Protocol 4 shipped on 2026-08-19 as sidecar v2.0.0 and overlay v1.0.0, paired in bundle 2026.08.19. Three documents still said 3. INTEGRATION.md contradicted itself: its event catalog fully documents the protocol-4 kinds, including a subsection headed "On Protocol 4", while its normative section 2 still declared X-UOLink-Version: 3, "protocol": 3 in /health and ws.hello, and a worked JS client sending "3". That is the contract a third-party integrator implements against, so it mattered most. Section 2 now states the current version and what shipped it, and gains a v4 paragraph alongside v2 and v3. The "(Protocol 3.0)" markers on individual features are left alone - those record which version introduced a kind and are correct. Two stale examples the audit had not spotted: the --print-config sample reported version 0.1.0, and the minimal browser client told readers to check ev.protocol === 1, a leftover from protocol 1. INSTALL.md is the one that actively misconfigured a real install. Line 413 is the "Protocol version" value an operator pastes into Admin -> Shard, and the document's own troubleshooting table says a stale number comes back as a 409 that "looks exactly like your shard going offline". Corrected along with the stale bundle, overlay and sidecar versions throughout, including Appendix A's copy-pasteable curl commands, which pointed at overlay v0.1.1 and sidecar v1.1.0. v4.md still said the cutover had not happened. It has. Its outstanding- work note said the five-rung shard visibility walk was "outstanding for the cutover", which is now self-contradictory - so it says plainly that the cutover shipped without it and no result is recorded anywhere. guild.roster carries actor objects for every member of every guild, the widest surface any protocol version has added to that check, so it is worth walking against the released pair. No code or contract changes. Every value verified against the Gitea API: link main sidecar/src/main.rs PROTOCOL_VERSION, servuo-plugins overlay.toml, and current.json on the installer bundles branch.

Runic Gateway — Documentation
Central documentation for the Runic Gateway platform. The docs here were extracted from the two code repositories (with full commit history preserved) so they live in one place, independent of either codebase.
Layout
website/ docs from the website core (Node/Express + MariaDB + React/Vite)
modules/ docs for installable game modules — one directory per module id
link/ docs from the ServUO bridge (C# plugin + Rust sidecar + Node WS)
android/ docs from the native Android client (Kotlin + Jetpack Compose)
installer/ docs for the installer that deploys a shard's bridge components
ci/ cross-cutting CI/quality notes
Setting up a shard? installer/INSTALL.md is the operator guide, and
the installer is the supported path: one binary deploys the plugin overlay, installs the uo-link
sidecar as a service, and hands you the values the website needs.

modules/
Documentation for installable game modules aggregates here rather than in each module's repo (MODULE_SYSTEM.md §2.10). The website core knows nothing about any particular game; a module is what makes it a site for one.
| Doc | What it covers |
|---|---|
| uo/ | module-uo — the Ultima Online module: what it serves, what it owns, and what an operator needs |
| rust-dryrun.md | A written, deliberately unimplemented module-rust — the test that the module contract generalises past the game it was extracted from |

| INTEGRATION.md | How the website integrates with the uo-link sidecar |

installer/
