# C-first · The four status slips · selected source

**Eligibility:** After Day 36. Unknown/zero/no-action concepts familiar; exact values/accounts held. 

## Complete original fictional account

Four fictional slips. S1: archive date 11, named Moon observation attempted, view obstructed by a roof, position unavailable. S2: date 12, observer wrote a plan but explicitly did not attempt observation. S3: date 13, no result record supplied; whether an observation occurred unknown. S4: date 14, a named paper-model planet token was measured at 0 equal paper units from the fixed baseline by a fictional helper. This is a given model measurement, not a real sky distance or learner measurement.

## Four questions

1. What do S1 and S2 say happened? Keep their difference.

2. What can we say about S3? What question could help?

3. What does 0 in S4 measure? What does it not mean?

4. Make one honest status row for a slip.
