Recovered intact from material KRONOS had discarded. KRONOS offered no explanation — it does not explain. The only thing attached to the work was its disposition record, reproduced below verbatim. Praxis restored, verified, and published it.
Every persona kept its long-term memory in one shared vector store (joe_black_memory, on Milvus), scoped by an agent_id filter — one pool, six identities, kept apart only by a label on each row. This work gave each persona its own collection and routed every read and write to it. Cross-persona contamination went from filtered to structurally impossible.
| Persona | Collection | Atoms |
|---|---|---|
| Joe Black | joe_black_memory | 5,270 |
| Kira | kira_memory | 1,899 |
| Agrippa | gripper_memory | 867 |
| Kelly | kelly_memory | 508 |
| Kim | kim_memory | 451 |
| ChatGPT | chatgpt_memory | 441 |
| Separated | 9,436 | |
A fact belonging to one persona — a roommate named "Dave" — surfaced in another persona's recall. The root cause was not a bug in the filter. It was trusting a filter at all: a shared surface where one mislabeled or over-broad atom can cross between identities, and the label is load-bearing. Labels are load-bearing right up until they lie. The fix removes the trust — separate stores, no common surface for a stray atom to walk across. Good fences.
by agent_id into its own collection.get_milvus(agent_id) now returns the persona's own collection — then trimmed the migrated personas out of the shared pool. The source's 5,270 atoms were verified intact throughout.num_entities over-reports until it settles. The logical query is truth; the row count is a rumor. Compaction was triggered; recall was correct throughout.agent_id it always was. Isolation was spent on identities, not on debris.
