What's Changed
Everything in 20260526_02_test, plus:
New (opt-in) feature: Firmware Collector
This release ships the new 60-firmware-collector Rinkhals app. It is disabled by default. You must enable it explicitly before it does anything.
What it does when enabled: Once per day, asks Anycubic's OTA server whether new firmware exists for your printer model, using the printer's own existing device certificate (the same one your touchscreen "Check for updates" uses). If a new firmware is announced, sends just the public CDN URL and version metadata to the Rinkhals community firmware archive at https://ingest.firmwareforge.org/v1/notify so we can produce Rinkhals patches sooner.
What it never sends: device certificate, account, deviceUnionId, print history, gcode, settings, or any personal information. The full disclosure is in the app's README and shown when you enable it.
Why this exists: Today the central Rinkhals firmware monitor sees only what Anycubic advertises to a single Kobra S1 in the US. Opt-in printers across different models and regions spread out the discovery surface so we catch new firmware faster.
How to enable: Touchscreen UI → Apps, or touch /useremain/home/rinkhals/apps/60-firmware-collector.enabled over SSH.
