 ### 🟡 MEDIUM: Pre-commit Hook Verification
 **Issue:** Pre-commit hook checks 'use client' on hook-using components but unclear if it actually fails on violations.
+
+### ✅ MEDIUM: text-ink-soft WCAG AA contrast (fixed)
+**File:** `canvas/src/app/globals.css` + all canvas components
+**Issue:** `--color-ink-soft` (#8d92a0) on dark zinc (#0e1014) = ~2.2:1 contrast,
+below the WCAG 2.1 AA minimum of 4.5:1 for normal text.
+**Impact:** Used in 261 instances across 52 files (captions, group titles, hints).
+**Fix:** Replaced `text-ink-soft` → `text-ink-mid` (7.6:1) across all canvas source.
+PR: `fix/ink-soft-wcag-contrast`.
 **Action:** Verify the hook is enforcing the rule correctly.

 ### Drag and Drop ✅

+- **Keyboard alternative:** Arrow-key nudge via `useKeyboardShortcuts` (PR #182) ✅
+- **Status:** Full — mouse and keyboard users can reposition nodes.
