+
+### 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.
