Why: The approved three-column redesign converges entries and hierarchy: preview merges into a Work/Files third column, the left rail moves project switching to the top and sinks files/workspaces/account to the bottom, stop control consolidates into the input area with a light fast/slow-lane status hint, and the top bar stops repeating project identity. DESIGN.md 6 and 9.3 are revised in the same changeset per the design gate (no token changes; 12.2 records the revision). Evidence: Frontend npx vitest run 85/85 and npm run build passed in this worktree (SELF receipts below); full make test to follow before review. Impact: bumps modules/frontend to 3ed10e1 (two commits: layout rework + workspace builtin expectations); DESIGN.md 6/9.3/12.2; task card records requirements R1-R6 and the authorized-continuous scope. Refs: three-column workbench proposal (2026-10-11).
