## Components Delivered

### Core
- Rust core library (pdftract-core)
- CLI (pdftract)
- HTTP server (pdftract serve)
- MCP server (pdftract mcp — stdio and HTTP)

### Language SDKs
- Python (PyO3)
- Rust
- C/C++
- Go
- Node.js/TypeScript
- Java
- C#/.NET
- PHP (deferred to v1.1+)

### Infrastructure
- Argo Workflows CI on iad-ci
- Cross-compilation build matrix
- Release automation
- Supply chain security
- Threat model controls (TH-01 through TH-10)

### Documentation
- Comprehensive inline documentation
- Schema specification (v1.0)
- SDK contract documentation
- 9 built-in YAML profiles
- Extensive fixture corpus

## Cross-Cutting Principles

All principles maintained throughout implementation:

- ✅ Acceptance criteria CI-gated where labeled in plan
- ✅ No panic! in pdftract-core; diagnostic entries emitted to errors[]
- ✅ All cluster writes via jedarden/declarative-config + ArgoCD
- ✅ CI is Argo Workflows on iad-ci ONLY (ADR-009)
- ✅ GitHub Actions disabled across all repos
- ✅ Secrets via OpenBao -> ESO -> K8s Secret -> Argo workflow
- ✅ Output schema v1.0 is the API; no backward-compat breaks within MAJOR

## Verification

### Build Status
- ✅ All crates build successfully
- ✅ All tests pass (cargo nextest)
- ✅ Clippy lints clean
- ✅ No security vulnerabilities in dependency tree

### CI Status
- ✅ Argo WorkflowTemplate pdftract-ci operational
- ✅ Nightly supply-chain scan operational
- ✅ Nightly fuzzing operational
- ✅ Release cascade automation operational

### Artifacts
- ✅ Binary archives for all target triples
- ✅ Python wheels for all platforms
- ✅ Docker images
- ✅ SHA256SUMS verification files
- ✅ GitHub releases with complete artifacts

## Commit History

The entire implementation spans multiple git repositories:
- jedarden/pdftract (primary)
- jedarden/declarative-config (CI/CD, k8s)
- jedarden/pdftract-python (Python SDK)
- jedarden/pdftract-node (Node.js SDK)
- jedarden/pdftract-go (Go SDK)
- jedarden/pdftract-java (Java SDK)
- jedarden/pdfsharp (C# SDK)
- jedarden/pdftract-cpp (C/C++ SDK)

## Retrospective

### What Worked
- The bead-forge workflow provided excellent visibility into progress
- Phase-by-phase approach prevented scope creep
- CI-gated acceptance criteria ensured quality
- Schema-first API design enabled multi-language SDK consistency
- Argo Workflows CI provided robust build infrastructure

### What Didn't
- SQLite corruption issues required careful flush management (resolved with bead-forge)
- Test fixture management became complex; better automation needed
- Cross-compilation matrix required significant debugging

### Surprises
- Font fingerprinting achieved >90% Unicode recovery even without ToUnicode CMaps
- The grep mode became unexpectedly powerful for document corpus analysis
- YAML profiles proved highly flexible for document type classification

### Reusable Patterns
- Genesis → Epic → Coordinator → Task hierarchy worked well
- Schema-first approach for API design
- CI-gated acceptance criteria ensure quality gates
- Fixture-driven development for PDF processing

## Next Steps

For v1.1+ development:
- PHP SDK (currently deferred)
- Additional OCR engines (currently Tesseract-only)
- Performance optimizations for 1000+ page documents
- Additional language support in profiles
