chore: archive v1.2 milestone — Extended Protocol Coverage

35 traffic classes across 9 protocol families shipped. Archives ROADMAP, REQUIREMENTS, and phase directories to milestones/v1.2-*. Updates README with new protocol families, sound design table, and [groups] TOML config documentation. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

+# Phase 9 Plan 2: Auto-Assign Frequency Range Update Summary
+
+Update autoAssignFreq to use [2500, 4000] Hz with 31 steps of 50 Hz, ensuring no collision with any built-in frequency (max 2449 Hz after Phase 9 Plan 1 rebalancing).
+
+## What Was Built
+
+Updated the `autoAssignFreq` function constants and corresponding test assertions so user-defined traffic classes are always assigned frequencies in the [2500, 4000] Hz range, safely above all built-in protocol frequencies.
+
+## Tasks Completed
+
+| Task | Name | Commit | Files |
+|------|------|--------|-------|
+| 1 | Update autoAssignFreq constants and comment | 8ae1ddc | config/config.go |
+| 2 | Update config_test.go auto-assign range assertion | dbcbeb3 | config/config_test.go |
+
+## Changes Made
+
+### Task 1: config/config.go
+
+- Changed `baseHz` constant from `1200.0` to `2500.0`
+- Changed `numSteps` from `uint32(24)` to `uint32(31)` (covers [2500, 4000] in 50 Hz steps: 2500 + 30*50 = 4000)
+- Updated function comment from `[1200, 2350]` to `[2500, 4000]`
+- `stepHz = 50.0` unchanged
+
+### Task 2: config/config_test.go
+
+- Updated `TestAutoFreqAssignment` comment from `[1200, 2350]` to `[2500, 4000]`
+- Updated range bounds assertion from `< 1200.0 || > 2350.0` to `< 2500.0 || > 4000.0`
+- Updated `TestAutoFreqSkipsBuiltins` HTTPS expected value from `175.0` to `150.0` (coordinated with Plan 01 HTTPS rebalancing)
+
+## Verification Results
+
+- `go build ./config/...` exits 0
+- `TestAutoFreqAssignment` passes
+- `TestAutoFreqDeterministic` passes
+- `TestAutoFreqSkipsBuiltins` will pass once Plan 01 updates HTTPS BaseHz to 150.0
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Known Stubs
+
+None.
+
+## Self-Check: PASSED
