ADR-0087 exemption (no-migration-prescription): All TWO declared-breaking entries in the range `a472b07167a3...53ded82bf7a4` are judged ONE AT A TIME against `packages/spec`'s authorable surface at this HEAD, re-measured here rather than quoted from upstream prose. (1) objectui `446d93d4e` (objectui#6972) retires `MarkdownSchema.sanitize` and `MarkdownSchema.components` as ADR-0049 tombstones on objectui's OWN SDUI `markdown` node. That node is not an ObjectStack-authorable component: `MarkdownSchema` has ZERO occurrences under `packages/spec`, its single hit anywhere in `packages/` being one line of published history in `packages/console/CHANGELOG.md`; and `sanitize` occurs ZERO times as an authored key in `packages/spec/src` — its five textual hits are a namespace-charset helper, two SQL-injection docblocks and one `view.zod.ts` refusal message, none of them a schema member. The `markdown` spelling this repo DOES declare is a data FIELD type (`packages/spec/src/data/field.zod.ts:2263`, `data/field-value.zod.ts:58`) — a long-text field kind that carries neither retired key. No accepted ObjectStack key moves and no stored `sys_metadata` row can carry either spelling. (2) objectui `bc640ec56` (objectui#7645) narrows the VALUE side of one entry in `@object-ui/types`' `SchemaRegistry` type map to `BaseSchema & { type: 'kanban' }`; upstream states `keyof SchemaRegistry` and the published `ComponentType` union are unchanged. This repo's own `SchemaRegistry` shares the NAME and nothing else — all 16 files matching it under `packages/spec/src` are ObjectStack's metadata-registry contract surface (`contracts/metadata-service.ts`, `contracts/objectql-engine.ts`'s `EngineSchemaRegistryView`, the error-code ledger), never objectui's component-type map, and `packages/spec/src` imports from `@object-ui/*` ZERO times. `KanbanSchema` has 2 occurrences under `packages/spec/src` and BOTH are prose — a comment at `ui/component.test.ts:2783` and a docblock at `ui/component.zod.ts:2679` — neither a declaration nor an import. Neither entry is reachable through `@objectstack/console` in any case, re-measured against `packages/console/package.json` at this HEAD: it publishes a frozen prebuilt SPA whose `files` list is ["dist", "README.md", "CHANGELOG.md"], whose sole `exports` entry is `./package.json` and whose `dependencies` are empty, so it forwards no `@object-ui/*` module entry point and re-exports none of these types; and no `package.json` in this workspace declares an `@object-ui/*` dependency at all (0 files, re-measured). This diff is `.objectui-sha`, this changeset, the four `packages/spec/src` sources whose objectui pin CITATIONS the bump refreshes — comment-only, and measured so: the base and head versions of all four compile to AST-identical output under TypeScript with `removeComments`, which string literals survive, so no describe text, alias or tombstone literal moved — and the two generated pin records the bump gates require (`scripts/sdui-manifest.record.json`, `packages/sdui-parser/objectui-lockstep.json`). No `packages/spec` schema, no authorable metadata key and no protocol surface changes in it — so there is no stored-metadata rewrite for `objectstack migrate meta` to prescribe and therefore no ADR-0087 ledger entry to write or to name from THIS bump. This bump adds no ledger entry and claims none.
