src/db/sqlite.sx declares the vendored amalgamation as a named '#import c' unit (pinned defines + -O2 + #source); every #foreign binding resolves against it with UNPREFIXED sqlite3_* names. sx compiles the unit through its content-addressed object cache — once per checkout — links the objects into 'sx build' binaries, and loads them as a priority symbol target under 'sx run', so the OS libsqlite3 can never shadow the vendored copy (the version pin in sqlite_smoke proves it). Retired: the Makefile vendor targets (cc -> .a + jit/.dylib), the GENERATED dist_sqlite3_* rename.h (the JIT no longer resolves program-owned symbols through the process images, so the rename's reason is gone), and the -L plumbing in make build + tests/run.sh. make test 22/22; otool -L build/dist carries no libsqlite3.

The amalgamation is part of the program, not the build system:
src/db/sqlite.sx declares it as a named #import c unit carrying the
pinned compile options (SQLITE_DQS=0, SQLITE_THREADSAFE=0,
SQLITE_DEFAULT_MEMSTATUS=0, SQLITE_OMIT_DEPRECATED,
SQLITE_OMIT_SHARED_CACHE, SQLITE_LIKE_DOESNT_MATCH_BLOBS,
SQLITE_ENABLE_COLUMN_METADATA, -O2), and every #foreign sqlib
binding resolves against that unit. sx compiles the unit through its
content-addressed object cache (.sx-cache/), so the 250k-line source
builds once per checkout — sx build links the objects into the
binary, sx run loads them as a PRIORITY symbol-search target ahead of
the process images, which is why the OS libsqlite3 (a different
version, loaded into the compiler process by CoreServices) can never
shadow this copy. tests/sqlite_smoke.sx asserts
sqlite3_libversion() equals the version above, so any fallback fails
loudly in both modes.
Bound surface
src/db/sqlite.sx maps the full practical C API (~100 functions):
connection lifecycle + open_v2 flags, errors (extended codes included),
statements with the complete bind/column families, parameter and column
introspection (built with SQLITE_ENABLE_COLUMN_METADATA), incremental
blob I/O, the online backup API, serialize/deserialize, and the library
utilities. Not bound, by design: callback-taking APIs (hooks, UDFs,
collations, authorizers — they need C→sx callbacks), the
sqlite3_value_* family (UDF-coupled), varargs configuration, UTF-16
variants, and subsystems this build omits (mutex/VFS under
SQLITE_THREADSAFE=0, sessions/snapshots/vtabs, deprecated API).
To upgrade: replace sqlite3.c/sqlite3.h with a newer amalgamation,
update this file and the version constant in tests/sqlite_smoke.sx,
and run make clean test (the object cache keys on the source bytes,
so the new amalgamation recompiles automatically).
