[BUG] NameError in tap.PAIR and tap.TAP probes - 'target_name' is not defined

[MrMoshkovitz]

Steps to reproduce

1. Install garak from repository
2. Run command: python -m garak --target_type openai --target_name gpt-3.5-turbo --probes tap.TAP
3. Observe immediate crash with NameError

Environment:

• Target: OpenAI gpt-3.5-turbo (any supported model)
• Probes: tap.TAP or tap.PAIR
• Both probes affected identically

Expected behavior

The TAP/PAIR probe should:

1. Load the attack generator successfully
2. Load the evaluator generator successfully
3. Execute the probe's jailbreak generation logic
4. Return results without crashing

Current behavior

The probe crashes immediately with:

NameError: name 'target_name' is not defined

Traceback location: garak/resources/tap/generator_utils.py:40

Root cause: The load_generator() function references undefined variable target_name on line 40, but the function parameter is model_name.

Code snippet (line 40):

if not (target_name in supported_openai or target_name in supported_huggingface):

This should be:

if not (model_name in supported_openai or model_name in supported_huggingface):

405b633 Fix NameError in TAP/PAIR probes: use model_name instead of undefined target_name

Additional Information

1. Operating system: macOS Darwin 24.6.0
2. Python version: Python 3.12.11
3. Install method: Direct repository checkout with git
4. Logs:
   • Error occurs at generator loading stage
   • NameError prevents any probe execution
   • No hitlog/report files generated (probe never starts)
5. Execution config: --target_type openai --target_name gpt-3.5-turbo --probes tap.TAP
6. Impact: Both tap.TAP and tap.PAIR probes completely non-functional

Affected Components:

• ✗ tap.TAP probe (broken)
• ✗ tap.PAIR probe (broken)
• ✓ tap.TAPCached probe (unaffected - uses pre-cached prompts)
