_projectRecord (CultNetDatabaseSubscriptionServer.cs) reached no production
caller and ran after authorization with no wire consumer. Removed the field,
constructor parameter, and both call sites in Watch() and
CreateProjectedSnapshot(); projection is a value on a v1 selection now, not a
delegate. The two tests that used projectRecord to simulate a record's
identity changing for the reconcile diff
(DatabaseSubscriptionServer_AuthorizesRequestAndFiltersSnapshotAndLiveRecords,
…ReconcilesDeliveredProjectionAndBodyDemandWhenAuthorityChanges) are rewritten
to drive a real rename through the database (delete the old key, put the new
one) instead, so they still prove authorization filtering and the Reconcile()
diff/body-demand behavior.
Self's ruling (docs/cultnet-selection-cut.md, 2026-09-22): the fourth
schema-matching copy at CultNetDatabase.cs, serving CreateShardSnapshotResponse
and SchemaMatchesCatalogFilter (MatchesRequestedSchema + a duplicate
InferSchemaName), collapses into CultNetSchemaAliasMatching.MatchesAny, the one
matcher landed in commit 1.
Networking tests: 162/162 (was 162/162 after commit 1; no count change, two
tests rewritten not added). Negative grep: _projectRecord|projectRecord empty;
MatchesRequestedSchema gone (one remaining substring hit is
RawSnapshotPayloadMatchesSchema in CultMeshSnapshots.cs, the Mesh copy this
commit does not touch — collapses in the next commit).
Mesh collapse (§4/§11 of the map, ~365 gross lines across CultMesh.cs,
CultMeshSnapshots.cs, CultMeshClient.cs, CultMeshBodyDemand.cs) is not in this
commit; it is large enough to build on its own and follows as commit 2b.
