**Data flow:** Human intention enters at the top. Evidence flows upward from measurements. Proposals exit at the bottom with full provenance. The Persona governs every layer's disposition toward the unknown.

## 3. INTENTION TRANSLATOR

### The Problem
Human instructions are informal, contextual, and ambiguous. AI interpretation fills gaps — sometimes correctly, sometimes not. The gap between "what was said" and "what was understood" is where bugs are born.

### The Design

```javascript
{
  id: "solidivism:requirement:motherboard-floor:v1",
  type: "REQUIREMENT",

  // What was actually said (the epistle, not the interpretation)
  sourceInstruction: {
    text: "The floor should look like a motherboard",
    speaker: "solidivism:person:the-king:v1",
    when: "2026-10-08T21:36:00Z",
    // The raw data. Not paraphrased. Not cleaned up.
  },

  // AI interpretation (explicitly marked as interpretation)
  interpretation: {
    by: "solidivism:agent:solid:v1",
    understood: [
      "Floor texture should resemble a printed circuit board",
      "Red traces on dark background (matching tactical aesthetic)",
      "Tiled seamlessly across the floor plane"
    ],
    // Each understood item tagged:
    confidence: "medium",  // "motherboard" could mean green PCB, not red/black
    ambiguities: [
      "Color scheme not specified — assumed tactical red/black from context",
      "Trace density not specified — chose moderate density",
      "Tile size not specified — chose 512px canvas, 8x8 repeat"
    ],
    // What was assumed vs what was stated
    stated: ["motherboard appearance"],
    assumed: ["red/black color", "trace density", "tile dimensions"],
  },

  // Reviewable requirements (what the human can verify)
  requirements: [
    {
      id: "req-001",
      statement: "Floor renders a circuit-board-like pattern",
      verifiable: "Visual inspection: does it look like a motherboard?",
      verifiedBy: null,  // filled on review
    },
    {
      id: "req-002",
      statement: "Pattern tiles seamlessly (no visible seams)",
      verifiable: "Visual inspection at tile boundaries",
      verifiedBy: null,
    },
    {
      id: "req-003",
      statement: "Color scheme matches tactical aesthetic (red on black)",
      verifiable: "Compare to building textures",
      verifiedBy: null,
      note: "ASSUMED — King did not specify colors. Requires confirmation."
    }
  ],

  // Review status
  reviewStatus: "pending",  // pending | approved | revised | rejected
  reviewedBy: null,
  reviewedWhen: null,
}
```
