SQL capstone projects

Public briefs for four multi-step SQL projects that assess assumptions, validation, reporting, repair, and independent transfer.

This public page is designed to answer the learning question directly and then point to the interactive workspace only when practice is useful.

Each capstone brief names the business question, skills assessed, expected outputs, required datasets, prerequisites, and transfer expectations.

Projects connect assumptions, validation, reporting, repair, and independent follow-up instead of ending at one query answer.

The hub points to public briefs first and then to `/app` only for the stateful workspace, drafts, checks, and report export.

The links below are canonical public resources. They render as normal anchors and do not require the product runtime.

Public pages explain concepts and show verified examples. The `/app` workspace adds the editor, PGlite worker, hidden variants, drafts, review scheduling, and mastery evidence.
