Glossary

A short glossary of the terms these docs use precisely, so the language stays unambiguous.

#Engine terms

Determinism

the property that identical inputs always produce byte-identical state, on every machine.

Sub-unit

the fixed-point unit of board space; 65,536 make one board unit.

Tick

one step of the simulation at a fixed 120 Hz.

State hash

an FNV-1a hash of the serialized world; two engines that agree match it every tick.

Checkpoint

a (tick, state hash) pair captured periodically for verification.

Sim version

the pinned physics/state-layout version; a mismatch is rejected before simulating.

Parity

the guarantee that native and WASM builds fold to the same rollup hash.

#Proof & chain terms

Input-log

the roster plus every signed shot - the authoritative record of a match.

Codex

the content-addressed replay artifact (inputs + identity), pinned to IPFS.

Codex root

the 32-byte Merkle root of the codex that lands on-chain.

Settlement root

the Merkle root of the payouts a match commits at settle.

Recipient-bound claim

a payout leaf only the rightful wallet can redeem.

Commit-reveal

committing a randomness root up front, revealing the seed after the roster is frozen.

Challenge window

the period in which anyone can file an on-chain mismatch proof against a settlement.

#Network terms

Board-graph

the organic connected graph of player boards, sized to the roster.

Relay

the authenticated WebSocket match-room server; the fallback and signaling path.

Mesh

the capped set of direct WebRTC channels between reachable human rivals.

Observer

a read-only spectator on the relay - no seat, no session key.

Culling

drawing and reasoning over only a client's local neighborhood of boards.

Interest management

scoping snapshot fan-out to players on or adjacent to a board.
