|
|
|
|
## 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
|
|
|

## 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
|
