Canonical handoff (research note) for the U.4c flap fix + the three residuals the
visual gate revealed (#78 terrain-not-gated-inside, camera-collision need, U.5).
Records the full hypothesis journey (H1/H2 both evidence-disproven) so the next
session doesn't re-walk them. ISSUES.md: flap recorded in Recently-closed; #78
annotated (more visible post-fix). CLAUDE.md: U-phase orientation updated with the
flap-fixed status + the canonical handoff pointer + camera-collision-next.

Decision (2026-05-30, with user): the WB-inherited two-pipe (inside/outside) render
split is the root cause of the indoor seam bugs (flap, missing/transparent walls,
terrain bleed) and cannot be seamless. Abandon A8/A8.F (#103); build ONE unified
pipeline driven by retail's PView portal visibility — seamless by construction. The
2026-05-30 camera-collision + physics viewer-cap work is kept (retail-faithful, but a
detour from the seam fix). New Phase U scoped; #103 superseded; CLAUDE.md / roadmap /
milestones updated; full decision + scope + next-session pickup prompt in
docs/research/2026-05-30-unified-render-pipeline-decision-and-handoff.md.

Session-end documentation for the issue #100 ship and the visibility-
culling investigation handoff for the next session.
Three documents land together:
- docs/superpowers/plans/2026-05-25-issue-100-terrain-cutout.md
(the 3-task plan that drove this session's f48c74a / a64e6f2 /
84e3b72 — never committed by Tasks 1-2)
- docs/research/2026-05-25-issue-100-terrain-cutout-handoff.md
(the predecessor session's smoking-gun research that drove the
#100 fix — never committed by the prior session)
- docs/research/2026-05-25-issue-100-shipped-and-culling-handoff.md
(THIS session's handoff: what shipped, what visual-verification
surfaced, the issue family map for #78 + #95 + the new cellar-
stairs finding, root-cause hypothesis, retail anchors, WB
references, do-not-retry list, and pickup prompt for the next
session's investigation + plan + implementation)
Plus two updates to existing files:
- CLAUDE.md — adds a ship paragraph for #100 to the M1.5 progress
block. References the new handoff doc as the next-session pickup
point.
- docs/ISSUES.md #78 — broadens scope from "outdoor stabs visible
through floor" to "outdoor stabs + terrain mesh visible inside
EnvCells". Adds the 2026-05-25 cellar-stairs evidence (per user
direction: not filed as new issue; treated as evidence
reinforcing #78's hypothesis #2). Promotes hypothesis #2 to
"high confidence as of 2026-05-25" and adds the retail anchor
(acclient_2013_pseudo_c.txt:311397 CEnvCell::find_visible_child_cell).
Acceptance criteria broadened to include the cellar-stairs case.
Next session: pickup prompt at the bottom of the new handoff doc
drives a /investigate → writing-plans → subagent-driven-development
pass on indoor-cell visibility culling — the work that closes#78
+ cellar-stairs together, and possibly #95 if the infrastructure
overlaps.

Records the A6.P8 mesh-aabb-fallback suppression ship outcome
in CLAUDE.md and moves issue #101 to Recently closed. Visual
verification confirmed end-to-end ramp climb on GfxObj 0x01000C16's
BSP (walkable inclined polygon, Normal.Z=0.717).

Records what landed in 3253d84 + what still needs visual verification.
Notes that the swept-sphere framing in the handoff was wrong and the
fix is a one-line ordering matching retail's actual code.

Today's evening session ran from "harness still doesn't reproduce the
cap" → "harness reproduces it" → "wait, the cap is only a symptom, the
real cause is upstream Z drift from the contact plane never refreshing."
The breakthrough question, from the user: "we know how retail OPENs it
from above, how hard can it be to know how to open it from below?" —
which reframed the investigation away from cap-event mechanics (where
six prior attempts looked) and toward "what about our STATE is wrong
when the player is in the cellar but not on the ramp?"
The math: player at cap is 10 m away from the cellar ramp in cell-local
X, but body.ContactPlane is still the ramp's slope plane. AdjustOffset
projects forward motion along that stale slope every tick, lifting Z
by +0.201 m per tick. After enough ticks of horizontal walking, the
head sphere reaches Z=94 and bumps the cottage floor. If the contact
plane refreshed to the flat cellar floor when the player walked off
the ramp, the drift would be zero, the cap would never be reachable.
Next session's task (per the pickup prompt at the bottom of the
findings doc): (1) verify the hypothesis chronologically against the
live capture, (2) find the walkable-refresh gap in
Transition.FindEnvCollisions / SpherePath.SetWalkable, (3) cross-ref
retail's CObjCell::find_env_collisions for the per-tick contact-plane
refresh logic.

The findings doc gets an evening-v2 follow-on documenting:
- GfxObj dump infrastructure shipped (cc3afbc)
- Harness reproduces cap-event collision normal (97fec19)
- Residual +0.0266m X-motion divergence — the new investigation target
- Pre-existing test suite flakiness (out of scope, tracked separately)
CLAUDE.md's "Current A6 phase" block points at the residual divergence
as the next concrete move with the test that gives <1s feedback per fix
attempt.

Adds the "Evening extension v2" paragraph documenting the apparatus
ship + root cause identification from the 2026-05-23 PM-late session.
The block names:
- The four commits that landed (fb5fba6 → 44614ab → 0f2db62 → f29c9d5)
- The apparatus: PhysicsResolveCapture + LiveCompare_* tests
- The root cause: cottage GfxObj 0xA9B47900 (landblock-baked static
building) blocks the head sphere at world Z=94.0 with cn=(0,0,-1)
- User's confirming observation about jumping (rules out step-up
hypotheses)
- The cap geometry math (foot Z=92.74 + sphereHeight 1.20)
- Documents-the-bug pattern for the first-cap test
- Test baseline (1178 + 8 serial)
- Pointer to the new findings doc as canonical pickup
- Concrete next-session move (extract cottage GfxObj polygons)

Apparatus only — no fix attempt. Per the systematic-debugging skill's
"3+ failures = question architecture" rule, the 6 hypotheses we
tested speculatively on the harness's airborne-at-tick-1 bug all
failed because we kept guessing what state the harness lacks. This
commit ships the evidence-driven path: capture the EXACT player
ResolveWithTransition call (every input + body-before + body-after +
result) into a JSON Lines fixture, then a comparison test loads the
fixture and replays it against the test engine. The first per-field
divergence pinpoints the missing apparatus state — no more guessing.
Adds:
- src/AcDream.Core/Physics/PhysicsResolveCapture.cs — new static module
with CapturePath (env var ACDREAM_CAPTURE_RESOLVE), PhysicsBodySnapshot
record, JSON Lines writer (thread-safe, flushes per record), process-
exit hook for clean shutdown.
- PhysicsEngine.ResolveWithTransition probe wiring: snapshot body at
method entry, snapshot again before return, refactor the two returns
into one path so the capture call site is single. Filtered to
IsPlayer mover flag so NPC/remote DR calls don't pollute.
- CellarUpTrajectoryReplayTests.cs:
• Capture_WritesJsonLinesRecordsWhenIsPlayerAndEnabled — drives 3
ticks with capture on, reads file back, verifies round-trip of
inputs + body-before/after snapshots.
• Capture_SkipsNonPlayerCalls — drives 3 NPC-style ticks (no
IsPlayer flag), confirms the file is not created.
Off by default. Set ACDREAM_CAPTURE_RESOLVE=<path> to a writable file
path; capture starts on the next player ResolveWithTransition call.
Test baseline: 1172 + 8 pre-existing failures + 2 new smoke tests
that pass = 1174 + 8. Verified by stashed-baseline comparison.

Adds the canonical pickup document
docs/research/2026-05-23-a6-p3-issue98-harness-handoff.md with:
- TL;DR + session arc (10 commits chronological)
- What the trajectory replay harness IS (committed apparatus)
- Bug 1 status: #98 cellar-up freeze (unfixed, 6 fix shapes failed)
- Bug 2 status: airborne-at-tick-1 (new, 6 hypotheses tested, root
cause not isolated)
- Exclusion list: DO NOT retry any of the 6+6 dead ends
- Apparatus inventory: probes, tests, fixtures, cdb captures
- Recommended next move: side-by-side comparison harness against
live PlayerMovementController state (evidence-first instead of
speculation-first)
- Alternative moves: pivot to other M1.5 issues or M2 prep
- Self-contained pickup prompt at the bottom of the handoff doc
Updates CLAUDE.md's "Current A6 phase" block to point at the new
handoff doc as the canonical resume artifact.
Updates ISSUES.md's #98 entry with the late-day extension findings,
the 6-hypothesis exclusion list, and a pointer to the handoff doc.
Test baseline maintained at 1172 + 8 pre-existing failures.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Updates ISSUES.md and CLAUDE.md to reflect the actual state of #98
after two days of work:
- The new [step-walk-adjust] probe (8a232a3) + capture + findings
(8daf7e7) prove AdjustOffset's slope projection is CORRECT. Sphere
Z climbs monotonically 90.95 -> 92.80 across the ramp at +0.045 m
mean zGain per call. The earlier "Fix targets 1-4" priority list
is OBSOLETE — AdjustOffset is not the bug.
- The climb caps at world Z ~= 92.80 because step-up's downward
step-down probe finds no walkable within stepDownHeight=0.6 m
below the proposed position. Cottage floor at Z=94 is ABOVE, not
below. 101 stepdown-reject hits in the capture vs 1 acceptance.
- Shape 1 fix attempted (0cb4c59): gated BSPQuery.AdjustSphereToPlane's
two SetContactPlane call sites by Normal.Z >= 0.99 to match retail's
cdb-observed flat-CP-only pattern. Reverted (402ec10) — gate broke
OnWalkable tracking. 74% of new capture in falling state. User
report: "can't get up the first step, jumped, stuck in falling
animation." Either retail synthesizes a flat CP from sloped
contacts (step_sphere_down:321203 path, unclear from BN decomp)
or our OnWalkable tracking is over-coupled to ContactPlaneValid.
Apparatus state: probe, findings, replay harness, plan, retail
cdb capture all committed and ready for next session.
Honest next-session moves (in order):
1. Build deterministic trajectory replay harness — 200ms inner loop
instead of 5-minute live test. Issue98 cell fixtures are half of
this already.
2. Pivot to less-coupled M1.5 issue while #98 awaits the harness.
3. Deeper named-decomp research on CEnvCell::find_env_collisions ->
BSPTREE::find_collisions indoor CP-setting chain. Prior passes
worked on the outdoor CLandCell path; indoor was never traced.
NO further #98 fix attempts until apparatus or research has
converged. Five+ failed attempts in the saga is the signal.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Final step of the apparatus plan. Updates ISSUES.md issue #98 and
CLAUDE.md's M1.5 status to reflect:
- The apparatus completed (Steps 1-5 land in commits 35b37df →
28c282a).
- The real divergence: retail's sphere is at world Z ≈ 94.48 (resting
on cottage floor) when find_walkable accepts; acdream's failing-
frame sphere is 2.47m lower at world Z ≈ 92.01.
- The four fix targets, in priority order. Fix plan is the NEXT plan,
scoped to Target 1 (step-up + ramp climb Z gain) or Target 2
(cottage-cell sphere reference).
- The replay harness (Issue98CellarUpReplayTests) is the test loop —
any fix that doesn't change the failing assertions is not the fix.
Today's commit graph on top of slice 5 (cf3deff):
35b37df triage — revert neg-poly + bldg-check experiments
f62a873 Step 2 — cell-dump probe + roundtrip test
3f56915 Step 2 capture — 3 real-geometry cell fixtures
856aa78 Step 3 — deterministic replay harness (7 tests)
6f666c1 Step 4 — retail cdb find_walkable capture script
28c282a Step 5 — replay vs retail divergence comparison
(this) Step 6 — ISSUES.md + CLAUDE.md handoff
Test baseline: 1167 + 8 (8 pre-existing failures, +19 new passing
tests across the apparatus). Build green throughout.
A6.P3 #98 is now in evidence-driven mode. Fix plan starts from the
divergence doc at
docs/research/2026-05-23-a6-p3-issue98-replay-comparison.md.
Pickup prompt for the fix-plan session is in §"Pickup prompt for the
fix plan" of that doc.
Slice 3 v2 (3e140cf) added point-in cell-stickiness in
ResolveCellId's indoor branch. User verification + slice3v2 capture
confirms: cell-resolver ping-pong is FULLY CLOSED.
Data:
- scen2_v2 capture (pre-slice-3): 20+ cell-transit events with
rampant ping-pong (0xA9B4014B ↔ 0xA9B4014A ↔ 0xA9B4013F at the
cellar boundary, Z stable ~96.4 — same tick re-classification)
- slice3v2 capture (post-fix): 1 cell-transit event (login teleport
only) — ping-pong fully eliminated
Findings:
- A6.P2 Finding 3 (cell-resolver sling-out family) CLOSED.
- Issue #90 (sphere-overlap stickiness workaround in same function)
now redundant; can be removed in A6.P4 after broader visual
verification.
- Issue #97 (phantom collisions + fall-through on 2nd floor) hypothesis
pending: same instability family, likely closed as side-effect of
this fix. Re-test on next happy-test session.
- Issue #98 (cellar-up stuck) PERSISTS but with NEW DIAGNOSIS.
Originally filed as cell-resolver ping-pong (which was true and now
fixed), but user verification shows the cellar-up symptom remains
with a DIFFERENT root cause: BSP step-physics at the cellar stair
TOP. Push-back trace from slice3v2 capture:
n=(0, -0.719, 0.695) sloped face (walkable per FloorZ=0.664)
delta=(0, 0, 0.75) step-down probe lifts sphere by 0.75m
winterp=1.0->0.0 entire walk-interp consumed per tick
Player progresses up most of the stairs but blocks at top step
where the cellar transitions to the cottage main floor. #98 issue
updated with this re-diagnosis.
Includes:
- scen4_cottage_cellar_slice3 acdream.log (slice 3 v1 evidence;
ping-pong already closed by v1's sphere-overlap stickiness, but
v1 over-corrected by holding player in cellar during legitimate
transitions)
- scen4_cottage_cellar_slice3v2 acdream.log (slice 3 v2 evidence;
point-in stickiness fixes the over-correction; cellar-up reveals
the deeper BSP step-physics bug)
Docs updated:
- ISSUES.md — #98 re-diagnosed
- docs/plans/2026-04-11-roadmap.md — A6.P3 slice 3 marked SHIPPED;
slice 4 (or A6.P4) scoped for #98 step-physics investigation
- CLAUDE.md — Currently-working-toward block updated
Test suite: 1148 pass + 8 pre-existing fail (baseline maintained).

Slice 2 v1 (`892019b`) attempted to close issue #96 by removing the
PhysicsEngine.cs L622 per-tick CP seed. v1 build/test green, CP-write
count dropped 91% in scen3 re-capture, BUT user happy-test surfaced
a regression: BSP step_up at the last step of stairs failed because
sub-step 1's AdjustOffset had no ContactPlane to compute the lift
direction.
Slice 2 v2 (`f8d669b`) reverted the seed removal + added a no-op-if-
unchanged guard inside CollisionInfo.SetContactPlane. The guard
early-returns when called with values matching current ci state.
Outcome:
- #96 PARTIALLY ADDRESSED, scope updated in ISSUES.md to "accepted as
documented retail divergence." The seed is load-bearing for step_up;
closing #96 fully would require deeper refactor (AdjustOffset
fallback to body.ContactPlane). Guard is benign improvement.
- Slice 2 v2 verification capture (scen3_inn_2nd_floor_slice2v2/
acdream.log) committed as evidence — 226,464 cp-writes from L624
seed confirms guard doesn't trigger for fresh-ci-per-tick pattern.
- Slice 2 v1 verification capture (scen3_inn_2nd_floor_slice2/
acdream.log) also committed — confirms v1 actually reduced cp-writes
(2,690 total) but the step_up regression made it unshippable.
NEW M1.5 BLOCKER FILED — issue #98: cellar ascent stuck at last step.
Evidence in slice2v2 capture's cell-transit chain:
0xA9B4014B → 0xA9B4014A → 0xA9B4013F → 0xA9B4014A → 0xA9B4014B → ...
(Z stable ~96.4; CellId ping-pongs every tick)
This is Finding 3 family (cell-resolver hysteresis missing) — same
root cause as #90 workaround + scen4 sling-out. Retail oracle:
CObjCell::find_cell_list Position-variant at
acclient_2013_pseudo_c.txt:308742-308783.
NEXT — A6.P3 slice 3:
- Port retail's cell-array hysteresis into ResolveCellId +
CheckBuildingTransit.
- Closes#98 (cellar-up), possibly #97 (phantom collisions same
instability family), enables #90 workaround removal.
Documents updated:
- ISSUES.md — #96 scope updated, #98 filed
- docs/plans/2026-04-11-roadmap.md — A6.P3 slice 2 marked SHIPPED,
slice 3 scope added
- CLAUDE.md — Currently-working-toward block updated to slice 3
Test suite: 1148 pass + 8 pre-existing fail (baseline maintained).

A6.P1 (cdb probe spike) + A6.P2 (analysis report) both SHIPPED this
session. Updated:
docs/plans/2026-04-11-roadmap.md — M1.5 phase block now shows A6.P1
+ A6.P2 SHIPPED with commit refs; A6.P3 entry expanded with the
Finding-2-first sequencing recommendation from A6.P2; A6.P4 entry
notes the original "Holtburg Sewer end-to-end" acceptance walk is
unreachable (sewer doesn't exist).
docs/plans/2026-05-12-milestones.md — M1.5 demo scenario split into
building/cellar half (achievable post-A6.P3) + dungeon half (blocked
on issue #95 visibility blowup; promote to post-M1.5 if #95 isn't
fixed in scope). Issue list updated: added #95 + indoor sling-out
(new from scen4); marked stairs/2nd-floor/cellar as characterized by
A6.P2 Finding 2 family.
CLAUDE.md — Currently-working-toward block now points at A6.P3 as
the active phase. A6.P1 + A6.P2 ship noted with the findings doc
pointer. Demo-scenario note updated to reflect the sewer + #95
reality. Issues-in-scope updated.
Also includes a 1-line trailing-prompt addition to scen3 + scen4
retail.log files (cdb wrote one more `0:000>` after the kill that
landed after the original capture commits).

ONE thing touches the DATs. WB code lives in our repo:
- src/AcDream.Core/Rendering/Wb/ — pure helpers (5 files, ~782 LOC)
- src/AcDream.App/Rendering/Wb/ — GL infra + mesh pipeline (~27 files, ~7K LOC)
Project references to WorldBuilder.Shared + Chorizite.OpenGLSDLBackend
dropped from AcDream.App.csproj and AcDream.Core.csproj.
references/WorldBuilder/ remains in-tree as read-reference only.
DefaultDatReaderWriter eliminated; DatCollection is the only dat reader.
WbMeshAdapter consumes our DatCollection via DatCollectionAdapter
(O-D7 fallback adapter; ObjectMeshManager has 26 _dats.X call sites,
exceeding the 20 refactor threshold).
Visual side-by-side passed: Holtburg town, inn interior, dungeon all
render identically to pre-O.
Doc updates:
- CLAUDE.md: rewrote WB integration cribs to point at extracted code.
Code Structure Rules rule 2 updated to remove stale seam names.
"Currently working toward" flipped from Phase O to M1.5 resumption.
- docs/architecture/worldbuilder-inventory.md: Phase O banner added.
Status/integration model updated to post-O ownership. Workflow
section updated to reference our extracted tree, not WB project ref.
- docs/plans/2026-04-11-roadmap.md: Phase O moved to shipped table.
Phase O "ahead" block collapsed to SHIPPED note. M1.5 block updated
to ACTIVE (Phase O shipped; resuming from 2026-05-20 baseline).
- docs/plans/2026-05-12-milestones.md: M1.5 heading updated to ACTIVE;
Phase O ship writeup prepended to the M1.5 block.
Phase O ship closes Tasks O-T1..O-T7 shipped across this session.

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.

Continued indoor testing through 2026-05-20 surfaced a deep family
of physics + lighting bugs that span buildings AND dungeons. Today's
session shipped 5 surgical fixes (A4 + #89 + #90 + #91 + #92) that
close the user-visible "walls walk through at Holtburg inn" symptom,
but #90 specifically is a CLAUDE.md-rules workaround (sphere-overlap
stickiness on top of point-only cell containment) added without prior
approval. The underlying issue (BSP push-back distance probably
diverges from retail) hasn't been measured. Plus the umbrella #83
(indoor multi-Z walking) has been open since 2026-05-19 with multiple
aborted fix attempts; plus indoor lighting (#80 + #81 + new #93 +
#94) has been deferred as "M7 polish" but is actually part of the
same indoor-experience problem.
Promoting to a milestone of its own forces the work to be central,
retail-anchored, and complete — not another whack-a-mole patch.
Milestone M1.5 — "Indoor world feels right":
Demo: enter Holtburg Sewer through the in-town portal, navigate
through 5-7 rooms with stairs + a multi-Z chamber, exit back to
town. Walls block. Stairs work. Items block. Lighting reads
correctly. Cell transitions smooth.
Phases:
A6 — Indoor physics fidelity (cdb-driven)
A7 — Indoor lighting fidelity (RenderDoc + retail-decomp driven)
Issues in scope: #80, #81, #83, #88, #90 (workaround removal),
#93 (new lighting umbrella), #94 (held-item spotlight),
+ TryFindIndoorWalkablePlane synthesis removal.
M2 ("Kill a drudge") deferred until M1.5 lands.
This commit updates:
- docs/plans/2026-05-12-milestones.md (M1.5 block inserted, M2 moved

- docs/plans/2026-04-11-roadmap.md (A6 + A7 sub-pieces detailed)

- docs/ISSUES.md (#80, #81, #83, #88, #90 tagged M1.5 scope;
new #93 indoor lighting umbrella + #94 held-item spotlight filed)
- docs/research/2026-05-21-open-items-pickup-prompt.md (landscape
table reorganized around M1.5 phases)
A6 + A7 specs to be drafted in the next session(s).

Phase A4 (multi-cell BSP iteration) ships in three commits (e6369e2,
493c5e5, 691493e — with revert 3add110 + reapply during visual
verification that proved A4 is not the cause of the issue surfaced).
1139 + 8 baseline maintained. 10 new unit tests pass. Wires retail's
CTransition::check_other_cells (acclient_2013_pseudo_c.txt:272717-272798)
into Transition.FindEnvCollisions.
Visual verification at the Holtburg inn vestibule surfaced a separate,
pre-existing M2 blocker (filed as #90): CellId ping-pongs between
outdoor 0xA9B40022 and indoor 0xA9B40164 on every wall push-back
because the push-back exits the indoor CellBSP volume, causing the
resolver to flip back to outdoor and bypass walls on outdoor ticks.
Indoor BSP results (Collided/Adjusted/Slid all firing) prove walls ARE
detected when the player is indoor; the aggregate "walls walk through"
appearance comes from CellId classification instability, not from
collision detection.
Bug reproduces fully with A4 reverted (launch-revert2.log captured 18
cell-id flips between 0xA9B40022 ↔ 0xA9B40164, 11 inside=True
building-transit events, 61 indoor-bsp queries firing the full
result distribution). A4 is correct and tested but dormant in
practice until #90 is fixed.

Closes ISSUES.md #87 + #85 + the remaining wall-pass-through portion of
#84 (fully closes#84). Portal-graph cell traversal replaces Phase D's
AABB containment. Walking through doors promotes/demotes CellId correctly
via portal traversal; walls block from inside indoor cells; indoor walkable
plane is synthesized from the cell's floor poly so the resolver tracks
walkability correctly during indoor movement.
Files two new issues: #88 (indoor static objects vibrate — pre-existing,
spotted during Phase 2 testing) and #89 (BSPQuery.SphereIntersectsCellBsp
— follow-up to make CheckBuildingTransit retail-faithful; currently uses
radius-less PointInsideCellBsp as a documented approximation).
ISSUES.md: #87, #85, #84 moved to DONE. #88 + #89 filed.
Roadmap: Indoor walking Phase 2 added to shipped table.
CLAUDE.md: recent-phase paragraph updated to reflect Phase 2 shipped.
New handoff: docs/research/2026-05-19-indoor-walking-phase2-shipped-handoff.md

Cluster A's investigation pinned #86 (picker) as structural and closed
it (Phase B). #84 and #85 both pinned on missing indoor cell tracking;
Phase D promoted CellId via AABB containment which un-stuck the
spawn-in-building case (closes#84 partially) but proved too tight for
threshold/doorway cells to keep CellId indoor during normal walking.
The proper fix is retail's portal-based cell traversal; filed as a
new ISSUES.md issue (see body) for the follow-up phase. Phase E
diagnostic infrastructure ([cell-cache] + extended [indoor-bsp]) stays
in place as scaffolding for that work.
ISSUES.md: #86 → Recently closed. #84 status updated to PARTIAL with
resolution paragraph. #85 status update note added. New issue #87 filed
for portal-based indoor cell tracking.
Roadmap: Cluster A added to Recently shipped with partial-ship note.
Forward entry added for the portal-traversal follow-up under Phase G.
CLAUDE.md: current-phase paragraph updated to reflect Cluster A partial
ship. Next phase deferred to Claude's choice in a future session.

Lifts 13 startup-time environment variables out of GameWindow.cs into a
single typed AcDream.App.RuntimeOptions record read once in Program.cs.
Behavior-preservation only — no live behavior change, no visual change.
Verified end-to-end against ACE on 127.0.0.1:9000: full M1 demo loop
(walk Holtburg, click door, click NPC, portal entry) plus DEVTOOLS
ImGui panels load cleanly.
Why: GameWindow.cs is 10,304 LOC and scattered Environment.GetEnvironmentVariable
calls were one of the structural smells called out in the new
"Code Structure Rules" doc. Typed options is the safest cut to make
first because the substitution is mechanical and parsing semantics
get pinned by unit tests.
What lands:
- CLAUDE.md: removed stale R1→R8 execution-phases line, replaced with
pointers to the milestones doc + strategic roadmap (the actual
source of truth). Tightened the "check ALL FOUR references"
section to describe WB as the production rendering base, not
just a reference. New "Code Structure Rules" section (6 rules)
captures the discipline we're committing to.
- docs/architecture/acdream-architecture.md: removed dangling link
to the deleted memory/project_ui_architecture.md.
- docs/architecture/code-structure.md (NEW, 376 LOC): rationale for
the 6 rules + 6-step extraction sequence
(RuntimeOptions → LiveSessionController → LiveEntityRuntime →
SelectionInteractionController → RenderFrameOrchestrator →
GameEntity aggregation). This PR is Step 1.
- src/AcDream.App/RuntimeOptions.cs (NEW, 100 LOC): typed record
with FromEnvironment(string) factory and Parse(datDir, env)
overload for testability. Covers ACDREAM_LIVE, _TEST_HOST/PORT/
USER/PASS, _DEVTOOLS, _DUMP_MOVE_TRUTH, _NO_AUDIO,
_ENABLE_SKY_PES, _HIDE_PART, _RETAIL_CLOSE_DEGRADES,
_DUMP_SCENERY_Z, _STREAM_RADIUS.
- src/AcDream.App/Program.cs: builds RuntimeOptions once, passes
to GameWindow.
- src/AcDream.App/Rendering/GameWindow.cs: ctor takes RuntimeOptions;
7 startup-cached env-var fields become expression-bodied
properties or direct _options.X reads; TryStartLiveSession,
audio init, legacy stream-radius branch all route through
_options.
- tests/AcDream.App.Tests/ (NEW project, 10 unit tests + csproj):
pins parser semantics — default-off bools, the literal "0"
gate for RETAIL_CLOSE_DEGRADES, the >=0 guard for
STREAM_RADIUS, null-vs-empty for user/pass, exact-"1" check
for diagnostic flags. Registered in AcDream.slnx.
Out of scope (per code-structure.md §4):
- Per-call-site ACDREAM_DUMP_* / _REMOTE_VEL_DIAG diagnostic reads
sprinkled through GameWindow (~40 sites). Rule 5 in CLAUDE.md
commits us to migrating these opportunistically as larger
extractions land, not in a bulk pass.
- AcDream.Core's project-reference to Chorizite.OpenGLSDLBackend.
Only the stateless .Lib namespace is used; tightening the project
reference is documented as future work in code-structure.md §2.
Build: green.
Tests: AcDream.App.Tests 10/10 ✓, Core.Net.Tests 294/294 ✓,
UI.Abstractions.Tests 419/419 ✓,
AcDream.Core.Tests 1073/1081 (8 pre-existing failures verified
against pre-refactor baseline by stash-and-rerun).
Visual verification: full M1 demo loop against ACE +Acdream login
including DEVTOOLS panel host load.
Next: Step 2 — extract LiveSessionController per code-structure.md §4.

M1 "Walkable + clickable world" landed 2026-05-16 with Phase B.6
(d640ed7). All four demo targets work end-to-end retail-faithfully:
walk Holtburg, open inn door, click NPC, pick up item.
Freeze list applied: L.2 (collision), B.4 (interaction outbound),
B.5 (pickup) — these phases are off-limits until M7 polish unless
something is actively broken.
CLAUDE.md "currently working toward" advanced to M2 — "Kill a drudge."
Phases to ship: F.2 (Inventory panel), F.3 (Combat math + damage),
F.5a (dev panels Attributes/Skills/Equipped/Inventory), L.1c
(combat animation wiring), L.1b (command router prereq).
Also removes the "record a demo video" requirement from milestone
discipline (CLAUDE.md rule #3 + milestones doc operating rule #3) —
user finds video recording pointless. Milestones are now textual
events: writeup + freeze flip + CLAUDE.md "currently working toward"
update. Saved as feedback memory.

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
the worktree branch). Saved as feedback memory at
memory/feedback_no_workarounds.md.
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.

Retires divergences flagged in the 2026-05-16 faithfulness audit:
1. AP cadence. Replaces the 1 Hz idle / 10 Hz active flat heartbeat
with a diff-driven model gated on `Contact && OnWalkable`
(acclient_2013_pseudo_c.txt:700327 SendPositionEvent). Sends on
position or cell change while grounded on walkable, plus a 1 sec
heartbeat; suppressed entirely airborne. PlayerMovementController
exposes `NotePositionSent(pos, cellId, now)` which GameWindow stamps
after each AutonomousPosition / MoveToState send — mirrors retail's
shared `last_sent_position_time` between SendPositionEvent
(0x006b4770) and SendMovementEvent (0x006b4680). Known divergence
from retail: ours is per-frame-while-moving, retail's effective rate
is ~1 Hz during smooth motion (cell/plane checks). Filed as #74,
blocked by #63 — when #63 lands we revert to retail's narrower gate.
2. Workaround retirement. Removes TinyMargin (0.05 m inside arrival)
and the AP-flush before re-send (`SendAutonomousPositionNow`). The
diff-driven cadence makes both obsolete. Close-range turn-first
deferred Use is kept (it IS retail — ACE Player_Move.cs:66-87
mirrors retail's CreateMoveToChain pre-callback rotation), renamed
`OnAutoWalkArrivedSendDeferredAction` to clarify it's a FIRST send.
`isRetryAfterArrival` parameter dropped.
3. Far-range Use/PickUp retry. Restored — was load-bearing, not the
"redundant cleanup" the Group 2 audit thought. Issue #63 means ACE
drops the first Use as too-far without re-polling on subsequent APs;
the arrival re-send is what makes far-range Use complete. Logs
include `(queued for arrival re-send pending #63)` to make this
explicit. Removes when #63 closes.
4. Screen-rect picker. New `AcDream.Core.Selection.ScreenProjection`
helper shared by `WorldPicker` and `TargetIndicatorPanel`. The
`Setup.SelectionSphere` projects to a screen-space square (retail
anchor `SmartBox::GetObjectBoundingBox` 0x00452e20); picker
hit-tests the mouse pixel against the same rect the indicator draws,
inflated by 8 px (`TriangleSize`). Guarantees what-you-see is
what-you-click — including rect corners that were dead zones under
the old ray-sphere picker. Per-type radius (1.0/1.6/2.0 m) and
vertical-offset (0.2/0.9/1.0/1.5 m) heuristic lambdas retired;
`IsTallSceneryGuid` deleted; `EntityHeightFor` trimmed to 1.5 m × scale
defensive default. No defensive sphere synth — entities without a
baked `SelectionSphere` are skipped, matching retail's
`GfxObjUnderSelectionRay` (0x0054c740).
5. Rotation rate run multiplier (Commit A precursor). `TurnRateFor(running)`
helper applies retail's `run_turn_factor = 1.5f` (PDB-named
0x007c8914) under HoldKey.Run, matching `apply_run_to_command` at
0x00527be0 (line 305098). Effective: walking ≈ 90°/s, running ≈ 135°/s.
Keyboard A/D + ApplyAutoWalkOverlay both use it.
6. Useability gate (Commit A precursor). `IsUseableTarget` corrected to
`useability != 0` per `ItemUses::IsUseable` at 256455 — ANY non-zero
passes (USEABLE_NO=1, USEABLE_CONTAINED=8, etc.), not just the
USEABLE_REMOTE bit. Cross-checked against 4 call sites in retail
(ItemHolder::UseObject 0x00588a80, DetermineUseResult 0x402697,
UsingItem 0x367638, disable-button-state 0x198826). Added
`ProbeUseabilityFallbackEnabled` diagnostic
(`ACDREAM_PROBE_USEABILITY_FALLBACK=1`) to measure how often the
creature/BF_DOOR fallback fires for ACE-seed-DB entities with
null useability.
CLAUDE.md updated with the graceful-shutdown rule for relaunch:
Stop-Process bypasses the logout packet, leaving ACE's session marked
logged-in for ~3+ min. CloseMainWindow() sends WM_CLOSE so the
shutdown hook runs and the logout packet reaches ACE.
Tests: +3 ScreenProjectionTests + 6 WorldPickerRectOverloadTests = +9.
Core.Net 294/294 pass; Core 1073/1081 (8 pre-existing Physics failures
unchanged). Visual-verified 2026-05-16: rotation rate, useability,
screen-rect click area, double-click + R-key + F-key Use/PickUp at
short and long range — dialogue/door/pickup fire on arrival.
Filed follow-ups #70 (triangle apex/size DAT sprite), #71 (picker
Stage B polygon refine), #72 (cdb omega.z probe), #73 (retail-message
sweep pattern), #74 (per-frame AP chattier than retail — blocked by
#63). Old ray-sphere `WorldPicker.Pick(origin, direction, ...)`
overload kept for back-compat; no callers in acdream proper.

Adds a 'MCP servers (live tooling)' section after the cdb retail debugger. Ghidra MCP (LaurieWired v1.4 HTTP) on :8081 serving patchmem.gpr provides live decomp lookups by address/name/xref without dumping acclient_2013_pseudo_c.txt into context. WireMCP (stdio, Node, tshark wrapper) enables loopback capture against 127.0.0.1:9000 for ACE wire-protocol cross-checks (0xF61C, 0xF74A, 0xF7DE parsing). Both extend the static-decomp + cdb workflow with live introspection.

Phase B.5 (ground-item pickup, close-range path) shipped and
visual-verified 2026-05-14 at Holtburg. M1 demo target 4/4 ("pick up
an item") met.
New ship-handoff doc captures the 5-commit history including the
post-visual-test PickupEvent (0xF74A) wire-handler fix that closes
the local-despawn gap.
Roadmap and CLAUDE.md updated to reflect the ship + the new follow-up
issues:
- #63 (MEDIUM) — server-initiated MoveToObject auto-walk not
honored; blocks double-click pickup + out-of-range F. Filed as
candidate Phase B.6. holtburger has the reference implementation.
- #64 (LOW) — local-player pickup animation does not render
(retail observers see it correctly). Likely a self-echo filter
dropping UpdateMotion(Pickup) on the local player.
Carry-overs from B.4c (#61 link-cycle flash, #62 PARTSDIAG null-guard)
unchanged.
L.2g slice 1 is CODE-COMPLETE: parser + registry mutator + WorldSession
dispatcher + GameWindow subscriber (4 commits: 2459f28, d538915,
536a608, 108e386). Build clean, 6 new tests pass, baseline-stable
across the full suite. Per-commit + final integration code reviews
all approved.
Visual verification deferred: while running the Holtburg-doorway test,
Phase B.4's outbound Use handler turned out to be unwired. The wire
builders (InteractRequests.BuildUse), classes (SelectionState,
WorldPicker), input-action enums, and keybindings all exist — but
GameWindow.OnInputAction has no case for SelectDblLeft, so the click
silently does nothing. The inbound L.2g chain we just landed can't
fire until something sends an outbound Use.
This commit captures the handoff + reframes next-session work:
* docs/research/2026-05-12-l2g-slice1-shipped-handoff.md (NEW)
Full evidence: 4 shipped commits, end-to-end code flow, B.4
discovery explanation, 4 minor + 1 Important review notes
(the Important one is a test-coverage gap that the B.4b visual
test will settle automatically), reproducibility recipe,
next-session pick.
* CLAUDE.md
"Currently in Phase L.2" paragraph: L.2g slice 1 code shipped;
visual test deferred to B.4b. Next-phase-candidates list:
L.2g slice 1 (now done) replaced with the B.4b candidate
pointing at the slice scope.
* docs/plans/2026-04-29-movement-collision-conformance.md
L.2g section gains a "Current shipped slice (2026-05-12):" table
listing the 4 commits.
* docs/plans/2026-05-12-milestones.md
M1 phase-list updated: L.2g slice 1 (code) shipped; B.4 renamed
"B.4 / B.4b" with the gap-discovery note + B.4b shape.
* docs/ISSUES.md
New issue #57 (HIGH) for the B.4 interaction-handler gap.
Promoted to Phase B.4b; will close as
DONE (promoted to Phase B.4b) when B.4b's design spec lands.
* Memory file project_interaction_pipeline.md (in personal
memory dir, not in this commit) updated to reflect reality.
Next session: Phase B.4b (~30-50 LOC, 1-2 subagent dispatches,
~30 min). Subscribe SelectDblLeft -> WorldPicker.Pick ->
InteractRequests.BuildUse -> _liveSession.SendGameMessage. Same
Holtburg-doorway visual test verifies both L.2g slice 1 and B.4b
in one pass.
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.

User request: stop being asked "which should we work on next?" Claude
should drive the work-order autonomously per the milestone discipline +
roadmap, never present a menu of options, never pause for confirmation
between phases.
Two additive edits:
1. New "Work-order autonomy — the meta-rule" paragraph in the Milestone
discipline section, placed above the four motivation rules. Names
it the meta-rule that makes the others actually work. The user
retains the right to redirect; default is "Claude drives, user
reviews." If two next steps are genuinely equivalent, state the
choice in one sentence and start — don't ask.
2. Strengthened the "Continue to the next planned sub-step" bullet in
"Things you should just do without asking" under How to operate.
Adds explicit "You pick what comes next per the Milestone discipline
section — never present the user a menu like 'should we do X or Y?'
or ask 'what next?'. Just choose and announce the choice in one
sentence."
Saved as durable feedback memory in feedback_work_order_autonomy.md
(outside repo, in Claude's auto-memory).
Triggered by the 2026-05-12 session where the user reported feeling
lost / jumping between things; the diagnosis was decision fatigue from
constant work-order picks. Milestones doc (ecb0f2d) gave the structure;
this commit makes Claude responsible for executing it.

Introduce a morale + scope-management layer above the roadmap. Seven
milestones (M0-M7) from "Connect & explore" to "v1.0", each defined by a
concrete playable scenario and ~6-10 weeks of work. Each milestone hit
triggers a recorded demo video + a freeze list of phases that go
off-limits until M7's polish pass.
M0 ("Connect & explore") is declared done retroactively — ~25 shipped
phases through 2026-05-12 (terrain, network, audio, particles, chat,
input, streaming, WB rendering migration, sky/lighting, particle system,
combat/spell/item data layers) are frozen. Currently working toward M1
("Walkable + clickable world"): L.2 collision + B.4 interaction, ~4-6
weeks.
CLAUDE.md gains a "Milestone discipline" section above the existing
"Roadmap discipline" — sets the two-altitude orientation (milestones
above, phases below), names M1 as the current target, and codifies the
four motivation rules: (1) one active milestone at a time, (2) frozen
phases off-limits, (3) recorded demo video per landing, (4) state both
altitudes at session start.
Addresses the "everything is half-built" feeling caused by per-phase
vertical-slice ships never adding up to a milestone-level "done" event.

Three new bullets, all evidence-driven from /insights:
"Only stop and wait for the user when":
- Request is an investigation/audit/analysis/review/report-only — no edits
or diagnostic drops until the user approves a fix. Use the /investigate
skill (local at .claude/skills/investigate/SKILL.md, gitignored).
- A referenced commit/path/branch/doc doesn't exist where the user said
it would — ask one short question; don't go hunting across branches.
Prevents the N.5-handoff-style 30-min wrong-branch exploration.
"What NOT to do":
- Don't replace working retail-faithful logic with a modern redesign
without explicit approval. Cites the 267 min remote-entity rewrite +
sky-fog shader speculation both reverted in full. Retail-faithful
first; "cleaner" second.
The /investigate skill itself stays local (option 3 — not committed).

Documents the L.2a-slice-1/2/3 ship for the next session and updates
the project's source-of-truth docs to reflect current state.
New files:
- docs/research/2026-05-12-l2a-shipped-l2d-handoff.md — full cold-start
handoff: what shipped, three findings (L.2e cell-id format gap, L.2c
wall-slide working, L.2d sub-direction = CBuildingObj port), branch
state, diagnostic surface inventory, files changed, open concerns,
cold-start checklist, reproduction recipe.
- docs/research/2026-05-12-l2d-next-session-prompt.md — terse copy-paste
prompt for the next Claude Code session.
Modified:
- docs/plans/2026-04-29-movement-collision-conformance.md — added "Current
sub-direction" note under L.2d capturing the evidence-driven call:
building-mesh fidelity issue, not door-state-toggle.
- CLAUDE.md — updated "Currently between phases" → "Currently in Phase
L.2"; added L.2a shipped paragraph; added ACDREAM_PROBE_RESOLVE /
ACDREAM_PROBE_CELL to Diagnostic env vars; prepended L.2d brainstorm
to next-phase candidates list.
No code changes in this commit.

Roadmap:
- Status header now reads "Between phases" with C.1.5b in the recent-wins
bullet list.
- New SHIPPED row in the table (C.1.5b) summarising both slices, the
reality discovery about EnvCell statics, and the 4 visual-verified sites.
- The "IN FLIGHT — C.1.5b" sub-bullet under Phase C flipped to SHIPPED.
ISSUES.md:
- #56 removed from Active.
- #56 added to Recently closed with full commit chain (1e3c33b spec+plan,
f3bc15e SetupPartTransforms helper, 11521f4 ParticleHookSink part-transform,
5ca5827 activator refactor, 8735c39 GpuWorldState fire-sites), resolution
notes, and the visual-verification record.
CLAUDE.md:
- "Currently in flight" pointer replaced by a "Currently between phases"
marker + a C.1.5b shipped paragraph that's parallel to the existing
C.1.5a entry.
- "After C.1.5b" → "Next phase candidates".
Visual verification 2026-05-12: portal swirl matches retail extent + lateral
spread (no ground-burial); Holtburg Inn fireplace flames; cottage chimney
smoke; spell-cast particles on +Acdream — all match retail.

EntityClassificationCache keyed by (entityId, landblockHint) tuple lands
per spec docs/superpowers/specs/2026-05-10-issue-53-tier1-cache-design.md
+ plan docs/superpowers/plans/2026-05-10-issue-53-tier1-cache.md.
Perf result (horizon-safe preset + High quality, AMD Radeon RX 9070 XT
@ 1440p): entity dispatcher cpu_us median ~1200 us, p95 ~1500 us. Down
from ~3500m / ~4000p95 pre-Tier-1. ~66% / ~63% reduction. Well under
the A.5 spec budget (median <= 2.0 ms, p95 <= 2.5 ms). No BUDGET_OVER
flag across 30s+ standstill captures.
Visual gate cleared after 4 bug-fix iterations:
- 71d0edc: namespace stab Ids globally (cross-LB id collision)
- 95ebbf3: key cache by (entityId, landblockHint) tuple (defensive)
- c55acdc: skip cache populate when classification is incomplete
- f928e66: incomplete-entity flag must persist across same-entity tuples
User-confirmed visually via +Acdream test character: NPCs animate,
multi-part static buildings render fully (no airborne geometry, no
Z-fighting, no missing parts, no wrong textures), Nullified Statue of
a Drudge on top of the Foundry renders all parts, trees outside
Holtburg render with branches present.
Closes the post-A.5 polish phase. Issues #52, #54, #53 all closed.
Tests: 1711 passing, 8 pre-existing physics/input failures unchanged.
N.5b sentinel: 112/112 throughout.
Memory: ~/.claude/projects/.../memory/project_tier1_cache.md +
feedback_cache_per_tuple_pattern.md capture the audit-gap and per-tuple-
vs-per-entity recurring trap for future cache work.

Document Phase N.5b shipping (terrain on the modern rendering path via
Path C — `TerrainModernRenderer` mirrors WB's `TerrainRenderManager`
pattern but consumes acdream's `LandblockMesh.Build` so retail's
`FSplitNESW` formula stays in lockstep with physics + visual mesh).
Changes:
- `docs/plans/2026-04-11-roadmap.md` — add N.5b row to the Shipped
table; promote N.5b's "Phases ahead" entry to ✓ SHIPPED with the
Path C resolution + perf reality check; refresh N.6 scope to note
Terrain has joined the modern path (legacy `Texture2D` retirement
scope narrows to Sky + Debug); update top-of-doc Status line.
- `docs/ISSUES.md` — close issue #51 (WB terrain-split formula
divergence). Move from OPEN to "Recently closed" with the Path C
resolution: never adopted WB's formula; modern dispatcher uses
retail's via `LandblockMesh.Build`. References `da56063` (the
black-terrain fix that landed within the N.5b ship chain).
- `CLAUDE.md` — add `TerrainModernRenderer.cs` to the WB integration
cribs list with the GL_INVALID_OPERATION caveat (use uvec2 +
`sampler2DArray(handle)` constructor, NOT direct
`uniform sampler2DArray` + `glProgramUniformHandleARB`). Update
the "Currently in flight" preamble: N.6 builds on N.5 + N.5b;
add an N.5b shipped paragraph linking the perf baseline doc.
- `docs/plans/2026-05-09-phase-n5b-perf-baseline.md` — new doc
capturing the radius=5 Holtburg perf measurement (modern 6.4-7.0
µs median vs legacy 1.5 µs — modern is ~4× SLOWER on CPU at
radius=5). Documents the spec acceptance criterion #5 amendment,
the architectural wins that DO hold (zero glBindTexture/frame,
constant-cost dispatch as A.5 raises radius, per-LB frustum cull),
and the three high-value gotchas surfaced during implementation.
User-memory updates (outside repo, not in this commit):
- `memory/project_phase_n5b_state.md` — full N.5b state file with
the three gotchas captured.
- `memory/MEMORY.md` — index entry pointing at the state file.
Build: dotnet build green. No code changes in this commit.

Reframe the selection-blink follow-up so it doesn't suggest near-term
work. Was listed in N.5 ship record as "Phase B.4 follow-up adds the
field" — now phrased as open backlog with the hook reserved in
mesh_modern.vert's InstanceData comment for whoever eventually picks
it up.
The shader hook itself is unchanged — change is purely doc wording in
the plan SHIP record + CLAUDE.md WB integration cribs.

Final cross-cutting review of N.5 found that Task 15's deletion of
mesh_instanced.vert/.frag left InstancedMeshRenderer orphaned —
ACDREAM_USE_WB_FOUNDATION=0 silently rendered terrain+sky only with
no entities. The SHIP commit's "[x] ACDREAM_USE_WB_FOUNDATION=0 still
works" claim was inaccurate.
Resolution: formal retirement of the legacy renderer path within N.5
instead of deferring to N.6.
Deleted:
- src/AcDream.App/Rendering/InstancedMeshRenderer.cs
- src/AcDream.App/Rendering/StaticMeshRenderer.cs
- src/AcDream.App/Rendering/Wb/WbFoundationFlag.cs
GameWindow simplified — capability detection is unconditional, missing
bindless throws NotSupportedException with a clear message at startup.
WbDrawDispatcher + mesh_modern shader load are mandatory after init.
No escape hatch.
GpuWorldState simplified — WbFoundationFlag.IsEnabled guards on
AddLandblock/RemoveLandblock removed; adapter calls are unconditional
when the adapter is non-null.
PendingSpawnIntegrationTests updated — WbFoundationFlag.ForTestsOnly_ForceEnable
static ctor removed (flag is gone; adapter calls are unconditional).
The ApplyLoadedTerrain physics-data loop was also simplified: the
EnsureUploaded sub-loop that fed InstancedMeshRenderer is gone;
_pendingCellMeshes is now explicitly cleared to prevent unbounded
accumulation (the worker thread still populates it, but WB handles
EnvCell geometry through its own pipeline).
Spec §2 Decision 5 + §10 Out-of-Scope updated. Plan ship-amendment
section added. Roadmap updated (N.5 ships with retirement; N.6 scope
narrowed to perf-only). CLAUDE.md "WB integration cribs" updated.
Perf baseline doc updated. WbDrawDispatcher class summary docstring
corrected to describe the as-shipped SSBO + multi-draw-indirect path.
ISSUES.md #51 updated (terrain not in N.5 scope; deferred to N.7).
Bindless support is now a hard requirement. Modern desktop GPUs
universally expose GL_ARB_bindless_texture + GL_ARB_shader_draw_parameters;
if a user hits the NotSupportedException, that's a real bug report
worth investigating, not a silent fallback.
Build: 0 errors, 0 warnings. Tests: 71/71 (Wb+MatrixComposition+TextureCacheBindless filter).

Moves N.5 from in-flight to Shipped (2026-05-08). N.6 (retire
InstancedMeshRenderer + perf polish) becomes the in-flight phase.
CLAUDE.md in-flight pointer updated to match.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Phase N.4 (Rendering Pipeline Foundation) ships. WbFoundationFlag
flips to default-on (== "1" → != "0"). WB's ObjectMeshManager is
now acdream's production mesh pipeline; WbDrawDispatcher is the
production draw path. Legacy InstancedMeshRenderer is retained as
ACDREAM_USE_WB_FOUNDATION=0 escape hatch until N.6 retires it.
Visual verification at Holtburg passed:
- Scenery (trees / rocks / fences / buildings) renders correctly
- Characters connected with full close-detail geometry (Issue #47
preserved — GfxObjDegradeResolver path intact)
- FPS substantially improved by grouped instanced draws + per-entity
AABB cull + opaque front-to-back sort + palette-hash memoization
Three high-value WB API gotchas surfaced during Task 26 visual
verification and are now documented in CLAUDE.md "WB integration
cribs" + plan Adjustments 7-9 + memory project_phase_n4_state.md:
1. ObjectMeshManager.IncrementRefCount only bumps a counter — does
NOT trigger mesh loading. Call PrepareMeshDataAsync explicitly.
2. ObjectRenderBatch.SurfaceId is unset — read batch.Key.SurfaceId.
3. Modern rendering (GL 4.3 + bindless = every modern GPU) packs
every mesh into ONE global VAO/VBO/IBO. Use
glDrawElementsInstancedBaseVertex(BaseInstance) with FirstIndex +
BaseVertex from the batch, not naive DrawElementsInstanced.
Plan doc flipped to Final state. Roadmap N.4 → Live ✓; N.5 rebranded
from "Terrain rendering" to "Modern rendering path" (bindless +
multi-draw indirect on top of N.4's foundation; terrain rendering
moves to N.5b). CLAUDE.md "Currently in flight" pointer updated to
N.5. New memory file project_phase_n4_state.md preserves the three
WB gotchas for cross-session continuity.
n4-verify*.log added to .gitignore.
