Delete Hidden, HiddenProblem, UnreadKeyedMembers/UnreadMembers, Settle's
[MessagePackFormatter] refusals and the door's written-as-object branch.
Classify gains Leaf for attribute-formatted, [DataContract] and string-keyed
types; MembersOf honours the most derived AllowPrivate; the door refuses a
null StandardResolver formatter with the throwing path's text.

WrittenAsWalked required StandardResolver's formatter to equal one of the walk's own families, which refused every source-generated formatter. WrittenAgainstWalk asks one contrary resolver per walk kind and refuses only on a reference match. DcSeq is refused as a collection written as an object; FormattedRoles passes (registration owns the attribute).

EnumeratesObjects took ElementTypeOf first, which for a dictionary is the
KeyValuePair (a leaf), so a keyed Dictionary subclass never reached the path; the
map's value type is asked first. The unreachable null-standard guard in
WrittenAsWalked is removed. Tests pin the direction and wording of the refusal, the
attribute-formatter collection case and the unwrapped inner exception.

CultElementIds is the walk's model of a type; MessagePack's StandardResolver owns how
a type is written, and nothing checked that the two agree. ResolverClaim now asks,
for each id-path type, whether StandardResolver's formatter is the object or union
resolver's (a type read by key) or a collection resolver's (a collection), and refuses
the document at first encode or decode when it is not, naming the type. A keyed type
that enumerates objects goes on the path so a keyed List subclass is caught. A type
MessagePack cannot build a formatter for, and a resolver ahead that throws, are typed
refusals; the AllowPrivate catch is pinned (s4: keyed-enumerable-misclassified,
allowprivate-catch-unpinned).

MembersOf is now MessagePack's StandardResolver write set: public fields and
properties with a public getter, none of them [IgnoreMember]. UnreadKeyedMembers
(renamed from NonPublicKeyedMembers) is every other [Key] member, including a
public property whose getter is private. IdProblem takes id candidates from every
instance member up the base chain, refuses an id MessagePack does not write, and
refuses a property id with a non-public setter, which MessagePack writes but does
not read back (s4: walk-member-set-differs, private-setter-id-dropped-on-read).
An oracle test pins the member set to MessagePack's ObjectSerializationInfo.

Classify tested IEnumerable<T> before [MessagePackObject], so a keyed class that
enumerates itself recursed until the stack overflowed during registration (s4,
keyed-enumerable-misclassified), and a keyed class that merely enumerates had its
keyed lists neither judged nor minted. Keyed first: MessagePack writes both by key.
VisitMemberType also stops at a type already on its own through chain, which ends
an unkeyed Node : IEnumerable<Node>.

No fixture makes StandardResolverAllowPrivate throw when asked for a formatter (Stryker: the catch stays
NoCoverage), so the test pinned nothing the claim tests do not.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
Stryker found the primitive, enum and object tests in Classify redundant with the value-type and unkeyed
branches, so they are gone. The new tests kill the survivors that were behaviour: a nullable keyed struct
walked as its struct, an unannotated struct treated as a value, [MessagePackObject] reaching a subclass,
and a claim on a type StandardResolverAllowPrivate cannot format.

It writes the [Key] layout plus non-public keyed members, and registration now refuses any of those that
reaches an object list, so no element id can be dropped. The comparison is made lazily, only after an
ahead resolver returned a non-standard formatter, and an exception from it reads as not equal.

MessagePack writes a non-public [Key] member only under AllowPrivate, and the element-id walk reads
public members, so the ids such a list holds could never be checked. Graph entries carry Hidden; a hidden
list or a hidden edge whose child reaches adds one problem and nothing to the id path.

IsLeaf, IsObjectType and DictionaryValueType are deleted. Classify(declared) says Leaf, Map
(IDictionary<,> or IReadOnlyDictionary<,>), Sequence or Owner; a keyed struct is walked as an owner and
is never an element. Plan and Holds take the declared root type and follow declared member types, so a
member declared object or a subclass's extra members under a base-typed member are neither minted into
nor read. Minted path text is unchanged.

Graph edges and lists carry the collection types between member and child; Settle adds them to the path so
[MessagePackFormatter] on a collection class and a resolver claim on List<Elem> are judged. Declares replaces the four
MemberInfo.IsDefined member reads, which ignore inherit for properties. Survey.Judged dedupes the unkeyed-element refusal.

Stryker survivors on the id-path walk: dropping the union-subtype edge, dropping the
element base from the path. Both now have a test that fails without them.

The single-file store records, per pull, which plain records decoded holding a non-empty
element id and at what version. A write whose copied record is still at that version
marks the header (v3). The record is positive-only and version-gated, so nothing a load
records can unmark a store. The directory store passes false: only C# writes it.

Registration: a concrete element type of an object list that is not keyed, and
[MessagePackFormatter] on any type or member on the id path or on the id member, are
refused. The id path is a fixed point over the walk's edges. The codec refuses, once per
document type and on every encode and decode path, a resolver ahead of StandardResolver
that formats a type on that path. UnionArmGuardTests moves StubArm out of the list union.
