Overview

Resolves a single row to its resume + cancel URLs in the current portal.

Both URLs come from the SAME resolved mount, through named route helpers — the cancel target is never derived by string-surgery on the resume URL, which would drop query params and break for a run whose current_step is still nil (there the resume URL is the bare launch path, so lopping off its last segment yields a non-route).

Instance Method Details

#resolve ⇒ Hash

Returns cancel_url:, reason: — reason is non-nil exactly when no resume URL could be built. The two URLs resolve INDEPENDENTLY: a run with no current_step has no stepped resume URL, but is still perfectly cancellable, and leaving the user no way to clear it would strand the row in their chooser forever.
