One PView-faithful portal-visibility pass replacing the abandoned two-pipe
(inside/outside) split (#103). Settled in brainstorm 2026-05-30:
- Full Phase U in one spec (indoor BFS + outdoor building-peering + dungeon
fixpoint + distance-priority ordering + reciprocal OtherPortalClip).
- Per-cell gate = hardware clip planes (gl_ClipDistance) + scissor pre-check
(retail's two-level model); structurally immune to the #103 global-mask flood.
- Terrain stays its own path, gated to OutsideView (retail-faithful; NOT the
handoff's "terrain as cells" sketch).
- Salvage = reuse the clip math (PortalView/ScreenPolygonClip/PortalProjection,
~36 tests), rework the builder (PortalViewBuilder), delete the stencil pipeline
+ GameWindow two-pipe orchestration. Audited keep-list preserves the real
EnvCellRenderer / BuildingId / camera-collision fixes.
Staged U.1-U.6 with three visual gates. Retail anchors + acdream file:line
injection points catalogued in the spec.

The 2026-05-18 retail-chase-camera spec scoped collision out citing "retail
doesn't raycast." Phase A8.F falsified that (SmartBox::update_viewer DOES sweep
viewer_sphere); mark the note superseded and point to the A8.F spec.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Code review found the probe passed ObjectInfoState.None; retail's
SmartBox::update_viewer calls init_object(player, 0x5c) =
IsViewer|PathClipped|FreeRotate|PerfectClip (pseudo-C :92864). PathClipped makes
the sweep hard-stop at first contact (TransitionTypes.cs:811) instead of
edge-sliding around corners (which would re-trigger the A8.F camera-cell
instability); IsViewer lets the eye pass through creatures, colliding only with
world geometry. Resolves the spec's slide-vs-stop open question. Also reset
CollideCamera in the Defaults_AreRetailValues baseline test (review: maintenance
trap). Spec §5.1/§11.1 synced.

Bite-sized TDD plan for the swept-sphere camera collision: CollideCamera flag,
ICameraCollisionProbe + PhysicsCameraCollisionProbe (reuses ResolveWithTransition),
RetailChaseCamera slot-in, GameWindow wiring, Camera-menu toggle, visual
acceptance. Also refines the spec from planning findings: the InitPath +radius
sphere-center offset (ToSpherePath/FromSpherePath z-shift) and the deterministic
probe test scope (z-offset round-trip + cellId==0 guard; collision correctness
rides the existing sweep suite + visual).

Design for porting retail's stage-2 camera collision (SmartBox::update_viewer):
sweep a 0.3 m sphere from the head-pivot to the damped eye via the existing
ResolveWithTransition engine (collides both indoor cell walls and GfxObj
building shells, e.g. the cottage cellar per #98/#101), publish the stopped
position as the eye. Fixes the A8.F flap by keeping the eye out of walls so the
camera-cell + portal side-tests stay stable. Self-skip via LocalEntityId; gated
by CameraDiagnostics.CollideCamera (default ON). Corrects the prior
retail-chase-camera spec's "no camera collision" note.

The 2026-05-28 handoff's "uncommitted A8 batch" is stale: 5dc4140 landed
the batch after the handoff. Step 0 reduces to stripping the leftover
ACDREAM_A8_DIAG_* flags (still present in RuntimeOptions + GameWindow).

Faithful port of retail PView recursive portal-clip visibility
(ConstructView/ClipPortals/GetClip) to fix the residual A8 cellar flap.
Key finding: WB has no per-portal recursion — the flat-stencil algorithm
cannot express the fix; the recursion is retail-only. Builder ports as
GL-free CPU math producing a recursively-clipped OutsideView; enforcement
maps onto the existing A8 stencil pipeline. Builds on (does not supersede)
the A8 WB full-port baseline.

Both documents retained for historical reference. The new full-WB-port
design + plan (2026-05-26-phase-a8-wb-full-port-design.md + plan, ea60d1f +

Brainstorm-approved design for the A8 R3.5 → restructure pivot. Replaces
the R3.5 v1+v2 frankenstein (terrain twice + depth-clear workaround) with
WB's RenderInsideOut order verbatim: skip initial sky+terrain when inside,
delete the depth-clear, add a stencil-gated sky step inside the indoor
branch so windows show real sky (closes R4 Issue B).
Unifies the two-flag asymmetry (cameraInsideCell lenient + cameraReallyInside
strict) into a single strict cameraInside flag via PointInCell. Grace
mechanism in CellVisibility stays alive for non-render consumers.
Six tasks ahead, in order:
RR0 — pre-restructure falsification spike (Issues A + C on main?)
RR1 — revert R3.5 v1+v2 (38d5374 + 2bfeafd)
RR2 — restructure render frame to WB-faithful order
RR3 — verify SkyRenderer doesn't toggle stencil state
RR4 — visual verification matrix (cottage/cellar/inn/dungeon + transitions)
RR5 — ship docs (close#78; file new follow-ups if pre-existing on main)
Next: superpowers:writing-plans to produce the per-task plan.
Note: the design references two predecessor docs that are currently
untracked in this worktree (entity-taxonomy + phase-a8-replan). Their
contents are read-stable on disk; committing them is a separate concern
(they belong to the prior session's work). The handoff doc this design
continues from is at f90fa2f.

Captures the brainstorm session 2026-05-24 evening after A6.P4 slice 1
(b49ed90) shipped without closing #99. Investigation surfaced the actual
root cause: doors register as a single 14cm × 20cm bounding-cylinder
approximation derived from Setup.Radius/Height fallback. Their real
collision-bearing geometry lives in per-part GfxObj BSPs (3 parts for
Setup 0x020019FF), including the threshold polygon spanning the doorway.
Retail-faithful design: every server-spawned entity registers N shadow
entries (one per CylSphere + one per Sphere + one per Part-with-BSP),
all sharing the same EntityId. UpdatePhysicsState propagates ETHEREAL
flips to all entries via the existing EntityId-iteration path. Unifies
the live-entity and landblock-static registration code paths under one
ShadowShapeBuilder.
Retail anchor: CObjCell::find_obj_collisions → CPhysicsObj::FindObjCollisions
→ CPartArray::FindObjCollisions → CPhysicsPart::find_obj_collisions →
CGfxObj::find_obj_collisions. One PhysicsObj per entity, parts iterated
internally for collision (acclient_2013_pseudo_c.txt:276776-275055).
Five-commit migration sequence; tests at three layers (builder unit tests,
registry behavior tests, live-capture regression pin). Approach A approved
by user 2026-05-24.
Spec stands on its own as M1.5 work; not formally assigned a phase letter
per CLAUDE.md's "don't invent phase numbers on the fly" rule.

Knowledge-preservation pass after the issue #98 cellar-up fix shipped
(`b3ce505`). Closes the saga's documentation loop and plans the next
phase.
Changes:
- docs/research/2026-05-23-a6-p3-issue98-comparison-harness-findings.md
Appended "Resolution 2026-05-24" section: v3 hypothesis falsified,
actual mechanism (head-bump cottage GfxObj floor poly from below)
confirmed, b3ce505 fix shipped, known door regression flagged.
Memory artifacts cross-referenced.
- docs/ISSUES.md
#98 moved to DONE with full resolution writeup + decomp anchors.
#99 filed: door regression at building thresholds (caused by
b3ce505's indoor-primary gate). Closes via A6.P4.
#100 filed: transparent rectangular patches around houses
(terrain rendering). Bisect found commit 35b37df introduced the
hiddenTerrainCells mechanism that collapses 24m outdoor cells
when buildings sit in them; cottage building only fills part of
its cell so the rest of the 24m cell shows the sky-bleeding gap.
Three fix-path options documented.
- docs/superpowers/specs/2026-05-24-phase-a6-p4-retail-shadow-architecture.md
Full A6.P4 design doc. Three-slice plan: (1) query-side portal
expansion to close#99 while preserving #98 fix, (2) port retail's
BuildShadowCellSet at registration time so per-cell semantics match
`CObjCell::find_cell_list`, (3) remove b3ce505 stopgap entirely.
Decomp anchors, file-by-file plan, risk inventory, open questions.
Memory entries written separately (out-of-tree at
~/.claude/projects/.../memory/):
- feedback_retail_per_cell_shadow_list.md
The architectural lesson: retail uses per-cell shadow_object_list
with portal-aware registration; our landblock-wide spatial
registry diverges at indoor/outdoor seams.
- feedback_apparatus_for_physics_bugs.md
The apparatus-first pattern that cracked the saga: live capture +
fixture dump + replay harness. Template for future physics bugs.
Quote rule: "when a physics bug is resisting and you catch
yourself about to ship 'fix attempt N+1 with no new evidence,'
STOP. Build the apparatus first."
- MEMORY.md index updated with both new entries.

Brainstormed + approved 2026-05-21 for M1.5 milestone work. Designs
the cdb probe spike methodology (7 retail breakpoints + new
[push-back] probe) to capture retail's per-tick BSP collision
response state at 9 indoor scenarios (4 buildings + 5 dungeon sites)
and compare against acdream. Working hypothesis: BSPQuery.AdjustSphereToPlane
or its callers over-correct vs retail, producing the family of
indoor symptoms (walls walk through, ping-pong, vibration, multi-Z
falling) plus driving the existing #90 + TryFindIndoorWalkablePlane
workarounds. A6 ships in 4 slices: P1 probe spike, P2 analysis,
P3 surgical fixes, P4 workaround removal + acceptance.
Phase O (DatPath Unification) pre-empted M1.5 and shipped 2026-05-21;
A6 resumes from Phase O state. Phase O only touched rendering/dat
code; indoor physics design is unchanged.

Plan: 7 tasks decomposing spec T2..T9 with bite-sized TDD-style steps,
exact file paths, commit-message templates, and a T4 safety-check
branch (refactor in place if ObjectMeshManager._dats call sites <=20;
fall back to thin adapter otherwise).
Spec fix: §4.1 mesh-pipeline files now correctly placed under
src/AcDream.App/Rendering/Wb/ instead of Core (ObjectMeshManager uses
Silk.NET.OpenGL types from Managed* wrappers, and CLAUDE.md forbids
Core depending on GL). §4.2's layer split (TextureHelpers in Core,
rest in App) was already correct.
Plan task order: T2 (setup) -> T5 (Core helpers, lowest risk) ->
T3 (App GL infra) -> T4 (App mesh pipeline + dat-shim) -> T7 (drop
refs + cleanup) -> T8 (visual verification) -> T9 (ship). T5 moved
earlier than spec order to validate the namespace migration flow on
small-blast-radius files before the load-bearing T4.
Self-review: all 12 spec decisions (O-D1..O-D12) mapped to plan tasks;
placeholders intentional + explained (MIT license body fetched at T2
step 4; commit-message parameters filled at task close).

O-T1 audit (REPORT-ONLY) maps acdream's transitive closure on WorldBuilder:
33 files / ~7.7K LOC across Chorizite.OpenGLSDLBackend (28 files) and
WorldBuilder.Shared (5 files). Verdict on O-Q1 (thread-model): SAFE —
adapters run render-thread only; no worker-thread access to WB code.
Spec amendments incorporated via brainstorm:
- O-D7: Refactor ObjectMeshManager to take DatCollection directly (not
via adapter). T4 safety check — fall back to thin adapter if call-site
count >20.
- O-D8: Drop LandSurfaceManager, EnvCellRenderManager, PortalRenderManager,
TerrainRenderManager from the extract list — audit confirmed not reachable
(we have our own ports or never used them).
- O-D9: Promote 3 internal types in Chorizite to public on extraction
(EmbeddedResourceReader, TextureFormatExtensions, BufferUsageExtensions).
- O-D10: Strip [MemoryPackable] from TerrainEntry (we don't serialize).
- O-D11: Namespace AcDream.Core.Rendering.Wb.* for extracted code.
- O-D12: Drop ResolveId + [indoor-upload] NULL_RESULT diagnostic block.
Task breakdown: T6 (EnvCell/portal) eliminated; T5 (stateless helpers)
shrinks to 0.5d; T4 (mesh + refactor) grows to 2.5d. Net effort estimate
holds at ~7.75d.
All originally-open spec questions are now closed (Q1/Q2/Q3/Q4) or
deferred to T3 with an explicit verify step (Q5: SixLabors.ImageSharp
reachability).

Phase O extracts the WB pieces we actually use (mesh pipeline, texture
decode, GL state, scenery, terrain blending, EnvCell/portal decode —
roughly 3-5K LOC) into src/AcDream.Core/Rendering/Wb/, swaps their
dat dependency from DefaultDatReaderWriter to our DatCollection, and
drops the WorldBuilder.Shared + Chorizite.OpenGLSDLBackend project
references. WB stays in references/ as a read reference, not as a
project dependency. MIT attribution in NOTICE.md.
Tagline: ONE thing touches the DATs.
Discipline: verbatim copy first, no "improvements" while extracting.
Refactors land in follow-up phases. Out of scope: re-porting from
retail decomp; perf optimization; API cleanup.
User direction 2026-05-21: pre-empts M1.5. M1.5 paused at its
2026-05-20 baseline; A6/A7 don't touch dat infrastructure so no
rework needed when it resumes.
Files:
- docs/superpowers/specs/2026-05-21-phase-o-dat-path-unification-design.md (new, full spec)
- docs/plans/2026-04-11-roadmap.md (Phase O block inserted before M1.5; M1.5 marked PAUSED)

Port retail's CTransition::check_other_cells (acclient_2013_pseudo_c.txt
:272717-272798) into Transition.FindEnvCollisions so the foot-sphere
sees walls in EVERY cell it overlaps, not just the one cell the player's
center is in. Closes the Holtburg inn vestibule wall walk-through
(cell 0xA9B40164 has only 4 polys; adjacent 0xA9B40157 has 23 walls
that are never queried today).
Architecture: new CellTransit.FindCellSet overload (preserves the
candidate HashSet that FindCellList currently discards), new private
Transition.CheckOtherCells method (direct port of the retail loop),
one wire-up in FindEnvCollisions between the existing primary-cell BSP
return and the synthesis fall-through. ~380 LOC total.
Out of scope: FindObjCollisions (already landblock-radius broadphased),
synthesis multi-cell search (A3's job), var_4c re-target (defer).

ISSUES #83 Phase A1. Landblock stabs (entity.Id 0xC0XXYY00+n per
LandblockLoader.cs:55) were being registered with TWO collision
shadows: the correct per-part BSP at `entity.Id*256 + partIdx`, AND a
redundant mesh-AABB-fallback cylinder at `entity.Id`. The fallback
clamped to 1.5m radius, centered at the building's mesh origin,
producing user-reported "thin air" collisions inside cottages and
within 2m of building exteriors.
The fallback was originally designed for canopy-only-BSP procedural
scenery (0x80XXYY00+n) — trees whose BSP covers the canopy but not
the trunk. Landblock stabs have full BSP coverage and don't need it.
Probe evidence (launch-thinair capture):
- 0xC0A9B479 cylinder fallback (Holtburg cottage): 104 hits in a
short capture session, all inside the cottage main room
(cell=0xA9B4013F), ~2m from the building's mesh origin.
- 0xA9B47900 BSP (the actual cottage walls): 52 legitimate hits.
Fix: one new bool _isLandblockStab + one clause in the existing
mesh-AABB-fallback gate.

Three docs from the indoor walk-miss probe spike landed in commits
27c7284..a2e7a87:
- Spec: design of the [walk-miss] + [floor-polys] diagnostic emissions
with the H1/H2/H3 disambiguation matrix.
- Plan: 3-task TDD implementation plan (flag, aggregator, emissions).
- Findings: live-capture analysis showing H3 (walkable_hits_sphere /
adjust_sphere_to_plane synthesis rejection) is the dominant defect.
817 of 876 ground-contact misses (93%) cluster at dz~0.48 m, while
the 7 HITs all sit at dz~0.46 m — a 2 cm boundary between working
and broken that points at the sphere-overlap math, not the probe
distance. H1 (multi-cell iteration missing) is real but only 3%
of misses, secondary. H2 (probe distance) ruled out.
Next step: line-by-line decomp comparison of FindWalkableInternal /
walkable_hits_sphere / adjust_sphere_to_plane against retail at
acclient_2013_pseudo_c.txt:322032 / :323006 / :326793, then design
the fix in a follow-up session.

Slice 2 of 2 in the indoor ContactPlane retention phase. Deletes
Transition.TryFindIndoorWalkablePlane + the per-frame synthesis call
+ outdoor-terrain fallthrough + 9 tests. Replaces with bare
return TransitionState.OK; matching retail's BSPTREE::find_collisions
OK path (acclient_2013_pseudo_c.txt:323938). ContactPlane is retained
via the per-tick seed at PhysicsEngine.ResolveWithTransition:583
(init_contact_plane equivalent) or refreshed by BSP Path 3 / Path 4.
Predecessor: de8ffde (Bug B, BSP world-origin fix).
Evidence: launch-cp-probe-postfix-v2.log shows 3150 MISS / 3154
indoor-walkable calls (99.87% miss rate) after Bug B, with user-visible
"stuck falling when brushing upper floor edge" symptom unchanged.

Single-call-site defect in TransitionTypes.cs:1442 — the indoor cell
BSP query invokes BSPQuery.FindCollisions without passing the cell's
world rotation or world origin. Path 3 step-down + Path 4 land write
ContactPlanes with D ≈ 0 instead of the cell's world floor Z.
320 corrupt CP writes per Holtburg session per the [cp-write] probe
capture 2026-05-20.
Fix: decompose cellPhysics.WorldTransform once, pass rotation +
translation. Mirrors the existing correct pattern at :1808 (object
BSP via FindObjCollisions).
This is slice 1 of 2 for the indoor ContactPlane retention phase.
Slice 2 (Bug A — TryFindIndoorWalkablePlane removal) deferred

Brainstormed spec for resolving the cellar-descent / 2nd-floor /
invisible-obstacle indoor collision regressions reported post-Phase 2.
Root cause: Phase 2 commit eb0f772 introduced TryFindIndoorWalkablePlane
as a stop-gap walkable-plane synthesis when the indoor BSP returns OK.
Its body does a linear first-match XY scan over cellPhysics.Resolved with
no Z-proximity test, so multi-Z indoor geometry (cellars, 2nd floors,
balconies) collapses to wrong-floor selection. Walking UP stairs works
because step_up routes through DoStepDown → TransitionalInsert(5) →
BSPQuery.FindCollisions Path 3 (StepSphereDown) which already uses
FindWalkableInternal — the retail-faithful BSP walkable-finder. The
linear scan only fires in the OK-no-wall branch.
Fix: route TryFindIndoorWalkablePlane through the existing
FindWalkableInternal via a thin new BSPQuery.FindWalkableSphere wrapper.
Extends FindWalkableInternal's signature to expose the hit polyId
(dictionary key, since ResolvedPolygon doesn't carry its own id). Threads
the foot-sphere radius through TryFindIndoorWalkablePlane's signature
(was hardcoded to nothing — used the localFootCenter alone). Deletes
the now-dead PointInPolygonXY helper.
Awaiting user spec review before plan.

Brainstormed spec for the follow-up to Cluster A: port retail's portal-graph
cell traversal to replace Phase D's AABB containment shortcut. Closes
ISSUES.md #87 and the remaining wall-collision parts of #84 + #85 — indoor
walking with walls that block from inside, walking through doors that
updates CellId.
Scope: all three transition types (indoor↔indoor, indoor↔outdoor,
outdoor→indoor). AABB containment deleted entirely; portal traversal is the
only path.
Key data references: docs/research/acclient_indoor_transitions_pseudocode.md
(2026-04-13) has the entire algorithm already documented from ACE source
cross-referenced against the retail header. BSPQuery.PointInsideCellBsp is
already wired (just unused).

Brainstormed spec for the next indoor follow-up phase: surfacing root
causes for ISSUES.md #84 (blocked by air) + #85 (pass through walls
outside→in) + #86 (click selection penetrates walls). Diagnostic-first
single capture pass; one [indoor-bsp] probe in FindEnvCollisions, then
surgical fixes (one commit per issue). Mirrors the indoor cell rendering
Phase 1+2 pattern that landed earlier today.
#86's root cause is already pinned by code reading (WorldPicker has no
cell-BSP test) — its fix is structural and doesn't need capture data.
#78 (outdoor stabs through floor) is in the same handoff cluster but
defers to a separate phase — different code path (render visibility).

Three components:
1. WbMeshAdapter wraps the PrepareMeshDataAsync task with a continuation
that surfaces faulted-task exceptions + null-result cases for EnvCell
IDs only (gated by ProbeIndoorUploadEnabled). Two new log shapes:
[indoor-upload] FAILED cellId=0x... exception=<TypeName>: <Message>
stack=[<top 3 frames>]
[indoor-upload] NULL_RESULT cellId=0x...
2. Capture procedure: re-launch at Holtburg with the probe on, grep for
FAILED/NULL_RESULT lines, get definitive per-cell cause for the 26
missing-completion cells from Phase 1's capture.
3. Targeted fix: code change matching whichever exception type / null
pattern dominates. Fix shape is data-driven — see the contingency
table in the spec.
WB's catch at ObjectMeshManager.cs:589 already calls _logger.LogError,
but WbMeshAdapter constructs the manager with NullLogger.Instance, so
the log is dropped. Our continuation surfaces the same data scoped to
EnvCells only (avoids the thousands of GfxObj/Setup log lines a real
logger would emit during landblock streaming).

User feedback: "add the probes you need. Better info, better code."
Original spec had a single ACDREAM_PROBE_INDOOR=1 with vague "log
lookup results" guidance. Replaced with five individually-toggleable
probes, each with:
- Specific env var name + DebugPanel checkbox name.
- Concrete log-line format.
- Exact code site to instrument.
- The hypothesis it disambiguates.
Probe set:
- ACDREAM_PROBE_INDOOR_WALK — dispatcher entity walk per cell
- ACDREAM_PROBE_INDOOR_LOOKUP — render-data lookup hit/miss + SetupParts
- ACDREAM_PROBE_INDOOR_UPLOAD — WB upload result (requested + completed)
- ACDREAM_PROBE_INDOOR_XFORM — composed world transform for cell geom
- ACDREAM_PROBE_INDOOR_CULL — visibility/frustum filter decisions
Plus ACDREAM_PROBE_INDOOR_ALL master toggle.
Implementation outline added: new RenderingDiagnostics static class
(mirrors L.2a's PhysicsDiagnostics pattern), DebugPanel subsection,
edits to WbDrawDispatcher + WbMeshAdapter.
Acceptance criteria refreshed.

Initial brainstorm assumed N.5 retirement broke EnvCell rendering by
leaving _pendingCellMeshes unconsumed. Pivoted mid-brainstorm:
- WB's PrepareMeshData routes EnvCell dat-record types to
PrepareEnvCellMeshData (ObjectMeshManager.cs:557) which produces an
IsSetup=true ObjectMeshData with the floor mesh as EnvCellGeometry.
- WbDrawDispatcher correctly handles IsSetup=true (line 607-621) by
iterating SetupParts and drawing each.
- DefaultDatReaderWriter loads region cell dats; ResolveId resolves
envCellId correctly.
- LandblockSpawnAdapter calls IncrementRefCount on every entity's
GfxObjId, including envCellId for cell entities. ServerGuid==0 passes
the atlas-tier filter.
Chain is structurally intact. The bug is somewhere subtler.
Spec pivots to a diagnostics-first phase: ACDREAM_PROBE_INDOOR=1
captures per-frame cell-entity walk + render-data lookup + SetupParts
traversal + composed-transform values. Six hypotheses (WB silently
returns null, empty batches, cull bug, double-spawn, transform
double-apply, dispatcher MeshRefs mismatch) match six concrete fix
shapes. Phase 2 design follows the probe data.
This is more honest than the original "build a new upload path"
design, which would have hidden the actual bug.

Spec for porting retail's CameraManager + CameraSet behavior to a new
RetailChaseCamera class, controlled by a CameraDiagnostics toggle so the
user can A/B against legacy ChaseCamera. Covers six retail behaviors:
exponential damping (stiffness*dt*10), 5-frame velocity-averaged slope
alignment, mouse low-pass (0.25s window), held-key offset integration,
auto-fade <0.45m, and independent translation/rotation stiffness rates.

Closes#63, #69, #74, #75. Replaces the chain of Commit-B workarounds
that compensated for ACE's MoveToChain getting cancelled by a leaked
user-MoveToState packet during inbound auto-walk. The fix is
architectural — auto-walk drives the body directly from the
server-supplied path data, no player-input synthesis, no spurious
wire-packet transitions, no grace-period band-aid.
Architectural change (closes#75):
PlayerMovementController.ApplyAutoWalkOverlay → DriveServerAutoWalk.
- Steps Yaw toward target at retail-faithful turn rates.
- Computes desired forward velocity from path runRate.
- Calls _motion.DoMotion(WalkForward, speed) directly for the
motion-interpreter state (drives animation cycle).
- Sets _body.set_local_velocity directly when grounded.
- Returns true to gate the user-input motion + velocity section
in Update so user-input flow doesn't overwrite auto-walk
velocity or motion state.
Mirrors retail's MovementManager::PerformMovement case 6 (decomp
0x00524440) which never touches the user-input pipeline during
server-controlled auto-walk.
Wire-layer guard at GameWindow.cs:6419 retained as a SEMANTIC
statement (`if (result.MotionStateChanged && !IsServerAutoWalking)`):
user-MoveToState packets are for user-driven motion intent. During
server-controlled auto-walk, the motion-state transitions caused by
the animation override (RunForward / WalkForward / TurnLeft /
TurnRight cycles) must not leak as user-cancellation packets. This
is NOT the deleted 500ms grace-period band-aid; it's the wire-layer
expressing the user-vs-server motion split.
Animation plumbed for auto-walk phases (closes#69):
- Moving forward → WalkForward (speed=1.0) / RunForward (speed=runRate)
- Turn-first phase → TurnLeft / TurnRight (sign of yawStep)
- Aligned-but-pre-step / arrival → no override (idle)
Driven via _autoWalkMovingForwardThisFrame + _autoWalkTurnDirectionThisFrame
fields set in DriveServerAutoWalk and read in the MovementResult
construction at the bottom of Update. UpdatePlayerAnimation picks up
the localAnimCmd as the highest-priority animation source.
Walk/run threshold = 1.0m, retail-observed. ACE's wire-default of
15.0f is too generous; ACE's own physics layer uses 1.0f at
MovementParameters.cs:50 (with the 15.0f line commented out) and
Creature.cs:312 notes "default 15 distance seems too far". The
formula matches retail's MovementParameters::get_command at decomp
0x0052aa00: running = (initialDist - distance_to_object) >=
threshold, evaluated ONCE at chain start and held for the rest of
the auto-walk (matches retail "runs all the way / walks all the way"
behaviour). Wire-supplied threshold is ignored.
Pickup gate (IsPickupableTarget) now uses BF_STUCK
(acclient.h:6435, bit 0x4) to discriminate immovable scenery from
real pickup items that share a Misc ItemType. Sign (pwd=0x14 with
BF_STUCK) → blocked; spell component (pwd=0x10, no BF_STUCK) →
allowed. ACE's PutItemInContainer (Player_Inventory.cs:831-836)
responds with WeenieError.Stuck (0x29) on stuck items so the gate
prevents wasted wire packets + a UX dead-end.
R-key dispatch by target type. UseCurrentSelection's top-level
IsUseableTarget gate was wrong (blocked USEABLE_NO=1 items that
ARE pickupable). Reordered:
1. Creature → SendUse
2. Pickupable → SendPickUp
3. Useable → SendUse
4. Otherwise → "cannot be used" toast
Each handler keeps its own gate. Matches retail's per-action
server-side validation.
AP cadence revert (closes#74). With the MoveToChain race fixed,
the per-frame "send while moving" cadence is no longer load-bearing.
Reverted to retail's two-branch ShouldSendPositionEvent gate
(acclient_2013_pseudo_c.txt:700233-700285):
Interval NOT elapsed (< 1 sec): send if cell or contact-plane changed.
Interval elapsed (>= 1 sec): send if cell or position frame changed.
Adds _lastSentContactPlane field + ApproxPlaneEqual helper +
PlayerMovementController.ContactPlane public accessor. Extended
NotePositionSent(Vector3, uint, Plane, float) — both outbound sites
(MoveToState + AP) pass _playerController.ContactPlane.
Effective rates: 0 Hz idle, ~1 Hz smooth motion, per-event on
cell/plane changes, 0 Hz airborne.
CLAUDE.md updated with no-workarounds rule (commit `da126f9` on

Tests: build green; Core.Net 294/294; Core 1073/1081 (baseline,
8 pre-existing Physics failures unchanged). Visual-verified
end-to-end on 2026-05-16 for far/near Use + PickUp on NPCs,
doors, items, spell components, signs (correctly blocked), corpses,
turn-first animation, run/walk thresholds, idle quiet, smooth-
motion 1Hz.

Retail-anchored design for the missing visual feedback on selection:
four corner triangles + radar-blip colour coding around the selected
entity, drawn via ImGui in screen space.
Retail evidence (named decomp):
* VividTargetIndicator::SetSelected at 0x004f5ce0
* gmRadarUI::GetBlipColor at 0x004d76f0 (Portal / Vendor / Creature /
Player / PK / PKLite / Default colours from pwd._bitfield bits +
IsCreature/IsPlayer/IsPK predicates we already parse)
* VividTargetIndicator::CopyImage at 0x004f5dd0 (tints a source
bitmap by RGBA)
MVP scope:
1. RadarBlipColors helper (Core, with unit tests)
2. TargetIndicatorPanel (App, ImGui draw via background draw list)
3. Wire to existing _selectedGuid from B.4b
4. ~200 LOC + tests
Deferred to follow-ups: off-screen edge arrow, DAT-loaded sprite (MVP
draws procedurally), mesh-tint highlight, player-option toggle, server
selection-relay.
Pairs with #59 (WorldPicker over-pick): the indicator makes the
mis-pick visible, so the user can clear + reselect even before the
underlying picker is tightened.
Captured a live ACDREAM_PROBE_AUTOWALK trace double-clicking +Je from
~3.5m. Findings folded into the spec's State at design freeze section:
1. Wire parser is correct (matches ACE MoveToObject.Write +
MoveToParameters.Write byte-for-byte).
2. ACE sends mtRun=0.00. Not a parser bug — that's the wire value.
Retail's apply_run_to_command (0x00527BE0) fell back to the
player's own rate; our Slice 2 needs the same fallback chain.
3. Player position never changed during the entire trace — current
behavior is pure no-op on the inbound MoveToObject (literally
ignored, as our code at OnLiveMotionUpdated:3289 suggests).
4. ACE does NOT broadcast UpdatePosition for the local player during
auto-walk. Definitively kills Option C — nothing to blend with.
Local body must drive itself.
The trace validates the spec's Option A path. Slice 2 implementation
can proceed without further wire-format guessing.
Grounded the design in named-retail evidence. MovementManager::Perform
Movement at 0x00524440 case 6 (decomp lines 300628-300648) shows the
retail client's local-side dispatcher for inbound MoveToObject:
unpacks the wire, sets motion_interpreter->my_run_rate, calls
CPhysicsObj::MoveToObject on the LOCAL player's physics body. Same
code path retail used for every creature chasing the player.
Conclusion: Option A (run a local driver against the player's body)
is retail-faithful. Option C (server-position-blend) is a non-retail
shortcut and is now eliminated from consideration.
Re-scoped the spec into 4 slices:
1. ACDREAM_PROBE_AUTOWALK diagnostic baseline (~30 LOC)
2. PlayerMovementController.BeginServerAutoWalk + reuse of
RemoteMoveToDriver against the local player's body (~100 LOC)
3. Animation cycle selection during auto-walk (~20 LOC)
4. Local pickup-animation echo (closes#64, ~10 LOC)
Total ~160 LOC, no new files. All existing acdream infrastructure
(RemoteMoveToDriver, ServerControlledLocomotion, MotionState.MoveTo
Path parsing) is reused; the work is wiring it for _playerServerGuid
in addition to remote guids.
Captures the wire-format facts that are already parsed (MotionState.
IsServerControlledMoveTo + MoveToPath fields), the two gating sites
that drop the inbound MoveToObject for the local player today, and a
three-option solution space (run remote-driver locally, visual tween,
server-position-authoritative blend).
Recommendation: Option C first (smallest blast radius, single-commit
hotfix if ACE's UpdatePosition broadcast cadence is adequate); promote
to Option A only if the trace shows server broadcasts are too sparse
to render smoothly.
Explicitly does NOT implement yet. The 'walks then snaps back' visible
symptom is observed but the mechanism isn't characterized in detail —
the spec calls for a diagnostic-trace session first (ACDREAM_PROBE_
AUTOWALK env var, ~30 LOC) to capture exactly what ACE sends during a
failed auto-walk. The trace decides between Option C (sufficient
position broadcasts) and Option A (need to fill in per-tick locally).
#64 (local pickup animation) is flagged as likely-related — same
OnLiveMotionUpdated:3289 self-echo filter drops both. May fix in
the same B.6 work.
Phase B.4c closes#58 (filed during B.4b ship). When a door's
state flips via ACE Door.ActOnUse, the L.2g chain handles the
SetState collision-bit flip but no UpdateMotion handler ever
animated the door visually. Investigation traced the gap to the
spawn-time registration gate at GameWindow.cs:2692 which requires
a multi-frame idle cycle — doors have no idle.
Design: door-specific spawn-time branch that bypasses the gate,
builds an AnimationSequencer, seeds it with Off (closed) or On
(open) cycle based on spawn PhysicsState. ACE Door.cs:43 sets the
same initial state. ~40 LOC in one file. Reuses the existing
AnimationSequencer + per-frame tick + WB renderer pipeline. No
changes downstream.
Discovered during self-review that the per-frame tick at
GameWindow.cs:7691-7697 unconditionally overwrites ae.Entity.MeshRefs
with sequencer-derived transforms; an empty sequencer would collapse
the door to origin. The state-seeded SetCycle at spawn keeps the
sequencer always producing valid frames. Also documented:
ae.Animation = null is safe because the tick's sequencer branch at
line 7497 never reads it (only the legacy slerp else branch does).
Diagnostic tags renamed from phase-named [B.4c] to durable
[door-anim] / [door-cycle] per Opus reviewer feedback on B.4b.

Original spec placed WorldPicker in src/AcDream.App/Rendering/ and the
test in tests/AcDream.App.Tests/, but AcDream.App.Tests doesn't exist
as a project. Moved to AcDream.Core.Selection where it conceptually
belongs (no App-layer deps; only WorldEntity + System.Numerics) and
where the existing AcDream.Core.Tests project can hold the tests.

Phase B.4b closes the M1-blocker discovered during the L.2g slice 1
visual test: the input dispatcher fires SelectDblLeft on click but
GameWindow.OnInputAction has no case for any Select* / UseSelected
action, so clicks silently die.
Spec creates the minimum new structure to close the gap:
- New static helper WorldPicker (BuildRay + Pick over WorldEntities)
- Rename _selectedTargetGuid -> _selectedGuid on GameWindow (unifies
combat + interaction selection per retail's single-target model)
- Three switch cases (SelectLeft, SelectDblLeft, UseSelected)
Two further L.2g handoff inaccuracies surfaced during exploration:
WorldPicker and SelectionState do NOT exist in src/ (handoff and
ISSUES #57 both claimed they did). BuildPickUp also doesn't exist;
only BuildUse / BuildUseWithTarget / BuildTeleToLifestone are present.
Spec accounts for the actual state and defers BuildPickUp + SelectionState
class extraction.
Visual verification scenario reuses the L.2g slice 1 reproducibility
recipe: one Holtburg inn doorway log captures both L.2g + B.4b.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
L.2d slice 1.5 ship identified the Holtburg doorway blocker as a closed
Door entity (Setup 0x020019FF) whose PhysicsState.Ethereal bit flips
when the player Uses the door. The L.2d shape-fidelity work doesn't
cover this — the door's collision shape is correct; what's missing is
honoring the *runtime* state change.
L.2g is the new sub-phase that handles it. Scope is narrow:
* Parse inbound GameMessageSetState (0xF74B).
* Plumb the new PhysicsState value into ShadowObjectRegistry's
cached per-entity state so the existing CollisionExemption.IsExempt
already-in-place short-circuit sees up-to-date bits.
* Verify the Holtburg inn-door scenario: walk in blocked, Use door,
walk through, auto-close blocks again after 30s.
* Confirm UpdateMotion (NonCombat, On/Off) drives non-creature
entities (door swing animation).
Why a new L.2 sub-letter (and not B.4 or Door-special-case): the wire
mechanism (SetState flipping Ethereal) is also how ACE handles activated
traps, opened chests, spell projectiles becoming ethereal. Generic
infrastructure with doors as the verification scenario; lane is the
informal sixth "dynamic state."
Roadmap state:
* L.2 plan-of-record adds the L.2g section after L.2f.
* Milestones doc M1 phase list extended `a-f` -> `a-g`.
* CLAUDE.md status pointer + "next phase candidates" list updated to
name L.2g slice 1 implementation as the natural next step.
Risk: low. Wire-byte width has a hex-dump fallback path in slice 1
(holtburger says 12 bytes, ACE writes 16, capture settles it). ETHEREAL
plumbing already exists; we feed it new data. No resolver changes.

Reframes L.2d direction based on ACE BuildingObj.cs:39-52 + named-retail
acclient_2013_pseudo_c.txt:701260: retail's find_building_collisions is
one BSP test on PartArray.Parts[0]. No per-cell walkability. Per-cell
work (find_cell_list, point_in_cell, sphere/box_intersects_cell) is
L.2e territory.
Slice 1 is now a read-only BSP-hit diagnostic that captures full
collision evidence per L.2a [resolve] hit=yes line. Distinguishes 3
hypotheses (wrong BSP loaded / over-registered parts / BSPQuery flaw)
before any behavior change. Slice 2 is the actual fix, scoped from
slice 1's evidence.
Authors: brainstorm session 2026-05-13 (cold-start from L.2a slice
1+2+3 evidence). Predecessor handoff at

Two-slice phase:
- Slice A: ParticleHookSink applies CreateParticleHook.PartIndex via
SetupPartTransforms.Compute(setup.PlacementFrames). Closes#56.
- Slice B: drop EntityScriptActivator's ServerGuid==0 guard so
dat-hydrated EnvCell statics + exterior stabs fire DefaultScript.
Key reality discovery folded into the spec §3: EnvCell.StaticObjects
are already WorldEntities (via GameWindow.BuildInteriorEntitiesForStreaming),
so no synthetic-ID scheme + no new walker class needed — the handoff's
§4 Q1/Q2 options are mooted by entity.Id being collision-free.
Doc-drift fixes from C.1.5a folded into §8.

Visual verification at the Holtburg Town network portal passed for the
slice's mechanism: 10-hook portal script fires end-to-end with correct
color, persistence, orientation, and multi-emitter dispatch. After the
334f0c6 rotation-seed fix, the swirl is oriented correctly along the
portal's facing instead of world-NS.
Known limitation surfaced during verification and filed as issue #56:
ParticleHookSink ignores CreateParticleHook.PartIndex, so all 10 of the
portal's emitters collapse to the entity root position + identity-rotated
offset, producing a compressed and partly-ground-buried swirl instead of
the multi-tier shape retail renders. Mechanism is correct; per-part
transform handling is the next vfx-pipeline concern (will affect every
multi-emitter PES — slice 2 chimneys/fireplaces in particular).
Documentation changes:
- docs/ISSUES.md: new #56 entry with the captured entity guids
(0x7A9B405B / 0x7A9B4080), script ids (0x3300126D / 0x3300067A),
symptom data, root-cause hypothesis, file pointers, and acceptance
criterion. Notes the blocks-slice-2 relationship explicitly.
- docs/superpowers/specs/2026-05-12-phase-c1.5a-portals-design.md §9:
new limitation #1 documenting the verified PartIndex collapse symptom.
- docs/plans/2026-04-11-roadmap.md: new "C.1.5a" row in the shipped
table referencing the spec, plan, and #56 caveat.

Plan: docs/superpowers/plans/2026-05-12-phase-c1.5a-portals.md. Four
tasks, TDD-style, each task is a single commit boundary:
1. EntityScriptActivator class + three xUnit tests
2. Wire into GpuWorldState (new optional ctor param + two ?. calls)
3. Construct in GameWindow with resolver lambda
4. Visual verification at Holtburg Town network portal + roadmap update
Spec amendments correct an inaccuracy in the 2026-05-12 commit
(06d7fbd): the activator's call sites live in GpuWorldState
(AppendLiveEntity / RemoveEntityByServerGuid), not directly in
GameWindow as the original spec described. Also fixes the test file
path: tests/AcDream.Core.Tests/... not AcDream.App.Tests/... per the
existing test-project convention. No design changes — same activator,
same trigger condition, same lifecycle ordering.

Slice 1 of Phase C.1.5: fire Setup.DefaultScript through the already-
shipped PhysicsScriptRunner on server-spawned WorldEntity create, so
portals (and any other entity with a DefaultScript) emit their retail-
faithful persistent particle effects at spawn time. Reuses the C.1
runner-sink-system-renderer chain end-to-end; one new ~50-line class
(EntityScriptActivator) plus a two-line wiring in GameWindow.
Slice 2 (C.1.5b) will cover EnvCell.StaticObjects + animation-hook
verification; spec landed separately after slice 1 verification passes.
Acceptance: visual confirmation at the Holtburg Town network portal,
side-by-side with retail.

Final code review of slice 1 flagged one Important issue (the spec's
"zero cost when off" claim for the surface-dump path is technically
violated — _uploadMetadata always writes one dict entry per upload
regardless of env var) plus minor doc/consistency gaps. Applied:
1. Spec §5 "Cost when off": dropped the "Zero" claim; replaced with
"Negligible — one Dictionary write per upload (~30-50 KB at Holtburg)
plus a hash-table write per upload. Expensive work (file I/O,
histogram construction) is still env-gated." This matches reality.
2. Baseline doc §5: rewrote from "Raw logs (scratch, can be deleted)"
referencing files that were never preserved in this worktree, to
"Reproducing the measurements" with the actual PowerShell launch
commands. Honest about the raw logs not being kept; the captured
medians in section 2 are the canonical record.
3. New issue #55 filed in docs/ISSUES.md — static-entity slow path
reports ~1.45M meshMissing/5s at r4 standstill, drops to ~0 when
walking. LOW severity (no visible regression), hypothesis points
at a "permanently-missing entity gets re-classified every frame"
pattern that Tier 1 cache doesn't cover.
4. Roadmap shipped table: renamed "N.6.1" row to "N.6 slice 1" to
match every other artifact's naming. Search-discoverability fix.
None of these change the slice's conclusion or next-phase
recommendation (C.1.5 first, then reduced-scope slice 2).

Brainstormed design for the first slice of Phase N.6 (perf polish).
Slice 1 ships two commits: (1) fix the GPU timing query double-buffering
in WbDrawDispatcher (cross-vendor ring of 3, read-before-overwrite),
(2) add an env-gated surface-format histogram dump + capture the
radius=12 perf baseline at Holtburg. Slice 2 (TextureCache cleanup +
shader migration + optional persistent-mapped buffers) is deferred
until after C.1.5 (PES emitter wiring), with the next-phase decision
to be made on the baseline numbers slice 1 produces.

Post-A.5 polish Priority 3. EntityClassificationCache keyed by
(entityId, landblockHint) tuple. Entity dispatcher cpu_us median ~1.2 ms,
p95 ~1.5 ms — ~66% reduction vs pre-Tier-1 baseline. Closes the
post-A.5 polish phase entirely (#52, #54, #53 all closed).
See docs/ISSUES.md #53 closure + memory/project_tier1_cache.md for the
24-commit chain, 4 bug-fix iterations, and the per-tuple-vs-per-entity
recurring trap pattern documented for future cache work.
Captures Phase M (Network Stack Conformance) as a fully-formed phase
ready to be picked up later. Three deliverables:
1. Design spec at docs/superpowers/specs/2026-05-10-phase-m-network-stack-design.md
(~700 lines, 8 sections):
- Bar C completeness target ("wireable on demand"): every wire opcode
a 2013 EoR retail client receives or sends gets a parser/builder +
golden-vector test + typed event in the new layered stack.
- Three-layer architecture: INetTransport / IReliableSession /
IGameProtocol, with WorldSession as a thin behavior consumer.
Concrete C# interface signatures, sub-component decomposition.
- Worktree-branch big-bang migration on claude/phase-m-network-stack;
weekly rebase cadence; single --no-ff merge ships the phase.
- Per-sub-phase entry/exit gates, conformance test plan (golden vectors
+ live capture replay + live ACE smoke), 10-row risk register, scope-
cut order if calendar compresses.
- Cost: 256 hours / ~6.4 weeks single-developer; 4-6 weeks calendar
with subagent parallelization on M.1 + M.6.
2. Opcode coverage matrix at docs/research/2026-05-10-phase-m-opcode-matrix.md
(~284 rows across 5 sections):
- Section 1: 22 transport flags (14 implemented).
- Section 2: 12 optional-header fields (10 partial).
- Section 3: 51 top-level GameMessages (21 implemented).
- Section 4: 103 GameEvent sub-opcodes inside 0xF7B0 (27 parsed,
26 wired).
- Section 5: 96 GameAction sub-opcodes inside 0xF7B1 (24 built,
8 with live callers).
- Roll-up: ~34% complete by raw opcode count. Biggest single
unblocking step is wiring the 16 dead builders in section 5
(Phase B.4 surface — Use / UseWithTarget / Allegiance / Inventory
/ Social / Cast / Appraise).
- Sources cited per row: holtburger (629695a), ACE, named retail
decomp, acdream current state.
- Produced by 4 parallel research agents (one per class). Spot-check
pass owed before M.1 closes.
3. Roadmap update: Phase M section trimmed to summary + status + pointer
to the spec; the previously-tracked M.0 Tier 1 quick-wins are folded
into M.3 / M.4 / M.6 per the spec; M.1 retained as the matrix
construction sub-lane with status note.
Why this shape: the user goal is a complete, layered, testable network
stack that can be wired in as gameplay phases need it — independent of
whether each opcode is yet hooked to game state. The matrix is the
source of truth for "done"; the spec is the architecture the matrix
implements against; the roadmap is the index that points at both.
Decisions captured during the design discussion (in case they need
revisiting):
- Bar C ("wireable on demand") chosen over Bar A (holtburger parity)
or Bar B (named-retail completeness).
- Three layers (INetTransport / IReliableSession / IGameProtocol)
chosen over holtburger's two-layer split.
- Big-bang on a feature branch (worktree) chosen over strangler
pattern; preserves live-ACE testing on main throughout the phase.

The audit at docs/research/2026-05-10-tier1-mutation-audit.md enumerates
every entity.MeshRefs write site (5 STATIC at hydration, 1 DYNAMIC at
GameWindow.cs:7580 inside TickAnimations) and verifies that all 7
Position/Rotation write sites only touch entities in _animatedEntities.
Establishes the load-bearing invariant: an entity's renderer state is
stable from spawn to despawn iff entity.Id is NOT in _animatedEntities.
The spec at docs/superpowers/specs/2026-05-10-issue-53-tier1-cache-design.md
locks in the design from brainstorming on 2026-05-10:
- Static-only cache + DEBUG cross-check (option c) — catches future
regressions of the prior bug class without paying perf cost in Release
- Separate EntityClassificationCache class injected into WbDrawDispatcher
- Cache the rest pose, not the full model matrix (Position/Rotation read
live each frame so Release stays correct even if the invariant breaks)
- Pre-flatten Setup multi-parts at populate time (the bulk of the win)
- 15 new tests covering all invalidation paths + DEBUG cross-check +
Setup pre-flatten + lifecycle pin
Closes the audit + design steps of the post-A.5 polish Priority 3 work.
Implementation plan owned by superpowers:writing-plans next.
