- REQ-017: LedgerPort contract (application/ledger_port.py) + portfolio-hub
  adapter + in-memory stub (adapters/ledger/), TREX_PORTFOLIO_HUB_* config
- REQ-018: fill→ledger recording in execution loop; FillStatus carries
  execution_id (deterministic synth) + fee; paper/kis adapters updated
- REQ-019: ledger outbox + retry worker (application/ledger_outbox.py),
  correlation_id idempotency, outcome vocabulary; 002_create_ledger_outbox.sql
- Tests: in-memory/portfolio-hub ledger, execution ledger hook, outbox,
  domain import sweep
