Patrick Plate 1d8849cb41 fix(mcp-image-gen): confirmed working FLUX.2 Klein encoder filename
- CLIPLoader clip_name: qwen_3_4b_klein.safetensors (from Comfy-Org/vae-text-encorder-for-flux-klein-4b)
- VAE: flux2-vae.safetensors (321MB, same repo)
- Live test confirmed: 2.1MB photorealistic 1024x1024 PNG in 52.43s on RX 7900 XTX
- Test: assert clip_name == qwen_3_4b_klein.safetensors
- 37/37 tests pass

Patrick Plate 4a99a3625a fix(mcp-image-gen): rewrite flux2_klein_heretic workflow with CFGGuider + correct node types
- Replace FluxDisableGuidance+BasicGuider chain with CFGGuider (cfg=5)
- CLIPLoader: add device='default', keep type='flux2'
- UNETLoader: weight_dtype='default' (not fp8_e4m3fn — avoids dimension mismatch)
- VAEDecode/SaveImage: updated node IDs (11→VAEDecode, 12→SaveImage)
- Encoder: qwen_3_4b_bfl.safetensors (7.5GB BFL-merged shards)
- Tests: update heretic model assertions for new node structure (37/37 pass)
- Add RECAP doc with root cause analysis and session history

Patrick Plate ea0c5d39c4 fix(mcp-image-gen): fix Heretic/FLUX2 integration bugs
- Fix syntax error in server.py (dangling docstring lines)
- Correct model filename: flux-2-klein-4b.safetensors (without -fp8)
- Fix _WORKFLOW_REGISTRY key to match actual downloaded filename
- Update get_models() to always include registry models as fallback
- Fix test expectations to match corrected model names
- All 37 tests passing

Patrick Plate 79f1e6d65f feat(mcp-image-gen): add name and count params to generate_image
- Add name (str) param: filename prefix saved as {name}_{timestamp}_{seed}.png
- Add count (int, 1-10) param: generate N images in one call
- Extract _sanitize_name() helper: strips special chars, collapses underscores, caps at 64 chars
- Extract _build_filename() helper: pure function for testable filename construction
- Extract _generate_single() coroutine: clean loop body for batch generation
- Fixed seed batches increment seed per image (seed+i-1) for deterministic variation
- random seed (-1) batches give independent random seeds per image
- Partial batch failures continue (error TextContent in slot, remaining images proceed)
- Returns flat interleaved [Text1, Image1, Text2, Image2, ...] list
- 34/34 tests passing (was 19, added 15 new tests)

Patrick Plate 8112ff2f12 feat(mcp-image-gen): scaffold ComfyUI-backed image generation MCP server
- FastMCP server with 4 tools: generate_image, list_available_models,
  get_generation_status, get_output_directory
- ComfyUI REST API client (httpx) polling lifecycle
- FLUX.1-schnell workflow JSON template
- Dual output: TextContent (path + seed) + ImageContent (base64 PNG)
- 14 passing pytest tests with respx HTTP mocking
- ROCm/AMD RX 7900 XTX optimized setup in README
- Ollama Linux migration path documented (future)
