Make the LLM quota matcher exhaustive for basedpyright and expand unit coverage across quota resolution and deduction branches. This addresses the failing Python style/type gate and raises patch coverage for the Graphon 0.3.0 upgrade branch.
Treat missing public model identity on quota-tracked workflow nodes as an execution bug instead of silently skipping quota handling.
Abort the workflow for both pre-run and post-run identity lookup failures and extend the layer tests to assert the stop-event and abort-command behavior.
Remove the temporary generic model-type quota helpers now that system-billed models are LLM-only.
Keep the deprecated ModelInstance wrappers as LLM-specific adapters with explicit non-LLM guards and update the quota tests to match the narrower invariant.
Add model-type-aware quota helpers at the shared billing boundary while keeping the LLM-specific helpers as thin adapters.
Preserve model_type in the deprecated ModelInstance wrappers and extend the quota unit tests to cover the generic helper delegation path.
Introduce tenant-scoped quota helpers that accept provider and model identity directly.
Refactor the workflow quota layer and engine wiring to use public node and event model identity instead of reconstructing ModelInstance, and keep the legacy ModelInstance helpers as deprecated wrappers with focused test coverage.
Repair the plugin model runtime for Graphon 0.3.0 by implementing structured-output support, normalizing non-stream LLM calls, and tightening workflow-layer type safety.
Update the remaining workflow tests to use VariablePool.from_bootstrap(...) and the new node data constructor API so the CI unit and integration suites match the upgraded runtime behavior.
Adapt the backend Graphon integration to the v0.3.0 breaking changes.
Migrate provider factory and runtime usage, switch workflow node construction to the new data payload API, and refresh backend tests for the updated VariablePool and node behaviors.
