Docs: LANTERN roadmap index + Phase 4/5 design passes + session log B

- Roadmap_Lantern_Slice: Phase-0 status callout + doc index (all Phase-0 artifacts linked).
- Phase 4 (mutations): mostly a re-theme of the shipped boon overhaul (DR-047) + Gloam gating
  + Tallow fixing (persistence) + raw-socketing + culture library; salvage map + gate.
- Phase 5 (death/recovery): the split, stranded suits (deterministic relocation), body-carry,
  flame-share revive, the Tender solo valve, Selkie tariff; builds on the world-model
  in-pocket-death decision (C4); the slice's 2nd falsifiable-test half.
- Session log Part B: the autonomous design pass + the world-model review record.

+# Session 2026-07-13 (Part B) — LANTERN Phase 0.3 review + autonomous design pass
+
+> Continuation of [[2026-07-13_Lantern_Phase0_Adoption_Pivot]] (Part A = the pivot). Operator directed:
+> *"continue with everything you can in the roadmap — commit as you go, don't stop; create a doc of operator
+> questions as needed; only stop at a hard blocker with nothing else to work on"* then stepped away. This is
+> an autonomous **design/documentation** run — no Unity code (all LANTERN code is greenfield netcode-touching →
+> needs plan-approval + a focused editor + the ★review-first ritual; parked in [[Lantern_Operator_Questions]]).
+
+## Goal
+
+Advance the LANTERN roadmap as far as possible without a focused editor or operator input: run the Phase-0.3
+world-model design review, then produce the "deeper technical pass" design/build-spec scaffolding.
+
+## Done
+
+**Phase 0.3 — world-model design review (the ★ gate):**
+- Grounded the real code (3 read-only Explore passes: relevancy/region · run-room lifecycle · save/procgen) +
+  ctx7 on `GhostRelevancy`/`GhostImportance`. Locked two operator forks (co-located party; party light-union).
+- Wrote the design proposal ([[Lantern_World_Model_Design_Proposal]]), then ran the **adversarial design-review
+  Workflow** (`wf_aa6fb661-e25`; 22 agents, **0 failures** — checked the failures list per the standing rule;
+  findings are real, not the masquerading-empty trap). **18 findings, 12 CONFIRMED + 6 PARTIAL, 0 refuted.**
+- The review caught real design-breakers before any code: seed-model self-contradiction (DP-1/RS-1),
+  wrong persistence-lifecycle (DP-2), invariant-breaking respawn-to-base (NR-2/RS-3), phantom-kill VFX (NR-1),
+  undodgeable dark hits (NR-3), the ~23-site `RegionTag→PocketTag` semantic rewrite (RS-2).
+- Synthesized → [[World_Model_Build_Spec]] (review-hardened contract, all 18 folded + findings ledger + build
+  order + open risks). Recorded [[DR-049_Lantern_World_Model_Design]]. **Design half of Phase 0.3 passed.**
+
+**Deeper technical pass (design scaffolding):**
+- [[Lantern_Phase1_Combat_Gym_Build_Spec]] — two frames, 4-socket manual-aim kit, 5 Sparks, on the salvaged
+  ability/boon pipeline (grounded in a combat/ability/boon Explore pass).
+- [[Lantern_Art_Pipeline_Recipes]] — the material foundation (palette atlas + 3 master shaders) + statics/
+  skinned recipes + 3 rig families + CreatureKit (Workstream A0/A1/A2).
+- [[Lantern_Currency_ReMean]] — Ore/Aether/Biomass/Charge → the 7 light currencies + byte ids.
+- [[Lantern_Tone_Bible]] — Phase-7 register bounds per voice (before any bark generation).
+- [[Lantern_Phase4_Mutations_Design]] — mutations = the DR-047 boon layer re-themed + Gloam/Tallow/culture.
+- [[Lantern_Phase5_Death_Recovery_Design]] — the split, stranded suits, flame-share, the Tender, the Selkie.
+- [[Lantern_Operator_Questions]] — running parking lot (code impl, extra reviews, A0 art, design forks).
+- Roadmap index updated ([[Roadmap_Lantern_Slice]] Phase-0 status + doc links).
+
+## Decisions
+
+- [[DR-049_Lantern_World_Model_Design]] — the review-hardened world-model design accepted (Build Spec is the contract).
+
+## Open / deferred (hard blockers for autonomous work — see [[Lantern_Operator_Questions]])
+
+- **Code implementation** — all LANTERN code is greenfield netcode-touching; needs plan-approval + a focused
+  editor (unfocused throttles MCP + breaks Burst) + the per-slice ★review. NOT started autonomously.
+- **A0 in-engine style-proof scene** — the one open Phase-0 gate; needs a focused editor + operator eyes.
+- **Additional ★ design reviews** (Phase-1 light-relevancy, Phase 2 world code, etc.) — did not fire more heavy
+  Workflows unprompted beyond the one greenlit.
+- New design forks surfaced by the review (dark-contact policy, lantern placement granularity, END-1/EB-1
+  mothball timing) + the Phase-1 forks — all parked with recommendations.
+
+## Next
+
+Operator on return: (1) answer the parked questions (one pass); (2) focus Unity + greenlight Phase-1
+implementation from the build spec (or the world-model Phase-2 code from the Build Spec's build order); (3)
+judge the A0 style-proof scene when the art track produces it. Everything is designed + reviewed so code can
+move fast.
