Add full file-format wiki: home status table + per-file detail pages Documents every file on the CD_8555 map disc (db/ folder): byte layouts, decode status (cracked/partially cracked/not examined), and validation evidence for each, distilled from the main repo's README research log. Covers the road graph (eeu.rd/.il/.iof/.typ), the road/city name-search catalogs (rt/rl/prl, cty/cl/ct, ctr), the MAP_COMPRESSED tile format (mp0/mg1-mg4) including tile geometry and the topology/adjacency table, the eeuz.fea gazetteer, the FLAT_COMPRESSED container, ISO handling, and a first-look triage of the 16 files never examined at all. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
