CB-WP-0037 done: T03 classification and T04 evidence

Reading Player_Mats.csv and Glossary.csv — which O4 had forbidden
declaring about until they were read — found a rule. Player_Mats'
choice_rule column IS GR-R03: at Stress 4-5 choose ATTACK or GROUND unless
you spend a ready Freedom token. The engine's stress_gated and
allowed_under_stress_gate match it exactly, and now have a tripwire.

So Ornamentation.md gains §1.3: the unit is a column, not a file.
Classifying Player_Mats as ornamentation would have thrown a rule away
with the colour swatches. A mixed artifact is normal — a player mat is a
rule printed on a decorated card in the box too. O4 is rewritten and
re-grounded from provisional to rule accordingly.

O5, O6, O7 declared with falsifiers. O7's is not theoretical:
back_design_id is unread in four vendored files, and hidden information is
what card backs are for.

CB-EV-0029 answers T04's question per rule rather than as a count — yes,
every checkable clause — and states the reading that result does NOT
support: it shows GroundRules.md was a faithful secondary source for the
clauses with behaviour to check, not that the engine is correct.

10 of 19 files vendored. Nine still unread, and Rules_Text.csv is the one
that matters: every clause checked here was checked against our own
transcription of it.
