MSAA picking finally works**. Previously enabling `Samples > 1` broke picking entirely: the pick attachment was an MS-resolved `Rgba32f` buffer, and the `IntBitsToFloat`-encoded ids were denormals (1, 2, 3, …) which NVIDIA's MS resolve flushes to zero — every pickId came back as 0. Fixed by going to a single MS framebuffer with `Rgba32f` pick attachment, plain-float storage end-to-end (no bit-cast), and ≥2-of-8 same-id neighbour validation in a 33×33 spiral on the CPU. Silhouette pixels (which average two distinct ids into a non-integer) fail validation and the spiral moves on; interior pixels (all 4 samples agree) round-trip exactly.
`Sg.PixelSnapRadius : aval<int>`** — per-scope snap radius. Default `1` (absorbs the 1-pixel silhouette feather the validator rejects). Values are clamped to the global cap (16) at pick time. Snap walks a static disc of `(2R+1)²` offsets sorted by squared distance from center; first valid candidate wins. Pickable pixel hits and BVH-pickable ray hits compete homogeneously per offset (closer-in-depth wins).
BVH cone cull**: `BvhTree3d.GetIntersecting(hull : FastHull3d)` added. Built per-`Read` from the snap window's NDC sub-rect via `ViewProjection.toHull3d` so the spiral only ever ray-tests the small candidate set whose bounding boxes intersect the cone.
Pick attachment encoding rewritten** — all four channels are plain `float32`, never bit-cast:
Mode A: `(id, n24, depth, pi)` where `n24` is `Normal24.encode` (12+12 octahedron packed into ≤ 2²⁴, round-trips exactly through float32 mantissa).
Mode B: `(-id, pvp.x, pvp.y, pvp.z)` — direct per-component float32 storage of the user's `PickViewPosition`, no `(dir, length)` decomposition. Mode-B's surface normal is now estimated CPU-side from the same-id neighbours already gathered for validation (cross-product of the largest-area tangent pair, oriented toward camera).
Pick-effect cache prefix bumped from `fpick_` → `pickv3_` so older shader caches invalidate by name.
Id recycling**: `acquireId` / `releaseId` with `freeIds : SortedSet<int>` (smallest-first reuse). Per-`IRenderObject` `acquiredFor` tracks the multiset of scopes acquired during wrapping so a `MultiRenderObject` releases exactly N times when removed. Keeps the live id space dense well below the 2²⁴ float32 ceiling regardless of scope churn.
Hot path is allocation-free**: spiral inner loop (~805 iters per pointer move) uses mutable locals + a sentinel for "no winner yet" instead of `option<tuple>` chaining; `cullSet` pre-flattened to `CullEntry[]` (struct); `vp.Backward`, `proj.Backward`, `view.Forward/Backward` cached as locals; `PixelSnapRadius` `AVal.force`'d once per scope per `Read` via a small per-call cache; CPU normal estimation runs only after a winner is decided. Big win on the WebAssembly interpreter.
`ReadPickRegion`**: now returns `voption<PickRegion>` (raw `float32[]` + strides) for the new fast path, with the legacy closure-returning overload preserved for external callers.
