Concept Map

Contracts

• Execution contract defines determinism and replay guarantees.
• Implicitness contract requires explicit opt-in for persistence and approximation.

Determinism vs ANN

• Deterministic: bit-identical results when replayed.
• ANN: approximate results, explicitly labeled experimental until criteria are met.

Storage vs Execution

• Storage holds documents, chunks, vectors, and artifacts.
• Execution runs algorithms over stored vectors under a declared contract.

Provenance

• Provenance explains how a result was produced.
• Embedding metadata and vector store metadata must be present when used.

Trust Boundaries

• Execution engine is deterministic only when every component declares determinism.
• External backends (VDB/ANN) must be explicitly configured.
