-- AToKioMonad — Bounded Monad with Precondition Gates
-- bridges/haskell/AToKioMonad.hs
--
-- Monadic interface for AToKio that enforces all 7 Phase 7 invariants
-- at each bind (>>=) operation. Every step must pass the invariant gate
-- before the next computation is allowed to proceed.
--
-- This allows Ahmad_bot code to be written in the AToKioM monad,
-- with automatic invariant checking on every monadic operation.
--
-- Example:
--   do
--     frame <- detectFrameM query
--     temp <- quantumMonadM frame
--     result <- executeM temp
--     return result
--
-- Each step is automatically validated before proceeding.
-- If any invariant fails, the monad returns Left with violation details.
