The owner's current competence band in one Discipline — derived on read over (Discipline × Transcript), never stored. Bands only: the internal scalar never crosses this surface (the honesty firewall). Returns the floor band without a durable owner key or when disconnected.

Every Discipline the owner has evidence in, with its current band — the read the self-view renders. Disciplines with no evidence are absent (the floor is implicit).

The verb yaml-paths the owner's current competence confers (band × Catalog conferral rules) — the decision behind the knowing→doing seam. CompetenceMixin resolves these to CommandDefinitions and pushes them onto the giver's affordance stack.

The owner-scoped reader. With discipline, returns only that Discipline's rows (the slice the estimator folds). Returns [] without a durable owner key or when disconnected.

Convenience over recordSignature for a single-Discipline world demonstration: forces kind: 'deed'. The shape the practice harness and most one-shot consumer loops use.

The append primitive: explode one authored act into its Transcript rows (one per Discipline sub-check), sharing the act-level kind / when / tags. The signature's disposition channel is ignored (the lane-1 trait seam). No-op without a durable owner key or connection.
