Subplan 02 Slice 2 foundation. vendor/sqlite/ holds the amalgamation (provenance + upgrade notes in its README); make build compiles it into build/vendor/libsqlite3.a (statically linked into dist via -L) and build/vendor/jit/libsqlite3.dylib (dlopen'd by sx run via tests/run.sh's -L flag) — separate directories because the macOS linker prefers a dylib over an archive in one search dir. The sx JIT resolves #foreign symbols via dlsym(RTLD_DEFAULT), where the already-loaded OS libsqlite3 wins by load order — so the vendored build renames its API to dist_sqlite3_* (vendor/sqlite/rename.h, -include'd), making resolution unambiguous in both modes: those symbols exist only in the vendored products. src/db/sqlite.sx binds the renamed surface behind Sqlite/SqliteStmt (open/exec/prepare/bind/step/column/finalize, errmsg, last_insert_rowid, changes, libversion); opaque handles cross the FFI as usize, strings read from sqlite are copied before its buffers die. make test 20/20 (new: sqlite_smoke.sx — pins the loaded version to the vendored 3.53.2, round trip, reopen persistence, BEGIN/ROLLBACK, errmsg; also verified as an AOT binary with no libsqlite3 in otool -L).

Vendored SQLite

SQLITE_VERSIONinsqlite3.h) - Source: https://sqlite.org/2026/sqlite-amalgamation-3530200.zip
- Zip sha256:

sqlite3.c,sqlite3.h(the amalgamation;shell.candsqlite3ext.hdropped — no shell, no loadable extensions) - License: public domain (https://sqlite.org/copyright.html)
make build compiles this into build/vendor/libsqlite3.a (statically
linked into the dist binary via -L build/vendor) and
build/vendor/jit/libsqlite3.dylib (dlopen'd by sx run, which is how
make test executes the test programs). The two locations are separate
on purpose: the macOS linker prefers a dylib over an archive in the same
search directory, and the AOT binary must link the static copy.
tests/sqlite_smoke.sx asserts sqlite3_libversion() equals the version
above, so a fallback to the OS libsqlite3 fails loudly in both modes.
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.
