 * Durable adapter kind for the canonical session channel and for every

 *
 * The value is locked at `"http"` because it is persisted into durable
 * workflow state under `serializedContext["eve.channel"].kind` and into
 * sandbox telemetry tags as `channel: "http"`. Renaming the value would
 * break rehydration for every in-flight session started under any prior
 * build with "Unknown adapter kind: \"http\"". The `httpChannel` →
 * `eveChannel` rename (commit `bd3d1b43`) intentionally renamed the
 * channel identifier (file name, function name, framework constant) but
 * deliberately left this adapter kind alone — the kind labels the
 * adapter's transport class, not the channel's name, and the same slot
 * is the rehydration target for every behaviorless authored channel
 * regardless of which protocol it speaks.
