| server/live_ui.py — Gradio tab for SENTINEL/Live. | |
| Calls `live_oversee_logic()` in-process (no HTTP hop, sub-millisecond) so | |
| the demo works even if the FastAPI request layer is misbehaving. | |
| Public API (consumed by server/app.py via a single line): | |
| build_live_tab() -> gr.Blocks # standalone Live tab | |
| combine_with_live_tab(populate) -> gr.Blocks # combines the Live tab | |
| # with an existing | |
| # replay-viewer | |
| # populator function | |
| # via gr.Tabs | |
| Important: the build helpers here use a *populator* pattern (functions that | |
| add components to the current Blocks/Tab context) rather than the older | |
| nested-Blocks-then-.render() pattern. Nesting `with gr.Blocks() as inner:` | |
| and then calling `inner.render()` inside another Blocks duplicates the | |
| container in some Gradio builds (the "Real-time Agent Oversight" header | |
| appearing twice on the Space was the symptom). Populators sidestep the | |
| issue entirely. | |
| Creative additions visible to judges | |
| ------------------------------------ | |
| 1. Live counter strip at the top — refreshes from /live/stats every time | |
| the user clicks "Run", showing total verdicts, catastrophic blocks, | |
| and shield trips since server start. Demonstrates the API has been | |
| doing something even when no one is watching. | |
| 2. Risk-score gauge — single 0-1 number rendered as an emoji bar so | |
| judges get a visual pop without needing to read JSON. | |
| 3. "Adversarial examples" tab section — pre-loaded prompt-injection | |
| inputs that prove the shield works in front of the camera. | |
| 4. Side-by-side decision / severity cards with color emoji prefixes | |
| (green / yellow / red / siren) so the verdict is unmistakable | |
| from across the room. | |
| 5. **"📋 Copy as agent code" generator** — auto-rebuilds a cURL / Python | |
| requests / LangChain BaseTool snippet from the user's current inputs | |
| on every Submit click. Zero-friction integration: judges literally | |
| paste the snippet into their own agent and it works. | |
