+# REQUIRES INITIALISATION
+
+**This repository is not finished being set up.** 2 substitution token(s) across 1 file(s) still have no value.
+
+## Why this is not already done
+
+This repo was created from `hyperpolymath/rsr-template-repo`. The mint
+(`just repo-init`) fills every token that has a single mechanical answer —
+owner, repo, author, dates, licence, branch — and it has done so here.
+
+The tokens below are the ones it *deliberately cannot* answer. They need a
+decision or a fact that exists only in your head: what this project is for,
+what command builds it, which port the service listens on, whether a PGP key
+is held at all. The template's own token vocabulary says as much — you cannot
+sensibly answer "required invariants" in a thirty-second bootstrap.
+
+They were left **visibly unfilled on purpose**. The alternatives were both
+worse: inventing plausible values would put confident falsehoods into a
+security policy and an architecture document, and silently deleting the
+sections would hide the fact that a decision is owed. A visible gap is
+honest; a fabricated answer is not.
+
+## Do not delete this file until every item below is resolved
+
+This file is the only marker that the work is outstanding. Deleting it early
+does not finish the setup, it just conceals it — and the next person or agent
+to arrive will reasonably assume the repo is complete.
+
+- **If you are a person:** delete this file yourself once the last item is done.
+- **If you are an agent:** resolve what you legitimately can, leave the rest,
+  and delete this file only when no token below remains anywhere in the tree.
+  Do not delete it to make a gate go green.
+
+Re-running the estate top-up tool will remove this file automatically once
+nothing is outstanding, so the safest way to finish is to fix the tokens and
+let the check confirm it.
