`session.history` reads an attached Session in memory or inspects a cold log through persistence without resuming or publishing an Agent, then pages on append-origin message boundaries. `maxMessages` counts `user/message` and `assistant/message` events that entered the surface by appending, so a model-only replacement copy consumes no quota. Each page stays one contiguous raw event range, which keeps a compaction's log-only `compact/summary` record on the same page as the replacement that cites it.
An optional `SessionEventView` is a non-persistent presentation sidecar. Tool calls/results keep their existing Host presenters. A Schedule dispatch remains raw on append; after an acknowledged `session/flushed(session, throughSeq)`, the gateway advances an exact-Session `WeakMap` cursor with `max`, derives newly covered receipts through the Schedule package, and redelivers the identical event with `{ for: 'event', presentationKey: 'schedule/reminder', view }`. Reversed flush completion cannot move the cursor backward or duplicate a receipt. Attached history adds these views only within a persistence-inspected prefix whose header and every event match the live identity; unavailable, failed, or mismatched inspection serves raw history without the sidecar. Detached history is already a persisted prefix.

The durable event type selects the client renderer. Reversed flush completion cannot move the cursor backward or duplicate a receipt. Attached history adds these views only within a persistence-inspected prefix whose header and every event match the live identity; unavailable, failed, or mismatched inspection serves raw history without the sidecar. Detached history is already a persisted prefix.
`session.history`'s tail page (`beforeSeq` absent) additionally carries an optional `projections` block — the watermark snapshot of every unit registered on `ctx.sessionProjections` (`@deepseek-ai/dsh-session-projection`), with `asOfSeq` = the last event seq the values reflect (`-1` on an empty log). The gateway also subscribes to the registry's change feed and mints a `session/projection` mux frame per changed unit (`{sessionId, key, value, seq}` — live push state, never logged; clients hold one generic per-session value store under higher-seq-wins). The carrier holds zero domain knowledge (each value passed its unit's own schema inside the registry; the wire schemas keep `values`/`value` wide); loadOlder pages never carry the block, and a composition without the registry serves histories without either surface.
