Raw SQL timestamp expressions can bypass ORM Date encoding

When an ORM update mixes mapped timestamp assignments with a raw SQL expression, do not assume interpolated JavaScript Date values receive the column's timestamp encoder. A delivery callback can pass authentication yet fail before its status update reaches the database. Investigate the nested driver cause, inspect the expression boundary, and verify the actual parameter encoding before choosing a fix. Applicability: Drizzle/postgres.js code mixing raw SQL interpolation and Date inputs. Limits: this observation does not show that every raw SQL timestamp expression fails, and no corrective implementation or live replay was tested.
