From c5a92b6fe166a3f4a70425f733f5a9551b97d1a7 Mon Sep 17 00:00:00 2001 From: perplexity Date: Sun, 22 Mar 2026 11:59:19 +0000 Subject: [PATCH] feat: WorldInterface abstraction + Heartbeat v2 loop (#871, #872) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a Gymnasium-style WorldInterface ABC at src/infrastructure/world/ with adapter registry, MockWorldAdapter for testing, and TES3MP stub. Wire the interface into a new Heartbeat v2 loop (src/loop/heartbeat.py) that drives observe→reason→act→reflect cycles through whatever world adapter is connected, with graceful fallback to passive thinking when no adapter is present. Enrich Phase 1 (Gather) with world observations. Includes 63 passing tests covering interface contracts, all adapters, registry, heartbeat cycles (embodied + passive), and WS broadcast.
