- program B attaches to running program A's persistent database via an
IPC string in B's wo.toml [connect.<name>]; A registers clients by
name with read / read+write rights in its [share] manifest section;
unregistered = refused at connect, under-privileged = catchable trap
- doctrine preserved: A stays the single writer -- B's statements
execute inside A through the same choke-point row API, B never
touches A's WAL or slabs; typed statements checked by B's compiler
against A's table shapes, schema handshake at attach
- four forks recorded for the spec: channel carrier (lean: unix
socket + SO_PEERCRED), how B's compiler learns A's shapes (lean:
project reference + live handshake), grant granularity (lean:
whole-db rights, name+uid identity), blocking semantics (lean:
blocking round-trip, stop-flag rule applies)
- acceptance sketch: employee sample as A, a thin employee-report
client as B (read-only GroupBy over the wire) + audit-log writer
exercising the rights matrix
- slots after 9b (shares its typed surface), before 10 (HTTP is the
external face; this is the writeonce-native one); prior art:
04-client-api.md wire protocol + the WAL's value encoding
- roadmap + status board rows added
