Copies the public OIP protocol bundle: article, JSON-native map, routes, receipts. No owner token.

§SELF — protocol specification
## §SELF — OIP protocol specification

**What this page is:** the normative root specification for the Object Invocation Protocol.

**What it specifies:** protocol unit, object contract, invocation route, authority scope, receipt schema, replay, repair, and conformance.

**Read:** https://miscsubjects.com/a/oip-system-sibling
**Machine bundle:** https://miscsubjects.com/api/articles/oip-system-sibling/bundle?format=markdown
**Live object tree:** https://miscsubjects.com/api/dispatch?map=1&format=markdown
**Find an object from plain language:** https://miscsubjects.com/api/dispatch?ask=<what you want>
**Read one object:** https://miscsubjects.com/api/dispatch?key=<KEY>&format=markdown

**Proof rule:** an action is not proven by intent, description, or a 200. It is proven by the ledger and the OIP receipt for the invocation.

Sibling worker

A generated article for one OIP shelf. It lists every operation in this API/CLI/MCP/device/model/core subsystem, links each leaf article, and gives the ledger path for proof.

This page is the operating article for one build subsystem. It is generated from live directory rows. If a task belongs to this subsystem, scan the operations below, open the matching capability article, run only the exact object named there, and verify by receipt.

Kind: core. Capabilities: 5. Machine system map: /api/dispatch?map=SIBLING&format=markdown. Root: /a/oip.

Operations

SIBLING_HEALTH

Liveness check for the sibling Worker (loop-safe-sibling) that hosts cron + Durable Objects + Queues + Workers AI. Returns {ok,name,ts}. No args Use when: "is the sibling worker up" or "ping the sibling" Arguments: see content. Human article: /a/oip-capability-sibling-health. Machine doc: ?key=SIBLING_HEALTH&format=markdown. Invocation history: /api/invocations?object_id=SIBLING_HEALTH.

SIBLING_DO_PING

Ping a named ExpertDO instance on the sibling Worker. Each name gets its own Durable Object id, its own SQLite state. $1=DO name (e.g. CF_EXPERT, STRIPE_EXPERT, default) Use when: "ping the CF expert DO" or "is the <name> expert alive" Arguments: see content. Human article: /a/oip-capability-sibling-do-ping. Machine doc: ?key=SIBLING_DO_PING&format=markdown. Invocation history: /api/invocations?object_id=SIBLING_DO_PING.

SIBLING_DO_CHAT

Chat with a named ExpertDO using Workers AI inside the DO context. $1=DO name. $2=JSON body string with shape {"messages":{"role":"user","content":"..."}],"model":"@cf/meta/llama-3.3-70b-instruct-fp8-fast"}. Uses $$2 raw so the JSON object passes through unescaped Use when: "ask the CF expert about workflows" or "chat with the <name> DO" Arguments: see content. Human article: [/a/oip-capability-sibling-do-chat. Machine doc: ?key=SIBLING_DO_CHAT&format=markdown. Invocation history: /api/invocations?object_id=SIBLING_DO_CHAT.

SIBLING_WORKFLOW_DELIVER_TRIGGER

Trigger a one-off DeliverWorkflow instance on the sibling Worker. Returns {id, status}. $1=optional JSON params (default {}) Use when: "run the durable deliver workflow" or "fire DeliverWorkflow" Arguments: see content. Human article: /a/oip-capability-sibling-workflow-deliver-trigger. Machine doc: ?key=SIBLING_WORKFLOW_DELIVER_TRIGGER&format=markdown. Invocation history: /api/invocations?object_id=SIBLING_WORKFLOW_DELIVER_TRIGGER.

SIBLING_WORKFLOW_DELIVER_STATUS

Status of a DeliverWorkflow instance. $1=instance id (from the trigger response) Use when: "what is workflow <id> doing" Arguments: see content. Human article: /a/oip-capability-sibling-workflow-deliver-status. Machine doc: ?key=SIBLING_WORKFLOW_DELIVER_STATUS&format=markdown. Invocation history: /api/invocations?object_id=SIBLING_WORKFLOW_DELIVER_STATUS.

system
The OIP article layer is generated from live directory rows, so it documents the objects that actually run the reference implementation.
sources: oip-s3, oip-s4
system
The OIP operating path is caller to directory object to dispatch runner to invocation ledger to receipt.
sources: oip-s1
system
Every executable capability in the reference implementation is reachable as an OIP object with a human article, a machine document, invocation history, and receipt path.
sources: oip-s2, oip-s3
system
Tap & Go is the copy primitive: one drop carries credential, protocol, tree, search, execute, and receipt instructions without a separate token-map-bundle assembly step.
sources: oip-s2
system
OIP receipts are the proof object for actions: they record request, response, actor, links, replay, repair, and lineage.
sources: oip-s2, oip-s5
