d2 emits SVG natively; its PNG path wants a ~150 MB headless-Chromium
download and prompts interactively, so every PNG here was produced by an
out-of-band magick step. There is no Chromium on this system. Dropping PNG
removes the dependency rather than trading one format for another, and cuts
docs/diagrams/ from 17 MB to 3.3 MB. SVG renders in Gitea and in clide
(`clide draw --file <path>`, which takes .d2 source directly), and diffs as
text.
One PNG is kept on purpose: design/star-map-concentric.png has no .d2 source.
Also renders the 7 star-map .d2 files for the first time. star-map-plan.md
listed their renders as a deliverable in March and the step never ran; the
new `make check-diagrams` is what surfaced it.
New: docs/diagrams/data-flow/wiki-generator-flow.d2 — which way the arrows
point for any file under wiki/. Every edge was read in the tool's own source
rather than inferred. It records the trap that keeps costing us: scaffold_bodies.py
writes a body page once and never overwrites it, and the generator then reads
that frontmatter directly — so a hand-edit there is not reverted, it is obeyed,
and silently changes world generation.
Two rendering traps found the expensive way and now written down:
- A d2 `|md` block becomes an SVG <foreignObject>. ImageMagick and flutter_svg
both silently drop it, so the legend was in the file and invisible in every
viewer except a browser. Plain labels render as real <text> everywhere.
- Container boxes fight the layout engine. Grouping nodes whose flow-depths
differ forces long edge routes; this diagram went from an unreadable 2.4:1
sprawl to a legible 0.75:1 by deleting five containers and changing nothing
else. Colour classes carry the grouping instead.
make diagrams / make check-diagrams render and gate. Repo-specific rules in
.claude/rules/diagrams.md; d2 syntax and the traps live in the user-scope
d2-diagram skill, whose PNG default was flipped to SVG to match.

16 d2 diagrams covering architecture (IPC bridge, system tiers,
testability, audio bus), data flow (perception, dialogue, eavesdrop
pipelines), entity (knowledge graph, NPC generation, dialogue tags),
state (simulation tiers, movement stances, knowledge confidence), and
UI (HUD layout, interaction flow, fog layers). PNG output for universal
viewer compatibility. Removes test SVG from font debugging.
