| AgentDisruptBench — Disruption Profiles |
| ======================================== |
| |
| File: profiles.py |
| Purpose: Built-in disruption profiles (9 profiles) and a YAML loader for |
| custom profiles. Profiles map a name to an ordered list of |
| DisruptionConfig entries that the engine evaluates per tool call. |

| Key Definitions: |
| BUILTIN_PROFILES : dict[str, list[DisruptionConfig]] All 9 built-in |
| profiles defined in the AgentDisruptBench spec. |
| load_profiles : Load profiles from a YAML file on disk. |
| get_profile : Retrieve a profile by name (built-in or custom). |

| Convention: |
| Every source file MUST include a header block like this one. |
