Erik 7e6033d0ad refactor(runtime): own per-session physics simulation
Move the sole PhysicsEngine, production cache, collision admissions, canonical bodies and hosts, remote components, ordinary/remote worksets, simulation, cell commits, and shadow synchronization under RuntimeEntityObjectLifetime. Keep App as the prepared-asset, animation-input, and render-projection adapter while preserving the named-retail update and collision order.

Add exact-incarnation, object-clock, callback-reentrancy, GUID-reuse, two-runtime isolation, source ownership, collision publication, and graphical projection coverage. Release build and the complete 8,588-test solution pass.

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 — 2026-07-26

  • Milestone state: M3, “Cast a spell,” landed 2026-07-21. M4, “Live in the world,” is active.
  • M4 gameplay program (paused while the authorized performance program executes): the pre-M4 world-interaction completion program in plans/2026-07-23-world-interaction-completion.md. The eight-slice GameWindow decomposition and its connected visual matrix are complete.
  • Current active engineering program: Slices AI, J0J4, and J5.1J5.4 of plans/2026-07-24-modern-runtime-architecture.md are complete. Production uses prepared world/collision packages, typed residence, retained render-scene/delta submission, bounded frame owners, and flat-authoritative collision without parsed-graph production residency. Runtime owns canonical session/transport, entity/object lifetime, J4 gameplay state, selection/interaction transactions, and combat/magic intent. App materialized projections and retained widgets borrow exact Runtime identity and action owners. J5.5 per-session physics and remote simulation is next in plans/2026-07-26-modern-runtime-slice-j5.md.
  • Completed gates: R6 locomotion/collision/projectile/teleport/radar and the final two-client portal-out/materialization observer comparison (#218).
  • Separate visual verification: the shared-alpha lifestone/particle result in #225; its connected resource-lifetime and performance routes pass.
  • Carried behavior debt: #153 (far teleport onto an unstreamed edge), #116 (two narrowed slide-response cases), and divergence rows TS-50/TS-51.
  • Active engineering track: complete Slice J's coherent Runtime lifetime groups, then build the approved Linux/headless multi-session host in Slice K. J5.4's exact rollback is git revert aa3f4a60f87f2cbebc3d8ecd5e33d779b7fb13c1.
  • Divergence audit: 178 active rows — IA 17, AD 37, AP 85, TS 34, and UN 5 — plus the retained retired TS-37 history note.
  • Latest automated baseline: Release build succeeds; 8,575 tests pass and five are intentionally skipped. The exact J5.4 connected lifecycle/reconnect gate completed two sessions and seven checkpoints, and its canonical nine-stop movement route completed all destinations and movement exercises, with graceful zero-code exits and zero failures.

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.

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.
