# 🗄️ Data Architecture v5

> **ONE JOB:** THE SCHEMA — waves, gates, correlations, verification outcomes.

> *"Cells emit waves. Gates correlate. Phoebe remembers everything."*

## Overview

**Version 5** aligns with the wave/gate model. Decision trails come from **gate transitions**, not nerve executions.

| Layer | Entity | Database Table | What It Captures |
|-------|--------|----------------|------------------|
| **Waves** | Cells | `wave_signals` | WaveSignal emissions from cells |
| **Gates** | Gates | `gates` | Resonant gate state and weight |
| **Correlation** | Gates | `gate_transitions` | When gates OPEN/STABLE/CLOSED |
| **Learning** | Gates | `correlation_events` | What correlated (training data) |
| **Verification** | Real Garden | `verification_outcomes` | Ground truth feedback |
| **Behavior** | Nerves | `nerves` | Behavioral patterns (respond to gates) |
| **Identity** | Organisms | `organisms` | Emergent patterns |

```

**Key insight:** Training data comes from `correlation_events` and `verification_outcomes`, not from "decision trails." The gate transition IS the decision — what correlated, what opened, what was verified.

### Decision Trails → Gate Transitions

**The old `decision_trails` table is replaced by `gate_transitions` and `correlation_events`.**

The key insight: **decisions ARE gate transitions**. When a gate opens, that IS the decision. What correlated to cause it, what tier it routed to, what the verification outcome was — that's all captured in the gate tables above.

```
OLD MODEL:
  nerve executes → decision_trail row created → outcome logged

NEW MODEL:
  cells emit waves → gate accumulates correlation → gate transitions → nerve activates

  Training data comes from:
  - gate_transitions (what opened, what triggered it)
  - correlation_events (what patterns led to opens)
  - verification_outcomes (ground truth feedback)
```

**The learning loop:**

```sql
-- What patterns open gates?
SELECT
    ce.signals_in_window,
    ce.aggregate_correlation,
    ce.result,
    vo.outcome as verification
FROM correlation_events ce
LEFT JOIN verification_outcomes vo
    ON vo.original_signal_id = ce.id
WHERE ce.result = 'opened'
ORDER BY ce.created_at DESC;

-- How is gate weight evolving?
SELECT
    g.gate_name,
    g.weight,
    COUNT(gt.id) as transitions,
    AVG(gt.correlation_score) as avg_correlation
FROM gates g
JOIN gate_transitions gt ON gt.gate_id = g.id
WHERE gt.transitioned_at > NOW() - INTERVAL '24 hours'
GROUP BY g.id
ORDER BY g.weight DESC;
```

## Migration from v4 → v5

### New Tables (Wave/Gate Model)
- `wave_signals` → What cells emit
- `gates` → Resonant gate state and weight

- `verification_outcomes` → Real Garden feedback

### Changed Tables
- `cells` → Now have `domain`, `target_gates`, `total_waves_emitted`
- `nerves` → Now have `trigger_gate` instead of `priority`
- `organisms` → Now have `active_gates` instead of priority-based `active_nerves`

### Removed Tables
- `decision_trails` → **Replaced by `gate_transitions` + `correlation_events`**

### Preserved Tables
- `objects` → Unchanged
- `partnership_to_nimmerverse_messages` → Unchanged
- `nimmerverse_to_partnership_messages` → Unchanged
- `variance_probe_runs` → Unchanged
