Phase 10: Classification Layer Verification Report

Phase Goal: All new protocol families are classified — ~21 new TrafficClass constants exist, AllClasses() covers them, and DefaultRules maps all new ports to their classes Verified: 2026-03-27 Status: passed Re-verification: No — initial verification

Goal Achievement

Observable Truths

#	Truth	Status	Evidence
1	21 new TrafficClass constants exist with correct string values per D-05	VERIFIED	35 total constants in types.go (14 existing + 21 new); all string values match spec
2	AllClasses() returns 32 classes (18 new + 14 existing, excluding LDAP/Kerberos/Syslog)	VERIFIED	TestAllClassesCount asserts 32 and passes; AllClasses() body verified
3	DefaultRules contains 30 new port-matching rules before the catch-alls per D-06	VERIFIED	42 total rules (12 existing + 30 new); last two are DstPort:0 catch-alls
4	Plain/TLS variants share a single class constant per D-03	VERIFIED	IMAP 143+993, POP3 110+995, FTP 20+21, LDAP 389+636 all map to single class
5	SMTP (port 25) and SMTP-sub (port 587) remain separate classes per D-04	VERIFIED	ClassSMTP="SMTP" and ClassSMTPSub="SMTP-sub" are distinct constants and rules
6	Every new protocol port tested and classifies to correct TrafficClass	VERIFIED	28 new subtests in TestClassify all PASS (go test ./classify/...)
7	All 10 existing protocol tests still pass unchanged (PROTO-09 regression)	VERIFIED	TestClassifyICMP, DNS, HTTPS, HTTP, SSH, SMTP, NTP, DHCP, OtherTCP, OtherUDP all PASS

Score: 7/7 truths verified

Required Artifacts

Artifact	Expected	Status	Details
classify/types.go	21 new TrafficClass constants, AllClasses()	VERIFIED	21 new constants present; AllClasses() returns 32 excluding LDAP/Kerberos/Syslog
classify/rules.go	30 new port-matching rules	VERIFIED	42 total rules; ClassMongoDB present; catch-alls are last two
classify/classifier_test.go	26+ subtests for new protocol combinations	VERIFIED	28 new subtests present (PROTO-06 SIP has 2 transport variants); ClassIMAP referenced

Key Link Verification

From	To	Via	Status	Details
classify/rules.go	classify/types.go	Rule.Class references TrafficClass constants	VERIFIED	Class:Class(IMAP
classify/classifier_test.go	classify/types.go	test assertions reference new constants	VERIFIED	classify.Class(IMAP
classify/classifier_test.go	classify/rules.go	NewClassifier(DefaultRules) uses updated rules	VERIFIED	classify.DefaultRules referenced in test setup

Data-Flow Trace (Level 4)

Not applicable — this phase adds classification constants, port rules, and tests only. No components rendering dynamic data.

Behavioral Spot-Checks

Behavior	Command	Result	Status
go test ./classify/... passes	go test ./classify/... -count=1	PASS	PASS
TestAllClassesCount expects 32	go test ./classify/... -run TestAllClassesCount	PASS	PASS
28 new subtests in TestClassify pass	go test ./classify/... -run TestClassify -v	All 43 subtests PASS	PASS
Package builds without errors	go build ./classify/...	exit 0	PASS

Full test run output (43 subtests, 3 test functions):

• TestClassify: 43 subtests (13 existing + 28 new + TestRulesAreOrderDependent), all PASS
• TestAllClassesCount: PASS (asserts len == 32)
• TestHashBucketDistribution: PASS

Requirements Coverage

Requirement	Source Plan	Description	Status	Evidence
PROTO-01	10-01, 10-02	Mail: IMAP (143/993), POP3 (110/995), SMTP-sub (587)	SATISFIED	Constants ClassIMAP, ClassPOP3, ClassSMTPSub; rules for all 5 ports; 5 test subtests all PASS
PROTO-02	10-01, 10-02	File Transfer: FTP (20-21), SMB (445), TFTP (69)	SATISFIED	Constants ClassFTP, ClassSMB, ClassTFTP; rules for all 4 ports; 4 test subtests all PASS
PROTO-03	10-01, 10-02	Remote Access: RDP (3389), Telnet (23), VNC (5900)	SATISFIED	Constants ClassRDP, ClassTelnet, ClassVNC; rules for all 3 ports; 3 test subtests all PASS
PROTO-04	10-01, 10-02	Database: MySQL (3306), PostgreSQL (5432), Redis (6379), MongoDB (27017)	SATISFIED	Constants and rules for all 4 databases; 4 test subtests all PASS
PROTO-05	10-01, 10-02	Discovery: mDNS (5353), SSDP (1900), SNMP (161-162)	SATISFIED	Constants ClassMDNS, ClassSSDP, ClassSNMP; rules for all 4 ports; 4 test subtests all PASS
PROTO-06	10-01, 10-02	VoIP: SIP (5060/5061) on TCP and UDP	SATISFIED	ClassSIP constant; 4 rules (TCP+UDP x 5060+5061); TestClassifySIP_TCP5060 and TestClassifySIP_UDP5060 both PASS
PROTO-07	10-01, 10-02	Web extension: QUIC/HTTP3 (UDP 443)	SATISFIED	ClassQUIC constant; udp/443 rule before tcp/443 rule; TestClassifyQUIC_UDP443 PASS (not matched as HTTPS)
PROTO-08	10-01, 10-02	Infrastructure: LDAP (389/636), Kerberos (88), Syslog (514)	SATISFIED	Constants ClassLDAP, ClassKerberos, ClassSyslog; 5 rules; 5 test subtests all PASS; correctly excluded from AllClasses() per D-01
PROTO-09	10-02	Existing 10 protocols unchanged — no regression	SATISFIED	TestClassifyICMP, DNS_UDP, DNS_TCP, HTTPS, HTTP, SSH, SMTP, NTP, DHCP_port67, DHCP_port68, OtherTCP, OtherUDP all PASS

All 9 requirements from phase 10 plans are satisfied. No orphaned requirements found — REQUIREMENTS.md traceability table maps PROTO-01 through PROTO-09 to Phase 10 and marks all as Complete.

Anti-Patterns Found

File	Line	Pattern	Severity	Impact
(none)	—	—	—	No TODO, FIXME, placeholder, or stub patterns found in classify/types.go, classify/rules.go, or classify/classifier_test.go

Human Verification Required

None. All phase 10 behaviors are programmatically verifiable through unit tests.

Gaps Summary

No gaps. All 7 observable truths verified, all 3 artifacts substantive and wired, all 9 requirements satisfied, go test ./classify/... passes with 0 failures.

Note on expected synth package failures: go test ./synth/... is intentionally not the phase gate. Tests TestAllClassesHaveConfig, TestNewBankHas14Layers, TestLoadAllDefaultsPresent, and TestClassFreqConfigsMatchAllClasses are expected to fail after Phase 10 because AllClasses() now returns 32 entries but ClassFreqConfigs has 14 entries. This is documented in research and will be resolved in Phase 11 when ClassFreqConfigs entries for the 18 new classes are added.
