Engine trtllm runs trtllm-serve on one node, through a launcher of
llmgw's that demands the replica's key and turns on the Prometheus
endpoint its queue and cache gauges are read from; the router reads it
at /prometheus/metrics. Brought by the operator (engines.trtllm.python),
not installed; checked by ctl engine-check trtllm. Written against the
documented CLI, server and metrics and tested with stand-ins: not yet
run on a datacenter GPU.
mirror import-ollama copies a model's GGUF, and a vision model's
projector, from Ollama's directory into the mirror, checked against the
digest Ollama named each blob by; mirror import does the same for any
local file. The console's Mirror view imports from Ollama with I.

The manual the binary carries, rendered on the client port: a sidebar of
the documents in the console's reading order (now one list, llmgw.Manual,
for both), heading anchors, links between documents kept in the portal and
links to files outside the binary sent to the repository, no script.
Public by default; landing.docs_sign_in sends visitors to sign in first.
docs/clients.md shows the official OpenAI and Anthropic SDKs against
llmgw in Python, TypeScript, Go and curl, with llmgw's headers; the
portal's index, the landing page and the account page link to it.

A new internal/clientip says who sent a request and how: the connection's
address, scheme and Host, or through a configured proxy what it forwarded.
The base URL in pages and setup scripts, isHTTPS for cookies, and the
per-address limits of auth and the sign-in forms use it. /setup scripts are
no-store.

A wrong password from anywhere counted against the address, so ten locked
its owner out. Attempts are now counted per address and client, with a
looser bound per address alone. The sign-in form carries a token matched
by a cookie (login CSRF). POST /login and /signup are rationed per client
address, a hash waits at most ten seconds for a turn, and server init
writes signup_open: false.

Percentiles are read from the histograms kept with the usage sums and shown
per group on the usage tab and in the people page's panels. Requests refused
by a limit are recorded as 429s against their owner, free of charge, so a team
hitting its limits shows as such. Usage can be grouped by model.

An organization's members, limits and use are a panel of the people page,
where they can also be changed, so the administrator's menu loses its
Organizations entry and /org redirects there. Managers keep /org.

A model with replicas on a card and on CPUs answered at either speed with no

Every minute the agent reads nvidia-smi's full report, its NVLink error
counters and the kernel's XID lines. They are published per card,
shown on the node page and the GPU map, charted in Grafana, and five
alerts watch them.

The cluster page draws every card coloured by utilisation, memory or
temperature, and lists replicas whose every card is under 5% busy.
llmgw_gpu_assigned says which replica, model and owner hold each card.

They were read once, at agent start, and published unchanged since.
Each sample now carries utilisation, memory and bandwidth in use, the SM
clock and uncorrected ECC errors. The node page charts each card, the
cluster page the fleet by class, Grafana has a GPU row, and three GPU
alerts are added.

Each engine has a list of builds, best first, from what its project
publishes and how each was compiled: llama.cpp CUDA 13.3, CUDA 12.8
(driver 570 for the GPUs it ships as PTX), then Vulkan, never the CPU
build on an NVIDIA node; vLLM CUDA 13, then CUDA 12.9, and for GPUs
older than every build of the version asked for, the newest built for
them (V100: 0.19.1). The node takes the first its hardware meets and
that installs and computes on the GPU, moving on when one does not, and
reports the version it runs. GPU processes are read from nvidia-smi's
full report, so Vulkan engines count as on their GPU.
Refs #2.

A node that cannot run the CUDA 13 build installs the same version's
CUDA 12.9 build from vLLM's GitHub release, with PyTorch's cu129 torch;
the install computes on the GPU before it counts. The build can be
chosen per node — auto, cu13, cu129, none — on the cluster page, with
ctl engine-build, or over the admin API; the control plane keeps the
choice and tells the node at once.

The explorer fetches a safetensors set with its config and tokenizer;
the mirror gives out a version's manifest only once nothing is
downloading and every shard its index names is there, with each file's
sha256, which nodes check; mirror add takes several URLs; a repository
page is refused as a source.

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.

engine_overrides give nodes picked by GPU class, id or labels their own
engine versions; node add --disable-engine keeps one off a node; what
vLLM cannot do on a node is a warning rather than a refused node; the
CUDA requirement follows the version; a hand-named binary is no longer
replaced by an installed one.

The form offered no placement and named every GGUF profile cpu. It now
lists the fleet's GPU classes (the freest chosen) and the CPU, a GPU
count and parallel requests, names the profile from the placement, shows
what the model will run as, and refuses the CPU while GPUs are free
unless that is ticked.

An adapters view in the explorer, filtered by the model a held model was
made from; GGUF files told apart as adapter or model by their first bytes;
held adapter files marked; and a model's card attaches and detaches held
adapters of its architecture, refusing models and mismatched architectures.

A catalog model with external {url, model, api_key_file} and no profiles
is published as an endpoint by the control plane, the key read from its
file each time; the router rewrites the request's model to the provider's
name and sends its key. It is never scraped nor stale, and nothing is
placed for it. Named in fallbacks, it serves when the cluster has no room.

The quotas page gains a capacity section over the same API methods the CLI
uses; a model's card sets its class, owner, memory and cores, applying only
what changed. Headroom counts the replicas a model could get by preempting
what its class outranks, and the card and ctl model target use it.

Every agent samples, at most every ten seconds: nvidia-smi's temperature,
HBM temperature, power draw, enforced limit and throttle reasons per GPU;
hwmon's CPU package and board inlet temperatures; and CPU package power
from RAPL's energy counters. Sent with heartbeats, published as metrics
and shown on the node page; unmeasured sensors are absent, never zero.
Observe-only, step 0 of docs/facility-aware-placement.md, which now
describes the agent source and what these readings can and cannot say.

A model's class (critical, standard, opportunistic; unset follows its
scaling) decides what may be stopped to make room for it: a lower class
for a higher, and within a class only what another grew into under load,
for a model below its minimum. Victims are tried on a copy of the
inventory and stopped only if they make the room. Preempted replicas are
drained with a short grace and their model is held back until the room is
used. ctl model resources and class move under ctl model.

A profile's cpu_cores is reserved out of its node's CPUs by placement, as
memory is, and becomes the engine's thread count. Agents report their CPU
count in registration and heartbeats. New CPU models must declare memory;
model views show reserved against measured memory with warnings, and
ctl model resources sets both for a stored model.

The Held tab's model name opens a card: each replica with its node, state,
age, CPU and memory, the room for more found by dry-running the scheduler
on a copy of the inventory, and a form for the always-running and
under-load replica counts. An always-running count placement cannot meet
is refused with the reason. Headroom is also on the admin API.

One long page made every visit wait on Hugging Face for a list it might not

Adding a model took four steps and a YAML file — plan it, fetch it into the
mirror, write its catalog entry with a memory figure somebody estimated,
scale it — and whether it would load was found out at the end.
`llmgw ctl model serve OWNER/REPO` does it as one job in the control plane,
where the registry, the mirror, the catalog and the fleet already are:
- the registry: the GGUF file set matching --quant (Q4_K_M by default) or
--file, leaving out vision projectors and importance matrices, and naming
what the repository does have when nothing matches; gated repositories are
refused;
- the mirror: fetched at the repository's revision, with progress, and each
file's sha256 compared with what the registry published — the mirror is
the one place a corrupted download is caught once rather than loaded on
every node;
- the check: whether the nodes' llama.cpp loads the architecture, and the
memory it needs from its own header;
- the catalog, then a wait for a replica that stops early, with the reason,
when the model is parked or fits on no node;
- a smoke test: one short request to the replica, with its engine key, and
the answer and tokens per second.
ctl starts the job and prints each step as it changes; a download of hours
does not depend on the terminal. --on-demand adds the model without starting
a replica. Jobs are kept in memory until the control plane restarts.
The catalog name a repository suggests moved into the registry package, so
the mirror page and this agree on it.

The serve form asked for weights plus half again plus two gigabytes. That
ignores the one thing that varies most: the KV cache. At the same 16k pool,
the models on the live mirror need from 0.44 GB of cache (Qwen2.5-1.5B, two
KV heads) to 5.25 GB (Gemma-2-9B, 256-wide heads) — so the flat guess
overcounted the small models, which on 7 GB nodes means refusing placements
that fit, and undercounted the ones with wide or many KV heads, which means
an engine killed for memory.
The GGUF header already carries the shape. The reader now also takes each
architecture's block_count, head counts, embedding length and key/value
lengths, reading past general.* until the tokenizer — and a header whose
tokenizer comes first and runs past the fetched bytes still returns what it
has rather than failing. The estimate is weights, plus the f16 KV cache for
the context pool (llama.cpp's --ctx-size, which --parallel divides rather
than multiplies), plus a gigabyte and five percent for the engine. It reuses
the header the servability check already fetched, and the form says what it
is made of. Checked against all twelve GGUF models on the live mirror, whose
shapes read back as their published architectures.

Checked on the live cluster: from any node, the mirror's management API on
:8082 answered — list, fetch, delete — with no credentials. Unset
--api-allow meant anyone. It now means this machine only; the control plane
is let in with --api-allow, which `server init` already wrote for the
mirrors it sets up, or by mutual TLS.
A fetch went to whatever URL it was given, and the file server on :8081
then handed the result to anyone: "fetch http://169.254.169.254/..." read a
cloud's instance metadata through the mirror, and a URL on the LAN read
whatever answered there. Downloads started through the API now go to http
and https only, and are refused at dial time — after resolution, on every
redirect — when the address is loopback, private, link-local, CGNAT or
multicast. --allow-private-sources lets them through for a mirror that
really does copy from a server on its own network. `llmgw mirror add`, run
by someone on the mirror itself, is unchanged.
