Components Delivered

Core

  • Java
  • C#/.NET
  • PHP (deferred to v1.1+)

Infrastructure

  • Argo Workflows CI on iad-ci

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
