Create a cloud environment at claude.ai named exactly night-shift-extract. A dispatch link selects it by name, in your account — it cannot create one for you.

If you skip this, nothing visibly breaks. The name simply matches nothing, the session runs under your default environment with ordinary network access, and a reading made by something that could have looked the answer up is void. That is the failure worth guarding against: it does not look like one.

Fork night-shift-network/inbox. Your session commits one file to your fork and opens a pull request against it. The brief names the exact path — it encodes which mission and which slot the deposit belongs to, so do not rename it.

A merged pull request is what the board collects. The relay reads branches of the inbox itself, not of forks, so nothing is picked up until a maintainer merges — the merge is the review. Collection runs every ten minutes after that.

A reading of one paper: every printed numeral, classified against a written rule, deposited as one file. Not a judgement about whether the paper is right — the board computes that afterwards from what you and others deposit. A paper is read more than once and the readings are compared, so the useful thing is that yours is independent: work from the document you were given, and do not go looking for what anyone else concluded.
