O(n²) AddUniqueFinding In Safety-validator.service.ts

Every time a new finding is added in line 347 of safety-validator.service.ts, the helper runs a full linear scan through the existing array - causing a brutal O(n²) hit when adding n findings. This slowdown isn’t just slow - it’s a bottleneck in real-time safety checks. Think of it like checking every email twice to avoid sending duplicates: inefficient and risky under pressure. The current logic scans the array each time, re-checking every entry. This creates unnecessary strain, especially when hundreds of safety findings pile up.

This pattern reflects a broader trend in modern coding: rushing fixes without considering scalability. In user-facing tools - from fitness trackers to mental health apps - latency creeps into trust. A delayed safety validation isn’t just annoying; it’s a silent risk.

Here’s the core issue: every addition triggers a full array search, not just a smart lookup. The fix? Replace the array check with a Set. Storing findings in a Set cuts lookup time to O(1), slashing complexity to O(n) for adding n items.

The cultural shift here isn’t just technical - it’s about responsibility. With safety-critical systems, we can’t afford quadratic slowdowns. Developers must prioritize data structures that scale.

But there’s a catch: replacing the array means losing direct index access, and duplicates must be handled explicitly - no auto-ignoring.

The bottom line: O(n²) addUniqueFinding in safety-validator.service.ts isn’t just slow - it’s a vulnerability. Switch to a Set. Your app’s speed, and your users’ trust, depend on it.
