Past-date evidence, with its clocks shown

the proof you can drive yourself

Updated: live

Pick a past date to ask the live API for its historical records. The credibility panel applies its knowability clock; the attention panel reconstructs events by their historical event date and may include events detected later. The universe counts names listed then, including names since delisted. Read each panel's time basis before treating it as something a subscriber could have seen that morning.

For credibility, the two-tier knowable clock uses EVENT when the period's real public clock was captured (the call was held, or the transcript was published — whichever is later). MODELED means no clock was captured, so the point only counts as knowable once its label month has completed. Result filings are never used as a clock for call-derived content, because filings usually come first — that is the leak direction.
