# hephaestus hub (server mode) on indri.
#
# DATA SEEDING (one-time, Path A — do this BEFORE the first provision so the hub
# adopts gilbert's existing data instead of being born empty):
#
#   1. On the seed device (gilbert):   heph daemon stop
#   2. Copy its store to indri:         scp ~/.local/share/heph/heph.db \
#                                           indri:~/.local/share/heph/heph.db
#   3. On indri, give the hub its OWN device origin (keeps gilbert's owner_id +
#      data; hephd regenerates a fresh origin on next start when it is missing):
#        sqlite3 ~/.local/share/heph/heph.db "DELETE FROM meta WHERE key='origin';"
#   4. Run this role (installs hephd, stages the PWA, loads the launchagent).
#
# hephd auto-creates an empty store on first start if none exists, so seeding is
# optional — skip it only if you intend a fresh, empty hub.
