Restart over a retained log resumes above its highest sequence and reads its
latest from the durable log; put and delete doors log their own wire messages
and change kinds; a reconciled put is logged as an update; a replica's
watermark follows the primary's sequences; an admission racing disposal logs
nothing.

The reentrant apply test now asserts the nested call completes without
throwing: a re-recorded sequence used to be swallowed by the subscriber's
handler and hide a non-replacing in-memory log. The store-writes-cache probe
writes once, so a cache that let the journal re-enter it fails the test instead
of recursing until the host crashes.

The salvaged S1 and in-place re-upsert tests also asserted the delivery order
of the rejected drainer. Under Q-P1 A delivery order across threads and a
nested write's depth-first delivery are not guaranteed; each change is
published once with its own context, and wire peers drop stale changes by
Sequence (Cut 6). Both assertions now say exactly that. The journal tests'
reentrant-write recorder subscribes before the handler that writes.

Cut 4b-4d of the publication map. The reorder buffer, drainer, prediction gate
and the logging inside the Watch handler are gone. The database registers the
Watch observer, then one cache journal. The journal runs under the gate in
Sequence order: it takes the door, decides the change kind and prediction
bookkeeping, logs (a primary mints, a replica records the primary's entry) and
stashes the change; the Watch observer publishes the stash entry by Sequence.
A primary that cannot log a committed change burns that sequence, raises its
own compaction floor, tries CompactThrough, and throws CultNetShardLogException
(not an InvalidOperationException) after publication. A replica's refused
append reaches the pull loop and the cursor does not advance.
Fixes four defects the map named: the log is appended to disk before memory
(and memory is a SortedList keyed by sequence); the snapshot reads its log
sequence before its documents; a restart resumes above the compaction point;
GetCompactedMutationLogSequence and GetLatestMutationLogSequence honour the
in-memory floor. The snapshot removal door sets Removal.

A stray, malformed, foreign-id or refused datagram is dropped and counted,
never fatal; a refused reliable frame ends the peer's session instead of
being acked and lost; flush fails once its session ends; one reliable
Accept per session; the TS operation service expires idle sessions and
survives a throwing handler. Four Soul passes; session-generation and
reconnect semantics move to the ack cut.

Also adds a swept-after-handler test for the operation service and states
the Rust receipt comment exactly: only a peer Disconnect invalidates receipts.

The repeated-Connect answer applies its acknowledgement field in every runtime;
no test failed when a runtime stopped doing so. The TS replaced-peer test now
lets client A receive its Accept before A sends.

A Disconnect left the session's pending writes and scope alone, and the
transport's Invalidated status leaned on disconnect_reason, which connect()
clears. After a reconnect the receipt returned to Pending and could become
Acknowledged in the new session. The session now rotates its scope and drops
what it still owed on Disconnect, so the session is the one owner of
Invalidated and the transport override is gone.
A flush records the session scope it started in and fails when a Connect that
replaces the peer rotates it, instead of resolving on the emptied queue.
Tests: Disconnect-then-reconnect receipt, stale end reason after a new Connect
is accepted, flush across a replaced peer, and a repeated Connect's ack field.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A server-mode transport treated a Connect from a new endpoint as a repeated
Connect once the session was connected: the new client got an Ack and never an
Accept, and the old session never ended. Only a Connect from the accepted
endpoint repeats; another endpoint resets the session and gets its Accept.
A flush recorded nothing about the session it started in, so a disconnect
listener that reconnected cleared the end reason before the 5 ms poll saw it.
Sessions now carry a generation; a flush fails if its generation ended.
The operation service's idle sweep deleted a session whose handler was still
running, losing the response. A session with a handler running, or one that
finished a handler within the idle window, is not idle.

The hub test counts replaced sessions, since a fresh session repeats the same
Accept sequence and the distinct-sequence count could not see it. The TS test
requires an Ack, not a new Accept, once the Accept was acknowledged. A peer
Disconnect is pinned as an ended session for flush and receipts.

AddJournal runs under the gate right after Apply, once per admission that
changed something, before observers. Soul: merge with follow-ups; the

FlushReliable throws for writes an ended session forgot. A server-mode
transport and the listener answer a Connect from the peer they already hold
with AnswerRepeatedConnect: the Accept still owed, or an Ack, queueing
nothing. The listener replaced the peer session on every Connect, reusing
sequences and never reporting PeerDisconnected; it now replaces only on a
different connect payload and reports the old peer, as the Rust hub does.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
flush now rejects for writes an ended session forgot. acceptConnect on a
connected session delegates to the new answerRepeatedConnect, so a repeated
Connect re-sends the Accept still owed, or an Ack once it was acknowledged,
and queues nothing; the operation service no longer builds a session per
Connect. The operation service dropped sessions never, so 64 abandoned
clients locked every new one out: a session idle for sessionIdleTimeoutMs
(default 30 s, the document server's session_idle_timeout) is now dropped.
A request whose handler rejects ends its session like a transport refusal,
so the invoker learns promptly and a retransmit is not acknowledged.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
flush_reliable raised nothing for writes the ended session had forgotten; it
now raises ConnectionError with the reason. Server mode answered every
repeated Connect by queueing a fresh reliable Accept; a Connect from the peer
already accepted is now answered with the Accept still owed and queues
nothing, as the Rust hub does.

A session that refused a packet, or was disconnected, forgot its
unacknowledged writes, so flush_reliable returned success for writes the peer
never acknowledged. The transport now fails the flush with the reason and
reads such writes as Invalidated. Reset no longer reissues sequence numbers or
fragment ids: a late duplicate Connect in server mode reused sequences the
peer had seen. end_refused_session owns the reset-then-goodbye ordering for
the hub, the transport and the document server, which used to end a refusing
session silently.

AddJournal's Disposable.Create counted a refused dispose (from inside a journal
or another cache's hold) as done, leaving the journal registered forever. A
private registration now flips only after the removal succeeded. Held's catch
path dropped the hold's journal failures; it now throws an AggregateException
with the body's exception first. The store-composition contract states exactly
when the second getter read runs on a conditional commit. Adds the direct test
that a load is journaled.

Attaching a store with no file never calls Loaded, so it did not exercise the

A disposed R3 subscription ignores OnNext, so a no-op removal from the cache's
observer array cannot be seen by what a receiver gets; the test now checks the
cache stops holding the subscriber. An admission that changed nothing (a store
attached with no records) is not journaled.

The fragment-id-0 test is caught by the session-refusal branch, so a frame that

CultNetRudpPacketCodec.Decode did checked((int)length), so a datagram declaring
0x80000000 threw OverflowException, which no receive loop catches; the length
is now compared as a long and takes the ordinary malformed-packet drop.
Server mode claimed its endpoint on the first datagram of any type; only a
Connect claims it now. A session that refuses a packet has already recorded
its reliable sequence, so the socket transport and the listener end it: the
session forgets the peer (so the goodbye does not acknowledge the refused
frame), the peer gets a Disconnect, the listener drops the peer and raises
PeerDisconnected, and a server-mode transport forgets its endpoint.
CultNetRudpSession gains ResetPeerState, and the session and the listener
reject an InitialSequence of uint.MaxValue.

CultCache.AddJournal registers an ordered admission journal. It is called under
the gate right after Apply, once per admission that changed something, with the
admission's changes (dependents included) in Sequence order, before any
observer. A journal that throws joins the hold's failures: the admission stands,
the other journals run, the change is published and the writer hears of it
afterwards. Any hold entered while a journal runs throws. A hold now carries its
own changes and failures. Order stays data; no delivery thread or scheduler is
added.

Server mode claimed the endpoint on the first datagram of any type with the
right connection id, so an orphan Ack made a later real client a stranger. Only
a Connect claims it now. A session that refuses a packet has already recorded
its reliable sequence, so the transport ends it: the session forgets the peer
(so the goodbye does not acknowledge the refused frame), a Disconnect goes to
the peer, disconnect_reason is set, and a server-mode transport forgets its
endpoint. CultNetRudpSession gains reset_peer_state and rejects an
initial_sequence of 0xFFFFFFFF.

A session that refuses a packet has already recorded its reliable sequence, so
the socket transport now ends it: the session forgets the peer (so the goodbye
does not acknowledge the refused frame), sends a Disconnect, forgets the
endpoint in server mode, and emits disconnect and close. The operation service
did `void handleServerDatagram(...)`, so any rejection was an unhandled
rejection that ended Node; it now drops and counts the packet (packetsDropped),
ends a session that refuses a frame, and holds at most 64 sessions, dropping a
Connect from a new peer beyond that. CultNetRudpSession rejects an
initialSequence of 0xFFFFFFFF.

Judging the merge against the file re-runs Project for the records the commit
lands and for re-resolved variants, so "once per landing record" holds only for
the admission. Handing the plan's projections to Judging would not cover the
re-resolved dependents, so the contract now states the second read.

A hold whose body throws after it admitted changes still publishes them, and
Held now assigns its result up front so it compiles under Stryker Safe Mode
(CS0165 had dropped every mutant in it). Disposing a Watch subscription removes
the observer from the cache.

The Disconnect a refusing session sent carried the ack of the very frame it
refused, so the sender saw the frame acknowledged. The session forgets its
peer's sequences before building the goodbye, and a server-mode transport
forgets its endpoint so only a Connect can claim it again.
CultNetRudpSession::answer_repeated_connect is the one answer to a repeated
Connect for the hub and the document server: it records the sequence (the
document server's old accept_connect did, and a client that reconnects in one
session depends on it), applies acks, queues nothing, and returns the pending
Accept or an Ack.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The document server called accept_connect again for a Connect on an existing
key, queuing another reliable Accept each time: a resend storm, and the full
queue Err that the previous commit turned into a drop. The repeat now re-sends
the Accept still pending, or an Ack once acknowledged, as the hub does. A fresh
session's accept_connect cannot fail under validated options, so its error is
propagated again rather than counted as a drop.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
CultNetRudpSession::receive records a reliable sequence before reassembly, so
keeping the session after it refuses a frame made the sender's retransmit be
acknowledged and the frame silently lost. The hub and the socket transport now
end that peer's session, send it a Disconnect, and surface the end to the
caller (a Disconnected event, disconnect_reason()). The hub and socket
constructors reject initial_sequence u32::MAX and max_pending_reliable_packets
Some(0), so the accept_connect drops are unreachable. pending_accept_for_resend
becomes public for the document server.

Every public CultMath value type serializes: MessagePack in the default resolver
chain (byte-identical to Aetheria's and StreamPixels' copies across 653 values
and all 115 float fields of the real Aetheria.cc) and System.Text.Json converters
(STJ-parity number handling, math types as dictionary keys). CultVec2/3 and
CultRect are gone with bytes unchanged. The cultlib Unity package depends on
cultmath; the release gate refuses until CultMath 0.3.0 carries every type.
Three Soul passes.

Named literals now follow AllowReadingFromString and WriteAsString as
System.Text.Json's float does; quoted numbers refuse whitespace;
UnmappedMemberHandling.Disallow and AllowDuplicateProperties=false are honoured
and a repeated property replaces the whole value; dictionary keys read only the
canonical spelling. Components live in stack spans, property names are
pre-encoded, and there is no per-property closure, so a float3 read allocates
nothing (424 bytes before). Tests pin unknown nested values, de-DE and sv-SE
style cultures, and a distinct negative-zero key.

scripts/check-cultmath-types.cs reads the assembly with System.Reflection.Metadata

A malformed frame, a foreign connection id or a packet the session refuses
threw out of TryReceiveOnce. They are now counted in Stats.PacketsDropped and
the read reports progress. The client-side transport checks the connection
id before it claims the peer endpoint; the server listener drops refused
packets instead of throwing.
