CB-EV-0007 found three defects in how gates are designed rather than in
any one gate: the meta budget cannot see the pass it governs, it blocks
its own repair, and nothing retires any gate.
D1 budgets measure their own window. D2 a soft breach is a signal, and
repairing the instrument that reports a breach is always in budget — a
gate must never block its own remedy, which is the trap CB-RES-0005 §4
named for session shape and that got built anyway two tasks later. D3
every gate declares what would retire it and a date to argue it on. D4
loop work cashes out into something runnable in the pass that invents
it, from the measured finding that cost per response tracks distance
from a runnable check. D5 the tier table finally covers changes to the
loop's own operation — CB-RES-0005 §6 said a second instance should
trigger it, and this ADR is the second.
The workplan is meta and above the budget line on recorded maintainer
authorization, which is D2's first use.
