Docs: LANTERN Phase 0 — full pivot adoption + all-doc sweep

Adopt LANTERN as the operative direction (co-op action-RPG, light-as-territory),
superseding the Awakening Engine fiction + the Co-op Hades iteration. Existing
code becomes salvage quarry; the mechanical pillars hold.

Phase 0 deliverables (doc portions):
- DR-048 adoption decision record (0.1)
- Lantern_Strip_Mothball_Inventory — system-by-system keep/rework/mothball (0.2)
- Lantern_World_Model_Spike — pocket-graph + seed-pinning BRIEF, review-first (0.3)
- Art_Direction_Lantern — style bible + material decision + A0 gate (0.4)

Docs/skills sweep: Pillars pointers + LANTERN locked decisions; superseded
banners on Identity, Iteration_CoopHades, Path_to_Fun, Milestones, Backlog,
End_Of_Month (all redirect to the LANTERN roadmap); Home MoC + current-direction
callout (and stale serena line fixed); Systems_Index era note; CLAUDE.md
core-loop line -> LANTERN direction pointer (verbose co-op-Hades invariants
archived to the gotchas archive, net-neutral under the 40 KB budget); dots-dev
validation-harness expedition-run recipe flagged era-specific.

Two Phase-0 gate items remain OPEN (not doc work): the 0.3 world-model design
review and the 0.4 in-engine style-proof scene.

 - `ProjectM.Simulation.GameBootstrap : ClientServerBootstrap` overrides `Initialize` with `AutoConnectPort = 0` (M4 — listen/connect is explicit via the `ConnectionConfig` singleton + per-world ConnectionControlSystems). **Editor default = instant-into-game + MPPM** (creates `ServerWorld` (`WorldFlags.GameServer`) + `ClientWorld` (`WorldFlags.GameClient`)); the `ProjectM/Boot Into Menu (Editor)` EditorPref flips the MAIN editor to the frontend path. **Player builds boot the UITK frontend menu** (`return false` → one menu world, no netcode worlds until a menu choice). See [[DR-019_Frontend_Menu_Settings_Saves_Build]].
 - **Scenes:** `Assets/Scenes/MainMenu.unity` (build index 0) boots the UITK frontend (menu world only); `Assets/Scenes/Game.unity` (index 1) holds gameplay with `Assets/_Project/Subscenes/Gameplay.unity` wired in as the baked subscene (GameObject `GameplaySubScene`). `SampleScene`/`DevSandbox` are kept as reference/dev scenes. The on-demand lifecycle (`WorldLauncher`/`SessionRunner`/`MainMenuController`) creates the right worlds per menu choice (Single/Host/Join), THEN `LoadScene(Game)` (subscene-streaming rule above).

Rooms spawn per `RoomEpoch`, `RoomTag`-torn-down, gate on a PORTAL (`RunLifecycle.RoomExplore=6` loot window; `PortalInteractRequest`→server `PortalCommand`). Class + per-run PREP spent at base (Staging-gated RPCs via shared `ClassSwapUtil`; prep `StatModifier` band stripped on Returning). `Health.Max` is a `[GhostField]`.
