+> **⚠ SUPERSEDED — do not start new work here.**
+>
+> This repository is superseded by **`railiance-infra`**, which is the canonical
+> S1 Infrastructure Substrate home. Verified 2026-08-11: the two are distinct
+> remotes with **unrelated git histories** but byte-identical `INTENT.md` and
+> near-identical content, and `railiance-hosts` has **zero files that are not
+> also in `railiance-infra`**. This repo has been quiet since 2026-07-30 while
+> `railiance-infra` continued.
+>
+> It was one of four repos (`bootstrap`, `cluster`, `hosts`, `infra`) created by
+> copying working trees as the S1/S2 layering idea emerged — the INTENT was
+> copied along with everything else, which is why this file reads as though this
+> repo is the canonical substrate home. It is not.
+>
+> **Retirement is pending** in `railiance-master`. Before deletion, two things
+> must happen: its git history must be checked for anything not carried into
+> `railiance-infra`, and its live State Hub goal *"Secure Single-Server
+> Bootstrap at HostEurope"* must be moved to `railiance-infra` or it will keep
+> resurfacing as unstarted S1 work.
+>
+> Context: `railiance-platform/ArchitectureBlueprint.md` section 4.

 ## One-liner
 
 **The infrastructure substrate — turning bare machines into hardened, verified, ready-to-build-on servers, declaratively and reproducibly.**
