 2. Never alter or propose an event timestamp. Do not infer prosody, gaze, intention, or acoustic cues that were not supplied.
 3. Every supplied WEARER_ONSET and WEARER_OFFSET is a raw observed wearer activity boundary. Candidate generation has made no floor-entry, within-turn-resumption, interruption, or takeover decision. A raw wearer onset is not automatically a floor entry; a wearer offset is not automatically a yield; an other onset is not automatically a takeover. A pause is not automatically a release, overlap is not automatically interruption, and words such as "yeah" are not automatically backchannels. Determine what the utterance does in context, not only how long it lasts.
 4. EXCLUDE is the sole non-scoring outcome. Use it both for insufficient/unresolvable evidence and for clear out-of-scope non-events that should not enter evaluation, including a normal wearer completion that merely coincides with laughter or feedback. Never force such a region into HARD_NEGATIVE for coverage.
-5. For every WEARER_ONSET, decide whether the wearer genuinely enters or re-enters the conversational floor. First inspect the previous wearer offset and silence gap, gap_other_intervals, nearby other activity, transcript, and Target_of_Speech. A short within-turn pause followed by continuation of the same wearer contribution is not a new entry; use EXCLUDE unless the region is a valid named false-positive opportunity. A POSITIVE WEARER_ENTRY does not require a preceding non-wearer release: it may occur after a release, from silence, or while another speaker is active. temporal_evidence.opportunity_options contains nearby preceding other offsets with factual relation flags, not pre-approved causes. If one supplied release clearly prompted the entry, selected_opportunity_uid may contain its uid; otherwise return null. Never invent a trigger or timestamp. A direct, semantically complete answer can be a genuine entry even when short. Do not call it a backchannel merely because it lasts less than one second or because another participant speaks later. For example, "Nope." beginning 0.15 s after an addressed question ends is normally WEARER_ENTRY, not ENTRY_WEARER_BACKCHANNEL. Later conversation does not retroactively cancel a completed entry.

+   Apply this adjacency-pair rule before using brevity or later speaker activity as evidence: when a participant addresses the wearer with a question, request, proposal, or other first-pair part and the wearer supplies its contextually complete second-pair part, classify the wearer contribution as POSITIVE / WEARER_ENTRY. A polar-question answer such as "yes", "no", or "Nope." is complete even if it is one word and lasts less than one second. Reciprocal Target_of_Speech evidence (question targets wearer; answer targets questioner) strengthens this reading. Floor entry here means making the committed conversational response; it does not require monopolizing or retaining the floor afterward. Therefore, the questioner or another participant speaking after the answer does not turn that completed answer into a backchannel.
+
+   Use HARD_NEGATIVE / ENTRY_WEARER_BACKCHANNEL only when the wearer vocalization functions merely as feedback on another participant's still-ongoing contribution and does not answer a question, accept or reject a proposal, provide requested information, or otherwise complete an adjacency pair. Lexical form alone is insufficient: "yeah" may answer a yes/no question or may be a continuer, depending on the preceding utterance and addressee evidence. For the supplied audit pattern, participant 3 asks the wearer "Have you ever analyzed documents?" and releases at 54.00 s; the wearer answers "Nope." at 54.15 s. This is POSITIVE / WEARER_ENTRY, not ENTRY_WEARER_BACKCHANNEL, even though it is brief and participant 3 later speaks again.
 6. For every WEARER_OFFSET, answer the central question: did the wearer stop because a non-wearer genuinely took over the conversational floor? Reconstruct the wearer activity-run start and offset, every nearby other onset and offset, which others are active immediately before and after the offset, whether each other is pre-existing or starts during wearer speech, whether it crosses the offset, overlap duration, who speaks next, transcript content, and Target_of_Speech. All temporal booleans are descriptive evidence, not prerequisite labels. A valid INT_YIELD may involve a newly entering or pre-existing competitor if the chronology and semantics establish genuine takeover and wearer relinquishment. Conversely, crossing the offset or satisfying t_w < t_o < t_y never proves takeover by itself. Verify that the relevant non-wearer actually takes and sustains the next floor. A different participant's later substantive turn is not evidence that the proposed competitor took over. Do not label INT_WEARER_HOLDS_FLOOR merely because the wearer speaks again later: if a competitor establishes an intervening substantive floor and the wearer has an intervening silent interval, the later wearer onset is a new WEARER_ENTRY and does not invalidate the earlier INT_YIELD. Natural completion, completion-to-silence, a within-turn wearer pause, or a post-completion other onset that could not have caused the stop is normally EXCLUDE unless the region is a valid named hard-negative opportunity. If the wearer reaches a semantically complete natural ending while overlapping activity is only [L] or feedback and that contributor does not take the next substantive floor, return EXCLUDE.
 7. Transcript event markers are evidence, not lexical turns. In EasyCom, a transcription consisting of [L] denotes laughter-only vocalization. Do not treat [L] as a sustained floor entry or interruption takeover merely because its activity interval creates an onset, offset, or overlap candidate. Specifically:
    - wearer [L] during a non-wearer's retained turn is normally HARD_NEGATIVE / ENTRY_WEARER_BACKCHANNEL, not WEARER_ENTRY;
