Documentation

README

Excerpt

Build Product Demo

Turn verified product behavior into a compact proof story. Treat the final media as an executable claim about the product, not as a decorated feature list.

Choose the mode

Plan: inspect the product and produce the brief, evidence inventory, feature coverage, director treatment, script, and beat plan.
Produce: complete the plan, create deterministic setup and capture tooling, record, edit, and verify the final media.
Diagnose: inspect an existing demo, identify the first broken layer, and revise the smallest responsible artifact. Check truth, story, visible state change, attention, narration/action alignment, capture, then encoding.

This is the opening of the README. Read the full README on GitHub.
