ln-71-system-design-baseline-builder

Run this Skill to build a baseline artifact listing each driver with applicability, criticality, evidence status, source, owner, and review trigger. It expresses key scenarios as measurable source/stimulus/environment/response statements rather than vague qualities.

It is a single versioned Markdown artifact recording business context, workload and data scale, SLOs, recovery targets, security and compliance constraints, and cost envelopes. The Skill writes it to docs/architecture/system-design-baseline.md unless an equivalent document already exists.

Do not use it for target architecture design, plan review, implementation, or architecture audits. It only creates or updates the requirements baseline; downstream skills handle design, review, and auditing tasks.

Unknowns are marked UNKNOWN or UNVERIFIED and never converted into confident facts. The final verdict is INCOMPLETE when consequential drivers remain open, and BLOCKED when scope, authority, or destination prevents safe creation.

No. It only mutates the approved architecture Markdown artifact with minimal patches, preserving unrelated content. The validation checklist explicitly confirms no product code, tests, or unrelated documents changed.
