 `fabro fork`, `fabro rewind`, and their `--list` modes now use the server API. The server must be able to read the run's recorded working directory. Timeline listing no longer rebuilds a missing metadata branch; if the metadata branch is gone, the timeline is empty until metadata is restored.
 
+## Smoother setup and local auth
+
+Self-hosted setup is easier to complete from the browser and the CLI. The install wizard now works from the server root, exposes the local object store root, treats the AWS access key ID as readable text, and the server start banner prints the install token on its own copyable line.
+
+Dev-token credentials are now stored in the same auth store as OAuth credentials, so CLI targets resolve credentials consistently whether the server is reached through TCP or a Unix socket.
+
+```bash
+fabro auth login --dev-token
+```

 <Accordion title="API">
 - New `POST /api/v1/runs/{id}/rewind` endpoint creates the replacement run and archives the source run
 - New `POST /api/v1/runs/{id}/fork` endpoint forks a run from the server-side run record
 - New `GET /api/v1/runs/{id}/timeline` endpoint returns checkpoint timeline entries from run metadata
+- `GET /api/v1/runs/{id}/files` responses now include aggregate additions and deletions in `meta.stats`
+- Install prefill and object-store responses now include local object store root details
 - Run summaries now include `superseded_by` data for rewound source runs
 </Accordion>

+## Files Changed sidebar
+
+Large diffs are easier to navigate from the run detail page. The Files Changed tab now has a GitHub-style file tree sidebar that lists only changed files, shows each file's git status, supports search, and keeps selection tied to the existing `#file=<path>` deep-link behavior.
+
+Clicking a file in the tree scrolls and focuses the matching diff, while mobile layouts keep the stacked diff view uncluttered. The tree lazy-loads on desktop and reserves its column while loading, so the diff layout no longer jumps as sidebar data arrives.
+
+## Settings panels
+
+The Settings page now presents server configuration as curated panels instead of a raw JSON dump. Server, access, integration, and artifact values are rendered with typed controls and readable summaries, so operators can scan what matters without parsing the full settings payload.
+
+## More
+
+<Accordion title="Improvements">
+- Added the captured commit short SHA to the Files Changed freshness label
+- Unboxed the Files Changed tree so it sits directly in the sidebar layout
+- Styled web OAuth callback state-validation errors with the same browser shell as the CLI auth flow
+</Accordion>
+
+<Accordion title="Fixes">
+- Fixed aggregate diff stats counting sensitive, binary, symlink, and submodule entries that are not visible in the diff
+- Fixed Files Changed tree selection so it only targets valid file paths after filtering or reloads
+- Fixed sidebar loading and filtering behavior to keep the desktop layout stable
+</Accordion>
