Why: The approved contract requires exactly three safe attempts for Cursor, agy, and PI, then one Codex emergency attempt, never host implementation authority.
Evidence: Routing/config tests were RED for never, max attempts, forbidden adapters, and legacy host fallback; 133 related tests now pass with one opt-in probe skipped.
Impact: Normal emergency-mode roles reject all non-Cursor/agy/PI adapters, project fallback is never, and Codex remains available through emergency/review paths.
