SUBIT‑64 Protocol

SUBIT‑64 is a compact six‑axis bit protocol for representing semantic states, transitions, and deterministic system behavior.
Each state is a 6‑bit integer from 0 to 63.
Each axis corresponds to a single bit: A, B, C, D, E, F.

The Python SDK provides canonical encoding, decoding, and a deterministic finite‑state machine.

Python SDK

Installation

The SDK has no external dependencies. Import directly from the repository:

from subit64 import encode, decode, FSM

---

Encoding

value = encode({"A": 1, "B": 0, "C": 1, "D": 0, "E": 0, "F": 1})
print(value)  # 37

---

Decoding

axes = decode(37)
print(axes)
# {'A': 1, 'B': 0, 'C': 1, 'D': 0, 'E': 0, 'F': 1}

---

Finite State Machine

The FSM maps a current state and event to a next state.

fsm = FSM({37: {"act": 41}})
next_state = fsm.next(37, "act")
print(next_state)  # 41

If a transition is undefined, the FSM returns the current state.

JSON Schemas

The schemas/ directory contains the official protocol schemas:

• state.schema.json
• event.schema.json
• transition.schema.json

These ensure compatibility across implementations.

Testing

Run the smoke test:

python3 test_sdk.py
