   `/tools/bea`; the file is not uploaded or persisted.
 - `tools/bea/+page.svelte` owns selected files, processed archives, pending work, and the
   thumbnail-width preference. Thumbnail width is the only persisted UI setting and uses localStorage.
+- The loaded workspace renders `BeaWorkspaceControls.svelte`, a top-aligned toolbar with the
+  workspace status and two archive lifecycle actions:
+  - **“Neue ZIP bearbeiten”** (replace) opens a ZIP picker and, after the user confirms the
+    replacement dialog, calls `replaceWithZipFiles(files)` which resets the workspace and enqueues the
+    new files against the incremented generation. Files picked for replacement stay in temporary
+    component state until confirmation; cancelling the picker or the dialog must never mutate the
+    current workspace.
+  - **“Weitere ZIP hinzufügen”** (append) lives in the settings popover, uses the plain append path
+    (`handleFilesSelected`), and never clears current archives. Keep the two labels distinct:
+    replace is “Neue ZIP bearbeiten”, append is “Weitere ZIP hinzufügen”.
+- `BeaWorkspaceControls.svelte` owns only ephemeral UI state (popover/dialog open state and pending
+  replacement files). The route remains the source of truth for files, jobs, archives, and the
+  persisted thumbnail width.
+- `resetWorkspace()` is the single teardown helper: it increments `archiveGeneration` and clears
+  selected files, processed archives, and jobs. Never clear those arrays without going through it.
+- Accepted ZIP types and the file filter for the dropzone and both compact pickers are centralized in
+  `src/lib/zip-selection.ts`; `ZipFilePicker.svelte` resets its input after every selection so the
+  same file can be chosen again.
 - ZIP files are processed concurrently. `archiveGeneration` prevents results from an old batch from
-  reappearing after the user deletes all archives.
+  reappearing after the user deletes all archives **or** confirms a replacement.
 - `ProcessedZipArchiveEditor.svelte` edits one archive and emits immutable replacements through
   `onArchiveChange`; the route-level archive array remains the source of truth.
 - Attachments may remain loose or belong to exactly one sub-document. Drag-and-drop supports
