Canary Fabric v0.2.1

Key Capabilities

  • OWASP ASI08 Multi-Agent Blast Radius Circuit Breaker: Implements BlastRadiusCircuitBreaker with sub-millisecond rolling FIFO window tool-call velocity monitoring per agent.
  • Progressive Strike Decay: Automatically decays accumulated strikes over configurable quiet windows, preventing permanent lockouts from transient traffic spikes.
  • Half-Open Probationary Recovery: Safely transitions tripped agents through a probationary period before fully restoring active status.
  • Bounded Ephemeral Agent Pruning: Automatically prunes idle and dead agents beyond capacity limits, guaranteeing deterministic O(1) memory consumption in high-churn multi-agent swarms.
  • 100% Unit Test Coverage: Verified across 100 unit tests with sub-millisecond tripwire latency.

Canary Fabric v0.2.0: Invisible Cryptographic Tripwires & Streaming Circuit Breakers for RAG & Autonomous AI Agents

canary-fabric is a deterministic, wire-level data exfiltration defense system for Retrieval-Augmented Generation (RAG) and autonomous AI agent runtimes.

⚡ 60-Second Quickstart (Zero External Services)

Run the self-contained verification demo in <1 second with zero infrastructure dependencies:

git clone https://github.com/invarcore/canary-fabric.git && cd canary-fabric
pip install -e .
python examples/quickstart.py

🛡️ Core Capabilities & Invariants

  • 4-ary Zero-Width Cryptographic Steganography:
    • Injects 64-bit HMAC-derived canary tokens (\u200B, \u200C, \u200D, \uFEFF) invisibly into retrieved chunks.
    • 100% imperceptible to human reviewers; preserved across standard LLM tokenizers.
  • Sub-Millisecond Wire-Level Streaming Circuit Breaker:
    • SlidingWindowStreamBuffer scans outbound Server-Sent Events (SSE) and agent tool-call JSON in real-time.
    • Micro-benchmark: 17.73 µs scan latency per chunk (< 0.05 ms Time-to-First-Token tax, 50,000x faster than synchronous LLM/NER guardrails).
    • Severs rogue egress streams before customer PII or confidential IP is rendered or transmitted.
  • Synthetic Decoy Honeytokens:
    • High-fidelity synthetic credentials (sk_live_canary_..., PostgreSQL connection strings, AWS secrets, canary emails) for honeypot documents and data trap monitoring.
  • Tamper-Evident Forensic Leak Certificates:
    • Emits HMAC-SHA256 authenticated forensic certificates cryptographically binding each breach to its source document chunk, tenant namespace, and prompt hash.
  • Turnkey Ecosystem & Framework Adapters:
    • Native drop-in adapters for LangChain, LlamaIndex, FastMCP, Knowledge Fabric, Intent Fabric, and OpenAI/LiteLLM streaming wrappers.

🧪 Quality Gates & Verification Suite

  • Unit & Integration Suite: 90/90 passed (100% green across Python 3.11, 3.12, 3.13).
  • Code Coverage: 97.41% (exceeding strict 90% threshold).
  • Docker Verification: Hermetic Docker Compose test suite verified.
  • Packaging: Built and signed wheel and sdist distributions attached.
