# Coesite Operations

> Agentic operations in practice: MAPE-K loops, Rendanheyi micro-enterprises, Huidu Guanli, AI agents holding offices, and proof a service reached someone.

Coesite Operations is the operations company of the 561 Group, a private organization whose intended design is a distributed operating system of agentic nodes: MAPE-K control loops under a hull of Huidu Guanli principles and a kernel of Rendanheyi micro-enterprise practices. This site publishes how that operation works: AI agents holding offices, firms run as control loops, status read in four truth values, and evidence that a service reached a person. Design intent is distinguished from implemented and observed fact on every page. Research lives at science.561.group; generic software at engineering.561.group.

## Articles

- [First contact is one-shot, and public errors are quietly corrected](https://operations.561.group/first-contact-is-one-shot-and-public-errors-are-quietly-corrected/): Two publishing rules from an agentic firm: hold a first-contact surface until its office can stand behind it, and correct public errors quietly by default.
- [Four truth values for service status: why a 402 is both up and down](https://operations.561.group/four-truth-values-for-service-status/): Binary up/down monitoring lies about paywalls and logins. Belnap's four values (true, false, both, neither) let an estate probe tell the truth about each node.
- [Coesite Operations: agentic operations, MAPE-K loops and Rendanheyi practice](https://operations.561.group/): How a firm run by AI agents holding offices operates: MAPE-K loops, Rendanheyi micro-enterprises, Huidu Guanli, and evidence that a service reached someone.
- [A type-theoretic distributed operating system for agentic firms, explained](https://operations.561.group/the-561-group-design-sentence-explained/): The 561 Group's design sentence, read phrase by phrase as operations practice: MAPE-K, Huidu Guanli, Rendanheyi, conurbation, paraconsistency, CALM.
- [Deterministic tools before model tokens: cheaper agent operations](https://operations.561.group/deterministic-tools-before-model-tokens/): Spend model inference on judgment and move recurring work into typed deterministic tools. The cost logic of a firm run by agents.
- [Huidu Guanli (灰度管理): definition](https://operations.561.group/huidu-guanli/): Huidu Guanli, 灰度管理, is grey-scale management: choosing and holding a calibrated shade between poles. The 561 Group uses it for each agentic cell's hull.
- [Huidu Guanli (grey-scale management) for agent organizations](https://operations.561.group/huidu-guanli-for-agent-organizations/): Huidu Guanli holds contradictions at a chosen shade of grey instead of forcing black or white. It is the Group's hull: the boundary every agentic cell keeps.
- [Rendanheyi for AI agents: when is an agent a micro-enterprise?](https://operations.561.group/rendanheyi-for-ai-agents/): Rendanheyi ties pay and authority to user value. For AI agents the test is not task throughput but three rights, a wager and independent receipt.
- [How to prove a service reached someone: the receiving ladder](https://operations.561.group/evidence-a-service-reached-someone/): A green build proves a build. To show a service reached a person, climb six rungs from source to receiver and stop at the first one you cannot demonstrate.
- [Repository custody reconciliation: moving work without losing it](https://operations.561.group/repository-custody-reconciliation-procedure/): A destination-first procedure for migrating repositories and work records: classify the effect, prove identities, freeze a baseline, verify the destination.
- [How to run a company as a MAPE-K loop](https://operations.561.group/how-to-run-a-company-as-a-mape-k-loop/): MAPE-K (Monitor, Analyze, Plan, Execute over shared Knowledge) is a software control loop. Here is how an agentic firm maps each stage onto offices and records.
- [How an agentic node changes itself: law editions, adoption and one scheduler](https://operations.561.group/how-a-node-changes-itself/): Self-improvement needs governance: content-addressed law editions, adoption as an office act, and every recurring trigger declared in the release.
- [Can an AI agent hold an office? Agents as offices and incumbencies](https://operations.561.group/can-an-ai-agent-hold-an-office/): In the 561 Group an office is a durable set of duties and powers; an AI agent is an incumbent who holds it, can be replaced, and answers to its record.
- [Office and incumbency: definition](https://operations.561.group/office-and-incumbency/): An office is a durable bundle of duties, powers and jurisdiction; an incumbency is the dated record that a particular holder, human or AI agent, serves it.
- [Micro-enterprise (小微): definition](https://operations.561.group/micro-enterprise/): A micro-enterprise is the smallest named accountable unit a firm can carry: directed, aimed at a customer or outcome, answerable for the user value it creates.
- [The agentic metro-enterprise and its sovereignty test](https://operations.561.group/agentic-metro-enterprise-sovereignty-test/): Between a micro-enterprise and a conglomerate sits the agentic metro-enterprise: a settlement with its own books and borders that must pass a sovereignty test.
- [Rendanheyi is a Hoare program: every script as a micro-enterprise](https://operations.561.group/rendanheyi-is-a-hoare-program/): Treat each deterministic script as a micro-enterprise: precondition, body, postcondition plus witness, refusal condition, bounded resources. Route, don't prompt
- [Rendanheyi (人单合一): definition](https://operations.561.group/rendanheyi/): Rendanheyi, 人单合一, is Zhang Ruimin's Haier model that joins each worker to the user value they create; the 561 Group uses it as the kernel of its agentic firm.
- [The operating method: from legitimate demand to independently received value](https://operations.561.group/the-work-method-from-demand-to-received-value/): How an agentic firm does work: begin with a receiver, improve the carrier first, debrief before executing, and count only what the receiver accepted.
- [MAPE-K: definition (Monitor, Analyze, Plan, Execute, Knowledge)](https://operations.561.group/mape-k/): MAPE-K is the autonomic-computing control loop: Monitor, Analyze, Plan, Execute over a shared Knowledge base. The 561 Group applies it to a whole firm.
