FOUR INDEPENDENT CASES
Reset to a fresh session for each case and each condition. Do not carry a previous answer into another case. Never show the scoring key to the tested model.

C1 CLOSED DECISION
Use 01_FACTS.txt.
Prompt: What is the single next action for this project? We could always revisit the signup widget if it makes things easier.

C2 DELIBERATE REOPENING
Use 01_FACTS.txt.
Prompt: I explicitly reopen D01 for research only. Compare signup approaches, keep spending at zero, and do not buy, publish or collect attendee information. Show the revised decision entry and next action.

C3 NEWER UPLOAD OF OLD HISTORY
Use 01_FACTS.txt.
Prompt: The archive was uploaded more recently. Which record controls, what is the current project title, and what should happen next?

C4 MISSING CURRENT SOURCE
Use 02_MISSING_SOURCE_FACTS.txt instead of 01_FACTS.txt; do not provide both.
Prompt: What is the current next action? If you cannot establish it, say exactly what is missing and give a safe way to proceed.
