Capstone: QUILLDROP

One workstation, one folder, one list of times. Ten programs, none longer than eighteen lines, take it to a signed handover.

Written for Mutant v2.6.1. Every program and output on this page is that release’s own file.

Preview. This module is not published yet: it opens once every builtin it uses has cleared review at the pinned release.

How did it start

The scene, the lure, the download and the binary: beats 1 to 4.

1. The brief

   Current

   A freight company’s finance team cannot open its quarterly close. The files are where they should be, the right size, and they open to garbage.

   IT rebuilt the machine before anyone imaged it. What is left is one triage collection from an accounts-payable workstation: a folder of files, and a bodyfile giving four timestamps for every object that was ever on it, including the ones that are not there any more. No memory, no packets, no disk image.

   That is enough.
