v0.2-alpha — WebGPU + Combined Arms

223 commits since v0.1-alpha (2025-09-22) — major engine and content overhaul.

Live build: https://terror-in-the-jungle.pages.dev

Renderer

• WebGPU + TSL by default, automatic WebGL2 fallback (KONVEYER 0-10, merged 2026-05-13)
• TSL per-fragment Preetham sky with in-shader HDR sun-disc
• AGX tonemap (ACES toggleable via WorldBuilder)
• Per-scenario exposure recalibration
• Sky LUT bumped to 32×32 for fog/hemisphere reader smoothness

World

• A Shau Valley 21km real-DEM scenario
• DEM edge taper replaces boundary clamp
• Slope-aware route stamping
• Hydrology river surface + per-mode water enable

Vehicles & Combat

• M151 Jeep — drivable, full physics
• M48 Patton tank — chassis + turret + cannon, Rust→WASM ballistic solver pilot
• M2HB stationary emplacement — player + NPC gunners
• Sampan watercraft — VC/NVA river boat
• PBR (Patrol Boat River) — twin M2HB mounts, PBR-class US riverine
• M35 truck + M113 APC (motor-pool placements)
• Tank gunner AI with lead prediction + kill attribution
• NPC mount/dismount of emplacements
• NPC wade behavior + slope-stuck recovery
• Re-enabled Recast crowd surface, fixed terrain-solver stall loops (DEFEKT-4)
• Cover-search spatial grid (DEFEKT-3)

Water Physics

• Buoyancy + watercraft physics (hand-rolled hull)
• Player swimming + breath system
• River flow gameplay current pushing floating bodies
• Wade foot-splash effects

Wayfinding (2026-05-19 campaign)

• Press-F-to-board proximity HUD prompt
• Drivable-vehicle markers on minimap, full map, and compass

Architecture

• Phase F materialization rearch R1 — engine architected for 3,000 combatants via materialization tiers (live-fire verified at 120 NPCs)
• Combat sub-attribution telemetry (Influence/AI/Billboards/Effects)
• Lane rename: lodLevel → simLane + renderLane
• Sky-refresh idempotency at 2s cadence

Campaigns

• 2026-05-13 post-WebGPU campaign — 12 cycles, 66 PRs (#192-#274)
• 2026-05-19 visual-and-wayfinding campaign — 3 parallel cycles, 11 PRs (#275-#285)

Infrastructure

• Cloudflare Pages deployment (manual via workflow_dispatch)
• Mobile WebGL2 fallback validation
• bumped cloudflare/wrangler-action v3 → v4
