github.com/hanzoai/sqlite-vec/cgo compiles the extension into the binary and registers it process-wide (sqlite3_auto_extension) for every connection csqlite opens — one SQLite in the binary, one extension object, no shared library. Layout is dictated by how the C is written: sqlite-vec.c #include's its -diskann/-ivf/-ivf-kmeans/-rescore siblings, so compiling the repo root as a Go package would hand cgo each fragment as its own unit (measured: rescore fails on its first type). cgo/wrapper.c textually includes ../sqlite-vec.c instead — the root stays a plain C tree that upstream merges land on untouched. Differences from upstream's own Go bindings, both deliberate: - sqlite3.h is COMMITTED, copied byte-for-byte from hanzoai/csqlite's sqlite3-binding.h (SQLite 3.53.2) — upstream leaves the include to whatever the system has, so its build only works when libsqlite3-dev happens to be installed, at whatever version it happens to be. The header here can never drift from the library that links. - sqlite-vec.h is generated from sqlite-vec.h.tmpl and committed, so the module is go-gettable without running make. Verified end-to-end with csqlite v0.1.2, not just compiled: vec_version() = v0.1.10-alpha.4 vec0 KNN over float[4] returns exact Euclidean order — [1,0,0,0]->0.0000, [0.9,0.1,0,0]->0.1414 (sqrt .02), [0,1,0,0]->1.4142 (sqrt 2).
