The normative coherent noise of 18.7 (ordered gradients, a 255-sample
Fisher-Yates permutation, octave normalization, and curl as the explicit
perpendicular of the potential's gradient, with published tolerances), the nine
distributions with their normative draw-order table, all seventeen behaviors
with their field contracts and the accumulating-versus-fresh split, component
expansion independent of group nesting depth, particles, emitters, repeaters,
trails, and links. Traces 1 through 19 of 18.10 are automated.
The renderer core this builds on is corrected here rather than separately,
because 4e is what exercises it: the production render path now passes a real
compositing surface factory, so a masked group or a non-opaque layer composites
instead of throwing and permanently deactivating the visual subsystem;
system-level `behaviors` arrays run `validateBehaviors` at import with field
context, so the six classes of invalid document that used to fail at activation
now fail where an author can see them; velocity-accumulating behaviors integrate
on object and repeater hosts; `morph` guards both sides of the z delta rather
than poisoning perspective projection with NaN; `face-motion` initializes its
follow state lazily and holds the previous rotation at zero velocity; a `ring`
with equal start and end angles draws nothing instead of a radial spoke; a
resolved non-integer creation count raises ERR_TYPE_MISMATCH at the boundary
instead of being rounded; boolean leaves are type-checked; per-type required
fields and the static half of the unbounded-emission rule are enforced at
import; and a repeater rejects the emitter-only fields 18.5 says it has none of.
A duration is now the authored literal or a non-negative finite number already
in milliseconds, resolving the one design question the review triage left open.
Runtime, validator, and specification agree on it.
A guard test asserts that no two bundled modules declare the same top-level
identifier: the bundler concatenates into one scope, so a private helper name
collision is a SyntaxError in the artifact while every unit test still passes.
