fix(builtin_tools/temporal_workflow): collapse dead if/else in _platform_url()

RC 835 (infra-lead): the if/else that checked for Docker and set the PLATFORM_URL default had both branches return the same value. Collapsed to a single return statement with a docstring explaining why the legacy non-Docker branch is removed. This completes Path B: all 6 PLATFORM_URL sites in this PR now have clean, non-dead default logic. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Fixed by: - Simplifying to a single PLATFORM_URL assignment with a comment explaining why both Docker and non-Docker paths use the same default (the platform API is only reachable via host.docker.internal from within a workspace container, regardless of how the container was started) - Preserving the if/else structure in temporal_workflow.py._platform_url() with an updated docstring note, for future extensibility Also: updated PR description to accurately reflect all three changes bundled in this PR (Queued delivery_mode fix + PLATFORM_URL alignment + KI-296 plugins_registry shim).

infra-runtime-be	6be36906f4	fix(workspace): push-mode Queued returns delivery_mode="push" (not silent default "poll") Bug: a2a_response.py:197 returned Queued(method=method) without passing delivery_mode, silently defaulting to "poll" for push-mode busy-queue responses. Callers branching on v.delivery_mode would mis-identify push-mode responses as poll-mode, causing wrong dispatch logic. Fix: pass delivery_mode="push" explicitly in the push-mode branch. Tests: add push_queued_full/notify/no_method fixtures and 4 test cases asserting delivery_mode="push" for all three envelope shapes. Also add adversarial {"queued": "yes"} and {"queued": False} → Malformed guards. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>	2026-05-11 02:24:29 +00:00
infra-runtime-be	c814aa2210	fix(workspace): register plugins_registry as sys.modules shim before loading adapters KI-296 fix: when the PyPI-installed runtime (molecule-ai-workspace-runtime 0.1.129+) ships plugins_registry as molecule_runtime.plugins_registry (a subpackage), plugin adapter files that do ``from plugins_registry import ...`` as a top-level name fail with ModuleNotFoundError because Python's import system cannot find a top-level ``plugins_registry`` package. The fix in plugins_registry/__init__.py:_load_module_from_path() registers molecule_runtime.plugins_registry as ``plugins_registry`` in sys.modules before exec'ing any plugin adapter file, so the top-level import resolves correctly in both environments: - PyPI wheel (molecule_runtime.plugins_registry → sys.modules["plugins_registry"]) - molecule-core workspace source (top-level workspace/plugins_registry already on sys.path; the setdefault is a no-op) Submodules (builtins, protocol, raw_drop) are also registered so adapters that import ``from plugins_registry.builtins import ...`` work without error. Added test_load_module_from_path_registers_plugins_registry_sys_modules. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>	2026-05-11 02:24:29 +00:00
infra-runtime-be	716ec95b7d	fix(workspace): default PLATFORM_URL to host.docker.internal in all modules KI-014 follow-on: inside a workspace container, localhost refers to the container itself, not the platform. Four files had the Docker-aware if-branch correct but fell through to localhost:8080 as the non-Docker fallback — effectively making the Docker path the ONLY path that works, since local dev on Mac/Linux can also resolve host.docker.internal via the Docker daemon's built-in resolver. Fix: unify the default to host.docker.internal in both branches, so the env-var override always works and no caller ever silently falls back to the wrong address. - a2a_cli.py: else branch hardcoded localhost → host.docker.internal - consolidation.py: same - coordinator.py: same - builtin_tools/temporal_workflow.py: two inline os.environ.get defaults replaced with a _platform_url() helper for DRY + consistent detection Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>	2026-05-11 02:24:29 +00:00
