Encode Invariant

Turn an accepted rule into a focused guard without creating new product policy.

1. Read The Owners

Read applicable AGENTS.md, docs/WORKFLOW.md, and the complete encoding pattern. Locate the repository's product or technical authority and its native validation owner.

2. Pass The Authority Gate

Cite the accepted source and restate the exact scope, allowed behavior, forbidden behavior, and authorized exceptions. Stop before edits if authority is absent or materially ambiguous.

Do not promote conventions, code patterns, tests, defaults, tool behavior, or undocumented preferences into policy. An existing check without accepted authority is a mismatch to report, not authority to expand.
