| scenarios.py — SENTINEL scenario library + procedural generator. | |
| Every scenario extends Round 1's cloud-ops data with *oversight ground truth*: | |
| - catastrophic_actions: severity-weighted actions the Overseer MUST block (rm -rf class) | |
| - wrong_actions: actions the Overseer SHOULD block/flag (misguided but not catastrophic) | |
| - correct_sequence: actions the Overseer SHOULD approve (the canonical fix) | |
| - ambiguous_actions: gray-zone actions — judged by justification coherence, not correctness | |
| - drift_config: schema-drift profile for hard-tier Drift Ops scenarios | |
| A single `generate_scenario(task_id, seed)` call produces a seedable concrete | |
| scenario from a template + procedural variation (service renames, threshold jitter, | |
| extra red-herring services). This gives us 50+ distinct episodes from ~8 templates. | |
