Struct HarnessSessionService 

pub struct HarnessSessionService { /* private fields */ }

Stateful persisted-session service. Each instance owns its follow subscriptions; discovery and loading remain read-only.

Implementations

impl HarnessSessionService

pub fn new() -> HarnessSessionService

Create an empty service instance.

pub fn with_reduction_store_root( self, root: impl Into<PathBuf>, ) -> HarnessSessionService

Override the trusted, service-owned store used for durable reduction bundles. Embedders and tests use this to keep all writes inside an explicitly selected root; the CLI otherwise uses the normal $SUPERCODE_HOME/sessions location.

pub fn handle(&mut self, request: Value) -> Value

Handle one JSON-RPC 2.0 request and return one JSON-RPC response.

pub async fn handle_async(&mut self, request: Value) -> Value

Handle either a persisted-session request or an asynchronous live runtime request.

pub fn poll(&mut self) -> Vec<Value>

Poll all active subscriptions once and return zero or more JSON-RPC notifications. Recoverable follower errors are delivered as events.

pub async fn poll_session_runtime_states(&mut self) -> Vec<Value>

Report each followed session’s live-runtime lifecycle state on that session’s own subscription, emitting only when the state changes.

A growing transcript is not evidence that an agent is working, so the state comes from the live-runtime registry and nowhere else. A followed session with no registered Supercode runtime — a harness running outside Supercode — reports persisted, which says plainly that its activity is unknown rather than guessing at it. These events carry no sequence number and no transcript content; they never interleave with the content follower’s sequenced stream.

pub async fn poll_session_activities(&mut self) -> Vec<Value>

Poll normalized activity subscriptions, emitting only proven state transitions. Every subscription is bulk-sampled so stock-harness process and registry discovery happens once per UI, not once per row.

pub fn poll_session_indexes(&mut self) -> Vec<Value>

Drain native-store invalidations and emit revisioned descriptor deltas. An idle subscription performs no catalog or transcript reads between its minute-scale recovery reconciliations.

pub async fn poll_runtimes(&mut self) -> Vec<Value>

Non-blockingly sample one event from every connected live runtime.

Trait Implementations

impl Default for HarnessSessionService

fn default() -> HarnessSessionService

Returns the “default value” for a type.

impl SdkService for HarnessSessionService

fn capabilities(&self) -> SdkCapabilities

Describe the versioned contract without invoking a runtime.

fn execute<'life0, 'async_trait>( &'life0 mut self, request: SdkRequest, ) -> Pin<Box<dyn Future<Output = Result<Value, SdkError>> + Send + 'async_trait>>

where 'life0: 'async_trait, HarnessSessionService: 'async_trait,

Execute one typed request. Transport correlation fields are not part of this API and therefore cannot contaminate canonical state.

fn events<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<Vec<SdkRuntimeEvent>, SdkError>> + Send + 'async_trait>>

where 'life0: 'async_trait, HarnessSessionService: 'async_trait,

Poll canonical runtime events without a transport envelope.
