ADR-0087 exemption (no-migration-prescription): This diff moves `.objectui-sha` and the artefacts that travel with it (the console changeset, `sdui.manifest.json` + `scripts/sdui-manifest.record.json`, `packages/sdui-parser/objectui-lockstep.json`, and re-measured `.objectui-sha` read-point citations under `packages/spec/src`). 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 declared-breaking entries listed above are objectui's OWN package surfaces, each already carrying its upstream record. Where one of them mirrors an ObjectStack-authorable key, the ledger entry belongs to the `packages/spec` PR that lands the mirror - as `18.ui__ChartConfig__aria`, `18.ui__ObjectGridProps__defaultSort` and `18.ui__ObjectKanbanProps__quickAdd` already do - never to the pin bump, whose diff contains no such key. The tracked `sdui.manifest.json` is generated from PUBLISHED `@object-ui/*`, and the pinned commit declares the same `17.6.0` the old pin did, so this bump moves no declaration-parity reading either. Scope of the claim, stated rather than implied: it is a claim about THIS diff, not a per-entry re-measurement of all 98 upstream declared-breaking entries. The `a472b07167a3...53ded82bf7a4` bump judged its two one at a time; at 98 that is a different exercise and it was not performed here.
