-"""Regime-gate TopkDropout strategy.
-
-Subclass of ``qlib.contrib.strategy.signal_strategy.TopkDropoutStrategy`` that
-holds the book (issues NO orders) while a regime detector says the market is in
-an unfavorable state.  When the gate is open it behaves exactly like the
-reference TopkDropoutStrategy.
-
-Three detector types are supported (all causal — no lookahead):
-
-* ``dispersion``: cross-sectional standard deviation of 22-day rolling returns
-  across the universe.  Gate closes when CS dispersion < threshold (low
-  dispersion means the spread between winners and losers is too narrow for
-  TopkDropout to exploit).
-* ``vol``: cross-sectional mean of 22-day rolling realized volatility.  Gate
-  closes when avg vol is outside a band ``[vol_low, vol_high]`` (strategy
-  needs moderate vol — too calm or too turbulent both hurt).
-* ``hmm``: pre-computed HMM posterior for regime 1 (``sp_hmm_p_regime1``).
-  Gate closes when posterior < threshold (model is not confident the calm
-  regime is active).
-
-The gate is provided as a precomputed ``pd.Series`` of booleans indexed by
-datetime (True = trade allowed).  The companion ``compute_regime_gate``
-function builds this series from lake bars; call it once before backtesting
-and pass the result as the ``regime_gate`` parameter.
