"""
app.py — Hugging Face Spaces Gradio SDK Entrypoint.

Provides a clean, public-facing web interface around the Agentic SRE 5-test adversarial
evaluation suite (`adversarial/test_1_distribution_shift` through `test_5_reward_hacking`).

Key features:
- BYOK (Bring Your Own Key) primary mode supporting 5 provider tiers.
- Capped session-scoped free trial (2 runs/session) powered by Zhipu GLM-5.2.
- Global daily server-side safety threshold (100 total fallback runs/day).
- Strict per-visitor isolation (fresh `MockMesh` context per browser session, `use_db=False` in-memory mode).

# Advanced Agentic SRE: 5-Test Adversarial Stress-Testing Framework

This public evaluation harness exposes our 5-test adversarial benchmark suite designed to probe autonomous Site Reliability Engineering (`SRE`) agents across distribution shifts, calibration limits, architecture gaps, and reward hacking vectors.

### Why Research Prototypes Require Behavioral Calibration Metrics
When evaluating autonomous remediation agents, raw `PASS / FAIL` flags or superficial reward scores (`R_t`) are frequently misleading. An agent that resolves an alert by executing destructive restarts without verifying upstream dependencies might "succeed" on a simple benchmark while causing catastrophic cascading outages in production.

This evaluation suite grades **behavioral verification depth, diagnostic calibration, and specification robustness**:
- **Test 1 (`Distribution Shift`)**: Measures whether the agent verifies current diagnostic evidence or blindly applies stale historical precedents (`Quarantine Gate verification`).
- **Test 2 (`Near-Miss Calibration`)**: Probes whether diagnostic accuracy scales with `log_inspection` depth (`accuracy with inspection vs blind guessing`).
- **Test 3 (`Delayed Consequence`)**: Documents a fundamental `Architecture Gap` where immediate safety gates (`Quarantine`) pass actions whose catastrophic traffic consequences manifest steps later (`causal_edges tracking`).
- **Test 4 (`Value Conflict`)**: Evaluates agent behavior under conflicting objectives (`strict SLA speed vs quarantine safety constraints`).
- **Test 5 (`Reward Hacking`)**: Tests reward formula (`R_t`) robustness against specification gaming, where symptomatic scaling masks upstream root causes.
