Technical Contracts

This section is FEMIC’s compact technical contract surface.

Use it when you need a fast answer about repo invariants, runtime prerequisites, path resolution, stage boundaries, canonical artifacts, or restart behavior.

This is intentionally not a separate agent-only documentation universe. The pages here live in the same Sphinx tree as the narrative Guides and API Reference, and they link back to those deeper pages instead of duplicating them wholesale.

How to use this section

• Start here when you need the shortest source-of-truth answer for an operational seam.

• Follow the linked Guides when you need the full runbook or interpretation detail.

• Follow the linked API pages when the question is really about code ownership or callable behavior rather than workflow contract.

Contract Pages

• Patchworks Model Semantics
• Repo and Runtime Invariants
• Instance and Data Roots
• Instance Extension Boundaries
