 - **Citation-fallback sources are URL-only** — when Perplexity omits structured `search_results[]`, sources carry no `title`/`snippet`/`publishedAt`, so the tool renders bare hostname labels.
 - **Over-returned sources still cost tokens and latency** — with no result-count control on the wire, `maxResults` is enforced only post-hoc by seam truncation.
-- **Only `model`/`maxTokens`/`searchRecency` are exposed** — Perplexity's other search controls (domain filters, `web_search_options` context size, images) wait on provider-neutral seam fields ([seam Agent Note](../../../.agents/notes/implemented/architecture/2026-06-24-web-capability-seam.md)).

 - **Abort classification is error-shape-based** — only a `DOMException` named `AbortError` maps to `WEB_ABORTED`; an abort carrying a custom reason (e.g. `dsh-timeout`'s `TimeoutReason`) surfaces as `WEB_PROVIDER_ERROR`.

 - **引用回退源只含 URL**：Perplexity 省略结构化 `search_results[]` 时，源不含 `title`／`snippet`／`publishedAt`，因此工具只渲染纯主机名标签。
 - **超量返回的来源仍会增加 token 消耗和延迟**：协议没有结果数量控制，`maxResults` 只能由 seam 在事后截断。
