+No package released: test pins only, no behaviour change. `@objectstack/spec` 18 adds an optional `kind` (`'open' | 'won' | 'lost'`) to `SelectOptionSchema` (objectstack#23846). `@object-ui/types` derives the spec's keys by reference, so both select-option faces carry it with no source edit. The tier-1 convergence pins in `select-option-tier1-convergence-7014.test.ts` now state `kind` as a deliberate optional widening. They name it through a key read off the spec's own type, so they hold against the installed spec and objectstack `main`'s alike (objectui#12711).

  *
+ * ## ⭐ What `@objectstack/spec` 18 changed here, and why it is written as a widening
+ *
+ * Spec 18 adds an OPTIONAL `kind: 'open' | 'won' | 'lost'` to
+ * `SelectOptionSchema` (objectstack#23809, landed as objectstack#23846): the
+ * option's lifecycle category. It arrives on both faces by reference, exactly as
+ * `description` did, so the gained-key sets below are `'description'` /
+ * `'default'` PLUS `kind`. That is a deliberate optional widening, stated here
+ * rather than absorbed: the `PRE_CONVERGENCE_*` records are not edited, and
+ * `kind` is not `Omit`ted from either face.
+ *
+ * `kind` is spelled through {@link SpecKindKey}, which is `'kind'` when the spec
+ * in use declares it and `never` when it does not, read off the spec's OWN type
+ * rather than a version check. The repo's `Type Check` compiles against the
+ * installed spec and objectstack's hourly Spec Shape Gate against the spec built
+ * from objectstack `main`, and these pins must hold on both until the two meet.
+ * Any OTHER key the spec adds still turns every set difference red.
+ *
+ * The form face keeps `kind` although the spec's form-VIEW options
+ * (`FormSelectOptionSchema`) leave it out: this face was never that schema (it
+ * has carried `default`, which that schema also leaves out, since before the
+ * convergence), its zod twin spreads the same spec shape, and whether the form
+ * face should drop either key is a face change of its own (objectui#12711).
+ *
  * ## The control the spec fixtures need
  *
  * A select option's `value` is a lowercase machine identifier with a minimum
