+0000 Subject: [PATCH 2/3] feat: add Phase 3 report generation and CLI integration - Add src/measurement-validator/ module with: - types.ts: shared MeasurementResult, MeasurementSeverity, etc. - stats.ts: computeSummary and computeStatsByLanguage helpers - csv-exporter.ts: RFC 4180 CSV with UTF-8 BOM support - markdown-exporter.ts: GitHub Flavored Markdown with language grouping - html-report-generator.ts: self-contained HTML with filter controls - json-exporter.ts: JSON serialization - report-formatter.ts: ReportFormatter class with filter/sort/export - index.ts: public module exports - Add scripts/cli.ts: entry-point CLI (validate/report/help) - Add scripts/validate-command.ts: validate against corpus - Add scripts/report-command.ts: generate report from saved results - Add test/report-generators.test.ts: CSV/Markdown/HTML/JSON tests - Add test/cli.test.ts: CLI validate/report command tests - Add docs/reports.md and docs/cli-reference.md - Add 'validator' script to package.json Agent-Logs-Url: https://github.com/Himaan1998Y/pretext/sessions/471b2265-b3a3-4234-aa20-a154b7a623f5 Co-authored-by: Himaan1998Y <210527591+Himaan1998Y@users.noreply.github.com> ---
