OBS Spout Streaming

Current Status

The Python/OpenGL Spout sender has been deleted.

LocalCastBridge no longer carries a runnable OpenGL publication path. The only surviving pieces are diagnostic packet/brush math in localcast.diagnostics.render_math and typed diagnostic visual documents in localcast.diagnostics.visual_cache.

Production Spout2 publication belongs to Aquarium.

Target

native rolling reservoir
-> Aquarium typed runtime state
-> GPU feature/fusion/material/brush buffers
-> D3D render target
-> Spout2 sender texture
-> OBS Spout2 Capture

Invariants

• OBS receives a named Spout2 texture from Aquarium, not Python/OpenGL.
• LocalCastBridge may expose diagnostic typed documents and CPU render math, but it does not own the production renderer.
• JSON remains a diagnostic/status surface only.
• The neighbor SRT video feed is a timed media artifact and must share the same presentation ledger as Aquarium output and Faust audio.
