-# ── Migrations ─────────────────────────────────────────────────────────
-# Reverted 2026-07-31: excluding new EF Core migrations while
-# ErpDbContextModelSnapshot.cs stayed tracked meant every `dotnet ef
-# migrations add` after the initial 4 silently produced a migration git would
-# never see, while the (tracked) snapshot's changes committed normally —
-# so the snapshot kept claiming tables existed that no migration in git
-# history ever created them. Confirmed live: 25 HRM tables + 11 Manufacturing
-# tables were missing from the actual database for exactly this reason.
-# Migrations now stay tracked like any other source file — commit them.
