ADR-0006 D1. cb-cost gains pass_costs, which buckets responses into
workplan windows in a single read of the transcripts — calling collect()
once per boundary would re-read every transcript per window, and status
is supposed to stay cheap enough that nobody replaces it with ls.
make status now reports the share over a trailing three passes with the
per-pass breakdown, keeps the lifetime figure labelled NOT the metric,
and prints the D2 exemption so the next reader does not re-derive the
standoff where the budget blocked its own repair. One pass would be a
coin flip: a meta pass reads 100%, a product pass 0%. Three is the
smallest window where the ratio means something and still moves.
First reading: 36% over the last three passes against 49% lifetime,
with CB-WP-0008 at 0%.
The first run reported $0.00 for every window. Transcript stamps are
UTC Z and git prints a local offset, so the string comparison put every
response before the first boundary. Both the fix and a self-test for it
are in; reverting the conversion turns four checks red.
