The current guides were reconciled with main at 559a1b8 on 4 October 2026. The audit records source evidence, corrections, validation and remaining product limits. Brand documents the visual assets.
The tool registry design, with its pre-forged tools catalog and workflow catalog, proposes a public catalog of installable tools and workflows; its reference entries live under catalog/. Documents under plans, design studies, superpowers specs and superpowers plans preserve dated design and implementation work. The service design, context research, 27B-class local model research, diagnostics and provenance explain decisions; they are not installation or current API references.
