Eve Two-Consumer Counter

This is the smallest executable package-consumer checkpoint for CultMesh plus Eve. It intentionally has one owner for each decision:

• the provider node owns the counter document and command transaction;
• Eve owns the validated surface and command-receipt contracts;
• CultMesh owns typed observation and the operation boundary;
• the DOM lowerer owns HTML only;
• the headless observer owns no state.

Run it from the CultLib repository:

pwsh -File ./scripts/verify-eve-getting-started.ps1

That command continues into the real Chromium/C# network checkpoint after this artifact layer passes. Run verify-eve-two-runtime-sample.ps1 directly only to diagnose clean package consumption in isolation.

From clean CultLib and Eve checkouts, the verifier installs missing build dependencies, builds package artifacts, installs them into a new empty temporary consumer, and runs sample.mjs. Success proves:

1. no source-tree import is required by the consumer;
2. the provider surface and receipt pass Eve's generated runtime validators;
3. a DOM click executes one idempotent provider operation;
4. the DOM binding and a separate headless observer converge on the same count;
5. the canonical receipt and state survive reopening the .cc store.

This is not yet the promised networked multiplayer tutorial. The DOM lowerer is hosted by jsdom in Node and both consumers share one local CultMesh node. A real browser transport, Odin discovery, process separation, and a second language runtime require distinct executable gates. Keeping that limitation visible is part of the sample contract.
