Format Specification section 18 (PRD 77-84) closes slice 4b: visual
components and their inputs scope, particle systems with a normative
integrator and life ramps, the nine placement distributions, emitters
with exact fractional-accumulator emission timing, repeaters and the
copy-scoped repeat.* namespace, the seventeen-behavior vocabulary and
its channel set, the six procedural fields with a normative coherent
noise function, and trails, ribbons, and links.
Seven diagnostic codes are added to the section 7 table. Section 17 is
amended in four places the new section requires: the visuals.fields
container, the component visual object type beside the closed fourteen
primitives, the now-declared behaviors field, and the widened visual
limit row. Revision 0.5 -> 0.6.
Documentation only; no runtime, schema, fixture, or test file changed.
npm test remains 102 passing.

Open the Visual subsystem contract at Format Specification revision 0.5 with
section 17, covering PRD 69-76: the renderer-neutral pipeline, canonical units
on a single degrees convention, the visuals container, layers, the scene model
with three coordinate spaces and three fit modes, 2.5D depth with a fixed sign,
stable sorting, parallax, perspective factor and per-object fog, the fourteen
primitives of Visual Primitive Set 0.1, common visual properties, a normative
transform composition order, appearance with the eight-mode safe blend set and
gradient paint, paths and splines with independently addressable points, text
restricted to the three generic font families, and the once-at-instantiation
resolution boundary for visual ValueSpec fields.
Visual objects are keyed rather than listed and carry no id field, matching the
audio node-identity rule that a Phase 3a blocking defect established. No visual
property becomes externally addressable in this slice; a binding, set, or
override naming one remains ERR_UNSUPPORTED_TARGET, and section 8.1 is
unchanged until section 19.1 adds its rows.
Add five diagnostic codes to the section 7 table, record the eight-slice Phase 4
delivery plan, mark the section 11 Visuals register row in progress, and refresh
the implementation status, which had not been updated since the 3c-1 contract.
Documentation only; no runtime, schema, fixture, or test file is touched.
npm test passes 102 tests with zero failures.
