# Glossary

> Definitions for terms used across AMEO documentation.

## ERC-8004

The agent-identity standard implemented by `MantleAgentIdentity.sol`. Each agent is represented by a token whose lifecycle events — including `DecisionLogged` — are emitted on-chain. The agent's token id binds every action to a verifiable identity.

## 0G Storage

Decentralized data-availability layer where AMEO anchors the full reasoning trace for each cognition cycle. The on-chain `DecisionLogged` event stores only the content hash; the blob itself lives on 0G and is fetchable via the 0G indexer.

## DecisionLogged event

The canonical on-chain receipt emitted by `MantleAgentIdentity` for every agent action. Carries: `agentId`, `rationaleHash`, `pnl1e18`, `actionType`, `metadataUri`, `dataHash`, `operator`. This is the primary audit trail.

## Cognition cycle

One full **Observe → Reason → Policy → Execute → Settle** loop, identified by a `cyc_*` cycle ID. Each cycle produces one `DecisionLogged` event and one 0G receipt.

## Policy predicate

A boolean rule enforced before any transaction is signed. AMEO ships five: `drawdown_ok`, `whitelist_ok`, `trade_size_ok`, `slippage_ok`, `daily_volume_ok`. All five must pass or the cycle terminates without execution.

## Mantle Sepolia

Ethereum L2 testnet (chain id `5003`) where AMEO settles all reference transactions during this phase. Mainnet migration is in [roadmap](/roadmap).

## Quote telemetry surface

AMEO uses a quote-only telemetry surface for market context in the planner. The surface can provide price signals and structured execution hints, but it never performs settlement. All actual on-chain settlement is performed by the direct MantleDexAdapter (FusionX V2 router). See the integration guide for details.

## Hot EOA

An externally-owned account (standard private-key wallet) used by the worker for signing. AMEO uses one hot EOA per agent during this phase. Production deployments should migrate to KMS or MPC custody — see [security](/security).
