Exception Management — Time-Bound, Tracked Policy Exceptions

[djm81]

Why

Exceptions must stay governed and time-bound even when they target clean-code rules.

What Changes

• Keep exception ownership in the existing governance model.
• Express clean-code exceptions by policy rule ID such as clean-code-principles/banned-generic-public-names.
• Avoid adding a parallel principle field or clean-code-specific exception schema.
