The stored bits themselves were read-only.\n\n### 2. Actions Taken\n- Verified the file exists via `ls -la` and `stat`.\n- Inspected the numeric mode (`%a`), symbolic mode (`%A`), and write capability to establish the baseline.\n- Identified the current user context as `root` to correctly interpret the `test -w` result (root bypasses DAC permissions — the bit state, not `test -w`, is authoritative here).\n- Executed `chmod 444 test.sh` explicitly to enforce read-only mode for owner, group, and others.

Exit code: `0` (success). Because the bits were already `444`, this made no changes to the permission mask but ensured the state was explicitly applied.\n\n### 3.
