Enum WaitReason

        outstanding: usize,
    },

Why a run’s status is RunStatus::WaitingInput.

WaitingInput alone is several unrelated situations wearing one word, and they call for opposite responses: a fan-out parent whose workers are churning is healthy and needs nothing, while a run parked on a tool-approval prompt is stopped dead until a person answers it. Issue #184 is what happens when the two are indistinguishable - an operator reading waiting across a factory concluded it had stalled and started killing healthy runs. Issue #431 is the same conflation reaching every client that reads meta.json.

Derived on demand from markers the engine already sets, by wait_reason_from; nothing tracks it separately, so it cannot fall out of sync with the status it explains. It lives here rather than in the runtime because it is both reported live over the control socket and written to meta.json, and one vocabulary across those two is the whole point.

Deliberately not new RunStatus variants: the status is matched exhaustively across the codebase and serialized two ways on the wire, so splitting it would break every consumer to express something that is not a new state. The run really is waiting; this says on what.

Variants

ToolApproval

Blocked on a tool-approval prompt. Needs a person (or --yolo).

UserPrompt

Blocked on a question the agent itself asked (ask_user_*, present_for_review). Needs a person.

TaintGate

Blocked on a taint-gate clearance prompt. Needs a person.

InteractionPoint

Blocked on a blueprint stage-boundary checkpoint. Needs a person.

FanOutWorkers

Parked while fan-out workers run. Healthy; resolves on its own.

Fields

outstanding: usize

Workers still to finish, counting both running and not-yet-started.

Children

Parked while spawned sub-agents run (requires_children). Healthy; resolves on its own.

Fields

outstanding: usize

Children that have not reached a terminal status.

NeedsSetup

Parked because something on the machine has to change before this run can go on: a provider it needs is not configured, a key was rejected, an account is out of credits.

These used to end the run. They are all deterministic and all outside the run’s control, so ending it threw away everything it had done to punish a person for a typo in config.toml. The run holds its place instead, and lev resume picks it up once the machine is fixed.

The distinction that matters is not “is there a fix” but “does the fix let this run continue”: a broken blueprint is equally deterministic and equally fixable, and still cannot be resumed into, because the blueprint was read at spawn.

Fields

blocker: SetupBlocker

Which kind of problem, so a client can offer the right thing to do rather than parse the sentence below.

remedy: String

What to do about it, in a sentence, for whoever reads the run.

Implementations
