The Problem: Traditional architectures force a trade-off between memory depth and context limits, causing linear token expansion and out-of-memory errors at scale.
The Solution: EDR Context Engine processes and offloads streaming telemetry directly to an indexed operational state archive under the model.
The Result: The background storage layer is designed to scale independently of active working context into gigabytes of data while active working context remains strictly bounded at ~372 tokens (mean), regardless of archive depth.
EDR Context Engine™ completes the run on a single workstation-class GPU (A4000).
Full replay baselines scale active working context length linearly with operational history (yielding quadratic cumulative attention/compute scaling over the session). EDR Context Engine maintains a bounded active working context.
EDR Context Engine is a programmable memory/session layer that keeps active working context bounded while archive size grows.
Scope: real nuPlan telemetry replay · bounded-memory evidence run · reconstruction verification
· grounding metrics.
Production certification, regulated compliance, and adversarial safety validation are separate review lanes.
EDR Context Engine does not ask the model to carry the entire transcript forward. It records, verifies, and retrieves compact evidence from a growing archive while keeping active working context bounded.
During this benchmark, the Full Replay Baseline continuously expands the model's active working context as history accumulates. EDR Context Engine maintains a bounded active working context regardless of archive growth. Note: This baseline represents brute-force context stuffing. Optimized approaches (such as prefix caching, vector retrieval, graph memory, or state-space models) are planned for future benchmark lanes.

This repository is not a pitch deck. It is a reproducible benchmark harness. The goal is to let engineers test long-session memory strategies against identical archives, identical questions, identical scoring rules, and transparent artifacts.
If you believe another memory architecture performs better, run it through the same benchmark harness. The point is not to argue from claims. The point is to produce comparable artifacts.
All 13 observed retrieval recall failures were classified as near-duplicate stationary telemetry ambiguity.
Root Cause: These misses occurred exclusively during periods of stationary or near-stationary vehicle behavior, where successive telemetry frames had identical GPS coordinates and telemetry payloads.
Resolution: Future iterations will incorporate temporal sequence hashing to differentiate between static frames with identical spatial coordinates.
Decoupling session history from active context guarantees flatline compute requirements. This page evaluates runtime execution metrics, throughput stability, and task-level inference efficiency under continuous ingestion.
Maintains stable end-to-end task execution latency across extended stream depth.
Bounded active context sizes prevent TTFT degradation.
Consistent transaction speed under continuous ingestion.
Highly optimized work output per unit of energy.
Inference remains stable because only the active working set is presented to the model regardless of operational history.

Four things you can verify yourself in under two minutes by opening the file above.
In a legacy system the prompt_tokens field grows linearly with every turn appended to context. At 1,500 tokens per turn, by cq-200 the prompt would be 300,000+ tokens and still climbing. Here it is completely flat from start to finish. The bounded memory layer handles growth - the model never sees it.
Core steady-state band. The bulk of rounds cluster right around 2,400ms to 3,100ms - the same tight window from cq-002 to cq-200. That window is the raw backing data behind the p50 = 2,688ms figure shown in the latency table. The rhythm does not drift. There is no warmup period past the first call and no degradation at the end. Throughput holds flat across 200 rounds spread over 7.69 hours.
This is the unedited signature of a system spinning up: cold cache population and model weight loading into GPU memory happen once on the first call, then execution flattens immediately. Every call from cq-002 onward is in the 2-4 second steady-state band with no exception. The log has not been cleaned or filtered.
Every single line of model-calls.jsonl carries "model":"qwen2.5:7b". This is a 7-billion-parameter local model with no cloud backend. The flat 1,500-token prompt window is what makes it viable at scale. At 300,000-token context sizes a model this size would be unusable - that is the entire point.

| p95 | 3,316 ms | 95th percentile. Tail is tight - only 628ms above median. |
