+## Change Log
+
+### 2026-07-17 – Repository structure diagram updated (removal of `apps/`)
+
+**Reason**
+
+The originally planned `apps/` workspace (containing `apps/storybook` and `apps/docs`) was never adopted in this form during implementation. Storybook was instead kept inside `packages/luna-charts` alongside the component source it documents, and the documentation workspace (`docs/`) was placed directly at the repository root rather than nested under `apps/`. The repository structure diagram in this ADR no longer matched the actual repository layout, while the Getting Started documentation (`project-structure.mdx`) already reflected the current structure.
+
+**Changes**
+
+* Removed the `apps/` directory (and its `storybook/` and `docs/` subentries) from the structure diagram
+* Corrected the `docs/` path to reflect the actual Starlight content location (`docs/src/content/docs/architecture/`)
+* Added the `adm/` folder to the diagram, alongside `adr/`, since Architecture Development Method documentation is stored there as well
+* Added `.changeset/` to the diagram, as it is a workspace-level configuration directory used for release management
+* Added a note clarifying that Storybook is maintained as part of the `packages/luna-charts` package rather than as a separate app
+
+**Impact**
+
+The overall decision (pnpm-based monorepo with logical workspace separation) is unaffected. Only the illustrative directory layout was corrected to match the implemented structure. No other ADRs are impacted by this change.
