An experiment, at Jeroen's request: predict how the wiki seed data is structured
WITHOUT reading it, seal the prediction, then score it. The prediction is
a1addf7e2, committed before wiki/ was opened so it could not be retrofitted.
The score, against a rule fixed in advance:
RIGHT — markdown + YAML frontmatter, TOML for economics tables, the body path
shape, more trees than the three I had seen.
WRONG — "a source, never an output". That holds for 253 pages and is backwards
for 3,262: star-systems/ is GENERATED from systems.db by tooling/db/wiki_sync.py,
its <!-- READ-ONLY --> blocks are renders, and body frontmatter IS the body
definition rather than a description of one. Also wrong: "probably no schema
docs" — there are 17 templates, ten authoring guides, economics/schema.md and a
GOVERNANCE.md that states the ownership models plainly.
ABSENT (the expensive bucket) — the two ownership models running in OPPOSITE
directions; the GTTR prose channel; terrain.npz/globe.png; that stations and
districts have NO wiki directories; that `description` frontmatter exists so
agents can filter before loading; and the scale, 11,864 files.
ROOT CAUSE, and it is not missing documentation. The wiki documents itself well.
It was unreachable: wiki/ appears in NEITHER CLAUDE.md's Project Structure block
NOR .claude/rules/project-structure.md, the annotated tree whose entire job is
orienting an agent. The largest tree in the repo — the seed for the whole Reach —
was invisible from both files a session reads first. Every item in the absent
bucket follows from that one omission. The proof is this session: it spent three
days fixing Ferrath's terrain rendering and never once saw
wiki/star-systems/GJ-820B/bodies/GJ820Bc/index.md, the file that defines Ferrath.
Fixed here: wiki/ enters both structure documents with the ownership split stated
where it will be read, and Skill(wiki) carries the traps — never hand-edit a
READ-ONLY block or body frontmatter, stations have no directories, the id is
spelled two ways, editing corp PROSE stales systems.db, and absent variance is
often deliberate rather than a gap.
That last point cost two false findings in one measurement and is worth the
warning: chemosynthetic:false on every body is a namespace reservation for
dextro-DNA-style biochemistry once geology and nature spawn to the 1x1m pixel,
and enabled:false on ~65% is staged rollout — clean planet types first, generator
scripts for the rest after. Both read as defects without the roadmap.
Also measured, since the seed's job is to supply variance: continuous axes are
rich (unique seed per body, 460-716 distinct values across orbit/tilt/ice/land)
while the categoricals that gate morphology are concentrated (68% tectonics low,
51% planet_class frozen). Filed as T-1244 with the design question stated first —
whether the distribution is intended — rather than as a defect.
Method caveat recorded in the findings: the aggregator reads scalar frontmatter
only, and atmosphere_color's "100% null" was a parser artefact, not a finding.
