through `db changes`. As a staged network path, `geth db sync <node-id> <name>`
uses the protected Iroh control ALPN to request remote typed change batches when
the caller has `db.sync` on the remote `resource:db:<name>`. The requester
checks remote schema metadata against its local DB before advancing its
per-peer/per-DB cursor. Loading cr-sqlite and applying remote changes through
`crsql_changes` are future work; the current path exchanges and cursors changes
but does not mutate the local application database.
checks remote schema metadata against its local DB before applying changes and
advancing its per-peer/per-DB cursor. Compatible remote batches are inserted
into the local `crsql_changes` table or view before the cursor advances.
Loading/configuring the cr-sqlite extension for real application databases
remains the database owner's responsibility; the bootstrap tests use
deterministic fixture tables.
`geth-kv` currently provides a SQLite-backed local fallback for named KV stores
through `kv create/set/get`. `kv set --subject <principal>` evaluates local auth
