fix: prevent workspace overwrites.

 - In Playwright tests, prefer accessible selectors first: `getByRole`, `getByLabel`, `getByText`, and explicit accessible names.
 - Avoid `locator()` for interactive controls when a semantic selector is available.
 - Use `locator()` only as a fallback for cases without reliable semantics (for example: document root `html`, structural class assertions, or implementation-only hooks).
+- For known WebKit HTML `<dialog>` top-layer issues, prefer a stable dialog id locator and `evaluate`-based click for dialog confirmation controls.
 - When testability needs improvement, prefer adding accessibility semantics (`role`, `aria-label`, `aria-labelledby`) over introducing new id-only selectors.

+# Playwright Testing Notes
+
+## WebKit and HTML Dialog Overlays
+
+WebKit can be sensitive to Playwright actionability checks when interacting with
+HTML `<dialog>` overlays. In some flows, role-based or standard click actions can
+time out even when controls are visibly rendered and usable.
+
+Use this fallback pattern for dialog confirmation flows when WebKit flakes:
+
+1. Target the dialog by stable id (for example: `#clear-confirm-dialog`) instead
+   of a broad `getByRole('dialog')` selector.
+2. Use `evaluate`-based click for submit/confirm controls inside the dialog.
+3. Scope text assertions to the dialog locator to avoid matching background UI.
+
+Keep accessible selectors as the default in tests. Use this dialog fallback only
+for known WebKit top-layer interaction issues.

 ## Current Workspace Selection On Load
 
-When the app loads or the selected repository changes, the app selects a workspace from IndexedDB using repository-scoped records only.
+When the app loads, workspace restore scope depends on whether a repository is selected.
+
+- If a repository is selected: use repository-scoped records only (`repo` match).
+- If no repository is selected: evaluate all stored workspace records.
 
 Selection order:
 
-1. Load records for the currently selected repository (`repo` match).
-2. Compute a preferred id from in-memory state:
+1. Load candidate records using the scope above.
+2. Compute preferred candidates from in-memory state:
 
-- Existing in-memory active record id when available.
-- Otherwise canonical id derived from current repository + head.
+- Preferred by id: existing in-memory active record id when available.
+- Preferred by workspace key: current repository + head (`workspaceKey`).
 
-3. If the preferred record exists and is `active`, select it.
-4. Otherwise select the first `active` record in that repository.
-5. Otherwise select the preferred record if present.
+3. If preferred-by-id or preferred-by-key exists and is `active`, select it.
+4. Otherwise select the first `active` record in candidates.
