The price sheet had two defects of one shape -- a schema that could not
hold the fact it needed, the same criticism the cost survey levelled at
the State Hub.
CA-16 time-boxed rates are DATA. Sonnet's intro price lived in a
`# intro ...` comment and was invisible to the collector that
reads the file. Now promo_input/promo_output/promo_until,
applied per response at its own timestamp.
CA-17 the 90-day staleness rule was prose in MetricsAndScenarios 1a
that every M-D2-CST verdict silently inherited. Now `recorded`
+ `max_age_days` in the sheet, and a stale sheet ABORTS.
Both are exercised by make cost-test: the promo rate must apply before
2026-08-31 and lapse after, and a 102-day-old sheet must trip.
Applying CA-16 moved AC-1 from $93.32 to $93.15 -- the $0.17 CB-EV-0002
predicted, now collected rather than noted. That is a legitimate
retarget under T07's distinction: the instrument disproved the target,
and its output is in this commit. The number has now been stated five
times ($248.46, $92.21, $92.87, $93.32, $93.15), each correction from a
different mechanism.
Evidence tables regenerated from the tool rather than hand-patched,
per CA-15 -- which is the rule that exists because hand-typed tables
were the only thing the adversarial review found wrong.
