/lit-pull Papez circuit anatomy and function — how the hippocampus-fornix-mammillary bodies-anterior thalamus-cingulate cortex loop gates different types of memory encoding across action modes. Target claims: MECH-094 (hypothesis tag / write gating), ARC-007 (hippocampal map navigation). The architectural question: different action modes (habitual, planned, simulated/rehearsed, sleep SWS, sleep REM) have different WRITE PROFILES to the hippocampal system — what gets written, with what fidelity, with what tags. The Papez circuit may provide the anatomical substrate for this gating. Also relevant: the distinction between confabulation (memory system tag loss — MECH-094), psychosis/delusion (DA-related belief updating), and hallucination (sensory prediction dominating input) as three mechanistically distinct failure modes that the current MECH-094 collapses into one.
