+
+Remove stale source-line citations (`NAME.ext:NNN`) from all 6 published `.describe()`
+schema descriptions in `packages/types/src/zod/complex.zod.ts` (objectstack-ai/objectui#8478)
+— the last file of this card's remainder, which the card now closes.
+
+Text only — no accept-set, key, or shape change. Per-address editorial disposition, not a
+uniform treatment: three descriptions (`FilterBuilderSchema.wrapperClass`,
+`CarouselSchema.itemClassName`, `ChatMessageSchema.avatar` / `avatarFallback`) had their cited
+renderer expression relocated into a maintainer-facing `//` comment beside the schema, since
+the expression only restated what the author-facing prose already said; two
+(`CarouselSchema.opts`, `CarouselSchema.orientation`) kept their expression inline because it
+reveals a real default/policy authors need (`orientation` falls back to `'horizontal'`; `opts`
+is deliberately left open, unnarrowed).
+
+All 6 addresses were spot-checked against the files they cite and are accurate today — no
+drift found, unlike the two prior slices on this card (which found `ObjectKanban.tsx:264`,
+`checkbox.tsx:45/:49` and `text.tsx:162,167` all pointing to stale lines).
