PS4 PT Decrypted, PlayStation 4 Testkit Running PT Game Backup!
Following EPEEN's scene release, Installing PKG's and the PS4 Backup DevKit PoC, today PlayStation 4 developer @zecoxao announced on Twitter that the interactive teaser for the game Silent Hills called P.T. (Playable Teaser) has been decrypted and the game backup is playable on a PS4 Testkit console! 
Credit also goes to AnB69947709 for providing the dumps and files and to PixelButts for testing the game backup on his PlayStation 4 development unit, with a torrent below for PS4 developers interested in sorting out how to load it on a retail console.
Here's a little background about the game from Wikipedia, to quote:
"P.T. (short for "playable teaser"), is a first-person psychological survival horror video game developed by Kojima Productions, under the pseudonym "7780s Studio", and published by Konami. The game was directed and designed by Hideo Kojima, in collaboration with film director Guillermo Del Toro.
Released for the PlayStation 4 on 12 August 2014 as a free download on the PlayStation Network, P.T. served primarily as an interactive teaser for the game Silent Hills, a cancelled installment in the Silent Hill series. After the cancellation, Konami removed P.T. from the PlayStation Store and eliminated re-installing the game, a decision that later spawned criticism and fan efforts to allow...

He also shared a Precompiled VitaDump kernel plugin tested on taiHENkaku Beta 4 which should dump kernel modules to ux0:/dump and with PS4 developers the NID for sceAppInstUtilAppInstallPkg: bpLyMf0oVwQ in response to @flatz's recent update.
Those who have been in the scene since at least the early PlayStation 3 days will recall Netkas and flukes1 first added Peek and Poke support to the PS3, which was then supported in countless PS3 Custom Firmware releases.
