Ports retail's CharGenState as the one Runtime-owned character-creation
state machine, mirroring RuntimeCharacterSelectionState's exact pattern
(snapshot/delta/event-stream, borrow-only view, generation-gated
commands, one mutable owner, no App types). Every command ports a named
retail function: SetHeritageGroup, SetGender, SetTemplate/ApplyTemplate
(Custom = template 0, Olthoi force-lock), the six attribute setters plus
GetAbsRemainingCredits/BalanceAttributes (retail's literal round-robin
order and fairness cursor), SetSkillLevel plus ResetSkillLevels' free-skill
baseline (reusing CC1's ChargenSkillCreditMath two-tier cost lookup
verbatim), RandomizeStartArea, and DoFinish's complete gate sequence
(empty name / unspent attribute credits / already-Pending / client-side
roster-vs-slotCount cap).
LiveSessionController gained a sibling IRuntimeCharacterCreationCommands
implementation, a CreateCharacter wire hook, and a response handler that
reuses existing machinery rather than inventing new paths: the Ok
identity is appended to the roster via RuntimeCharacterSelectionState's
own ApplyRoster, and the "log straight in" behavior reuses the private
EnterSelectedCore. ILiveSessionLifecycleHost gained two default-no-op
hooks (ApplyCharacterCreated/ApplyCreationFailed) so AcDream.App needs
zero changes to keep compiling; wiring them to the status stream is a
CC4 follow-up.
Filed four divergence-register rows for the corners deliberately not
ported: the FPU-unrecoverable FitTemplateToCharacter auto-detect (AP-207,
ACE only reads the field for title text), the per-style color-count
approximation (AP-208, CC1's model has no per-style palette data), the
classID DAT-DID placeholder (AP-209, ACE ignores the field), and
ApplyTemplate's atomic-vs-sequential attribute apply (AP-210).
34 new tests: full state-machine coverage (every Finish gate, every
rejection-code mapping, duplicate-NameInUse tolerance, Olthoi lock,
attribute balance/lock interaction, uncostable-skill rejection) plus a
LiveSessionController integration suite proving the wire send is exactly
55 skill slots (decoded from a real WorldSession + GameMessageCapture)
and the full Ok/rejection round trip through WorldSession.ProcessDatagram.
