 ### Added
-- **Global realized-loss gate for close orders** - Added `live.max_realized_loss_pct` to block any close order (including WEL/TWEL auto-reduce and unstuck) that would realize losses beyond a peak-balance-relative threshold. Panic closes remain exempt. Live bot now emits `[risk]` warnings when orders are blocked by this gate.
+- **Global realized-loss gate for close orders** - Added `live.max_realized_loss_pct` (default `0.05`) to block any close order (including WEL/TWEL auto-reduce and unstuck) that would realize losses beyond a peak-balance-relative threshold. Panic closes remain exempt. Live bot now emits `[risk]` warnings when orders are blocked by this gate.
 
 ### Fixed
 - **False-positive stale Rust extension after identical rebuild** - `sync_installed_extension_into_src()` now updates the local `src/` `.so` mtime when its content (SHA256) already matches the installed site-packages build. Previously the old mtime was preserved, causing `check_and_maybe_compile` to report the extension as stale in a loop even though the binary was current.

 - **Config template/format preservation** - Added `live.enable_archive_candle_fetch` to the template defaults and ensured `backtest.market_settings_sources` is preserved during config formatting.
 - **Live no-fill minute EMA continuity** - When finalized 1m candles are missing because no trades occurred, live runtime now materializes synthetic zero-candles in memory (not on disk), preventing avoidable `MissingEma` loop errors on illiquid symbols. If real candles arrive later, they overwrite synthetic runtime candles and invalidate EMA cache automatically.
 - **Suite base scenario inherited all scenario coins** - Scenarios without explicit `coins` (e.g. the `"base"` scenario) fell back to `master_coins` — the union of every scenario's coin list — instead of the original `approved_coins` from the config. Now `apply_scenario` falls back to `base_coins` (the config's `approved_coins`) when a scenario omits its own coin list.
-- **Aggregate methods ignored in optimizer scoring and Pareto analysis** - `calc_fitness` always looked up the `_mean` stat for every scoring metric, ignoring the `backtest.aggregate` config (e.g. `"high_exposure_hours_max_long": "max"`). The optimizer now overrides `flat_stats` with correctly aggregated values before computing objectives. The standalone `pareto_store.py` script also reads the aggregate config from each entry and corrects stored objectives via a ratio adjustment, and uses the config when resolving limit filters.

The optimizer now overrides `flat_stats` with correctly aggregated values before computing objectives. The standalone `pareto_store.py` script reads the aggregate config for suite-metric extraction and limit filtering while leaving stored objectives unchanged.
 - **Backtest HLCV cache reuse across configs** - Configs that differ only in trading parameters (EMA spans, warmup ratio) now share the same HLCV cache slot. Previously, different EMA spans produced different `warmup_minutes`, which was included in the cache hash, causing unnecessary re-downloads. The cache now uses a ratchet-up strategy: warmup sufficiency is checked at load time, and the cache is overwritten only when a larger warmup is needed.
 - **Backtest cache warmup downgrade guard** - Cache saves now keep the highest recorded `warmup_minutes` for a cache slot and skip writes that would downgrade it, reducing refetch churn when multiple runs touch the same cache concurrently.
