This PR upgrades dicechess-bot-java to use com.fortemate:dicechess-bot-runtime:2.0.0, adapting to the new decision-oriented runtime API and dual-key webhook verification.

Changes

  • Dependency upgrade:
    • Bumped <dicechess.bot-runtime.version> from 1.0.1 to 2.0.0 in pom.xml.
    • Updated runtime dependency <groupId> from lv.id.jc to com.fortemate.
  • Strategy interface:
    • Updated imports to com.fortemate.dicechess.runtime.*.
    • Made Strategy extend BotStrategy, implementing onTurn(TurnContext) with new TurnAction(chooseMoves(context)) while retaining single abstract method chooseMoves(TurnContext) for functional implementations.
    • Inherited safe default decision handlers (onDrawDecision, onDoubleOpportunity, onDoubleDecision).
  • Main server & WebhookKeys:
    • Updated imports to com.fortemate.dicechess.runtime.*.
    • Added resolveWebhookKeys() supporting DICECHESS_WEBHOOK_SECRET and DICECHESS_WEBHOOK_NEXT_SECRET with fallback placeholder and logging.
    • Added overloaded Main.start(...) helper methods.
  • Documentation & Package info:
    • Updated README.md and package-info.java references to com.fortemate:dicechess-bot-runtime and dual-key rotation.
  • Tests:
    • Updated OnnxStrategyTest.java to use the v2 TurnContext constructor and verified onTurn, null context, and invalid DFEN handling.
    • Extended WebhookIntegrationTest.java with tests for verification handshake, signed yourTurn webhook delivery, invalid HMAC rejection, and health endpoints.

Verification gates run

  • mise run format (Spotless)
  • mise run check (all 15 unit and integration tests pass, shaded JAR built successfully)

Summary by CodeRabbit

  • New Features

    • Added support for active and pending webhook secrets, enabling zero-downtime secret rotation.
    • Updated bot strategy integration to support turn actions and optional decision handling.
    • Added webhook verification, signed delivery, health-check, and root endpoint support.
  • Documentation

    • Updated integration guidance, environment variable references, and custom strategy examples.
  • Tests

    • Expanded coverage for webhook authentication, key resolution, endpoint behavior, and strategy decisions.

📝 Walkthrough

Walkthrough

The bot now uses dicechess-bot-runtime v2. Strategy integrates with BotStrategy. Webhook authentication supports active and pending secrets. Main resolves keys and starts the server through new overloads. Tests cover runtime actions and webhook flows.

Changes

Runtime and webhook integration

Layer / File(s) Summary
Runtime v2 and strategy contract
pom.xml, src/main/java/com/fortemate/dicechess/bot/Strategy.java, src/main/java/com/fortemate/dicechess/bot/OnnxStrategy.java, README.md, src/main/java/com/fortemate/dicechess/bot/package-info.java
The project uses runtime v2 under the com.fortemate namespace. Strategy extends BotStrategy and converts selected moves into TurnAction.
Webhook key resolution and server wiring
src/main/java/com/fortemate/dicechess/bot/Main.java, README.md, src/main/java/com/fortemate/dicechess/bot/package-info.java
Main resolves active and pending webhook keys, provides start overloads, and falls back to unconfigured-secret when key configuration is invalid. Documentation describes DICECHESS_WEBHOOK_NEXT_SECRET.
Runtime and webhook integration tests
src/test/java/com/fortemate/dicechess/bot/OnnxStrategyTest.java, src/test/java/com/fortemate/dicechess/bot/WebhookIntegrationTest.java
Tests cover the updated TurnContext, TurnAction results, default decisions, verification, signed delivery, invalid signatures, health and root endpoints, and key resolution.

Merge Risk: 🟠 High · up to 7101f

A deployment configuration error exposes a publicly known signing key, allowing unauthorized webhook actions. Startup should fail closed before merge.
