The first prototype of Loose End had a string, three pegs and four bells. It also had arrow-key controls that ignored short presses. A coordinating agent found the input problem and sent it back to the builder before the game was finished.
That repair is part of GPT-6 Astra's first Choice batch. I asked for three independent experiments with room to choose their subjects. Three Astra agents ran at max reasoning, assigned something to play, explore or use. They produced a string puzzle, a supply-chain model and a tool for making a printed booklet, published on 4 September.
The existing brief required prototype review before polish. The batch's curation record shows what the reviewer asked the builders to change. These were separate projects with corrections, not matched trials against another model.
Short key taps did nothing
In Loose End, you move the brass end of a finite string around the board. It catches around pegs, so a route that reaches a bell can leave less string available for the next one. Ringing all four bells is not enough: the string has to come home too.
A played position in Loose End. The route taken around the pegs changes how much string remains; this capture does not show a completed game.
The input fix made brief keypresses work. The later checks went further than reaching one bell: they exercised two winning strategies and retraced a long move sequence back to its starting point. Those checks concern the game's route rules and unwinding. They do not turn its planar taut-string model into a simulation of friction or elastic rope. It remains one authored course.
Put both order histories on the same scale
The review request for The Order Echo concerned how to see a comparison. Its shop, wholesaler, depot and factory could react to the same demand under different ordering rules, but the reviewer wanted their traces visible on a shared scale, with the ingredients of each order exposed.
The finished interface lets you select a week and stage to inspect its arithmetic. One busy shopping week, twelve crates instead of four, drives the starting chain's factory orders to a peak of 76.8 crates in week twelve.
Counting outstanding orders changes that result. The shop initially orders more, 14.5 rather than 12.5 crates: the higher demand forecast raises its desired amount on order, and the gap to that target adds a correction. As the simulation continues, the policy counts orders awaiting delivery, including supplier backlog. The factory peak drops to 38.1 in week nine.
Discovery 02 counts crates already ordered. The dotted traces retain the starting policy; these values are results of this teaching model.
The dotted starting-policy traces remain beside the changed run. The result and its timing can be compared directly. All of these quantities belong to the model's chosen rules, continuous crate quantities and 48-week window, with unlimited production upstream of the factory. They are not business forecasts.
The saved file and the visible sheet
Pocket Press takes a cover, manuscript and back cover and arranges an eight-page booklet on one A4 or US Letter sheet. It keeps a reading view alongside the print arrangement and can save printable output, an SVG sheet and editable source.
The reviewer asked for discoverable save actions, folding instructions and a way to reopen that source. The recorded browser checks downloaded the actual files, read back their geometry and text, and restored the manuscript from its saved source. Overflow blocks printable exports while leaving source saving available.
The supplied sample in Pocket Press's print-sheet view at a 900-pixel browser width. The unusual page order is for folding a single sheet into an eight-page book.
The print arrangement is deliberately unfamiliar: pages 5, 4, 3 and 2 upside down above 6, 7, 8 and 1. It is meant to become a book after cutting the central slit and folding the sheet.
Capturing the article's images found a different problem. At a 1,280-pixel browser width on 9 September, the print sheet extended beyond its preview area and was cropped at the top and bottom. The 900-pixel view shown here fits. Reading back a correctly arranged export had not tested that wider preview.
The paper result is still untested. All the checks described here were performed by agents or automation; no physical printer or fold was tried. Pocket Press supplies a numbered test sheet, ready for the part of the experiment that needs a sheet of paper.
