ARIA - Adaptive Runtime Intelligence Architecture

The cognitive CLI for self-narrating systems

---

What is ARIA?

ARIA is the cognitive layer that makes systems explain themselves.

It connects to live runtimes, observes their state, and generates natural language explanations of what's happening and why. ARIA turns opaque systems into self-narrating organisms.

aria serve

Start the cognitive server.

aria serve                                   # Start with defaults
aria serve --brain phi2                      # Use specific brain

aria serve --host 0.0.0.0                    # Bind to all interfaces
aria serve --reload                          # Auto-reload on changes

aria tour

Run guided cognitive tours.

aria tour list                               # List available tours
aria tour run cognitive-loop.json            # Run a tour
aria tour validate tour.json                 # Validate tour file
aria tour create --name "My Tour"            # Interactive tour creation

aria session

Record cognitive sessions.

aria session start --name "debug-session"    # Start recording
aria session stop                            # Stop recording
aria session list                            # List all sessions
aria session show session-123                # Show session details
aria session export session-123 --format json
aria session replay session-123              # Replay a session

aria holomap

Manage Holomap world files.

aria holomap validate world.hmap             # Validate a holomap
aria holomap diff old.hmap new.hmap          # Diff two holomaps
aria holomap stats world.hmap                # Show statistics
aria holomap visualize world.hmap            # Open visualization

aria watch

Live monitoring with real-time narration.

aria watch http://localhost:8080             # Watch live endpoint
aria watch --interval 5                      # Poll every 5 seconds
aria watch --alert "load > 80%"              # Alert on condition

---

Configuration

ARIA uses ~/.aria/config.toml for configuration:

[brain]
default = "tinyllama"
path = "~/.aria/models"
timeout = 30

[server]
host = "127.0.0.1"
port = 7777

[session]
output_dir = "~/.aria/sessions"
format = "jsonl"
compress = false

[style]
theme = "dark"
verbosity = "normal"

---

Python API

from aria import CognitiveEngine, WorldSnapshot

# Initialize engine
engine = CognitiveEngine(brain="tinyllama")

# Create snapshot
snapshot = WorldSnapshot.from_file("state.json")

# Generate explanation
response = engine.explain(snapshot)

print(response.summary)
# "Trinity Core is cycling at 847 events/second, 
#  indicating healthy recursive processing."

print(response.focus_nodes)
# ["LenixTrinityEngine", "WaterwheelHub"]

Async API

import asyncio
from aria import AsyncCognitiveEngine

async def main():
    engine = AsyncCognitiveEngine(brain="phi2")
    
    async with engine:
        response = await engine.explain_async(snapshot)
        print(response.summary)

asyncio.run(main())

Session Recording

from aria import SessionRecorder

with SessionRecorder("my-session") as recorder:
    # All cognitive events are automatically recorded
    response = engine.explain(snapshot)
    
# Session saved to ~/.aria/sessions/my-session.jsonl

---

The Cognitive Contract

ARIA implements the Explainer Contract:

Input:  WorldSnapshot (nodes, flows, metrics, focus)
Output: ExplainerResponse (summary, details, focus_nodes, confidence)

Every explanation is:

• Grounded — references only nodes/flows that exist
• Bounded — respects token limits
• Deterministic — same input → consistent output
• Traceable — includes confidence and reasoning
