Svrnty 2a90c3f884 feat: initial scaffold — FastAPI shell + stub vision routers
Phase 4a of the BTE refactor (audit 2026-05-24 §3 V). svrnty-vision is a
sovereign HTTP gateway in front of four vision capabilities — VLM (Spark 2
Qwen3-VL), FLUX image gen (Spark 1 ComfyUI), palette extraction, and
background removal. This commit lays only the scaffold: FastAPI app,
/healthz, four 501-stub routers, pydantic-settings config, pytest smoke.

Real implementations land in Phase 4b. BTE code is untouched in 4a.

svrnty-vision

Sovereign vision HTTP gateway. FastAPI shell that exposes four endpoints:

Endpoint Purpose Implementation
POST /vlm/analyze Vision-language model evaluation Proxies to Spark 2 (Qwen3-VL via vLLM)
POST /flux/render Image generation Proxies to Spark 1 (FLUX on ComfyUI)
POST /palette/extract Dominant-color palette In-process (Pillow + colorthief)
POST /rembg/cutout Background removal In-process (rembg)

Plus GET /healthz for liveness.

Why it exists

Brand Truth Engine (BTE) is a .NET 10 + Svrnty.CQRS service. Vision tooling (VLM, image gen, palette, rembg) was originally embedded in BTE with cloud provider SDKs (Anthropic, OpenAI, Google, Higgsfield). Per the 2026-05-24 refactor audit, that surface is extracted into this sibling repo so BTE stays narrow and sovereign-first.

Architecture invariant

svrnty-vision is a thin HTTP gateway — it does NOT run heavy ML models in-process. Qwen3-VL runs on Spark 2 (vLLM). FLUX runs on Spark 1 (ComfyUI). svrnty-vision orchestrates HTTP calls to those services and normalises the responses for BTE.

The two in-process exceptions (palette, rembg) are CPU-light Python libraries — Pillow/colorthief and rembg respectively. They land in 4b.

Status

Phase 4a (this commit): scaffold only. All four endpoints return HTTP 501 Not Implemented. /healthz returns 200.

Phase 4b will port the real logic. Phase 4c deletes the corresponding .NET code from BTE. Phase 4d wires BTE to call svrnty-vision over HTTP. See /home/svrnty/workspaces/hermes/sot/01-ROADMAP/BTE-REFACTOR-EXECUTION-PLAN.md.
