The Gateway serves the goal domain as Remote endpoints, and a Remote method
picks its receiver Service from a generated descriptor — `clear(agent, ref)`
takes its agent as a PARAMETER, so the invocation is direct and the receiver
resolves on the host. Behind the preset's entry-local realm there was nothing
to resolve, and every browser goal call answered `service-unavailable`: the
composer's Clear goal button left the bar on screen.
That is the `bash-env` criterion read from the other side. Injection is not the
only host relationship a Service can have; being READ from a host row is one
too. The registry is keyed by session, so one host instance serves every
session exactly as it did before presets. The preset keeps the model-facing
tool, which is the choice a preset is for.
Also reverts the cold-transcript presenter resolve: resuming an agent to reach
its presenters made the context meter drop its cache and token counts on every
cold-opened session, trading one silent degradation for another. The card
degradation it addressed is diagnosed and still open.
A preset registers its tools into the agent's OWN layer, so `session.history`
served while no agent exists found no presenter at all and every card degraded
to the generic renderer — silently, because a viewless entry is also what a
tool with no presenter produces. The web client opens a session by reading its
transcript, so this was the ordinary path, not an edge: the write row lost its
diff card, and with it the `locations` the produced-files row derives from.
The read now resolves the agent through the same deduplicated resume every
other session method takes, but only when a roster is composed: a deployment
without presets keeps its tools on the host layer, which needs no agent to
address, and keeps the storage-only read unchanged. A resolution failure stays
a successful read.
The composer's preset seat stays removed here — this layer moved it to the
hero chip and the session-header action — so only the model seat takes the
`modelSeatLocked` narrowing master introduced.

The Client API carrier's `agentPresets` member was the one member of its class
without an `IApiClient[...]` annotation. Inferring it inlined `AgentPresetEntry`
into the emitted declaration by the specifier TS picks — the host `index.ts` —
dragging the whole gateway, and with it the host `Context` merges, into every
Client program importing the carrier. Annotated like its siblings.
`ApiRemoteAgentOptions.setup` now takes the inspected session rather than its
header alone: this layer resolves a resumed session's preset from the LOG,
because a session that switched while blank ran its turns under the newer
composition and the header is written once at creation.
