01 / Overview
Protocols for governed information movement.
OCO protocol work defines how sensitive information moves with purpose, authorization, state, evidence, retention, human oversight, and system boundaries intact.
A protocol is the operating agreement between data, software, people, and automation. OCO uses protocol engineering when information must be transferred, acknowledged, protected, audited, or rendered without losing context. Public descriptions explain purpose and boundaries; sensitive implementation details, security controls, and private protocol internals remain controlled.
OCO delivers protocols when information must move with context, authority, state, evidence, privacy, and recovery rules. A protocol is not only a message format; it is an operating agreement that tells software and people how information may travel, change, expire, be acknowledged, or be rejected.
Protocol Delivery Flow
Controlled movement for sensitive information.
02 / Transfer boundary
Transfer boundary
The work starts by defining what information is moving, why it must move, who may initiate it, who may receive it, what systems are involved, and what must stay outside the protocol.
OCO separates private payloads, public metadata, operator context, system context, legal or retention limits, and emergency stop behavior before building the interface.
03 / Payload model
Payload model
OCO defines the message object, required fields, optional fields, metadata, identifiers, timestamps, signatures or approvals where justified, redaction rules, and data that must never be embedded.
The payload is designed so receiving software can parse, validate, display, store, route, or reject the transfer without guessing what the information means.
05 / State and evidence
State and evidence
OCO defines draft, submitted, received, accepted, rejected, expired, revoked, escalated, archived, or other domain-specific states. Evidence records show what happened without exposing unnecessary private content.
State is not decorative. It controls retries, notifications, retention, visibility, reporting, and whether the receiving surface may act on the transfer.
06 / Failure and recovery
Failure and recovery
Protocols need explicit behavior for invalid payloads, missing authority, partial delivery, expired transfers, rejected messages, duplicated messages, unavailable receivers, and compromised or revoked access.
OCO defines fallback, escalation, owner notification, rollback, manual review, and retention behavior so failure does not create uncontrolled communication.
07 / Receiving surface
Receiving surface
The protocol is delivered through APIs, software, messaging surfaces, operating tools, or OS-level contexts that interpret the transfer consistently. The user experience follows the protocol state.
Screens, notifications, confirmations, logs, and reports are built around the same transfer contract.
