Per band, the answers, the documents already labelled from the queue for their current answer, those leased to someone, and those available. It hands out nothing, and it is on every plan. A judgment with a non-zero `horizon` has no queue (`invalid_request`): its answers are predictions about what happens next, which nobody can label today. ## OpenAPI ````yaml /api-reference/openapi.yaml get /namespaces/{ns}/judgments/{name}/labelling-queue openapi: 3.1.0 info: title: Vainona API version: '1' license: name: Proprietary identifier: LicenseRef-Proprietary description: | The `/v1` contract from main spec §6. It is locked: changes within `/v1` are additive only, and anything breaking is `/v2`. - **Base URL.** `https://api.vainona.ai/v1`. - **Evolution.** Response objects may gain fields and enums may gain values. Clients must ignore what they do not know. Request objects reject unknown fields. - **Path segments.** Namespace names (`{ns}`) and document ids (`{id}`) may contain `/`. Send it percent-encoded as `%2F`, so that `acme/prod/tenant_123` is `acme%2Fprod%2Ftenant_123`. - **Templates (v1.5).** The judgment routes also take a namespace prefix ending in `/*`, such as `acme%2Fprod%2F*`. A judgment created there is a template: every namespace under the prefix inherits it, including ones created later. The most specific matching prefix wins (§7.7). - **Thresholds are settings (v1.5).** Named thresholds belong to the judgment, not to a version. They are evaluated at read time against the raw fields, so a change applies at once to every answer, with no recompute and no new version (§6.5). - **Entity judgments (entities, E1).** A judgment can read the documents that point at the judged one, through `context.related`, and apply only to documents matching `applies_to` (§6.5.2). Its answers carry a `watermark`, and creating one that runs `on_change` returns a replay estimate of its monthly cost until you confirm (§6.9). - **Referenced documents (entities, E3a).** A relation can also read the one document the judged document points at, through `join: {theirs: "id", mine: "attributes."}`. A change to what the relation renders of that document re-judges the judged documents that point at it and are inside `freshness.fanout.scope`: a fan-out. A large fan-out is a `fanout` job that waits for confirm (§6.5.2, §6.9). - **Idempotency.** Every write operation is idempotent by construction: a retried append adds nothing while its values are still in the array, and a retried upsert or patch sets the same content again (§6.4). `Idempotency-Key` is accepted on every mutating route and, while the node still caches the original response, returns it verbatim. - **Errors.** Every error is the `Error` envelope; the HTTP status follows the code (see each response). - **Rate limits.** Every response carries `X-RateLimit-Limit` and `X-RateLimit-Remaining`; a `rate_limited` response adds `Retry-After`, except a daily allowance that is used up, which says when it renews in `details.resets_at` instead. - **Usage.** Every response that bills carries `usage`. Judging is billed in engine-neutral judgment units: one judgment answered, per started 1,000 tokens of its compiled context and its question together, at least 1 (§9). No response ever carries an engine's price. servers: - url: https://api.vainona.ai/v1 security: - apiKey: [] tags: - name: Namespaces description: Namespaces, their settings and cache warming (§6.2, §6.11). - name: Documents description: Writes, point reads and queries (§6.3 to §6.8). - name: Judgments description: >- Judgment definitions, versions, settings, activation, backfill and template detach (§6.5, §6.9, §7.7). - name: Outcomes and calibration description: | Post what actually happened to judged documents, and read how well answers match it: the calibration report, calibrated answers and threshold recommendations (§6.10).
