- GET /api/logbook/progress-map: one compact document, cached until an input changes (main's HEAD, the Logbook symbol table and statistics, match/emulator/library results, facts, names, source files, globals, deferral notes); ?have=<version> answers {"same": true}
- definitions follow the Logbook's progress.py (pc102.csv category game, status decompiled or later), so the headline equals game_bytes_decompiled_percent; engine, library and unsorted code are shown but not counted
- history points now record the commit and the game-code bytes
- the page lays out once per load, filter or size change, hit-tests hover on the computed rectangles, builds the 600-entry units list only when opened, and polls once a minute only while the Logbook is visible
