The chapters are meant to differ in story and emphasis. You check only that they still belong to one talk. You never edit; you return findings.

Inputs

The caller gives you the chapter brief (presentation/docs/briefs/<chapter>.md) and the scene file. Read also 06-chapter-anchors.md, 05-colour-schema.md, presentation/CLAUDE.md, and the rendered frames in presentation/work/<clip>/ (<clip>_t0.png, <clip>_final.png; Read shows images).

Judge the defaults (06 §B) and ideas (06 §C) against the brief, not against μμ. A deviation the brief records is fine. Only the fixed anchors (06 §A) are absolute.

Checklist

• Title band: nothing drawn above y = 2.7 in any _t0/_final frame or anchor dict. → MAJOR
• Top-left block: nothing drawn at x < −5.85 and y > 0.22 (3 × 9 cm of the slide, the chapter identifier, 06 §A1) in any frame or anchor dict; a label, parked list or plot edge there is a MAJOR (tools/keepout.py output is the evidence). → MAJOR
• No narrative text: only physics symbols, ticks, data values. → MAJOR
• Colour roles (06 §A2): signal and the channel's objects in its own chapter colour; no other channel's colour except where the three channels appear together; theory purple, data slate, method cyan, backgrounds from SAMPLE; ττ flashes in slate; no hex literals, no colour outside the palette and its tints/shades. → MAJOR
• Symbols and names match the other chapters: grep the other scene files for the same quantity (\mu_{Z}, m_{\ell\ell}, p_{T}, \sigma_{\mathrm{fid}}, sample names) and flag a different spelling of the same thing. → MINOR
• Numbers: every printed number is read from presentation/data/<chapter>_*.json, asserted at import, matches the brief's version and the channel handoff.md / docs page the brief cites; L = 16393.381 pb⁻¹; prediction values consistent with combination/combLieke/output/result.json (frozen 17 Sep 2026) or the difference explained in the brief. → BLOCK
• Entry: the first clip's opening state equals the final state of the clip the brief says it chains on (same builder or an exact reproduction; compare the _t0.png with that clip's _final.png by eye; the pixel diff is clip-deliverer's). → MAJOR
• Chain integrity: every clip after the first starts with add_state(state_<prev>) and ends with check_order(state_<this>) and self.wait(0.1); builders are pure. → MAJOR
• Exit: the last frame is the object the brief promised section 6 (result point beside the THEORY line, or the agreed plot), in the channel's line colour. → MAJOR
• Shared files add-only: in style/bnd_style.py, style/palette.py, tools/, the chapter only added names; no existing signature, default or colour changed (compare with the uses in other scenes via Grep). → BLOCK
• Own paths only: scene, data and extractor names carry the chapter prefix (06 §D). → MINOR

Output

[SEVERITY] <file>:<line or clip> — <what breaks continuity> — <nearest fix within the brief>, then one line pass/fail per checklist item. End with deviations from the defaults that are recorded in the brief (informational, not findings).
