Target Architecture Progress Snapshot¶
Date: 2026-05-28 Source of criteria: docs/TARGET_ARCHITECTURE.md Evidence anchors: docs/PROJECT_STATUS.md, runtime/tooling/docs state
Method¶
- Each Definition-of-Done criterion is scored in [0.0, 1.0].
- Pillar % = average(criteria) * 100.
- Overall % = average(pillar %).
This is a planning score, not a replacement for CI pass/fail gates.
Pillar Scoring¶
1) Durability (Temporal-inspired)¶
Criteria scoring:
- Survive restart without semantic drift: 0.60
- Retry/timer/resume explicit and test-covered: 0.80
- Checkpoint/replay API backward compatibility: 0.80
Pillar completion: 73%
Main gaps:
- Durability contract baseline is now formalized and CI-verified, but workflow-history durability is not yet Temporal-grade.
- Process restart continuity is covered at baseline level, but not yet expanded to full canonical durable orchestration semantics.
2) Contracts, Artifacts, Promotion (Dagster/dbt-inspired)¶
Criteria scoring:
- Orchestrated reproducible pipeline stages: 0.60
- Traceable lineage source -> artifacts: 0.50
- CI/local equivalent governance outcomes: 0.80
Pillar completion: 63%
Main gaps:
- Pipeline orchestration is strong but still custom-script centric.
- End-to-end lineage is present in pieces, not yet unified as a first-class pipeline lineage model.
3) Policy and Tenancy (Kubernetes/OPA-inspired)¶
Criteria scoring:
- Externally explainable and auditable policy decisions: 0.89
- Tenant isolation consistency: 0.94
- Existing runtime safety controls preserved: 0.90
Pillar completion: 92%
Main gaps:
- OPA adapter wiring and tenant-scoped policy-bundle lifecycle verification are in place, including explicit environment promotion controls in manifest governance checks.
same_tenantruntime enforcement, 8-capability rollout, channel-level probes, and HTTP/MCP transport probes are in place; broader registry rollout is still pending.
4) Developer Experience and Distribution (Stripe-like/Vercel-like)¶
Criteria scoring:
- Time-to-first-success measured and improved: 0.55
- Docs/examples parity-validated: 0.78
- Environment promotion flow documented/reproducible: 0.65
- OSS baseline without paid SaaS: 1.00
Pillar completion: 75%
Main gaps:
- DX metrics trend and initial SLO evaluation are now in place, but thresholds still need progressive hardening.
- Preview/promote/rollback environment UX is now formalized at baseline; remaining work is operational polish and broader adoption evidence.
- Cross-workflow release gate and lineage are implemented at baseline; remaining work is strategic consolidation depth rather than missing core controls.
Overall Completion¶
Overall target architecture completion: 75%
Computation:
- Durability: 73%
- Contracts/artifacts/promotion: 63%
- Policy/tenancy: 92%
- DX/distribution: 75%
- Overall average: 76%
What Is Missing Next (Priority Order)¶
- Temporal-grade durable orchestration layer beyond current durability contract baseline.
- Orchestrated delivery lineage model for contract/artifact/promotion flow.
- OPA staged enforcement policy hardening and CI/branch-level enforcement for environment promotion controls.
- DX SLO hardening and deploy-flow latency instrumentation.
Notes¶
- LangGraph remains optional integration surface and is not scored as a mandatory core pillar.
- Score reflects strategic target alignment, not capability coverage (which is already high).
- Production operations baseline is now explicitly documented in docs/PRODUCTION_READINESS.md.
