+
+`@object-ui/core` and `@object-ui/data-objectstack` now declare
+`"@objectstack/spec": "^17.2.0"` rather than `^17.0.0`, which is the lowest published
+spec that carries every symbol each package's own build output references
+(objectui#6361).
+
+`packages/core/dist/utils/column-sortability.d.ts` references
+`FIELD_SORTABLE_UNPROVISIONED_ANCHOR`, `FIELD_UNSORTABLE_VIRTUAL_TYPE`,
+`FieldSortability` and `ObjectSortability` from `@objectstack/spec/api`, and
+`packages/data-objectstack/dist/index.js` references the first two — none of which
+`@objectstack/spec@17.0.0` exports. Measured against the published tarballs rather than
+the installed tree, by `scripts/check-spec-range-floors.mjs`: six `floor-too-low`
+findings across the two packages, and `^17.2.0` is that gate's own computed answer for
+both. So the old range was a claim neither package could honour: any consumer
+resolution that lands 17.0.0 — a sibling pinning it exactly, an `overrides` entry, a
+mirror two minors behind — satisfied `^17.0.0` and got a dangling reference.
+
+Nothing a consumer installs today changes: normal resolution already picks the newest
+17.x, and `pnpm-lock.yaml` still resolves `17.2.0` on both edges after the bump — only
+the recorded `specifier:` moves. No source and no behaviour changes, which is why this
+is scored `patch`, on the reasoning objectui#5793 used for the same remediation on
+`@object-ui/plugin-detail`.
+
+The bump is release-blocking rather than cosmetic. `check:spec-floors` is deliberately
+not a `pull_request` job, so every PR stayed green while its blocking copy on the
+publish path — `pnpm changeset:publish` runs it before a single tarball reaches npm —
+would have cancelled the next release.
