Structure-aware, byte-exact, never-worse: structured data, byte-exact, and where it falls back
The difference between entropy-coding compressors (gzip, brotli, xz) and structure-aware compression. On data with discoverable structure the win can be large; on incompressible data Pedulli falls back to identity with a +1 byte floor. Every restore is byte-exact and reproducible on request.

How Pedulli's best-of-N racing dispatcher actually works
Inside the router: how a file is routed by magic-bytes + extension + an entropy probe, how parallel codecs race and pick the smallest output, and the 1-byte container format that guarantees no expansion.

The +1 byte no-expansion floor - and why every codec should have one
Measured on 1 MiB of random bytes: gzip adds ~341 B of framing, brotli ~5 B, xz ~424 B, 7-Zip ~658 B. Pedulli adds 1 byte. A guarantee about Pedulli's own output - never-worse than input + 1 byte - and the design choice behind it.
