WalkthroughThe worker adds persistent protective-stop-unplaced alerts with independent Redis throttling and boot wiring. It updates protective-stop condition identity handling, expands replacement-order notifications, and uses shared terminal-status detection for detached order reconciliation.

Normalize orderStatus before routing FILLED.
Both reachable producers pass the source orderStatus spelling through as a string. When that value is filled, isTerminalOrderStatus accepts it, but the strict comparison selects closeByBinanceOrderId instead of markFilledByBinanceOrderId. The plain close does not merge cumQty or cumQuoteQty into raw, so the detached order keeps incorrect execution totals.
Normalize once for the terminal check and FILLED comparison. Preserve the original status when calling closeByBinanceOrderId.
Proposed fix
- if (!isTerminalOrderStatus(event.orderStatus)) return;
+ const orderStatus = event.orderStatus.toUpperCase();
+ if (!isTerminalOrderStatus(orderStatus)) return;
...
- event.orderStatus === 'FILLED'
+ orderStatus === 'FILLED'
...
- event.orderStatus,
+ event.orderStatus,📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

The existing protective-stop alert is shaped around one cause: the exchange's price band refuses the stop. Every other way a stop fails to reach the exchange produced a condition row the strategy re-reported on every tick and nothing ever escalated, so a position could sit unguarded indefinitely without the operator being told. Add an outcome-shaped alert beside it: whatever the cause, this position is held and nothing is resting that would sell it. It fires off the exit-blocked row carrying the unplaced code, gated on that row's age, so it cannot page about a position that opened moments ago. It fails closed on an undated span, unlike the band alert. That one has an independent span-free signal for a permanent fault; this one does not, and without the age it cannot be told apart from a fresh entry. The row is re-read next tick, so a lost write costs a tick of delay, not the alert. It is suppressed on any tick the band alert already fired, since both describe the same unguarded coin and the band one carries the more specific instruction, and it takes its own throttle key so the two alerts cannot mute each other on exactly the coin where both matter. The band explanation is now parsed before its throttle window opens; a detail it could not parse previously threw after the key was set, losing that alert and muting the next hour of them. Also closes a detached-fill leak: the reconciler's own terminal-status set omitted the self-trade-prevention status, so such a row was never closed and held its live slot and open exposure forever.
