fix(lifecycle): ground company research in substantive evidence

 The client makes one homepage request with a 15-second total deadline and 2 MiB response limit. The scraper has a shorter 10-second work budget and one active capture; busy requests fail without queueing. The existing HTML extractor produces the same bounded evidence schema. The service returns the requested source and actual final browser URL; the client validates both and checks public input/final hostnames. The browser service owns remote navigation and subresource checks. This service boundary does not provide the direct fetcher's DNS-pinned transport guarantees, and capture is not proof of employment or company ownership. See [the scraper deployment](../../deployments/company-scraper/README.md) for its pinned source, patch, and verification commands.
 
 Client capture logs contain provider, outcome, status, and byte count where available (direct capture also identifies the fixed requested path). They exclude page text, company URLs, and credentials. Keep the default provider until the self-hosted service is deployed and authenticated capture is verified. Browser rendering does not include Firecrawl Cloud's advanced anti-bot engine.
+
+Evidence extraction excludes navigation, menu, footer, and header-list subtrees, including nested text. Snippets prefer paragraphs and product lists in `<main>`, falling back to the remaining document when main has no eligible snippets. Title, hero headings and paragraphs, and description metadata remain available. Empty captured pages are omitted from model input. The enrichment prompt requires substantive support for capability claims and explicit first-party attribution for retained promotional rankings or assertions. This improves evidence selection; valid source references alone do not prove a generated claim is true.
