Removes the parallel direct keyboard/mouse polling that K.1a left in
GameWindow alongside the new dispatcher. Now every input flows
through InputDispatcher; legacy IsKeyPressed/KeyDown/MouseDown/MouseUp/
Scroll handlers in GameWindow are deleted (~220-line refactor).
Bindings remain acdream-current (W/S/A/D/Z/X movement, Shift run,
F-key debug surface). K.1c flips them to retail.
Pieces:
- InputDispatcher.IsActionHeld(InputAction): per-frame held-state
query for movement (W/X/A/D/Z/X/Shift/Space) so PlayerMovement-
Controller can read action state without polling raw keys.
Internally walks all bindings for the action; chord match
requires modifier mask exactness.
- InputAction adds AcdreamRmbOrbitHold (Hold-activation, RMB held
drives chase-camera orbit) and AcdreamFlyDown (Ctrl held in fly
mode for descent).
- GameWindow OnInputAction subscriber replaces the entire KeyDown
switch + per-mouse-button handlers. Single dispatcher event drives:
- F1 AcdreamToggleDebugPanel
- F2 AcdreamToggleCollisionWires
- F3 AcdreamDumpNearby
- F7 AcdreamCycleTimeOfDay
- F8 AcdreamSensitivityDown
- F9 AcdreamSensitivityUp
- F10 AcdreamCycleWeather
- F AcdreamToggleFlyMode
- Tab AcdreamTogglePlayerMode (player/fly toggle - K.1c will
reassign this to ToggleChatEntry)
- Esc EscapeKey (cancel fly mode etc.)
- Mouse wheel ScrollUp/ScrollDown (camera zoom)
- RMB held (Hold) drives orbit; LMB drag still drives orbit
camera; mouse position handled by surviving MouseMove handler
which is gated on ImGui WantCaptureMouse.
- MovementInput per-frame: reads from _inputDispatcher.IsActionHeld.
MouseDeltaX hardcoded to 0f (mouse never drives character yaw).
_playerMouseDeltaX field stays defined for chase-camera RMB-orbit
but is never consumed by movement.
- WantCaptureMouse explicit gate at the top of every surviving mouse
handler in GameWindow (defense in depth - dispatcher already gates
via IMouseSource.WantCaptureMouse).
Movement-input boundary preserved: PlayerMovementController.Update
still takes the same MovementInput struct. Existing
PlayerMovementControllerTests continue green - no regression in
motion-command byte production.
Two deviations:
1. Scroll lost magnitude going through the dispatcher (fixed-step
zoom). Acceptable - discrete wheel-tick matches retail feel
anyway.
2. Movement chords are duplicated with both ModifierMask.None and
ModifierMask.Shift (covering "shift held to run while walking
forward" etc.) so the dispatcher's modifier-strict matching
preserves the modifier-blind feel of the old IsKeyPressed
polling. Will be reshaped cleanly in K.1c when retail's
walk-modifier semantics flip (default = run, shift held = walk).
15 new tests:
- InputDispatcherIsActionHeldTests: 7 cases covering chord-held +
release + modifier-mismatch + multi-binding-for-action.
- InputDispatcherTests: 3 scroll-action cases.
- DispatcherToMovementIntegrationTests (Core.Tests): 5 cases
proving FakeKeyboardSource.Press(W) -> dispatcher.IsActionHeld ->
MovementInput.Forward -> PlayerMovementController produces the
expected motion-command bytes. Includes the regression-prevention
test that mouse-X delta value (zero vs nonzero) doesn't affect
the motion bytes.

Introduces the abstraction without changing user-visible behavior.
Existing keyboard/mouse handlers in GameWindow continue working
unchanged. The new InputDispatcher runs alongside, fires
InputAction events, and a diagnostic Console.WriteLine subscriber
proves the path is observable. K.1b cuts the existing handlers
over; K.1c flips bindings to retail.
New types in src/AcDream.UI.Abstractions/Input/:
- InputAction enum (~110 actions, doc-grouped by retail keymap
category: MovementCommands, ItemSelectionCommands, UICommands,
QuickslotCommands, Chat, Combat, Emotes, Camera, Scroll, Mouse
selection, plus Acdream-specific debug actions for the existing
F-key behaviors)
- KeyChord record struct (Silk.NET.Input.Key + ModifierMask + Device)
- ModifierMask [Flags] enum matching retail keymap bit values
(Shift=0x01, Ctrl=0x02, Alt=0x04, Win=0x08)
- ActivationType enum (Press, Release, Hold, DoubleClick, Analog)
- Binding record (chord -> action -> activation)
- InputScope enum with stack semantics (Always at bottom, Game on
top during normal play; Chat / EditField / Dialog / MeleeCombat /
MissileCombat / MagicCombat / Camera push as transient overlays)
- KeyBindings collection class with Find / ForAction / Add / Remove.
AcdreamCurrentDefaults() factory matches today's hardcoded binds
(W/S/A/D/Z/X movement, Shift run, F-key debug surface) so K.1a
doesn't change behavior. RetailDefaults() is K.1c's job; for now
it returns the same map.
- IKeyboardSource / IMouseSource - test-fakeable interfaces wrapping
Silk.NET. Both surface WantCaptureMouse / WantCaptureKeyboard
flags so the dispatcher can gate per ImGui state.
- InputDispatcher: multicast event Fired<InputAction, ActivationType>;
scope stack with PushScope/PopScope/ActiveScope; per-frame Tick()
fires Hold-type bindings for currently-held chords; mouse buttons
encoded as KeyChord with Device=1.
New adapters in src/AcDream.App/Input/:
- SilkKeyboardSource - Silk.NET IKeyboard wrapper, tracks held state
- SilkMouseSource - Silk.NET IMouse wrapper, proxies ImGui WantCapture
flags for both keyboard and mouse
GameWindow.cs:
- Constructs adapters + dispatcher in OnLoad
- Subscribes to dispatcher.Fired with diagnostic Console.WriteLine
("[input] {action} {activation}") so the path is observable in
launch.log without touching any actual game state
- Calls _inputDispatcher.Tick() per frame in OnUpdate
- Existing IsKeyPressed and event handlers unchanged
Memory crib at memory/project_input_pipeline.md describes the five
layers (Silk events -> Source interfaces -> Dispatcher -> Action
events -> Subscribers) with file paths + scope semantics + the K.1c
retail-defaults plan. Indexed in MEMORY.md.
Two deviations from plan, both documented:
1. InputDispatcher placed in UI.Abstractions/Input/ rather than
App/Input/ - it has no Silk dependencies (uses only the test-
fakeable interfaces) and the test fakes live in
UI.Abstractions.Tests. Mirrors LiveCommandBus precedent. Silk
adapters + GameWindow wiring stay in App.
2. WantCaptureKeyboard moved to IMouseSource alongside WantCaptureMouse
(the dispatcher needs both at the same point).
34 new tests covering KeyChord equality, ModifierMask flags,
KeyBindings lookup, dispatcher chord matching with modifier
mismatch rejection, Hold-type Press/Release transitions, Tick()
firing held bindings, scope stack push/pop with mismatched-pop
throwing, WantCapture* gating.

Pre-Phase K research artifact. Captures the AC retail default keymap
in two complementary forms so the upcoming InputAction enum + retail
preset (Phase K.1c) can be built byte-precise.
- docs/research/named-retail/retail-default.keymap.txt — verbatim
copy of the user's test.keymap from
~/Documents/Asheron's Call/. Human-readable text format with
every binding categorized: MovementCommands (W/X/A/D/Z/C/Q/Space/
LShift/S + Y/G/H/B postures), ItemSelectionCommands (F/T/P + 18
punctuation keys for compass/item/monster/player/fellow targeting),
UICommands (F1-F12 panel toggles, R=USE, E=Examine, Esc=close,
Shift+Esc=Logout), QuickslotCommands (1-9 + Ctrl/Alt variants for
hotbar pages), Combat / MeleeCombat / MissileCombat / MagicCombat
(mode-dependent Insert/PgUp/Delete/End/PgDn), Emotes
(U=Cry, I=Laugh, J=Wave, O=Cheer, K=Point), CameraControls (numpad
cluster), MouseCommands, ScrollableControls, EditControls,
CopyAndPasteControls, DialogBoxes. 346 lines.
- docs/research/named-retail/keymap-default.txt — binary dump of
the gmDefaultMap MasterInputMap from client_portal.dat at file id
0x14000000. Decoded via the new tools/dump-keymap utility:
scancodes + modifier flags + action IDs + activation phase per
context. Confirms the text file's bindings against the dat-shipped
default. Cross-referenced against
acclient_2013_pseudo_c.txt:405510 (ACCmdInterp::OnAction) for the
movement dispatch logic and :365889 (CPlayerSystem::OnAction) for
the targeting dispatch.
- tools/dump-keymap/ — dotnet console tool referencing
references/DatReaderWriter. Reads MasterInputMap entries from a
dat directory + emits human-readable per-context binding tables.
Reusable for future custom keymap analysis. Run with:
dotnet run --project tools/dump-keymap/dump-keymap.csproj -c Release
Default dat dir is %USERPROFILE%/Documents/Asheron's Call.

User reported typing /ls (a command-style request, not chat) gets
echoed by the server as "You say, \"/ls\"". Slash-prefix is a
COMMAND surface, never a chat surface. Filed after the same flow
that produced @help and the welcome-message work.
Behavior change at the ChatPanel submit layer:
- Any /-prefixed input whose verb isn't in our alias tables now
renders a local "[System] Unknown command: /foo. Type /help for
the list." line and is NEVER published to the bus. No SendChatCmd,
no Talk packet. The server never sees /foo.
- Known /-verbs (/say /tell /reply /retell /general /allegiance
/patron /vassals /monarch /covassals /fellowship /lookingforgroup
/trade /roleplay /society /olthoi /help /clear /framerate /loc
and friends) still flow through ChatInputParser.Parse → SendChatCmd
exactly as before.
- @-prefix unchanged: ACE's CommandManager handles unknown @ verbs
server-side and replies via SystemChat ("Unknown command: foo")
per ACE GameActionTalk.cs:21. Our @ -> / normalization for known
verbs (Phase J Tier 1) and the @-passthrough fallthrough for
unknown verbs both still apply.
ChatInputParser now exposes:
- IsKnownVerb(string verb): query against the union of every alias
table. Used by ChatPanel to discriminate "unknown verb" from
"known verb with bad args".
- GetVerbToken(string command): public alias of the existing
ExtractVerb so callers can pull the first whitespace token without
reproducing the helper.
Parse itself is unchanged — its existing fall-through (Say with
literal text) still applies for unknown /-verbs called directly via
the parser, but ChatPanel intercepts before reaching that path so
the fall-through never fires through the live submit pipeline. Tests
that directly call Parse continue to pass; the new ChatPanel-level
tests pin the unknown-command rejection.
19 new tests:
- ChatInputParserTests: 10 IsKnownVerb Theory cases + 4 GetVerbToken
Theory cases.
- ChatPanelInputTests: 5 Theory cases for Submit_UnknownSlashCommand
covering /foo, /ls, /mp <path>, /genio, and bare /.
Solution total: 1086 green (243 Core.Net + 183 UI + 660 Core),
0 warnings.
Acceptance: type /ls, /mp /path, /anything-not-known — see local
"[System] Unknown command: /xxx. Type /help for the list of
supported commands." Nothing reaches the wire.

User reported the chat input field disappearing when the chat
window was resized smaller — older entries pushed it past the
visible area. Standard ImGui chat-window pattern fixes it: scrollable
nested region for the chat tail, fixed footer for the
separator + input field below it.
IPanelRenderer extensions (Phase J Tier 3):
- BeginChild(string id, Vector2 size, bool border = false) — opens
a nested scrollable region. Size follows ImGui semantics:
0 = fill available, negative = fill available minus this much.
- EndChild() — closes the nested region.
- FrameHeightWithSpacing() — single-line widget height incl. frame
padding + item spacing. Lets panels compute footer reservations
without hardcoding pixel constants.
- SetScrollHereY(float ratio) — forces scroll within current region;
pass 1.0f to keep the latest line visible after new entries
arrive.
ImGuiPanelRenderer impls. ImGui.NET's BeginChild signature changed
across versions (third arg moved from `bool border` to
`ImGuiChildFlags`); we cast a numeric literal (0x01 = Border bit)
to sidestep the rename. FrameHeightWithSpacing maps to
ImGui.GetFrameHeightWithSpacing(); SetScrollHereY to ImGui.SetScrollHereY.
ChatPanel restructured:
- Reserves footer height = FrameHeightWithSpacing() + 6f (small pad
for the separator above the input).
- Wraps the chat tail in BeginChild("##chattail", (0, -footer))
so the inner region scrolls independently of the window.
- Tracks _lastRenderedCount across frames and calls SetScrollHereY(1f)
only when new entries appended — manual scroll-up isn't fought
against; new messages jump the view back down only when they
actually arrive.
- Header Separator removed (the BeginChild border is enough).
FakePanelRenderer extended with the four new methods + recording.
4 new tests in ChatPanelLayoutTests pin the layout invariants:
- Render order: Begin → BeginChild → ... → EndChild → Separator
→ InputTextSubmit → End.
- BeginChild size has X=0 + negative Y at least matching the
injected FrameHeightWithSpacingValue.
- SetScrollHereY fires when entries grow.
- SetScrollHereY does NOT fire when entries don't grow.

Three-tier rollout per the 2026-04-25 retail @help dump showing the
full ACE command surface. Tier 1 + most of Tier 2 in one commit.
TIER 1 - @ as / equivalent
ACE accepts both / and @ as verb prefixes (per its own help text:
"Note: You may substitute a forward slash (/) for the at symbol
(@)."). ChatInputParser now normalises @ to / for the verb-match
phase and re-enters parsing. Critical: for verbs we don't recognise
(@acehelp, @tele, @die, @version, @loc-on-server, @nonsense, ...),
the original @ is kept in the message text so ACE's CommandManager
intercepts the message server-side. If we substituted / there too,
ACE would treat it as plain Talk and broadcast it.
Result: @a hi / @tell Bob hi / @help / @clear / @reply / @retell
all route exactly like their / counterparts. @acehelp / @tele /
@version / @die etc. pass through to the server intact.
TIER 2 - client-only commands
- /retell <msg> (also @retell): resend to the last person you
tell'd. Mirrors retail @retell. ChatVM tracks
LastOutgoingTellTarget on each OnSelfSent(Tell, ...) entry —
SenderGuid==0 distinguishes outgoing echo from inbound whispers,
same way LastIncomingTellSender already worked. ChatInputParser
takes a new optional lastOutgoingTellTarget param.
- /framerate (also @framerate): prints "Framerate: 144.2 FPS"
into chat. Wired via a new ChatVM.FpsProvider Func<float>
callback set by GameWindow at construction (closes over
_lastFps). Falls back to "(provider unavailable)" if no
callback is wired (tests / pre-live).
- /loc (also @loc): prints "Location: (123.4, 567.8, 60.0)" into
chat. Wired via ChatVM.PositionProvider Func<Vector3> closing
over GetDebugPlayerPosition() in GameWindow. ACE has a server-
side @loc too; client wins here (instantaneous + uses the local
interpolated position).
ChatPanel.TryHandleClientCommand grew @ aliases for /help /clear
/framerate /loc and the new EqAny helper for case-insensitive
multi-string matching. Help text rewritten to reference the
/ <-> @ equivalence and point at @acehelp / @acecommands for ACE's
full command list.
TIER 3 - automatic (no code)
Most retail @-commands (@allegiance motd, @afk, @die, @lifestone,
@corpse, @marketplace, @pkarena, @emote/@emotes, @fillcomps,
@permit, @consent, @squelch, @unsquelch, @messagetypes, @age,
@birth, @day, @endurance, @pklite, @version, @filter, @unfilter,
@loadfile, @log, @marketplace, ...) are server-side ACE commands.
Tier 1's passthrough takes care of them automatically — they
arrive via Talk, ACE recognises the @ and intercepts, replies via
SystemChat (which our 0xF7E0 wiring renders as [System] lines).
DEFERRED
- @saveui / @loadui / @lockui: ImGui layout save/load, ~1 hr
standalone task. Filed for follow-up.
- @title <text>: rename chat window. ImGui window-id complications.
- Toggle-style @framerate (FPS overlay on/off): print-once is
simpler and matches retail's most-common usage.
30 new tests:
- ChatInputParserAtPrefixTests: 11 covering @-prefix recognition,
unknown-@ passthrough, /retell and @retell.
- ChatVMRetellAndProvidersTests: 8 covering LastOutgoingTellTarget
tracking, FpsProvider/PositionProvider callbacks, no-provider
fallback.
- ChatPanelInputTests: +3 (/framerate, @loc, @acehelp passthrough).
Solution total: 1063 green (243 Core.Net + 160 UI + 660 Core),

Phase J follow-up after a 2026-04-25 trace where typing /help
produced two identical "Unknown command: help" lines (ACE fires the
text via both GameMessageSystemChat 0xF7E0 and a paired
CommunicationTransientString 0x02EB), and the server's WeenieError
0x0026 trailer rendered cryptically as "WeenieError 0x0026".
Three small changes:
1. WeenieErrorMessages: add 0x0026 ThatIsNotAValidCommand ->
"That is not a valid command." Plus 0x0414 / 0x050F that Phase J
already added are now covered by tests too.
2. ChatLog.OnSystemMessage dedup. Track last system text + arrival
time; if a second identical text shows up within 1 second,
suppress. ACE's two-path send (gag warnings, command errors,
etc.) collapses to a single chat line. Long bursts of repeated
text still skip the duplicates without resetting the timer.
3. Client-side /help and /clear in ChatPanel. Intercepted BEFORE
the parser passes to the server bus:
- /help, /?, /h (case-insensitive) -> render local cheat-sheet
listing acdream's slash prefixes via ChatLog.OnSystemMessage.
Avoids the round-trip to ACE that produced the duplicate
"Unknown command: help" lines AND gives users discoverability.
- /clear, /cls -> drains the chat log so the panel starts empty.
New ChatVM.ShowSystemMessage() + ChatVM.Clear() expose the
minimum surface the panel needs to dispatch client-only feedback
without coupling the panel to ChatLog directly.
12 new tests:
- 3 WeenieErrorMessages template adds (0x0026 / 0x0414 / 0x050F).
- 4 ChatLog dedup cases (immediate dup, different text, triplet,
bookended-by-different-text).
- 5 ChatPanel client-command cases (/help, 3 alias variants,
/clear).
Solution total: 1033 green (243 Core.Net + 130 UI + 660 Core),
0 warnings.
Acceptance: type /help in chat -> local help banner appears, no
server round-trip, no "Unknown command: help" duplicates. Type
/clear -> chat tail empty. Welcome banner + WeenieError-templated
"You are not in an allegiance!" / "You do not belong to a
Fellowship." continue rendering once each.

Six fixes from the 2026-04-25 live verify session.
1. ServerMessage (0xF7E0) wired to ChatLog. ACE's
GameMessageSystemChat - used for the login banner "Welcome to
Asheron's Call ... powered by ACEmulator ... type @acehelp" plus
any future server broadcast - rides opcode 0xF7E0. The parser
shipped in I.5 but the WorldSession.ServerMessageReceived event
was never subscribed by GameWindow, so the welcome line was
silently dropped. Subscribed now; same wave wires the missing
EmoteHeard / SoulEmoteHeard / PlayerKilledReceived events that
I.5 also left orphan.
2. Drop optimistic /say echo + plumb local-player-guid into ChatLog.
ACE's HandleActionTalk broadcasts a HearSpeech back to the sender
too, so we were double-printing every /say (own optimistic +
server echo). New ChatLog.SetLocalPlayerGuid() pushes the chosen
character guid in (mirrors VitalsVM pattern); OnLocalSpeech
detects own-guid match and substitutes Sender="" so the formatter
's IsOwnSpeaker path renders "You say, ..." instead of
"+Acdream says, ...". Single line per /say.
3. IsOwnSpeaker check now applies to ChatKind.Channel too. Empty/
"You" sender -> "[Allegiance] You say, \"text\"" instead of the
"[Allegiance] says, \"text\"" double-space hole that Phase I.6's
OnSelfSent left when echoing legacy ChatChannel sends.
4. Long-form slash aliases: /general /allegiance /patron /vassals
/monarch /covassals /fellowship /fellow /lookingforgroup
/roleplay /rp /tr /gen, plus /s as alias for /say. Retail muscle
memory expected these; the prior parser only recognized /g /a /p
/v /m /cv /lfg /role and friends, so "/patron hello" fell
through as /say with the literal "/patron" prefix.
5. WeenieError templates filled in for the codes the user hit:
- 0x0414 YouAreNotInAllegiance -> "You are not in an allegiance!"
- 0x050F YouDoNotBelongToAFellowship -> "You do not belong to a Fellowship."
Replaces the cryptic "WeenieError 0x0414" / "0x050F" lines.
6. @ command pass-through: ACE handles @help / @acehelp / @tele etc.
server-side by intercepting Talk text with @ prefix; the user's
message isn't broadcast and ACE replies via SystemChat. Drop the
optimistic /say echo so the chat shows only the server's response
(the SystemChat wiring from #1 surfaces it as [System] {help}).
Tests:
- 11 long-form-alias Theory cases on ChatInputParser.
- 3 own-guid-substitution cases on ChatLog (own match, different
guid, pre-login fallback).
- Existing PrefixSubstring test refactored to "/genio" since the
previous "/general" stub is now a real verb.
Solution total: 1021 green (243 Core.Net + 125 UI + 653 Core),
0 warnings, 0 errors. +14 tests.
Acceptance: at login, [System] Welcome to Asheron's Call appears.
Single "You say, \"hi\"" per /say. /allegiance with no allegiance
shows [Allegiance] You say, ... + [System] You are not in an
allegiance!. /patron / /vassals / /monarch route correctly.

Three follow-up fixes from the 2026-04-25 live verify session.
1. CRITICAL: BuildTell wire field order. Our outbound layout was
[target_name, message] but ACE's GameActionTell.Handle reads
[message, target_name] (verified against
references/ACE/.../GameActionTell.cs:17-18 verbatim). Result: every
/tell since Phase I.3 has been failing with WeenieError 0x052B
(CharacterNotAvailable) because ACE was looking up the message
text as the recipient name. Swapped the field order in
ChatRequests.BuildTell so message is written first; updated the
pinned BuildTell test to expect the corrected layout. The
WorldSessionChatTests round-trip continues to pass since SendTell
delegates to BuildTell.
2. Retail-style FormatEntry. The user asked for the canonical retail
strings:
/say (own): You say, "text"
/say (incoming): Name says, "text"
/tell (own echo): You tell Caith, "text"
/tell (incoming): Caith tells you, "text"
channel: [Trade] +Acdream says, "text"
/shout (own): You shout, "text"
/shout (incoming):Name shouts, "text"
Discriminators: SenderGuid == 0 distinguishes our own outbound
echoes (set by OnSelfSent) from real incoming whispers (carry the
sender's player guid). Sender == "" or "You" distinguishes our own
/say echoes (OnLocalSpeech substitutes "You" when the wire sender
is empty per holtburger client/messages.rs:476-487).
ChatEntry gains a new ChannelName slot so Channel-kind entries
render with the friendly room name ("Trade") instead of "ch 3".
Falls back to "ch {ChannelId}" when ChannelName isn't populated
(legacy ChatChannel inbound or older callers).
3. Suppress optimistic Channel echo. The user saw duplicates per
/trade /lfg in the live trace:
[ch 0] Trade: hello <-- our optimistic
[ch 3] +Acdream: [Trade] hello <-- ACE's TurbineChat broadcast
ACE's TurbineChatHandler at Network/Handlers/TurbineChatHandler.cs
broadcasts EventSendToRoom to ALL recipients in the room including
the sender, so the canonical echo always arrives via 0xF7DE. Drop
the optimistic OnSelfSent for Turbine kinds in GameWindow's
SendChatCmd handler; trust the server. Legacy ChatChannel paths
(Fellowship / Allegiance / Patron / Monarch / Vassals / CoVassals)
keep the optimistic echo because the legacy 0x0147 broadcast may
not always come back to the sender.
Inbound TurbineChat also stops embedding "[Trade] " into the
message text — passes the friendly name out-of-band via the new
channelName parameter on ChatLog.OnChannelBroadcast.
11 tests updated for the new format strings (8 in ChatVMTests, 1 in
ChatVMCombatTests, 1 BuildTell, plus the format additions cover
incoming/outgoing variants per kind). Solution total: 1007 green
(243 + 114 + 650), 0 warnings.
Tells should now actually deliver. Channel echoes show as
[Trade] +Acdream says, "hello" without the duplicate.

Three post-launch fixes from the 2026-04-25 live verify session.
1. WeenieError display bug. Many ACE WeenieError / WeenieErrorWithString
codes are *informational*, not error-level — the user saw cryptic
"WeenieError 0x051B: General" / "WeenieError 0x051D" at login, but
those decode as "You have entered the General channel." and
"Turbine Chat is enabled." per ACE WeenieError(WithString).cs
templates. New static helper Core/Chat/WeenieErrorMessages.cs maps
~30 high-frequency codes to retail-faithful templates with `_`
placeholder substitution. ChatLog.OnWeenieError now routes through
Format(); unknown codes still fall back to "WeenieError 0xNNNN[: param]"
so nothing is silently lost. New codes can be added in 30 seconds
when the user reports one.
2. Tell target eats trailing punctuation. Retail muscle memory is
"/t Name, message" — comma is the separator. Our split-on-whitespace
pulled "Name," (with comma) as the target, server returned 0x052B
"That person is not available now." because no such character.
ChatInputParser.TryParseTargeted now strips a trailing ,;:.!? from
the target token so "/t Caith, hi" and "/t Caith hi" both work.
Added 7 Theory cases covering each separator + the long-form alias.
3. TurbineChat routing diagnostics. The user's ACE login showed the
"TurbineChatIsEnabled" + "YouHaveEnteredThe_Channel" notifications
for General/Trade/LFG, confirming TurbineChat IS active server-side.
But outbound /g /trade /lfg might still fall back to legacy
ChatChannel (which the server then rejects). Added diagnostic
Console.WriteLines so the next launch shows:
- "chat: SetTurbineChatChannels parsed enabled=true general=0x... ..."
(when ACE sends the 0x0295 channel-id table)
- "chat: outbound TurbineChat General room=0x... cookie=0x... len=N"
(when SendChatCmd routes a Turbine kind through 0xF7DE)
- "chat: outbound legacy ChatChannel Fellowship id=0x... len=N"
(when SendChatCmd uses the legacy 0x0147 path)
- "chat: SendChatCmd kind=General dropped (turbine.Enabled=false no legacy id)"
(when neither path can dispatch — usually means ACE didn't send
0x0295 yet and the kind is Turbine-only)
Sets up Bug 3 (proper outbound TurbineChat for /g /trade /lfg) for
a follow-up commit once the next live trace shows the actual flow.
18 new tests:
- WeenieErrorMessagesTests: 11 covering known templates + fallback.
- ChatInputParserTests: +7 Theory cases for trailing-punctuation strip.
Solution total: 1007 green (114 UI + 650 Core + 243 Core.Net), 0 warnings.

I.1 b131514, I.2 56037a4, I.3 8e6e5a0, I.4 f14296c, I.5 ff5ed9e,
I.6 ca968fc, I.7 3d26c8e, I.8 (this commit).
Plus Phase H.1 entry annotated to credit I.4 + I.7 for chat input
+ combat translation. D.5 / D.6 entries cross-link to the new I
surface where relevant. Three Q&A rows added to "When will my
specific complaint be fixed?".
- docs/ISSUES.md: 7 issues filed and closed in the same session
(#14 IPanelRenderer widgets, #15 DebugPanel migration, #16
LiveCommandBus, #17 ChatPanel input, #18 holtburger inbound
parity, #19 TurbineChat, #20 CombatChatTranslator). All in
Recently closed with real commit SHAs.
- CLAUDE.md: surgical update to the UI strategy paragraph (~line 35).
ImGui now hosts ALL dev/debug UI (Vitals + Chat + Debug);
StbTrueTypeSharp DebugOverlay deleted in I.2; TextRenderer +
BitmapFont retained for the future HUD-in-world (D.6); custom
retail-look toolkit (D.2b) remains the long-term retail-look
path while ImGui is the pragmatic D.2a default.
- memory/project_chat_pipeline.md (auto-loaded; in user's claude
project memory tree): new evergreen crib documenting the
ChatLog -> ChatVM -> ChatPanel + LiveCommandBus -> WorldSession
pipeline with the slash-command set + opcode coverage.
- memory/MEMORY.md: indexed line for project_chat_pipeline.
Solution state at end of Phase I:
989 tests green (107 + 639 + 243), 0 warnings, 0 errors.
+124 tests across the phase.
Closes Phase I in roadmap.

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.

Pure-docs sweep. Cross-checked 63 hand-curated entries in
acclient_function_map.md against docs/research/named-retail/symbols.json
(the PDB-derived authoritative name table) using the new helper at
tools/pdb-extract/check_function_map.py.
Findings:
- Zero entries matched address-and-name exactly. Confirms the
PDB build is from a different revision than the binary that
produced our Ghidra chunks (~0x800-0xC10 byte delta varies by
function cluster). Match by NAME, not by raw address.
- 38 entries corrected by PDB name lookup. The "Was" column
preserves the old address for traceability against existing
code comments. Old entries pointed mid-body of the actual
function; new column heads point to function starts.
- 25 entries have no PDB match. Either inlined / non-public
(no S_PUB32 record) or our hand-derived names were synthesized
from call-site analysis and don't match the MSVC mangled form
in the PDB. Several had wrong class assignments (e.g. 0x5387C0
claimed as CTransition::find_collisions, actually
CPolygon::polygon_hits_sphere). Flagged for re-derivation in
acclient_2013_pseudo_c.txt.
Pattern: kept the table format with two address columns (PDB +
legacy) so existing code references using the old addresses can
still be looked up. Added a sweep-summary section at the bottom of
the file documenting the methodology + findings.
Helper script at tools/pdb-extract/check_function_map.py is reusable
for future re-runs (re-run after every PDB regeneration / function
map edit).
Closes#9.

Files four new issues created by the 2026-04-25 PDB-discovery sprint:
#8 (DONE 2026-04-25) — pdb-extract tool, shipped 69d884a#9 (OPEN) — function-map address-correction sweep
(Phase E will close)
#10 (DONE 2026-04-25) — wire KillerNotification (0x01AD); orphan
parser at GameEvents.ParseKillerNotification
existed but was never registered. This commit
adds CombatState.OnKillerNotification +
KillLanded event, registers the dispatcher
handler, and adds a regression test.
#11 (OPEN) — spell metadata loader (spells.csv → SpellTable)
(Phase F will close)
Code change is minimal — three lines of dispatch + a 12-line
CombatState method with a typed event for future killfeed UI.
818 tests passing (+1 KillerNotification).

CLAUDE.md edits (6 surgical ranges):
- Goal section: introduce named-retail/ as primary; old chunks
remain as fallback for chunk-by-chunk address-range navigation.
- Workflow renamed to "grep named -> decompile -> verify -> port"
with a new STEP 0 GREP NAMED FIRST. Decompile demoted to a
fallback (Step 1) for the rare obfuscated/packed minority that
pseudo-C lacks.
- Function-map citation updated to point at symbols.json + the
cross-port hand-curated table.
- "Do not guess" rule strengthened: PDB has the answer for almost
everything; guessing is now negligence.
- Phase completion checklist accepts named symbols + addresses.
- Reference hierarchy table gets a new top row pointing at
docs/research/named-retail/ as the primary oracle for any
AC-specific algorithm — beats every other reference.
memory/project_named_decompilation.md (new): evergreen crib-sheet
with file inventory, grep examples, hard rules. Pattern matches
project_ui_architecture.md.
memory/project_retail_research_index.md: updated preamble to point
named-retail/ as first stop; older slices remain useful for
pseudocode + C# port sketches.
memory/project_collision_port.md: rewrote the "Decompiled ground
truth" section to put named-retail/ first, chunks second. The
"DECOMPILE FIRST" mandate becomes "GREP NAMED FIRST, then DECOMPILE
FALLBACK".
docs/architecture/acdream-architecture.md: Guiding Principle text
updated to introduce named-retail as the primary decomp source.
docs/plans/2026-04-11-roadmap.md: new Phase R block — Retail
research infrastructure. R.1 (corpus, shipped a9a01d8), R.2
(pdb-extract, shipped 69d884a), R.3 (actestclient vendored,
shipped a9a01d8). All marked SHIPPED 2026-04-25.
Auto-loaded MEMORY.md index updated with a new entry pointing at
project_named_decompilation.md so post-compaction sessions inherit
the workflow change automatically.
Acceptance verified:
- grep -c "named-retail" CLAUDE.md = 9 (>= 3 required)
- grep -c "named-retail" MEMORY.md = 1
- dotnet build green (docs-only commit, but verified)
Foundation phases A + B + C all landed. Next: Phase D files
ISSUES #8/#9/#11 + closes#10 (KillerNotification orphan parser).

Pure-Python MSF 7.00 PDB extractor (no deps, stdlib only). Reads
refs/acclient.pdb directly:
- DBI stream (3) -> symbol record stream index + section header
stream index
- Section headers stream (9) -> per-segment image VA bases
- Symbol record stream (8) -> S_PUB32 records with image VAs
- TPI stream (2) -> LF_CLASS / LF_STRUCTURE named records (not
forward-declared), with size leaf + name
Includes a best-effort MSVC C++ demangler so symbols.json is
grep-friendly:
?EnchantAttribute@CEnchantmentRegistry@@QBEHKAAK@Z
-> CEnchantmentRegistry::EnchantAttribute
Both demangled `name` + raw `mangled` emitted per entry so callers
can choose. Operator overloads, vtables, and other special forms
where a partial demangle would be misleading are kept mangled.
Outputs committed to docs/research/named-retail/:
- symbols.json (2.9 MB) — 18,366 named public function symbols
- types.json (506 KB) — 5,371 unique named class/struct records
Spot check (matches discovery agent's earlier finding):
CEnchantmentRegistry::EnchantAttribute -> 0x00594570 ✓
Updated docs/research/acclient_function_map.md header preamble to
direct readers at the new symbols.json as the authoritative name
source; the hand-curated table stays as the cross-port (ACE/ACME)
index. Several addresses there are wrong vs the PDB and will be
swept in the issue #9 close (Phase E).
Closes#8 (filed in Phase D's commit). Foundation for the address
sweep + name-driven workflows from here on.

Move the high-value retail RE artifacts from refs/ (per-developer
download cache, gitignored) into committed paths so subagents +
post-compaction sessions inherit them without round-tripping:
- docs/research/named-retail/acclient_2013_pseudo_c.txt (62 MB,
Binary Ninja named pseudo-C, 99.6% function-name recovery —
18,366 named functions out of 18,598 public symbols)
- docs/research/named-retail/acclient.h (1.7 MB / 70,719 lines,
IDA-decompiled retail struct definitions verbatim — Attribute,
SecondaryAttribute, AttributeCache, Attribute2ndTable, SkillFormula,
Enchantment, CEnchantmentRegistry with _mult_list/_add_list/_vitae,
CSpellBook, MotionState, RawMotionState, MoveToStatePack, CACQualities,
CPhysicsObj — every retail object-model layout we'd otherwise have
to guess at)
- docs/research/named-retail/acclient.c (46 MB, secondary named
decomp — IDA full-binary export with mixed FUN_/named functions
plus named struct fields the chunked Ghidra output lacks)
- docs/research/data/spells.csv (3,956 spells × 35 cols including
Family for buff stacking — issue #6 unblocked)
actestclient-master vendored at references/actestclient/ (extracted
from refs/actestclient-master-2019-01-10.zip; contains the canonical
machine-readable wire-schema messages.xml). Covered by existing
references/ gitignore — per-developer reference, not committed.
Repo precedent for committing decompiled retail content was set at
commit 4d36756 (18 MB Ghidra chunks). This adds ~110 MB more of the
same qualitative content. Ripgrep handles it in <1s.

Phase A.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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).
Visual verify
$env:ACDREAM_DEVTOOLS = "1"
dotnet run --project src\AcDream.App\AcDream.App.csproj -c Debug
Vitals window shows three bars; HP at 100%, Stam/Mana at ~95%

multiplier+additive aggregator pattern as the reference for the
fix).

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.

Filed as the one explicit post-D.2a follow-up. VitalsVM returns float?
null for Stamina/Mana because absolute values only arrive in
PlayerDescription (0x0013) today and we parse-then-discard. A small
LocalPlayerState Core class that retains the parsed fields unblocks
two more progress bars in the existing Vitals window — no new wire
work needed.

Closes Phase D.2a. Launch with ACDREAM_DEVTOOLS=1 now shows a live
ImGui "Vitals" window whose HP bar reads CombatState.GetHealthPercent
for the local player. Without the env var the branches are dead code,
no ImGui context is created, and behaviour is identical to before.
GameWindow hunks:
- fields: _imguiBootstrap / _panelHost / _vitalsVm + DevToolsEnabled
- init (OnLoad): construct bootstrap + host, register VitalsPanel
- GUID push: _vitalsVm?.SetLocalPlayerGuid(chosen.Id) at live-connect
- frame begin: _imguiBootstrap.BeginFrame(dt) after GL clear
- frame end: _panelHost.RenderAll(ctx) + _imguiBootstrap.Render() after debug overlay
- input gating: skip WASD when ImGui.GetIO().WantCaptureKeyboard
Backend pivot: Hexa.NET.ImGui → ImGui.NET + Silk.NET.OpenGL.Extensions.ImGui.
First-light integration with the Hexa backend crashed 0xC0000005 inside
Hexa.NET.ImGui.Backends.OpenGL3.ImGuiImplOpenGL3.InitNative. Root cause:
Hexa's native OpenGL3 backend resolves GL function pointers via GLFW or
SDL internally; with Silk.NET (which uses neither) the pointers are null
and the native code crashes on first use. The mitigation path was
already planned — the design doc's Risk section called a pivot to
ImGui.NET a "one-morning operation" — and that's exactly what happened.
- Packages: Hexa.NET.ImGui 2.2.9 + Hexa.NET.ImGui.Backends 1.0.18
→ ImGui.NET 1.91.6.1 + Silk.NET.OpenGL.Extensions.ImGui 2.23.0
- ImGuiBootstrapper: was static Initialize(gl)+Shutdown() wrapping
Hexa's OpenGL3 init; now an IDisposable wrapping Silk.NET's
ImGuiController instance which handles GL backend init + input
subscription in one go.
- SilkInputBridge.cs deleted (~190 LOC): ImGuiController subscribes
IKeyboard / IMouse events itself, we don't need a bespoke bridge.
- ImGuiPanelRenderer: ImGuiNET.ImGui.* calls instead of
Hexa.NET.ImGui.ImGui.*. Widget surface unchanged.
Boundary discipline is preserved — no panel imports ImGuiNET; only
ImGuiPanelRenderer does. The D.2b custom toolkit will implement the
same IPanelRenderer contract without touching panel code.
Out of scope (tracked for follow-up):
- Stam/Mana currently return float? null (VitalsVM). Absolute values
need LocalPlayerState + PlayerDescription (0x0013) parsing to be
stored rather than discarded — filed as a post-D.2a issue.
- Mouse-capture gating (WorldMouseFallThrough-style click-through
tests) — not needed until we add clickable inventory items.
Roadmap + memory + architecture doc + UI framework plan updated in the
same commit per CLAUDE.md roadmap-discipline rules. 753 tests pass
(550 Core + 192 Core.Net + 11 new UI.Abstractions), 0 build warnings.

Second piece of Phase D.2a: the ImGui-specific backend that implements
AcDream.UI.Abstractions' IPanelRenderer / IPanelHost. No GameWindow
hookup yet — compiles standalone for clean review before integration.
Packages:
* Hexa.NET.ImGui 2.2.9 (auto-generated from cimgui 1.92.2b)
* Hexa.NET.ImGui.Backends 1.0.18 (consolidated — OpenGL3 is here)
* Silk.NET.Input 2.23.0 + Silk.NET.OpenGL 2.23.0 (matches AcDream.App)
Files:
ImGuiBootstrapper.cs
One-shot static Initialize(glslVersion) / Shutdown() pair. Creates
the ImGui context, applies dark style, enables NavEnableKeyboard,
and boots ImGuiImplOpenGL3. Re-init is a no-op.
SilkInputBridge.cs
Event-driven Silk.NET -> ImGui IO bridge. Subscribes on construction;
Dispose() unsubscribes. Covers:
- KeyDown/Up -> ImGui.AddKeyEvent with modifier latching
(Ctrl/Shift/Alt/Super routed via both ModXxx flags AND named
key events so both IsKeyPressed checks and ImGui shortcut
matching work)
- KeyChar -> AddInputCharacter for text fields
- MouseMove -> AddMousePosEvent
- MouseDown/Up -> AddMouseButtonEvent (L=0, R=1, M=2)
- Scroll -> AddMouseWheelEvent (both axes)
Silk.NET.Input.Key -> ImGuiKey map covers WASD, arrows, modifiers,
letters, digits, function keys. Unmapped keys silently ignored.
BeginFrame(displaySize, dt) sets IO.DisplaySize + IO.DeltaTime.
ImGuiPanelRenderer.cs
IPanelRenderer impl — one-line wrappers on ImGui.Begin/End,
TextUnformatted, SameLine, Separator, ProgressBar. The ONLY place
Hexa.NET.ImGui types appear outside bootstrap/input plumbing. Panels
still never import ImGui.
ImGuiPanelHost.cs
IPanelHost impl. Dictionary keyed by IPanel.Id for idempotent
Register. RenderAll iterates visible panels and calls their Render.
Does NOT call ImGui.NewFrame / ImGui.Render — ownership belongs to
the caller (GameWindow) so GL state is explicit. Diagnostic `Count`
property.
No behavior change yet; next commit wires this into GameWindow behind
ACDREAM_DEVTOOLS=1 and ships the first visible VitalsPanel.
Covers the pure-logic surface of commit 1:
VitalsVMTests
* HealthPercent reads from CombatState.GetHealthPercent
* safe-default 1.0 when GUID unknown / not yet set / never updated
* SetLocalPlayerGuid reroutes lookup to the new guid (no stale cache)
* StaminaPercent / ManaPercent are null for D.2a scope
* ctor throws ArgumentNullException on null CombatState
PanelContextTests
* record-struct fields round-trip
* value-based equality
NullCommandBusTests
* Publish accepts any record type without throwing
* Instance is a true singleton
csproj template mirrors AcDream.Core.Tests (xUnit 2.9.3, Test.Sdk 17.14.1,
runner 3.1.4, coverlet 6.0.4, implicit Using Xunit). References only
AcDream.UI.Abstractions — no runtime / GL dependency, tests run fast.
Adds the backend-agnostic UI contract layer called for by the 2026-04-24
staged UI strategy (docs/plans/2026-04-24-ui-framework.md). This is the
stable layer both the Phase D.2a Hexa.NET.ImGui backend and the later
D.2b custom retail-look backend implement.
New module `src/AcDream.UI.Abstractions/`:
* IPanel — a drawable panel (id/title/visible/Render)
* IPanelHost — owns the panel list, drives per-frame dispatch
* IPanelRenderer — drawing primitives (Begin/End/Text/SameLine/
Separator/ProgressBar). Kept small + retail-friendly
on purpose — if a widget can't be expressed with
dat-sourced sprites+fonts later, don't add it here.
* ICommandBus — user-intent publisher; NullCommandBus is D.2a default
* PanelContext — per-frame record struct (DeltaSeconds + Commands)
* Panels/Vitals/
VitalsVM — reads CombatState.GetHealthPercent for the local
player. Stamina/Mana return null in D.2a; they await
a LocalPlayerState cache of PlayerDescription (0x0013)
which is filed as a follow-up issue.
VitalsPanel — first real panel. HP bar always drawn; Stam/Mana
appear automatically when the VM returns non-null.
Invariant documented in IPanel's XML doc: no `using Hexa.NET.ImGui` in
panel files, ever. If a widget needs something IPanelRenderer can't
express, the interface grows; panels never reach through.
References AcDream.Core for CombatState. Zero runtime/UI dependencies
— this project compiles headless, perfect for unit testing the
ViewModels.
No visible change yet. Next commits: (2) tests, (3) ImGui backend,
(4) GameWindow hookup + visible panel behind ACDREAM_DEVTOOLS=1.
Introduces `docs/ISSUES.md` as the tactical rolling list of known bugs +
small deferred features. Scope is strict: anything fitting in one-to-two
commits lives here; anything larger gets promoted to a Phase in the
roadmap. Complement, not replacement, of the strategic roadmap.
Schema per issue:
- Sequential integer ID (#1, #2, ...)
- Status (OPEN / IN-PROGRESS / DONE)
- Severity (HIGH / MEDIUM / LOW)
- Filed date, component, description, root cause, files, research,
acceptance
- DONE items move to "Recently closed" at the bottom with commit SHA
Four seeded issues from the 2026-04-24 sky-debug session:
#1 — Rain falls only to horizon, not to player (weather/particles)
#2 — Lightning visual not wired (dat-baked PES triggers; research done)
#3 — Client clock drifts from retail after ~10 min (periodic TimeSync)
#4 — Sky horizon-glow disabled (fog-mix skipped on sky meshes)
CLAUDE.md adds an "Issue tracking" section right after roadmap
discipline with the four maintenance rules: (1) scan OPEN at session
start, (2) add/close at session end, (3) reference IDs in commit
messages, (4) promote to a Phase if an issue grows. Calls out the
strategic-vs-tactical split so future sessions know when to reach for
the roadmap vs the issues file.
README.md gets one line pointing at `docs/ISSUES.md` below the existing
roadmap link for first-class discoverability.
No code changes; doc-only.
Landed the UI framework design in 2026-04-24-ui-framework.md yesterday;
this commit propagates the decisions across the documents that future
sessions touch first, so the three-layer pattern is discoverable without
re-reading the full plan.
Changes:
* NEW memory/project_ui_architecture.md — evergreen crib-sheet:
three-layer diagram, AcDream.UI.Abstractions contract, D.2a/D.2b
split, module layout, hard rules, why staged not pure-custom.
* CLAUDE.md: new paragraph describing the three-layer UI split, naming
AcDream.UI.Abstractions as the plugin-facing contract, pointing at
the full plan + memory crib.
* docs/architecture/acdream-architecture.md: new "UI Architecture"
companion-stack diagram after Layer 0-5 (doesn't renumber the main
stack), plus step 6a "UI tick" in Per-Frame Update Order.
* docs/plans/2026-04-11-roadmap.md Phase D tightened:
- D.2 split explicitly into D.2a (Hexa.NET.ImGui scaffold + abstraction
layer) and D.2b (custom retail-look backend, implements same contracts).
- D.3 AcFont / D.4 dat sprites / D.7 cursor flagged as D.2b dependencies.
- D.5 core panels / D.6 HUD flagged as abstraction-layer deliverables
— ship with D.2a, reskinned by D.2b.
- D.8 Sound marked superseded (shipped as Phase E.2).
- F.5 core panels + H.1 chat-window cross-references updated to say
they target AcDream.UI.Abstractions, unblocked by D.2a.
- Shipped-phases table untouched.
* docs/research/retail-ui/00-master-synthesis.md: scope note at top
clarifies the Keystone research is the D.2b (custom backend)
foundation, NOT where D.2a starts.
* ~/.claude/.../memory/MEMORY.md: one-line index entry pointing at the
new project_ui_architecture.md (so session auto-load surfaces it).
Zero code changes; doc-only. dotnet build stays green. All verification
greps pass (see plan file for exact checks).
Allows hostnames like `play.coldeve.ac` in ACDREAM_TEST_HOST. Previously
the env var fed `IPAddress.Parse` directly and threw "An invalid IP
address was specified" on anything that wasn't a literal dotted IP.
Now: `IPAddress.TryParse` first (fast path, unchanged for 127.0.0.1 /
literal IPs); on failure, fall back to `Dns.GetHostAddresses` and prefer
the first IPv4 address (ACE + retail both use IPv4 UDP exclusively).
Tested against `play.coldeve.ac:9000` — resolves to 51.79.80.150,
handshake succeeds, login to character Barris works end-to-end.
Two-stage rollout, one stable abstraction layer:
1. Short-term: Hexa.NET.ImGui as the backend. Wire up in days, iterate
game logic (chat, inventory, vitals) in weeks. Looks like a debugger,
acceptable while we prove the interaction logic end-to-end.
2. `AcDream.UI.Abstractions` — ViewModels + Commands + `IPanel` /
`IPanelRenderer` interfaces. Backend-agnostic. Plugin API targets
this layer; plugins never see ImGui.
3. Long-term: custom retail-look backend using dat assets. Swap panel
by panel. ImGui stays forever as the `ACDREAM_DEVTOOLS=1` overlay.
The new doc (`2026-04-24-ui-framework.md`) captures:
- Full design of the three-layer split
- Why Hexa.NET.ImGui over ImGui.NET + Silk.NET.OpenGL.Extensions.ImGui
(AOT readiness, tracks upstream ImGui faster, cleaner native-lib
bundling)
- Alternatives considered and ruled out (Myra, Avalonia, NoesisGUI,
RmlUi, pure custom from day one)
- Implementation order (Sprint 1 vitals HUD → Sprint 2 interaction
panels → Sprint 3 plugin API → Sprint 4+ more panels → later
custom retail-look)
- Risks + mitigations and open questions deferred to implementation
Roadmap Phase D updated with a pointer to the new plan so future
sessions start from the latest strategy, not the original
all-custom-from-day-one Phase D description.
No code changes yet. Ready to start Sprint 1 when approved.
The dome is 5 flat quads meeting at edges. Under GL_REPEAT + LINEAR
filtering, the edge pixels of each wall wrap-sample to the OPPOSITE
edge of the SAME texture (repeat wraps 1.0→0.0). Those opposite-edge
pixels never match the adjacent wall's border, so every dome seam
showed up as a visible line — four vertical wall lines plus the top
cap formed a huge cube-outline in the sky.
Switch to GL_CLAMP_TO_EDGE for any sky submesh whose SkyObject has
TexVelocityX == TexVelocityY == 0 (i.e. not a scrolling cloud layer).
Scrolling clouds keep GL_REPEAT because their UV-offset accumulates
and needs seamless wrap. One-line heuristic on TexVelocity picks the
mode per-object per draw.
User confirmed both the cube-edges artifact and the "huge square in
the sky" artifact are gone after this change. Both were the same bug
— the square was the four wall seams forming a closed rectangle
across the view.
Iteration on the sky rendering pipeline to restore stars/moon visibility
at night and fix washed-out grey daytime clouds. Key fixes:
* sky.frag: disable fog-mix on sky meshes. Retail's keyframe FogEnd
(0..400m at midnight, up to 2400m during day) is calibrated for
terrain; sky meshes are authored at radii 1050-14271m which sits
past FogEnd universally, causing every sky pixel to saturate to
fogColor (dark navy). Stars, moon, dome texture all got
obliterated. The horizon-glow trade-off is noted in the shader
comment; research item to find retail's sky-specific fog range
later.
* SkyRenderer + sky.frag: promote rep.Luminosity into uEmissive so the
vertex lighting saturates properly for bright keyframes. Retail's
FUN_0059da60 non-luminous path writes rep.Luminosity into
material.Emissive via the cache +0x3c slot; we were instead using
it as a post-fragment multiply which could only dim, never brighten.
Net effect: daytime clouds now render saturated white, dome dims
correctly at night (rep.Luminosity=0.11 → Emissive=0.11), stars
and moon unchanged.
* terrain.vert: MIN_FACTOR 0.08 -> 0.0 per retail FUN_00532440 decompile
(DAT_00796344 ambient-floor = 0.0). Back-lit terrain now falls to
pure ambient rather than getting an 8% sun floor.
New research / tooling (no runtime impact):
* docs/research/2026-04-24-lambert-brightness-split.md — retail's
ambient-brightness formula pinned from PE .rdata read + live
RetailTimeProbe capture: effAmbBright = AmbBright + |sunDir| * 0.2
where scale constant 0x0079a1e8 = 0.2f exactly.
* docs/research/2026-04-23-lightning-real.md — research note on the
dat-baked PhysicsScript-driven lightning path (Rainy DayGroup has
explicit PES-triggered flash SkyObjects with 5ms time windows).
* Corrections stapled to sky-decompile-hunt-{B,C}.md: DAT_00842778 is
DirColor, DAT_0084277c is AmbColor (the hunt docs had the swap
backwards).
* tools/RetailTimeProbe/Program.cs: extended with pid=NNNN selector,
sky global probe (DirColor/AmbColor/AmbBright/sunDir/cache.amb),
and the 0x0079a1e8 scale-factor readout.
* tools/SkyObjectInspect/: throwaway dat-inspector built by the Opus
deep-dive agent. Identified GfxObj 0x010015EF as the stars layer
(A8R8G8B8 128x128 texture, 4% bright-pixel ratio).
* src/AcDream.App/Rendering/TextureCache.cs: per-texture alpha
histogram dump under ACDREAM_DUMP_SKY=1 for diagnosing "are the
clouds decoded with proper alpha" type questions.
README: rewrite to reflect current state (playable pre-alpha rendering
Dereth with animated characters, day-night cycle, weather, etc.)
instead of the stale "Phase 0 dat inventory only" description.
All 742 tests green.
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.

Ports retail's AdminEnvirons (opcode 0xEA60) — the client-visible
weather-event channel distinct from the PlayScript path. Wire format
(chunk_006A0000.c: `[u32 opcode][u32 environChangeType]`).
EnvironChangeType range:
0x00..0x06 — fog presets (Clear/Red/Blue/White/Green/Black/Black2)
0x65..0x75 — one-shot ambient sounds (Roar, Bell, Chant, etc)
0x76..0x7B — Thunder1..6 sounds (paired with a lightning PlayScript)
Dispatch:
- WorldSession decodes the packet, fires EnvironChanged event.
- GameWindow.OnEnvironChanged:
* Fog values (0x00..0x06) → WeatherSystem.Override. The enum
values line up byte-for-byte with our EnvironOverride enum
(deliberately mirrored from retail), so a direct cast works.
* Sound values (0x65..0x7B) → console log with retail name for
now. Actual OpenAL playback needs a EnvironChangeType →
WaveData lookup (indexed via SoundTable dat), which is a
separate follow-up. The event still fires so any future
audio subscriber can plug in.
Combined with Phase 6a-6c PhysicsScript/PlayScript wiring, the
complete retail lightning pipeline is now:
server sends PlayScript(0xF754, lightningGuid, scriptId=0x33xxxxxx)
→ runs the flash script via PhysicsScriptRunner
→ CreateParticleHook spawns the flash particles
server sends AdminEnvirons(0xEA60, Thunder3Sound=0x78)
→ OnEnvironChanged logs; audio binding TBD
Whether the user's ACE sends these packets depends on the server
(ACE 2.x vanilla does NOT — Agent #5 verified no lightning opcodes in
the default emit path). With the client port complete, any ACE mod
or extension that emits the right packets will Just Work in acdream.
Build + 742 tests green.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Phase 6b — WorldSession now dispatches the PlayScript opcode (0xF754)
that retail uses for all server-triggered client-side visual effects.
Wire format per Agent #5 decompile (chunk_006A0000.c:12320-12336):
[u32 opcode=0xF754][u32 targetGuid][u32 scriptId]
New event `PlayScriptReceived(uint guid, uint scriptId)` fires on
every matching fragment. Unknown payloads (body < 12 bytes) are
silently ignored.
Phase 6c — GameWindow instantiates a PhysicsScriptRunner at startup,
subscribes to PlayScriptReceived, and ticks the runner every frame
BEFORE the ParticleSystem tick so a CreateParticleHook fired this
frame gets its emitter integrated in the same frame.
Anchor policy: use the camera's world position for the script anchor.
For Dereth-wide storm effects (lightning flashes) the camera is the
right reference frame — the flash is "around the player." Per-entity
effects (spell casts, emotes) dedupe by (scriptId, entityId) so
multiple simultaneous plays on different guids work; a follow-up will
look up the guid's last-known world pos from _worldState for accurate
per-entity anchoring.
The full pipeline now for a lightning flash:
1. ACE (or other retail-emulating server) sends
GameMessage(0xF754, lightningGuid, scriptId=0x33xxxxxx).
2. WorldSession parses: PlayScriptReceived event fires.
3. GameWindow.OnPlayScriptReceived routes to _scriptRunner.Play.
4. Runner loads the PhysicsScript from the dat, schedules every
(StartTime, AnimationHook) entry.
5. Per-frame Tick fires each hook at its scheduled time via
ParticleHookSink — CreateParticleHook spawns a particle emitter
(the flash), SoundHook plays thunder audio (Phase 5d), etc.
Set ACDREAM_DUMP_PLAYSCRIPT=1 to see each inbound PlayScript and each
hook fire as `[pes]` log lines — useful for identifying which script
IDs your ACE server actually sends.
Build + 742 tests green.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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
- replay same (scriptId, entityId) replaces, doesn't stack
- different entities run independently
- StopAllForEntity cancels that entity's scripts only
- CallPES nested spawn semantics (fires next tick)
- CallPES with Pause delays correctly
No GameWindow wiring yet — Phase 6b handles the 0xF754 packet
handler and Phase 6c plugs the runner into the frame loop.
Build + 742 tests green.

Retail applies linear vertex fog with 3D range distance
(D3DRS_FOGVERTEXMODE=3=LINEAR, D3DRS_RANGEFOGENABLE=1,
D3DRS_FOGTABLEMODE=0=NONE) to ALL mesh draws including sky. Only
FOGCOLOR / FOGSTART / FOGEND are lerped per keyframe; the mode flags
are init-only.
Verified in `docs/research/2026-04-23-sky-fog.md`:
- chunk_005A0000.c:3361-3389 device-init sets the modes.
- Sky meshes render at world origin (translation zeroed, rotation-
only) with intrinsic mesh radii in the thousands of meters
(WorldBuilder's SkyboxRenderManager.cs:247 comment confirms).
- With keyframe MaxWorldFog = 2400m, the dome saturates to
WorldFogColor at its horizon band. THAT is retail's dusk/dawn
horizon-glow mechanism.
Port:
`sky.vert` now computes the vertex fog factor:
worldPos = uModel × aPos (camera-centered since view translation=0)
dist = length(worldPos.xyz)
fogFactor = clamp((fogEnd - dist) / (fogEnd - fogStart), 0, 1)
— outputs as varying vFogFactor. 1.0 means no fog contribution,
0.0 means full fog color.
`sky.frag` applies the mix BEFORE the lightning-flash bump:
rgb = mix(uFogColor.rgb, rgb, vFogFactor)
Uses the existing SceneLighting UBO's uFogParams (x=start, y=end,
z=flash, w=mode) and uFogColor — no new uniforms, no C# change.
Expected visual:
- Dome at dawn/dusk: horizon band blends toward keyframe fogColor
(warm orange at sunset, cool blue at dawn), matching retail's
sky/fog coupling.
- Close sky objects (sun disk at typical mesh radius): unaffected
since dist < fogStart.
- Clouds at intermediate distance: partial fog blend, subtly
muting their saturation with distance.
Note on lightning: the flash channel (uFogParams.z) stays wired but
is currently always 0 because no code drives it. Agent #5 is
researching retail's real lightning mechanism (PlayScript / SetLight
PhysicsScript / other). This commit does not attempt to port it.

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.

Captures where we stand after Phase 4b and lays out the remaining
retail-faithful port work across four phases (5-8):
- Phase 5: PhysicsScript loader + runtime + sky lifecycle. Replaces
WeatherSystem's crude "DayGroup name contains Rainy → spawn rain"
shortcut with retail's actual PES-driven particle emission.
- Phase 6: Fog on sky meshes. The sky frag currently ignores fog
uniforms; retail's D3D fog applies to sky.
- Phase 7: Lightning flash trigger + thunder audio for storm keyframes.
- Phase 8: Weather / DayGroup crossfade (DAT_008427a9 / _DAT_008427b8
lerp) + AdminEnvirons override → fog crossfade.
User observation 2026-04-23 during Phase 4b verification: "Now it is
raining when it should not be." Root cause traced to the
SetKindFromDayGroupName string match firing rain particles on a "Rainy"
DayGroup regardless of whether that DayGroup actually has a visible
rain-emitting SkyObject. Proper fix requires porting PhysicsScript.
Also commits the earlier research from agent Q1-Q6:
`docs/research/2026-04-23-sky-material-state.md`.
Four parallel decompile agents are in flight as of this commit:
- PhysicsScript dat + runtime
- Sky↔PES wiring + emitter lifecycle
- Lightning + weather crossfade
- Fog on sky + vertex distance
Phase 5 implementation starts once those land.

After Phase 4 landed the per-vertex lighting formula, user observed
acdream was still "a bit too bright" vs retail. Root cause:
- My Phase 4 shader deliberately left vTint unclamped so D3D-style
overbright contributions to emissive meshes (dome has Emissive=1 → lit
could reach 2.0 with ambient + sun) would clamp naturally at the
framebuffer.
- But the frag cap was 1.2 (leaving "headroom for lightning flash"),
letting dome vertices run 20% hotter than retail's per-channel 1.0.
Retail's D3D fixed-function pipeline clamps vertex lit colour at
D3DRS_COLORCLAMP=1 (default) BEFORE texture modulation. We now match:
- Clamp `vTint = clamp(lit, 0, 1)` in sky.vert so the saturate happens
at the vertex stage, exactly like D3D.
- Drop normal-frame frag cap from 1.2 → 1.0 (the 3.0 flash relaxation
stays so lightning strobes still visibly blow out).
Expected visual:
- Dome: identical appearance (was clamping to framebuffer 1.0 anyway),
but pure retail-spec rendering so no sneaky 20% headroom.
- Clouds: unchanged (already < 1.0 at morning Rainy keyframe).
- Fragment flash during storm: unchanged — cap relaxes to 3.0 on flash.

Re-enables the Phase 2 lighting formula that was reverted in Phase 3b
due to a "blue-green-yellow sweep" across clouds. Root cause of that
earlier regression was NOT the formula — it was that we rolled the
wrong DayGroup (Sunny when retail was Cloudy), producing a sharp warm
sun against a sky that should have been rendered with diffuse
overcast light. After Phase 3g pinned the LCG multiplier to 360
(DaysPerYear) so retail + acdream agree on DayGroup, the same
per-vertex formula now faithfully reproduces retail's visuals.
The formula is verified in decompile agent Q2+Q4+Q6 results,
`docs/research/2026-04-23-sky-material-state.md`:
D3DRS_LIGHTING = ON (FUN_0059da60:10648)
D3DRS_AMBIENT = 0 (never written after init)
Material.Emissive = (Luminosity, Luminosity, Luminosity, 1)
Material.Ambient/Diffuse = defaults (≈1,1,1,1) for non-luminous
light.Ambient = keyframe AmbColor × AmbBright (via SetDirectionalLight)
light.Diffuse = keyframe DirColor × DirBright
Fixed-function lighting per vertex:
lit = Emissive + Ambient × lightAmbient + Diffuse × lightDiffuse × max(N·L, 0)
= Surface.Luminosity + AmbColor×AmbBright + DirColor×DirBright × max(N·L, 0)
Fragment: texture × lit × SkyObjectReplace.Luminosity.
Expected visual:
- Dome (Surface.Luminosity=1): `lit = 1 + amb + diff·N·L` saturates to 1
→ texture passthrough, baked gradient preserved.
- Clouds (Surface.Luminosity=0): `lit = 0 + amb + diff·N·L`
→ purple haze at night (ambient dominates, sun below horizon);
→ warm tan at dusk (ambient + warm sun on west-facing vertices);
→ pale cool gray at noon (ambient + white sun from above).
- Sun/moon (SurfaceType.Additive, Luminosity=1): same as dome +
additive blend — stays bright regardless.
The shader uniforms (uAmbientColor, uSunColor, uSunDir, uEmissive)
were already wired in the C# renderer from Phase 2; Phase 3b just
stopped using them in the shader. This commit re-activates them.
No clamp at the vertex — retail's D3D lighting allows Emissive+sum
to exceed 1, relies on the framebuffer per-channel saturation. We
keep the 1.2 ceiling in the frag (for lightning flash overbright
headroom) consistent with that convention.
No fog yet (Q1 confirmed retail leaves fog enabled for sky; will add
in a follow-up if horizon looks too bright).
