Through the stage hatch
Medium · STONE PUPPET THEATRE
Four rigid framed panels are waiting at a rectangular hatch. Only flat quarter-turns are allowed; panels cannot tilt, bend or pass diagonally. Also reconstruct the review register: it records who examined which source, independently of whether their later proposed answer is correct. Review slots describe order, not travel or clock times.
Read the case file below, or open the interactive desk to examine records, keep notes and submit your reasoning. These are the case materials, without the solution.
Your assignment
Whose panel can pass through?
- The analytical records answer the analytical question; worksheet records establish the review reconstruction. Candidate proposals and supplementary recollections are claims to test.
- There are 2 ordered events. Use each listed person and item once in its column. “A immediately before B” means A is in the row directly above B, with no row between them.
- 4 verified records support the complete submission. Keep the separate context note out of the proof.
- No outside facts or unstated exceptions are required. The complete board and report are assessed together.

Case records
Read each record on its own terms. A claim made by a person is different from a fact established by an independent record.
PRIMARY RECORD
Hatch measurement
The clear hatch opening is 50 cm wide and 40 cm high. A panel must fit within both dimensions.
This establishes the opening size.
LINKED RECORD
Panel inspection
Panels must stay flat. They may be turned by 90 degrees. Verified panel sizes: Lio 38 × 48 cm; Mara 42 × 49 cm; Neri 39 × 51 cm; Olin 41 × 52 cm.
This supplies sizes and allowed orientation changes.
CONTEXT NOTE
Stage plan
Every panel depicts a different tree for Act Two.
The painted subjects do not change physical size.
RECONSTRUCTION RECORD
Review register
This is the same investigation’s document review record. There are 2 ordered events, labelled Review 1, Review 2. Each listed person and item occurs exactly once. These slots describe record order, not times from the analytical problem.
- The event reviewed by Olin West occupies slot 1 (Review 1).
Use each column’s choices exactly once. Verified relationships govern the board; proposed answers and later recollections do not override them.
RECONSTRUCTION RECORD
Review cross-check
The relationships below were verified independently. “A immediately before B” means A is in the row directly above B, with no row between them. Keep relationships from all worksheet sources together.
- The event involving “Hatch measurement” occupies slot 1 (Review 1).
Use each column’s choices exactly once. Verified relationships govern the board; proposed answers and later recollections do not override them.
Questions to resolve
Match every recorded item to its handler or reviewer.
- Hatch measurement

Build your finding
Compare the records with each account. Work out what the evidence establishes, then separate that finding from anything it does not prove.
