ADR-0087 exemption (no-migration-prescription): This diff moves `.objectui-sha` and the artefacts that travel with it: this console changeset, the regenerated `sdui.manifest.json` and its record `scripts/sdui-manifest.record.json`, the re-recorded `packages/sdui-parser/objectui-lockstep.json` (its grammar region, diagnostic codes and containment predicate are unchanged across the range) and the re-measured pin citations in `packages/spec/src`, which carry their own `@objectstack/spec` patch changeset. It adds, removes or renames no ObjectStack-authorable key: no Zod schema, no spec declaration and no stored `sys_metadata` shape moves in it, so `objectstack migrate meta` has nothing here to rewrite, and this body carries no FROM/TO prescription of its own. The manifest is the one accept set that moves, and it moves in one direction. Its `element:repeater` row loses the `object` (required), `filter`, `sort` and `limit` inputs and its `element:number` row loses `object` and `filter` (objectui#12085, `ce991bd70`), the html tier's half of the retirement `@objectstack/spec` already carries with its own disposition (`element-flat-data-binding-retired`, #11509). Measured with `compile()` of `@objectstack/sdui-parser` against both manifests: a repeater bound through `dataSource` alone goes from `missing-required-prop` (error) to clean, and the flat keys go from clean to `unknown-prop` (warning, which the save gate does not refuse). Nothing that passed before is refused now. The range carries one declared-breaking objectui change, by its author's breaking annotation and not by a declared `major`: objectui#6349 batch 10 (`12ff25631`), the row type of `@object-ui/plugin-designer`'s `VersionHistory` timeline is declared as `VersionHistoryEntry` instead of `VersionEntry`. An objectui TypeScript type; no ObjectStack key. No commit subject in the range carries `!`.
