Symfony Voters (Symfony)

Use when

• Hardening access-control or validation boundaries.
• Aligning voters/security expressions with domain rules.

Default workflow

1. Map actor/resource/action decision matrix.
2. Implement voter/constraint logic at the right boundary.
3. Wire checks at controllers and API operations.
4. Test allowed/forbidden/invalid paths comprehensively.

Guardrails

• Avoid policy logic duplication across layers.
• Do not leak privileged state via error detail.
• Preserve explicit deny behavior for sensitive actions.

Progressive disclosure

• Use this file for execution posture and risk controls.
• Open references when deep implementation details are needed.

Output contract

• Security boundary updates.
• Integration points enforcing decisions.
• Negative-path test results.
