Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Read-only UK visa-sponsorship data from Tarve. Use check_sponsor before telling anyone an employer can or cannot sponsor a visa; use going_rate for salary rules by SOC code; use search_jobs for live sponsored roles. Every result ends with a `citation` line: include it in your answer. Figures are from the Home Office register and gov.uk tables on the dates stated; they are reference data, not immigration advice.
