# Reconcile Trajectories

`POST /api/trajectories/reconcile`

Mark server-side trajectories as archived when the local
client no longer has them. Trajectories are append-only history
— the file on disk + summary + DB row are NEVER deleted, just
flagged with `archived_at`. The default list endpoint hides
archived; pass ?include_archived=1 to surface them again.

cloud_sync calls this once per sweep with the full list of
session_ids it sees on disk; anything the server holds for the
calling user that isn't in the list (and isn't already archived)
gets archived. Re-syncing a session that was previously archived
re-activates it (clears archived_at) — useful when a user
restores a trajectory locally.

Body: {"session_ids": ["...", "..."]}.
Scope = the caller's owned trajectories only.
