Test doesn't exercise the actual int64-max boundary or overflow protection.
The updated assertions only prove values beyond the old int32 limit are now accepted; they don't cover the new overflow-safe subtraction check (current <= maxUserQuotaValue-delta) near the real maxUserQuotaValue boundary, which is the actual correctness improvement in isValidQuotaAddition.

🧹 Nitpick | 🔵 Trivial
Raw-SQL pre-migration for a large users table can be slow/locking.
MODIFY COLUMN/ALTER COLUMN TYPE on a large users table can hold a table-level lock for a noticeable duration on MySQL/Postgres during startup migration, delaying app boot. Worth noting for operators with large user tables (consider off-peak deploys or an online-DDL tool for very large tables).

GORM v2 default tag MySQL AutoMigrate nullable NOT NULL integer field behavior
💡 Result:
In GORM v2, AutoMigrate handles integer field nullable/NOT NULL constraints based on the Go struct type definition and GORM tags [1][2][3]. 1. Field Nullability: By default, Go primitive types (e.g., int, int64) are treated as non-nullable [3]. To make an integer field nullable, use a pointer type (e.g., *int) or sql.NullInt64 [4][5][3]. 2. NOT NULL Constraint: Use the gorm:"not null" tag to explicitly enforce the NOT NULL constraint [6][3]. 3. AutoMigrate Behavior: - GORM v2's AutoMigrate will automatically add or remove the NOT NULL constraint if you change the tag in your Go struct [1][2]. - If you change a column from non-nullable to nullable, GORM will typically issue an ALTER TABLE statement [1][6]. - If you change a column from nullable to non-nullable, the migration may fail if the database already contains NULL values in that column [6]. - Note that AutoMigrate logic for constraints has historically had complexities; GORM specifically checks for tag settings and compares them against existing database schema metadata [7]. 4. Default Tag: Using gorm:"default:..." defines the database-level default value [3]. Be cautious with gorm:"default:null", as it has been reported in some versions/dialects to cause unexpected behavior like repeated table recreations or issues with value handling during persistence [8][9]. For robust handling of nullable integer fields, using pointer types or sql.NullInt64 is the recommended approach to ensure GORM correctly maps the field to a database-level NULL [4][5][3].

Preserve the existing NOT NULL constraint in the MySQL migration. ALTER TABLE ... MODIFY COLUMN ... bigint DEFAULT 0 restates only the type/default, so MySQL can drop NOT NULL and any other omitted attributes. Use bigint NOT NULL DEFAULT 0 here.

Use int64 for the quota fields backed by bigint. Quota, UsedQuota, AffQuota, and AffHistoryQuota are still int, so the model only carries the full bigint range on 64-bit builds. If these values need to exceed 32-bit limits, widen the user quota path together, including the quota validation helpers in controller/user.go.
