Not a dry run of evaluate. Replays a local structure and its base over the decision's reviewed and seeded cases in the key's environment (a test key previews against test cases only), and returns fixes, breaks, the action mix and an evidence label. The result must decide outcomes (bands, rules or match): a value result is 400 OUTCOMES_INVALID. Each case reuses the answers its evaluation stored for questions whose hash is unchanged; changed and new questions are asked the way evaluate asks them (each question's `reads`, grouped into System One calls), so a preview costs what evaluating the changed questions would. Writes an eval run only: never an evaluation, never traffic, never acceptance. A preview does not register the candidate: before evaluating by its structure hash, register it with POST /v1/decisions/{decision_id}/structures (or send the structure inline on evaluate once). Holdout cases it lists individually (fixes and breaks) are burned (they count as training from then on); unlisted holdout cases are only scored. `evidence.by_split.holdout.holdout_uses` counts preview runs that scored held-out cases, not burns. The base, in order: the base of `suggestion_id` when it is sent (then `base` is ignored), else `base`, else the version serving primary traffic in the key's environment, else the newest one seeded there, else none. With `suggestion_id`, `hashes_match` says whether the structure is that suggestion's candidate; another environment's suggestion is 404. The evidence replays only cases with an outcome from the owner, reviewers or seeds; the action mix replays a sample of the environment's recent primary traffic. For questions the candidate changes, `before` is a fresh re-run of the base question (the fair baseline), so engine nondeterminism can move it between previews. `noise_rate` measures outcome flips from that re-run against the stored answers, not value drift. Holdout burns and use counts are per environment, and a test key's preview neither reads nor fills the shared cache of engine answers. A decision nothing was registered, evaluated or seeded under is 404. ## OpenAPI ````yaml /openapi.json post /v1/decisions/{decision_id}/previews openapi: 3.1.0 info: title: Moonbounce Decisions API version: 0.0.0 description: >- Moonbounce decisions: evaluate an item's state against a decision structure (System One questions, attributes you supply and aggregations over both), record feedback and seed examples, review a ranked queue, and improve the structure through suggestions that ship as code diffs, each with a preview (backtest) and an evidence label. **Authentication.** Send an API key as `Authorization: Bearer ` on every operation except `GET /health` and `POST /v1/structures/hash`. Call the API from a server, never a browser: a key must not reach one, and the API sends no CORS headers. A key belongs to one organization and one environment: production, or test for a key with the `env:test` permission. Test traffic never counts as production traffic. **Requests.** JSON bodies (`Content-Type: application/json`) of at most 1 MB, parsed strictly: duplicate keys, lone surrogates, integers outside ±(2^53 - 1), `__proto__` keys, U+0000 and nesting deeper than 64 are a 400. **Retries.** Send an `Idempotency-Key` on every POST under /v1 that takes one (all but `POST /v1/structures/hash`). Keep it for the request's retries. The same key with the same request returns the first stored result, marked `Idempotent-Replayed: true`, for 24 hours (410 if that result was since deleted); with another request it is 422 IDEMPOTENCY_KEY_REUSED. Keys are scoped to the organization and environment across every operation, so use a fresh key per request. A request that failed before its result was stored runs again when retried. 429 and 503 under /v1 may carry `Retry-After` (seconds); a daily QUOTA_EXCEEDED cap instead names its reset time. **Errors.** Every error under /v1 is `{"error": {"type", "message", "reason"?, "param"?, "details"?}}` (ErrorBody); `GET /health` answers its own shape. Every response carries a `Request-Id` header. Rate limits apply per key, and per client IP for requests without a valid key; a 429 RATE_LIMITED carries `Retry-After`. servers: - url: https://api.moonbounce.ai description: Production security: [] paths: /v1/decisions/{decision_id}/previews: post: tags: - suggestions summary: Preview a structure change against past feedback description: >- Replays a structure change over past cases with feedback: it spends engine calls, stores a run, and burns the held-out cases it lists.
