docs(runtime): close character projections

Record J4.4's canonical character settings, borrowed gameplay views, typed state-command seam, complete Release evidence, exact-binary lifecycle/reconnect acceptance, rollback, and the J4.5 combined closeout boundary. Synchronize architecture, roadmap, milestones, agent guidance, and durable memory.

+# Modern runtime J4.4 — character projections and typed state commands
+
+**Status:** COMPLETE
+**Production commit:** `dcb61efb5af6c12bd619369e28cf11bacc37bc73`
+**Parent plan:** `../plans/2026-07-26-modern-runtime-slice-j4.md`
+
+## Result
+
+`RuntimeCharacterState` now owns the remaining presentation-independent local
+character state: both character-option bitfields and the server-authoritative
+run/jump skill projection. The App-owned `PlayerCharacterOptionsState` and
+`LocalPlayerSkillState` were deleted. The graphical movement controller
+borrows and applies the Runtime values when its body is constructed or
+reconstructed.
+
+The current-runtime boundary exposes borrowed, immutable projections over the
+exact J4 owners:
+
+- inventory request/busy state, complete item-or-spell shortcuts, and item
+  mana;
+- character options, movement skills, vitals, attributes, skills, learned
+  spells, favorites, filters, desired components, enchantment counts, and
+  revisions;
+- friends, squelch counts/revisions, and negotiated chat-room state.
+
+Synchronous, generation-gated typed commands now cover shortcut mutation,
+spell favorites/filter/forget/component preferences, advancement, character
+options, friends, and squelch. The retained graphical UI uses this same seam.
+The adapter publishes into the existing generation-scoped `ICommandBus`; the
+exact live-session router performs the established `WorldSession` sends and
+becomes inert before session detachment. No asynchronous queue, second state
+collection, or extra frame was introduced.
+
+Normalized checkpoints now include J4 inventory, character, and social
+revisions/counts, so later graphical-versus-no-window parity gates cannot pass
+while ignoring the newly exposed state.
+
+## Retail basis
+
+J4.4 changes ownership and command routing, not game behavior. The retained
+defaults come from the named retail client:
+
+```text
+PlayerModule::PlayerModule @ 0x005D51F0
+    options_       = 0x50C4A54A
+    options2_      = 0x00948700
+    spell_filters_ = 0x00003FFF
+```
+
+`PlayerModule::Clear @ 0x005D48A0` clears the per-character shortcut,
+desired-component, generic-option, and gameplay-option objects. Because one
+modern Runtime owner survives successive character sessions, its session reset
+restores the equivalent freshly constructed option bitfields. Existing
+PlayerDescription replacement and `SetCharacterOptions (0x01A1)` packing are
+unchanged.
+
+Controller/body/camera/input application remains in App and is intentionally
+outside J4; J5 owns that later boundary.
+
+## Automated evidence
+
+- Runtime suite: 169 passed.
+- App suite: 3,777 passed / 3 established skips.
+- Core suite: 3,305 passed / 2 established skips.
+- Core.Net suite: 600 passed.
+- UI abstractions: 545 passed.
+- Content: 119 passed.
+- Bake: 15 passed.
+- CLI: 4 passed.
+- Complete Release solution: 8,534 passed / 5 established skips.
+- Release build: pass, zero warnings and zero errors on the final incremental
+  build.
+- `git diff --check`: pass.
+
+Focused coverage proves the retail defaults, partial run/jump updates,
+character replacement/reset, full item and spell shortcut observation,
+borrowed owner identity, typed command/generation routing, displaced-session
+inertness, normalized checkpoint coverage, two independent Runtime instances,
+absence of static mutable session state, and deletion of both App owner paths.
+
+## Exact-binary connected evidence
+
+`logs/connected-world-gate-20260726-091340/report.json` passed on exact source
+and embedded binary commit
+`dcb61efb5af6c12bd619369e28cf11bacc37bc73`:
+
+- six capped checkpoints through login, outdoor/dungeon/facility travel and
+  revisit plus one fresh-process uncapped reconnect checkpoint;
+- 243.602-second capped route and 61.262-second reconnect route;
+- both sessions exited gracefully with code zero;
+- zero failures, render-shadow mismatches, pending deltas, or stranded owner
+  work.
+
+Its only warning is the established set of 25 expected world-edge landblock
+misses.
+
+## Divergence audit
+
+The slice preserves existing retail-derived packet order, option defaults,
+movement-skill application, and command builders while changing only lifetime
+ownership and the host boundary. No divergence row was added or retired.
+
+## Rollback
+
+```text
+git revert dcb61efb5af6c12bd619369e28cf11bacc37bc73
+```
+
+Revert J4.4 before J4.3 if the gameplay-state groups must be unwound. Do not
+revert J3's canonical entity/object ownership to mask a J4 state or command
+failure.
+
+## Next boundary
+
+J4.5 removes the remaining compatibility paths, proves graphical and
+no-window command/state parity under injected failures, and runs the combined
+Release, connected lifecycle/reconnect, and canonical nine-stop closeout.
