init --patroni user@host ... installs PostgreSQL, Patroni and etcd on the
given machines over ssh, with this one as the third etcd vote, makes the role
and database, and moves the store in use into the cluster. Each step checks
first, so it changes nothing on a cluster that is up. For a store of several
hosts the control plane publishes each member's role, state and lag from
Patroni, a stopped member as missing, prints it in ctl status, and alerts on
it. Making an administrator on PostgreSQL sent a bool to an integer column;
it sends an integer now.

A taken address on PostgreSQL fell through to a generic error, because
the store looked for SQLite's "UNIQUE". It checks code 23505 too. The
done page tells someone whose address had an account to sign in or ask
for a reset, without saying which case it was; other failures give a
logged reference.

A person was in exactly one project, chosen at approval, and could not
use the gateway before that. People belong to several teams and to
none, so:
- memberships: a person is a member of any number of organizations,
teams and projects, or of none; a member of a team or organization
may use every project in it. users join/leave, and the people page
adds and takes out from either side. Approval no longer needs a
project.
- personal keys: a key may have an owner and no project. /profile asks
what a new key spends against; keys create --for does the same.
auth.personal sets default limits for personal use or turns it off.
- limits for people: --scope user holds a person across every key,
project and the chat page; --per-member on an org, team or project
gives each member their own share there. Resolution folds the tree,
each per-member limit for the key's owner, and the owner's own, each
in its own pool; the quotas page shows and sets both.
- the chat page asks what to spend against and checks it per message.
- usage records who spent it, so a person's budget survives a restart,
personal use and chat included; restore no longer drops rows with no
project.
Leaving a project revokes the keys made there unless another membership
still reaches it. A personal key keeps no threads or notes, which are
per project, and is refused rather than dropped into the anonymous pool.
Migration 0010 turns each person's project into a membership, adds
usage.user_id and backfills it, and makes api_keys.project_id nullable.
SQLite cannot drop NOT NULL, so the table is rebuilt; that needs foreign
keys off, which only works outside a transaction, so migrations marked
for it run on one connection with foreign_key_check before commit.
Tested on a populated SQLite store with claims, and on a copy of the
cluster's PostgreSQL store: 5 people became members, 17 keys and 3
claims intact, 145 of 577 usage rows and all 69 chat rows attributed.
The PostgreSQL store tests, including new membership cases, pass on 16.
users move is gone; join and leave replace it.

Nothing in the tree could be renamed, moved or removed, and an approved
person stayed in the project they were first put in — from the web or
the CLI. Now:
- /admin/users is the 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,
plus a search over every account. Forms post and get the page back,
so it works with no script; htmx 2.0.11 (0BSD, embedded, checked
against npm's integrity hash) swaps only the changed part, keeping
open projects open.
- llmgw org tree/add/rename/move/remove, users move/delete, and
keys list --all.
- Projects, teams and organizations are named by id, path
(Acme/platform/gateway) or unique name; users by id or email. With a
single project --project can be left out, instead of defaulting to
"default", which a tree built from the web does not have.
Moving a person moves the keys they made; operator keys stay with the
project. Only empty things are removed, and never a project that had a
key, since usage history refers to it.
Also: keys init no longer reparents an existing team or project;
reinstating an account with no project is refused (a rejected signup
used to come back active and fail at its first key); rejecting a
signup removes it; keys limits --budget takes whole units like the
quotas page.
Checked in headless Chrome: a move from an open project updates the
page in place, keeps the project open, and the search still filters.

Two things that were only ever confusing, and one of them stopped a command
working on the cluster.
The store type was named SQLite and kept the name when PostgreSQL was added, so
OpenPostgres returned a *SQLite and all seventy-odd methods on the production
store were spelled after the database it was not running on. Nothing broke;
people did. Earlier today I added three methods to *SQLite for a table that on
this cluster only ever lives in PostgreSQL, and the name did not once look
wrong. It is a field, which is all it ever was.
`llmgw users` and `llmgw keys` defaulted --store to a SQLite path. On a
deployment whose store is PostgreSQL every one of them failed with "unable to
open database file" while the right answer sat in auth.store in the config file
beside them; the conclusion an operator draws is that the tool is broken, and
they are not far off. They now ask the server's own configuration before
falling back, and the error names which of the three sources chose the address
— the failure was never the path, it was which one picked it.
The single-machine default still applies last, so a deployment with no config
file keeps working with no flags.

So someone can try a model without setting up a client, and — more often —
tell whether a problem is the gateway or their code.
The page carries a session, and the server turns that into the identity an API
key would have produced, resolved from the person's project. The request then
goes down the ordinary path by being handed to the same handler /v1 uses:
admission, model allowlist, rate limits, budget, accounting. There is exactly
one request path, so there is no second place for its rules to drift — and
without that, a playground is a hole in every limit the rest of the gateway
enforces. The allowlist test posts a forbidden model and expects 403 for that
reason.
The body is rebuilt rather than forwarded, so the page cannot set fields it has
no business setting: a stream:false that would hang the reader, a max_tokens
large enough to occupy a replica for an hour. One turn is capped at 512 tokens.
The picker offers what is actually served and allowed, not what is catalogued,
because offering a model with no replica produces a 503 the reader cannot
interpret.
Inline vanilla JavaScript, for the same reason the charts are hand-drawn SVG.
It streams, because on CPU inference ten seconds is normal and a chat that
hangs and then dumps a paragraph feels broken. Replies are written with
textContent throughout: model output and user input have no business being
parsed as markup. Its POSTs carry the CSRF token in a header, which a
cross-site form cannot set at all.

Two things the dashboard was missing: it could not act, and it was a column of
numbers.
Account administration moves to /admin/users — approving into a project,
suspending, reinstating. That is the work an operator does constantly and it
should not need a terminal. Three things stay on the CLI, and the line is not
arbitrary: promoting someone to admin, resetting a password, and issuing a key
on another person's behalf each turn a stolen admin session into more than it
was — permanent access, or somebody else's account. Approving and suspending
do not. Suspending signs the account out everywhere, or suspension is advisory
until the session happens to expire, and an admin cannot suspend themselves,
which is not a thing an interface should let you do by misclicking.
The charts are inline SVG generated in Go. A charting library would mean a
JavaScript toolchain in CI and a megabyte of bundle for what is a list of
rectangles, and the single-binary goal rules that out. Hourly over a day: fine
enough to show a working day, coarse enough that one slow minute is not an
incident. Empty hours are filled in, because a chart with hours missing where
nothing happened reads as a chart with hours missing from the data.
The SVG is marked as trusted HTML, so everything that reaches it is either a
number this package computed or escaped explicitly, and a bar's colour can only
be one of four names — a colour that could be anything is a way to write CSS
into every page the chart appears on. There are tests for both.

Reaching it meant an SSH tunnel, because the page lived on the admin listener
and that listener is bound to loopback. Opening the port was never the way to
fix that: it also serves pprof, and pprof can dump the process heap, where
every API key sits in plaintext. Exposing the port would have been exposing
the key store.
So the page moves rather than the port. The same dashboard is now mounted at
/admin on the client-facing port, behind the session and CSRF machinery that
already guards /profile, gated on a flag on the account. The admin listener
keeps pprof and metrics and stays on loopback.
One bit, not a role system: it grants looking. Everything that changes the
cluster or issues a credential stays on the CLI, where it needs a shell rather
than a session — which keeps the worst case of a stolen admin cookie to "saw
the cluster" rather than "drained your fleet".
Someone without the flag gets 404, not 403. A 403 confirms the page is there
and that admin accounts exist here, which is free reconnaissance; 404 is what
every other unknown path returns. The profile page does not show a link to a
door the visitor cannot open.

The account system shipped without either, which made the first forgotten
password an unanswerable support request.
Changing it requires the current one. A session is what an attacker gets from
a borrowed laptop or a stolen cookie; the password is what they do not have,
and without the check the first thing they would do is take the account.
Every session is closed, including the browser doing the changing — leaving
the others open would mean a password change does nothing about the reason
someone is changing it. A new session is then opened for the browser in front
of us, so the person who just proved their password is not thrown back to the
sign-in page. That response also carries a new CSRF cookie, so the forms it
renders take the new token rather than the one the request arrived with; there
is a test that posts a form from that exact page.
Guessing the current password is bounded the same way sign-in is, because
someone holding a stolen session should not get unlimited attempts at the
password that would let them keep it.
There is no self-service reset: this gateway sends no email, and a reset link
with nowhere to send it is not a reset. `llmgw users reset-password` is the
operator's answer, and it closes their sessions too — if someone lost their
password, the reason might be that somebody else has it.

Every key needed an operator with a shell. This adds the login system that
made that necessary, which is the thing I argued against building until it was
asked for — so it is built as if it will be attacked, because a public login
form is.
Signing up produces an account that can do nothing. Approval is what makes it
work and stays on the CLI: having a shell on the control plane is what makes
someone an administrator, and that is a smaller thing to get right than roles
and an admin UI that mints credentials.
The details that matter:
Passwords are argon2id, where a slow hash is correct — the input is chosen by
a human and has a dictionary, which is the opposite of an API key. Both kinds
of authentication now live in this codebase and they are in separate packages
so neither set of assumptions leaks into the other. Length is the only rule:
composition rules push people towards Password1! and cost more entropy than
they buy.
Signup never says whether an address already has an account, and sign-in
answers the same way for a wrong password and a missing account — verifying
against a dummy hash when there is no user, so a stopwatch cannot enumerate
accounts. Account state is checked after the password, not before, so guessing
an address reveals nothing about it. Guessing is bounded per address rather
than per IP: an attacker has many addresses to come from and one to guess
against, and limiting by IP locks out an office behind one NAT.
Sessions are server-side, so signing out and suspending take effect
immediately rather than whenever a token expires; suspension is checked in the
same query that resolves the session, because a second round trip is a check
somebody eventually forgets. Every state-changing form carries a CSRF token
verified against a hash in the session — a cookie authenticates the browser,
not the page that asked.
Key ownership is enforced in the UPDATE rather than by reading first, so a
guessed key id from another account changes nothing.
