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-ledger
**Machine bundle:** https://miscsubjects.com/api/articles/oip-system-ledger/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.

LEDGER

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: 4. Machine system map: /api/dispatch?map=LEDGER&format=markdown. Root: /a/oip.

Operations

LEDGER_QUERY

Raw SELECT against the LEDGER D1 binding (loop-shared-events.events table). $1=SQL, rest = bind params. Returns JSON array of result rows Use when: you need to ledger query Arguments: $1. Human article: /a/oip-capability-ledger-query. Machine doc: ?key=LEDGER_QUERY&format=markdown. Invocation history: /api/invocations?object_id=LEDGER_QUERY.

LEDGER

Read your own ledger to troubleshoot: recent messages, each tool you ran with its output/error, and your reply. $1 optional = a trace_id for one message Use when: you need to ledger Arguments: see content. Human article: /a/oip-capability-ledger. Machine doc: ?key=LEDGER&format=markdown. Invocation history: /api/invocations?object_id=LEDGER.

LEDGER_ERRORS

Return the most recent ledger event whose own response starts with ERR. Use when: Cyrus asks for the last error, recent errors, or why something failed. Arguments: none.. Human article: /a/oip-capability-ledger-errors. Machine doc: ?key=LEDGER_ERRORS&format=markdown. Invocation history: /api/invocations?object_id=LEDGER_ERRORS.

LEDGER_EXEC

Run a non-SELECT D1 query against the LEDGER database (loop-shared-events). INSERT/UPDATE/DELETE only. Use when: writing audit events or other data to the shared ledger. Arguments: $1 = SQL. Pipes inside SQL are preserved. Remaining args = bind params.. Human article: /a/oip-capability-ledger-exec. Machine doc: ?key=LEDGER_EXEC&format=markdown. Invocation history: /api/invocations?object_id=LEDGER_EXEC.

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
