A subagent row that run 1 created and run 2 resumed kept run 1's creation fence, so settling run 1's death marked run 2's live subagent unverifiable. Claude background tasks reuse their rows the same way (a matching parent tool use, or a parentless row). Rows of reusable child execution now also name their execution owner: the fence of the child process whose report the write copies, captured when that report arrives, never the lease that is current when a queued write flushes. - Subagent rows: the host captures the live child's fence when its child-work report changes the records, and rewrites a running subagent another child now reports even when its text is unchanged. - Claude background-task rows: written through that child's own event sink, which stamps its bound fence. - Creation provenance (`ownerFence`) is unchanged. Writes that do not state an owner (settlement, Pi's start usage, ACP session/load replay, ACP tasks) keep it, and a row without one falls back to its creation fence. `journal.itemFence()` now answers whose execution an item is (`executionOwner ?? ownerFence`), so every settlement and liveness read, inside its write transaction, follows the run that resumed the work. Also drops the event sink's compatibility alias for the identity resolver (the Codex sink names the resolver itself), keeping the sink under its line limit.
