📝 WalkthroughWalkthroughThe application adds browser-local app-preview protection and an optional six-digit PIN lock. It adds pre-render coverage, lifecycle locking, PBKDF2 verification, cooldowns, online recovery, accessible lock-screen interfaces, tests, and updated architecture and product documentation. ChangesApp protection
Estimated code review effort: 4 (Complex) | ~60 minutes Mergeability Score: 🟡 Moderate · up to PIN unlock, PIN management, and protected-access recovery can become permanently unavailable after an operation fails; recovery may also leave cached finance data behind or hang indefinitely. These bounded availability and data-cleanup risks require owner awareness and should be fixed or explicitly accepted before merge. Sequence Diagram(s)sequenceDiagram

There was a problem hiding this comment.
If two tabs run recovery concurrently, a failing recovery unconditionally restores its previously captured generation over the newer generation from a successful recovery. This revalidates pre-recovery responses, allowing one to repopulate the finance snapshot after the successful recovery deleted it.
How this was verified: The restored value is written without comparing the current shared generation, while cache writes accept any response whose captured generation equals that shared value.

| if (!persisted || generation.current !== requestGeneration) return; |
There was a problem hiding this comment.
When another tab rotates the cache generation during recovery, this provider retains its mount-time generation and its next cache write returns false. acceptFinanceResponse then returns without dispatching success or failure, leaving the tab at “Wird aktualisiert …” and rejecting every later refresh until reload.

There was a problem hiding this comment.
When one tab verifies the current PIN and another tab changes it before confirmation, the open management flow remains authorized and replacePin commits a replacement without checking the now-current credential. The first tab can therefore overwrite the newer PIN using verification obtained against the superseded PIN.
How this was verified: Cross-tab updates replace the provider credential without resetting the dialog stage, and replacePin commits the new verifier without calling current-PIN verification.

Greptile Summary
The PR adds optional lifecycle-based preview protection and a local six-digit PIN lock, including cooldown, recovery, cross-tab coordination, and early pre-render covering.
Confidence Score: 0/5
The PR is not safe to merge until recovery generation races, cross-tab refresh invalidation, and stale PIN-change authorization are corrected.
Concurrent recovery can revalidate pre-cleanup cache writes, generation rotation leaves other tabs permanently unable to complete refreshes, and an open PIN-change flow can overwrite a credential changed in another tab without verifying the active PIN.
