+
+### Components:
+1. **`Persona.java` (Enum Enhancement):**
+   - Add `JUDITE` (SAC/Telemarketing persona) and `NARRADOR` (Fantasy narrator).
+   - Add `displayTag()` (e.g. "Judite", "Zoeiro", "Amigão") and `tagColor()` (Adventure `NamedTextColor`).
+   - Add persona-specific system prompts while maintaining the security invariant (`GUARD`).
+
+2. **`PlayerMemory.java` (New Persistent Service):**
+   - Manages `plugins/Canalhandia/ia-memoria.yml`.
+   - Thread-safe, cached in-memory with disk persistence.
+   - Stores per-player:
+     - Selected persona (`judite`, `zoeiro`, etc.) or `null` (inherit server default).
+     - Persistent compressed summary of past conversations.
+     - List of key facts learned about the player (e.g., base coordinates, preferred building materials, fear of mobs).
+   - Provides sliding-window compression: auto-condenses turns when memory exceeds thresholds.
+
+3. **`Tools.java` (Expanded Function Calling):**
+   - Add `lugares_jogador` function: fetches recent deaths from `DeathLog`, saved coordinates from `Notes`, and current biome/world.
+   - Update definitions JSON to make the tool discoverable to the LLM.
+
+4. **`Ai.java` (Orchestrator Updates):**
+   - Integrate `PlayerMemory`.
+   - Resolve effective persona per player (`playerMemory.persona(player)` -> fallback `settings.aiPersona()`).
+   - In `compose()`: inject effective persona tone + `playerMemory.formatContext(player)` + location summary.
+   - In `deliver()` and `style()`: render dynamic tag `Msg.tag(persona.displayTag(), persona.tagColor())` instead of fixed `[IA]`.
+   - Update `saySomething()` to support persona-specific spontaneous events.
+
+5. **`CanalhandiaCommand.java` (CLI & Interaction):**
+   - Enhance `/ia persona [nome]` to set per-player persona or list available personas with descriptions and click-to-select suggestions.
+   - Add `/ia persona padrao` to reset preference.
+   - Add `/ia status` and `/ia esquecer`.
+
+6. **`Canalhandia.java` & Event Hooks (Event Expansion):**
+   - Wire expanded event triggers into `saySomething()`:
+     - Player joins (`aiWelcome`)
+     - Player death streaks / notable deaths (`onDeath`)
+     - Milestones & custom achievements (`onMilestone`)
+     - Raid and boss victories (`onBossDefeat`)
+
+---
+
+## 2. File Touches
+
+1. `src/main/java/dev/marcospaulo/canalhandia/Persona.java` — Add `JUDITE`, `NARRADOR`, tags, colors, and prompts.
+2. `src/main/java/dev/marcospaulo/canalhandia/PlayerMemory.java` — New class for persistent per-player memory & compression.
+3. `src/main/java/dev/marcospaulo/canalhandia/Tools.java` — Add `lugares_jogador` tool and integration with `DeathLog` & `Notes`.
+4. `src/main/java/dev/marcospaulo/canalhandia/Ai.java` — Integrate `PlayerMemory`, dynamic persona tags, prompt composition.
+5. `src/main/java/dev/marcospaulo/canalhandia/CanalhandiaCommand.java` — Subcommands for `/ia persona`, `/ia status`, `/ia esquecer`.
+6. `src/main/java/dev/marcospaulo/canalhandia/Canalhandia.java` — Wire `PlayerMemory` lifecycle, expand event hooks.
+7. `src/test/java/dev/marcospaulo/canalhandia/PersonaTest.java` — Unit tests for personas, tags, and system prompts.
+8. `src/test/java/dev/marcospaulo/canalhandia/PlayerMemoryTest.java` — Unit tests for YAML storage, compression, and per-player state.
+9. `src/test/java/dev/marcospaulo/canalhandia/ToolsTest.java` — Unit tests for `lugares_jogador` and tool execution.
+
+---
+
+## 3. Risks & Mitigations
+
+- **Risk:** Token context blowup from memory/chat history.
+  - *Mitigation:* Hard-cap memory summary length (max 300 chars) and max facts (max 5 items) per player.
+- **Risk:** Thread safety when reading player memory in async AI tasks.
+  - *Mitigation:* Synchronize all `PlayerMemory` reads/writes under monitor; snapshot memory context as immutable strings on main thread before async dispatch.
+- **Risk:** API costs from spontaneous event comments.
+  - *Mitigation:* All events remain strictly governed by `Budget` with cooldown windows and hourly/daily spend limits.

+# Spec: AI Multi-Personalities, Judite (SAC), Dynamic Tags, Persistent Memory & Event Expansion
+
+## 1. Objective & Motivation
+
+Transform the `ia` module in the `Canalhandia` plugin into a rich, personalized companion system:
+1. **Per-Player AI Selection:** Each player can pick their own AI persona (or use server default).
+2. **Dynamic Chat Tags:** Replace static `[IA]` tag with the active persona's name (e.g. `[Judite]`, `[Zoeiro]`, `[Amigão]`, `[Seco]`, `[Aldeão]`, `[Narrador]`).
+3. **Judite Roleplay Persona:** A hilarious Brazilian SAC/telemarketing attendant (Porta dos Fundos style) with fictitious protocols, bureaucratic quirks, hold music jokes, and deadpan efficiency.
+4. **Persistent Compressed Memory (`ia-memoria.yml`):** Retain player memories, key facts, past locations, and sliding-window conversation summaries across server reboots.
+5. **Rich Location & Stat Grounding:** Grant the AI direct knowledge of places the player has been (death locations via `DeathLog`, saved pins via `Notes`, current biomes/coords, statistics).
+6. **Expanded Event Reactivity:** Broaden spontaneous AI commentary to include death streaks, boss/raid triumphs, milestone achievements, first-time dimension visits, and custom join greetings with persona-specific voice.
+
+---
+
+## 2. Personas Specification
+
+### A. Tag & Persona Definitions
+
+| Persona Key | Display Tag | Tone & Character Description |
+|---|---|---|
+| `judite` | `[Judite]` | Atendente de SAC/telemarketing burocrática e impaciente, viciada em gerundismo ("estaremos verificando no sistema"), gera números de protocolo ("Protocolo 2026-MC-..."), pede para aguardar na linha, cobra pendências (fome/vida baixa) com frieza corporativa e dá respostas precisas. |
+| `zoeiro` | `[Zoeiro]` | Veterano debochado do servidor que usa mortes e estatísticas contra o jogador, mantendo o bom humor. |
+| `amigao` | `[Amigão]` | Amigo paciente, caloroso e prestativo, ideal para acolher novatos sem sarcasmo. |
+| `seco` | `[Seco]` | Minimalista, direto e sarcástico, 1 a 2 frases curtas sem emoção. |
+| `aldeao` | `[Aldeão]` | Solene e místico, falando como um sábio aldeão ancestral de Minecraft. |
+| `narrador` | `[Narrador]` | Narrador épico e dramático de RPG de fantasia medieval ("Eis que o bravo viajante indaga..."). |
+| `neutro` | `[IA]` | Assistente direto, neutro e sem persona marcante. |
+
+### B. Dynamic Tag Rendering
+- In `/ia`, `/iap`, and chat responses: Tag is rendered as `Msg.tag(persona.displayTag(), persona.tagColor())` instead of fixed `[IA]`.
+- Java players retain rich hover cards detailing the persona name and question prompt.
+
+---
+
+## 3. Player Preferences & Commands
+
+- `/ia persona` / `/ia personalidade`: Lists all available personas and highlights the player's active selection.
+- `/ia persona <nome>`: Sets the player's personal persona (persisted in `ia-memoria.yml`).
+- `/ia persona padrao` / `/ia persona reset`: Resets to the server-wide default persona configured in `config.yml`.
+- `/ia status`: Displays active persona, memory status, and summary of stored facts for the player.
+- `/ia esquecer`: Clears the player's stored conversation memory/facts.
+
+---
+
+## 4. Persistent Memory & Chat Compression Engine (`PlayerMemory`)
+
+### File: `plugins/Canalhandia/ia-memoria.yml`
+
+```yaml
+players:
+  <uuid>:
+    name: "Diguin_n"
+    persona: "judite"
+    updated_at: 1771450000000
+    summary: "Jogador explorou o Nether e perguntou sobre poções de agilidade. Tem base na vila das coordenadas 120, 64, -300."
+    facts:
+      - "Tem base na vila (120, 64, -300)"
+      - "Morreu recentemente no Void"
+      - "Gosta de criar axolotes e golfinhos"
+```
+
+### Memory Mechanics:
+1. **Short-Term Session Memory:** Live exchanges stored in memory for immediate follow-ups.
+2. **Key Facts Extraction / Journaling:** Maintained per player to keep long-term context across restarts.
+3. **Sliding Compression:** When conversation turns exceed limits, compress previous interactions into the player's persistent summary string, ensuring bounded token usage.
+
+---
+
+## 5. Context Grounding & Tools
+
+- **Tool `lugares_jogador`:**
+  - Retrieves player's recent deaths from `DeathLog` (`mortes.yml`).
+  - Retrieves player's saved pins/bases from `Notes` (`notas.yml`).
+  - Retrieves current coordinates, world dimension, and biome.
+- **Tool `estatisticas_jogador`:**
+  - Reads mined blocks, mob kills, total deaths, playtime from `OfflineStats`.
+- **Tool `conquistas_jogador`:**
+  - Reads unlocked titles and achievements.
+  - Server leaderboards, recent public milestones, online player list.
+
+---
+
+## 6. Expanded Event Engine
+
+The AI can react to diverse gameplay triggers (gated by `aiBudget` and configurable settings):
+1. **Death Streaks & Notable Deaths:** Void deaths, falling, explosions, Warden/Wither encounters.
+2. **Player Joins (`aiWelcome`):** Persona greets returning player with contextual facts (e.g. Judite mentions pending tickets or absence duration).
+3. **Milestone Crossings:** When a player crosses round milestones (e.g. 100km walked, 10,000 blocks mined) or earns rare achievements.
+4. **Boss Defeats & Raids:** Dragon/Wither defeats or raid victories.
+
+---
+
+## 7. Acceptance Criteria
+
+1. All existing 316 unit tests continue to pass without regressions.
+2. New unit tests covering:
+   - `PersonaTest`: Validation of all personas including `JUDITE` and `NARRADOR`, display tags, system prompts, safety guard invariant.
+   - `PlayerMemoryTest`: YAML serialization, compression, fact storage, and per-player persona retention.
+   - `ToolsTest`: Verification of `lugares_jogador` and updated tool definitions.
+   - `AiTagTest`: Dynamic persona tag rendering in chat and hover styling.
+   - `EventTest`: Event triggers formatting prompts with appropriate persona context.
+3. `/ia persona <nome>` persists choices across restarts.
+4. Full clean compilation with `mvn test` and `mvn package`.

+# Plan: Módulo Nativo de Chunk Loader
+
+## Arquitetura
+1. **`ChunkLoader.java` (Record puro)**
+   - `id`, `ownerUuid`, `ownerName`, `world`, `x`, `y`, `z`, `chunkX`, `chunkZ`, `createdAt`.
+   - Métodos utilitários: `chunkCoords()`, `blockCoords()`, etc.
+
+2. **`ChunkLoaders.java` (Gerenciador e Persistência)**
+   - Gerencia lista em memória sincronizada `List<ChunkLoader>`.
+   - Persistência em `plugins/Canalhandia/chunks.yml` com salvamento assíncrono.
+   - Métodos: `add()`, `remove()`, `byChunk()`, `byOwner()`, `loadAll()`, `unloadAll()`, `playerLimit(Player)`.
+   - Executa `world.addPluginChunkTicket` e `world.removePluginChunkTicket`.
+
+3. **`Module.java` & `Settings.java`**
+   - Adiciona `CHUNKLOADER("chunkloader", "Âncoras de carregamento contínuo de chunks")` no enum `Module`.
+   - Adiciona configurações em `Settings.java` (limite padrão, material do bloco, raio de partículas).
+
+4. **`ChunkLoaderListener.java` (Eventos do Mundo)**
+   - `BlockPlaceEvent`: Detecta colocação da Âncora, verifica permissões/limites LuckPerms, registra loader e ticket.
+   - `BlockBreakEvent`: Protege quebra por não-donos, remove ticket e devolve o item customizado.
+   - `BlockExplodeEvent` / `EntityExplodeEvent`: Impede destruição por explosão.
+   - `BlockPistonExtendEvent` / `BlockPistonRetractEvent`: Impede movimentação por pistão.
+
+5. **`CanalhandiaCommand.java` & `ChunkLoaderCommand.java`**
+   - Subcomandos de `/chunkloader` / `/ancora` e tab-completion completo.
+
+6. **`BlueMapBridge.java`**
+   - Cria conjunto de marcadores para chunk loaders no mapa web.
+
+7. **Testes Unitários (`ChunkLoaderTest.java`)**
+   - Validação de regras de permissão, cálculo de limite, serialização em YAML e exclusão de duplicatas na mesma chunk.
+
+## Riscos & Mitigações
+- **Risco:** Descarregamento incorreto no shutdown do servidor gerando tickets órfãos.
+  - **Mitigação:** `unloadAll()` limpo em `onDisable()`, e tickets do Paper (`PluginChunkTicket`) são re-validados no `onEnable()`.
+- **Risco:** Jogador contornar limite colocando em mundos não permitidos ou múltiplas na mesma chunk.
+  - **Mitigação:** Validação estrita de unicidade de chunk (`byChunk(world, cx, cz) != null`) e verificação de limite antes de aceitar o evento.

+# Spec: Módulo Nativo de Chunk Loader (Canalhandia)
+
+## 1. Visão Geral
+Adiciona ao plugin `Canalhandia` um módulo nativo, performático e equilibrado de **Chunk Loading** para o Paper 1.21.x.
+Permite que jogadores mantenham áreas/chunks específicas carregadas para farms, redstone e sistemas automatizados usando a API nativa de tickets do Paper (`addPluginChunkTicket`), com permissões granulares e limites por cargo configuráveis via **LuckPerms**.
+
+---
+
+## 2. Requisitos e Mecânicas
+
+### 2.1. Bloco e Item Customizado: "Âncora de Chunk" (Chunk Anchor)
+- **Item Base:** `RESPAWN_ANCHOR` ou `LODESTONE` com nome formatado (`§b§lÂncora de Chunk`), lore explicativa e `PersistentDataContainer` identificando o item customizado.
+- **Receita de Crafting:**
+  - Configurada em `config.yml` (ex: 4 Obsidianas Choronas, 4 Diamantes, 1 Estrela do Nether ou Olho do Fim).
+  - Desbloqueia automaticamente no livro de receitas ao obter os ingredientes.
+
+### 2.2. Colocação e Restrições
+- Ao colocar o bloco (`BlockPlaceEvent`):
+  - Verifica se o jogador possui permissão `canalhandia.chunkloader`.
+  - Verifica o limite de loaders do jogador no LuckPerms:
+    - Lê permissões numéricas: `canalhandia.chunkloader.limite.<N>` (ex: `limite.1`, `limite.2`, `limite.5`, `limite.10`).
+    - Pega o maior `<N>` encontrado nas permissões do jogador.
+    - Se não houver permissão numérica explícita, usa `chunkloader.limite-padrao` do `config.yml` (padrão: 1).
+    - Administradores com `canalhandia.admin` não têm limite.
+  - Verifica se já existe um loader ativo na mesma chunk (máximo 1 por chunk).
+  - Se aprovado:
+    - Ativa o ticket na chunk: `world.addPluginChunkTicket(chunkX, chunkZ, plugin)`.
+    - Salva em `chunks.yml`.
+    - Cria partícula/efeito sonoro de ativação.
+    - Registra marcador no BlueMap (opcional/configurável).
+    - Envia mensagem de confirmação informando quantas âncoras o jogador está usando (ex: `1/3 ativas`).
+
+### 2.3. Remoção e Proteção
+- **Proteção:** Apenas o dono da âncora ou administradores (`canalhandia.admin`) podem quebrar o bloco (`BlockBreakEvent`).
+- **Explosões / Pistões:** Protegido contra destruição acidental por TNT/Creeper (`EntityExplodeEvent`, `BlockExplodeEvent`) e empurrão por pistão (`BlockPistonExtendEvent`).
+- Ao quebrar:
+  - Remove o ticket de chunk do Paper: `world.removePluginChunkTicket(chunkX, chunkZ, plugin)`.
+  - Remove de `chunks.yml` e do BlueMap.
+  - Devolve o item "Âncora de Chunk" ao jogador.
+
+### 2.4. Persistência e Ciclo de Vida
+- Arquivo `plugins/Canalhandia/chunks.yml`:
+  - Armazena ID, UUID do dono, nome, mundo, coordenadas (x, y, z), chunk (cx, cz) e data de criação.
+- **No `onEnable()` do plugin:** Carrega `chunks.yml` e registra `addPluginChunkTicket` em todas as chunks salvas.
+- **No `onDisable()` do plugin:** Remove os tickets do plugin de forma limpa.
+
+### 2.5. Comandos (`/chunkloader` ou `/ancora`)
+- `/chunkloader` ou `/ancora`:
+  - `/chunkloader info` — Mostra o status da chunk atual (se está carregada por um loader e por quem) e seus limites de uso.
+  - `/chunkloader listar` — Lista todas as âncoras ativas do jogador com coordenadas e link para deletar/desativar.
+  - `/chunkloader remover <id>` — Desativa remotamente uma âncora do próprio jogador.
+  - `/chunkloader receita` — Mostra a receita de crafting.
+  - `/chunkloader admin listar [jogador]` — (Admin) Lista todos os chunk loaders do servidor.
+  - `/chunkloader admin remover <id>` — (Admin) Força a remoção de qualquer loader.
+  - `/chunkloader reload` — (Admin) Recarrega configurações e sincroniza tickets.
+
+---
+
+## 3. Integração com LuckPerms
+Nós de permissão:
+- `canalhandia.chunkloader` — Habilita o jogador a craftar, colocar e gerenciar âncoras.
+- `canalhandia.chunkloader.limite.<N>` — Define o limite máximo de âncoras ativas para o cargo (ex: `canalhandia.chunkloader.limite.3` para VIP).
+- `canalhandia.chunkloader.admin` — Acesso total aos comandos administrativos de chunk loading.
+
+---
+
+## 4. Critérios de Aceite
+1. Módulo pode ser ativado/desativado via `config.yml` e `/canalhandia modulo chunkloader`.
+2. Bloco colocado registra ticket via `world.addPluginChunkTicket` que sobrevive a reboots via `chunks.yml`.
+3. Limites de permissão do LuckPerms são respeitados estritamente.
+4. Blocos não podem ser roubados ou quebrados por terceiros.
+5. Suíte de testes unitários (`ChunkLoaderTest.java`) com 100% de aprovação.
