Campaign P Slice P4 Opus review verdict: FIX-FIRST. RestrictionObjPrevalenceInspectionTests
(commit 3b5e0992) found 103,766 of 729,888 installed EnvCells (1,293 landblocks -
the whole housing estate) carry a baked RestrictionObj. The AP-71 gate's
unconditional fail-closed default (CanMoveInto unmodeled) would have locked
every apartment/cottage/villa interior for every player, including its own
owner - a live regression, not the "inert in dev content" the original
register row assumed.
Ports ACCWeenieObject::CanMoveInto (0x0058da40, pc:407982-408056) and
RestrictionDB::IsAllowedIn (0x005ae8f0, pc:444493-444516) verbatim into
ObjectInfo.CheckEntryRestrictions:
- owner_iid == 0 or == mover's own guid -> admit (open/owner)
- no RestrictionDB (retail _db == 0, i.e. never authored or not yet
received) -> admit
- present RestrictionDB -> IsAllowedIn: open-to-public flag, OR mover
shares the house's allegiance monarch, OR mover's own guid is a
guest-table member
- unresolved restriction object -> fails CLOSED, exactly retail's own
fallback when GetObjectA can't resolve it (pc:704-716)
Wire feed (Core.Net):
- CreateObject.cs: HouseOwner (WeenieHeaderFlag 0x02000000), HouseRestrictions
(0x04000000), and Monarch (0x40) PWD-tail fields were parsed-and-skipped;
now captured. Also fixes the HouseRestrictions PHashTable header
misconception: the wire is ONE packed u32 (low 24 bits = entry count),
not a separate count(u16)+numBuckets(u16) pair - verified against
Chorizite's RestrictionDB.generated.cs. The old skip's byte-count
happened to match for realistic guest-list sizes, but a future
numBuckets value >255 would have corrupted the parse; now correct
regardless.
- GameEvents.cs/GameEventWiring.cs: new House_UpdateRestrictions (0x0248)
parser + wiring - retail's live guest-list refresh, whole-unit replace.
No-ops if the house object hasn't arrived via CreateObject yet.
- ClientObject/WeenieData/ClientObjectTable: HouseOwnerId, MonarchId,
Restrictions (new HouseRestrictionRecord) fields + merge-preserving
Ingest + targeted UpdateHouseRestrictions.
Physics wiring:
- PhysicsEngine gains an Objects (ClientObjectTable?) property, mirroring
the existing DataCache pattern - acdream's GetObjectA equivalent, used
ONLY by the entry-restriction gate.
- RuntimeEntityObjectLifetime wires Physics.Engine.Objects = Objects in
all three constructors, right alongside the table's own construction -
the same canonical table every other subsystem borrows from, never a
second one. This is the production fix: without it the gate still fails
closed on every restricted cell (unresolvable object), so the wiring is
load-bearing, not cosmetic.
Register: AP-129 narrowed (not retired) to the genuine remaining residual -
House_UpdateRestrictions' Sequence byte isn't used for staleness/reordering
rejection (low-probability, self-correcting), and outdoor CLandCell
restriction (a separate DAT structure) remains unported and unaffected by
this fix.
Tests: 15 new/updated in Ap71EntryRestrictionGateTests.cs (resolved-unowned
admits, owner admits, present-list-excluded blocks, present-list-included
admits, open-to-public admits, shared-allegiance-monarch admits, unresolved
blocks via null and via an empty table, plus two new end-to-end
PhysicsEngine.Objects-wired scenarios); 2 new CreateObject parser tests +
2 new GameEventWiring tests for the wire feed.

Campaign N Slice N6, the final implementation slice.
ConnectResponse handshake retransmit:
- While the connection is unconfirmed, the Connect character-list pump
resends the IDENTICAL cleartext ConnectResponse (same sequence 1, same
cookie, the one encoded datagram - no new outbound state) on retail's
strict 0.333333333 s gate. Retail: ClientNet::ProcessConnection
@ 0x00545450, case cs_ConnectionRequestAcked @ 0x0054547B (the constant
load at 0x00545481; the mask-0x41 strictly-greater x87 test at
0x0054548C); ClientNet::SendConnectAck @ 0x005440F0 re-stamps
lastSentHandshake_ (0x00544102) and rebuilds the same cookie packet.
- Confirmation = the first checksum-valid post-negotiation packet whose
header lacks the ConnectRequest flag: retail's cs_ConnectionRequestAcked
-> cs_Connected edge (ClientNet::ProcessPacket @ 0x00545100, the 0x40000
exclusion at 0x0054514E, SetConnectionState(..., 5) at 0x00545160).
- The cadence rides the TransportClock (virtual-clock testable through
TransportClockSource); the Connect deadline stays wall-clock.
- ACE safety pinned against the N0 model: a duplicate while still
AuthConnectResponse re-routes idempotently through NetworkManager's
pre-route; after acceptance CheckState clause 2 drops it pre-CRC at
zero keystream cost.
- Pre-N6, one lost ConnectResponse was a hang to the Connect deadline;
the N5 decorator deliberately arms after this window, so nothing
covered it.
FragmentAssembler eviction (divergence register row AD-52):
- Partials evict 60 s after their last ACCEPTED fragment; the stamp
refreshes on every new fragment (retail's re-stamp rule,
ArrivedEphInfo::UpdateNetBlobID @ 0x0054AE00), so a merely-slow partial
can never age out - 60 s is a floor, not a tunable. Swept from
ReliableTransport.Sweep on retail's 5 s flush cadence
(Indicator::FlushTimedOutEphInfo @ 0x0054A3D0, the gate at 0x0054A3DC;
per-entry ArrivedEphInfo::fTimedOut @ 0x0054AE30). N4's RejectRetransmit
abandonment made an unrecoverable partial a REACHABLE permanent state;
the TTL reclaims it.
- A 64-entry completed-sequence ring drops late duplicate fragments of
already-completed messages instead of allocating a fresh partial that
can never complete (the completed-then-duplicate leak).
Fold-ins:
- N5 review LOW-5: NetProbeTests + LossyTransportDecoratorTests (the
static NetDiagnostics / Console.SetOut mutators) share one
DisableParallelization xunit collection so they never run alongside
classes constructing WorldSession.
- Campaign section 9: N6 ledger row recorded; N5 row verified carrying
4e290f00.
Gates: 757 Core.Net Release tests green (10 new); full solution Release
green (0 failures / 5 skips); connected lifecycle gate PASS; the
N5-strengthened connected loss gate PASS on its first live run (2%/seed 1:
dropped out=3 in=10, resends=1 nak-in=1 nak-out=5, cksum-fail=0
sanity-drop=0 uncached-nak=0).

Campaign N Slice N5 (docs/plans/2026-07-29-network-transport-campaign.md
section 8 rung 3): the permanent removal of the loopback blindness that let
#260 ship. Local ACE never drops a datagram, so every historical connected
gate was structurally incapable of exercising the N1-N4 recovery machinery;
from this slice on, tools/run-connected-loss-gate.ps1 runs the standard
lifecycle route through deterministic seeded loss and passes only on proven
non-zero recovery.
Observability:
- [net-tick] gains resend/s nak-out/s nak-in/s rej-in/s dup-drop/s parked/s
reclaim/s cache= nakset= - TransportStats window deltas mirroring the
acks/s cumulative-delta pattern, plus the two instantaneous depths (the
unbounded-like-retail sent-packet cache watchdog and the inbound NAK set).
TransportStats gains RejectsReceived (inbound RejectRetransmit packets).
Counters increment unconditionally; every string is behind
NetDiagnostics.ProbeNet (Code Structure Rule 5).
- WorldSession.Dispose emits one cumulative [net-final] totals line so the
loss gate asserts exact counters instead of reconstructing them from
rounded per-second rates.
- LinkStatusSnapshot.PacketLossPercentage is deliberately NOT wired: filed
#261 - retail's CLinkStatusAverages formula
(LinkStatusHolder::GetPacketLossPercentage @ 0x00411370) must be located
first; inventing a ratio is forbidden.
N4-review F3 fold-in:
- Fresh reliable sends stamp Header.Iteration = the session iteration
through the same shared retail header build already cited for Time (N3)
and the N4 control packets: FlowQueue::TransmitNewPackets @ 0x00547A60,
the stack build at 0x00547A84/0x00547AA8. The control-header rule now
holds across all three send shapes (fresh reliable, ack, NAK). ACE reads
neither Time nor Iteration inbound (campaign section 3) - wire-safe, and
resends keep the stamp verbatim per the N1 rebuild rule.
Loss injection (Transport/LossyTransportDecorator):
- IWorldSessionTransport wrapper with deterministic seeded per-direction
loss. Config via NetDiagnostics typed env properties read once:
ACDREAM_NET_DROP_PCT (0 = off = default), ACDREAM_NET_DROP_SEED (default
1), ACDREAM_NET_DROP_DIR (out|in|both, default both).
- Arming gate: NOTHING drops in either direction until the decorator has
FORWARDED the first ENCRYPTED outbound datagram - parse-free check on
length > 20 with EncryptedChecksum set in the LE flags word at bytes
4..8. The cleartext handshake always survives and the arming datagram is
never a casualty; handshake-loss testing belongs to N6's ConnectResponse
0.333 s retransmit.
- Structurally absent at 0%: WrapIfConfigured returns the raw transport -
WorldSession's default factory is the only production seam and a normal
run never constructs the decorator.
Root-cause fix the gate immediately exposed:
- The logoff-confirmation wait in Dispose processed inbound datagrams but
never pumped the transport, so a lost S2C logoff confirmation was
gap-detected but its healing NAK never went out. Retail's pump
(Client::UseTime @ 0x00411C40 -> PacketController::UseTime @ 0x005410D0)
runs until LogOffServer; the wait now sweeps per processed datagram,
making the logoff wait the third covered blocking pump (after Tick and
the handshake loops). A lost C2S logoff REQUEST remains unrecoverable by
ACE design (arrival-driven NAK; a quiet client is never NAKed - campaign
section 3 row 1), recorded in the gate header.
Gates:
- tools/run-connected-loss-gate.ps1 (-DropPct 2 -Seed 1): PASS vs local
ACE - the first automated observation of packet loss in project history.
Decorator ledger: dropped out=3 in=10 of forwarded out=183 in=496.
[net-final] resends=2 nak-in=2 nak-out=6 rej-in=0 acks-out=114
acks-in=119 dup-drop=0 sanity-drop=0 cksum-fail=0 parked=9 reclaimed=0
uncached-nak=0 cache=1 nakset=0. Every injected loss healed: both
ACE-driven C2S resend recovery (nak-in=2 -> resends=2) and client-driven
S2C NAK recovery (parked=9 -> nak-out=6) fired on a real connected
route, all six checkpoints validated, graceful logout confirmed, ACE
recorded the transport Disconnect.
- tools/run-connected-world-lifecycle-gate.ps1 (decorator absent): PASS -
zero behavior change on the no-loss baseline; the gate now defensively
clears the drop env vars.
- Core.Net Release: 747/747 (737 + 10 N5: decorator determinism/direction/
arming/structural-absence/env parsing, the 5% seeded WorldSession lossy
lifecycle with zero message loss both ways + ACE Headroom 256, the
[net-tick] field pins, the Iteration stamps).
- Full solution Release: 9,763 passed / 5 skipped / 0 failed.
Test-fixture note: FakeAceTransport gains AutoAdvanceOnBlockingReceive so
virtual time can move during the blocking Connect()/EnterWorld() pumps -
with the clock frozen there, a dropped handshake-window datagram could
never be NAK-healed (a fixture artifact, not a transport property).

Campaign N slice N4 completes the AckNakScheduler NAK branch and closes
the ACE cleartext-reject keystream hazard - the slice that makes S2C
loss actually RECOVER.
NAK emission (SharedNet::EnqueueNaks @ 0x00543BD0):
- One cleartext exact-flags RequestRetransmit per sweep behind the
STRICT 0.6 s gate on the ONE shared timestamp (the x87 0x41-mask test
at 0x00543C03 proceeds only on strictly-greater; the ack's gate stays
>=). Never an ack in a NAK sweep; a NAK delays the next ack by 2.0 s
and vice versa (landmine #7).
- Body = u32 count + ids ascending, capped at 114 (ReceiverData::GetNaks
@ 0x005490C0, cap 0x72; the m_cbData = 4*count+4 store at 0x00543C3E);
header Sequence borrowed from highestIDSent_ without incrementing;
cleartext or ACE ignores it (landmine #6, NetworkSession.cs:283-284) -
and a NAK never refreshes ACE's 60 s timeout.
- Control-header rule decided once for BOTH ack and NAK: Time = the
interval id, Iteration = the session iteration, matching retail's
shared header build (FlowQueue::TransmitNewPackets @ 0x00547A60, the
stack build at 0x00547A84). ACE reads neither field inbound.
- Gate ticks now round instead of truncate: 0.6 has no exact double
form, and truncation opened the strict gate exactly AT the boundary.
RejectRetransmit reclaim (divergence register AD-51, ACE adaptation):
- ACE's RejectRetransmit consumes a FRESH sequence, cleartext, with NO
keystream word, and is cached (ACE NetworkSession.cs:299-304,
:722-725, :743-748) - the one place ACE breaks retail's gap-walk
invariant that every missing id was word-bearing (retail cleartext
always borrows live sequences). Unhandled, the gap walk parks a word
for the reject's id and the inbound stream runs permanently one word
ahead - the N2 desync class reintroduced through the reject path.
- Fix: on a VALIDATED cleartext reject, InboundSequenceTracker removes
the mis-park, shifts every later-drawn parked word down one position
(per-word draw ordinals; ascending wrap-safe id <=> ascending draw
order), and pools the excess word, consumed lowest-draw-order-first
ahead of fresh ISAAC draws. Exact for any number of interleaved
rejects in ANY arrival order - a plain reclaim FIFO is not: a reject
arriving after a higher encrypted arrival crosses the parked chain,
and two out-of-order rejects pool their excess words out of draw
order (both orderings pinned by tests).
- Reject BODY ids keep N2's discard: word-bearing server-side,
consumed-in-place. The pool is provably empty against retail servers.
N3 advisories folded (all five): honest transitional-state wording (the
empty N3 NAK branch could silently disconnect a loopback session at
ACE's 60 s timeout, witness [net-tick] acks/s=0), the
ReceiverData::SharedInit @ 0x00548EF0 (from Init @ 0x00548FA0)
citation, the FlowQueue::Empty pump-order wording (TransmitNaks ->
TransmitAcks -> TransmitNewPackets with the interval increment LAST @
0x00548A9D; our clock-first Sweep is cosmetic vs ACE), the
Time/Iteration rule above, and the stale WorldSession budget-break
comment rewritten to the sweep reality.
Tests: 737 Core.Net green (14 new in NakEmissionTests + updated N3
pins): strict-gate boundary, shared timestamp both directions,
NAK-xor-ack exclusivity, full wire-shape + 114-cap pins, model-served
retransmission round trip, five tracker reclaim proofs, the 130 s
virtual prune -> fresh-sequence reject system test (victim abandoned,
later traffic decodes, pool drains to zero), 10 s long-loss survival
(NAKs on the gate cadence, zero acks, heal inside the window), and the
capstone soak: 2% seeded bidirectional loss x 10,000 messages -> zero
message loss both ways, ACE crypto headroom 256 at convergence, every
ledger drained (cache at the single watermark entry - retail's Flush
prunes STRICTLY below the ack). Full solution Release: 9,758 passed /
5 skipped. Connected world-lifecycle gate PASS
(logs/connected-world-gate-20260729-150238); canonical nine-stop soak
PASS (logs/connected-r6-soak-20260729-150856).

Campaign N slice N3. Retail never acks per packet: SharedNet::EnqueuePak
@ 0x00543B10 is the binary's only AckSequence (0x4000) construction site,
gated at >= 2.0 s on ReceiverData::timeStamp_ (@ +0x10), armed at
connection birth by ReceiverData::Init @ 0x00548EF0, and arbitrated
NAK-xor-ack per sweep by ClientNet::ProcessConnection @ 0x00545450
(m_SeqIDsWeNAKed non-empty -> EnqueueNaks, else EnqueuePak;
SharedNet::EnqueueNaks @ 0x00543BD0 shares the SAME timestamp -
campaign landmine #7).
- New Transport/AckNakScheduler: owns the one shared timestamp; a
non-empty NAK set suppresses the ack (N4 emits RequestRetransmit in
that branch; in N3 it emits nothing - a documented transitional state,
safe for exactly one slice on loopback), else ONE cleartext exact-flags
AckSequence carrying the tracker's HighestIdReceived, header sequence
borrowed from HighestIdSent without incrementing, 4-byte LE body.
Flags are an EQUALITY, never an OR (landmine #5 - ACE's dedup
exemption NetworkSession.cs:342-343 and watermark-skip :474-476 both
require the exact value).
- ReliableTransport.Sweep pump order per FlowQueue::Empty @ 0x00548A20:
interval clock, NAK/ack arbitration, pending resends, prune. The sweep
already runs in Tick and both handshake pump loops (landmine #8), so
cumulative acks flow during the character-list/enter-world floods at
ACE's own ~2 s cadence.
- WorldSession: the Phase 4.9 per-packet reflex ack in ProcessDatagram
and SendAck are DELETED; the [net-tick] acks/s probe now reads
Stats.AcksSent; new internal TransportClockSource seam drives the
2.0 s gate on virtual time in the conformance suite.
- N1 Fable-review advisory retired (Time-stamp fold-in): fresh reliable
sends now stamp Header.Time = the current interval id, matching retail
FlowQueue::TransmitNewPackets @ 0x00547A60 (header build at
0x00547A84); resends already re-stamped. ACE never reads inbound
Header.Time, so the wire stays compatible.
Tests: 723 Core.Net (7 new) - gate cadence + watermark-at-emission,
flags-equality pin + model acceptance at the reused sequence without a
watermark advance, NAK suppression and resume after the gap clears, a
50-packet CreateObject flood collapsing to ONE ack, the quiet-session
keepalive property across a 120 s virtual horizon (the reflex ack's
keepalive role, replaced and proven against ACE's 60 s TimeoutDeadline),
the Time fold-in, and a full FakeAceTransport lifecycle with zero
CRC/state/duplicate drops. Full solution Release: 9,744 passed /
5 skipped / 0 failed. Connected world-lifecycle gate PASS (capped +
uncapped-reconnect, graceful exits, 0 failures); canonical nine-stop
route PASS (0 failures).
Campaign section 9 N3 row updated (complete; SHA recorded at N4

Campaign N Slice N2 (docs/plans/2026-07-29-network-transport-campaign.md
S2.2) - the second fatal #260 fix: the inbound keystream now aligns to
SEQUENCE order instead of arrival order. One lost S2C datagram no longer
desyncs the inbound cipher permanently - the missing id's pre-drawn key
parks in the NAK set, later packets keep decoding, and the retransmission
decodes with the parked key.
New src/AcDream.Core.Net/Transport/InboundSequenceTracker.cs - retail's
ReceiverData inbound half, ported rule for rule:
- Sanity window: drop when seq is wrap-safe newer than
highestIDReceived_ + 0x7FFF (SharedNet::SeqIDSanityCheck @ 0x00543A20;
the boundary itself is accepted).
- Duplicate/late arrival (encrypted, at/below the watermark): NAK-set
hit -> decrypt with the PARKED pre-drawn key; miss -> silent drop at
ZERO keystream cost (SharedNet::ProcessNewSeqNum @ 0x00544690, the
AVL::Remove branch) - the dup-word-burn and double-dispatch bugs close
together.
- Gap walk (SharedNet::ProcessNewestSeqNum @ 0x00541930): one inbound
ISAAC word per missing id, drawn IN SEQUENCE ORDER BEFORE the arriving
packet's own key (landmine #4), parked beside the id
(ReceiverData::AddNakked @ 0x00549240, idempotent; id 0 skipped per
retail's `if (esi_1 != 0)`). Cleartext walks to seq+1 - the borrowed
id itself gets NAKed, so the real encrypted packet at that id can
still decode later.
- Verify-failure re-park: a sequenced encrypted checksum failure parks
the consumed key back beside its id so the retransmission decodes
(SharedNet::ProcessPacket @ 0x00544790 tail, AddNakked(seq, &key)).
- Inbound RejectRetransmit -> silent NAK-set abandonment; parked keys
discarded, alignment holds because the words were already drawn
(SharedNet::HandleEmptyAck @ 0x005448F0).
- NAK set = SortedDictionary<uint,uint> seq -> parked key; ascending
raw-uint enumeration matches retail's AVL walk for N4's <=114-id NAK
emission (ReceiverData::GetNaks @ 0x005490C0).
PacketCodec split (campaign S4, retail's own factoring - the key is an
optional in/out of ReceiverData::Decrypt): TryParseBorrowed is the pure
parse + checksum-summand computation with NO keystream access anywhere;
VerifyChecksum(header, headerHash, payloadHash, uint? key) compares the
additive cleartext form (null) or headerHash + (key ^ payloadHash).
TryDecodeBorrowed(datagram, IsaacRandom?) - the consume-before-compare
site that WAS the bug - is deleted; the owned TryDecode stays
(test-only). RejectRetransmit ids are now exposed on both decoders
(borrowed RejectRetransmitBytes/Count like the Request pair; owned
RejectRetransmits list); the bytes were always inside the hashed span,
so parse-hash coverage is unchanged.
WorldSession: ProcessDatagram head is now parse -> sequence-0 split
(cleartext seq-0 = handshake/control, verified additively and processed
as before; encrypted seq-0 dropped before any keystream access, like
retail's ProcessPacket) -> tracker.Admit -> VerifyChecksum with the
admission key -> failure re-park -> unchanged flag handling, N1
transport consumption, reflex ack, and fragment loop. The
RejectRetransmit flag routes to the tracker beside the N1 NAK/ack
consumption. The handshake Connect loop moved to parse +
cleartext-verify (no tracker exists before ISAAC seeding; the
ConnectRequest is cleartext seq 0). ReliableTransport now takes both
Isaacs and exposes Inbound; the session's _inboundIsaac field is
deleted. No production caller constructed the N1 ctor outside
WorldSession, so no compatibility shape was kept.
TransportStats gains InboundDupsDropped, InboundSanityDrops,
ChecksumFailures, KeysParked (unconditional, like the N1 counters).
Watermark init = 1 is an ACE adaptation, register row AD-50 (watermark
INIT only, not a mechanism change; AD-49 stays reserved for the campaign
S5 blob-layer deferral): retail zero-inits ReceiverData, but ACE never
emits S2C sequence 1 - PacketSequence starts unprimed at uint.MaxValue,
the cleartext ConnectRequest takes NextValue 0, and the first ENCRYPTED
flush re-primes CurrentValue to 1 so the first encrypted sequenced
packet is 2 (ACE NetworkSession.cs:716-717 resolving to
UIntSequence(startingValue: 1), Sequence/UIntSequence.cs:9-13,30-41).
A zero-init watermark would gap-walk the permanent id-1 hole: one
spurious NAK, the first pre-drawn word mis-assigned to id 1, and the
keystream off by one from the first encrypted packet onward. holtburger
seeds the same value (crates/holtburger-session/src/session/api.rs:30,
last_server_seq: 1), mirroring ACE's own C2S-side
lastReceivedPacketSequence = 1 (NetworkSession.cs:57). The N0 model's
dance is pinned by the clean-lifecycle conformance test: min encrypted
S2C sequence == 2, zero NAKs, zero spurious drops.
Tests (+14; Core.Net 702 -> 716): the decisive gap test (10,11,13,14 -
13 and 14 decode with fresh words while 12's key parks with
KeysParked=1/NakCount=1, the late 12 decodes with the parked key, 15
takes the next fresh word - impossible pre-N2), zero-cost duplicate
drop (shadow ISAAC position unchanged), re-park -> byte-identical
retransmission decode, the cleartext borrowed-id rule, cleartext at the
watermark (no NAK/key/watermark change), sanity boundary +0x7FFF
accepted / +0x8000 dropped wrap-safe, skip-id-0 across the 32-bit wrap
with ascending NAK enumeration, RejectRetransmit abandonment with
alignment held, warm zero-alloc Admit; plus four real-WorldSession
conformance runs against the N0 ACE double: clean lifecycle (zero NAKs
at every stage), S2C loss of one packet of a Count=2 fragment set
(later packets STILL decode - the N2 win; late byte-identical
redelivery completes the split message intact), duplicate delivery
dropped BEFORE dispatch, and the seq-0 tracker bypass.
N3/N4 handoff notes are recorded in the campaign S9 N2 row: the interim
per-packet reflex ack acks the arriving sequence even while a gap is
parked (ACE prunes the lost id from its S2C cache before N4 could NAK
it - message recovery needs N3's retail NAK-xor-ack sweep), and ACE's
RejectRetransmit consumes a fresh CLEARTEXT sequence with no keystream
word, an ACE-vs-retail wrinkle N4's design must resolve.

S2.1) - the direct #260 fix: every sent reliable packet is now cached and
re-emitted, header-rebuilt, when ACE NAKs a client-sequence gap. One lost
C2S datagram no longer voids every subsequent action for the session's
lifetime.
New src/AcDream.Core.Net/Transport/:
- TransportClock: injectable monotonic source + retail's 0.5 s interval
counter (ClientFlowQueue::IncrementLocalInterval @ 0x00547F10, tail
`intervalID_ += elapsed`; the same function's ~3 s TimeSync/Echo cadence
stays deferred per TS-58).
- SequenceMath: wrap-safe IsNewer/Max (TimeStampUtils::lhs_newer
@ 0x00543890, reduced to the signed-difference form).
- SentPacketStore: FIFO of ArrayPool-rented wire buffers; Add asserts
optionalLength == 0 (NetPacket::RemoveDisposableOptionalHeaders
@ 0x00549510 pinned as a no-op under standalone-control); FlushOlderThan
pops strictly-older wrap-safe (SentPacketStore::AddSentPacket
@ 0x0054AB00, Flush @ 0x0054ACD0).
- OutboundFlowQueue: owns the outbound ISAAC, highestIDSent (starts 1,
pre-increment, wrap 0xFFFFFFFF->1, never 0), the fragment sequence, the
store, the wrap-safe sorted dedup pending-resend list
(FlowQueue::EnqueueAcks @ 0x005488E0), and the flushNum_ ack watermark.
Cache commit happens AFTER a successful send
(FlowQueue::TransmitNewPackets @ 0x00547A60, commit site 0x00547C85).
NAK ids[0] folds into the watermark as retail's implicit cumulative ack
(RecipientData::ProcessNaks @ 0x00547010). A resend rebuilds ONLY the
20-byte header: flags Retransmission|EncryptedChecksum (|BlobFragments
with fragments), Time = current interval id, Sequence/Id/Iteration/
DataSize verbatim, checksum = fresh header hash + stored sealed checksum
(FlowQueue::TransmitAcks @ 0x005485B0, DequeueAck @ 0x005472F0). The
original ISAAC key rides inside the sealed value - no new keystream word
is ever drawn (CryptoSystem::EncryptData @ 0x0065FF40 non-null-key
path; landmines #1/#2). Resend only on explicit NAK (landmine #3).
- ReliableTransport: composition + Sweep() (interval clock, resends,
prune). The AckNakScheduler joins in N3/N4; ack behavior is untouched
this slice.
- TransportStats: unconditional counters (ResendsSent,
NakRequestsReceived, UncachedNakIds, AcksConsumed) + CacheDepth.
PacketCodec.FinalizeInPlace gains an overload returning (isaacKeyUsed,
sealedChecksum) where sealedChecksum is the pre-header-hash value -
payloadHash cleartext, isaacKey ^ payloadHash encrypted (retail
NetPacket::checksum_). The old signature forwards; encode bytes are
unchanged. Decode is untouched.
WorldSession integration is minimal: the transport is constructed at
ISAAC-seeding time (first reliable packet keeps sequence 2 / fragment 1,
byte-identical to pre-N1); SendGameMessage delegates (probe fseq/pseq now
read the transport); SendAck's borrowed sequence reads HighestIdSent
(identical value, behavior EXACTLY as-is this slice); ProcessDatagram
consumes RequestRetransmit + AckSequence BEFORE the unchanged reflex ack;
the sweep runs at the end of Tick() after the budget break AND inside
both blocking handshake pump loops (Connect step 4, EnterWorld
ServerReady - landmine #8), gated on _transportNegotiated; Dispose
returns the rented cache buffers.
Bookkeeping: TS-57 filed in the divergence register (uncached NAK ids
dropped silently + counted instead of retail's RejectRetransmit - ACE
no-ops the reject and the standalone unsequenced form would trip ACE's
watermark hole); TS-27 narrowed to the inbound direction in the same
commit; the stale WorldSession class-doc gap list corrected.
N0 fold-ins from the re-review: AceSessionModel.ProcessFragment split
into ACE's two literal branches (existing-buffer checks Complete,
NetworkSession.cs:495-507; new-buffer constructs + adds + TryAdds WITHOUT
checking Complete, :509-518), and the zero-count-fragment test now pins
the parked dead buffer (PartialFragmentBufferCount 0 -> 1). e3958610
recorded in the campaign ledger's N0 row.
Tests: 15 new in Transport/OutboundReliableTransportTests.cs - store
FIFO/strict/wrap-safe flush with rent/return balance via a counting
pool, interval-clock start/advance/wrap, resend header shape (flags
exactly 3 or 7, Time = interval, verbatim fields, checksum identity,
bit-identical body), resend-consumes-no-ISAAC-word, uncached-NAK
counting, ids[0] watermark fold + strict prune, wrap-safe ack max,
conformance resend verifying under AceCryptoModel with the ORIGINAL
parked key (Headroom 256, zero orphans, ordering restored), an
end-to-end FakeAceTransport lossy run (10 game actions, C2S #5 dropped,
all 10 dispatched in order, exactly one resend, session alive), and
zero-alloc steady-state SendGameMessage.

The first armed ACDREAM_PROBE_NET launch died at exit 4 one second into
the world: the [net-tick] line read _inboundQueue.Reader.Count, but the
queue is built with SingleReader=true and that channel implementation
throws NotSupportedException from Count. The net thread now increments
and the frame thread decrements a probe-owned Interlocked counter
instead; behavior with the probe off is untouched.

The two-agent investigation refuted #260's as-filed hypotheses: every
UseWithTarget was acked (the J5.2 use gate never latched), and the LOH
leak is bounded sawtooth churn - the real climb is ~2.25 GB of native/
GPU memory (WS 3,261 vs managed 1,015 MiB at wedge). The wedge evidence
also showed why it could hide: the live combat toggle routes through the
generation-gated runtime command seam, and every rejection exit in that
chain (Disposed / StaleGeneration / !IsInWorld at Validate, plus the
operations slot reading IsInWorld=false when unbound) is COMPLETELY
silent - no log, no event.
ACDREAM_PROBE_NET=1 (NetDiagnostics owner, PhysicsDiagnostics pattern)
now arms three probe families, all zero-cost when off:
- [net-out] per reliable send at the SendGameMessage chokepoint: opcode,
GameAction type+sequence, fragment/packet sequence, managed thread id
(two tids would prove the cross-thread ISAAC-desync hypothesis alone),
and state; [net-out-EX] via an exception FILTER that logs without
catching, so propagation is unchanged.
- [net-tick] 1 Hz cadence from WorldSession.Tick: inbound/s, queue
depth, budget breaks, worst inter-tick gap (frame-stall witness),
out/s, acks/s.
- [cmd-gate] every silent runtime-command rejection with expected-vs-
view generation, lifecycle, and IsInWorld, plus the combat toggle
result (whose Inactive exit reads a DIFFERENT IsInWorld source).
One walked-portal repro session with this probe distinguishes all
remaining #260 wedge hypotheses. ISSUES.md #260 rewritten to the
corrected two-root framing.

The lavapipe job did the thing it was built to do on its first attempt.
It accepted a Cpu device at API 1.4, created a device and read pixels
back, captured a real frame, and exited 4 when a feature was forced
unsupported. Three other things were red, and none of them were the
Vulkan backend.
The shader-freshness step aborted for two separate Linux faults in the
compiler tool. Disposing the Silk.NET API container unloads the native
module, and dlclose-ing libshaderc_shared.so leaves glslang's
process-level teardown running against unmapped code. Bisected with a
four-mode probe on Ubuntu 24.04: GetApi, CompilerInitialize and
CompilerRelease each exit 0, and adding only the container Dispose turns
the exit into SIGSEGV. That is the 134 CI reported. shaderc's own handles
are still released; the container is not, because the module's lifetime
is the process's and the process is one statement from returning.
Separately, a portable dotnet build leaves the native under
runtimes/linux-x64/native/ and makes reaching it Silk.NET's probing
problem, which it solved on a local Ubuntu 24.04 and did not solve on the
runner. The script now publishes the tool for the host RID, so the native
sits beside the assembly where AppContext.BaseDirectory finds it, and
checks for it by name so a regression says which file is missing rather
than which names failed.
With both fixed, the question section 5.5.20 left open has an answer:
Linux shaderc and Windows shaderc agree byte-for-byte at the pinned Silk
2.23.0. Eighteen of eighteen .spv identical, manifest identical. The byte
comparison stays a byte comparison.
The Windows leg of portable-headless was running sudo apt-get. That step
is older than this campaign - it is red in the 2026-07-27 main run too -
and it was misplaced rather than mis-conditioned. Nothing in that job
opens a display or links GL, and the graphical jobs that do call xvfb-run
take it from the runner image, so the step is deleted rather than
guarded. Every remaining step in the two-operating-system matrix is pwsh;
every bash step now lives in an ubuntu-only job.
The last failure was ours in a quieter way. WaitForCharacterLogOff-
Confirmation expressed its deadline only as a CancellationTokenSource,
whose timeout is published from a thread-pool timer callback, so on a
saturated pool the token stays unsignalled past the deadline while the
loop keeps draining items that are already queued. That is the case the
method exists to bound. Reproduced by pinning the suite to two CPUs on
Linux, which failed 2 of 6 where four CPUs and sixteen were clean, and
where CI failed 3 of 3. The drain now reads the deadline off the
monotonic clock as well; the token still bounds the asynchronous wait.
Ten of ten clean under the same pin. The test is untouched. Filed as
Release build green. App tests 4,152 / 3 skipped against the same 4,152 /
3 measured at base 32f9bcfa. Core.Net 600 / 600.

Write normal game-message and ACK packet framing directly into bounded stack spans, hash fragments without materialization, and send the populated slice to the socket. Preserve exact wire bytes and ISAAC failure ordering with differential and zero-allocation tests.
Decode headers, optional fields, fragments, and single-fragment messages directly over pooled datagrams. Copy only fragment state that crosses a datagram lifetime, preserve synchronous dispatch and ACK ordering, and lock the path to the owned decoder with differential and zero-allocation tests.
Replace timeout-polled in-world UDP receives with one cancellable caller-buffered socket operation. Transfer only right-sized pooled datagrams through the FIFO, return every ownership edge deterministically, and send caller spans without a transport copy while preserving handshake pacing and ACK order.
WorldSession.NetReceiveLoop wrapped its entire while loop in a single
try/catch, so ANY non-timeout SocketException permanently killed the
background receive thread: the catch block at the loop's end was empty
(misattributed the error to "socket closed during shutdown"), and the
finally called _inboundQueue.Writer.TryComplete(), which silently and
irrecoverably stopped all inbound processing for the rest of the
session — no log line, no recovery path, and LiveSessionHost.Reconnect
has zero production callers to notice.
The realistic trigger is a well-known Windows UdpClient quirk: an ICMP
"port unreachable" reply to an EARLIER Send (e.g. against a stale ACE
session that already tore down its socket) surfaces as a
WSAECONNRESET SocketException on this socket's NEXT, completely
unrelated Receive call. NetClient.Receive already swallows the
expected SocketError.TimedOut heartbeat case; anything else reaching
WorldSession was a real, transient, per-datagram error being treated
as session-fatal.
Three changes, root-cause not a band-aid:
- NetClient's constructor now disables SIO_UDP_CONNRESET reporting on
Windows, so a delayed ICMP error can't poison receives at all.
- NetReceiveLoop now catches SocketException PER ITERATION, logs it,
and continues polling instead of exiting. The existing clean-shutdown
paths (cancellation, ObjectDisposedException during Dispose) are
unchanged — only the non-timeout-socket-error case that used to kill
the loop is now recoverable.
- NetClient.Receive no longer calls the ReceiveTimeout setter (a
setsockopt syscall) on every single call — only when the requested
timeout differs from the last-applied value, cached in a new field.
This was an unrelated but adjacent finding (4x/sec syscall churn at
the 250ms heartbeat cadence) in the same audit.
No change to outbound wire behavior, ack cadence, heartbeat interval,
or datagram ordering — this is purely receive-loop resilience.
Tests: NetClientTests gained a SIO_UDP_CONNRESET construction smoke
test and two ReceiveTimeout-caching tests. A new
WorldSessionNetReceiveLoopResilienceTests drives the actual private
NetReceiveLoop method (via the existing internal
IWorldSessionTransport seam + reflection) with a scripted transport
that throws a non-timeout SocketException on the first call, proving
the loop survives it and keeps enqueueing subsequent datagrams — fully
deterministic, no real sockets. Full solution suite green: 3204/3206
Core, 3462/3465 App, 552/552 Core.Net (skips pre-existing).

Lands the codex-worktree D.2b stream plus the extraction the 2026-07-02
UI architecture review mandated before commit:
- ItemInteractionController: single owner of double-click use/equip/
container-open, targeted-use mode (health kits), drag-out drop;
toolbar shortcut drags don't drop the real item. ItemEquipRules for
multi-slot (coat) coverage via equip masks.
- Cursor phase: CursorFeedbackController (semantic priority chain:
drag > resize > window-move > target-mode > text) + RetailCursorCatalog
(enums 0x27/0x28/0x29, hotspot 14,14; ClientUISystem::UpdateCursorState
0x00564630) resolved through the portal EnumIDMap chain by
RetailCursorResolver; RetailCursorManager applies dat cursor art to the
OS cursor. Register row AP-72 covers the OS standard-cursor fallback.
- Character window goes live: CharacterSheetProvider owns sheet assembly,
XP-curve/raise-cost math and the raise flow — extracted out of
GameWindow per Code Structure Rule 1 instead of committing the ~430-line
feature body there. Optimistic XP/credit debits go through eventful
store APIs (new ClientObjectTable.UpdateInt64Property +
LocalPlayerState.DebitIntProperty/DebitInt64Property) instead of raw
property-dictionary writes; register row AP-73 covers the still-missing
raise ledger (#163).
- RetailWindowFrame: the shared nine-slice window mount recipe; the
character window uses it, remaining windows migrate via #164.
- Status-bar buttons toggle inventory/character windows; retail row-major
backpack ordering; WorldSession.SendUseWithTarget + raise/train sends.
GameWindow shrinks 14,214 -> 13,877 lines despite the new features; the
sheet/raise logic is unit-tested in CharacterSheetProviderTests instead
of trapped in the god object. Build green; full suite 3,286 tests pass.

Port retail's three-stamp inbound gate for 0xF74C UpdateMotion:
- MotionSequenceGate (Core/Physics): CPhysicsObj::is_newer (0x00451ad0)
wraparound u16 compare, verbatim per ACE PhysicsObj.is_newer (the BN
pseudo-C setcc returns are garbled; ACE + branch structure are the
oracle). Gates: INSTANCE_TS at dispatch (stale incarnation drops
before any stamp is touched), MOVEMENT_TS strictly-newer (stamped
BEFORE the server-control check, per CPhysics::SetObjectMovement
0x00509690), SERVER_CONTROLLED_MOVE_TS drop-when-stored-newer.
- Seed from CreateObject's PhysicsDesc timestamp block (index 1 =
ObjectMovement now parsed; ACE WorldObject_Networking.cs:411-420
order) — without seeding, entities whose movement sequence is past
0x8000 at spawn would drop every UM against a zero stamp.
Adopt-on-first / advance-only-after, so the #138 rehydrate replay of
retained spawns cannot regress live stamps.
- UpdateMotion + EntitySpawn now carry instance/movement/serverControl
sequences + isAutonomous (was parsed-past; isAutonomous feeds the
S2 funnel's last_move_was_autonomous). Gate wired at the top of
OnLiveMotionUpdated before any state mutation; [UM_STALE] diag under
ACDREAM_DUMP_MOTION / ACDREAM_REMOTE_VEL_DIAG; gate dropped with the
entity on DeleteObject.
Register: AD-32 added (adopt-newer-incarnation instead of retail's
QueueBlobForObject); TS-26 updated (UM side closed, UP side open).
Deviation map: docs/research/2026-07-02-inbound-motion-deviation-map.md.
19 new gate tests + parser coverage; full suite 3276 green.

Brings the 134 D.2b UI commits onto the physics/collision development line so
main can fast-forward. Today's #149 (BSP-less static collision) + #150 (open
doors fully passable) + the full collision/streaming/dense-town-FPS arc meet
the paperdoll/inventory work.
# Conflicts:
# docs/ISSUES.md
# docs/architecture/retail-divergence-register.md
PickupEvent (0xF74A) and DeleteObject (0xF747) are semantically distinct:
- 0xF747 = weenie DESTROYED → evict from ClientObjectTable (weenie_object_table)
- 0xF74A = object LEFT THE 3D WORLD VIEW (moved into a container) → remove
the 3D WorldEntity, but the weenie persists in ClientObjectTable
Before this fix, both paths fired EntityDeleted identically, causing
ObjectTableWiring to evict the weenie from ClientObjectTable. The follow-up
InventoryPutObjInContainer (0x0022) then tried MoveItem on an unknown guid
and no-op'd, so the unwielded item simply vanished.
Fix: add `bool FromPickup` (default false) to DeleteObject.Parsed. WorldSession
sets it true on the PickupEvent path and false on the DeleteObject path.
ObjectTableWiring.Wire's EntityDeleted handler skips table.Remove when
FromPickup is true, preserving the weenie for the container-move echo.
GameWindow.OnLiveEntityDeleted (3D entity removal) is untouched — it fires
for both pickups and destroys, as intended.
Divergence register: AP-65 added (data ghosts for other-player pickups until
teleport/relog clear; harmless — no UI queries ContainerId 0).
Tests: +5 (DeleteObject FromPickup parser regression; wiring retain/evict
semantics; Parsed default/explicit FromPickup). 343/343 pass.

After a teleport ACE floods a town's CreateObjects; WorldSession.Tick drained the
ENTIRE inbound queue every frame, each spawn hydrating mesh+textures under _datLock
on the render thread — monopolizing the update loop for ~a minute and starving the
streaming apply, so only the destination landblock loaded and neighbors trickled in
(visible at high render-FPS because update/render are separate Silk.NET callbacks).
Bound the per-frame drain to a ~4ms wall-clock budget once InWorld (handshake uses
the blocking PumpOnce path, never Tick). A time budget self-adapts to the highly
variable per-datagram cost; the tail stays queued (unbounded channel, FIFO) and
drains over the next few frames. Acks are queued per packet BEFORE the heavy handler
(WorldSession.cs:680), so deferring the tail only delays the tail's acks a few frames
— within ACE's tolerance (holtburger defers acks on a flush cadence; verified in
references/holtburger session/send.rs). Budget decision extracted as a pure testable
static (4 unit tests).
