Acephalic Systems

A jellyfish has no brain, heart, or vessels — yet it senses, swims, hunts, and avoids. Acephalic Systems explores moving MARIA OS away from a single Coordinator toward a distributed, self-regulating mesh: federated pacemakers, fail-closed reconciliation, edge perception, and minimal statistic sharing.

Acephalic Systems

A System With No Brain,
No Single Point of Failure

A jellyfish has no brain, heart, or vessels — yet it senses, swims, and avoids. MARIA OS moves the same way: away from one Coordinator, toward distributed self-regulation.脳・心臓・血管を持たないクラゲに学ぶ、中央障害点のない分散アーキテクチャ。

Distributed Nerve Net

分散神経網

Sensing and response live in a mesh of local ganglia. No node is a single point of failure.

Distributed Pacemakers

分散ペースメーカー

Many independent pacemakers keep the loop alive. Rhythm survives even when one stops.

Gastrovascular Distribution

拡散輸送

Resources and evidence diffuse over the shortest path — co-located near where they are used.

Local Perception

ローカル感覚処理

Each rhopalium senses and decides locally. No central world-model is assumed.

SP-7 · Pacemaker Federation

Fail-Closed Federation

Each Agent Runtime evaluates policy and continues its loop on its own. When the network partitions or the Coordinator drops, every runtime keeps running fail-closed. On rejoin, the most restrictive state always wins.通信断・Coordinator障害でもローカルポリシーで継続。再統合は「最も制限的な状態」を優先。

Local AutonomyPartition TolerancePolicy Drift DetectionSafe Resync

Safe Fold Engine

Reconciliation is a commutative, monotone fold — it converges to the most restrictive verdict regardless of merge order.

ALLOW+DENYDENY
OPEN+CLOSEDCLOSED
UNKNOWN+DENYDENY

Fold law fixed by property tests (commutative · monotone · convergent), in the style of law-latency-reflex.

No Global Brain

Sense Locally, Share Little

SP-8 · Mesoglea Evidence Co-location

Evidence next to the decision

証拠を判断点の隣に

Place evidence, permission, and audit metadata beside the decision point. Shorten transport, simplify chain-of-custody, cut context drift.

SP-9 · Brainless Perception

Minimal sufficient statistics

最小十分統計量のみ共有

Each harness observes locally and shares only error rate, latency, violation count, and confidence delta — never a full central world-model.

Human Decision Boundary

Some calls stay human

人間に残す判断

Contracts, legal, finance, governance changes, and privilege escalation always route to a human — fail-closed, never resolved autonomously.
