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.
