How to query the INITE Brain knowledge graph across time — the asOf parameter, validFrom/validUntil semantics, reading retracted facts, and the memory_diff "what changed between two cursors" surface. Use when the user's question has a temporal dimension ("on X date", "before Y", "what's new since last conversation").
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# brain-bitemporal Brain is a bitemporal store. Every fact carries **two** time axes — when it was true in the real world (`validFrom`/`validUntil`) and when brain knew about it (`recordedAt`/`retractedAt`). Most agent code can stay on the "actual now" default; this skill is for when the user's question demands otherwise. ## The two axes | Axis | Field pair | Meaning | | --- | --- | --- | | Valid time | `validFrom` / `validUntil` | When the fact was true in the world. `validUntil` open-ended (`null`) means "still true". | | Transaction time | `recordedAt` / `retractedAt` | When brain learned the fact / when brain learned it was wrong. `retractedAt = null` means "still believed". | Examples: - Alice was *gold tier* from 2026-02-01 to 2026-04-01, then upgraded to *platinum* — two facts, sequential `validFrom`/`validUntil`. Neither is wrong; one succeeds the other. - Brain recorded Alice's tier on 2026-03-15 from an inbox message, then learned on 2026-04-10 that the message was misattributed — fact retracted, but the row stays for audit. ## The default is "actual now" …

How to install
mdr add inite-ai/inite-brain-service/brain-bitemporal@sha256:a83c69a5d0687a1fThe line at the top of this page pins the label git:20261101.60e41ae, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
