Develop

For people changing the code: how the modules are wired, how the test pyramid runs, and what performance claims are allowed to look like.

Contributor workflow (branch model, commit format, CLA, PR checklist) lives in CONTRIBUTING.md at the repository root, because GitHub renders it in the pull-request sidebar.

In this chapter

Page	What it gives you
Testing	The pyramid — unit, golden, property, simulation, model checking, upgrade matrix — plus the reproduction discipline
Benchmarks	The benchmark matrix, the noise-control protocol, and the rules for drawing conclusions

Planned pages

• Module boundaries and extension points — how to add a new op, a new metric or a new config key without breaking the allowlists
• Storage internals — segment format, sparse index, checkpoint replay
