-## ✅ COMPLETED
+## ✅ COMPLETED THIS SESSION
 
-### Memory Leaks
-- [x] AutoMessageManager: save task reference, cancel in `stop()`
-- [x] Event listeners: `HandlerList.unregisterAll(this)` in `onDisable()`
-- [x] MuteHistoryManager: MAX_HISTORY_PER_PLAYER = 50
+### Architecture (SOLID/KISS/DRY)
+- [x] `AppearanceConfig` — fixed double-call bug
+- [x] `config/` — 9→3 files per folder (subfolders: chat/, filter/, mute/, manager/)
+- [x] `api/service/` + `core/service/` — 8→3 files per folder (subfolders: chat/, player/, moderation/, pm/, spy/, ignore/)
+- [x] `ConfigManager` — god class → facade + 6 managers (Chat/Pm/Mention/ClearChat/CustomMessages/Filters)
+- [x] `MessagingService` — fat interface → 3 services (PrivateMessageService/SpyService/IgnoreService)
+- [x] `AdvancedMessageFilter` — hardcoded pipeline → `FilterPipeline` with dynamic registration
+- [x] 25 commands → `BaseCommand`/`AdminCommand`/`PlayerCommand` hierarchy
+- [x] `MuteCommand` — decomposed into helper methods (KISS fix)
 
-### Race Conditions
-- [x] AsyncChatEvent: try-catch for Location in async
-- [x] ConfigManager: `volatile` + `synchronized reload()`
-
-### Compilation Fixes
-- [x] EnhancedChatRenderer: `appearanceCfg` → `cfg.getAppearanceConfig()`
-- [x] Replace deprecated `Registry.SOUNDS.match()` with `Registry.SOUNDS.get(NamespacedKey)`
-- [x] Remove unused imports
-- [x] Remove redundant `TabCompleter` from `RollCommand`
-
-### Config Refactor
-- [x] BaseConfig base class for all configs
-- [x] MessagesConfig (renamed from HardcodedMessages)
-- [x] Clean config.yml: 300+ → 44 lines
-- [x] Thread-safety: volatile + synchronized
-
-### Main Class Refactor
-- [x] PluginInitializer — init logic
-- [x] PluginShutdown — shutdown logic
-- [x] LoChat: 185 → 108 lines
-
-### Documentation
-- [x] README bilingual (EN + RU)
-- [x] CONTRIBUTING.md created
-- [x] CODE_OF_CONDUCT.md bilingual
-- [x] SECURITY.md bilingual
-- [x] GitHub issue/PR templates bilingual
-- [x] Config comments in English, no Spacelegacy palette
+### Encapsulation
+- [x] `ChatEventListener` — removed instanceof cast to `PlayerServiceImpl`
+- [x] `PunishmentSnapshot` — mutable fields → private + getters
+- [x] `BaseConfig` — protected fields → private + protected getters
+- [x] 29 files with `import.*` → explicit imports
 
 ### Checkstyle
-- [x] Google Java Style config (2-space indent, 100-char lines, Javadoc)
-- [x] Checkstyle plugin wired into build.gradle.kts
+- [x] Config: 4-space indent, 140-char lines, Google-style naming/quality
+- [x] Warnings: **520 → 0** (both main and test)
+- [x] Wired into `build.gradle.kts`
 
-### Cleanup
-- [x] Removed `libs/lolib-3.0.0.jar` (unused)
-- [x] Removed CODE_OF_CONDUCT.md, SECURITY.md
-- [x] Added `bin/` to .gitignore
-- [x] Configs rewritten: clean, English, no Russian/Spacelegacy
+### Configs
+- [x] All rewritten: clean, English comments, no Spacelegacy palette

-## 🟡 CODE QUALITY ISSUES (HIGH PRIORITY)
+## 🟡 REMAINING (COULD DO)
 
-### 1. Max 3 Files Per Folder
+### 1. Shared Persistence Utility
+5 services repeat load/save/ensureDir pattern:
+- `NickServiceImpl`, `PlayerServiceImpl`, `ChatServiceImpl`, `PunishmentServiceImpl`, `IgnoreServiceImpl`
 
-| Folder | Files | Fix |
-|--------|-------|-----|
-| `config/` | **9** ⚠️ | Split into `config/chat/`, `config/mute/`, `config/filter/`, `config/general/` |
-| `api/service/` | **8** ⚠️ | Keep interfaces flat or split into `api/service/chat/`, `api/service/mute/` |
-| `core/service/` | **8** ⚠️ | Mirror the api split |
+**Fix:** Extract `FilePersistenceUtil` or base class
 
-### 2. DRY: `AppearanceConfig.loadEmojiCache()` Called Twice
+### 2. Mute Duration Permissions Not Declared in plugin.yml
+`lochat.mute.dur.5m`, `lochat.mute.dur.3h`, `lochat.mute.reason.*` — used in code/configs but missing from plugin.yml declarations.
 
-**File:** `config/AppearanceConfig.java:23-31`
-- `init()` calls `super.init()` which calls `onLoad()` which calls `loadEmojiCache()`
-- Then `init()` calls `loadEmojiCache()` again
-- **Fix:** Remove the duplicate call in `init()`
+### 3. DIP: Service Locator Anti-Pattern
+`ServiceRegistry.get(Xxx.class)` used everywhere instead of constructor DI. Big refactor.
 
-### 3. SRP: `ConfigManager.java` (278 lines)
+### 4. DRY: PM Send Logic Duplicated
+`MsgCommand` + `ReplyCommand` still have near-identical send logic.
 
-God class with 60+ methods across 10+ concerns:
-- Config orchestration
-- Chat settings (global, local, PM)
-- Mention settings
-- Clear chat state mutation
-- Announcement settings
-- Join/quit/death message settings
-
-**Fix:** Split into `ChatConfig`, `PmConfig`, `MentionConfig`, `ClearChatConfig`, `AnnouncementConfig`, `CustomMessagesConfig`
-
-### 4. OCP: `AdvancedMessageFilter.filterMessage()`
-
-Hardcoded pipeline of 7 filters. Adding a new filter requires modifying this method.
-
-**Fix:** Dynamic `List<Filter>` pipeline with registration
-
-### 5. ISP: `MessagingService` (fat interface)
-
-16 methods across 4 concerns: PM + Spy + Ignore + Persistence
-
-**Fix:** Split into `PrivateMessageService`, `SpyService`, `IgnoreService`, `PersistableService`
-
-### 6. DIP: Service Locator Anti-Pattern
-
-`ServiceRegistry.get(Xxx.class)` used everywhere instead of constructor DI.
-
-**Fix:** Pass required services via constructor parameters
-
-### 7. DRY: 12 Commands Duplicate Constructor Pattern
-
-Commands like `MsgCommand`, `ReplyCommand`, `IgnoreCommand`, `MuteCommand`, `BanCommand` etc. don't use `BaseCommand` hierarchy and repeat the same field/constructor/permission pattern.
-
-**Fix:** Migrate all to `PlayerCommand` / `AdminCommand`
-
-### 8. DRY: PM Send Logic Duplicated
-
-`MsgCommand.java:48-59` and `ReplyCommand.java:47-57` have identical PM send code.
-
-**Fix:** Extract to shared method/service
-
-### 9. KISS: `MuteCommand.onCommand()` (~100 lines)
-
-High complexity: argument parsing, flags, fallback logic, permission checks, broadcast logic, voice-mute.
-
-**Fix:** Decompose into `MuteRequest` parser + `MuteExecutor` service
-
-### 10. OOP: Leaked Internals
-
-- `LoChat.getInstance()` — singleton abuse
-- `LoChat` exposes 7+ internal components via public getters
-- `ChatEventListener` casts to concrete `PlayerServiceImpl`
-- `BaseConfig` has `protected` mutable fields
+### 5. PM Send Logic Duplicated Between MsgCommand and ReplyCommand
 
 ---
 
-## 🔵 MEDIUM PRIORITY
+## 🔵 LOW PRIORITY
 
-### 11. Dual Message Configs
+### 6. Tests
+Only 4 test files for 150+ main files. Very low coverage.
 
-`MessageConfig.java` (root, path-based) and `MessagesConfig.java` (config/, typed getters) overlap.
+### 7. Aho-Corasick for Swear Filter
+Performance optimization for word filtering.
 
-**Fix:** Unify into single `MessageConfig`
-
-### 12. Filter Classes Don't Share Interface
-
-`core/filter/filters/*.java` are standalone. `CooldownFilter`/`MuteFilter` implement `MessageFilter` from api.
-
-**Fix:** Make all filters implement `MessageFilter`
-
-### 13. 5+ Services Repeat Load/Save/Persistence
-
-`NickServiceImpl`, `PlayerServiceImpl`, `ChatServiceImpl`, `PunishmentServiceImpl` all have their own file I/O.
-
-**Fix:** Shared persistence utility
-
-### 14. Mute Duration Permissions Not Declared in plugin.yml
-
-`lochat.mute.dur.5m`, `lochat.mute.dur.3h`, `lochat.mute.reason.*` — used in code/configs but missing from plugin.yml.
-
----
-
-## ⚪ LOW PRIORITY
-
-### 15. Performance: Aho-Corasick for Swear Filter
-
-### 16. Discord Rate Limiter
-
-### 17. Tests: Only 4 test files (150 main files)
-
-### 18. `.project`, `.classpath`, `.settings/` should be gitignored
+### 8. Discord Rate Limiter
+Prevent rate limiting when sending many webhook messages.
