Crate kmp_adapter_embedded 

Embedded edition storage adapters (ADR-009).

One EmbeddedKernelStore opens one data directory (ADR-012 layout: FORMAT_VERSION + store/kernel.redb) and implements every persistence port the kernel needs: graph reads (materialized adjacency per ADR-010), node details, the append-only context event log, projection runtime state, and snapshots. Commits are fsync-durable (redb immediate durability), so the crash contract is: no data loss beyond the in-flight event, no duplicate application on replay.

The observable semantics are pinned by kmp-conformance: the same suite that certifies the in-memory kernel store and the Neo4j/Valkey adapters runs against this store.

Structs

BundleHeader

First line of a bundle file: integrity metadata for fail-fast import.

EmbeddedKernelStore

Every kernel persistence port on one local redb file.

ImportReport

Outcome of an import: events replayed and projections rebuilt.

ProjectionRebuildReport

Outcome of a projection rebuild from the append-only event log.

QualityTelemetryRetention

Bounded-journal policy for local quality observations.

RedbQualityTelemetryReader

Read-only query adapter for the local quality journal.

RedbQualityTelemetryWriter

Relaxed-durability writer for telemetry/quality.redb.

StoreMigrationReceipt

What a migration did, kept in the store it produced.

Constants

BUNDLE_FORMAT_VERSION

SUPPORTED_FORMAT_VERSION

Store format version this binary reads and writes.
