### Minute 0:00 – 1:00: The Tuesday Morning Crisis (Problem Core Engine)
- **Speaker Action**: Address the jury with Wi-Fi visually disabled.
- **Narrative**:
  > *"Every placement season, university placement cells face a nightmare: 600 students, 12 concurrent companies, 8 interview rooms, and a barrage of last-minute email updates. A student eligible for TechCorp at 7.0 CGPA receives an offer at 10 AM, becoming instantly policy-blocked for an afternoon drive. Two companies demand the same seminar hall at 11 AM. One coordinator uses an outdated spreadsheet, and a candidate with a cleared backlog is wrongfully barred.*
  >
  > *Today, we present the **Institutional Placement Engine**: a 100% offline, mathematically verified platform running on a single laptop that eliminates eligibility disputes, automates policy enforcement, and schedules hundreds of students across dozens of companies in under two seconds."*

### Minute 1:00 – 2:15: Zero-Touch Requirement Extraction
- **Speaker Action**:
  1. Log into the Officer Workspace as `officer` / `officer123`.
  2. Click **Extract Drive** (`/create_drive`).
  3. Paste a messy recruitment circular or select sample circular text.
  4. Click **Extract Requirements**.
- **Demonstration Highlights**:
  - Show the side-by-side verification pane: raw announcement on the left, structured criteria on the right.
  - Point out that CGPA (`7.5`), branch list (`CSE, IT`), active arrears (`0`), and package (`14.0 LPA`) were extracted deterministically in 15 milliseconds without an internet connection or LLM hallucination.
  - Point out the exact source sentence cited for every field.
  - Click **Create Drive & Ruleset**.

### Minute 2:15 – 3:30: Pure-Domain Eligibility & Edge Cases
- **Speaker Action**:
  1. Navigate to **Policy Simulator** (`/policy_simulator`).
  2. Select Candidate `PIPE_002` (Priya Nair).
  3. Select Drive `InnoTech Labs (14.0 LPA)`.
  4. Click **Run Simulation**.
- **Demonstration Highlights**:
  - Point to the live breakdown:
    - **Diploma Substitution**: The candidate lacks a 12th percentage, but her 82.5% Polytechnic Diploma is automatically substituted by the AST evaluator.
    - **Backlog Temporal Horizon**: Her backlog in Engineering Mathematics was cleared on October 15th, *before* today's drive, so it counts as 0 active arrears.
    - **Dream Upgrade Approval**: Although she holds a 6.0 LPA offer from Wipro, InnoTech offers 14.0 LPA (above the 10.0 LPA Dream threshold), approving her upgrade under Policy Clause 2.1.
  - Toggle the Dream Threshold in the sandbox from `10.0` to `15.0 LPA` and re-run: the verdict instantly flips to **Policy Blocked (Clause 2.2)** in 18 ms!

### Minute 3:30 – 4:30: 1-Second Clash-Free Scheduling & What-If
- **Speaker Action**:

  - Emphasize that what-if runs purely in memory with zero database side-effects until official publication.
