What

Optional aiBridge.demo (agent window) in scripts/schemas/challenge.schema.js, per spec #91, section "aiBridge.demo".

• Frame: channel ≤ 28, agent ≤ 24, time 24-hour HH:MM, opening {kind: question | statement, text ≤ 70}, footer ≤ 60, optional note ≤ 90.
• elements: 1 to 4, discriminated on type:
  • kpis: items, exactly 3 of {value ≤ 10, label ≤ 16}
  • figure: {value ≤ 12, caption ≤ 48}
  • progress: percent and optional target, integers 0 to 100
  • status: {label ≤ 24, value ≤ 32, state: ok | alert}
  • buttons: labels, 1 to 2, each ≤ 20
• Every object is strict, like the rest of the schema.
• An unquoted time such as 14:32 is read by YAML as the base 60 number 872. The error then says to quote the time.

Fixtures

The five mockup windows (ocobo-revops/prototype, enjeux-*.html) are in their golden fixtures, text verbatim. Revenue AI keeps none and still passes. Each window has four elements, and a test asserts it.

Tests (seam 1)

scripts/__tests__/challenge.schema.test.js covers:

• each element type, an unknown type, a missing type and a fifth element
• each cap at its limit and one past it
• malformed times (not trimmed, see the schema comment) and the unquoted YAML time
• both opening.kind values
• progress bounds, status states and button counts
• unknown keys inside the demo
• missing fields and unknown keys in the frame, the opening and every element type
• the file without a demo

Review notes

• Bold lead lost, accepted. The Customer Experience mockup opens with a bold lead: "Risque de départ détecté. Score de santé : 72 → 54." The schema stores the opening as plain text, so the bold is lost. This loss is accepted. An optional opening.lead field is out of scope here.
• note stays optional (assumption A3, fictional accounts). No mockup carries one yet.
• French/English consistency is deferred. Matching time and element type sequence between languages belongs to French and English consistency of challenge files #99.
• Expected conflict with the partner PR (Partner block in the challenge schema #97). It edits the same schema, test tables and fixtures. Both sides only add rows, so the rebase conflict is mechanical.

Closes #96
