A model with replicas on a card and on CPUs answered at either speed with no
way to tell which. The picker names where each model runs, each reply names
the hardware that served it, and every answer carries x-llmgw-hardware.

A reply streams as text as before; once it ends, the server renders it
with the model card's rules - raw HTML dropped, dangerous links emptied,
images as links - and the page places that. Headings, lists, tables and
code blocks read as they were written.
Maths outside code is set aside before the markdown, so its underscores
and asterisks are not taken for emphasis, and marked for the page to
typeset. KaTeX no longer searches the reply for delimiters, which took
"$5 and $10" for a formula. A reply that cannot be rendered stays
plain text, with the old search.

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.

Reported as the model not completing a request and stopping. It did
complete — it ran out of room. The chat page caps a turn at max_tokens and
then never looked at finish_reason, so a reply that hit the cap ended
mid-word and looked exactly like one that was finished.
The silence was the real defect. A reader has no way to tell "the model had
nothing more to say" from "the page stopped it", and the only clue is that
the last sentence ends abruptly.
512 was also too low. It was chosen when every model here was a 0.5B
answering in a paragraph; it is about a screenful of code, so a coding
model gets cut off inside the first function it writes. 2048 now, which is
still a bound — the reason for having one has not changed.
The notice is appended beside the reply, never into it: that element holds
model output placed with textContent, and building markup in the same node
is how the careful handling everywhere else gets undone.

big-model runs on the sim engine, whose whole vocabulary is the Greek
alphabet, cycled at a fixed rate until max_tokens. That is what it is for:
with no H100s it is the only thing exercising the TP8 two-node path, the
fabric invariant and rebuild-after-node-loss. The output is the point.
What was wrong is that nothing said so. /v1/models returned it with
owned_by "llmgw", identical to the real model, and the chat picker sorted
purely by name — so "big-model" led the list, was preselected by the
browser, and anyone who typed a question and pressed Send got Greek
letters back with no explanation. Reported as the model spitting out crap,
which is a fair reading of what it looks like from outside.
Simulated is derived from the profiles rather than configured: an operator
who adds a sim profile and forgets a flag would be shipping placeholder
text under a real model's name. A model counts as simulated only when
every profile is, because one real profile means the request can still
come back as inference.
The marker on /v1/models is owned_by "llmgw-sim", which is already what
the sim engine calls itself on its own /v1/models — the gateway was
flattening a distinction that existed one layer down.

Replies are plain text, so a model asked about an integral answers with
\int_0^1 x^2 dx and the reader gets the source.
KaTeX is vendored into the binary rather than loaded from a CDN. This gateway
makes no outbound requests of its own and is expected to run where it could
not make one; a chat page that silently loses its maths on an air-gapped
cluster would be worse than one that never had it. 600 KB of JS, CSS and WOFF2
fonts, which the stripped binary absorbs without changing its rounded size.
The ordering is the safety argument, and there is a test for it rather than a
comment alone. The reply is put in place with textContent exactly as before,
and only then walked for maths: renderMathInElement replaces the spans it
recognises, so nothing the model wrote is ever parsed as HTML and the markup
that appears is KaTeX's. trust stays false — KaTeX's default, and what keeps
\href and \includegraphics out of a reply — and throwOnError is off so one
malformed expression does not take the rest with it.
Rendered once the reply is complete. Typesetting each chunk would try to set
half an expression on every token and flicker through the whole answer.
The static handler now serves a small embedded asset tree rather than one
file, so it moved to its own embed: a file server over the tree that also
carries the templates would serve those too. Directory listings are refused —
nothing links to one, so the only requests are from somebody looking around.
