https://prod.eagle0.net/admin/

+### Pre-Commit Checklist
+
+**MANDATORY: Before running `git commit`, verify:**
+
+1. **If you modified any BUILD.bazel file:** Run `bazel run gazelle` and stage any changes it makes
+2. **If you modified C++ or C# files:** Run `clang-format -i` on the modified files
+3. **If you modified Scala files:** scalafmt will run automatically via pre-commit hook
+
+The pre-commit hook runs gazelle but only checks if it succeeds - it does NOT verify the BUILD files are in canonical format. The `gazelle_test` will fail if deps are not alphabetically sorted. **Always run gazelle manually after BUILD file changes.**

+### 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

-
-### What's Partially Done ⚠️
-
-| Component | Status | Details |
-|-----------|--------|---------|
-| Actions | **5/48 fully converted** | 19 more use protoless base classes but still have proto dependencies |
-| ActionResultT | **Trait exists** | Concrete implementation incomplete |
-
-### What's Outstanding ❌
-
-| Component | Priority | Details |
-|-----------|----------|---------|
-| 43 Actions | **High** | Still using proto imports/dependencies |
-| Legacy Utilities | **Medium** | Direct proto imports in utility classes |
-
----
-
-## Phase 1: ~~Create GameStateC~~ ✅ COMPLETE
-
-**Already done!** The Scala `GameState` model and converter exist:
-
-- `src/main/scala/net/eagle0/eagle/model/state/game_state/GameState.scala` - Case class with 22 fields
-- `src/main/scala/net/eagle0/eagle/model/proto_converters/game_state/GameStateConverter.scala` - Full bidirectional conversion
-
-```scala
-// GameState.scala - already exists with all fields:
-case class GameState(
-    gameId: GameId,
-    currentRoundId: RoundId,
-    currentPhase: RoundPhase,
-    currentDate: Option[Date],
-    actionResultCount: Int,
-    provinces: Map[ProvinceId, ProvinceT],
-    heroes: Map[HeroId, HeroT],
-    battalions: Map[BattalionId, BattalionT],
-    destroyedBattalions: Map[BattalionId, BattalionT],
-    factions: Map[FactionId, FactionT],
-    factionCommandCounts: Map[FactionId, Int],
-    killedHeroes: Map[HeroId, HeroT],
-    destroyedFactions: Map[FactionId, FactionT],
-    outstandingBattles: Vector[ShardokBattle],
-    battleCounter: Int,
-    deferredNotifications: Vector[NotificationT],
-    runStatus: RunStatus,
-    victor: Option[FactionId],
-    battalionTypes: Vector[BattalionType],
-    randomSeed: Long,
-    chronicleEntries: Vector[ChronicleEntry]
-)
-```
-
----
-
-## Phase 2: ~~Update EngineImpl~~ ✅ COMPLETE (PR #4563)
-
-### Objective
-Change EngineImpl to hold `GameState` (Scala model) internally instead of `GameState` (proto).
-
-### Completed Changes
-
-- EngineImpl now uses `net.eagle0.eagle.model.state.game_state.GameState` (Scala)
-- Engine trait updated to return Scala `GameState`
-- GameController, GamesManager, and AIClient updated to use Scala models
-- Converters called only at persistence/GRPC boundaries
-
-### Validation
-- [x] EngineImpl compiles with new types
-- [x] Engine operations work correctly
-- [x] All tests pass
-
----
-
-## Phase 3: ~~Update GameHistory~~ ✅ COMPLETE (PR #4576)
-
-### Objective
-GameHistory should work with Scala models internally, converting to/from proto only for persistence.
-
-### Completed Changes
-
-- `GameHistory.stateAfter(count: Int)` now returns Scala `GameState`
-- `GameHistory.sinceDate(date: Date)` now accepts Scala `Date`
-- `InMemoryHistory` and `PersistedHistory` updated to use converters at boundaries
-- Callers updated:
-  - `EngineImpl` - wraps with `GameStateConverter.toProto()` where proto needed
-  - `UnrequestedTextHandler` - same
-  - `HumanPlayerClientConnectionState` - imports converter
-  - `NewRoundAction` / `ChronicleEventGenerator` - uses Scala Date
-
-### Validation
-- [x] GameHistory compiles
-- [x] Game state persistence/retrieval works
-- [x] All 7 service tests pass
-- [x] NewRoundActionTest passes
-
----
-
-## Phase 4: ~~Complete ActionResultT Implementation~~ ✅ ESSENTIALLY COMPLETE
-
-### Assessment Results (2024-11)
-
-The ActionResultT infrastructure is **already 86% complete**:
-
-| Component | Status | Details |
-|-----------|--------|---------|
-| **ActionResultT trait** | ✅ Complete | Full interface with 27 fields |
-| **ActionResultC case class** | ✅ Complete | Concrete implementation |
-| **ActionResultTApplier** | ✅ Exists | Wraps proto applier for gradual migration |
-| **ActionResultProtoConverter** | ✅ Complete | Bidirectional toProto/fromProto |
-| **Actions using ActionResultT** | ✅ 51/59 (86%) | Only ~10 actions still use proto |
-
-### Remaining Proto Actions (~10)
-
-**DeterministicSingleResultAction subclasses:**
-- EndBattleRequestPhaseAction, EndBattleResolutionPhaseAction
-- EndFreeForAllBattleResolutionPhaseAction, EndFreeForAllBattleRequestPhaseAction
-- EndPleaseRecruitMePhaseAction, EndDefenseDecisionPhaseAction
-- PerformFoodConsumptionPhaseAction, PerformHostileArmySetupAction
-- UnaffiliatedHeroesChangedAction, NewYearAction
-
-**RandomSequentialResultsAction subclasses:**
-- PerformProvinceMoveResolutionAction, TruceTurnBackPhaseAction
-- PerformUnaffiliatedHeroesAction, PerformVassalCommandsPhaseAction
-- PerformVassalDefenseDecisionsAction, PerformReconResolutionAction
-- EndVassalCommandsPhaseAction, EndHandleRiotsPhaseAction
-- PerformProvinceEventsAction
-
-**DeterministicSequentialResultsAction subclasses:**
-- PrisonerExchangeAction, PerformForcedTurnBackAction, PerformHeroDeparturesAction
-
-### Decision
-
-These remaining actions will be converted as part of **Phase 5** alongside the GameState parameter migration. No separate Phase 4 work needed.
-
-### Validation
-- [x] All action result types have Scala models
-- [x] Converter handles all cases
-- [x] ActionResultTApplier exists for gradual migration
-
----
-
-## Phase 5: Convert Actions & RoundPhaseAdvancer
-
-### Objective
-Convert actions to accept Scala `GameState`, then convert `RoundPhaseAdvancer` to orchestrate with Scala models throughout.
-
-### Strategic Insight
-
-`RoundPhaseAdvancer` is the central orchestrator that calls all phase-handling actions. Currently:
-- It receives proto `GameState` (converted from Scala in EngineImpl)
-- ~13 actions take proto `GameState` directly
-- ~6 actions already take individual Scala model parameters (protoless)
-- Inline conversions exist to bridge proto→Scala for protoless actions
-
-**Key win**: Converting actions called by RoundPhaseAdvancer enables converting RoundPhaseAdvancer itself, eliminating all inline conversions.
-
-### Recommended Tiers
-
-**Tier 1 - RoundPhaseAdvancer Actions (HIGH PRIORITY):**
-
-These 13 actions are called directly from RoundPhaseAdvancer with proto `GameState`:
-```
-NewRoundAction
-PrisonerExchangeAction
-PerformProvinceEventsAction
-PerformForcedTurnBackAction
-PerformProvinceMoveResolutionAction
-EndHandleRiotsPhaseAction
-PerformHeroDeparturesAction
-PerformUnaffiliatedHeroesAction
-EndPleaseRecruitMePhaseAction
-PerformVassalCommandsPhaseAction / EndVassalCommandsPhaseAction
-PerformFoodConsumptionPhaseAction
-EndDefenseDecisionPhaseAction
-TruceTurnBackPhaseAction
-PerformReconResolutionAction
-EndBattleResolutionPhaseAction / EndFreeForAllBattleResolutionPhaseAction
-RequestFreeForAllBattlesAction / EndFreeForAllBattleRequestPhaseAction
-PerformHostileArmySetupAction
-PerformVassalDefenseDecisionsAction
-```
-
-Target: Convert each to accept Scala `GameState` parameter.
-
-**Tier 2 - RoundPhaseAdvancer Itself:**
-
-Once Tier 1 is complete:
-```
-src/main/scala/net/eagle0/eagle/library/RoundPhaseAdvancer.scala
-```
-
-Changes:
-1. Accept Scala `GameState` instead of proto
-2. Pattern match on Scala `RoundPhase` sealed trait (cleaner than proto enum)
-3. Remove all inline converter calls (no more `ProvinceConverter.fromProto`, etc.)
-4. Convert to proto only when calling `ActionResultProtoApplier.applyActionResults`
-
-**Tier 3 - Remaining Actions:**
-
-Other actions not called from RoundPhaseAdvancer:
-- Command actions, battle resolution, etc.
-- Can be converted incrementally after Tier 2
-
-### Pattern for Conversion
-
-**Before (proto-dependent):**
-```scala
-class SomeAction(gameState: GameState) extends ProtolessSimpleAction {
-  def apply(): ActionResultT = {
-    val faction = gameState.factions(factionId)  // proto access
-    // ...
-  }
-}
-```
-
-**After (Scala GameState):**
-```scala
-class SomeAction(gameState: GameState) extends ProtolessSimpleAction {
-  // Now using: import net.eagle0.eagle.model.state.game_state.GameState
-  def apply(): ActionResultT = {
-    val faction = gameState.factions(factionId)  // Scala model access
-    // ...
-  }
-}
-```
-
-### Files to Modify
-```
-src/main/scala/net/eagle0/eagle/library/RoundPhaseAdvancer.scala
-src/main/scala/net/eagle0/eagle/library/actions/impl/action/*.scala
-```
-
-### Validation
-- [ ] Each converted action compiles
-- [ ] Each converted action passes its tests
-- [ ] RoundPhaseAdvancer works with Scala GameState
-- [ ] No inline converter calls in RoundPhaseAdvancer
-- [ ] EngineImpl no longer converts to proto before calling RoundPhaseAdvancer
-
----
-
-## Phase 6: Clean Up Legacy Utilities
-
-### Objective
-Remove direct proto imports from utility classes.
-
-### Files to Modify
-
-#### 6.1 LegacyFactionUtils.scala
-```
-src/main/scala/net/eagle0/eagle/library/LegacyFactionUtils.scala
-```
-- Replace `import net.eagle0.eagle.internal.faction.Faction` with `FactionT`
-- Update method signatures
-
-#### 6.2 LegacyUnaffiliatedHeroUtils.scala
-```
-src/main/scala/net/eagle0/eagle/library/LegacyUnaffiliatedHeroUtils.scala
-```
-- Replace proto imports with Scala model imports
-- Update method signatures
-
-#### 6.3 BattalionTypeLoader.scala
-```
-src/main/scala/net/eagle0/eagle/library/BattalionTypeLoader.scala
-```
-- Keep proto usage for file loading (persistence boundary)
-- Convert immediately to Scala model after load
-
-#### 6.4 BeastUtils.scala
-```
-src/main/scala/net/eagle0/eagle/library/BeastUtils.scala
-```
-- Replace proto BeastInfo with Scala model (if one exists, otherwise create)
-
-### Validation
-- [ ] No proto imports in utility files (except for persistence/serialization)
-- [ ] All utilities work correctly with Scala models
-
----
-
-## Phase 7: Verify GRPC Boundary
-
-### Objective
-Confirm that protos are used correctly at the GRPC boundary — and ONLY there.
-
-### Files to Review
-
-#### 7.1 EagleServiceImpl.scala
-```
-src/main/scala/net/eagle0/eagle/service/EagleServiceImpl.scala
-```
-
-**Correct Pattern:**
-```scala
-// Receive proto from client
-def postCommand(request: PostCommandRequest): Future[PostCommandResponse] = {
-  // Convert to Scala model
-  val command = CommandConverter.fromProto(request.command)
-
-  // Process with Scala models
-  val result = engine.processCommand(command)
-
-  // Convert back to proto for response
-  PostCommandResponse(ActionResultConverter.toProto(result))
-}
-```
-
-**This file SHOULD have proto imports** — it's the boundary.
-
-### Validation
-- [ ] GRPC service converts proto ↔ Scala at the boundary
-- [ ] No proto types leak into engine internals
-- [ ] No Scala model types leak into GRPC responses
-
----
-
-## Rollout Strategy
-
-### Approach: Incremental, Always-Green
-
-Each phase should result in a **buildable, testable** state. Never have a broken build.
-
-```
-Phase 1 (GameStateC) ──→ PR ──→ Merge ✅ (already existed)
-         │
-         ↓
-Phase 2 (EngineImpl) ──→ PR #4563 ──→ Merge ✅
-         │
-         ↓
-Phase 3 (GameHistory) ──→ PR #4576 ──→ Merge ✅
-         │
-         ↓
-Phase 4 (ActionResult) ──→ ✅ Already complete (86% of actions use ActionResultT)
-         │
-         ↓
-Phase 5 (Actions - batched) ──→ PRs ──→ Merge  ← NEXT
-         │
-         ↓
-Phase 6 (Utilities) ──→ PR ──→ Merge
-         │
-         ↓
-Phase 7 (Verification) ──→ PR ──→ Merge
-```
-
-### Testing Strategy
-
-1. **Unit Tests**: Each converter should have round-trip tests
-2. **Integration Tests**: Engine operations should produce correct results
-3. **Regression Tests**: Existing game scenarios should work identically
-
-### Rollback Plan
-
-If issues arise:
-- Each phase is a separate PR
-- Can revert individual PRs without affecting others
-- Converters provide backward compatibility during transition
-
----
-
-## Success Criteria
+This document tracks the migration from protobuf types to native Scala models inside the Eagle game engine.
 
-### 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
+## Architectural Decisions
 
-### Functionality
-- [ ] All existing tests pass
-- [ ] Game behavior unchanged
-- [ ] Performance within acceptable bounds
+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
 
-### Architecture
-- [ ] Clear separation: Scala models (internal) vs Proto (boundaries)
-- [ ] Converters as the only bridge between domains
-- [ ] No "proto creep" into business logic
+## Recent Completed Work
 
----
+### GameState Round-Trip Elimination (PRs #4913, #4914, #4915)
 
-## Appendix A: File Inventory
+Eliminated wasteful Scala→proto→Scala conversions in the hot path:
 
-### Proto Files (Keep - for serialization)
-```
-src/main/protobuf/net/eagle0/eagle/internal/game_state.proto
-src/main/protobuf/net/eagle0/eagle/internal/action_result.proto
-src/main/protobuf/net/eagle0/eagle/internal/hero.proto
-... (all .proto files)
-```
+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`).
 
-### Scala Models (Complete)
-```
-src/main/scala/net/eagle0/eagle/model/state/
-├── army/Army.scala ✅
-├── battalion/BattalionT.scala ✅
-├── faction/FactionT.scala ✅
-├── hero/HeroT.scala ✅
-├── province/ProvinceT.scala ✅
-├── game_state/GameState.scala ✅
-└── ... (43 total)
-```
+2. **ActionWithResultingState Caching** (#4914): Added `precomputedScalaState: Option[GameState]` to cache Scala state when available, avoiding `fromProto()` conversion in `stateAfter()`.
 
-### Converters (Complete)
-```

-└── ... (43 total)
-```
+3. **PostResults Simplification** (#4915): Changed `PostResults.gameState` from proto to `Option[GameState]` (Scala), eliminating `toProto()` calls when creating PostResults.
 
-### Actions (Convert)
-```
-src/main/scala/net/eagle0/eagle/library/actions/

-├── HeroBackstoryUpdateAction.scala ✅ (converted)
-├── NewRoundAction.scala ❌ (needs conversion)
-├── ResolveBattleAction.scala ❌ (needs conversion)
-└── ... (48 total, 43 need conversion)
-```
+## Migration Pattern
 
----
+The codebase follows a **Legacy* pattern** for separating proto-dependent and protoless code:
 
-## Appendix B: Estimated Effort
+- **Protoless utilities**: `FactionUtils`, `HeroUtils`, `ProvinceUtils`, `ProvinceDistances`, etc.
+- **Proto-dependent utilities**: `LegacyFactionUtils`, `LegacyHeroUtils`, `LegacyProvinceUtils`, `LegacyProvinceDistances`, etc.
 
-| Phase | Files | Lines Changed | Complexity | Status |
-|-------|-------|---------------|------------|--------|
-| Phase 1 | ✅ | 0 | Complete | **DONE** |
-| Phase 2 | 10 | ~200 | High | **DONE** (PR #4563) |
-| Phase 3 | 18 | ~200 | Medium | **DONE** (PR #4576) |
-| Phase 4 | ✅ | 0 | Already complete | **DONE** (86% of actions already use ActionResultT) |
-| Phase 5 | ~25 | ~2000 | Medium | Next (remaining ~10 actions + RoundPhaseAdvancer) |
-| Phase 6 | 4-6 | ~300 | Low | |
-| Phase 7 | 1-2 | ~50 | Low | |
-| **Total** | **~35** | **~2750** | | **~40% complete** |
+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
 
-## Appendix C: Open Questions
+### Fully Protoless (no proto imports)
 
-1. ~~**GameState size**: Already resolved - using single case class with 22 fields.~~
+**Utilities:**
+- [x] `FactionUtils` - has protoless `ownedNeighbors` method
+- [x] `ProvinceDistances` - split into protoless + `LegacyProvinceDistances`
+- [x] `SwornBrotherChooser` - fully protoless (removed `bestChoiceProto`)
 
-2. **Mutable vs Immutable**: Currently using immutable case classes with `copy`. Is this performant enough for game state updates?
+**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`
 
-3. **Shardok Integration**: `ResolveBattleAction` communicates with Shardok. Should the Shardok interface use protos (external service) or Scala models?
+**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`
 
-4. **View Generation**: `GameStateViewDiffer` works with view protos for client updates. Should views also have Scala models, or is proto acceptable for client-facing projections?
+### Fully Protoless
 
-5. **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?
+- [x] `AIClientUtils` - has protoless overloads (`takenHeroIdsForMarchTowardFocus`, `mostPowerfulHeroes`)
+- [x] `ProvinceGoldSurplusCalculator` - fully protoless (callers use converters)
+- [x] `HeroSelector` - fully protoless (removed dead `minimallyFatiguedHeroesProto`)
 
----
+### Blocked (still uses proto GameState)
 
-## Appendix D: Lessons Learned (from Phases 2-3)
+- [ ] `CommandChoiceHelpers` - main target, uses proto GameState extensively
+  - Depends on many Legacy* utils
+  - Central hub called by many command selectors
+- [ ] `AttackDecisionCommandChooser` - uses proto GameState, converts internally
+- [ ] `CommandChooser` - trait uses proto GameState in signature
+- [ ] `FulfillQuestsCommandSelector` - takes proto, converts to native immediately
+  - Called by `MidGameAIClient` which uses proto GameState
 
-### What Worked Well
+## Next Steps
 
-1. **Incremental approach** - Each phase produces a working build. Tests catch issues immediately.
+### Phase 1: CommandChoiceHelpers Migration
 
-2. **Converter pattern** - Having `GameStateConverter.toProto()`/`fromProto()` allows gradual migration. Callers can convert at their boundaries without changing everything at once.
+The main blocker is `CommandChoiceHelpers.scala` which uses proto `GameState` extensively. Strategy:
 
-3. **Type aliases help readability** - Using `import ... as DateProto` and `import ... as ScalaDate` makes the code clearer when both types coexist during migration.
+1. **Add Scala overloads** to `CommandChoiceHelpers` methods that currently take proto GameState
+2. **Update internal helpers** to use Scala types where possible
+3. **Migrate callers incrementally** - command selectors that are already protoless can switch to Scala overloads
 
-### Challenges Encountered
+### Phase 2: CommandChooser Trait
 
-1. **Test mock expectations need updating** - When a method's return type changes (e.g., `stateAfter` returning Scala GameState instead of proto), all mock expectations need to match the new type. This can cascade through many test files.
+Once CommandChoiceHelpers is protoless:
 
-2. **ActionWithResultingState still uses proto internally** - The `ActionWithResultingState` case class contains proto `GameState` and `ActionResult`. This means callers sometimes need to convert even when we'd prefer not to. Consider converting this class in a future phase.
+1. Add Scala `GameState` overload to `CommandChooser.choose()` method
+2. Update implementations (`AttackDecisionCommandChooser`, etc.) to use Scala internally
+3. Eventually deprecate proto overloads
 
-3. **Build file dependencies** - Each source file change may require BUILD.bazel updates for new imports. Running `bazel run gazelle` helps but manual review is sometimes needed.
+### Phase 3: MidGameAIClient
 
-### Recommendations for Future Phases
+The top-level AI client still uses proto GameState. Once lower layers are protoless:
 
-1. **Run tests early and often** - Build failures reveal type mismatches quickly. Fix one file at a time rather than trying to change everything before testing.
+1. Convert `MidGameAIClient` to use Scala GameState internally
+2. Only convert at the boundary when receiving from/sending to gRPC
 
-2. **Update tests alongside source** - When changing a trait's return type, update the tests for that trait's implementations in the same PR.
+## Key Files
 
-3. **Consider deferring ActionWithResultingState conversion** - This is used in the event-sourcing history and may be better left as proto until we're ready to migrate persistence format.
+### Protoless Model Types
+
+- `src/main/scala/net/eagle0/eagle/model/state/game_state/GameState.scala` - native Scala GameState
+- `src/main/scala/net/eagle0/eagle/model/state/province/ProvinceView.scala` - province view type
+- `src/main/scala/net/eagle0/eagle/model/state/faction/FactionView.scala` - faction view type
+- `src/main/scala/net/eagle0/eagle/model/state/hero/HeroView.scala` - hero view type
+
+### Proto Converters
+
+- `src/main/scala/net/eagle0/eagle/model/proto_converters/game_state/` - converts between proto and Scala types
+
+## Notes
+
+- The AI client code (`src/main/scala/net/eagle0/eagle/ai/`) currently uses proto types extensively
+- `PerformUnaffiliatedHeroesAction` already uses protoless `GameState`
+- Migration should proceed incrementally: utilities first, then higher-level selectors/choosers

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

+# 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]       │
+├─────────────────────────────────────────────────────────────┤
+│                                                             │

+│  └─────────────────────────────────────────────────────┘   │
+│                                                             │
+│  ┌─────────────────────────────────────────────────────┐   │
+│  │ BaseFoodBuyPrice (Double)                            │   │
+│  │ Current: [0.5   ] Default: 0.5             [Save]    │   │

+└─────────────────────────────────────────────────────────────┘
+```
+
+### 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       │

+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?

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

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

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

+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:
