On Overwatch Penance - Please Clarify

The descriptor for the penance is unclear.

Your community is guessing about whether the following affects the clear condition:

Toughness damage - Do we fail if we take a hit at 100% toughness?
Hound damage - Do we fail if a teammate next to us gets hit by a hound and chips our healthbar by 1 damage?
Trapper damage - Do we fail if we get trapped?
Mutant damage - Do we fail if pummeled by a mutant?

Additionally, is this penance obtainable if you join an in-progress game via quickplay? Is this penance obtainable if you disconnect from a game?
In other words: in your effort to counter the abuse of the “ALT-F4 cheese,” have you made the penance harder to obtain than it was before?

I am loving your game, however.

no

most likley

you can mitigate first hit with 100% toughness, second will drop yor health.

no and no, you gotta do it all the way
