[WIP] Find code that maintains queue for ancillary effects

[Copilot]

• Explore repository structure and understand the codebase
• Locate code maintaining queue for ancillary effects
• Document findings in code comments
• Create tests to validate the queue mechanism
• Verify functionality with existing tests

Key Finding:

The code that maintains a queue for ancillary effects is located in /home/runner/work/pdkb-planning/pdkb-planning/pdkb/actions.py in the _expand method (lines 98-124).

The queue is named condleft and works as follows:

1. Line 103: Initializes the queue with positive and negative conditional effects
2. Line 108: Iterates while queue has items using condleft.pop(0) (FIFO behavior)
3. Lines 114-122: For each effect, if relevant, adds it to the result set and generates additional effects using compiler functions
4. Line 116 & 122: condleft.extend() adds new effects to the queue for processing

The ancillary effects are generated by compiler modules in /home/runner/work/pdkb-planning/pdkb-planning/pdkb/ancillary/:

• kd45_closure.py - Handles belief closure
• mutual_awareness.py - Handles commonly known effects
• negation_removal.py and uncertain_firing.py - Other effect transformations

Original prompt

find the code that maintains a queue for ancillary effects to be applied
