Phase 9: Frequency Design and Group Architecture Verification Report
Phase Goal: A complete, documented frequency allocation table for all ~35 traffic classes exists and the FreqConfig struct carries a Group field — design decisions are locked in before any protocol code is written Verified: 2026-03-27 Status: passed Re-verification: No — initial verification
Goal Achievement
Observable Truths (from ROADMAP.md Success Criteria)
| # | Truth | Status | Evidence |
|---|---|---|---|
| 1 | A written frequency allocation table lists every built-in class, its Hz value, waveform, and group — no class is TBD | VERIFIED | 32-slot table comment in synth/config.go lines 74-110; all 14 existing classes have concrete Hz/waveform/group; Phase 10 slots marked (Phase 10) in comments only |
| 2 | Every within-family pair satisfies at least a major second interval (ratio >= 1.122) | VERIFIED | Computed ratios: ICMP->NTP=1.1231, NTP->DHCP=1.1233, DHCP->DNS=1.6220, HTTPS->HTTP=1.1267, Unknown1->2=1.1232, 2->3=1.1224, 3->4=1.1224, 4->OtherTCP=1.1228, OtherTCP->OtherUDP=1.1224 — all pass |
| 3 | autoAssignFreq base for user-defined custom classes is set above all built-in frequencies, with no collision possible |
VERIFIED | baseHz = 2500.0, numSteps = uint32(31), stepHz = 50.0 in config/config.go:214-216; range [2500, 4000] is 51 Hz above the highest built-in slot at 2449 Hz |
| 4 | FreqConfig has a Group string field and all existing ClassFreqConfigs entries compile with the new struct shape |
VERIFIED | Group string field at synth/config.go:71; grep -c 'Group:' synth/config.go = 14; go test ./... passes all 7 packages |
Score: 4/4 truths verified
Required Artifacts
| Artifact | Expected | Status | Details |
|---|---|---|---|
synth/config.go |
FreqConfig with Group field, rebalanced ClassFreqConfigs, frequency allocation table comment | VERIFIED | Group string field exists; 32-slot allocation table present; all 14 entries populated with Phase 9 Hz values, family waveforms, and Group strings |
synth/config_test.go |
TestGroupFieldPopulated, updated TestHarmonicsNonEmpty | VERIFIED | TestGroupFieldPopulated at line 63; len(cfg.Harmonics) < 1 threshold at line 42 |
config/config.go |
Updated autoAssignFreq with baseHz=2500.0, numSteps=31 | VERIFIED | baseHz = 2500.0 at line 214; numSteps = uint32(31) at line 216; comment updated to [2500, 4000] |
config/config_test.go |
Updated range assertion to [2500, 4000] | VERIFIED | `cfg.BaseHz < 2500.0 |
Key Link Verification
| From | To | Via | Status | Details |
|---|---|---|---|---|
synth/config.go |
classify/types.go |
ClassFreqConfigs map keys reference classify.TrafficClass constants |
VERIFIED | All 14 map keys use classify.ClassICMP, classify.ClassDNS, etc. — confirmed by go build success and test run |
config/config.go |
synth/config.go |
addAutoFreqEntries creates synth.FreqConfig entries |
VERIFIED | synth.FreqConfig{...} literal in addAutoFreqEntries at line 228-233; TestAutoFreqAssignment passes |
Data-Flow Trace (Level 4)
Not applicable. Phase 9 produces configuration data (Go structs and constants), not UI/rendering components. The data flow is compile-time: ClassFreqConfigs map is a package-level var consumed at runtime by config.Load() and synth.NewBank(). Both consumers compile and their tests pass, confirming integration.
Behavioral Spot-Checks
| Behavior | Command | Result | Status |
|---|---|---|---|
| All synth tests pass including TestGroupFieldPopulated | go test ./synth/... -count=1 |
42 tests PASS | PASS |
| All config tests pass including TestAutoFreqAssignment | go test ./config/... -count=1 |
PASS | PASS |
| Full suite compiles and passes | go test ./... -count=1 |
7 packages, all PASS | PASS |
| autoAssignFreq math correct: 2500 + 30*50 = 4000 | Calculated | 4000.0 | PASS |
| All 14 ClassFreqConfigs entries have non-empty Group | grep -c 'Group:' synth/config.go |
14 | PASS |
| Within-family ratios all >= 1.122 | Computed from Hz values | Min ratio = 1.1224 | PASS |
Requirements Coverage
| Requirement | Source Plan | Description | Status | Evidence |
|---|---|---|---|---|
| FREQ-01 | 09-01 | All traffic classes redistributed into group-coherent frequency bands using musical interval ratios | SATISFIED | 14 existing classes redistributed to major-second ladder bands: Infrastructure 65-133 Hz, Web 150-169 Hz, Mail 214 Hz, Remote Access 343 Hz, Unknown 771-1375 Hz. REQUIREMENTS.md status shows "Pending" but is a stale tracking artifact — implementation is complete. |
| FREQ-02 | 09-01 | Within-family protocols separated by at least a major second interval (ratio 1.122) | SATISFIED | All computed within-family ratios pass: min observed 1.1224. REQUIREMENTS.md shows "Pending" — stale. |
| FREQ-03 | 09-01 | Full frequency allocation table designed and documented before FreqConfig code is written | SATISFIED | 32-slot table in synth/config.go lines 74-110 documents Hz, class, group, waveform, pan for every built-in slot including Phase 10 placeholders. REQUIREMENTS.md shows "Pending" — stale. |
| FREQ-04 | 09-02 | Auto-assign range updated to avoid collision with new built-in frequencies | SATISFIED | baseHz = 2500.0, numSteps = 31; REQUIREMENTS.md correctly marks this as "Complete". |
| GRP-01 | 09-01 | Each traffic class belongs to a named group | SATISFIED (for existing 14 classes) | All 14 ClassFreqConfigs entries have non-empty Group values (4 Infrastructure, 2 Web, 1 Mail, 1 Remote Access, 6 Unknown). Full satisfaction of groups including File Transfer, Database, Discovery, VoIP requires Phase 10 classes. REQUIREMENTS.md shows "Pending" — stale for partial; fully correct for Phase 10 expectation. |
| GRP-04 | 09-01 | FreqConfig gains a Group field that drives group-aware frequency allocation and config output |
SATISFIED | Group string field at synth/config.go:71; field is populated for all 14 entries; TestGroupFieldPopulated enforces this contract. REQUIREMENTS.md shows "Pending" — stale. |
Requirements Status Note
REQUIREMENTS.md shows FREQ-01, FREQ-02, FREQ-03, GRP-01, GRP-04 as "Pending" and FREQ-04 as "Complete". The "Pending" status is a stale tracking artifact — ROADMAP.md also shows plan 09-01 checkbox as [ ] rather than [x] despite three commits (eb36587, 2ef180b, fe7ee0e) fully executing the plan. The code, tests, and commit history confirm all requirements are implemented. REQUIREMENTS.md and the ROADMAP.md plan checkbox for 09-01 need updating.
Orphaned Requirements
None. All requirement IDs declared in the phase (FREQ-01 through FREQ-04, GRP-01, GRP-04) are accounted for above.
Anti-Patterns Found
| File | Line | Pattern | Severity | Impact |
|---|---|---|---|---|
| None | — | — | — | — |
No TODO/FIXME/placeholder comments found in modified files. No empty implementations or hardcoded empty data in rendered paths. Unknown-family entries use hand-tuned []HarmonicDef{{1,1.0},{2,0.8},{3,0.4}} by design (not a stub — WaveformType is intentionally WaveformCustom per D-05/D-06).
Human Verification Required
None. Phase 9 produces data structures and constants with no UI, audio playback, or external service dependencies. All behaviors are fully verifiable via compile + test.
Gaps Summary
No gaps. All 4 success criteria are verified against the actual codebase. The frequency allocation table exists as a code comment covering all 32 designed slots. The FreqConfig struct has the Group field. All 14 existing ClassFreqConfigs entries carry correct Hz values on the major-second ladder, family-matched waveforms, and non-empty Group strings. The autoAssignFreq range is [2500, 4000] Hz with a 51 Hz buffer above the highest built-in slot. All 7 packages compile and their full test suites pass.
Tracking artifact to fix: REQUIREMENTS.md should mark FREQ-01, FREQ-02, FREQ-03, GRP-01, GRP-04 as "Complete". ROADMAP.md should mark 09-01-PLAN.md as [x] and change "1/2 plans executed" to "2/2 plans executed".
