tegwick b1f4a85a4a CB-WP-0021 T04: evidence -- the endings are tight, and the cost chain snapped
Closes CB-WP-0021, four days after its code landed.

The budget was the wrong one and ADR-0011 corrected it: csv costs 17,651
against AM-4b's 19,742, so it FITS, and was refused on proportion anyway
(89% of the remainder to read 20 rows). Third premise this pass corrected,
second against a mis-chosen denominator. That pattern now has three
instances and no control -- facts-check catches copies that disagree,
nothing catches a number computed correctly against the wrong base.

The hash blast radius was PREDICTED, not discovered. T01's brief required
it be established before writing code and ADR-0011 D3 measured it: 0
scenario files pin a state hash. Verified today, replay-test 14/14 and
AM-7 at 0.985/0.998/1.018 against a 0.9 floor. What actually broke was six
scenarios' data, not any logic.

The endings mean something and they are tight. Played 2p all-bots: total 4
/ threshold 5, group failure, 6 available. T02's control predicted a full
clear is required at 2p and play confirms it -- leaving any single Problem
unclaimed loses at two seats.

T04's last bullet cannot be satisfied. cb-cost.py --slug CB-WP-0020 ABORTS
-- no transcripts retained -- and the instrument refusing to estimate is
correct behaviour, so the number is absent rather than wrong. 41.6% of
spend is UNATTRIBUTED. The quote-the-previous-pass rule breaks after about
four passes and needs a bound; this is the first pass where the chain
actually snapped.

loop-lint's own-cost rule caught the first draft quoting this pass's own
cost as final. Marked provisional -- the rule working.
