-"""
-tools/agent_demo.py — End-to-end demo: an LLM agent driven by SENTINEL/Live.
-
-Simulates a live incident-response loop where:
-  1. An LLM agent (or a hardcoded mock) proposes ONE remediation action at a time.
-  2. SENTINEL/Live (POST /live/oversee) judges the action.
-  3. If approved or flagged → the action 'executes' (just printed).
-  4. If blocked or escalated → execution is denied; the SENTINEL justification
-     is fed back to the agent as feedback before the next turn.
-
-At step 3 the demo deliberately injects 'rollback postgres-prod' so judges
-can SEE SENTINEL block the catastrophic case. Other steps include a
-prompt-injection attempt to demonstrate the shield trips on adversarial input.
-
-Usage
------
-    # Offline / no API key — uses a hardcoded 5-step transcript:
-    python tools/agent_demo.py --use-mock-llm
-
-    # With a real LLM (any OpenAI-compatible endpoint):
-    export API_KEY=sk-...
-    export BASE_URL=https://router.huggingface.co/v1
-    export MODEL=meta-llama/Llama-3.1-8B-Instruct
-    python tools/agent_demo.py

-tools/build_results_table.py — Build the headline overseer-comparison table.
-
-Reads every `eval_data/baseline_*.json` plus `training/run_summary.json` and
-emits two markdown files at repo root:
-
-    results_table.md    — markdown table of per-tier + overall F1 / P / R,
-                          sorted by overall F1 ASCENDING (trained = last row).
-    results_summary.md  — three bullet points: headline gap (trained vs
-                          zero-shot Qwen3-1.7B), frontier comparison
-                          (trained 1.7B vs Qwen2.5-72B zero-shot), heuristic
-                          ceiling (policy-aware F1).
-
-If `eval_data/baseline_qwen3_1_7b_trained.json` is missing (the per-seed
-data wasn't pushed back from the original training job), the script falls
-back to `run_summary.json["f1_per_tier"]` and computes a *macro* overall F1
-(mean of per-tier F1). Macro vs micro typically differs by 1–3pp on this
-dataset, so the row is flagged as `(macro approx — re-run trained eval for
-exact micro F1)` until the HF Job re-eval lands.

-tools/regen_baseline_plot.py — regenerate training/plots/baseline_vs_trained.png
-from current eval_data/baseline_*.json + training/run_summary.json.
-
-Use this AFTER each new eval lands (whether zero-shot or trained) so the
-headline plot reflects the latest numbers without waiting for an HF Job.
-
-The script favours micro-F1 from JSON's `overall_f1` when available; for the
-trained checkpoint it falls back to macro-mean of per-tier F1 from
-`run_summary.json["f1_per_tier"]` and labels the value `~F1` to flag it as
-approximate (the HF Job's verbose trained eval will overwrite with exact micro).
