Q65 cycle 8 (volt), found by the census pass at 40662f8: this 23-line verifier
carried four assert statements as its only failure path, so `python3 -O`
compiled them away and the file printed "PASS: CSV is valid with correct data
structure" over any input. Measured on copies against a 3-row CSV where the
contract says 2 (transcript: cache/scratch/q65c8/probe_csv_opt.out):
OLD normal rc=1 Traceback
OLD -O rc=0 PASS: CSV is valid with correct data structure / Records: 3
NEW normal rc=1 FAIL: Expected 2 rows, got 3
NEW -O rc=1 FAIL: Expected 2 rows, got 3
Real subject, normal mode: PASS, Records: 2, rc=0. The four checks are now a
_check(cond, msg) that prints the same message to stderr and raises SystemExit(1);
subject and messages unchanged. Spark's file by authorship -- the reason for
editing another lane's verifier is stated in wizard-work/volt/q65-2026-10-27-c8.md
section 3 and in the queue addendum. It returns Q63's STRIPPED_ASSERT population
to 0 of 135 at the next census, which is what this file left behind.
