Erik 11a8742884 docs: scope C4 routes 6 and 7 — route 6 needs zero production lines
Scoped together because both concern item/container placement; they turn out to
share no production file, but the shared inventory premise had to be corrected
once rather than twice.

The governing correction: both routes' inventory sections rest on
"RegisterEntityWithInitialResidence is never called from any production path."
C3c (529e0e9d) made that false — LiveEntityRuntime.cs:544-548 and
RuntimeLiveEntitySessionController.cs:118-123. Every conclusion reasoning from
"nothing upstream to cancel" is obsolete.

Route 6 (drops) is COMPLETE. No route-6 disposition exists: a dropped item is
Remote + TopLevel -> SetPosition/Placement|Slide, which is route 1's
classification exactly, and both drop flavors already converge on
LiveEntityHydrationController.OnCreate (split-recovery at
InventoryWorldDropProjectionController.cs:66). BuildSpawn overrides every
positional field, so the stale-source-position requirement is met.

Route 6 also retires a false premise in this campaign's own plan
(2026-08-02-placement-cutover.md:98-100): "replay create-time effects" is NOT
established as a defect. acdream's only create-time replay is the F754/F755
queue keyed by GUID, which is retail's own HandleCreateObject @0x00454C80
behaviour. The one plausible mechanism — a cloned DefaultScriptType — never
fires at create in either client; retail's play_default_script is reached only
from DoCollision @0x0058C3A0 and the hook dispatcher @0x00526C08/@0x00526C14.
And retail's "split-recovery marking" is a SELECTION transfer, not effect
suppression: UIAttemptSplitTo3D @0x0058D850 records WCID/stack/time and
DeclareValid @0x0058E340 re-selects at @0x0058E481. That port is missing but is
selection UX, not placement — file it outside C4.

Route 7 is one slice, ~300-490 lines, and must not be split: the Runtime commit
and the App demotion are two halves of one transfer. Retail performs NO
placement here — DoPickupEvent @0x00452240 is unset_parent + leave_world;
DoParentEvent @0x00452290 is set_parent + SetPlacementFrame. No SetPosition, no
leash. So route 7 inverts 4b-2's rule: never arm ConstrainTo.

Route 7's real defect: the child's canonical cell has two writers. Retail
re-cells inside set_parent (change_cell @0x00515AD6 + recalc_cross_cells
@0x00515B15); acdream commits the child cell-less in Runtime and re-cells it
from a RENDER TICK (EquippedChildRenderController.TickChild:408 ->
RebucketLiveEntity). Headless has no such controller, so every headless
parented child stays cell-less forever — the headless gap and the two-writer
split are the same bug.

Load-bearing unestablished item, recorded rather than guessed: whether retail
re-cells children when the parent crosses a cell. UpdateChild @0x00512D50 ->
set_frame @0x00514090 is frame-only and never writes objcell_id;
change_cell/set_cell's child handling was not read. Settle that before
demoting App's rebucket — demoting it blind risks route 4a's R1 / #184
invisible-but-solid.

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 46.
  • Structural/runtime state: all eight GameWindow decomposition slices, Modern Runtime Slices AJ, and the connected visual/lifecycle gates are complete. GameWindow is a 1,622-line composition/callback shell. AcDream.Runtime.GameRuntime owns 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.Headless is 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 66f114b2 and 11501d52. Native Windows passes the active modern-GL/audio/window smoke. WSLg X11/Wayland correctly reject their missing GL_ARB_bindless_texture. Physical-Linux validation and L2L6 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:

  1. plans/2026-05-12-milestones.md — the active playable outcome, freeze boundaries, and visual gates.
  2. plans/2026-04-11-roadmap.md — strategic phase ledger: shipped, active, deferred, and future work.
  3. ISSUES.md — tactical defects and small follow-ups. The status inside an issue is authoritative; physical order is not.
  4. architecture/retail-divergence-register.md — every known place runtime behavior can differ from retail.
  5. architecture/acdream-architecture.md and architecture/code-structure.md — ownership, dependency, update-thread, and extraction rules.
  6. 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/ and superpowers/plans/ are per-slice design and execution records. Completed plans remain historical.
  • audit/ contains completion and conformance audits.
  • reference/ace-commands.md preserves the local ACE server's complete in-game command catalog and points to the authoritative per-command help surface.

Durable memory

  • ../claude-memory/MEMORY.md indexes 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.md is 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→R8 architecture 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.
