Phase 0: CI Infrastructure — Verification Note

Bead ID: pdftract-4nj7y Epic: Phase 0: CI Infrastructure (Argo Workflows on iad-ci) Completed: 2026-05-23

Summary

Phase 0 established the complete Argo Workflows CI pipeline required by all subsequent phases. Per ADR-009, all CI runs on the iad-ci Rackspace Spot cluster — GitHub Actions are explicitly forbidden.

Sub-phases Completed

All 10 sub-phase coordinators are CLOSED:

Sub-phase	Bead ID	Description	Status
0.1	pdftract-1wqec	pdftract-ci WorkflowTemplate scaffolding	✅ CLOSED
0.2	pdftract-1bn	Cross-compilation build matrix for 5 target triples	✅ CLOSED
0.3	pdftract-30n	Test execution on musl + glibc	✅ CLOSED
0.4	pdftract-2rf	Static analysis and quality gates (clippy, audit, deny, MSRV, bloat)	✅ CLOSED
0.5	pdftract-33v	Property tests and nightly fuzz job	✅ CLOSED
0.6	pdftract-2t9	Regression corpus runner (Tier 3, 500 PDFs)	✅ CLOSED
0.7	pdftract-60h	Competitive benchmarks (Tier 4, hyperfine)	✅ CLOSED
0.8	pdftract-23k1	pdftract-py-ci WorkflowTemplate stub	✅ CLOSED
0.9	pdftract-4b0z	Release publishing (GitHub Releases on milestone tags)	✅ CLOSED
0.10	pdftract-3i1o	CI observability — green-run smoke test and status reporting	✅ CLOSED

Acceptance Criteria Verification

✅ pdftract-ci active in iad-ci

• The pdftract-ci WorkflowTemplate is deployed in the iad-ci cluster
• Runs on every PR to jedarden/pdftract via Argo Workflows

✅ All 10 sub-phase coordinators closed

• Verified via bf show for each sub-phase bead
• All show Status: closed

✅ Green CI run demonstrates required capabilities

The CI pipeline now includes:

• Build: Cross-compilation for 5 target triples (x86_64-unknown-linux-{musl,gnu}, aarch64-unknown-linux-{musl,gnu}, x86_64-apple-darwin)
• Test: cargo test on both musl and glibc
• Static analysis: clippy, cargo audit, cargo deny, MSRV check, cargo bloat
• Quality gates: Binary size enforcement (< 4 MB stripped default)
• Regression testing: Tier 3 corpus runner
• Benchmarks: Tier 4 competitive benchmarks (pdfminer.six, pypdf, pdfplumber)
• Release: Automated GitHub Releases on milestone tags
• Observability: Green-run smoke test with exit handlers and workflow metadata

✅ Failure visibly blocks PR merge

• CI failures in Argo Workflows are visible in the workflow status
• Merge blockers are enforced through the CI gate

Next Steps

With Phase 0 complete, all Phase 1-7 epics are now unblocked for code review. The CI infrastructure is in place to support:

• Cross-platform builds and testing
• Quality enforcement (clippy, audit, deny, bloat)
• Regression detection
• Performance benchmarking
• Automated releases

Artifacts

• Argo WorkflowTemplates in jedarden/declarative-config → k8s/iad-ci/argo-workflows/
• CI configuration synced via ArgoCD
• Release automation ready for milestone tags

Retrospective:

• What worked: The phased approach to CI infrastructure allowed each component to be built and tested independently. The separation into 10 sub-phase coordinators made the work trackable and allowed parallel execution where possible.

• What didn't: N/A — all sub-phases completed successfully.

• Surprise: The comprehensive nature of Phase 0 — covering not just basic CI but also observability, release automation, and competitive benchmarking — provides a strong foundation for all subsequent phases.

• Reusable pattern: The pattern of breaking a large infrastructure epic into numbered sub-phase coordinators (0.1, 0.2, etc.) with clear dependencies works well for complex foundational work.
