> Embeddings Flow -- Tools for workflows involving semantic embeddings


## Pages in this subsection

- [ef](ef.html.md): ef (Embedding Flow) — a facade for semantic-embeddings user journeys.
- [ef.artifact_graph](ef.artifact_graph.html.md): The `ArtifactGraph` — `ef`’s content-addressed corpus-indexing core.
- [ef.config](ef.config.html.md): The config layer — declarative, content-addressable pipeline specs.
- [ef.corpus](ef.corpus.html.md): The `Corpus` abstraction — `ef`’s source layer (L0) — and change detection.
- [ef.diagnostics](ef.diagnostics.html.md): Staleness diagnostics — has an indexed corpus drifted from its source?
- [ef.embedder_adapters](ef.embedder_adapters.html.md): Concrete `Embedder` adapters and the DI seam.
- [ef.embedder_wrappers](ef.embedder_wrappers.html.md): Composition wrappers for `Embedder`.
- [ef.embedders](ef.embedders.html.md): The `Embedder` facade — `ef`’s embed layer (L3).
- [ef.evaluation](ef.evaluation.html.md): Evaluation hookpoints — measuring retrieval and RAG quality.
- [ef.exploration](ef.exploration.html.md): Layer L5 — *explore* a corpus: project to 2-D/3-D, cluster, label clusters.
- [ef.hashing](ef.hashing.html.md): Content-hashing primitives shared across `ef`’s layers.
- [ef.ops](ef.ops.html.md): The pipeline ops — the callables an `ArtifactGraph` runs.
- [ef.refresh](ef.refresh.html.md): Refresh — keeping an indexed corpus in sync as its sources change.
- [ef.reranking](ef.reranking.html.md): Reranking — a precision pass over retrieved segments (use case F6).
- [ef.segmenter_adapters](ef.segmenter_adapters.html.md): The segmenter dependency-injection seam and the `imbed` registry bridge.
- [ef.segmenters](ef.segmenters.html.md): The `Segmenter` facade — `ef`’s segment layer (L2).
- [ef.segments](ef.segments.html.md): The canonical `Segment` data model — `ef`’s interchange type for L2.
- [ef.service](ef.service.html.md): The HTTP-service bridge — `EfService`, a stateless-friendly facade.
- [ef.source_manager](ef.source_manager.html.md): The search facade — one-shot `ingest()`, `SearchableCorpus`, `SourceManager`.
