7f1bd1809a docs(research): investigation prompt for remote-anim-cycle bug
Hand-off briefing for the remaining "observed retail char's leg cycle
doesn't visibly switch in acdream" bug. Captures everything we learned
today including:

- All 8 commits shipped today (turn-sign, observed-velocity revert,
  retail-faithful tick, Commands-list SubState skip, currNode reset)
- Confirmed wins: body translation, run-in-circles, jump landing
  position + animation, turn-left direction
- Confirmed remaining bug: walk/run/idle leg cycle on observed remotes
  + residual steady-state blippiness
- Diagnostic infrastructure (FWD_WIRE, CMD_LIST, HASCYCLE, SETCYCLE,
  SEQSTATE, TURN_WIRE, OMEGA_DIAG, VEL_DIAG) and how to reproduce
- cdb live trace findings (retail uses additive add_to_queue with no
  truncate; we have ClearCyclicTail + rebuild)
- Six concrete next-step hypotheses
- A self-contained prompt for the next research agent
- Notes on rejected approaches (link-skip, full-reset, scaling hack)

d063ac884d docs(plan): Phase L.3.1+L.3.2 PositionManager + retail-faithful jump plan
6-task plan with subagent dispatch on Tasks 1, 3, 5:
- Task 1: PositionManager class + 6 unit tests (subagent)
- Task 2: Plumb IsGrounded through EntityPositionUpdate (parent, ~5 lines)
- Task 3: Retail-faithful per-frame remote tick (subagent — biggest:
  RemoteMotion.Position field + OnLivePositionUpdated rewrite [airborne
  no-op + landing transition + grounded routing] + TickAnimations rewrite
  [PositionManager.ComputeOffset + UpdatePhysicsInternal])
- Task 4: USER GATE (visual verification with retail observer)
- Task 5: Cleanup commit (subagent, parallel with 6)
- Task 6: Roadmap + spec status update (parent, parallel with 5)

Each task has TDD-style steps with exact file paths, code blocks, and
commit messages. Spec at c4446e7 lists L.3.1's already-shipped 6 commits;
this plan picks up from the revert at 1641d6e.

c4446e76fb docs(spec): Phase L.3 scope revision — combine L.3.1+L.3.2
Visual verification of L.3.1-as-originally-scoped (commit ae79e34
through e08accf) revealed that InterpolationManager corrections alone
cannot produce smooth motion — retail also relies on animation root
motion (the L.3.2 PositionManager work, originally deferred). The two
halves are functionally inseparable.

Spec changes:
- L.3.1 sub-lane absorbs L.3.2's PositionManager
- New section: PositionManager architecture (pure-function ComputeOffset
  returning Vector3 delta; combines body-local seqVel * dt rotated to
  world + InterpolationManager.AdjustOffset correction)
- New section: IsGrounded plumbing through EntityPositionUpdate (the
  PositionFlags.IsGrounded=0x04 is already parsed; just expose it)
- New section: retail-faithful jump pipeline (airborne → no-op per
  MoveOrTeleport's has_contact=0 semantics; landing detected via first
  IsGrounded=true UP after airborne)
- Acceptance criteria updated for combined scope
- Implementation order: 6 commits remaining (after the revert at 1641d6e)
- Stall-blip TAIL annotation (Task 0 resolution) folded in

L.3.3 (MoveToManager) stays a separate sub-lane.

08cb7f9614 docs(spec): Phase L.3 — Remote Entity Motion Conformance design
Port retail's InterpolationManager + MoveOrTeleport routing into
acdream so remote players, creatures, and NPCs stop popping at every
server position update and instead glide smoothly between sparse
authoritative updates the way retail does.

Three sub-lanes (incremental, each visually verifiable):
- L.3.1 — InterpolationManager core + routing + Omega + soft-snap teardown
- L.3.2 — PositionManager (root-motion + interp-offset combiner)
- L.3.3 — MoveToManager (server-controlled creature MoveTo)

This commit specs L.3.1 in detail and sketches L.3.2/L.3.3.

Research baseline (cdb live-trace + named-decomp dive 2026-05-02)
captured in docs/research/2026-05-02-remote-entity-motion/
resolved-via-cdb.md. All key constants confirmed from binary, not
guessed: MAX_PHYSICS_DISTANCE=96, MAX_INTERPOLATED_VELOCITY_MOD=2.0,
MAX_INTERPOLATED_VELOCITY=7.5, MIN_DISTANCE_TO_REACH_POSITION=0.20,
DESIRED_DISTANCE=0.05, queue cap 20, stall window 5/30%/3.

Rollout: ACDREAM_INTERP_MANAGER=1 env-var gate during development
(dual-path), single cleanup commit after visual verification removes
the flag + old hard-snap path + dead RemoteMotion soft-snap fields.

Test plan: ~15 unit tests against the InterpolationManager class
(pure-data, no game/window deps). Visual verification primary —
parallel retail observer of +Acdream walking/running/strafing/
jumping/turning, all should glide.

77b59d89e2 docs(roadmap): Phase M — Network Stack Conformance plan
Adds the Phase M planning entry: replace the happy-path WorldSession
shape with a holtburger-aligned reliable network stack while keeping
acdream's stricter checksum verification + live ACE compatibility.
Lays out M.1–M.x sub-lanes (audit/parity map, layer extraction,
reliability core, etc.).

Detailed spec to land at
docs/superpowers/specs/2026-05-02-network-stack-conformance.md
before implementation starts. Holtburger is the client-behavior
oracle for this phase.

17a9ff1158 fix(motion): jump direction, AutoPos cadence, backward/strafe wire & anim
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).

Findings + comparison vs retail/holtburger:
  docs/research/2026-05-01-retail-motion-trace/findings.md
  docs/research/2026-05-01-retail-motion-trace/fixes.md

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.

09e013b7bd docs(issues): #37 humanoid coat doesn't extend up to neck (env-var diagnostics committed)
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.

3361641655 docs(plans): #36 sky-PES dispatch port plan + .gitignore for retail-debugger scratch
Plan doc `docs/plans/2026-04-30-sky-pes-port.md` captures the full
porting plan for #36 (sky-PES dispatch chain). Three phases:
  M.1 — decomp dive (no code yet) for CallPESHook::Execute,
        CPhysicsObj::CallPES, CreateParticleHook::Execute,
        GameSky::CreateDeletePhysicsObjects, and the dynamic-spawn
        trigger (region/weather/time-of-day handler).
  M.2 — optional cdb verification with detailed args (this pointer +
        pes_id + caller stack walk).
  M.3 — implementation: persistent emitter creation at cell load,
        dynamic spawn on transitions, PES script-timeline driver,
        particle-system render wire-up.
  M.4 — live side-by-side verification.

Acceptance: aurora visible at right moments, clouds dense like retail,
storm flashes during Rainy storm windows, PES dispatch rate matches
retail's ~150/min.

.gitignore extended to suppress per-session retail-debugger scratch
files (cdb scripts, launch logs, analysis ps1 helpers). The
canonical workflow lives in CLAUDE.md "Retail debugger toolchain";
session-specific traces should not pollute the repo.

Closes #36 plan stage. Implementation work begins next session.

86e2a4dc90 docs(issues): #36 sky-PES dispatch port — live trace consolidates #2/#28/#29
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.

235de3322a feat(physics): #32 L.5 30Hz physics tick + retail debugger toolchain (#35) + Phase 3 retail-faithful kill_velocity
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.

b1af56eb19 fix(physics): L.4 — steep airborne hits slide-tangent (interim, deviates from retail)
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.

261322b48e fix(physics): #32 L.2c precipice edge-slide context
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.

b93dfe95d8 Merge feature/animation-system-complete — Phase L.1c animation MVP
21 commits porting retail's MoveToManager-equivalent client-side
behavior for server-controlled creature locomotion and combat
engagement. Shipped as MVP after live visual verification across
multiple iteration rounds with the user.

Highlights:
- 186a584 — initial Phase L.1c port: extracts Origin / target guid /
  MovementParameters block from MoveTo packets (movementType 6/7),
  adds RemoteMoveToDriver per-tick body-orientation steering with
  ±20° aux-turn-equivalent snap tolerance.
- d247aef — corrected arrival predicate semantics + 1.5 s
  stale-destination timeout for entities leaving the streaming view.
- f794832 — root-caused "creature won't stop to attack" via two
  research subagents converging on retail
  CMotionInterp::move_to_interpreted_state's unconditional
  forward_command bulk-copy. Lifted ServerMoveToActive flag clearing
  + InterpretedState bulk-copy out of substate-only branch so
  Action-class swing UMs (mt=0 ForwardCommand=AttackHigh1) clear
  stale MoveTo state and zero forward velocity.
- ff6d3d0 — RemoteMoveToDriver.ClampApproachVelocity caps horizontal
  velocity at the final-approach tick so body lands EXACTLY at
  DistanceToObject instead of overshooting through the player.
- 37de771 — bulk-copy ForwardCommand for MoveTo packets too (closed
  the regression where MoveTo creatures stayed at default
  ForwardCommand=Ready in InterpretedState and only translated via
  UpdatePosition snaps).
- 34d7f4d + e71ed73 — AnimationSequencer.HasCycle query +
  fallback chain (requested → WalkForward → Ready → no-op) at BOTH
  the OnLiveMotionUpdated path AND the spawn handler. Prevents
  ClearCyclicTail from wiping the body's cyclic tail when ACE
  CreateObject carries CurrentMotionState.ForwardCommand pointing
  to an Action-class motion (e.g. AttackHigh1 from a mid-swing
  creature) which has no cyclic-table entry — was the "torso on
  the ground" symptom for monsters seen in combat by a fresh
  observer.

Adds the Phase C.1 row to the "Phases already shipped" table and
flags the C.1 bullet in the "Phases ahead — Phase C — Polish / visuals"
section as ✓ SHIPPED. Retains C.1 entity-emitter wiring (portal swirls,
chimney smoke, fireplace flames) as a Phase C.1.5 follow-up — the data
layer is ready, only the wiring of entity-attached emitters to retail
effect IDs is deferred.

ec1bbb4f43 feat(vfx): Phase C.1 — PES particle renderer + post-review fixes
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

dotnet build green, dotnet test green: 695 / 393 / 243 = 1331 passed
(up from 1325).

186a584404 feat(anim): Phase L.1c port MoveTo path data + per-tick steer
Root-causing the user-reported "monsters disappearing some time +
laggy/jittery locomotion" via systematic-debugging Phase 1: our
UpdateMotion parser kept only speed/runRate/flags from a movementType
6/7 packet and discarded Origin (destination), targetGuid, and the
distance/walkRunThreshold/desiredHeading half of MovementParameters.
The integrator consequently held Body.Velocity at zero during MoveTo
("incomplete state" stabilizer 882a07c), so the body froze with legs
animating until UpdatePosition snap-teleported it — sometimes outside
the visible window (disappearing) — and constant-velocity drift along
the old heading between snaps produced jitter on every UP correction.

The 882a07c stabilizer was deliberately conservative because the state
WAS incomplete. Completing the data plumbing makes its restriction
moot: with the full MoveTo payload captured, the body solver has every
field retail's MoveToManager::HandleMoveToPosition (0x00529d80) reads.

Why: server re-emits MoveTo packets ~1 Hz with refreshed Origin while
chasing — verified in the live log (guid 0x800003B5 seq 0x01FE→0x0204
all show different cell/xyz floats). Those are heading updates we'd
been throwing away. With the full payload retained, the per-tick driver
steers body orientation toward Origin (±20° snap tolerance, π/2 rad/s
turn rate above tolerance) and lets apply_current_movement fill in
Velocity from the existing RunForward cycle — no new motion path,
just the right heading.

Scope is the minimum viable subset: target re-tracking, sticky/StickTo,
fail-distance progress detector, and sphere-cylinder distance are
server-side concerns we don't need (server's emit cadence handles all
of them). MoveToObject_Internal target-guid resolution is also skipped
— Origin is refreshed each packet, so the effective target tracks the
real entity even without a guid lookup.

Cross-references:
- docs/research/named-retail/acclient_2013_pseudo_c.txt — MoveToManager
  + MovementParameters::UnPackNet (0x0052ac50) + apply_run_to_command
  (0x00527be0). 18,366 named PDB symbols make this the primary oracle.
- references/ACE/Source/ACE.Server/Physics/Animation/MoveToManager.cs
  — port aid; flagged divergences (WalkRunThreshold default, set_heading
  snap, inRange one-shot) called out in the new pseudocode doc.
- docs/research/2026-04-28-remote-moveto-pseudocode.md — pseudocode +
  ACE divergence flags + out-of-scope list per CLAUDE.md mandatory
  workflow (decompile → cross-reference → pseudocode → port).

Tests: 1404 → 1412 (parser type-7 path retention + type-6 target guid
retention; driver arrival, in-tolerance snap, beyond-tolerance step,
behind-target shortest-path turn, arrival preserves orientation,
Origin→world landblock-grid arithmetic).

Pending visual sign-off — handoff stabilizer 882a07c was the last
commit the user tested.

1f82b7604e docs(plans): Phase C.1 PES particle rendering — handoff spec
Self-contained spec for the next session: PES (Particle Effect
Schedule) renderer that produces retail's "aurora light play",
portal swirls, chimney smoke, fireplace flames in one
implementation. Rolls up ISSUES.md #28 (root-caused this session
to PES on CelestialPosition.pes_id) and likely #29 (residual
cloud density gap).

Picks up after sky/weather session (merged at f7c9e88). Phase
E.3 already shipped the data layer (ParticleSystem,
EmitterDescLoader, ParticleHookSink, PhysicsScriptRunner,
VfxModel in src/AcDream.Core/Vfx/). C.1 is the visual half:
SkyDescLoader PesObjectId capture, SkyRenderer emitter spawn,
billboarded-quad GL renderer following WorldBuilder's
ParticleBatcher pattern.

Spec includes Step 0 grep targets, references in priority order
(decomp first, ACME/WorldBuilder second), the Dereth Rainy
DayGroup PES enumeration from tools/StarsProbe (notably
0x3300042C active 0.27-0.91 = "render this and confirm" target),
implementation outline (C.1.0 through C.1.6), pitfalls from
prior sessions, and the worktree setup commands.

To kick off the next session, point it at this file.

f7c9e88b6a Merge branch 'feature/sky-fixes' — sky/weather rendering retail-faithful pass
Six commits on the branch, three retail-decomp investigations
(in-house + two external code-review agents) converging on the
same root causes:

  97fc1b5 fix(sky): translucency-as-opacity + sky fog floor + additive fog-skip
  05a8a72 fix(sky): retail-faithful sun-vector magnitude for SunColor / AmbientColor
  034a684 fix(sky): partition sky pass on Properties bit 0x01, not bit 0x04
  375065b fix(meshing): Translucent flag overrides Additive blend per retail SetSurface
  646ccca feat(sky): load Setup-backed (0x020xxx) sky objects via SetupMesh.Flatten
  0c82d2c docs(issues): #28 root-caused (PES particles), #29 filed

Net effect:

  * Sun + ambient colors now use retail's |sunVec| magnitude formula
    from PrimD3DRender::UpdateLightsInternal at decomp 424118 — fixes
    blue-white sky tint at most keyframes.
  * Surface.Translucency is used DIRECTLY as opacity (not 1-x) per
    D3DPolyRender::SetSurface at decomp 425255 — fixes 3× too-bright
    cloud + correct rain alpha.
  * Sky fog re-enabled with SKY_FOG_FLOOR=0.2 mitigation — horizon
    haze visible without flat-fogging the dome at storm keyframes.
  * Additive surfaces skip fog per SetFFFogAlphaDisabled at decomp
    425295 — sun stays bright at horizon dusk/dawn.
  * Pre/post-scene partition is bit 0x01 (post-scene placement) instead
    of bit 0x04 (weather gate), per GameSky::CreateDeletePhysicsObjects
    at decomp 269036. Fixes double-rendered foreground rain.
  * Translucent flag forces alpha-blend over Additive when ClipMap is
    set, matching retail's blend resolution at decomp 425246-425260.
    Cloud surface 0x08000023 now classified correctly.
  * Setup-backed sky objects (0x020xxxxx) now load via SetupMesh.Flatten
    instead of being silently dropped by EnsureMeshUploaded.

Tests: 1227 pass.

User-visible improvements: foreground rain matches retail's
volumetric look, sky tint shifted from blue-white toward retail's
warm-gray, additive sun stays bright through horizon haze.

Outstanding:
  * Issue #28 — PES particle rendering ("aurora light play"). Now
    root-caused with implementation outline; defer to its own Phase.
  * Issue #29 — residual cloud-density gap; likely rolls into #28.

0c82d2c9e9 docs(issues): #28 root-caused (PES particles), #29 filed (residual cloud gap)
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.

449e9c3540 docs(issues): close #27 (cloud parity) — DONE-via-Fix-2
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.

47e2c151f4 docs(issues): close #1 (foreground rain) — commits d95a8d2 + 4678b3e + 3e0da49
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

clearly: cloud coverage looks faint vs retail, aurora ("northern
lights") not rendered at all. Both LOW severity (aesthetic feature

8db7a9ec28 docs(research): sky/weather investigation handoff + diagnostic tools
Captures everything learned from a long worktree iteration on the
foreground-rain bug (ISSUES.md #1 / #26) plus a new star-rendering
bug observed in the same area. The code work from that worktree
(WeatherDispatcher, EmitterDescLoader.LoadFromDat, WeatherCellRenderer,
GameWindow integration) was reverted because it didn't visibly fix
the rain bug — but the research findings + diagnostic tools are
durable and should not have to be rediscovered.

What's added:
- docs/research/2026-04-26-sky-investigation-handoff.md
  Comprehensive seed prompt for the next session. Covers:
  * Bug A: foreground rain (#26) — what's open, what's confirmed,
    what's been tried
  * Bug B: stars rendering as square in corner (NEW, user-observed)
  * 40-agent decomp scan findings — retail rain is NOT camera-
    particles, NOT server-driven, NOT screen-space; the mesh IS
    a hollow octagonal tube; only 5 weather GfxObjs in Dereth
  * Things ruled out by trial (envelope, scaling, unlit, depth-
    always alone, Setup loading)
  * Things to try next (depth+zfar combined, full render-state
    audit, frame ordering, star UV bug as easier first target)
  * Acceptance criteria for "done"

- docs/research/2026-04-26-chorizite-pr-draft.md
  Upstream PR draft for Chorizite/DatReaderWriter. Five generated
  DBObj source files reference nonexistent enum values and are
  silently excluded from the NuGet build:
  ParticleEmitterInfo, Clothing, PaletteSet, DataIdMapper,
  DualDataIdMapper. Fix: delete the duplicates. Independent of
  the rain work — benefits the AC modding ecosystem broadly.

- docs/research/2026-04-26-datreaderwriter-reference.md
  Developer reference for our DatReaderWriter usage. Version,
  types we consume, known broken types, thread-safety caveats,
  upgrade procedure, NuGet-vs-vendored decision matrix.

- tools/PesChainAudit/
  Recursive PES walker — given a 0x33xxxxxx script id, walks all
  CallPES references and dumps every hook + every referenced
  ParticleEmitter's parameters. Used to prove no weather PES
  emits rain particles.

- tools/TextureDump/
  Dumps texture pixel statistics (alpha histogram, brightness,
  max) and saves as PNG for visual inspection.

- tools/WeatherEnumerator/
  Enumerates every DayGroup in a Region, lists weather SkyObjects
  (Properties & 0x04), dumps GfxObj bounding boxes.

- tools/WeatherSetupProbe/
  Loads a Setup id, dumps each part's GfxObj + frame + scale +
  surface. Used to prove weather Setups are 5cm dummy carriers.

Worktree feature/sky-fixes is being deleted in a follow-up step.

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.

4717a5b6f7 docs(research): canonical retail keymap + dump-keymap tool
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.

Foundation for Phase K — control system overhaul. Plan documented at
~/.claude/plans/ticklish-conjuring-cake.md.

762df152d1 docs: align roadmap + ISSUES + CLAUDE.md with Phase I (UI consolidation + chat completeness)
Wraps Phase I — UI consolidation + complete chat system. All 7 prior
commits (I.1 through I.7 + I.2) are now reflected in the canonical
sources of truth.

- docs/plans/2026-04-11-roadmap.md: new "Phase I — UI consolidation +
  complete chat system" section between H and J. 8 sub-pieces all
  marked SHIPPED 2026-04-25 with their actual commit SHAs:
    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.

bb5003a849 feat(net): #7 PlayerDescriptionParser - enchantment block walker + StatMod flow
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.

b153bbe5ad feat(player): #6 fold enchantment buffs into vital max via EnchantmentMath
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.

4ceac5cb40 feat(spells): #11 SpellTable - hydrate metadata from spells.csv at startup
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.

83b020499b docs(research): #9 sweep acclient_function_map.md against PDB symbols
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.

567078803f docs(issues): #8/#9/#11 filed; #10 wired (KillerNotification)
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).

0a429a980c docs(workflow): align CLAUDE.md + memory + roadmap with named-retail foundation
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).

69d884a3d6 tools(pdb-extract): #8 PDB -> symbols.json + types.json sidecar
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.

a9a01d8ba2 docs(research): commit named retail decomp + spells.csv (foundation)
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.

Foundation for the named-retail workflow change in CLAUDE.md (next
commit). Plan at C:/Users/erikn/.claude/plans/ticklish-conjuring-cake.md

7da2a027d4 feat(player): #5 PlayerDescription parser — Stam/Mana via attribute block
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%
  (the gap is buff enchantments — filed as #6 with the holtburger
  multiplier+additive aggregator pattern as the reference for the
  fix).

d42bf5735d feat(player): #5 LocalPlayerState — Stam/Mana wired through PlayerDescription
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.

4d1b8b8aee docs(issues): #5 — VitalsPanel stam/mana null until LocalPlayerState lands
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.

55aaca7a14 feat(ui): Phase D.2a — VitalsPanel wired into GameWindow + backend pivot
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.

b9455259f0 docs: add docs/ISSUES.md tactical issue tracker + CLAUDE.md rules
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.

7e84d489d0 docs(ui): align CLAUDE.md + roadmap + memory with staged UI strategy
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).
