Two tools:
1. --debug-tap on relay: logs packet header metadata (seq, codec, ts,
FEC, repair, size) per room without decryption. 0.5 day effort.
2. wzp-analyzer standalone: joins room as observer, decodes audio,
shows TUI with per-participant waveforms + quality stats + FEC
recovery rates. Capture/replay and HTML reports. 5-8 days total.
