The entry point. Not a search bar, but a live monitor of **Epistemic Divergence**.

## 2. The Molecule View (The "Conflict Engine")

User clicks "Semaglutide". This is the core view. It splits reality into three layers.

  [ LAYER 1: THE OFFICIAL TRUTH (Tier 0-1) ]
  ────────────────────────────────────────────────────────────────────────
  FDA Label (2023-01):  "GI adverse events common. No mention of paralysis."
  NEJM Trial (Step 1):  "Nausea (44%), Vomiting (24%). Transient."
  EMA Filing:           "Thyroid signal monitored. No GI alarm."

  [ LAYER 2: THE LATENT SIGNAL (Tier 4-5) ]
  ────────────────────────────────────────────────────────────────────────
  Reddit (/r/Ozempic):  "Stomach paralysis" (Cluster: 412 posts, +45% WoW)
  Twitter (MDs):        "Seeing ER admits for aspiration pneumonia." (12 sigs)
  FAERS (Raw):          "Gastric obstruction" (84 unverified reports)
  ────────────────────────────────────────────────────────────────────────

  [ ANALYSIS: THE SKEPTIC LENS ]
  "The Official Truth says GI issues are 'Transient'.
   The Latent Signal says GI issues are 'Permanent/Severe' (Paralysis).
   
   This is a CATEGORICAL CONFLICT.
   Signal Authority: Low (Tier 5) but Density is High (Vol > 400)."

## 3. The Timeline (The "Time Travel")

User investigates *when* this divergence started.

## 4. The Source Inspector (The "Evidence")

User clicks on the "Reddit Cluster" to see the raw data.

```text

└─────────────────────────────────────────────────────────────────────────────────┘

  SOURCE CLASS: Tier 5 (Anecdotal/Unverified)
  VOLUME:       412 Assertions
  SENTIMENT:    Negative (-0.9)
  
  [ KEY EXCERPTS ]
  1. "ER Doc said my stomach essentially stopped working. Been off Oz for 3mo."
     (Source: Reddit, Karma: 4k, Date: 2 days ago)
     
  2. "Diagnosed with gastroparesis after 6 months on 1mg."
     (Source: PatientsLikeMe, Verified User, Date: 1 week ago)

  [ RELATED CLINICAL CONTEXT ]
  * Does this match Mechanism of Action? YES (GLP-1 slows gastric emptying).
  * Is it in the Label? NO (Label says "nausea", not "paralysis").
```

## 5. The Command Line (The "Power User")

For the analyst who wants to query the graph directly.

```text
> latent query --subject "Semaglutide" --predicate "side_effect" --lens skeptic

[RESULT]
Subject: Semaglutide
Predicate: side_effect

1. Nausea (Confidence: 0.99) [Consensus]
   - Sources: FDA, EMA, NEJM, Reddit

2. Vomiting (Confidence: 0.98) [Consensus]
   - Sources: FDA, EMA, Reddit

3. Gastroparesis (Confidence: 0.45) [CONFLICT]
   - Sources: Reddit (High Vol), Twitter (Med Vol)
   - Contradicted By: NEJM ("No signal")
   - Source Tier Spread: 4 (Tier 1 vs Tier 5)

> latent simulate --event "FDA Warning Added"

[SIMULATION]
If FDA adds "Gastroparesis" warning (Tier 0):
- Conflict Score drops to 0.1 (Resolution reached).
- Liability risk for past prescriptions increases (Knowledge date: 2023-Q2).
```
