v4.5.90 - Agent safety, priority fills, and CCXT normalization - #1161
Conversation
Stop silent zero-trade crypto backtests when strategies use pair-string bases such as BTC-USD/BTC-USD/USD. Resolve to CCXT unified BTC/USD and raise a clear market-missing diagnostic when aliases still fail.

Preserve the requested quote asset during normalization.
When a request is for BTC/USDT and only BTC/USD exists, the resolver currently falls back to BTC/USD. This can fetch USD candles while treating them as USDT data and can submit an order for a different quote asset. Restrict aliases to syntax-equivalent forms such as BTC-USD and BTC/USD; when the requested quote is unavailable, return no match and raise the missing-market diagnostic. Add a regression test for a BTC/USDT request with only BTC/USD available.

Long on_trading_iteration scans (e.g. Titus CVNA ~122s) previously gated fill callbacks and hedge submission until the scan finished. Live mode now drains priority fill/cancel events while the user scan runs, wakes check_queue immediately on those events, and no longer holds fills during sync_broker.

In `@lumibot/brokers/broker.py`:
- Around line 3120-3124: Update the sync and fill coordination around
should_hold_trade_event_for_sync, sync_positions, and _process_filled_order so
stale snapshot reconciliation cannot prune a position created by a priority
fill. Add a synchronization boundary or event-generation validation before
stale-position removal, preserving correct snapshot/event ordering. Add an
interleaving regression test covering sync reconciliation concurrent with a
priority fill.
In `@lumibot/strategies/strategy_executor.py`:
- Line 1371: Update process_queue so concurrent consumers cannot block after
another consumer drains the queue: replace the empty-check plus blocking get
sequence with non-blocking retrieval using get_nowait and handle Empty to end
draining, or serialize the entire drain operation. Preserve processing of all
currently available queue events and ensure check_queue remains safe when
invoking process_queue concurrently.
- Around line 857-858: Implement actual priority scheduling in
StrategyExecutor.add_event() and process_queue(), using a separate priority
queue or draining _PRIORITY_TRADE_EVENTS before normal FIFO events so fills,
partial fills, cancellations, and errors are not delayed by slow new callbacks;
add a backlog regression test. In docs/FAST_ORDER_LIFECYCLE_GUIDE.md lines
75-78, document the current limitation until priority ordering is implemented.
In `@tests/test_priority_fill_during_iteration.py`:
- Line 3: Update the regression comment in the test to remove the private
strategy-owner identity, replacing “Titus / CVNA” with a neutral description of
the live option-fill hedge delay while preserving the date and regression
context.

Implement priority scheduling before promising priority delivery.
StrategyExecutor.add_event() puts all events into FIFO self.queue, and process_queue() handles them in that order. _queue_wakeup.set() only wakes a consumer. A slow new callback can therefore delay a later fill, partial fill, cancellation, or error event. Use a separate priority queue or drain priority events before normal events, and add a backlog regression test. Update docs/FAST_ORDER_LIFECYCLE_GUIDE.md to state this limitation until priority ordering exists.

What
This release preserves the managed-agent gateway and compact account-context work while hardening option-close validation, stock sizing, broker snapshot reconciliation, priority fill delivery, crypto quote normalization, shared-account fill ownership, evaluation fixtures, and wheel contents.
Why
The release fixes the no-trade/tool-loop incident path and safety defects found during release review: duplicate close legs could over-close a position, stale position snapshots could prune a concurrent fill, priority fills could wait behind normal backlog, zero or unavailable stock sizing could still reach order guidance, Coinbase aliases could change the requested quote asset, and foreign broker activity on shared accounts could reach another strategy's fill handler and trigger an unintended hedge.
Risk
Trading-runtime and broker reconciliation behavior changes. Shared-account ownership filtering is live-only so historical backtests retain reconstructed fill callbacks. Detection is covered by unit, backtest, acceptance, real-model, package-integrity, CodeQL, and public-hygiene gates. The release is not merged or tagged until every mandatory gate is green.
