weapons physics audit (7-agent, all classes): docs/WEAPONS_FIELD_GUIDE.txt (tester-facing per-weapon review doc for the playtest group) + docs/WEAPONS_DRIFT_AUDIT.md (engineering drift table with addresses/tiers). Headline corrections the audit itself produced: (1) GAUSS RETRACTION -- the fielded GAUSS record is classID 0xBCD ProjectileWeapon (BTL4.RES @0xf16e6 raw bytes), full AC hitscan WITH damage; GaussRifle 0xBCE + shell 0xBD1 are dead code BOTH sides (zero shipped records; content census 78x0xBC8/16x0xBCD/30x0xBD0/14x0xBD4); the 'port Gauss damage is an invention' claim retracted in KB + ticket. (2) effectiveRange K byte-confirmed 1.0f @004b9c98. (3) PPC EnergyDamage victim-side GAUGE SCRAMBLE rider identified (@004a0230 -> gauge renderer) -- unimplemented in port, and it is exactly what Cyd's held ppc-sync-distortion branch implements: that branch is an AUTHENTIC-feature candidate, not an invention. (4) AC tracer TOF constants recovered (2.0f @0x4bc678, 1/9.8 x87 EXTENDED @0x4bc67c) -- port's 1.0 stand-ins closable. (5) missiles verified FAITHFUL end-to-end (382-impact corpus matches the salvo roll).

commit-hygiene sweep: (1) the #170 L4STEAMNET.h contract comment never landed in 2fe58b8 -- the git add used the lowercase filename and the case-mismatch left the tracked (uppercase) path unstaged, silently; (2) the gauges-hud #172 correction was a silent no-op -- a python str.replace whose multi-line needle didn't match printed 'corrected' anyway.

#174 root-caused + fixed with a negative control: the binary's ONLY re-descend protection is the burst loop's zone-state guard wrapping the WHOLE per-burst application (@0x4a0446, part_012.c:14661 -- crit roll, TakeDamage, score tally, destroyed-flag; RecurseSegmentTable/SendSubsystemDamage have NO internal re-entry protection: no used-marking, no top gate). The port had narrowed the guard to the crit roll -- continued fire re-saturated dead zones (cascade re-fired: night-16 zone 18 x7, each pass re-pushing crit allotment = the ram 'crits worsened with each collision'), and hits on wreckage kept SCORING (binary awards zero -- a quiet farm-the-wreck exploit). Fix: guard restored to binary scope. Bench: BT_ZONE_HAMMER hook (4Hz explicit-zone self-damage) -- fixed build 1 cascade/10 hits/0 post-saturation applications; NEGATIVE CONTROL (fix stashed): 147 cascades. 147 -> 1. Gotcha 31: guard-scope narrowing -- diff the BRACE SCOPE when transcribing decomp ifs; and prove a bench detects the bug before trusting its pass

#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.

#165 ROOT-CAUSED after three failed fixes -- the binary keeps ONE destroyed cell per subsystem (+0x40: fire gate, dial X, wire header, every writer) and the port split it into FOUR stores; the everyday CRIT-LOTTERY kill (MechWeapon::TakeDamage) bypassed the reconstructed base and wrote only the X store, so X'd weapons kept firing while every prior fix aimed at a gate that was never broken (the 4,213-refusal bench drove BT_KILL_SUBSYS, which writes all cells -- it validated readers, not writers). FIX: MechWeapon::TakeDamage chains to MechSubsystem::TakeDamage (@0x4ac0bc semantics); the port-authored FSM-from-damage tail is DELETED (it parked partial-crit weapons at level 1 -- no FSM case, the silent freeze, and with beamFlag armed the 883 hanging beam: #164's upstream writer, caught red-handed by berserker's 20x STUCK-ON receipts); the phantom uninitialized simulationState int is ctor-initialized and kept in lockstep at every destroyed write; always-on [crit] DESTROYED receipt makes crit kills field-visible. BT_CRIT_SUBSYS bench hook drives the REAL writer path; weaponx_bench PASS: kill phase 0 FIRED post / 5,664 refusals / X+gate agree, partial phase keeps firing. Gotcha 30; #174 filed (cascade re-descend)
