ADR-0087 exemption (no-migration-prescription): This diff moves `.objectui-sha` and the artefacts that travel with it: this console changeset, `sdui.manifest.json` + `scripts/sdui-manifest.record.json`, the re-recorded `packages/sdui-parser/objectui-lockstep.json` 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 43 declared-breaking entries listed above (26 commits) are objectui's OWN package surfaces, each already carrying its upstream record: `6f5719e1c` and `c73cdb569` (objectui's `object-grid`, `list-view` and `object-kanban` validators take only the `{ condition, style }` rule `@objectstack/spec`'s `ListViewSchema.conditionalFormatting` already declares), `160c6c6ea` (objectui's dashboard renderers draw the retired-format placeholder for a dataset-less `provider: 'object'` single-value widget, a form the ObjectStack dashboard widget schema has refused since 9.0.0 by requiring `dataset`), `9ed8d0f1c` and `8366accd1` (two drill-report forms on objectui's own `DrillDownConfig`), `2d576e46e`, `aea682a31`, `4abc0aafa` and `3f6efd640` (objectui's `grid`, `stack`, `flex` and `container` layout nodes: the flat breakpoint `*Columns` keys and the `columns`, `gap` and `padding` value sets), `37268aae9`, `ea3914139`, `1fe05ff37` and `9de0b3483` (four `@object-ui/cli` retirements), `9d9ed5495` (three entries: objectui's `spec-report` node key, its lazy stub and its known-types row), `fcdc8ec91` (objectui's `app-schema-renderer` node), `0d723a33f` (objectui's `ObjectGridSchema` zod mirror), `f560ded15` (objectui's percent faces scale at the storage the field declares, through `@objectstack/spec`'s own `percentScaleOf`), `ca3de7272` (objectui's `SidebarSchema`), `1c8403692` and `9d1c0bff9` (four entries: objectui's ten `sidebar-*`, `navigation-renderer` and `responsive-grid` node keys and their known-types rows), `5988b6b53`, `0e9058b95` and `c4ab6d09a` (five entries: objectui's `@object-ui/plugin-designer` registrations, members and props; `onDelete` is respelled `deleteBehavior`, the spelling ObjectStack's lookup fields already use), `ad1785c1d` (five entries: objectui's `pie-chart`, `donut-chart`, `radar-chart` and kebab `page-header` node keys, whose protocol spellings are `chart` + `chartType` and `page:header`) and `37140f4f5` (nine entries: twelve more objectui node keys — `scatter-chart`, `dashboard-grid`, the bare `metric` / `metric-card` fallbacks, four builder-chrome keys, `form-analytics`, `import-wizard`, `related-list` and `shared-view-link` — and their stubs and known-types rows). None of these keys is a member of `@objectstack/spec`'s `PageComponentType` or a `ComponentPropsMap` row; a stored ObjectStack page that names one reaches it only through `PageComponentSchema.type`'s open string arm, as the previous bump's retired bare `tree` / `view` keys did. Where an entry mirrors an ObjectStack key, the ledger entry belongs to the `packages/spec` PR that lands the retirement, never to the pin bump. Scope of the claim, stated rather than implied: it is a claim about THIS diff, not a per-entry re-measurement of the 43 upstream declared-breaking entries.
