Function acknowledge_all 

pub async fn acknowledge_all(
    pool: &PgPool,
    actor: &Actor,
    revision_id: Uuid,
    only: Option<&[Uuid]>,
    note: &str,
) -> AppResult<Acknowledged>

Acknowledges every open impact on a dependent revision with one note – or only those in only (the ones the user saw, so a check flagged a moment ago is not acknowledged unseen). Impacts resolved in the meantime are skipped; if none is left, nothing changes (conflict). Same rules as acknowledge; one transaction, one audit entry per impact.

Invariants

• Permission: CAD editor; the revision is visible (“not found” otherwise) and in a group the actor may edit (403); a note is needed (400); a given list is not empty and names only impacts on this revision (400); at least one impact is still open (409).
• Locks: the open impact rows (FOR UPDATE), before they are resolved.
• Audit: impact.acknowledge per impact.
• Notifications / webhooks: none.
• Atomic: one transaction; impacts resolved in the meantime are skipped and counted.
