Dudu-0223 8395722db5 fix: address codex review findings on web seam
- search providers (exa/perplexity/deepseek): map the parsed response
  INSIDE the parse try, so a well-formed body of the wrong shape surfaces
  as WEB_PROVIDER_ERROR instead of escaping as a raw TypeError; a WebError
  the mapper throws on purpose is re-thrown untouched
- web-fetch-local: validate numeric limits at plugin construction (positive
  finite caps; non-negative integer maxRedirects) rather than constructing a
  provider with nonsensical values
- web-fetch-local: enforce the redirect budget BEFORE resolving each hop, so
  maxRedirects:N follows exactly N redirects and an over-limit hop reports
  "exceeded the maximum" rather than misdiagnosing a cross-origin block
- drop the stale dsh-tool-web/search and /fetch path aliases (the package no
  longer declares those subpath exports)
- strip trailing EOF blank lines flagged by git diff --check

Each fix carries a regression test.

@deepseek-ai/dsh-web-search-perplexity

A Perplexity-backed WebSearchProvider for the harness web capability seam (ctx.web). It calls Perplexity's OpenAI-compatible POST /chat/completions endpoint and maps the generated answer plus citations into the seam's normalized WebSearchResult.

This is an implementation package: it registers a provider into ctx.web, it does not own the key and it does not register a model-facing tool. Like @deepseek-ai/dsh-llm-deepseek, it is a function/namespace plugin (inject: ['web']). The OpenAI-compatible wire shape is a provider-private detail — it does not make this provider depend on ctx.llm.

Config

Key Default Meaning
apiKey $PERPLEXITY_API_KEY Perplexity API key. Empty/absent → provider status() reports missing-credential.
baseURL https://api.perplexity.ai Endpoint base; /chat/completions is appended. An unparseable value makes status() report misconfigured.
model sonar Search model name.
- id: web-search-perplexity
  name: '@deepseek-ai/dsh-web-search-perplexity'
  config:
    apiKey: !!js process.env.PERPLEXITY_API_KEY

Mapping

contentchoices[0].message.content (the generated answer). sources[] prefers the structured search_results[] (url, title, snippet, publishedAtdate), falling back to the URL-only citations[] array only when search_results is absent — those sources carry just a url, which is why title/snippet/publishedAt are optional on the seam. Provider failures surface as WebError WEB_PROVIDER_ERROR; an aborted request surfaces as WEB_ABORTED. Perplexity has no result-count control, so maxResults is enforced by the seam (truncating sources[] and setting truncated).
