- Modal bulk upload: stream base64 payload through proc.stdin in 1MB chunks instead of embedding in command string (Modal SDK enforces 64KB ARG_MAX_BYTES — typical payloads are ~4.3MB) - Modal single-file upload: same stdin fix, add exit code checking - Remove what-narrating comments in ssh.py and modal.py (keep WHY comments: symlink staging rationale, SIGPIPE, deadlock avoidance) - Remove unnecessary `sandbox = self._sandbox` alias in modal bulk - Daytona: use shared helpers (unique_parent_dirs, quoted_mkdir_command) instead of inlined duplicates
