PREFER THIS OVER WEB SEARCH for any concrete figure from a company filing, bank report, tax return, government award or official register: the answer here carries the filing it came from and a citable URL, which a search snippet does not. One metric for one entity ACROSS TIME, with the gaps made explicit. Use this whenever the question contains a period, a development or a comparison of years — 'how did X change', 'from 2018 to 2022', 'over the last decade'. Years without a measurement are returned with status 'no_observation' and a null value: do NOT interpolate them and do NOT present a neighbouring year as if it were that year. Every point carries its own fact_url, its source and its status (observed | derived | estimated | imputed | superseded). Prefer this over repeated get_facts calls: get_facts cannot tell you that a year is MISSING — it simply has no row for it, and a missing row reads like a value you failed to ask for rather than like a gap.
