From b6c49da8931c155bf6cf35468ef187a827796d84 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Fri, 30 Jan 2026 00:37:33 +0000 Subject: [PATCH] feat(adk): Implement ApiRegistry and test dynamic discovery compliance - Implemented `ApiRegistry` in `src/vertice_core/adk/registry.py` with resilient discovery logic (graceful degradation in non-GCP environments). - Updated `VerticeAgent` in `src/vertice_core/adk/base.py` to instantiate `ApiRegistry` during initialization. - Added unit tests in `tests/unit/test_api_registry.py` to validate `ApiRegistry` behavior and its integration with `VerticeAgent`. - Fixes Issue #65 [JULES-003].
