Durable workflow execution and fail-closed guards for multi-party systems.

Development + product architecture[TypeScript][Rust][Action Graphs][Durable Workflows]

01 / The premise

Can identity and action remain composable without collapsing into one centralized hierarchy?

An Apache-2.0 action-graph engine for long-lived multi-party workflows: explicit idempotency keys, suspendable waits, reconciliation sweeps before retry, and fail-closed consent and version guards.

02 / What took shape

  • Suspendable waits & compensating sagas
  • Explicit idempotency & reconciliation loops
  • Fail-closed consent and version guards

03 / Looking back

The useful residue.

The project reframed orchestration as nested autonomy. Its most useful insight was architectural: boundaries do not only separate components; they determine which kinds of agency remain possible.
