**Server-side display caches are disabled for the suite, never waited out.** A test that changes state the server serves from a TTL cache must not poll until the TTL expires - that burns the TTL in wall-clock on every run (the leaderboard ranking test cost 60s and the Code Farm saturation test 30s exactly this way). Each such cache reads its TTL from an env var with the production value as the default, and `conftest.py` sets it to `0` before the server subprocess starts: `DEVPLACE_SITEMAP_TTL` (`seo.SITEMAP_TTL`), `DEVPLACE_HOME_CACHE_TTL` (`main._home_cache`), `DEVPLACE_RANKING_TTL` (`database/ranking.py` `_authors_cache`), `DEVPLACE_MARKET_SATURATION_TTL` (`services/game/store/market.py` `_saturation_cache`). Add a new display cache to that list rather than sleeping in the test. **Correctness caches are different**: the cross-worker `cache_state` version read (`_cache_version_cache`, 1s) is load-bearing and stays on, so a test that flips the admin set from the test process must wait for the server to agree before asserting (see `tests/e2e/admin/containers/manage.py` `_await_instance_visible`), never assume the change is instant.

The loop: `make test-fast` -> fix -> `make test-failed` until it is empty -> `make test` as the final gate. `make test-first-failure` is only for the rare case where one early failure poisons every test after it (a corrupted session fixture, a stopped service). Pytest's cache lives in `.pytest_cache/` (git-ignored), so `--last-failed` works with no extra setup; do not pass `-p no:cacheprovider` in a run whose failures you intend to re-run. **If `make test-failed` runs the whole suite instead of just the failures, the cache is polluted**: pytest keeps `lastfailed` entries for tests it did not collect, so node ids from deleted files (or from a stray `pytest` invocation that walked `data/`/`var/`) linger forever and make `--last-failed` give up and select everything. `make test-cache-clean` drops `.pytest_cache/` and fixes it; `make clean` does it too.
