Joe DiPrima b94636b607 velocity/dt audit: DRAG WAS THE GOVERNOR -- the binary applies -0.001*v^2 every frame, burn AND coast (@004bef78 + thruster @004be474, ctor precomputes terminal sqrt(T/COD) into +0x348 as the seeker lead base; authored COD 0.001 byte-read from BTL4.RES type-15 srm/lrm/strk/nrk).

#170 root-caused + fixed: the #163 SteamAPI_Shutdown was the crash -- at round end every peer's close events are ALWAYS in flight, and Shutdown tears client state down while steamclient's own service thread dispatches them (the field stack: a steamclient worker calling literal NULL, zero btl4 frames, 7 hits / 3 machines / one module-relative stack). BTSteamNet_ShutdownAll is now a QUIESCE: steamActive gated FIRST, linger closes ('round over' not timeouts), one SNS drain, 60ms grace, NO SteamAPI_Shutdown -- and every exit path dies via TerminateProcess (menu-quit no longer returns through the CRT; it uses BTOrderlyDie like everything else, so the 883 detach deadlock stays dead too). Status callback guarded for the dying window. Crash filter now names foreign DLL frames (module+offset via VirtualQuery/GetModuleFileName) so the next foreign-thread crash arrives pre-symbolized. Exit contract: steam-networking.md

btl4main.cpp

one night = ONE log file: the 8MB size roll-over retired (it cost field evidence the moment it existed -- night16: Elengil's incident window sat in an unsent pre-rotation part; testers attach 'the log' = the newest part). The 6am log-day boundary stays. Transport moves to players/SENDLOGS.bat (ships at the dist root): one double-click zips every log/matchlog/lastrun from the last 36h to a Desktop BTLOGS_<machine>_<date>.zip (~10:1 text compression -- a 13MB night = 1.8MB, well under Discord's 10MB free cap, which is what the roll-over was protecting against). Handout HOW TO REPORT updated; mkdist carries the bat
