govern state.

Deterministic Co-Window Integrity Protocol

A receiver-side structural admissibility protocol for systems in which incoming input must not advance local state merely by appearing plausible, credible, or authoritative.

01 / Governing boundaryDCIP / Public description

Acceptance by
structural fit.

DCIP replaces acceptance by appearance with acceptance by structural fit at the receiver-side state boundary.

Local state must not advance merely because an incoming input appears plausible, credible, or authoritative.

Replay, relay, cumulative drift, and authority injection do not become valid state transitions merely by remaining plausible or difficult to detect.

01

Replay & relay

Replayed or relayed input does not become a valid state transition merely by remaining plausible.

02

Cumulative drift

Input does not gain structural admissibility merely because cumulative change is difficult to detect.

03

Authority injection

Apparently credible or authoritative input must still meet the receiver-side structural conditions for state change.

02 / Architectural contextDistinct domains. Defined boundaries.

A different boundary: authorised presence.

DCIP addresses structural admissibility before local state change. HCAC addresses continuously proven authorised presence at the protected request boundary.
