[x3d-public] On SAI Issues for MCCF

[cbullard at hiwaay.net]

This sounds promising. John.

We need some resolution on X_Lite SAI questions.  A polymorphic SAI is 
good for advanced renderers that accomodate multiple formats but are 
challenging to developers relying on the W3DC documented SAI. I'm unsure 
how that is bridged.  We consumed a lot of resources throwing things 
against the wall to see what sticks and punted to transparency. That 
worked but we were hoping to use colors that map to our dashboard and 
other displays in the app. One issue is where developers are using 
foundation models, undocumented APIs will not be training data because 
they are not scraped.  That will be a problem for new developers trying 
to apply X3D engines to visualization work.

  MCP was discussed and will be a work item in a future version.  For 
development the Ollama desktop app is sufficient.  The field concepts 
are working and can be demoed.


As for MCCF today:

What is working as of V2.1.13:

Constitutional arc with varying E/B/P/S channels
Transparency from coherence — avatar fades through arc
Genre classification — Drama 97% — visible in UI and export header
Arc auto-save to exports\ directory
X3D scene lit correctly, HotHouse connected

First items for the new session:

Verify the export header fix landed on your machine
Avatar translation from S-channel (next visual feature)
MCP as V2.3 interface layer — add to backlog
