Following each candidate non-wearer release, the generator opens an EOT
opportunity and scans forward until a floor-level wearer entry or a competing
non-wearer onset terminates it. A retained \textsc{Wearer-Onset} candidate
therefore contains two immutable anchors: the non-wearer release
(\emph{opportunity anchor}) and the subsequent floor-level wearer onset
(\emph{behavior anchor}). The response delay is stored explicitly. Silence
duration alone does not cancel the opportunity; an unpaired wearer onset is
kept only as an audit control and does not enter the primary EOT queue.
EOT candidate construction starts from each observed floor-level wearer onset,
which is retained as the immutable \emph{behavior anchor}. The generator then
searches backward for preceding non-wearer releases. A release remains an
admissible \emph{opportunity-anchor} option only when the wearer stays silent
and no new non-wearer onset or already-active other floor invalidates the
intervening interval. Silence duration alone does not reject an option. Thus
each wearer onset contributes at most one primary review item rather than one
item per preceding release. The semantic annotator must either select one of
the supplied release options as the trigger or reject the EOT interpretation;
it cannot introduce a new timestamp. The selected opportunity and observed
behavior anchors deterministically define the valid prediction interval. A
wearer onset without an admissible release is retained only as an audit control.
