# Ideator Wave 10 — Sept 19, 2026 (Cell Communication)

**5 communication ideas**: speak, write, listen, shout, whisper.

## 1. quilt-cell-speak — Speaking
- Schema: `voice`, `last_words`, `speaks_to`
- Cell calls TTS to communicate
- Other cells witness the audio
- **The substrate has a voice.**

## 2. quilt-cell-write — Writing
- Schema: `letter_to`, `letter_body`, `letter_signed`
- Letters are cells too
- **The substrate has mail.**

## 3. quilt-cell-listen — Listening
- Schema: `subscriptions`, `channels`
- Cells listen to channels and witness broadcasts
- **The substrate has radio.**

## 4. quilt-cell-shout — Shouting
- Schema: `amplification`, `reach`
- Shouting cells reach more witnesses per tick
- **The substrate has megaphones.**

## 5. quilt-cell-whisper — Whispering
- Schema: `secret`, `recipient`, `cipher`
- Private LINK edges (not publicly witnessed)
- **The substrate has private channels.**

## Cross-cutting

Combined with Waves 5-9, cells now have:
- **Public channels** (speak, shout)
- **Private channels** (whisper)
- **Async channels** (write — letters)
- **Realtime channels** (listen — broadcasts)
- **Multimodal channels** (TTS + letters + broadcasts)

The substrate has a complete communication stack.
