Deterministic SQLite Variable Limit Across Development Machines

The goal is to guarantee that a prepared statement binding many parameters (e.g., a large IN list) succeeds or fails identically on every developer workstation, preventing the “too many SQL variables” error that appears only on builds with the older default limit.
SQLite’s SQLITE_MAX_VARIABLE_NUMBER default changed from 999 to 32766 starting with version 3.32.0, but custom or OS‑provided builds may still compile with the lower limit, and the effective cap can be queried at runtime. This creates uncertainty about whether to vendor a specific SQLite version to pin the limit and related defaults, or to rely on the system sqlite3 and accept possible drift.
Should we pin SQLite via a vendored amalgamation or versioned dependency to ensure a deterministic 32766 limit? What are the maintenance trade‑offs of upgrading a pinned version versus accepting OS‑provided builds? How can we verify the effective limit at runtime without assuming a particular default?
