+Eagle0 is a multi-language gaming system combining strategic turn-based gameplay (Eagle) with tactical hex-based combat (Shardok). The system integrates LLM-based narrative generation and supports both human and AI players.
 
 ## Architecture
 
 **Three-Tier Game System:**
-
 - **Unity Client (C#)**: Real-time strategy game client with integrated tactical combat UI
 - **Eagle (Scala)**: Strategic layer managing turn-based gameplay, diplomacy, hero progression, and province control

+- **Shardok (C++)**: Tactical layer handling real-time hex-based combat simulation with performance-critical battle resolution
 
 **Communication Flow:**
-
 ```
 Unity Client ↔ Eagle (gRPC streaming) ↔ Shardok (internal gRPC) 
 ```
 
 **Key Entry Points:**
-
 - `/src/main/csharp/net/eagle0/clients/unity/eagle0/` - Unity C# game client
 - `/src/main/scala/net/eagle0/eagle/Main.scala` - Eagle strategic game server
 - `/src/main/cpp/net/eagle0/shardok/shardok_server_main.cpp` - Shardok tactical server
 
 **Protocol Buffer Architecture:**
-
 - Extensive use of protobuf for type-safe communication
 - Separate packages: `api/` (client-facing), `internal/` (server state), `views/` (client projections)
 - Event sourcing pattern with immutable action history

 ```
 
-## AI Algorithm Selection
-
-Eagle0 supports two AI algorithms for tactical combat decision-making:
-
-### Iterative Deepening AI (Default)
-
-The original minimax-based AI with sophisticated randomness handling:
-
-- **Advantages**: Proven, sophisticated randomness evaluation, comprehensive lookahead
-- **Use cases**: Production builds, scenarios requiring precise evaluation
-- **Performance**: Single-threaded, thorough evaluation
-
-### Monte Carlo Tree Search AI (MCTS)
-
-Modern MCTS-based AI with multithreading support:
-
-- **Advantages**: Multithreaded, better performance on modern CPUs, anytime algorithm
-- **Use cases**: Performance testing, scenarios requiring fast decisions
-- **Performance**: Multithreaded, adaptive depth based on time budget
-
-### Switching Between Algorithms
-
-The algorithm is selected at **runtime** via the ShardokAIClient constructor:
-
-```cpp
-// Using Iterative Deepening AI (default)
-ShardokAIClient client(playerId, isDefender, hexMap, settings);
-// OR explicitly:
-ShardokAIClient client(playerId, isDefender, hexMap, settings, AIAlgorithmType::ITERATIVE_DEEPENING);
-
-// Using MCTS AI
-ShardokAIClient client(playerId, isDefender, hexMap, settings, AIAlgorithmType::MCTS);
-```
-
-```bash
-# Build the server (includes both AI algorithms)
-bazel build //src/main/cpp/net/eagle0/shardok:shardok-server
-
-# Test both algorithms
-bazel test //src/test/cpp/net/eagle0/shardok/ai:ai_iterative_deepening_test
-bazel test //src/test/cpp/net/eagle0/shardok/ai:ai_mcts_test  # If available
-
-# Performance tests
-./scripts/ai_perf_test.sh  # Uses whatever algorithm the server is configured to use
-```
-
-Both implementations are compatible with all existing interfaces and produce the same `SearchResult` structure.
-
-**Note**: Both implementations are documented in `src/main/cpp/net/eagle0/shardok/ai/AI_SCORING_SYSTEM.md`, including
-recommendations for improving MCTS randomness handling.
-
-The AI algorithm selection is made at runtime when creating ShardokAIClient instances, allowing different AI strategies
-to be used for different players or game situations within the same server process.
-
 ## Language-Specific Patterns
 
 **Scala (Strategic Layer):**
-
 - Use `EngineImpl.scala` for core game logic modifications
 - Follow event sourcing pattern - all changes through immutable actions
 - gRPC streaming for real-time client updates via `EagleServiceImpl.scala`
 - LLM integration in `/common/llm_integration/` for narrative generation
 
 **C++ (Tactical Layer):**
-
 - Performance-critical combat in `ShardokEngine.hpp/.cpp`
 - FlatBuffers for efficient serialization in `/flatbuffer/` directory
 - AI systems in `/ai/` subdirectory with pluggable strategy selectors
 - Extensive unit testing with Google Test framework
 
 **Protocol Buffers:**
-
 - Three-layer structure: `api/` (client), `internal/` (server), `views/` (projections)
 - Use `shardok_internal_interface.proto` for Eagle-Shardok communication
 - Maintain backward compatibility when modifying existing messages
 
 **C# (Unity Client):**
-
 - Located in `/src/main/csharp/net/eagle0/clients/unity/eagle0/`
 - Uses Unity 6 (6000.0.32f1) with comprehensive protobuf integration (100+ .proto files)
 - Key components: `EagleConnection.cs` (gRPC client), `EagleGameController.cs` (main game logic)

-### Scala Testing Patterns
-
-**Use `inside()` instead of `asInstanceOf` for type matching in tests:**
-
-Never use `asInstanceOf` in tests. Instead, use ScalaTest's `inside()` pattern for safe type matching:
-
-```scala
-// BAD - don't do this
-val changedHero = result.changedHeroes.head.asInstanceOf[ChangedHeroC]
-changedHero.heroId shouldBe 19
-
-// GOOD - use inside() pattern
-import org.scalatest.Inside.inside
-
-inside(result.changedHeroes.head) { case changedHero: ChangedHeroC =>
-  changedHero.heroId shouldBe 19
-  changedHero.vigorChange shouldBe StatDelta(17.2)
-}
-```
-
-The `inside()` pattern:
-- Provides better error messages when the type doesn't match
-- Is idiomatic ScalaTest
-- Works with pattern matching for more complex assertions
-

 **Important notes:**
-
 - Run tests multiple times (3-5) to account for performance variance
 - Focus on commands evaluated at each depth rather than total commands
 - Commands at different depths aren't directly comparable (depth 3 is more valuable than depth 2)
-- **Always test performance changes** - what seems like an optimization may sometimes have unexpected overhead or
-  behavior changes.
-
-## Troubleshooting Scala Build Errors
-
-### MissingType Errors
-
-When you see errors like:
-```
-dotty.tools.dotc.core.MissingType: Cannot resolve reference to type net.eagle0.eagle.internal.game_state.type.GameState
-```
-
-**This is NOT a Scala compiler crash.** This is a missing dependency in BUILD.bazel.
-
-**How to fix:**
-1. Identify the missing type from the error message (e.g., `game_state.GameState`)
-2. Find the Bazel target that provides this type (e.g., `//src/main/protobuf/net/eagle0/eagle/internal:game_state_scala_proto`)
-3. Add it to the `deps` of the failing target
-4. If the type appears in a public method signature, also add it to `exports` so downstream targets can see it
-
-**Common pattern:** When adding a method to a class that takes or returns a proto type, the proto dependency often needs to be added to both `deps` AND `exports`.
-
-### Bazel Clean
-
-**NEVER run `bazel clean` without asking first.** It rarely fixes actual issues and wastes significant rebuild time. The issues that seem like they need `bazel clean` are usually:
-- Missing imports in Scala code
-- Missing dependencies in BUILD.bazel
-- Missing exports for types used in public signatures
+- **Always test performance changes** - what seems like an optimization may sometimes have unexpected overhead or behavior changes.

-# Deproto Migration Plan
-
-This document tracks the migration from protobuf types to native Scala models inside the Eagle game engine.
-
-## Architectural Decisions
-
-1. **Keep proto for persistence**: Yes - protobuf is used for persisting game state
-2. **Keep proto for Shardok communication**: Yes - protobuf is used for Eagle-Shardok gRPC communication
-3. **Use Scala views inside the library**: Yes - use native Scala types like `ProvinceView`, `FactionView`, `HeroView`, etc. within the library code
-
-## Recent Completed Work
-
-### GameState Round-Trip Elimination (PRs #4913, #4914, #4915)
-
-Eliminated wasteful Scala→proto→Scala conversions in the hot path:
-
-1. **LLM Pipeline** (#4913): `LlmRequestWithGameState` now uses Scala `GameState` instead of proto. All ~38 prompt generators updated to use Scala model types (`FactionT`, `HeroT`, `ProvinceT`).
-
-2. **ActionWithResultingState Caching** (#4914): Added `precomputedScalaState: Option[GameState]` to cache Scala state when available, avoiding `fromProto()` conversion in `stateAfter()`.
-
-3. **PostResults Simplification** (#4915): Changed `PostResults.gameState` from proto to `Option[GameState]` (Scala), eliminating `toProto()` calls when creating PostResults.
-
-## Migration Pattern
-
-The codebase follows a **Legacy* pattern** for separating proto-dependent and protoless code:
-
-- **Protoless utilities**: `FactionUtils`, `HeroUtils`, `ProvinceUtils`, `ProvinceDistances`, etc.
-- **Proto-dependent utilities**: `LegacyFactionUtils`, `LegacyHeroUtils`, `LegacyProvinceUtils`, `LegacyProvinceDistances`, etc.
-
-When migrating a file:
-1. Create a `Legacy*` version containing the proto-dependent methods
-2. Keep the original file name for protoless methods
-3. Update callers to use the appropriate version based on their context
-
-## Migration Status
-
-### Fully Protoless (no proto imports)
-
-**Utilities:**
-- [x] `FactionUtils` - has protoless `ownedNeighbors` method
-- [x] `ProvinceDistances` - split into protoless + `LegacyProvinceDistances`
-- [x] `SwornBrotherChooser` - fully protoless (removed `bestChoiceProto`)
-
-**Command Selectors (all use native GameState):**
-- [x] `AllianceOfferCommandSelector`
-- [x] `AlmsCommandSelector`
-- [x] `AttackCommandChooser`
-- [x] `ExpandCommandSelector`
-- [x] `HeroGiftCommandSelector`
-- [x] `ImproveCommandSelector`
-- [x] `MarchTowardProvinceCommandChooser` - in AI folder, uses native GameState (callers convert)
-- [x] `OrganizeCommandSelector`
-- [x] `RansomOfferHelpers`
-- [x] `SeekMoreLeadersCommandChooser` - in AI folder, uses native GameState
-- [x] `TruceOfferCommandSelector`
-- [x] `TrustForDiplomacy`
-
-**Quest Command Selectors (all protoless):**
-- [x] `AllianceQuestCommandChooser`
-- [x] `AlmsAcrossRealmQuestCommandChooser`
-- [x] `AlmsToProvinceQuestCommandChooser`
-- [x] `DismissSpecificVassalCommandChooser`
-- [x] `GiveToHeroesAcrossRealmQuestCommandChooser`
-- [x] `GiveToHeroesInProvinceQuestCommandChooser`
-- [x] `ImproveQuestCommandChooser`
-- [x] `QuestCommandChooser`
-- [x] `TruceCountQuestCommandChooser`
-- [x] `TruceWithFactionQuestCommandChooser`
-
-### Fully Protoless
-
-- [x] `AIClientUtils` - has protoless overloads (`takenHeroIdsForMarchTowardFocus`, `mostPowerfulHeroes`)
-- [x] `ProvinceGoldSurplusCalculator` - fully protoless (callers use converters)
-- [x] `HeroSelector` - fully protoless (removed dead `minimallyFatiguedHeroesProto`)
-
-### Blocked (still uses proto GameState)
-
-- [ ] `CommandChoiceHelpers` - main target, uses proto GameState extensively
-  - Depends on many Legacy* utils
-  - Central hub called by many command selectors
-- [ ] `AttackDecisionCommandChooser` - uses proto GameState, converts internally
-- [ ] `CommandChooser` - trait uses proto GameState in signature
-- [ ] `FulfillQuestsCommandSelector` - takes proto, converts to native immediately
-  - Called by `MidGameAIClient` which uses proto GameState
-
-## Next Steps
-
-### Phase 1: CommandChoiceHelpers Migration
-
-The main blocker is `CommandChoiceHelpers.scala` which uses proto `GameState` extensively. Strategy:
-
-1. **Add Scala overloads** to `CommandChoiceHelpers` methods that currently take proto GameState
-2. **Update internal helpers** to use Scala types where possible
-3. **Migrate callers incrementally** - command selectors that are already protoless can switch to Scala overloads
-
-### Phase 2: CommandChooser Trait
-
-Once CommandChoiceHelpers is protoless:
-
-1. Add Scala `GameState` overload to `CommandChooser.choose()` method
-2. Update implementations (`AttackDecisionCommandChooser`, etc.) to use Scala internally
-3. Eventually deprecate proto overloads
-
-### Phase 3: MidGameAIClient
-
-The top-level AI client still uses proto GameState. Once lower layers are protoless:
-
-1. Convert `MidGameAIClient` to use Scala GameState internally
-2. Only convert at the boundary when receiving from/sending to gRPC
-
-## Key Files
-
-### Protoless Model Types
-
-- `src/main/scala/net/eagle0/eagle/model/state/game_state/GameState.scala` - native Scala GameState
-- `src/main/scala/net/eagle0/eagle/model/state/province/ProvinceView.scala` - province view type
-- `src/main/scala/net/eagle0/eagle/model/state/faction/FactionView.scala` - faction view type
-- `src/main/scala/net/eagle0/eagle/model/state/hero/HeroView.scala` - hero view type
-
-### Proto Converters
-
-- `src/main/scala/net/eagle0/eagle/model/proto_converters/game_state/` - converts between proto and Scala types
-
-## Notes
-
-- The AI client code (`src/main/scala/net/eagle0/eagle/ai/`) currently uses proto types extensively
-- `PerformUnaffiliatedHeroesAction` already uses protoless `GameState`
-- Migration should proceed incrementally: utilities first, then higher-level selectors/choosers

+# Actions and Commands Model Usage Analysis
+
+This document analyzes all actions and commands in `src/main/scala/net/eagle0/eagle/library/actions/impl` to determine which use Scala models vs protobuf models, based on BUILD.bazel dependencies.
+
+**Legend:**
+- ✅ **Scala Models Only** - Uses only `//src/main/scala/net/eagle0/eagle/model` dependencies
+- ❌ **Uses Protobuf** - Has dependencies on `//src/main/protobuf` targets
+- 🔄 **Partial Conversion** - Conversion attempted but blocked by dependencies
+
+## Summary
+
+Based on BUILD.bazel dependency analysis (2025-09-04):
+- **Total Commands Analyzed:** 40  
+- **Commands Fully Migrated (No Protobuf):** 36 (90%)
+- **Commands Still Using Protobuf:** 4 (10%)
+- **Actions:** Most still have protobuf dependencies
+- **Base Classes:** 8 protoless variants available, 6 still use protobuf
+
+## Conversion Insights
+
+Based on conversion attempt of `ResolveTruceOfferCommand` (see [PR #4379](https://github.com/nolen777/eagle0/pull/4379)):
+
+### Key Challenges Discovered
+
+1. **LLM Integration Dependencies**: Commands that use `DiplomacyResolutionLlmRequestGenerator` face challenges because the LLM system still expects protobuf enum types, not Scala model enums.
+
+2. **Inconsistent Package Naming**: Some files have inconsistent package declarations vs BUILD file locations (e.g., `generated_text_request_generators` in package vs `llm_request_generators` in BUILD).
+
+3. **Model Constructor Differences**: Scala model constructors (e.g., `TruceOffer`) have different required parameters than their protobuf counterparts, requiring more complex data mapping.
+
+4. **Type System Complexity**: Union types and type constraints become more complex when mixing protobuf and Scala model types during transition.
+
+5. **Cascading Dependency Issues**: Converting to `ActionResultC` requires extensive trait dependencies (`ChangedBattalionT`, `ChangedHeroT`, `GeneratedTextRequestT`, etc.) that create complex BUILD dependency graphs, unlike simple protobuf `ActionResult`.
+
+6. **BUILD Complexity**: Each Scala model conversion requires significantly more BUILD dependencies than protobuf equivalents, making incremental conversion difficult.
+
+7. **Build Verification Critical**: Any conversion must maintain working build state - even simple commands like `DefendCommand` can break main server build due to dependency cascades.
+### Successful Conversion Elements
+
+- ✅ Base class conversion (`SimpleAction` → `ProtolessSimpleAction`)
+- ✅ Import updates for most Scala model types
+- ✅ BUILD.bazel dependency updates for core action result types
+- ✅ Basic type conversions for simple cases
+
+### Recommended Conversion Strategy
+
+1. **Architecture-First Approach**: Convert base infrastructure (LLM generators, action result builders) before individual commands
+2. **Wrapper Pattern**: Use existing `Protoless*ActionWrapper` classes as templates for gradual transition
+3. **Dependency Analysis**: Map full dependency trees before attempting conversions to avoid cascading build failures
+4. **Batch Conversions**: Convert related commands together to minimize dependency conflicts
+5. **Build Verification**: **ALWAYS** verify `//src/main/scala/net/eagle0/eagle:eagle_server` and test suite build before creating PRs
+
+### Conversion Requirements
+
+**Before creating any PR:**
+- ✅ `bazel build //src/main/scala/net/eagle0/eagle:eagle_server` succeeds
+- ✅ `bazel test //src/test/scala/... --keep_going` passes (or doesn't introduce new failures)
+- ✅ All BUILD dependencies are correctly specified
+- ✅ Scalafmt and other linters pass

+### ⚠️ Commands Still Using Protobuf Dependencies
+
+These commands have protobuf dependencies in their BUILD.bazel files:
+
+| File | Build Target | Key Protobuf Dependencies | Migration Complexity |
+|------|--------------|---------------------------|---------------------|
+| DiplomacyCommand.scala | `diplomacy_command` | `diplomacy_option`, `diplomacy_offer`, `available_command` | High - Complex diplomacy |
+| ResolveAllianceOfferCommand.scala | `resolve_alliance_offer_command` | `diplomacy_offer`, `available_command`, `action_result` | High - Diplomacy |
+| ResolveBreakAllianceCommand.scala | `resolve_break_alliance_command` | `diplomacy_offer`, `available_command`, `action_result` | High - Diplomacy |
+| ~~ResolveRansomOfferCommand.scala~~ | ~~`resolve_ransom_offer_command`~~ | ~~**MIGRATED**~~ | ~~High - Diplomacy~~ |
+| ~~ResolveTributeCommand.scala~~ | ~~`resolve_tribute_command`~~ | ~~**MIGRATED**~~ | ~~High - Diplomacy~~ |
+
+**Total: 4 commands (10% of all commands)**
+
+### Migration Complexity Analysis
+
+**Low Complexity (0 commands)**: Single protobuf dependency
+- ~~All low complexity commands have been migrated~~
+
+**Medium Complexity (0 commands)**: API layer or simple state dependencies
+- ~~All medium complexity commands have been migrated~~
+
+**High Complexity (6 commands)**: Complex state or diplomacy
+- All diplomacy resolution commands (5) - need complete diplomacy model migration  
+- Commands with complex `game_state` dependencies (1)
+
+---
+
+## Diplomacy Helpers
+
+All diplomacy helpers use **Scala models only**:
+
+| File | Model Usage | Notes |
+|------|-------------|-------|
+| AllianceResolutionHelpers.scala | ✅ Scala Models Only | Uses `//src/main/scala/net/eagle0/eagle/model` only |
+| BreakAllianceResolutionHelpers.scala | ✅ Scala Models Only | Uses `//src/main/scala/net/eagle0/eagle/model` only |
+| InvitationResolutionHelpers.scala | ✅ Scala Models Only | Uses `//src/main/scala/net/eagle0/eagle/model` only |
+| RansomResolutionHelpers.scala | ✅ Scala Models Only | Uses `//src/main/scala/net/eagle0/eagle/model` only |
+| TruceResolutionHelpers.scala | ✅ Scala Models Only | Uses `//src/main/scala/net/eagle0/eagle/model` only |
+
+---
+
+## Migration Priority Analysis
+
+Based on the BUILD.bazel dependency analysis, here are the key findings and recommendations:
+
+### 🎯 High Impact Migration Targets
+
+**Core Dependencies Blocking Multiple Commands:**
+
+1. **`action_result_scala_proto`** - Used by 12+ commands
+   - Blocks: `DefendCommand`, `FreeForAllDecisionCommand`, diplomacy resolvers
+   - Impact: Would unlock many command migrations
+
+2. **`available_command_scala_proto` / `selected_command_scala_proto`** - Used by 10+ commands
+   - Blocks: All UI-interactive commands
+   - Impact: Would enable client-server interaction model migration
+
+3. **`game_state_scala_proto`** - Used by 8+ commands
+   - Blocks: Complex state-dependent commands
+   - Impact: Core state representation migration
+
+### 📊 Migration Tiers by Complexity
+
+**Tier 1 - Quick Wins (2 commands):**
+- `ArmTroopsCommand` - Only `battalion_type` dependency
+- `TrainCommand` - Only `battalion_type` dependency
+- **Effort:** Low, **Impact:** Demonstrates battalion model usage
+
+**Tier 2 - API Layer (5 commands):**
+- Commands blocked by `available_command`/`selected_command`
+- **Effort:** Medium, **Impact:** High (enables UI interaction models)
+
+**Tier 3 - Diplomacy Suite (6 commands):**
+- All `Resolve*Command` diplomacy commands
+- **Effort:** High, **Impact:** High (complete diplomacy model migration)
+- **Strategy:** Migrate as a group after diplomacy models are ready
+
+### 🏆 Success Metrics
+
+**Current Status:**
+- ✅ **82.5% of commands fully migrated** (33/40)
+- ✅ **All diplomacy helpers use Scala models**
+- ✅ **All protoless base classes available**
+- ✅ **One diplomacy command completed** (ResolveTruceOfferCommand)
+
+**Next Milestones:**
+- ✅ **70% target:** Migrate Tier 1 + some Tier 2 commands **COMPLETED**
+- ✅ **80% target:** Continue with remaining non-diplomacy commands **COMPLETED**
+- **85% target:** Complete API layer migration  
+- **95% target:** Complete diplomacy migration
+
+### 🔄 Conversion Strategy Updates
+
+**Revised Approach Based on Analysis:**
+
+1. **Focus on Core Dependencies First**
+   - Migrate `battalion_type` model (unlocks 2 commands immediately)
+   - Migrate `action_result` model (unlocks 12+ commands)
+   - Migrate `available_command`/`selected_command` (unlocks UI layer)
+
+2. **Leverage Existing Success**
+   - 77.5% of commands already fully migrated
+   - Use migrated commands as reference implementations
+   - Diplomacy helpers prove complex business logic can work with Scala models
+
+3. **Group Related Migrations**
+   - Military commands: `ArmTroopsCommand`, `TrainCommand`, `OrganizeTroopsCommand`
+   - UI commands: All using `available_command`/`selected_command`
+   - Diplomacy commands: All `Resolve*Command` variants

-# OAuth Relay Worker
-
-Cloudflare Worker that relays OAuth callbacks to the eagle0:// custom URL scheme.
-
-## Why?
-
-Discord (and some other OAuth providers) don't support custom URL schemes as redirect URIs. This worker acts as a relay:
-
-1. Discord redirects to `https://eagle0-oauth-relay.<account>.workers.dev/oauth/callback?code=xxx&state=yyy`
-2. Worker responds with 302 redirect to `eagle0://auth/callback?code=xxx&state=yyy`
-3. OS opens the Eagle0 app via deep link
-
-## Deploy
-
-1. Install wrangler: `npm install -g wrangler`
-2. Login: `wrangler login`
-3. Deploy: `wrangler deploy`
-
-The worker will be available at `https://eagle0-oauth-relay.<your-account>.workers.dev`
-
-## Test Locally
-
-```bash
-wrangler dev
-# Then in another terminal:
-curl -I "http://localhost:8787/oauth/callback?code=test&state=abc"
-```
-
-## Test Production
-
-```bash
-curl -I "https://eagle0-oauth-relay.<your-account>.workers.dev/oauth/callback?code=test&state=abc"
-```
-
-Should return:
-```
-HTTP/2 302
-location: eagle0://auth/callback?code=test&state=abc
-```
-
-## OAuth Provider Configuration
-
-In Discord Developer Portal / Google Cloud Console, set the redirect URI to:
-```
-https://eagle0-oauth-relay.<your-account>.workers.dev/oauth/callback
-```

-# Admin Server Enhancement Plan
-
-## Overview
-
-This document outlines enhancements to the Go admin server (`src/main/go/net/eagle0/admin_server/`) to provide a proper web UI for game administration.
-
-### Current State
-
-The admin server provides a full web UI with htmx interactivity:
-- `GET /` - Redirect to games list
-- `GET /games` - Game list page (HTML)
-- `GET /games/{id}` - Game detail with action history
-- `GET /games/{id}/history` - History rows (htmx partial, infinite scroll)
-- `GET /games/{id}/action/{index}` - Action detail (htmx partial)
-- `POST /games/{id}/rewind` - Rewind game to target action
-- `GET /settings` - Settings list with live search
-- `POST /settings/update` - Update setting value
-- `GET /health` - Health check (JSON)
-- `GET /api/games` - JSON API for programmatic access
-- `GET /api/games/{id}/history` - JSON API for history
-
-### Goals
-
-1. **Web UI**: Replace raw JSON with an interactive HTML interface
-2. **Settings Management**: View and modify the 275+ game settings at runtime
-3. **Game Rewind**: Restore a game to a previous action count
-
----
-
-## Architecture
-
-### Technology Choice: Go Templates + htmx
-
-**Rationale:**
-- Single binary deployment (no separate frontend build)
-- htmx provides interactivity without JavaScript framework complexity
-- Familiar HTML/CSS, minimal learning curve
-- Excellent for admin tools where SEO and bundle size don't matter
-
-**Alternatives Considered:**
-- React/Vue SPA: Adds build complexity, separate deployment artifact
-- Server-side only: Less interactive, full page reloads
-

-### Game Detail Page
-
-Shows game info and scrollable action history:
-- **Reverse chronological order**: Most recent actions displayed first
-- Each action shows: index, type, round ID
-- **Clickable actions**: Clicking an action row expands to show JSON representation of the full action data
-- "Rewind to here" button on each action row
-- Infinite scroll loads more history via htmx (loading older actions as user scrolls down)
-
-### Implementation Notes
-
-1. **Embed static files**: Use `//go:embed` to bundle templates and static files
-2. **Template functions**: Add helpers for formatting (hex IDs, timestamps, action summaries)
-3. **CSS framework**: Use Pico CSS (~10KB) for clean defaults without classes
-
----
-
-## Feature 2: Settings Management
-
-### New gRPC Endpoints (Eagle Server)
-
-Add to `eagle.proto`:
-
-```protobuf
-message Setting {
-  string name = 1;
-  string type = 2;           // "Int" or "Double"
-  string value = 3;          // Current value as string
-  string default_value = 4;  // Default from BUILD.bazel
-  string description = 5;    // Optional, for UI hints
-}
-
-message GetSettingsRequest {
-  string filter = 1;         // Optional name filter (substring match)
-}
-
-message GetSettingsResponse {
-  repeated Setting settings = 1;
-}
-
-message UpdateSettingRequest {
-  string name = 1;
-  string value = 2;
-}
-
-message UpdateSettingResponse {
-  Setting setting = 1;       // Updated setting
-  string error = 2;          // Empty on success
-}
-
-service Eagle {
-  // ... existing methods ...
-  rpc GetSettings(GetSettingsRequest) returns (GetSettingsResponse);
-  rpc UpdateSetting(UpdateSettingRequest) returns (UpdateSettingResponse);
-}
-```
-
-### Eagle Server Implementation
-
-Create a settings registry that:
-1. Discovers all `IntSetting` and `DoubleSetting` instances via reflection or explicit registration
-2. Provides get/set by name
-3. Validates types on update
-
-```scala
-// src/main/scala/net/eagle0/eagle/library/settings/SettingsRegistry.scala
-object SettingsRegistry {
-  private val settings: Map[String, Either[IntSetting, DoubleSetting]] = Map(
-    "ActionVigorCost" -> Left(ActionVigorCost),
-    "BaseFoodBuyPrice" -> Right(BaseFoodBuyPrice),
-    // ... register all 275 settings
-  )
-
-  def getAll(filter: Option[String]): Seq[Setting] = ...
-  def get(name: String): Option[Setting] = ...
-  def update(name: String, value: String): Either[String, Setting] = ...
-}
-```
-
-**Alternative: Code generation**
-
-Rather than manually registering 275 settings, modify `setting_rule.bzl` to generate a registry file during build.
-
-### Admin Server Routes
-
-| Route | Method | Description |
-|-------|--------|-------------|
-| `/settings` | GET | Settings list page with search |
-| `/settings/{name}` | GET | Single setting detail (htmx partial) |
-| `/settings/{name}` | PUT | Update setting value |
-| `/api/settings` | GET | JSON API |
-| `/api/settings/{name}` | PUT | JSON API |

-```
-
-### Considerations
-
-1. **Persistence**: Settings changes are in-memory only. Document that restarts reset to defaults.
-2. **Validation**: Validate numeric ranges where applicable (e.g., percentages 0-100)
-3. **Categories**: Consider grouping settings by prefix (AI*, Combat*, Economy*, etc.)
-4. **Audit log**: Log setting changes with timestamp for debugging
-

-
-## Feature 3: Game Rewind
-
-### Concept
-
-Restore a game to a previous point in its action history. This is useful for:
-- Debugging issues that occurred at a specific point
-- Testing "what if" scenarios
-- Recovering from bugs that corrupted state
-
-### New gRPC Endpoint
-
-Add to `eagle.proto`:
-
-```protobuf
-message RewindGameRequest {
-  int64 game_id = 1;
-  int32 target_action_count = 2;  // Rewind to state after this many actions
-}
-
-message RewindGameResponse {
-  bool success = 1;
-  string error = 2;
-  int32 new_action_count = 3;
-  int32 disconnected_clients = 4;  // Number of clients that were disconnected
-}
-
-service Eagle {
-  // ... existing methods ...
-  rpc RewindGame(RewindGameRequest) returns (RewindGameResponse);
-}
-```
-
-### Eagle Server Implementation
-
-The `GameHistory` already stores `ActionWithResultingState` for each action, which includes the `GameState` after that action. Rewinding means:
-
-1. **Validate**: Check that `target_action_count` is within valid range (0 to current count)
-2. **Get target state**: Retrieve `GameState` at target action count from history
-3. **Disconnect clients**: Close all human player connections (they'll need to reconnect)
-4. **Replace engine**: Create new `EngineImpl` with target state and truncated history
-5. **Reset AI state**: Clear any cached AI state that depends on current game state
-
-```scala
-// GameController.scala (pseudocode)
-def rewindTo(targetActionCount: Int): Either[String, RewindResult] = {
-  if (targetActionCount < 0 || targetActionCount > engine.history.count)
-    return Left(s"Invalid action count: $targetActionCount")
-
-  // Get state at target point
-  val targetState = engine.history.stateAt(targetActionCount)
-  val truncatedHistory = engine.history.truncateTo(targetActionCount)
-
-  // Disconnect all human clients
-  val disconnectedCount = humanClients.length
-  humanClients.foreach(_.disconnect("Game rewound by admin"))
-
-  // Create new engine at target state
-  val newEngine = EngineImpl(
-    gameId = engine.gameId,
-    currentState = targetState,
-    history = truncatedHistory,
-    // ... other fields
-  )
-
-  // Replace controller's engine
-  this.engine = newEngine
-
-  Right(RewindResult(targetActionCount, disconnectedCount))
-}
-```
-
-### GameHistory Enhancement
-
-Add method to get state at a specific action count:
-
-```scala
-trait GameHistory {
-  // ... existing methods ...
-
-  def stateAt(actionCount: Int): GameState = {
-    if (actionCount == 0) initialState
-    else all(actionCount - 1).resultingState
-  }
-
-  def truncateTo(actionCount: Int): GameHistory = {
-    GameHistoryImpl(
-      initialState = initialState,
-      actions = all.take(actionCount)
-    )
-  }
-}
-```
-
-### Admin Server Route
-
-| Route | Method | Description |
-|-------|--------|-------------|
-| `/games/{id}/rewind` | POST | Rewind game (form: `target_action_count`) |
-| `/games/{id}/rewind/confirm` | GET | Confirmation modal (htmx partial) |
-
-### Rewind UI Flow
-
-1. User views game history
-2. User clicks "Rewind to here" on an action row
-3. Confirmation modal appears via htmx:
-   ```
-   ┌─────────────────────────────────────────┐
-   │  Rewind Game abc123f?                   │
-   │                                         │
-   │  This will:                             │
-   │  • Restore to action 456 (Round 23)     │
-   │  • Discard 778 subsequent actions       │
-   │  • Disconnect 2 connected players       │
-   │                                         │
-   │  This cannot be undone.                 │
-   │                                         │
-   │            [Cancel]  [Rewind]           │
-   └─────────────────────────────────────────┘
-   ```
-4. On confirm, POST to `/games/{id}/rewind`
-5. Success: redirect to game detail showing new state
-6. Error: show error message
-
-### Safety Considerations
-
-1. **No undo**: Rewinding discards history. Consider optional backup before rewind.
-2. **Client disconnect**: All connected clients are forcibly disconnected.
-3. **AI state**: Ensure AI clients restart cleanly after rewind.
-4. **Concurrent access**: Lock game during rewind to prevent race conditions.
-5. **Authorization**: In production, require admin authentication.

-**Deliverable**: Browsable game list and history in HTML with clickable action details
-
-### Phase 2: Settings Management
-
-**Status: Complete**
-
-1. ✅ Add `GetSettings` to `eagle.proto` (uses existing `AddSettings` for updates)

-
-**Status: Complete**
-
-1. ✅ Add `RewindGame` to `eagle.proto`
-2. ✅ Implement `stateAt` and `truncateTo` in `GameHistory`
-3. ✅ Implement rewind logic in `Engine` and `GameController`

-8. ✅ Add admin server `/games/{id}/rewind` POST handler
-9. ✅ Add success/error feedback UI
-
-**Deliverable**: Rewind games to any previous action
-
-### Phase 4: Polish
-
-**Status: Not Started**
-
-#### High Priority
-1. **Add tests for rewind functionality**
-   - `PersistedHistory.truncateTo` (handles complex persisted vs recent logic)
-   - `InMemoryHistory.truncateTo`
-   - `EngineImpl.rewindTo`
-   - `GameController.rewindTo`
-   - `GamesManager.rewindGame`
-
-2. **Improve action history display**
-   - Human-readable action type names (e.g., "New Round" instead of "NewRoundAction")
-   - Show acting faction/province when available
-   - Action summaries from the `summary` field in `GameHistoryEntry`
-
-#### Medium Priority
-3. **Settings improvements**
-   - Group settings by category prefix (AI*, Combat*, Economy*, etc.)
-   - Show setting descriptions where available
-   - Pagination for large settings lists
-
-4. **Error handling improvements**
-   - Better error messages on failed operations
-   - Retry logic for transient gRPC failures
-
-#### Low Priority (Nice to Have)
-5. **Basic auth** - HTTP Basic Auth or OAuth for production use
-6. **Audit logging** - Log admin actions with timestamps
-7. **Documentation** - Usage guide, deployment notes
-
-#### Future Considerations
-- Game creation from admin UI
-- Player management (view connected players, force disconnect)
-- Export game history to file
-- Metrics/stats dashboard
-
----
-
-## Security Notes
-
-The admin server is intended for local/trusted network use only. For production:
-
-1. **Do not expose to public internet** without authentication
-2. Consider adding HTTP Basic Auth or OAuth
-3. Run on internal network or behind VPN
-4. Log all admin actions for audit trail
-
----
-
-## Open Questions
-
-1. **Settings persistence**: Should we add optional persistence to disk/database?
-2. **Game snapshots**: Should rewind create a backup first?
-3. **Multi-admin**: Need locking if multiple admins access simultaneously?
-4. **Shardok settings**: Are there Shardok (C++) settings to expose too?

-# CommandProto Usage Analysis in shardok/ai
-
-This document analyzes all remaining usages of `CommandProto` (protocol buffer representation) in the AI code and identifies opportunities to eliminate proto conversion by using `ShardokCommand` directly.
-
-## Summary
-
-**Total CommandProto usages found:** 42 locations across 9 files
-
-**Eliminated:** 6 usages (14%) - ✅ **Phase 1 Complete**
-**Can be eliminated:** ~14 usages (33%)
-**Must keep (for now):** ~22 usages (53%)
-
----
-
-## Files with CommandProto Usage
-
-### 1. AICommandFilter.cpp (6 usages) - ✅ **COMPLETED** (PR #4505)
-**Location:** Lines 146, 189, 252, 356, 387, 428
-
-**Original usage:**
-```cpp
-const auto cmdProto = cmd.GetCommandProto();
-if (!cmdProto.has_target()) { ... }
-const auto& targetCoords = cmdProto.target();
-if (!cmdProto.has_actor()) { ... }
-const auto unitId = cmdProto.actor().value();
-```
-
-**Replaced with:**
-```cpp
-const int targetRow = cmd.GetTargetRow();
-const int targetCol = cmd.GetTargetColumn();
-if (targetRow < 0 || targetCol < 0) {
-    throw ShardokInternalErrorException("Command missing required target");
-}
-const Coords targetCoords(targetRow, targetCol);
-
-const int actorId = cmd.GetActorUnitId();
-if (actorId < 0) {
-    throw ShardokInternalErrorException("Command missing required actor");
-}
-```
-
-**Status:** ✅ **ELIMINATED** - Replaced with direct accessors + exception handling
-**Impact:** Eliminated 6 proto conversions in hot path (command filtering)
-**Completed:** Phase 1, PR #4505
-
----
-
-### 2. ShardokAIClient.cpp (8 usages)
-**Location:** Lines 83, 86, 87, 102, 105, 237, 261, 311, 356
-
-**Usage breakdown:**
-
-#### a) Command validation (lines 83-87)
-```cpp
-void CheckCommand(const CommandProto &realDescriptor, const CommandProto &guessedDescriptor) {
-    differencer.IgnoreField(CommandProto::descriptor()->FindFieldByNumber(
-            CommandProto::kFollowUpCommandTypesFieldNumber));
-```
-**Status:** ❌ **MUST KEEP** - Uses protobuf reflection for comparison
-**Reason:** Comparing proto messages for correctness checking requires proto API
-
-#### b) GetAvailableCommandProtos calls (lines 105, 356)
-```cpp
-const auto guessedCommands = guessedEngine.GetAvailableCommandProtos(playerId, false);
-if (const auto &availableCommands = engine.GetAvailableCommandProtos(playerId, false);
-```
-**Status:** ✅ **CAN REPLACE** - Should use `GetAvailableCommandsForAIPlayer()` instead
-**Impact:** This is a major conversion point - converts entire command list to protos
-**Priority:** HIGH (converts all commands to proto unnecessarily)
-
-#### c) Strategy selector methods (lines 102, 237, 261, 311)
-```cpp
-const vector<CommandProto> &realAvailableCommands) const -> CommandChoiceResults
-```
-**Status:** ✅ **CAN REPLACE** - Depends on fixing strategy selector signatures
-**Priority:** MEDIUM (depends on other refactors)
-
----
-
-### 3. IterativeDeepeningAI.cpp/hpp (4 usages)
-**Location:** Lines 41, 272 (cpp), 73, 96 (hpp)
-
-**Current usage:**
-```cpp
-const std::vector<CommandProto>& commands,
-```
-
-**Status:** ✅ **CAN REPLACE** - These methods should accept `CommandListSPtr` instead
-**Impact:** Major - this is the main AI search algorithm
-**Priority:** HIGH (core AI algorithm)
-
-**Note:** IterativeDeepeningAI already receives commands as proto vectors. The conversion happens upstream at the entry point. Need to trace back to find where `GetAvailableCommandProtos` is called.

-
-### 4. AIFleeDecisionCalculator.cpp/hpp (6 usages)
-**Location:** Lines 17, 38, 39, 62, 63 (hpp), 18, 19, 137, 138 (cpp)
-
-**Current usage:**
-```cpp
-const vector<CommandProto>& availableCommands,
-const vector<CommandProto>::const_iterator& fleeCommand,
-```
-
-**Status:** ✅ **CAN REPLACE** - Should use `CommandListSPtr` and indices instead
-**Impact:** Flee decision logic could avoid proto conversion
-**Priority:** MEDIUM
-
----
-
-### 5. AIAttackerStrategySelector.cpp/hpp (2 usages)
-**Location:** Line 30 in both files
-
-**Current usage:**
-```cpp

-**Current implementation:**
-```cpp
-const vector<CommandProto>& /*availableCommands*/) -> AIStrategy {
-    // Parameter is commented out - not used!
-    return AIStrategy::DEFAULT;
-}
-```
-**Priority:** LOW (parameter unused, but signature should be consistent)

-## Key Conversion Points (Entry Points)
-
-### ShardokEngine::GetAvailableCommandProtos()
-This method converts the entire command list from `CommandListSPtr` to `vector<CommandProto>`.
-
-**Current flow:**
-```
-ShardokEngine::GetAvailableCommandsForAIPlayer() → CommandListSPtr
-                ↓ (conversion)
-ShardokEngine::GetAvailableCommandProtos() → vector<CommandProto>
-                ↓
-AI algorithms (IterativeDeepeningAI, etc.)
-```
-
-**Desired flow:**
-```
-ShardokEngine::GetAvailableCommandsForAIPlayer() → CommandListSPtr
-                ↓ (no conversion!)
-AI algorithms use CommandSPtr directly
-```
-
----
-
-## Recommendations by Priority
-
-### HIGH Priority (Performance-critical hot paths)
-
-1. **AICommandFilter.cpp (6 usages)**
-   - Replace `cmd.GetCommandProto()` with direct accessor methods
-   - Use `GetActorUnitId()`, `GetTargetRow()`, `GetTargetColumn()`
-   - Impact: Eliminates 6 proto conversions per filtered command
-
-2. **ShardokAIClient.cpp - GetAvailableCommandProtos calls**
-   - Replace calls to `GetAvailableCommandProtos()` with `GetAvailableCommandsForAIPlayer()`
-   - Impact: Eliminates conversion of entire command list
-
-3. **IterativeDeepeningAI**
-   - Change signature from `vector<CommandProto>` to `CommandListSPtr`
-   - Impact: Main AI search algorithm avoids proto conversion
-
-### MEDIUM Priority
-
-4. **AIFleeDecisionCalculator**
-   - Change to use `CommandListSPtr` and indices
-   - Impact: Flee decision logic avoids proto
-
-5. **ShardokAIClient strategy methods**
-   - Update signatures to use `CommandListSPtr`
-   - Cascades to strategy selectors
-
-### LOW Priority
-
-6. **Type aliases**
-   - Remove unused `using CommandProto` declarations
-   - Clean up imports
-
----
-
-## Migration Strategy
-
-### Phase 1: Low-hanging fruit (AICommandFilter) - ✅ **COMPLETED** (PR #4505)
-- ✅ Replaced 6 proto conversions with direct accessor calls
-- ✅ Added exception handling for missing actor/target data
-- ✅ No signature changes needed
-- ✅ Immediate performance benefit
-- **PR:** #4505
-
-### Phase 2: Entry point (ShardokAIClient)
-- Replace `GetAvailableCommandProtos()` calls with `GetAvailableCommandsForAIPlayer()`
-- Update method signatures in ShardokAIClient
-
-### Phase 3: Core AI (IterativeDeepeningAI)
-- Change IterativeDeepeningAI to accept `CommandListSPtr`
-- This is the biggest change but has highest impact
-
-### Phase 4: Supporting systems
-- Update AIFleeDecisionCalculator
-- Update strategy selectors
-- Clean up type aliases
-
-### Phase 5: Validation code
-- Keep proto-based validation as-is (uses reflection)
-- Consider if validation is still needed in production
-
----
-
-## Notes
-
-- **MCTS already converted**: The MCTS code path already uses `CommandListSPtr` directly
-- **Proto still needed**: For serialization/network communication (not in AI hot path)
-- **Validation**: Proto comparison in CheckCommand() should remain (uses proto reflection)
-
----
-
-## Estimated Impact
-

-# Deproto Migration Plan
-
-## Vision
-
-**Protocol buffers should only be used at the edges** — for network serialization (gRPC) and disk persistence. Inside the Eagle game engine, all logic should operate on native Scala models.

-## Current State
-
-### Completed Phases
-
-| Phase | Status | Summary |
-|-------|--------|---------|
-| Phase 1: GameStateC | **Complete** | Scala `GameState` model with 22 fields |
-| Phase 2: EngineImpl | **Complete** | Holds Scala `GameState` internally |
-| Phase 3: GameHistory | **Complete** | `stateAfter` returns Scala GameState |
-| Phase 4: ActionResultT | **Complete** | All 59 actions return `ActionResultT` |
-| Phase 5: Action Base Classes | **Complete** | All `RandomSequentialResultsAction` and `DeterministicSingleResultAction` converted to T-type base classes |
-| Phase 5b: Base Class Cleanup | **Complete** | `RandomSequentialResultsAction` and `DeterministicSingleResultAction` deleted |
-| Phase 5c: RoundPhaseAdvancer Actions | **Complete** | All actions called by RoundPhaseAdvancer accept Scala GameState |
-| Phase 5d: RoundPhaseAdvancer Itself | **Complete** | RoundPhaseAdvancer.checkForPhaseAdvancement takes Scala GameState |
-
-### Phase 5c/5d Progress (Complete)
-
-`RoundPhaseAdvancer.checkForPhaseAdvancement` now accepts Scala `GameState` and `ActionResultApplier` directly (PR #4677).
-
-| Action | PR | Status |
-|--------|-----|--------|
-| `PrisonerExchangeAction` | #4670 | ✅ Merged |
-| `PerformForcedTurnBackAction` | #4671 | ✅ Merged |
-| `PerformHeroDeparturesAction` | #4672 | ✅ Merged |
-| `RequestFreeForAllBattlesAction` | #4673 | ✅ Merged |
-| `EndPlayerCommandsPhaseAction` | #4674 | ✅ Merged |
-| `EndDiplomacyResolutionPhaseAction` | #4675 | ✅ Merged |
-| `RoundPhaseAdvancer` itself | #4677 | ✅ Merged |
-
-### EngineImpl Progress
-
-| Change | PR | Status |
-|--------|-----|--------|
-| `recursiveTransform` deleted | #4677 | ✅ Merged |
-| `recursiveTransformT` uses `RandomStateTSequencer` | #4677 | ✅ Merged |
-
-### Current Architecture
-
-**ActionResultT Production (100% Complete):**
-- All actions produce `ActionResultT`
-- Conversion to `ActionResultProto` happens via `ActionResultProtoConverter.toProto()`
-- No direct `ActionResultProto` construction outside the converter
-
-**ActionResultProto Consumption (Next Target):**
-- `ActionResultProtoApplierImpl` - applies proto results to proto GameState
-- `RoundPhaseAdvancer` - calls converter, passes protos to applier
-- `InMemoryHistory` / `PersistedHistory` - stores proto results
-- Service layer (`GameController`, `GamesManager`, etc.) - uses proto for client communication
-
----
-
-## Phase 6: Migrate to ActionResultT Consumers
-
-### Objective
-
-Eliminate internal consumption of `ActionResultProto`. Everything inside the engine should work with `ActionResultT`.
-
-### Current Flow (Proto-Heavy)
-```
-Action.execute()
-    → ActionResultT
-    → ActionResultProtoConverter.toProto()
-    → ActionResultProto
-    → ActionResultProtoApplierImpl.applyActionResults()
-    → GameStateProto
-    → GameStateConverter.fromProto()
-    → GameStateC
-```
-
-### Target Flow (T-Types Throughout)
-```
-Action.execute()
-    → ActionResultT
-    → ActionResultApplier.applyActionResults()
-    → GameStateC
-
-    (Proto conversion only at boundaries)
-```
-
-### Key Files to Convert
-
-**Tier 1 - Core Applier:** ✅ **Complete**
-```
-src/main/scala/net/eagle0/eagle/library/actions/applier/ActionResultApplierImpl.scala
-```
-`ActionResultApplier` applies `ActionResultT` directly to Scala `GameState`. The legacy `ActionResultTApplierImpl` wraps it and converts to/from proto for callers that still need proto types.
-
-**Tier 2 - RoundPhaseAdvancer:** ✅ **Complete**
-```
-src/main/scala/net/eagle0/eagle/library/RoundPhaseAdvancer.scala
-```
-Now accepts Scala `GameState` and `ActionResultApplier`. Only converts to proto lazily for `AvailableCommandsFactory` calls.
-
-**Tier 3 - Sequencers:**
-```
-src/main/scala/net/eagle0/eagle/library/actions/impl/common/RandomStateTSequencer.scala
-src/main/scala/net/eagle0/eagle/library/actions/impl/common/RandomStateProtoSequencer.scala
-```
-Modify `RandomStateTSequencer` to thread Scala `GameState` throughout (currently converts to proto internally). Then evaluate whether `RandomStateProtoSequencer` is still needed at all.
-
-**Current State**: `RandomStateTSequencer` accepts Scala `GameState` via its `apply()` method but internally converts to proto. All callback methods (`withRandomActionResult`, `withActionResults`, etc.) pass `GameStateProto` to callers, forcing actions that use the sequencer to work with proto types internally.
-
-**Target State**: Create a fully protoless sequencer where:
-1. `lastState` returns Scala `GameState` (not `lastStateProto`)
-2. All callback methods pass Scala `GameState` to callers
-3. Actions using the sequencer can be fully protoless
-
-**Migration Path**:
-1. Add `lastState: GameState` method alongside `lastStateProto` (non-breaking)
-2. Add parallel callback methods that pass Scala GameState (e.g., `withScalaActionResult`)
-3. Migrate actions one by one to use the new Scala-based callbacks
-4. Once all actions migrated, deprecate/remove proto-based callbacks
-5. Remove `lastStateProto` once no longer used
-
-**RandomStateSequencer Migration Progress** (PR #4679 introduced protoless `RandomStateSequencer`):
-
-| Action | Status |
-|--------|--------|
-| `TruceTurnBackPhaseAction` | ✅ Migrated (PR #4680) |
-| `EndHandleRiotsPhaseAction` | ✅ Migrated (PR #4684) |
-| `PerformVassalCommandsPhaseAction` | ✅ Migrated |
-| `PerformVassalDefenseDecisionsAction` | ✅ Migrated |
-| `EndVassalCommandsPhaseAction` | ✅ Migrated |
-| `PerformReconResolutionAction` | ✅ Migrated |
-| `NewRoundAction` | ✅ Migrated (PR #4698) |
-| `EndBattleAftermathPhaseAction` | ✅ Migrated (PR #4699) |
-| `EndDiplomacyResolutionPhaseAction` | ✅ Migrated |
-| `PerformUnaffiliatedHeroesAction` | ✅ Migrated |
-| `EngineImpl.recursiveTransformT` | ✅ Migrated (PR #4704) |
-| `ProtolessSequentialResultsActionWrapper` | ✅ Migrated (PR #4705) |
-| `LegacyRandomStateTSequencer` | ✅ **Deleted** (PR #4705) |
-
-**TCommandFactory Extraction** (PR #4684):
-
-To enable lightweight mocking of command creation in tests, `TCommandFactory` trait was extracted from `CommandFactory`. This allows tests to mock just the `makeTCommand` method without pulling in all 40+ command dependencies that `CommandFactory` requires.
-
-- `TCommandFactory` - lightweight trait with just `makeTCommand`
-- `CommandFactory extends TCommandFactory` - maintains backward compatibility
-- Actions accepting command factories now use `TCommandFactory` type for better testability
-
-**Tier 4 - History APIs:**
-```
-src/main/scala/net/eagle0/eagle/service/InMemoryHistory.scala
-src/main/scala/net/eagle0/eagle/service/PersistedHistory.scala
-```
-Change APIs to vend Scala `GameState` and `ActionResultT` instead of proto versions. `PersistedHistory` converts to proto internally for disk persistence; `InMemoryHistory` doesn't need proto at all.
-
-### ActionResultProto Consumer Inventory
-
-| File | Usage | Status |
-|------|-------|--------|
-| `ActionResultApplierImpl.scala` | Applies ActionResultT to Scala GameState | ✅ **Complete** |
-| `ActionResultTApplierImpl.scala` | Legacy wrapper - converts to/from proto | Keep until all callers migrated |
-| `RoundPhaseAdvancer.scala` | Uses Scala GameState | ✅ **Complete** |
-| `RandomStateSequencer.scala` | Threads Scala GameState | ✅ **Complete** |
-| `VigorXPApplier.scala` | Has both proto and Scala methods | Scala method exists, delete proto method when unused |
-| `PerformForcedTurnBackAction.scala` | Fully protoless | ✅ **Complete** |
-| `ResolveBattleAction.scala` | Heavy proto usage | Blocked by proto dependencies |
-| `InMemoryHistory.scala` | Stores proto results | Pending - vend Scala types |
-| `PersistedHistory.scala` | Stores proto results | Pending - vend Scala types, convert for disk |
-| `GameController.scala` | Uses proto for client communication | Keep proto (gRPC boundary) |
-
-### Remaining Proto Usage in Actions
-
-**Progress: 47 of 52 action files (90%) are fully protoless.**
-
-The following 5 actions still have proto usage:
-
-| Action | Proto Usages | Blocker | Effort |
-|--------|--------------|---------|--------|
-| `ResolveBattleAction` | 24 | Shardok interface, complex battle logic | High |
-| `PerformVassalCommandsPhaseAction` | 3 | `CommandChoiceHelpers` takes proto GameState | Medium |
-| `EndHandleRiotsPhaseAction` | 2 | `CommandChoiceHelpers` takes proto GameState | Medium |
-| `PerformVassalDefenseDecisionsAction` | 2 | `CommandChoiceHelpers` takes proto GameState | Medium |
-| `EndVassalCommandsPhaseAction` | 1 | `CommandChoiceHelpers` takes proto GameState | Medium |
-
-**Note:** `NewRoundAction` is now fully protoless after converting `ChronicleEventGenerator` to return Scala `ChronicleEvent` types directly.
-
-**Deleted Dead Code:**
-- `UnaffiliatedHeroMovedAction` - Was never called; `PerformUnaffiliatedHeroesAction.heroMovedResult` constructs `ActionResultC` directly
-- `HeroBackstoryUpdateActionGenerator.fromGameState` - Dead method that converted proto to Scala; only `apply(GameState)` is used
-
-**Note**: `PerformReconResolutionAction` and `EndBattleAftermathPhaseAction` are now fully protoless after:
-1. Migrating `FactionT.reconnedProvinces` and `ChangedFactionC.updatedReconnedProvinces` to use Scala `ProvinceView`
-2. Adding Scala overload of `ProvinceViewFilter.withdrawnFromProvinceView`
-
-### Estimated Effort (Remaining)
-
-| Component | Lines | Complexity | Blocks |
-|-----------|-------|------------|--------|
-| `CommandChoiceHelpers` to Scala | ~2000 | High | 4 vassal actions |
-| `ResolveBattleAction` refactor | ~500 | High | 1 action (complex) |
-| History API updates | ~100 | Low | - |
-| **Total Remaining** | **~2600** | | |
-
-**Completed:**
-- `ChronicleEventGenerator` converted to return Scala `ChronicleEvent` types directly
-
-### CommandChoiceHelpers Migration Status
-
-Several command selectors have already been converted to use Scala types:
-
-| File | Status | Notes |
-|------|--------|-------|
-| `AttackCommandChooser.scala` | ✅ **Protoless** | Uses Scala `GameState`, `HeroT`, `ProvinceT` |
-| `AlmsCommandSelector.scala` | ✅ **Protoless** | Uses Scala `GameState`, `HeroT`, `ProvinceT` |
-| `FoodConsumptionUtils.scala` | ✅ **Protoless** | Uses Scala `GameState`, `ProvinceT`, `RoundPhase` |
-| `MarchSuppliesHelpers.scala` | ✅ **Protoless** | Uses `BattalionT` |
-| `CombatUnitSelector.scala` | ✅ **Protoless** | Uses `HeroT`, `BattalionT`, `BattalionType` |
-| `ExpandCommandSelector.scala` | ✅ **Protoless** | Uses Scala `GameState`, `ProvinceT`, `FactionT` |
-| `ImproveCommandSelector.scala` | ✅ **Protoless** | Uses Scala `GameState`, `ProvinceT`, `HeroT` |
-| `OrganizeCommandSelector.scala` | ✅ **Protoless** | Uses Scala `GameState`, `BattalionT`, `BattalionType` |
-| `RansomOfferHelpers.scala` | ✅ **Protoless** | Uses Scala `GameState`, `FactionT` |
-| `CommandChoiceHelpers.scala` | ❌ Proto | Main entry point, converts to Scala when calling converted selectors |
-| `ProvinceGoldSurplusCalculator.scala` | **Partial** | Has both Scala and proto overloads |
-| Other selectors | ❌ Proto | Various proto dependencies |
-
-**Pattern**: `CommandChoiceHelpers` currently uses `GameStateConverter.fromProto(gameState)` when calling already-converted selectors like `AlmsCommandSelector` and `AttackCommandChooser`. This allows incremental migration.
-
-**Next Steps**:
-1. ~~Convert `ExpandCommandSelector` to Scala types~~ ✅ Done
-2. ~~Convert `ImproveCommandSelector` to Scala types~~ ✅ Done
-3. ~~Convert `OrganizeCommandSelector` to Scala types~~ ✅ Done (PR #4812)
-4. ~~Convert `RansomOfferHelpers` to Scala types~~ ✅ Done (PR #4821)
-5. Convert remaining selectors one at a time
-6. Update `CommandChoiceHelpers` to accept Scala `GameState` once all selectors are converted
-
-### Progress Summary
-
-| Metric | Value |
-|--------|-------|
-| Action files fully protoless | 47 / 52 (90%) |
-| Proto usages in remaining actions | 32 total |
-| Biggest blocker | `ResolveBattleAction` (24 usages) |
-| Second biggest blocker | `CommandChoiceHelpers` (blocks 4 actions) |
-
-### Validation
-- [x] `ActionResultApplier` created and tested
-- [x] `RandomStateSequencer` threads Scala GameState throughout
-- [x] `RoundPhaseAdvancer` uses T-types internally
-- [x] `ProvinceViewFilter` has Scala overload for server-side use (PR #4752)
-- [x] `FactionT.reconnedProvinces` and `ChangedFactionC.updatedReconnedProvinces` use Scala `ProvinceView`
-- [x] `ProvinceViewFilter.withdrawnFromProvinceView` has Scala overload
-- [ ] `ProvinceViewFilter` faction-filtered views use Scala types
-- [ ] `CommandChoiceHelpers` uses Scala types
-- [ ] History APIs vend Scala types
-- [ ] No `ActionResultProtoConverter.toProto()` calls except at persistence/gRPC boundaries
-- [ ] All tests pass
-
----
-
-## Phase 7: Clean Up Legacy Utilities
-
-### Objective
-Remove remaining direct proto imports from utility classes.
-
-### Files to Modify
-
-| File | Status |
-|------|--------|
-| `CommandChoiceHelpers.scala` | Accepts proto `GameState`; blocks full deproto of `PerformVassalCommandsPhaseAction` and `PerformVassalDefenseDecisionsAction` |
-| `LegacyProvinceUtils.scala` | Replace with `ProvinceUtils.scala` - `hasImminentRiot` added (PR #4683) |
-| `LegacyFactionUtils.scala` | Replace proto imports with `FactionT` |
-| `LegacyUnaffiliatedHeroUtils.scala` | Replace proto imports with Scala models |
-| `BattalionTypeLoader.scala` | Keep proto for file loading, convert immediately after |
-| `BeastUtils.scala` | **Complete** - now uses Scala `BeastInfo` only |
-
-### View Filters (Partially Complete)
-
-The view filter utilities now have Scala overloads for server-side use:
-
-| File | Status | Notes |
-|------|--------|-------|
-| `ProvinceViewFilter.scala` | **Partial** | `filteredProvinceView(ProvinceT, ScalaGameState)` added (PR #4752) |
-| `ArmyFilter.scala` | **Partial** | `filterArmy(ScalaArmy, Map[BattalionId, BattalionT], Option[FactionId])` added |
-| `BattalionViewFilter.scala` | **Complete** | Uses Scala `BattalionT` throughout |
-| `GameStateViewFilter.scala` | Pending | Uses proto types throughout |
-| `GameStateViewDiffer.scala` | Pending | Works with view protos |
-
-**Unblocked Actions** (PR #4752):
-- `EndBattleAftermathPhaseAction` - can now use `filteredProvinceView(province, scalaGameState)`
-- `PerformReconResolutionAction` - can now use Scala overload
-- `GameStateFactionExtensions` - can now use `updatedReconnedProvinces` with Scala types
-
-**Remaining Work**:
-- Faction-filtered `filteredProvinceView(Province, GameState, FactionId)` still uses proto types
-- `withdrawnFromProvinceView` still uses proto types
-- These are needed for client-facing views with visibility restrictions
-
----
-
-## Phase 8: Verify Boundaries
-
-### Objective
-Confirm protos are used correctly at boundaries — and ONLY there.
-
-### Expected Proto Usage (Keep)
-- `EagleServiceImpl.scala` - gRPC boundary
-- `InMemoryHistory.scala` / `PersistedHistory.scala` - Persistence boundary
-- `*Converter.scala` - Explicit conversion utilities
-- `*Loader.scala` - File loading utilities
-
-### Expected No Proto Usage (Verify)
-- `/library/actions/impl/` - Pure Scala models
-- `/library/util/` - Pure Scala models (except loaders)
-- `/model/state/` - Pure Scala models
-
----
-
-## Open Questions
-
-1. **Persistence Format**: Currently game state is persisted as proto. Should we keep proto for persistence (good for schema evolution) or switch to a different format?
-
-2. **Shardok Integration**: `ResolveBattleAction` communicates with Shardok. Should the Shardok interface use protos (external service) or Scala models?
-
-3. **View Generation**: `GameStateViewDiffer` works with view protos for client updates. Views need Scala models (`ProvinceViewT`, etc.) to allow actions like `EndBattleAftermathPhaseAction` to be fully protoless. The Scala views would be converted to proto only at the gRPC boundary when sending updates to clients.
-
----
-
-## Success Criteria
-
-### Code Quality
-- [ ] Zero proto imports in `/library/actions/` (except boundaries)
-- [ ] Zero proto imports in `/library/` utilities (except loaders)
-- [ ] `GameStateT` used throughout engine internals
-- [ ] Proto usage limited to: `EagleServiceImpl`, loaders, converters, persistence
-
-### Architecture
-- [ ] Clear separation: Scala models (internal) vs Proto (boundaries)
-- [ ] Converters as the only bridge between domains
-- [ ] No "proto creep" into business logic

-## Overview
-
-Replace HTTP Basic Auth with OAuth 2.0 (Discord + Google) for Eagle0. Users authenticate via system browser, receive JWT tokens, and choose their own display names.

-
-## Key Design Decisions
-
-| Decision | Choice | Rationale |
-|----------|--------|-----------|
-| OAuth flow | System browser + deep link | Secure, supports password managers |
-| Code exchange | Eagle server directly | No separate auth service needed |
-| JWT signing | RS256 (asymmetric) | Future flexibility for token verification |
-| User storage | Protobuf file via Persister | Consistent with existing patterns |
-| Token expiry | 7-day access, 30-day refresh | Balance security and gaming UX |
-
-## Implementation Phases
-
-### Phase 1: Proto Definitions & Infrastructure
-
-**New files:**
-- `src/main/protobuf/net/eagle0/eagle/api/auth.proto` - Auth API messages
-- `src/main/protobuf/net/eagle0/eagle/internal/user.proto` - User storage schema
-
-**Key proto messages:**
-```protobuf
-// API
-GetOAuthUrlRequest/Response     // Get OAuth URL to open in browser
-ExchangeCodeRequest/Response    // Exchange auth code for JWT
-SetDisplayNameRequest/Response  // Set user's display name
-RefreshTokenRequest/Response    // Refresh expired access token
-
-// Internal storage
-User                           // user_id, display_name, oauth_identities
-UserDatabase                   // All users + indexes for lookup
-```
-
-### Phase 2: Eagle Server Auth Services
-
-**New Scala files:**
-- `src/main/scala/net/eagle0/eagle/auth/OAuthConfig.scala` - Discord/Google config from env vars
-- `src/main/scala/net/eagle0/eagle/auth/JwtService.scala` - JWT creation/validation (RS256)
-- `src/main/scala/net/eagle0/eagle/auth/UserService.scala` - User CRUD, display name validation
-- `src/main/scala/net/eagle0/eagle/auth/OAuthService.scala` - OAuth code exchange
-- `src/main/scala/net/eagle0/eagle/service/AuthServiceImpl.scala` - gRPC service implementation
-
-**Modify:**
-- `src/main/scala/net/eagle0/eagle/service/AuthorizationInterceptor.scala`
-  - Replace Basic Auth parsing with JWT validation
-  - Skip auth for public endpoints (GetOAuthUrl, ExchangeCode, RefreshToken)
-- `src/main/scala/net/eagle0/eagle/service/AuthorizationUtils.scala`
-  - Change context keys from `userName` to `userId` + `displayName`
-- `src/main/scala/net/eagle0/eagle/service/Main.scala`
-  - Wire up new auth services and JWT key loading
-
-### Phase 3: Unity Client OAuth Flow
-
-**New C# files:**
-- `Assets/Auth/OAuthManager.cs` - OAuth flow + deep link handling
-- `Assets/Auth/TokenStorage.cs` - Secure token persistence
-- `Assets/Auth/AuthClient.cs` - gRPC client for auth service
-
-**Modify:**
-- `Assets/EagleConnection.cs`
-  - Replace `AuthInterceptor` (Basic Auth) with `JwtAuthInterceptor` (Bearer token)
-- `Assets/ConnectionHandler/ConnectionHandler.cs`
-  - Replace username/password UI with Discord/Google login buttons
-  - Add display name setup flow for new users
-
-### Phase 4: Platform Configuration
-
-**Deep link registration:**
-- iOS: Add `eagle0://` to CFBundleURLSchemes in Info.plist
-- Android: Add intent-filter for `eagle0://auth` in AndroidManifest.xml
-- Desktop: Register URL scheme (Windows registry / macOS plist)
-
-**OAuth provider setup:**
-1. Discord Developer Portal: Create app, add redirect URI `eagle0://auth/callback`
-2. Google Cloud Console: Create OAuth client, add redirect URI
-
-**Environment variables (server):**
-```

-- Full OAuth flow with mock provider
-- JWT validation in AuthorizationInterceptor
-- gRPC calls with valid/invalid tokens
-
-**Manual testing:**
-- [ ] Discord login (Windows, macOS)

-## Files Summary
-
-### Create
-| File | Purpose |
-|------|---------|
-| `src/main/protobuf/net/eagle0/eagle/api/auth.proto` | Auth API definitions |
-| `src/main/protobuf/net/eagle0/eagle/internal/user.proto` | User storage schema |
-| `src/main/scala/net/eagle0/eagle/auth/OAuthConfig.scala` | Provider config |
-| `src/main/scala/net/eagle0/eagle/auth/JwtService.scala` | JWT handling |
-| `src/main/scala/net/eagle0/eagle/auth/UserService.scala` | User management |
-| `src/main/scala/net/eagle0/eagle/auth/OAuthService.scala` | OAuth flow |
-| `src/main/scala/net/eagle0/eagle/service/AuthServiceImpl.scala` | gRPC service |
-| `Assets/Auth/OAuthManager.cs` | Unity OAuth manager |
-| `Assets/Auth/TokenStorage.cs` | Token storage |
-| `Assets/Auth/AuthClient.cs` | Auth gRPC client |
-
-### Modify
-| File | Changes |
-|------|---------|
-| `AuthorizationInterceptor.scala` | Basic Auth -> JWT validation |
-| `AuthorizationUtils.scala` | userName -> userId + displayName |
-| `Main.scala` | Wire auth services |
-| `EagleConnection.cs` | AuthInterceptor -> JwtAuthInterceptor |
-| `ConnectionHandler.cs` | Login UI -> OAuth buttons + display name |
-
-### Delete
-- nginx htpasswd configuration (no longer needed)
-
-## Security Considerations
-
-1. **State parameter** - CSRF protection in OAuth flow
-2. **PKCE** - Consider adding for mobile (enhancement)
-3. **Secure storage** - Use Keychain (iOS) / Keystore (Android) for tokens
-4. **Token refresh** - 7-day access tokens with 30-day refresh
-5. **Rate limiting** - Limit login attempts per IP
-
-## Dependencies to Add
-
-**Scala (MODULE.bazel):**
-- JWT library (e.g., `jwt-scala` or `nimbus-jose-jwt`)
-- HTTP client (e.g., `sttp` for OAuth requests)
-
-**Unity:**
-- Deep linking is built-in (Unity 2021+)
-- No additional packages required
-
-## Rollback Plan
-
-Keep Basic Auth code in a feature branch. Both auth methods can coexist during transition via feature flag if needed.

-# Actions and Commands Model Usage Analysis
-
-This document analyzes all actions and commands in `src/main/scala/net/eagle0/eagle/library/actions/impl` to determine which use Scala models vs protobuf models, based on BUILD.bazel dependencies.
-
-**Legend:**
-- ✅ **Scala Models Only** - Uses only `//src/main/scala/net/eagle0/eagle/model` dependencies
-- ❌ **Uses Protobuf** - Has dependencies on `//src/main/protobuf` targets
-- 🔄 **Partial Conversion** - Conversion attempted but blocked by dependencies
-
-## Summary
-
-Based on BUILD.bazel dependency analysis (2025-09-16, updated 2025-09-17):
-- **Total Commands Analyzed:** 41
-- **Commands Fully Migrated (No Protobuf):** 41 (100%) ✅
-- **Commands Still Using Protobuf:** 0 (0%) ✅
-- **Total Actions Analyzed:** 48
-- **Actions Fully Migrated (No Protobuf):** 5 (10.4%)
-- **Actions Partially Migrated:** 19 (39.6%)
-- **Actions Still Using Protobuf:** 24 (50%)
-- **Base Classes:** 8 protoless variants available, 6 still use protobuf
-- **Shared Components:** `ResolvedEagleUnit` migrated to use `Option[BattalionT]` for proper null handling
-
-## Conversion Insights
-
-Based on conversion attempt of `ResolveTruceOfferCommand` (see [PR #4379](https://github.com/nolen777/eagle0/pull/4379)):
-
-### Key Challenges Discovered
-
-1. **LLM Integration Dependencies**: Commands that use `DiplomacyResolutionLlmRequestGenerator` face challenges because the LLM system still expects protobuf enum types, not Scala model enums.
-
-2. **Inconsistent Package Naming**: Some files have inconsistent package declarations vs BUILD file locations (e.g., `generated_text_request_generators` in package vs `llm_request_generators` in BUILD).
-
-3. **Model Constructor Differences**: Scala model constructors (e.g., `TruceOffer`) have different required parameters than their protobuf counterparts, requiring more complex data mapping.
-
-4. **Type System Complexity**: Union types and type constraints become more complex when mixing protobuf and Scala model types during transition.
-
-5. **Cascading Dependency Issues**: Converting to `ActionResultC` requires extensive trait dependencies (`ChangedBattalionT`, `ChangedHeroT`, `GeneratedTextRequestT`, etc.) that create complex BUILD dependency graphs, unlike simple protobuf `ActionResult`.
-
-6. **BUILD Complexity**: Each Scala model conversion requires significantly more BUILD dependencies than protobuf equivalents, making incremental conversion difficult.
-
-7. **Build Verification Critical**: Any conversion must maintain working build state - even simple commands like `DefendCommand` can break main server build due to dependency cascades.
-### Successful Conversion Elements
-
-- ✅ Base class conversion (`SimpleAction` → `ProtolessSimpleAction`)
-- ✅ Import updates for most Scala model types
-- ✅ BUILD.bazel dependency updates for core action result types
-- ✅ Basic type conversions for simple cases
-
-### Recommended Conversion Strategy
-
-1. **Architecture-First Approach**: Convert base infrastructure (LLM generators, action result builders) before individual commands
-2. **Wrapper Pattern**: Use existing `Protoless*ActionWrapper` classes as templates for gradual transition
-3. **Dependency Analysis**: Map full dependency trees before attempting conversions to avoid cascading build failures
-4. **Batch Conversions**: Convert related commands together to minimize dependency conflicts
-5. **Build Verification**: **ALWAYS** verify `//src/main/scala/net/eagle0/eagle:eagle_server` and test suite build before creating PRs
-
-### Conversion Requirements
-
-**Before creating any PR:**
-- ✅ `bazel build //src/main/scala/net/eagle0/eagle:eagle_server` succeeds
-- ✅ `bazel test //src/test/scala/... --keep_going` passes (or doesn't introduce new failures)
-- ✅ All BUILD dependencies are correctly specified
-- ✅ Scalafmt and other linters pass

-## Migration Priority Analysis
-
-Based on the BUILD.bazel dependency analysis, here are the key findings and recommendations:
-
-### 🎯 High Impact Migration Targets
-
-**Core Dependencies Blocking Multiple Commands:**
-
-1. **`action_result_scala_proto`** - Used by 12+ commands
-   - Blocks: `DefendCommand`, `FreeForAllDecisionCommand`, diplomacy resolvers
-   - Impact: Would unlock many command migrations
-
-2. **`available_command_scala_proto` / `selected_command_scala_proto`** - Used by 10+ commands
-   - Blocks: All UI-interactive commands
-   - Impact: Would enable client-server interaction model migration
-
-3. **`game_state_scala_proto`** - Used by 8+ commands
-   - Blocks: Complex state-dependent commands
-   - Impact: Core state representation migration
-
-### 📊 Migration Tiers by Complexity
-
-**Tier 1 - Quick Wins (2 commands):**
-- `ArmTroopsCommand` - Only `battalion_type` dependency
-- `TrainCommand` - Only `battalion_type` dependency
-- **Effort:** Low, **Impact:** Demonstrates battalion model usage
-
-**Tier 2 - API Layer (5 commands):**
-- Commands blocked by `available_command`/`selected_command`
-- **Effort:** Medium, **Impact:** High (enables UI interaction models)
-
-**Tier 3 - Diplomacy Suite (6 commands):**
-- All `Resolve*Command` diplomacy commands
-- **Effort:** High, **Impact:** High (complete diplomacy model migration)
-- **Strategy:** Migrate as a group after diplomacy models are ready
-
-### 🏆 Success Metrics
-
-**Current Status:**
-- ✅ **100% of commands fully migrated** (41/41) 🎉
-- ✅ **All diplomacy helpers use Scala models**
-- ✅ **All protoless base classes available**
-- ✅ **ALL command migration completed**
-
-**Completed Milestones:**
-- ✅ **70% target:** Migrate Tier 1 + some Tier 2 commands **COMPLETED**
-- ✅ **80% target:** Continue with remaining non-diplomacy commands **COMPLETED**
-- ✅ **85% target:** Complete API layer migration **COMPLETED**
-- ✅ **95% target:** Complete diplomacy migration **COMPLETED**
-- ✅ **100% target:** Migrate final remaining command (FreeForAllDecisionCommand) **COMPLETED**
-
-### 🎯 Action Migration Progress
-
-**Migration Statistics:**
-- 5/48 Actions fully migrated (10.4%)
-- 20/48 Actions using protoless base classes but with protobuf dependencies (41.7%)
-- 24/48 Actions still fully on protobuf (50%)
-
-**Successfully Migrated Actions:**
-1. **HeroBackstoryUpdateAction** - LLM integration for hero backstories
-2. **ProvinceConqueredAction** - Component-based design with prisoner handling and province conquest
-3. **ProvinceHeldAction** - Component-based design pattern (gameId, currentRoundId, specific models)
-4. **UnaffiliatedHeroAppearedAction** - Hero appearance with name generation
-5. **WithdrawnArmiesReturnHomeAction** - Army withdrawal mechanics
-
-**Recent Migration Updates (2025-09-17):**
-- **ResolvedEagleUnit** - Changed `battalion: BattalionT` to `battalion: Option[BattalionT]`
-  - Properly handles units without battalions (battalion ID -1)
-  - Updated `ShardokInterfaceGrpcClient` to check for `defaultBattalionId` and use `None`
-  - Updated `ResolveBattleAction`, `ProvinceConqueredAction`, `RequestBattlesAction`
-  - All tests updated to handle optional battalions
-
-**Key Migration Patterns:**
-- ✅ Use specific components instead of full GameState (see ProvinceHeldAction, ProvinceConqueredAction)
-- ✅ Convert protobuf models to Scala models at Action boundaries
-- ✅ Update BUILD.bazel to remove protobuf dependencies
-- ✅ Update all call sites and tests
-- ✅ Use `Option[T]` for optional fields instead of special sentinel values (e.g., battalion ID -1)
-
-**Next Migration Candidates (Simple Actions with Protoless Base):**
-1. **FreeForAllDrawAction** - Already uses ProtolessSimpleAction
-2. **FriendlyMoveAction** - Already uses ProtolessSimpleAction
-3. **ShipmentArrivedAction** - Already uses ProtolessSimpleAction
-4. **WonFreeForAllAction** - Already uses ProtolessSimpleAction
-5. **ProvinceConqueredAction** - Already uses ProtolessSimpleAction, only needs `common_unit` migration
-
-### 🔄 Conversion Strategy Updates
-
-**Revised Approach Based on Analysis:**
-
-1. **Focus on Core Dependencies First**
-   - Migrate `battalion_type` model (unlocks 2 commands immediately)
-   - Migrate `action_result` model (unlocks 12+ commands)
-   - Migrate `available_command`/`selected_command` (unlocks UI layer)
-
-2. **Leverage Existing Success**
-   - 77.5% of commands already fully migrated
-   - Use migrated commands as reference implementations
-   - Diplomacy helpers prove complex business logic can work with Scala models
-
-3. **Group Related Migrations**
-   - Military commands: `ArmTroopsCommand`, `TrainCommand`, `OrganizeTroopsCommand`
-   - UI commands: All using `available_command`/`selected_command`
-   - Diplomacy commands: All `Resolve*Command` variants

-# Generates a weekly changelog from merged PRs, uses Claude to create a synopsis,
-# and sends an HTML email via Fastmail JMAP API.
-#
-# Usage: ./scripts/generate_changelog.sh [--dry-run]
-#
-# Configuration files (in ~/.config/eagle0/):
-#   fastmail_token      - API token (required)
-#   changelog_recipient - Email addresses, one per line (optional, defaults to sender)
-#
-# To set up:
-#   mkdir -p ~/.config/eagle0
-#   echo 'your-token' > ~/.config/eagle0/fastmail_token
-#   chmod 600 ~/.config/eagle0/fastmail_token
-#
-#   # Optional: configure recipients (one per line, # for comments)
-#   cat > ~/.config/eagle0/changelog_recipient << EOF
-#   alice@example.com
-#   bob@example.com
-#   EOF
-#
-# The script tracks its last run using a git tag 'changelog-last-run'.
-# On first run (no tag), it defaults to the previous Friday at 4pm.

-You are summarizing changes for a weekly engineering update email.
-
-Read the following list of merged PRs and create a concise synopsis grouped by theme/feature/area of the codebase.
-
-Structure:
-1. <h1> title (e.g., "Eagle0 Weekly Update")
-2. <h2>BLUF</h2> (Bottom Line Up Front) - A short prose paragraph (2-4 sentences) highlighting the 1-3 most important changes this week and what to look for when testing. This should be conversational and help readers quickly understand what matters most.
-3. Synopsis sections (<h2> headings with bullet point summaries)
-4. <hr> divider
-5. <h2>PR Details</h2> with the same groupings, but smaller (<h3> headings) and listing PR links
-   - Format each PR as: <a href="${repo_url}/pull/NUMBER">#NUMBER</a>: Title
-
-Guidelines for the SYNOPSIS sections:
-- Group related changes together under clear headings (use <h2> tags)
-- Use bullet points (<ul><li>) for individual changes
-- Highlight any significant new features, breaking changes, or important fixes
-- Keep the tone professional but accessible
-- Don't include PR numbers in the synopsis - focus on what changed and why it matters
-
-IMPORTANT: Output valid HTML that can be used directly in an email body. Do NOT wrap in \`\`\`html code blocks - just output the raw HTML.
-
-Here are the merged PRs:

-# MCTS (Monte Carlo Tree Search) Framework
-
-This directory contains a game-agnostic Monte Carlo Tree Search implementation that can be used with any turn-based game. The framework separates the MCTS algorithm from game-specific logic through abstract interfaces.
-
-## Core Abstract Classes
-
-### `MCTSAction` (abstract/MCTSAction.hpp)
-Abstract interface for representing game actions/moves.
-
-**Key Methods:**
-- `getIndex()` - Returns the action's unique identifier
-- `getDescription()` - Human-readable description for debugging/logging
-- `clone()` - Creates a deep copy of the action
-- `equals()` - Compares actions for equality
-
-### `MCTSGameState` (abstract/MCTSGameState.hpp)
-Abstract interface for representing game states.
-
-**Key Methods:**
-- `hash()` - Returns a hash for transposition table lookups
-- `score(playerId)` - Evaluates the state's value for a given player
-- `currentPlayerId()` - Returns whose turn it is
-- `isTerminal()` - Checks if the game has ended
-- `getWinner()` - Returns the winning player (if terminal)
-- `clone()` - Creates a deep copy of the state
-- `equals()` - Compares states for equality
-
-### `MCTSGameEngine` (abstract/MCTSGameEngine.hpp)
-Abstract interface for game rule enforcement and state transitions. Many methods have efficient default implementations.
-
-**Must Override (Pure Virtual):**
-- `applyAction(state, action)` - Applies an action to create a new state
-- `getLegalActions(state)` - Returns all valid moves from a state
-- `isTerminal(state)` - Checks if a state is game-ending
-- `evaluateState(state, playerId)` - Scores a state for a player
-
-**Optional Overrides (Have Default Implementations):**
-- `applyActionMutable(state, action)` - Apply action in-place for efficiency (default: calls applyAction)
-- `filterActions(actions, state)` - Applies heuristic filtering (default: no filtering)
-- `simulateRandomPlayout(state, playerId, maxDepth, policy)` - Runs simulation (default: efficient mutable implementation)
-- `getActionScore(state, action, playerId)` - Scores an action (default: apply and evaluate)
-- `shouldStopSearch(state, iterations, startTime)` - Early termination (default: no early stop)
-
-**Performance Features:**
-- The default `simulateRandomPlayout` clones the state once and mutates it throughout simulation for efficiency
-- Games can override `applyActionMutable` to provide even more efficient in-place updates
-- Games can override `simulateRandomPlayout` for custom optimizations (e.g., using internal engine state)
-
-## MCTS Algorithm Implementation
-
-### `AbstractMCTSAI` (abstract/AbstractMCTSAI.hpp)
-The main MCTS algorithm implementation that works with any game implementing the abstract interfaces.
-
-**Key Features:**
-- **Selection**: Uses UCB1 (Upper Confidence Bound) for node selection
-- **Expansion**: Adds new nodes to the search tree
-- **Simulation**: Runs random playouts to estimate node values
-- **Backpropagation**: Updates node statistics with simulation results
-- **Multithreading**: Supports parallel MCTS with configurable thread count
-- **Path Compression**: Optimizes move sequences for better performance
-
-**Configuration Options:**
-- `explorationConstant` - UCB1 exploration parameter (default: √2)
-- `maxSimulationDepth` - Maximum depth for random playouts
-- `maxTreeDepth` - Maximum tree depth to prevent stack overflow
-- `useMultithreading` - Enable parallel search
-- `numThreads` - Number of worker threads
-- `simulationPolicy` - Strategy for action selection during simulation
-
-### `MCTSNode` (abstract/MCTSNode.hpp)
-Represents nodes in the MCTS search tree.
-
-**Core Data:**
-- `action` - The action that led to this node
-- `actionIndex` - Index in the original actions array
-- `gameState` - The game state at this node
-- `visitCount` - Number of times this node was visited
-- `totalReward` - Sum of simulation rewards
-- `averageReward` - Average reward (totalReward / visitCount)
-- `children` - Child nodes in the search tree
-- `parent` - Parent node reference
-
-**Key Methods:**
-- `CanExpand()` - Checks if node has untried actions
-- `GetBestChild(explorationConstant)` - UCB1-based child selection
-- `GetBestFinalChild()` - Most-visited child (for final move selection)
-- `CalculateUCB1(explorationConstant)` - Computes UCB1 value
-
-## Simulation Policies
-
-The framework supports multiple strategies for action selection during random playouts:
-
-- **RANDOM** - Uniform random selection
-- **FILTERED_RANDOM** - Random selection from filtered action set
-- **BEST_IMMEDIATE** - Always choose the highest-scoring immediate action
-- **WEIGHTED_BEST_IMMEDIATE** - Weighted random selection based on action scores
-
-## Type Definitions
-
-### `MCTSTypes` (abstract/MCTSTypes.hpp)
-- `MCTSPlayerId` - Player identifier type (int)
-- `MCTSSimulationPolicy` - Enumeration of simulation strategies
-- `MCTSConfig` - Configuration structure for MCTS parameters
-
-## Usage Pattern
-
-To use this framework with your game:
-
-1. **Implement the abstract interfaces** for your game:
-   ```cpp
-   class MyGameAction : public MCTSAction { /* ... */ };
-   class MyGameState : public MCTSGameState { /* ... */ };
-   class MyGameEngine : public MCTSGameEngine { /* ... */ };
-   ```
-
-2. **Create and configure the AI**:
-   ```cpp
-   MCTSConfig config;
-   config.explorationConstant = 1.414;
-   config.maxSimulationDepth = 100;
-   AbstractMCTSAI ai(playerId, config);
-   ```
-
-3. **Run the search**:
-   ```cpp
-   auto actions = engine.getLegalActions(currentState);
-   auto result = ai.Search(engine, currentState, actions, timeLimit);
-   auto bestAction = actions[result.bestActionIndex];
-   ```
-
-## Testing
-
-The framework includes comprehensive tests using a Tic-Tac-Toe implementation:
-- `MockTicTacToe.hpp` - Example implementation of all abstract interfaces
-- `AbstractMCTSAI_test.cpp` - Unit tests for the core algorithm
-- `MCTSIntegration_test.cpp` - Integration tests with complete games
-- `MCTSNode_test.cpp` - Tests for the node data structure
-
-This demonstrates how to implement the interfaces and validates that the MCTS algorithm works correctly with any turn-based game.

 - **Magnitude**: Indicates confidence/importance of the evaluation
 - **Relative scoring**: Only score differences matter, not absolute values
 
-This scoring system provides a robust framework for tactical AI decision-making, balancing immediate tactical gains with strategic objectives while handling the uncertainty inherent in combat outcomes.
-
-## AIScoreCalculator Function Reference
-
-### Public Interface Functions
-
-#### `GuessedStateScore`
-**Purpose**: Evaluates the score of a game state from the perspective of the current AI strategy without performing any commands.
-
-**Parameters**:
-- `isDefender`: Whether the AI is playing as defender
-- `state`: Current game state to evaluate
-- `aiStrategy`: Strategy being used (attack castles, hold castles, scatter, etc.)
-- `allCastleCoords`: Set of all castle coordinates on the map
-- `settingsGetter`: Game configuration and rules
-- `apdCache`: Cached action point distances for movement calculations
-- `alCache`: Cached attack locations for combat calculations
-
-**Returns**: Score value representing how favorable the state is for the evaluating player (positive = good, negative = bad)
-
-#### `CommandScore`
-**Purpose**: Evaluates the score for a specific command using lookahead search to consider future consequences.
-
-**Parameters**:
-- `pid`: Player ID executing the command
-- `isDefender`: Whether the player is a defender
-- `remainingLookahead`: Depth of recursive search remaining
-- `maxRepeatCount`: Number of random simulations for non-deterministic commands

-
-### Tree vs. Legacy Approach Comparison
-
-| Aspect | Legacy (Single Best) | Tree-Based (Complete) |
-|--------|---------------------|----------------------|
-| **Output** | Best command only | Complete decision tree |
-| **Memory** | Minimal | Higher (stores all paths) |
-| **Analysis** | Limited visibility | Full decision transparency |
-| **Debugging** | Single command info | Complete move sequences |
-| **Performance** | Slightly faster | Comparable (same calculations) |
-| **Compatibility** | Direct usage | Wrapper maintains compatibility |
-
-### Usage Patterns
-
-**For AI Decision Making**:
-```cpp
-auto treeFuture = BuildDecisionTree(pid, isDefender, depth, maxRepeat,
-                                   engine, strategy, utility, settings,
-                                   castles, apdCache, alCache, deadline);
-CommandDecisionTree tree = treeFuture.get();
-size_t bestCommand = tree.bestCommand->commandIndex;
-```
-
-**For Analysis and Debugging**:
-```cpp
-CommandDecisionTree tree = treeFuture.get();
-// Examine all possible moves
-for (const auto& rootNode : tree.rootNodes) {
-    std::cout << "Command " << rootNode->commandIndex
-              << " Score: " << rootNode->lookaheadScore << std::endl;
-    // Traverse children to see consequences
-    for (const auto& child : rootNode->children) {
-        // ... analyze child moves
-    }
-}
-```
-
-**Legacy Compatibility**:
-```cpp
-// Existing code continues to work unchanged
-auto indexScoreFuture = BestCommandIndex(pid, isDefender, ...);
-IndexAndScore result = indexScoreFuture.get();
-size_t bestCommand = result.index;
-```
-
-The tree-based approach provides complete decision transparency while maintaining full backward compatibility with existing AI code.
-
-## MCTS Alternative: Randomness Handling Recommendations
-
-The new MCTS-based AI system is available in `MCTSAI.hpp/.cpp` and provides an alternative to the iterative deepening approach. However, the current MCTS implementation uses simplified randomness handling compared to the sophisticated approach in the original system.
-
-### Current MCTS Limitations
-
-1. **Expansion Phase**: Uses average rolls (0.5) for all commands during tree expansion
-2. **Simulation Phase**: Uses random command selection with average rolls
-3. **Missing**: No explicit chance nodes for commands with `HasOdds()`
-4. **Missing**: No multi-sample evaluation for stochastic commands
-
-### Recommended Improvements: Chance Node Integration
-
-#### 1. **Explicit Chance Nodes** (Highest Priority)
-
-For commands with `HasOdds()`, create explicit chance nodes in the MCTS tree:
-
-```cpp
-// During MCTSExpansion
-if (descriptor->HasOdds()) {
-    // Create TWO child nodes: success and failure
-    auto successNode = CreateMCTSNode(commandIndex, SUCCESS_VARIANT);
-    auto failureNode = CreateMCTSNode(commandIndex, FAILURE_VARIANT);
-
-    // Execute with deterministic rolls (matching original system)
-    ExecuteWithRoll(successNode, 1.0 - successChance/2.0);  // High roll
-    ExecuteWithRoll(failureNode, (1.0 - successChance)/2.0); // Low roll
-
-    // Set probability weights for selection
-    successNode->probabilityWeight = successChance;
-    failureNode->probabilityWeight = 1.0 - successChance;
-}
-```
-
-#### 2. **Weighted Selection for Chance Nodes**
-
-Modify `MCTSSelection` to handle chance nodes:
-
-```cpp
-if (node->isChanceNode) {
-    // Select based on probability distribution, not UCB1
-    return SelectByProbability(node->children);
-} else {
-    // Normal UCB1 selection for decision nodes
-    return node->GetBestChild(explorationConstant);
-}
-```
-
-#### 3. **Probability-Weighted Backpropagation**
-
-Update backpropagation to account for chance node probabilities:
-
-```cpp
-void MCTSBackpropagation(MCTSNode* node, double reward) {
-    while (node) {
-        node->visitCount++;
-
-        // Weight reward by probability for chance nodes
-        double weightedReward = reward;
-        if (node->parent && node->parent->isChanceNode) {
-            weightedReward *= node->probabilityWeight;
-        }
-
-        node->totalReward += weightedReward;
-        node->averageReward = node->totalReward / node->visitCount;
-        node = node->parent;
-    }
-}
-```
-
-#### 4. **Multi-Sample Commands**
-
-For commands without explicit odds but with randomness, use stratified sampling:
-
-```cpp
-// During expansion, create multiple child nodes with different rolls
-for (int sample = 0; sample < numSamples; ++sample) {
-    double roll = static_cast<double>(sample) / (numSamples - 1);
-    auto sampleNode = CreateMCTSNodeWithRoll(commandIndex, roll);
-    sampleNode->probabilityWeight = 1.0 / numSamples;
-}
-```
-
-### Benefits of Chance Node Integration
-
-1. **Accurate Evaluation**: Preserves the sophisticated randomness handling from the original system
-2. **Better Convergence**: MCTS can properly explore both success/failure outcomes
-3. **Realistic Simulations**: Tree accurately represents game's probability distributions
-4. **Comparable Results**: Makes MCTS results directly comparable to iterative deepening
-
-### Implementation Priority
-
-1. **Phase 1**: Add explicit chance nodes for `HasOdds()` commands
-2. **Phase 2**: Implement probability-weighted selection and backpropagation
-3. **Phase 3**: Add multi-sample support for general stochastic commands
-4. **Phase 4**: Optimize performance with lazy expansion of chance nodes
-
-### Alternative: Determinization Approach
-
-If explicit chance nodes prove too complex, consider **determinization**:
-
-- Run multiple MCTS trees with different fixed random seeds
-- Aggregate results across all determinizations
-- Simpler to implement but potentially less accurate than explicit chance nodes
-
-### Switching Between AI Systems
-
-Both AI systems (`IterativeDeepeningAI` and `MCTSAI`) implement compatible interfaces. The algorithm is selected at **runtime** via the ShardokAIClient constructor:
-
-```cpp
-// Using Iterative Deepening (default)
-ShardokAIClient client(playerId, isDefender, hexMap, settings);
-// Or explicitly:
-ShardokAIClient client(playerId, isDefender, hexMap, settings,
-                      AIAlgorithmType::ITERATIVE_DEEPENING);
-
-// Using MCTS
-ShardokAIClient client(playerId, isDefender, hexMap, settings,
-                      AIAlgorithmType::MCTS);
-
-// Note: MCTS configuration can be customized via MCTSConfig:
-// - maxIterations: 10000 (max MCTS iterations per move)
-// - maxSimulationDepth: 10 (depth for rollout phase)
-// - maxTreeDepth: 20 (max tree depth to prevent stack overflow)
-// - explorationConstant: 1.414 (UCB1 exploration vs exploitation)
-// - useMultithreading: true (APD cache is thread-safe with TLS + mutex protection)
-// - numThreads: 4
-```
-
-The selection is made per AI client instance, allowing different algorithms for different players or game situations within the same server process.
-
-#### Direct AI Usage (Lower Level)
-
-Both AI systems can also be used directly:
-
-```cpp
-// Using Iterative Deepening directly
-auto iterativeAI = IterativeDeepeningAI(playerId, isDefender, strategy,
-                                       castleCoords, apdCache, alCache);
-auto result = iterativeAI.IterativeSearch(settings, state, commands, budget);
-
-// Using MCTS directly
-auto mctsAI = MCTSAI(playerId, isDefender, strategy,
-                    castleCoords, apdCache, alCache);
-auto result = mctsAI.Search(settings, state, commands, budget);
-```
-
-#### Algorithm Comparison
-
-| Feature | Iterative Deepening | MCTS |
-|---------|-------------------|------|
-| **Randomness Handling** | Sophisticated (chance nodes, multi-sample) | Simplified (average rolls) |
-| **Performance** | Single-threaded | Multithreaded |
-| **Search Type** | Fixed depth with iterative deepening | Adaptive with time budget |
-| **Memory Usage** | Lower | Higher (maintains tree) |
-| **Max Tree Depth** | Limited by lookahead setting | Limited by `maxTreeDepth` config (default: 20) |
-| **Tree Destruction** | Not applicable | Iterative (avoids stack overflow) |
-| **Best For** | Precise evaluation, production | Performance testing, fast decisions |
-
-The MCTS implementation provides a solid foundation. Known limitations:
-1. **Randomness Handling**: Simplified compared to iterative deepening (no explicit chance nodes)
-2. **Simulation Quality**: Uses random rollouts instead of sophisticated evaluation
-
-Note: The APD cache is fully thread-safe using thread-local storage and mutex-protected shared cache.
-
-Adding chance node handling and ensuring thread safety would make it a superior replacement for the iterative deepening approach while maintaining the sophisticated randomness evaluation that makes the current system effective.
-
-## MCTS Configuration Options
-
-The MCTS AI system provides extensive configuration through the `MCTSConfig` structure:
-
-### Core MCTS Parameters
-
-```cpp
-struct MCTSConfig {
-    double explorationConstant = 1.414;  // UCB1 constant (sqrt(2) by default)
-    int maxSimulationDepth = 1000;       // Maximum depth for rollout
-    int maxTreeDepth = 2000;             // Maximum tree depth to prevent stack overflow
-    bool useMultithreading = true;       // Enable parallel MCTS
-    int numThreads = 16;                 // Number of threads for parallel MCTS (when enabled)
-    MCTSSimulationPolicy simulationPolicy = MCTSSimulationPolicy::BEST_IMMEDIATE;
-    bool enableTranspositionDetection = true;  // Enable pruning of duplicate states
-    double immediateScoreTieBreakThreshold = 5.0;  // When avg rewards differ by less than this, prefer higher immediate score
-    double visitCountTolerance = 0.05;  // Treat visit counts as equal if within this % of best count
-    bool enableImmediateScoreInUCB1 = true;  // Apply immediate score tie-breaking in UCB1 selection too
-};
-```
-
-### Exploration vs Exploitation
-
-- **`explorationConstant`**: Controls the exploration vs exploitation balance in UCB1 selection
-  - Higher values (>1.414): More exploration of unvisited nodes
-  - Lower values (<1.414): More exploitation of known good moves
-  - Default: 1.414 (√2, theoretical optimum for UCB1)
-
-### Tree Structure Limits
-
-- **`maxTreeDepth`**: Prevents stack overflow in deep game trees
-  - Default: 2000 (very high limit for most tactical scenarios)
-  - Terminal detection stops expansion when this depth is reached
-
-- **`maxSimulationDepth`**: Controls rollout length during simulation phase
-  - Default: 1000 (sufficient for most tactical scenarios)
-  - Longer simulations provide more accurate estimates but use more time
-
-### Multithreading Configuration
-
-- **`useMultithreading`**: Enable/disable parallel MCTS execution
-  - Default: true (takes advantage of modern multi-core CPUs)
-  - Requires thread-safe game engine and scoring components
-
-- **`numThreads`**: Number of worker threads for parallel tree building
-  - Default: 16 (adjust based on available CPU cores)
-  - More threads can improve search speed but with diminishing returns
-
-### Simulation Policies
-
-The `MCTSSimulationPolicy` enum controls how commands are selected during the rollout phase:
-
-- **`RANDOM`**: Pure random selection from all available commands
-  - Fastest but least informed simulations
-  - Good baseline for testing MCTS convergence
-
-- **`FILTERED_RANDOM`**: Random selection from AICommandFilter-approved commands
-  - Eliminates obviously bad moves (moving away from objectives, etc.)
-  - Better simulation quality with minimal overhead
-
-- **`BEST_IMMEDIATE`**: Always choose command with highest immediate score
-  - Most informed simulations
-  - Slower but higher quality rollouts
-  - Default setting for production use
-
-- **`WEIGHTED_BEST_IMMEDIATE`**: Random selection weighted by immediate score ranking
-  - Balances exploration with informed choice
-  - Alternative to pure greedy selection
-
-### Transposition Detection
-
-- **`enableTranspositionDetection`**: Enable pruning of duplicate game states
-  - Default: true (improves search efficiency)
-  - Uses hash-based state identification
-  - Prevents wasted computation on equivalent positions reached via different move sequences
-
-### Immediate Score Tie-Breaking
-
-These settings address MCTS's tendency to choose indirect paths when direct paths lead to the same outcome:
-
-- **`immediateScoreTieBreakThreshold`**: Score difference threshold for tie-breaking
-  - Default: 5.0 (when backpropagated rewards differ by less than this, prefer immediate score)
-  - Helps AI choose direct moves over equivalent indirect sequences
-  - Improves user experience by reducing unnecessary intermediate moves
-
-- **`visitCountTolerance`**: Visit count equality threshold for tie-breaking
-  - Default: 0.05 (5% tolerance - visit counts within this percentage are considered equal)
-  - Prevents minor visit count differences from overriding immediate score preferences
-
-- **`enableImmediateScoreInUCB1`**: Apply immediate score tie-breaking during exploration
-  - Default: true (consistent tie-breaking in both exploration and final selection)
-  - When UCB1 values are very close, prefer nodes with higher immediate scores
-  - Improves convergence on direct paths to objectives
-
-### Usage Example
-
-```cpp
-// Custom MCTS configuration for performance testing
-MCTSConfig config;
-config.explorationConstant = 2.0;  // More exploration
-config.simulationPolicy = MCTSSimulationPolicy::FILTERED_RANDOM;  // Faster rollouts
-config.numThreads = 8;  // Reduce threads for testing environment
-config.immediateScoreTieBreakThreshold = 10.0;  // More aggressive tie-breaking
-
-MCTSAI ai(playerId, isDefender, strategy, castleCoords, apdCache, alCache, config);
-```
-
-### Configuration Recommendations
-
-**For Production Use:**
-- Use default settings for balanced performance and quality
-- Consider reducing `numThreads` on systems with limited CPU cores
-- `BEST_IMMEDIATE` simulation policy provides highest quality decisions
-
-**For Performance Testing:**
-- `FILTERED_RANDOM` or `RANDOM` simulation policies for faster rollouts
-- Lower `explorationConstant` (1.0) for more exploitation
-- Disable transposition detection for baseline comparison
-
-**For Analysis/Debugging:**
-- Single-threaded execution (`useMultithreading = false`) for deterministic results
-- Higher `immediateScoreTieBreakThreshold` to emphasize direct paths
-- `BEST_IMMEDIATE` simulation for most predictable behavior
-
-The configuration system allows fine-tuning MCTS behavior for different scenarios while maintaining compatibility with the existing AI infrastructure.
+This scoring system provides a robust framework for tactical AI decision-making, balancing immediate tactical gains with strategic objectives while handling the uncertainty inherent in combat outcomes.
