Phase 7: Custom Rules and Print-Config Verification Report

Phase Goal: Users can define their own traffic classification rules in TOML, assign custom sounds to them, and inspect the full effective config before capture begins Verified: 2026-03-26T21:10:00Z Status: passed Re-verification: No — initial verification

Goal Achievement

Observable Truths

#	Truth	Status	Evidence
1	TOML [[rules]] blocks parse into classify.Rule slices	VERIFIED	convertRules() in config.go:192-206; TestLoadCustomRules passes; TestLoadCustomRuleNoPort passes
2	Missing protocol or class in a rule produces a clear error at startup	VERIFIED	validateRules() in config.go:175-189; TestLoadCustomRuleMissingProtocol, TestLoadCustomRuleMissingClass, TestLoadCustomRuleInvalidProtocol all pass
3	User rules are returned separately from FreqCfgs for caller to prepend	VERIFIED	LoadResult.UserRules []classify.Rule field in config.go:48-52; TestUserRulesPrepend passes
4	New class names without explicit sound config get auto-assigned frequencies in 1200-2400 Hz range	VERIFIED	autoAssignFreq() in config.go:210-219 uses FNV-32a; range [1200, 2350]; TestAutoFreqAssignment and TestAutoFreqDeterministic pass
5	Built-in class names in user rules do not get overwritten by auto-freq	VERIFIED	addAutoFreqEntries() checks if _, exists := cfgs[rule.Class]; !exists before assigning; TestAutoFreqSkipsBuiltins verifies HTTPS stays at 175.0 Hz
6	User runs netsynth --print-config and sees full effective config as commented TOML on stdout without capture starting	VERIFIED	runPrintConfig() in main.go:114-122; if printConfig check at main.go:73 fires before interface-required validation; TestPrintConfigNoInterface passes
7	User rules prepend before built-in rules so first-match-wins gives user priority	VERIFIED	append(result.UserRules, classify.DefaultRules...) in both runLiveMode (main.go:139) and runPcapMode (main.go:205); TestUserRulesPrepend confirms prepend order
8	Print-config output shows source path when config file loaded	VERIFIED	PrintConfig() emits # Config source: <path> when result.ConfigPath != ""; TestPrintConfigSourcePath passes
9	Print-config output annotates defaults vs overrides vs auto-assigned	VERIFIED	classAnnotation() in config.go:340-353 returns "default", "override", or "auto-assigned"; TestPrintConfigDefaultAnnotation, TestPrintConfigOverrideAnnotation, TestPrintConfigAutoAssignedAnnotation all pass
10	Print-config output includes [[rules]] section when user rules are present	VERIFIED	PrintConfig() emits [[rules]] section when len(result.UserRules) > 0 (config.go:284-295); TestPrintConfigContainsRules passes

Score: 10/10 truths verified

Key Link Verification

From	To	Via	Status	Details
config/config.go	classify/rules.go	convertRules produces []classify.Rule	WIRED	classify.Rule used at lines 49, 78, 192-206, 225 — manual grep confirmed
config/config.go	synth/config.go	autoAssignFreq creates FreqConfig entries with WaveformPresetHarmonics	WIRED	synth.WaveformPresetHarmonics called at lines 232, 384, 390 — manual grep confirmed
cmd/netsynth/main.go	config/config.go	runPrintConfig calls config.Load then config.PrintConfig	WIRED	config.PrintConfig(result) at main.go:119 — manual grep confirmed
cmd/netsynth/main.go	classify/rules.go	append(result.UserRules, classify.DefaultRules...)	WIRED	gsd-tools verified; pattern present at main.go:139 and main.go:205

Note: gsd-tools key-link checker reported false negatives for the three pattern matches involving escaped dots (\.). All four links are confirmed present via manual grep.

Data-Flow Trace (Level 4)

Artifact	Data Variable	Source	Produces Real Data	Status
config/config.go PrintConfig	result.UserRules, result.FreqCfgs, result.AutoClasses	config.Load() parsing TOML + FNV-32a hash	Yes — real TOML parsing, classify.Rule slices, synth.FreqConfig map	FLOWING
cmd/netsynth/main.go runLiveMode	allRules via result.UserRules	config.Load() -> convertRules() -> user TOML	Yes — user rules prepended to classify.DefaultRules	FLOWING
cmd/netsynth/main.go runPcapMode	allRules via result.UserRules	config.Load() -> convertRules() -> user TOML	Yes — same prepend pattern as runLiveMode	FLOWING

Behavioral Spot-Checks

Behavior	Command	Result	Status
config package: all 29 tests pass	go test ./config/... -count=1	ok (0.017s)	PASS
cmd/netsynth package: all 13 tests pass	go test ./cmd/netsynth/... -count=1	ok (0.013s)	PASS
Full test suite: all 7 packages	go test ./... -count=1	ok all 7 packages	PASS
Static analysis	go vet ./...	no issues	PASS
PrintConfig includes all 14 class names	TestPrintConfigContainsAllClasses	PASS	PASS
--print-config works without -i	TestPrintConfigNoInterface	PASS	PASS

Requirements Coverage

Requirement	Source Plan	Description	Status	Evidence
RULE-01	07-01	User can define custom classification rules in TOML (match by port and/or protocol, assign class name)	SATISFIED	RawRule struct + rawConfig.Rules []RawRule + TOML [[rules]] parsing; TestLoadCustomRules and TestLoadCustomRuleNoPort verify parsing
RULE-02	07-01, 07-02	User-defined rules take priority over built-in rules (prepend before defaults)	SATISFIED	append(result.UserRules, classify.DefaultRules...) in both runLiveMode and runPcapMode; TestUserRulesPrepend verifies order
RULE-03	07-01	User-defined class names automatically get a synthesis layer (no silent gaps)	SATISFIED	addAutoFreqEntries() creates FreqConfig for unknown class names using FNV-32a in [1200, 2350] Hz; TestAutoFreqAssignment verifies entry exists with WaveformSine
CFG-06	07-02	User can run netsynth --print-config to see the effective config as commented TOML	SATISFIED	--print-config flag registered; runPrintConfig() calls config.Load + config.PrintConfig + fmt.Print; fires before interface-required check; TestPrintConfigNoInterface confirms no -i needed

Orphaned requirements: None. All four requirement IDs (RULE-01, RULE-02, RULE-03, CFG-06) are claimed by plan frontmatter and verified above. REQUIREMENTS.md traceability table confirms all four map to Phase 7.

Anti-Patterns Found

File	Line	Pattern	Severity	Impact
(none)	—	—	—	—

No TODOs, FIXMEs, placeholder comments, empty return stubs, or hardcoded empty data found in modified files. The merge() function at config.go:368 does contain return defaults but returns the populated map after in-place mutation — this is correct behavior, not a stub.

Human Verification Required

The following behaviors cannot be verified programmatically and require manual testing before production use:

1. End-to-End TOML Round-Trip

Test: Create a netsynth.toml with multiple [[rules]] blocks (different ports, protocols, class names), run netsynth --print-config, copy the output to a new file, and load it again with --print-config --config <copied-file>. Expected: Output from both invocations should show the same class frequencies and annotations. Why human: Requires file creation, CLI invocation, and comparison of two output streams — not suitable for automated spot-check in a non-interactive environment.

2. Custom Rule Sound Differentiation

Test: Create a TOML defining a custom rule for port 8080/tcp as "WebApp", run a capture or play a pcap with HTTP traffic on port 8080, and listen to the resulting MP3. Expected: Port 8080 traffic should produce a distinct tone from port 80 (HTTP) traffic. Why human: Requires audio playback and subjective listening — cannot be verified programmatically.

Gaps Summary

No gaps. All 10 observable truths are verified, all 4 artifacts pass all three levels (exists, substantive, wired), all 4 key links are confirmed present in the code, all 4 requirements are satisfied, and the full test suite (7 packages, 29+ config tests, 13 main tests) passes cleanly.
