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.
