Memory & Epistemic State Management

The coreason-runtime manages episodic events, trace contexts, and capability telemetry through a high-throughput, Arrow-native Medallion Architecture. This system ensures that the continuous generative output of multi-agent topologies is deterministically unified, indexed, and stored without starving the asynchronous execution plane.

1. The Medallion Data Pipeline

Telemetry and state transitions flow through three distinct epistemic layers:

  1. Bronze Layer (Raw Ingestion): High-velocity Server-Sent Events (SSE) and raw JSON-RPC logs are captured continuously. The ContinuousStreamBuffer manages memory backpressure using a probabilistic forget-gate driven by strict spatial SHA-1 hashing, ensuring zero distributed CRDT state forks during load shedding.
  2. Silver Layer (Entity Resolution): The PolarsSilverGate cleanses, normalizes, and assigns deterministic cryptographic identities to all events.
  3. Gold Layer (Latent Aggregation): Unified traces are structured into capability metrics, topological usage graphs, and long-term sovereign memory.

2. High-Velocity ETL (The Silver Gate)

To unblock the uvloop async reactor during massive burst-ingestion scenarios, the Silver Layer entity resolution pipeline operates entirely outside the Python Global Interpreter Lock (GIL) using Apache Arrow and Polars.

GIL Eradication & Vectorization

The runtime adheres to a strict "Borrow Over Build" mandate for cryptographic operations. Rather than utilizing slow, scalar Python for loops or maintaining custom Rust pyo3-polars extensions, the pipeline leverages the polars-hash namespace. * Cryptographic hashing is executed natively in Rust across contiguous Arrow memory arrays. * The Python GIL is entirely bypassed during massive parallel data transformations.

Vectorized Cryptographic Forgery (UUIDv5)

The Silver Gate generates deterministic identities (entity_uuid) based on composite natural keys (e.g., intent_id + workflow_id). To satisfy strict downstream schema requirements (RFC 4122 UUIDv5) without sacrificing SIMD throughput: 1. The pipeline generates an $O(1) vectorized SHA-1 digest over the CoReason namespace and the composite key. 2. It utilizes vectorized regex substitution to mathematically inject the required Version (5) and Variant (8) bitmasks into the raw hash string. 3. The result is a mathematically perfect, schema-compliant UUIDv5 generated at maximum hardware memory bandwidth.

Shuffle-Invariant Idempotence

The Silver Layer guarantees strict mathematical idempotence. Extensive property-based fuzzing ensures that regardless of network jitter, micro-batch chunk sizing, or the arrival order of out-of-sequence events, the generated entity_uuid outputs remain 100% identical and deterministic.

3. Sovereign Storage & Fallback (LanceDB)

While the runtime relies on the coreason-ecosystem for global URN resolution, it maintains a localized sovereign memory matrix using LanceDB.

  • Latent Memory: Agent embeddings, episodic RAG documents, and execution traces are persisted locally in LanceDB, enabling $O(1) memory retrieval during rapid workflow rehydration.
  • Network Partition Resilience: If the EcosystemRegistryClient fails to reach the global capability registry during a Master MCP publication (Epistemic Crystallization), the runtime gracefully falls back to logging the EpistemicPromotionEvent directly into the LanceDB sovereign store, ensuring zero data loss during network degradation.
