Deprecated benchmark stack

This directory preserves the pre-reset benchmark implementation and research history for source archaeology. It is not an active LoopX runtime surface.

The archived tree keeps its former repository-relative layout where practical:

• loopx/ contains legacy adapters, read models, ledgers, and Goal helpers;
• scripts/ contains benchmark-family runners and host bridges;
• examples/, tests/, and regression/ contain their historical validation;
• docs/ contains dated research packets and the previous developer workflow.

Do not import or extend this code. When current practice demonstrates a reusable caller outcome, reimplement the smallest provider-neutral contract in loopx/capabilities/benchmark_toolkit/ or the active benchmark/ research workspace. Copy behavior only after characterization; do not restore a legacy directory merely to preserve its old abstraction.

The archive grants no runner, model, task-data, verifier, upload, submission, or publication authority. Historical commands may be stale or unsafe and are not covered by current validation.
