CB-WP-0037 T02: the engine's rules against the edition's

Vendored DARVO.csv, Relations.csv and Scenarios.csv — the three unread
files that carry mechanism. The engine has implemented the DARVO sequence
and relation formation/breaking from GroundRules.md since the beginning,
and had never read the game owner's statement of them.

Every checkable clause agrees, and agreement is recorded rather than
noted: a survey that finds nothing and leaves no trace cannot be told from
one never run. The two hardest clauses to notice were already right —
Focus placed "even if the Attack was cancelled", and Focus removed when
the sequence ends before REVERSE.

The tests are tripwires, not derivations. The match was made by a person
reading prose, and that reading goes stale in silence when the prose
changes; each behaviour pins the phrase it was read from, so a reworded
edition goes red and asks for a human. Mutation-proven by rewording the
cancelled-Attack clause.

F25 raised, and it is the real yield: Scenarios.csv carries
threshold_2_players/3_4/5_6, starting_stress and round_track, and the
engine hardcodes all three — a match returning 5/7/9, stress: 2 at setup,
five rounds. They agree on all four scenarios. These are the most
contested numbers in the project; the whole 4/6/9 vs 5/7/9 episode turned
on them, and the engine has been right by maintenance coincidence rather
than by reading the file that owns them.

Also pinned: Problems.csv and Scenarios.csv both state the deal and the
engine reads only the first. They agree; nothing was checking.
