Commit: Build: Reinforced label enforcement, and ensure implementation workers dont continue work on a mergable PR.
Branch: main
SHA: 5a9aaa79ed

Background and Context

retry_auto_debug in src/cleveragents/core/retry_service_patterns.py implements a retry loop with optional debug callbacks. When a debug_callback is provided and returns {"fixed": True}, the loop uses continue to immediately proceed to the next attempt — without sleeping. This bypasses the exponential backoff (await asyncio.sleep(min(2**attempt, 60))) that is applied in all other retry paths.

If the debug callback incorrectly reports {"fixed": True} but the underlying issue persists, the loop will retry at maximum speed without any delay, potentially causing resource exhaustion or API rate limiting.

Current Behavior

# In retry_service_patterns.py - retry_auto_debug wrapper:
if isinstance(debug_result, dict) and debug_result.get("fixed"):
    continue   # ← no sleep before next attempt!

# The sleep only happens at the bottom of the loop:
if attempt < max_debug_attempts - 1:
    await asyncio.sleep(min(2**attempt, 60))

When debug_callback returns {"fixed": True}, the continue statement jumps back to the top of the loop, skipping the asyncio.sleep call entirely.

Expected Behavior

Even when the debug callback reports {"fixed": True}, a brief sleep should be applied before the next attempt to prevent rapid retry loops. The sleep duration can be shorter than the full backoff (e.g., a fixed 0.1s or 1s) to allow the fix to take effect:

if isinstance(debug_result, dict) and debug_result.get("fixed"):
    await asyncio.sleep(1.0)  # brief pause to let fix take effect
    continue

Alternatively, the backoff sleep should be moved to the top of the loop (before the attempt) so it applies regardless of the continue path.

Acceptance Criteria

When debug_callback returns {"fixed": True}, a sleep is applied before the next retry attempt
The sleep duration is configurable or follows the existing backoff pattern
BDD test scenario verifies that rapid retry loops do not occur when debug_callback returns {"fixed": True}

Subtasks

Add sleep before continue in the debug_result.get("fixed") branch
Consider making the "fixed" sleep duration configurable
Add BDD test verifying sleep occurs even when debug_callback returns fixed=True
Verify no existing tests break

Definition of Done

The issue is closed when retry_auto_debug applies a sleep before each retry attempt regardless of the debug_callback result, with a passing BDD test, merged to main.

When a `debug_callback` is provided and returns `{"fixed": True}`, the loop uses `continue` to immediately proceed to the next attempt — **without sleeping**. This bypasses the exponential backoff (`await asyncio.sleep(min(2**attempt, 60))`) that is applied in all other retry paths. If the debug callback incorrectly reports `{"fixed": True}` but the underlying issue persists, the loop will retry at maximum speed without any delay, potentially causing resource exhaustion or API rate limiting. ## Current Behavior ```python # In retry_service_patterns.py - retry_auto_debug wrapper: if isinstance(debug_result, dict) and debug_result.get("fixed"): continue # ← no sleep before next attempt! # The sleep only happens at the bottom of the loop: if attempt < max_debug_attempts - 1: await asyncio.sleep(min(2**attempt, 60)) ``` When `debug_callback` returns `{"fixed": True}`, the `continue` statement jumps back to the top of the loop, skipping the `asyncio.sleep` call entirely. ## Expected Behavior Even when the debug callback reports `{"fixed": True}`, a brief sleep should be applied before the next attempt to prevent rapid retry loops.

✅ Verified — Bug: rapid retry loops when debug_callback returns fixed=True could cause resource exhaustion. MoSCoW: Should-have. Priority: Medium — potential performance/stability issue.
