Narrow harness-loading seam for turn execution (EVE-872, EVE-881).

Implementations project their stored harness records into the portable HarnessDefinition — the effective execution environment configuration. Parent-chain inheritance is resolved behind this seam (root-to-leaf, via the same overlay merge semantics the runtime uses), so callers receive one effective layer. Stored Harness persistence records live in everruns-platform and never cross this boundary.

Contract: records that exist but cannot execute (archived or deleted) must yield an error from HarnessStore::get_harness, so lifecycle validation is enforced at the loading seam before host execution begins.

Required Methods

fn get_harness<'life0, 'async_trait>( &'life0 self, harness_id: HarnessId, ) -> Pin<Box<dyn Future<Output = Result<Option<HarnessDefinition>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Get the effective (inheritance-resolved) execution definition for a harness by id. Returns Ok(None) if the harness does not exist.

Provided Methods

fn get_harness_blocker<'life0, 'async_trait>( &'life0 self, harness_id: HarnessId, ) -> Pin<Box<dyn Future<Output = Result<Option<DependencyBlocker>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Execution-availability probe for dependency-blocker detection.

Returns None when the harness exists and can execute. Hosted stores override this to report DependencyBlocker::HarnessArchived / DependencyBlocker::HarnessDeleted from the stored lifecycle status; the default treats a missing record as deleted.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
