Qdrant Foundation

Use when porting or re-implementing filtered vector-search machinery: filterable HNSW builds, ACORN/graph dispatch decisions, cardinality-driven prefilter-vs-index planning, WAL durability, hybrid RRF fusion, prefetch-tree query planning, or flush-ordered post-optimize cleanup. Source code and direct tests are ground truth; references carry decisive excerpts and graph retrieval.

Qdrant: vector-engine foundations

Foundation contract

This is a cold, source-specific foundation, not an operational procedure. It is historical, revision-pinned evidence rather than timeless guidance. Current project source, tests, requirements, and runtime behavior outrank this projection and decide what ships.

Provenance and revision

Source record: qdrant; portable upstream identity, license, coverage caveats, and retrieval history are preserved in the index.
Recorded revision: master@74f3e85b9473c62560006c043e13737ce6b48412.
Full provenance, coverage caveats, boundaries, and preserved evidence: references/index.md.

Topic map

Representative topics: Filtered HNSW build; Payload subgraphs; ACORN dispatch; Graph-with-vectors; Quantized search; Estimator; Sparse dispatch; WAL format.
Scope and retrieval questions: references/index.md#use-this-for.
Complete capsule chooser: references/index.md#load-the-matching-source-dump.
Detailed grouped map: references/index.md#capsule-map.
Source limitations and portability boundaries: references/index.md#boundaries.

Retrieval

Open the index, choose one capsule matching the active question, and load only that capsule. Revalidate its cited source and revision before relying on it. Do not bulk-load the inventory, treat historical claims as current truth, or apply this foundation as a procedure.
