human_verification:

- test: "Run cargo test --package tcptop on Linux VM"
|
|
expected: "All 13 pipeline tests and 6 CSV tests pass on Linux (no macOS-only workarounds)"
|
|
why_human: "Test suite was manually approved per Plan 03 Task 2, but automated run was only confirmed on macOS. Linux confirmation requires VM access."
|
|
- test: "Run sudo tcptop --log /tmp/test.csv --interval 2, generate traffic, inspect CSV"
|
|
expected: "CSV file exists with header row (16 columns) and data rows with real connection data and RFC3339 timestamps"
|
|
why_human: "Headless CSV logging requires root + eBPF on Linux. Cannot verify functionally on macOS."
|
|
- test: "Run man -l doc/tcptop.1 on Linux VM"
|
|
expected: "Man page renders correctly with all sections visible including EXAMPLES"

**Status:** gaps_found (1 gap)

### 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.
