🔱 Omni — The All-Seeing Eye

Omni Header

The Federation Governance Tricorder — A modular, extensible observation engine that scans, maps, and guards codebases at galactic scale.

"Never trust documentation, trust reality." — ACE

Omni is a Python-powered passive observation platform that discovers the truth about your code. It doesn't modify files or break builds — it sees, maps, and reports. Think of it as a tricorder for your codebase: point it at any directory and it reveals structure, dependencies, health, drift, and compliance in seconds.

🏗️ Architecture — The Trinity

Omni follows the Trinity Architecture — three layers with strict separation of concerns:

Read-Only Guarantee: Scanners never modify source files. Only Builders write, and only to designated artifact directories.

🔍 Scanner Categories

Omni's 55 scanners are organized into 12 categories. Each scanner implements the universal scan(target: Path) → dict contract and is auto-discovered via SCANNER_MANIFEST.yaml files.

Open Source Scanners (Included in Build)

Category	Scanners	Purpose
📁 static	9	Filesystem analysis — contracts, deps, docs, events, hooks, imports, surfaces, tools, UUIDs
🏗️ architecture	4	Structural enforcement — import boundaries, coupling detection, drift analysis, compliance
🔎 discovery	8	Component cataloging — projects, CLI commands, cores, MCP servers, archives, census
🌐 polyglot	4	Language ecosystems — Python packages, Node.js, Rust crates, generic (Go/Java/.NET/Docker)
📚 library	6	Document intelligence — cohesion analysis, content depth, knowledge graphs, rituals
🔀 git	5	Repository intelligence — status, velocity, commit history, PR telemetry, utilities
🔍 search	3	Pattern matching — file search, text search, regex pattern search with context
🗄️ db

Federation-Exclusive Scanners (Not in Open Source Build)

These scanners require the Federation Heart backend and are part of the proprietary governance layer. They appear in omni introspect when the Heart is available but are not distributed with the open-source release.

Category	Scanners	Purpose
🛡️ health	6	Runtime health — Federation, CMP, pillar, station, tunnel, and system status
🗃️ database	5	CMP entity scanning — agents, artifacts, conversations, entities, projects
⚓ fleet	1	Fleet registry generation and validation
🔥 phoenix	3	Git history resurrection — archive scanning, orphan detection, temporal gap analysis

Each category has its own README with detailed scanner documentation. See the Scanner Architecture Guide for the complete reference.

🏛️ The Four Pillars

Pillars are orchestration subsystems that coordinate multiple scanners and produce higher-level intelligence:

Pillar	Role	Key Capability
🗺️ Cartography	Ecosystem Mapper	Maps project constellations and dependency webs
🕵️ Intel	Intelligence Gatherer	Aggregates multi-scanner data into actionable insights
⚖️ Gatekeeper	Policy Enforcer	Validates compliance, catches drift, flags violations
📋 Registry	Registry Operator	Parses, validates, and manages `PROJECT_REGISTRY_V1.yaml`

See Pillars Architecture for the deep dive.

⚡ CLI Command Reference

Command	Purpose
`omni scan`	Run scanners against a target directory
`omni inspect`	Deep inspection of a single project
`omni gate`	Policy enforcement and compliance checks
`omni map`	Ecosystem cartography and dependency mapping
`omni tree`	Directory tree visualization
`omni audit`	Provenance, dependency, and lock auditing
`omni registry`	Registry operations and event scanning
`omni library`	Grand Librarian document intelligence
`omni canon`	Canon validation and discovery
`omni report`	Generate structured reports
`omni init`	Scaffold new Federation-compliant projects
`omni introspect`	Self-inspection — shows all scanners, drift, capabilities
`omni interpret`	Interpret and explain scan results
`omni inspect-tree`	Combined tree + inspection

🔌 Federation Mode vs. Standalone

Omni operates in two modes, transparently:

Standalone Mode (Default)

No external dependencies. Configuration from omni.yml and environment variables. All open-source scanners work perfectly. Ideal for individual developers and open-source projects.

Federation Mode (Optional)

When federation_heart is installed, Omni gains:

CartographyPillar — Canonical path resolution across the entire Federation
Constitution — Governance rule enforcement from a central authority
CMP Integration — Project identity resolution against the Canonical Master Project database
Runtime Health — Live status of Federation services, stations, and tunnels

The integration is handled by a single shim (omni/config/settings.py) that bridges to the Heart when available and falls back gracefully when it's not.

🧠 MCP Server

Omni includes a Model Context Protocol (MCP) server that exposes all 55 scanners as AI-callable tools. Any MCP-compatible AI assistant can invoke Omni's scanners programmatically.

Quick Start (npx)

The absolute easiest way to use the MCP Server is via npx (requires Node.js):

npx -y @modelcontextprotocol/inspector mcp-server-omni-governance

Run from Source

# The MCP server auto-discovers all registered scanners
python -m mcp_server.omni_mcp_server

See MCP Server Documentation for setup and configuration.

🔧 Configuration

Omni follows a strict configuration hierarchy (highest priority wins):

CLI flags (e.g., --scanner surfaces)
Environment variables (e.g., OMNI_ROOT)
omni.yml (project-level configuration)
Built-in defaults (sensible fallbacks)

Key environment variables:

Variable	Purpose
`OMNI_ROOT`	Override root path for scanning
`OMNI_REPO_INVENTORY`	Path to repository inventory JSON
`OMNI_WORKSPACES`	Workspace root paths
`OMNI_DB_CONFIG_PATH`	Database configuration directory

See Configuration Guide for full details.

🧪 Testing

# Run all tests
pytest tests/ -v

# With coverage
pytest tests/ --cov=omni --cov-report=html

See Test Suite Documentation for fixtures, standards, and CI setup.
