From failed traces to draft PR

See one failure group become a review-ready fix.

After your QA or production workflow surfaces failed traces, MEGA Loop groups related cases, finds the upstream cause, validates the candidate fix, and prepares the evidence for review.

Fits your existing workflow

Keep your existing observability stack. Add the self-evolving layer.

Your observability stack collects and stores traces from both QA runs and production traffic. MEGA Loop takes the failed traces your workflow surfaces, then runs the same analysis, fixing, and verification process for both.

Why MEGA Loop

Efficiency and proof over inefficient automation.

MEGA Loop connects related failures to their trace and code dependencies, then verifies each candidate fix against both failed and previously passing cases.

01
Failure groups

See the pattern, not just the failed run.

Related failed traces are grouped so repeated symptoms can be analyzed as one connected problem.

02
Dependency-aware order

Fix causes before downstream symptoms.

Problem relationships, trace steps, and code dependencies reveal what should be fixed first, what may be affected, and what can move independently.

03
Evidence-gated fixes

Know whether the fix holds before review.

A candidate must improve failed cases and preserve previously passing cases across quality, cost, and latency criteria before a draft PR is prepared.
