+multi-site work for gaps, plus the published docs staleness that same audit
+turned up.
+
+### sso-manager-node v2.8.0
+- Promotion no longer orphans the demoted old master's LDAP replication --
+  `/demote` now registers itself with the new master immediately instead of
+  being left with no way to ever get a real `ldapServerId` again.
+- The Directory's site slug and the multi-site replication identity are
+  unified -- previously unrelated values that happened to share a name.
+- LDAP replication status (real vs. advertised ServerID, a `stale` flag) and
+  per-spoke detail (not just an aggregate count) on the Multi-Site modal.
+
+### theta-suite docs
+- Fixed multiple stale/contradictory claims on the published site: the
+  no-inbound relay described as "designed but not automated" (shipped
+  earlier this session), `docs/sso/replication.md` never mentioning the new
+  LDAP MMR auto-config at all, and the homepage feature list only
+  describing the old manual N-way replication.

 ## How this relates to LDAP replication
 
-[N-way LDAP replication](replication.html) is a *lower-level*, different
-mechanism: every site runs a fully independent, fully writable `slapd`, wired
-together with raw `syncrepl` environment variables, and there's no concept of
-a master or a managed join. It predates this feature and is still there for
-deployments that specifically want every site independently writable.
+[N-way LDAP replication](replication.html) is the *lower-level* mechanism
+underneath this: `slapd`'s own `syncrepl`, wired via `LDAP_SERVER_ID` +
+`LDAP_REPLICATION_HOSTS`. Originally this was hand-configured by the
+operator, separately from the join flow above, for deployments that wanted
+every site independently writable with no concept of a master.
 
-Multi-site join (this page) is the opposite design: one write authority, a
-managed onboarding flow, and automatic ongoing sync — closer to what most
-"add a second office" or "add a home-lab spoke" setups actually want. **Don't
-combine the two** — pick one per deployment.
+**When you join via this page's flow, that lower-level config is now handled
+for you.** The master auto-assigns each spoke a unique `LDAP_SERVER_ID` at
+join time and derives every site's LDAP URL from its already-known HTTPS
+endpoint — `theta-suite`'s `bootstrap/site-ldap-register.js` applies it,
+re-checked on every `setup.sh` run since the peer list grows as spokes join.
+You don't hand-set `LDAP_SERVER_ID`/`LDAP_REPLICATION_HOSTS` for a cluster
+built this way. See [Geo-Location Scaling](replication.html#automatic-config-via-multi-site-join)
+for the mechanics, and its documented limitation: the *master's* own
+replication list only updates on ITS next `setup.sh` run, not live the
+instant a new spoke joins.
+
+Still want fully independent, always-writable sites with no master/spoke
+concept at all? `CFG_LDAP_MMR_MANUAL=true` opts out of the automatic path so
+you can hand-set `LDAP_SERVER_ID`/`LDAP_REPLICATION_HOSTS` directly, same as
+before this integration existed.

 ## Configuration
 
-To enable replication, you must pass two environment variables to the `sso-manager` container:
+The container's entrypoint reads two environment variables to configure this
+-- `LDAP_SERVER_ID` (a unique integer for this node) and
+`LDAP_REPLICATION_HOSTS` (a space-separated list of every **other** node's
+LDAP URL) -- and, when both are set, automatically loads the `syncprov`
+module, enables `mirrormode`, and generates the necessary `syncrepl` blocks
+in `/etc/openldap/slapd.conf`.
 
-1. `LDAP_SERVER_ID`: A unique integer for this node (e.g., `1`, `2`, `3`). This MUST be unique across the cluster.
-2. `LDAP_REPLICATION_HOSTS`: A space-separated list of the LDAP URLs of all **other** nodes in the cluster.
+### Automatic config via Multi-Site join
 
-### Example using `theta-env` / Docker Compose
+**If you're using [Multi-Site join](multi-site.html) (`CFG_MASTER_DIRECTORY_URL`/`spoke.env`),
+you don't set these by hand.** The master assigns each spoke a unique
+`LDAP_SERVER_ID` at join time (the same way it assigns a WireGuard mesh
+index) and derives `LDAP_REPLICATION_HOSTS` from every site's already-known
+HTTPS endpoint (`ldaps://<same-host>:636`) -- `theta-suite`'s `bootstrap/
+site-ldap-register.js` applies it and re-checks on every `setup.sh` run,
+since the peer list grows as new spokes join, restarting `sso-manager` only
+when the computed config actually changed.
 
-**Site 1 (`setup.env` or `docker-compose.yml`)**
+**Known limitation**: the *master's* own `LDAP_REPLICATION_HOSTS` only gets
+recomputed when its `setup.sh` is re-run — there's no live push telling an
+already-running master about a spoke that joined five minutes ago. Re-run
+`setup.sh` on the master after bringing up a new spoke (or after promoting
+one to master) to pick up the current peer list. A spoke's own config, by
+contrast, is re-checked and applied on every `setup.sh` run there, which is
+the common/recurring event.
+
+### Manual configuration
+
+Have a topology outside a `theta-suite`-managed cluster (fully independent,
+always-writable sites, no master/spoke concept)? Set
+`CFG_LDAP_MMR_MANUAL=true` to skip the automatic path entirely and set the
+two variables directly -- without this, the automatic step runs on every
+deployment (every fresh install starts as a master) and will overwrite them.
+
+**Site 1**
 ```env
 LDAP_SERVER_ID=1
 LDAP_REPLICATION_HOSTS="ldaps://sso.site2.com:636 ldaps://sso.site3.com:636"

-Once configured, the container's entrypoint will automatically load the `syncprov` module, enable `mirrormode`, and generate the necessary `syncrepl` blocks in `/etc/openldap/slapd.conf`.

 ## User Locations
 
 When creating or editing a user, you can specify their **Location (Site)**. This maps directly to the standard LDAP `l` (localityName) attribute, allowing you to track which physical site a user belongs to natively within the directory.
