The exhibit
EXHIBIT A · BITEMPORAL GROUNDING
Two clocks. Never collapsed into one.
A memory stored with an event date years apart from the date of the conversation it was extracted from, as reported in mem0's public issue tracker (issue #3944). Reported there, not verified here.
errata · the same shape of transcript:
event_time 2023-05-07 · ingest_time 2026-08-17 · both stored, both queryable, forever
event_time 2023-05-07 · ingest_time 2026-08-17 · both stored, both queryable, forever
Two clocks, never collapsed: when it happened, and when we learned it. A memory that keeps only one of them has to guess at the other — and a guessed date is indistinguishable, downstream, from a recorded one.
