…h, per-zone opt-in feather In-proc D3D11 leg of the #801/#803 backend-parity port (mirrors the VK reference, 70b7826 + b0e5889): #801 semantics: - masked_composite PS grows composite_mode (replacing the alpha_over bool): 0 = hard M-lerp (explicit authored mask), 1 = #491 premul over (implicit legacy mask), 2 = MODE_ZONES: final = twod + (1-a)*(M*weave) - M gates only the WEAVE by zone geometry; Local2D overlays composite on top by their own premultiplied alpha (a toast inside a full-window zone is no longer multiplied away; the window-edge vignette is gone). - The auto wish raster goes BINARY (M=1 per zone rect, no 16px ring): the wish is HARDWARE-only (ADR-027) and hard-edged by default (#800). - The composite mask is ALWAYS the binary zone raster - an explicit frame wish is PUBLISH-ONLY (d3d11_sync_zone_mask_to_dp unchanged), never a compositor blend gate. d3d11_update_zone_wish_state now maintains the auto raster even when an explicit wish is staged. #803 (XrDisplayZoneFeatherDXR): - New d3d11_update_zone_feather_mask: when any zone requests feather, the composite samples a separately-rastered per-zone mask (hard or inward 0->1 ramp per zone, 2px steps, ramp cap 64px then wider steps, small-zone inset clamp - the VK raster_mask_zones semantics on the ClearView idiom). The published wish stays binary regardless; raster failure falls back to the binary mask (hard edges, never a lost frame). Dirty-checked on rects + radii + dims; no zone_publish_seq bump (composite-only). Also: one-shot "D3D11 Local2D composite ... (mode=N)" log per the VK leg; shaders/masked_composite.hlsl reference caught up (it had drifted - no alpha_over field since #491). Legacy frames (cube_handle_d3d11_win, engine legacy sessions) are byte-identical by the zones_frame gate: LERP/ALPHA_OVER branches keep their exact semantics. Refs #800, #801, #803. VK reference: #801/#803 merges. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
