Because the projection is log-ordered, the node array is seq-monotonic by construction: log-only `command/run` / `command/done` nodes splice in by seq, `Session` merges interrupted frozen nodes by their fractional seqs, and a window whose checkpoint cites a shadowed range outside it renders the marker with nothing logged. The marker's summary text, replaced-item count, and estimated shadowed-token count come from the checkpoint's cited `compact/summary` event; a window cut that left that event outside makes those fields unavailable, and a later page that supplies it resolves them. `CommandNode.outcome.sourceEventSeq` preserves a successful command's explicit reference to that summary event, allowing the presentation layer to pair `/compact` with its checkpoint without parsing settlement copy or assuming the two rows are adjacent. Performance contract: one append materializes at most one node and copies the projection only when it adds that node; an event that changes no node keeps the previous array reference (a chunk storm costs nothing), and unchanged nodes keep their object identity.
A Host may redeliver the same Session event seq with a new or changed non-persistent view after the event reaches its presentation commit point. `Session` first requires deep event identity, then upgrades only the sidecar; a generic event view becomes one `PresentedEventNode` keyed by the durable event type. Tail loading and true gap repair continue to use the existing `liveBuffer`. Ordinary `loadOlder` leaves live-tail appends in the current window and prepends its page after the await, while an overlapping late sidecar upgrades immediately. Reconnect advances the generation and clears page or repair ownership, so an older request's result or `finally` cannot mutate or block the rebuilt window.

Tail loading and true gap repair continue to use the existing `liveBuffer`; repair continues while each accepted snapshot advances the tail and a buffered gap remains, while an identity-conflicting snapshot triggers a full resync.
