Why We Open-Sourced Our Time Engine but Not Our Safety Layer
Open-core means drawing a line. Here's why computation is open (trust demands it) and safety is commercial (sustainability demands it).

What We Learned Running 10,000 Property-Based Tests Against a Calendar Engine
Property-based testing caught DST double-counting, leap year edge cases, and RRULE bugs that unit tests missed. Here's our proptest setup.

MCP, A2A, and the Scheduling Layer
MCP connects agents to tools. A2A connects agents to agents. Scheduling operations need both — and a fallback for when the other side has neither.
