Observer Fragment

undefined:

A observer fragment is a function fragment that acts as an observer or silent watcher and funnels information or memory about experiences in the front or body into a reservoir, usually without adding their own thoughts and interpretations.

Reservoir Interaction

 * Logging: memories that are not personal to a specific headmate get put into a reservoir; this may include things that happen while the body is on autopilot and may be in "third person perspective". Logged memories may feel similar to a "security camera recording" of events in shared reality and may be very rudimentary or lack emotions, opinions, or thoughts connected to occuring events. Situations involving different fronters may feel similar and impersonal when accessed. This may feel like emotional amnesia.
 * Transcribing: a fronter's experience and perspective gets abstracted and put into a reservoir; these memories may feel more personal or have more emotional context than logged ones.
 * Striking: memories that are already in the reservoir get retroactively removed by a gatekeeper such as an eraser or a member with similar abilities. This may get increasingly difficult the longer memories have been logged, and may or may not be fully possible for transcribed memories.

In systems with headspace amnesia, fronters may only be able to access logged and transcribed memories. Members with access to both their own and reservoir memories may find differences between personal and logged memories.

A front block may keep spoilers from reaching the front to avoid being logged or transcribed.

Some gatekeepers (or members with similar abilities) may be able to disable an observer fragment for a short time while certain headmates front, or they may be able to strike memories of spoilers after the fact. This may lead to blackouts for systems that otherwise have shared atrial memory.

Rivulus or atrium systems, as well as any other system with front memory, may have observer fragments that manage that reservoir.

An observer fragment may also be considered an archival fragment and may be frontstuck or part of the front.
