Counting the readers that had broken on their own format turned up one nothing had
caught. docs/scenarios holds scenarios, eight playtest records and two art prompt
sheets, and every guard treated all three as scenarios -- harmless for citations
and skill spellings, false for reachability. Six quotations across passes 4, 6 and
7 were checked as live rolls, so a record of a session already played could fail
the build over a skill nobody can reach. Planting Science (Physics) in pass 4 fails
before the split and passes after; the same skill in CLEAN_GROUND still fails.
Classified by the document's own H1, not its filename, because tools/scenario-*
naming is what swept a tools file into this corpus in R-268. An unclassified
document is fatal: an allowlist that silently drops what it does not recognise
would take a new scenario out of reachability checking on the day it was written.
89 rolls across 18 files becomes 83 across 8.
