Closes a multi-bug knot in player motion outbound + remote inbound,
discovered via cdb live trace of retail (2026-05-01) and follow-up
visual verification.
Outbound (acdream → ACE):
- JumpAction velocity is BODY-LOCAL, not world (per retail
CPhysicsObj::get_local_physics_velocity at 0x00512140 + ACE
Player.HandleActionJump's set_local_velocity call). Was sending
world; observers saw jump rotated by player yaw.
- Capture get_jump_v_z BEFORE LeaveGround() — the latter resets
JumpExtent to 0, after which get_jump_v_z returned 0. Was sending
Z=0 in every JumpAction.
- Backward/strafe-left jumps lost their horizontal velocity because
LeaveGround → get_state_velocity returns zero for non-canonical
motion (faithful to retail's FUN_00528960; retail papers over via
adjust_motion translation, not yet ported). Compute the correct
body-local launch velocity from input directly and push it back
into the body so local prediction matches what we send.
- IsRunning HoldKey was gated on `input.Run && input.Forward`, so
strafe-run and backward-run incorrectly broadcast as walk to
observers — ACE then animated walk + dead-reckoned at walk speed
while server position moved at run speed (visible as observer
lag). Fixed: gate on any active directional axis.
- AutonomousPosition heartbeat 0.2s → 1.0s to match holtburger's
AUTONOMOUS_POSITION_HEARTBEAT_INTERVAL and the ~1Hz observed in
retail trace.
- Heartbeat now fires while in-world regardless of motion state
(matches holtburger + retail's transient_state-based gate, not
motion-based). Pre-fix the at-rest heartbeat was suppressed.
Inbound (ACE → acdream, remote retail player):
- Remote backward walk arrives as cmd=WalkForward + speed=-1.91
(retail's adjust_motion'd form). Two bugs were stacking:
1. AnimationSequencer fast-path returned without updating when
sign(speedMod) flipped while motion stayed equal — kept playing
forward at old positive framerate. Fixed: bypass fast-path on
sign change so the full re-setup runs.
2. GameWindow clamped negative speedMod to 1.0 when stuffing
InterpretedState.ForwardSpeed, making get_state_velocity
produce forward velocity. Fixed: pass speedMod through verbatim
so the dead-reckoning body translates backward.
Issue #38 filed: 30Hz physics tick produces a chase-camera smoothness
regression at 60+ FPS render. Standard render-time interpolation is
the recommended fix (separate phase).

TODO: port retail's adjust_motion (FUN_00528010) properly so
get_state_velocity works for all directions natively — would let us
drop the workaround in PlayerMovementController jump path and the
clamp in GameWindow.

Filed as #37 after a ~3 hr investigation that ruled out animation source,
backface culling/winding, palette overlay, and head-GfxObj polygons.
Confirmed:
- Stub is from part 9 (upper torso/coat) post-AnimPartChange (gfx 0x0100120D)
- Part 9's both surfaces ARE matched by our 2 TextureChanges
- Server data complete; composition formula matches ACME + retail decomp
Untested hypothesis space (next session):
- Texture decode chain (compare our SurfaceDecoder vs ACME TextureHelpers)
- Polygon-to-surface index off-by-one on part 9
- Multi-layer texture composition AC may do
- UV mapping bug
Diagnostic env vars committed to source for next-session reuse:
- ACDREAM_HIDE_PART=N — hide specific humanoid part to localize bugs
- ACDREAM_NO_CULL=1 — disable backface culling
- ACDREAM_DUMP_CLOTHING=1 — dump APC + TC + per-part Surface chain coverage
Bug was originally reported as "head/neck protrudes forward"; the apparent
forward shift turned out to be an optical illusion from the missing
coat collar. Math + cdb-ground-truth + ACME comparison confirmed the
head placement is correct retail-faithful — see #37 for the long write-up.

A 2026-04-30 cdb live trace of retail acclient.exe attached during
sky observation revealed the missing infrastructure behind acdream's
three open sky bugs (#2 lightning, #28 aurora, #29 cloud density).
Live trace over 24,576 GameSky::Draw frames:
GameSky::Draw = 24,576 (60 Hz render rate)
GameSky::UseTime = 12,288 (30 Hz — half rate)
GameSky::CreateDeletePhysicsObjects = 12,288 (30 Hz, MinQuantum gate)
CPhysicsObj::CallPES = 372 (~150/min average)
CallPESHook::Execute = 372 (1:1 with CallPES)
CreateParticleHook::Execute = 62 (15 initial + 47 burst)
CPhysicsObj::create_particle_emitter = 62 (matches CreateParticleHook)
Three concrete findings:
1. Retail HAS persistent particle emitters on celestial / sky objects.
15 created at cell load; dynamically spawned on region/weather/time
transitions (the trace caught a +47 burst on one such transition).
2. The PES script-hook system drives existing emitters periodically.
`CallPESHook::Execute` fires script-scheduled actions which call
`CPhysicsObj::CallPES` 1:1, ~150 times per minute.
3. Earlier research saying "GameSky doesn't read pes_id" was correct
in scope but missed that the dispatch chain runs through the
script-hook system (not from inside GameSky directly).
`CelestialPosition.pes_id` is consumed downstream.
Files a new issue #36 that consolidates implementation work for
all three sky bugs into one porting effort. Adds cross-references
in #2, #28, #29 pointing at #36.
Decomp anchors for next session:
CallPESHook::Execute @ 0x00526e20
CreateParticleHook::Execute @ 0x00526ec0
CPhysicsObj::CallPES @ 0x00511af0
CPhysicsObj::create_particle_emitter @ 0x0050f360
GameSky::CreateDeletePhysicsObjects @ 0x005073c0
CelestialPosition.pes_id @ struct offset +0x004
Memory file `project_retail_debugger.md` updated separately with the
sky-PES breakthrough so future sessions inherit the context.

Three intertwined changes from a single investigation session driven by
attaching cdb to a live retail acclient.exe (v11.4186, Sept 2013 EoR
build) and tracing what retail actually DOES on the steep-roof wedge
scenario the user reported in acdream.
═══════════════════════════════════════════════════════════
1. L.5 — physics-tick MinQuantum gate (PlayerMovementController)
═══════════════════════════════════════════════════════════
Retail's CPhysicsObj::update_object subdivides per-frame dt into 1/30 s
sized integration steps and SKIPS entirely when accumulated dt is below
MinQuantum. Live trace evidence:
update_object = 40,960 calls
UpdatePhysicsInternal = 25,087 calls (61%)
i.e., 39% of update_object calls return early via the MinQuantum gate.
Retail's effective physics tick rate is 30Hz even at 60+ Hz render.
acdream's PlayerMovementController bypassed the existing PhysicsBody.
update_object and called UpdatePhysicsInternal(dt) directly each render
frame, which compressed bounce-energy / gravity-tangent accumulation
into half the time and amplified our steep-roof wedge dynamics.
Fix: add `_physicsAccum` accumulator. Integrate only when accumulated
dt ≥ MinQuantum (clamped to MaxQuantum to bound stale-frame jumps).
HugeQuantum drops accumulated time to discard truly stale frames
(debugger break, GC pause). Render still runs at full rate; only the
physics step is gated.
═══════════════════════════════════════════════════════════
2. Phase 3 reset retail-faithful kill_velocity (TransitionTypes)
═══════════════════════════════════════════════════════════
Retail's reset path (acclient_2013_pseudo_c.txt:273231-273239) gates
kill_velocity on `last_known_contact_plane_valid`:
if (last_known_valid == 0) {
set_collision_normal(step_up_normal); return COLLIDED;
}
kill_velocity(this);
last_known_valid = 0;
return COLLIDED;
Earlier in this session I deviated to "unconditional kill_velocity" as
a hypothesis-driven wedge fix. The live trace then showed the
deviation CAUSED a different wedge by zeroing V every frame, leaving
the body with no tangent momentum to escape (V = (0,0,0) for 169
consecutive frames while position pre/resolved frozen). The retail-
faithful gate is restored.
Note: the gate rarely fires in normal airborne play because our L.2.4
proximity guard clears last_known_valid soon after the body separates
from its remembered floor. Live retail trace also showed
kill_velocity = 0 hits over an entire play session — same behavior. So
acdream's kill_velocity is correct as ported now.
The supporting ObjectInfo.VelocityKilled flag + StopVelocity wiring +
PhysicsEngine.ResolveWithTransition consumer that actually zeros
body.Velocity when the flag is set — these were a no-op stub before
this session and are now correctly wired. Retail anchor:
OBJECTINFO::kill_velocity → CPhysicsObj::set_velocity({0,0,0}, 0) at
acclient_2013_pseudo_c.txt:274467-274475.
═══════════════════════════════════════════════════════════
3. Retail debugger toolchain (#35)
═══════════════════════════════════════════════════════════
When the question is "what does retail actually DO at runtime?" — not
"what does retail's code SAY" — the decomp at docs/research/named-retail/
is invaluable but doesn't capture state interactions across frames.
This commit ships infrastructure to attach Windows' cdb.exe to a live
retail acclient.exe with full PDB symbols and capture state at any
breakpoint.
- tools/pdb-extract/check_exe_pdb.py — reads any PE's CodeView entry
and reports MATCH / MISMATCH against refs/acclient.pdb's GUID.
Always run before attaching cdb. The matching v11.4186 build's
GUID is 9e847e2f-777c-4bd9-886c-22256bb87f32.
- tools/pdb-extract/dump_pdb_info.py — dumps a PDB's expected
build timestamp + GUID + age. Used to figure out which acclient.exe
build pairs with our PDB.
CLAUDE.md gets a Step -1 in the development workflow ("ATTACH cdb
TO RETAIL when behavior is the question, not code") and a full
"Retail debugger toolchain" section with the workflow, sample .cdb
script structure, and watchouts (PDB names use snake_case for some
classes / PascalCase for CPhysicsObj; ; is cdb's command separator;
killing cdb kills the debuggee; high-hit-rate breakpoints lag the game).
memory/project_retail_debugger.md captures the workflow + key findings
so future sessions inherit the toolchain by reading project memory.
═══════════════════════════════════════════════════════════
4. BSPQuery Path 6 slide-tangent restored (b1af56e behavior)
═══════════════════════════════════════════════════════════
After this session's retail-strict experiments showed that retail-
faithful Path 6 (SetCollide + Phase 3 reset chain) produces a
"lands on roof in falling animation, can't slide off" half-state in
acdream — because our acdream port of step_up_slide / cliff_slide is
incomplete for grounded-on-steep movement — the L.4 slide-tangent
deviation from commit b1af56e is restored as the pragmatic ship state.
The deviation: when an airborne sphere hits a polygon whose normal Z
is below FloorZ (≈ 0.6642, slope > ~49°), project the move along the
steep face to remove the into-wall displacement, set CollisionNormal +
SlidingNormal, return Slid. Body never gets ContactPlane on the steep
poly, never gets the half-state, slides off the slope under gravity's
tangent contribution.
Retail-strict requires the deeper step_up_slide / cliff_slide audit
(filed under #32). Until that lands, slide-tangent is the right
deviation — produces user-acceptable "slide off the roof" behavior.
═══════════════════════════════════════════════════════════
Test status: 833/833 green.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Phase L.4 closes the "stuck in falling animation on a steep roof" bug
the user reported on 2026-04-30 ("I jump up, I land on it. It should not
even let me land, should just slide with a falling animation"). After
this commit the body no longer sticks to a steep roof when jumping
into it — it slides along the slope while keeping the falling animation.
Two pieces:
1. BSPQuery Path 6 steep-poly slide
When an airborne sphere hits a polygon whose world normal Z is below
FloorZ (≈ 0.6642, slope > ~49°), the previous flow was:
Path 6 SetCollide → Path 4 set_walkable → ContactPlane committed →
body "lands" on the steep poly with Contact bit + falling animation.
This left the player stuck mid-slope because OnWalkable was cleared
but Contact stayed set.
The new branch detects the steep normal in Path 6 BEFORE SetCollide
is called. Instead of entering the landing path, it removes the
into-wall component of the move (project onto the steep face), sets
CollisionNormal + SlidingNormal, and returns Slid. Same shape as
Path 5's step-up fallback and CylinderCollision. The resolver retries;
the sphere is now outside the poly; FindCollisions returns OK;
ValidateTransition commits the slid position. ContactPlane is never
set, so the body stays airborne with falling animation.
2. PlayerMovementController L.3a-bounce carve-out + Inelastic stop
Re-enables the velocity-reflection bounce when the contact normal is
upward-facing but steeper than walkable (0 < N.Z < FloorZ). The base
L.3a rule suppresses bounce on landing transitions to avoid micro-
bounce on flat terrain; that suppression also stuck the player to
too-steep roofs they shouldn't land on. This carve-out re-enables
the reflection specifically for the steep upward case.
Also lands related L.2c precipice / edge-slide work that was in flight:
- TransitionTypes EdgeSlideAfterStepDownFailed: walkable-poly-steep
cliff route + steep-ContactPlane cliff route ordering, so that
CliffSlide fires when the stored walkable polygon itself is too
steep (Path 4 had previously accepted it as a "landing" via the
permissive LandingZ threshold).
- CliffSlide reference-normal selection: prefer LastWalkable, fall back
to LastKnownContactPlane only when walkable, else use world-up. This
prevents the cross(steepN, steepN) = 0 degenerate case that left the
cliff slide as a no-op when both current and last-known were steep.
- Phase 2 / step-down branch / edge-slide branch / cliff-slide
diagnostic helpers gated on ACDREAM_DUMP_EDGE_SLIDE / ACDREAM_DUMP_STEEP_ROOF.
- Two new airborne-mover regression tests in BSPStepUpTests +
PhysicsEngineTests covering wall-slide and edge tangent motion.
DEVIATION FROM RETAIL — DOCUMENTED FOR FOLLOW-UP
The Path 6 steep slide is NOT what retail does. Retail's flow on the
same hit is:
Path 6 SetCollide (no steep check) → Path 4 find_walkable returns
nothing for steep → Phase 3 reset path: restore_check_pos +
kill_velocity → return COLLIDED → validate_transition reverts CheckPos
to CurPos and forces OK.
Net retail behavior: position reverts to pre-failed-move (typically
just below the roof in the common jump-up case), velocity zeroed,
gravity rebuilds Z next frame, body falls back down naturally with
the falling animation. The "freeze" framing I used earlier was wrong;
in the typical case retail just bounces the body off and lets gravity
take over.
Strict retail behavior would match the user's intent better in the
common case AND avoid the bounce-energy-accumulation we saw with the
slide-tangent approach (V grew to ~50 m/s in continuous-contact frames).
However, retail's behavior degenerates in the edge case of an overhead
landing onto a steep slope (body would freeze mid-air above the roof).
This commit ships the slide-tangent fix as an interim "much better"
state per user verification on 2026-04-30. Follow-up work to match
retail strictly: revert Path 6 steep-slide, audit Phase 3 reset to
ensure kill_velocity (matching OBJECTINFO::kill_velocity ->
CPhysicsObj::set_velocity({0,0,0}, 0)) actually fires, and re-test.

Port the first retail precipice-slide slice from named retail/ACE: terrain and BSP walkable hits now preserve polygon vertices, failed step-down edges back-probe to rediscover the walkable polygon, and edge-slide can run precipice/cliff slide instead of only hard-stopping.
Adds pseudocode anchors plus regression coverage for terrain polygon context and loaded-terrain boundary edge-slide.

Ports retail's ParticleEmitterInfo / Particle::Init / Particle::Update
(0x005170d0..0x0051d400) and PhysicsScript runtime to a C# data-layer
plus a Silk.NET billboard renderer. Sky-PES path is debug-only behind
ACDREAM_ENABLE_SKY_PES because named-retail decomp confirms GameSky
copies SkyObject.pes_id but never reads it (CreateDeletePhysicsObjects
0x005073c0, MakeObject 0x00506ee0, UseTime 0x005075b0).
Post-review fixes folded into this commit:
H1: AttachLocal (is_parent_local=1) follows live parent each frame.
ParticleSystem.UpdateEmitterAnchor + ParticleHookSink.UpdateEntityAnchor
let the owning subsystem refresh AnchorPos every tick — matches
ParticleEmitter::UpdateParticles 0x0051d2d4 which re-reads the live
parent frame when is_parent_local != 0. Drops the renderer-side
cameraOffset hack that only worked when the parent was the camera.
H3: Strip the long stale comment in GfxObjMesh.cs that contradicted the
retail-faithful (1 - translucency) opacity formula. The code was
right; the comment was a leftover from an earlier hypothesis and
would have invited a wrong "fix".
M1: SkyRenderer tracks textures whose wrap mode it set to ClampToEdge
and restores them to Repeat at end-of-pass, so non-sky renderers
that share the GL handle can't silently inherit clamped wrap state.
M2: Post-scene Z-offset (-120m) only fires when the SkyObject is
weather-flagged AND bit 0x08 is clear, matching retail
GameSky::UpdatePosition 0x00506dd0. The old code applied it to
every post-scene object — a no-op today (every Dereth post-scene
entry happens to be weather-flagged) but a future post-scene-only
sun rim would have been pushed below the camera.
M4: ParticleSystem.EmitterDied event lets ParticleHookSink prune dead
handles from the per-entity tracking dictionaries, fixing a slow
leak where naturally-expired emitters' handles stayed in the
ConcurrentBag forever during long sessions.
M5: SkyPesEntityId moves the post-scene flag bit to 0x08000000 so it
can't ever overlap the object-index range. Synthetic IDs stay in
the reserved 0xFxxxxxxx space.
New tests (ParticleSystemTests + ParticleHookSinkTests):
- UpdateEmitterAnchor_AttachLocal_ParticlePositionFollowsLiveAnchor
- UpdateEmitterAnchor_AttachLocalCleared_ParticleFrozenAtSpawnOrigin
- EmitterDied_FiresOncePerHandle_AfterAllParticlesExpire
- Birthrate_PerSec_EmitsOnePerTickWhenIntervalElapsed (retail-faithful
single-emit-per-frame behavior)
- UpdateEntityAnchor_WithAttachLocal_MovesParticleToLiveAnchor
- EmitterDied_PrunesPerEntityHandleTracking

Updated #28 (aurora effect) from "unknown root cause" to "PES
particles attached via CelestialPosition.pes_id". Includes the
verbatim retail header struct, the StarsProbe-confirmed list of
PES-bearing entries in Dereth Rainy DG3 (notably PES 0x3300042C
active 0.27-0.91, which is the user's Warmtide screenshot), the
implementation outline, and decomp pointers to
CPhysicsObj::InitPartArrayObject + CPartArray::CreateSetup.
Filed #29 for the residual cloud-density gap that remained after
this session's Translucent-override fix (commit 375065b) and Setup
wiring (commit 646ccca). Two follow-up hypotheses captured —
likely rolls into #28 once PES rendering lands.
Cloud rendering parity with retail confirmed visually under Phase 0 of
the #27 fix plan: launched acdream with no DG override (LCG-picked
matches retail's pick), compared cloud coverage / color / edges /
movement at the same in-game time. User verdict: "Cloud and colors look
correct."
The original #27 observation from earlier in this session was a
side-effect of the broken `effEmissive=1.0` default that saturated every
sky mesh's vTint to white. That bug, plus the orthogonal `surface.Translucency`
plumbing gap, were both repaired in commit 4678b3e:
- Fix 1 (Translucency): cloud surface 0x08000023 has Translucency=0.25,
now plumbed end-to-end → clouds at 75% opacity instead of 100%.
- Fix 2 (Luminosity): cloud surfaces have Luminosity=0.0, so post-fix
they run through `vTint = ambient + sun·N·L` instead of saturating
to white — clouds pick up the keyframe time-of-day tint.
User also flagged that acdream's clock is "a few minutes ahead" of retail
(sun higher on the horizon at the same wall-clock moment). That is the
existing #3 (`Client clock drifts from retail after ~10 minutes —
periodic TimeSync missing`), reproducing exactly as documented. Out of
scope for the sky-fixes branch.

Rain bug from `docs/research/2026-04-26-sky-investigation-handoff.md`
fully resolved this session. Three commits sequentially landed the
retail-faithful path:
3e0da49 — sky pass split + -120m weather Z offset
4678b3e — Surface.Translucency + Luminosity plumbing
d95a8d2 — delete legacy camera-attached particle emitter
Visual verification by user: rain renders as volumetric foreground,
direction matches retail when LCG-picked DayGroup matches retail's,
no cylinder rim visible looking up.
Two follow-up issues remain open from the visual-verify session:
#27 — cloud rendering parity (Translucency=0.25 partial fix landed
but cloud coverage still differs from retail, possibly
keyframe-tint related)
#28 — aurora/northern lights — research found NO evidence in retail
decomp, references, or DG composition; either misremembered
or emergent from cloud system at specific keyframes

Bug B from the sky-investigation handoff is fixed in 7b88fde — file the
Recently closed entry. Two new observations from the visual-verify
session that the user flagged when they could finally see the sky
clearly: cloud coverage looks faint vs retail, aurora ("northern
lights") not rendered at all. Both LOW severity (aesthetic feature
parity, not gameplay-breaking) and out of scope for the current
worktree, which is heading to Bug A (foreground rain, #1) next per
docs/research/2026-04-26-sky-investigation-handoff.md.

Phase K final commit. Settings panel with click-to-rebind UX on top of
the K.1+K.2 input architecture, plus the roadmap / ISSUES / memory
updates that retire Phase K.
InputDispatcher gains BeginCapture / CancelCapture / IsCapturing /
SetBindings — modal capture suppresses normal action firing for the
next chord. Esc cancels (returns sentinel default chord); modifier-only
keys don't complete capture; non-modifier key down with current
modifier mask completes.
IPanelRenderer + ImGuiPanelRenderer + FakePanelRenderer gain
BeginMainMenuBar / EndMainMenuBar / BeginMenu / EndMenu / MenuItem
primitives.
SettingsVM owns a draft copy of KeyBindings with explicit Save /
Cancel / Reset semantics. Click-to-rebind enters dispatcher capture
mode; on chord captured, conflict-detect against draft (excluding the
action being rebound itself); surface a ConflictPrompt when the chord
collides; ResolveConflict(replace=true|false) commits or reverts.
ResetActionToDefault restores a single action to RetailDefaults();
ResetAllToDefaults rebuilds the entire draft. Save invokes the
onSave callback (which writes JSON + swaps the live dispatcher's
bindings).
SettingsPanel renders 8 retail-keymap-categorized CollapsingHeader
sections (Movement, Postures, Camera, Combat, UI panels, Chat,
Hotbar, Emotes). Per action: name + current binding(s) summary +
"Rebind"/"Reset" buttons. Conflict prompt at the top when pending.
Save / Cancel / "Reset all to retail defaults" at the top.
GameWindow registers SettingsPanel + wires F11 →
ToggleOptionsPanel → IsVisible toggle, plus a top-of-frame ImGui
MainMenuBar with View → Settings/Vitals/Chat/Debug entries (calls
ImGui directly — the abstraction methods exist for backend
portability but the host doesn't own a menu-bar surface).
Tests: +37 across InputDispatcherCaptureTests (7),
IPanelRendererMainMenuBarTests (9), SettingsVMTests (13),
SettingsPanelTests (8). Solution total 1220 green.
Roadmap (docs/plans/2026-04-11-roadmap.md) appends Phase K shipped
section after Phase J with K.1a–K.3 commit SHAs. ISSUES.md files
Phase L deferred work as #L.1–#L.8 (hotbar UI, spellbook favorites,
combat-mode dispatch, F-key panels, floating chat windows, UI layout
save/load, joystick bindings, plugin input subscription) and adds
#21–#25 to Recently closed. project_input_pipeline.md updated to
shipped state. CLAUDE.md gets an input-pipeline reference.
Closes Phase K.

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).

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).

Vitals window shows three bars; HP at 100%, Stam/Mana at ~95%
(the gap is buff enchantments — filed as #6 with the holtburger
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.

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.

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.
