Detailed Description

class chronon::observe::TimelineCounter;

Push-model counter track: explicit samples on the Perfetto timeline.

Independent of the pull-model Counter/counters.csv machinery — sample() is an event through the trace channel, so temporal filters apply and lookahead rollback discards speculative samples.

TimelineCounter occ_{this, "lsq_occupancy", "entries"};
occ_.sample(lsq_.size());
