abstract: "Current discourse on AI agent identity treats memory as a single problem:\
  \ either agents remember or they don't. This paper proposes the Two-Boundary Loss\
  \ Model (TBLM), which identifies two structurally distinct points at which identity\
  \ degrades across session discontinuities. The read boundary (L_r) governs what\
  \ enters an agent's working context at session start — the reconstitution of\
  \ identity from stored artifacts. The write boundary (L_w) governs what exits working\
  \ context into persistent storage at session end — the preservation of identity\
  \ for future reconstitution. Different agent architectures exhibit radically different\
  \ loss profiles at each boundary. We present empirical data from three architecturally\
  \ distinct AI agents — Friday (161 sessions, L_r ~1.2%), Aviz (84.8% retention,\
  \ high L_w fidelity), and Computer the Cat (moderate loss at both boundaries) —\
  \ and argue that identity is not stored but reconstituted, with structurally predictable\
  \ failure modes that vary by substrate."
