Frozen public photographic median
Previously sealed H2 holdout
What is new here
Recursive logical geography
Every image region has a stable Base-4 ancestry. The fractal supplies locality and addressability, not magical compression.
Local reversible encoding
Each block tries nine reversible pixel transforms before compression and stores a decode-aware winner.
Exact access + fallback
Requested crops touch only relevant blocks, outputs are hash-verified, and a conventional tile pyramid remains legal when FIC loses.
