58The prelude also has a Jibb-written `zing` that concatenates homogeneous lists via `weld`. Its focused golden infers empty, nested text, ship, generic and gate-element lists and reports a non-list error; the same golden passes on the ship. A Hoon translation agrees with Hoon `zing` on selected finite inputs, not on Jibb execution. Hoon’s raw helper additionally accepts heterogeneous noun lists, which the Jibb signature does not express. Backend lowering and jet recognition remain unverified.

60+The experimental deferred constructor transaction conservatively declines tuples, branches, field reads, nonidentical successful call/cast fits, and multi-argument calls with open argument, sample or result types. This prevents a later substitution from invalidating an earlier face-propagation check; cases requiring deferred structural fits remain unsupported. Focused regression checks exercise both source orders and independent polymorphism.
60The checked inference slice now represents `!!`, proves empty cell positions and filters proven-empty union cases. List and unit payload arms whose elements are empty are rejected as unreachable; fixed opaque cases fail closed when reachability is unknown. The new shared guard covers checked interfaces, partial diagnostics and proof budgets. Its evaluator is run separately; ship verification remains pending.

62An eval and ship fixture now reports partial inference for the unchanged todo island with its real API and Hoon readers. It verifies that the source fixtures match `my-app` and exercises missing or duplicate imports; the report does not claim the module or island has been checked. The prelude also has a Jibb-written recursive `lent` whose supported generic calls infer `@ud`. Execution and shape-based jet recognition remain future backend work. Nested union tests check equal runtime nouns, different nested tags, empty fields and unknown inhabitation.
