# Project State

## Project Reference

See: .planning/PROJECT.md (updated 2026-03-26)

**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 06 — config-package-and-sound-overrides

## Current Position

Phase: 06 (config-package-and-sound-overrides) — EXECUTING
Plan: 2 of 2
Status: Ready to execute
Last activity: 2026-03-26

Progress: [░░░░░░░░░░] 0%

## Performance Metrics

**Velocity (v1.0 baseline):**

- Total plans completed: 11
- Average duration: 7.7 min
- Total execution time: ~1.4 hours

**By Phase (v1.0):**

| Phase | Plans | Total | Avg/Plan |
|-------|-------|-------|----------|
| 01 | 4 | ~30min | 7.5min |
| 02 | 3 | ~28min | 9.3min |
| 03 | 2 | ~20min | 10min |
| 04 | 2 | ~7min | 3.5min |

**Recent Trend:** Stable
| Phase 05 P01 | 3min | 2 tasks | 3 files |
| Phase 05 P02 | 4 | 2 tasks | 4 files |
| Phase 06 P02 | 2 | 2 tasks | 3 files |

## Accumulated Context

### Decisions

- [v1.1 Roadmap]: Phase 5 consolidates waveform types (WAVE-01, WAVE-02) with bank decoupling — both are internal refactors with no user-visible surface, establishing the injectable seam before config is added
- [v1.1 Roadmap]: Research steps 5+6 (wire config + freq/waveform overrides) collapsed into Phase 6 — they share the same integration boundary (encode.RunSynthesis signature change) and are safer to land together
- [v1.1 Roadmap]: User class name collision with built-in TrafficClass strings is an unresolved design question — decide before coding Phase 7 (treat as override vs. reject as ambiguous)
- [Phase 05]: FreqConfig struct uses named field syntax for ClassFreqConfigs entries (required by WaveformType addition)
- [Phase 05]: WaveformType zero value is WaveformCustom — all 14 existing ClassFreqConfigs entries retain hand-tuned harmonics without modification
- [Phase 05]: NewBank accepts injected config map instead of reading ClassFreqConfigs global — injection seam for Phase 6 config loading
- [Phase 05]: gainPerLayer computed as 1.0/float64(len(cfgs)) — correct for any class count, no-clip guarantee preserved
- [Phase 06]: Option A for freqCfgs propagation: pass as parameter to runLiveMode/runPcapMode — cleaner data flow vs package-level var
- [Phase 06]: config.Load positioned after BPF validation, before output path resolution — ensures fail-fast before any I/O (D-11)

### Pending Todos

None.

### Blockers/Concerns

- [Phase 7 pre-work]: User-defined class names that collide with built-in class strings (e.g., `class = "HTTPS"`) require an explicit design decision before Phase 7 coding begins. Research flags this as unresolved. Options: treat as override (simplest) or reject as ambiguous. Resolve during Phase 7 planning.
