check / check (push) Waiting to run
internal/database now opens the database with one connection. pixa's own reads and writes wait for it in turn instead of competing for SQLite's lock, where a write that kept losing could wait past the five-second busy timeout and fail with "database is locked". The busy timeout stays, for another program writing to the same file. With one connection, a query run while rows or a transaction are still open would wait forever. No code in internal/database or internal/imgcache does that; the comment on DB() tells callers. README.md says pixa uses one connection. Model: opus-5-5
