The sentence, complete
On the day you arrived, this sentence was gibberish. Today you read it unassisted, and prove something harder. Five incidents strike it in no particular order. Each one opens with a brief on the figure. You tap the clause under attack, then you give the verdict on what a well-built system does about it. No station numbers. No safety net. Hold the sentence.
Incident — the hostile payload: A payload arrives reading quantity: -2 (a client bug, or the hand-crafted request Module 5 taught you to expect). Tap the clause under attack.
“The client sends an authenticated API request to the backend. The backend validates the payload, stores the data in a relational database, publishes an event to a queue, and an asynchronous worker processes the event and sends a notification.”
Incident 1 is live. Read the brief above, then tap the clause under attack in the sentence.
