Send the file. Receive the smaller copy. Restore every byte.

What it is

PCC takes a file and returns a smaller copy that restores the original. The spine packs a row only when the packed form is strictly shorter. Otherwise it stores the original raw. Decode returns every byte. On the official Silesia 12, the PCC packed size is 51,498,645. gzip-9 on that corpus is larger.

You reach it from the website, from POST /api/compress and POST /api/decompress, from @slidphi/spl-pay-per-suite, and from POST /mcp on this site. The specialist bench is /specialist.

How it works

1. Send the bytes to PCC through your tools.
2. Keep the packed copy.
3. Decompress when you need the original.
4. Compare the restored bytes to the file you sent.

A Rider, when you want a named caller, is minted separately and sent as X-Agent-Rider.

What you receive

You receive a packed file and a decode that restores the original. You receive the official Silesia number 51,498,645 as the PCC stamp. The local engine publishes its own stamp on the TNSSRC booklet.
