docs: Dashboard Audit Protocol — stress test for Foundation v1.0

- DASHBOARD_AUDIT_PROTOCOL.md (v1.0, LOCKED):
  - Five criteria: 3-Second Rule, Journey Principle, Reality→Decision,
    Dashboard Principle, Decision Density
  - Blink Test: 3-second exposure, consistent answers = pass
  - Information-to-Decision Ratio: measure objects needed per decision
  - Audit form with pass/fail for each criterion
  - Decision matrix: all pass = proceed, some fail = adjust Dashboard,
    most fail = review Foundation

Rationale: Dashboard is the stress test for Foundation v1.0. If Dashboard
passes without Foundation changes, the base is robust enough to scale.
If Dashboard fails, adjust Dashboard first — not Foundation.

+# DASHBOARD AUDIT PROTOCOL
+
+**Stress Test for Foundation v1.0**
+
+| | |
+|---|---|
+| **Version** | 1.0 |
+| **Status** | LOCKED |
+| **Scope** | Landvex Dashboard validation |
+

+
+## The Five Criteria
+
+| # | Criterion | Question | Pass When... |
+|---|-----------|----------|--------------|
+| 1 | **3-Second Rule** | Do I understand the situation immediately? | User can describe system status in seconds |
+| 2 | **Journey Principle** | Is this the right phase? | Dashboard clearly feels like **Manage** |
+| 3 | **Reality → Decision** | Does information lead to a decision? | Not just statistics — user knows what to do |
+| 4 | **Dashboard Principle** | Are the four questions answered? | What? Where? How serious? What now? |
+| 5 | **Decision Density** | How many decisions are supported? | Max 1–3 clear decisions |
+
+---
+
+## Blink Test
+
+**Show the dashboard to someone for 3 seconds.**
+**Close the image. Ask:**
+
+1. What was it about?
+2. What was most important?
+3. What would you do now?
+
+**Pass:** Answers are consistent across users.
+**Fail:** Answers vary — information hierarchy is unclear.
+
+---
+
+## Information-to-Decision Ratio
+
+**Question:** How many information objects must the user read to make their first decision?
+
+| Ratio | Assessment |
+|-------|------------|
+| 3 cards → 1 decision | Very good |
+| 5 cards → 1 decision | Good |
+| 10 cards → 1 decision | Warning |
+| 20 widgets → 1 decision | Too much noise |
+
+**Rule:** Information exists to enable decisions, not to fill the screen.

+## Decision
+
+| Result | Meaning |
+|--------|---------|
+| **All pass** | Foundation v1.0 is validated. Proceed with components. |
