 - SDK executes Server's assembled `HttpRouter` in memory. It opens no listener and performs no network I/O, while preserving Server routing, middleware, codecs, handlers, and errors.
 - The Effect Client and SDK re-export their decoded datatype facade from Schema so callers do not depend on internal package locations or Core's versioned names.
 - A capability intended for both networked and **Embedded OpenCode** belongs in the authoritative public `HttpApi`; embedded-only same-process capabilities extend **Embedded OpenCode** separately.
-- `sessions.events({ sessionID, after })` is one public Session-scoped event stream. It verifies the Session, captures a fixed durable cutoff after registering observation, replays durable events in `(after, cutoff]`, emits one authoritative process-local `session.activity` value, then continues with committed durable events and live-only Session output fragments. Only durable events carry aggregate-sequence cursor metadata.
+- `sessions.events({ sessionID, after })` is a public durable Session event stream. It verifies the Session, replays durable events after the optional aggregate sequence, continues with newly committed durable events, excludes live-only fragments, and is transported as SSE in both networked and embedded modes.
 - `events.subscribe()` is a distinct public instance-wide live stream for Session and non-Session activity. It has no replay guarantee and includes connection, heartbeat, and instance-disposal lifecycle events; consumers recover from disconnection by refreshing authoritative state.
 - A Session ID is not an optional filter on `events.subscribe()`: instance-wide live events and durable Session events have different schemas, replay guarantees, cursors, lifecycle events, and failure behavior.
 - The initial common OpenCode Client does not expose server-global event aggregation. `events.subscribe()` is bounded to the connected OpenCode instance or workspace; any future cross-instance administrative stream requires a separately designed API.
 - `events.subscribe()` does not automatically reconnect after transport loss. The live-only stream fails with `ClientError`; consumers refresh authoritative state before explicitly opening a new subscription because events missed during disconnection cannot be replayed.
-- `sessions.events({ sessionID, after })` returns the generated HTTP client's cold Session event stream and does not build reconnection policy into the endpoint or client constructor. Transport loss fails the stream with `ClientError`. Callers resume with the last observed durable sequence; live-only fragments are not replayed, and every connection receives a fresh authoritative activity value.
-- The Session event stream treats database rows as authoritative and process notifications as bounded, non-blocking wakeups. Before emitting an observed live-only fragment it drains later durable rows, preserving causal durable start boundaries without exposing an additional fence field.
-- Aggregate deletion currently removes the Session's durable event rows and sequence, including deletion history. The Session event stream therefore cannot promise replay after deletion until retention or a typed history-expired outcome is designed.
+- `sessions.events({ sessionID, after })` returns the generated HTTP client's cold durable event stream and does not build reconnection policy into the endpoint or client constructor. Transport loss fails the stream with `ClientError`. Callers may compose an explicit resuming stream above it by retaining the last observed durable sequence and opening a new subscription with `after`; any reusable resume helper remains a separate API design question.
 - The stable `sessions.list(...)` design returns a **Page** in both networked and **Embedded OpenCode**; embedded execution does not define a separate unbounded array-returning list operation. The beta client currently preserves the existing HTTP `{ data, cursor }` envelope until emitter-level Page projection is implemented.
 - Session list cursors are opaque branded values carrying continuation query and ordering state. Consumers pass them back unchanged and do not inspect storage anchors or encoded filter fields.
 - A Session list continuation accepts only its opaque cursor. Scope, filters, ordering, and page size are fixed by the initial query and carried by that cursor.

 Eager local-tool execution is intentionally unbounded in the current local slice. This minimizes tool latency but does not increase SQLite settlement throughput: Session-event publication remains serialized per provider turn. Before broadening exposure, revisit per-turn call limits, output truncation, and operational backpressure using observed workloads. The `session.next.*` event schemas remain experimental and unshipped; databases created by earlier experimental builds are disposable rather than compatibility targets.
 
-The synchronized `session.next.*` event family and projected Session-message model predate this branch. Projected Session messages retain their source aggregate sequence so canonical context ordering and `sessions.messages(...)` pagination follow durable event order even when caller-supplied IDs or timestamps do not. Consumers use `sessions.events({ sessionID, after? })` for one Session-scoped stream containing replayable lifecycle/output events, process-local activity, and connected live-only output fragments.
+The synchronized `session.next.*` event family and projected Session-message model predate this branch. This slice refines their replay contract: projected Session messages retain their source aggregate sequence so canonical context ordering and `sessions.messages(...)` pagination follow durable event order even when caller-supplied IDs or timestamps do not. Consumers can use `sessions.events({ sessionID, after? })` to replay durable `session.next.*` events after an aggregate sequence cursor, then tail durable events without a race. Live-only text, reasoning, and tool-input fragments remain available through EventV2 subscriptions for connected renderers; they are intentionally absent from the replayable Session stream.
 
-The stream registers observation, captures one fixed durable cutoff `B`, emits durable rows in `(after, B]` in aggregate-sequence order, and then emits exactly one authoritative `session.activity` value. Only events carrying `durable` metadata advance the cursor. Activity and text, reasoning, compaction, or tool-input deltas are process-local and never replay after reconnect. Activity means foreground execution ownership in this process; `false` does not describe a terminal outcome, and background work does not activate its parent Session.
+The first `sessions.events(...)` contract is durable-only during both replay and live tailing. This keeps one cursor equal to one persisted aggregate sequence and is sufficient for reconnect-safe consumers. A later UI-facing API may optionally interleave live-only deltas while connected, but those fragments must remain explicitly ephemeral: they cannot advance the durable cursor, replay after reconnect, or be mistaken for publication boundaries.
 
-Durable event tail notifications are advisory. Each active tail uses bounded non-blocking observation and re-queries SQLite after a wake. Repeated commits may coalesce because durable rows, not in-memory notifications, preserve every event and sequence. A live-only fragment is emitted only after draining later durable rows, which fences dependent deltas behind their committed start events. If a live consumer cannot keep up, the stream closes rather than blocking Session execution or SQLite writers. Aggregate deletion still removes durable history and remains a documented replay limitation rather than being redesigned here.
+Durable event tail wakeups are advisory and edge-triggered. Each active tail owns one sliding-capacity-1 dirty signal for its aggregate and re-queries SQLite after a wake. Repeated commits coalesce while the tail is busy because durable rows, not in-memory notifications, preserve every event and sequence. Subscribe and register the dirty signal before historical replay, then remove it when the tail closes, so replay handoff cannot miss a commit and inactive aggregates retain no wake state.
 
 Event replay owner claims are separate from clustered Session execution ownership. The former already fences synchronized projection reconstruction; the latter still needs distributed active-run acquisition, stale-runtime rejection, interruption, and placement orchestration.
