Nothing left from the reviewers scored high enough to earn a roadmap item, so
the four discards are written down with their reasons instead — a discard whose
reason is missing comes back next session dressed as an obvious win. The one
worth keeping is the enrollment toast's third spelling of the failure copy: it
is deliberate, because that toast has no retry affordance and ending the
sentence in "Tente novamente." would be a false instruction.
Three engineering deferrals gained the trigger they lacked (shared HMAC core,
an optional `bodySchema` on the route shell, promoting `postJson`) — all three
are second-call-site abstractions, so the trigger is the third.
Also corrects two statements this delivery falsified: the notebook still said
`postJson` translates `SyntaxError`, which the simplify pass deleted, and the
roadmap's B40 item carried the pre-optimization 130 kB that its own header line
had already restated as 126 kB.
