Linux-specific compilation errors Why human: Tests that require timing (test_udp_idle_timeout sleeps 6s, test_rate_calculation_across_ticks sleeps 100ms) may behave differently under VM load. Human confirmation per Plan 03 Task 2 was recorded but commit was marked "approved (human-verify, no commit)" — treated as human attestation.

3. Man Page Rendering

Test: man -l doc/tcptop.1 on the Linux VM Expected: All sections render correctly; EXAMPLES section shows formatted command examples; no troff rendering errors Why human: Troff/groff rendering depends on the terminal and man implementation. File content is correct but visual rendering must be confirmed.

Gaps Summary

1 gap blocking full OPS-04 compliance:

OPS-04 states "Tool is installable via Homebrew." No Homebrew formula exists in the repository. The phase CONTEXT document (D-16) explicitly states "Homebrew/macOS packaging deferred to Phase 4," which is a coherent architectural decision since Phase 4 is the macOS backend phase.

However, Plan 02's requirements frontmatter claims OPS-04 as completed, and REQUIREMENTS.md marks it [x] Complete for Phase 3. This is a documentation inconsistency — the work was deliberately deferred, not forgotten, but the requirement tracking says it is done.

Resolution options (for /gsd:plan-phase --gaps):

  • Option A: Update REQUIREMENTS.md to move OPS-04 to Phase 4 with status Pending (matches the actual plan in CONTEXT D-16)
  • Option B: Create a minimal Homebrew formula stub that installs the pre-built binary (satisfies the requirement without needing the macOS backend)

The underlying work (csv logging, man page, packaging config, test coverage) is complete and correct. This gap is a requirements-tracking inconsistency, not a missing implementation in the phase's primary deliverables.
