P2: specify validation metrics reporting format in Annex A Week 7 deliverables

[yohei1126]

Context

The submission commits to Precision@50 but does not pre-agree the format or definition of other evaluation metrics (Recall, AUROC, computational cost units, granularity, explainability) with Cap Vista.

Required

Add a "Validation & Reporting" subsection to Annex A Week 7 deliverables with a pre-agreed metrics table:

Metric	Target	Unit	Definition
Precision@50	≥ 0.60	Fraction	Top-50 ranked candidates that are OFAC-listed
Recall@200	≥ 0.40	Fraction	Fraction of all OFAC-listed vessels in dataset captured in top-200
AUROC	≥ 0.80	0–1	Area under ROC curve across all scored vessels
Computational cost	≤ SGD 250/month	SGD	Cloud + storage for continuous 15-min re-scoring at PoC scale
Granularity	Per-MMSI + per-feature	—	Every prediction tied to a MMSI; top-3 SHAP signals per vessel
Explainability	SHAP + ATT + path	Qualitative	Top-3 SHAP attributions, DiD ATT ± 95% CI, ownership graph path per watchlist entry

Acceptance criteria

• Annex A Week 7 deliverables section includes the metrics table above (or equivalent agreed with Cap Vista)
