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).

/*
|
|
* Symbol prefix for the vendored SQLite build.
|
|
*
|
|
* The sx JIT resolves #foreign symbols via dlsym(RTLD_DEFAULT), which
|
|
* searches every image already loaded into the process — and the OS
|
|
* libsqlite3 is usually among them, so the standard names would silently
|
|
* bind to the system copy instead of this vendored one. Prefixing the
|
|
* API surface makes resolution unambiguous in both JIT (dlopen) and AOT
|
|
* (static link) modes: dist_sqlite3_* exists ONLY in the vendored build.
|
|
*
|
|
* Only the functions bound in src/db/sqlite.sx are renamed; extend BOTH
|
|
* files together when new API is needed. Injected via `-include` in the
|
|
* Makefile's SQLITE_DEFS, so sqlite3.c and its embedded sqlite3.h see
|
|
* the renames consistently.
