ADR-0087 exemption (no-migration-prescription): This diff moves `.objectui-sha` and the artefacts that travel with it: this console changeset, the re-recorded `scripts/sdui-manifest.record.json` and the regenerated `sdui.manifest.json`, and the re-recorded `packages/sdui-parser/objectui-lockstep.json`. It adds, removes or renames no ObjectStack-authorable key: no Zod shape, 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 range carries three objectui changes their authors annotated breaking, and the digest marked all three. Each is answered against this tree: (1) objectui#12486 (`f8267df93`), `@object-ui/types`: `PageNodeSchema.kind` drops `jsx` and the page renderer stops compiling it as `html`. `@objectstack/spec` here already refuses page `kind: 'jsx'` at parse (`packages/spec/src/ui/page.zod.ts`), so no page this tree accepts reaches that arm. (2) objectui#12627 (`608033b82`), `@object-ui/components`: `page:header` stops reading `showStar`. `@objectstack/spec` here already retires the key; its conversion is the registered `page.component.page:header.showStar` entry in `packages/spec/src/conversions/registry.ts`. (3) objectui#12504 (`3eb3ec138`), `@object-ui/types` and `@object-ui/data-objectstack`: `DataSource.updateViewConfig` and its capability gate are removed. No package or example here depends on any `@object-ui/*` package; the name survives in this tree only in two test comments and one checklist step, none of which calls it. Scope of the claim, stated rather than implied: it is a claim about THIS diff, not a per-entry re-measurement of the upstream declared-breaking entries.
