 ## Requirements-first TDD
 
 - Write requirements as desired behavior, not as a snapshot of current behavior.
-- Keep each requirement row to one checkable obligation; shorten near-limit rows or split oversized examples, escape hatches, or negative cases into separate stable IDs while preserving the original ID's main intent.
+- Keep each requirement row to one checkable obligation with an explicit redgate ring field; shorten near-limit rows or split oversized examples, escape hatches, or negative cases into separate stable IDs while preserving the original ID's main intent.
 - First split intent into broad error classes: what can go wrong, and what outcome must hold.
 - Test the largest risky classes before narrow examples.
 - Add adversarial tests for malformed, hostile, ambiguous, missing, duplicated, and boundary inputs.
