Abstract: ABSTRACT SYSTEM AND METHOD FOR RATCHETED CRYPTOGRAPHIC CHAINING OF AGENT TOOL CALL RECORDS USING PERFORATION MORPHOLOGY A system for recording artificial-intelligence agent tool-call events comprises a host-agent subsystem (100) having a tool-call intercept (102), chain- state manager (104), log store (108), execution gate (106), and secure element (206). A recorder peripheral subsystem (200) comprises an actuator driver (210) and a solenoid actuator (300) driving a punch (302) against an anvil (304) to form an irreversible perforation (502) in a heterogeneous medium. An index drive (314) advances the medium so the perforation (502) registers within a read aperture (410), where an optical read head comprising an illuminator (400) and an imager (408) captures a measurement of a fracture edge. A fuzzy extractor (220) derives an extracted value and helper data (602). The secure element (206) derives a successor chain key from the current chain key and extracted value, erases the current chain key from memory (208), and releases an acknowledgment signal (202) opening the execution gate (106).
