Probe (probe-ucits-symbols, live 2026-07-20) confirmed only the IEF line diverges: config ticker CBU0 resolves to IBKR canonical symbol CSBGU0, which is what positions() reports the holding under. _expected_book_symbols keyed on the display ticker, so the legitimate 55-share IEF/Treasury book position (reported CSBGU0) was flagged 'outside the book' and dropped from NLV. Add UcitsListing.ibkr_symbol (defaults to ticker; set CSBGU0 for IEF) and include it in _expected_book_symbols so the stray-check matches what IBKR actually reports. A genuine stray (IBIT) is still flagged. Also fixed 4 lint items on the touched lines. 11 dashboard tests green (new CSBGU0-not-stray test + IBIT-still-stray + no regression).

fxhnt
Agentic strategy-research & multi-strategy execution platform. It systematically discovers, backtests and out-of-sample-validates trading strategies across many markets, keeps only what survives a rigorous statistical gauntlet, and runs the survivors live (multiple strategies at once).
The bet is not a secret edge — it's breadth + discipline + automation. The hard part (and the moat) is refusing to fool yourself at scale; the validation gauntlet is the core, built and proven first.
Architecture (hexagonal / ports-and-adapters)
src/fxhnt/
domain/ pure logic: gauntlet (Deflated Sharpe), strategies, backtest, models ← no I/O
ports/ contracts: DataProvider, repositories (the only seams)
adapters/ infra: yahoo data, SQLAlchemy (Postgres/SQLite) + DuckDB stores
application/ use-case services (ResearchService) — orchestrate via ports
cli.py composition root (wires concrete adapters)
See docs/architecture/0001-architecture.md.
Quickstart
pip install -e ".[dev]"
pytest # unit (gauntlet falsification) + integration (vertical slice)
fxhnt strategies # list strategy kinds
fxhnt research SPY --kind trend --window 200 # data → backtest → gauntlet → persist
fxhnt list --passed-only # the survivor library
Config via FXHNT_* env vars (e.g. FXHNT_OPERATIONAL_DSN=postgresql+psycopg://...). Defaults to
SQLite + a local DuckDB file under ~/.fxhnt/.
Status
Vertical slice working: data (Yahoo) → strategy (trend) → backtest (net of costs) → IS/OOS gauntlet → persistence (operational + analytical). Next: the multi-strategy execution layer, more strategy templates + data adapters, and the agentic discovery search on top of the proven gauntlet.
