Entry records the alerts that were firing and resolved at the time of the last notification, but not the ones that were muted. The mute stages drop muted alerts before the dedup stage runs, so they are absent from both lists and indistinguishable from alerts that stopped firing. Add a muted_alerts field alongside them, an IsMutedSubset helper mirroring IsFiringSubset and IsResolvedSubset, and a mutedAlerts parameter on Log(). The field number 9 is new; existing field numbers are untouched, so entries gossiped by peers that predate this field decode with MutedAlerts unset, and entries this version writes are readable by those peers. Nothing populates the field yet: SetNotifiesStage passes nil, and the dedup stage does not read it. This is the schema and write path only, so that the behavior change can be reviewed on its own.

The mute stages remove muted alerts before the dedup stage runs. MuteStage records the hashes it drops in the context, but the time interval stages do not, and once every alert in a group is muted MultiStage stops, so no later stage runs at all. A fully muted group is therefore indistinguishable from a group with nothing in it. - Extract MuteStage's recording block into recordMuted, and use it in TimeMuteStage and TimeActiveStage, so that all three mute stages record what they drop. Like MuteStage, they do so unconditionally: the context is populated either way. - Add MutedMultiStage, a MultiStage that keeps going when a mute stage has emptied the group. PipelineBuilder picks it, and SetNotifiesStage records the muted hashes only when --enable-feature=muted-alerts-in-nflog is set; with the flag off the pipeline and the notification log entries are unchanged. - Guard RetryStage against an empty alert set so a muted group is not delivered as an empty notification, and is not counted as one either. The hashes written to the log are sorted, so entries stay stable across flushes and across peers. Nothing reads muted_alerts yet. With the flag on, a fully muted group now records an entry with an empty firing set. Co-Authored-By: Claude Code Signed-off-by: Geoff Wilson <geoff@gr-oss.io>
