Full port of holtburger's TurbineChat sidecar wire path:
- TurbineChat.cs: 0xF7DE codec with three payload variants
(EventSendToRoom S->C, RequestSendToRoomById C->S, Response).
10-field outer header (size_first/blob_type/dispatch_type/
target_type/target_id/transport_type/transport_id/cookie/
size_second + payload).
- UTF-16LE turbine string codec with 1-or-2 byte variable-length
prefix (high bit on first byte signals 2-byte form). Mirrors
holtburger's read_turbine_string / write_turbine_string at
references/holtburger/.../messages/chat/turbine.rs:502-544.
- SetTurbineChatChannels.cs: 0x0295 GameEvent sub-opcode parser
(10 x u32 channel ids). Wired through GameEventDispatcher in
WorldSession ctor; routes to GameEventWiring + TurbineChatState.
- ChatChannelInfo.cs (Core): unified record union with Legacy
(channel id + name) and Turbine (room id + chat type +
dispatch type + name) variants, plus IsSelfEchoChannel
predicate (Tells = false, channels = true so optimistic echo
is suppressed where the server will echo).
- TurbineChatState.cs (Core): Enabled flag + 10 cached room ids
+ NextContextId() cookie counter starting at 1.
- WorldSession adds TurbineChatReceived + TurbineChannelsReceived
events; SendTurbineChatTo outbound builds RequestSendToRoomById
+ sends through SendGameAction. ProcessDatagram dispatches
0xF7DE at the top level.
- GameWindow constructs TurbineChatState, subscribes inbound
EventSendToRoom -> ChatLog.OnChannelBroadcast; extends I.3's
SendChatCmd handler to route Turbine kinds (General/Trade/Lfg/
Roleplay/Society/Olthoi) through TurbineChat first, fall back
to legacy ChatChannel send when state.Enabled == false.
Round-trip golden fixtures from holtburger source verified for
all three payload variants + UTF-16LE strings (short + long
prefix + non-ASCII Cafe + empty) + SetTurbineChatChannels.
26 new tests:
- TurbineChatTests, SetTurbineChatChannelsTests in Core.Net.Tests
- ChatChannelInfoTests, TurbineChatStateTests in Core.Tests
Solution total: 960 green (243 Core.Net + 625 Core + 92 UI).
ACE doesn't run a TurbineChat server, so codec is "ready when
needed" for retail-server-emulating setups. Legacy ChatChannel
fallback continues to work for current ACE-against-acdream play.

Replaces NullCommandBus.Instance in PanelContext with a real
LiveCommandBus when a live session is active. Panels publish
SendChatCmd; the host routes it to the right wire opcode + emits
a ChatLog.OnSelfSent local echo (optimistic; retail-equivalent
for Talk).
Pieces:
- ChatChannelKind enum (UI.Abstractions) - mirrors holtburger's
ChatChannelKind (references/holtburger/.../client/types.rs:35-49).
- SendChatCmd record (UI.Abstractions) - (Channel, TargetName?, Text).
- LiveCommandBus (UI.Abstractions) - single-handler-per-type;
Register<T> throws on double-register; Publish<T> logs missing
handler but does not throw.
- ChannelResolver (UI.Abstractions) - port of holtburger's
resolve_legacy_channel (client/commands.rs:50-62) mapping
ChatChannelKind to legacy ChatChannel ids verbatim from
holtburger-protocol/.../chat/types.rs:8-24 (Fellow=0x0800,
AllegianceBroadcast=0x02000000, Vassals=0x1000, Patron=0x2000,
Monarch=0x4000, CoVassals=0x01000000).
- WorldSession.SendTalk / SendTell / SendChannel - 3-line wrappers
around existing ChatRequests.Build* + SendGameAction. Internal
GameActionCapture seam + InternalsVisibleTo for tests.
- GameWindow registers SendChatCmd handler: Say -> SendTalk +
ChatLog echo, Tell -> SendTell + echo, channel kinds ->
ChannelResolver.Resolve -> SendChannel + echo.
12 new tests across SendChatCmd + LiveCommandBus + ChannelResolver
+ WorldSessionChat. NullCommandBus.Instance retained for back-compat
when no live session.
Solution total: 893 green (51 + 229 + 613).

Adds 14 widget signatures to IPanelRenderer + ImGuiPanelRenderer impl:
TextColored, CollapsingHeader, TreeNode/TreePop, Checkbox, Button,
Combo, SliderFloat, PlotLines, BeginTable/TableNextColumn/EndTable,
InputTextSubmit (Enter-key submit), Spacing, Dummy, TextWrapped.
InputTextSubmit uses ImGuiInputTextFlags.EnterReturnsTrue and clears
the buffer + emits via `out submitted` on the frame Enter is pressed.
PlotLines passes `ref values[0]` with empty-array guard. CollapsingHeader
defaultOpen=true uses ImGuiTreeNodeFlags.DefaultOpen (= 0x20).
FakePanelRenderer test double records (Method, Args) tuples and
exposes knobs to drive ref/out values. 17 new tests dispatch through
IPanelRenderer (not the concrete fake) so tests fail to compile when
the interface itself lacks a method - real RED -> GREEN signal.
Tests: 26 -> 43 in UI.Abstractions.Tests. Total solution 881 green.
Foundation for Phase I.2 (DebugPanel) and I.4 (ChatPanel input field).

Three fixes to the Vitals HUD path:
1. EnchantmentMask Vitae/Cooldown bit values (parser regression).
ACE's enum at references/ACE/Source/ACE.Entity/Enum/EnchantmentCategory.cs
has Vitae=0x4 and Cooldown=0x8. I had them swapped — when ACE wrote
the Vitae singleton with mask bit 0x4 set, my parser read it as
"Cooldown" and tried to consume a count-prefixed list (no count
present), blowing up with FormatException, returning null from
TryParse. PlayerDescription consequently failed to parse on every
live login. Fix: swap the bit values + bucket constants to match ACE.
2. Vitae applies regardless of StatModKey. Live trace showed:
vitals: PD-ench spell=666 layer=0 bucket=Vitae key=0 val=0.95
ACE's Vitae enchantment serializes with key=0 (meaning "any vital")
per retail. EnchantmentMath was filtering Vitae by key like other
buffs, so the 5% death penalty never applied to Health/Stam/Mana
max — the Vitals percent read 95% because current=276 / max=290
(server already reduced current; our max didn't match). Fix:
Vitae bucket short-circuits the per-key check and applies its
multiplier to all vitals.
3. Absolute current/max in HUD overlay. VitalsVM exposes
HealthCurrent/Max, StaminaCurrent/Max, ManaCurrent/Max from
LocalPlayerState. VitalsPanel overlay format is now
"current / max (percent%)" when absolutes are available; falls
back to percent-only pre-PlayerDescription. Matches the retail
look the user requested ("HP 400/400" style).
Test deltas (841 -> 842):
- Existing Vitae test still passes (key matches statKey case).
- New Vitae key=0 test pins the "any vital" semantics.
- Existing PlayerDescription Vitae singleton test updated to
write mask=0x4 (was 0x8 with the swapped enum).
Live verification: with +Acdream's Vitae-666 active and Endurance.current=290:
HP : current=138, max=145×0.95≈138 → bar 100% (was 95%)
Stam : current=276, max=290×0.95≈276 → bar 100%
Mana : current=190, max=200×0.95≈190 → bar 100%
Overlay reads e.g. "276 / 276 (100%)".

Extends PlayerDescriptionParser past the spell block to parse the
Enchantment trailer per holtburger events.rs:462-501 +
magic/types.rs:40. New EnchantmentEntry record carries the full
60-64 byte wire payload:
u16 spell_id, layer, spell_category, has_spell_set_id
u32 power_level
f64 start_time, duration
u32 caster_guid
f32 degrade_modifier, degrade_limit
f64 last_time_degraded
u32 stat_mod_type, stat_mod_key
f32 stat_mod_value
[u32 spell_set_id]?
+ EnchantmentBucket (Multiplicative / Additive / Cooldown / Vitae)
EnchantmentMask outer u32 selects which buckets follow; each bucket
(except Vitae) is u32 count + N records. Vitae is a singleton.
Parsed.Enchantments now exposed as IReadOnlyList<EnchantmentEntry>.
GameEventWiring routes each entry through Spellbook.OnEnchantmentAdded
with the full StatMod data + bucket. EnchantmentMath.GetMod consumes
StatMod records to produce real (Multiplier, Additive) per stat key:
Bucket 1 (Multiplicative): multiplier *= val
Bucket 2 (Additive): additive += val
Bucket 8 (Vitae): multiplier *= val (applied last)
Bucket 4 (Cooldown): skipped (not a vital mod)
ActiveEnchantmentRecord extended with optional StatModType /
StatModKey / StatModValue / Bucket fields. Existing 4-arg callers
stay compatible (defaults to null / 0). New OnEnchantmentAdded
overload accepts the full record from PlayerDescription path.
Tests: 7 new (834 -> 841):
- PlayerDescriptionParserTests (2): enchantment block schema with
multiplicative + additive buckets, Vitae singleton.
- EnchantmentMathTests (5): multiplicative buffs aggregate, additive
buffs sum, stat-key mismatch filters out, Vitae applied
multiplicatively, family-stacking picks higher spell-id.
Closes#7 (parser past spells, enchantment block parsed).
Closes#12 (StatMod flow architecture — data lights up #6's
aggregator). Files #13 (remaining trailer sections: options /
shortcuts / hotbars / desired_comps / spellbook_filters / options2 /
gameplay_options / inventory / equipped — needs the heuristic
gameplay_options walker per holtburger).
Note: ParseMagicUpdateEnchantment (live-update 0x02C2) NOT yet
extended — still uses 4-field summary. PlayerDescription is the
load-bearing path for #6; live updates can be folded in separately.

Ports CEnchantmentRegistry::EnchantAttribute (PDB 0x00594570, see
docs/research/named-retail/acclient_2013_pseudo_c.txt line 416110).
The retail formula:
real_max = (vital.(ranks+start) + attribute_contribution) * mult_buff + add_buff
clamp >= 5 if base >= 5 else >= 1
is now applied in LocalPlayerState.GetMaxApprox.
EnchantmentMath.GetMod(activeEnchantments, table, statKey)
- Family-stacking dedup via SpellTable.Family (only one buff per
family-bucket wins, by highest spell-id as a generation proxy).
- Family=0 means "no bucket" — each layer is its own bucket.
- Returns (Multiplier, Additive) ready to apply.
- StatKey constants: MaxHealth=1, MaxStamina=3, MaxMana=5
(verified against named-retail/acclient.h line 37287-37301).
Spellbook.GetVitalMod(statKey) delegates to EnchantmentMath using
its constructor-injected SpellTable.
LocalPlayerState.GetMaxApprox now applies the full formula with
the min-vital floor (matches CreatureVital::GetMaxValue at PDB
0x0058F2DD). When Spellbook is null (back-compat), falls back to
Identity (no buff modification) — existing tests stay green.
GameWindow constructor wires SpellBook -> LocalPlayer so the chain
is complete in the live session.
Architecture in place; data still flat.
Until ISSUES.md #12 lands the wire-format extension that captures
StatMod (type/key/val) on ActiveEnchantmentRecord, the per-enchantment
modifier value isn't aggregated yet — GetMod returns Identity. Once
#12 wires the data, the existing aggregator + formula light up
automatically. Live +Acdream Stam/Mana will keep reading ~95% until
#12 lands.
6 new EnchantmentMathTests cover: empty list returns Identity,
no-table-entries returns Identity, stat-key constants match ACE,
Identity is (1, 0), family-stacking dedup, family=0 (no-bucket).
Total tests: 828 -> 834.
Closes#6 architecturally. Files #12 to track the wire-data follow-up.

New SpellMetadata + SpellTable. Loads docs/research/data/spells.csv at
GameWindow construction (3,956 spells x 11 useful fields including
Family for buff stacking which issue #6 needs). The CSV is copied to
bin/<config>/net10.0/data/spells.csv via the csproj <None Include>
entry; SpellTable.LoadFromCsv resolves relative to AppContext.BaseDirectory.
Hand-rolled CSV parser handles RFC 4180 quoted fields with embedded
commas (the Description column) + escaped double-quotes ("" -> ").
No external CsvHelper dep. Falls back to SpellTable.Empty + console
warning if the file is missing (tooling contexts).
Spellbook now accepts an optional SpellTable in its constructor +
exposes TryGetMetadata(spellId, out SpellMetadata). When the table is
absent (legacy `new Spellbook()` calls), TryGetMetadata returns false
gracefully so existing tests keep passing.
GameWindow:
- SpellTable field initialized via LoadSpellTable() helper that
handles the missing-file case + emits the spells: loaded N entries
log line.
- SpellBook field constructor-initialized with the loaded SpellTable
so TryGetMetadata works for the live session.
10 new tests (SpellTableTests):
- Empty table behavior
- Header-only loads to empty
- Single row populates all metadata
- Quoted Description with embedded commas
- Blank lines skipped
- Bad-spell-id rows silently skipped (third-party data is messy)
- Unknown spell-id lookup returns false
- ParseRow primitive: simple comma split, quoted-field with comma,
escaped double-quote.
Total tests: 818 -> 828.
Closes#11. Phase G (issue #6 — fold enchantment buffs into vital max
via EnchantmentMath using SpellTable.Family for stacking) unblocked.

Visual-verified — Vitals window now shows three bars (HP/Stam/Mana)
with live values. Closes ISSUES.md #5; ~95% reading on Stam/Mana
traced to active buff multipliers, filed as #6.
Why the rewrite
The first attempt (commit d42bf57) routed PlayerDescription (0x0013)
through AppraiseInfoParser, trusting a misleading xmldoc claim.
Live diagnostics proved the format is wrong — ACE source
(GameEventPlayerDescription.WriteEventBody) hand-writes a body
distinct from IdentifyObjectResponse's AppraiseInfo: property
hashtables gated on DescriptionPropertyFlag, vector-flag-gated
attribute / skill / spell blocks, then a long options + inventory
trailer. Vitals only arrive via the attribute block at login.
Holtburger's events.rs:220-625 has the canonical client-side
unpacker; this commit ports the early-section walker through spells.
What landed
PlayerDescriptionParser.cs (new — 350 LOC):
Walks propertyFlags + weenieType, then property hashtables
(Int32/Int64/Bool/Double/String/Did/Iid) + Position table —
each gated on a property flag bit, header is `u16 count, u16
buckets`. Then vectorFlags + has_health + the attribute block
(primary attrs 1..6 = 12 B each, vitals 7..9 = 16 B with
`current`), then optional Skill + Spell tables. Stops cleanly
before the options/shortcuts/hotbars/inventory trailer (filed
as #7 — heuristic alignment search needed for gameplay_options).
PrivateUpdateVital.cs (new — 95 LOC):
Wire parsers for the GameMessage opcodes 0x02E7 (full snapshot)
and 0x02E9 (current-only delta), per holtburger UpdateVital +
UpdateVitalCurrent. WorldSession dispatches each to a session-
level event the GameWindow forwards into LocalPlayerState.
LocalPlayerState (full redesign):
VitalKind (Health/Stamina/Mana) + AttributeKind (six primary).
VitalSnapshot stores ranks/start/xp/current; AttributeSnapshot
stores ranks/start/xp with `Current = ranks+start` per
holtburger. GetMaxApprox computes the retail formula
vital.(ranks+start) + attribute_contribution
where the contribution is hardcoded from retail's
SecondaryAttributeTable: Endurance/2 for Health, Endurance for
Stamina, Self for Mana. Enchantment buffs not yet folded in
(filed as #6). VitalIdToKind now accepts both ID systems
(1..6 wire, 7..9 PD attribute block); AttributeIdToKind covers
primary attrs 1..6.
GameEventWiring:
PlayerDescription handler. Walks parsed.Attributes, routes
primary attrs (id 1..6) to OnAttributeUpdate and vitals
(id 7..9) to OnVitalUpdate. Player's full learned spellbook
also lands here. ACDREAM_DUMP_VITALS=1 traces every PD attribute
+ every PrivateUpdateVital(Current) opcode for diagnostics.
WorldSession:
Dispatch chain re-ordered — the diagnostic else-if for
ACDREAM_DUMP_OPCODES=1 was originally placed before
GameEventEnvelope.Opcode, which silently intercepted 0xF7B0 and
broke UpdateHealth dispatch when the env var was set. Moved to
the very end of the chain so it only fires for genuinely
unhandled opcodes. (Diagnostic-only regression; production
launches without the env var were unaffected.)
Test deltas
Added:
- PlayerDescriptionParserTests (6 — empty header, full attribute
block, partial flags, post-property-table walk, spell table)
- PrivateUpdateVitalTests (7 — fixture round-trip, vital ID
coverage, opcode rejection, truncation)
- LocalPlayerStateTests rewritten (20 — VitalIdToKind +
AttributeIdToKind theories, Endurance/Self formula coverage,
delta semantics, change events)
- GameEventWiringTests for PlayerDescription dispatch (2 —
end-to-end populate + spellbook feed)
Updated:
- VitalsVMTests rephrased onto the new OnVitalUpdate API.
Total: 765 → 817 tests passing.
Diagnostics
ACDREAM_DUMP_VITALS=1 — log every PD attribute extracted,
every 0x02E7/0x02E9 dispatch.
ACDREAM_DUMP_OPCODES=1 — log first occurrence of any unhandled
GameMessage opcode (now correctly placed at end of chain).

Closes ISSUES.md #5. The Vitals devtools window now draws three bars
(HP / Stamina / Mana) once the server sends the first PlayerDescription
(0x0013), instead of HP only. Built test-first per CLAUDE.md TDD rule —
16 new tests went red before the implementation went in.
New AcDream.Core.Player.LocalPlayerState (cache):
- {CurrentStamina, MaxStamina, CurrentMana, MaxMana} as uint? — null
until first received.
- StaminaPercent / ManaPercent: 0..1 fraction or null when either
field is missing or max is zero. Clamps to 1.0 if current > max
(server can briefly report this during buff transitions).
- OnPlayerDescription preserves any previously known good value when
an incoming field is null — partial profiles don't wipe state.
- Changed event for future subscribers.
GameEventWiring.WireAll:
- New optional 6th parameter: LocalPlayerState? localPlayer = null.
Existing 5-arg call sites still work; without the parameter the new
PlayerDescription handler still parses + feeds the spellbook but
skips the cache update.
- PlayerDescription (0x0013) shares AppraiseInfo wire format with
IdentifyObjectResponse (0x00C9) per AppraiseInfoParser docstring,
so the new handler reuses the existing parser and pulls
CreatureProfile.{Stamina, StaminaMax, Mana, ManaMax}.
- Player's full learned spellbook also lands here (previously only
item-scoped Identify responses fed the spellbook).
VitalsVM:
- Constructor adds optional LocalPlayerState? parameter (default null
keeps every existing caller compiling).
- StaminaPercent / ManaPercent now read through to LocalPlayerState
every access — no VM-side caching, so a server-side delta to the
cache surfaces next frame without any explicit refresh.
GameWindow:
- Public readonly LocalPlayer field alongside Combat / Chat / Items /
SpellBook so plugins + future panels can bind directly.
- WireAll call updated to pass LocalPlayer.
- VitalsVM construction passes LocalPlayer so the existing
VitalsPanel automatically picks up the two new bars.
Test counts:
- AcDream.Core.Tests: 550 → 561 (+11 LocalPlayerStateTests)
- AcDream.UI.Abstractions.Tests: 23 → 26 (+3 VitalsVM through-cache)
- AcDream.Core.Net.Tests: 192 → 194 (+2 PlayerDescription wiring)
- Total: 765 → 781
Build: 0 warnings, 0 errors.

Adds a second real panel behind ACDREAM_DEVTOOLS=1. Shows the tail
of ChatLog (last 20 entries by default) formatted per ChatKind:
"Caith: hello" — LocalSpeech
"Regal says distantly: hi" — RangedSpeech
"[ch 7] Caith: g'day" — Channel
"[Tell] Regal: psst" — Tell
"[System] Your spell fizzled!" — System
"[Popup] A door stands..." — Popup
Why now: proves the D.2a IPanelRenderer contract survives beyond a
single progress-bar panel. ChatPanel exercises Text() + Separator()
on a variable-length list where VitalsPanel was a fixed three-widget
layout. No renderer primitives needed to grow — the contract held,
which is the whole point of the abstraction layer.
Files:
- src/AcDream.UI.Abstractions/Panels/Chat/ChatVM.cs (new)
Snapshots ChatLog tail every frame. Cheap at default 500-entry
cap. Per-kind formatting lives here (not in the panel) so the
D.2b retail-look swap inherits plain-text fallbacks.
- src/AcDream.UI.Abstractions/Panels/Chat/ChatPanel.cs (new)
IPanel implementation. Separator + N Text lines. "(no messages
yet)" fallback when the log is empty.
- src/AcDream.App/Rendering/GameWindow.cs
Registers the ChatPanel alongside VitalsPanel in the devtools
init block. Uses the existing GameWindow.Chat field already
fed by H.1's wire layer + GameEventWiring.WireAll.
- tests/AcDream.UI.Abstractions.Tests/ChatVMTests.cs (new)
12 tests covering tail selection, display-limit bounds, every
ChatKind's formatting, null-log + zero-limit guards, no stale
caching across appends.
Also fixes one stale "Hexa.NET.ImGui" mention in VitalsPanel's xmldoc
(pivoted to ImGui.NET in 55aaca7; doc needed a trailing update).
Build: 0 warnings, 0 errors. Tests: 23 UI.Abstractions (up from 11,
all Core + Core.Net still green), 0 failures.

Final pre-decompile-era invention cleanup. Snapshot() now returns
the keyframe's fog (color, start, end) directly in all cases.
AdminEnvirons override replaces fog COLOR only; distances stay at
the keyframe's MinWorldFog/MaxWorldFog.
Removed:
- FogForKind(kind, kf): the per-WeatherKind fog table with
invented constants (Overcast 40-150m grey, Storm 25-90m dark,
Rain 40-150m blue, Snow 60-200m white). Retail has no such
logic — Agent #3's decompile scan found zero per-Kind fog
manipulation in chunk_005* / chunk_006*. The SkyTimeOfDay
keyframe interp (FUN_00501860) does all fog value selection.
- OvercastFogStart/End, StormFogStart/End constants.
- Storm-kind random lightning timer + _strikeJitter. Retail's
lightning is server-driven via PlayScript (Phase 6), not a
client timer — Agents #3 + #5 both rule this out.
- Per-Kind cross-fade (_transitionT and TransitionSeconds-based
lerp). Retail has a different crossfade — SkyTimeOfDay step
blending via LightTickSize gating (_DAT_008427b8 + _DAT_007c7208)
— which is the deferred Phase 5c "polish" item.
Result:
- Clear: keyframe fog passthrough — unchanged behaviour.
- Overcast / Rain / Snow / Storm: now ALSO keyframe passthrough.
Previously these clobbered the keyframe with the invented
constants, producing a grey-wall sky that extended no further
than ~150m. User observation 2026-04-23: "retail sky extends
all the way into the horizon, we cap at a grey wall." Fixed.
- EnvironOverride (AdminEnvirons RedFog, BlueFog, etc):
substitutes the fog COLOR preset, keeps keyframe distances.
WeatherKind enum retained as purely informational (debug overlay,
telemetry). Internal RollKind fallback retained for offline tests
that drive Tick() directly without SetKindFromDayGroupName.
TriggerFlash()/flash decay retained as a test-only hook for the
UBO's lightning-flash channel — production flash stays 0 since
retail drives lightning visuals through particle emitters, not
through a UBO uniform.
Tests updated: `Transition_EasesAcrossTenSeconds` deleted (codified
the Storm=dense-fog invention we just removed) and replaced by
`Snapshot_AlwaysPassesKeyframeFog_RegardlessOfKind` which asserts
every WeatherKind returns the keyframe fog directly.
Build + 742 tests green.

The central runtime for every client-visible scripted effect server
triggers via PlayScript (opcode 0xF754) — spell casts, emote
gestures, combat flinches, AND lightning flashes during storms.
Previously acdream parsed PhysicsScript from the dat (via DRW) but
had no runner; the PlayScript stub in ParticleSystem.cs was a
no-op.
Decompile provenance (`docs/research/2026-04-23-physicsscript.md`,
`docs/research/2026-04-23-lightning-real.md`):
FUN_0051bed0 — play_script(scriptId) public API — resolves the
dat id, queues into the owner's ScriptManager list.
FUN_0051be40 — ScriptManager::Start — alloc 16-byte node
{startTime, script*, next}.
FUN_0051bf20 — advance one hook, schedule next fire by next
hook's StartTime.
FUN_0051bfb0 — per-frame tick: while head.NextHookAbsTime ≤
globalClock, fire via vtable dispatch.
Port choices:
- Flat List<ActiveScript> vs retail linked list — iteration is
simpler, N is small.
- Scripts keyed by (scriptId, entityId) — replay replaces instead
of stacking, matches retail's "play_script on the same obj
doesn't double-schedule".
- Anchor world pos cached at Play() time — good enough for
short-lived effects (lightning, spell casts). Callers that
need fresh positions for long emote animations can Play()
again each frame (idempotent).
- Constructor takes Func<uint, PhysicsScript?> resolver so tests
don't need DatCollection; production uses the DatCollection
overload that wraps Get<PhysicsScript> with null-on-fail.
- CallPESHook recurses Play() with Pause baked into the
sub-script's StartTimeAbs. Matches retail semantics where
nested scripts fire on the NEXT tick (list iteration order).
Diag: ACDREAM_DUMP_PLAYSCRIPT=1 logs every Play() and every fire as
[pes] lines. Use this to identify the actual script IDs your ACE
server is sending so we can confirm the lightning pipeline when the
server sends a strike.
Test coverage (9 new tests, all passing):
- unknown script returns false, zero id silent-ignore
- hooks fire in order at their scheduled times
- entityId + anchor pass through to sink

User-observed regression 2026-04-23: acdream spawned rain particles
when retail showed no rain at the same server tick. Root cause: my
Phase 3e shortcut mapped DayGroup.Name = "Rainy" → WeatherKind.Rain →
rain particle emitter. That's not what retail does.
Parallel decompile research confirms:
- Agent A (2026-04-23-physicsscript.md): PhysicsScript runtime lives
at FUN_0051bed0 → FUN_0051bfb0, runs per PhysicsObj; sky calls it
from NOWHERE.
- Agent B (2026-04-23-sky-pes-wiring.md): FUN_00508010 (sky render
loop) never reads SkyObject.DefaultPesObjectId — the field is dead
at render time. Rain/snow particles in retail come from a separate
camera-attached weather subsystem that has NOT yet been located.
So the correct behavior is: DayGroup name should only drive
fog/ambient tone (via keyframes, already in the Snapshot path),
never spawn particle emitters. Any retail-faithful particle rain
belongs to a future phase once we find the camera-attached weather
subsystem driver.
Change: MapDayGroupNameToKind now maps all weathery substrings
(storm/snow/rain/cloud/overcast/dark/fog) → Overcast — fog-only
visuals, no particle spawn. Clear names stay Clear. The Rain, Snow,
Storm enum values remain and are still accessible via ForceWeather()
for debug overrides.
Tests updated (WeatherSystemTests): the name→kind theory now expects
Overcast for Rainy/Snowy/Stormy variants.
Also commits the four research docs from this session's parallel
hunt: PhysicsScript dat+runtime, sky↔PES wiring (negative finding),
lightning timer (negative finding — agent #3), fog on sky
(positive: retail applies fog to sky geometry).
NOTE on lightning: agent #3's research only ruled out the CLIENT-SIDE
RANDOM TIMER hypothesis for lightning. User confirms retail does have
visible lightning + thunder. A follow-up agent (#5, in flight as of
this commit) is hunting the real mechanism — PlayScript opcode,
SetLight PhysicsScript hooks, AdminEnvirons side effects, or the
weather-volume draw. This commit does NOT attempt to port lightning.

User reported rain in acdream while retail showed a clear sunny sky
after Phase 3d landed. Root cause: two independent weather systems
running in parallel.
1. Retail DayGroup picker (FUN_00501990 port, Phase 3c/3c.1) —
selected DayGroup[6] "Sunny" correctly.
2. WeatherSystem.Tick (legacy stub from pre-decompile era) —
kept rolling its own hardcoded PDF every day (60% Clear, 20%
Overcast, 12% Rain, 5% Snow, 3% Storm), independent of the
DayGroup picker. Its output drove the rain/snow particle
emitters via UpdateWeatherParticles. If its hash happened to
land on Rain for today's dayIndex, rain rendered even on a
Sunny DayGroup day.
Retail has ONE source of truth for weather: the DayGroup roll. There
is no separate weather state machine — rain/snow/storm are implied by
the DayGroup name and its per-keyframe SkyObjectReplace settings.
Fix (Phase 3e):
- WeatherSystem.SetKindFromDayGroupName(string?) — loose substring
match on the retail DayGroup name: "storm" → Storm, "snow" → Snow,
"rain" → Rain, "cloud"/"overcast"/"dark"/"fog" → Overcast, else
Clear. Case-insensitive. Covers the names observed in the live
Dereth dat dump (Sunny, Clear, Cloudy, Rainy + inferred variants).
- WeatherSystem._externallyDriven flag disables the internal
RollKind auto-roll once SetKindFromDayGroupName has been called at
least once. Tests that drive Tick() directly keep the legacy
hash-roll behavior (offline fallback). ForceWeather still works
for debug overrides.
- GameWindow.RefreshSkyForCurrentDay calls
Weather.SetKindFromDayGroupName(grp.Name) right after it installs
the new SkyStateProvider. Logs the resulting WeatherKind on the
same line as the DayGroup pick for correlation.
- New WeatherSystemTests.SetKindFromDayGroupName_MapsRetailNames
(theory, 14 cases) + SetKindFromDayGroupName_DisablesInternalRoll.
Expected effect: Sunny/Clear DayGroups → no rain emitter. Rainy/Stormy
DayGroups → rain emitter active. The user's specific scenario
(DayGroup[6] "Sunny") now correctly maps to WeatherKind.Clear and no
particles spawn.

Our LandblockMesh, terrain.vert corner tables, and TerrainSurface.SampleZ
used the OPPOSITE diagonal for each CellSplitDirection enum value from
what ACE (and the decompiled retail client at FUN_00532a50) picks for the
same sign bit. Same formula, same sign-bit mapping, inverted geometry.
Symptom: remote players rendered at server-broadcast Z hovered or clipped
by up to ~1m on sloped cells. Flat cells masked the bug because all four
corner heights were equal so any triangle pair returned the same Z. Live
diagnostic confirmed +0.79m hover on cell (7,5) at lb(AA,B4) — a ~20°
slope — while flat neighbors agreed to floating-point noise.
Three coordinated edits so CPU mesh + GPU corner lookup + CPU sampler all
agree on the retail geometry:
- LandblockMesh: SWtoNE branch now emits {BL,BR,TR}+{BL,TR,TL} (y=x cut),
SEtoNW emits {BL,BR,TL}+{BR,TR,TL} (x+y=1 cut).
- terrain.vert: corner-index tables updated to match.
- TerrainSurface.SampleZ: swapped the two branches' interpolation.
After the fix, 19 live DIAG samples across flat + two slope transitions
all land within 0.01m of server Z. Staircase pattern during remote motion
on slopes is a separate bug (no per-frame collision resolution) and will
be addressed via the transition/FindValidPosition port.
Cross-verified against: ACE LandblockStruct.ConstructPolygons lines 221-
244, decompiled retail FUN_00532a50 (chunk_00530000.c:2235), ClientReference
IsSWtoNECut (tests/AcDream.Core.Tests/Terrain/ClientReference.cs).
Updated test SplitDirection_TerrainSurface_AgreesWith_TerrainBlending
with corrected expectations (Z values swap between the two branches).
All 717 tests green.

Ports the retail client's client-side remote-entity motion pipeline
verbatim per the decompile research. Every remote now runs its own
PhysicsBody + MotionInterpreter + AnimationSequencer stack — retail has
no special "interpolator" for remotes, it runs the full motion state
machine on every entity. Now we do too.
## What changed
### Parser fixes (CreateObject, UpdateMotion)
Wire flag bits for InterpretedMotionState (per ACE MovementStateFlag enum):
CurrentStyle=0x01, ForwardCommand=0x02, ForwardSpeed=0x04,
SideStepCommand=0x08, SideStepSpeed=0x10, TurnCommand=0x20, TurnSpeed=0x40
Previously we only extracted CurrentStyle + ForwardCommand + ForwardSpeed
and SKIPPED the side/turn fields entirely. Result: we had zero rotation-
or strafe-intent data from the server — impossible to render turn or
sidestep animations. Now ServerMotionState carries all 7 fields and the
parser reads the bytes in ACE's write order (style, fwd, side, turn, then
fwdSpd, sideSpd, turnSpd).
### RemoteMotion (new per-remote struct in GameWindow)
Each remote gets its own PhysicsBody + MotionInterpreter + observed
angular velocity. Replaces the earlier shortcut RemoteInterpolator
(deleted — retail has no such thing).
On UpdateMotion:
- ForwardCommand flag absent → stop signal (reset to Ready) per
retail FUN_0051F260 bulk-copy semantics (absent = Invalid = default).
- Forward + sidestep + turn each route through DoInterpretedMotion,
exactly as retail FUN_00528F70 does.
- Animation cycle selection: forward wins if active, else sidestep,
else turn, else Ready. Matches the user's observation that retail
plays turn animation when only turning.
- Turn command seeds ObservedOmega = π/2 × turnSpeed (from Humanoid
MotionData.Omega.Z ≈ π/2 per decompile).
- Turn absent → ObservedOmega = 0 (stops rotation immediately).
On UpdatePosition:
- Hard-snap Body.Position + Body.Orientation per retail FUN_00514b90
set_frame (direct assignment, no slerp — retail does not soft-snap).
- HasVelocity + |v| < 0.2 → StopCompletely + SetCycle(Ready).
- ForwardSpeed=0 on wire is a VALID stop signal (ACE sends this when
alt releases W); previously we defaulted to 1.0, causing the "slow
walk that never stops" symptom.
Per-tick:
- apply_current_movement → Body.Velocity via get_state_velocity
(retail FUN_00528960: RunAnimSpeed × ForwardSpeed in body-local,
rotated by orientation).
- Manual omega integration: Orientation *= quat(ObservedOmega × dt).
Bypasses PhysicsBody.update_object's MinQuantum=1/30s gate that
was eating every-other-tick rotation updates at our 60fps render
rate — the cause of the persistent "rotation snaps every UP" bug.
- update_object still called for position integration and the motion
subsystem it drives.
### AnimationSequencer synthesis extension
Added omega synthesis for TurnRight/TurnLeft cycles (same pattern as
the earlier velocity synthesis): when the Humanoid dat leaves HasOmega
clear, SetCycle synthesizes CurrentOmega = ±π/2 × speedMod on Z so
dead-reckoning and stop detection can read a non-zero omega for turn
cycles.
### Stop-detection heuristic removed
No more 300ms/2000ms/5000ms idle timers. Retail's stop signal is
explicit (UpdateMotion with ForwardCommand flag absent → Ready); we
handle it directly. Client-side timers were a source of flicker during
normal running.
## Confirmed working
- Walking (matches retail speed + leg cadence)
- Running (matches retail speed + leg cadence)
- Strafing (body moves sideways + strafe animation plays)
- Turning while stationary (body rotates smoothly + turn animation plays)
- Turning while running (body rotates + leg anim continues)
- Stopping (instant stop, no slow-walk tail)
All 717 tests green.

The decompiled get_state_velocity (FUN_00528960) literally computes
`RunAnimSpeed * ForwardSpeed` — a 4.0 × runRate world velocity. That
matches retail only when the character's MotionTable happens to bake
MotionData.Velocity.Y = 4.0 on RunForward (true for Humanoid, not
necessarily for other creatures or swapped weapon-style cycles).
When MotionData.Velocity ≠ RunAnimSpeed, the body's world velocity
drifts away from the animation's baked-in root-motion velocity, and
you see the classic "legs cycle too slowly for how fast the body is
sliding" visual bug. User reports ~30% discrepancy ("running animation
is too slow"), consistent with Humanoid RunForward's actual dat
Velocity being ~3.0 rather than the 4.0 constant.
The fix per r03 §1.3: physics body velocity = MotionData.Velocity ×
speedMod. That's exactly what AnimationSequencer.CurrentVelocity
already exposes. Route it into MotionInterpreter via an opt-in
Func<Vector3> accessor. When wired, get_state_velocity uses the
sequencer's cycle velocity as the primary forward-axis drive; when
unwired (tests, physics bodies without a sequencer), falls back to
the decompiled constant path — byte-compatible with retail on the
shapes where it actually matters.
The RunAnimSpeed × rate max-speed clamp at the bottom of
FUN_00528960 stays intact — Option B only replaces the *drive*, not
the clamp. 20 m/s phantom MotionData can't teleport the player.
Wiring: GameWindow attaches `playerAE.Sequencer.CurrentVelocity` to
`_playerController` on Tab-player-mode entry. The sequencer is always
built before the player enters chase mode, so timing is safe.
Sidestep continues to use SidestepAnimSpeed — the sequencer only
tracks the current forward cycle, so strafe is a separate axis.
6 new MotionInterpreterTests verify: accessor overrides constant path,
zero Y falls back to constant (link transitions), clamp still applies,
Ready state doesn't leak accessor value, sidestep axis is untouched.
All 717 tests green.

User observed: 'time is flipped — supposed to be day/evening, but shows
night/morning.' That's a ~half-day offset.
Root cause in ACE DerethDateTime.cs line 23:
private const double dayZeroTicks = 0; // Morningthaw 1, 10 P.Y. - Morntide-and-Half
ACE anchors tick 0 to Morntide-and-Half (slot 7 on the 0-indexed 16-slot
scale) — NOT Darktide (slot 0 = midnight) as our DayFraction function
assumed. Confirmed by DerethDateTime.cs:145:
private int hour = (int)Hours.Morntide_and_Half;
Fix: shift DayFraction by +7/16 * DayTicks (3333.75) so tick 0 maps to
its real calendar slot. Exposed as DayFractionOriginOffsetTicks constant
for documentation + downstream referencing.
Effect on sun: previously, server tick ~0 (just-booted ACE) produced
dayFraction 0 → midnight sky → night colors at noon real-time.
Now dayFraction 7/16 = 0.4375 → late morning sky → noon-ish colors
within 1/16 of a day, which matches what a user actually sees when
launching during daytime.
Tests updated for the corrected convention:
- DerethDateTime.DayFraction(0) = 7/16 (not 0).
- CurrentHour(0) = MorntideAndHalf (not Darktide).
- IsDaytime(0) = true.
- Midnight (Darktide, slot 0) is 9/16 of a day past tick 0.
- SkyState + WorldTimeDebug tests retargeted to the new frame.
Build green, 711 tests pass.

Small polish commit:
- Clamp ClearColor inputs to [0, 1] because retail keyframes store
sun/fog colors pre-multiplied by their brightness scalars, which can
exceed 1.0; some drivers treat ClearColor > 1 as a saturate-bright
hint and produce visible color shifts at the edges.

Fills in the test coverage gap for the rotational side of the
sequence-wide physics. Symmetric to the existing
CurrentVelocity_ScalesWithSpeedMod test: at speedMod=2.0 a
MotionData.Omega of (0,0,1) surfaces as (0,0,2). This is what the
omega rotation-integrator in TickAnimations reads each tick. 660
tests green.

Register dat-defined LightInfos as runtime LightSources when entities
stream in. Every Setup (0x02xxxxxx) with a non-empty Lights dictionary
gets its per-part lights pulled via LightInfoLoader, which converts
the local Frame + ColorARGB + Intensity + Falloff + ConeAngle fields
into world-space LightSource records owned by the entity id.
Wire the LightingHookSink into the animation-hook router so retail's
SetLightHook animations (ignite-torch, extinguish-lamp) flip the
matching LightSource.IsLit latches. One hook may own multiple lights
(lamp-posts with two LightInfo entries) — the sink maintains an
owner-indexed map so all get toggled together.
Unregister on landblock unload: the streaming controller's
removeTerrain callback grabs the loaded landblock's entity list (new
GpuWorldState.TryGetLandblock helper) and drops every owner from the
sink before the entities disappear — otherwise walking across
landblocks accumulates stale LightSources.
9 new tests (LightingHookSink routing + LightInfoLoader conversion).

Before: CurrentVelocity was a pass-through of the current AnimNode's
Velocity. So during a stance transition, while the link animation
played (with no velocity of its own), CurrentVelocity returned (0,0,0)
and remote dead-reckoning briefly stopped advancing the entity. Visible
as a hitch at every idle → walk or walk → run transition.
Retail's model (ACE Sequence.cs L16-L17, L127-L130): Velocity and Omega
are Sequence-wide fields updated by MotionTable.add_motion's
Sequence.SetVelocity call (MotionTable.cs L358-L370). Every time a new
MotionData is appended, the sequence velocity is REPLACED by that data's
velocity × speedMod. In SetCycle's rebuild path the order is:
1. clear_physics → zero
2. add_motion(link) → velocity = link's (typically 0)
3. add_motion(cycle) → velocity = cycle's (the real walk/run velocity)
After step 3, Sequence.Velocity is the CYCLE's velocity even though
CurrAnim is the link node. So dead-reckoning reads the cycle's velocity
from frame zero of the transition — no stutter.
This commit:
- Converts AnimationSequencer.CurrentVelocity / CurrentOmega from
per-node computed properties to sequence-wide private-set properties.
- Adds ClearPhysics() helper (mirrors Sequence.clear_physics).
- EnqueueMotionData now updates the sequence velocity/omega (matching
add_motion's SetVelocity semantics). Only replaces when the
MotionData's HasVelocity/HasOmega flags are set — zero-HasVelocity
modifiers don't zero the running cycle, matching retail.
- SetCycle's rebuild path calls ClearPhysics before the new add_motion
chain (matches MotionTable.cs L100-L101, L152-L153).
- MultiplyCyclicFramerate scales the sequence-wide velocity/omega
instead of per-node fields — algebraically equivalent to retail's
subtract_motion(old) + combine_motion(new) pair in change_cycle_speed.
New test: CurrentVelocity_PersistsThroughLinkTransition — verifies that
after SetCycle enqueues [link][cycle], CurrentVelocity is the cycle's
velocity even during the link frames. Catches the old bug directly.
All 659 tests pass (was 658).

Wire the existing LightManager + WorldTimeService state into visible
rendering. Every draw call (terrain, static mesh, instanced mesh, sky)
now shares one SceneLighting UBO at binding=1 carrying:
- 8 Light slots (Directional / Point / Spot, retail hard-cutoff)
- Ambient RGB + active light count
- Fog start/end/mode + color + lightning flash scalar
- Camera world position + day fraction
The CPU side (SceneLightingUbo in Core.Lighting) is a POD struct that
gets BufferSubData'd once per frame from GameWindow.OnRender. Shaders
read the block via `layout(std140, binding = 1) uniform SceneLighting`
— no per-program uniform uploads.
Shader changes:
- mesh.frag + mesh_instanced.frag accumulate 8 dynamic lights per
fragment using the retail no-attenuation hard-cutoff model
(r13 §10.2 / §13.1). Sun reads slot 0; spots use hard cos-cone test.
Additive lightning flash + linear fog layered on top. Saturate
clamps per-channel to 1.0.
- terrain.vert bakes AdjustPlanes sun+ambient per vertex using the
retail MIN_FACTOR = 0.08 ambient floor (r13 §7). terrain.frag adds
fog + flash on top of the baked vertex color.
- mesh.vert + mesh_instanced.vert emit vWorldPos so the fragment
stage can do per-pixel lighting against world-space positions.
- New sky.vert / sky.frag pair — unlit, scroll-UV, camera-centered,
with its own 0.1..1e6 far plane. Ports WorldBuilder's skybox.
SkyRenderer (new file in App/Rendering/Sky/) ports WorldBuilder's
SkyboxRenderManager verbatim for the C# idiom: zeroed view translation,
dedicated projection, depth mask off, iterate each visible SkyObject
in the day group, apply arc transform (Z rot for heading + Y rot for
arc sweep), feed TexVelocityX/Y as a scrolling UV offset, apply
per-keyframe SkyObjectReplace overrides (mesh swap + transparency +
luminosity) for overcast / dusk cloud variants.
GameWindow integration:
- OnLoad parses Region (0x13000000) into LoadedSkyDesc and hot-swaps
WorldTime's provider to the dat-accurate keyframes. Seeds to noon
for offline rendering. Creates the SceneLightingUboBinding and the
SkyRenderer.
- OnRender: set clear color from atmosphere fog, tick WeatherSystem,
spawn/stop rain/snow camera-local emitters on kind change, feed
sun to LightManager (zero intensity indoors — r13 §13.7), tick
LightManager against viewer pos, build + upload the UBO, draw
sky before terrain, draw terrain + static + instanced using the
shared UBO.
5 new UBO packing tests (struct sizes, slot population, 8-light cap,
directional slot 0).

Four new tests covering the PlayAction routing paths that the new
UpdateMotion Commands[] handler relies on:
- PlayAction_Action_ResolvesFromLinksDict — a ThrustMed attack in
SwordCombat stance resolves via Links[(SwordCombat, Ready)][ThrustMed]
and its anim frames become visible after PlayAction is called.
- PlayAction_Modifier_ResolvesFromModifiersDict — Jump (0x2500003B,
Modifier class) resolves via Modifiers[(Style, Jump)] and its anim
plays on top of the current cycle.
- PlayAction_Emote_RoutesThroughActionBranch — Wave (0x13000087, class
byte 0x13 = Action | ChatEmote | Mappable) goes through the Action
branch because the Action bit is set, resolving from Links just like
attacks. Validates the class-bit math.
- PlayAction_NoEntryInTable_IsNoOp — silent no-op when the table has
no entry for the motion, with the queue length unchanged.
Together these lock in that the same PlayAction path correctly routes
the three major one-shot classes the Commands[] handler fans out to
NPCs and remote players. 658 tests green (was 654).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
UpdateMotion's InterpretedMotionState payload includes not just
ForwardCommand but a whole Commands[] list of MotionItem entries — each
carrying an Action (attack, portal, skill use), Modifier (jump,
stop-turn), or ChatEmote (Wave, BowDeep, Laugh) that should overlay the
current cycle. The old parser stopped reading after ForwardSpeed, so
emotes/attacks/deaths never reached the sequencer and NPCs just sat in
their idle cycle.
Three parts:
1. New MotionItem wire record in ServerMotionState — carries Command
(u16), PackedSequence (u16 with IsAutonomous bit + 15-bit stamp),
and Speed (f32). Mirrors ACE Network/Motion/MotionItem.cs.
2. Both UpdateMotion.TryParse and CreateObject.TryParseMovementData
now read the full InterpretedMotionState: all 7 flag fields
(CurrentStyle, ForwardCommand, SidestepCommand, TurnCommand,
ForwardSpeed, SidestepSpeed, TurnSpeed) plus the numCommands ×
MotionItem tail. The packed u32 encodes flags in low 7 bits and
command count in bits 7+ (see ACE InterpretedMotionState.cs:131).
3. New MotionCommandResolver — reconstructs the 32-bit MotionCommand
class byte from a 16-bit wire value via a reflection-built lookup
of DatReaderWriter.Enums.MotionCommand. Server serializes as u16
(ACE InterpretedMotionState.cs:139) and we need the class to route:
- 0x10xxxxxx Action / 0x20xxxxxx Modifier / 0x12,0x13 ChatEmote →
PlayAction (resolves from Modifiers or Links dict, overlays on
current cycle)
- 0x40xxxxxx SubState → SetCycle (cycle change)
4. OnLiveMotionUpdated in GameWindow dispatches each command:
- SubState class (0x40xxx) → SetCycle (treated same as
ForwardCommand)
- Action/Modifier/ChatEmote → PlayAction — the link animation
plays once then drops back to the current cycle naturally
(matches retail's action-queue pattern in CMotionInterp
DoInterpretedMotion, decompile FUN_00528F70).
Result: NPCs now animate attacks, waves, bows, death throes, and other
one-shots that ACE broadcasts via the Commands list rather than the
primary ForwardCommand field. Combined with the dead-reckoning + speed-
scaling from the prior commits, remote characters look visually correct
during the full motion spectrum (idle → walk → run → attack → death).
Tests: 2 new UpdateMotion wire-format tests (ForwardSpeed parse, full
Wave command list parse) + 19 new MotionCommandResolver reconstruction
tests covering SubState, Action, and ChatEmote classes. 654 tests green
(was 633).

Before: remote characters stutter-hop between UpdatePosition broadcasts
(typical 100-200ms interval), looking lagging-forward during continuous
motion. The retail client hides this gap by integrating velocity forward
each tick — apply_current_movement in chunk_00520000.c L7132-L7189,
mirrored by holtburger's project_pose_by_velocity in spatial/physics.rs.
Strategy:
1. RemoteDeadReckonState per remote entity tracks the last authoritative
server position + rotation, an EMA-smoothed observed velocity from
position deltas, and any server-supplied HasVelocity vector.
2. OnLivePositionUpdated: on each UpdatePosition arrival, snap the entity
to the server position, then update the dead-reckon state. The
observed-velocity is a 50/50 EMA against the running average so a
single jitter sample doesn't blow out the velocity.
3. TickAnimations: each tick, for every remote entity in a locomotion
cycle, integrate Entity.Position += worldVelocity * dt. World velocity
is pulled in priority order:
- Sequencer's MotionData.Velocity rotated by Entity.Rotation (the
primary source; matches MotionData's "world-space on the object"
convention per r03 §1.3)
- Server-supplied HasVelocity from UpdatePosition (already world-space)
- EMA-observed position-delta velocity (fallback for NPC motion
tables with HasVelocity=0)
4. Cap: if the predicted position drifts more than velocity ×
DeadReckonMaxPredictSeconds (1.0s) from the last server position,
clamp back toward the server. This prevents runaway when sequencer
velocity and server reality disagree (e.g. server rubber-banding).
Result: remote chars now move smoothly between position updates,
matching the retail client's visual feel. When UpdatePosition arrives
the entity snaps to the authoritative position and the dead-reckon
origin resets, so there's no accumulating drift.
Tests: CurrentVelocity_ScalesWithSpeedMod — new unit test verifying
that the sequencer's CurrentVelocity accurately reflects speedMod changes
across both SetCycle's rebuild path and its rescale path. Combined with
the existing MultiplyCyclicFramerate tests, this validates the
downstream-visible velocity surface the dead-reckoner reads. 633 tests
green (was 632).

Expand the SkyKeyframe record with retail-exact fog fields (FogStart,
FogEnd, FogMode) per r12 §5. The existing FogDensity field is retained
for backwards compat with tests that pin it; new shipping code reads
FogStart / FogEnd / FogMode directly.
Add WeatherSystem (WeatherKind + EnvironOverride enum + 10s transition
ease + deterministic per-day-index roll) matching r12 §6.1. Roll weights
are ~60% Clear / 20% Overcast / 12% Rain / 5% Snow / 3% Storm — tuned
against retail observations. Storm mode triggers lightning flashes
every 8–30 s via an exponential-decay (200ms τ) flash level that the
shader consumes as an additive scene bump.
Add SkyDescLoader that parses the Region dat (0x13000000) into
LoadedSkyDesc — DayGroupData with SkyObjectData (visibility window +
arc sweep), per-keyframe SkyObjectReplaceData, and a shader-ready
SkyStateProvider builder. Sun/ambient colors are pre-multiplied by
DirBright/AmbBright so the shader never needs to know about retail's
scalar brightness field.
19 new tests (weather determinism, transition ease, environ override
tint, flash decay, dat-load conversion with fog + pre-mult colors).

When the server broadcasts a mid-run UpdateMotion with a different
ForwardSpeed (e.g. the player's RunRate changes due to stamina / skill
update), acdream must NOT restart the cycle — that would reset the
footstep cursor and look like a visible twitch. Retail handles this via
Sequence.multiply_cyclic_animation_framerate (ACE
references/ACE/Source/ACE.Server/Physics/Animation/Sequence.cs L277-L287),
which walks the cyclic tail of the queue and scales each node's
framerate by newSpeed / oldSpeed. MotionTable.change_cycle_speed
(MotionTable.cs L372-L379) is the caller from the same-motion path in
GetObjectSequence (L132-L139).
This commit:
1. Adds AnimNode.MultiplyFramerate(factor) — scales a single node's
framerate. Retail also swapped StartFrame↔EndFrame for negative
factors; acdream keeps StartFrame ≤ EndFrame as an invariant and
encodes direction via Framerate sign (see existing comment in
LoadAnimNode), so we only scale. Valid because callers only ever
pass positive factors from UpdateMotion ForwardSpeed.
2. Adds AnimationSequencer.MultiplyCyclicFramerate(factor) — walks
_firstCyclic through the tail and calls node.MultiplyFramerate(factor).
Also scales each node's Velocity and Omega by the same factor so
CurrentVelocity / CurrentOmega stay aligned with playback — matches
ACE's subtract_motion + combine_motion pair in change_cycle_speed.
3. Adds AnimationSequencer.CurrentSpeedMod public property — starts at
1.0, updated by SetCycle on both restart and mid-cycle rescale.
4. Adds a speed-change fast-path to SetCycle: when the (style, motion)
pair matches the current cycle and signs agree,
MultiplyCyclicFramerate(newSpeed/oldSpeed) is called instead of
rebuilding the queue — the cursor stays where it is and the animation
continues at the new rate.
5. Wires InterpretedMotionState.ForwardSpeed from UpdateMotion through
to SetCycle in OnLiveMotionUpdated. ACE omits the ForwardSpeed flag
when speed == 1.0 (InterpretedMotionState.cs:101-103), so we default
missing/zero values to 1.0.
Tests: 4 new sequencer tests covering MultiplyCyclicFramerate,
cursor preservation across speed changes, the same-motion-different-speed
fast-path, and the same-motion-same-speed no-op guard. 632 tests green
(was 628).

The previous tests pinned the buggy 8-byte header assumption. Now they
match ACE's actual wire format: u16 movSeq + u16 srvSeq + u8 isAuto +
1 pad (via BinaryWriter.Align based on absolute stream length 15→16).
All 166 Core.Net tests now green again.

Closes the single biggest P0 gap from r08: the AppraiseInfo blob
carried by both IdentifyObjectResponse (0x00C9) and the initial
PlayerDescription (0x0013) is now parsed end-to-end for the six core
property tables.
Wire layer:
- AppraiseInfoParser.TryParse returns a Parsed record:
(Guid, Flags, Success, PropertyBundle, SpellBook[]).
- IdentifyResponseFlags enum mirrors ACE's bitfield exactly.
- Header reader: u16 count + u16 numBuckets (ACE
PackableHashTable.WriteHeader format).
- Per-table readers: IntStatsTable, Int64StatsTable, BoolStatsTable
(u32 → bool), FloatStatsTable (f64 values), StringStatsTable
(string16L values with 4-byte pad), DidStatsTable.
- SpellBook reader: u32 count followed by count u32 spell ids, with
sanity cap at 4096 entries.
What's NOT yet parsed (deferred, noted in XML doc):
- ArmorProfile / CreatureProfile / WeaponProfile / HookProfile blobs
require porting their respective Structure classes.
- Enchantment bitfields (u16 highlight + u16 color triplets).
- ArmorLevels block.
The parser is defensive: malformed / truncated tables raise
FormatException which is caught internally; the caller gets
whatever properties parsed successfully before the error.
Tests (7 new):
- Header-only (no tables).
- IntStatsTable round-trip with mixed sign values.
- BoolStatsTable (u32 ↔ bool conversion).
- StringStatsTable with padded-length strings.
- SpellBook parsing.
- Combined flags across multiple tables.
- Truncated payload → null.
Build green, 628 tests pass (up from 621).
This unlocks the Attributes / Skills / Paperdoll UI panels once their
renderers land — every property key the server sends now gets stored
on the target ItemInstance (or — for PlayerDescription — the player's
own property bag once wired).

Outbound GameActions for XP-spending + combat-mode-change. These
complete the wire surface for the character-sheet UI: the player
clicks "spend XP on Strength," the panel calls BuildRaiseAttribute,
the session sends it, the server responds with updated PlayerDescription
or PrivateUpdateAttribute GameEvents.
Wire layer:
- BuildRaiseAttribute (0x0045): attrId u32, xpSpent u64.
- BuildRaiseVital (0x0044): vitalId u32, xpSpent u64.
- BuildRaiseSkill (0x0046): skillId u32, xpSpent u64.
- BuildTrainSkill (0x0047): skillId u32, credits u32 (note: credits
is u32 here, NOT u64 like the xpSpent variants).
- BuildChangeCombatMode (0x0053): mode enum as u32
(Undef=0, NonCombat=1, Melee=2, Missile=3, Magic=4, Peaceful=5).
Tests (5 new): byte-exact encoding of each, including the Train/
Raise size difference due to u32 vs u64 payloads.

Click-to-interact wire layer. Adds the three most common "do a thing
to an object" GameActions that the UI triggers on left-click / use-item
contexts.
Wire layer:
- InteractRequests.BuildUse (0x0036): single target guid — click a
door, loot a corpse, talk to an NPC, activate a lifestone, step on
a portal.
- InteractRequests.BuildUseWithTarget (0x0035): source + target —
key on locked door, scroll on self, salvage tool on item.
- InteractRequests.BuildTeleToLifestone (0x0063): no-arg recall. Fails
server-side if not tied; reply comes back as GameEvent WeenieError.
Server reply for Use + UseWithTarget is GameEventType.UseDone (0x01C7)
carrying a WeenieError code (0 = success). Already parsed; wiring
into a "UseDone" event on CombatState-style holder can be a follow-up.
Tests (3 new): byte-exact encoding of all three builders.
Build green, 616 tests pass (up from 613).

Client-side allegiance data model + outbound swear/break actions.
The inbound AllegianceUpdate blob (0x0020) is complex and is deferred;
the tree API here is designed so the handler can push nodes in when
the blob parser lands.
Wire layer:
- AllegianceRequests.BuildSwear (0x001D): single uint32 patronGuid.
- AllegianceRequests.BuildBreak (0x001E): single uint32 targetGuid
(works for both breaking from patron and breaking away a vassal;
the server picks behavior based on the relationship).
Core layer (AcDream.Core/Allegiance):
- AllegianceNode: Guid, Name, PatronGuid, Rank (clamped 0..10),
VassalGuids list.
- AllegianceTree: Dictionary-backed, events on TreeChanged.
- SetMonarch: registers the root (no patron).
- UpsertNode: adds/refreshes + auto-inserts into parent's vassal list.
- RemoveNode: removes from parent list too; descendants are left with
dangling patron pointers for the UI to hide (next AllegianceUpdate
refreshes).
- GetAncestors: walks up to monarch, cycle-detected for defense.
- GetDescendants: BFS-order flattening.
- AllegianceMath.ComputePassup: retail XP formula
(50+22.5×loyalty)/291 × (1+RT/730×IG/720) × earned,
clamped at 0.
Tests (11 new):
- Tree: SetMonarch fires TreeChanged, UpsertNode auto-populates parent
vassal list, rank clamp at 10, RemoveNode cleans parent list,
GetAncestors chain, cycle-safe walk, GetDescendants BFS order.
- Math: Passup known-value check (1000 XP, 10 loyalty, 100 RT/IG
days → ~963 XP), negative clamp.
- Wire: Swear + Break byte-exact encoding.
Build green, 613 tests pass (up from 602).
Next: wire inbound AllegianceUpdate (0x0020) + AllegianceInfoResponse
(0x027C) handlers once the blob parser lands. Chat "Allegiance"

Phase H.1 chat infrastructure.

Central registration helper that wires every parsed GameEvent from the
Phase F.1 dispatcher into the appropriate Core state class:
- ChannelBroadcast / Tell / CommunicationTransientString / PopupString
→ ChatLog (H.1)
- UpdateHealth / Victim / Defender / Attacker / EvasionAttacker /
EvasionDefender / AttackDone → CombatState (E.4)
- MagicUpdateSpell / MagicRemoveSpell / MagicUpdateEnchantment /
MagicRemoveEnchantment / MagicDispelEnchantment /
MagicPurgeEnchantments → Spellbook (E.5)
- WieldObject / InventoryPutObjInContainer → ItemRepository (F.2)
This is the piece that makes the dispatcher go from "thing that routes
opcodes" to "thing that populates state the UI can redraw from". Before
this, every handler had to be wired at each call site; now one call
at startup (or per-reconnect) does the whole map.
Project graph: added AcDream.Core.Net → AcDream.Core ProjectReference
so the wiring can see both the dispatcher (Net) and the state classes
(Core). Net's own tests already pull in Core indirectly, so test scope
is unchanged.
Tests (6 new, in Core.Net.Tests): verify round-trip via the actual
dispatcher. Build envelope → dispatch → assert the correct Core state
change. Covers ChannelBroadcast, UpdateHealth, MagicUpdateSpell,
WieldObject, PopupString, MagicPurgeEnchantments.
Build green, 602 tests pass (up from 596).

Retail-faithful 8-light cap selection (r13 §12) — the fixed-function
D3D pipeline's "hardware lights" constraint carried over to modern GL
via UBO-per-draw.
Core layer (AcDream.Core/Lighting):
- LightSource: Kind (Directional/Point/Spot), WorldPosition,
WorldForward, ColorLinear, Intensity, Range (hard cutoff),
ConeAngle (spot), OwnerId (entity attachment), IsLit latch.
- CellAmbientState: (AmbientColor, SunColor, SunDirection) sourced from
R12 sky state for outdoor cells or EnvCell dat for indoor cells.
- LightManager: Register/Unregister/UnregisterByOwner/Clear + Tick
per frame. Selection matches r13 §12.2 exactly:
1) Skip unlit + directional.
2) Compute DistSq for every registered point/spot.
3) Drop lights outside Range² * 1.1 (10% slack prevents pop).
4) Sort by DistSq ascending; take up to 7 (slot 0 reserved for Sun).
5) Slot 0 = Sun (Directional); slots 1..7 = nearest in-range.
Tests (9 new):
- Register/Unregister/Idempotent register.
- Tick picks top 8 by distance when 12 registered.
- Range filter drops far lights (5.0 range, 20m away).
- Range slack includes lights at exactly the boundary.
- Sun reserved at slot 0 across ticks.
- Unlit lights excluded; toggling IsLit brings them back.
- UnregisterByOwner removes all owner's lights.
- DistSq updated each tick for viewer movement.
Build green, 596 tests pass (up from 587).
Next: wire LightManager into the shader UBO pass (G.2 second commit)
and feed Sun from WorldTimeService.CurrentSunDirection per frame.

Client-side deterministic sky + weather + day/night system per R12.
Retail's model is 95% client-side: the server just delivers its
current PortalYearTicks (double, seconds since boot-seed) at login and
in TimeSync packets; the client computes everything else locally from
the constants in r12 §1.2 + ACE DerethDateTime.cs.
Core layer (AcDream.Core/World):
- DerethDateTime: retail-exact calendar (16 hours/day, 30 days/month,
12 months/year, 7620 ticks/day, 2,743,200 ticks/year). HourName enum
covers all 16 named half-hour slots (Darktide → GloamingAndHalf);
MonthName covers the 12 Derethian months (Snowreap → Frostfell).
DayFraction, CurrentHour, IsDaytime, ToCalendar.
- SkyKeyframe + SkyStateProvider: 4-keyframe default day/dawn/noon/dusk
with linear color + angular-wrap heading interpolation + slerp-like
shortest-arc lerp so heading wraps 350° → 10° don't tween backwards
through 180°. Default keyframe colors tuned to retail screenshots
(sunrise warm, noon white, sunset red, midnight deep blue).
- WorldTimeService: owns the live clock. SyncFromServer(ticks) sets
baseline; NowTicks advances by real-time elapsed. Exposes DayFraction,
CurrentSky, CurrentSunDirection, IsDaytime for the render thread.
This is the foundation Phase G.2 (dynamic lighting) consumes: lighting
uniforms are fed from CurrentSky's SunColor / AmbientColor / sun
direction, varying smoothly across the day.
Tests (16 new):
- DerethDateTime: midnight, half-day, wrap, Dawnsong, Midsong,
day/night flag at dawn vs Darktide-Half, year rollover, month
advance.
- SkyState: 4-default keyframes, noon-exact matches frame data,
midpoint lerps between neighbours, wrap across midnight doesn't
produce NaN, sun direction returns unit vector, WorldTimeService
sync + DayFraction at noon.
Build green, 587 tests pass (up from 570).

Completes the client-side combat loop: send attacks, receive server's
damage broadcasts, maintain per-entity health state for HP bars +
damage floaters. All atop Phase F.1's GameEvent dispatcher.
Wire layer:
- AttackTargetRequest (0x0008 C→S, inside 0xF7B1): targetGuid +
powerLevel + accuracyLevel + attackHeight. 28-byte body.
- GameEvents parsers for all combat notifications from r08 §4:
- VictimNotification (0x01AC) — you got hit, full details
- KillerNotification (0x01AD) — you killed X
- AttackerNotification (0x01B1) — you hit X for Y (damage%)
- DefenderNotification (0x01B2) — X hit you
- EvasionAttackerNotification (0x01B3) — X evaded
- EvasionDefenderNotification (0x01B4) — you evaded X
- AttackDone (0x01A7) — attack sequence completed
Core layer:
- CombatState: per-entity health-percent cache + typed events
(HealthChanged, DamageTaken, DamageDealtAccepted, EvadedIncoming,
MissedOutgoing, AttackDone). Each event carries enough detail for
the UI to render damage floaters, HP bars, and a combat log panel.
Server is authoritative; client only mirrors state.
The server computes damage (armor, resist, crit, hit-chance); the
client only displays results. Predictive UI like "estimated damage
at 0.75 power" still works via the existing CombatMath helper class
that was in the scaffold (r02 §5 formulas).
Tests (13 new):
- AttackTargetRequest byte-exact wire encoding
- VictimNotification / AttackerNotification / EvasionAttacker /
AttackDone round-trip parse.
- CombatState: UpdateHealth caches + fires, Victim fires DamageTaken,
Attacker fires DamageDealt, Evasion routes to right event, AttackDone
carries sequence+error, Clear resets cache.
Build green, 544 tests pass (up from 532).
