Stage 0's measurement (previous commit) says the projection is redundant,
so AD-10 retires by deletion rather than by narrowing.
The measurement. With the sample forced to null at BOTH fork sites, from a
clean build:
* a remote running 30 ticks down a 31-degree walkable ramp produces a
BIT-IDENTICAL trajectory, position for position;
* on an 8.4-degree ramp the two differ by at most 2.8e-5 m in Z after 30
ticks (0.03 mm) and are identical in X and Y — float ordering noise
from projecting twice against the same plane rather than once;
* the whole AcDream.Runtime.Tests suite is unchanged.
That is what redundancy looks like, and the arithmetic explains it. The
boundary projection and Transition.AdjustOffset are the same operation
(v -= N * dot(v, N)) against the same plane, and the composition is
idempotent: a vector already on the plane has dot(v, N) == 0, so the
sweep's own projection is a no-op on an already-projected offset and the
full-strength projection on an unprojected one. Either alone produces the
same offset. On terrain a THIRD mechanism, ValidateWalkable's push-out,
re-seats the sphere on the plane every sub-step regardless.
Deleted:
* both RuntimeRemotePhysicsUpdater sample sites (the host and no-host
fork branches carried the block verbatim — the AP-22 shape, a row
naming one site where two exist);
* the terrainNormal parameter and projection block on
RemoteMotionCombiner.ComposeOffset;
* the same block on ComputeOffset, which has no production callers but
held a second copy of the divergence, so leaving it would have made
the row's retirement false;
* PhysicsEngine.SampleTerrainNormal, now callerless.
Removing the parameter rather than passing null is deliberate: it is what
makes a future one-site-only regression a compile error instead of a
silent half-fix.
Two tests went with it —
ComputeOffset_RootMotionFallback_SlopedTerrainNormal_ProjectsZOntoSlope and
its flat-ground twin. Both were weak on their own terms: they drove the
production-dead ComputeOffset and computed their expected values by
re-implementing the projection formula, so they could catch a wrong
MULTIPLY but never a wrong PLANE — which is exactly what the divergence
was. The surviving coverage is geometric and runs the production tick.
Three claims in the old row did not survive contact with the code and are
recorded in the retired row rather than quietly dropped: the justification
(remotes do run the sweep); the description of ComposeOffset's guard as
"interpolation-active" when the code reads `if (!interpolationOverwrote`;
and the roof clause, stale since Bug B gated the sample on OnWalkable —
a steep roof is OnWalkable == false, so the path never ran on #32's
geometry. The retail anchor is corrected too: pc:272296-272346 truncated
both the sliding-normal validity gate at the head and the entire safety
push-out block at the tail. The whole function is 0x0050a370,
pc:272271-272393.
This does not fix #32 and does not partially fix it. #32's remote half was
already closed at

acdream documentation map
This page is the entry point for project documentation. It distinguishes current sources of truth from implementation history so an old plan or issue banner cannot silently override the current program state.
Current snapshot — 2026-07-27
- Milestone state: M3, “Cast a spell,” landed 2026-07-21. M4, “Live in the world,” is active.
- M4 gameplay program: resume the pre-M4 world-interaction completion program. Favorite-spell overflow, status Use/Assess, and the complete assessment surface are user-accepted. Equipped-child picking and vendor browse/transactions remain Slices 4–6.
- Structural/runtime state: all eight
GameWindowdecomposition slices, Modern Runtime Slices A–J, and the connected visual/lifecycle gates are complete.GameWindowis a 1,622-line composition/callback shell.AcDream.Runtime.GameRuntimeowns canonical session, entity/object, gameplay, movement, physics, projectile, environment, and portal state; graphical and no-window hosts borrow the same owner graph. - Headless state: Slice K is complete.
AcDream.Headlessis a presentation-free Windows/Linux host with deterministic commands/events, shared immutable content, multi-session isolation, reconnect, resource telemetry, and 1/5/10/30-session gates. The final two-account native-Linux soak completed ten minutes, logged out through ACE, and converged every ownership ledger. - Linux graphical state: Slice L0 and the L1 implementation checkpoint are
complete at
66f114b2and11501d52. Native Windows passes the active modern-GL/audio/window smoke. WSLg X11/Wayland correctly reject their missingGL_ARB_bindless_texture. Physical-Linux validation and L2–L6 are explicitly deferred; resume at the supported AMD/NVIDIA L1 gate. - Completed gameplay gates: R6 locomotion/collision/projectile/teleport/ radar, two-client portal-out/materialization, indoor prepared collision, loot ordering, local/remote ground drops, and selection-marker lifetime.
- Separate visual verification: issue
#225, the shared-alpha lifestone/particle result; its connected resource-lifetime and performance routes pass. - Carried behaviour debt: issue
#153(far teleport onto an unstreamed edge),#116(narrowed slide response),#235(capped/RDP jump cadence), and the active temporary-stopgap rows in the divergence register. - Divergence audit: 189 active rows — IA 18, AD 38, AP 91, TS 38, and UN 4 — plus retained struck/retired historical rows such as TS-37.
- Latest automated baseline: the Release build succeeds with the 17
test-project warnings tracked by issue
#228; 8,826 tests pass and five are intentionally skipped. App passes 3,763 / 3 skips. The L1 Windows supported smoke and WSLg X11/Wayland negative-capability reports all end with zero window/GL/input/audio ownership.
Sources of truth
Read these in this order when deciding what to do next:
plans/2026-05-12-milestones.md— the active playable outcome, freeze boundaries, and visual gates.plans/2026-04-11-roadmap.md— strategic phase ledger: shipped, active, deferred, and future work.ISSUES.md— tactical defects and small follow-ups. The status inside an issue is authoritative; physical order is not.architecture/retail-divergence-register.md— every known place runtime behavior can differ from retail.architecture/acdream-architecture.mdandarchitecture/code-structure.md— ownership, dependency, update-thread, and extraction rules.architecture/worldbuilder-inventory.md— rendering/DAT code already owned in-tree versus mechanisms still ours to port.
If these disagree, milestones control the current outcome, the roadmap controls work ordering, the issue status controls the individual defect, and the architecture documents control implementation shape. Reconcile the stale document in the same change; do not leave both claims standing.
Research and implementation records
research/named-retail/is the primary retail oracle: named pseudo-C, headers, symbols, and types from the Sept 2013 build.research/decompiled/is the older Ghidra fallback.research/contains focused pseudocode, traces, fixtures, and gate reports. A dated research note records evidence; it does not become a new roadmap.superpowers/specs/andsuperpowers/plans/are per-slice design and execution records. Completed plans remain historical.audit/contains completion and conformance audits.reference/ace-commands.mdpreserves the local ACE server's complete in-game command catalog and points to the authoritative per-command help surface.
Durable memory
../claude-memory/MEMORY.mdindexes the live subsystem memories and the render/physics digests. Read a domain digest before changing that subsystem, especially its DO-NOT-RETRY table.../memory/contains stable engineering references such as the modern rendering pipeline, two-tier streaming, and toolchain notes.
Memory accelerates recall; it does not outrank the canonical documents above. When current truth changes, update the relevant canonical document and distill only the durable lesson into memory.
Historical and deprecated documents
bugs.mdis the April 2026 bug snapshot. It is preserved for archaeology and is not an active ledger.- Dated plans and specs describe the decision at that time. Their completion wording is historical unless the current milestone/roadmap explicitly links the item as active.
- Old
R1→R8architecture sequencing is superseded. Current execution comes from the milestones and strategic roadmap.
Documentation maintenance rules
- Update milestone, roadmap, issue, divergence, architecture, and memory claims in the same commit when a shipped change affects them.
- Keep one issue ID per defect. Narrow an issue in place; do not reuse another issue's number as a shorthand.
- Mark automated, connected, and visual gates separately. An automated pass is not a visual acceptance, and an RDP throughput sample is not a local-display visual comparison.
- Preserve research history, but remove stale “current/next” claims from living documents once the state advances.
