Trace Index

Trace Index Design

These pages define the stable product and domain ideas behind Trace Index. They explain what the system means independently of one Runtime format, SQL layout, or implementation detail.

Start with What is Trace Index?, then read the Domain Model and the complete Item Semantic Contract. Operational commands, flags, and SQL encodings remain owned by the version-matched Guides and Reference.
