The container ran Obsidian Sync in pull-only mode, so notes, tasks and journal
entries the agent wrote stayed in its local copy. OBSIDIAN_SYNC_MODE now
defaults to bidirectional (merge on conflict); pull-only and mirror-remote
remain available.
Blue and green share the vault volume, and two sync clients writing one vault
and its sync state would race during a deploy. Setup and sync now run under a
flock on a file in the vault, so a new container starts syncing only after the
old container's sync process exits. Clearing Obsidian's stale sync lock is safe
inside that lock. Setup runs in the background, so startup no longer waits for
Obsidian login.
