The EXR sequence writer and comp.saveFrameAsExr clamped colour to 0..1 before the sRGB decode, so a 32 bpc project lost every over-range value. The lower bound stays at 0 and alpha stays clamped. Tests cover Rgba and Rgb sequences and saveFrameAsExr.
AAC audio in an MP4/MOV whose sample rate differs from the mix rate
(a 44.1 kHz clip in the 48 kHz preview or export, or the reverse)
stuttered and sounded low-pitched in previews and in exported movies.
Cause: FilmCraft's MP4 reader, asked for audio at a rate other than
the file's, applied the edit list's priming offset (1024 samples for
AAC) twice when it resampled: each read started about 1024 source
samples early and extrapolated a ramp over its first ~940 samples
(peaks near 100 against a 0.5 tone). Export and the preview mix ask
for audio a frame or a device buffer at a time, so the ramp repeated
dozens of times a second. Same-rate reads take FilmCraft's copy path
and were exact. FilmCraft fixed this upstream in 5bf2203, 87 commits
past the pinned revision.
Fix: MediaPool reads footage audio at the source's own rate and
resamples it itself (linear, by absolute sample position, so a range
comes out the same however it is split into reads), for every
container.
Test: resampled_audio_read_in_frame_pieces_matches_ffmpeg (44.1 kHz
AAC read at 48 kHz and 48 kHz at 44.1 kHz in 29.97 fps frame pieces,
against ffmpeg's decode: max error 44 before, 0.002 after) and
movies_carry_resampled_footage_audio (a 29.97 fps comp with 44.1 kHz
AAC footage exported to MP4/AAC and MOV/PCM, decoded by ffmpeg: max
error 8.7 before, 0.03 / 0.002 after).

Render Settings: field render with 3:2 pulldown phases, effects/solo/guide
layer/color depth/frame blending/motion blur overrides, custom time sampling
(duration), storage overflow through a quota hook. Output Module: crop
(edges or region of interest), resize (presets, lock aspect, quality),
straight/premultiplied/alpha-only channels, post-render actions, include
project link, audio channels and PCM formats, WebM bitrate and key frame
interval. Render Settings / Output Module templates with built-ins and
defaults per slot (Edit > Templates dialogs), render logs next to the
output, Notify on completion. All through renderQueue.* commands and
persisted in the project.

New L3 crate effectcraft-gpu: a wgpu compute backend for the per-frame
compositing walk (layer transforms with the CPU's nearest/bilinear/bicubic
sampling and minification pre-filter, motion-blur accumulation, track
mattes, Preserve Transparency, layer style passes and knockout, all 38
blend modes as a WGSL port of color::blend, 8/16 bpc clamp+quantise,
colour-space conversions). 3D runs, adjustment and wireframe layers run on
the CPU between GPU steps. GPU effects with the CPU semantics: Gaussian,
Fast Box and Directional Blur, Glow, Levels, Curves, Hue/Saturation, Tint,
Fill, Gradient Ramp, Fractal Noise, Drop Shadow, Brightness & Contrast,
Exposure, Invert, Transform (registry gpu badge from effects::GPU_EFFECTS).
render: Backend (Cpu/Gpu/Auto) in RenderOpts, the Accelerator trait and
Renderer::accel, GPU effect chains in the effect stack, hooks for the GPU
walk. Project setting gpu_acceleration (Mercury GPU Acceleration / Software
Only), render.backend command, file.projectSettings renderer. Session and
Render Queue exports carry the accelerator. CLI --gpu and bench --gpu.
Tests compare GPU vs CPU renders (blend modes x bit depths, transforms,
masks, mattes, motion blur, colour management, styles, collapse,
adjustment fallback, every GPU effect) and skip without an adapter.

- apps/effectcraft-web (L6): eframe web runner booting the shared EffectcraftApp with a browser
session: in-memory file table, <input type=file> pickers and drag-and-drop for open/import,
downloads for Save and Render Queue outputs (several files as one stored .zip), and the
window.effectcraft promise API over the control channel. Demo project on start.
- wasm32 runtime fixes: web-time for Instant/SystemTime (render, engine, export, ui-egui);
Frames renders queued jobs on the UI thread (Frames::pump) instead of a thread pool;
Render Queue runs inline; relative outputs resolve under / ; control PNGs inline.
- effectcraft-export: per-job output Sink (files to memory instead of disk); host FileExporter
carries it; test that sink exports touch no file.
- xtask web [--dev] [--serve PORT] (wasm-bindgen 0.2.129, optional wasm-opt, COOP/COEP server);
effectcraft-web in WEB_CRATES. docs/web.md, headless Chrome smoke test, favicon (+attribution).
