# Lightday — One Care Engine. Three People. One Patient Timeline.

Lightday connects three key roles through an intelligent clinical engine:

* **Doctor (Dr. Rao):** Dictates visits, medications, and discharge summaries. The chart writes itself; the physician decides and signs.
* **Nurse (Asha/Meena):** Photographically verifies wristbands, vitals, and consent. Camera tracking counts instruments/swabs, blocking closure until saved.
* **Patient (Vani):** Checks in remotely, matches medicine strips to prescriptions, and accesses medical records instantly.

### Three Roles. Three Meta Models.

| Role | Model | Core Responsibility |
| --- | --- | --- |
| **Watcher** | SAM 3.1 | Counts instruments & swabs (tray to bucket) |
| **Listener** | Muse Voice | Transcribes dictation, orders & medications |
| **Reader** | Muse Spark 1.3 | Audits wristbands, vitals, strips & drafts |

> **Core Rule:** AI never decides; a human confirms.
> Every prediction provides an audit view: raw input, output, usage, and clinician actions.

---

### Impact (30%)

Lightday eliminates retained surgical swabs, cuts medication errors, and replaces paper tracking across clinics.

**Proven Workflows:**

* **15/15/0 Count:** Camera-based swab/instrument count completed and verified.
* **Medication Match:** Home blister strips matched to electronic prescriptions.
* **Safe Discharge:** Unlocked only after all clinical checklist evidence aligns.

Two production modules (**Doctor Dictation** & **Ward Care**) share one patient timeline, one Meta Model API key, and an inspectable audit log.

### Meta AI Tooling (25%)

Meta models serve as active senses, not generic chatbots:

* **SAM 3.1 (Vision):** Audits pre/post-op surgical counts and identifies missing items via frame evidence.
* **Muse Spark 1.3 (Vision & Reasoning):** Verifies wristbands, vitals, and consent (5.9s–9.7s latencies); reads packaging and drafts handovers.
* **Muse Voice (Speech):** Captures operative orders and bedside notes into structured entries requiring confirmation.

*Telemetry logs execution step, latency, and failure states. Rules-only outputs are explicitly marked.*

---

### Technical Depth (20%) & Demo (25%)

Monorepo with unified `.env` (`META_API_KEY`):

* **Doctor Dictation:** `doctor-dictation/` (port 8000)
* **Count Guard:** `count-guard/` (frontend 5173, API 8100)

**Highlights:**

* Flagged count mismatches block surgical closure; invalid photos are rejected with reasons.
* Non-destructive corrections preserve provenance. Tested via `pytest`, `node`, and `make demo-check`.
* 3-minute video built from 18 live-API captures, voiceover, and a MusicGen score. Local switcher dock navigates Doctor, Nurse, and Patient roles seamlessly.

---

*Safer, connected clinical workflows via multimodal AI — keeping every clinical decision in human hands.*
