# 29-Nov-2025 · StellaOps – Mid-Level .NET Onboarding (Quick Start)

**Why now:** The Docs ladder needs a deterministic, offline-ready quickstart to unblock module dossier refreshes and align mid-level .NET contributors with DSSE/VEX requirements.

## Scope
- Provide a 1–2 day runway for mid-level .NET engineers to become productive on StellaOps.
- Emphasise determinism, offline posture, DSSE/in-toto usage, and the canonical data model.
- Pair this advisory with the living guide at `docs/onboarding/dev-quickstart.md`.

## Required artefacts (MVP for DONE)
- Update `docs/onboarding/dev-quickstart.md` with deterministic/offline steps, DSSE/key-handling, and DB matrix pointers.
- Cross-links in `docs/README.md` and `docs/modules/platform/architecture-overview.md` to the quickstart.
- Sprint tracker: `docs/implplan/SPRINT_0300_0001_0001_documentation_process.md` row 3 marked DONE with Execution Log proof.

## Determinism & Offline
- Use fixed seeds and pinned toolchain versions for any sample commands.
- Avoid live network calls; prefer cached feeds/mirrors and note mirror paths.

## Next actions
- Land the cross-link updates and note completion in the sprint Execution Log.
