Deterministic tiers: core = token overlap with top-20 market hard skills or essential ESCO competences; in-tier ranking by overlap score. Per-source cap 10 (overflow -> audit log, not the package). Source-domain allowlists stop cross-contamination (marketing skill entering an engineering package via a generic 'api' keyword). Flagship selection: 427 -> 73 entries; all 10 real v1 flood negatives excluded, 10 must-have positives included.
