Module declared 

A DECLARED command executed as an activity.

DeclaredCommandAction is the sibling of super::ShellAction, and the difference is where the splitting happened. A ShellAction is handed a command LINE and parses it into an argv here. A DeclaredCommandAction is handed argvs that the AWL emitter already produced from a command declaration — one argv per body line, the document’s exported environment and working directory beside them — so nothing on this side ever holds a string that could be re-split.

The body ruling, honoured where the processes are

A command body’s lines run SEQUENTIALLY, in order; the first non-zero exit fails the command; and the command’s captured output is the CONCATENATED stdout of every line in order. This is the one executor the server’s declared-body dispatcher and the aion worker awl executor share, so the ruling cannot be answered differently by venue.

Everything else is deliberately the same machinery as the string-body executor: execve with no shell interposed, and the world of super::world::place_in_declared_world — closed stdin, the host environment cleared but for PATH, the document’s exports applied in declared order over it — plus process-group containment and line-by-line transcript streaming. Two executors that agreed about the argv and disagreed about the world the process runs in would be two different bodies wearing one declaration.
