Project Landing

A replayable memory and evidence layer for adaptive systems.

LiminalDB is an open database for systems that need memory, replay, auditability, and adaptive behavior in one place. It is the storage and evidence layer of the Liminal Stack.

Why it exists

ProblemTraditional storage systems keep records, but often lose the reasoning trail of how an adaptive system changed.

ConsequenceTeams rebuild replay, event sourcing, evidence, and protocol access on top of generic stores.

ContributionLiminalDB provides replayable history and evidence as an infrastructure primitive.

Why it matters

Open access

Protocol and SDK surfaces stay visible instead of hiding state behind one vendor boundary.

Replayable history

Mirror Timeline keeps change history persistent and inspectable.

Stack fit

It acts as the memory and evidence layer beneath routing and runtime components.

What to remember

Adaptive systems need more than storage; they need replayable operational memory.
Open protocol access matters for digital commons infrastructure.
LiminalDB exists to make system change persistent, inspectable, and reusable.
