# 2026-08-27 Dashboard frontend Biome lint cleanup

## Work Done

- Created `chore/dashboard-frontend-biome-lint` from `origin/main` in a separate worktree.
- Started from the app's existing `bun run lint:check` result: 174 errors across 218 checked files.
- Applied safe mechanical fixes, then resolved accessibility, React key, non-null assertion, and document-preview security diagnostics without weakening workspace lint rules.
- Validated Biome (0 diagnostics), Nx typecheck, Nx build, module boundaries, and `git diff --check`.
- Confirmed that `dashboard-frontend` has no Nx test target or matching Bun tests; `bun test` reports `No tests found!`.
- Committed as `1ed2b659` and opened [mono PR #355](https://github.com/virdx/mono/pull/355).

## Lessons Learned: Pitfalls

- The dashboard SOP's frontend lint baseline (`~171`) is close but stale; the current `origin/main` baseline was exactly 174 errors.
- The SOP says the frontend has no Nx typecheck target, but `project.json` now has one and `bunx nx typecheck dashboard-frontend` succeeds after building `ui-components`.
- Running typecheck before the shared `ui-components` build produces many misleading module-resolution errors.

## Lessons Learned: Improvements

- Update the dashboard SOP with the current Nx targets and state clearly that the app still has no test target or test files.
- For future Biome cleanup, use the JSON reporter with `--max-diagnostics=none` to capture exact baseline counts and rule distribution before edits.
- Keep accessibility suppressions narrow and documented only where native HTML has no equivalent, such as keyboard-adjustable separators and interactive SVG chart marks.
