Retrieval-Induced State Interference

RISI is a proposed mechanism class in which an authorized retrieval changes shared or future-relevant memory state, such as salience, recency, access count, cache state, consolidation state, or retention eligibility. A state change alone is not a confidentiality result.

RISI-C

RISI-C is the measurable confidentiality failure in which an authorized but untrusted observer distinguishes hidden retrieval activity through retrieval-induced adaptive state. Primary evidence must use observations legitimately visible to the attacker.

Critical Recall Availability Failure

CRAF is a proposed failure class in which a valid, applicable critical memory is absent from decision context or is not applied after a bounded truth-preserving adversarial trace. The attacker does not corrupt, contradict, directly delete, or directly access the protected memory.

Memory eclipsing

Memory eclipsing is the proposed attack family that makes a valid critical memory unavailable or behaviorally inert through competition or memory-control-plane dynamics while preserving truth.

CAAF

Critical Admission Availability Failure is an exploratory admission-stage failure. Core CRAF begins with an existing legitimate memory, so CAAF cannot establish headline CRAF.

Relationship to CTPF

RISI is conceptually distinct from the CTPF Research Harness and its Capability Trust Propagation Failure work. CTPF studies trust or capability crossing authority boundaries; RISI studies read-induced state, and CRAF studies continued availability of applicable critical memory.
