-What is left, most needed first. The detail is in the item each names.
-
-**Now: what goes wrong where it is installed.**
-1. ~~**J8**~~: done 2026-10-20. `ctl guard judge check`, and init times the judge. Left of **J3**: its load test
-   against judges on the control plane, which was stopped half way. Judges on a 4-core node of their own refused
-   0/60 at 2 at once, 13/60 at 4 and 42/60 at 10.
-2. ~~**I2 P2**~~: done 2026-10-20: the guardrails both ways, a rate per caller and server, a breaker. A portal page
-   for the servers is left, with P3 (stdio, per-person OAuth).
-3. **K**: fixes from the fabric test the operator runs with docs/large-models.md.

-5. **J4**: the model mirror on more than one machine. Code done 2026-10-29: mirrors kept in step (`mirror serve
-   --peer`, removals carried), `mirror.peers` and failover in the control plane, nodes given the file on a mirror that
-   answers, `mirror add-peer` and the setup's second mirror. Tried 2026-10-29 on two VMs:
-   - `add-peer` set the second up over ssh;
-   - a file came across in ~30 s, checksum matching;
-   - a version added on the second while the first was off reached the first when it came back;
-   - one removed on the first while the second was off was removed there when it came back, not copied back.

-
-### H9. Small things learned on the PoC (2026-10-14)
-- Done: `albedo_match` on sf3d (its delighting made dark objects light);
-  `on_demand.evict_after_idle` / `min_lifetime` as live settings; an
-  upgrade that leaves nodes behind says which; `ctl model serve` serves an
-  embedding model for embedding; refreshes wait while a form is filled in.
-- Done 2026-10-15: llmgw's `/mcp` with picture, 3D, VLM and workflow tools,
-  so a client needs no server of its own (asked by the game team); the
-  shared ComfyUI replica (H3's placement side).
-- Done 2026-10-16 (v0.14.6, v0.14.7): setup lists every part with what it
-  is and its settings; three machines each run the control plane, with a
-  floating address (VRRP id from the address); a lost store primary costs no
-  request (3 s connect per member, keepalive and TCP_USER_TIMEOUT, Patroni
-  ttl 20, a standby leaves the lease alone a round after the store returns);
-  a new leader waits for its judge within the budget; a judge is asked again
-  on another machine at half its budget; init sizes the judge (2 GB, no
-  prompt cache, two cores, one judge on up to four cores on one machine).
-
-## I. What other gateways do that llmgw does not (written 2026-10-16)
-
-From a comparison with Bifrost (maximhq/bifrost, Apache 2.0, Go), with
-LiteLLM and Portkey in mind. Bifrost routes to 23+ cloud providers and runs
-no model; llmgw runs the models, so most of Bifrost is either in llmgw
-already (keys, budgets, fallbacks, guardrails, tracing, SSO, HA — the last
-three paid in Bifrost) or does not apply. These four are worth taking for
-a site that runs its own models. Left until a customer asks: native
-Azure/Anthropic/Bedrock/Vertex adapters, request hooks a customer plugs in,
-routing by what a request holds. Not taken: a realtime (WebSocket audio)
-API, prompt management, an `npx` install.
-
-### I1. Answers to similar questions, not only the same one (M) — done 2026-10-25
-`keys cache --similar`, `router.cache.embedding_model`, `internal/router/similar.go`. Changed
-from the plan: the vectors are in the gateway's memory beside the exact answers, not a pgvector
-table. The exact cache keeps answer text out of the store on purpose (data.md), and a table of
-answers would undo that; it also works on SQLite. The usage row marks a similar hit as a hit
-(no column of its own). Open: the 40-rewordings and eval-suite runs on the PoC.
-The original item follows.
-The answer cache (`internal/router/cache.go`, C17) answers a request whose
-body is the same byte for byte. A help desk asked "how do I reset my
-password" in forty wordings asks the model forty times.
-- Per project, off by default, beside the exact cache: `llmgw keys cache
-  --project P --similar 0.95` (the cosine similarity a question must reach;
-  higher is stricter). The exact cache is asked first.
-- The question embedded by a model the operator names
-  (`router.cache.embedding_model`, an embedding model in the catalog), into a
-  pgvector table per project with the answer, the model and the TTL; the
-  store's halfvec and text index work from F applies. SQLite stores keep the
-  exact cache only.
-- What counts as the question: the last user turn, with the system prompt
-  and the earlier turns hashed and required to match exactly — a similar
-  question in another conversation is not the same question. Tools,
-  `response_format` and the sampling settings also exact.
-- Said: `x-llmgw-cache: similar` with the similarity, and the usage row
-  says so; guardrails judge the request before a hit, as for the exact
-  cache. A project with `no_store` gets neither.
-- Done when: forty rewordings of one question on the PoC cost one model call
-  and 39 lookups, and an eval suite run with the cache on scores within a
-  point of the run with it off.
-
-### I2. MCP gateway: the customer's tool servers behind llmgw (L)
-P1 done 2026-10-20: HTTP servers registered (`ctl mcp`, `/api/v1/mcp/servers`,
-store `mcp_servers`), tools as `server.tool` in `/mcp`, `allowed_tools`
-grants in the tree (deny by default), credentials in the store or by
-reference, the caller named in `X-Llmgw-*` headers, time and size bounds,
-progress passed on, audit (Source `mcp`) and metrics. Left: P2, the
-guardrails both ways, a per-tool rate limit, a breaker, and a portal page;
-P3, stdio servers and per-person OAuth. The "done when" with Claude Code
-against a real server is still to try.
-`/mcp` serves llmgw's own tools. An agent inside a company also wants Jira,
-the file server, a database — each an MCP server, each today configured
-in every client with its own credentials and nobody seeing what was called.
-- Servers registered once, by an administrator: `llmgw ctl mcp add jira
-  --url https://… --header-file /etc/llmgw/secrets/jira` (HTTP transport;
-  stdio servers run on the control plane under their own user, like an
-  engine). Their credentials stay on the control plane, never in a client.
-- `/mcp` lists every server's tools, prefixed by its name (`jira.search`),
-  filtered by what the key may use: an allowlist per org, team, project or
-  key, by server or by tool, in the tenancy tree as model allowlists are.
-- Each call goes to the audit log — who, which tool, the arguments' size,
-  the outcome and how long — and through the guardrails both ways (a tool's
-  answer is prompt input). A per-tool rate limit.
-- Later, if it earns it: Bifrost's "code mode" (the tools as one typed API
-  the model writes code against), which cuts the tokens of a long tool list.
-- Done when: Claude Code given only llmgw's `/mcp` reaches a test MCP server
-  through it, a key without the grant does not see the server's tools, and
-  every call is in `ctl audit`.
-
-### I3. What llmgw adds to a request, measured (S) — done 2026-10-16
-`llmgw ctl bench overhead` (`internal/cli/bench_overhead.go`): an instant
-engine and the gateway in one process, four modes (direct, bare, auth, auth
-and guard patterns) at rising rates. On an Apple M5 the gateway added
-0.05–0.42 ms at p50 and at most 0.49 ms at p99, in the README.
-`TestTheGatewaysOverheadIsMeasured` runs a second of it in CI with no bound
-asserted. Left: the CPU figure is rough with everything in one process; a
-gateway in a process of its own would measure it properly. The original
-item follows.
-
-Bifrost's headline is "11 µs at 5k RPS" (its own figure, and its own pages
-disagree with it). llmgw has none, so any question about its overhead is
-answered with a guess.
-- `llmgw ctl bench --overhead`: the same load through the gateway and straight
-  at a `sim-engine` (`internal/cli/simengine.go`) that answers at once, at
-  rising request rates, with auth, accounting and the guardrails' pattern
-  checks on and off. Reports the added latency at p50/p99 and the gateway's
-  CPU per thousand requests.
-- On the PoC the CPU is oversubscribed (pve1, 28 threads for ~125 vCPUs):
-  report it as a ratio and record the host's load beside it, and repeat on
-  an idle machine before a figure goes into the README.
-- Done when: the README states the overhead, with how it was measured, and
-  CI runs the short version so a change that doubles it is seen.
-
-### I4. Several keys for one outside provider (S) — done 2026-10-17
-`external.api_key_files` (`catalog.ExternalKey`: file, weight), one endpoint
-each in `control.externalEndpoints`, 401 retried on another key and
-`external_key_refused` notified (`router.keyRefused`). With one key a 401 is
-still the client's. `TestAKeyAtItsLimitOrRefusedIsPassedOverForAnother`. The
-original item follows.
-
-An external model has one `api_key_file` (`internal/control/control.go`,
-where external endpoints are made). A provider's limit is per key; one key
-answering 429 makes the whole fallback answer 429.
-- `api_key_files: [a, b, c]`, each with an optional `weight`: one endpoint
-  per key (`external:<model>#<n>`), so the router's scoring, retries and
-  breakers work per key as they already do per replica. A key answering 429
-  or 401 is passed over while its breaker is open; a 401 also notifies
-  (`external_key_refused`).
-- The usage row says which key answered (by its index, never the key).
-- Done when: with two keys and one returning 429, every request is answered
-  by the other, and the console shows the one breaker open.
-
-## J. Found testing HA and single-machine installs (written 2026-10-16)
-
-Three VMs installed as HA from the setup screens, a fourth as a judge node,
-a fifth as a single 4-core, 8 GB machine; machines powered off under load.
-
-### J1. A restart refused for room another restart was giving back (S) — done 2026-10-16
-Not a wait for ever, as first written: on the 4-core VM the judge's restart
-was *refused* ("fits on no node even with this replica stopped") because the
-starter, restarted at the same time to reserve fewer cores, still held its
-old ones. Once refused, nothing tried again, so the judges kept their old
-figures. Two fixes in `internal/control/reconciler`:
-- a restart whose replacement fits once other restarts under way have gone
-  (queued, retiring or draining) waits for them, up to DrainGrace, instead
-  of being refused (`fitsAfterRestarts`, restart.go);
-- a drained replica counts a retiring one that still answers as serving, so
-  one restart after another no longer leaves the first's drained replica,
-  and the room it holds, waiting out its grace (reconciler.go).
-`TestARestartWaitsForRoomAnotherRestartWillGiveBack` is the 4-core case.
-
-### J2. A judge the leader adds is sized as init's is (S)
-When a policy names a judge the catalog lacks, the leader serves it itself
-(`internal/cli/judgekeeper.go` via `knownJudge.serveRequest` in
-`judges_known.go`, through modelserve). That judge reserves 3 GB (the
-weights, an 8192-token KV cache and a fixed gigabyte), no cores, and runs
-with llama.cpp's prompt cache, which grew one to 3.2 GB. init's judge
-(`guardModel` in `internal/cli/serverinit_cluster.go`) reserves 2 GB and
-its cores and runs with `--cache-ram 0`.
-- `modelserve` gives a guard model `--cache-ram 0`, and the keeper's
-  request the same memory and cores rule as `cpuPlan`.
-- Done when: a judge removed from the catalog comes back with the same
-  figures init would have given it.
-
-### J3. HA setup puts the judges on nodes of their own (S)
-Under load on a 4-core control plane that was also a node, 38 of 60
-requests were refused for want of a judgment. With the judges on a node of
-their own (4 cores, 32 GB, two cores each) the same test refused 2.
-- The HA setup offers a judge node or two: machines given like the store's,
-  added as nodes with a label (`llmgw.role: judge`), and the judge's
-  profile selects that label.
-- Done when: the setup installs the judges on the machines given for them,
-  and the load test above refuses no more than it did by hand.
-
-### J4. The model mirror on more than one machine (M)
-In an HA install the mirror stays on the first machine. While it is down,
-models the nodes already have keep serving and new ones wait for it.
-- A second mirror kept in step (each machine of the store, or one more), the
-  control planes and nodes given both, the first that answers used.
-- Done when: with the first machine powered off, a model added then is
-  fetched and served.
-
-### J5. An upgrade corrects an earlier install's judge (S) — done 2026-10-16
-Built in the judge keeper (`internal/cli/judgekeeper.go`, `refit`), on the
-leader: a judge whose entry is exactly what init before v0.14.7 wrote is
-given 2 GB, `--cache-ram 0` and cores by init's rule (`refitCores`: up to
-four for one judge, two each for more), through `modelsvc.SetProfiles`,
-and its ready replicas are restarted (after J1). Its replica count is left
-as it is. One that differs is left alone and said once in the log. The
-original item follows.
-
-v0.14.6 and earlier installed two judges reserving no cores or one, with
-2 or 4 GB and the prompt cache on. On fewer than eight cores every judgment
-missed its 5 s budget and every request was refused. v0.14.7's notes say
-how to fix it by hand (`ctl model resources`, then `ctl restart`).
-- On upgrade, or on `server init` run again, a judge whose profile is still
-  exactly what an earlier init wrote is moved to today's figures and
-  restarted (after J1). One changed by hand is left alone and named.
-- Done when: a v0.14.6 single-machine install upgraded to it judges within
-  budget without anything typed.
-
-### J6. Rate limits per process (note)
-Rate limits are counted in each control plane's memory. A failover starts
-every key's minute afresh. Documented in install.md; worth a shared count in
-the store only if a customer's limits must hold across a failover.
-
-### J7. nginx in front of several control planes (S)
-`deploy/proxy/Caddyfile` sends to whichever control plane answers `/leader`.
-nginx's open-source build has no active health checks, so its `upstream`
-block would send to standbys and to a lost leader alike.
-- nginx.conf: the floating address as its one upstream, and why; or the
-  `max_fails` passive approach with what it costs.
-
-### J8. A judge budget that fits the machine (S)
-A judgment takes 2.3 s on four cores and 4.2 on two, against the 5 s
-default: two cores are close to it, and a busy machine passes it.
-- At install, after the judge is up, time three judgments. If the slowest is
-  more than half the budget, say so in the plan's closing text with the
-  choices (more cores, a GPU judge, a longer `latency_budget`, `fail:
-  open`). The budget itself is not changed without being asked.
-- Done when: an install on a machine too slow for its judge says so before
-  its first refused request.

-## L. Taken from Kong's AI Gateway (written 2026-10-25)
-
-From a look at Kong AI Gateway 3.9–3.16 and 2.x. Kong's open source stops at
-3.9, and only six of its AI plugins are open (proxy, prompt template,
-decorator, regex prompt guard, request and response transformer); the rest
-is Enterprise or Konnect. So nothing of Kong is embedded: the two meet over
-plain OpenAI/Anthropic HTTP, and these are the ideas worth taking. Not taken:
-prompt compression (Kong ships it as a private LLMLingua sidecar, its benefit
-unshown), prompt templates and decorators (no one has asked), Konnect's
-entity model. MCP items are llmgw-80's (I2); they are listed for it.
-
-### L1. Traces in the OpenTelemetry GenAI conventions (S) — done 2026-10-25
-`gen_ai.*` on the `inference` and `upstream` spans (`internal/router/trace.go`):
-operation, request and response model, max_tokens, temperature, top_p, the
-session as conversation id, input/output/cached tokens, the engine as
-provider. Never prompt or answer text (`TestTracesSpeakTheGenAIConventionsAndHoldNoText`).
-Prometheus already counted tokens by direction, cached apart. Left: the MCP
-calls' spans as `gen_ai.tool.*`, once /mcp is traced at all.
-
-### L2. Redacted personal data put back in the answer (S) — done 2026-10-25
-`restore: true` (`guard.Rules.Restore`), `Verdict.Restore`, `internal/router/restore.go`
-ahead of the output filter. The original item follows.
-The guardrails rewrite personal data as `[KIND_n]` (`internal/guard/gate.go`,
-`placeholders`), the same value always the same placeholder. A model that
-answers "Dear [PERSON_1]" leaves it so. Kong's sanitizer restores.
-- Per policy, `restore: true`: the placeholders of one request kept in memory
-  for its life, and swapped back in the answer, streamed too (a placeholder
-  split across two chunks held until it is whole).
-- Only into the answer to the request that held them; never stored, never in
-  usage rows or traces.
-- Done when: "write to Ayşe Yılmaz at ayse@example.com" through an enforce
-  policy reaches the model as placeholders and the client reads the real name
-  and address back.
-
-### L3. A guardrail that is someone else's service (S) — done 2026-10-25
-`guard.Service` (`internal/guard/service.go`), policy `services`, asked
-before the judge on input and once on the whole answer. The original item follows.
-Customers may be required to use one: Azure Content Safety, Lakera, NeMo
-Guardrails, an in-house classifier. Kong's AI Custom Guardrail is a
-templated HTTP call with an expression for "block".
-- A detector kind `http`: URL, headers from secret files, a body template
-  with the text, a JSON path that says blocked and one that says why;
-  timeout and `fail` as the judge's. Checked on input, output or both.
-- Done when: a policy with an `http` detector against a test service blocks
-  what it says to, and a service that does not answer is treated as `fail`
-  says.
-
-### L4. Routing by latency and by cost, and failover by priority (M) — latency done 2026-10-25
-`endpoint.Registry.ObserveTTFT`, `scheduler.Latency()` in `chat`. Failover in tiers is
-what `fallbacks` already does (local, then an outside model when no room). Left:
-routing by cost between several outside providers. The original item follows.
-The scorers (`internal/router/scheduler/scorers.go`) know sessions, queues
-and KV cache. Kong also balances by measured latency, by tokens or cost
-used, and in priority tiers.
-- A `latency` scorer: a moving average of time to first token per endpoint.
-- Fallbacks in tiers: local replicas first, then an outside provider, with
-  the tier said in the usage row.
-- Done when: with two replicas of one model, one on a slower card, `latency`
-  sends most of the traffic to the faster and the slower still gets some.
-
-### L5. Prices by kind and by cache (S–M) — done 2026-10-25
-`cached_per_1k`, charged on the answer's `cached_tokens`. A budget in money was already
-there (`keys limits --budget`). Not done: cache-write and audio/video token prices —
-no engine llmgw runs reports them, and no provider it reaches is billed by them yet.
-The original item follows.
-`catalog` prices are per million input/output tokens and per picture/mesh.
-Kong prices cached reads and cache writes apart, and audio, image and video
-tokens apart, and limits by cost.
-- Price fields for cached input and by modality; the usage row's cost from
-  them; a budget limit in money as well as tokens (`keys limits --cost`).
-- Done when: a request with 90% cached prompt costs what the cached rate says.
-
-### L6. REST APIs as MCP tools (M) — for llmgw-80, beside I2
-Kong turns OpenAPI operations into MCP tools. A company with an internal
-REST API and no MCP server could offer it to agents through `/mcp`:
-`llmgw ctl mcp add hr --openapi https://hr.internal/openapi.json`, each
-operation a tool, under the same grants, audit, guardrails and rate as I2.
-
-### L7. MCP sign-in by the MCP spec (M) — for llmgw-80, part of I2 P3
-Kong's MCP OAuth2: llmgw's `/mcp` as an OAuth 2.1 resource server (protected
-resource metadata, tokens checked by JWKS against the company's identity
-provider), and a token exchanged for a short-lived one per upstream server
-rather than one long-lived secret.
-
-### L8. A2A (S, when asked)
-Agent-to-agent traffic through the gateway: agent cards' URLs rewritten to
-llmgw's, calls audited and traced. The standard is young; wait for a
-customer.
-
-### L9. llmgw behind Kong, written down (S) — done 2026-10-25
-docs/kong.md, tried with kong:3.9: plain route and ai-proxy, keys passed on;
-Kong 3.9 counts no completion tokens of a stream. The original item follows.
-A customer that already runs Kong puts llmgw behind it: `ai-proxy` with
-`provider: openai` and `upstream_url` at llmgw (3.9, open source), or a plain
-route. A page in docs/ with the configuration, tried against Kong 3.9 in a
-container, and what Kong's token accounting sees.
-
-## M. Models from Hugging Face we can trust (written 2026-10-25)
-
-The user asked how we know a model fetched from Hugging Face is safe. Two
-questions: whether its files can run code on our machines, which we can
-close, and whether the model itself was trained to misbehave, which no scan
-proves — only who published it, an eval before it serves, and the
-guardrails narrow that. What existed: `--trust-remote-code` refused, no
-repository Python fetched, ComfyUI nodes pinned to a commit, engines
-hash-pinned and run as `llmgw-engine`, mirror versions pinned to a commit
-and never overwritten. What did not: everything below.
-
-### M1. Weights in a pickle format refused (S) — done 2026-10-25
-`.bin`, `.pt`, `.pth`, `.ckpt`, `.pkl` run code as they are loaded, which is
-how the malicious models found on Hugging Face work. The node refuses such a
-source, or a mirror set holding one, before fetching anything; a model being
-added or given such a source is refused; vLLM and SGLang downloading a model
-by its id are given `--load-format safetensors`. The explorer hides a repository with neither GGUF nor safetensors
-(under "runs here", ticked by default) and does not offer a repository's
-pickle files. `allow_pickle: true` on a model lets it through, on purpose. On the
-PoC, `triposr` (`hf:stabilityai/TripoSR/model.ckpt`) is the one model that
-needs it.
-
-### M2. Every download pinned and checked against Hugging Face (M)
-- `hf:org/repo/file` follows `main` and is checked by nothing; a bare
-  `org/repo` given to vLLM is downloaded by vLLM, of whatever `main` is.
-  Both: resolve to the commit when the model is added, keep it in the
-  catalog's origin, and fetch that commit only (`--revision` for vLLM).
-- The sha256 Hugging Face publishes for each LFS file compared on every
-  path, and a file that differs removed: `mirror add`, the manager, the
-  node's `hf:` and http sources, mirror set files with no sha recorded.
-- Done when: a file changed on Hugging Face after a model was added is
-  refused by the node with both checksums named.
-
-### M3. Hugging Face's own scan (S)
-Hugging Face scans every file (pickle imports, ClamAV, partners' scanners)
-and marks a file unsafe. Ask for it with the repository listing; refuse an
-unsafe file, show the result on the mirror page and in the catalog's origin.
-The API field has to be confirmed first.
-
-### M4. Publishers we trust, and the rest asked about (S)
-An allow-list of organisations in the cluster's settings (Qwen, meta-llama,
-mistralai, google, microsoft, …). A model from anyone else is added only by
-an admin who says so, and who said it is kept in the origin. The PoC already
-serves four community models whose training nobody here checked.
-
-### M5. Engines without the internet (M)
-The firewall is inbound only, so an engine that was made to run code can
-send what it reads anywhere. With weights from the mirror the engines need
-no egress: an nft output rule for the engine user (allow the mirror, the
-cluster, loopback), systemd hardening of the agent's engines
-(`NoNewPrivileges`, `ProtectSystem`, private /tmp). Agent itself still root.
-
-### M6. An eval before a new model serves (S)
-`eval` and `canary` exist; make a new model from an untrusted publisher
-(M4) serve only after its eval suite passes, so a model trained to answer
-wrongly on a trigger has at least been asked the suite.
-
 ## D. Facts worth knowing before starting
 
-- Admin API: `127.0.0.1:9090`, behind the token in
-  `/var/lib/llmgw/admin-token` (A5), `ctlClient` in `internal/cli/ctl.go`.
+- Admin API: `127.0.0.1:9090`, no auth, `ctlClient` in `internal/cli/ctl.go`.
   Metrics on `:9091` with `/prometheus/targets` beside them.
 - Store: `internal/store`, migrations under `internal/store/migrations/{sqlite,postgres}`;
   the PoC runs PostgreSQL under Patroni.

-## v0.15.2 — 2026-10-29
-
-A served model moved to more cards, or fewer, while it is served.
-
-**Upgrading.**
-- No migrations, and nothing changes until the command is used. The control
-  planes carry it; the nodes need nothing new.
+## Unreleased
 
 ### Added
 
-- **A served model moved to more cards, or fewer.** `llmgw ctl model gpus
-  MODEL N [--profile P] [--in-place]`, `POST /api/v1/models/{name}/gpus`, and
-  GPUs… in the console's model menu. How many cards of one node each replica
-  uses: tensor parallel for vLLM, SGLang and TensorRT-LLM, checked against
-  the model's KV heads, and the layers split for llama.cpp. Refused for a
-  count no node has, or whose cards would not hold the model and its
-  context, with the figures; its replicas are then started again on it, one
-  by one, beside the old — or, with `--in-place` when there is no room
-  beside them, each stopped first.
-
-## v0.15.1 — 2026-10-29
-
-A 125B model on one card, a second mirror, and weights that run code
-refused. Strata runs as an engine: a mixture-of-experts model with its
-experts in RAM, served from one 24 GB card. A second model mirror keeps in
-step with the first, so an HA install has no single machine left. Pickled
-weights are refused unless a model says otherwise. A served model's context
-can be changed in place. The explorer says how fast a model would answer
-here before it is fetched, and a card in the wrong PCIe slot is said so.
-
-**Upgrading.**
-- No migrations. Upgrade the control planes before the nodes, for the
-  pickle refusal below.
-- A model whose weights are in a pickle format (`.bin`, `.pt`, `.pth`,
-  `.ckpt`, `.pkl`) stops being placed: its node refuses the source. Give it
-  its safetensors or GGUF, or add it again with `allow_pickle: true`
-  (`llmgw ctl model add -f`) if its files were checked. Look at the
-  models' sources before upgrading the nodes: one ending in
-  `.ckpt` or `.bin`, or a mirror version holding `pytorch_model.bin`. Upgrade the control planes first: a node on
-  this version refuses those weights until its control plane can say
-  `allow_pickle`.
-- Strata is opt-in: nothing installs it until `engines` or an
-  `engine_overrides` entry names a version (`0.2.7`).
-
-### Added
-
-- **Strata as an engine: a 125B model of experts on one card.** Strata
-  (github.com/Niko1221/Strata) keeps a model's experts in RAM and the ones
-  used most in VRAM. On an RTX 6000 24 GB with 251 GB of RAM it serves
-  Qwen3.8-Flash-Next 125B (IQ2_XS) at 70–87 tokens a second to one client;
-  more clients share about that, its slots buying fairness rather than
-  throughput on one card. It runs a few families only — Qwen3.8-Flash-Next
-  and its variants, Qwen3.6-35B-A3B, DeepSeek V4.1-Flash — each named in a
-  profile's args with `--family` and `--size`
-  (`--family qwen --size IQ2_XS --context 32768`). The source is the
-  directory of the model's GGUF files, or the repository, which Strata then
-  downloads itself, pinned. The agent installs it on an NVIDIA node of
-  x86-64: its source pinned by digest, in a Python environment, and its
-  release's engine checked against the digest GitHub publishes — the CUDA 13
-  build for Turing and newer on driver 580, the CUDA 12.9 build for Pascal
-  to Ada, a V100 included, on driver 575. A replica prepares its model the
-  first time (minutes; its draft layer is a 5 GB download) and loads in
-  about a minute and a half after. One card of one node per replica, for
-  now; not in an offline bundle, its packages coming from PyPI.
-
-- **A served model's context, changed.** `llmgw ctl model context MODEL
-  TOKENS [--slots N]`, `POST /api/v1/models/{name}/context`, and Context
-  length… in the console's model menu. The catalog, the engine's arguments and
-  the memory change together, checked against what the model was trained for
-  and what its cards hold; its replicas are then started again one by one. The
-  models API shows `context_length` and `max_output`.
-
-- **A second model mirror, kept in step.** In a three-machine install the setup screens put one on a database machine
-  (`--second-mirror 1|2`). An install with one mirror gets one with `sudo llmgw mirror add-peer user@host`.
-  - **In step:** each mirror reads the other every thirty seconds. It copies what it lacks, checksum checked, and
-    removes what the other removed, even if it was down at the time (`llmgw mirror serve --peer`).
-  - **Control planes:** they name both (`mirror.peers`) and use whichever answers.
-  - **Nodes:** while one mirror is down, a node is given a model's file on the other.
-
-  This takes away the last single point of an HA install: with the first machine off, models are still added and
-  fetched.
-
-### Fixed
-
-- **An engine that computes in a process of its own group was not its
-  replica's.** A GPU replica read as running on the CPU, and the memory it
-  held on its card as somebody else's, which placement then kept free of
-  other work. A process the replica started, at any remove, is now the
-  replica's. And what a replica computes on, once sent, was never sent
-  again: a wrong reading kept from before an agent's restart stayed wrong.
-  It is sent again when it changes, and read again when a GPU replica was
-  kept as the CPU.
-
-- **VS Code's sign-in lost its place through the sign-in page**, so the
-  prompt to confirm came every time; a link to the same gateway by plain
-  http could take an https setting down to http; and a new build of the
-  extension was not installed over an old one (the command now says
-  `--force`).
-- **The install guide's recordings were not checked for secrets**, only
-  the page; every frame is now.
-- **MCP server fields could not be emptied**, an address could carry a
-  password, the cluster's own server could not be changed from the
-  console, and a grant to a key that does not exist was said done.
-- **A guardrail service two policies named was asked as the first said**,
-  not the stricter; a `null` answer read as safe; and with `restore` the
-  request log kept the answer with the redacted values back in it.
-- **What an engine downloads by a Hugging Face id was not held to the
-  pickle refusal** — an adapter by its id, a TensorRT-LLM model's; a model
-  with either now needs `allow_pickle`.
-- **`server init` run again on a machine already set up was refused its
-  memory**, as on an 8 GB install fixing its certificate with `--host`, and
-  judges that would not be installed (no mirror) were counted.
-- **Removing an MCP server left its sealed credential in the store**, and
-  replacing a credential under another header kept the old one sent. A
-  server's secrets now go when it no longer reads them.
-- **A cloned repository could point the VS Code extension at another
-  gateway.** `llmgw.gatewayUrl` is a machine setting now, never taken from a
-  workspace.
-- **A node's memory bandwidth could be measured in its cache** on a busy
-  node, and was 0 after a reconnect until the next heartbeat. The buffer is
-  at least eight times the processor's last cache.
-- **A project kept in the cluster could have its questions embedded outside
-  it.** The similar-question cache now asks the embedding model as the
-  question's project would, external fallbacks refused, and skips a model
-  that is itself outside. Its comparing no longer holds the cache's lock,
-  which every project's lookups waited on.
-- **Restored values were left as placeholders in streamed tool calls**, in
-  completions and in reasoning, and a value with a quote in a whole answer's
-  tool-call arguments broke their JSON.
-- **An outside guardrail service read what `redact` had taken out**, and a
-  streamed answer was sent to it twice. The docs now say a service stops a
-  streamed answer only under `stream: buffer_all`.
-- **A replica found slow once could stay unused.** Its time to first token
-  is forgotten after five minutes without an answer, so it is tried again.
-- **Weights that run code got past the refusal in four ways.** A mirror
-  version already on a node was used without being looked at again; a
-  `?query` or `#fragment` on an `hf:` source hid the file's name; `.pt2` was
-  not on the list; and a profile could write `--load_format`,
-  `--trust_remote_code` or an abbreviation such as `--trust-remote`, which
-  vLLM and argparse read as the flag, or give SGLang `--load-format`. All
-  refused now. TripoSR's preset says `allow_pickle`, without which it could
-  not be added, and a shared ComfyUI environment takes its first member's.
-- **A temperature written as a string was refused.** Since the GenAI traces
-  read it, `"temperature": "0.7"` got a 400 before reaching the engine; it
-  is read loosely again, for the trace only.
-- **A reused answer could carry another caller's personal data.** With
-  `restore: true` and the answer cache on, two callers' requests that
-  redacted to the same text shared one answer — with the first caller's
-  address put back in it. Such requests are now never answered from the
-  cache nor kept in it.
-- **Granting a server's tools could take others away; revoking could close
-  a level to every tool.** A level with no tool list sees what the levels
-  above grant; giving it its first list made it see only that list. And a
-  level left with an empty list was closed to every tool, which the screens
-  did not show. Now a first list starts from the nearest list above, taking
-  a server away leaves the rest or goes back to no list, the screens say
-  when a level above keeps granted tools out of reach and which levels are
-  closed, and the console reads and writes the level at once rather than
-  from what it loaded.
-- **Similar questions about different pictures got each other's answer.**
-  A question with a picture, a sound or a file in it is reused only when it
-  is the same request.
-
-### Added
-
-- **A card in the wrong PCIe slot is said so.** Each agent reads how every
-  card is linked — the fastest generation card and slot allow together, and
-  the lanes in use — against the card's own most, from the kernel (the
-  driver's figure is what card and slot allow together); a card on fewer lanes or
-  an older generation is a node warning, with what it carries and what it
-  could, on the dashboard, the console and in `llmgw doctor`.
-- **And on a web page, `/admin/mcp`.** For administrators: the same list,
-  adding a server with its credential sealed, testing it and listing its
-  tools, granting them in the tree beside that level's other grants and
-  limits, revoking, changing, replacing the credential, turning it off,
-  removing; and the line that points an agent at this gateway's `/mcp`.
-  In English and Turkish; every change in the audit log, the secret not.
-- **The company's MCP servers in the console.** A screen of its own: each
-  server with its state, who has its tools, its rate, the names of the
-  credentials it is sent and its address; add one with a bearer token or
-  a header kept sealed, test it and list its tools, grant them to a team,
-  project, organization, person or key beside that level's other grants,
-  revoke, change, replace the credential, turn off, remove.
-- **And on the cards, as this cluster would lay it out.** The explorer's
-  **GPU tok/s** and a repository's files give one reply's speed for each
-  layout the planner offers here — one card, tensor parallel across a
-  node's cards, llama.cpp's layer split, a pipeline across nodes on a
-  fabric — the fastest of them, with the layout in the tooltip. From each
-  card's memory bandwidth by its model name, NVLink or PCIe between a
-  node's cards, and InfiniBand or RoCE between nodes; a cluster of mixed
-  classes is judged class by class. A model of experts reads 1.6 times its
-  active share, as Qwen3-Coder-30B-A3B did on cuda01's RTX 6000 (144
-  tok/s; qwen3-vl-8b Q8: 62).
-- **How fast a model would answer on a CPU, before it is fetched.** Each
-  agent measures how fast its node's memory reads when it starts (`Host`
-  gets `mem_bandwidth_gbs`, the node's view `mem_bandwidth_gbs`); the
-  explorer's **CPU tok/s** column and a repository's GGUF files say about
-  how many tokens a second one reply gets on the fastest node that holds
-  the model — the bandwidth over the bytes a token reads, its active part
-  for a model of experts. Calibrated on the PoC against llama.cpp's own
-  timings: within 15% from 1.5B to 14B.
-- **The explorer lists what this cluster can run.** Judged by the nodes
-  as they are now — every card's memory and compute capability, every
-  node's RAM — through the same planner as serving a model, rather than a
-  size picked from a list. A model too big for any node, in FP8 without a
-  card of 8.9, in MLX, or in neither GGUF nor safetensors, is left out and
-  counted; the page says what it judged by. With cards, safetensors repositories are
-  listed beside GGUF. On a repository's page a file too big for the
-  cluster is shown with what it needs and no Fetch button.
-- **Weights that run code are refused.** Python pickles — `.bin`, `.pt`,
-  `.pth`, `.ckpt` — run whatever they hold when loaded, which is how the
-  malicious models on Hugging Face work. The node refuses such a source,
-  or a mirror version with one in it, before fetching it; adding such a
-  model is refused; vLLM and SGLang downloading a model by its id read its
-  safetensors only; the mirror page marks the file. `allow_pickle: true`
-  on a model lets it through on purpose. The mirror's explorer no longer
-  lists a repository with nothing a node loads (no GGUF, no safetensors)
-  while "runs here" is ticked, and a repository's pickle files are not
-  offered, only counted. BACKLOG M lists what is next:
-  checksums against Hugging Face everywhere, its own scan, trusted
-  publishers, engines without the internet.
-
-## v0.15.0 — 2026-10-25
-
-The company's tools and editors through the gateway, and guardrails that
-can lean on others. Its own MCP servers sit behind llmgw's `/mcp` under the
-guardrails, a rate and a breaker. VS Code gets the gateway's models from an
-extension the gateway serves. A guardrail policy can ask an outside
-service, and can put redacted values back in the answer. Chat goes to the
-replica answering soonest. A similar question can get the answer already
-given. A cached prompt can be priced apart. Traces follow the OpenTelemetry
-GenAI conventions, and Kong is written down from trying it. Also an install
-guide with every screen, at `/install`.
-
-**Upgrading.**
-- Migrations 0049 (`mcp_servers`), 0050 (their rate and breaker) and 0051
-  (`projects.cache_similar`), applied when the control plane starts.
-- `llmgw server init` now refuses a machine that would serve models without
-  the memory for them: the starter model and the judges need 12 GB on one
-  machine, where 8 GB was said before. `--no-model`, `--no-guard-model` or
-  `--no-node` make it fit. A running cluster is not checked again.
-- Traces carry the GenAI conventions' `gen_ai.*` attributes beside the
-  `llmgw.*` ones, which stay; docs/install.md, "Tracing", lists them.
-- Nothing else changes until it is turned on: `services` and `restore` in a
-  guardrail policy, `keys cache --similar` with
-  `router.cache.embedding_model`, `cached_per_1k` in a price.
-
-### Added
-
-- **Answers to similar questions.** `llmgw keys cache --similar 0.95` also
-  gives a chat question the answer already given to one like it in the same
-  conversation, compared by `router.cache.embedding_model`, as
-  `x-llmgw-cache: similar` with the similarity. Held in memory beside the
-  exact answers; nothing written to the store but the setting.
-- **A cached prompt costs the cached rate.** `cached_per_1k` in a price
-  charges the prompt tokens an engine or provider read from its cache (the
-  answer's `cached_tokens`) at their own rate; without it they cost what any
-  prompt token does, as before.
-- **Chat goes to the replica answering soonest.** The router keeps each
-  replica's time to first token, smoothed over its last answers, and the
-  `chat` profile scores by it beside the queue and the KV cache: of two
-  replicas of one model, the one on the slower card or the busier host gets
-  less, and a replica not yet measured is tried.
-- **llmgw and Kong, written down** ([docs/kong.md](docs/kong.md)): Kong 3.9
-  in front of llmgw by a plain route or its `ai-proxy`, each team's llmgw
-  key passed on; Kong as a provider behind llmgw; and that Kong 3.9 counts
-  no completion tokens of a streamed answer, so bill from llmgw's usage.
-- **A guardrail that is someone else's service.** A policy's `services`
-  asks Azure Content Safety, Lakera, NeMo or a company's own classifier over
-  HTTP: a body template, keys from files, dotted paths to where the answer
-  says unsafe and why, on input, output or both, block or flag, and the
-  policy's `fail` when it does not answer.
-- **Redacted values put back in the answer.** `restore: true` on a guardrail
-  policy's input: the model reads `[EMAIL_1]`, the client reads its own
-  address in the reply, streamed or not. Only the request's own values, held
-  in memory for its life; the output rules read the answer as the client
-  will.
-- **Traces in the OpenTelemetry GenAI conventions.** An inference request
-  and each attempt at an engine carry `gen_ai.operation.name`, the requested
-  and the answering model, `max_tokens`, `temperature` and `top_p` when set,
-  the session as `gen_ai.conversation.id`, and the input, output and cached
-  tokens, and an attempt the engine that answered as `gen_ai.provider.name`.
-  Tools that read the conventions show llmgw's calls as model calls with no
-  dashboard of their own. No prompt or answer text is ever in a span.
-- **llmgw for VS Code.** An extension of llmgw's own, served by every gateway
-  at `/setup/vscode/llmgw.vsix` with that gateway's address in it, made from
-  the binary itself: plain JavaScript, no dependencies, no build, and so no
-  marketplace needed at a site with no internet. It offers the gateway's chat
-  models to VS Code's language-model API — the chat's model picker, agent
-  mode, and every extension that asks VS Code for a model — with the sizes
-  and the tool and vision capabilities the catalog says, streamed, with tool
-  calls and their results both ways. **VS Code** is a tool on the account
-  page's **Connect your editor**: a key, the one-line install, and an **Open
-  in VS Code** link that hands the key to the extension, which keeps it in
-  VS Code's secret storage. **llmgw: Sign In** opens that page with a state
-  of its own; a link without it is confirmed first, the gateway named.
-- **An install guide with every screen, at `/install`.** From three bare
-  Ubuntu machines to a first answer: what each machine needs and how to
-  check it, the release fetched and checked, the setup screens one by one,
-  the system's state, and a first request with a key from the account page.
-  The screens are a real three-machine install, recorded and kept as
-  terminal frames — sharp at any size and a few kilobytes — with each
-  session played back on request; the administrator's password and every
-  key were masked before it was kept. `/about` says more of what llmgw does
-  (documents, guardrails, sign-in, high availability, pictures and 3D), and
-  its install steps are the ones of today, leading to the guide.
-- **The company's MCP tools under the guardrails, a rate and a breaker.**
-  - **The answer:** the caller's policies read a tool's answer as the prompt it becomes. An instruction planted in a
-    ticket is withheld as a pasted one would be, and personal data is redacted.
-  - **The arguments:** they are read before they leave, so a secret pasted into one does not reach the company system.
-  - **Rate:** `ctl mcp add --rate N` allows each caller N calls a minute to a server.
-  - **Breaker:** five failures in a row take a server out for a minute, its tools off the list.
-
-- **How fast the judge is, measured.** `llmgw ctl guard judge check` (and `POST /api/v1/guard/judges/check`) works
-  out whether the judge keeps up with requests. It times three judgments of a 280-token prompt, then a burst at once,
-  and sets both against the policies' wait. It says ok, tight or slow, about how many requests a second can be judged,
-  and what to do: more cores, more judges, a GPU judge, a longer wait, or `fail: open`. `server init` runs it once the
-  judge is up. If the machine is too slow it says so before the next steps, not after the first refused request.
-
-- **The company's own MCP servers through llmgw's `/mcp`.** `llmgw ctl mcp add jira --url … --secret-file
-  Authorization=FILE` registers one; `/mcp` then lists its tools as `jira.search` beside llmgw's own. Only keys granted
-  them see them: `llmgw keys limits --tools 'jira.*'`, patterns at any level of the tenancy tree. None granted anywhere
-  is none. The server's credentials stay on the control planes, kept in the store sealed or read by reference. The
-  server is told the calling key, person and project. Each call is bounded in time and size, and its progress passes
-  on to a streaming client. Every call is in the audit log with its arguments' size and digest, never their text. The
-  admin API has `/api/v1/mcp/servers`.
-- **The cluster as a read-only MCP server.** Registered as `llmgw ctl mcp add llmgw --url llmgw:admin` and granted
-  as `llmgw.*`, its tools say what `llmgw ctl` does:
-  - `cluster_status`, `list_nodes`, `list_models`, `list_replicas`, `explain_placement`, `node_logs`;
-  - nothing that changes the cluster.
-
-  It is answered in the control plane's own process, so there is no token to keep and every control plane serves it.
-  The admin API serves the same at `POST /api/v1/mcp`. `ctl mcp add --bearer-file` keeps a token, sent as
-  `Authorization: Bearer`.
-
-- **Large models across cards and nodes.** For a model of experts on more than one card, the plan now adds vLLM's
-  `--enable-expert-parallel`. It reads the expert count from `config.json` under any of its names, and sizes a model
-  that also reads pictures by its `text_config`. Several nodes are offered in any number, not only powers of two. Each
-  way now says what it needs of a card, part by part (weights, context, engine), and of all its cards together. This
-  shows in `ctl model plan`, in the console's Serve a model, and in a serve job's first step. The serve form checks that
-  a longer context still fits. `ctl model serve --env KEY=VALUE` puts engine variables such as `NCCL_DEBUG=INFO` on
-  every node. docs/large-models.md has the rules, the commands, and a checklist for bringing a model up on a fabric.
-
-- **Machines of the judges' own in a three-machine install.** The setup screen asks for up to two judge machines after
-  the store's two; `server init` takes `--judge-node user@host` for each. Each is added as a node labelled
-  `llmgw.role: judge`, and the judge's profile selects it, so the judges run there alone. Under load on a 4-core
-  control plane that was also a node, 38 of 60 requests were refused for want of a judgment. With the judges on a node
-  of their own, 2 were. A node with an `llmgw.role` label takes only profiles whose node selector asks for that role,
-  so no other model is placed on the judges' machine.
-
-### Fixed
-
-- **A machine too small for the models it would serve is said so first.**
-  The control plane that is also a node, serving the starter model and two
-  judges, needs about 10.5 GB. On 8 GB the install finished every step and
-  then had no room for the starter. Now the setup's checks fail its memory
-  with what it would serve, and `server init` refuses before it installs
-  anything, naming `--no-model`, `--no-guard-model` and `--no-node`.
-
-- **Turkish pages are Turkish to the end.**
-  - **Errors:** those from the store, catalog and mirror that a page shows ("not found", "not empty", "already in the
-    catalog", the settings changed meanwhile, and others) are now in the page's language.
-  - **Percent:** a percentage is written the language's way: `%93` in Turkish, `93%` in English.
-  - **Footer:** the time at the foot of a page is in the language's date form.
-  - **Stale forms:** they are refused with a sentence in that language rather than "bad request".
-
-- **`llmgw keys limits` no longer clears the limits it was not given.** Setting one limit at a scope wrote the whole
-  row, so `--tools 'jira.*'` alone took away that scope's rate, budget and model list. Only what is given changes now.
-  `--replace` writes every limit, as the console's limits form does.
-
-- **The plan refused tensor parallelism past a model's KV heads.** Qwen3-235B, with four KV heads, had no way to run
-  on eight cards, though vLLM gives each card a copy of a head. A width that is a multiple of the KV heads is now
-  offered, as is one that divides them.
-- **A big model on a slow mirror was failed while it downloaded.** The startup timeout counted the download, so
-  hundreds of gigabytes at a few hundred MB/s ran past twenty minutes and the replica was started again from nothing.
-  The timeout now runs from when a node's download last moved.
-
-- **The judge init installs is no longer replaced by the leader's own.** Just after the control plane started, the
-  leader saw a policy naming a judge that init was still fetching, and served one itself. Its entry replaced init's, so
-  a second judge ran with the leader's sizing, and with judge machines it ran off them. The leader now waits ten minutes
-  after it starts before it serves a judge itself. If someone adds one while it fetches, theirs stays.
-- **A judge the leader serves by itself is sized as init's is.** When a guard policy names a judge the catalog lacks,
-  the leader serves it. That judge reserved 3 GB and no cores, and ran llama.cpp's prompt cache, which grew one to
-  3.2 GB. Without cores of its own, a judgment on a busy node missed its 5 s budget, and `fail: closed` refused the
-  request. It now gets what `server init` gives its judges: 2 GB, two cores each (fewer on a small node), and no
-  prompt cache. Every judge served through `modelserve` runs with `--cache-ram 0`.
-
-## v0.14.9 — 2026-10-19
-
-Sign-in set up from the console, with Active Directory tried before it is
-kept. A node's console now shows what the machine is doing, and a node's web
-page shows what it runs. Also fixes found trying Active Directory against a
-Samba domain controller on the test cluster. Sign-in through it, nested
-groups and a disabled account suspended by the sync all worked there.
-
-**Upgrading.**
-- No migration.
-- `auth.ldap` and `auth.oidc` are in the cluster's settings, as before. A
-  block written into `server.yaml` on a cluster with a store was never
-  read; the log said so. Put it in with `llmgw ctl config edit`, or set it up
-  again from the console's Sign-in screen.
-- A Samba DC's own autogenerated certificate is refused (a negative serial
-  and no SAN). Give it one from a CA.
-
-### Added
-
-- **Sign-in set up from the console.** Under People → Sign-in, `sudo llmgw` shows how people get in: single sign-on,
-  Active Directory and SCIM, each on or off. It also shows the directory's last sync. **E** sets up Entra ID from the
-  tenant and client IDs. **D** sets up Active Directory, and the directory is tried before it is kept: each server
-  reached and bound, how many people may sign in, how many are in each group. Nothing is kept if a step fails. The
-  password, client secret and SCIM token are kept in the store as `store:auth/…`, sealed by the master key. The
-  domain's CA goes into the settings (`auth.ldap.ca`), so no file has to be put on each control plane. The admin API
-  has the same: `GET /api/v1/auth`, `POST /api/v1/auth/ldap/test` and `PUT /api/v1/auth/secrets/{name}`.
-- **A node's page says what it runs.** It now shows the agent's version, marked when the control plane runs another,
-  and the engines with their versions. Each GPU row now names the models loaded on that card, and each engine row its
-  GPUs.
-- **`sudo llmgw` on a node opens on what the machine is doing.** A new Overview screen shows the agent's state and
-  version, each control plane it dials and whether it answers, every GPU with the models on it, the engines running
-  here, the free space for weights and engines, and the agent's warnings of the last hour. It is read on the node
-  itself, every three seconds, so it needs no admin token and works while the control plane is out of reach.
-
-### Fixed
-
-- **A broken `auth.ldap` no longer stops every control plane.** It is the cluster's setting. A CA file that one
-  machine could not use made `llmgw server` exit on every control plane, and no `ctl config` could then put it right.
-  Directory sign-in is now turned off on that control plane, with an error in its log. Local accounts still sign in.
-- **A second `llmgw server` on a machine stops before it competes to lead.** `llmgw server check` (no such command)
-  ran a whole server. Its ports were taken, yet it went on to hold the leader's lease for three hours while the real
-  control planes stood by. `server` now refuses words it does not know and takes its ports before anything else.
-- **The single sign-on and Active Directory guides said `server.yaml`.** On a cluster with a store, `auth` is in the
-  cluster's settings and the file's block is not read. They now say `llmgw ctl config edit`, and what certificate a
-  domain controller needs.
-
-## v0.14.8 — 2026-10-18
-
-Sign-in with an on-premises Active Directory, and Entra ID made safe for
-people in many groups. Also several keys for one outside provider, and a
-measure of what the gateway adds to a request.
-
-**Upgrading.**
-- Migration 0048 adds the `user_directory` table, applied when the control
-  plane starts.
-- Nothing changes until `auth.ldap` is set; docs/install.md, "Active
-  Directory", has an example. It has been tested against a fake directory,
-  not yet against a real domain controller.
-- A judge installed by an earlier `server init` is refitted by the leader
-  by itself (below); the steps given for v0.14.7 are no longer needed.
-
-### Added
-
-- **Sign-in with Active Directory** (`auth.ldap`). People sign in on the gateway's form with their AD username or mail
-  and password, checked against the domain controllers over LDAPS or StartTLS. Groups, nested ones included, give
-  staff roles and places in the tree, as with OIDC. Accounts are tied to the `objectGUID` and made at first sign-in
-  when `create_accounts` is on. Every 15 minutes the leader reads the directory. People disabled or deleted there are
-  suspended and reinstated when they come back; roles and memberships follow their groups. A sync that would suspend
-  more than half the accounts is refused. See docs/install.md, "Active Directory".
-
-- **Several keys for one outside provider.** An external model takes `api_key_files`, each with an optional weight, in
-  place of `api_key_file`. Each key is an endpoint of its own (`external:MODEL#1`, `#2`), so a key answering 429 is
-  passed over while its breaker is open and the request goes to another. A key answering 401 is passed over too, and
-  `external_key_refused` is sent, naming the endpoint, never the key. Usage records which key answered by that name.
-
-- **`llmgw ctl bench overhead`**: what the gateway adds to a request, measured against an engine that answers at
-  once. Gateway and engine run in one process on loopback, so no cluster is needed. The load is sent straight to the
-  engine and through the gateway: bare, with authentication and accounting, and with the guardrails' pattern checks.
-  It reports p50 and p99 latency, what the gateway added, and a rough CPU per thousand requests. On an Apple M5 the
-  gateway added 0.05–0.42 ms at p50 and at most 0.49 ms at p99 (README).
-
-### Fixed
-
-- **Entra ID's groups past 200 no longer take a role away.** For someone in more than 200 groups Entra sends none in
-  the token, only a pointer to Graph. That was read as no groups, so an administrator lost their role at the next
-  sign-in. Their role and memberships are now left as they were, and an error is logged saying what to change in the app
-  registration. docs/install.md has an Entra ID section.
-- **An account made by SCIM or OIDC could not be reinstated.** Setting it active was refused as "never approved".
-- **An upgrade refits the judge an earlier `server init` installed.** Upgrading to v0.14.7 left such a judge as it was:
-  no cores or one, 2 or 4 GB, the prompt cache on. On fewer than eight cores every request was refused until it was
-  fixed by hand. Now the leader finds a judge whose entry is exactly what an earlier init wrote and gives it 2 GB, no
-  prompt cache and cores by today's rule (up to four for one judge, two each for more). It then restarts the judge's
-  replicas onto that. The number of replicas is left as it is. A judge whose entry was changed by hand is left alone,
-  and the log says so once.
-- **A restart is no longer refused for room another restart is giving back.** With every core of a node reserved, two
-  models restarted together, one to need more and one less (as after `ctl model resources` on a judge and a starter),
-  had the first refused: "fits on no node even with this replica stopped", though the second was about to give back
-  its cores. A restart now waits for other restarts under way, up to the drain grace, before it is refused. A drained
-  replica also counts a replica being restarted that still answers as serving, so replicas restarted one after
-  another no longer wait out the five-minute grace each.
-
-## v0.14.7 — 2026-10-16
-
-The judge installed by `server init` sized for what it does. On a machine
-of fewer than eight cores v0.14.6 left every judgment past its budget, so
-`fail: closed` refused every request. A single-machine install of v0.14.7
-on a 4-core VM passed 20 of 20, and on 8 cores 20 of 20 under load.
-
-**Upgrading.**
-- No migration.
-- **Upgrading does not change a judge already in the catalog.** v0.14.6
-  and earlier installed two judges, reserving no cores or one, and 2 or
-  4 GB. To give them what they need:
-  `llmgw ctl model resources qwen3guard-0.6b --memory 2 --cores 2`, then
-  `llmgw ctl restart --model qwen3guard-0.6b`. The two then need four cores
-  on a single machine; below that, a longer `latency_budget` or
-  `fail: open`.
-- On a node whose cores are all reserved, `ctl restart --model` cannot
-  start the new replica beside the old one and waits. Stop the old engine
-  process, and the replica comes back with the new figures.
-
-### Fixed
-
-- **Both judges fit an 8 GB machine again.** v0.14.6 had `server init` reserve 4 GB a judge replica. That figure came
-  from one replica at 3.2 GB after a day of traffic. The growth was llama.cpp's prompt cache, up to 8 GB by default,
-  which a judge never reuses: each text it reads is different. On a 4-core, 8 GB machine the second judge then fitted
-  nowhere ("has 7 GB of memory with 1 free, needs 4"). The judge now runs with `--cache-ram 0`, uses about 1.6 GB and
-  stays there, and reserves 2.
-- **One machine runs one judge, on up to four cores.** A second replica on the same machine shares its cores and is
-  lost with it, so it bought nothing but half the speed of each. `server init` on a single machine now serves one judge
-  on up to four cores (2.3 s a judgment where two on two cores took 4.2). Where there will be other nodes, it serves two
-  on two cores each, as in HA setups. `--judge-replicas` and the setup's Copies still choose.
-- **A judge gets the two cores it needs.** v0.14.6 gave each judge replica one core on machines under eight. A judgment
-  of about 280 tokens takes 8.0 s on one core, 4.2 s on two and 2.3 s on four, against the 5 s budget, so on a 4-core
-  machine every judgment timed out and every request was refused. Where there are two judges, each now reserves two
-  cores (one only below four CPUs), and the one judge of a single machine up to four; the starter has what is left, or
-  shares when nothing is. A judge on two cores stays close to its budget: give it more cores or a GPU, or raise
-  `latency_budget`, where requests must not wait.
-
-## v0.14.6 — 2026-10-16
-
-Setup that says what each part of an install is and lets every one be
-chosen and set; three machines that each run the gateway, so any one can
-be lost; a cluster that loses its store's primary without losing a
-request; one ComfyUI for an environment's models; pictures, 3D and
-workflows as MCP tools; alerts asked for at setup; extended thinking.
-
-**Upgrading.**
-- No migration.
-- **Control planes**: with `control.lease_ttl` unset the lease is now 10 s
-  (was 15). Upgrade the standbys first and the leader last; a mix of
-  versions meanwhile is fine.
-- **The store** (PostgreSQL): each member is dialled for 3 s before the
-  next is tried. A store so far away that connecting takes longer needs
-  `connect_timeout=10` in its address.
-- **Nodes** notice a control plane that died without closing its
-  connection in 8 s (was 15) once they run this release.
-- **Judges installed by an earlier `server init`** keep reserving no cores
-  and 2 GB. To give them their own:
-  `llmgw ctl model resources qwen3guard-0.6b --memory 4 --cores 2`, then
-  `llmgw ctl restart --model qwen3guard-0.6b`.
-- **Patroni** replaces a lost primary within 20 s on a new cluster. On an
-  existing one, run `server init --patroni ...` again from the machine with
-  the authority; it changes only that.
-- **A floating address** keeps VRRP router id 51 until `server add --vip`
-  runs again, which moves it to one of its own; run it for every standby.
-- A request whose judge is not there yet waits up to the policy's
-  `latency_budget` for one before `fail: closed` refuses it.
-
-### Added
-
-- **Setup lets every part be chosen, each with its settings, and says what each is.** `sudo llmgw` on a new machine lists
-  the parts of an install: the control plane, the store, the model mirror, this machine as a node, the starter model,
-  pictures and 3D, the guardrails' judge, the firewall, notifications, limits and keys, on-demand turns, an offline
-  bundle. Beside each is what it will be or what is missing without it. Space turns a part on or off, and Enter opens
-  its settings in a dialog that explains it at more length. The settings are: which starter model (six Qwen sizes, or
-  any GGUF on Hugging Face) and its context; the mirror's directory or another machine's mirror; the judge's
-  categories, copies, wait and what happens when it does not answer; the portal's language; the sign-up form; the
-  default limits; the longest a key lives; the on-demand waits. A plan page then lists what is installed and what is
-  left out, with the same install as a command. Every setting is a `server init` flag too (`--starter`,
-  `--judge-fail`, `--media`, `--max-key-ttl`, ...).
-- **Three machines are high availability for the gateway, not only the store.** With three machines, setup makes the two
-  database machines control planes too, standing by while the first leads, with an optional floating address
-  (keepalived) that follows whichever leads. Any one machine can now be lost. By command: `server init --patroni ...
-  --standbys --vip 10.0.0.160/24`. The mirror's management API answers the three control planes, so a standby that
-  comes to lead can still fetch models.
-
-- **Pictures uploaded to work from**: `/v1/files` takes `purpose=vision` or
-  `user_data` besides `batch`, kept as long as job results, so a picture is
-  sent once and named by its `file-…` id in the MCP tools and a workflow's
-  inputs.
-- **One ComfyUI for an environment's models**: ComfyUI models in one
-  `comfyui.environment` (two or more) share one replica — the catalog
-  makes it a hidden entry, `comfyui-env-<name>`, on the first member's
-  profiles with the most memory any member needs, carrying every member's
-  weights and custom nodes. Asking for any member starts it; it answers for
-  each with that member's workflow and checkpoint, and the members get no
-  replicas of their own. A picture model and a 3D model on one card stop
-  handing it to each other with a cold start each way.
-- **Pictures, 3D models, vision and workflows as MCP tools** at `/mcp`,
-  beside the memory notes, each offered only where the gateway has a model
-  for it: `generate_image` (with `concept`, `side` and `texture` styles),
-  `generate_mesh` (from a picture or a prompt), `review_images` (a vision
-  model, to a JSON schema), `run_workflow`, `job_status` and
-  `gateway_status`. Each makes its request under the caller's key, so
-  allowlists, limits, licences and budgets apply and it is charged like
-  any request; what it makes is kept as the caller's file and answered by
-  id and download URL. A client that takes a stream gets
-  `notifications/progress` while a mesh is made and waits up to ten
-  minutes; one that does not, 50 seconds, then the job id.
-- **Setup asks where alerts go**: `llmgw server init --webhook URL`
-  (repeatable) and a **Notification webhooks** field on both setup screens.
-  Slack's, Mattermost's and Rocket.Chat's addresses are sent Slack's text,
-  any other the event as JSON (`slack:` or `json:` in front says which).
-  They are added to the cluster's `notify.webhooks` beside those already
-  there, and each is sent a test once the control plane runs on them.
-
-- **Extended thinking on `/v1/messages`**: `thinking: {type: "enabled"}`
-  tells a model that thinks by its chat template to (`enable_thinking`),
-  and its reasoning comes back as `thinking` blocks before the text,
-  streamed as `thinking_delta` events; `disabled` tells it not to. Not
-  asked for, the reasoning is left out as before.
-- **How long on-demand models hold a card** is a setting, in force on the
-  leader within seconds: `on_demand.evict_after_idle` (2m unless set) and
-  `on_demand.min_lifetime` (5m). On one card shared by a picture model and
-  a 3D model, 1m each brings the wait between a picture and its mesh to
-  about a minute.
-
-### Fixed
-
-- **The judges and the starter model divide a machine's CPUs instead of each taking all of them.** `server init` gave the
-  judge and the starter no cores of their own, so every llama.cpp engine ran on every core: two judges and the starter
-  on a 4-core control plane competed, and under load 38 of 60 requests were refused for want of a judgment. Moved to a
-  node of their own with 2 cores each, the same test refused 2. When this machine is the node, init now gives each judge
-  replica 1 core (2 from 8 cores) and the starter what is left (at most 8); judges bound for other nodes get 2 each. A
-  judge also reserves 4 GB, not 2: it uses about 3.2.
-
-- **A lost store machine stops costing requests most of a minute.** The store's connections try each member for 3 seconds,
-  not until the kernel gives up, and a connection to a machine that is gone is closed within about 10 seconds (TCP
-  keepalive, and `TCP_USER_TIMEOUT` on Linux). Patroni replaces a lost primary within 20 seconds (`ttl` 20, `loop_wait`
-  5, `retry_timeout` 5). Running `server init --patroni` again applies this to an existing cluster. Measured on three
-  VMs with the primary's power cut: about 45 seconds of hanging requests before.
-- **Leadership stays put while the store's primary is replaced.** Replacing a lost primary takes longer than the
-  leadership lease lives, so the lease had lapsed for everyone by the time the store answered again. Whoever asked first
-  took it, as often a standby as the leader. A standby that saw the store out of reach now leaves the lease alone for one
-  round after it returns, so the leader renews it, and a leader that is truly gone is replaced a round later. With that,
-  the default lease is 10 seconds (was 15). A node notices a control plane that died without closing its connection in
-  8 seconds (was 15), so it is on its way to the new leader as that one takes over.
-- **A judge replica that hangs no longer costs the request.** All the tries of a judge request shared the policy's
-  budget, so a replica that hung used it all and the try on another replica had none left: under `fail: closed` the
-  request was refused while a judge stood idle. When the first replica has not answered by half the budget, the same
-  question now goes to a replica on another machine too, and the first answer is taken. The first replica is not cut
-  short, which on a slow machine would refuse answers it was about to give. Replicas on one machine whose CPUs are taken
-  are slow together, so asking both only doubles the work there: measured that way, as many requests failed as before.
-  On such a machine the remedy is room, not a second question: judges on more than one node, more cores, or the judge
-  on a GPU.
-- **A new leader waits for the judge instead of refusing at once.** The moment a control plane takes the lead it knows no
-  judge yet. When every judge fails at once, they are asked again every 250 ms while the policy's `latency_budget` lasts,
-  so `fail: closed` no longer answers every request in those seconds with 503 (about 17 seconds of them in the test). A
-  judge that is slow is not asked again, and an alarm is raised once per request, not once per try.
-
-- Node discovery for Prometheus listed only the control plane asked and the
-  store, so a machine that is both was a control plane to one and a store
-  member to the other — scraped twice — and a standby asked alone lost every
-  node. Every control plane lists all of them alike; deploy/monitoring's
-  prometheus.yml says to scrape and ask each.
-- A model whose weights and context pool did not fit its card was added
-  and then failed to make its context on every start, taking the card from
-  others each time (Apertus 70B with a 65536-token pool, 8B with 131072, on
-  24 GB). `ctl model serve` shrinks the pool to what the card holds, saying
-  so, and refuses weights that do not fit at all; the portal's serve form
-  refuses such a pool and says the largest that fits.
-- Removing weights from the mirror that a catalog model still loads is
-  refused, naming the model: removed from the mirror alone, the model stayed
-  in the catalog and its replicas went on loading the node's copy.
-- Jobs ran one at a time, so a 3D job waiting for the card held up another
-  model's job that could have run. They run side by side, one per model at
-  a time and eight in all, on the leader as before.
-- `llmgw ctl model serve` served an embedding model as a chat model: no
-  `--embedding`, four slots, a 512-token batch, `embeddings` unset and a
-  "say hello" smoke test it could not pass. A model whose GGUF says it
-  pools (or `--embeddings`) is served for embedding: 32 slots of 1024
-  tokens unless sized otherwise, a batch that holds a whole passage, and
-  one vector asked for as its smoke test.
-- `llmgw ctl upgrade` checks every node's version once the waves are done
-  and fails naming any not on the release, and says when the control plane
-  has no nodes registered; `llmgw upgrade` on a control plane says how many
-  nodes it left behind and the command that upgrades them. A site's nodes
-  stayed a release behind with nothing to say so.
-- The cluster and node pages swapped their live part every few seconds,
-  forms and all, so filling one in raced the clock: what was typed, an

-|---|---|---|
-| bare | 0.06–0.24 ms | 0.10–0.33 ms |
-| with authentication and usage accounting | 0.05–0.32 ms | 0.09–0.37 ms |
-| with the guardrails' pattern checks as well | 0.10–0.42 ms | 0.15–0.49 ms |
-
-The range is across 100 to 2,000 requests a second. The overhead was
-*lowest* at 2,000, most likely because a busier processor keeps its cores
-awake. The guardrails' judge model is not in these figures: a judgment
-takes seconds on CPUs (see [install.md](docs/install.md)) and is a model's
-time, not the gateway's.
-
-The command also prints the gateway's CPU per thousand requests. Gateway,
-engine and load share one process there, so that figure is rough (0.04 to
-0.65 s per thousand in the run above); the latency is the one to quote.
-Figures from a VM on a busy host move with the host: run it where you will
-deploy, and keep the load it prints beside the result. CI runs a one-second

Answers the PNG's `file_id`, `url` and `seed`, with a 512 px preview to look at. |
-| `generate_mesh` | A GLB from a picture — `image` is a `file-…` id (a `generate_image` result, say), a data URL or base64 — or from a `prompt`, for which a concept picture is made first. `seed`, `resolution`, `texture_resolution`, and any other input the model's workflow declares in `inputs`. Answers the GLB's `file_id`, `url` and licence. |
-| `review_images` | Asks a vision model about one to four pictures (each shrunk to 1280 px on its long side); `json_schema` makes it answer that JSON. |
-| `run_workflow` | Runs a ComfyUI workflow from the inputs its catalog entry declares, and answers its result file. |
-| `job_status` | Where a mesh or a workflow run stands, and its file when done; `wait_seconds` waits for it. |

-```
-
-- **Credentials:**
-  - `--secret-file NAME=FILE` reads a header's value once and keeps it in
-    the store, sealed by the master key, so no file has to be on each
-    control plane.
-  - `--header-ref NAME=REF` reads it at each call from a file, `env:`,
-    `vault:` or `store:` instead.
-  - `--header NAME=VALUE` is for what is not secret.
-- **Who may call what:** tools are named `server.tool` and granted as
-  patterns (`jira.*`, `db.query`) at any level of the tenancy tree, as
-  models are.
-  - A level that names any narrows what is above it: a tool is seen where
-    every level above that names tools names it too. A team under an
-    organization that names `hr.*` sees no `jira.*` whatever the team is
-    given, until the organization names it as well.
-  - Unlike models, **none granted anywhere is none**: a tool reaches into a
-    company system, so it is granted, never assumed.
-  - `keys limits --tools` writes a level's list whole, every server's
-    together; an empty list (`--tools ''`) closes the level to every tool.
-    The console's **MCP servers** screen and the `/admin/mcp` page grant
-    and take back one server's tools: a level given its first list starts
-    from the nearest list above it, so it keeps what it saw; one left
-    naming none goes back to naming none, or stays closed when a level
-    above names tools, so taking one server away opens it to no other. They
-    say when a level above keeps the granted tools out of reach.
-- **The server is told who calls:** `X-Llmgw-Key`, and `X-Llmgw-User` and
-  `X-Llmgw-Project` where there are some. It is called with llmgw's
-  credentials, never the caller's key.
-- **Bounds:** a call has 60 seconds (`--timeout`) and an answer 4 MB. A
-  server's progress is passed on to a client that takes a stream. `--rate N`
-  allows each caller N calls a minute to a server's tools.
-- **Guardrails, both ways:** the caller's policies read a tool's answer as
-  the prompt it becomes.
-  - An instruction planted in a ticket is caught as a pasted one would be
-    (`injection: block`).
-  - Personal data is redacted or refused as the policy says. A refused
-    answer does not reach the agent.
-  - The arguments are read before they leave, so a secret pasted into one
-    does not reach the company system.
-- **A server that keeps failing:** five calls failing in a row take a server
-  out for a minute. Its tools leave the list, and a call is answered at once.
-- **Record:** every call is in `llmgw ctl audit`, with its arguments' size
-  and a digest, never their text. `llmgw_mcp_tool_calls_total` and
-  `llmgw_mcp_tool_call_seconds` count them by server, tool and outcome.
-- **Changes:** a server added, changed or removed on one control plane is
-  served by every one within half a minute; its tool list is read again
-  every five minutes. `--disabled` keeps a server but serves none of its
-  tools.
-
-**This cluster's own, read only.** `llmgw ctl mcp add llmgw --url
-llmgw:admin` registers the cluster itself as a server: tools that say what
-`llmgw ctl` does, and change nothing. It is answered in the control plane's
-own process, with no address and no token to give.
-
-| Tool | Says |
-|---|---|
-| `llmgw.cluster_status` | control planes, store, nodes, models against what they asked for, GPUs, what is unhealthy |
-| `llmgw.list_nodes` | each node's state, GPUs, load, fabrics, agent version and engines |
-| `llmgw.list_models` | each model's replicas ready against wanted, profiles, why one is parked |

-### Entra ID
-
-The console sets this up: `sudo llmgw`, People → Sign-in, **E**. What
-follows is what it writes, and what to do in Entra.
-
-Entra ID is an OpenID Connect provider like the others, with two things to
-set in the app registration:
-
-1. **Redirect URI:** under Authentication, add a Web platform with
-   `https://<gateway>/login/oidc/callback`. The issuer is
-   `https://login.microsoftonline.com/<tenant-id>/v2.0`.
-2. **Groups in the token:** under Token configuration, add a groups claim.
-   Choose **Groups assigned to the application**, and assign the groups you
-   map in `roles` and `memberships` to the enterprise application. Entra
-   sends groups by object id unless you choose to emit names
-   (`sAMAccountName` for groups synced from AD), so write them the same way
-   in the mapping.
-
-Entra leaves the groups out of the token for someone in more than 200 of
-them and sends a pointer to Graph instead. llmgw then keeps that person's
-role and memberships as they were, rather than reading it as no groups, and
-logs an error saying so. "Groups assigned to the application" avoids this.
-So does SCIM below, which Entra also speaks: in the enterprise application
-under Provisioning, set the tenant URL to `https://<gateway>/scim/v2` and
-the secret token to the contents of `auth.scim.token_file`.
-
-## Active Directory
-
-With an on-premises Active Directory, people sign in on the gateway's own
-form with their AD username (`ada`, `CORP\ada`, `ada@corp.example`) and
-password. The gateway checks them with the domain controllers over LDAPS.
-
-The console sets this up and tries it first: `sudo llmgw`, People →
-Sign-in, **D**. It keeps the service account's password in the store
-(`bind_password_file: store:auth/ldap-bind`) and writes the CA into the
-settings (`ca:`), so nothing has to be copied to each control plane.
-By hand it is this block in the cluster's settings (`llmgw ctl config
-edit`), where files it names must then be on every control plane:

-
-- **Service account:** an ordinary domain user is enough: it only reads.
-  It finds the person and reads their groups. The person's password is
-  checked by binding as them, and is never stored.
-- **Encryption:** `ldaps://`, or `ldap://` with `start_tls: true`.
-  Plaintext LDAP is refused, since passwords would cross the network.
-- **Certificate:** the domain controller's certificate must name it in
-  its subject alternative names: a name in the CN only is refused, as are
-  certificates with a negative serial number. Samba's own autogenerated
-  certificate is both, so a Samba DC needs one from a CA (`tls certfile`
-  in smb.conf). A CA file a control plane cannot read turns directory
-  sign-in off on that control plane, said in its log. Local accounts still
-  sign in.
-- **Who may sign in:** enabled user objects under `base_dn` that match
-  `user_filter`. The example admits members of `llmgw-users`, nested groups
-  included.
-- **Accounts:** an account is tied to the person's `objectGUID`, so a changed
-  mail or name is still the same account. An account that already exists
-  with the person's mail is taken over. Without `create_accounts`, only
-  people who already have an account can sign in. Local accounts, such as
-  the administrator `server init` made, keep signing in with their own
-  password.
-- **Sync:** every `sync_interval` the leader reads the directory.
-  - Someone disabled or deleted in AD is suspended and their sessions
-    end.
-  - When they are enabled again they are reinstated. An account an
-    administrator suspended by hand stays suspended.
-  - Roles follow groups, and memberships the directory gave are taken away
-    when the person leaves the group.
-  - A sync that would suspend more than half of the directory's accounts is

-# llmgw and Kong
-
-For a site that already runs Kong. The two meet over plain HTTP: Kong in
-front of llmgw, as one more API it governs, or Kong behind llmgw, as an
-OpenAI-compatible provider. Nothing of either is built into the other.
-
-Tried with Kong Gateway 3.9 (`kong:3.9`, the last open-source release; 3.10
-and later need a Kong licence) in DB-less mode, in front of llmgw.
-
-## Kong in front of llmgw
-
-Two ways, both tried.
-
-**A plain route.** Kong forwards the request as it came. Tried with chat
-completions, streamed and not; llmgw's other APIs — Anthropic's
-`/v1/messages`, `/v1/responses`, embeddings, pictures — go the same way,
-since Kong does not read them. Kong adds its own authentication, rate limits
-and logging; llmgw still checks the key, the budget and the guardrails.
-
-```yaml
-_format_version: "3.0"
-services:
-- name: llmgw
-  url: https://llm.example.com          # llmgw's client port
-  routes:
-  - name: llmgw
-    paths: [/llmgw]                      # /llmgw/v1/chat/completions → /v1/chat/completions
-```
-
-**Kong's `ai-proxy` plugin**, for Kong's own token statistics on a chat
-route. llmgw is an OpenAI provider whose `upstream_url` is llmgw:
-
-```yaml
-services:
-- name: llmgw-chat
-  url: https://llm.example.com
-  routes:
-  - name: chat
-    paths: [/chat]
-  plugins:
-  - name: ai-proxy
-    config:
-      route_type: llm/v1/chat
-      logging: {log_statistics: true, log_payloads: false}
-      model:
-        provider: openai
-        name: qwen-coder                 # a model llmgw serves
-        options:
-          upstream_url: https://llm.example.com/v1/chat/completions
-```
-
-**Keys.** Without an `auth` block, `ai-proxy` passes the client's
-`Authorization` header on: each team keeps its own llmgw key, and llmgw's
-budgets, limits, guardrails and usage stay per team. With
-`auth: {header_name: Authorization, header_value: "Bearer sk-llmgw-…"}` Kong
-sends one key of its own instead, and llmgw sees every caller as that key —
-then budgets per team are Kong's to keep.
-
-**What Kong counts.** For a whole answer Kong reads llmgw's `usage` and
-records prompt and completion tokens as llmgw did. For a streamed answer
-Kong 3.9 records an estimate of the prompt tokens and no completion tokens,
-even with `stream_options.include_usage` set — the usage chunk reaches it
-and is not read. llmgw's own accounting counts both; use its usage export
-(`llmgw ctl usage export`) or `/admin/usage` for figures to bill by.
-
-**Timeouts.** A long answer from a model still loading outlasts Kong's
-60-second defaults: set the service's `read_timeout` to the time a model may
-take to start, as for nginx in [install.md](install.md).
-
-## Kong behind llmgw
-
-Not tried here. Kong's AI routes speak OpenAI's API, so llmgw reaches models Kong fronts as
-it reaches any provider: a model whose source is `external`.
-
-```yaml
-- name: kong-gpt
-  source: external
-  external:
-    url: https://kong.example.com/openai     # Kong's route, without /v1
-    model: gpt-4o-mini
-    api_key_file: /etc/llmgw/secrets/kong-consumer.key
-```
-
-The key is the one Kong's own authentication asks of a consumer. As a
-fallback (`fallbacks: [kong-gpt]`) it is used only when the cluster has no
-room.
-
-## Which to choose
-
-Kong in front when the site's API policy says every API goes through Kong:
-llmgw is then one more upstream, and its per-team accounting still holds
-when each team keeps its own key. Kong behind when the site already reaches
-outside providers through Kong and llmgw should too. llmgw does not need
-Kong for anything it does itself — keys, budgets, guardrails, routing to
-its own replicas.

-# Large models: several cards, several nodes
-
-A model too big for one card runs on several. llmgw chooses how from the
-model's own figures and the cluster as it is; this page is the rules it
-follows, the commands, and what to look at when a first one is brought up
-on new hardware.
-
-## How a model is split
-
-In order, the first that fits:
-
-1. **One card.** Nothing to split.
-2. **Several cards of one node, tensor parallel.** Every layer is cut
-   across the cards, so they talk for every token: they must be on one
-   NVLink domain. The agent reads `nvidia-smi topo -m` and gives a replica
-   the cards with the most NVLink between them
-   ([install.md](install.md#nvlink-if-your-gpus-have-it)).
-3. **Several nodes, pipeline parallel between them.** Each node holds a
-   run of layers on all its cards (tensor parallel inside it), and only a
-   layer's output crosses to the next node. The nodes must share one
-   InfiniBand or RoCE fabric: a replica never spans two, and never a node
-   with none. Any number of nodes, not only two or four.
-
-The plan takes the fewest cards, then the fewest nodes, then the better
-precision up to eight bits.
-
-**Tensor width and the KV heads.** The cards split the model's KV heads
-among them, or past their number each card holds a copy of one. So the
-width divides the KV heads or is a multiple of them: a model with 8 KV
-heads runs 2, 4, 8 or 16 wide, not 12. Qwen3-235B has 4 and runs on 8.
-
-**Mixture of experts.** A model of experts (Qwen3-235B-A22B, DeepSeek-V3,
-Llama 4, Mixtral) on more than one card is served with vLLM's
-`--enable-expert-parallel`: each card holds whole experts rather than a
-slice of every one, which is less traffic per token. It is read from
-`config.json` (`num_experts`, `n_routed_experts`, `num_local_experts`).
-
-**When it does not fit.** A smaller precision first: an FP8 or AWQ
-repository of the same model, or a GGUF quantisation on llama.cpp if one
-node's cards hold it. Then more nodes. `llmgw ctl model plan REPO
---precision bf16,fp8` shows each precision's fit from the model's config.
-
-## What a way needs
-
-Each way the plan offers says what a replica needs of each card, part by
-part, and of all its cards together:
-
-```
-$ llmgw ctl model plan meta-llama/Llama-3.3-70B-Instruct --format safetensors --context 32768
-FILE      SIZE    BEST WAY        A CARD   OF     ALL CARDS  NOW
-original  131 GB  4 × h100-80g    37.4 GB  72 GB  150 GB     free
-
-Best: original on 4 × h100-80g: 37.4 GB a card (weights 32.9 + context 2.5 + engine 2.0) of 72 usable; 150 GB on 4 cards.
-The context costs 0.31 GB per 1000 tokens, the whole model (--context to plan another).
-```
-
-- **weights:** the files, divided over the cards.
-- **context:** the KV cache for the context planned, divided likewise.
-- **engine:** the engine's own: 2 GB and a fiftieth of the weights for vLLM.
-- **usable:** 90% of a card; the rest is the driver's and fragmentation's.
-
-The console's **Serve a model** shows the same for every way a file runs.
-A context longer than planned is checked against it before anything is
-fetched.
-
-## Serving one
-
-Without flags the plan's best way is taken:
-
-```
-llmgw ctl model serve Qwen/Qwen3-235B-A22B-Instruct-2507-FP8 --format safetensors --context-length 32768
-```
-
-Or a way given by hand, for instance two nodes of eight:
-
-```
-llmgw ctl model serve meta-llama/Llama-3.3-70B-Instruct --format safetensors \
-    --gpu-class h100-80g --gpus 8 --nodes 2 --env NCCL_DEBUG=INFO
-```
-
-`--gpus` is the cards on each node and `--nodes` the nodes. The pipeline
-is the nodes and the tensor width the cards of each.
-
-`--env KEY=VALUE` goes into the engine's environment on every node:
-`NCCL_DEBUG=INFO` while bringing a cluster up, `NCCL_IB_*` to steer it.
-Only the variables engines are tuned with are taken. llmgw already sets
-these:
-- `NCCL_IB_HCA` to the fabric's adapters;
-- `NCCL_IB_GID_INDEX` on RoCE;
-- `NCCL_SOCKET_IFNAME` to the management network;
-- for an NVLink domain spanning nodes, `NCCL_MNNVL_ENABLE`.
-
-The job's first step says what it needs of each card. The weights then
-come to the mirror once and from it to each node. The startup timeout (20
-minutes unless the profile's `startup_timeout` says otherwise) runs from
-when a node's download last moved. So a model of hundreds of gigabytes is
-not failed while it is still arriving, and one whose download stops is
-failed that long after.
-
-## Watching it come up
-
-| What | Where |
-|---|---|
-| The replica and its shards, one per node, each with its download | `llmgw ctl replicas` |
-| Why it is not placed | `llmgw ctl explain-placement MODEL` |
-| A node's engine output (NCCL's lines with `NCCL_DEBUG=INFO`) | `llmgw ctl logs NODE --source SHARD` |
-| The bandwidth between two nodes, rail by rail | `llmgw ctl fabric-test NODE NODE` |
-| Each node's GPUs, NVLink and adapters | `llmgw doctor` on the node; its page under /admin |
-| Every step of a start, across nodes | the `replica start` trace ([install.md](install.md)) |
-
-With `NCCL_DEBUG=INFO`, NCCL says which transport it took between nodes:
-`NET/IB` is the fabric. `NET/Socket` means it fell back to TCP, and the
-model will run, slowly.
-
-## Bringing it up on new hardware
-
-A first run on a fabric, in order. Each step is worth its output if
-something goes wrong.
-
-1. **The nodes.** Add each with its fabric:
-   `llmgw node add host --fabric ib-a:mlx5_0,mlx5_1`. Then
-   `llmgw ctl nodes` shows every node ready, on `ib-a`.
-2. **The fabric.** `llmgw ctl fabric-test node1 node2`: each rail at its
-   rated speed (a 400 Gb/s rail near 45 GB/s).
-3. **One node, several cards.** A dense 70B at bf16 on four or eight
-   cards of one node, by the plan:
-   `llmgw ctl model serve meta-llama/Llama-3.3-70B-Instruct --format safetensors`.
-   Ready, then a question answered.
-4. **Two nodes.** The same model forced over two:
-   `--gpu-class CLASS --gpus 8 --nodes 2 --env NCCL_DEBUG=INFO`, under
-   another `--name`. Ready, answering, and `NET/IB` in both shards' logs.
-5. **Experts.** A mixture-of-experts model on one node's eight cards,
-   for instance `Qwen/Qwen3-235B-A22B-Instruct-2507-FP8`: its profile
-   carries `--enable-expert-parallel` (`llmgw ctl models`, or its
-   definition from the admin API).
-6. **A node lost.** With the two-node replica serving, stop one node's
-   agent (`systemctl stop llmgw-agent`): the replica fails and is placed
-   again once the node is back or another has room. Nothing is left
-   holding cards.
-
-For each, worth keeping:
-- the time from serve to ready;
-- tokens a second from `llmgw ctl bench`;
-- the plan's per-card figure against what `nvidia-smi` shows once loaded;
-- anything it said that was wrong.

-Hugging Face, showing only what your nodes can run: judged by the cluster as it
-is now — the largest card and its compute capability, the most memory on one
-node — so a model too big for them, in a form those cards lack (FP8 needs 8.9),
-or in neither GGUF nor safetensors is left out, and the page says how many.
-Without GPUs it lists GGUF only. Untick **only what these nodes can run** to
-see everything. On a model's page a file too big for the cluster is shown
-without a **Fetch** button, with what it would need.
-
-The **CPU tok/s** column is about how fast one reply would come on the CPU of
-the fastest node whose memory holds the model at Q4_K_M; a model's page gives
-it for each GGUF file by its own size. Every node's agent measures how fast its
-memory reads when it starts (it is in the agent's log as `memory_gbs`), and a
-token on a CPU reads every weight once: the estimate is that speed over the
-model's size — for a model of experts named like `30B-A3B`, its active part.
-On the test cluster it came within 15% of what llama.cpp measured. Several
-replies at once share the reads and each is slower.
-
-**GPU tok/s** is the same on the cards, for the layout this cluster would
-give the model — the fewest cards that hold it, of each class, the fastest of
-those; its tooltip says which ("2× h100-80g, NVLink, vLLM", "2 nodes × 1×
-a100-80g over ib0 (InfiniBand 200 Gb/s), vLLM"). A card's memory bandwidth is
-known from its model name (an H100 SXM and an H100 PCIe differ by half); a card
-not in the table gets no figure. Tensor parallel across a node's cards divides
-what each reads, and adds two all-reduces a layer, short over NVLink and
-longer over PCIe; llama.cpp across cards splits by layer, so the cards take
-turns and a reply is no faster than on one; a pipeline across nodes takes turns
-too, and adds a hop over the fabric for each node. One card's figures were
-measured on the test cluster's RTX 6000; tensor parallel and the fabric are
-from what NCCL is known to take, not measured here.
