Provenance (tier S, structural L, chaos d4=4 -> S). First fire of the
chaos mechanism in six declarations. The structural trigger was L
(stage 1 creates a rendering port); the roll overrode it to S, which
has no ADR. Rather than lawyer the hard 'no code before ADR' gate in
either direction, the declaration is split: this packet takes the part
of stage 1 that creates no port and adds no dependency, and the port
half keeps its own declaration and its own roll.
AM-4a supports that ordering independently -- 3,750 lines of headroom
against a 250,000 target means any toolkit choice needs the survey the
roll just deleted.
Finding acted on: cb-play's render() drops ~a third of GroundView,
including the whole DARVO and GROUND-practice state.
