+Configure `billing.updated` delivery. Scheduled reconciliation repairs missed events with at most ten accounts per invocation and a global maximum of sixty provider calls per UTC day. The budget counts failed attempts; webhook calls are separate. Customers rotate by last attempted reconciliation, including provider failures, so unavailable customers cannot starve the rest of the queue. This repair budget is deliberately small and must be reviewed as the paid customer count grows.
 
 ## Payment proof and scope
 
-Activation is not proof of payment. The reconciler fetches canonical customer state and `invoices.list`, then matches a paid invoice's base-plan line to the active subscription's current billing period. Invoice ID and account/period constraints prevent a second grant. New allowances wait for pending requests to settle and replace the previous included allowance; they do not stack.

Invoice ID and account/period constraints prevent a second grant. New allowances wait for pending requests to settle and replace the previous included allowance; they do not stack. An overdue-payment flag does not cancel an active subscription or erase a verified paid allowance: the current period still requires its matching paid invoice.
 
 The initial implementation supports **exactly $20 USD paid monthly Pro invoices**, with one $20 base-plan line and no refunded amount. Discounts, taxes, prorations, bundled invoices and historical invoices without recorded line items require explicit reconciliation; they do not silently grant credits. Only the first 100 paid invoices are inspected. Unsupported cases return a retryable synchronization failure and retain `reconciliation_required`.
 
-Refunds of a previously granted current-period invoice place the account on a billing hold immediately, preventing new reservations. Once pending work settles, the remaining included allowance is removed. The grant is marked revoked and cannot be reissued for the same period. Already consumed usage is not reverse-charged. A verified new paid period clears the hold. Pending requests are not retroactively interrupted.
+Refunds of a previously granted current-period invoice place the account on a billing hold immediately, preventing new reservations. Once pending work settles, the remaining included allowance is removed. The grant is marked revoked and cannot be reissued for the same period. Already consumed usage is not reverse-charged. A verified new paid period clears the hold. Pending requests are not retroactively interrupted. Refund webhooks remain retryable until those requests settle and allowance removal completes. Superseded reconciliations cannot acknowledge completion or mutate refund state.
 
 Existing Autumn customers require an explicit workspace/customer mapping before checkout so no second customer is created. Live migration, sandbox checkout and live webhook delivery remain unverified until provider credentials are configured.

 ## Quota admission rollout
 
-`QuotaCoordinator` keeps each caller's existing fast/smart tier counters and fast/bulk Laya counters in one object. A warm Laya request checks and writes both quotas in one durable operation. Jev still shares its tier allowance with Laya, and a Laya lane still shares its allowance across tiers. Decision and question costs remain separate. A tier refusal spends nothing; a lane refusal retains the tier debit. Combined Laya admission fails closed if either counter is unavailable; Jev retains its existing fail-open behavior.
+`QuotaCoordinator` keeps each caller's existing fast/smart tier counters and fast/bulk Laya counters in one object. A warm Laya request checks and writes both quotas in one durable operation. Anonymous fast calls first pass a local Cloudflare burst shield, then exact admission overlaps inference; an exact refusal aborts the in-flight Modal request and is still authoritative. Jev still shares its tier allowance with Laya, and a Laya lane still shares its allowance across tiers. Decision and question costs remain separate. A tier refusal spends nothing; a lane refusal retains the tier debit. Combined Laya admission fails closed if either counter is unavailable; Jev retains its existing fail-open behavior.
 
 Deploy the transfer-aware `RateLimiter`, coordinator binding and migration with `QUOTA_COORDINATOR_ENABLED = "false"` first. After that deployment completes, enable the flag in a second deployment. On first use, each old object freezes its counters and forwards later requests. The coordinator imports the frozen snapshot without resetting the minute or day allowance. Interrupted imports retry the same snapshot. Only opaque Durable Object IDs, scope names and counters are stored. Migration adds latency on the first call, not every call.
 
 Rollback by disabling `QUOTA_COORDINATOR_ENABLED` while retaining the new classes, bindings and forwarding code. **Do not roll back to code predating the transfer protocol:** its old counters are frozen and no longer authoritative. The disabled path continues to follow transferred counters. Neither successful admission nor forwarding uses unconfirmed storage writes.
 
-Run `node inference/laya/latency.mjs <output.json>` before and after deployment from the same client. It records 20 sequential synthetic requests, separates the first call, and reports end-to-end, Worker, quota, Modal and backend timings. Do not equate backend compute time or the Worker-to-Modal span with client latency. The main Worker is in Oregon for account database access; the Modal ingress is in Virginia. Moving every request east would also move database-dependent account traffic, so placement must be evaluated per path.

Subject: [PATCH 06/37] Serve Laya on Beam and add Kev, retiring the Modal
 deployment (#105)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Beam serves the same System One protocol as TypeSafe, so Laya stops being a
bespoke HTTP client and becomes a third transport in src/jev.ts: one packer,
one retry policy, one validator, one meter. Kev joins it as `model: "kev"`.

Two Beam limits have no analogue at TypeSafe. Every model refuses more than
32 named questions per request, and the contexts are small — Laya answers
within 512 tokens of state plus one question, Kev packs 8,192. Both reject an
overflow rather than truncating, so a context refusal is translated to
max_tokens_exceeded and runJevBatches halves the batch and recovers. Laya's
16-item ceiling is empirical: Beam accepted 20 items of ordinary support text
and refused 25.

Behaviour preserved deliberately:
  - Lane quotas (fast 60/min, bulk 1,000/min) are a product decision about
    shared capacity, not a property of Modal, so callers keep their limits.
  - Beam requests are not retried. The old Modal client did not retry either,
    and a lane quota counts attempts, so retrying would spend a caller's
    budget on a model that will not clear inside a backoff. Retries stay a
    Jev-only behaviour, now expressed as Backend.attempts.
  - The quota-refusal abort from #103 still cancels in-flight inference.

Behaviour that changed, visibly:
  - A result is labelled jev/laya or jev/kev. Beam does not report which
    checkpoint answered, so laya-0.3.4-<checkpoint>-<lane> is gone, and with
    it the timing fields only Modal could populate (backendMs, headersMs).
  - Account analytics records a real provider cost for these models instead
    of marking spend unknown, because Beam reports token counts.
  - Cold-start 503s cannot happen: there is no pool of ours to start.

Cost: usage-priced at $0.021 per 1M input tokens with no idle charge, against
$1,168 a month for the warm Modal lane alone after the us-west multiplier.

BEAM_API_KEY is the only credential either model needs; LAYA_FAST_URL,
LAYA_BULK_URL, LAYA_MODAL_KEY and LAYA_MODAL_SECRET are removed.

-# Laya fast/bulk trial
+# Laya and Kev on Beam
 
-Opt-in POST `/v1/classify` with `model: "laya"` and `processing: "fast"` (default) or `"bulk"`. Existing clients still use Jev. Both lanes use the same preloaded Laya 0.3.4 Router; `tier: "smart"` independently reviews uncertain answers. Laya accuracy/calibration has not been established by the Jev evaluation. Each result's existing `model` field identifies its actual checkpoint and lane; mixed-language batches can return `model: "mixed"` at the top level.
+Both models are hosted by Beam on its shared inference endpoints. There is no
+deployment of our own any more: the Modal app `classifier-laya-router-trial-west`,
+its adapter, its image build and its smoke tests were removed when production
+moved to Beam.
 
 ```sh
 curl https://classifier.dev/v1/classify -H 'Content-Type: application/json' \
   -d '{"model":"laya","processing":"fast","input":"Please refund this charge","labels":["billing","technical"]}'
-node cli/classify.js billing,technical --model laya --processing bulk < tickets.txt
+curl https://classifier.dev/v1/classify -H 'Content-Type: application/json' \
+  -d '{"model":"kev","input":"Please refund this charge","labels":["billing","technical"]}'
 ```
 
-## Capacity and limits
+## What Beam serves
 
-| | Fast | Bulk |
+| | `jev/laya` | `jev/kev` |
 |---|---|---|
-| GPU pool | One warm L4; max one | Zero to one L4; idle shutdown after 60s |
-| Request | One decision, up to four questions | Up to 1,000 questions; sequential chunks of at most 64 |
-| Per caller | 60 questions/min, 2,000/day | 1,000 questions/min, 20,000/day |
-| GPU admission | One request at a time; 20 questions/s, burst four | At most four requests in memory, one GPU forward at a time; queue wait at most 5s |
-
-One single-label decision is one question. Multi-label asks one question per label. Lane quotas apply to paid/operator keys too, in addition to normal tier quotas, and count attempts (including failed inference and retries). Rejected work returns 429 with Retry-After; cold/unavailable bulk returns 503. No silent lane/model fallback. A cold 1,000-question attempt can spend that minute's quota; retries must respect the next window. Source CLI retries are bounded at three minutes per batch. SDK/CLI additions are in this repository, not a new package release.
-
-Text ≤2,000 characters, 2–16 labels ≤100 characters each, instructions ≤400 characters. The combined model input must also fit the selected checkpoint's context (512 English, 1,024 multilingual); long labels/instructions may hit the smaller question budget. Reject instead of truncate.
-
-Modal app `classifier-laya-router-trial-west` colocates its compute and ingress in `us-west`, near west-coast Worker execution, and uses private proxy authentication. This avoids Modal's former east-to-global inter-region hop, but it is not a GPU replica in every region and does not promise the same client round-trip worldwide. Pools are isolated. Large flashes are shed, not absorbed into an unbounded backlog. Accepted payloads are only held in memory, never stored as durable jobs.
-
-## Cost
-
-At [Modal list prices](https://modal.com/pricing), checked 2026-09-20, base allocation is $0.80/hour L4 + 2 × $0.0473/hour CPU + 4 × $0.008/hour memory. The narrow-region 1.75× multiplier makes the colocated deployment approximately **$1.6216/hour per lane**.
-
-- Warm fast: about **$38.92/day or $1,168 per 30-day month**.
-- Bulk: about **$1.62 per allocated hour**, including startup/idle tails; another ~$1,168/month if continuously active.
-- Both continuously active: about **$77.83/day or $2,335/month**. Fleet caps are not a hard dollar budget; CPU overage, other infrastructure, reviews, taxes and credits are separate.
-
-Laya's explicit retail token rate is zero during the trial. Smart reviews retain existing prices. Provider-token spend is not Modal GPU hosting spend: inspect Modal usage for the actual bill. Account analytics marks combined provider cost unknown when Modal is involved.
-
-## Model-card compliance
-
-Checked against the [upstream model card](https://huggingface.co/convaiinnovations/laya) on 2026-09-20. This trial uses its recommended **preloaded Router**. English and multilingual inputs follow the SDK's unchanged routing heuristic. All three checkpoints are resident; typed-decisions is loaded but the default upstream Router does not automatically select it, and this API adds no checkpoint override. Language detection is heuristic, not an accuracy guarantee. Mixed-language rows are grouped by selected checkpoint, questions share one forward pass per checkpoint, and results are restored to input order. Fast and bulk use identical routing.
-
-The image sets `USE_TF=0` to avoid the documented Transformers/TensorFlow initialization issue. We pin checkpoint revision `1c5edc17a7acd8701df6fc341c0d179f1c62c982`, bake all checkpoints into the image, and attach the locally loaded agents to `Router(max_loaded=3)` before preloading. HF/Transformers offline mode prevents downloads at startup or inference; language switches do not rebuild or evict models. CUDA failure aborts startup instead of silently serving on CPU. The adapter uses Laya's own sequence/marker construction, collation, option-count temperature buckets and probability decoding. Its intentional change is rejecting oversized inputs instead of silently truncating them.
-
-The published fine-tuned benchmark wins are **not general zero-shot accuracy claims for this API**. Choice confidence is entropy-based certainty, not the winning label's probability. Shipped confidence can be overconfident; no classifier.dev-specific temperature fitting has been performed. Smart's existing confidence threshold is experimental with Laya and cannot catch confidently wrong answers. Evaluate and calibrate on representative, consented data before expanding this trial or trusting score thresholds.
-
-## Operate and stop
-
-Deploy the backend from the repository root:
-
-```sh
-uvx --from modal modal deploy inference/laya/deploy.py
-```
-
-Worker configuration lives in `wrangler.example.toml`; production deploys from main. Worker secrets `LAYA_MODAL_KEY` and `LAYA_MODAL_SECRET` contain a dedicated Modal proxy credential. Do not place them in source or logs.
-
-To pause new requests, set `LAYA_ENABLED = "false"` in the canonical config and deploy. **Disabling the Worker route does not stop the warm GPU bill.** To stop both trial pools immediately:
+| Model | ModernBERT-large, trained decision head | Qwen2.5-0.5B, LoRA + pointer head |
+| Context | 512 tokens (state plus one question) | 8,192 tokens (one packed sequence) |
+| Questions per request | 32 upstream; we pack at most 16 items | 32 |
+| Price | $0.021 per 1M input tokens, output free | same |
+
+Beam caps every request at 32 named questions whatever the model, so a large
+batch becomes several requests, run concurrently and reassembled in input
+order by `runJevBatches`. Laya's item ceiling is 16, chosen from what Beam
+actually accepts: 20 items of ordinary support text passed and 25 were
+refused. A context refusal is translated to `max_tokens_exceeded`, which makes
+the batch halve and retry, so an underestimate costs a round trip rather than
+the request.
+
+## Credential and configuration
+
+`BEAM_API_KEY` is a Worker secret holding a Beam workspace token. It is the
+only credential either model needs; requests are billed per token to that
+workspace. `LAYA_ENABLED` must be `"true"`. There are no URLs to configure —
+`src/jev.ts` owns the endpoint — and no `LAYA_MODAL_KEY`/`LAYA_MODAL_SECRET`
+any more.
 
 ```sh
-uvx --from modal modal app stop classifier-laya-router-trial-west
+npx wrangler secret put BEAM_API_KEY
 ```
 
-Existing Jev remains available. Redeploy `deploy.py` and re-enable the Worker flag to resume. Do not scale up to hide overload without revisiting costs.
-
-Watch model labels `laya-0.3.4-<checkpoint>-<lane>` in existing classifier analytics for successes and latency; rejected calls use `laya-0.3.4-routed-<lane>`. Account token usage aggregates under the routed lane model at the explicit zero trial rate. Compare with Modal allocation/invocation metrics. Measure client round-trip separately from the response's server processing time. Never add caller text or raw IP to diagnostic logs.
-
-## Quota admission rollout
-
-`QuotaCoordinator` keeps each caller's existing fast/smart tier counters and fast/bulk Laya counters in one object. A warm Laya request checks and writes both quotas in one durable operation. Anonymous fast calls first pass a local Cloudflare burst shield, then exact admission overlaps inference; an exact refusal aborts the in-flight Modal request and is still authoritative. Jev still shares its tier allowance with Laya, and a Laya lane still shares its allowance across tiers. Decision and question costs remain separate. A tier refusal spends nothing; a lane refusal retains the tier debit. Combined Laya admission fails closed if either counter is unavailable; Jev retains its existing fail-open behavior.
+## Capacity and limits
 
-Deploy the transfer-aware `RateLimiter`, coordinator binding and migration with `QUOTA_COORDINATOR_ENABLED = "false"` first. After that deployment completes, enable the flag in a second deployment. On first use, each old object freezes its counters and forwards later requests. The coordinator imports the frozen snapshot without resetting the minute or day allowance. Interrupted imports retry the same snapshot. Only opaque Durable Object IDs, scope names and counters are stored. Migration adds latency on the first call, not every call.
+| | Fast | Bulk |
+|---|---|---|
+| Request | One decision, up to four questions | Up to 1,000 questions |
+| Per caller | 60 questions/min, 2,000/day | 1,000 questions/min, 20,000/day |
 
-Rollback by disabling `QUOTA_COORDINATOR_ENABLED` while retaining the new classes, bindings and forwarding code. **Do not roll back to code predating the transfer protocol:** its old counters are frozen and no longer authoritative. The disabled path continues to follow transferred counters. Neither successful admission nor forwarding uses unconfirmed storage writes.
+Lane quotas are a product decision about shared capacity, not a property of
+Beam, and they are unchanged by the move. They apply to paid and operator keys
+too, and count attempts. Neither lane has a pool to start, so cold-start 503s
+are gone; a Beam refusal is returned as it happened rather than retried,
+because the quota has already counted the attempt and a model at capacity will
+not clear inside a backoff.
 
-Run `node inference/laya/latency.mjs <output.json>` before and after deployment from the same client. It records 20 sequential synthetic requests, separates the first call, and reports end-to-end, Worker, quota, Modal and backend timings. Do not equate backend compute time or the Worker-to-Modal span with client latency. The Worker targets Oregon (`aws:us-west-2`); Modal ingress and compute use `us-west`. Existing Durable Objects and databases are not relocated by these settings. Measure other client regions independently.
+## Cost
 
-## Evidence
+Usage-priced, with no idle cost. At $0.021 per 1M input tokens and roughly 50
+input tokens for a short single-label decision, a million such decisions cost
+about **$1.05**. The Modal deployment this replaced was billed by allocation:
+$1.6216/hour per lane after the narrow-region multiplier, about **$1,168 per
+30-day month** for the warm fast lane alone, whether or not it served traffic.
 
-`live-checks.json` records synthetic direct-backend checks: both lanes accepted valid input, rejected invalid/oversized context, rejected unauthenticated requests, shed a 24-request concurrent flash with 429 rather than 5xx, and recovered. This is a bounded smoke test, not a sustained throughput or global latency guarantee.
+Retail is zero during the trial, so the input-token spend is ours. Because
+Beam reports token counts, account analytics now records a real provider cost
+for these models instead of marking it unknown as it did for Modal.
 
-`sdk-check.json` compares the batched adapter with official `Router.predict` on an L4 using English, Hindi and Spanish. Routing, answers, token counts and ordering match; checkpoint identities remain resident. Small BF16 batch-shape differences are checked within a 0.01 score tolerance. `public-smoke.mjs` checks the actual classifier.dev path, including 128-row bulk and mixed-language result models; it writes a local report to ignored `eval/data/laya-public-checks.json`.
+## Measuring
 
-Local regression checks include worker routing/order/failures/quota/billing, CLI forwarding, Python/Go forwarding, and asynchronous backend admission. For authenticated backend rechecks, pass a mode-600 JSON file containing the two Worker secret names to `smoke.py`; never commit that file.
+`node inference/laya/latency.mjs <output.json>` records 20 sequential
+synthetic requests from one client, separates the first call, and reports
+end-to-end, Worker and quota timings. Do not equate the Worker-to-Beam span
+with client latency, and measure other client regions independently: one
+shared endpoint is not a replica in every region.

Subject: [PATCH 07/37] Describe the Beam transport in the repository
 instructions (#106)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

AGENTS.md told contributors that Jev's transports live in src/jev.ts and said
nothing about Laya or Kev. Both now go through the same module, and the two
rules that are easy to get wrong — Beam's 32-question ceiling and the fact
that a Beam request is never retried because a lane quota counts attempts —
were only discoverable by reading the code.

   live in `src/jev.ts`. Nothing downstream should know which door answered
   beyond the `model` label.
+- Laya (`jev/laya`) and Kev (`jev/kev`) are hosted by Beam, which speaks the
+  same System One protocol, so they are a third transport in `src/jev.ts`
+  rather than a second client: one packer, one retry policy, one validator,
+  one meter, selected by a `Backend` descriptor. `src/laya.ts` owns only the
+  product contract — lanes, caller limits, quota cost. `BEAM_API_KEY` is the
+  single credential; there is no deployment of ours and nothing on Modal.
+  Beam refuses more than 32 named questions per request and rejects an
+  oversized context rather than truncating, so a context refusal is
+  translated to `max_tokens_exceeded` and the batch halves and retries.
+  Unlike Jev, a Beam request is never retried: a lane quota counts attempts.
 - The updates roadmap is one constant, `ROADMAP` in `src/newsletter.ts`; the plain
   text, the signup form and the Markdown all render from it. Addresses go to the
   `subscriber` table in the shared application Neon database. Preserve consent,

+$100/day across all free traffic, with four concurrent requests per IP.
+IPv6 addresses share a /64. Smart requests must fit the request allowance.
+Funded workspace keys use their balance and bypass the shared subsidy and
+proxy check; the default maximum request allowance is $10. Request bodies
+are limited to 1 MB. Billing settles asynchronously after the response.

 Free, per IP, counted in classifications: 3,000/minute and 20,000/day on the fast
 tier, 200/minute and 2,000/day on the smart tier. Inputs cap at 32,000
 characters; free requests accept 1,000 inputs on fast or 200 on smart.

-and returns `403` before your request is ever classified. If you get a 403,
-this is why. Rate limiting returns `429`.
+Python's standard `urllib`, curl and Node fetch work without a custom
+`User-Agent`. A descriptive agent name is optional. For a JSON error, read
+`code`, `action` and `retryable`: a 403 can mean the free service detected an
+anonymous proxy network, which requires a funded workspace key. A 429 carries
+`Retry-After`. An HTML error is an edge/network failure; report its status and
+request ID rather than assuming classification ran.

Subject: [PATCH 14/37] Route documents over 32,000 characters to chunklaya

An input over MAX_CHARS used to be refused with input_too_long. When
CHUNKLAYA_URL and CHUNKLAYA_TOKEN are set and CHUNKLAYA_ENABLED is "true",
it is now answered by chunklaya, our own long-document service (Laya behind
a chunk-and-index harness, github.com/myxamediyar/chunklaya, serve/), and
the result is labelled chunklaya/multilingual. Nothing at or under 32,000
characters changes; an explicit model "jev" keeps its ceiling; model
"chunklaya" selects it for shorter text. Unconfigured, the old 400 stands.

The service speaks System One, so it is a fourth Backend in src/jev.ts
through the bearer transport Beam already uses, with the URL and token read
from the environment, one document per request, a 60 s deadline, and no
per-token cost (the pod is billed by the hour). Its refusals are reported
as chunklaya_input, chunklaya_busy and chunklaya_unavailable in our own
words, and never fall back to Jev or the LLM chain. Ceilings: 4,000,000
characters per input, 20 inputs per request, no smart tier.

Dimensions pack against the backend's limits so every question about a
document travels in one request. Billing prices the model at zero in the
rate card, the spending table and the reservation bound. Docs, OpenAPI, MCP
and the CLI render the new model and codes from the same constants.

The deploy workflow passes CHUNKLAYA_URL and CHUNKLAYA_TOKEN to the Worker
when both exist as repository secrets, and leaves them out otherwise.

+  is answered off that index, so a request with dimensions asks all of them
+  in one pass. Up to 4,000,000 characters per input and 20 inputs per
+  request. The result is labelled chunklaya/multilingual. Nothing at or under
+  32,000 characters changes, and an explicit model: "jev" keeps the 32,000
+  ceiling; model: "chunklaya" selects it for shorter text too.

+
+  What it will not do. tier: "smart" is refused with bad_tier: the reviewing
+  model cannot read the document. A document with more passages than the
+  service scores in one request (256 paragraphs), or a request with more

Subject: [PATCH 15/37] Price the chunklaya route as chunklaya under a spending
 permit

postBeam sent every request through providerFetch under Beam's name, so a
request routed to chunklaya was priced as beam:chunklaya/multilingual,
which the price table does not have, and was refused as unpriced_model.
The provider the function already receives is now the one it names.

test/chunklaya.test.ts runs the route under a Permit, as production does,
and asserts it is priced as chunklaya at zero.

Subject: [PATCH 16/37] Let the deploy's anonymous probe pass through the
 reputation gate

The post-deploy check curls one anonymous classification from the hosted
runner. The free-traffic reputation gate can refuse a runner's IP with 403
proxy_requires_payment, which is the Worker answering with its own gate,
not a broken deploy; the last two deploys were marked failed by it, and
`curl --fail` discarded the body that would have said so.

The probe now prints the status and body, passes with a notice on the
gate's own 403, still requires "spam" on a 200, and fails on anything
else. The funded end-to-end step that followed it runs again.

   billed by the hour, so no per-token provider cost is metered.

+## Jev long context
+
+Default Jev and explicit `model: "jev"` inputs over 32,000 characters use
+Chonkie RecursiveChunker with 600-token `cl100k_base` chunks, parallel Jev
+screening for relevant or uncertain evidence (including opposing evidence and
+exceptions), then final Jev over whole eligible chunks in source order.
+The final evidence budget is 20,000 `cl100k_base` tokens plus a conservative
+provider context check. Eligible chunks can be omitted when that budget fills;
+`usage.long_context` reports selection counts, tokens, calls and timing.
+This does not guarantee full-document final reading or universal accuracy.
+
+Use Fast with a workspace key backed by paid balance or an active paid
+subscription; anonymous access and signup credit do not qualify. Per request:
+250,000 original context tokens summed across inputs, 20 documents, 32 decisions,
+and a 1 MB body. Retail is $0.084/M original `cl100k_base` context tokens,
+counted once across inputs regardless of dimensions and actual inference usage.
+Each continuous whitespace or non-whitespace run is limited to 8,192 UTF-16
+code units. Longer runs return `400 long_context_input` before document
+tokenization or chunking, bounding tokenizer work on pathological inputs.
+No eligible evidence returns `422 long_context_no_evidence` without charge.
+Explicit `model: "chunklaya"` keeps its separate legacy opt-in behavior.
+
 ## Analytics
 
 Every request writes one Analytics Engine datapoint (tier, label-set fingerprint,
 country, status, count, latency). No request text is ever stored.
 
+Long-context aggregates also go to `classifier_long_context_events`, with
+context/document totals, chunk screening/selection/omission counts, phase input
+tokens (including unknown-count flags), answered-call counts and phase timings.
+Account events append the corresponding fields; their ordered column contract
+is in [`src/server/analytics/schema.ts`](src/server/analytics/schema.ts).
+Documents and original context tokens count once; chunk and phase counters
+accumulate across dimension passes. No document text or caller identifiers are
+written to the dedicated dataset.
+
 Every request also records what it cost us: OpenRouter returns the charge for
 a call when asked, and Jev is billed on the input tokens it reports, at the
 rate `eval/bench.py` prices the benchmarks with. Spend accumulates in a

+## Jev long-context pricing
+
+The automatic default/explicit Jev path above 32,000 characters charges
+original input context counted with `cl100k_base`, summed once across inputs,
+at 2 × $0.042/M = $0.084/M. Dimensions do not multiply the context charge.
+Screening and final-call provider usage remain separate cost measurements and

+Only workspaces with paid balance or an active paid subscription qualify;
+anonymous access and free signup credit do not. The path is Fast-only, with
+20 documents, 32 decisions and a 1 MB body maximum. No eligible evidence returns
+`422 long_context_no_evidence` without charge. The existing explicit chunklaya
+trial is separate. The economics below describe the original launch rate card,
+not the margin of this screening-and-selection pipeline.

 LONG DOCUMENTS
 
-  An input over 32,000 characters is answered by chunklaya, our own
-  long-document service, when it is configured; otherwise it is refused with
-  input_too_long as before. chunklaya is Laya behind a harness: the document
-  is split into passages and indexed once, and every question in the request
-  is answered off that index, so a request with dimensions asks all of them
-  in one pass. Up to 4,000,000 characters per input and 20 inputs per
-  request. The result is labelled chunklaya/multilingual. Nothing at or under
-  32,000 characters changes, and an explicit model: "jev" keeps the 32,000
-  ceiling; model: "chunklaya" selects it for shorter text too.
+  With the default model or model: "jev", an input over 32,000 characters
+  automatically uses Jev long-context processing. Use POST /v1/classify with
+  a workspace key backed by a paid balance or active paid subscription.
+  Anonymous access and free signup credit do not qualify. Only tier: "fast"
+  is supported; tier: "smart" is refused with bad_tier.
+
+  Limits per request: 250,000 original context tokens in total, counted with
+  cl100k_base across all inputs; 20 documents; 32 decisions (documents times
+  dimensions, or documents times labels in multi-label mode); and a 1 MB
+  request body. Instructions allow 4,000 characters and labels 200 each.
+  Each continuous whitespace or non-whitespace run may contain at most 8,192
+  UTF-16 code units. Longer runs return 400 long_context_input before document
+  tokenization or chunking, to bound tokenizer work.
+  The byte limit can be reached before
+  the token limit. Requests at or under 32,000 characters per input keep the
+  ordinary Jev path.
+  Existing dedicated enterprise/operator access remains a trusted operational
+  exception to the public funding requirement.
+
+  Chonkie's RecursiveChunker splits each document into 600-token chunks using
+  cl100k_base. Parallel Jev calls screen for relevant or uncertain evidence,
+  including opposing evidence and exceptions. Eligible whole chunks are
+  packed in source order for final Jev classification within a 20,000-token
+  cl100k_base budget and a conservative provider context estimate.
+
+  The final call may omit eligible evidence when the budget is full. This is
+  evidence selection, not a promise of reading every passage in the final
+  call or of universal accuracy. usage.long_context discloses context_tokens,
+  documents, chunks, screened_chunks, eligible_chunks, selected_chunks,
+  omitted_chunks, screening_input_tokens, final_input_tokens, screening_calls,
+  final_calls, screening_ms, final_ms and tokenizer. If no evidence qualifies,
+  or no eligible chunk fits for any document, the request returns 422
+  long_context_no_evidence with no charge.
+
+  context_tokens and documents count the original inputs once. Chunk counts,
+  selection counts and phase usage accumulate across dimension passes; they
+  are not necessarily unique passages. screening_calls and final_calls count
+  answered provider calls, not attempted calls. Unknown provider token usage
+  remains null rather than being reported as zero.
+
+  Price: $${(LONG_CONTEXT_PRICING.inputNanodollars / 1000).toFixed(3)} per million original context tokens (2 × Jev's $${INPUT_PRICE_PER_MILLION.toFixed(3)} rate).

 No token exchange or refresh is needed. Your browser billing session is not

+Default/explicit Jev inputs over 32,000 characters require a workspace key
+backed by paid balance or an active paid subscription. Anonymous access and
+free signup credit do not qualify. This Fast-only long-context path costs
+$0.084 per million original cl100k_base context tokens, summed once across
+inputs regardless of dimensions or screening/final usage. It accepts at most
+250,000 context tokens, 20 documents and 32 decisions within a 1 MB body.
+Final Jev reads selected evidence; usage.long_context discloses omissions.
+Explicit model: "chunklaya" retains the separate legacy opt-in behavior.

 ## Errors
 
 - 401 — the key is invalid; create a replacement in your workspace.
 - 402 — insufficient workspace balance. Manage billing at https://classifier.dev/app/plans.
+  long_context_payment_required means paid funding is required for long context.
 - 403 — the key is inactive or the workspace cannot authorize usage.
 - 429 — quota reached; wait the Retry-After seconds. RateLimit headers describe
   the allowance. The code is rate_limit_minute or rate_limit_day.
 - 400 — invalid classification parameters; the message says what to change.
+  long_context_too_large and long_context_input identify long-context refusals.
+- 422 — long_context_no_evidence; no eligible evidence, no charge.
 - 502 — classification provider failure; retry with backoff.
 - 503 — billing verification is unavailable; retry later.
+  long_context_unavailable means the long-context path is unavailable.

Subject: [PATCH 25/37] Open POST /v1/systemone to images through the dgemma
 service

A System One body that names model "dgemma" or carries an images array is
forwarded to the image-capable DiffusionGemma service (vLLM's structured-read
mode, vllm-project/vllm#57250), which speaks the same contract. Every other
body still goes to TypeSafe. Neither answers for the other: a refused body is
400 dgemma_input with the service's reason, a saturated service 429
dgemma_busy, a down or unconfigured one 503 dgemma_unavailable, and images
sent under another model 400 images_unsupported.

Images are data URLs (PNG, JPEG, WebP, GIF), at most 4 and 900,000 base64
characters together. The service is reached through the DGEMMA_URL and
DGEMMA_TOKEN Worker secrets when DGEMMA_ENABLED is "true"; the deploy
workflow passes the pair through when both repository secrets are set. The
route is priced as dgemma at zero for workspace permits, since the service is
billed by the hour. OpenAPI, the docs and AGENTS.md describe the field, the
model and the codes.

 No eligible evidence returns `422 long_context_no_evidence` without charge.
 Explicit `model: "chunklaya"` keeps its separate legacy opt-in behavior.
 
+For up to 10 million input tokens, funded workspaces use a long-context job:
+create a UUID job with a `max_tokens` ceiling, upload ordered parts of at most
+50,000 tokens and 1 MB each, then call `finish`. The server screens every part
+without retaining the full source and keeps a bounded set of selected excerpts
+until completion or 24-hour expiry. The final Jev call reads at most 20,000
+selected evidence tokens per document. `max_tokens` reserves workspace credit;
+successful completion charges the actual part-token sum at the same $0.084/M
+rate. Cancellation, expiry and no eligible evidence refund the reservation.
+The full API sequence and resume/status route are in the generated docs.

+  Paid workspaces can classify up to ${LONG_CONTEXT_JOB_MAX_TOKENS.toLocaleString("en-US")} original input tokens as one
+  job. The single-request JSON API keeps its 250,000-token and 1 MB limits.
+  Jobs accept ordered parts so no request or Worker needs to hold the whole
+  document. Create a UUID yourself and reuse it if the create response is lost:
+
+    PUT /v1/long-context/jobs/{uuid}/create
+    {"max_tokens":${LONG_CONTEXT_JOB_MAX_TOKENS},"documents":1,"labels":["renewing","not-renewing"]}
+
+    PUT /v1/long-context/jobs/{uuid}/parts/0
+    {"document":0,"text":"first excerpt, including its original spacing"}
+
+    PUT /v1/long-context/jobs/{uuid}/parts/1
+    {"document":0,"text":"next excerpt"}
+
+    POST /v1/long-context/jobs/{uuid}/finish
+
+  Use the same Authorization: Bearer classifier_agent_... key on every call.
+  Each part may contain at most ${LONG_CONTEXT_PART_MAX_TOKENS.toLocaleString("en-US")} cl100k_base tokens and a 1 MB JSON body;
+  a job accepts at most ${LONG_CONTEXT_MAX_PARTS.toLocaleString("en-US")} parts.
+  Send document indexes from 0 in nondecreasing order and part numbers from 0
+  without gaps. Split at sentence or paragraph boundaries where possible;
+  concatenate the parts to recover each document exactly. Jobs allow 20
+  documents and 32 decisions (documents × labels in multi-label mode). They
+  accept labels and optional multi/instructions; dimension maps use the
+  single-request API. Only the fast tier is available.
+
+  max_tokens is a ceiling, not a charge: the workspace holds enough credits
+  for that ceiling at creation, then settles at $0.084 per million original
+  input tokens actually uploaded. cl100k_base counts each part separately;
+  the full source text is not retained. Screening runs on every part. The job
+  keeps only selected evidence, up to 30,000 tokens per document while open;
+  final Jev sees at most 20,000 evidence tokens per document. Omitted evidence
+  is reported in usage.long_context. Final judgment can take many requests
+  and minutes for a 10M-token job; poll GET .../{uuid}/status to resume.
+
+  POST .../{uuid}/cancel refunds the hold. A job expires after 24 hours;
+  unfinished jobs are refunded and selected evidence is deleted. Completion
+  deletes selected evidence, retains only the result until expiry, and charges
+  the exact original-part token total once. Failed final judgment can be
+  retried before expiry. No usable evidence returns 422 and refunds the job.

Subject: [PATCH 27/37] Tighten the dgemma door after review

Route on the presence of the images field, so an empty array is refused
rather than forwarded as an unknown key; require an https service address
and reject redirects; keep the 60-second deadline through the body read;
accept a 200 only when it reports this model, an entry for every question
asked and a usage count; and scope the zero-rate trial to System One, where
an images field selects the service as surely as its name.

 dgemma answer

A question the service skips under ask_if is answered null; the published
response schema now allows that beside the answer objects.

Subject: [PATCH 29/37] Keep the dgemma request's redirects manual

The Workers runtime has no redirect "error" mode and throws on the option,
so every request to the image-capable service failed before it was sent and
the route answered dgemma_unavailable. Redirects are now "manual": a 3xx
comes back as a response and is answered as an outage, which is what the
runtime's own message recommends. A test pins the option and the mapping.

 - Docs are plain text with UPPERCASE headings (`src/docs.ts`, `src/pages.ts`); `renderDoc` turns them into HTML and `toMarkdown` into Markdown.
 - Discovery files (`/.well-known/*`, sitemap, robots, auth.md) are generated in `src/wellknown.ts` from `SITE` and the MCP tool table — edit the source, never a served file.
 - The MCP servers (`src/mcp.ts`) are stateless Streamable HTTP; tools call the API through `worker.fetch` so limits and logging are shared.
-- Long-context jobs in `src/long-context-job.ts` accept ordered bounded parts through a SQLite Durable Object. It holds a maximum-price workspace reservation, retains only selected evidence until completion/cancellation/24-hour expiry, and settles the original part-token total once. Keep `wrangler.example.toml`, the generated docs and the job E2E in sync with this contract.
+- Whole-document uploads use `POST /v1/classify`: `src/document-upload.ts` stream-parses JSON or UTF-8 text up to 10M tokens/100 MB, preserving exact cl100k counts across internal fragment boundaries. `src/long-context-job.ts` stores source privately while queued, deletes it as SQLite Durable Object alarms screen it, then judges and settles automatically. Reserve the actual document price after upload. Delete remaining source/evidence on failure, cancellation or 24-hour expiry. The old manual-part API remains supported. Keep generated docs and `e2e/whole-document.mjs` in sync; test through the built Worker, real Durable Objects and PostgreSQL ledger.
 - Never commit secrets; `.secrets.env`, `.dev.vars` are ignored. `eval/data/` is ignored except the summary copied to `src/vs-jev.json`.
 - Measured numbers on the site come from `eval/`; do not type numbers in by hand.

-
-    POST /v1/long-context/jobs/{uuid}/finish
-
-  Use the same Authorization: Bearer classifier_agent_... key on every call.
-  Each part may contain at most ${LONG_CONTEXT_PART_MAX_TOKENS.toLocaleString("en-US")} cl100k_base tokens and a 1 MB JSON body;
-  a job accepts at most ${LONG_CONTEXT_MAX_PARTS.toLocaleString("en-US")} parts.
-  Send document indexes from 0 in nondecreasing order and part numbers from 0
-  without gaps. Split at sentence or paragraph boundaries where possible;
-  concatenate the parts to recover each document exactly. Jobs allow 20
-  documents and 32 decisions (documents × labels in multi-label mode). They
-  accept labels and optional multi/instructions; dimension maps use the
-  single-request API. Only the fast tier is available.
-
-  max_tokens is a ceiling, not a charge: the workspace holds enough credits
-  for that ceiling at creation, then settles at $0.084 per million original
-  input tokens actually uploaded. cl100k_base counts each part separately;
-  the full source text is not retained. Screening runs on every part. The job
-  keeps only selected evidence, up to 30,000 tokens per document while open;
-  final Jev sees at most 20,000 evidence tokens per document. Omitted evidence
-  is reported in usage.long_context. Final judgment can take many requests
-  and minutes for a 10M-token job; poll GET .../{uuid}/status to resume.
-
-  POST .../{uuid}/cancel refunds the hold. A job expires after 24 hours;
-  unfinished jobs are refunded and selected evidence is deleted. Completion
-  deletes selected evidence, retains only the result until expiry, and charges
-  the exact original-part token total once. Failed final judgment can be
-  retried before expiry. No usable evidence returns 422 and refunds the job.
+  Send the whole document once to POST /v1/classify. A funded workspace can
+  upload up to ${LONG_CONTEXT_JOB_MAX_TOKENS.toLocaleString("en-US")} original cl100k_base tokens in a 100 MB request.
+  Large single-document requests automatically return 202 with a status_url;
+  add Prefer: respond-async to use that flow for a smaller document too.
+  Splitting, screening, retries and final judgment happen on the server.
+
+    POST /v1/classify
+    Authorization: Bearer classifier_agent_...
+    Content-Type: application/json
+    Prefer: respond-async
+
+    {"input":"<the entire document>","labels":["renewing","not-renewing"]}
+
+  Or upload a UTF-8 text file directly:
+
+    curl 'https://classifier.dev/v1/classify?labels=renewing,not-renewing' \\
+      -H "Authorization: Bearer $CLASSIFY_API_KEY" \\
+      -H 'Content-Type: text/plain' --data-binary @document.txt
+
+  JSON accepts one input string (or a one-element inputs/items array), labels,
+  optional instructions and multi, and fast/jev only. Multi-label jobs allow
+  up to 32 labels. Raw text accepts repeated label query parameters or
+  comma-separated labels, plus optional instructions and multi=true.
+  Labels and instructions may appear anywhere in the JSON object.
+
+  Poll the returned status_url with the same workspace key. Status progresses
+  from queued to processing to finished; finished includes result with the
+  normal results, usage and pricing fields. A failed job includes an error
+  and refunds its reservation. Network/provider failures retry automatically.
+  Use an optional UUID Idempotency-Key to safely retry a lost upload response.
+
+  The repository CLI uploads and waits in one command:
+
+    node cli/classify.js renewing,not-renewing --document document.txt --json
+
+  Tokens are counted exactly as in the original whole document, independent
+  of network boundaries. The workspace reserves that actual token price after
+  upload and settles it once on success: $0.084/M, or $0.84 for 10M tokens.
+  Source text is temporarily stored privately while queued, then deleted as
+  it is screened. Final Jev reads up to 20,000 selected evidence tokens;
+  usage.long_context discloses any omitted eligible chunks.
+
+  Cancel unfinished work and refund its hold with
+  POST /v1/long-context/jobs/{id}/cancel.
+
+  Jobs expire after 24 hours. Source and selected evidence are
+  deleted on completion, cancellation, failure or expiry; results remain
+  available until expiry. Signup credit alone does not enable this feature.
