joule-ui takes in OpenUI Lang 1.0 the way it takes in A2UI: a model writes a
surface as a program, one widget a line, and joule-ui-lang builds a widget tree
against the host's registry as the program streams. After every chunk a snapshot
holds the tree as far as it can be built, each widget checked by joule-ui's own
validate, and every error with its source line and reason code. State, queries,
operators, conditionals, built-in functions and sequences of actions are parsed
and refused not-declarative. A canonical writer turns a tree back into the
language; it parses back to the same tree.
- joule-ui-core: WidgetSchema::positional, the order a positional call passes
props in (SPEC §3); absent from the wire form when undeclared.
- joule-ui-interaction: begin_interaction and Pending::finish, the lifecycle's
three phases in two steps for a host whose handler is asynchronous (SPEC §6);
run_interaction is built on them and seals what it sealed before.
- conformance/lang/v1: L1 statements, L2 ingest, L3 streaming, L4 the canonical
form, L5 refusals, with an independent Python verifier written from §11.
- docs/create.md: the design of Create.
