mAi	127bbf3ed5	mAi: #2 - phase 2 ComfyUI Go adapter, tests, config sample ... internal/backend/comfyui.go implements the Backend interface against ComfyUI's /prompt + /history + /view HTTP API. Workflow is the canonical FLUX.1 schnell shape — UNETLoader + DualCLIPLoader (clip_l + t5xxl fp8) + VAELoader + ModelSamplingFlux + KSampler — assembled as a Go map per request so Width / Height / Seed / Steps / sampler / scheduler all flow into the right node inputs. Resilience: one retry on /prompt 5xx and transient network errors, no retry on 4xx. Connection-refused / timeouts surface a 'boot-whitetower mrock' hint. node_errors mentioning a missing unet point users at docs/setup-comfyui-mrock.md (matches both the 4xx and 200-with-errors shapes ComfyUI uses across versions). Result.Metadata carries model, seed_used, latency_ms, steps, sampler, scheduler, width, height, prompt_id, client_id, plus best-effort vram_used_mib pulled from /system_stats post-gen. Tests use httptest with poll interval squashed to 1ms — no real mRock dependency. Coverage: happy path, defaults, retry-once on 5xx, give-up after two 5xx, no-retry on 4xx, missing-model hint (both 4xx and 200+node_errors paths), history-error surfaced, /view 4xx, unreachable host, ctx cancel during poll, workflow-shape assertion, registration. Config sample: flux-schnell-local is now default_backend; the user-facing block names the unet file by basename (the mapping into models/unet/ is the server's convention, captured in docs/setup-comfyui-mrock.md from phase 1). Smoke verified end-to-end: imagen generate ... --backend flux-schnell-local --size 1024x1024 --output /tmp/cat-via-cli.png on mRock returned a 1024x1024 PNG of a cat in a fishbowl in 10.3s with a sidecar carrying seed + latency_ms + the rest of the metadata.	2026-05-08 16:59:21 +02:00
mAi	237270b204	mAi: #211 - bootstrap ImaGen framework skeleton ... First step of the model-agnostic image-generation framework. Lands the plumbing other components (skill, ComfyUI/Replicate adapters, agents) will plug into: - internal/backend: Backend interface (Request/Result), thread-safe Registry with init-time Register, plus a Mock reference adapter that emits a deterministic gradient PNG for smoke tests. - internal/config: YAML loader for ~/.config/imagen.yaml. Framework owns default_backend + output settings + a per-backend block; each adapter owns the schema below its own block via BackendSpec.Raw. - internal/output: filename templating ({date}/{time}/{slug}/{seed}/ {backend}/{ext}), JSON metadata sidecar, --output override path. - internal/prompt: embedded styles.yaml, style-preset suffix application. - internal/server: 501 stub — HTTP surface lands in a follow-up issue. - cmd/imagen: generate / backends / config (init|validate|path) / serve / version subcommands. Stdlib-only flag parsing with a small helper to honour positional prompt args ahead of flags (matches the issue spec). - Tests for output (slug, naming template, sidecar), backend (mock PNG validity + determinism, registry build + duplicate panic), config (round-trip + validation), prompt (style apply + unknown-style error). - CLAUDE.md, README.md, docs/architecture.md, docs/usage.md, Makefile. Acceptance criteria from #211: 1. go build ./... — clean 2. imagen backends — lists registered backends, exits 0 3. imagen generate "test prompt" --backend mock --output /tmp/x.png — writes a 1024x1024 PNG plus an x.png.json sidecar 4. imagen config init | imagen config validate — round-trips cleanly 5.
