diene_api_engine

The generic, pure-Dart library template for the Diene family. It ships a small, replaceable sample domain — a Note value type with a JSON wire codec and a pure summariser — inside the reusable template machinery (strict analysis, targeted coverage, a dependency-light TestHelper, a C0 fixture harness, package hygiene, and a shipped usage skill).

import 'package:diene_api_engine/diene_api_engine.dart';

const Note note = Note(title: 'Release', body: 'Ship the template.');

final String summary = summarizeNote(note);        // 'Release — Ship the template.'
final Note decoded = Note.fromJson(note.toJson());  // round-trips through JSON

Public surface

• Note — immutable title/body value type with value equality and a JSON wire codec (Note.fromJson / toJson).
• summarizeNote(note, {maxLength}) — a pure single-line summariser.
• defaultSummaryLength — the default summary cap.

TestHelper

Consumer tests may import package:diene_api_engine/test_helper.dart for assertNoteSummary, a dependency-light assertion that throws NoteAssertionFailure on mismatch and pulls in no test framework.

Read the package doc for the full API, wire contract, C0 harness, and guidance on replacing the sample.

Using this template

This is a template: a materialized child retokenizes the package identity to diene_<name> / AtomiCloud/diene.dart_<name>, replaces lib/src/** with its own domain, and re-points the barrel exports. See skills/diene-api-engine-usage/patterns.md.

Development

• pls setup resolves the workspace dependencies.
• pls test runs the unit, C0 conformance, and TestHelper meta suites.
• pls test:coverage enforces the separate unit and meta ledgers.
• pls deadcode runs the repository and production-only dead-code passes.
• pls package:validate runs the release guard, publish dry-run, and pana.
