 # Completed Steps
 
+- 2026-10-04 `TestEvictionRunsOnPeriodicSchedule` no longer races the evictor
+  (closes #183): it wrote each variant file and then inserted its accounting row
+  by hand, and a reconciliation pass between the two adopted the file first, so
+  the insert failed. It now writes the files only, while holding the test
+  database's only connection so the evictor's startup pass waits after walking
+  the empty variant directory; a periodic reconciliation pass then adopts the
+  files and the eviction pass after it evicts them. No other test in
+  `internal/imgcache` inserts a row by hand after starting the evictor. Test
+  only.
 - 2026-10-04 deployment guide and example Caddy config (closes #89):
   "Deployment" in `README.md` says what the reverse proxy in front of pixa must
   do (terminate TLS; pass `Host`, `Origin` and `Referer` on unchanged; set
