🎯 EPIC: TRI-NET Phone Video Mesh — phone camera → mesh radio → phone display

[gHashTag]

Epic: Phone Video Mesh

Goal: Smartphone camera → H.264 → UDP → P203 mesh node → 5.8GHz radio → P203 → UDP → smartphone display.

"Walkie-talkie для видео": one tap — видишь что на другом конце mesh сети, без интернета, без вышек, без SIM.

Architecture

[iPhone Camera] → H.264 encode → UDP:7000 → [P203 Mini: trios_meshd_video]

What's done ✅

Component	File	Status
iOS app (modular, 5 files)	tri-net-phone/TriNetVideo/	✅ Camera + H.264 + UDP + UI
Mesh topology map	MeshMapView.swift	✅ Real-time polling, node circles
Video bridge spec	specs/video_bridge.t27	✅ 21 tests, 3 invariants
Topology spec	specs/mesh_topology.t27	✅ 20 tests, 4 invariants
UDP bridge daemon	src/bin/trios_meshd_video.rs	✅ 280 lines, fragment/reassemble
FPGA LCD (color bars)	lcd_official_port.bit	✅ Working
FPGA framebuffer (64 BRAM)	lcd_cam_bram.bit	✅ BRAM inference works
Camera I2C	reg_config.v	✅ 251 registers written

What's blocked ❌

Blocker	Impact	Fix
AN5642 camera dead (PCLK=0)	No FPGA video source	Use phone camera instead
Apple PLA agreement	Can't test on real iPhone	Accept in developer portal
H.264 decode on phone	Can't display received video	VTDecompressionSession
UDP bridge untested on P203	Mesh relay not verified	Flash + test on hardware

Sub-issues

• #TBD: H.264 decode on iOS (VTDecompressionSession + Metal display)
• #TBD: Test trios_meshd_video on P203 Mini (2 boards)
• #TBD: Real topology query (replace mock with TOPO_REQ/RESP)
• #TBD: Apple PLA agreement + signing
• #TBD: End-to-end demo: PhoneA → P203 → radio → P203 → PhoneB
• #TBD: Android port (Skip.tools or Kotlin Multiplatform)
• #TBD: App Store submission

Milestones

Phase	Gate	ETA
Phase 1: App local	Loopback test on iPhone	1 day
Phase 2: Mesh integration	Phone→P203→P203→Phone video	3 days
Phase 3: Production	App Store + field test	2 weeks
