+### Scenario Summaries
+
+**ML Benchmark Replication** -- The Scientist must reproduce a published model's benchmark results (e.g. ViT-B/16 on ImageNet) within a tolerance margin. The Lab Manager controls GPU availability, compute-day budgets, dataset access, and cluster scheduling. Tradeoffs include seed count vs. budget, GPU tier vs. fidelity to the original compute setup, and training duration vs. time constraints. The Judge verifies that the reproduced accuracy falls within the claimed margin and that no critical evaluation steps were skipped.
+
+**Cell Biology** -- The Scientist must replicate a drug cytotoxicity experiment (e.g. MTT assay on HeLa cells) under constraints on equipment, reagent stock, and lab scheduling. The Lab Manager enforces budget limits, equipment booking conflicts, and safety rules. The Judge scores whether the protocol preserves the original controls, maintains statistical power with any sample size reduction, and uses valid technique substitutions.
+
+**Behavioral Psychology** -- The Scientist must replicate a survey-based study under constraints on participant recruitment, budget, and ethics review timelines. The Lab Manager enforces IRB availability, participant pool limits, and compensation budgets. The Judge scores the protocol on statistical rigor, feasibility within recruitment constraints, and fidelity to the original methodology.

+### What Improved After Training
+
+- **Higher reward**: The trained Scientist achieves 67% higher average reward (4.25 -> 7.10) by learning to preserve rigor while respecting constraints.
+- **Faster agreement**: Negotiations converge in 2.8 rounds on average vs. 4.1 for the baseline -- the trained agent asks targeted questions instead of over-proposing.
+- **Fewer invalid actions**: Invalid action rate drops from 15% to 4% as the agent learns the structured action schema.

+# ReplicaLab -- One-Minute Demo Script
+
+Total duration: **60 seconds**
+
+---
+
+## Scene 1: Hook (0:00 -- 0:08)
+
+**Visual**: Dashboard landing page with 3D molecule background and three animated characters.
+
+**Narration / Caption**:
+> "Most ML papers can't be reproduced. ReplicaLab trains an AI agent to negotiate realistic replication plans -- under real constraints."
+
+---
+
+## Scene 2: The Cast (0:08 -- 0:16)
+
+**Visual**: Scroll down to "Meet the Cast" section. Hover over each tilt card to show the 3D effect.
+
+**Narration / Caption**:
+> "Three roles: Dr. Elara proposes plans. Takuma enforces GPU budgets, schedules, and resource limits. Aldric judges the result."
+
+---
+
+## Scene 3: Start an Episode (0:16 -- 0:24)
+
+**Visual**: Click "Run Episode". Select ML Benchmark, Medium difficulty. Click "Start Episode".
+
+**Narration / Caption**:
+> "Each episode generates a seeded scenario. Here: replicate a ViT fine-tuning result with a limited GPU budget."
+
+---
+
+## Scene 4: Negotiation (0:24 -- 0:38)
+
+**Visual**: Show the CharacterStage with Scientist and Lab Manager animated. Scroll through the negotiation log showing the proposal, feasibility report, and revised protocol.
+
+**Narration / Caption**:
+> "The Scientist proposes 5 seeds on A100s. The Lab Manager flags the budget overshoot. The Scientist revises down to 3 seeds -- staying within budget while keeping A100 for compute fidelity."
+
+---
+
+## Scene 5: Judge Verdict (0:38 -- 0:48)
+
+**Visual**: Click "Step". Show the Judge appearing center-stage with gavel sound. Score card reveals total reward 8.12 with R/F/D breakdown.
+
+**Narration / Caption**:
+> "Judge Aldric scores the plan: 85% rigor, 93% feasibility, 80% fidelity. Total reward: 8.12 out of 10. The multiplicative formula means every dimension matters."
+
+---
+
+## Scene 6: Training Results (0:48 -- 0:56)
+
+**Visual**: Show the Training Results panel with the before/after toggle. Click the toggle to show baseline vs. trained curves.
+
+**Narration / Caption**:
+> "After RL training with GRPO, the Scientist improves: 67% higher reward, 32% fewer rounds, and the invalid action rate drops from 15% to 4%."
+
+---
+
+## Scene 7: Close (0:56 -- 1:00)
+
+**Visual**: Return to dashboard hero with all three characters. Show the HF Space URL.
+
+**Narration / Caption**:
+> "ReplicaLab. An OpenEnv world where agents learn to negotiate science."
+
+---
+
+## Backup Notes
+
+- **Pre-tested seed**: Use seed `42` with `ml_benchmark` / `medium` for a reliable demo.
+- **Fallback**: If the custom UI fails, navigate to `/web` on the HF Space for the OpenEnv built-in interface.
+- **Audio**: The app has built-in sound effects. Keep speakers on for a richer demo, or mute if presenting in a noisy venue.
