    pub db: Arc<HirnDB>,
    pub actor_id: AgentId,

Expand description

Engine-side implementation of hirn_exec::extensions::ContextAssemblyRuntime.

Registered once per THINK query execution, capturing the HirnDB reference, actor identity, scored candidates, and context config. ContextAssemblyExec (pipeline mode) calls assemble_from_batches, passing the raw Arrow output from ContextBudgetExec. This makes THINK context assembly a true SendableRecordBatchStream operator rather than an imperative post-step.

§Design Notes

  • The candidates and content_pool are pre-computed before plan execution; they are used as the hydration pool for graph/causal neighbor resolution.
  • Raw Arrow batches from ContextBudgetExec bypass the secondary Lance scan for the top-k candidate set (the Arrow fast path in assemble_think_context).
  • The runtime is RAII-managed via RegisteredContextAssemblyRuntime; the caller must hold the guard until the plan output is decoded.
