Publishes what the tool guarantees, on a condition that fired rather than a
decision reversed. Records the narrower promise that replaced promising the command
surface — a change to it lands on the page consumers already lock, so a rename
reports 200 the day it happens.
And records a limit found by accident that follows from a guarantee rather than
from anybody's code: an ETag is opaque, we promise never to interpret one, so two
of them can be compared and never ordered. A consumer can know two versions
disagree and can never know which is behind. Anybody building freshness on this
inherits it.
