fep-1b12

> There is a difference between Shoot and FEP-1b12. In FEP-1b12, `attributedTo` is a collection, while in Shoot it is a single actor.

https://codeberg.org/fediverse/fep/src/branch/main/fep/1b12/fep-1b12.md#group-moderation

guild channels should reference their guild in the `context` property (#141) and therefore the `attributedTo` field can be left to be how it's described in 1b12

group dm channels should have no context and have attributedTo be the list of members, since they are all moderators in their own group chat

for normal dms, there's no channel so it doesn't matter

it's defined here: https://github.com/MaddyUnderStars/shoot/blob/94cf6ff9d6b3c6a8958b31f650252f08fba4ad00/src/util/activitypub/transformers/actor.ts#L41-L45

Start in src/util/activitypub/transformers/actor.ts around lines 41-45 and compare the current actor transformation with the linked FEP-1b12 group-moderation rules. Trace the guild and group-DM channel transformations, then verify that guild channels use context and group DMs represent their members through attributedTo as described.
