Summary

PlanExecutor accepts a fix_revalidate_orchestrator parameter and stores it as self._fix_revalidate_orchestrator, but this orchestrator is never invoked anywhere in the execute flow. The fix-then-revalidate loop — which is supposed to automatically fix required validation failures and retry — is completely non-functional.

What Was Tested

Code-level analysis of src/cleveragents/application/services/plan_executor.py
Grep for all usages of _fix_revalidate_orchestrator in the file

Expected Behavior (from spec §Validation Failure Handling)

When a required validation fails during Execute:

The execution actor diagnoses the failure
Attempts to fix the underlying issue within strategy constraints
Re-runs the failing validation
Repeats up to max_retries times (default 3)
If still failing: escalates to strategy revision or user escalation

The FixThenRevalidateOrchestrator.run_fix_loop() is the implementation of this loop.

Actual Behavior

# plan_executor.py — all usages of _fix_revalidate_orchestrator:
# Line 365: self._fix_revalidate_orchestrator = fix_revalidate_orchestrator  (stored)
# Line 422: return self._fix_revalidate_orchestrator  (property getter)
# 
# NEVER called in _run_execute_with_stub() or _run_execute_with_runtime()

The orchestrator is injected via dependency injection and exposed as a property, but no code in the execute flow ever calls self._fix_revalidate_orchestrator.run_fix_loop(...).

Impact

Required validation failures are never automatically fixed
The retry loop (up to 3 attempts per spec) never runs
Plans with fixable validation failures immediately fail instead of attempting recovery
The FixThenRevalidateOrchestrator implementation (which is complete and well-tested) is dead code in production

Code Location

src/cleveragents/application/services/plan_executor.py — lines 318, 344, 365, 418-422
src/cleveragents/application/services/fix_then_revalidate.py — FixThenRevalidateOrchestrator.run_fix_loop() (complete implementation, never called)

Relationship to #6016

This bug is closely related to #6016 (ValidationPipeline not integrated). Both bugs must be fixed together:

First, wire ValidationPipeline into the execute flow (#6016)
Then, when required validations fail, call run_fix_loop() with appropriate fix and revalidate callbacks

Fix Required

After running the ValidationPipeline and detecting required failures, PlanExecutor should call:

if self._fix_revalidate_orchestrator is not None and summary.required_failed > 0:
    failed_results = [r for r in summary.results if r.mode == ValidationMode.REQUIRED and not r.passed]
    fix_result = self._fix_revalidate_orchestrator.run_fix_loop(
        plan_id=plan_id,
        failed_results=failed_results,
        fix_callback=...,       # actor attempts to fix the issue
        revalidate_callback=..., # re-runs the specific validation
    )
    if not fix_result.final_passed:
        # escalate or fail the plan

## Summary `PlanExecutor` accepts a `fix_revalidate_orchestrator` parameter and stores it as `self._fix_revalidate_orchestrator`, but this orchestrator is **never invoked** anywhere in the execute flow. The fix-then-revalidate loop — which is supposed to automatically fix required validation failures and retry — is completely non-functional. ## What Was Tested - Code-level analysis of `src/cleveragents/application/services/plan_executor.py` - Grep for all usages of `_fix_revalidate_orchestrator` in the file ## Expected Behavior (from spec §Validation Failure Handling) When a required validation fails during Execute: 1.

MoSCoW classification: Must Have

Rationale: This is a Priority/Critical bug — FixThenRevalidateOrchestrator is injected into PlanExecutor but run_fix_loop() is never called. This means the fix-then-revalidate orchestration (a core part of the plan execution pipeline) is completely non-functional. The spec requires validation-gated apply with fix loops. This directly blocks v3.5.0 acceptance criteria.
