docs/contributing.md — a descriptive guide to the established patterns, derived from
the existing code: architecture/layering, CQRS handler conventions, LanguageExt
functional style, Blazor/MudBlazor UI, EF Core + dual-provider migrations, the FFmpeg
pipeline pattern, naming/formatting/analyzers, testing, and build/CI — each with
concrete file references — plus the deviation policy (match the established style;
diverge only with a concrete, stated reason). Several sections are now CI-enforced
(#12 layering, #15 analyzers, #13 migrations, #11 golden tests). CLAUDE.md points to
it so it's loaded as project guidance.
Survey across the sections done with parallel read-only agents; all file references
verified to exist.
