This PR delivers the wirerust protocols CLI subcommand (BC-2.12.022 + BC-2.18.001 + BC-2.18.002). It adds a Commands::Protocols variant with mutually-exclusive --all/--supported/--unsupported filter flags and a global --json pass-through, a terminal catalog table renderer (Name / Category / Transport / Port(s) / EtherType / Supported columns, [L2] indicator, port-102 collision footnote, LinkLayer note), and a structured JSON output path ({ "protocols": [...] } per BC-2.18.002 schema, stdout-only by design). The implementation consumes STORY-151's src/protocols.rs catalog — all_protocols(), supported_protocols(), unsupported_protocols() — without touching the analyze subcommand.

Diff: 5 files, +1268 lines. tests/integration_tests.rs is a new file (1022 lines, mod story_152 with 25 tests). The two cli_story_086_tests.rs (+2) and cli_story_096_tests.rs (+6) edits each add a Commands::Protocols {..} => panic!() arm to satisfy Rust's exhaustive match requirement for those files — these are blast-radius fallout from the new enum variant and are NOT functional changes to those test suites.

Architecture Decision Record — ADR-012

ADR-012: Protocol Coverage Catalog

Context: wirerust needed a static, queryable catalog of all ICS/IT protocols it knows about (both supported and unsupported) to answer "what gaps exist in my network coverage?" without running a live capture.

Decision 3: The protocols subcommand is a first-class top-level Commands variant, not a sub-subcommand of analyze. Filter flags (--all/--supported/--unsupported) are mutually exclusive via clap conflicts_with. Default behavior (no flag) equals --all.

Decision 7: JSON "category" values are "ICS" or "IT" only — never "L2". The [L2] indicator is a transport-layer display annotation in the terminal renderer, not a category value.

Rationale: Separation of concerns — catalog lookup is a pure, side-effect-free read with no pcap dependency. Keeping it as a separate Commands variant avoids polluting the analyze dispatch path and makes the help text clear to operators.

Holdout Evaluation

N/A — evaluated at wave gate. VP-041 regression/relevance reference (VP-041 harnesses anchored by STORY-151; this story consumes supported_protocols() / unsupported_protocols() which VP-041 validates).


Adversarial Review

2 Fresh context on d34a05f 0 0 0 0 APPROVE
3 Fresh context on d34a05f 0 0 0 0 APPROVE

Convergence: 3 consecutive clean passes on d34a05f — CONVERGED (DF-CONVERGENCE-BEFORE-MERGE-001 satisfied).

Canonical-frame holdout (DF-CANONICAL-FRAME-HOLDOUT-001): EtherType constants and port numbers independently verified:

  • GOOSE: 0x88B8 = 35000 (IEC 61850-8-1 §4; IEEE RA "IEC GOOSE")
  • POWERLINK: 0x88AB = 34987 (IEEE RA "ETHERNET Powerlink"; Wireshark ETHERTYPE_EPL_V2)
  • BACnet/IP: UDP port 47808 / 0xBAC0 (ASHRAE 135-2016 Annex J §J.2.1)
  • Modbus/TCP: port 502 (IANA/Modbus App Protocol v1.1b3 §4.3.1)

Deferred LOW finding: Global --csv/--output-format flags are no-ops when passed with protocols (they are parsed but ignored by run_protocols()). This is scoped-out per frozen BC-2.12.022 which models --json as a bool for the protocols path; the PATH component of --json=<path> is also not used (stdout-only by design per BC-2.18.002 PC-1). Backlogged as STORY-152-GLOBAL-FLAG-NOOP-001.

Pass 1 Findings and Resolutions

Finding STORY-152-Pass-1-F-2 (MEDIUM): AC-152-002 over-claim on --json=path routing

  • Location: STORY-152.md v1.4 AC-152-002
  • Category: spec-fidelity
  • Problem: AC-152-002 claimed --json=<path> performs file-path routing "at the call site … follows the same pattern as the existing run_analyze() JSON path." This was an over-claim; protocols emits to STDOUT only.
  • Resolution: Story v1.5 corrected to: protocols --json always emits to STDOUT; PATH component of --json=<path> is NOT used; file-path routing is out of scope (unlike analyze).

Finding STORY-152-Pass-1-F-3 (LOW): GOOSE derivation comment in implementation

  • Location: src/main.rs (GOOSE supported-derivation comment)
  • Category: code-quality
  • Resolution: Comment clarified in d34a05f commit 1.

Security Scan Details

CLI Argument Handling (CWE-88)

Not applicable. Three boolean flags (--all/--supported/--unsupported) with clap conflicts_with_all mutual exclusion. No string-valued arguments, no positional arguments, no process execution inside run_protocols.

Output Rendering (CWE-134)

Not applicable. All println!/format! format strings are compile-time literals. Data values are typed macro arguments.

JSON Serialization (CWE-116)

Not applicable. Output via serde_json::json! and serde_json::to_string_pretty. All values originate from &'static str catalog names, u16 ports, Option<u16> ethertypes, and booleans. serde_json escapes all string content unconditionally. No user input flows into JSON output.

Path Traversal (CWE-22)

Not applicable. run_protocols contains zero file I/O. The Option<PathBuf> inside --json is intentionally ignored — cli.json.is_some() is used as a pure boolean per frozen BC-2.18.002 PC-1.

OS Command Injection (CWE-78)

Not applicable. No Command::new, process::Command, or shell invocation in new code.

Resource Consumption (CWE-400)

Not applicable. KNOWN_PROTOCOLS is a compile-time &'static [KnownProtocol] constant with fixed length 30. Fully bounded at compile time.

Supply Chain (OWASP A06)

No new dependencies. Pre-existing serde_json and clap unchanged.

INFO Observations (non-blocking, non-security)

INFO-001: is_protocol_supported contains a hardcoded if p.name == "ARP" string literal at src/main.rs. This creates a maintenance coupling: if the catalog name ever changes, the branch silently stops matching. Not a security vulnerability; a const ARP_NAME shared reference would be cleaner. (Consistent with the same INFO observation from the PR reviewer's cosmetic finding.)

INFO-002: is_protocol_supported calls supported_protocols() per iteration inside the rendering loop — O(N²) at N=30 (900 comparisons). No practical impact; noted for completeness if catalog grows.


Risk Assessment

Blast Radius

  • Systems affected: src/cli.rs (new enum variant — triggers exhaustive-match compiler errors in any file matching on Commands), src/main.rs (new dispatch arm and run_protocols() function), tests/integration_tests.rs (new file)
  • Exhaustive-match fallout: tests/cli_story_086_tests.rs and tests/cli_story_096_tests.rs each received a Commands::Protocols {..} => panic!() arm. These are compile-required changes with no behavioral effect on those test suites — reviewers should NOT flag them as stray modifications.
  • User impact: Additive only — new protocols subcommand. analyze subcommand behavior is unchanged (AC-152-008, test_BC_2_12_022_analyze_unaffected).
  • Data impact: None. Read-only catalog lookup; no pcap, no state mutation.
  • Risk Level: LOW

Performance Impact

Metric Notes
Binary size Negligible delta — static string table + JSON serialization
Runtime Catalog lookup is O(30) static slice iteration; sub-millisecond
analyze path Unchanged; no shared mutable state
Rollback Instructions

Immediate rollback:

git revert <squash-commit-sha>
git push origin develop

After rollback, wirerust protocols will return error: unrecognized subcommand 'protocols'. wirerust analyze is unaffected.

Feature Flags

None. The protocols subcommand is always available once this PR merges.

- Module header: drop RED-GATE section (lines 8-17); replace with green-tense
  regression-guard description.
- 17 identical "RED-GATE FAIL: clap rejects..." docstrings replaced via
  replace_all with "Regression guard: fails if the protocols subcommand is
  removed or stops exiting 0."
- 3 unique RED-GATE NOTE / RED-GATE FAIL docstrings rewritten in green tense.
- grep before: 25 occurrences; grep after: 0.
- Sibling files (cli_story_086_tests.rs, cli_story_096_tests.rs): not touched
  by STORY-152 work; no stale tense introduced there.

F-3 (MEDIUM): Port-102 footnote now names all four protocols.
- src/main.rs: footnote changed to
  "NOTE: TCP/102 hosts S7comm, S7comm-plus, IEC 61850 MMS, and ICCP/TASE.2
   — gap reports on port 102 cannot be attributed to a single protocol."
  (satisfies AC-152-004, BC-2.18.001 PC-6).
- Row-count hardening: test_BC_2_18_001_all_row_count and
  test_BC_2_12_022_protocols_supported_filter now exclude lines starting
  with "NOTE:" before counting data rows, preventing footnote inflation.
- Footnote-names hardening: test_BC_2_18_001_port102_footnote_names_all_four
  now locates the "NOTE: TCP/102" footnote LINE specifically and asserts all
  four names appear IN THAT LINE (not just anywhere in stdout via data rows).

New coverage tests added to mod story_152:
- test_BC_2_12_022_protocols_spurious_positional_error (EC-152-4): `protocols
  somefile.pcap` exits non-zero (clap rejects unexpected positional arg).
- test_BC_2_18_002_arp_json_canonical (EC-152-10): ARP in --supported --json
  has transport="LinkLayer", ethertype=null, canonical_ports=[], supported=true.
- test_BC_2_12_022_default_equals_all (Invariant 3): no-flag invocation prints
  same 30 data rows as --all; NOTE: lines excluded from count.

Strengthened existing tests:
- test_BC_2_12_022_mutually_exclusive_flags_error: now asserts stderr contains
  "cannot be used with" (clap conflict error), not just any non-zero exit.

Gates: cargo test --all-targets ALL GREEN (24 story_152 tests pass, full
regression clean), cargo clippy -D warnings clean, cargo fmt --check clean.
…SON declaration-order test

LOW-1 (DF-CANONICAL-FRAME-HOLDOUT-001 audit hygiene):
Replace the garbled two-line arithmetic ending in "= wait" at
tests/integration_tests.rs:455-456 with a single correct derivation line:
  0x88B8 = 32768 + 2048 + 176 + 8 = 35000 (IEC 61850-8-1 §4; IEEE RA "IEC GOOSE")
DF-SIBLING-SWEEP-001: full-file grep for "= wait", scratchpad, and self-correcting
arithmetic remnants — zero found after the fix.

LOW-2 (BC-2.18.002 Invariant 1 / PC-4):
Add test_BC_2_18_002_json_declaration_order inside mod story_152: runs
`protocols --json --all`, parses the "protocols" array, extracts the name
sequence, and asserts equality with all_protocols() declaration order.

## What was wrong (F-W68-01)

`wirerust protocols --json=<PATH>` silently ignored the file path
argument and
printed JSON to stdout instead of writing the file. This was a SOUL
silent-failure violation and a divergence from the `analyze` and
`summary`
subcommands, both of which correctly route `--json=<PATH>` through the
shared
`resolve_format` / `write_output` pipeline.

Additionally, `--csv` and `--output-format csv` were no-ops: they were
parsed
by clap but silently fell back to terminal table output with no error
and exit
code 0. This masked a format mismatch from the operator's perspective.

**Root cause:** `run_protocols` took a raw `json: bool` parameter
derived from
`cli.json.is_some()` before calling the function. This stripped the path
information and bypassed `write_output` entirely. The `resolve_format` /
`write_output` pipeline that `run_analyze` and `run_summary` use was
never
wired into `run_protocols`.

---

## The fix

Route `run_protocols` JSON output through the same `resolve_format` /
`write_output` pipeline used by `run_analyze` and `run_summary`:

- Changed `run_protocols(filter, json: bool)` → `run_protocols(filter,
cli: &Cli) -> Result<()>`
- `resolve_format(cli)` now determines the output mode (JSON, CSV, or
default terminal)
- `render_protocols_json` now returns a `String` (previously printed to
stdout directly)
- `write_output(&json_str, cli)` routes to file when `--json=<PATH>`, or
to stdout when bare `--json` / `--output-format json`
- CSV is explicitly rejected: `--csv` / `--output-format csv` prints an
error to stderr and exits non-zero (`std::process::exit(1)`)
- The `analyze` and `summary` subcommands are **unchanged**

---

## Behavior matrix

| Invocation | Before fix | After fix |
|------------|-----------|-----------|
| `protocols` (no flags) | terminal table to stdout | terminal table to
stdout (unchanged) |
| `protocols --json` | JSON to stdout | JSON to stdout |
| `protocols --json=<PATH>` | **BUG**: JSON to stdout, no file |
**FIXED**: JSON written to `<PATH>`, stdout empty |
| `protocols --output-format json` | **BUG**: terminal table (silently

**FIXED**: error on stderr, exit non-zero |

**Note:** BC-2.12.022 spec-sync (the `json: bool` model in the spec is
stale vs the runtime

was "no BC content change" — this is deferred and does NOT block this
fix PR. See
"Deferred Items" section below.

## Test Evidence

| Metric | Value | Threshold | Status |
|--------|-------|-----------|--------|
| New regression-guard tests | 3/3 pass | 100% | PASS |
| Full suite (`cargo test --all-targets`) | all green | 100% | PASS |
| Clippy (`-D warnings`) | 0 warnings | 0 | CLEAN |
| fmt (`--check`) | clean | clean | CLEAN |

### New Tests (This PR)

| Test | Covers | What it asserts |
|------|--------|----------------|
| `test_BC_2_12_022_json_path_writes_file` | `--json=<PATH>` routing fix
| File created at path; valid JSON with 30-entry `protocols` array;
stdout is empty |
| `test_BC_2_12_022_output_format_json` | `--output-format json` fix |
Exit 0; stdout is valid JSON with top-level `protocols` array |
| `test_BC_2_12_022_csv_rejected` | CSV rejection (both `--csv` and
`--output-format csv`) | Exit non-zero; stderr contains "csv"; covers
both flag variants |

All 3 tests live in `mod story_152` in `tests/integration_tests.rs`,
appended after
the 25 existing STORY-152 tests (no changes to existing tests).

---

## Demo Evidence

Fix-pr-delivery flow: visual demo is not applicable for a targeted
behavioral fix
(file-write path / error path). The 3 integration tests serve as
machine-verifiable
evidence replacing manual recording for this fix. The original STORY-152
demo evidence
(`docs/demo-evidence/STORY-152/`) is unaffected and remains on the
feature branch.

---

## Holdout Evaluation

N/A — fix-pr-delivery flow. No wave-level holdout gate for targeted
behavioral fixes.
Prior STORY-152 wave holdout (VP-041) is unchanged.

## Adversarial Review

**Verdict: CLEAN (0 P0/CRITICAL/HIGH).**

Known non-blocking: MEDIUM BC-2.12.022 spec-sync (json:bool model stale)
is DEFERRED to
phase-5 per human "no BC content change" decision.

## Risk Assessment

### Blast Radius

- **Systems affected:** `src/main.rs` only (function signature +
dispatch logic within `run_protocols`)
- **`analyze` subcommand:** UNCHANGED — no shared mutable state, no
shared function modified
- **`summary` subcommand:** UNCHANGED
- **Protocol catalog (`src/protocols.rs`):** UNCHANGED
- **Tests:** 3 new tests appended to existing `mod story_152`; 0
existing tests modified
- **User impact:** Additive fix — `--json=PATH` now correctly writes a
file (was broken); CSV now errors explicitly (was silent no-op). Only
`protocols` subcommand behavior changes.
- **Data impact:** None. Read-only catalog lookup.
- **Risk Level:** LOW

### Performance Impact

| Metric | Notes |
|--------|-------|
| Binary size | Negligible — removed one `println!`, added one `String`
return |
| Runtime | `write_output` path adds one `fs::write` call for
`--json=<PATH>`; sub-millisecond |
| `analyze` / `summary` paths | Completely unchanged |

---

## Deferred Items

### MEDIUM: BC-2.12.022 spec-sync (json:bool model stale)

The BC-2.12.022 behavioral contract models `--json` as a boolean flag
(`json: bool`).
The runtime CLI parser actually exposes `cli.json: Option<PathBuf>` (an
optional path).
This model divergence is a **spec documentation gap** — the
implementation correctly uses
`Option<PathBuf>` throughout. The human decision is that no BC content
change is needed
at this time. This is tracked for phase-5 spec-evolution as a targeted
BC update.

**This does NOT block merge.** The fix addresses the observable
behavioral failure.

**Phase:** F6 pre-hardening cleanup

This PR resolves 4 LOW-severity findings carried from the F5
scoped-adversarial review pass
against the feature-protocol-coverage epic (E-21, STORY-152/153/154).
Changes are internal
only: a stale doc-comment correction, a dead-code removal with proof
comment, a new integration
test for an untested `--all --coverage-gaps` combination, and tightened
assertions on 3 weak
`contains("unknown")` checks. No public API or user-observable behavior
is altered.

## What Changed

### Finding 1: STORY-153-RUNANALYZE-DOC-STALE-001 (commit `7fbb57c`)

**File:** `src/main.rs` — `run_analyze()` doc-comment on `coverage_gaps`
param

**Before:** Stale scaffold comment described the parameter as a pre-ship
stub wired to `false`
from main() pending STORY-154.

**After:** Comment now accurately describes the shipped behavior — the
param activates the
per-packet UDP gap counter and appends `CoverageGapsSummary` output
(AC-154-002/003/007;
ADR-012 Decision 9), wired via `*coverage_gaps` from `Commands::Analyze`
destructure.

---

### Finding 2: STORY-154-LOOKUP-ARP-DEADCLAUSE-001 (commit `0fdaa29`)

**File:** `src/main.rs` — `lookup_protocol_state()` match guard

**Removed:** `|| p.name == "ARP"` disjunct in the `Some(p) if ...`
guard.

**Proof of death:** The enclosing `find()` predicate filters on
`p.transport == catalog_transport` where `catalog_transport` is
`Transport::Tcp` or
`Transport::Udp` (from the packet's network layer). The ARP catalog
entry has
`transport = Transport::LinkLayer` and `canonical_ports = []`, so it can
never pass the
`find()` predicate and be returned as `Some(p)`. The `|| p.name ==
"ARP"` clause in the
match guard was therefore unreachable on all possible inputs. A proof
comment documents
this reasoning in-place.

---

### Finding 3: STORY-154-ALL-COVERAGEGAPS-TEST-001 (commit `abc048e`)

**File:** `tests/integration_tests.rs` — new test
`test_BC_2_12_023_all_with_coverage_gaps_combination()`

**Added:** Integration test covering the `analyze --all --coverage-gaps`
combination, which
was previously untested. Verifies (1) exit 0, (2) `CoverageGapsSummary`
section present,
(3) TCP/9600 row shows state `unknown`. The `--all` and
`--coverage-gaps` flags are
orthogonal (clap config); the test guards against any future clap
conflict or orthogonality
regression.

### Finding 4: STORY-152/154-WEAK-UNKNOWN-ASSERT-001 (commit `f90dfb8`)

**File:** `tests/integration_tests.rs` — 3 assertions tightened

**Before:** Three tests used `stdout.contains("unknown")` — a substring
match that would pass
if "unknown" appeared anywhere in stdout for any reason.

**After:** Each assertion now uses a line-level check:
```rust
let tcp<port>_row_is_unknown = stdout
    .lines()
    .any(|l| l.contains("TCP/<port>") && l.ends_with("unknown"));
```
This ties the port identity to the state value, preventing false passes
from incidental
"unknown" substrings in error messages, headers, or other output rows.
Applies to:
- TCP/9600 state check (BC-2.12.024 PC-4)
- TCP/47808 state check (BC-2.12.024 EC-009 — BACnet/IP transport
mismatch)
- TCP/53 state check (BC-2.12.024 EC-010 / STORY-154-DNS53-TCP-GAP-001)

## Holdout Evaluation

N/A — evaluated at wave gate. No new behavioral contracts introduced.

## Adversarial Review

These 4 findings originate from the F5 scoped-adversarial review pass
(Phase F5).
All are LOW severity / non-blocking. This PR resolves them before the F6
formal-hardening phase.

## Security Review

**Verdict: APPROVE — no findings**

```mermaid
graph LR
    Critical["Critical: 0"]
    High["High: 0"]
    Medium["Medium: 0"]
    Low["Low: 0"]

```

OWASP Top 10 sweep: all N/A. Diff touches only internal match-guard
logic and tests;
no new input paths, no auth/authz, no dependencies, no network, no
serialization.
ARP dead-code removal is structurally sound — `find()` predicate
eliminates
`Transport::LinkLayer` entries before the removed disjunct could be
evaluated.
Test assertion tightening improves coverage properties; no security
checks weakened.

## Risk Assessment

### Blast Radius
- **Systems affected:** None (internal-only changes)
- **User impact:** None (no behavior change; doc-comment + dead-code +
test hardening)
- **Data impact:** None
- **Risk Level:** LOW

### Performance Impact

No performance impact. The removed ARP disjunct was dead code in a match
guard; its removal
has no runtime effect. No new hot paths introduced.

### Feature Flags

None. No feature flags used or required.
