Decode Project Sylpheed's IDXD data model into plain, cloneable structs (from GP_MAIN_GAME_E.pak; the D/F/I/J/S paks are localized dups): - Weapon (121), CraftUnit (89, with the AI flight model in .fields), Vessel (23, structural component counts), PlayerConfig (24) — the full combat balance. - Character (68 — faction + portrait set), Stage (29 missions: location, phases, and the per-stage resource tables it wires up). - Generic Record / load_records(schema) reads any of the 105 IDXD schemas without a bespoke struct. Each blob = one entity; token[0] names the table, fields are value-before-key. Named Option<> fields for the common stats + a full `fields` map; defaulted fields stay None (they're code-resident, not on disc — honest blanks, never guessed). 8 tests against the real disc. Examples: iso_map / deep_map census the ISO's formats and IDXD schemas; dm_extract / dm_rows / dm_roster / mission_map dump the decoded data. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
