Detailed Description

Single-node 16x16 child-order experiment.

The integrated tree uses fanout 256 throughout, with grouped addressing only at leaf parents. This is not a mixed-fanout tree. Grouped metadata occupies 176 bytes; node allocations are 4272 bytes versus 4096 for direct F256. Fresh nodes use direct addressing until a mapped rotation. Current measurements and workload trade-offs are retained in benchmarks/sequence_snapshot.md.
