Codedb Foundation

Use when building or porting codedb-style code-intelligence search engines — typo-substring trigram indexes with bloom pruning, inverted word indexes with BM25+ ranking, content-defined n-gram indexes, mmap zero-copy persistence, deterministic call/import graphs, generation-safe result caches, and tiered recall ladders for agent context tools. Source code and direct tests are ground truth; references carry decisive excerpts and graph retrieval.

codedb: Code-Intelligence Search Engine Foundation

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: codedb; portable upstream identity, license, coverage caveats, and retrieval history are preserved in the index.
Recorded revision: main@43bc3ca2.
Full provenance, coverage caveats, boundaries, and preserved evidence: references/index.md.

Topic map

Representative topics: Zero-copy word index; Removal dual-path & shard parity; Bloom posting masks; Regex prefilter compiler; Sparse n-grams; Overlay lattice; Two-file disk format; Tier ladder.
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.
