+# GitHub Actions Workflows
+
+## Auto-update Dependencies
+
+**File:** `auto-update-dependencies.yml`
+
+### Purpose
+Automatically monitors and updates PKL and pkl-go dependencies to their latest versions.
+
+### Schedule
+- **Automatic:** Daily at 00:00 UTC
+- **Manual:** Can be triggered via GitHub Actions UI
+
+### What It Updates
+
+#### PKL
+- Source: [apple/pkl](https://github.com/apple/pkl) releases
+- Files updated:
+  - `versions.json` - PKL version reference
+  - `build.gradle.kts` - Gradle plugin version
+  - All `.pkl` files - `minPklVersion` in `@ModuleInfo`
+  - Dependencies and embedded assets
+
+#### pkl-go
+- Source: [apple/pkl-go](https://github.com/apple/pkl-go) releases
+- Files updated:
+  - `versions.json` - pkl-go version reference
+  - `go.mod` and `go.sum` - Go module dependencies
+  - Dependencies and embedded assets
+
+### Workflow Steps
+
+1. **Check for Updates**
+   - Fetches latest releases from GitHub API
+   - Compares with current versions in `versions.json`
+   - Determines if updates are needed
+
+2. **Apply Updates** (if needed)
+   - Updates `versions.json`
+   - Updates `go.mod` (for pkl-go)
+   - Updates `build.gradle.kts` (for PKL)
+   - Updates all `.pkl` files with new `minPklVersion`
+   - Runs dependency download scripts
+   - Updates import paths
+   - Regenerates embedded assets
+
+3. **Run Tests**
+   - Executes Go tests to verify compatibility
+   - Ensures no breaking changes
+
+4. **Create Pull Request**
+   - Generates detailed PR with changelog
+   - Includes release notes links
+   - Adds labels: `dependencies`, `autoupdate`
+
+### Manual Trigger
+
+To manually trigger the workflow:
+
+1. Go to Actions tab in GitHub
+2. Select "Auto-update Dependencies"
+3. Click "Run workflow"
+4. Select branch (usually `main`)
+5. Click "Run workflow"
+
+### PR Format
+
+**Title:**
+```
+chore: auto-update pkl to X.X.X and pkl-go to X.X.X
+```
+
+**Labels:**
+- `dependencies`
+- `autoupdate`
+
+**Body includes:**
+- Version changes summary
+- List of all modified files
+- Links to release notes
+- Test results
+
+### Troubleshooting
+
+**Workflow fails at dependency download:**
+- Check network connectivity in GitHub Actions
+- Verify GitHub API rate limits
+- Check if pkl/pkl-go repositories are accessible
+
+**Tests fail after update:**
+- Review the PR to see what changed
+- Check release notes for breaking changes
+- May need manual intervention to fix compatibility
+
+**No PR created despite new versions:**
+- Check workflow logs for errors
+- Verify `GITHUB_TOKEN` has proper permissions
+- Ensure `versions.json` format is correct
+
+### Dependencies
+
+The workflow requires:
+- Ubuntu latest runner
+- Go 1.24.4+
+- Java 21 (Temurin)
+- Gradle (via setup-gradle action)
+- jq (for JSON parsing)
+- pkl CLI (downloaded during workflow)
+
+### Permissions Required
+
+```yaml
+permissions:
+  contents: write
+  pull-requests: write
+```
+
+### Related Files
+
+- `versions.json` - Dependency version configuration
+- `scripts/download_deps.sh` - Downloads PKL dependencies
+- `scripts/fix_deps_imports.sh` - Updates import paths
+- `OFFLINE.md` - Offline dependency documentation
+
+## Release
+
+**File:** `release.yaml`
+
+### Purpose
+Builds and releases schema packages, generates documentation.
+
+### Triggers
+- Push to tags
+- Push to main/master branch
+- Pull requests to main/master
+
+See workflow file for detailed configuration.
+
+## Test PKLDoc
+
+**File:** `test-pkldoc.yaml`
+
+### Purpose
+Tests PKL documentation generation.
+
+See workflow file for detailed configuration.

+## Automated Dependency Updates
+
+### GitHub Actions Workflow
+The repository includes an automated workflow (`.github/workflows/auto-update-dependencies.yml`) that:
+- **Runs Daily**: Checks for new PKL and pkl-go releases every day at 00:00 UTC
+- **Manual Trigger**: Can be triggered manually via GitHub Actions UI
+- **Automatic PRs**: Creates pull requests when updates are available
+
+**What it does:**
+1. Fetches latest versions from GitHub releases
+2. Compares with current versions in `versions.json`
+3. Updates all necessary files:
+   - `versions.json` - Version references
+   - `go.mod` and `go.sum` - Go dependencies

+# Auto-update Workflow Quick Start Guide
+
+## 🎯 What This Does
+
+Automatically keeps your PKL and pkl-go dependencies up-to-date by:
+- Checking for new releases daily
+- Creating PRs when updates are available
+- Running tests to ensure compatibility
+- Providing detailed changelogs
+
+## 🚀 Getting Started
+
+### 1. Verify Workflow is Active
+
+After pushing/merging the workflow:
+
+```bash
+# Check if workflow file exists
+ls -la .github/workflows/auto-update-dependencies.yml
+
+# View workflow in GitHub
+# Go to: https://github.com/kdeps/schema/actions
+```
+
+### 2. Test Locally First (Recommended)
+
+Before the first scheduled run, test the logic locally:
+
+```bash
+# Run the test script
+./scripts/test_workflow_logic.sh
+```
+
+**Current Status (as of test):**
+```
+Updates available:
+  • PKL: 0.29.1 → 0.30.2
+  • pkl-go: 0.11.1 → 0.12.1
+```
+
+### 3. Trigger First Run Manually
+
+Go to GitHub Actions and trigger manually:
+
+1. Visit: https://github.com/kdeps/schema/actions/workflows/auto-update-dependencies.yml
+2. Click "Run workflow" (top right)
+3. Select branch: `main`
+4. Click "Run workflow" button
+
+**Expected:** A PR will be created with title:
+```
+chore: auto-update PKL to 0.30.2 and pkl-go to 0.12.1
+```
+
+### 4. Review the PR
+
+When the PR is created:
+
+✅ **Check PR Details:**
+- Title matches format: `chore: auto-update ...`
+- Labels: `dependencies`, `autoupdate`
+- Body contains changelog
+- All files listed are relevant
+
+✅ **Review Changed Files:**
+- `versions.json` - versions updated correctly
+- `go.mod` - pkl-go version updated
+- `go.sum` - checksums updated
+- `build.gradle.kts` - PKL plugin version updated
+- `.pkl` files - minPklVersion updated
+- Dependencies downloaded to `deps/pkl/external/`
+- Assets copied to `assets/pkl/external/`
+
+✅ **Verify Tests Pass:**
+- All GitHub Actions checks pass
+- Go tests successful
+- No errors in workflow logs
+
+### 5. Test PR Locally (Optional but Recommended)
+
+```bash
+# Checkout the PR
+gh pr checkout <PR_NUMBER>
+
+# Or manually
+git fetch origin pull/<PR_NUMBER>/head:auto-update-test
+git checkout auto-update-test
+
+# Run tests
+cd assets && go test -v ./...
+
+# Test PKL evaluation
+pkl eval deps/pkl/Tool.pkl --no-cache --format json
+
+# Build
+make generate
+```
+
+### 6. Merge the PR
+
+Once verified:
+1. Approve the PR
+2. Merge to main
+3. PR branch auto-deletes
+
+### 7. Verify Automated Runs
+
+The workflow will now run daily at 00:00 UTC.
+
+**Monitor:**
+- Check Actions tab: https://github.com/kdeps/schema/actions
+- View workflow history
+- Check for any failures
+
+## 📅 Schedule
+
+**Automatic Runs:**
+- Daily at 00:00 UTC (midnight)
+- Only creates PR if updates available
+
+**Manual Runs:**
+- Anytime via GitHub Actions UI
+- Useful for immediate updates
+
+## 🔧 Maintenance
+
+### Monthly Tasks
+
+```bash
+# Check workflow status
+gh workflow view auto-update-dependencies.yml
+
+# List recent runs
+gh run list --workflow=auto-update-dependencies.yml --limit 10
+
+# Check for failed runs
+gh run list --workflow=auto-update-dependencies.yml --status=failure
+```
+
+### When Updates Fail
+
+1. **Check workflow logs:**
+   ```bash
+   gh run view <RUN_ID> --log
+   ```
+
+2. **Common issues:**
+   - API rate limits → Wait and retry
+   - Test failures → Review breaking changes
+   - Network issues → Transient, retry later
+
+3. **Manual fallback:**
+   ```bash
+   # Update manually if needed
+   ./scripts/update_versions.sh
+   ./scripts/update_all.sh
+   ```
+
+## 📊 Monitoring Dashboard
+
+Track these on the Actions page:
+
+- ✅ Success rate (should be >95%)
+- ⏱️ Run duration (typical: 5-10 minutes)
+- 📈 Update frequency (depends on upstream releases)
+- 🔄 PRs created vs merged
+
+## 🎓 Learning from PRs
+
+Each auto-generated PR is a learning opportunity:
+
+**What to review:**
+1. **Release Notes** - Linked in PR body
+2. **Breaking Changes** - Check before merging
+3. **New Features** - PKL/pkl-go improvements
+4. **Bug Fixes** - Fixes that benefit you
+
+## 🆘 Troubleshooting
+
+### Workflow Not Running
+
+```bash
+# Check cron schedule in workflow file
+grep cron .github/workflows/auto-update-dependencies.yml
+
+# Verify workflow is enabled
+gh workflow list | grep auto-update
+```
+
+### No PR Created Despite Updates
+
+Check workflow run logs:
+```bash
+gh run list --workflow=auto-update-dependencies.yml --limit 1
+gh run view <RUN_ID> --log
+```
+
+Possible causes:
+- No updates available
+- Tests failed
+- Permission issues
+
+### Multiple PRs Created
+
+If multiple PRs for same update:
+1. Close duplicates
+2. Keep newest PR
+3. Consider adding existing PR check
+
+### Tests Failing
+
+Review the specific test failures:
+1. Check PR for test logs
+2. Review release notes for breaking changes
+3. May need code updates to handle new version
+
+## 🎯 Success Metrics
+
+Your workflow is working well when:
+
+- ✅ Runs complete without errors
+- ✅ PRs are created within hours of upstream releases
+- ✅ Tests pass consistently
+- ✅ Updates merge smoothly
+- ✅ No manual intervention needed
+
+## 🔗 Useful Links
+
+- **Workflow File:** `.github/workflows/auto-update-dependencies.yml`
+- **Documentation:** `.github/workflows/README.md`

+
+### Troubleshooting Guide
+
+#### Workflow Fails at Checkout
+**Cause:** Permission issues
+**Fix:** Verify repository permissions, check GITHUB_TOKEN
+
+#### Workflow Fails at Version Fetch
+**Cause:** GitHub API rate limiting or network issues
+**Fix:** Wait and retry, check GitHub API status
+
+#### Workflow Fails at Dependency Download
+**Cause:** Network issues, wrong versions, missing dependencies
+**Fix:**
+- Check `versions.json` format
+- Verify network connectivity
+- Check if versions exist in upstream repos
+
+#### Tests Fail After Update
+**Cause:** Breaking changes in new version
+**Fix:**
+- Review release notes for breaking changes
+- May need manual fixes to code
+- Consider pinning to previous version temporarily
+
+#### PR Not Created
+**Cause:** No changes detected, permission issues
+**Fix:**
+- Check if versions actually changed
+- Verify `contents: write` and `pull-requests: write` permissions
+- Check workflow logs for errors
+
+#### Multiple PRs Created
+**Cause:** Workflow ran multiple times before first PR merged
+**Fix:**
+- Close duplicate PRs
+- Merge the appropriate one
+- May want to add check for existing PRs
+
+### Performance Monitoring
+
+Track these metrics:
+- [ ] Workflow execution time (typical: 5-10 minutes)
+- [ ] Frequency of updates (varies by upstream release cadence)
+- [ ] Test success rate
+- [ ] Time from PR creation to merge
+
+### Security Considerations
+
+- [ ] PRs are reviewed before merging
+- [ ] Dependency sources are trusted (apple/pkl, apple/pkl-go)
+- [ ] Tests catch potential issues
+- [ ] No secrets exposed in workflow logs
+
+### Maintenance
+
+Monthly checks:
+- [ ] Workflow still running on schedule
+- [ ] No failed runs requiring attention
+- [ ] Dependencies are up-to-date
+- [ ] Documentation is current
+
+Quarterly review:
+- [ ] Update GitHub Actions versions if needed
+- [ ] Review and update Go/Java versions
+- [ ] Optimize workflow if needed
+- [ ] Check for GitHub Actions best practice updates
+
+## Quick Test Commands
+
+```bash
+# Check workflow syntax
+yamllint .github/workflows/auto-update-dependencies.yml
+
+# View current versions
+jq '.' versions.json
+
+# Check for latest pkl version
+curl -s https://api.github.com/repos/apple/pkl/releases/latest | jq -r '.tag_name'
+
+# Check for latest pkl-go version
+curl -s https://api.github.com/repos/apple/pkl-go/releases/latest | jq -r '.tag_name'
+
+# Test scripts locally
+./scripts/update_versions.sh
+./scripts/download_deps.sh
+./scripts/fix_deps_imports.sh
+
+# Verify offline functionality
+pkl eval deps/pkl/Tool.pkl --no-cache
+
+# Run Go tests
+cd assets && go test -v ./...
+```
+
+## Success Criteria

+# Auto-update Workflow Quick Start Guide
+
+## 🎯 What This Does
+
+Automatically keeps your PKL and pkl-go dependencies up-to-date by:
+- Checking for new releases daily
+- Creating PRs when updates are available
+- Running tests to ensure compatibility
+- Providing detailed changelogs
+
+## 🚀 Getting Started
+
+### 1. Verify Workflow is Active
+
+After pushing/merging the workflow:
+
+```bash
+# Check if workflow file exists
+ls -la .github/workflows/auto-update-dependencies.yml
+
+# View workflow in GitHub
+# Go to: https://github.com/kdeps/schema/actions
+```
+
+### 2. Test Locally First (Recommended)
+
+Before the first scheduled run, test the logic locally:
+
+```bash
+# Run the test script
+./scripts/test_workflow_logic.sh
+```
+
+**Current Status (as of test):**
+```
+Updates available:
+  • PKL: 0.29.1 → 0.30.2
+  • pkl-go: 0.11.1 → 0.12.1
+```
+
+### 3. Trigger First Run Manually
+
+Go to GitHub Actions and trigger manually:
+
+1. Visit: https://github.com/kdeps/schema/actions/workflows/auto-update-dependencies.yml
+2. Click "Run workflow" (top right)
+3. Select branch: `main`
+4. Click "Run workflow" button
+
+**Expected:** A PR will be created with title:
+```
+chore: auto-update PKL to 0.30.2 and pkl-go to 0.12.1
+```
+
+### 4. Review the PR
+
+When the PR is created:
+
+✅ **Check PR Details:**
+- Title matches format: `chore: auto-update ...`
+- Labels: `dependencies`, `autoupdate`
+- Body contains changelog
+- All files listed are relevant
+
+✅ **Review Changed Files:**
+- `versions.json` - versions updated correctly
+- `go.mod` - pkl-go version updated
+- `go.sum` - checksums updated
+- `build.gradle.kts` - PKL plugin version updated
+- `.pkl` files - minPklVersion updated
+- Dependencies downloaded to `deps/pkl/external/`
+- Assets copied to `assets/pkl/external/`
+
+✅ **Verify Tests Pass:**
+- All GitHub Actions checks pass
+- Go tests successful
+- No errors in workflow logs
+
+### 5. Test PR Locally (Optional but Recommended)
+
+```bash
+# Checkout the PR
+gh pr checkout <PR_NUMBER>
+
+# Or manually
+git fetch origin pull/<PR_NUMBER>/head:auto-update-test
+git checkout auto-update-test
+
+# Run tests
+cd assets && go test -v ./...
+
+# Test PKL evaluation
+pkl eval deps/pkl/Tool.pkl --no-cache --format json
+
+# Build
+make generate
+```
+
+### 6. Merge the PR
+
+Once verified:
+1. Approve the PR
+2. Merge to main
+3. PR branch auto-deletes
+
+### 7. Verify Automated Runs
+
+The workflow will now run daily at 00:00 UTC.
+
+**Monitor:**
+- Check Actions tab: https://github.com/kdeps/schema/actions
+- View workflow history
+- Check for any failures
+
+## 📅 Schedule
+
+**Automatic Runs:**
+- Daily at 00:00 UTC (midnight)
+- Only creates PR if updates available
+
+**Manual Runs:**
+- Anytime via GitHub Actions UI
+- Useful for immediate updates
+
+## 🔧 Maintenance
+
+### Monthly Tasks
+
+```bash
+# Check workflow status
+gh workflow view auto-update-dependencies.yml
+
+# List recent runs
+gh run list --workflow=auto-update-dependencies.yml --limit 10
+
+# Check for failed runs
+gh run list --workflow=auto-update-dependencies.yml --status=failure
+```
+
+### When Updates Fail
+
+1. **Check workflow logs:**
+   ```bash
+   gh run view <RUN_ID> --log
+   ```
+
+2. **Common issues:**
+   - API rate limits → Wait and retry
+   - Test failures → Review breaking changes
+   - Network issues → Transient, retry later
+
+3. **Manual fallback:**
+   ```bash
+   # Update manually if needed
+   ./scripts/update_versions.sh
+   ./scripts/update_all.sh
+   ```
+
+## 📊 Monitoring Dashboard
+
+Track these on the Actions page:
+
+- ✅ Success rate (should be >95%)
+- ⏱️ Run duration (typical: 5-10 minutes)
+- 📈 Update frequency (depends on upstream releases)
+- 🔄 PRs created vs merged
+
+## 🎓 Learning from PRs
+
+Each auto-generated PR is a learning opportunity:
+
+**What to review:**
+1. **Release Notes** - Linked in PR body
+2. **Breaking Changes** - Check before merging
+3. **New Features** - PKL/pkl-go improvements
+4. **Bug Fixes** - Fixes that benefit you
+
+## 🆘 Troubleshooting
+
+### Workflow Not Running
+
+```bash
+# Check cron schedule in workflow file
+grep cron .github/workflows/auto-update-dependencies.yml
+
+# Verify workflow is enabled
+gh workflow list | grep auto-update
+```
+
+### No PR Created Despite Updates
+
+Check workflow run logs:
+```bash
+gh run list --workflow=auto-update-dependencies.yml --limit 1
+gh run view <RUN_ID> --log
+```
+
+Possible causes:
+- No updates available
+- Tests failed
+- Permission issues
+
+### Multiple PRs Created
+
+If multiple PRs for same update:
+1. Close duplicates
+2. Keep newest PR
+3. Consider adding existing PR check
+
+### Tests Failing
+
+Review the specific test failures:
+1. Check PR for test logs
+2. Review release notes for breaking changes
+3. May need code updates to handle new version
+
+## 🎯 Success Metrics
+
+Your workflow is working well when:
+
+- ✅ Runs complete without errors
+- ✅ PRs are created within hours of upstream releases
+- ✅ Tests pass consistently
+- ✅ Updates merge smoothly
+- ✅ No manual intervention needed
+
+## 🔗 Useful Links
+
+- **Workflow File:** `.github/workflows/auto-update-dependencies.yml`
+- **Documentation:** `.github/workflows/README.md`

+
+### Troubleshooting Guide
+
+#### Workflow Fails at Checkout
+**Cause:** Permission issues
+**Fix:** Verify repository permissions, check GITHUB_TOKEN
+
+#### Workflow Fails at Version Fetch
+**Cause:** GitHub API rate limiting or network issues
+**Fix:** Wait and retry, check GitHub API status
+
+#### Workflow Fails at Dependency Download
+**Cause:** Network issues, wrong versions, missing dependencies
+**Fix:**
+- Check `versions.json` format
+- Verify network connectivity
+- Check if versions exist in upstream repos
+
+#### Tests Fail After Update
+**Cause:** Breaking changes in new version
+**Fix:**
+- Review release notes for breaking changes
+- May need manual fixes to code
+- Consider pinning to previous version temporarily
+
+#### PR Not Created
+**Cause:** No changes detected, permission issues
+**Fix:**
+- Check if versions actually changed
+- Verify `contents: write` and `pull-requests: write` permissions
+- Check workflow logs for errors
+
+#### Multiple PRs Created
+**Cause:** Workflow ran multiple times before first PR merged
+**Fix:**
+- Close duplicate PRs
+- Merge the appropriate one
+- May want to add check for existing PRs
+
+### Performance Monitoring
+
+Track these metrics:
+- [ ] Workflow execution time (typical: 5-10 minutes)
+- [ ] Frequency of updates (varies by upstream release cadence)
+- [ ] Test success rate
+- [ ] Time from PR creation to merge
+
+### Security Considerations
+
+- [ ] PRs are reviewed before merging
+- [ ] Dependency sources are trusted (apple/pkl, apple/pkl-go)
+- [ ] Tests catch potential issues
+- [ ] No secrets exposed in workflow logs
+
+### Maintenance
+
+Monthly checks:
+- [ ] Workflow still running on schedule
+- [ ] No failed runs requiring attention
+- [ ] Dependencies are up-to-date
+- [ ] Documentation is current
+
+Quarterly review:
+- [ ] Update GitHub Actions versions if needed
+- [ ] Review and update Go/Java versions
+- [ ] Optimize workflow if needed
+- [ ] Check for GitHub Actions best practice updates
+
+## Quick Test Commands
+
+```bash
+# Check workflow syntax
+yamllint .github/workflows/auto-update-dependencies.yml
+
+# View current versions
+jq '.' versions.json
+
+# Check for latest pkl version
+curl -s https://api.github.com/repos/apple/pkl/releases/latest | jq -r '.tag_name'
+
+# Check for latest pkl-go version
+curl -s https://api.github.com/repos/apple/pkl-go/releases/latest | jq -r '.tag_name'
+
+# Test scripts locally

+   ```
+
+2. **Revert Changes:**
+   ```bash
+   git revert <commit-hash>
+   git push origin main
+   ```
+
+3. **Manual Updates:**
+   - Use existing scripts manually
+   - Follow OFFLINE.md documentation
+   - Fix issues before re-enabling workflow
+
+4. **Fix and Re-enable:**
+   - Address root cause

Subject: [PATCH 04/13] fix: correct asset copying logic in workflow

- Fix 'deps/pkl/external' not found error
- download_deps.sh creates assets/pkl/external directly
- Only need to copy PKL files from deps/pkl to assets/pkl
- External dependencies already in correct location
- Add better error messaging and validation

Subject: [PATCH 07/13] feat: generic case-insensitive conflict resolution with
 auto-fixing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Automatic detection of ALL case-insensitive filename conflicts
- Works for pkl-go, pkl-pantry, and any future dependencies
- Automatically renames conflicting files with parent dir prefix
- Fixes all import/reference statements to renamed files
- Cross-platform (macOS/Linux sed compatibility)
- Bash 3.2+ compatible (macOS default bash)

How it works:
1. detect_conflicts() - Scans all .pkl files, finds conflicts
2. apply_renames() - Renames conflicting files automatically
3. fix_references() - Updates all imports to use new names

Example: Config.pkl vs configuration.pkl
→ Renames to: Config.pkl and com.circleci.v2_configuration.pkl
→ Updates all files that import configuration.pkl

Subject: [PATCH 08/13] perf: optimize reference fixing in download_deps.sh
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Dramatically improve performance of fix_references() function:

- Build sed script once instead of per-file execution
- Pre-filter files using grep -l to only process files with matches
- Single sed pass per file instead of nested loops
- Reduce complexity from O(n×m) to O(n×grep + k×sed)

This addresses the "updating references takes a lot of time" issue
by avoiding unnecessary processing of files that don't reference
renamed dependencies.

Subject: [PATCH 09/13] fix: simplify error handling in fix_references
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove hardcoded error checks and counter arithmetic that could
cause exit code 1 with set -e. Simplify to: build → filter → apply → cleanup.

- Remove count variable and arithmetic expansion
- Use xargs on Linux for better performance
- Explicit return 0 for success
- Let bash handle errors naturally

Subject: [PATCH 10/13] refactor: atomic conflict resolution - detect, rename,
 fix immediately
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Refactor conflict resolution to handle each conflict atomically:
- Upon detection: rename file immediately
- Fix references for that file immediately
- Then move to next conflict

Benefits:
- Simpler flow (single function instead of 3)
- Easier to debug (know exactly which file causes issues)
- No intermediate state files needed
- Cleaner code

Removed:
- detect_conflicts()
- apply_renames()
- fix_references()

Added:
- detect_and_resolve_conflicts() - handles everything atomically
- fix_references_for_file() - fixes refs for single file

Subject: [PATCH 11/13] feat: add final global reference check after conflict
 resolution
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After all atomic conflict resolutions, run a final global sweep to
catch any references that might have been missed.

Flow:
1. Detect conflict → rename → fix references (atomic)
2. Track all renames in /tmp/all_renames.txt
3. After all conflicts: global check for remaining refs
4. Fix any missed references
5. Clean up

This provides belt-and-suspenders safety - atomic fixes plus
a final safety net.

Subject: [PATCH 12/13] fix: preserve directory structure when updating
 references
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Change reference fixing to only replace the basename, not the entire
path. This preserves relative import structures.

Before:
  import "../foo/config.pkl"
  → import "pkl-pantry/.../com.circleci.v2_config.pkl" ❌ (breaks)

After:
  import "../foo/config.pkl"
  → import "../foo/com.circleci.v2_config.pkl" ✅ (correct)

Changes:
- Only replace the filename part: /config.pkl → /new_name.pkl
- Preserve directory structure from original imports
- Apply to both atomic fixes and final global check

Subject: [PATCH 13/13] fix: prevent renamed files from creating new conflicts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Critical fixes:
1. Record NEW filename's lowercase, not old (was the bug!)
2. Check if generated name will conflict before renaming
3. Add numeric suffix (_2, _3, etc.) if new name conflicts

Before:
  Config.pkl → com.circleci.v2_Config.pkl (lowercase: ...config.pkl)
  config.pkl → com.circleci.v2_config.pkl (lowercase: ...config.pkl)
  Result: STILL CONFLICTS! ❌

After:
  Config.pkl → com.circleci.v2_Config.pkl (records: ...config.pkl)
  config.pkl → com.circleci.v2_config_2.pkl (detects conflict, adds _2)
  Result: No conflicts ✅
