Categorical Mapping

Core Components

1. VoiceChannelUWD.jl

Core undirected wiring diagram model:

using VoiceChannelUWD

# Create channel with 3 participants (GF(3) balanced)
channel = create_voice_uwd("room-1", ["alice", "bob", "charlie"])

# Compose audio via oapply (colimit)
mixed_audio = oapply_voice(channel)

# Arena play/coplay
play_result = voice_play(channel, "alice")
coplay_result = voice_coplay(channel, "alice", mixed_audio, feedback)

2. VoiceChannelNATS.jl

NATS message broker integration:

using VoiceChannelNATS

# Connect to NATS
client = NATSVoiceClient(channel, "alice")
connect!(client)

# Publish audio (play)
publish_audio(client, audio_frame)

# Subscribe to mixed audio (coplay)
subscribe_coplay!(client) do msg, feedback
    # Deliver to speakers
end

NATS Topics:

plurigrid.voice.{channel}.play.{participant}     # Outbound audio
plurigrid.voice.{channel}.coplay.{participant}   # Inbound mixed
plurigrid.voice.{channel}.peers                  # Peer discovery
plurigrid.voice.{channel}.meta                   # Channel metadata

3. VoiceChannelWhiteHole.jl

macOS virtual audio driver binding:

using VoiceChannelWhiteHole

# Create WhiteHole binding
binding = create_whitehole_binding(channel, "alice")

# Start audio I/O
start_input!(binding)   # Microphone → Channel
start_output!(binding)  # Channel → Speakers

# Color-tagged stream mixing
result = mix_colored_streams(streams)

Stream Colors:

• Hue 0-120°: PLUS (+1) speaking streams
• Hue 120-240°: ERGODIC (0) transport streams
• Hue 240-360°: MINUS (-1) monitoring streams

GF(3) Trit Assignment

Conservation Law:

∀ channel: Σ participant.trit ≡ 0 (mod 3)

Arena Protocol

From Capucci et al. "Parametrised Lenses":

Arena A_G : Lens_{(Ω,℧)}(X,S)(Y,R)

where:
  Ω = Π_{p∈P} {speaking, listening, muted}  (strategy profiles)
  ℧ = Π_{p∈P} ℝ                              (latency/quality)
  X = audio buffer states
  S = listening buffer costates
  Y = mixed audio output
  R = quality feedback

Play:   play_A : Ω × X → Y      (participant → channel)
Coplay: coplay_A : Ω × X × R → ℧ × S  (channel → participant)

Commands

# Run voice session demo
julia plurigrid/VoiceChannelUWD.jl

# Run NATS-integrated session
julia plurigrid/VoiceChannelNATS.jl

# Run WhiteHole audio session
julia plurigrid/VoiceChannelWhiteHole.jl

# Create voice channel
just voice-channel create room-1 alice bob charlie

# Join voice channel
just voice-channel join room-1 --as alice

# Check GF(3) balance
just voice-channel gf3-check room-1

Integration with Existing Skills

unwiring-arena

# Voice channel uses same Play/Coplay protocol
using UnwiringArena

arena = VoiceArena(channel)
arena_step!(arena)  # Full play/coplay cycle

oapply-colimit

# Audio mixing IS oapply
using AlgebraicDynamics

# Each participant is a ResourceSharer
participants = [ResourceSharer([:audio], produce_fn) for p in channel]

# Mix via colimit
mixed = oapply(voice_uwd, participants)

gay-mcp

# Deterministic color assignment
using Gay

color = gay_color(participant.seed)
trit = color_to_trit(color)

Mathematical Foundation

Undirected Wiring Diagram

UWD = (B, J, π: P → J, ρ: P → B, O, o: O → J)

where:
  B = set of boxes (participants)
  J = set of junctions (mix points)
  P = set of ports (audio in/out)
  O = outer ports (external I/O)

oapply as Colimit

function oapply(d::UndirectedWiringDiagram, xs::Vector{ResourceSharer})
    # 1. Coproduct of state spaces (all audio buffers)
    S = coproduct((FinSet ∘ nstates).(xs))
    
    # 2. Pushout identifies shared at junctions (audio mixing)
    S′ = pushout(portmap, junctions)
    
    # 3. Induced dynamics sum at junctions
    return ResourceSharer(induced_interface, sum_dynamics)
end

GF(3) Conservation

For any voice channel with n participants:
  
  1. Assign trits: trit(pᵢ) ∈ {-1, 0, +1}
  2. Conservation: Σᵢ trit(pᵢ) ≡ 0 (mod 3)
  3. If n = 3k: assign k each of {-1, 0, +1}
  4. If n ≠ 3k: some participants must share trit

GF(3) Triads

voice-channel-uwd (0) ⊗ gay-mcp (+1) ⊗ temporal-coalgebra (-1) = 0 ✓
voice-channel-uwd (0) ⊗ oapply-colimit (+1) ⊗ sheaf-cohomology (-1) = 0 ✓
unwiring-arena (0) ⊗ voice-channel-uwd (0) ⊗ bisimulation-game (0) = 0 ✓

GF(3) Naturality

The skill participates in triads satisfying:
