Coarsest review cadence: the Builder self-certifies the build phases and the
Adversary does ONE comprehensive cold-verification of the whole accumulated build
in a final `review` phase (vs orig per-phase, lean per-gate). Full original
prompts + a DEFERRED REVIEW CADENCE override, so it isolates verification cadence.
Cheapest coordination; the trade-off is the independent check arrives late (late
rework risk + self-certification drift on build phases). README spells it out.
