How OIM works.
OIM is deliberately small. It accepts a packet, evaluates structural completeness, returns a deterministic result, and stops.
Packet assembled
A workflow, model, caseworker, or application creates a decision packet with declared options, assumptions, metadata, authority references, and declared invalidation conditions.
OIM evaluates structure
OIM checks only whether required fields exist and satisfy minimum structural requirements. It does not interpret the meaning of those fields.
Outcome returned
OIM returns STRUCTURALLY_VALID or STRUCTURALLY_INSUFFICIENT with deterministic errors and a packet fingerprint.
Runtime decides execution
A separate runtime, institution, or authority layer decides whether structural validity may become execution authority.
Audit trail preserved
The fingerprint and evaluation record create a reproducible structural evidence artifact for review, replay, or downstream governance.
