+## v0.9.1 — 2026-09-28
+
+### The mirror page is one line per model
+
+What the mirror holds used to take two table rows per file — seven columns and
+the address under them — so a sharded model filled the screen. Now each version
+is one line: model and version, the file (or "4 files" for a set), total size,
+and which catalog models use it. The address moved into a "copy address" button;
+the checksum is in the file's tooltip. A version already in use is not offered
+for serving again, and removing one warns that the catalog uses it. The header
+counts versions rather than files.
+
+## v0.9.0 — 2026-09-28
+
+### Managing people and the tenancy tree
+
+Organizations, teams and projects can now be renamed, moved and removed, and an
+approved person can be moved to another project or removed — none of which
+could be done at all before, from the web or the CLI.
+
+- **`/admin/users`** shows the whole tree, each project opening onto its people
+  and keys, with approve, move, suspend, reinstate and remove for people,
+  revoke for keys, and add, rename, move and remove at every level. A search
+  over every account sits below it. Changes update the page in place (htmx,
+  embedded in the binary) and it still works with scripts off.
+- **`llmgw org`** — `tree [--people]`, `add`, `rename`, `move`, `remove`.
+- **`llmgw users move`** and **`llmgw users delete`**.
+- **`llmgw keys list --all`** lists every key with its project and owner.
+- Every command that takes a project, team or organization accepts an id, a
+  path such as `Acme/platform/gateway`, or a unique name, and `--project` may
+  be omitted when there is only one. Users are named by id or email.
+
+Moving a person takes the keys they made with them; keys an operator issued stay
+with the project. Only empty things are removed, and a project that ever had a
+key is never removed, because usage history refers to it.
+
+### Changes
+
+- **`--project` no longer defaults to `default`** in `keys create`, `keys list`,
+  `users approve`, `users create`, `keys threads` and `keys memory`: a tree
+  built from the web has no project of that name. With one project it is
+  chosen; with several the command lists them.
+- **`keys limits --budget` is in whole units**, as the quotas page takes it,
+  rather than micro-units. `--budget 50000000` now means fifty million units;
+  divide existing scripts' figures by 1 000 000.
+
+### Fixes
+
+- `keys init` could silently move an existing team or project to another
+  organization or team by redeclaring it. It now refuses.
+- An account rejected while pending and then reinstated became active with no
+  project, and failed at its first key. Reinstating one is refused; approving
+  gives it a project. Rejecting a signup now removes it.
+
+## v0.8.8 — 2026-09-28
+
+### Fixes
+
+- **`server init --postgres` failed on Rocky Linux** with "postgresql-setup:
+  executable file not found". The PostgreSQL project's own packages (PGDG)
+  provide `postgresql-server` too, so dnf can answer that name with
+  `postgresql16-server`, which names its unit `postgresql-16.service` and keeps
+  its tools in `/usr/pgsql-16/bin`. init now finds the server unit systemd has,
+  reads the data directory from it, and runs `initdb` itself when the directory
+  is empty. A PostgreSQL that was already installed is used as it is.
+
+### Known gaps
+
+Not yet run on a real machine. Three arrangements are not handled: a
+PostgreSQL initialised with `ident` for TCP logins (the connection check fails
+and says so), one listening on a port other than 5432, and several PGDG
+versions where the highest is not the one on 5432.
+
+## v0.8.7 — 2026-09-28
+
+### PostgreSQL in one command
+
+```
+sudo llmgw server init --postgres
+```
+
+Installs PostgreSQL with the machine's own package manager when there is none,
+creates the `llmgw` role and database with a generated password kept in
+`/etc/llmgw/secrets/store-dsn`, and checks that it connects. On a control plane
+already running on SQLite it stops the gateway, copies the store across so
+every account and key survives, points `auth.store` at PostgreSQL and starts
+the gateway again; if the move fails, the gateway is started again on SQLite.
+Given on the first run, there is never a SQLite store.
+
+`server.yaml` is edited in place with its comments intact, and the previous
+file is kept beside it. A PostgreSQL that init did not install is left sized as
+it was, since something else may depend on it.
+
+The PostgreSQL installation itself has not yet run on a real machine; the move,
+the configuration edit and the rerun behaviour are tested.
+
+### Fixes
+
+- **A new control plane with no models did not start.** A configuration with
+  no static endpoints and no models was refused as having nothing to serve, so
+  under systemd the unit restarted every two seconds and nothing listened on
+  8080. It now runs as a control plane with an empty catalog.
+
+## v0.8.6 — 2026-09-28
+
+### Reverse proxy configurations
+
+`deploy/proxy/` has a Caddyfile and an nginx configuration for the client
+port, and both are attached to every release beside the binaries. They do not
+buffer streamed replies, their read timeout outlasts a model's wait before its
+first token, their body limit matches the router's, and they set
+`X-Forwarded-Proto` and `X-Forwarded-Host` themselves — llmgw marks session
+cookies `Secure` from the first and shows the second as the base URL on its
+landing page.
+
+## v0.8.5 — 2026-09-28
+
+### A control plane in one command
+
+```
+sudo llmgw server init --admin you@example.com
+```
+
+Creates the llmgw user and its directories, the certificate authority, the
+control plane's certificate for the machine's hostname and every address it
+has, `server.yaml`, the default project, and an administrator whose password is
+generated and printed once — then installs the systemd unit, starts it and
+waits until it answers. What used to be two steps of install.md is now this.
+
+Each step is skipped when its result exists, so running it again finishes an
+install that stopped and changes nothing on one that did not. `--host` adds an
+address the machine cannot see of itself (a DNS alias, a NAT or floating
+address) and reissues the certificate keeping the old ones. It never overwrites
+`server.yaml` or an authority, and certificates issued by an authority kept on
+another machine are left as they are.
+
+### Fixes
+
+- **The configuration install.md showed could not start.** An empty catalog
+  without `control.enabled: true` is refused as having nothing to serve. The
+  documentation and the file `init` writes both set it.
+
+## v0.8.4 — 2026-09-28
+
+### Node logs on the admin page
+
+Each node on the cluster page links to its logs — the agent's own, and the
+output of every engine running there — with an option to follow them. `llmgw
+ctl logs NODE` reads the same. They come over the agent's existing stream, so
+no ssh, jump host or root is needed to see what a node did. The agent keeps its
+last 2000 lines in memory; each engine its last few hundred.
+
 ## v0.8.3 — 2026-09-28
 
 Found by building a node from nothing with v0.8.2.

+| [nginx.conf](nginx.conf) | nginx, with a certificate from certbot |
+
+Both are also attached to every release.
+
+Four things both files get right, and any other proxy has to as well:
+
+- **Streaming is not buffered.** Replies are server-sent events; a buffering
+  proxy delivers them in one burst at the end.
+- **The read timeout is longer than a model's silence.** nginx's default of 60
+  seconds turns a slow first token into a 504.
+- **`X-Forwarded-Proto` and `X-Forwarded-Host` are set by the proxy**, replacing
+  whatever the client sent. llmgw uses the first to mark session cookies
+  `Secure` and the second for the base URL on its landing page.
+- **The body limit matches llmgw's** (32 MiB, `router.max_body_bytes`), so an
+  oversized request is refused before it is uploaded.
+
+Only port 8080 is proxied. Agents reach 7443 directly — it is mutual TLS with
+the cluster's own authority, and a proxy terminating it would take away the
+node identity it carries. 9090 (admin, pprof) stays on loopback; 9091
+(metrics) goes to your monitoring host only.
+
+With a proxy on the same machine, bind llmgw to loopback so nothing reaches it
+around the proxy:

-## 2. The certificate authority
+## 2. The control plane
 
-Agents authenticate to the control plane with mutual TLS, and a node's identity
-is taken from its certificate's common name. A public authority cannot supply
-these: Let's Encrypt and its peers stopped issuing certificates carrying the
-`clientAuth` usage, so nothing they hand out can authenticate an agent.
-
-Run this wherever you intend to keep the authority. It talks to nothing and
-works on files, so it does not have to be a cluster machine — and there is an
-argument that it should not be.
+On the machine that will be the control plane, as root:
 
 ```
-sudo llmgw ctl cert init-ca --dir /etc/llmgw/pki
+sudo llmgw server init --admin you@example.com
 ```
 
-That writes `ca.pem` and `ca-key.pem`. **Whoever holds `ca-key.pem` can mint any
-node's identity**, so it stays here; `ca.pem` is copied to every machine and is
-not a secret.
+That is the whole step. In order, it:
 
-Now the control plane's own certificate. Every address an agent might dial must
-appear in `--host`, bare IP addresses included — hostname verification reads
-subject alternative names and ignores the common name entirely, so a certificate
-naming the host only in its subject is rejected by every client:
+1. creates the `llmgw` system user, `/etc/llmgw` and `/var/lib/llmgw`
+2. creates the cluster's certificate authority in `/etc/llmgw/pki`
+3. issues the control plane's certificate for this machine's hostname and
+   every address it has, and copies `ca.pem` beside it
+4. writes `/etc/llmgw/server.yaml`: mutual TLS, authentication, default limits
+   and a price, and a control plane with an empty catalog
+5. creates the store, the `default` project, and your account, already approved
+   and promoted to administrator — the password is generated and **printed
+   once**
+6. installs the systemd unit, starts it, and waits until `/health` answers
+
+Add `--postgres` to keep accounts and keys in PostgreSQL rather than SQLite:
+init installs it and sets it up, and on a machine already running on SQLite it
+moves everything across. See [PostgreSQL](#postgresql-when-sqlite-is-no-longer-the-right-shape).
+
+Every step looks before it acts. Running it again finishes an install that
+stopped halfway and changes nothing on one that did not; it never overwrites
+`server.yaml`, the authority, or an existing account's password.
+
+**The addresses in the certificate matter.** Agents check that the address
+they dial is named in it, and the certificate names only what this machine
+could see of itself. If nodes will reach it by another name — a DNS alias, a
+NAT address, a floating IP — give it:
 
 ```
-sudo llmgw ctl cert issue-server llmgw-ctl \
-  --host 10.0.0.140 --host llmgw-ctl.internal \
-  --dir /etc/llmgw/pki --out /etc/llmgw
+sudo llmgw server init --host llmgw-ctl.internal --host 203.0.113.10
 ```
 
+Run that at any time: the certificate is reissued with the new names added to
+the old ones, and the service restarted.
+
+**`ca-key.pem` signs every node's identity.** `init` leaves it in
+`/etc/llmgw/pki`, because onboarding a node needs it and the control plane is
+where most people run onboarding from. Back it up; there is no recovering it.
+If this machine is exposed, move the directory elsewhere once the nodes are in
+and pass `--pki` to onboarding.
+
 This covers the fleet-facing port only. The client-facing API is public and
-belongs behind an ordinary publicly trusted certificate, usually terminated by a
-reverse proxy in front of port 8080.

-## 4. The mirror
+### The configuration
+
+`/etc/llmgw/server.yaml` is yours from here on. Three things in it are worth
+knowing before you edit it:
+
+- `admin_listen` is on loopback on purpose. It serves pprof, which can dump the
+  process heap, and API keys sit in that heap in plaintext. To see the dashboard
+  from elsewhere use `/admin` on the client port — do not move this listener.
+- `default_rpm`, `default_tpm` and `default_price` are what make limits and
+  budgets mean anything. Without a price every request costs zero and a budget
+  never binds; without the defaults, a project created without limits is
+  metered by nothing at all.
+- `control.enabled: true` is what makes this a control plane while its catalog
+  is empty. Without it, a file with no models is refused as having nothing to
+  serve.
+
+Every key is in [reference.md](reference.md).
+
+### Keeping the authority off the control plane
+
+Create it on another machine, issue the control plane's certificate there, and
+bring only the results:
+
+```
+# on the authority's machine
+llmgw ctl cert init-ca --dir /etc/llmgw/pki
+llmgw ctl cert issue-server llmgw-ctl --host 10.0.0.140 --host llmgw-ctl.internal \
+  --dir /etc/llmgw/pki --out ./ctl
+
+# copy ca.pem, ctl/server.pem and ctl/server-key.pem into /etc/llmgw on the
+# control plane, then there:
+sudo llmgw server init --admin you@example.com
+```
+
+`init` finds certificates in `/etc/llmgw` and no authority beside them, and
+keeps them as they are. Adding an address later is then done where the
+authority is; `init --host` says so rather than minting a second authority no
+node trusts.
