  "purpose": "Govern memory separation by observable namespace before any remembered material can influence DEVON-DEV execution.",
  "function": "Define memory partition boundaries by project, workspace, agent, user, session and memory class so retrieval, write, update and delete operations cannot cross scope without explicit policy approval.",
  "overview": {
    "summary": "Partitioned Memory Canonical is the boundary layer that prevents DEVON-DEV memory from becoming one undifferentiated pool of remembered context. It decides how memory is separated before Memory Lifecycle can expire it, Knowledge Versioning can revise it or Learning Governance can treat it as eligible signal.",
    "function": "FUNCTION: Bind every memory operation to an observable namespace, memory class, owner scope, retrieval permission, write authority, update rule, delete rule and cross-boundary denial policy.",
    "system_position": "Memory Lifecycle controls duration and disposal. Knowledge Versioning controls revision history. Learning Governance decides whether a memory-derived signal may teach the system. Partitioned Memory sits upstream of those categories because none of them are safe if the original memory scope is ambiguous.",
    "failure_impact": "The damage pattern is cross-scope contamination: a client memory can influence another workspace, a session residue can look institutional, or a global note can be retrieved as if it were approved canon. This category keeps memory useful without letting it become uncontrolled authority."
