Entry `closing-the-visual-contract`, source_commit d3cd688, covering the
decisions section 19 could not defer: the four system-level rows added to
the shared target-capability table and why no per-object property joins
them, the two automation declaration scopes and their time origins, the
spawn ceiling that refuses where the voice ceiling evicts, the
authoring-bound versus runtime-ceiling distinction behind the centralized
limit table, and the explicit reproducibility exemption for film grain.
The entry states plainly that every runtime ceiling value is an estimate
until the slice 4h benchmark runs, and that no renderer exists.

One entry for the visual contract milestone: why two documentation
slices precede the renderer, the decisions sections 17 and 18 fix, and
what is explicitly not claimed - no renderer, no schema definitions, no
visual fixture, and two user-observed gates still open at the end of
Phase 4.
