+"""Realized-IC circuit breaker TopkDropout strategy.
+
+Subclass of ``qlib.contrib.strategy.signal_strategy.TopkDropoutStrategy`` that
+holds the book (issues NO orders) while the streaming realized RankIC of the
+deployed signal is below threshold — i.e. the model's cross-sectional
+predictions are no longer earning against realized forward returns. When the
+gate is open it behaves exactly like the reference TopkDropoutStrategy.
+
+The gate is evaluated per trade step on the trailing mean realized RankIC of
+the signal over the last ``ic_window`` trading days whose label is fully
+realized as of the decision date (no lookahead — a 5d fwd label ``close[t+6]/
+close[t+1]-1`` is only known at ``t+6``).
+
+Two wiring modes:
+
+* ``ic_gate``: a precomputed ``pd.Series`` indexed by datetime of booleans
+  (True = gate open / trade allowed). Computed once by the caller (e.g.
+  ``rd_backtest``) and looked up per step. Missing dates default to open.
+* realized-IC self-computation: when ``ic_min_rankic`` is given but no
+  ``ic_gate``, the strategy computes the per-date realized RankIC itself from
+  ``self.signal`` (the pred scores) and the lake 1d bars via
+  ``tac_qlib.risk_limits.realized_rankic_series``, then applies the same
+  trailing-window comparison. Works when instantiated from a workflow YAML
+  PortAnaRecord config (``lake_root`` / ``market`` must be provided).

+"""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.

+other days the strategy issues NO orders (holds the book untouched).
+
+The weekly cadence is derived from the qlib trade calendar: a rebalance happens
+when the current trade step's date belongs to a different ISO ``(year, week)``
+than the previous trade step. ``hold_band_pct`` (default 0) optionally skips
+tiny rebalances: when a name's existing position differs from the new target by
