Origin: the designed-and-measured remainder of #11601 (PR #12309). Filed by the PM on the dev's behalf (recording only — unassigned, awaiting triage).
What is left: PR #12309's nested-shape sub-tables deliberately refuse a property row that opens two or more object shapes (no single shape to name — mirroring formatPropertyType's refusal to relocate out of an array-of-enum). Census: 28 such rows, e.g. ui/App.navigation (9 variants), ui/NavigationArea.navigation, ui/NavigationContribution.items, data/ConditionalValidation.then / .otherwise (5 each). Their nested .describe() text still never reaches the reference page.
Shape of a follow-up: render one sub-table per variant under a variant-indexed heading (the accessor grammar PR #12309 introduced extends naturally — e.g. a discriminant-keyed spelling). Cost is bounded by the census: 28 rows repo-wide. Also adjacent, recorded on the same run: describes below level 1 stay unreachable by design (SHAPE_DEPTH_LIMIT=1; unbounded contrast reading: 22,459 occurrences vs the 7,502 level-1 ones #12309 publishes) — a depth widening is a separate, bigger decision and is NOT what this card proposes.
Dedup (searched 2026-08-25): only #11601 itself matches; no open card covers the multi-shape remainder.
