Merge Risk: 🔵 Low · up to The heatmap adds slot-level hot-key diagnostics, but keyboard users cannot access node details and an all-failed slot scan can appear as an empty successful result. These issues can mislead or exclude users during troubleshooting, though they do not affect stored data or service operation. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Expose node tile data to assistive technology.
Line 88 renders each tile as an unlabeled div. The node name, hot-key count, and access count are available only through mouse events. Screen-reader users cannot inspect the node heatmap.

Show node failures in the empty slot state.
When groups is empty and failedNodeCount is positive, this branch returns before the partial-results message at lines 187-191. An all-failed scan appears to be a successful result with no hot slots. Include the failed-node count in this empty state.

Use a typed response tuple instead of this unknown cast.
HotKeysResponse.hotKeys is still declared as [[]] at Line 8. This cast bypasses type checking for the new slotId position. Define a shared raw-response tuple type, declare hotKeys with it, and map hotKeys directly. Otherwise a tuple-order change can silently drop or misread slotId, which makes the Slots view incomplete or incorrect.
Proposed type-safe change
+type HotKeyMetricsEntry = [string, number, number | null, number, number?]

type HotKeysResponse = {
- hotKeys: [[]]
+ hotKeys: HotKeyMetricsEntry[]

group.nodeId is a string (typed at line 17, set from row[4] at line 46). flatMap spreads its callback's return value — and strings are iterable,
so returning a string like "127-0-0-1-7000" flattens into individual characters ["1","2","7","-",...].
Signed-off-by: nassery318 <nassery318@gmail.com>
flatMap only unpacks arrays, not strings - so this was already returning whole node ids, not characters. Switched to .map().filter() anyways since it reads more clearly. Console log results: |

Description
Adds a Slot Heatmap view to the Hot Keys feature and threads slotId through the full pipeline (metrics collector → server aggregation → Redux → UI). The existing single-view "Node Heatmap" modal becomes a tabbed Heatmap modal with Nodes and Slots tabs.
