13+ hour C++ algorithm accuracy run

An independent user reported a >13h multi-stage C++ accuracy task that stayed on goal, found a public code-memory tool, and improved the final precision.

The user reported a clear precision improvement, less context compression, and an explanation that made the result and experiment path understandable after the run.

Case context

A complex C++ algorithm had a precision problem, while direct long-running agent attempts risked parameter thrashing, local-detail drift, and repeated context compression.

Repository evidence

Proof

A >13h engineering run can remain aligned, change method through public research, and retain an understandable evidence trail.

Runtime and outcome are user-reported; the public MCP reference is independently inspectable.

LoopX behavior

1
kept the multi-stage work aligned to the declared vision for more than 13 hours
2
triggered public research when the current route no longer appeared able to satisfy the vision
3
selected a public codebase-memory MCP for C++ call-graph and coupling analysis
4
retained experiment evidence and an explanation of the final approach
