Module compose 

CRUDUI composition engine — SPEC §5, G5.

The parser’s first pass: expand $ref (base inheritance) then $patch (add/remove/replace + deep-path set) into a single, composition-free spec, BEFORE the field layer / validation / render. Unresolved composition is a LOAD ERROR (ComposeLoadError) — never valid:true.

Byte-for-byte parity with the JS reference engine (packages/validator/ts/src/compose); the shared 4-language fixture tests/fixtures/compose/cases.json is the single source of truth.

Modules

compose

Composition orchestrator (SPEC §5, G5) — the parser’s FIRST pass.

errors

Composition load errors (SPEC §5, §7; unresolved_behavior).

loader

File loader for $ref resolution.

member_order

Specification member order (docs/spec/schema.md, “Member order”).

patch

$patch application — add / remove / replace over the $ref base (SPEC §5). There are no $after/$before/$merge/$change/$remove directives; $patch is the only overlay.

ref_

$ref resolution expands base inheritance before other composition (SPEC §5).
