Release 1.25.0

What's New

Features

• JSON input method for RIDDL models — A new, correct-by-construction
  way to build a RIDDL model from a structured JSON document, as an
  alternative to parsing RIDDL surface text. RiddlLib.parseJson(json, origin) maps the JSON onto the RIDDL AST, applies RIDDL's required
  type-expression defaults, and returns a Root that the standard passes
  validate and PrettifyPass renders as guaranteed-valid .riddl text.
  A companion RiddlLib.validateRoot(root) validates an already-built
  Root without round-tripping through text. This is intended for
  programmatic and AI-assisted generation: a producer emits JSON (a format
  it handles reliably, and one that supports schema-constrained decoding)
  and RIDDL guarantees the model is well-formed.

  The JSON schema covers the entire RIDDL language — every definition
  (domains, contexts, entities, all processors: adaptors, streamlets with
  inlets/outlets/connectors, projectors, repositories with schemas,
  relationships; sagas, modules and subdomains, epics/use-cases with all
  twelve interaction kinds, and UI groups/inputs/outputs), every type
  expression, the full statement language, functions and methods, and rich
  metadata (descriptions, glossary terms, options, author references,
  attachments, comments). References are emitted as path identifiers and
  resolved by the standard passes, so undefined references surface as normal
  validation errors. The whole path is Native-safe (no I/O; upickle
  cross-compiled for JVM, JS, and Native).

  On the JavaScript/TypeScript side, RiddlAPI.parseJson(json, origin) is
  exposed and documented in index.d.ts. The JSON schema is documented in
  JSON_INPUT.md, with example models under riddlLib/json-examples/, and
  a coverage ledger (JSON_COVERAGE.md) enforced by an automated guard test
  that fails the build if a new AST construct lacks JSON support.

Bug Fixes

• Prettify rendered outputs with a duplicated verb — Output UI
  elements were emitted as invalid RIDDL (e.g. output displays X displays "...") because the prettifier combined Output.identify (which already
  includes the verb alias) with the verb alias again. Outputs now render as
  output X displays "..." and re-parse correctly.

Internal

• Deduplicated RiddlLib's validation-result handling (validateString,
  validateStringQuick, validateRoot, and validateIncremental now share
  common helpers). No behavior change.
• All additions are backward-compatible: no public API was removed or
  changed; parseJson, validateRoot, and the JSON package are new.
