Docs: align CLAUDE.md + vault to scene-split / Automation / Saves / UITK

CLAUDE.md: rewrite Bootstrap&worlds (scene split + on-demand frontend), add M7 Automation + disk-persistence + UITK HUD bullets, new build-gotchas, note new folders fit existing asmdefs. Vault: Milestones (M6 + polish pass -> Done; HUD + cleanup rows), Backlog (ConnectionUI done + cleanup notes), Home/Systems_Index dates. Add the 3 prior session logs + DR-019/020/021 + the 2026-06-06 cleanup log + screenshots.

 > **2026-06-04 World-space cohesion pass** ([[2026-06-04_World_Space_Cohesion_Pass]], [[DR-018_World_Space_Cohesion_Pass]]) — delivered + validated (EditMode 127→**142**): **destructible "clearing"** (`BlightClutter` ghost smashed by the **unified** harvest sweep → Biomass scrap + smash juice, scattered/cleared with the expedition field); **build out the base** (additive `Wall`=5 / `Pylon`=6 buildables — Wall blocks the player, V/N keys); and a first **visual cohesion layer** (Aether cyan/orange material pair, the 3 new ghosts recoloured, the barren +1000 Blightfield turned into a 21-piece Synty rock/debris basin + orange wild-lights — relief via props, **no terrain**). In-editor Play introspected via execute_code; a 4-lens adversarial review (23→4) caught + fixed an immortal-shot-sink (fractional `ScrapPerHit` truncation). Base-side cohesion accents + clearing-as-gating deferred (see the 2026-06-04 follow-ups below).

Editor instant-play + MPPM loop unchanged by default.
+

+
+> **2026-06-06 Cleanup & alignment** ([[2026-06-06_Cleanup_Alignment]]) — repo hygiene before more dev (no gameplay change): deleted crash-recovery scenes (`_Recovery/`) + a stray empty `Assets/Resources.meta`; removed the legacy IMGUI `ConnectionUI` (3 scenes + script + 4 stale comments); DRY'd the duplicated UITK `Round`/`Border` helpers into `MenuUi` (canonical) + small HUD/build-input tidy (husk-count cache, table-driven build hotkeys); re-aligned `CLAUDE.md` (scene split, on-demand frontend, M7 Automation, disk persistence, UITK HUD, new build-gotchas) + the vault roadmap to the three 2026-06-05 sessions. EditMode green, console clean; landed as grouped commits.
+
+### 2026-06-06 Cleanup follow-ups
+- [ ] **Optional further code-tidy** (low value; deliberately skipped this pass to limit churn on freshly-validated systems — none affect behavior): `SettingsService` migrate-then-clamp ordering; `ConveyorTransportSystem`'s 6 parallel snapshot arrays → one struct array; `WorldFeedbackSystem.TintForResource` if-chain → byte→Color lookup; `PlayerInputGatherSystem` device-active dedup. [[2026-06-06_Cleanup_Alignment]].
+
+### 2026-06-05 M7 Automation follow-ups
+- [ ] **Throughput visuals** (item-on-belt): server-only machine buffers don't reach the client (clients see only `PlacedStructure.Type`); add ONE small replicated byte if live belt visuals are wanted.
+- [x] **Build-palette HUD + ghost preview** — done 2026-06-05: UITK build-palette bar (6 buildables + cost + affordability + selection) + click-to-place with a green/red ground ghost, conveyor rotate, fire-suppress. Conveyor-facing arrow/icons still open. [[DR-021_HUD_UITK_BuildPalette]], [[2026-06-05_HUD_Rework_UITK_BuildPalette]].
+- [ ] **Relevancy ceiling** — `RegionRelevancySystem`'s O(structures×connections)/tick scan becomes load-bearing at higher conveyor counts (DR-014 ceiling note); batch it when counts grow.
+- [ ] **Recipe depth** — multi-input fabricator recipes; fabricator→conveyor output chaining (additive: give the fabricator a `MachineOutput`); per-machine distinct meshes (machines reuse the Turret mesh as a placeholder).
+- [ ] **Operator live play-through** of the chain + a real 2-build LAN run under latency (single-client validated this pass).
+
+### 2026-06-05 Game-infrastructure follow-ups
+- [x] **Build the standalone** — the first player build hit a pre-existing URP blocker (`UniversalRenderPipelineGlobalSettings` `m_AssetVersion=11` > package `k_LastVersion=10`, from the reverted 6.6 alpha; URP migrates forward-only so its build preprocessor rejected it — blocked builds, not editor Play). Fixed (reset the stamp to 10); `ProjectM/Build/Windows Player` now produces a complete Mono Win64 standalone (`Builds/Windows/`, both scenes + baked subscene). See [[2026-06-05_Game_Infrastructure_Menu_Settings_Saves]].
+- [ ] **Operator-run validation**: launch `Builds/Windows/ProjectM.exe` → confirm it boots the menu → Single/Host/Join play; a real **2-build LAN Host↔Join**; MPPM co-op regression in default-editor mode.
+- [ ] **Controls settings + key rebinding** (Input System rebinding UI) — deliberately out of the Graphics/Audio scope this pass.
+- [ ] **Full base-state saves** (placed structures / threat / storage) — the `SaveData` schema is versioned so this is additive (no migration of the ledger/goal slice).
+- [ ] **Unity Relay** for remote (non-LAN) Host/Join — swap the endpoint source feeding `ConnectionConfig` (the frontend lifecycle is transport-agnostic).
+- [ ] **Dedicated-server build** — the `RequestedPlayType==Server` auto-host branch is in but UNTESTED this pass.
+- [x] **Remove the legacy IMGUI `ConnectionUI`** — done 2026-06-06 (cleanup pass): the `NetConnectionUI` GameObject removed from `Game.unity` / `DevSandbox.unity` / `SampleScene.unity`, `ConnectionUI.cs` deleted, and the 4 stale doc-comments repointed to the UITK `MainMenuController` / `WorldLauncher`. The UITK frontend menu now owns Host/Join+IP everywhere. [[2026-06-06_Cleanup_Alignment]].
+- [ ] **Volume-slider theming**: sliders render via the default runtime theme; if a real build shows them unstyled, swap to +/- cycle rows (the enum settings already use cycle rows).
 - [x] Upgrade Unity 6.4 → 6.6 — done (now `6000.6.0a6`). Entities/Collections/Graphics → 6.5.0; **Netcode → 6.6.0 and Physics → 6.5.0 also renumbered into the editor line** (not independent 1.x as [[DR-001_Netcode_Test_Harness]] assumed). See [[2026-05-30_M1_Player_Slice]].
 - [x] Define the core gameplay loop and the first predicted player ghost — delivered as M1 ([[2026-05-30_M1_Player_Slice]]).
 - [x] **Re-validate the M1 play-tick on a stable Unity 6.x** — moot/subsumed 2026-06-04: M1–M6 are all runtime-validated on the stable **6.4.7** line (the 6.6 alpha netcode bug never affected 6.4.7). The original "blocked on 6.6 alpha" framing ([[DR-002_Unity66_Alpha_Netcode_Transport]]) no longer applies.

 - [x] Optional template cleanup: remove `com.unity.visualscripting`, `Assets/TutorialInfo/`, `Assets/Readme.asset` — **done 2026-06-03** (pre-M6 cleanup; see the "2026-06-03 Visual & Controls Polish" section below + [[2026-06-03_Pre_M6_Cleanup]]). Duplicate of the now-checked item there.

 - [x] Decide home-base **grid 2D vs 3D** before M6 — resolved 2026-06-02: **planar single-level `int2` grid**, CellSize 1.0, 32×32 plot (full 3D/stacked deferred). Locked in `BaseGridMath` — [[DR-008_M5_HomeBase_BaseLayer_Storage]].

+- [x] Decide **production replication** (predicted vs server-only) before M7 (automation) — resolved 2026-06-05: **server-only** (production runs in the plain server `SimulationSystemGroup` `[UpdateAfter(PredictedSimulationSystemGroup)]`; results replicate via the existing global ledger + `PlacedStructure` ghosts, never predicted; per-machine I/O buffers stay server-only). Delivered as **M7** ([[DR-020_M7_Automation_Production_Chains]], [[2026-06-05_M7_Automation]]).
 - [x] **M2 follow-up — Burst cache health** — confirmed clean 2026-06-03: warm focused play shows **no** "not a known Burst entry point" managed-fallback messages + fast (~3s) play-enter. The M2-era corruption is gone. [[2026-06-03_Pre_M6_Cleanup]] (orig [[2026-05-31_M2_Combat]] / [[DR-003_M2_Combat_Netcode_Architecture]]).
 - [ ] **M2 follow-up — live interactive fire test** (focused Play Mode: press Space / LMB / RT → predicted projectile + dummy HP drop). The server combat loop + replication are validated; the input→`AbilityFireSystem`→predicted-spawn→classification path is only validated structurally.
 - [x] **M2 follow-up — mouse-cursor aim for KBM** — done 2026-06-03: client-side camera ground-ray cursor aim rides the existing `PlayerInput.Aim` `[GhostField]` (no new netcode surface); device auto-switch (KBM/gamepad) replicated as a `byte`; strafe-while-aiming free.

 - [ ] **Base-side cohesion accents**: cyan ordered-Aether lights + perimeter relief + re-enabled tiled base ground (deferred this pass to avoid clashing with the tuned SSAO/ACES look — the Blightfield got the dressing budget).
 - [ ] **Clearing as a spatial mechanic**: shipped as juice + scrap only; make cleared cells buildable / reveal hidden nodes (the "functional gating" fork from the intake gate).
-- [ ] **Build-palette HUD + ghost-preview**: dedicated V/N keys for now; a selectable palette + placement preview is the UX follow-up.

 - [ ] **Per-`Variant` clutter meshes**: `BlightClutter.Variant` is replicated + round-robined but the prefab is single-mesh; swap per-variant meshes (additive, no schema change).
 - [x] **Focused-editor validation** (2026-06-04): confirmed in Play — Wall **stops the player CC at the collider face** (X 2.50→3.257, server==client); Blightfield **reads orange-wild rock basin** vs cyan base (real player-view shots); **clutter-clear loop** deposits Biomass + shatters + replicates (BIO 0→10, clutter 14→13); node harvest works (AETHER 0→30).
