 ### Fixed

- **A query log set aside by a schema change is no longer named `corrupt`.** Every recreate wrote the old file to `querylog.db.corrupt-<unix seconds>`, whatever sent it there — including the fingerprint mismatch an upgrade causes, where the file is a healthy database this build simply cannot read. The name is the only account of the reason that outlives the log line, so it read as an accusation. This is not hypothetical: on the 0.0.6 upgrade it cost a real query log, deleted during a post-deploy cleanup on the strength of the word `corrupt`. The name now says which of the four cases it hit: `querylog.db.corrupt-…`, `.not-a-database-…`, `.quick-check-failed-…` or `.schema-changed-…`. The 0.0.6 upgrade produces `schema-changed`. Nothing else about the recreate changed, and no existing aside file is renamed.
+- **An upstream success rate no longer rounds up to 100.0% while failures stand.** One decimal place cannot hold 12,696 successes out of 12,698 attempts: it rounded to `100.0%`, so the row claimed perfect reliability next to a failure count of 2. Neither end of the scale is reachable by rounding any more — `100.0%` needs an actual absence of failures and `0.0%` an actual absence of successes, and a rate a hair off either end shows `99.9%` or `0.1%` instead.

The name is the only account of the reason that outlives the log line, so it read as an accusation and invited operators to delete an intact file.
