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Docs/skills sweep: Pillars pointers + LANTERN locked decisions; superseded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.

+# DR-048 — LANTERN adoption: the full pivot
+
+## Context
+
+The 2026-07-13 vision refresh ([[Theme_Direction_Candidates]]) explored four load-bearing-theme
+directions against the operator brief (**V Rising + Shape of Dreams** core; SoD-grade skillshot combat +
+modular ability kits braided with a persistent base; 2–4 co-op; solo dev learning Blender, RoR2-lineage
+low-poly). The operator selected **Direction A — LANTERN** and put a full identity draft through **three
+independent adversarial reviews** (theme/narrative · systems/game-loop · player-experience/market). All
+findings were operator-accepted and folded into the review-hardened final draft [[Identity_Lantern]] (v3),
+with the vertical-slice roadmap [[Roadmap_Lantern_Slice]].
+
+This forces a direction decision: the codebase and vault were built under **The Awakening Engine**
+(Aether-colony sci-fi fiction, [[Identity]] / [[DR-015_The_Awakening_Engine_Fiction_Adoption]]) and most
+recently steered by the **Co-op Hades conversion** iteration ([[Iteration_2026-07_CoopHades]], which
+itself superseded the DR-037 → DR-042 expedition-driven line and the DR-035 end-of-month jam slice). LANTERN
+keeps every locked **mechanical** pillar ([[Pillars]] #1–4 hold) but replaces the **fiction, the world
+model, the death rules, the build/mutation system, and the combat feel target**. It is not a reskin — under
+LANTERN's own load-bearing test, reskinning "light" would break persistence, death, relevancy, the economy,
+and the treadmill at once. This is a genuine change of direction, so it is recorded as one.
+
+## Decision
+
+**LANTERN is the operative direction.** [[Identity_Lantern]] is the authoritative design; [[Roadmap_Lantern_Slice]]
+is the operative roadmap. This DR is the **adoption gate** (Phase 0.1 of that roadmap).
+
+1. **Supersession (archive, never delete).** LANTERN supersedes, as the *operative target*:
+   - the Awakening-Engine fiction — [[Identity]] / [[DR-015_The_Awakening_Engine_Fiction_Adoption]];
+   - the Co-op Hades iteration — [[Iteration_2026-07_CoopHades]];
+   - and by transitivity the direction line it carried (DR-037 expedition spine → DR-042 expedition-driven
+     win → DR-044/045/046 demo passes → DR-047 boon overhaul).
+   All of it is **kept as history and as salvage quarry** — banners point forward, nothing is removed. Prior
+   DRs stay valid as records of what was built and why.
+
+2. **Existing code is quarry, not foundation.** Strip and reuse freely; no design decision bends to preserve
+   code. The system-by-system keep / rework / mothball calls live in [[Lantern_Strip_Mothball_Inventory]]
+   (Phase 0.2). Headline calls, from the roadmap's standing constraints: **combat feel layer + telegraphs =
+   keep**; **boon pipeline = rework into wild mutations**; **regions/relevancy, save system, hub lifecycle =
+   rework**; **sieges / Core / turret-ammo economy leftovers = mothball**.
+
+3. **The mechanical pillars hold; the fiction and three subsystems change.** Unchanged: Unity DOTS +
+   Netcode for Entities, server-authoritative, input-only clients, client prediction, 2–4 co-op
+   ([[Pillars]]). Changed by LANTERN: (a) **world model** → seed-pinned **pocket-graph** with light-as-
+   permanence (the tide-line); (b) **combat feel** → SoD-grade **manual-aim skillshots** (the soft
+   auto-target era ends as the target — see the pillars note); (c) **build system** → suit-frames + cultured
+   **Sparks** + wild **mutations** (the augment layer), replacing flat-stat boons.
+
+4. **The slice's falsifiable test is the only gate that matters:** *does pinning a pocket feel like winning
+   something, and does a stranded suit feel worth a second descent?* Every deferred system is justified only
+   by these two.
+
+5. **Phase 0 exit is NOT this DR alone.** The roadmap gates Phase 0 on **three** things: this DR merged **+**
+   the world-model design review passed ([[Lantern_World_Model_Spike]], ★review-first — not yet run) **+**
+   the A0 style-proof scene approved in-engine ([[Art_Direction_Lantern]], gate pending). This DR closes only
+   0.1; 0.2 (inventory) is delivered; **0.3 and 0.4's in-engine gates remain open.**
+
+## Consequences
+
+- **Naming.** Working title "LANTERN" has poor Steam-search uniqueness; a shipping-title pass is deferred to
+  a marketing milestone (per [[Identity_Lantern]]). "LANTERN" is the internal codename until then.
+- **Vault surface updated this session (Phase 0 pivot):** [[Pillars]] (pointer + LANTERN locked decisions),
+  [[Identity]] + [[Iteration_2026-07_CoopHades]] + [[Path_to_Fun]] (superseded banners), [[Home]] (MoC +
+  current direction), [[Systems_Index]] (era note), `CLAUDE.md` (game-state/core-loop line → LANTERN pivot
+  pointer; verbose co-op-Hades invariants archived to `_Meta/CLAUDE_Build_Gotchas_Archive.md`). Prior DRs and
+  session logs are **not** rewritten — they are the record.
+- **basic-memory** reindexes this DR and the new roadmap/vision docs on next index; native `memory/`
+  gets the [[lantern-direction-pivot]] operative-direction note. The old direction memory is kept as history.
+- **What does NOT change yet:** no world code, no fiction rename in code, no ghost/RPC churn. The pivot is a
+  documentation + direction adoption; implementation begins at Phase 1 (combat gym) and only after the Phase 0
+  world-model review passes for anything world-touching.
+- **Revisit when:** the slice test fails on either half (pinning doesn't feel like winning, or a stranded suit
+  doesn't pull a second descent) — that invalidates the direction, not a subsystem, and triggers a fresh
+  fork-locking ritual. Also revisit the "crews present-but-unlit vs gone" and shipping-title open forks at the
+  narrative/marketing milestones.
