artifacts.rs:
- Summary struct (total_pnl_usd, sharpe_ann, sortino_ann,
max_drawdown_usd, calmar, n_trades, win_rate, avg_win/avg_loss,
profit_factor, total_fees_usd, exposure_pct,
kelly_cap_history_sample).
- compute_summary(records, pnl_curve_usd) — non-overlapping
annualisation × √825 per pearl_phase1d4_backtest_cost_edge_frontier
(K=6000 holding × 250 trading days ≈ 825 trades/year).
Sharpe + Sortino + max drawdown + Calmar.
- write_summary (JSON pretty-printed), write_trades_csv (with USD
conversion from fp ×100), write_pnl_curve_bin (bytemuck-cast f32
slice). 5 unit tests with tempdir.
aggregate.rs:
- aggregate_sweep_dir walks <root>/<cell>/summary.json, builds an
arrow RecordBatch (cell name + 9 stats columns), writes
SNAPPY-compressed aggregate.parquet.
- pareto_frontier: cells are kept unless another cell weakly
dominates on all three of (sharpe_ann maxed, max_drawdown_usd
minimised, total_fees_usd minimised) AND strictly improves on one.
Written to pareto_frontier.json (Vec<cell-name>).
- 2 unit tests (3-cell mutual-non-dominance; B-dominates-A).
harness.rs:
- run() now samples Pos.realized_pnl × $50/index-pt per event into
self.pnl_curves[b], so the per-cell P&L curve is ready for
write_artifacts() without an extra sim pass.
- write_artifacts(out_dir) — per-cell <out>/cell_NNNN/{summary.json,
trades.csv, pnl_curve.bin}.
bin/fxt-backtest:
- clap-derive CLI with two subcommands:
run --data <dir> [--predecoded-dir <dir>] [--policy-grid <yaml>]
[--n-parallel N] [--decision-stride S] [--latency-ns N]
[--target-annual-vol-units F] [--annualisation-factor F]
[--max-lots N] [--max-events N] [--seed N] --out <dir>
aggregate <sweep_dir>
- Constructs MlDevice::cuda(0) + CfcTrunk::new_random for the trunk
(v1 — ml-alpha has no checkpoint format yet; --seed gates init).
- Parses --policy-grid YAML if given but doesn't yet plumb to the
LobSimCuda decision kernel (the v1 kernel hardcodes the
Strategy::default_for path; bytecode VM is C7's deferred follow-up).
Parse step kept end-to-end so the YAML format is validated now.
- --latency-ns parsed but not consumed — reserved for follow-up
resting-order in-flight promotion (deferred from C5).
Adds parquet + arrow + arrow-array + arrow-schema + serde_yaml to
ml-backtesting deps; bin/fxt-backtest added to workspace members.
All 33 lib tests + 6 GPU fixture tests green. CLI --help renders both
subcommands correctly.
