src/db/sqlite.sx grows from the P5.1 subset (~19 fns) to the complete practical surface (~100): open_v2 + flags, extended errcodes + error_offset, txn_state/autocommit, changes64/total_changes64, limits, the full bind/column families (double/blob/zeroblob), parameter and column introspection (built with SQLITE_ENABLE_COLUMN_METADATA), table_column_metadata, statement introspection (sql/expanded_sql/ readonly/busy/isexplain/status), incremental blob I/O (SqliteBlob), online backup (SqliteBackup + sqlite_backup_run), serialize/ deserialize, and library utilities (complete, strglob/strlike/stricmp, randomness, memory, compileoptions). One variant per duplicate family (modern/64-bit preferred; bind_text/blob keep the 32-bit length forms that skip text64's encoding arg). Not bound, by design: callback-taking APIs (hooks/UDFs/collations need C->sx callbacks), sqlite3_value_* (UDF-coupled), varargs config, UTF-16, and subsystems this build omits — the boundary list lives in the module header and vendor README. rename.h is now GENERATED by make into build/vendor/ from the bindings' #foreign names — src/db/sqlite.sx is the single source of truth and the rename list cannot drift (checked-in vendor/sqlite/rename.h removed). make test 21/21 (new: sqlite_api.sx — 15 cases over every wrapper family, including a blob round trip with interior NULs, UNIQUE constraint extended errcodes, txn_state through BEGIN IMMEDIATE, backup db->db, and a serialize->deserialize round trip). KNOWN sx BOUNDARY (filed as a followup): 'if !e' on an error binding evaluates true even when the error is set — negated error logic in tests routes through plain bools.
