Teaches schema-first design, drizzle-kit migrate vs push, sql template tag for parameterized queries, drizzle-zod validation pairing, Postgres RLS / materialized views / sequences, Testcontainers transaction-rollback tests. Catches Prisma muscle-memory leakage (include/select), removed casing API, deprecated generate:pg, SQL injection via execute concatenation, .returning() on MySQL, missing await on builders, drizzle-kit push in production, and 13 more LLM regressions.
