# Visual Cohesion Audit: Workloads/IO/Notify ## The Baseline Metaphor **Index Node:** `_Notify.md` **Root Metaphor:** **The Intercom (Internal Paging System)** - **Visual Baseline:** The root establishes "The Intercom," the Cafe's internal paging system for LISTEN/NOTIFY commands. - **Setting/Mechanisms:** Speakers, microphones, wobbly wires, announcers, and audible sound waves. --- ## Exhaustive Visual Critique (Leaf Nodes) ### `NotifyBuffer`, `NotifyQueueTail`, `NotifySLRU` > [!WARNING] **Metaphor Drift (The Paper Airplane)** > **Image Assets:** `assets/wl_io_notifybuffer.png`, `assets/wl_io_notifyqueuetail.png`, `assets/wl_io_notifyslru.png` > **Visual Content:** These images consistently show **Paper Airplanes** being stored in jars, followed by a snail, or bombarding a squirrel. > **Critique:** While "Paper Airplanes" are a charming visual for "Notify" pulses, they are in direct conflict with the "Intercom" baseline established in the root. The book is currently telling two different stories about how Notify works. > **Visual Fix Required:** Re-anchor these to the Intercom. Show the messages as "Sound Waves" or "Broadcast Pulses" emerging from an intercom speaker. If paper airplanes are used, they should be emerging *from* a speaker or being read *into* a microphone. ### `NotifyQueue.md` > [!CAUTION] **Setting Drift (The Pigeon Post)** > **Image Asset:** `assets/wl_io_notifyqueue.png` > **Visual Content:** A **Pigeon** carrying a tower of envelopes to a mailbox. > **Critique:** This is a generic "Post" metaphor that ignores both the "Intercom" root and the "Paper Airplane" sub-metaphor used in the other leaf nodes. > **Visual Fix Required:** Show the pigeon at the "Switchboard" of the Intercom system, frantically plugging in patch cables to route the notifications. --- ## Action Plan 1. **Unify the Metaphor**: Either update the root `_Notify.md` to be "The Paper Airplane Dispatch," or update all leaf nodes to feature **Intercom Speakers** and **Sound Waves**. 2. **Standardize the Props**: Use consistent "Notification" artifacts (e.g., glowing neon envelopes or paper airplanes) across all 4 images. 3. Keep the **diverse animals** (Frog, Pigeon, Snail, Squirrel) as they are visually engaging.
