# InterfaceCanon Core
Maintain one focused domain model extending InfoTechCanon. `canon.yaml` is the
entry-point registry. Models live under `infospace/models/`; standards, if later
needed, belong under `infospace/standards/`. Workplans stay in the repository shell.
CommerceCanon is the structural precedent, not an imported commercial dependency.
Every new term must have a definition, distinguishing counterexample, source
locator or explicit local rationale, and an ownership disposition. Preserve FIAM
identifiers in mappings; do not relabel protocol families as primitive entity types.
Import shared roots from their owner. A name collision requires an explicit
mapping and review, not a silent replacement or an assertion of equivalence.
Changes to source pins require review of changed semantics and a work record.
Keep previous manifests in Git history. A draft may expose unresolved mappings;
stable promotion requires their resolution and named consumer evidence. Do not
represent availability as adoption or a local card as reciprocal federation acceptance.
FIAM Core facts, exchange profiles, derived indexes, and policy/lens conclusions
remain separate layers. This canon summarizes terminology; FIAM owns wire formats,
validation, conformance, and implementation behavior.
