# Gemini 3 Handoff Document

**Date**: 2024-11-22
**Prepared by**: Claude (Sonnet 4.5)
**Previous agents**: Gemini 3 (interrupted), Claude 4.5, GPT-OSS 120

## TL;DR

Your work was interrupted and left ~112 uncommitted files scattered across the workspace. I've organized everything into 5 logical branches based on your original `branch_organization.md` plan. All branches are ready for review and merging.

## What Happened

1. You (Gemini 3) started work on multiple features simultaneously
2. You created `docs/internal/plans/branch_organization.md` outlining how to split the work
3. You were interrupted before completing the organization
4. Claude 4.5 and GPT-OSS 120 attempted to help but left things partially done
5. I (Claude Sonnet 4.5) completed the reorganization

## Current Branch State

```
master (0d18c521a1) ─┬─► feature/agent-ui-improvements (29931139f5)
                     ├─► infra/ci-test-overhaul (aa411a5d1b)

                     └─► backup/all-uncommitted-work-2024-11-22 (5e32a8983f)
```

Also preserved:
- `feature/debugger-disassembler` (2a88785e25) - Your original debugger work

## Recommended Merge Order

```
1. infra/ci-test-overhaul     # Sets up CI/test infrastructure
         ↓
2. test/e2e-dungeon-coverage  # Uses new test config
         ↓
3. feature/agent-ui-improvements  # Independent feature
         ↓
4. fix/overworld-logic        # Small fix
         ↓
5. chore/misc-cleanup         # Docs and misc (rebase first)
```

### Merge Commands

```bash
# 1. Merge CI infrastructure
git checkout master
git merge --no-ff infra/ci-test-overhaul -m "Merge infra/ci-test-overhaul: CI/CD and test infrastructure"

# 2. Merge dungeon tests
git merge --no-ff test/e2e-dungeon-coverage -m "Merge test/e2e-dungeon-coverage: Dungeon E2E test suite"

# 3. Merge agent UI
git merge --no-ff feature/agent-ui-improvements -m "Merge feature/agent-ui-improvements: Agent UI and tools"

# 4. Merge overworld fix
git merge --no-ff fix/overworld-logic -m "Merge fix/overworld-logic: Overworld test fixes"

# 5. Rebase and merge cleanup (may have conflicts)
git checkout chore/misc-cleanup
git rebase master
# Resolve any conflicts
git checkout master
git merge --no-ff chore/misc-cleanup -m "Merge chore/misc-cleanup: Documentation and cleanup"
```

---

## Potential Conflicts

### Between branches:
- `chore/misc-cleanup` touches `src/CMakeLists.txt` which other branches may also modify
- Both `infra/ci-test-overhaul` and `chore/misc-cleanup` touch documentation

### With master:
- If master advances, all branches may need rebasing
- The `CLAUDE.md` changes in `infra/ci-test-overhaul` should be reviewed carefully

---

## Untracked Files (Need Manual Decision)

These were NOT committed to any branch:

| File/Directory | Recommendation |
|----------------|----------------|
| `.tmp/` | **Delete** - Contains ZScreamDungeon embedded repo |
| `third_party/bloaty` | **Decide** - Should be submodule or in .gitignore |
| `CIRCULAR_DEPENDENCY_ANALYSIS.md` | **Delete** - Temporary analysis |
| `CIRCULAR_DEPENDENCY_FIX_REPORT.md` | **Delete** - Temporary report |
| `FIX_CIRCULAR_DEPS.patch` | **Delete** - Temporary patch |
| `debug_crash.lldb` | **Delete** - Debug artifact |
| `fix_dungeon_colors.py` | **Delete** - One-off script |
| `test_grpc_server.sh` | **Keep?** - Test utility |

### Cleanup Commands
```bash
# Remove temporary files
rm -f CIRCULAR_DEPENDENCY_ANALYSIS.md CIRCULAR_DEPENDENCY_FIX_REPORT.md
rm -f FIX_CIRCULAR_DEPS.patch debug_crash.lldb fix_dungeon_colors.py

# Remove embedded repos (careful!)
rm -rf .tmp/

# Add to .gitignore if needed
echo ".tmp/" >> .gitignore
echo "third_party/bloaty/" >> .gitignore
```

## Stash Contents (For Reference)

```bash
$ git stash list
stash@{0}: WIP on feature/ai-test-infrastructure
stash@{1}: WIP on feature/ai-infra-improvements
stash@{2}: Release workflow artifact path fix
stash@{3}: WIP on develop (Windows OpenSSL)
stash@{4}: WIP on feat/gemini-unified-fix
```

To view a stash:
```bash
git stash show -p stash@{0}
```

These may contain work that was already incorporated into the branches, or may have unique changes. Review before dropping.

## The Original Plan (For Reference)

Your original plan from `branch_organization.md` was:

1. `feature/debugger-disassembler` - ✅ Already had commit
2. `infra/ci-test-overhaul` - ✅ Now populated
3. `test/e2e-dungeon-coverage` - ✅ Now populated
4. `feature/agent-ui-improvements` - ✅ Now populated
5. `fix/overworld-logic` - ✅ Now populated
6. `chore/misc-cleanup` - ✅ Now populated

---

## UI Modernization Context

You also had `ui_modernization.md` which outlines the component-based architecture pattern. Key points:

- New editors should follow `DungeonEditorV2` pattern
- Use `EditorDependencies` struct for dependency injection
- Use `ImGuiWindowClass` for docking groups
- Use `EditorCardRegistry` for tool windows
- `UICoordinator` is the central hub for app-level UI

The agent UI improvements in `feature/agent-ui-improvements` should align with these patterns.

---

## Safety Net

If anything goes wrong, the backup branch has EVERYTHING:

```bash
# Restore everything from backup
git checkout backup/all-uncommitted-work-2024-11-22

# Or cherry-pick specific files
git checkout backup/all-uncommitted-work-2024-11-22 -- path/to/file
```

---

## Questions for You

1. Should `third_party/bloaty` be a git submodule?
2. Should `.tmp/` be added to `.gitignore`?
3. Are the stashed changes still needed, or can they be dropped?
4. Do you want PRs created for review, or direct merges?
