HARD · CASE FILE
The catalogue strip order
Hard · WILLOW BOOK ROOM
Three catalogue strips were stored out of order. Their sequence numbers and marked letters recover a shelf code only when combined with the extraction rule. The archive retained the competing reconstructions in separate packets. Rebuild their custody events, identify the proposal supported by the analytical records, then name that packet’s recorded handler. The packet events form a separate ordered register; do not substitute a calculated clock time for a review-slot label.
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
Who handled the packet containing the supported reconstruction?
- The analytical records answer the analytical question; worksheet records establish the packet custody reconstruction. Candidate proposals and supplementary recollections are claims to test.
- There are 5 ordered events. Use each listed person, location and item once in its column. “A immediately before B” means A is in the row directly above B, with no row between them.
- 6 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.
VERIFIED RECORD A
Recovered strips
Strip X contains A B C D; Y contains E F G H; Z contains I J K L. Spaces only separate individual letters.
Use these exact letter positions.
VERIFIED RECORD B
Binding marks
The authorised strip order is Z, X, Y. On each strip, use positions 2 then 4, counting from one.
Extract the same two indexed letters from each strip in order.
VERIFIED RECORD C
Deletion instruction
After concatenating the six extracted letters, delete positions 2 and 5 of that original six-letter string simultaneously. Do not renumber after the first deletion.
Distinguish simultaneous deletion from sequential deletion.
CONTEXT NOTE
Binding thread
The strips were tied in red thread. Its colour adds no ordering rule.
This describes the setting; it does not establish the requested result.
RECONSTRUCTION RECORD
Packet proposal index
This is the same investigation’s packet custody record. There are 5 ordered events, labelled Review 1, Review 2, Review 3, Review 4, Review 5. Each listed person, location and item occurs exactly once. These slots describe record order, not times from the analytical problem. Each packet contains the proposed reconstruction shown in the index. Solve the original three analytical records to identify the supported proposal, then trace its packet to its handler. Control packets have no proposal and cannot be the target.
- The event handled by Cora Reed occupies slot 4 (Review 4).
- The event handled by Dev Holt occurs earlier than the event involving “Packet Amber”, without claiming they are consecutive.
- The event involving “Packet Birch” occurs earlier than the event at Reading desk, without claiming they are consecutive.
- The event handled by Aria Vale and the event at Dispatch shelf are exactly 2 positions apart, with 1 intervening event; this alone gives no direction.
| Packet | Proposed analytical answer |
|---|---|
| Packet Amber | JLFH |
| Packet Birch | JBDH |
| Packet Cedar | JDFH |
| Packet Dune | JBDF |
| Packet Elm | Control packet: no analytical proposal |
Use each column’s choices exactly once. Verified relationships govern the board; proposed answers and later recollections do not override them.
RECONSTRUCTION RECORD
Custody sequence
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 at Seal station occupies slot 4 (Review 4).
- The event handled by Beni Moss occurs earlier than the event involving “Packet Birch”, without claiming they are consecutive.
- The event handled by Beni Moss is the same event as the event involving “Packet Amber”.
Use each column’s choices exactly once. Verified relationships govern the board; proposed answers and later recollections do not override them.
