KB: EXPERIENCE LEVELS decoded -- the 0x25c block is the simulation-mode flags

Browse Source 
The egg's per-pilot 'experience' (novice/standard/veteran/expert) is the
pod's simulation-fidelity tier -- stored at BTMission+0xe4 and seeded into
the BTPlayer ctor's flag block @4c0bc8 [T1].  The old 'per-role display
toggles / returnFromDeath' reading was WRONG: the source is
mission->experienceLevel, and the neighboring pair copies
mission->advancedDamageOn (the egg's technician splash/collision switch),
not role floats.  Known consumers: 0x260 = the HEAT-MODEL master switch
(FUN_004ad7d4), 0x25c = the novice sim-lockout (jams/searchlight/powersub),
0x274 = the raw level (FUN_004ac9c8 ==0 novice predicate).

NEW established topic context/experience-levels.md (data path, binary flag
rows per level, manual cross-refs, corrections log) + router row; sweeps in
decomp-reference/gauges-hud/open-questions/pod-hardware/subsystems.
btplayer.cpp/.hpp re-annotated with the corrected semantics; the guarded
role-based seeding stays as a marked [T3] stand-in (slot drift vs the
binary switch documented inline) until the wiring task points it at
BTMission::ExperienceLevel().

(Research by the parallel context session; committed from the glass line.)
