"""Phase 6b — generate failure samples (tired/confused) and append to persona_train.jsonl.
Borrows CANONICAL_SYSTEM_PROMPT, failure prompts, and validation from gen_data.py.
Runs independently so we can iterate on failure prompting without touching the
persona generation pipeline.
Usage:
python append_failures.py
Environment:
INFERENCE_ROUTER_URL (default: http://inference.kvmx.ru)
