Early in development, the main question was whether a button worked. Once the application was in use, keeping existing tabs, unsent text, logins and projects across an update became a larger concern. Preserving current work became part of the completion criteria for a new capability.
An installer finishing does not establish restored work
A clean installer exit and a new version number do not establish that the user's workflow returned. Tab IDs and destinations, selected projects, drafts and settings are not encoded in the executable's version string. Checking program files cannot establish preservation of user state.
Historical comparison evidence separately matched the installed app.asar to the verified package hash and compared workspaces, tasks, settings and tabs. File identity and continuity of work were different questions. Separating them exposed what a simple installation-complete report was missing.
An old backup can overwrite newer work
Capturing state before a test does not make that capture the correct recovery target forever. The user can change tabs and add conversation messages during verification. In the actual record, the later tab and message state was retained instead of reverting it to the initial snapshot.
This is not an argument against backups. A backup is evidence from a particular time; restoration changes the present. Whether restoration is needed and which time should be restored are separate decisions. Preservation cannot mean forcing every current count to match an older number.
Even reloading the same destination can discard work
Finding an existing tab and then loading its same destination can erase unsent input and page-local state. The reuse rule adopts a matching URL without an unnecessary reload. It distinguishes that from a genuinely new navigation such as a different search query.
An explicitly selected tab that is closed or belongs to another project is not silently replaced with a similar tab. Avoiding a new tab does not authorize arbitrary reuse of another manuscript. Preservation includes refusing to change the work target for an invisible convenience.
User state and live element references have different lifetimes
Restoring a tab does not keep its old element references valid. Restart creates new web contents and documents that require fresh observation. Retaining a destination and work history differs from reusing a reference that once supported a click.
The comparison report also distinguishes a restored destination from native back-navigation history, which can reset after restart. Public explanation should not let one word, restore, imply perfect reproduction of every internal state. It is more precise to record which values were preserved and which require fresh observation.
Keep preservation evidence alongside feature evidence
Historical generation and download checks on existing tabs compared tab ID sets before and after, separately from the feature result. A download replay checked the same hash without repeating the entire generation. Verification itself should not unnecessarily repeat work being preserved.
That record is not a guarantee for every account or future update. It concerns the tested version and the tabs and projects present then. A successful feature screenshot cannot explain whether existing work changed. Before-and-after state and the exact replay scope make the evidence useful for the next change.
Readiness becomes visible on the next day of work
Customers need more than a list of new capabilities. They need to continue yesterday's input and spend less time logging in again or reconstructing manuscripts after an update. Explaining the improved feature together with the preserved workflow conveys the application's practical value.
I did not reinstall the running app or close user windows for this article. The account uses existing installation and preservation records and the current reuse contract. Future changes should likewise retain separate evidence for installed files and user state, making it possible to check that an improvement did not displace existing work.
