+`o` is pre-declared `{}`; assign results directly to `o.key` (no `const x=` then repack). Thenable `o.*` values are auto-awaited **at return only** — `o.x=sh(c)` needs no await, but a shorthand result used inline (concat, template, arg to another call) does: `const c=await cat(f); put(f,c+s)`, never `put(f,cat(f)+s)`. **End the script with bare `o`** (or a statement) to return the full object; ending on `o.x=...` returns just that one value.

+Note: ${FILE_OBJECT.filename} was modified, either by the user or by a linter. This change was intentional, so make sure to take it into account as you proceed (ie. don't revert it unless the user asks you to). Don't tell the user this, since they are already aware. The diff was omitted because other modified files in this turn already exceeded the snippet budget; use the Read tool if you need the current content.
