-  - **Element** (web, desktop, iOS, Android): on the sign-in screen, click *Edit* next to
-    "Homeserver" and enter `https://matrix.inference.coop`, then sign in with your co-op
-    account. (On [app.element.io](https://app.element.io) or the desktop/mobile apps alike.)
-  - **FluffyChat, Cinny, SchildiChat** or any other client: look for the "custom homeserver"
-    / "other server" option in the client's login screen and enter the same address.
-  - Your co-op account and your existing Matrix account on another server (e.g.
-    matrix.org or a personal homeserver) are separate identities — keep whichever you
-    like for co-op rooms; both can join. Invites go to your co-op account by default.

-Federation is enabled (delegated via `.well-known/matrix/server` on the bare
-domain, port 443), so members can also join from any homeserver they already
-use. The `@inference-bot:inference.coop` admin account (used by the portal
-for invites) has no password — token lives in the portal env.

+## Gateway version and security update policy
+
+The LiteLLM gateway is pinned to an **exact upstream tag** in
+[`code/litellm`](https://git.inference.coop/code/litellm) (currently
+`v1.84.0`). Two reasons:
+
+1. **CVE fix line.** A member security review (Oct 2026) found the prior pin
+   (`main-v1.74.0-stable`) sat below the fix line for two published
+   vulnerabilities: CVE-2026-35029 (authorization bypass on
+   `/config/update`, fixed in 1.83.0, with documented in-the-wild probing)
+   and CVE-2026-59822 (MCP session auth bypass, fixed in 1.84.0, listed in
+   the CISA Known Exploited Vulnerabilities catalog). `v1.84.0` is at or
+   above both fix lines.
+2. **Floating-tag drift.** `main-v1.74.0-stable` is a *floating* tag — the
+   registry silently moved it to a newer build. A rebuild intended as a
+   no-op therefore pulled different bits and triggered a full schema
+   migration, which is how the 2026-10-02 outage happened (see below).
+
+Rule: **never pin a floating tag** (`main-*` / `latest`); always the exact
+version tag. When upgrading, expect the first boot after the upgrade to take
+10–15 minutes (prisma migration with internal retries) — plan the restart
+window accordingly.
+
+CORS: the gateway answers browser preflights only for
+`https://chat.inference.coop` (via LiteLLM's native
+`LITELLM_CORS_ORIGINS`). The old `LITELLM_CORS_ALLOWED_ORIGINS` name
+(our v1.74.0-era sed-patch variable) is dead — v1.84.0 reads the native
+name only.
+
+## Incident log
+
+**2026-10-02 — gateway outage after security-upgrade rebuild.** A Cloudron
+update triggered by the CVE report rebuilt the app image; the floating
+`main-v1.74.0-stable` tag had moved to newer bits (v1.84.0-era), so the
+rebuild changed the running version and kicked off a full prisma DB
+migration that takes 10–15 minutes per boot with internal timeouts/retries.
+The gateway was down ~50 minutes (04:50–05:34 UTC); no data loss. Repairs:
+version pinned to the exact tag in the repo (PR
+[code/litellm#1](https://git.inference.coop/code/litellm/pulls/1) — pending
+merge), `LITELLM_CORS_ORIGINS` set as a Cloudron env var (the upgrade had
+silently reverted CORS to `*`), packaging synced to mirror the live
+deployment. Also during the incident: the domain's authoritative
+nameservers (yoursrs.com) were intermittently unreachable, briefly failing
+resolution of some hostnames (git, portal) — transient registrar-side
+issue, self-recovered, no records were wrong.
