BTPlayer's master ctor now seeds the flag block from btMission->ExperienceLevel() + AdvancedDamageOn() (accessors from the SURVIVED 1995 BTMSSN.HPP [T0]) instead of the NULL-stubbed scenario role -- the egg experience knob works for the first time. Both switch slot errors fixed vs the binary @4c0bc8; phantom btMission duplicate member removed (+0x1f8 IS Player::playerMission). SEVEN gate stubs unified onto the real flags (two found empirically): HeatModelActive, OwnerAdvancedDamage, LiveFireEnabled, ControlsAllowLights, powersub @4b0efc, emitter's file-local FUN_004ad7d4 + FUN_004ac9c8 stubs. FUN_004ac9c8 family swept (incl. a live raw-offset databinding trap in MechSubsystem::IsDamaged). Flag block renamed to its true semantics (simLive/heatModelOn/...), scoring-era names kept as comments. Includes the #5 [aud-tail] diag in emitter.cpp. ALL 19 shipped eggs say experience=expert -> default behavior UNCHANGED (per-tier verified: novice/standard = no heat/jams, authentic; veteran/ expert = today's exact behavior). Real delta: egg advancedDamage=1 now reaches player+0x264/0x268 (was hardwired 0). Follow-up flagged: the glass FE defaults empty experience to veteran (one tier below shipped). Awaiting human verification. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
