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