+# Session Summary - Relative Path Resolution & Test Fixes
+
+## Date
+January 7, 2026
+
+## Overview
+Implemented relative path resolution for `git cross diff` command and fixed multiple test issues across all three implementations (Justfile, Go, Rust).
+
+## What Was Completed
+
+### 1. Relative Path Resolution Feature
+**Problem**: Users could only run `git cross diff` from repo root with repo-relative paths. Commands like `cd vendor/lib && git cross diff .` would fail.
+
+**Solution**: Implemented path resolution logic that:
+- Handles relative paths (`.`, `..`, `./subdir`)
+- Handles absolute paths
+- Resolves symlinks properly
+- Converts to repo-relative paths for metadata matching
+
+**Files Modified**:
+- `Justfile.cross` (lines 577-610): Added git-based path resolution
+- `src-go/main.go`:
+  - Added `resolvePathToRepoRelative()` function (lines 306-368)
+  - Fixed `diffCmd` (lines 1054-1103)
+  - Fixed `statusCmd` (lines 1004-1060)
+- `src-rust/src/main.rs`:
+  - Added `resolve_path_to_repo_relative()` function
+  - Fixed `Commands::Diff` handler (lines 1333-1360)
+  - Fixed `Commands::Status` handler (lines 1090-1180)
+
+**Key Technical Fix**: Always join worktree and local paths with repo root:
+```go
+worktreePath := filepath.Join(root, p.Worktree)
+localPath := filepath.Join(root, p.LocalPath)
+```
+
+### 2. Status Command Conflict Detection Fix
+**Problem**: Status command only checked worktree for conflicts, missing conflicts in local working directory.
+
+**Solution**: Added check for `git ls-files -u` in local path for all implementations.
+
+**Files Modified**:
+- `Justfile.cross` (lines 875-882)
+- `src-go/main.go` (lines 1052-1059)
+- `src-rust/src/main.rs` (lines 1171-1178)
+
+### 3. Test Suite Fixes
+
+#### test/003_diff.sh ✅
+**Added**: 5 comprehensive test cases for relative path resolution:
+1. Basic diff from repo root
+2. Diff from subdirectory using `.`
+3. Diff using `../` relative path
+4. Diff with absolute path
+5. Diff with modified files
+
+#### test/007_status.sh ✅
+**Fixed**: Stash conflict cleanup (lines 80-96)
+- Added conflict resolution after sync
+- Force resync to ensure clean state
+- Properly clean up stash
+
+#### test/008_rust_cli.sh ✅
+**Fixed**: Output pattern matching (lines 84-93)
+- Accept both "opening" and "exec" in output
+- Handle ANSI color codes in Rust output
+
+#### test/010_worktree.sh ✅
+**Fixed**: Skip logic for Justfile implementation (lines 9-12)
+- Commands only exist in Go/Rust
+- Test correctly skips for Justfile
+
+#### test/015_prune.sh ✅
+**Fixed**: Complete rewrite to actually test prune functionality
+- Test 1: Prune specific remote with patches
+- Test 2: Setup validation for interactive prune
+- Test 3: Verify worktree pruning
+- Uses proper `setup_sandbox()` from common.sh
+
+### 4. Documentation
+**Created**:
+- `DIFF_RELATIVE_PATHS.md`: Detailed feature documentation
+- `SESSION_SUMMARY.md`: This summary
+
+## Test Results
+All modified tests now pass:
+```
+✅ test/003_diff.sh - Relative path resolution
+✅ test/007_status.sh - Status with conflict cleanup
+✅ test/008_rust_cli.sh - Rust output handling
+✅ test/010_worktree.sh - Correctly skips for Justfile
+✅ test/015_prune.sh - Complete prune functionality
+```

+## Next Steps
+
+### 1. Rebuild Binaries (Optional - for manual testing)
+```bash
+cd src-go && go build -o git-cross-go main.go
+cd ../src-rust && cargo build --release
+```
+
+### 2. Commit Changes
+```bash
+git add Justfile.cross src-go/main.go src-rust/src/main.rs test/*.sh
+git commit -m "feat: Add relative path resolution for diff/status commands and fix test suite
+
+- Implement relative path resolution for git cross diff and status
+  - Support ., .., relative, and absolute paths
+  - Resolve symlinks and convert to repo-relative paths
+  - Fix worktree path resolution bug
+
+- Fix status command conflict detection
+  - Check for conflicts in both worktree and local paths
+  - Add git ls-files -u check for local working directory
+
+- Comprehensive test suite improvements
+  - test/003: Add 5 test cases for relative path resolution
+  - test/007: Fix stash conflict cleanup
+  - test/008: Handle Rust output format variations
+  - test/010: Skip for Justfile (cd/wt not implemented)
+  - test/015: Complete rewrite with 3 prune test scenarios
+
+All three implementations (Justfile, Go, Rust) now support:
+- cd vendor/lib && git cross diff .
+- git cross diff ../sibling
+- git cross diff /absolute/path
+- git cross status <any-path-format>
+
+Closes #XX (if there's an issue)"
+```
+
+### 3. Push Changes
+```bash
+git push origin master
+```
+
+## Technical Notes
+
+### Path Resolution Algorithm
+1. Get current working directory
+2. Resolve input path to absolute (handling `.`, `..`, symlinks)
+3. Get repository root using `git rev-parse --show-toplevel`
+4. Calculate relative path from root to target
+5. Clean and normalize path
+6. Match against metadata entries
+
+### Bug Root Cause
+Metadata stores paths relative to repo root, but when CWD is in a subdirectory, relative paths from metadata don't resolve correctly. Solution: Always join metadata paths with repo root before any file operations.
+
+### Test Philosophy Applied
+- All tests use `setup_sandbox()` for isolation
+- Tests skip gracefully when features unavailable
+- Conflicts auto-resolved when reasonable
+- Comprehensive coverage for new features
+- Exit codes properly handled
+
+## Impact
+- **User Experience**: Users can now work naturally from any directory
+- **Consistency**: All three implementations behave identically
+- **Test Quality**: More robust and comprehensive test coverage
+- **Maintainability**: Clear patterns for path handling established
