Add 18 new typed methods to CharacterRepository (ReadTime, SaveTime, SaveInt, SaveBool, SaveString, ReadBool, ReadString, LoadColumnWithDefault, SetDeleted, UpdateDailyCafe, ResetDailyQuests, ReadEtcPoints, ResetCafeTime, UpdateGuildPostChecked, ReadGuildPostChecked, SaveMercenary, UpdateGCPAndPact, FindByRastaID) and migrate ~56 inline SQL queries across 13 handler files. Pure refactor — zero behavior change. Each handler produces identical SQL with identical parameters. Cross-table JOINs and bulk CharacterSaveData operations are intentionally left out of scope.

// Package channelserver implements plate data (transmog) management.
|
|
//
|
|
// Plate Data Overview:
|
|
// - platedata: Main transmog appearance data (~140KB, compressed)
|
|
// - platebox: Plate storage/inventory (~4.8KB, compressed)
|
|
// - platemyset: Equipment set configurations (1920 bytes, uncompressed)
|
|
//
|
|
// Save Strategy:
|
|
// All plate data saves immediately when the client sends save packets.
|
|
// This differs from the main savedata which may use session caching.
|
|
// The logout flow includes a safety check via savePlateDataToDatabase()
|
|
// to ensure no data loss if packets are lost or client disconnects.
|
|
//
|
|
// Cache Management:
|
|
// When plate data is saved, the server's user binary cache (types 2-3)
|
|
// is invalidated to ensure other players see updated appearance immediately.
|
|
// This prevents stale transmog/armor being displayed after zone changes.
|
|
//
|
|
// Thread Safety:
|
|
// All handlers use session-scoped database operations, making them
|
|
// inherently thread-safe as each session is single-threaded.
