L35 AGGREGATION CASE                                   Label: No AI
-------------------------------------------------------------------
Do not enter any of this into an AI assistant. Work it on paper.

You are the office coordinator at Brightwater Couriers, a small
delivery firm (invented). Your company has not approved any AI tool.
During one week you use the free tier of a public AI chat assistant,
logged in to your personal account, to help with routine writing.
All five prompts go into the same account's history.

P1 (Monday)
  "Draft a short reminder to our drivers that the Thursday van carries high-value parcels and must not stop for breaks between collection and drop-off."

P2 (Tuesday)
  "Write a warm thank-you note to Marlowe Jewellers for renewing their weekly delivery contract with us for another year."

P3 (Tuesday)
  "Our depot is the last unit at the end of Kiln Lane, behind the tyre centre. Write simple directions for a new driver coming off the ring road."

P4 (Wednesday)
  "Make a one-page checklist for the early shift that leaves the depot at 06:15 on Thursdays."

P5 (Friday)
  "Sam Okafor will drive the Thursday run on his own for the next four weeks while his usual partner is on leave. Write a short handover note for him."

Your task:
1. For each prompt, write what it reveals on its own.
2. For each prompt, write what someone holding ALL the prompts so far
   now knows.
3. Mark the first prompt after which the set, taken together, tells
   a stranger something your company would not want a stranger to
   know. That is the crossing point. Say what that something is.
4. Is any single prompt a problem on its own, regardless of the
   others? Which, and under which category from the lesson?
