# Project State

## Project Reference

See: .planning/PROJECT.md (updated 2026-03-27)

**Core value:** Network traffic patterns are instantly recognizable as distinct sounds — a ping sounds different from HTTPS noise, which sounds different from a port scan.
**Current focus:** Phase 8 — Test and Constant Cleanup (v1.2 start)

## Current Position

Phase: 8 of 11 (Test and Constant Cleanup)
Plan: — (not yet planned)
Status: Ready to plan
Last activity: 2026-03-27 — v1.2 roadmap created, 4 phases defined (8-11), 18 requirements mapped

Progress: [░░░░░░░░░░] 0%

## Performance Metrics

**Velocity (v1.1 baseline):**

- Total plans completed: 6
- Average duration: ~3 min
- Total execution time: ~18 min

**By Phase (v1.1):**

| Phase | Plans | Total | Avg/Plan |
|-------|-------|-------|----------|
| 05 | 2 | ~7min | 3.5min |
| 06 | 2 | ~4min | 2min |
| 07 | 2 | ~6min | 3min |

**Recent Trend:** Stable

## Accumulated Context

### Decisions

- [v1.2 Roadmap]: Phase 8 before everything — stale NumLayers/GainPerLayer constant and hardcoded TestFrequenciesInRange bounds cause false CI failures throughout milestone if not removed first
- [v1.2 Roadmap]: Phase 9 is design-only (no protocol code) — Hz allocation must be locked before ClassFreqConfigs entries are written; retroactive rebalancing touches every entry
- [v1.2 Roadmap]: Phase 10 before Phase 11 — TrafficClass constants must exist before ClassFreqConfigs can reference them (three-location atomicity enforced by existing test)
- [v1.2 Roadmap]: GRP-02 and GRP-03 deferred to Phase 11 — PrintConfig group headers and TOML [groups] config depend on both Group field (Phase 9) and new class constants (Phase 10)
- [Phase 07]: addAutoFreqEntries runs before merge so [sounds.X] overrides apply to user-defined classes
- [Phase 07]: LoadResult struct chosen over tuple return for config.Load() — cleaner API contract

### Pending Todos

1 pending todo: `.planning/todos/pending/001-expand-traffic-classes.md`

### Blockers/Concerns

- [v1.2 pre-work]: autoAssignFreq range [1200, 2350] Hz will collide with new built-in frequencies unless pushed above all new entries (addressed in Phase 9 design)
- [v1.2 pre-work]: Frequency rebalancing may silently invalidate v1.1 user TOML configs with explicit Hz overrides — mitigation: assign all new protocols above 1047 Hz to leave existing layout frozen
