+## Phase Details
+
+### Phase 6: Global Site Selection
+**Goal**: Administrators can select one or more target sites once from the toolbar and have every feature tab use that selection by default
+**Depends on**: Phase 5 (v1.0 foundation — toolbar and tab architecture in place)
+**Requirements**: SITE-01, SITE-02
+**Success Criteria** (what must be TRUE):
+  1. A multi-site picker control is visible in the main toolbar at all times, regardless of which tab is active
+  2. Selecting sites in the toolbar causes all feature tabs to default to those sites when an operation is run
+  3. A user can override the global selection on any individual tab without clearing the global state
+  4. The global site selection persists across tab switches within the same session
+**Plans**: TBD
+
+### Phase 7: User Access Audit
+**Goal**: Administrators can audit every permission a specific user holds across selected sites and export the results
+**Depends on**: Phase 6
+**Requirements**: UACC-01, UACC-02
+**Success Criteria** (what must be TRUE):
+  1. A User Access Audit tab (or panel) is accessible and accepts a user identifier and site selection as inputs
+  2. Running the audit returns a list of all access entries the user holds across the selected sites
+  3. Results distinguish between direct role assignments, SharePoint group memberships, and inherited access
+  4. Results can be exported to CSV or HTML in the same format established by v1.0 export patterns
+**Plans**: TBD
+
+### Phase 8: Simplified Permissions
+**Goal**: Permissions reports are readable by non-technical users through plain-language labels, color coding, and a configurable detail level
+**Depends on**: Phase 6
+**Requirements**: SIMP-01, SIMP-02, SIMP-03
+**Success Criteria** (what must be TRUE):
+  1. The permissions report displays human-readable labels (e.g., "Can edit files") alongside or instead of raw SharePoint role names (e.g., "Contribute") when the simplified mode toggle is on
+  2. The report shows summary counts per permission level with color indicators distinguishing high, medium, and low access levels
+  3. A detail-level selector (simple / detailed) controls whether individual item-level rows are shown or collapsed into summary rows
+  4. Toggling modes and detail level does not require re-running the scan — it re-renders from the already-fetched data
+**Plans**: TBD
+
+### Phase 9: Storage Visualization
+**Goal**: The Storage Metrics tab displays an interactive chart of space consumption by file type, togglable between pie/donut and bar chart views
+**Depends on**: Phase 6
+**Requirements**: VIZZ-01, VIZZ-02, VIZZ-03
+**Success Criteria** (what must be TRUE):
+  1. A WPF charting library (LiveCharts2 or OxyPlot) is integrated as a NuGet dependency and renders correctly in the self-contained EXE build
+  2. After a storage scan completes, a chart appears in the Storage Metrics tab showing space broken down by file type
+  3. A toggle control switches the chart between pie/donut and bar chart representations without re-running the scan
+  4. The chart updates automatically whenever a new storage scan finishes, without requiring manual refresh
+**Plans**: TBD
+
