The first live UCITS paper run on bizworx reported EXECUTED/exit-0 but was
degraded: the IEF->CBU0 leg got 0 fills and DBMF hung Submitted.
- Error 478 (contract conflict): the ISIN-qualified UCITS contract kept a
localSymbol/secId conflicting with the pinned conId (requested CBU0 vs
canonical CSBGU0). Strip secId/secIdType/localSymbol after resolve and route
by conId + SMART.
- Error 10349 (TIF preset): the bare MarketOrder had no TIF so the account
preset forced DAY + cancel/reconfirm. Set explicit tif="DAY".
- False-success (the dangerous one): plan.executed counted Cancelled/Submitted
legs as placed, and exec-record booked on any non-blocked run. Now executed
requires EVERY leg filled; a degraded run prints DEGRADED, exits 1, and
skips exec-track booking so the reconciliation gate stays WAIT (never books a
phantom rebalance) — real money errs false-WAIT.
Tests: new test_ucits_exec_fill_status.py + degraded cases in test_execution.py
and test_execute_multistrat_b2a.py (TDD failing-first). 523 exec/forward/gate
tests green, mypy clean.
