 - **The SBIR topic `agency` filter is documented as organization-resolved.** It rolls up the hierarchy (`HHS` includes NIH topics) and falls back to the raw agency text only for a token that does not resolve; the docs said it never resolved.
 - **API errors now carry the server's reason when it is nested under `detail`.** A 403 or other non-2xx response the SDK had no dedicated variant for kept a top-level `detail`, `message` or `error` string, but a structured body such as a plan gate's `{"detail": {"error": "...", "code": "tier_required"}}` left `Error::Api`'s `message` at `API request failed with status 403`, so a caller refused for a plan-gated filter couldn't tell why. The message is now the API's own explanation (`tango: API error (status 403): The 'psc' filter requires a Small plan or higher.`), and the parsed body stays on `response`. When a body carries several of these keys, `error` now wins over `message` and `detail`, matching the Python SDK. Non-JSON bodies, such as a proxy's 502 page, keep the old message.

 Official, async-first Rust SDK for the [Tango API](https://tango.makegov.com) — federal contracts, IDVs, entities, opportunities, grants, vehicles, and more, with dynamic response shaping so you fetch only the fields you need.
 
-> **Pre-1.0 — v0.2.0.** The resource surface now tracks the sibling SDKs endpoint for endpoint, but the public API may still shift before v1.0.0. Pin to a specific version if you depend on this in production.

 The sibling SDKs are `tango-python`, `tango-node` and `tango-go`. This Rust port ships the full transport, error model, retry / rate-limit handling, webhook signing (in the separate `tango-webhooks` crate), and the resource-method surface. Same `0.x → 1.0` graduation logic as Go: the transport and types are stable; the surface stabilizes once it has been verified against the live API alongside the siblings.
