…eport (STORY-154)
Implements BC-2.12.023 v1.2 + BC-2.12.024 v1.1 (ADR-012 Decisions 2, 3a/3b, 8, 9).
## Changes
**src/cli.rs (AC-154-001)**
- Add `--coverage-gaps: bool` to `Analyze` subcommand; NOT in --all group
- Doc comment is user-facing only — no internal IDs (PG-HELP-PROVENANCE-CLI-DOC-001)
**src/main.rs (AC-154-002/003/004/005/006/007)**
- Wire `*coverage_gaps` from `Commands::Analyze { ..., coverage_gaps, ... }` destructure
- Apply `.with_coverage_gaps(coverage_gaps)` builder on `StreamDispatcher` (STORY-153 pattern)
- Hoist `dns_analyzer.can_decode()` to `classified_by_dns` binding (STORY-154-CAN-DECODE-HOIST-001 / F-W67-L3)
- Add `L2_CAVEAT_TEXT` constant (BC-2.12.024 Invariant 1/3; always present)
- Add `PORT_102_NOTE` constant (conditional on TCP/102 non-zero count; names all 4 protocols)
- Add `ProtocolGapState` enum: KnownUnsupported / Unknown / KnownSupported (ADR-012 Decision 2)
- Implement `lookup_protocol_state()`: transport-aware KNOWN_PROTOCOLS catalog lookup;
supportedness derived from canonical_ports ∩ SUPPORTED_PORTS (BC-2.18.003 / AC-151-005)
- Add `collect_all_gaps()`: merges TCP + UDP gap maps
- Add `render_coverage_gaps_terminal()`: appended AFTER Findings (ADR-012 Decision 9);
always includes L2 caveat; per-entry tri-state; PORT_102_NOTE adjacent to TCP/102
- Add `inject_coverage_gaps_json()`: adds "coverage_gaps" object to JSON output
(schema: caveat_l2 + entries[{transport,port,count,state,name?,collision_note?}])
- Gate both renderers on `coverage_gaps` flag; CSV path unchanged
**tests/integration_tests.rs (AC-154-001 through AC-154-008)**
- Update 6 tests with crafted fixtures and --http flag (TCP reassembly + analyzer-present guard)
**tests/fixtures/ (F4-FIXTURE-NEED-001)**
- gap-tcp102.pcap (94B): single TCP SYN → port 102 (S7comm/MMS collision port)
- gap-udp47808.pcap (82B): single UDP datagram → port 47808 (BACnet/IP known-unsupported)
- gap-tcp47808.pcap (94B): single TCP SYN → port 47808 (transport mismatch → unknown)
- gap-tcp9600.pcap (94B): single TCP SYN → port 9600 (no catalog match → unknown)
- gap-tcp53.pcap (94B): single TCP SYN → port 53 (DNS UDP-only → TCP/53 unknown)
## Test Results
- 20 story_154 tests (16 integration + 4 unit): ALL PASS
- Full regression: cargo test --all-targets — all pass (zero failures)
- cargo clippy --all-targets -- -D warnings: clean
- cargo fmt --check: clean
## Architecture Compliance
- --coverage-gaps NOT in --all group (BC-2.12.023 Invariant 1)
- CoverageGapsSummary is additive named section, NEVER Finding structs (ADR-012 Decision 9)
- analyze without --coverage-gaps: output byte-identical to pre-feature behavior (AC-154-003)
- L2_CAVEAT_TEXT always present (BC-2.12.024 Invariant 1)
- PORT_102_NOTE conditional on (Tcp,102) count > 0 (BC-2.12.024 Invariant 2)
- JSON object form { caveat_l2, entries } NOT flat dict (BC-2.12.023 PC-3 v1.2 corrected form)
- TCP/102: omit name field, use collision_note (BC-2.12.024 PC-5 / DF-CANONICAL-FRAME-HOLDOUT-001)
- BACnet/IP (Udp,47808) → known-unsupported (DF-CANONICAL-FRAME-HOLDOUT-001)
- (Tcp,47808) → unknown (transport mismatch; BC-2.12.024 EC-009)
… sweep HIGH-1 (DF-KANI-NONVACUITY-001): test_BC_2_12_024_tcp_502_absent_from_gap_report now passes --modbus so the TcpReassembler IS built and classify() actually runs on the TCP/502 flow. Rule-5 routes port-502 → DispatchTarget::Modbus (not None) → absence of 502 in the gap report is now non-vacuous. If Rule 5 regressed, this test fails. MEDIUM-1: test_BC_2_12_023_coverage_gaps_counts_unclassified now uses GAP_TCP9600_FIXTURE with --http instead of http-ooo.pcap without an analyzer. Adds assertion that at least one gap entry (count=) is present, satisfying AC-154-002 ≥1 entry. LOW-1: test_BC_2_12_024_port102_footnote_absent_without_tcp102 now uses GAP_TCP9600_FIXTURE with --http. Anchors the absence assertion with a non-vacuous presence check: TCP/9600 entry (count=) must appear first, proving gap machinery is active before asserting PORT_102_NOTE strings are absent. SIBLING-SWEEP (DF-SIBLING-SWEEP-001): All story_154 TCP-gap tests audited. Every test asserting a TCP gap entry (port102, tcp47808, tcp9600, tcp53) already had --http; the two tests newly fixed above (502-absent, port102-absent) now also have an analyzer flag. UDP test (bacnet/47808) correctly has no analyzer flag (decode-loop path). HIGH-2 (DF-GREEN-DOC-TENSE-SWEEP): Swept all RED-GATE / todo!() / "until GREEN" / "passes before implementation" language in src/main.rs and tests/integration_tests.rs STORY-154 code. Before: 27 matching lines. After: 0 matching lines. All doc comments rewritten to present-tense GREEN regression guard language. No fixture changes required; no new internal CLI help IDs added.
…itive coverage MEDIUM-1 (BC-2.12.024 PC-5 / AC-154-007): - test_BC_2_12_024_json_entry_bacnet_schema: assert (UDP,47808) entry has transport=="UDP", port==47808 as integer, count>=1, state=="known-unsupported", name=="BACnet/IP", no collision_note field (non-vacuous: fails if name omitted or state wrong) - test_BC_2_12_024_json_entry_port102_collision_note: assert (TCP,102) entry has state=="known-unsupported", collision_note names S7comm/IEC 61850 MMS/ICCP, no name field - test_BC_2_12_024_json_entry_unknown_state: assert (TCP,9600) entry has state=="unknown", no name field LOW-1 (EC-154-4 / EC-154-7): - test_BC_2_12_024_empty_entries_message: assert empty-state message "No unclassified port gaps detected." and L2 caveat both present when analyze finds no unclassified gaps LOW-2 (AC-154-003 / AC-154-008 / Architecture Compliance Rule 3): - test_BC_2_12_023_coverage_gaps_purely_additive: assert stdout(--http) is byte-identical prefix of stdout(--http --coverage-gaps); proves the section is purely appended, no prior output mutated DF-SIBLING-SWEEP-001: test_BC_2_12_023_json_coverage_gaps_key only checks the top-level "coverage_gaps" key exists — could be strengthened to verify entries/caveat_l2 fields. Noted; not changed (new dedicated tests cover schema).

…ad-code, test hardening (#356) ## Fix: F6 Pre-Hardening Cleanup — 4 LOW/non-blocking F5 adversarial findings **Source:** Phase F5 scoped-adversarial review (feature-protocol-coverage / E-21) **Phase:** F6 pre-hardening cleanup **Severity:** LOW (all 4 findings non-blocking) **Stories:** STORY-152, STORY-153, STORY-154 **Mode:** feature (fix-PR delivery — no demo recording; no user-facing behavior change)    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. --- ## Architecture Changes ```mermaid graph TD main["src/main.rs"] tests["tests/integration_tests.rs"] doc_fix["doc-comment corrected\n(STORY-153-RUNANALYZE-DOC-STALE-001)"] dead_code["ARP dead clause removed\n(STORY-154-LOOKUP-ARP-DEADCLAUSE-001)"] new_test["new combined --all --coverage-gaps test\n(STORY-154-ALL-COVERAGEGAPS-TEST-001)"] tightened["3 weak assertions tightened\n(STORY-152/154-WEAK-UNKNOWN-ASSERT-001)"] main --> doc_fix main --> dead_code tests --> new_test tests --> tightened style doc_fix fill:#87CEEB style dead_code fill:#87CEEB style new_test fill:#90EE90 style tightened fill:#90EE90 ``` No architecture changes. All edits are cosmetic (doc-comment), provably-dead-code removal, and test hardening within existing modules. --- ## Story Dependencies ```mermaid graph LR S152["STORY-152\n✅ merged #353"] --> FIX["fix/f6-hardening-cleanup\n🔨 this PR"] S153["STORY-153\n✅ merged #352"] --> FIX S154["STORY-154\n✅ merged #355"] --> FIX style FIX fill:#FFD700 ``` All upstream stories are already merged into `develop`.

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) --- ## Test Evidence | Metric | Value | Status | |--------|-------|--------| | Full test suite | 85 binaries, 0 failures | PASS | | New tests added | 1 (STORY-154-ALL-COVERAGEGAPS-TEST-001) | PASS | | Modified assertions | 3 tightened (STORY-152/154-WEAK-UNKNOWN-ASSERT-001) | PASS | | `cargo clippy --all-targets -- -D warnings` | Clean | PASS | | `cargo fmt --check` | Clean | PASS | ### New Test | Test | BC | Result | |------|----|--------| | `test_BC_2_12_023_all_with_coverage_gaps_combination()` | BC-2.12.023 Invariant 1, PC-1 | PASS | --- ## 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. | Finding ID | Category | Severity | Resolution | |------------|----------|----------|------------| | STORY-153-RUNANALYZE-DOC-STALE-001 | docs/comment accuracy | LOW | Doc-comment corrected | | STORY-154-LOOKUP-ARP-DEADCLAUSE-001 | dead code | LOW | ARP disjunct removed + proof comment | | STORY-154-ALL-COVERAGEGAPS-TEST-001 | test coverage gap | LOW | New integration test added | | STORY-152/154-WEAK-UNKNOWN-ASSERT-001 | test quality | LOW | 3 assertions tightened | --- ## Security Review **Verdict: APPROVE — no findings** ```mermaid graph LR Critical["Critical: 0"] High["High: 0"] Medium["Medium: 0"] Low["Low: 0"] style Critical fill:#90EE90 style High fill:#90EE90 style Medium fill:#90EE90 style Low fill:#90EE90 ``` 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. --- ## Traceability | Finding | BC | Commit | File | Status | |---------|----|----|------|--------| | STORY-153-RUNANALYZE-DOC-STALE-001 | BC-2.05.010 | `7fbb57c` | `src/main.rs:193` | RESOLVED | | STORY-154-LOOKUP-ARP-DEADCLAUSE-001 | BC-2.12.023 | `0fdaa29` | `src/main.rs:1063` | RESOLVED | | STORY-154-ALL-COVERAGEGAPS-TEST-001 | BC-2.12.023 Inv.1/PC-1 | `abc048e` | `tests/integration_tests.rs` | RESOLVED | | STORY-152/154-WEAK-UNKNOWN-ASSERT-001 | BC-2.12.024 PC-4/EC-009/EC-010 | `f90dfb8` | `tests/integration_tests.rs` | RESOLVED | --- ## AI Pipeline Metadata <details> <summary><strong>Pipeline Details</strong></summary> ```yaml ai-generated: true pipeline-mode: feature factory-version: "1.0.0-rc.21" pipeline-stages: fix-pr-delivery: in-progress demo-recording: skipped (no behavior change) wave-integration-gate: skipped (fix PR — merges individually) fix-source: F5 scoped-adversarial review (E-21 feature-protocol-coverage) findings-resolved: 4 findings-severity: LOW models-used: pr-manager: claude-sonnet-4-6 security-reviewer: dispatched pr-reviewer: dispatched generated-at: "2026-07-04T00:00:00Z" ``` </details> --- ## Pre-Merge Checklist - [ ] All CI status checks passing - [x] No restricted files changed (only src/main.rs, tests/integration_tests.rs) - [x] No behavior change — docs/dead-code/test-hardening only - [x] All 4 F5 adversarial findings addressed - [ ] Security review: PENDING - [ ] PR reviewer: PENDING - [x] No demo recording required (no user-observable behavior change) - [x] No wave integration gate (fix PR — merges individually per autonomy level 4)

BMC degenerates to a concrete execution already covered by the designated proptests. - Vec+&str modeling in CBMC was found **intractable**: a trial run exceeded 12 minutes without convergence. CBMC's string model incurs exponential blowup over string length for the 100+ catalog entries. - **Decision:** retain the designated proptests (already re-verified green at develop HEAD) as the proof obligation; document the Kani deferral inline in `src/protocols.rs` with full rationale. This matches the pattern used for VP-004 HashMap accumulation (documented inline in `src/dispatcher.rs`). ### Fuzz Target: `fuzz_coverage_gap_classify` The harness exercises three surfaces in a single run: 1. `classify_protocol(name)` exhaustiveness oracle (VP-041) 2. `CoverageGapDispatcher::on_data` + `on_flow_close` dual-gate paths (VP-042) 3. `udp_gap_key(src, dst, is_udp)` gate + key contract (VP-043) Run: 2,049,292 executions in 301s (~6,808 exec/s). 0 crashes, 0 OOM, 0 timeouts. No artifact written to `fuzz/artifacts/fuzz_coverage_gap_classify/`. ### Mutation Testing — E-21 Delta Scope: `--file src/protocols.rs --file src/dispatcher.rs --file src/main.rs` (delta functions only). All 3 genuine survivors pinned by new tests: | Survivor | Location | Mutation | Killing Test | |----------|----------|----------|--------------| | `collect_all_gaps +=/*=` | `main.rs:1088` | `*=` zeroes TCP count | `f6_collect_all_gaps_preserves_tcp_count` | | `inject_coverage_gaps_json &&/\|\|` | `main.rs:1224` | `\|\|` short-circuits name preservation | `f6_inject_json_tcp_non102_name_no_collision` | | `on_flow_close guard \|\|/&&` | `dispatcher.rs:464` | `&&` eliminates EtherNet/IP or DNP3 disjunct | `f6_unclassified_counts_with_only_{enip,dnp3}_analyzer` | **Post-fix delta kill rate: 100% (34/34 viable delta mutants).** Remaining 2 survivors (`run_analyze` ReassemblyConfig field deletions in `main.rs`) are pre-existing, out-of-delta `main()` integration-glue — LOW-tier, not delta-introduced. </details> --- ## Holdout Evaluation N/A — evaluated at wave gate (mean satisfaction 1.00 at F4/E-21 holdout).

--coverage-gapsOpt-In Flag +CoverageGapsSummaryTri-State Report + Mandatory Caveats (BC-2.12.023 + BC-2.12.024)Epic: E-21 — feature-protocol-coverage (FINAL F4 story, Wave 69)
Mode: feature
Convergence: CONVERGED after 3 consecutive fresh-context adversarial passes on a5f8e52 (0 P0/CRITICAL/HIGH/mis-anchor)
This PR delivers the final story of the E-21 feature-protocol-coverage feature wave. It adds an
opt-in
--coverage-gapsCLI flag to theanalyzesubcommand that causes wirerust to track andreport unclassified TCP flows and UDP packets by (transport, port), presented as a
CoverageGapsSummarynamed section with tri-state classification(
known-unsupported/unknown/known-supported), a mandatory L2/multicast limitationcaveat that is always present, and a conditional port-102 collision footnote naming all four
protocols (S7comm, S7comm-plus, IEC 61850 MMS, ICCP/TASE.2) that share TCP/102 via
ISO-on-TCP/TPKT. The design is purely additive —
--coverage-gapsis independent of--all; all existingFindingentries andAnalysisSummaryoutput are unchanged.The PR diff is exactly 8 files:
src/cli.rs(+4),src/main.rs(+438),tests/integration_tests.rs(+827), and 5 crafted pcap fixtures in
tests/fixtures/required by the integration tests(these are legitimate committed test data, not demo artifacts).

ADR-012: Protocol Coverage Catalog — Coverage Gap Report Decisions
Decision 2 (Tri-state classification): Each gap entry is classified using a Suricata-derived vocabulary:
known-unsupported(catalog match but not dissected),unknown(no catalog match),known-supported(catalog match AND dissected — BUG signal). Classification is transport-aware:(Tcp, 47808)isunknowneven though BACnet/IP is catalogued, because BACnet isUdponly. LinkLayer entries never match port-keyed lookups.Decision 3a (L2 caveat): The L2/multicast caveat is always present — L2 protocols have no TCP/UDP port and are structurally absent from the gap report. The constant is not configurable.
Decision 3b (Port-102 footnote): The TCP/102 collision footnote (naming S7comm, S7comm-plus, IEC 61850 MMS, ICCP/TASE.2) is row-specific and conditional on a non-zero count for
(Tcp, 102).Decision 8 (
--coverage-gapsopt-in): The flag is NOT in the--allexpansion group. The two flags are independent.--allselects all analyzers;--coverage-gapsenables gap detection.Decision 9 (Named section after findings):
CoverageGapsSummaryis appended after allFindingentries. It is NOT aFindingitself (that would pollute the MITRE-severity pipeline with infrastructure data).Consequences:
classify()Rule 5 always routes TCP/502 toDispatchTarget::Modbus—(Tcp, 502)can never appear in the gap report via the analyze pipeline.known-supportedis assertable only at the pure-function/unit level.with_coverage_gaps(bool)builder (from STORY-153) preserves all existingStreamDispatcher::new()call sites with zero blast radius.Story Dependencies

Note on Test Fixtures
The 5 files in
tests/fixtures/gap-*.pcapare crafted minimal pcap files required by theintegration tests — they are legitimate committed test data, not demo artifacts:
gap-tcp102.pcap— minimal pcap with a TCP/102 flow (triggers port-102 footnote)gap-tcp47808.pcap— minimal pcap with a TCP/47808 flow (transport-mismatch → unknown)gap-tcp53.pcap— minimal pcap with a TCP/53 flow (DNS is UDP-only → unknown)gap-tcp9600.pcap— minimal pcap with a TCP/9600 flow (no catalog match → unknown)gap-udp47808.pcap— minimal pcap with a UDP/47808 flow (BACnet/IP → known-unsupported)Demo evidence (VHS GIF+WebM recordings) is at
