Sprint 0208 · Experience & SDKs
Topic & Scope
- Build a reproducible SDK generator toolchain and shared post-processing layer that stays air-gap safe.
- Ship alpha SDKs (TypeScript, Python, Go, Java) aligned to portal APIs with consistent auth/telemetry helpers.
- Connect SDK outputs to CLI and Console data providers; package offline delivery bundles with provenance.
- Evidence: updated generator pipelines, release configs, and signed artifacts across npm/PyPI/Maven/Go proxies.
- Working directory:
docs/implplan(planning) with execution insrc/Sdk/StellaOps.Sdk.*.
Dependencies & Concurrency
- Upstream sprints: Sprint 120.A (AirGap), 130.A (Scanner), 150.A (Orchestrator), 170.A (Notifier) for API and events readiness.
- Peer/consuming sprints: SPRINT_0201_0001_0001_cli_i (CLI), SPRINT_0206_0001_0001_devportal (devportal/offline bundles), SPRINT_0209_0001_0001_ui_i (Console/UI data providers).
- Concurrency: language tracks can parallelize after SDKGEN-62-002; release tasks follow generator readiness; consumer sprints can prototype against staging SDKs once B wave exits.
Documentation Prerequisites
- docs/README.md; docs/07_HIGH_LEVEL_ARCHITECTURE.md; docs/modules/platform/architecture-overview.md.
- docs/modules/cli/architecture.md; docs/modules/ui/architecture.md.
- API/OAS governance specs referenced by APIG0101 and portal contracts (DEVL0101) once published.

Wave Coordination
- Single wave covering generator and release work; language tracks branch after SDKGEN-62-002.
Wave Detail Snapshots
| Wave | Window (UTC) | Scope | Exit criteria | Owners | Status |
|---|---|---|---|---|---|
| A: Generator foundation | 2025-11-25 → 2025-12-02 | SDKGEN-62-001..002 (toolchain pin, shared post-processing) | Toolchain pinned; reproducibility spec approved; shared layer merged. | SDK Generator Guild | Planned |
| B: Language alphas | 2025-12-03 → 2025-12-22 | SDKGEN-63-001..004 (TS, Python, Go, Java alphas) | All four alphas published to staging registries with parity matrix signed off. | SDK Generator Guild | Planned |
| C: Release & offline | 2025-12-08 → 2025-12-29 | SDKREL-63-001..64-002 (CI, changelog, notifications, offline bundle) | CI pipelines green in staging; changelog automation live; notifications wired; offline bundle produced. | SDK Release Guild · Export Center Guild | Planned |
Interlocks
- API governance: APIG0101 outputs for stable schemas; required before Wave A exit.
- Portal contracts: DEVL0101 (auth/session) inform shared post-processing; consume before Wave A design review.
- Devportal/offline: SPRINT_0206_0001_0001_devportal must expose bundle manifest format for SDKREL-64-002.
- CLI adoption: SPRINT_0201_0001_0001_cli_i aligns surfaces for SDKGEN-64-001; needs Wave B artifacts.
- Console data providers: SPRINT_0209_0001_0001_ui_i depends on SDKGEN-64-002; needs parity matrix from Wave B.
- Notifications/Export: Notifications Studio and Export Center pipelines must be live before Wave C release window (tasks 11–12).
Upcoming Checkpoints
- 2025-11-25: Toolchain decision review (SDKGEN-62-001) — decide generator + template pin set.
- 2025-12-02: Shared post-processing design review (SDKGEN-62-002) — approve auth/retry/pagination/telemetry hooks.
- 2025-12-05: TS alpha staging drop (SDKGEN-63-001) — verify packaging and typed errors.
- 2025-12-15: Multi-language alpha readiness check (SDKGEN-63-002..004) — parity matrix sign-off.
- 2025-12-16: Deliver parity matrix and SDK drop to UI/Console data providers (feeds SPRINT_0209_0001_0001_ui_i).
- 2025-12-22: Release automation demo (SDKREL-63/64) — staging publishes with signatures and offline bundle.

Decisions & Risks
- Toolchain pinned (OpenAPI Generator 7.4.0, JDK 21) and recorded in repo (
TOOLCHAIN.md,toolchain.lock.yaml); downstream tracks must honor lock file for determinism. - Dependencies on upstream API/portal contracts may delay generator pinning; mitigation: align with APIG0101 / DEVL0101 milestones.
- Release automation requires registry credentials and signing infra; mitigation: reuse sovereign crypto enablement (SPRINT_0514_0001_0001_sovereign_crypto_enablement.md) practices and block releases until keys are validated.
- Offline bundle job (SDKREL-64-002) depends on Export Center artifacts; track alongside Export Center sprints.
- Shared postprocess helpers copy only when CI sets
STELLA_POSTPROCESS_ROOTandSTELLA_POSTPROCESS_LANG; ensure generation jobs export these to keep helpers present in artifacts.
Risk Register
| Risk | Impact | Mitigation | Owner | Status |
|---|---|---|---|---|
| Upstream APIs change after generator pin | Rework across four SDKs | Freeze spec version before SDKGEN-63-x; gate via API governance sign-off | SDK Generator Guild | Open |
| Registry signing not provisioned | Cannot ship to npm/PyPI/Maven/Go | Coordinate with sovereign crypto enablement; dry-run staging before prod | SDK Release Guild | Open |
| Offline bundle inputs unavailable | Air-gapped delivery slips | Pull docs/specs from devportal cache; coordinate with Export Center | SDK Release Guild | Open |
