Why:
- The failure modes worth testing are races, and they are cheap to force
against the fake and expensive to observe anywhere else.
Changes:
- Unit tests for both boundaries, the repeat delete, a missing neighbour, the
traversal property after several deletes, and — via a repository that bumps a
rival's version before each apply — both the partial-apply repair and the
unconvergent 409.
- One new shared contract scenario (a multi-point batch applies every patch,
including nulling a pointer) so it runs against the fake and real Qdrant.
- HTTP tests against real Postgres and Qdrant for relinking, soft-not-hard
delete, cross-tenant 404, and scope enforcement on both routes.
- create_source_file factory for tests addressing a file without uploading.
