| 1 | """Tier 4 — Stress tests for the clone browser (issue #17). |
| 2 | |
| 3 | Verifies correctness and response-time bounds under large data volumes. |
| 4 | Timing bounds are measured with ``time.perf_counter`` — no pytest-benchmark |
| 5 | dependency. All thresholds are conservative multiples of observed median |
| 6 | times so they remain stable under CI load. |
| 7 | |
| 8 | Cases: |
| 9 | S01 List page renders correctly with 500 clusters — response < 500ms |
| 10 | S02 Detail page renders correctly with 300-member cluster — response < 300ms |
| 11 | S03 Dashboard clones card query is fast with 10 000 total clusters — < 500ms |
| 12 | S04 Tier filter over 500+500 clusters returns correct subset — < 300ms |
| 13 | S05 File breakdown with 50 distinct files in one cluster — no truncation |
