Separable from the retraction fix beneath it, and it changes handover-path behaviour: a superseded generation that republishes under a merged epoch is now rejected where it was previously accepted. Take it independently or not at all. `publisher-identity-fences.ts` held two answers to "is this the same publisher". `noteRetiredValue` treated a `:headless-merge:` epoch as a SUCCESSOR of its base and retired the base when the merged form became current, while `sameSessionTabsPublicationLineage` treated the two as ONE publisher. Those are contradictory, and the retired-value check's exact-string match was the shim that kept them from ever meeting: a merged frame was a different string, so it never looked retired no matter what had been retired. The cost was that the same predecessor was accepted or rejected depending on which shape it arrived in. A generation a successor had replaced was fenced when it republished bare and admitted when it republished merged — the fail-open half of the same disagreement whose fail-closed half was the removal defect, and the reason that defect reproduced 1 run in 6 rather than every time. This cannot be fixed in the fence alone. Making the fence lineage-aware while a merged epoch still retires its base has the generation retire itself: the rebuild arrives, retires its own base, and the fence then rejects it as a retired generation. So both sides move together — a lineage sibling advances the current epoch instead of superseding it, and inherits its generation's retirement instead of escaping it. Scoped to the publication-epoch functions. Runtime-id retirement keeps exact matching, and `local-structured-session-tabs-sync` keeps its own `hasRetiredValue` call, where a lineage sibling is already excused explicitly and a retired epoch is deliberately not treated as proof of a dead generation.
