Annotated Wash Diagram

Provide the verified mechanism/subject, required callouts and vocabulary, audience, intended use and desired aspect ratio. Resolve missing factual and rights information first. Convert the material into a component-and-relationship table that can be checked before any drawing is commissioned.

Choose one viewpoint, hierarchy and spacing for the mechanism. Reserve uncluttered annotation lanes and state the pale wash, fine graphite line and paper texture treatment. Write a new English brief from approved facts; exclude copied prompts, branded product designs, dense small text and invented technical claims.

Have Node.js 20 or newer and a FAL account with FAL_KEY available in the environment. Use the bundled generator with the approved prompt file, output directory and filename prefix. It submits one paid task for exactly three 1536×864 variants at high quality and requests PNG. New generations incur separate provider charges.

Keep provider-task.json in the output directory. Once an ID has been saved, the same prompt/directory resumes that request; a saved failed task is blocked from automatic resubmission. The script saves its task record only after a successful submission response. If that response or record write is lost, check provider history before retrying: the wrapper does not provide an atomic pre-submit intent or an exactly-once guarantee. Downloaded variant paths can be overwritten on a later resume, so preserve reviewed copies separately.

Inspect all three images for distinct compositions, exact dimensions/ratio, legible hierarchy and correct components, connections and ordering. Reject repeated panels, watermarks, source identities, broken anatomy where relevant and unsupported visual relationships. A provider response with three URLs satisfies the script’s count check, not these visual/factual checks.

Add approved labels and citations after generation in a deterministic layout tool. Use restrained inline Lucide-style SVG for legend/callout cues; do not use emoji, dingbats or icon fonts. Recheck every visible relationship and any displayed value against the approved table, mark unknowns for verification, and deliver the annotated concept image with its evidence limits clear.
