Bug Report: error-handling — `PlanExecutor._guard_execute()` references non-existent `plan.state` attribute

Severity Assessment

Impact: Every attempt to run the Execute phase via PlanExecutor will fail with an AttributeError when the plan's processing state is anything other than QUEUED. The guard is meant to reject non-queued plans, but due to the wrong attribute name it may either silently pass bad plans through (if plan.state resolves to something truthy via __getattr__) or crash immediately with AttributeError.
Likelihood: Always triggered. The Plan domain model exposes processing_state, not state. This bug was introduced when attribute naming was standardised.
Priority: Critical

Location

File: src/cleveragents/application/services/plan_executor.py
Function/Class: PlanExecutor._guard_execute
Lines: 781–798

Description

The _guard_execute() method checks three pre-conditions before allowing execute to proceed. The second check compares plan.state against ProcessingState.QUEUED. The Plan domain model does not have a .state attribute — the correct attribute is .processing_state. This means:

If Plan has no __getattr__ fallback, every execute attempt raises AttributeError.
If Plan does have a fallback returning a falsy value, the guard always blocks execution with a confusing error message referencing the wrong attribute value.

Evidence

def _guard_execute(self, plan_id: str) -> Any:
    plan = self._lifecycle.get_plan(plan_id)
    if plan.phase != PlanPhase.EXECUTE:
        raise PlanError(...)
    if plan.state != ProcessingState.QUEUED:          # BUG: should be plan.processing_state
        raise PlanError(
            f"Plan {plan_id} is not queued for execution (current: {plan.state})"
        )
    if plan.decision_root_id is None:
        raise PlanError(...)
    self._enforce_guardrails(plan_id)
    return plan

Every other reference to the plan state in the codebase uses plan.processing_state (e.g., plan_apply_service.py, plan_resume_service.py, subplan_execution_service.py). The Plan domain model field is named processing_state.

Expected Behavior

The guard should check plan.processing_state != ProcessingState.QUEUED using the correct attribute name, rejecting plans that are not queued for execution.

Actual Behavior

plan.state raises AttributeError (or returns an unexpected value), causing every execute-phase entry via PlanExecutor._run_execute_with_stub() and _run_execute_with_runtime() to fail before execution begins.

Suggested Fix

def _guard_execute(self, plan_id: str) -> Any:
    plan = self._lifecycle.get_plan(plan_id)
    if plan.phase != PlanPhase.EXECUTE:
        raise PlanError(
            f"Plan {plan_id} is not in Execute phase (current: {plan.phase.value})"
        )
    if plan.processing_state != ProcessingState.QUEUED:   # fix: use processing_state
        raise PlanError(
            f"Plan {plan_id} is not queued for execution "
            f"(current: {plan.processing_state})"
        )
    if plan.decision_root_id is None:
        raise PlanError(...)
    self._enforce_guardrails(plan_id)
    return plan
