description	Model and evolve Laravel data structures safely with integrity, performance, and rollout-aware migrations. Use for eloquent relations tasks.

Eloquent Relations (Laravel)

Use when

• Designing schema/relations or data lifecycle changes.
• Improving query performance and integrity guarantees.

Default workflow

1. Define domain ownership/cardinality and compatibility constraints.
2. Apply additive-safe schema/relationship changes first.
3. Update query loading/index strategy for affected paths.
4. Validate migration/relation behavior and rollback posture.

Guardrails

• Preserve data integrity with constraints and transactions where needed.
• Avoid destructive one-step production migrations.
• Eliminate hidden N+1 in hot paths.

Progressive disclosure

• Start with this file for execution posture and constraints.
• Load references only for deep implementation detail or edge cases.

Output contract

• Schema/model/relation changes.
• Migration sequencing and rollback notes.
• Validation commands and observed outcomes.
