* Add headless GPU backend foundation for composition and flat export (issue #8062 PR 1) * Fix headless GPU readback bounds, API compliance, and error preservation (#8062) * Fix GPU readback bounds, context thread spawn error, and test parity (#8062) * Fix BandRenderer Send bound, PNG reborrows, and clippy lints (#8062) * Fix effect shadow test construction and remove dead code wrappers (#8062) * Use short reborrows for Headless renderer without lifetime escaping (#8062) * Fix clippy collapsible_if and ensure multi-band geometry in flat export tests (#8062) * Fix automation Rect import, add renderer diagnostics, and harden flat export retries (#8062) * Fix GPU feature test APIs and native target gates * Verify unsupported GPU effects before testing band seams * Use compositor buffer ownership API after upstream memory accounting change * Update export renderer test helper for owned compositor buffers * Fix headless GPU backend review findings (#10842) - release a closed document's GPU caches through a BandRenderer hook - bound the monitored readback wait and report a stalled GPU as device loss - reject 32-bit float documents before band readback so exports fall back to CPU - keep previews at 8-bit RGBA and report the palette/Duotone renderer bypass - retain renderer diagnostics when encoding fails - strengthen renderer, save-path and GPU diagnostics tests * Add GPU close-hook and 8-bit preview regression tests (#10842) * fix(io): correct renderer binding mutability * Fix remaining headless GPU review findings (#10842) - release a document's GPU caches when file.close, file.closeAll or file.closeOthers removes it through a command - honor cancellation while band readback waits, polling in 100 ms slices - fault the device after a readback timeout so later exports skip it - report single-layer, CMYK ink-mixing, ORA and PDF CPU paths to a requested renderer - keep fallback warnings in their export instead of leaking them into the next one - requeue renderer diagnostics when a renderer-aware save's final write fails - write MCP/serve diagnostics without panicking on a broken stderr - document the actual colour-space contract and drop F32 from the GPU depth list * Use question mark for cancellable readback errors * Keep GPU export diagnostics with their attempt and stop bands on cancel Encode native .pcraft bytes before draining renderer diagnostics, and requeue export warnings when a workspace write fails, so callers still report the adapter or fallback reason with the error. Move a failed GPU attempt's queued diagnostics into its CPU retry result instead of leaving them for a later successful export to report. Stop GPU band readback at the next band after cancellation, and check the interrupt before each CpuRenderer sink delivery. Band readback uploads half-precision textures, so reject U16 alongside F32: their samples cannot survive the upload. Tighten the 8-bit CPU/GPU parity checks to 1/255. * Keep headless export warnings when a workspace write fails (#10842) A capability-scoped save encodes the export, then writes it; when the write fails, the export warnings (folded together with renderer diagnostics) were pushed back through `BandRenderer::push_diagnostic`, whose default is a no-op. A custom renderer that overrides only `drain_diagnostics` therefore lost the adapter or fallback reason that belonged with the error. Keep them in `Headless` instead and return them from the next `drain_diagnostics`, alongside the renderer's own queue. The regression uses a renderer without a `push_diagnostic` override and checks the warnings survive the failed write and drain exactly once. Also name the actual source of the depth limit in the headless GPU matrix: layer content is uploaded as half-precision textures, not band readback. * Stop CPU bands and CPU retries on cancellation (#10912) The CPU retry after a retryable GPU error composes through `FlatSource::bands`, whose shared `emit` sink did not poll the export interrupt: a cancel was only observed after the whole composite finished. Check it once per band, as `CpuRenderer` does, for both RGB and CMYK ink bands. The flat and streamed-PNG retry branches also check before starting the full CPU composite again, so a cancelled export returns `IoError::Cancelled` instead of re-rendering the document. Tests: band-sink cancellation for RGB and CMYK inks, a renderer call counter proving a second export reaches the renderer, and a pending `wait_slices` poll observing cancellation set mid-wait. * Merge origin/main into GPU foundation (#10842) * Keep GPU-path diagnostics on every failure path, honour cancel in native copy - save: export warnings of a failed local write stay in Headless pending diagnostics - render: preview fallback warnings are returned, drained, and added to the doc.render reply - io: renderer-neutral fallback wording; native single-layer copy checks cancellation per band - gpu: gate wait_slices tests off wasm32 (#10842) --------- Co-authored-by: FredApps <153173854+FredApps@users.noreply.github.com>
