Format Specification revision 0.7 adds section 19, the third and final
visual contract section, covering PRD 85-89 and 119-120.
Visual automation reuses the audio track shape of 16.1 and adds only
`loop`. It is declared in two scopes: `visuals.automation`, measured from
activation, and `visuals.systems.<id>.automation`, measured from that
system's instantiation boundary, so a track on a spawned system behaves
identically however late the spawn happens.
Section 8.1 gains exactly four visual rows, all system-level: camera
fields, layer opacity, system visibility, and post-effect parameters. No
per-object geometry, transform, or style property becomes externally
addressable in 0.1, so the statements in 17.14 and trace 19 of 18.10
survive unchanged. This is the decision 17.14 and 18.6 both deferred.
Systems are persistent or spawned by an explicit `lifecycle` enum. A
spawned system is a template, instantiated only by a spawn action, with a
five-state machine plus FAILED, a `0ms` default release, and a spawn
ceiling that refuses rather than evicts.
The camera matrix is normative, including that parallax multiplies the
camera translation only. `projection` is authored once and is neither
automatable nor bindable.
Seven post-effects, applied in normative array order with a stated
approximation boundary. `grain` is explicitly exempt from reproducibility
and consumes no procedural stream.
Section 19.5 is the centralized ceiling table PRD 120 requires. It
separates authoring bounds, which reject an exhibit at import, from
runtime ceilings, which shed work by a documented deterministic rule and
keep the exhibit running, and it restates every ceiling first fixed in
sections 10 and 14 through 18. Its aggregate values are provisional
pending the slice 4h GC6 measurement.
Two diagnostic codes added: ERR_INVALID_EFFECT_TYPE and
WARN_VISUAL_CEILING. ERR_AUTOMATION_CONFLICT widens to cover a visual
scope and the behavior collision rather than minting a second code.
Documentation only: no runtime, schema, fixture, or test file was
touched. The visual contract now contains no unresolved forward
reference, and npm test still passes 102 tests with zero failures.
