* feat(render-service): add PreviewGate admission control for previews Independent admission gate (global in-flight cap + per-identity cap) so synchronous previews never compete with the MP4 export queue. Release is idempotent so every route exit path can call it safely. Co-Authored-By: Claude Code <noreply@anthropic.com> * feat(render-service): add single-page preview renderer Renders a scene to a PNG via SlideCanvas + static markup using the existing Chromium executable configuration, egress policy, and semaphore infrastructure, with a deadline/AbortSignal. Co-Authored-By: Claude Code <noreply@anthropic.com> * feat(render-service): add preview config and resource pixel limits Adds previewDeadlineMs / previewMaxInFlight / previewMaxPerUser config and resource-profile viewport pixel limits for previews; declares the renderer runtime dependencies installed with the render-service container. Co-Authored-By: Claude Code <noreply@anthropic.com> * feat(render-service): add POST /preview endpoint Wires the preview endpoint: declared-size rejection, gate admission before buffering, byte-capped payload parsing, scene/stage/viewport validation, deadline/cancellation, PNG response, and 400/413/429/504/500 mapping. Fixes the render_scene_preview tool's broken link (previously 404). Co-Authored-By: Claude Code <noreply@anthropic.com> * fix preview rendering and deadlines * fix(render-service): enforce preview deadline, memory bound, and shared Chromium limit - Stalled preview uploads now observe the deadline signal, error the consumer, and cancel the reader; deadline aborts map to 504 and release the permit. - Previews retain the extraction permit through rendering so parsed payloads cannot accumulate beyond the memory admission bound. - RenderCoordinator owns a shared execution semaphore so previews and MP4 renders respect the same global Chromium concurrency limit. Co-Authored-By: Claude Code <noreply@anthropic.com> * fix(render-service): harden preview admission and rendering * docs(render-service): define the preview deployment contract * fix(render-service): enforce self-contained previews * fix(render-service): allow fragment CSS URLs in previews * fix(render-service): allow background-only previews * fix(render-service): control malformed preview rejections * style(render-service): apply prettier formatting after rebase --------- Co-authored-by: Claude Code <noreply@anthropic.com>
