weavert-web-research 0.1.0

Shared primitive web research core for WeaveRT framework and product-kit adapters.

weavert-web-research

Framework-level shared web research core used by chat, coding, local-assistant, and devtools adapters. This package is the primitive substrate, not the public owner of the high-level web_research workflow surface.

What this package owns

• normalized source, page, and citation-ready web result structures
• shared public-host and domain-policy enforcement
• a provider registry for deterministic search provider selection, capability metadata, and fallback reporting
• framework-owned research-loop state for budget usage, source and evidence ledgers, provider/freshness events, bounded traces, conflicts, gaps, and stop classification
• a thin backend seam for search, page inspection, and page-local finding
• the default DuckDuckGo HTML plus direct-fetch backend used by first-party adapters
• optional Azure AI Foundry Bing grounding, Google Programmable Search, and Brave Search API provider paths for configured deployments

Provider and freshness behavior

• DuckDuckGo HTML remains the no-credential fallback provider. It reports freshness as unsupported and the core post-filters domain policy.
• Bing grounding is available when FOUNDRY_PROJECT_ENDPOINT, FOUNDRY_MODEL_DEPLOYMENT_NAME, BING_PROJECT_CONNECTION_ID, and AGENT_TOKEN are set. Set WEAVERT_WEB_SEARCH_PROVIDER=bing-grounding to prefer it explicitly. This provider uses Azure AI Foundry Responses API bing_grounding with the configured project connection; it does not call the retired Bing Search API v7 endpoint at api.bing.microsoft.com/v7.0/search.
• Google Programmable Search is available when both GOOGLE_SEARCH_API_KEY and GOOGLE_SEARCH_CX are set. Set WEAVERT_WEB_SEARCH_PROVIDER=google-search to prefer it explicitly.
• Brave Search is available when BRAVE_SEARCH_API_KEY or WEAVERT_BRAVE_SEARCH_API_KEY is set. Set WEAVERT_WEB_SEARCH_PROVIDER=brave-search to prefer it explicitly.
• freshness_days, recency_days, or compact freshness.days map to provider freshness only when the selected provider supports it. Otherwise results include freshness_scope.status="unsupported".
• Bing grounding returns grounding citations rather than raw search API records. The adapter maps result count and supported freshness hints into the Foundry grounding request, accepts only stable public http or https URLs as candidate results, and leaves framework-side public-host, allowed-domain, and blocked-domain validation authoritative.
• Google and Brave domain allow/block constraints are mapped with site: and -site: query operators, then revalidated by the shared core.
• Google freshness maps to dateRestrict; Brave freshness maps to Brave's freshness parameter; Bing grounding freshness maps to the supported Foundry freshness values for 1, 7, and 30 day windows. These are reported as provider-side freshness enforcement when mapped, but final URL policy remains enforced by the shared core.
• When Bing grounding, Google, and Brave are all configured, the default registry tries Bing grounding first, then Google, then Brave, then DuckDuckGo HTML. Explicit WEAVERT_WEB_SEARCH_PROVIDER selection still takes precedence and falls back through the remaining configured providers when fallback is allowed.
• Default tests use deterministic FixtureWebResearchProvider instances and mocked provider responses. Live-provider smoke checks are opt-in by setting provider credentials and running targeted tests outside the default deterministic suite.
• Profile-aware loops attach bounded source-quality metadata such as source class, duplicate cluster, profile-priority signals, freshness signals, and provider metadata. These signals explain selection and evaluation; they are not independent proof of factual truth.
• Ledger-bound claim annotations may be merged by higher-level kits only when they reference an existing source, page, or evidence handle. Rule-derived dates, versions, prices, numbers, source-type hints, and duplicate signals are auxiliary diagnostics, not truth validators.

Higher-level packages such as weavert-kit-common-web-research compose this core through their package adapters. The shared common web research kit owns the public web_research tool and its package-owned delegated worker.
