## ⚠️ Current Status

### Build Status: ⚠️ Blocked

The CI/CD pipeline is **fully configured** but currently **blocked by Rust compilation errors**.

**Issues Found:**
1. ❌ Unresolved import: `JJOperationInternal` in `src/hooks.rs`
2. ❌ Type mismatches: `u32` vs `u64` for timeout and duration
3. ❌ N-API trait bounds: `u64` and `JJDiff` don't implement required traits
4. ❌ Error type conversions: Custom errors need `napi::Error` conversion

### Required Fixes

**Priority 1 - Critical Errors:**

**File:** `src/hooks.rs` (Line 7)
```rust
// Fix import path:
use crate::operations::JJOperationInternal;
```

**File:** `src/wrapper.rs` (Line 100)
```rust
// Fix type conversion:
let timeout = std::time::Duration::from_millis(self.config.timeout_ms as u64);
```

**File:** `src/operations.rs` (Line 280)
```rust
// N-API doesn't support u64, use f64:
#[napi(object)]
pub struct JJOperationMetrics {
    pub duration_ms: f64,  // Changed from u64
}
```

**File:** `src/types.rs`
```rust
// Add N-API attribute to JJDiff:
#[napi(object)]
pub struct JJDiff {
    // ... existing fields
}
```

**Priority 2 - Error Handling:**

**All async functions returning custom Result:**
```rust
// Add error conversion:
pub async fn operation(&self) -> napi::Result<T> {
    self.inner_operation()
        .await
        .map_err(|e| napi::Error::from_reason(e.to_string()))
}
```

## 🚀 How to Use After Fixes

### Local Testing
```bash
# After fixing Rust errors:
npm run build
npm run test:basic

# Verify artifact:
ls -lh *.node
node -e "const jj = require('./index.js'); console.log('✅ Loaded')"
```

### Trigger CI/CD
```bash
# Push to main:
git add .
git commit -m "fix: Resolve N-API compilation errors"
git push origin main

# Monitor build:
gh run watch
```

### Release Process
```bash
# After successful builds:
npm version minor  # or patch/major
git push --follow-tags

# Create GitHub release:
gh release create v1.1.0 \
  --title "Release v1.1.0" \
  --notes "Bug fixes and improvements"

# CI automatically:
# 1. Builds all 9 platforms
# 2. Publishes to npm
# 3. Creates GitHub release assets
```

## 📋 Checklist for Next Steps

### Immediate Actions
- [ ] Fix Rust compilation errors (see "Required Fixes" above)
- [ ] Test local build: `npm run build`
- [ ] Verify N-API bindings: `npm run test:basic`
- [ ] Commit fixes and push to trigger CI

### Before First Release
- [ ] Verify all 9 platforms build successfully
- [ ] Test artifacts on target platforms
- [ ] Set up `NPM_TOKEN` secret: `gh secret set NPM_TOKEN`
- [ ] Configure branch protection rules
- [ ] Review and update `optionalDependencies` versions

### Post-Release
- [ ] Verify npm publication: `npm view agentic-jujutsu`
- [ ] Test installation: `npx agentic-jujutsu@latest --version`
- [ ] Download and verify GitHub release assets
- [ ] Monitor download statistics

## 🔒 Security Setup

### Required GitHub Secrets
```bash
# Set NPM token for publishing:
gh secret set NPM_TOKEN
# Paste your npm Automation token

# Verify:
gh secret list
```

### Generate NPM Token
1. Visit: https://www.npmjs.com/settings/YOUR_USERNAME/tokens
2. Click "Generate New Token" → "Automation"
3. Copy token and add to GitHub secrets

### Branch Protection
```bash
# Recommended settings:
- Require pull request reviews
- Require status checks (CI must pass)
- No force pushes to main
- Require signed commits (optional)
```

## 🆘 Support

### If Build Fails
1. Check GitHub Actions logs
2. Review error messages in workflow runs
3. Test locally: `npm run build`
4. Check [docs/NAPI_CI_CD_COMPLETE.md](./NAPI_CI_CD_COMPLETE.md) troubleshooting section

### If Publishing Fails
1. Verify NPM_TOKEN secret is set
2. Check npm token permissions (must be "Automation")
3. Verify package.json `publishConfig.access: "public"`
4. Test locally: `npm publish --dry-run`
