Request: - Use the project archivist workflow to update historical IPO data. Changes: - Add an embedded SQLite archive at data/hk_ipo.sqlite. - Add schema/hk_ipo.schema.sql and scripts/bootstrap_historical_data.py for reproducible archive generation. - Archive HKEXnews source PDFs for 06658, 06675, and 06106 under repo-relative data/raw paths. - Export Git-friendly snapshots for ipo_master, offering_terms, ipo_demand, source_refs, and data_gaps. - Add .gitignore rules for Python cache and SQLite transient files. Verification: - Re-ran the bootstrap script successfully. - Ran PRAGMA integrity_check on the SQLite database. - Verified source_refs paths are repo-relative, files exist, and SHA-256 hashes match. - Verified snapshot row counts match SQLite table counts. - Ran git diff --check and searched generated durable files for machine-specific absolute paths.
