## Update Evaluation Group

**put** `/v5/evaluation-groups/{group_id}`

Replace an evaluation group's attributes and, optionally, its membership.

This is a full replacement of the group's attributes: every attribute field (name,
description, tags, metadata) is written from the request, so omitting an optional
field clears it rather than leaving it unchanged. Use PATCH instead to update only
selected fields and to merge (rather than overwrite) metadata. Membership is replaced
only when evaluation_ids is supplied: the resulting members become exactly that set
(added/removed by diff against the current members), it must contain at least one ID
with no duplicates, and every ID is validated for existence and account access or the
request fails with a 400. When membership actually changes, a best-effort Temporal
workflow is started to recompute the group's dashboard widgets; this is fire-and-forget
and its failure does not fail the request. Removing members hard-deletes the
corresponding chart columns and any charts left with no columns.
