Add smart sampling: distribution extraction, PII masking, and product…#1
Conversation
…ion-like generation Smart Sampling (seedkit sample + seedkit generate --subset): - Extract statistical distributions from production databases (categorical frequencies, numeric min/max/mean/stddev, FK ratios) - PII masking: auto-detect and remove PII column distributions (email, phone, SSN, password, etc.) before saving profiles - Distribution-aware generation: Categorical weighted random, Numeric Box-Muller normal distribution clamped to bounds - Ratio-adjusted row counts: child tables scale proportionally to parent tables based on production ratios - Profile save/load (seedkit.distributions.json) CLI Changes: - New `seedkit sample` command with --tables, --categorical-limit, --min-rows, --output options - New `--subset <path>` flag on `seedkit generate` to use profiles Engine: - GenerationStrategy::Distribution variant with Categorical/Numeric arms - Box-Muller transform for normally-distributed numeric values - Distribution profiles integrate into GenerationPlan::build() Version bump to 1.2.0. 221 tests passing (201 unit + 20 integration).
