docs/cultnet-selection-cut.md section 6/7/10: the reflection loop at
CultNetDocumentRegistry.cs:325-342 exists only because nothing outside
GameCult.Caching can read a declared index value, reference, or numeric
member (Members/IndexAccessors are internal, no InternalsVisibleTo to
Networking). This adds the one public door instead: CultDocumentMemberView,
CultDocumentDescriptor.DeclaredMembers/TryGetIndexValue/TryGetIndexNumber/
ReferencesOf, and CultDocumentRegistry.ResolveTargetLeaves (D9, computed live
against the registry, never cached or persisted).
Two registration refusals land beside DiscoverMembers' existing
DuplicateSlotMessage/HiddenMemberMessage: D10 renames the ArgumentException
ToDictionary already threw for two differently-named members sharing one
index alias into a rejection that names the schema, both members and the
alias; D11 refuses a reference member whose CLR shape the cache cannot walk
(many:false needs CultRecordRef<T>, many:true needs
IEnumerable<CultRecordRef<T>> or IDictionary<CultRecordRef<T>, V>) instead of
silently answering it as unreadable later.
GameCult.Networking is untouched; the evaluator that will read this surface
does not exist yet (commit 1).
Verification: dotnet test tests/GameCult.Caching.Tests - 188 passed (176
existing + 12 new), 0 failed. New tests: TryGetIndexValue/TryGetIndexNumber
reading an inherited alias; ReferencesOf over a single/many-list/many-dictionary
reference, including two dictionary entries with different payload bytes
(S19); ResolveTargetLeaves against an abstract target with no [CultDocument]
of its own (D9), including a leaf registered after an earlier descriptor was
built; IsNumeric agreement for a nullable numeric and a decimal member (S22);
the two new registration refusals, dynamically emitted so registry discovery
by attribute scan cannot see the rejected shapes.
scripts/mutate-cultnet-selection-caching.ps1: a dedicated dotnet/NUnit
mutation runner (the shared tools/eureka-mutations.ps1 harness only speaks
cargo; scripts/mutate-cultmesh.mjs is the QUIC campaign's file and this
campaign does not edit it, per the map's section 10). Byte-exact restore
verified by SHA-256, a sidecar for crash recovery, M0 no-op control, one
anchor match required per entry. Six entries (D8/S22, D10, D11 - revert and
loosening each) all KILLED; final restore verified green.
