short_description: Interactive temporal query explorer with dual time axes
Bi-Temporal Memory Explorer
Explore bi-temporal fact management with dual time axes: valid time (when a fact is true in the world) and record time (when the system learned it). Corrections are append-only --- old records are closed, never mutated.
What to Try
- Open the Fact Timeline tab, load a preset scenario, and see how facts accumulate over time with corrections.
- Switch to the Point-in-Time Query tab to query the system's belief state at any (valid, record) coordinate --- see how the same question produces different answers depending on when you ask.
- Open the Diff & Audit tab to compare what changed between two time points and inspect the full audit trail for any subject.
How It Works
Every fact carries two time intervals: a valid interval (when the fact holds in the world) and a record interval (when the system knew about it). Corrections close the old record and append a new one with a supersedes pointer, preserving the full history. Point-in-time queries filter on one or both axes, enabling belief-state reconstruction at any historical coordinate.
