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Docs/skills sweep: Pillars pointers + LANTERN locked decisions; superseded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

+# Session 2026-07-13 — LANTERN Phase 0: adoption & the full docs/skills pivot
+
+## Goal
+
+Start Phase 0 of the LANTERN roadmap ([[Roadmap_Lantern_Slice]]): **make the full pivot** — adopt LANTERN as
+the operative direction and update **all docs & skills** to reflect it, plus deliver the Phase-0 items that are
+documentation work. No code this session (the pivot is a direction adoption; implementation starts at Phase 1).
+
+## Done
+
+**Phase 0 checklist items (doc portions):**
+- **0.1 Adoption** — wrote [[DR-048_Lantern_Adoption_Full_Pivot]] (LANTERN supersedes the Awakening-Engine
+  fiction + the Co-op Hades iteration; archive-not-delete; existing code = quarry; mechanical pillars hold).
+- **0.2 Strip/mothball** — wrote [[Lantern_Strip_Mothball_Inventory]]: system-by-system keep / rework /
+  mothball / cut, grounded in [[Systems_Index]] + the co-op-Hades systems. Headlines: combat feel + telegraphs
+  = keep; boon pipeline → mutations; regions-relevancy / lifecycle / save → rework; automation +
+  sieges/Core/turret = mothball.
+- **0.3 World-model spike** — wrote [[Lantern_World_Model_Spike]] as a **★review-first BRIEF** (pocket-graph +
+  seed-pinning + light-as-information relevancy + Bell transit contract, with the open questions + known
+  hazards for the review). Marked review-PENDING; no world code until the adversarial review passes.
+- **0.4 Art A0** — wrote [[Art_Direction_Lantern]]: the binding style bible, **the material decision** (one
+  palette atlas + vertex colours under three master shaders `Lit-Palette`/`Emissive-Gloam`/`Skinned-Palette`),
+  the reference board, and the style-proof-scene gate definition. The in-engine scene itself = pending.
+
+**"Update all docs & skills" sweep:**
+- [[Pillars]] — LANTERN direction banner up top + a LANTERN locked-decisions block; Related repointed to
+  [[Identity_Lantern]] (prior [[Identity]] marked superseded/quarry).
+- Superseded banners → [[Identity]], [[Iteration_2026-07_CoopHades]], [[Path_to_Fun]] (redirected straight to
+  LANTERN; `status: active`→`superseded`). Kept as history; nothing deleted.
+- [[Home]] MoC — current-direction callout = LANTERN; vision/roadmap/session/decision pointers refreshed; the
+  stale "serena navigates C# symbols" line fixed to Glob/Grep (serena removed 07-07).
+- [[Systems_Index]] — era note: the catalogued systems are the pre-pivot spine = quarry, verdicts in the
+  inventory.
+- `CLAUDE.md` — the "Core loop" bootstrap bullet replaced with a **LANTERN direction pointer** (net-neutral:
+  39,684→39,681 B, under the 40 KB budget); the verbose DR-044/045/046 core-loop invariants archived verbatim
+  to `_Meta/CLAUDE_Build_Gotchas_Archive.md` under a new 2026-07-13 heading (the general "serialized prefab
+  bool ignores the C# initializer" gotcha kept inline). Condensation-history line ticked.
+- `dots-dev` skill — `references/validation-harness.md`: noted the "expedition-run" driving recipe's nouns are
+  co-op-Hades-era (re-meaned to the descent lifecycle later); the harness *patterns* stay direction-agnostic.
+  The rest of the skill is process-only and needed no pivot.
+- Native memory — new [[lantern-direction-pivot]] operative-direction note + `MEMORY.md` index; the prior
+  direction memory kept with a supersession pointer.
+
+## Decisions
+
+- [[DR-048_Lantern_Adoption_Full_Pivot]] — LANTERN is the operative direction (Phase 0.1 gate closed).
+
+## Open / deferred (explicitly flagged — NOT silently deferred)
+
+Two Phase-0 items are **not** doc work and remain OPEN gate conditions:
+1. **0.3 world-model design review** — the ★review-first adversarial Workflow over [[Lantern_World_Model_Spike]]
+   + ground-truth relevancy/lifecycle/save code, producing `World_Model_Build_Spec.md`. This is the slice's
+   hardest netcode problem; no world code until it passes.
+2. **0.4 A0 style-proof scene** — one prop + one creature + one suit in-engine under murk, judged full-size +
+   200 px + grayscale. Requires Blender + engine work (Workstream A0 gate).
+
+Phase 0 does not fully exit until both land. Phase 1 (the combat gym) has **no world** and is not blocked by
+0.3 — it can start on the KEEP/rework salvage once the operator chooses.
+
+## Next
+
+Operator fork: (a) run the **0.3 world-model design-review Workflow** now, or (b) start the **0.4 style-proof
+scene** (Blender on-ramp), or (c) begin **Phase 1 combat gym** planning from the salvage inventory. Recommend
+(a) since it unblocks all world-touching work and is the standing review-first ritual, with (b) proceeding in
+parallel on the art track.
