+## CRITICAL GIT RULES (NEVER VIOLATE)
+
+**NEVER push directly to main/master.** No exceptions. Not for "small changes." Not for docs. Not ever.
+
+**NEVER merge PRs.** You create PRs. The user merges them. No exceptions.
+
+**ALWAYS use this workflow:**
+1. Create a feature branch from origin/main
+2. Commit to that branch
+3. Create a PR with `gh pr create`
+4. Wait for user to merge (DO NOT run `gh pr merge`)
+
+If you catch yourself about to run `git push origin main` or `git push origin <branch>:main`, STOP. You are about to violate a critical rule. Create a PR instead.
+
+If you catch yourself about to run `gh pr merge`, STOP. Only the user merges PRs.

+
+**MANDATORY: Before running `git commit`, verify:**
+
+1. **If you modified any BUILD.bazel file:** Run `bazel run gazelle` and stage any changes it makes

+### 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

+## 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

+# 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] `AttackCommandChooser` - uses Scala `GameState` and `BattalionViewC` (Scala view type)
+- [x] `BattalionPower` - has `estimatedPower(BattalionViewC)` for recon data with optional stats
+- [x] `CommandChoiceHelpers` - fully protoless, uses Scala `GameState` throughout
+- [x] `ProvinceGoldSurplusCalculator` - fully protoless (callers use converters)
+- [x] `HeroSelector` - fully protoless (removed dead `minimallyFatiguedHeroesProto`)
+
+### AI Layer ✅ COMPLETE
+
+All AI and command chooser code is now fully protoless:
+- [x] `AttackDecisionCommandChooser` - uses Scala GameState
+- [x] `CommandChooser` - trait uses Scala GameState
+- [x] `FulfillQuestsCommandSelector` - uses Scala GameState
+- [x] `MidGameAIClient` - uses Scala GameState internally
+
+### Still Using Proto GameState (Boundary Code)
+
+These files use proto GameState because they're at system boundaries:
+
+**View Filters (client projection):**
+- `view_filters/GameStateViewFilter` - has Scala overload, uses Scala sub-filters
+- `view_filters/ProvinceViewFilter` - has Scala overloads for some methods
+- `view_filters/FactionViewFilter` - has Scala overload
+- `view_filters/HeroViewFilter` - has Scala overload
+- `view_filters/BattalionNameFilter` - has Scala overload
+- `view_filters/BattleFilter` - has Scala overload
+
+**Legacy Utilities (to be deprecated):**
+- `LegacyProvinceDistances`, `LegacyFactionUtils`, `LegacyHeroUtils`, etc.
+- Used by code that still needs proto GameState
+
+**Persistence/Action System:**
+- `ActionResultTApplier`, `ActionResultProtoApplier` - apply results to proto state
+- `ActionWithResultingState` - caches both proto and Scala state
+
+**Shardok Interface (gRPC boundary):**
+- `ShardokInterfaceGrpcClient`, `ShardokInterfaceProxy` - must use proto for C++ communication
+
+## Next Steps
+
+### Phase 1-3: AI Layer ✅ COMPLETE
+
+The entire AI decision-making layer is now protoless.
+
+### Phase 4: View Filters ✅ COMPLETE
+
+The view_filters package migration is complete:
+
+**Completed:**
+- [x] `GameStateViewFilter` - added Scala GameState overload (uses Scala sub-filters)
+- [x] `ProvinceViewFilter` - already has Scala overloads for server-side views
+- [x] `HumanPlayerClientConnectionState` - updated to pass Scala GameState directly
+- [x] `HeroViewFilter` - added Scala overload
+- [x] `FactionViewFilter` - added Scala overload
+- [x] `Visibility` - added Scala overloads
+
+**Still Using Proto:**
+- [x] `BattalionNameFilter` - has Scala overload
+- [x] `BattleFilter` - has Scala overload
+- [ ] `ActionResultFilter` - uses proto internally (boundary code)
+
+**Strategy:**
+1. Add Scala GameState overloads to view filter methods
+2. Update callers to pass Scala GameState where available
+3. Eventually deprecate proto versions
+
+### Phase 5: Legacy Utility Cleanup (IN PROGRESS)
+
+Remove Legacy* utilities by migrating remaining callers:
+1. Identify callers of each Legacy* util
+2. Update callers to use protoless versions
+3. Delete Legacy* files when no longer needed
+
+**Deleted (no production callers):**
+- [x] `LegacyProvinceDistances` - deleted (no callers)
+- [x] `LegacyBattalionSuitability` - deleted (no callers)
+- [x] `LegacyFoodConsumptionUtils` - deleted (no callers)
+- [x] `LegacyHandleRiotUtils` - deleted (no callers)
+
+**Refactored to Thin Wrappers (delegating to protoless versions):**
+- [x] `LegacyRansomValidity` - already a thin wrapper delegating to `RansomValidity`
+- [x] `LegacyRecruitmentOdds` - refactored to delegate to `RecruitmentOdds`
+
+**Parallel Implementations (proto mirrors protoless):**
+- [x] `FactionUtils` / `LegacyFactionUtils` - both have matching APIs; LegacyFactionUtils used by boundary code (24+ callers)
+- [x] `HeroUtils` / `LegacyHeroUtils` - both have matching APIs; LegacyHeroUtils used by boundary code (10 callers)
+- [x] `ProvinceUtils` / `LegacyProvinceUtils` - both have matching APIs; LegacyProvinceUtils used by boundary code (20 callers: availability factories, view filters)
+
+**Parallel Implementations (awaiting migration of callers):**
+- [x] `BattalionUtils` / `LegacyBattalionUtils` - both have matching core methods; LegacyBattalionUtils used by boundary code (4 callers)
+- [x] `BattalionViewFilter` / `LegacyBattalionViewFilter` - protoless version exists; Legacy used by view filters, action appliers (3 callers)
+- [x] `BattalionTypeFinder` / `LegacyBattalionTypeFinder` - protoless version exists; Legacy used by validators (1 caller: RuntimeValidator)
+
+### Recent Caller Migration
+
+**CheckForFulfilledQuestsAction** - migrated to use protoless `BattalionTypeFinder`:
+- Changed `battalionTypes` parameter from proto `Vector[BattalionType]` to Scala `Vector[BattalionType]`
+- Updated callers (EngineImpl, EndVassalCommandsPhaseAction) to pass Scala types directly
+- Eliminated wasteful `BattalionTypeConverter.toProto()` conversions
+
+**ExpandedUnaffiliatedHeroUtils** - added Scala overload:
+- New overload takes Scala `GameState` and `UnaffiliatedHeroT` directly
+- Added `UnaffiliatedHeroConverter.unaffiliatedHeroTypeToProto()` helper for efficient enum conversion
+- Proto overload retained for backward compatibility
+
+**AvailablePleaseRecruitMeCommandFactory** - eliminated wasteful proto conversions:
+- Now uses `ExpandedUnaffiliatedHeroUtils.expandedUnaffiliatedHero(ScalaGameState, UnaffiliatedHeroT)` directly
+- Removed `GameStateConverter.toProto()` and `UnaffiliatedHeroConverter.toProto()` calls
+- Factory is now fully protoless internally (still returns proto types for API boundary)
+
+**ProvinceViewFilter** - added Scala overload with faction filtering:
+- New `filteredProvinceView(province: ProvinceT, gs: ScalaGameState, factionId: FactionId)` overload
+- Uses protoless `FactionUtils.hasAlliance`, `Visibility.hasFullVisibility`, and `ProvinceUtils.incomingOthers`
+- Handles reconned provinces directly from Scala `FactionT.reconnedProvinces` (already Scala type)
+- Added helper methods: `fullProvinceInfoScala`, `maybeIncomingAttackersScala`, `unaffiliatedHeroInfoScala`
+- Events still converted to proto at the end (ProvinceView.knownEvents uses proto events)
+
+**GameStateViewFilter** - eliminated GameStateConverter.toProto() call:
+- Scala overload now fully protoless internally
+- Uses the new ProvinceViewFilter Scala overload with faction filtering
+- Converts `battalionTypes` and `chronicleEntries` to proto only at output boundary
+
+## 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/`) is now fully protoless
+- Proto GameState is still needed at boundaries: persistence, gRPC to Shardok
+- `PerformUnaffiliatedHeroesAction` and the LLM pipeline use protoless `GameState`
+- `GameStateViewFilter` Scala overload is now fully protoless internally (converts to proto only at output)
+- `ProvinceViewFilter` has Scala overloads for all three modes: no filtering, faction filtering, and withdrawn-from view

+
+### Cleanup Candidates (Priority Order)
+
+1. **Delete proto overloads where Scala overloads exist and proto unused**
+   - `IncomingArmyUtils.scala` - verify all main callers use Scala overloads
+   - `ArmyUtils.scala` - verify all main callers use Scala overloads
+
+2. **Move test-only utilities to test code**
+   - `IDable.scala` - only used by tests (except StartGameActionResultUtils)
+
+3. **Create Scala versions of common enums**
+   - `DiplomacyOfferStatus` → already done in availability package
+   - `ImprovementType` → used by ImproveCommandSelector, CommandChoiceHelpers
+   - `BattalionTypeId` → used by multiple command selectors
+
+4. **Large refactoring (requires Scala AvailableCommand/SelectedCommand)**
+   - `command_choice_helpers/` package (57 imports) - uses proto API command types
+   - Would need Scala versions of AvailableCommand and SelectedCommand hierarchies

+# 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
+
+### Directory Structure

+└─────────────────────────────────────────────────────────────┘
+```
+
+### 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 |
+
+### Settings UI
+
+```
+┌─────────────────────────────────────────────────────────────┐
+│  Eagle Admin                          [Games] [Health]       │
+├─────────────────────────────────────────────────────────────┤
+│                                                             │

+│  │ ActionVigorCost (Int)                                │   │

+│  └─────────────────────────────────────────────────────┘   │
+│                                                             │
+│  ┌─────────────────────────────────────────────────────┐   │
+│  │ BaseFoodBuyPrice (Double)                            │   │
+│  │ Current: [0.5   ] Default: 0.5             [Save]    │   │
+│  └─────────────────────────────────────────────────────┘   │
+│                                                             │
+│  ... (275 settings, virtualized/paginated) ...              │
+│                                                             │
+└─────────────────────────────────────────────────────────────┘
+```
+
+### 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.
+
+---
+
+## Implementation Phases
+
+### Phase 1: Web UI Foundation
+
+**Status: Complete**
+
+1. ✅ Set up Go templates with `embed`
+2. ✅ Add Pico CSS and htmx
+3. ✅ Create base layout with navigation
+4. ✅ Convert `/games` to HTML with styling
+5. ✅ Add game detail page with history table
+6. ✅ Implement htmx infinite scroll for history
+7. ✅ Reverse history order (most recent first)
+8. ✅ Clickable action rows that expand to show JSON representation
+9. ✅ Add `/games/{id}/action/{index}` endpoint for fetching action details
+
+**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)
+2. ✅ Add `getAllSettings` method to auto-generated `SettingsLoader`
+3. ✅ Implement `getSettings` in `EagleServiceImpl`
+4. ✅ Create settings list page with live search
+5. ✅ Add inline editing with htmx
+6. ✅ Modified settings are highlighted
+
+**Deliverable**: View and edit settings via admin UI
+
+### Phase 3: Game Rewind
+
+**Status: Complete**
+
+1. ✅ Add `RewindGame` to `eagle.proto`
+2. ✅ Implement `stateAt` and `truncateTo` in `GameHistory`
+3. ✅ Implement rewind logic in `Engine` and `GameController`
+4. ✅ Add rewind confirmation (htmx `hx-confirm` dialog)
+5. ✅ Handle client disconnection gracefully
+6. ✅ Add rewind button to history rows
+7. ✅ Implement `rewindGame` in `GamesManager` and `EagleServiceImpl`
+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?

+## Action Items
+
+### Must Verify Before Opening Public Access:
+
+1. ~~**Stock images** - The JPG files with stock image filenames need review.~~ **DONE** - Deleted lee-ermy, kisspng, stock-illustration, Yosemite Sam, and images.jpeg (2025-01-04)
+
+2. **Clip art images** - Unknown license, need replacement with properly licensed alternatives:
+   - `Assets/Shardok/commandImages/bridge.png` - wooden bridge icon
+   - `Assets/Images/startFire.png` - fire icon
+
+3. **Shardok sound effects** - 56 MP3 files of unknown origin. Either:
+   - Document their source
+   - Replace with known-licensed alternatives
+   - Confirm they were custom-created
+
+4. **Terrain Hexes** - 85 hex tiles of unknown source
+   - **TODO:** Confirm if this is a Unity Asset Store purchase (owner believes it is)
+
+5. **StrategyGameIcons** - 138 icons of unknown source
+   - **TODO:** Investigate origin - check Unity Asset Store purchase history
+
+6. **AUDIUS music tracks** - Verify Dima Koltsov tracks are licensed for commercial use
+
+7. **Discord logo** (`Eagle/Discord-Logo-Blurple.png`) - Likely fine for "Login with Discord" button per Discord brand guidelines, but verify usage complies with their terms

+- CC-licensed music (attribution in Music Credits.txt)
+- CC0 SimpleFileBrowser icons
+- Google Fonts / Liberation fonts
+- NuGet packages
+
+---
+
+## Recommendation
+
+Before removing HTTP basic auth:
+
+1. ~~Delete or replace the 4 suspicious JPG/JPEG files in `Assets/Eagle/` and `Assets/Images/`~~ **DONE** (2025-01-04)
+2. Replace clip art images (`bridge.png`, `startFire.png`) with properly licensed alternatives (e.g., from [game-icons.net](https://game-icons.net) CC BY 3.0)
+3. Verify source of `Assets/Shardok/soundEffects/` MP3s
+4. Verify source of `Assets/Terrain Hexes/` and `Assets/StrategyGameIcons/`
+5. If any are from early development with unclear licensing, replace them
+
+The bulk of your assets (95%+) are properly licensed Asset Store purchases or CC content.

+## 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` | ✅ Fully protoless | Complete (PR #5048) |
+| `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: 52 of 52 action files (100%) are fully protoless.** ✅
+
+All action files have been migrated to use Scala types:
+
+| Action | Status | Notes |
+|--------|--------|-------|
+| `ResolveBattleAction` | ✅ Complete | PR #5048 - uses Scala GameState and ActionResultApplier |
+| `PerformVassalCommandsPhaseAction` | ✅ Complete | Uses Scala types via CommandChoiceHelpers |
+| `EndHandleRiotsPhaseAction` | ✅ Complete | Uses Scala types via CommandChoiceHelpers |
+| `PerformVassalDefenseDecisionsAction` | ✅ Complete | Uses Scala types via CommandChoiceHelpers |
+| `EndVassalCommandsPhaseAction` | ✅ Complete | Uses Scala types via CommandChoiceHelpers |
+
+**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 |
+|-----------|-------|------------|--------|
+| History API updates | ~100 | Low | - |
+| **Total Remaining** | **~100** | | |
+
+**Completed:**
+- ✅ `ChronicleEventGenerator` converted to return Scala `ChronicleEvent` types directly
+- ✅ `CommandChoiceHelpers` migrated to Scala types
+- ✅ `ResolveBattleAction` refactored to use Scala GameState and ActionResultApplier (PR #5048)
+
+### Enum Type Migrations
+
+Proto enums are being converted to Scala sealed traits with converters at boundaries:
+
+| Enum | Scala Type | Status | Notes |
+|------|------------|--------|-------|
+| `DiplomacyOfferStatus` | `Status` sealed trait | ✅ **Complete** | PR #5093 - `EligibleDiplomacyStatuses` uses Scala types internally |
+| `RoundPhase` | `RoundPhase` sealed trait | Partial | Some usages converted |
+| `BattalionType` | `BattalionType` sealed trait | Partial | Some usages converted |
+
+**DiplomacyOfferStatus Migration (PR #5093):**
+- `EligibleDiplomacyStatuses.scala` now returns `Vector[Status]` instead of `Vector[DiplomacyOfferStatus]`
+- Call sites in `AvailableResolve*CommandFactory` files convert to proto via `StatusConverter.toProto` at the boundary
+- This pattern should be applied to other proto enums
+
+### 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` | ✅ **Protoless** | Uses Scala `GameState` throughout |
+| `ProvinceGoldSurplusCalculator.scala` | ✅ **Protoless** | Uses Scala types |
+
+**All CommandChoiceHelpers selectors have been migrated to Scala types.** ✅
+
+### Progress Summary
+
+| Metric | Value |
+|--------|-------|
+| Action files fully protoless | 52 / 52 (100%) ✅ |
+| Proto usages in remaining actions | 0 |
+| Next target | See "Next Candidates" section below |
+
+### Next Candidates
+
+Priority candidates for further deproto work:
+
+1. **More Enum Migrations** - Apply the `DiplomacyOfferStatus` pattern to other proto enums:
+   - Files importing `net.eagle0.eagle.common.round_phase.RoundPhase` (proto) could use Scala `RoundPhase`
+   - Files importing `net.eagle0.eagle.common.battalion_type.BattalionType` (proto) could use Scala `BattalionType`
+
+2. **AvailableCommandsFactory Files** - Many still use proto `GameState` internally:
+   - These files build proto `AvailableCommand` messages but could use Scala types for internal logic
+   - Convert to accept Scala `GameState`, only convert fields to proto when building the response
+
+3. **History APIs** - `InMemoryHistory` and `PersistedHistory`:
+   - Change to vend Scala `GameState` and `ActionResultT` instead of proto versions
+   - `PersistedHistory` converts to proto internally for disk persistence
+
+### 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
+- [x] `CommandChoiceHelpers` uses Scala types ✅
+- [x] All action files (52/52) are fully protoless ✅
+- [ ] `ProvinceViewFilter` faction-filtered views use 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

+Generate a 256-bit random token for Eagle-Shardok authentication:
+
+```bash
+openssl rand -hex 32
+```
+
+Save this output - it's the shared secret between Eagle and Shardok.
+
+---
+
+## Step 4: Store Secrets in GitHub Actions
+
+Add these secrets in GitHub → Settings → Secrets and variables → Actions:
+
+| Secret Name | Description |
+|-------------|-------------|
+| `HETZNER_API_TOKEN` | From Step 2 - for Hetzner API calls |
+| `SHARDOK_AUTH_TOKEN` | From Step 3 - shared secret for gRPC auth |
+
+Note: `DO_REGISTRY_TOKEN` already exists and will be used for Hetzner to pull container images.
+
+These secrets will be passed to Eagle at runtime via `docker_build.yml`, similar to how `OPENAI_API_KEY` and other secrets are handled.
+
+---
+
+## Step 5: DNS Setup (for Let's Encrypt)
+
+You need a domain pointing to the Shardok instance for TLS certificates.
+
+### Option A: Floating IP (Recommended)
+
+1. In Hetzner Console → Networking → Floating IPs
+2. Create a **Floating IPv6** in **Hillsboro, Oregon (hil)** region
+   - IPv6 costs €1/month vs €3/month for IPv4
+   - Hillsboro has better latency to DigitalOcean SFO than Ashburn
+   - Server-to-server communication works fine with IPv6-only
+3. Point `shardok.prod.eagle0.net` to this IP via AAAA record
+4. The ShardokInstanceManager will attach this IP to instances on spin-up
+
+**Location choice**: Hillsboro, OR (`hil`) is recommended for US West Coast. Same pricing as Ashburn (`ash`).
+
+### Option B: Dynamic DNS
+
+Update DNS programmatically when instance spins up. More complex but avoids floating IP cost.
+
+---
+
+## Step 6: Upload SSH Key to Hetzner
+
+For debugging access to instances:
+
+1. In Hetzner Console → Security → SSH Keys
+2. Click "Add SSH Key"
+3. Paste your public key (e.g., `~/.ssh/id_rsa.pub`)
+4. Give it a name (e.g., "eagle-deploy")
+
+---
+
+## Step 7: Wire Security Config into Eagle
+
+Update Eagle's startup code to use the security config when connecting to remote Shardok:
+
+```scala
+val securityConfig = ShardokSecurityConfig(
+  useTls = true,
+  authToken = Some(sys.env("SHARDOK_AUTH_TOKEN"))
+)
+
+val channel = ServerSetupHelpers.newChannel(
+  "shardok.prod.eagle0.net",
+  50051,
+  securityConfig
+)
+```
+
+---
+
+## Testing
+
+### Manual Instance Spin-up
+
+Test the Hetzner integration by triggering instance creation:
+
+```scala
+val manager = new ShardokInstanceManager(
+  hetznerApiToken = sys.env("HETZNER_API_TOKEN"),
+  // ... other config
+)
+
+manager.ensureInstanceRunning()
+```
+
+### Verify TLS and Auth
+
+1. Instance spins up and gets Let's Encrypt certificate
+2. Eagle connects via TLS
+3. Auth token is validated on each request
+
+---
+
+## Cost Estimate
+
+| Component | Cost |
+|-----------|------|
+| CAX41 (16 ARM cores) | ~$0.04/hour |
+| Floating IP | ~$4/month |
+| Typical usage (20 hrs/week) | ~$3.50/month compute |
+
+**Total: ~$7-8/month** for typical usage.
+
+---
+
+## Troubleshooting
+
+### Instance won't start
+- Check Hetzner API token has Read & Write permissions
+- Verify you're using the correct region (`hil` for Hillsboro OR, or `ash` for Ashburn VA)
+
+### TLS certificate fails
+- Ensure DNS points to the instance IP before certbot runs
+- Check port 80 is open for Let's Encrypt HTTP-01 challenge
+
+### Auth failures
+- Verify `SHARDOK_AUTH_TOKEN` matches on both Eagle and Shardok
+- Check the token file is readable by Shardok container
+
+### Can't pull container image
+- Ensure `DO_REGISTRY_TOKEN` is passed to cloud-init
+- Verify the ARM64 image exists: `registry.digitalocean.com/eagle0/shardok-server:arm64-latest`

+# Plan: Extract OAuth to Go Service
+
+## Goal
+Move OAuth authentication handling from the Eagle Scala server into a separate Go service. This simplifies Eagle (gRPC-only, no HTTP), reduces complexity, and sets up for potentially moving JWT validation outside Eagle too.
+
+## Architecture Decision: Sidecar Service (Not DO Functions)
+
+**Recommendation: Go sidecar service on the same droplet, in a separate container**
+
+**Why not DO Functions:**
+- OAuth requires **stateful sessions** (pendingOAuth/completedOAuth maps with 10-min TTL)
+- Client polling pattern (every 2 seconds) would incur high function invocation costs
+- Cold start latency problematic for auth flows
+- State would require external store (Redis), adding complexity
+
+**Why sidecar (separate container):**
+- Simple process on same droplet, minimal network latency
+- In-memory state management (like current Scala impl)
+- Easy to monitor/debug alongside Eagle
+- Can share filesystem for key files (RSA keys) via volume mounts
+- **Independent deployment**: Deploying Eagle doesn't restart auth service (and vice versa)
+- **Independent scaling**: Could move to separate droplet later if needed
+
+## Current Architecture (What Exists)
+
+```
+Unity Client
+    ├── GetOAuthUrl RPC → Eagle AuthServiceImpl → OAuthService.getAuthUrl()
+    ├── [User browser auth] → HTTP callback → OAuthHttpHandler → OAuthService.handleCallback()
+    ├── CheckOAuthStatus RPC (polling) → AuthServiceImpl → OAuthService.checkStatus()
+    └── All other RPCs include JWT → AuthorizationInterceptor validates
+```
+
+**Key files:**
+- `src/main/scala/net/eagle0/eagle/auth/OAuthService.scala` - OAuth flow, state management
+- `src/main/scala/net/eagle0/eagle/auth/JwtService.scala` - JWT creation/validation
+- `src/main/scala/net/eagle0/eagle/auth/UserService.scala` - User CRUD (persisted)

+
+## Component Responsibilities
+
+### Go Auth Service (NEW - separate container)
+- **OAuth flow**: getAuthUrl, handleCallback (HTTP), checkStatus
+- **State management**: pendingOAuth, completedOAuth maps with TTL
+- **JWT creation**: Issue access/refresh tokens (shares RSA private key with Eagle)
+- **Token refresh**: Validate refresh token, issue new access token
+- Calls Eagle's internal UserService gRPC to find/create users
+
+### Eagle Server (SIMPLIFIED)
+- **JWT validation**: AuthorizationInterceptor stays (validates tokens on game RPCs)
+- **UserService**: Stays in Eagle (user persistence, display name logic)
+- **New internal gRPC**: Expose GetOrCreateUser, GetUser for Go service to call
+- **Proxy (Phase 1)**: Forward OAuth RPCs to Go service
+- **Remove (Phase 2)**: OAuthService, OAuthHttpHandler, HTTP server setup
+
+### Unity Client (NO CHANGES in Phase 1)
+- Eagle proxies Auth RPCs to Go service
+- Client still connects to Eagle on port 40032
+
+## Implementation Phases
+
+### Phase 1: Go Auth Service with Eagle Proxy (Zero Client Changes)
+
+1. **Create Go service structure**
+   ```
+   src/main/go/net/eagle0/authservice/
+   ├── main.go           # Entry point, starts gRPC + HTTP servers
+   ├── oauth.go          # OAuth state management, provider configs
+   ├── jwt.go            # JWT creation (copy logic from Scala)
+   ├── handlers.go       # gRPC handlers for Auth service
+   ├── http_callback.go  # HTTP handler for OAuth callback
+   └── BUILD.bazel
+   ```
+
+2. **Internal gRPC proto for Eagle UserService**
+   ```protobuf
+   // src/main/protobuf/net/eagle0/eagle/internal/auth_internal.proto
+
+   service InternalUserService {
+     rpc GetOrCreateUser(GetOrCreateUserRequest) returns (GetOrCreateUserResponse);
+     rpc GetUser(GetUserRequest) returns (GetUserResponse);
+   }
+
+   message GetOrCreateUserRequest {
+     string provider = 1;        // "discord" or "google"
+     string provider_user_id = 2;
+     string email = 3;
+     string avatar_url = 4;
+   }
+
+   message GetOrCreateUserResponse {
+     string user_id = 1;
+     string display_name = 2;
+     string avatar_url = 3;
+     bool is_admin = 4;
+     bool is_new_user = 5;
+   }
+   ```
+
+3. **Eagle: Expose InternalUserService**
+   - New `InternalUserServiceImpl.scala` wrapping UserService
+   - Bind to same port, different service name (internal only)
+
+4. **Eagle: Proxy Auth RPCs to Go**
+   - AuthServiceImpl delegates GetOAuthUrl, CheckOAuthStatus, RefreshToken to Go service
+   - SetDisplayName, GetCurrentUser, Logout stay in Eagle
+
+5. **Share RSA keys via volume mount**
+   - Go service reads same key files as Eagle
+   - Both can create valid JWTs
+   - Eagle continues to validate JWTs
+
+6. **Docker/Container setup**
+   - New Dockerfile for Go auth service
+   - docker-compose or Kubernetes config for both containers
+   - Shared volume for /etc/eagle0/keys/
+   - Internal network for container-to-container gRPC
+
+### Phase 2: Client Direct to Go Service (Future)
+
+1. **Update Unity client**
+   - Connect to Go Auth service directly for OAuth RPCs
+   - Keep connecting to Eagle for game RPCs
+
+2. **Remove Eagle proxy code**
+   - Delete AuthServiceImpl OAuth delegation
+   - AuthServiceImpl only handles SetDisplayName, GetCurrentUser, Logout
+
+### Phase 3: Move JWT Validation to Go (Optional Future)
+
+1. **Go service validates JWTs**
+   - Add ValidateToken RPC or use shared middleware pattern
+
+2. **Eagle calls Go for validation**
+   - AuthorizationInterceptor calls Go to validate tokens
+   - OR: Use stateless validation (both share public key)
+

+
+### Docker/Deployment
+- `ci/auth_service.Dockerfile`
+- Update `docker-compose.yml` (or equivalent)
+
+## Files to Modify
+
+### Scala (Phase 1)
+- `src/main/scala/net/eagle0/eagle/service/AuthServiceImpl.scala` - Proxy OAuth RPCs to Go
+- `src/main/scala/net/eagle0/eagle/Main.scala` - Start internal user service, add auth-service-url flag
+
+### Scala (Phase 2 - Removal)
+- Delete `src/main/scala/net/eagle0/eagle/auth/OAuthService.scala`
+- Delete `src/main/scala/net/eagle0/eagle/service/OAuthHttpHandler.scala`
+- Simplify `src/main/scala/net/eagle0/eagle/Main.scala` - Remove HTTP server
+
+### Unity (Phase 2)
+- `Assets/Auth/OAuthManager.cs` - Point OAuth RPCs to Go service port
+- `Assets/EagleConnection.cs` - Add second channel for auth service
+
+## Key Implementation Details
+
+### State Management in Go
+```go
+type OAuthState struct {
+    Provider  string
+    CreatedAt time.Time
+}
+
+type OAuthResult struct {
+    Success  bool
+    UserInfo *ProviderUserInfo
+    Provider string
+    Error    string
+}
+
+var pendingOAuth   = sync.Map{} // state -> OAuthState
+var completedOAuth = sync.Map{} // state -> OAuthResult
+
+const stateExpiration = 10 * time.Minute
+
+// Background goroutine cleans expired states every minute
+func cleanupExpiredStates() {
+    ticker := time.NewTicker(1 * time.Minute)
+    for range ticker.C {
+        cutoff := time.Now().Add(-stateExpiration)
+        pendingOAuth.Range(func(key, value any) bool {
+            if value.(OAuthState).CreatedAt.Before(cutoff) {
+                pendingOAuth.Delete(key)
+            }
+            return true
+        })
+        // Similar for completedOAuth
+    }
+}
+```
+
+### JWT Creation in Go
+```go
+import "github.com/golang-jwt/jwt/v5"
+
+type EagleClaims struct {
+    jwt.RegisteredClaims
+    UserId      string `json:"userId"`
+    DisplayName string `json:"displayName"`
+    IsAdmin     bool   `json:"isAdmin"`
+}
+
+func CreateAccessToken(userId, displayName string, isAdmin bool) (string, error) {
+    claims := EagleClaims{
+        RegisteredClaims: jwt.RegisteredClaims{
+            ExpiresAt: jwt.NewNumericDate(time.Now().Add(7 * 24 * time.Hour)),
+            IssuedAt:  jwt.NewNumericDate(time.Now()),
+        },
+        UserId:      userId,
+        DisplayName: displayName,
+        IsAdmin:     isAdmin,
+    }
+
+    token := jwt.NewWithClaims(jwt.SigningMethodRS256, claims)
+    return token.SignedString(privateKey)
+}
+```
+
+### OAuth Provider Configs
+- Read from environment variables (same as current OAuthConfig.scala)
+- DISCORD_CLIENT_ID, DISCORD_CLIENT_SECRET
+- GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET
+- OAUTH_CALLBACK_URL (e.g., https://eagle0.shardok.games/oauth/callback)
+
+### Container Networking
+```yaml
+# docker-compose.yml example
+services:
+  eagle0-auth:
+    build:
+      context: .
+      dockerfile: ci/auth_service.Dockerfile
+    ports:
+      - "40033:40033"  # gRPC
+      - "8080:8080"    # HTTP callback
+    volumes:
+      - ./keys:/etc/eagle0/keys:ro
+    environment:
+      - DISCORD_CLIENT_ID
+      - DISCORD_CLIENT_SECRET
+      - GOOGLE_CLIENT_ID
+      - GOOGLE_CLIENT_SECRET
+      - EAGLE_INTERNAL_URL=eagle0-server:40034
+
+  eagle0-server:
+    build:
+      context: .
+      dockerfile: ci/eagle_run.Dockerfile
+    ports:
+      - "40032:40032"  # Public gRPC
+    expose:
+      - "40034"        # Internal gRPC (container-to-container only)
+    volumes:
+      - ./keys:/etc/eagle0/keys:ro
+      - ./data:/var/lib/eagle0
+    environment:
+      - AUTH_SERVICE_URL=eagle0-auth:40033
+```
+
+## Deployment
+
+### Development
+```bash
+# Terminal 1: Go Auth Service
+bazel run //src/main/go/net/eagle0/authservice:authservice -- \
+  --grpc-port=40033 \
+  --http-port=8080 \
+  --eagle-internal-url=localhost:40034
+
+# Terminal 2: Eagle Server
+bazel run //src/main/scala/net/eagle0/eagle:eagle_server -- \
+  --eagle-grpc-port=40032 \
+  --internal-grpc-port=40034 \
+  --auth-service-url=localhost:40033
+```
+
+### Production
+- Both containers on same droplet via docker-compose
+- Shared volume for RSA keys at /etc/eagle0/keys/
+- Internal Docker network for container-to-container communication
+- External access: 40032 (Eagle gRPC), 8080 (OAuth HTTP callback)
+
+## Testing Strategy
+
+1. **Unit tests for Go service**
+   - OAuth state management (expiration, cleanup)
+   - JWT creation matches Scala output (test with same keys)
+   - HTTP callback parsing
+
+2. **Integration tests**
+   - Go service ↔ Eagle internal gRPC
+   - Full OAuth flow with mock provider
+
+3. **Existing tests continue to pass**
+   - All Scala tests (JWT validation, user service)
+
+4. **End-to-end test**
+   - Spin up both containers
+   - Run OAuth flow through proxy
+
+## Risks and Mitigations
+
+| Risk | Mitigation |
+|------|------------|
+| Key file permissions | Shared volume with read-only mount |
+| State loss on Go restart | Document this (same as current Scala behavior); consider Redis later |
+| Clock skew affecting JWT | Both on same machine |
+| OAuth callback race | HTTP callback completes before gRPC poll |
+| Container networking | Use docker-compose for reliable internal DNS |
+| Proxy adds latency | Minimal (same machine), remove in Phase 2 |
+
+## Estimated Scope
+
+- **Phase 1**: ~500-700 lines Go, ~100 lines Scala changes, ~50 lines Docker config
+- **Phase 2**: ~50 lines Unity, deletion of ~300 lines Scala
+- **Phase 3**: Optional, separate decision
+
+## Alternative Considered: Move Everything to Go
+
+Could move UserService to Go as well, but:
+- UserService is tightly integrated with game persistence
+- Would require duplicating persistence layer
+- Not worth the complexity for now
+
+Keep UserService in Eagle, expose via internal gRPC.
+
+## Open Questions
+
+1. **HTTP callback routing**: Does the OAuth callback URL need to change, or can we route traffic from the existing URL to the new Go service?
+2. **Health checks**: Should we add health check endpoints for container orchestration?
+3. **Logging**: Should Go service log to same format/destination as Eagle?

+
+## 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.
+
+## Architecture
+
+```
+Unity Client                                          Eagle Server
+     |                                                      |
+     |  1. Click "Login with Discord/Google"                |
+     |  ------------------------------------------------->  |
+     |     GetOAuthUrl(provider) -> auth_url + state        |
+     |                                                      |
+     |  2. Open system browser -> OAuth consent             |
+     |  3. User authenticates with provider                 |
+     |  4. Redirect to eagle0://auth/callback?code=xxx      |
+     |                                                      |
+     |  5. ExchangeCode(code, state)                        |
+     |  ------------------------------------------------->  |
+     |     Exchange code with provider                      |
+     |     Fetch user info (id, email, avatar)              |
+     |     Create/update user record                        |
+     |     Issue JWT + refresh token                        |
+     |  <-------------------------------------------------  |
+     |     (jwt, refresh_token, user_info, is_new_user)     |
+     |                                                      |
+     |  6. [If new user] SetDisplayName(name)               |
+     |  ------------------------------------------------->  |
+     |                                                      |

+     |     Authorization: Bearer <jwt>                      |
+     |  ------------------------------------------------->  |
+```
+
+## 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):**
+```
+DISCORD_CLIENT_ID
+DISCORD_CLIENT_SECRET
+GOOGLE_CLIENT_ID
+GOOGLE_CLIENT_SECRET
+JWT_PRIVATE_KEY_PATH
+JWT_PUBLIC_KEY_PATH
+```
+
+### Phase 5: Testing
+
+**Unit tests:**
+- `JwtServiceSpec.scala` - Token creation/validation
+- `UserServiceSpec.scala` - Display name validation, uniqueness
+- `OAuthServiceSpec.scala` - OAuth flow with mocked providers
+
+**Integration tests:**
+- Full OAuth flow with mock provider
+- JWT validation in AuthorizationInterceptor
+- gRPC calls with valid/invalid tokens
+
+**Manual testing:**
+- [ ] Discord login (Windows, macOS)
+- [ ] Google login (Windows, macOS)
+- [ ] Deep link callback works
+- [ ] Display name validation
+- [ ] Session persistence across restarts
+- [ ] Token refresh

+## 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.

+# OAuth Implementation: Next Steps and Design
+
+## Executive Summary
+
+The OAuth implementation is functional but has several gaps that need addressing before it's production-ready. This document outlines the known issues, proposes a comprehensive user identity model, and provides a prioritized implementation plan.
+
+## Current State (Updated January 2026)
+
+### What Works ✅
+- Discord OAuth flow (server-mediated polling)
+- Google OAuth flow
+- JWT token generation and validation
+- User creation and display name setting
+- Auto-login with stored tokens
+- Basic game creation and play with OAuth users
+- Headshot fetching via public CDN (no auth required)
+- Logout button in lobby (preserves tokens for quick reconnect)
+- Environment (prod/qa) and user display in lobby
+- Game identity with userName = displayName (PR #4964 merged)
+
+### Known Issues
+
+#### 1. Game Identity Model Fragility (Deferred)
+**Status**: Accepted for now. PR #4964 merged with `userName = displayName`.
+
+**Current behavior**:
+- Games store `userNameToFactionId: Map[String, Int]`
+- For JWT users, this maps displayName → factionId
+- displayName is technically mutable (users could change it)
+- No migration path when displayName changes
+
+**Why this is acceptable**:
+1. We don't currently have a "change display name" feature
+2. The alternative (using userId) requires more extensive changes
+3. Can migrate to userId-based identity later if needed
+
+#### 2. In-Game Headshot Fetching ✅ FIXED
+**Solution**: Made the `eagle0-headshots` S3 bucket public and enabled CDN.
+- Client now fetches directly from `https://eagle0-headshots.sfo3.cdn.digitaloceanspaces.com/`
+- No authentication required
+- Works for both OAuth and Basic Auth users
+- Simpler architecture, no dependency on home Mac server
+
+#### 3. Logout from Lobby ✅ FIXED
+**Solution**: Added logout button to lobby UI (PR #4967).
+- Button disconnects from server and returns to connection screen
+- Intentionally does NOT clear OAuth tokens
+- Allows quick reconnect with same account without full OAuth flow
+
+#### 4. Display Name Uniqueness Not Enforced (Medium) - OPEN
+**Problem**: User was able to set displayName "nolen" when that name was already taken.
+
+**Root cause**: Unknown - needs investigation. Either:
+- The uniqueness check is buggy
+- The displayNameIndex wasn't populated correctly during user creation
+- Race condition during concurrent registrations
+
+#### 5. Admin Server Crashes ✅ FIXED
+**Solution**: PR #4964 sets `userName = displayName` for JWT users.
+
+#### 6. Intermittent "Expired" Errors During Login (Medium) - INVESTIGATING
+**Problem**: Users occasionally get "OAuth session expired" errors even when server logs show the callback succeeded.
+
+**Status**: Added diagnostic logging in PR #4974 to trace:
+- State creation in `getAuthUrl`
+- State lookup in `handleCallback`
+- Result lookup in `checkStatus`
+
+**Possible causes**:
+- State mismatch between client and server
+- Race condition in polling
+- Cleanup running at wrong time
+
+#### 7. Token Expiry Field Bug ✅ FIXED
+**Problem**: `CheckOAuthStatusResponse.expiresAt` was returning refresh token expiry (30 days) instead of access token expiry (7 days).
+
+**Solution**: Fixed in PR #4974 to calculate correct access token expiry.
+
+---
+
+## Proposed User Identity Model
+
+### Design Principles
+
+1. **Stable Internal Identity**: `userId` (UUID) is the only key used for persistent associations
+2. **Display Name is Cosmetic**: Can change without breaking game associations
+3. **Backwards Compatibility**: Basic Auth continues to work for local development
+4. **Multi-Provider Support**: Users can link Discord, Google, and future providers
+5. **Avatar Flexibility**: Use OAuth avatar by default, support custom uploads later
+
+### Data Model
+
+```
+User {
+  userId: String (UUID)           // Primary key, immutable, used for all internal references
+  displayName: String             // Unique, user-visible, mutable with migration
+  displayNameLower: String        // Case-insensitive uniqueness
+  email: String                   // Primary email for account recovery/linking
+  avatarUrl: String               // Current avatar URL
+  avatarData: bytes               // Cached avatar for offline/fast access (future)
+  oauthIdentities: [OAuthIdentity]
+  createdAt: Timestamp
+  lastLoginAt: Timestamp
+  isAdmin: Boolean
+}
+
+OAuthIdentity {
+  provider: String                // "discord", "google", etc.
+  providerUserId: String          // Provider's user ID
+  providerEmail: String           // Email from this provider
+  avatarUrl: String               // Avatar from this provider
+  linkedAt: Timestamp
+}
+```
+
+### Identity Resolution Strategy
+
+The key question: **What should `AuthorizationUtils.userName` return?**
+
+#### Option A: userName = displayName (Current PR #4964)
+- **Pro**: Human-readable in logs, game saves, debugging
+- **Con**: Breaks if displayName changes
+- **Migration**: None needed now, complex later
+
+#### Option B: userName = userId (Recommended)
+- **Pro**: Stable identity, displayName changes are safe
+- **Con**: UUIDs in logs are ugly, need display name lookup for UI
+- **Migration**: Cleaner long-term, but breaking change for any existing OAuth games
+
+#### Option C: Hybrid with Migration Support
+- **userName** = userId for new games
+- **Legacy lookup** for old games by displayName
+- **Display layer** resolves userId → displayName for UI
+
+**Recommendation**: Option B with a display name resolution layer. The ugliness in logs is acceptable for the stability it provides. Implement a `UserService.resolveDisplayName(identifier: String): String` that returns displayName for UUIDs or the identifier itself for legacy usernames.
+
+### Account Linking Strategy
+
+#### Automatic Linking (Future)
+When a user logs in with a new OAuth provider:
+1. Check if the provider email matches an existing user's email
+2. If match found, prompt: "An account exists with this email. Link accounts?"
+3. If confirmed, add new OAuthIdentity to existing user
+4. If declined, create separate account (different email required)
+
+#### Manual Linking (MVP)
+1. User logs in with primary account
+2. User goes to Settings → Linked Accounts
+3. User clicks "Link Discord" or "Link Google"
+4. OAuth flow adds new identity to current user
+
+### Avatar/Headshot Strategy
+
+#### Phase 1: OAuth Avatars (MVP)
+- Store `avatarUrl` from OAuth provider during login
+- Server proxies avatar requests to avoid CORS issues
+- Cache avatars locally with TTL
+
+#### Phase 2: Avatar Caching
+- Download avatar to local storage on login
+- Serve from local storage for reliability
+- Refresh periodically or on login
+
+#### Phase 3: Custom Avatars (Future)
+- Allow users to upload custom avatar
+- Store in S3/DO Spaces
+- Custom avatar overrides OAuth avatar
+
+---

+
+---
+
+## Technical Debt to Address
+
+1. **Context Propagation in Futures**: PR #4960 fixed `setDisplayName` and `getCurrentUser`, but audit all `Future` blocks that access `AuthorizationUtils`
+
+2. **Dual Auth Support**: The system supports both Basic Auth and JWT. Consider:
+   - Should Basic Auth be deprecated for production?
+   - Should it remain for local development only?
+   - How do Basic Auth users interact with OAuth users in the same game?
+
+3. **Token Refresh**: `RefreshToken` RPC throws UNIMPLEMENTED. Need to:
+   - Implement refresh token storage and validation
+   - Handle token refresh in client
+   - Consider refresh token rotation for security
+
+4. **Session Management**: No server-side session tracking. Consider:
+   - Track active sessions per user
+   - Allow "logout all devices"
+   - Detect concurrent logins
+
+---
+
+## Open Questions
+
+1. **What happens when a Basic Auth user and OAuth user have the same name?**
+   - Currently possible - Basic Auth doesn't check UserService
+   - Could cause confusion in games
+   - Solution: Require OAuth for multiplayer? Or namespace Basic Auth names?
+
+2. **Should displayName changes be allowed?**
+   - With userId-based identity, it's safe
+   - But could cause confusion ("who is this new player?")
+   - Consider: rate limit changes, show "formerly known as" temporarily
+
+3. **How to handle OAuth provider account deletion?**
+   - User deletes their Discord account
+   - Their Eagle0 account still exists
+   - They can't login unless they linked another provider
+   - Solution: Encourage linking multiple providers, or add email/password fallback
+
+4. **Admin impersonation with OAuth**
+   - Currently works via X-Impersonate-User header
+   - Should this use userId or displayName?
+   - Probably userId for stability

+# Shardok Latency Hiding Strategies
+
+## Problem Statement
+
+With Shardok running on Hetzner (Helsinki) and Eagle on DigitalOcean (US), the round-trip latency for human commands is ~200-400ms:
+
+```
+Human posts command:
+Unity → Eagle (DO) → Shardok (Hetzner) → Eagle (DO) → Unity
+         ~10ms         ~100ms              ~100ms        ~10ms
+                    Total: ~220ms round-trip
+```
+
+This latency is acceptable for AI turns (users watch animations anyway), but creates noticeable lag when humans post commands.
+
+---
+
+## Strategy 1: Client-Side Animation Masking
+
+### Concept
+
+Start animations immediately when the user clicks, before server confirmation arrives. The animation duration masks the network latency.
+
+### Implementation by Command Type
+
+**Movement Commands** (deterministic):
+- Client knows the destination hex and movement path
+- Start movement animation immediately on click
+- Server confirms the move (should always match)
+- If server rejects (invalid state), snap unit back to origin
+
+**Attack Commands** (RNG-dependent):
+- Show attack animation immediately (unit swings sword, fires arrow)
+- Wait for server to return dice roll result
+- Show damage numbers / hit effects when server responds
+- Animation typically takes 300-500ms, masking most of the latency
+
+**End Turn**:
+- Latency not noticeable (user expects transition delay)
+
+### Unity Implementation Sketch
+
+```csharp
+// In CommandHandler.cs
+public void OnCommandSelected(Command command) {
+    // Start animation immediately
+    if (command.Type == CommandType.Move) {
+        unitController.StartMoveAnimation(command.TargetHex);
+    } else if (command.Type == CommandType.Attack) {
+        unitController.StartAttackAnimation(command.TargetUnit);
+    }
+
+    // Send to server in parallel
+    connection.SendCommand(command, (response) => {
+        if (response.Success) {
+            // Animation continues, apply result
+            ApplyCommandResult(response);
+        } else {
+            // Rollback animation
+            unitController.CancelAnimation();
+            ShowError(response.ErrorMessage);
+        }
+    });
+}
+```
+
+### Pros
+- Simple implementation
+- No server-side changes
+- Works with existing architecture
+
+### Cons
+- Doesn't eliminate latency for attacks with RNG (must wait for dice roll)
+- Rollback needed if server rejects command (rare but possible)
+
+### Estimated Improvement
+- Movement: ~200ms latency hidden (feels instant)
+- Attacks: ~100-200ms hidden by animation, ~100ms visible wait for dice result
+
+---
+
+## Strategy 2: Split Shardok Architecture
+
+### Concept
+
+Run two Shardok instances:
+- **Shardok-Primary (DigitalOcean)**: Handles command processing, source of truth
+- **Shardok-AI (Hetzner)**: AI computation only
+
+Human commands go to the nearby Primary for low latency. AI computation uses the powerful Hetzner instance.
+
+### Architecture
+
+```
+                    Human commands (low latency ~20ms)
+Unity ←→ Eagle ←→ Shardok-Primary (DigitalOcean)
+                         ↓ state sync (when AI turn starts)
+                    Shardok-AI (Hetzner)
+                         ↑ AI command response
+```
+
+### How It Works
+
+**Human Turn:**
+1. Human posts command → Eagle → Shardok-Primary (DO)
+2. Primary processes command immediately (~10ms local)
+3. Primary streams result to client via Eagle (~10ms)
+4. **Total latency: ~20ms** (vs ~220ms current)
+
+**AI Turn:**
+1. When AI's turn starts, Primary sends game state snapshot to Hetzner
+2. Shardok-AI computes best command using full CPU power
+3. Shardok-AI returns command index to Primary
+4. Primary executes command locally and streams to client
+5. Repeat until AI turn ends
+
+### Protocol Changes
+
+```protobuf
+// New service for AI-only computation
+service ShardokAIService {
+    // Send game state, receive AI's chosen command
+    rpc GetAICommand(AICommandRequest) returns (AICommandResponse);
+}
+
+message AICommandRequest {
+    bytes game_state = 1;           // Serialized game state
+    int32 player_id = 2;            // Which AI player
+    repeated bytes available_commands = 3;  // Available command descriptors
+}
+
+message AICommandResponse {
+    int32 command_index = 1;        // Index into available_commands
+    int32 search_depth = 2;         // For debugging
+    double best_score = 3;          // For debugging
+}
+```
+
+### Shardok-Primary Requirements
+
+Shardok-Primary on DigitalOcean needs to:
+- Process all commands (human and AI)
+- Maintain authoritative game state
+- Serialize/deserialize game state for AI requests
+- Run on minimal CPU (command processing is fast)
+
+This is essentially the current Shardok, but without running the AI search.
+
+### Shardok-AI Requirements
+
+Shardok-AI on Hetzner needs to:
+- Receive game state snapshots
+- Run AI evaluation (IterativeDeepeningAI or MCTS)
+- Return best command index
+- No persistent state (stateless worker)
+
+### AI Turn Latency
+
+Each AI command has ~200ms network latency. This is acceptable because:
+1. User is watching animations anyway
+2. Natural pacing lets user observe AI decisions
+3. AI computation is fast on Hetzner's 16 cores
+
+For a typical AI turn with 5 commands: 5 × 200ms = 1 second network overhead, plus AI thinking time. With animations, this feels natural.
+
+### Implementation Phases
+
+**Phase 1: Add Shardok-Primary (minimal)**
+- Deploy existing Shardok container to DigitalOcean
+- Configure Eagle to use local Shardok for all commands
+- Human latency immediately improves
+
+**Phase 2: Add AI offload**
+- Implement `ShardokAIService` RPC
+- Shardok-Primary calls Hetzner for AI commands
+- Shardok-AI processes requests statelessly
+
+**Phase 3: Optimize**
+- Batch multiple AI actions if possible
+- Pre-warm Shardok-AI connection
+- Add fallback if Hetzner unavailable
+
+### Pros
+- Human command latency drops from ~220ms to ~20ms
+- AI still gets Hetzner's CPU power
+- Clear separation of concerns
+- Shardok-Primary can fall back to local AI if Hetzner unavailable
+
+### Cons
+- Two Shardok instances to maintain
+- State serialization overhead for AI requests
+- Each AI action has network round-trip (acceptable with animations)
+
+---
+
+## Comparison
+
+| Approach | Human Latency | AI Throughput | Complexity | Changes Required |
+|----------|---------------|---------------|------------|------------------|
+| Current | ~220ms | High | - | - |
+| Animation masking | ~220ms (perceived ~50ms) | High | Low | Unity only |
+| Split architecture | ~20ms | High | Medium | New RPC, two deployments |
+
+---
+
+## Recommendation
+
+**Phase 1 (now)**: Implement animation masking in Unity client
+- Quick win, no server changes
+- Improves perceived latency significantly for movement
+- Attacks still show dice animation while waiting
+
+**Phase 2 (future)**: Split architecture if animation masking insufficient
+- Only needed if users complain about attack latency
+- More complex but provides true low latency
+- Natural evolution of current architecture

+## Onboarding Sequence
+
+Shown to first-time players. Guides them through the basics of strategic and tactical gameplay.

+| 1 | `welcome` | Modal | Auto (game start) | Welcome to Eagle0 | Command your armies, recruit heroes, and conquer provinces in this turn-based strategy game.<br><br>Let's walk through the basics! |
+| 2 | `select_province` | Overlay | Completes on: `province_selected` | The Strategic Map | This is your kingdom. Each colored region is a province.<br><br>Tap a province you control (shown in your color) to see what you can do there. |
+| 3 | `province_panel` | Modal | Button click | Province Information | This panel shows province details: its name, terrain, any armies present, and the commands available to you.<br><br>Commands let you move troops, recruit heroes, and more. |
+| 4 | `try_march` | Overlay | Completes on: `command_issued` | Issue a Command | Try issuing a March command to move your army to an adjacent province.<br><br>Select a destination and confirm the order. |
+| 5 | `turn_cycle` | Modal | Button click | The Turn Cycle | Eagle0 uses simultaneous turns. All players give orders at the same time, then turns resolve together.<br><br>When all players are ready, the server processes everyone's commands and shows the results. |
+| 6 | `wait_for_battle` | Hidden | Completes on: `first_battle_available` | *(none)* | *(Invisible step - waits for a battle to become available)* |
+| 7 | `battle_intro` | Modal | Button click | Battle Time! | When armies collide, you'll fight tactical battles on a hex grid.<br><br>You command individual units - infantry, cavalry, archers, and heroes with special abilities. |
+| 8 | `enter_battle` | Overlay | Completes on: `battle_entered` | Enter the Battle | Tap the Battle button to enter tactical combat. |
+| 9 | `tactical_overview` | Modal | Button click | Tactical Combat | Each unit has movement points and attack power. Position your troops wisely!<br><br>Units attack adjacent enemies. Flanking (attacking from multiple sides) deals bonus damage. |
+| 10 | `move_unit` | Overlay | Completes on: `battle_action` | Move Your Units | Tap one of your units to select it, then tap a highlighted hex to move there.<br><br>Blue hexes show where you can move. |
+| 11 | `attack_enemy` | Overlay | Completes on: `battle_action` | Attack! | Move next to an enemy unit, then tap the enemy to attack.<br><br>Red highlights show valid attack targets. |
+| 12 | `end_turn` | Overlay | Completes on: `turn_ended` | End Your Turn | When you've moved all units or want to pass, tap End Turn.<br><br>The enemy will then take their turn. |
+| 13 | `complete` | Modal | Button click (no skip) | You're Ready! | You now know the basics of Eagle0!<br><br>Explore diplomacy, recruit powerful heroes, and conquer the realm. Good luck, commander! |
+
+### Notes on Onboarding Flow
+
+- Steps 1-5 cover strategic gameplay
+- Step 6 is invisible - just waits for a battle
+- Steps 7-12 cover tactical combat
+- Step 13 celebrates completion
+
+**Questions to consider:**
+- Should we skip tactical tutorial if player skips to first battle themselves?
+- Should there be a "skip all" option visible from step 1?
+- Is the step order correct for typical first-game flow?

+# Blue-Green Deployment Script for Eagle Server
+#
+# This script performs a zero-downtime deployment with state consistency:
+# 1. Create .deployment_in_progress marker (signals deployment started)
+# 2. Start the staging instance (green) with new image
+# 3. Run warmup/smoke tests against staging (warms JIT)
+# 4. Switch nginx to staging (zero downtime - users immediately route to staging)
+# 5. Stop the active instance (blue) - blocks until flush completes
+# 6. Create .flush_complete marker (signals disk state is fresh)
+#
+# The flush marker coordination ensures green never serves stale game data:
+# - When users reconnect to green and trigger lazy-load, the code checks for markers
+# - If .deployment_in_progress exists, lazy-load WAITS for .flush_complete
+# - Once blue's flush completes and marker is created, lazy-load proceeds with fresh data
+#
+# Key insight: nginx switches to green BEFORE blue stops, achieving zero downtime.
+# Users who trigger lazy-load during blue's shutdown will wait for the flush marker.
+#
+# Usage: ./deploy-blue-green.sh [NEW_IMAGE_TAG]
+#
+# Example:
+#   ./deploy-blue-green.sh latest
+#   ./deploy-blue-green.sh sha-abc123

+# 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:

+# Chance Nodes in MCTS for Shardok
+
+## Problem Statement
+
+### Current Behavior
+The current MCTS implementation uses a fixed roll (50th percentile) for all probabilistic outcomes during simulation. This creates several issues:
+
+1. **Binary success actions overvalued**: A START_FIRE command with 51% success is treated as always succeeding, making it appear better than it actually is.
+2. **Discontinuity at 50%**: Actions with 49% vs 51% success have dramatically different evaluations, when they should be similar.
+3. **Variable-outcome actions simplified**: Melee/archery attacks with damage ranges are evaluated at a single point rather than their full distribution.
+
+### Example Issue
+```
+START_FIRE with 51% success:
+- Current MCTS: Assumes always succeeds (roll = 50)
+- Reality: Succeeds 51% of time, fails 49% of time
+- Result: AI overvalues this action
+```
+
+### How Iterative Deepening Solves This
+The iterative deepening AI (see `AICommandEvaluator.cpp:352-393`) handles randomness correctly:
+
+```cpp
+// For actions with odds (binary success/fail):
+// 1. Evaluate success outcome with representative roll
+auto [successScore, successLookahead] = EvaluateWithRandomness(
+    ...,
+    std::make_shared<SequenceRandomGenerator>(std::vector{1.0 - successChance / 2.0})
+);
+
+// 2. Evaluate failure outcome with representative roll
+auto [failureScore, failureLookahead] = EvaluateWithRandomness(
+    ...,
+    std::make_shared<SequenceRandomGenerator>(std::vector{(1.0 - successChance) / 2.0})
+);
+
+// 3. Compute weighted average (expected value)
+immediateScore = std::lerp(failureScore, successScore, successChance);
+lookaheadScore = std::lerp(failureLookahead.get(), successLookahead.get(), successChance);
+```
+
+This is essentially an implicit form of chance nodes - evaluating both outcomes and weighting by probability.
+
+## Chance Nodes Concept
+
+### Classic MCTS with Chance Nodes
+
+In games with randomness (e.g., backgammon), MCTS uses two types of nodes:
+
+1. **Decision Nodes**: Player chooses an action
+   - Selection uses UCB formula (exploration/exploitation tradeoff)
+   - One child per legal action
+
+2. **Chance Nodes**: Nature determines outcome
+   - Selection uses expectation (weighted by probability)
+   - One child per possible outcome
+
+```
+Decision Node (Player to move)
+├─ Action A
+│  └─ Chance Node
+│     ├─ Outcome 1 (prob 0.3) → Game State
+│     ├─ Outcome 2 (prob 0.5) → Game State
+│     └─ Outcome 3 (prob 0.2) → Game State
+└─ Action B
+   └─ Deterministic → Game State
+```
+
+### Example: START_FIRE in Shardok
+
+**Current approach:**
+```
+State S
+└─ START_FIRE (roll=50)
+   └─ State S' (fire always starts)
+```
+
+**With chance nodes:**
+```
+State S
+└─ START_FIRE action
+   └─ Chance Node
+      ├─ Success (51%) → State S_success (fire started)
+      └─ Failure (49%) → State S_failure (no fire, vigor spent)
+```
+
+### Value Propagation
+
+**Decision nodes:** Maximize/minimize over children (depending on player)
+**Chance nodes:** Expected value over children (weighted by probability)
+
+```cpp
+// Decision node value (max for current player)
+value = max(child.value for child in children)
+
+// Chance node value (expectation)
+value = sum(prob[i] * child[i].value for i in outcomes)
+```
+
+## Implementation Approaches
+
+### Option 1: Explicit Chance Nodes (Full Implementation)
+
+Modify the MCTS tree structure to explicitly represent chance nodes.
+
+**Pros:**
+- Theoretically sound
+- Handles arbitrary outcome distributions
+- Clear separation of decision vs chance
+
+**Cons:**
+- Significant code changes
+- Larger tree (more memory)
+- More complex tree traversal
+
+**Tree Structure:**
+```cpp
+enum class NodeType { DECISION, CHANCE };
+
+struct MCTSNode {
+    NodeType type;
+
+    // For decision nodes
+    MCTSPlayerId player;
+    std::vector<std::unique_ptr<MCTSAction>> actions;
+    std::vector<std::unique_ptr<MCTSNode>> children;  // One per action
+
+    // For chance nodes
+    std::vector<double> probabilities;  // One per outcome
+    std::vector<std::unique_ptr<MCTSNode>> outcomes;  // One per outcome
+
+    double visits;
+    double totalReward;
+};
+```
+
+**Selection Phase:**
+```cpp
+MCTSNode* select(MCTSNode* node) {
+    while (!node->isLeaf()) {
+        if (node->type == DECISION) {
+            // Use UCB to select action
+            node = selectChildUCB(node);
+        } else {  // CHANCE node
+            // Use probability-weighted selection
+            node = selectOutcomeByProbability(node);
+        }
+    }
+    return node;
+}
+```
+
+**Backpropagation:**
+```cpp
+void backpropagate(MCTSNode* node, double reward) {
+    while (node != nullptr) {
+        node->visits++;
+        if (node->type == DECISION) {
+            node->totalReward += reward;  // Sum for averaging
+        } else {  // CHANCE node
+            node->totalReward += reward;  // Still sum, but averaged differently
+        }
+        node = node->parent;
+    }
+}
+```
+
+### Option 2: Implicit Chance Nodes (Hybrid Approach)
+
+Keep the current tree structure but sample outcomes during expansion/simulation.
+
+**Pros:**
+- Smaller code changes
+- More memory efficient
+- Easier to implement incrementally
+
+**Cons:**
+- Less theoretically pure
+- May need more visits to converge
+- Sampling introduces variance
+
+**Approach:**
+```cpp
+// During expansion
+std::unique_ptr<MCTSGameState> expand(
+    const MCTSGameState& state,
+    const MCTSAction& action
+) {
+    if (action.isDeterministic()) {
+        return applyActionDeterministic(state, action);
+    } else {
+        // Sample an outcome based on probabilities
+        auto outcome = sampleOutcome(action);
+        return applyActionWithOutcome(state, action, outcome);
+    }
+}
+```
+
+**For binary actions (e.g., START_FIRE):**
+```cpp
+// Expand creates one of two children based on sampling
+if (random() < successProbability) {
+    return applySuccess(state, action);
+} else {
+    return applyFailure(state, action);
+}
+
+// Over many visits, visit ratio will approach probability ratio
+// E.g., 51% success action will have ~51% success children, 49% failure children
+```
+
+### Option 3: Determinized Sampling (Simplest)
+
+Pre-sample all random outcomes at the start of each simulation rollout.
+
+**Pros:**
+- Minimal code changes
+- Easy to understand
+- Works with existing tree structure
+
+**Cons:**
+- May converge slowly
+- Doesn't explicitly represent probability
+- Can waste simulations on unlikely outcomes
+
+**Approach:**
+```cpp
+// At start of each simulation
+std::vector<double> rollSequence = generateRollSequence(maxDepth);
+
+// Use sequence during simulation
+auto state = rootState;
+for (int depth = 0; depth < maxDepth; depth++) {
+    auto action = selectAction(state);
+    state = applyAction(state, action, rollSequence[depth]);
+}
+```
+
+## Recommended Approach: Progressive Enhancement
+
+Implement in phases to manage complexity:
+
+### Phase 1: Binary Chance Nodes (Explicit)
+
+Start with actions that have clear success/failure outcomes (e.g., START_FIRE, EXTINGUISH_FIRE, RAISE_DEAD):
+
+1. Identify binary actions (commands with `HasOdds()`)
+2. Add chance node support for these actions only
+3. Modify tree expansion to create chance nodes
+4. Update selection/backpropagation for chance nodes
+
+**Implementation:**
+```cpp
+// In ShardokGameEngine::getLegalActions()
+// Mark which actions require chance nodes
+struct ActionMetadata {
+    std::unique_ptr<MCTSAction> action;
+    bool requiresChanceNode;
+    double successProbability;  // If requiresChanceNode = true
+};
+```
+
+```cpp
+// In tree expansion
+if (action.requiresChanceNode) {
+    // Create chance node with two children
+    auto chanceNode = std::make_unique<MCTSNode>(CHANCE);
+    chanceNode->probabilities = {successProb, 1.0 - successProb};
+
+    // Expand both outcomes
+    chanceNode->outcomes.push_back(applySuccess(state, action));
+    chanceNode->outcomes.push_back(applyFailure(state, action));
+
+    return chanceNode;
+} else {
+    // Normal deterministic expansion
+    return applyAction(state, action);
+}
+```
+
+### Phase 2: Multi-Outcome Actions
+
+Extend to actions with multiple outcomes (e.g., melee damage ranges):
+
+1. Discretize continuous distributions into buckets
+2. For melee/archery, use 3-5 representative damage values (min, low, avg, high, max)
+3. Compute probabilities for each bucket
+4. Create chance nodes with multiple children
+
+**Example: Melee Attack**
+```cpp
+// Instead of sampling full damage distribution,
+// use representative values
+struct DamageBucket {
+    int damageValue;  // Representative damage
+    double probability;  // Probability of this range
+};
+
+// For a melee attack that can deal 10-20 damage
+std::vector<DamageBucket> buckets = {
+    {10, 0.1},  // Min damage (unlucky)
+    {13, 0.2},  // Low damage
+    {15, 0.4},  // Average damage
+    {17, 0.2},  // High damage
+    {20, 0.1}   // Max damage (lucky)
+};
+```
+
+### Phase 3: Optimization
+
+Once chance nodes work correctly:
+
+1. Add transposition table support for chance nodes
+2. Optimize memory layout
+3. Consider progressive widening (start with 2 outcomes, expand to more if visited often)
+4. Profile and tune
+
+## Design Decisions
+
+### How to Represent Outcomes?
+
+**Option A: Explicit state copies**
+```cpp
+struct ChanceNode {
+    std::vector<std::unique_ptr<MCTSGameState>> outcomeStates;
+    std::vector<double> probabilities;
+};
+```
+
+**Option B: Lazy evaluation**
+```cpp
+struct ChanceNode {
+    MCTSGameState baseState;
+    MCTSAction action;
+    std::vector<int> outcomeRolls;  // Roll values for each outcome
+    std::vector<double> probabilities;
+
+    // Compute state on-demand
+    MCTSGameState getOutcome(size_t index) {
+        return applyActionWithRoll(baseState, action, outcomeRolls[index]);
+    }
+};
+```
+
+**Recommendation:** Option B - lazy evaluation. Only materialize states when visited.
+
+### How Many Outcomes per Action?
+
+**Binary actions (START_FIRE, etc.):**
+- Exactly 2 outcomes (success/fail)
+- Use exact probabilities from `GetOddsPercentile()`
+
+**Damage actions (MELEE, ARCHERY):**
+- Start with 3 outcomes (low/med/high)
+- Can expand to 5 if needed for accuracy
+- Use representative rolls: 10th, 50th, 90th percentile
+
+**Complex actions (METEOR):**
+- Consider 2-3 outcomes initially
+- Can model as "hits N enemies" for N in {0, 1, 2, 3+}
+
+### How to Handle Transposition Table?
+
+**Challenge:** Same state can be reached via different chance outcomes
+
+**Solution:**
+- Hash based on game state only (not the path taken)
+- When looking up, return cached evaluation if state matches
+- This is already how transposition tables work!
+
+```cpp
+// Current approach works fine:
+auto hash = computeHash(gameState);  // Doesn't include how we got here
+if (auto cached = transpositionTable.lookup(hash)) {
+    return cached->value;
+}
+```
+
+### Selection at Chance Nodes
+
+**During tree traversal:**
+```cpp
+size_t selectOutcome(const ChanceNode& node) {
+    // Option 1: Sample by probability (introduces variance)
+    double r = random();
+    double cumulative = 0.0;
+    for (size_t i = 0; i < node.probabilities.size(); i++) {
+        cumulative += node.probabilities[i];
+        if (r < cumulative) return i;
+    }
+
+    // Option 2: Round-robin weighted by visit count vs probability
+    // (Explore under-visited outcomes more)
+    size_t leastVisited = findMostUnderExploredOutcome(node);
+    return leastVisited;
+}
+```
+
+**Recommendation:** Use Option 2 to ensure all outcomes get explored proportionally.
+
+## Integration Points
+
+### Modified Functions
+
+1. **`ShardokGameEngine::getLegalActions()`**
+   - Add metadata about which actions need chance nodes
+   - Return action + probability information
+
+2. **`ShardokGameEngine::applyAction()`**
+   - For binary actions, return both possible outcomes
+   - Or: take an explicit outcome index parameter
+
+3. **`AbstractMCTSAI::selection()`**
+   - Handle chance nodes differently from decision nodes
+   - Use probability-weighted selection instead of UCB
+
+4. **`AbstractMCTSAI::expand()`**
+   - Create chance node children for probabilistic actions
+   - May create multiple child nodes per action
+
+5. **`AbstractMCTSAI::backpropagate()`**
+   - Update all nodes in path (both decision and chance)
+   - Value calculation already handles this correctly (just averages)
+
+### New Functions Needed
+
+```cpp
+// In ShardokGameEngine
+struct ChanceOutcome {
+    int roll;  // The dice roll that produces this outcome
+    double probability;  // Probability of this outcome
+};
+
+std::vector<ChanceOutcome> getChanceOutcomes(const MCTSAction& action) const;
+```
+
+```cpp
+// In MCTSNode
+bool isChanceNode() const;
+const std::vector<double>& getOutcomeProbabilities() const;
+```
+
+## Testing Strategy
+
+### Unit Tests
+
+1. **Binary action correctness**
+   ```cpp
+   TEST(ChanceNodes, BinaryActionExpectedValue) {
+       // START_FIRE with 60% success
+       // Run MCTS with chance nodes
+       // Verify: visits to success ~= 60%, visits to failure ~= 40%
+       // Verify: expected value matches manual calculation
+   }
+   ```
+
+2. **Comparison with iterative deepening**
+   ```cpp
+   TEST(ChanceNodes, MatchesIterativeDeepening) {
+       // Same position, both AIs
+       // Should choose same action
+       // Scores should be similar (within variance)
+   }
+   ```
+
+3. **Transposition table with chance**
+   ```cpp
+   TEST(ChanceNodes, TranspositionConsistency) {
+       // Two paths to same state via different chance outcomes
+       // Should reuse cached evaluation
+   }
+   ```
+
+### Integration Tests
+
+1. Compare MCTS with/without chance nodes on test positions
+2. Verify that chance nodes reduce overvaluation of marginal actions
+3. Performance test: measure slowdown (expect 1.5-2x for binary actions)
+
+### Real-World Validation
+
+Run the problematic START_FIRE scenario:
+- With current MCTS: Should overvalue START_FIRE
+- With chance nodes: Should correctly weight success/failure
+- Expected: END_TURN should get significantly more visits
+
+## Performance Considerations
+
+### Memory Overhead
+
+**Per chance node:**
+- Probability vector: `N * sizeof(double)` (N = number of outcomes)
+- Outcome children: `N * sizeof(unique_ptr)`
+- For binary: ~32 bytes per chance node
+
+**Estimate:**
+- Current tree: ~100K nodes per search
+- With chance nodes: ~150K nodes (50% actions are probabilistic)
+- Extra memory: ~50K * 32 bytes = ~1.6 MB
+- **Acceptable overhead**
+
+### Computational Overhead
+
+**Per simulation:**
+- Current: 1 path through tree
+- With chance nodes: Still 1 path, but more nodes
+- Overhead: ~20-30% (more node visits)
+
+**Mitigation:**
+- Transposition table helps (same states via different paths)
+- Progressive widening (start with 2 outcomes, expand if visited often)
+- Lazy state evaluation (don't materialize until needed)
+
+### Convergence Speed
+
+Chance nodes may require more visits to converge because:
+- More children per action (branching factor increases)
+- Outcomes need proportional exploration
+
+**Mitigation:**
+- Use visit count thresholds before expanding chance nodes
+- Consider progressive widening (UCT-ProgressiveWidening)
+
+## Migration Path
+
+### Step 1: Infrastructure (1-2 days)
+- Add `NodeType` enum and metadata to MCTSNode
+- Implement chance node creation (without using them yet)
+- Add unit tests for chance node structure
+
+### Step 2: Binary Actions (2-3 days)
+- Identify all binary success/fail actions
+- Modify expansion to create chance nodes for these
+- Update selection/backpropagation
+- Test on START_FIRE scenario
+
+### Step 3: Integration Testing (1 day)
+- Run full MCTS tests with chance nodes enabled
+- Compare with iterative deepening on test positions
+- Validate that it fixes the START_FIRE overvaluation
+
+### Step 4: Multi-Outcome Actions (2-3 days)
+- Implement damage bucketing for MELEE/ARCHERY
+- Create chance nodes with 3-5 outcomes
+- Test on combat scenarios
+
+### Step 5: Optimization (1-2 days)
+- Profile performance
+- Add progressive widening if needed
+- Tune outcome granularity
+
+### Step 6: Documentation & Cleanup (1 day)
+- Document the new approach
+- Clean up code
+- Add comprehensive tests
+
+## Alternative: Simpler Hybrid Approach
+
+If full chance nodes are too complex, consider a hybrid:
+
+1. **Keep current tree structure** (no explicit chance nodes)
+2. **During expansion:** Sample outcome and create one child
+3. **Over many simulations:** Statistics converge to correct probabilities
+4. **Add outcome tracking:** Store "which outcome" in edge/node metadata
+
+**Example:**
+```cpp
+// Expansion samples an outcome
+auto expand(state, action) {
+    if (action.hasBinaryOutcome()) {
+        // Sample once
+        bool success = (random() < successProb);
+        // Store which outcome this edge represents
+        edge.metadata.outcome = success ? OUTCOME_SUCCESS : OUTCOME_FAILURE;
+        return applyWithOutcome(state, action, success);
+    }
+}
+
+// Selection prioritizes under-explored outcomes
+auto selectChild(node) {
+    // Find action where outcome distribution is unbalanced
+    // E.g., 60% success action should have ~60% success children
+    // If we have 80% success children, prefer exploring failure
+}
+```
+
+This is simpler but less theoretically sound. It's a reasonable starting point if full chance nodes prove too complex.
+
+## Comparison: Chance Nodes vs Open-Loop MCTS
+
+### What is Open-Loop MCTS?
+
+**Open-loop MCTS** (also called "determinization MCTS" or "information set MCTS") is an alternative approach to handling randomness:
+
+1. At the **start of each simulation**, sample all random outcomes needed for that simulation
+2. Play out the entire simulation using those fixed random values
+3. Different simulations use different random seeds
+4. The tree structure doesn't explicitly model randomness - it's all in the rollouts
+
+**Example implementation:**
+```cpp
+// At start of simulation
+std::vector<double> rollSequence = sampleRolls(maxDepth);  // Pre-sample all rolls
+
+// During simulation
+MCTSNode* node = root;
+for (int depth = 0; depth < maxDepth; depth++) {
+    Action action = selectAction(node);
+    node = applyAction(node, action, rollSequence[depth]);  // Use pre-sampled roll
+}
+```
+
+### Open-Loop MCTS for Shardok
+
+**How it would work:**
+```cpp
+// Each simulation samples a "possible world"
+void simulate(MCTSNode* root) {
+    // Sample random rolls for this simulation
+    auto rolls = generateRollSequence();  // e.g., {0.45, 0.78, 0.23, ...}
+
+    // Play out simulation using these fixed rolls
+    auto state = root->state;
+    for (int depth = 0; depth < maxDepth; depth++) {
+        auto action = selectAction(state);
+        state = applyAction(state, action, rolls[depth]);
+    }
+
+    double reward = evaluate(state);
+    backpropagate(root, reward);
+}
+```
+
+**Would this fix the START_FIRE issue?**
+
+**Yes** - partially. Different simulations would see different outcomes:
+- Some simulations: START_FIRE succeeds (roll < 0.51)
+- Some simulations: START_FIRE fails (roll >= 0.51)
+- Over many simulations, the action's value would approach the expected value
+
+**However**, it's less efficient than chance nodes because:
+- Needs MORE simulations to converge
+- Wastes effort exploring unlikely scenarios equally with likely ones
+- Doesn't explicitly guide exploration based on probability
+
+### Detailed Comparison
+
+| Aspect | Chance Nodes (Closed-Loop) | Open-Loop MCTS | Current (Fixed Roll) |
+|--------|---------------------------|----------------|----------------------|
+| **Randomness Handling** | Explicit in tree structure | Implicit in simulation sampling | Fixed roll=50 |
+| **Convergence Speed** | Fast - probabilities guide search | Slower - needs more samples | N/A (wrong answer) |
+| **Memory Usage** | Higher (more nodes) | Lower (no extra nodes) | Lowest |
+| **Implementation Complexity** | High (tree structure changes) | Medium (sampling layer) | Low (current) |
+| **Theoretical Soundness** | Highest (models true game tree) | Medium (approximation via sampling) | Low (assumes fixed outcome) |
+| **START_FIRE Fix** | ✅ Yes, accurately | ✅ Yes, eventually | ❌ No |
+| **Efficiency** | Most efficient per simulation | Less efficient (wasted samples) | Efficient but wrong |
+| **Handles Hidden Information** | Poor | Excellent | N/A |
+
+### When to Prefer Each Approach
+
+**Prefer Chance Nodes when:**
+- Randomness outcomes are discrete and enumerable (e.g., binary success/fail)
+- Probabilities are known precisely
+- You want fastest convergence to correct answer
+- Game tree is the primary concern (no hidden information)
+- **This is Shardok's situation** ✅
+
+**Prefer Open-Loop when:**
+- Randomness is continuous and high-dimensional
+- Hidden information or imperfect information is present
+- Simplicity is paramount
+- You can afford many simulations
+- Used in games like poker, bridge, Skat
+
+### Why Chance Nodes are Better for Shardok
+
+1. **Discrete outcomes**: Most Shardok randomness is binary (success/fail) or small discrete sets (damage ranges)
+   - START_FIRE: 2 outcomes (success/fail)
+   - MELEE: Can bucket into 3-5 damage ranges
+   - Not continuous - perfect fit for chance nodes
+
+2. **Known probabilities**: We have exact probabilities from `GetOddsPercentile()`
+   - Chance nodes can use exact probabilities
+   - Open-loop just samples blindly
+
+3. **No hidden information**: Shardok is perfect information (all units visible to AI)
+   - Chance nodes' main weakness doesn't apply
+   - Open-loop's main strength doesn't help
+
+4. **Convergence matters**: Limited simulation budget
+   - Need to converge quickly
+   - Chance nodes achieve this better
+
+5. **Existing infrastructure**: We already have deterministic state transitions
+   - Adding chance nodes builds on what we have
+   - Open-loop would need different rollout structure
+
+### Performance Analysis
+
+**Chance Nodes:**
+```
+Time per simulation: 1.3x current
+Simulations needed: 10,000 to converge
+Total time: 13,000x units
+
+Memory: 1.5x current (extra chance nodes)
+```
+
+**Open-Loop:**
+```
+Time per simulation: 1.0x current (same as now)
+Simulations needed: 30,000 to converge (more variance)
+Total time: 30,000x units
+
+Memory: 1.0x current (no extra nodes)
+```
+
+**Result:** Chance nodes are **2.3x faster overall** despite being slower per simulation, because they converge with fewer simulations.
+
+### Hybrid Approach: Best of Both Worlds?
+
+Could we combine them?
+
+**Idea:** Use chance nodes for high-probability branches, open-loop for rare events
+```cpp
+if (probability > 0.1 && outcomeCount <= 5) {
+    // Use explicit chance node
+    createChanceNode(outcomes, probabilities);
+} else {
+    // Use open-loop sampling
+    sampleOutcome();
+}
+```
+
+**Verdict:** Probably not worth the complexity. Shardok's randomness is simple enough that chance nodes handle everything well.
+
+### Recommendation for Shardok
+
+**Use Chance Nodes**, specifically:
+
+1. **Phase 1:** Binary actions (START_FIRE, RAISE_DEAD, etc.)
+   - 2 outcomes, exact probabilities
+   - Biggest bang for buck
+
+2. **Phase 2:** Damage ranges (MELEE, ARCHERY)
+   - 3-5 buckets
+   - Still manageable
+
+3. **If needed:** Could fall back to open-loop for complex actions
+   - E.g., METEOR with many possible outcomes
+   - But likely unnecessary
+
+### Why Not Open-Loop?
+
+While open-loop would eventually fix the START_FIRE issue, it has significant downsides for Shardok:
+
+1. **Slower convergence**: Needs 2-3x more simulations
+2. **Doesn't leverage known probabilities**: We have exact odds, why ignore them?
+3. **Less interpretable**: Harder to debug why AI chose an action
+4. **Doesn't align with iterative deepening**: We want MCTS to match the proven algorithm
+
+The only advantage of open-loop (simplicity) is outweighed by chance nodes' efficiency and correctness.
+
+### Could We Use Current Approach + Better Sampling?
+
+**Idea:** Keep fixed rolls but use different rolls per simulation?
+
+```cpp
+// Instead of always roll=50
+double roll = random();  // Different each simulation
+```
+
+**Problem:** This is essentially open-loop without the tree!
+- Even slower to converge
+- Tree doesn't learn the outcome probabilities
+- Worst of both worlds
+
+**Verdict:** No, this doesn't help. If we're going to sample, do it properly (open-loop). Otherwise, use chance nodes.
+
+### Final Verdict
+
+**For Shardok, chance nodes are clearly superior:**
+
+- ✅ Faster convergence (2-3x vs open-loop)
+- ✅ Leverages exact probabilities
+- ✅ Perfect fit for discrete outcomes
+- ✅ Aligns with iterative deepening approach
+- ✅ Better debuggability and interpretability
+- ❌ More complex implementation (but manageable)
+
+Open-loop would be a fallback if chance nodes prove too difficult, but given the benefits and the bounded complexity (only binary and small discrete outcomes), chance nodes are the right choice.
+
+## Conclusion
+
+Implementing chance nodes will fix the overvaluation of marginal probabilistic actions like START_FIRE with 51% success. The recommended approach is:
+
+1. Start with **explicit chance nodes for binary actions**
+2. Use **lazy state evaluation** to minimize memory
+3. **Progressive enhancement** - binary first, then multi-outcome
+4. Compare with iterative deepening to validate correctness
+
+Expected benefits:
+- More accurate action evaluation
+- Better handling of probabilistic outcomes
+- Closer alignment with theoretical MCTS
+- Fixes the START_FIRE issue without tuning heuristics
+
+Expected costs:
+- ~20-30% slower per simulation (more nodes)
+- ~1-2MB extra memory
+- ~1-2 weeks development time
+
+The benefits significantly outweigh the costs for a more theoretically sound and accurate AI.
