HARD · CASE FILE
The lined evidence chest
Hard · STONE STORAGE VAULT
A chest’s outside dimensions overstate its usable space. The storekeeper needs a single regular grid of identical boxes, with four grid positions kept empty. 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
Chest construction
Outside dimensions are 60×40×28 cm. A liner occupies 2 cm at each of the six inner faces. Subtract both opposing liners from every axis.
Recover the three internal dimensions.
VERIFIED RECORD B
Evidence boxes
Each rigid box measures 18×12×8 cm. Use one common axis-aligned orientation for every box in a regular rectangular grid. Any permutation of the three dimensions is allowed; no staggering or mixed orientations.
Compare all six orientations using whole-box counts.
VERIFIED RECORD C
Access protocol
Exactly four positions in the chosen grid must remain empty for access. Maximise occupied positions after reserving those four. No weight limit applies.
Subtract the reserve from the best physical grid, not from an outside-volume ratio.
CONTEXT NOTE
Chest history
The chest was once used for maps. That history adds no storage allowance.
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 Oren Bell occupies slot 5 (Review 5).
- The event involving “Packet Cedar” occurs earlier than the event involving “Packet Birch”, without claiming they are consecutive.
- The event handled by Pera Dean occurs earlier than the event handled by Inez Shore, without claiming they are consecutive.
- The event involving “Packet Dune” occurs immediately before the event at Seal station (consecutive rows, with no event between them).
| Packet | Proposed analytical answer |
|---|---|
| Packet Amber | 24 boxes |
| Packet Birch | 32 boxes |
| Packet Cedar | 28 boxes |
| Packet Dune | 23 boxes |
| 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 Review bench occupies slot 3 (Review 3).
- The event handled by Tavi Cole occurs immediately before the event involving “Packet Amber” (consecutive rows, with no event between them).
- The event handled by Tavi Cole and the event handled by Pera Dean are exactly 2 positions apart, with 1 intervening event; this alone gives no direction.
Use each column’s choices exactly once. Verified relationships govern the board; proposed answers and later recollections do not override them.
RECONSTRUCTION RECORD
Cross-check and accounts
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 Dispatch shelf and the event involving “Packet Elm” are exactly 3 positions apart, with 2 intervening events; this alone gives no direction.
- The event handled by Pera Dean occurs earlier than the event at Intake counter, without claiming they are consecutive.
- The event handled by Tavi Cole and the event at Seal station are exactly 4 positions apart, with 3 intervening events; this alone gives no direction.
Use each column’s choices exactly once. Verified relationships govern the board; proposed answers and later recollections do not override them.
