  • contrib/ngxshim: MIT shim for DLSS Ray Reconstruction (#870, option B) (dbccf1c22d)
  • #783: snow slopes in under a cover of ANY height at the angle of repose; the apron always reaches the toe (9b8cc37d41)
  • #946 VK snow mesh: the apron dilation converges and loads only its window, rebuilds only when needed, timed (5cbed307c3)
  • #948: Alt+Shift shortcuts stay Alt+Shift by default; opt-in relocation to Ctrl+Alt+Shift (d418c36846)
  • Merged RT shadows: no bright sun lines along normal seams / strand edges in sun shadow (trace shading-away texels, RenderVKRTShadowMergeAwayTrace) (1d6b3f7894)
  • #783: snow slopes in under a high cover at the angle of repose (no vertical walls at the cover's edge) (59d939afed)
  • VK anim: deferred table shrinks were no-ops re-requested every minute; any anim re-size re-streams the whole arena; per-avatar GPU-data loss log (f094bcacd6)
  • #902 helper bridge: retry UNAVAILABLE on a backoff, do not time FIND out before login is done, reset the attach budget when ready (15df2dc764)
  • #902 look-at sync: per-remote diagnostics, rejected-line counts, stuck-motion watchdog, bounded backlog wait (4732a06c5c)

  • #946 VK weather: VRAM tier for small cards, timed weather device waits, GPU time outside the timers (6b1a4caacc)
  • #869: the dense evaluation's sub-window starts at a random slot inside the window (an exact cell's window always starts at 0: a fixed first-c subset was biased) (d283bc6b21)

  • VK weather: snow-mesh argument buffer fill -> update WAW (sync validation): vkCmdUpdateBuffer runs in the CLEAR stage, so the barriers around it name ALL_TRANSFER, not COPY (dcd3d97bce)
  • VK streamPieces: keep last-writer-wins for overlapping geometry pieces (split into ordered copies, not a first-writer trim) (44bb42ac69)
  • #902: own head froze facing forward while another Slipstream user sent where they look (c19ad8522a)

  • #869 / #87: grainy DI shadows near moving lights, GI fireflies around lamps, sun leaking into GI bounces at grazing hits, a radiance cache that change spheres kept emptying (e8fe43fb02)
  • #87 GI: a sealed room goes dark on every material path (specular occlusion, no sky haze in GI rays, no probe rims at silhouettes, forward surfaces) + GI cost knobs (169dbaf507)
  • #869 / #87: ReSTIR DI and GI never activated -- they asked for THIS frame's TLAS before it was built (012ee032d0)

  • #783: inner apron no longer culled -- a block's position includes its apron vertices (7997577db0)
  • #783: snow sheet edges always get their skirt (no open rims); boundary strides from cuts, not slopes; debug flags failed aprons (366ca775b3)
  • CI: allowlist the Contacts floater's Ctrl+F / Ctrl+W (floater-local find and close) (21f33f2d50)
  • #87 GI: bindings 18-21 never unwritten (the projector denoiser's views stand in without the GI denoiser), WAR on the GI stats copy, a hold time for the GI resources (f09c5b8b7a)
  • #87 GI-4: world-space radiance cache for multi-bounce GI hits (RenderVKGICache, default 0) (6beb7d9345)

  • #869 Phase 5b / 5c + #85: ReSTIR DI reservoir reuse (temporal + spatial) in pass 15; the denoiser trims converged texels; debug view 7 (6e164e2ba8)
  • CANDIDATES (RenderVKReSTIRDI 1; generic-core pass 15 only -- a ReSTIR frame forces the core kernel): (b3fe2a8879)
