Mastra is a framework for building AI-powered applications and agents with a modern TypeScript stack.

/**
 * Builds the per-task evented workflow that owns executor + retries.
 *
 * Shape: outer workflow runs an inner `[run-attempt, classify-outcome]`
 * workflow inside a `dountil` loop. `run-attempt` invokes the executor and
 * categorises the outcome; `classify-outcome` persists final state, advances
 * retry bookkeeping, and decides whether the loop is done. The dountil
 * predicate exits on `done === true`.
 *
 * The nested-workflow-as-loop-body path lives in
 * `processWorkflowEnd → processWorkflowLoop` and was fixed in PR #16312.
 * Suspend/resume routes through the runtime's nested-workflow auto-detect
 * (`processWorkflowStepRun` resume branch).
 *
 * Step bodies close over `manager` directly — the bg-tasks layer is the only
 * consumer of the `@internal` private fields.
