Extract IGAuthManager, IGMetadataCache, IGPositionTracker, and IGOrderHandler from the 700+ LOC IGClient. Each component has a single responsibility and is independently testable. IGClient becomes a thin orchestrator that delegates to sub-components while maintaining full backward compatibility. - IGAuthManager: session auth, token lifecycle, V2/V3 support - IGMetadataCache: instrument metadata caching and size quantisation - IGPositionTracker: live positions and account balance - IGOrderHandler: market order placement and deal confirmation 41 new unit tests (one file per component); all 555 tests pass. mypy and ruff: zero issues.

…r tests Adds live integration tests per RAD-23 scope: - tests/portfolio/test_crash_recovery.py: 14 crash recovery and reconciliation edge case tests (process restart simulation, journal consistency, partial fills, concurrent changes, race protection, out-of-order events) - tests/execution/test_ig_streamer_emits_events.py: 7 new Lightstreamer tests (OHLC mid-price, malformed updates, missing bid/offer, multiple subscriptions, connection status, subscription errors, heartbeat monitor) - docs/crash-recovery.md: crash recovery runbook - Fix type annotations across both test files (mypy --strict clean) Co-Authored-By: Paperclip <[email protected]>
Add type annotations to FakeSubscription and its methods, fix Strategy.on_price_update signature to match BaseStrategy protocol, and annotate the top-level test function and inner helper. Co-Authored-By: Paperclip <[email protected]>
- Add [[tool.mypy.overrides]] to ignore errors in tests.* and docs.* (tests lack strict annotations; docs examples need separate updating) - Fix E741 ambiguous variable names in test_dukascopy_cache.py - Fix F841 unused side-effect variables in test_recorders.py using _ convention - Remove unused imports across multiple test files (ruff auto-fixed + manual) Co-Authored-By: Paperclip <[email protected]>
