# Phase 11 Plan 01: Frequency Config Data Layer Summary

**One-liner:** Added 21 ClassFreqConfigs entries (mDNS through Syslog) and expanded AllClasses() to 35 with LDAP/Kerberos/Syslog, fixing all hardcoded count assertions across synth, config, and classify test files.

## What Was Built

### Task 1: Add 21 ClassFreqConfigs entries and update AllClasses()

**synth/config.go** — Added 21 new `FreqConfig` entries to `ClassFreqConfigs` map, organized by protocol family:

| Family | Classes | Hz Range | Waveform |
|--------|---------|----------|----------|
| Infrastructure additions | mDNS, SSDP, SNMP | 93-118 Hz | Triangle |
| Web addition | QUIC | 190 Hz | Sawtooth |
| Mail additions | IMAP, POP3, SMTP-sub | 241-305 Hz | Triangle |
| Remote Access additions | RDP, Telnet, VNC | 385-485 Hz | Square |
| File Transfer additions | FTP, SMB, TFTP | 545-687 Hz | Square |
| Database additions | MySQL, PostgreSQL, Redis, MongoDB | 1543-2182 Hz | Sawtooth |
| VoIP | SIP | 2449 Hz | Sine |
| Infrastructure auto-assigned | LDAP, Kerberos, Syslog | 2950-3250 Hz | Triangle |

All 21 entries use `WaveformPresetHarmonics()` per D-01. Total map: 35 entries.

**classify/types.go** — Updated `AllClasses()`:
- Added `ClassLDAP`, `ClassKerberos`, `ClassSyslog` to Infrastructure section (after ClassSNMP)
- Updated doc comment: removed Phase 11 exclusion note, now says "AllClasses returns all known traffic classes in display order."
- Now returns 35 entries (was 32)

### Task 2: Fix all hardcoded count assertions

| File | Change |
|------|--------|
| synth/bank_test.go | Renamed `TestNewBankHas14Layers` to `TestNewBankHasAllLayers`; `!= 14` → `!= len(classify.AllClasses())` |
| config/config_test.go | 4 occurrences of `!= 14` → `!= len(classify.AllClasses())`; TestPrintConfigContainsAllClasses: hardcoded 14-class list → `classify.AllClasses()` loop |
| classify/classifier_test.go | `want 32` → `want 35` in TestAllClassesCount |

## Verification Results

```
go test ./...
ok  github.com/netsynth/netsynth/aggregate
ok  github.com/netsynth/netsynth/capture
ok  github.com/netsynth/netsynth/classify
ok  github.com/netsynth/netsynth/cmd/netsynth
ok  github.com/netsynth/netsynth/config
ok  github.com/netsynth/netsynth/encode
ok  github.com/netsynth/netsynth/synth
```

All 7 packages pass.

## Commits

| Task | Commit | Description |
|------|--------|-------------|
| 1 | 1556ce8 | feat(11-01): add 21 ClassFreqConfigs entries and include LDAP/Kerberos/Syslog in AllClasses() |
| 2 | 35d8915 | fix(11-01): update hardcoded count assertions to reflect 35 traffic classes |

## Deviations from Plan

**1. [Rule 3 - Blocker] Worktree was at stale commit missing Phase 8-10 changes**
- **Found during:** Pre-execution setup
- **Issue:** Worktree branch `worktree-agent-af29ad97` was at commit `8e565ec` (milestone v1.2 roadmap docs), 43 commits behind `master`. The target files (synth/config.go, classify/types.go) were in their Phase 7 state.
- **Fix:** Ran `git merge master --no-edit` (fast-forward) to bring worktree to current HEAD `683470a`.
- **Files modified:** All files (fast-forward merge, no conflicts)
- **Commit:** Not a separate commit — prerequisite action before Task 1

## Known Stubs

None — all 35 ClassFreqConfigs entries have complete Hz, waveform, pan, and group values. No placeholder data.

## Self-Check: PASSED
