A write owns the record at its key when the written type declares the
record's schema id, or reads an older undeclared id of its own schema name
whole (ruling own-entry-reads-whole); every other registered type's record
is refused, in every cache, with or without a backing store
(cache-refuses-retype).
Removing a record and adding one of another type in a single batch is
staged as the held record's eviction then the add, so validators, Claim,
the store judges and the change journal see what they see staged apart
(one-batch-retype-is-eviction-then-add); Watch<old> gets Removed and
Watch<new> Added. A one-batch retype across home stores is refused by the
batch-spans rule and must be staged apart. A variant rebase changes type
exactly where a plain write may (variant-rebase-follows-plain-write).
Store kinds outside the library get one protected per-key judge
(store-kind-per-key-judge), exercised by tests/GameCult.Caching.OutsideStoreTests.

A cacheless call that writes nothing declares nothing and no written entry can claim the record, so the removal is refused and the file left as it was. Red under the Any-to-All mutant of the declared predicate in OwnsOnDisk, which owns every id when no entry is written.

The lent-shape test omitted the old id from the passed entry, so the base code refused it for the id and not for the shape. It now lists them, making the registry's wider entry the only thing that could own the record.

CatalogEntryLookup now takes the lent registry and answers from the written entries plus the registry's other types (descriptors whose schema id no written entry has). The registry Owns overload, the subset predicate and OwnsOnDisk's lent branch are deleted; the passed entry alone describes the written type, so a lent registry only adds claimants and can only refuse more.
Not yet built or run (verified by the job that follows).

The cacheless written test now holds on the entry passed: the claimant's compatible ids must all be listed by the written entry of its id.
CHANGELOG and WriteRecord's registry doc describe the refusal through another registered type's listed id, the condition on own drift, and the Shared caveat. Not yet built or tested here.

Kills the written-by-name mutant (the claimant condition compared schema names instead of ids).
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
Owns takes a condition on the claimant's answer (mayClaim): the cache arm accepts any
claimant, the cacheless arm only one of the entries the call writes. Another registered
type's record, under its current id or an old one it lists, is refused as at 0e57bf11.
Tests pin P1a/P1e/P1f shapes, the writer's own drift under a larger registry, and that a
second same-name type in the lent registry only refuses. CHANGELOG entry for the cacheless
claimant; stale comments on the store's owns predicate and WriteDocument's registry doc fixed.
Builds not yet run when committed; verified on Yggdrasil before push.

Kills the two survivors of the claimant lookup over written entries (Named inverted, Owner dropped).

ReadStore refuses a record whose schema the catalog does not publish, so the
file-level scenario the spec named cannot be built; the rule is pinned where it is decided.

CultDocumentRegistry.Claimant is now the only precedence that decides which entry
reads a persisted catalog entry, static over a lookup (a registry's indexes, or the
entries a registry-less cacheless write writes). ClaimantEntry is deleted. A cacheless
WriteDocument or WriteRecord lent a registry is never more permissive than a cache
registering the same types; an unpublished id is carried, not owned, through Owns' catch.
Fixes the four Low findings of variants:verdict:cut-restamp-on-write.s2.

Owns is now a static rule over (declared, claimantOf): a registry supplies both from its indexes, a cacheless writer supplies its one entry, so
the hand-written cacheless lambda is deleted and a renamed entry listing the writer's id is owned by both. The schema-name check is the
claimant selection and is pinned. Variant read-whole flag pinned for rewrite, flatten and remove.

Stryker found the true default and the two Wrote sets equivalent: a constructed or written record is stored under its type's declared id, so the flag is never asked. Not run at this commit.

The ForeignRecordTests read-only fixtures (another runtime's deck, the moving deck) had the same shape as the deck, which the
type now reads whole and owns; each gets a slot the deck lacks, so it is read only by dropping it. RestampOnWriteTests and the
successful-churn gate test are corrected from the first run. Not run at this commit.

CultDocumentRegistry.Owns replaces Declares as the one answer to whether a writer may write, relabel or remove a record under a
schema id: the id is declared, or the type that reads it reads it whole (equal content hash, or compatible shapes with no persisted
slot ignored). Staging asks the declared half or CultStoredDocument.StoredSchemaReadWhole; the apply halves (single file,
directory, cacheless CultMesh) ask Owns over the durable catalog, once per distinct id. A record read only by dropping slots
stays read-only until its id is declared compatible.
Not built or run at this commit: verified on Yggdrasil at the cut's head.
