Truth binds claims not demonstrations; conversion lives inside the form

Paul's probe review (recovery-ab): the no-invention rule was blocking
bold greenfield directions whose demonstration data does not exist yet;
kids-reading amplified the product's "quiet support" adjectives into a
whole-page aesthetic; and nothing guaranteed a Persuade surface still
sells once the form commits (a prior generation shipped zero nav and
zero CTA in the first viewport).

- Truth split in two: commercial and factual claims stay uninventable;
  illustrative material is authored at full fidelity, labeled synthetic,
  with a replace-with-real list for the user. Mirrored in the build
  section so execution-only sessions get it too.
- Persuade floor restored from a22: conversion lives inside the form's
  own vocabulary (one-line hook, visible primary action, legible reading
  order); a committed form that hides the offer has not finished
  translating. The contract's FIRST VIEWPORT block now names where the
  primary action sits, and the finishing review verifies the mode did
  its job.
- Calibration: negative constraints rule out devices, not exuberance;
  product-behavior adjectives do not dictate surface energy.
- Web leverage: when the chosen world names a technique (canvas, WebGL,
  view transitions), build the technique, not a static imitation.

-Before code, state the chosen direction as a contract in the artifact's opening comment, five short blocks, 150 words at most. THESIS: the one idea this surface owns and the category-default arrangement it refuses. OWN-WORLD: the palette and component language, specific enough to be recognizable with all content removed. STORY: what the visitor understands, believes, and does. FIRST VIEWPORT: the exact composition, what is where and at what scale. FORM: the chosen form, its position on your ordered list, and the seed key the script printed. If a block reads like a mood, the direction is not decided yet; the finishing review audits the render against this contract. <!-- rule:skill-decide-then-build -->

 - **Author motion as material.** The form has native motion, what it does in life between states; give the page that motion once, orchestrated, rather than scattered hover effects. Bound expensive effects and keep content visible by default.

 When the harness can run a separate agent, this review belongs there, not in the build thread: give it the original request, confirmed answers, the artifact path, its direction contract, DESIGN.md, and existing hook findings. Ask for a short list of material fixes, promise by promise against the contract, apply them, and finish. Do not run a second detector. <!-- rule:skill-finish-separate-reviewer -->
