1. hyperliquid.open_position now returns effective_leverage. HL clips the requested leverage to each asset's max (e.g. memes capped at 3×) and silently applied the lower value; we were discarding that. For System-2 this meant sys2_protective_stop_pct was computed against the REQUESTED leverage, so the "inside-liquidation" full-close rung was actually well inside an 8.5% stop while the real liquidation sat ~33% away — strategy intent broken. bot_engine now reads the effective value back, recomputes the protective stop + derisk ladder against it, and freezes the correct values into BotTrade.eff_* / .leverage. 2. circuit_breaker.clear_trip now clears BOTH systems by default. The sys2 column was never reachable from any reset path — a sys2 trip forced users to wait the full 24h lockout even after explicit human re-arm. 3. /api/user/.../manual-window and /auto-trade re-arm endpoints now clear sys1 AND sys2 CB on the same human ack. Symmetry with check_and_trip / is_tripped which already supported both systems. 4. telegram.py deep-link map: btc_bottom_reversal + funding_reversal alerts now point at /en/macro instead of the now-404 /en/btc. 5. (Already landed: _sys2_mode UnboundLocalError fix in bot_engine — restated here for the audit trail.) Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
