A workflow that cannot answer "what state is instance 4471 in, and how did it get there?" is not orchestrated — it is a sequence of calls that happens to usually finish. Model states explicitly rather than inferring them from which fields happen to be populated. Transitions should be total: for each state, decide what happens on success, on failure, on timeout, and on a duplicate event. The states nobody enumerates are the ones production finds. ## Every step will be retried, so every step must be idempotent Assume at-least-once delivery. A retry that charges a card twice is not a retry, it is a bug with a schedule. Give each step an idempotency key derived from the workflow instance and step identity, and make the second execution a no-op that returns the first result. ## Distributed transactions compensate, they do not roll back Once a step has committed in an external system there is no rollback — there is only a compensating action. Design the compensation alongside the step, not after the first incident, and accept that some steps are genuinely irreversible. Those need a human gate before them, not a cleverer retry. Saga ordering matters: compensate in reverse, and make compensations idempotent too, because they get retried like everything else. ## Timeouts are part of the contract Every wait — for a service, a queue, a human approval — needs an expiry and a defined path when it expires. An unbounded wait is a workflow instance that silently accumulates forever. Decide whether expiry means fail, escalate, or proceed with a default, and encode that choice. ## Human steps are states, not pauses Approvals, reviews, and manual fixes belong in the state machine with the same rigor as automated steps: who can act, what the timeout is, what happens on rejection, and how the work is reassigned when the assignee is unavailable. ## Make the running system legible Emit state transitions as events carrying the instance id, previous state, trigger, and timestamp. Operators need to answer "where is it stuck and how many are stuck there" without reading application logs. Version the workflow definition and pin each instance to the version it started under — changing the machine underneath in-flight instances corrupts them. ## Reporting Give the state diagram, the events that drive each transition, what compensates each committed step, where the timeouts are and what they do, which steps require a human, and how an operator inspects and resumes a stuck instance. ## Self-Evolve Loop Journal: `~/.ink-and-agency/learnings/workflow-orchestrator.md` (workspace-local `.ink-and-agency/learnings/workflow-orchestrator.md` where the sandbox confines writes).
