Canary LP · Technical Library

How Canary Works — Under the Hood.

Eight documents for engineers evaluating the Canary platform. Architecture, canonical data model, full field registry, detection rules, risk queries, and a Redoc-rendered API. Source of truth, no marketing.

Onboarding

Getting Started

Fifteen minutes from landing here to a working mental model of the platform. Guided tour of the library, per-persona paths.

Diagrams

The Mermaid Atlas

52 architecture diagrams across 8 categories — pipeline, lifecycle, orchestration, infrastructure, protocol. Every subsystem, visualized.

Overview

Architecture

End-to-end walkthrough — ingress, TSP pipeline, detection, investigation, search, metrics, and deployment shape.

Data Model

The CRDM

The Canonical Reference Data Model. Three generations of enterprise LP data architecture, now Square-native.

Metadata

The Field Registry

Every table, every column, every field. The canonical metadata layer that feeds Owl search, UI rendering, and API contracts.

Detection Rules

The Detection Catalog

37 loss-prevention rules across 10 categories and three execution tiers — generated from the source code that runs in production.

Queries

The Risk Dictionary

21 predefined loss-prevention queries wired to deterministic drill paths. Plain-English questions, z-score answers.

API Surface

The elJeffe API

Universal event notarization on Bitcoin L1. Architecture specification for the receipt/inscription layer. Full REST reference lives on the devops surface for agents.
