Chosen because it is the only source that is BOTH keyless AND not barred from commercial use by a free-tier licence - see the licence trap above. Covers earnings/economicevents/dividends/splits/ipo from one origin. TRAPS: (1) it is UNDOCUMENTED - no SLA, no published API terms, and the shape can change without notice, so all parsing is isolated in providers/calendar.ts and every failure falls back to MOCK_CALENDAR rather than 500ing. (2) A default fetch/curl User-Agent gets an EMPTY response - a browser UA is required. (3) Values arrive carrying literal ' ' entities. (4) Akamai fronts it and commonly blocks datacenter IPs, so it can work locally and fail on Railway - /api/health reports which way it went. Get legal sign-off before commercial launch.","envVar":null}]}
