Function PerceptibleMixin

Returns {
    _mixinName: string;
    persistentFields: string[];
    prototype: __type<any>;
    subscribableFields: SubscribableFieldDescriptor[];
    new (...args: any[]): __type;
} & TBase

• • new (...args: any[]): __type

  • Parameters

    • ...args: any[]

    Returns __type

• _mixinName: string

• persistentFields: string[]

  Persistent fields: explicit keywords + the auto-derive opt-out flag + the optional authored primary keyword. Hydrated through the accessor pairs below (Phase 1: setter; Phase 2: bracket- assign via the public-shape setter).

• prototype: __type<any>

• subscribableFields: SubscribableFieldDescriptor[]

  Live-query projection for primaryKeyword. Lives on the mixin (not on Stuff) because the field is mixin-gated: only Perceptible-composed hosts have a keyword pool. The substrate's prototype-chain walk unions this with Stuff.subscribableFields at projection time. Non-Perceptible hosts contribute no primaryKeyword descriptor; the substrate omits the field from their wire records, same shape quantity uses on Globbable.

  dependsOnFields lists the leaf sources: the authored override (primaryKeyword) AND the two fields the derived-pool head folds in (name via NamedMixin, shortDescription via VisibleMixin). Renaming or re-describing a Perceptible host re-projects the keyword surface without an explicit setter call. Shadow-lifecycle support rides on ShadowChangedEvent for parity with displayName.
