Downloads official instruction PDFs from LEGO, located via the Brickset API, one set per interval (10 minutes by default) so neither API gets hammered. Official sets only; MOCs are excluded throughout.
- New admin page at /admin/instruction-fetch: queue builder, pacing controls, live countdown and per-set job history
- Database-backed queue (instruction_fetch_jobs) and last-run timestamp, so pacing survives restarts
- Background worker thread, plus 'flask instructions queue/run/status' for Task Scheduler or cron
- SHA-256 dedupe (instructions.sha256), PDF header check, size cap and streaming downloads via temp files
- brickset_api: getInstructions2 by set number and getInstructions by setID (the old code sent a set number to the setID method); getSets params now proper JSON; getKeyUsageStats added
- Schema top-ups applied automatically at boot: new table plus instructions.sha256/source
- Docker: fetcher env vars passed through compose, no worker thread in the entrypoint bootstrap
