+## Narrow service-status revision
+
+- User request: make the right-hand service-status panel slightly narrower.
+- Revised implementation screenshot: `docs/superpowers/specs/assets/service-dashboard-narrow-service-1440x900.png`
+- Viewports: 1440 × 900 and 1440 × 768
+- State: authenticated dashboard with the service-status column reduced to approximately 30% of the middle row.
+
+### Iteration 5 — passed
+
+The middle grid now allocates `1.9fr` to the training chart and `0.82fr` to service status, with a 300px minimum width for the service panel. This gives the chart more horizontal space while keeping all service names, status badges, and instance counts fully visible.
+
+Browser measurements:
+
+- at 1440 × 900, chart width: 799px; service width: 345px; service share: 30.1%
+- at 1440 × 768, chart width: 799px; service width: 345px
+- clipped service cells: none at both tested viewports
+- horizontal and vertical document overflow: none at both tested viewports
+- browser console errors: none

+## Taller training-task revision
+
+- User request: increase the training-task region slightly and shorten the middle chart/service region.
+- Source visual truth: `docs/superpowers/specs/assets/service-dashboard-narrow-service-1440x900.png` plus the current user annotation.
+- Intended viewports: 1440 × 900 and 1440 × 768.
+- State: authenticated dashboard with larger task heading and table rows.
+
+### Iteration 6 — blocked
+
+The task section now uses a taller heading and table rows in both standard and low-height desktop modes. Because the middle row is the only flexible region, the additional task height is taken directly from the chart/service row while preserving the one-screen layout contract in code.
+
+Verification evidence:

+- `npm run test:dashboard`: passed

+- `npx vite build`: passed
+- browser-rendered comparison: blocked because the in-app browser rejected the local preview URL under its URL security policy
