# Heartbeat Architecture
|
|
|
|
The rhythmic cycle that makes the nimmerverse live.
|
|
|
|
---
|
|
|
|
## Overview
|
|
|
|
Without a heartbeat, everything fires chaotically. With a heartbeat, the system pulses in coordinated cycles. Sense, process, decide, act, verify, reward. Repeat.
|
|
|
|
Two hearts. Different rhythms. One organism.

## Two Hearts

|
|
```

|

|
|
|

|
## The Beat Cycle
|
|
|
|
Each heartbeat triggers a complete cycle:
|
|
|
|
```
|
|
♥ BEAT
|
|
│
|
|
├──→ 1. SENSE
|
|
│ Collect sensor inputs since last beat
|
|
│
|
|
├──→ 2. TRANSLATE
|
|
│ State machines fire → vocabulary tokens
|
|
│
|
|
├──→ 3. PROCESS
|
|
│ Nyx receives vocabulary stream
|
|
│
|
|
├──→ 4. DECIDE
|
|
│ Nyx outputs decision/response
|
|
│
|
|
├──→ 5. ACT
|
|
│ Decision flows to gardens
|
|
│
|
|
├──→ 6. VERIFY
|
|
│ Check predictions against reality
|
|
│
|
|
└──→ 7. REWARD
|
|
Update weights (+V / -V)
|
|
|
|
♥ NEXT BEAT
|
|
```

## Heart Properties
|
|
|
|
| Property | Real Garden Heart | Virtual Garden Heart |
|
|
|----------|-------------------|----------------------|
|
|
| **Speed** | Wall clock (fixed) | Compute clock (variable) |
|
|
| **Cost** | Free (time passes anyway) | Costs V to accelerate |
|
|
| **Rhythm** | 1 beat = 1 second | 1 beat = 1 inference cycle |
|
|
| **Sync** | Always "now" | Runs ahead, must verify back |
|
|
| **Skip** | Cannot skip | Can skip if V depleted |
|
|

## Lifeforce Connection
|
|
|
|
```
|
|
REAL HEART: ♥ . . . . ♥ . . . . ♥
|
|
(beats for free, can't speed up)
|
|
|
|
VIRTUAL HEART: ♥♥♥♥♥♥♥♥♥
|
|
(each beat costs V, can go faster)
|
|
|
|
│
|
|
▼
|
|
|
|
LIFEFORCE POOL: ████████░░░░░░░░
|
|
(virtual thinking depletes)
|
|
|
|
│
|
|
▼
|
|
|
|
VERIFICATION: Real confirms virtual prediction
|
|
→ +V reward → pool refills
|
|
```
|
|
|
|

|
|
|
|
## Synchronization
|
|
|
|
Virtual garden can run ahead, but must sync back to real:
|
|
|
|
```
|
|
REAL: ♥─────────────────♥─────────────────♥
|
|
│ │ │
|
|
VIRTUAL: ♥♥♥♥♥♥──sync──────♥♥♥♥♥──sync──────♥♥♥♥♥
|
|
▲ ▲
|
|
│ │
|
|
checkpoint checkpoint
|
|
(verify predictions against real)
|
|
```
|
|
|
|
**Sync Rules:**
|
|
- Virtual predictions queue until real catches up
|
|
- Verification only happens at real heartbeats
|
|
- Unverified predictions decay in confidence over time
|
|

## Dual Timestamp
|
|
|
|
Every event carries two timestamps:
|
|
|
|
```
|
|
event:
|
|
real_time: 2025-12-04T23:45:00Z (wall clock)
|
|
virtual_time: beat #847291 (cycle count)
|
|
heartbeat_id: uuid (which beat)
|
|
```
|
|
|
|
This allows:
|
|
- "What happened in reality at time T?"
|
|
- "What did she think at beat N?"
|
|
- "How far ahead was virtual when real caught up?"
|
|
|
|

|
|
|
|
## Schema
|
|
|
|
```sql
|
|
heartbeats:
|
|
id (uuid, primary key)
|
|
garden (enum: real | virtual)
|
|
beat_number (bigint, incrementing)
|
|
real_time (timestamp, wall clock)
|
|
duration_ms (int, how long cycle took)
|
|
nodes_fired (int, count)
|
|
v_cost (float, lifeforce spent)
|
|
v_earned (float, from verifications)
|
|
v_balance (float, after this beat)
|
|
```
|
|
|
|

|
|
|
|
## Design Principles
|
|
|
|
1. **Rhythm over chaos**: Everything syncs to heartbeat
|
|
2. **Two clocks**: Real is free and fixed, virtual is fast but costly
|
|
3. **Natural batching**: Process per-beat, not per-event
|
|
4. **Verifiable sync**: Virtual must prove itself against real
|
|
5. **Lifeforce gated**: Can't think infinitely fast
|
|

## Connection to Architecture
|
|
|
|
The heartbeat is:
|
|
- The **rhythm** of the nervous system
|
|
- The **cycle** of sense→process→act
|
|
- The **sync primitive** between gardens
|
|
- The **natural batch boundary** for storage
|
|
- The **unit of experienced time**
|
