Scrum of Scrums

 * Dependency wall:

Phabricator

 * Quim Discovered a couple of issues with our 'secure' task hiding
 * One is a weekness that could expose private tasks via herald: https://phabricator.wikimedia.org/T493
 * This is getting addressed upstream thanks to chase's proposal to epriestley: https://secure.phabricator.com/T6211
 * Another issue was that the reporter of an issue wasn't actually able to access the maniphest task once it got submitted. https://phabricator.wikimedia.org/T475
 * This is fixed by https://gerrit.wikimedia.org/r/#/c/163753/
 * Still working on https://phabricator.wikimedia.org/T419 and https://phabricator.wikimedia.org/T169
