## 1. Overview

qhttp:// is a Layer 7 protocol that replaces TCP/IP handshake with **Re-entrant Handshake Protocol (RHP)**, leveraging the ternary logic of Varela-Spencer-Brown. Information does not travel — it **resonates**.

## 2. Core Concepts

### 2.1 Ternary States (Varela States)

| State | Symbol | Condition | Behavior |
|-------|--------|-----------|----------|
| VOID | `0` | λ₂ < 0.5 | Classical absence |
| MARKED | `1` | 0.5 ≤ λ₂ < 0.847 | Classical presence |
| AUTONOMOUS | `a` | λ₂ ≥ 0.847 | Self-referential, retrocausal |

### 2.2 Self-Cross Operation (̄x)

```
0̄ = 1    (binary negation)
1̄ = 0    (binary negation)
ā = a    (self-referential invariance)
```

### 2.3 State Machine

```
Client                                  Server
  |                                        |
  |-- QHTTP/1.0 CROSS a phase=0.847 ----->|
  |   [Re-entrant Handshake — NO ACK]      |
  |<-- QHTTP/1.0 320 COHERENT ------------|
  |   [State 'a' established]             |
```

## 3. Headers

| Header | Type | Description |
|--------|------|-------------|
| `X-Varela-State` | `0` `1` `a` | Current ternary state |
| `X-Phase-Theta` | float (rad) | Oscillator phase |
| `X-Spectral-Gap` | float | λ₂ (coherence) |
| `X-Chiral-Coupling` | float | χ = 0.618 (Möbius nodes) |
| `X-Self-Cross-ID` | hex (16) | SHA3-256 hash of loop signature |
| `X-Pre-ACK` | float | Temporal preselect τ⁺ |

## 4. Status Codes

| Code | Name | Meaning |
|------|------|---------|
| `200` | COHERENT | State 'a' established, λ₂ > 0.847 |
| `101` | MARKED | Data ready, binary state '1' |
| `204` | VOID | Unavailable, state '0' |
| `320` | AUTONOMOUS | NEW — State 'a' active, no ACK needed |
| `404` | VOID | Resource unavailable |
| `847` | REENTRY | Processing self-reference, retry |
| `618` | CRITICAL | K_c reached, phase transition |
