Assertions that read the right field

Assertion studio: L4.1 priced the rungs and left three hand-written checks in place, so this lesson writes four assertions and finds the reach is set by the token, not the threshold. "The first number in the text is the amount" accuses 15 of 16 passes because on 28 of 50 rows the first number is a day, a code, a latency or a card run; a money token accuses none. A schema pinned to the v3 shape flags all 20 v2 rows — 10 failures, 10 passes — and scoped by version flags none. The execute invariant fires on 24 rows unscoped and 4 scoped, all real. Canonicalising the clause mark keeps all 29 catches and drops 4 false alarms to 0, and respelling a clause mark flips 30 of 42 literal verdicts against 0 of 42 canonical. The suite lands at 29 of 34 with no false alarm, missing only retrieval_dropped_clause.
