"""L1: tht memory save-one -- targeted upsert via the writer key (spec D11).
|
|
|
|
The D11 deviation: instead of a full vectorstore resync (tht memory index / sync),
|
|
a remote workstation with a writer key can push a SINGLE promoted decision to
|
|
pgvector as a one-row upsert. This test pins the pure core of that behavior:
|
|
- exactly one VectorRecord is built for the chosen decision_seq
|
|
- the writer.upsert_records is called once with a single row
|
|
- writer.sync is NEVER called (that is the full-resync path)
