StrataGUARD

Hard-rule risk gate. Blocks actions that violate explicit risk constraints. Rules are regime-aware and asset-aware. GUARD is never learned — always auditable.

StrataGUARD(asset=None)

from strata import StrataGUARD

guard = StrataGUARD(asset="TSLA")   # HIGH vol profile: relaxed min_abs_bias
guard = StrataGUARD(asset="SPY")    # LOW vol ETF: relaxed max_trap_risk
guard = StrataGUARD()               # no asset profile — regime defaults only

Supported asset profiles: AAPL, TSLA, SPY, NVDA, QQQ

guard.evaluate(state, decision, confidence) → (bool, str)

approved, reason = guard.evaluate(state, decision, decision["confidence"])
# (True,  "OK")
# (False, "TRAP_RISK_HIGH (0.67 > 0.60 [RANGING])")
# (False, "LOW_CONFIDENCE (0.21 < 0.35)")
# (False, "WEAK_BIAS (0.08 < 0.15 [TRENDING])")

Guard Rules

Rules are evaluated in order. First failing rule returns (False, reason).

Rule	Condition	Description
MIN_CONFIDENCE	confidence < threshold	Reject low-confidence signals
MAX_TRAP_RISK	trap_risk > threshold	Block when trap risk is elevated
MIN_ABS_BIAS	abs(bias) < threshold	Require directional conviction
MAX_UNCERTAINTY	uncertainty > threshold	Block in highly ambiguous conditions

All thresholds are regime-dependent and optionally adjusted by asset volatility profile.
