+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+This repository builds AWS Lambda layers containing Tesseract OCR libraries and the tesseract command-line binary. It supports Amazon Linux 2023 (recommended) and Amazon Linux 2 (deprecated) runtimes, with ready-to-use binaries and Docker-based build processes.
+
+## Key Architecture
+
+### Projen-based Repository Management
+
+- All repository configuration is managed through `.projenrc.ts`
+- Run `npx projen` to regenerate configuration files after editing `.projenrc.ts`
+- The project uses projen to manage nested subprojects (example/cdk, continous-integration/lambda-handlers/node)
+
+### Docker Build System
+
+Two Dockerfiles build the Tesseract layer for different Amazon Linux versions:
+- `Dockerfile.al2023` - Amazon Linux 2023 (**recommended** - Python 3.12+, Node.js 20+, Ruby 3.2+, Java 17+)
+- `Dockerfile.al2` - Amazon Linux 2 (**deprecated** - Python 3.8-3.11, Node.js 18, Ruby 2.7, Java 8/11)
+
+Amazon Linux 1 support has been removed.
+
+The Dockerfiles compile Tesseract OCR and Leptonica from source with configurable build arguments:
+- `TESSERACT_VERSION` - tesseract version to build
+- `LEPTONICA_VERSION` - leptonica version to build
+- `OCR_LANG` - additional language data to include (beyond eng/osd)
+- `TESSERACT_DATA_SUFFIX` - traineddata variant: empty (default), `_best`, or `_fast`
+- `TESSERACT_DATA_VERSION` - version of trained models (currently 4.1.0)
+
+### Integration Testing & Bundling
+
+Located in `continous-integration/`:
+- `main.ts` - CDK app that builds layers using Docker bundling and creates test Lambda functions
+- `lambda-handlers/python/` - Python handler for testing
+- `lambda-handlers/node/` - Node.js handler for testing
+
+The CI/CD flow:
+1. `npx cdk synth` synthesizes the stack and bundles layer artifacts via Docker
+2. AWS SAM CLI locally invokes test functions with the built layer
+3. Test output is checked for errors
+4. Successful builds copy artifacts to `ready-to-use/amazonlinux-2023/` and `ready-to-use/amazonlinux-2/`
+
+### Ready-to-use Artifacts
+
+The `ready-to-use/` directory contains pre-built layer binaries:
+- `amazonlinux-2023/` - **Recommended** layer contents for AL2023-based runtimes
+- `amazonlinux-2/` - **Deprecated** layer contents for AL2-based runtimes (will be removed)
+- These are deployed to `/opt` when attached to a Lambda function
+
+## Essential Commands
+
+### Building & Testing
+
+```bash
+# Install dependencies (runs across all subprojects)
+npm ci
+
+# Build the project (compile TypeScript)
+npm run build
+
+# Run unit tests
+npm test
+
+# Synthesize CDK stack (triggers Docker build of layer)
+npm run synth
+
+# Run integration tests (requires Docker and SAM CLI, AL2023 only)
+npm run test:integration          # All AL2023 tests
+npm run test:integration:al2023   # AL2023 tests (Python 3.12 + Node.js 20)
+npm run test:integration:python312 # Python 3.12 (AL2023) test
+npm run test:integration:node20   # Node.js 20 (AL2023) test
+
+# Bundle ready-to-use artifacts after synth
+npm run bundle:binary
+
+# Create release assets (zip files)
+npm run package
+```
+
+### Linting
+
+```bash
+npm run eslint
+```
+
+### Building Custom Layers
+
+```bash
+# Build AL2023 layer (recommended)
+docker build --build-arg TESSERACT_VERSION=5.5.2 \
+  --build-arg OCR_LANG=fra \
+  -t tesseract-lambda-layer \
+  -f Dockerfile.al2023 .
+
+# Build AL2 layer (deprecated)
+docker build -t tesseract-lambda-layer -f Dockerfile.al2 .
+
+# Extract built artifacts from container
+export CONTAINER=$(docker run -d tesseract-lambda-layer false)
+docker cp $CONTAINER:/opt/build-dist layer
+docker rm $CONTAINER
+unset CONTAINER
+```
+
+### Upgrading Dependencies
+
+```bash
+# Upgrade all dependencies (JavaScript)
+npm run upgrade
+
+# Upgrade Python dependencies in CI handlers
+npm run upgrade:ci:py
+
+# Upgrade all subprojects
+npm run upgrade:subprojects
+```
+
+## CDK Usage Patterns
+
+This repository uses CDK's Docker bundling feature extensively:
+
+```typescript
+// Building a layer from Docker
+const layer = new lambda.LayerVersion(stack, 'layer', {
+  code: Code.fromAsset(pathToSource, {
+    bundling: {
+      image: DockerImage.fromBuild(path, { file: 'Dockerfile.al2' }),
+      command: ['/bin/bash', '-c', 'cp -r /opt/build-dist/. /asset-output/'],
+    },
+  }),
+});
+```
+
+The bundling happens during `cdk synth`, not during `cdk deploy`. Artifacts are cached in `cdk.out/`.
+
+## Example Projects
+
+Two example projects demonstrate layer usage:
+
+### Serverless Framework (`example/serverless/`)
+- References `ready-to-use/amazonlinux-2/` via `layers.path` in `serverless.yml`
+- Uses serverless-python-requirements plugin with Docker
+
+### AWS CDK (`example/cdk/`)
+- Creates LayerVersion from `ready-to-use/amazonlinux-2/` using `Code.fromAsset()`
+- Separate projen subproject with its own dependencies
+
+## Important Notes
+
+- Library files are stripped during build (using `strip -s`) to reduce size
+- Stripping can cause issues if build runtime differs from Lambda runtime - use matching base images
+- The layer includes tesseract binaries in `/opt/bin` and libraries in `/opt/lib`
+- Ready-to-use artifacts are tracked in git for convenience (large binary files)
+- Release workflow is scheduled annually (Jan 1) via projen `releaseTrigger`
+- Dependency upgrades run weekly via GitHub Actions with projen credentials from GitHub App

+# Migration from AL2 to AL2023
+
+## Why Migrate?
+
+- **Extended Support**: AL2023 receives updates until 2028
+- **Modern Runtimes**: Python 3.12+, Node.js 20+
+- **Performance**: Improved compiler optimizations and newer system libraries
+- **Security**: Latest security patches and cryptographic libraries
+
+## Migration Steps
+
+### 1. Update Runtime
+
+| Current Runtime | → | AL2023 Runtime |
+|-----------------|---|----------------|
+| Python 3.8-3.11 | → | Python 3.12    |
+| Node.js 18      | → | Node.js 20     |
+| Ruby 2.7        | → | Ruby 3.2       |
+
+### 2. Update Layer Reference
+
+**Serverless Framework**:
+```yaml
+# Before
+layers:
+  tesseractAl2:
+    path: ready-to-use/amazonlinux-2
+    compatibleRuntimes:
+      - python3.8
+
+# After
+layers:
+  tesseractAl2023:
+    path: ready-to-use/amazonlinux-2023
+    compatibleRuntimes:
+      - python3.12
+```
+
+**AWS CDK**:
+```typescript
+// Before
+const layer = new lambda.LayerVersion(stack, 'layer', {
+  code: Code.fromAsset('ready-to-use/amazonlinux-2'),
+});
+new lambda.Function(stack, 'fn', {
+  runtime: Runtime.PYTHON_3_8,
+  layers: [layer],
+});
+
+// After
+const layer = new lambda.LayerVersion(stack, 'layer', {
+  code: Code.fromAsset('ready-to-use/amazonlinux-2023'),
+});
+new lambda.Function(stack, 'fn', {
+  runtime: Runtime.PYTHON_3_12,
+  layers: [layer],
+});
+```
+
+### 3. Test Locally
+
+```bash
+# Update dependencies for new runtime
+pip install --upgrade -r requirements.txt  # Python
+npm update                                  # Node.js
+
+# Test with SAM CLI
+sam local invoke --runtime python3.12 ...
+```
+
+### 4. Deploy & Monitor
+
+- Deploy to dev/staging environment first
+- Check CloudWatch logs for compatibility issues
+- Verify OCR functionality works correctly
+- Roll out to production gradually
+
+## Common Issues
+
+**Python 3.12 Compatibility**
+- Some packages need updates for Python 3.12
+- Use `pip install --upgrade` for dependencies
+- Check for deprecated Python APIs
+
+**Node.js Native Modules**
+- Native modules must be recompiled for AL2023
+- Ensure node-gyp is up to date
+- Test with `sam local invoke`
+
+**Library Versions**
+- AL2023 may have different .so library versions
+- Error: "cannot open shared object file"
+- Solution: Use the AL2023 layer (not AL2 layer)

+## Action Required
+
+Migrate to Amazon Linux 2023 (AL2023) within the next 6 months.
+
+## Migration Guide
+
+See the [Migration Guide](../../README.md#migration-from-al2-to-al2023) in the main README.
+
+## Timeline
+
+- **Current**: AL2023 fully supported; AL2 binaries available for local builds only
+- **In 6 months**: AL2 removed, AL2023 only
