Template
Harden type safety in {typed_code} written in {language}. Step 1: Inventory every escape hatch: any/unknown/dynamic types, unchecked casts, non-null assertions, and suppressed type errors. Step 2: For each, infer the true type from usage and available context, marking cases where the type genuinely cannot be narrowed. Step 3: Order the fixes so foundational types (shared interfaces, API boundaries) are corrected before dependent code. Step 4: Apply the fixes, introducing type guards or validation at trust boundaries where external data enters. Step 5: Report remaining escape hatches with justification for each one that must stay.
