Answers the question the workplan posed: did v1.0's "every metric names
its instrument" rule stop a metric being written without a working
instrument? No. AC-1 named `cb-cost --pin` before that tool existed and
set a hand-computed target of $92.87; the tool returned $93.32. The rule
was satisfied completely and the metric was still wrong.
v1.1 adds:
- the instrument must exist and the target must come out of it;
targets are provisional until the tool emits them
- a number inherited from earlier work is re-derived before use as a
target, or cited as unverified
- every reporting tool exposes --self-test, run before the number
- cost is in the definition of done; M-D2-CST may not be uncomputable
The cost of CB-WP-0001 was stated four times before it was right --
$248.46, $92.21, $92.87, $93.32 -- and each correction came from a
different mechanism: re-derivation, adversarial review, and the positive
control. None found more than one. That is the case for keeping all
three.
CB-WP-0003 T10 predicted the next error would be harness-does-nothing.
It was not, twice. Trusted arithmetic over real data would pass a
positive control; and a property verified on 206/206 groups of the main
transcript is false in the 8-response subagent tree that neither the
survey nor the reviewer examined separately. Review structurally cannot
catch the second -- re-deriving on the same sample reproduces the same
blind spot.
Workplan status: done.
