Select Art Pipeline

When to use

• Starting any visual or art-production request governed by STYLE.md.
• A prompt explicitly requests proof-to-model assets, image generation, direct Bubo LOCAL generation, code-first Three.js models, Blender production, floor-plan buildings or schematic assemblies.
• CSS/SVG interface-only work follows style guidance independently; do not start reconstruction or resolve a retired vector pipeline.
• Explaining which pipeline is active without changing the repository contract.

Workflow

1. Read and validate STYLE.md with ./commands/validate-style-contract.sh.
2. Normalize explicit prompt language to CLOUD, LOCAL, PROOF_TO_MODEL, CODE, BLENDER, FLOOR_PLAN_TO_MODEL or SCHEMATIC_TO_MODEL. A prompt override may select any registered pipeline, including one outside the contract's allowed alternatives.
3. Resolve the prompt override before the primary pipeline with ./commands/resolve-art-pipeline.sh. If no override exists, use the primary pipeline in STYLE.md.
4. For an override, write the resolver evidence below the active .hephaera/.cache/tasks/<task>/ folder. Preserve selectionSource: prompt and the active style-contract hash.
5. Read the resolved pipeline contract under .styles/.pipelines/ and follow it together with the selected art-style template.
6. For CLOUD or LOCAL image generation, also read MEDIA.md. Existing-proof PROOF_TO_MODEL, CODE, ordinary BLENDER and procedural FLOOR_PLAN_TO_MODEL/SCHEMATIC_TO_MODEL do not require MEDIA.md; read it whenever cloud/local generated inputs are in scope. Route these model workflows to build-proof-to-model-assets, build-floor-plan-models or build-schematic-models respectively after resolving skill compatibility; never implicitly invoke a generator.
7. If the selected capability is unavailable or fails, stop and report the failure.
8. Route LOCAL generation to use-bubo-local-generation through the pinned Bubo runtime. Selection alone never authorizes setup, model loading, generation, an additional candidate/revision allowance or runtime promotion. Audio uses MEDIA policy independently of this visual selection workflow.

Output

• Canonical selected pipeline and whether it came from the prompt or STYLE.md.
• Active style-contract path and SHA-256.
• Task-local evidence path when a prompt override is used.
• A clear stop reason when the selected pipeline cannot proceed.

Guardrails

• Do not rewrite STYLE.md for a task-local prompt override.
• Do not silently switch or fall back between pipelines.
• Do not require MEDIA.md for existing-proof PROOF_TO_MODEL, CODE, ordinary BLENDER, or procedural floor-plan/schematic work. Reject retired CSS3/CSS/vector/css-vector pipeline aliases and explain migration.
• Keep selection evidence below .hephaera/.cache/tasks/ and never persist credentials.
