feat(audio): async audio generation job API across neuron, cortex and router (#382 )

Music renders take seconds to minutes, so /v1/audio/generations is a job API rather than a request/response endpoint: POST /v1/audio/generations submit -> 202 + job GET /v1/audio/generations the caller's jobs GET /v1/audio/generations/{id} poll GET /v1/audio/generations/{id}/content the rendered audio DELETE /v1/audio/generations/{id} cancel cortex owns the job. It validates against the model's advertised limits, reserves budget, queues the job behind a fleet-wide concurrency bound, and dispatches it to a neuron serving the model. A busy model (429/503) is waited on without spending an attempt; a failing node is retried up to max_attempts. Records and audio are written under [audio_jobs] dir, so the job list and finished results survive a restart, and unfinished jobs are re-queued (with a fresh reservation) at startup. Finished jobs expire after retention_hours. Jobs belong to the submitting account; anonymous jobs are reachable by id only and never listed. neuron renders one generation per call, synchronously, on the same path. The response body is the audio and the metadata rides in the x-helexa-audio-result header, so long songs need no base64 envelope. The harness seam (CandleHarness::audio_generation) answers wrong_modality or model_not_found until the ACE-Step engine lands (#383). The router dispatches submissions by capacity like any inference call, and answers job calls by asking each cortex until one does not 404, since a job id carries no hint of its cortex. Listings merge across cortexes. Model limits (duration range, vocals, sample rate, max steps) are declared per catalogue profile ([models.audio]) and advertised in /v1/models, so clients can build their forms from them. Metering settles audio-seconds through a placeholder token bridge until #386 moves rates into the database. helexa-bench chat scenarios skip audio models, and the cortex unit gains StateDirectory=cortex for the job store.

+
+## 2026-09-29 addendum: System-One decisions (Laya, epic #333)
+
+A third modality beside text and images: **typed decisions**.
+`convaiinnovations/laya` is a 421M non-autoregressive decision model, a
+ModernBERT encoder plus an option-scoring head. It answers `choice` /
+`score` / `noul` questions over a *state* in one encoder forward, with
+calibrated probabilities, on the TypeSafe Jev wire protocol:
+`POST /v1/systemone`. It never generates text. Resident on quadbrat's
+3060 since #351, replacing the Qwen3-1.7B pre-warm.
+
+**The reference is the `laya` pip SDK** (`common.py`, `agent.py`,
+`router.py`, `serve.py`), **not** the `rl_common.py` in the model repo,
+which has diverged. Fixtures recorded from SDK 0.3.21 at model revision
+`55cf4c4e` live in `crates/neuron/src/harness/testdata/laya/`:
+- `reference.json`: 28 cases, f32 CPU.
+- `reference_cuda_bf16.json`: the SDK's own GPU bf16 run, the envelope
+  our bf16 is judged against.
+- `lang_corpus.json`: 924 detector cases.
+
+Recorders are `script/laya-reference.py` and `script/laya-lang-reference.py`.
+
+**Where it lives:**
+- `cortex-core/src/decisions.rs`: wire types, and `Json`, an
+  order-preserving, correctly rounded, `json.loads`-compatible value.
+  Request data must not go through `serde_json::Value`: the workspace
+  has no `preserve_order`, and without `float_roundtrip` serde_json
+  misreads floats (`…445` → `…443`). Key order changes token ids and
+  what the language detector reads.
+- `neuron/src/harness/decision/`: question validation, sequence
+  assembly under every budget rule, calibration in numpy's float32
+  order, answer shaping, and `route.rs` (checkpoint choice, ported from
+  upstream `Router._route`, reason strings included).
+- `neuron/src/harness/lang_detect.rs`: the script/language detector.
+  Python-semantics Unicode classes: `[^\W\d_]` never matches a combining
+  mark.
+- `neuron/src/harness/arch/laya/`: the engine. The ModernBERT backbone
+  is **vendored**, because candle's only runs in f32.
+- `decision_model.rs`, plus `CandleHarness::systemone` in `candle.rs`.
+
+**One repo, three checkpoints:** English at the root, `multilingual/`
+and `typed-decisions/`, all resident. Precedence: a `model` pin (a
+checkpoint name, an alias, or a published id such as
+`convaiinnovations/laya-multilingual`), else the detected script and
+language, else English. The English checkpoint collapses outside
+English (Khmer: 0.000 accuracy at 0.952 confidence upstream), so
+language routing is correctness, not polish.
+
+**Surface semantics:**
+- On this endpoint only, a missing or unknown `model` resolves to
+  **`helexa/one`** at every hop, because Jev clients send their own
+  service's name (`jev-1`).
+- The body is never rewritten, since `model` may be a checkpoint pin;
+  the routed model travels in `x-helexa-decision-model`.
+- Metering follows Jev: **input tokens only**. That is the sum of
+  encoded sequence lengths, and the state is encoded once per question.
+  Reserved as questions × `max_len`, settled to `usage.input_tokens`,
+  priced at $0.042/M.
+- Errors carry the #63 envelope plus FastAPI's `detail`.
+
+**GPU performance (3060, #337).** Laya needs the ampere flavour's
+`flash-attn` (enabled in #350; `NEURON_FLASH_ATTN=0` rolls back). What
+the profile found:
+- candle's `LayerNorm` only fuses when a bias exists, and ModernBERT's
+  norms have none: six kernels per norm, about 25% of GPU time. Fixed
+  with an explicit zero bias.
+- Mask add and scale over the full score tensor. Elided when nothing is
+  masked; scale folded into q.
+- Eager attention replaced by `flash_attn_varlen_windowed` over an
+  unpadded pack (sliding layers ±64).
+
+Measured, bf16: 36 ms for one question over a 512-token state (reference
+39), 32 seq/s batched. Live: 10.6 ms median at the neuron over the mesh.
+bf16 drift is autocast-style: residual, norms and attention scores stay
+in f32. Beyond that, per-case drift is chaotic; judge it by
+mean-vs-reference-envelope, not single cases.
+
+**Validation:**
+- `script/validate-decision.py <url>` replays the corpus against any
+  hop: checkpoint and usage exact, answers except on reference
+  near-ties, probabilities within a bf16 tolerance.
+- The public edge is `https://helexa.ai/v1/systemone`. It is rate-limited
+  (10 r/min per IP), so replay against the router (gallumbits:8088).
+  Probing the public names has network constraints; see
+  `doc/infra/edge-ingress.md` in the private helexa/security repo.
+
+**Sharp edges:**
+- **rustingface#6:** a neuron cold load of anything rf.internal hasn't
+  cached fails on a 503 to hf-hub's bounded-range size probe. A Laya
+  family member then loads *without* that checkpoint, logged but
+  silent. Warm with full GETs, then reload.
+- helexa-bench chat scenarios must gate on `serves_chat()`, which
+  excludes both `image` and `decision` models.
+
+**Open:** #353 (revision pinning, per-language temperatures, fetch
+retries, a bench `decision:` scenario, a dashboard panel,
+micro-batching); #342 (serving fine-tuned checkpoints); #352 (Z-Image on
+the ampere flash build, unrelated to Laya but enabled by the same
+flavour change).

+//! OpenAI has no music endpoint, so this is a helexa extension. It follows

+//! a song takes seconds to minutes to render, so the public API is a job API.
+//!
+//! - `POST   /v1/audio/generations`               submit → `202` + [`AudioJob`]
+//! - `GET    /v1/audio/generations`               list the caller's jobs
+//! - `GET    /v1/audio/generations/{id}`          poll → [`AudioJob`]
+//! - `GET    /v1/audio/generations/{id}/content`  the rendered audio bytes
+//! - `DELETE /v1/audio/generations/{id}`          cancel
+//!
+//! cortex owns the job record. A neuron renders exactly one generation per
+//! dispatch, synchronously, on `POST /v1/audio/generations`: the response
+//! body is the audio (`audio/wav`) and the result metadata travels in the
+//! [`RESULT_HEADER`] header as JSON ([`NeuronAudioResult`]). Keeping the

+//! Async music / audio generation jobs (#382).
+//!
+//! A render takes seconds to minutes, so the public surface is a job API
+//! (see [`cortex_core::audio`] for the routes). cortex owns the job: it
+//! records it, queues it, dispatches it to a neuron serving the model, keeps
+//! the rendered audio, and meters it. A neuron renders one generation per
+//! dispatch, synchronously, and knows nothing about jobs.
+//!
+//! Records and audio are written under `[audio_jobs] dir`, so the job list
+//! and finished results survive a cortex restart. Jobs that were queued or
+//! running when cortex stopped are re-queued at startup. A job whose neuron
+//! fails is retried on whatever node the router picks next, up to
+//! `max_attempts`; a neuron that is merely busy (429/503) is waited on, up
+//! to `queue_timeout_secs`, without spending an attempt.
+//!
+//! Ownership: a job belongs to the account that submitted it, and only that
+//! account can see, fetch or cancel it. Anonymous jobs (no principal) are
+//! reachable by id alone — the id is an unguessable capability — and never
+//! appear in a listing.

+//! Async audio generation jobs through the router (#382).
+//!
+//! Submitting a job is ordinary capacity dispatch: the router picks a cortex
+//! that serves the model and forwards the body, and that cortex owns the job
+//! from then on. Every later call names only a job id, which carries no hint
+//! of its cortex, so those calls are asked of each cortex in turn and the
+//! first answer that is not `404` wins. Listing merges every cortex's list.
+//!
+//! Ownership is enforced by the cortex holding the job; the router forwards
+//! the caller's bearer unchanged, exactly as for inference.

+title: Using decisions
+sidebar_label: Decisions
+description: Typed questions over text or JSON, answered with calibrated probabilities — the System-One endpoint and its playground.
+---
+
+# Using decisions
+
+A **decision model** answers typed questions about a piece of text or
+JSON — the *state* — in a single pass. It never generates text: every
+answer is a probability distribution over options you define in the
+request. That makes it fast (tens of milliseconds), cheap, and
+predictable enough to put in front of a workflow: routing a ticket,
+screening a message, deciding whether to escalate.
+
+Try it without writing code in [the playground](/playground).
+
+The endpoint is `POST https://helexa.ai/v1/systemone`, and it speaks the
+TypeSafe Jev protocol, so existing Jev clients work unchanged.
+
+## A request
+
+```json
+{
+  "state": "I was charged twice this month and want the duplicate refunded.",
+  "questions": {
+    "queue": {
+      "type": "choice",
+      "instructions": "Which team should handle this ticket?",
+      "criteria": {
+        "billing": "payments, invoices and refunds",
+        "technical": "login, bugs and app issues",
+        "other": "anything else"
+      }
+    },
+    "urgency": {
+      "type": "score",
+      "instructions": "How urgent is this ticket?",
+      "criteria": ["low", "normal", "high", "critical"]
+    },
+    "refund": {
+      "type": "noul",
+      "instructions": "Is the customer asking for money back?"
+    }
+  }
+}
+```
+
+Every question over the same state is answered in the same request, and
+`answers` comes back in the order you asked.
+
+## The three question types
+
+| Type | Asks | `criteria` | Answer |
+|---|---|---|---|
+| `noul` | Is a statement true? | optional `{"true": …, "false": …}` descriptions | `noul`: P(true) |
+| `score` | Where does this fall on a scale? | a list of levels, lowest first | `score`: the expected level, which can fall between two |
+| `choice` | Which of these options? | an object of `label: description`, or a list of labels | `choice`: the most likely label |
+
+A `noul` question also takes `labels`, e.g. `{"true": "late", "false":
+"on time"}`, to name its two answers.
+
+Every answer carries `probabilities` for each option (choice and score),
+plus two confidence numbers that are **not** interchangeable:
+
+- `answer_confidence` is the probability of the chosen answer. It is the
+  calibrated number: set thresholds on this one.
+- `confidence` is how decided the whole distribution is — one minus the
+  normalised entropy for choice and score, the larger probability for
+  noul. It is not comparable across question types.
+
+## The state
+
+- A **string** is read as written.
+- An **object** is serialised as JSON, keys in the order you wrote them.
+- A **list** is read as a conversation. When it is too long, it is
+  trimmed from the start, so the newest turns survive.
+
+Order matters: the model reads question ids, option labels and object
+keys in the order they arrive.
+
+## Languages and checkpoints
+
+The model family has three checkpoints: English, multilingual and
+typed-decisions. By default the service picks one from the language of
+the state — Hindi, Japanese, Arabic, Russian and non-English Latin text
+all go to the multilingual checkpoint — and the response's `routing`
+block says which answered and why.
+
+Send `"model": "multilingual"` (or `english`, `typed-decisions`) to pin
+one. `helexa/one` is the class alias, and any model name the service
+doesn't recognise — such as a Jev client's own — falls back to it.
+
+## Limits and budgets
+
+- At most 64 questions, 100 options per choice, 32 levels per score,
+  and 512 options across the request.
+- The state is at most 50,000 characters.
+- Each question and its options share a token budget with the state.
+  Many or long options squeeze each other; if they are cut to the same
+  tokens, `usage.options` says so, and the model can no longer tell
+  them apart.
+
+## Metering
+
+Decisions are metered in **input tokens**, reported in
+`usage.input_tokens`; `output_tokens` is always zero. Each question is
+encoded together with the state, so every extra question over a long
+state costs that state again.
+
+## Errors
+
+Errors use the same envelope as the rest of the API, plus a `detail`
+string with the exact reason:
+
+- `400` / `422`: the request needs fixing. `detail` names the question.
+- `413`: over one of the limits above.
+- `429` / `503`: slow down or retry; honour `Retry-After`. The public
+  endpoint allows 10 requests a minute from each address without an API
+  key.
