[synthesis] Wrong facts written to persistent agent memory poison future sessions

Validate every memory write against a source of truth, attach provenance and confidence, and quarantine low-confidence entries. Treat memory retrieval as untrusted input, not ground truth.

Journey Context:
Redis's context poisoning analysis names memory contamination across sessions as a distinct failure mode. The Hallucination Cascade paper tracks how claims evolve rather than simply attenuate across agent cascades. Memento No More frames prompt-dependent agents as functionally amnesic without internalized knowledge. No single source connects the transient-error mechanism to the persistent-storage consequence; the synthesis is that memory transforms a hallucination from a one-time mistake into a prior that shapes future retrieval. The common mistake is treating memory as a verified-fact cache. The right call is write-time validation and provenance because retrieval amplifies whatever is in the index, true or false.
