Fields takes an optional legacy name per field, matched on read only and mapped to the same index as the current name, so a legacy and a current name in one object are the same property and the duplicate rules decide (refused when AllowDuplicateProperties is false, last wins otherwise). Writing never emits a legacy name. MessagePack bytes are unchanged.

SPIRV-Cross renames members matching GLSL builtins, so the source names change. Resolver and JSON writer accessors follow the members; the wire (positional MessagePack, JSON keys) is untouched in this commit. The committed GLSL is stale until its regeneration commit, so CommittedGlslEqualsLowering fails here.

CultPayloadDepth.Check walks MessagePack headers iteratively and refuses the first
container past CultMessagePackSecurity.MaximumPayloadDepth, read or skipped, called by
SerializeUntyped (on the bytes it produced) and DeserializeUntyped (before decoding).
UntrustedData's 500 is replaced by the same value as a backstop. CultUnionGuard refuses
[k, nil] arms. New vectors in tests/vectors/union-parity, with bounds-outcomes.msgpack
as their data; the gate now runs every Check-calling test body and fingerprints bytes

CultCache mints storedAt from an internal Clock (default the wall clock); the vector writer pins it, so
union-surface.cc is regenerated in process and byte-compared on every run. The gate test sets the switch
itself and writes only a probe, so it neither skips nor touches a committed vector.
This commit does not pass: union-surface.cc still holds the old wall-clock stored-at; the next commit
regenerates it. Builds.

EndUnsendable put the SocketException's message on the wire, the

Only "nothing at the path" reads as an empty store; a zero-byte file is Undecodable in every
runtime; a dangling link is an I/O error. Errors name keys and schema ids only, never stored
values, and echo a header only in the cultcache.store.v<digits> shape. Single-file writes
report NotReplaced / ReplacedNotDurable / Rejected; an unlock failure after a successful write
no longer replaces the write's result.

The schema server's backstop ended every session with "session refused
a packet", including when the fault was the server's own: for example a
handler's response too large to send, or a refusal the handler did not
type. Decoding and handling are now two catches:
- A message that cannot be decoded is the peer's. The session ends with
the refusal reason.
- A handler fault ends the session with "server could not handle a
message".
The transport's EndRefusedPeer becomes EndPeerSession(peer, reason). It
reports whether it ended the session, so the log says when a response
that failed after its first fragment had already ended it over the send.
Before, the log reported that it ended a session that was already gone.
The comment said that ending the session matched cultmesh-py. It does
not: Python silently skips a malformed frame. The honest anchor is the
C# TCP schema server, whose ServePeerAsync ends the one peer whose
message fails to decode or handle. The comment now says so.
Pinned, each by a test that kills its mutant:
- a handler fault's goodbye carries the server's reason, not the refusal
(mutant: the refusal reason);
- the post-fragment-0 path logs that the session had already ended
(mutant: a constant outcome);
- EndPeerSession says no goodbye to a replaced peer's endpoint (mutant:
the Ended check dropped);
- a refused peer's frames still queued are never handled (mutant: the
queue purge dropped).

3b9ffac2 claimed that the generation check subsumed the UnsendableReason
once-guard. It did not. A thread that reads the generation only after
the session has ended carries the ended session's own generation, and the
check lets it through. For example, the polling thread answers a Ping on a
session that a caller's send has just ended but that has not yet been
retired. When that Pong fails permanently, the thread says a second
goodbye and overwrites the first failure's reason (Soul pass 4, PR4).
EndUnsendableSession now also returns when the session has already ended.
Two tests:
- The polling thread answers a Ping on a session already ended, and the
Pong can never be sent. Exactly one goodbye goes out, and the first
failure's reason stands. The hook admits the Ping after the session
ended and before the peer is queued for retirement. The test kills the
mutant that drops the Ended check.
- A failed send's goodbye is sent under the gate. A polling thread
admitting a new Connect from the endpoint waits on the gate, so the old
generation's goodbye never follows the new session's Accept. The test
kills the mutant that sends the goodbye outside the gate.

RequireSingleFileFormat echoed any header string. It now names one only in

RudpCultNetSchemaServer decoded each schema frame outside its per-message
backstop, so a malformed payload (0xc1) or a well-formed message with an
unknown schemaVersion threw MessagePackSerializationException out of
PollAvailableAsync and PollOnceAsync. The drain aborted: a good peer's
request in the same drain went unserved, a consumer loop that did not
catch died, and the bad frame was already acknowledged while its peer
stayed connected.
Decoding now runs inside the backstop. A peer whose message cannot be
decoded or handled has its session ended: the transport's new
EndRefusedPeer sends the refusal goodbye under the gate, counts the drop
in PacketsDropped, drops that peer's frames still queued, forgets the
peer and raises PeerDisconnected. A session that already ended (replaced
by a new Connect, or ended by a send failure) gets no goodbye, since the
endpoint may belong to a new session. Other peers in the drain are still
served. Ending the session matches cultmesh-py's server, where one
peer's bad message ends that peer; runtime parity is the reason.
The log names the fault's type only and never its message, because the
decoder's message quotes the peer's input (the unknown schemaVersion).
The dispatch-backstop test now asserts that rule instead of the handler
message it used to require.
Tests, each failing on the pre-fix code: a malformed payload and an
unknown schemaVersion each leave the good peer served without Poll
throwing (also through PollOnceAsync); the bad peer's session ends,
counted and told; the log carries the type and not the canary value.

Send ended an unsendable session after releasing SessionGate, and the
goodbye was built under the gate but sent outside it. If the polling
thread admitted a new Connect from the same endpoint in that window, the
ended generation's goodbye reached the new client: it saw Data, Accept,
Disconnect and believed itself disconnected while the listener held it
connected.
Every path that finds a permanent send failure now reads the session's
generation under the gate at the send, and EndUnsendableSession builds
and sends the goodbye under the gate only while that generation is
unchanged. The generation check replaces the UnsendableReason once-guard:
a second failure in the same generation finds it already ended.
The test orders the new Connect inside the send, before the fragment
that can never be sent, and asserts the new client hears no Disconnect
and stays connected on both sides. It fails on the pre-fix code
(Data, Accept, Disconnect) and kills the mutant that drops the check.

The document servers' refusal tests sent an unreliable fragment, whose
sequence the session never records, so dropping the reset before the goodbye
survived. They now refuse a reliable fragment and check the goodbye does not
acknowledge it.
C#: a BeforeSend seam orders a caller's failing send between the polling
thread's ack and its send, so both threads end the same session; the peer
hears one goodbye.

A caller still holding the replaced peer (a schema handler awaiting work for
it) could send into the endpoint the new session owns: a goodbye after a
partial failure disconnected the new client, a fixed initial sequence
delivered the stale frame in place of the real one, and a drawn one stalled
the new session. The replaced session now ends under the SessionGate every
Send takes, so a stale Send throws and nothing of it leaves.

A caller-directed Send that failed after a fragment left called
EndUnsendablePeer on the caller's thread, removing from _peers and raising
PeerDisconnected while the polling thread could be changing _peers too.
Send now ends the session and sends the goodbye under the peer's
SessionGate, and queues the peer; TryReceiveOnce and PollResends retire
queued peers before anything else. A peer a new Connect already replaced
is skipped, so a stale peer object cannot remove the peer that replaced it.

CultMeshRudpSocketOptions.BindHost defaulted to 0.0.0.0 for servers and
clients alike (a58daa54, so clients could reach remote routes). That bound an
IPv4 socket for every client, so a client for an IPv6 endpoint could not send,
and a client for a loopback endpoint listened on every interface.
BindHost is now nullable and unset by default. Unset, a client binds loopback
for a loopback endpoint and the unspecified address of the endpoint's family
(0.0.0.0 or ::) otherwise, matching cultnet-rs, cultnet-ts, cultnet-py and
cultmesh-kotlin. A server keeps binding 0.0.0.0. An explicit BindHost wins for
both. The test that pinned the old default's value is replaced by tests of
what each endpoint binds.

The injected permanent failure now takes precedence over the injected transient
one, so a test can end a session on a peer that is also losing datagrams and
count exactly which datagrams were attempted afterwards. New tests: a hub
disconnect that can never be sent returns the error; a peer or session ended
in the resend loop is sent nothing more (Rust hub, document server, C#); the
goodbye reaches the peer; the Python server ends the session on a permanent
failure in a resend, an ack and an accept. The oversized-send test compares the
outstanding count with the one the hub's own unacknowledged Accept already
holds.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
The listener swallowed every send failure as a counted loss. A send now splits
into permanent (MessageSize, InvalidArgument, AddressFamilyNotSupported: the
datagram can never be sent as built) and transient (everything else, still a
counted loss). SendSchema throws the SocketException and queues nothing, with
the packets it created withdrawn and their sequences reissued; a permanent
failure after an earlier fragment left ends the session. Inside a poll the
failure ends that peer's session, PeerDisconnected carries a reason naming the
error, and the poll is never failed. Tests pin each path, the classification,
BytesSent after a healthy send and a zero failure count.

The bound summed only packets still awaiting an ack. Once frames above a lost
packet were acknowledged they stopped counting, so a receiver could be made to
hold more than 4 MiB behind one loss, and its hold buffer ended the session.
The sender now keeps the payload size of each acknowledged sequence above the
lowest pending one until the lowest advances past it, in Rust, TypeScript,
Python and C#. Tests per runtime: one lost packet, four acknowledged 1 MiB
frames, the fifth refused until the gap closes; and the floor moving to a new
lowest sequence.

Cut 1: one watermark owns ordered delivery, seeded only by the handshake.
Cut 1b: every ending drops what the session still owed; flush is bound
to its generation. Cut 1c: a Connect repeats only by its sequence;
stale data and stale Connects are handled as TCP does (challenge Ack);
an unanswered attempt retries at +window-1; the session draws its
initial sequence. Wire bytes unchanged in all four runtimes. Five Soul
passes. Public option types changed: initial_sequence is optional.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
While a Connect awaits its Accept, only an Accept the client honours retires it. An Ack that names the Connect (a server's reply to a repeat or a stale copy) no longer wedges the client with nothing to resend. The Connect payload lives on the session, so a fresh attempt can always be built. The fresh attempt uses the abandoned sequence plus the receive window less one (serial), so a late copy of the abandoned Connect stays inside the new one's stale window; only a session's first Connect draws at random.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
A frame at or before the seeded watermark is a duplicate of an earlier generation and is acknowledged, never delivered again (serial compare within the receive window). A Connect that precedes the current generation's within the window is a stale copy of an earlier attempt: it is answered like a repeat (Accept owed or Ack), changes no state and does not refresh liveness. A Connect unanswered for 3 s is replaced by a fresh Connect with a newly drawn sequence and the same payload. In server mode a Connect from another endpoint is always a new generation. The initial sequence is unset by default and each session draws its own; the public random helper is removed.
An accepted peer now stamps its liveness on accept, so one that goes silent times out.

F1: RecordUnappliedEntry keeps the primary's wire entry on the in-memory log
entry (internal Relayed) and ToLogEntryMessage returns it through the same
normalisation the store uses, so a replica with no store no longer relays a
skipped put as a delete; memory and disk relay identically.
Soul's 4d probes are committed (chained replica keeps the row, key-prefixed
reads serve only owned keys, primary-all serves everything; the two
measurements are explicit) with a memory/disk relay-parity test.
Rust: captured-bytes cases for unowned_schema and variant_unsupported (with and
without a subscription).
The error-code set is stated as a closed enum in the schema description (both
copies) and in cultnet-distributed-database.md: adding a code is one
coordinated change across runtimes, since Rust and TypeScript refuse an unknown
code. The Soul 4c probe file's header says what it guards.

A bounded session whose queue still held an unacknowledged Accept for a peer
that vanished refused the next Connect; the old server-mode path reset before
accepting, so this would have been a regression. accept_connect and
create_connect now end the generation first in every runtime, and a test per
runtime holds a one-slot queue to it.

The dispose test showed journal-first alone still lost the change: Dispose won the race against the writer's publication and cleared the stash. Dispose now drains the stash through the publisher after the journal is disposed (so nothing is stashed afterwards) and before the subject completes.

Q1: HandlePutAsync/HandleDeleteAsync catch a CultNetShardLogException (or an
AggregateException holding one) before the generic catch and answer nothing: the
write committed and was published, so the peer is not told it was refused. It is
logged at warning level. The wire has no committed-with-degraded-log message.
Q2: GetAsync/GetAll/GetByName/GetByIndex, the shard-less snapshot, the selection
and the subscription snapshot serve only rows a shard owns, so read and watch
agree; the CultMesh collections follow through GetAll, and the Mesh untyped
variant fallback checks ownership. The raw cache still holds everything.
Q3: a replica log apply skips a row its shard does not own, as the snapshot path
does, and still records the entry so a chained replica sees no gap.
API: rowFilter is internal (public CreateSelectionResponse and
CreateRawSnapshotResponse signatures restored, internal overloads added);
exception tags on the write methods; Commit's unwrap rule is XML doc; the
unowned refusal answers on the wire with code unowned_schema (schema enum in both

delete log it at warning level.
Dispose keeps journal-first; a test now fails if the observer goes first.

The session records the sequence of the Connect that started its generation. A
Connect repeats exactly when the session is connected and carries that
sequence; anything else ends the generation, forgets the peer and accepts a new
one. AcceptConnect answers both, ConnectRepeats is the predicate for servers
that keep one session per peer, and AnswerRepeatedConnect is private. Server
mode admits a Connect from a new endpoint and the session decides; the listener
no longer compares payloads (the payload stays application evidence).
CreateConnect on a session that has had a peer starts a new generation. An
Accept counts only while the Connect is pending and only if it names it. The
watermark is seeded by the Connect or Accept alone; reliable data before that
is neither remembered, acknowledged nor delivered. The default initial sequence
is random in [1, 2^31) in every options type. An ICMP connection reset no
longer sets DisconnectReason: nothing ended. The interop peer flushes before it
disconnects.

ResolveShard now throws for an unowned schema, so one such cached row would
have failed the whole selection. The server passes a row filter
(CultNetDatabase.Owns) to CreateSelectionResponse, which gains an optional
rowFilter that SelectPage already took, so those rows are not part of what the
database serves and the rest is answered.

ResolveShardInternal throws CultNetUnownedSchemaException instead of falling
back to the first shard. PutAsync, DeleteAsync, PutPredictedAsync,
ApplyPutAsync and ApplyDeleteAsync refuse an unowned schema before the cache is
touched; a remote put reaches the server's generic catch and is answered as an
application rejection like any other refused remote put. ResolveShard throws
(documented), CanWriteAuthoritatively returns false, and a bare cache write no
shard owns is neither logged nor published. The unused string overload of
EnsureClientAuthority is deleted. No GameCult consumer configures shards
outside vendored CultLib copies; the default shard owns everything.

PutAsync and DeleteAsync carry no door, so the journal cannot place an unowned
schema and now skips it; accepting the write anyway was a silent loss of
replication. They resolve their shard strictly and throw
CultNetUnownedSchemaException (an InvalidOperationException naming the schema)
before the cache is touched. Doors keep the fallback shard they were resolved
to. No GameCult consumer configures shards outside vendored CultLib copies:
AetheriaEve's node uses the default PrimaryAll shard, which owns everything.

F1: InitializeLogSequencesFromStore raises the in-memory floor to the highest
gap above the store's compaction point, so a restart after a double refusal or
an interrupted compaction answers compacted_history instead of a gapped log.
F2: the journal raises one CultNetShardLogException per call carrying every
burned (shard, sequence); the unwrap rule for a cache-aggregated hold is
documented on the exception and on the cache commit.
F3: TakeDoor no longer refuses a door whose instance is the cached one, so
mutate-then-predict publishes Predicted and is not logged.
F6: a door-less change no shard matches is not logged; doors keep the
fallback shard they were resolved to.
Dispose disposes the journal before the observer. The log store doc says a
