Lens: L-PERFORMANCE · Density: D-MED · Axes: REL, ROB
Criteria
- Hot paths identified with anchors.
- Unbounded allocations / unbounded fan-out.
- N+1 / accidental quadratic patterns.
- Caching correctness (stale/wrong cache worse than slow).
- Backpressure / load shedding if networked.

Pros / cons
| Pros |
Cons |
| Emphasizes bounds and cache honesty |
Microbenchmark theater — require anchors |
| Caching wrongness → ROB/REL |
Without profiles, severity must stay moderate unless algorithmic proof |
