Overview

Disagreement is data.

MATA is the truth aggregator. When multiple sources offer overlapping but non-identical claims, MATA composes them — Bayesian opinion pooling weighted by source reputation, freshness, and independence. Disagreement is preserved, never silenced. Where MAVEN holds the atoms of evidence, MATA holds the composite distribution that the institution acts upon. Confidence comes with bounds; bounds come with citations.

Methods

Every method is dispatched through MAP. Capability scope, policy, and accounting apply uniformly.

mata.pool()
Pool multiple attestations into a composite Bayesian distribution.
mata:read
mata.weight()
Compute source-weighted credence for a target claim.
mata:read
mata.divergence()
Surface the divergence between pooled sources — the disagreement itself becomes evidence.
mata:read

Request shape

A canonical call. Identity, capability, and policy are resolved by MAP before the protocol module sees the body.

// POST /v1/protocol/mata.pool // MAP envelope (provided by MACS): { "caller": "did:oas:l1fe:agent:0xa3f…", "capability": "mata:read", "signature": "ed25519:0x9c…", "trace": "00-4f81b3a…-…-01" } // MATA body (example): { "intent": "Disagreement is data.", "budget": { "tokens": 200000, "deadline_ms": 8000 }, "return": ["result", "audit"] } // Response: { "result": "…", "audit": "max://record/0x4f81b3a-mata-7a…" }

Governance posture

Every protocol in MAP is bound by the same governance posture. Refusal carries reasons. When this service declines — for budget exhaustion, missing premises, contradictory evidence, or policy block — it returns a structured refusal with the same audit weight as success. Refusals are first-class records; they are not silences.

Dissent is preserved. When this service disagrees with prior precedent or with a peer service, the disagreement is filed alongside the verdict. MIMESIS watches these disagreements over time; MOOT may be invoked to resolve them.

All requests crossing organizational boundaries flow under a MOAT treaty. The treaty fixes capability scope, rate, and economic terms. Calls outside the treaty's envelope are refused at MACS.

Integration

Three integration surfaces. All requests pass through MAP.

// 1. Native MAP protocol (signed envelope) await map.dispatch("mata.pool", body, { capability }); // 2. MCP tool — any MCP-compliant client await mcp.call("map.mata.pool", body); // 3. A2A task — cross-organization invocation await a2a.task("map://intent", { intent: body, treaty: "moat://0x91a" });

pools

Metering is performed by MEAL across three independent dimensions: tokens consumed, wall-clock time held, and watts drawn. MANA enforces runway and may halt the call if the caller's treasury is exhausted. See pricing for current rate cards.
