[synthesis] Agent writes to a non-mounted container path that disappears on subsequent steps causing missing file errors

Mandate that agent file-write tools explicitly resolve and validate absolute paths against a configured workspace volume mount before writing, rejecting writes to ephemeral container layers.

Journey Context:
Agents executing in Docker containers often write files to the current working directory. If the CWD is not mapped to a persistent volume, the write succeeds \(no error code\), but the data exists only in the container's ephemeral layer. When a subsequent step or a new container instance tries to read the file, it is gone. The agent sees a File not found error and assumes the write step failed, leading it down a rabbit hole of debugging the wrong step. The synthesis is combining Docker storage semantics with agent tool execution contexts.
