BlackboardLayout

Remarks

The naive blackboard is a Dictionary<string, object>, and it is wrong in four ways at once — a hash per read, a box per value, an allocation per write of a struct, and no cheap way to observe a key. A layout is authored once and compiled; an instance is then a byte range, a key reference is a UInt16, and a read is a span slice.

Immutable and shareable: a thousand agents on one tree share one layout and hold one Blackboard each. Build one with BlackboardLayoutBuilder.
