# Delivery checklist

A clean build only proves TeX and package invariants. Inspect the figure before delivery.

## Semantics

- [ ] Every node is one object with one role.
- [ ] Every edge is data flow, control flow, dependency, or causality.
- [ ] Every group names a real composite, binds at least two members, and all members belong to it.
- [ ] At most one `\sfcallout`, hanging off a finished band, not off a single node.
- [ ] Captions explain objects or relationships, not decoration.

## Layout

- [ ] No node covers another node, caption, edge label, or group border.
- [ ] Flow rows start on the same left rail.
- [ ] Edge labels sit on their own edge and do not cover unrelated objects.
- [ ] Fixed coordinates are on a coarse grid, not tuned against one label width.
- [ ] Captions in a row share one baseline.
- [ ] Meaning box is one column, at most three rows, no overflow.

## Style

- [ ] One role keeps one hue across the whole figure.
- [ ] At most four active hue families plus gray.
- [ ] Three visibly separated lightness levels where objects need hierarchy; no uniform pastel.
- [ ] Borders are neutral; group outlines carry their members' role hue.
- [ ] No saturated primaries, shadows, banners, or decorative cards.

## Thumbnail

- [ ] Open `*-thumb.png` (360 px). The main claim is still legible.
- [ ] Hues remain distinct and muted; text has not collapsed into gray mush.

## Delivery

- [ ] PNG preview shown.
- [ ] One-paragraph mechanism explanation in prose.
- [ ] `.tex` source and PDF/SVG linked.
- [ ] Any degraded path or inferred relationship stated explicitly.
