Field technicians on the SHARD-24 traverse log ice-core custody in FIRNLINE, the Android app attached here. Open a station link at the address below and set it as the Station URL in the app's Settings; the custodian's release entry on your station is sealed. Thaw the vault.

FIRNLINE field client 3.2.0

Field technicians on the SHARD-24 traverse log ice-core custody with FIRNLINE. The app keeps working offline and syncs with the station whenever it can reach it.

Setup

1. Install firnline.apk on an Android 6.0 or later phone or emulator (arm64-v8a or x86_64), for example adb install firnline.apk.
2. Open the station address from the challenge page in a browser and press Open a station link. Open Settings in the app and set the Station URL to the link it shows (https://.../s/<link>/).
3. Tap Sync. The first sync enrolls the device with the station.

Your link is your station alone: keep it within your team. Point the app, or anything you write, at it. Scripts can open a link with POST /session and Accept: application/json. A link closes after about three hours without traffic; a new link opens a new station.

The station keeps a limited number of devices and forgets the one that has been quiet longest. A forgotten device gets 403 unknown device; enrolling again with the same install id brings it back. The app does this by itself.
