Walkthrough

GitHub Actions runner selectors are changed from self-hosted ARM64 labels to ubuntu-latest for the ARM64 backend image build and six CI jobs.

Changes

GitHub Actions runner migration

Layer / File(s)	Summary
Image build runner selection `.github/workflows/build-multiarch.yml`	The ARM64 `backend` matrix entry now uses `ubuntu-latest`.
CI job runner selection `.github/workflows/test-ci.yml`	The `build-images`, `test-suite`, end-to-end, and test jobs now use `ubuntu-latest` runners.

91-91: 🩺 Stability & Availability | 🟠 Major

Add ARM64 emulation or use a native ARM64 runner.

ubuntu-latest selects an x64 runner, while this matrix entry builds linux/arm64. The job only configures Buildx and does not install QEMU/binfmt, so Dockerfile.backend builds that execute target-architecture commands can fail. GitHub documents ubuntu-24.04-arm for native ARM64 jobs, and Docker’s Buildx workflow uses setup-qemu-action to support additional platforms. (docs.github.com)

Add docker/setup-qemu-action@v3 before Buildx for ARM64 entries, or change this selector to a native ARM64 runner.

The move to ubuntu-latest runners (#2081) dropped available disk from the ~40GB self-hosted runners to ~14GB, so `docker load` of all four OpenRAG images ran out of space unpacking OpenSearch ("no space left on device"). Add a step to build-images, test-suite, and e2e-run that removes the large preinstalled toolchains these jobs never use (Android SDK, .NET, GHC, CodeQL), reclaiming ~25GB before any image build/load. Co-authored-by: Cursor <cursoragent@cursor.com>

The image cache key used only runner.os (always "Linux") plus a source hash, with no CPU arch. After the ubuntu-latest migration (#2081) the amd64 build-images job hit the cache from earlier arm64 self-hosted runs and restored/re-tagged stale arm64 images, shipping arm64 images to the amd64 test jobs (caught by the arch guard as a host/image mismatch). Add runner.arch to every image cache key so amd64 and arm64 caches never collide, forcing a native rebuild per architecture. Co-authored-by: Cursor <cursoragent@cursor.com>

…aS) (#2051) * feat: add preview-mode ingest backend with live index proof (OSS + SaaS) Introduce preview ingest plumbing so the frontend can show ingest progress and verify indexed chunks without persisting Docling layout JSON. - Add preview=true on upload router and connector sync (enabled in OSS and SaaS via is_ingest_preview_enabled; disabled on_prem) - Thread preview_mode through UploadTask, task service, and connector sync - Keep completed files in /tasks/enhanced for preview tasks (multi-file carousel) - Add GET /ingest/preview/{task_id}/index-proof to query OpenSearch live for chunk metadata (phase, text previews, embedding model/dimensions) - Track document_id on FileTask for index-proof lookups (set in Langflow and connector processors before ingest) - Wire IngestPreviewService as a stateless helper (no in-memory Docling cache) Intentionally excludes the spike's /docling endpoint and preview-only Docling options (embedded page images). Layout skeleton stays frontend-only; backend serves task phase + index proof only. Tests: API guards, index proof service, router preview threading, enhanced task serialization for preview vs normal tasks. * Address code-review findings on the preview ingest backend: - Pass the validated upload_task into IngestPreviewService instead of re-fetching from TaskService (closes preview_mode TOCTOU gap) - Add service-level preview_mode guard and map not_preview_task to 404 - Gate index-proof endpoint with require_permission(knowledge:upload) - Return per-request JSONResponse instances (no shared response object) - Sort chunks by page + numeric suffix instead of lexicographic _id - Use OpenSearch hits.total for chunk_count; expose chunks_returned and chunks_truncated when the 200-chunk cap applies - Return file_not_found (404) for unknown ?file= paths in multi-file tasks - Update Langflow processor comment for document_id threading - Expand unit tests: single-fetch regression, ordering, totals, file_not_found, document_id threading, and non-preview rejection * fix lint ruff * adding a feature of flag * address minor issues raised by Mike P * style: ruff autofix (auto) * ci: fail fast on runner/image architecture mismatch in integration suite * ci: free up runner disk space before building/loading images The move to ubuntu-latest runners (#2081) dropped available disk from the ~40GB self-hosted runners to ~14GB, so `docker load` of all four OpenRAG images ran out of space unpacking OpenSearch ("no space left on device"). Add a step to build-images, test-suite, and e2e-run that removes the large preinstalled toolchains these jobs never use (Android SDK, .NET, GHC, CodeQL), reclaiming ~25GB before any image build/load. Co-authored-by: Cursor <cursoragent@cursor.com> * ci: scope image cache keys by runner architecture The image cache key used only runner.os (always "Linux") plus a source hash, with no CPU arch. After the ubuntu-latest migration (#2081) the amd64 build-images job hit the cache from earlier arm64 self-hosted runs and restored/re-tagged stale arm64 images, shipping arm64 images to the amd64 test jobs (caught by the arch guard as a host/image mismatch). Add runner.arch to every image cache key so amd64 and arm64 caches never collide, forcing a native rebuild per architecture. Co-authored-by: Cursor <cursoragent@cursor.com> * ci: relocate Docker data-root to /mnt to fix disk exhaustion Trimming preinstalled toolchains alone did not free enough space on the small ubuntu-latest root filesystem (~30GB), so `docker load` of all four OpenRAG images still hit "no space left on device". Move Docker's data-root onto the runner's large ephemeral /mnt disk (~70GB) before building/loading images, and additionally clear swift/powershell caches and apt lists. Co-authored-by: Cursor <cursoragent@cursor.com> * fix: forward explicit preview flag from v1 ingest endpoint The public /v1/documents ingest endpoint calls upload_ingest_router directly (not through FastAPI form parsing), so Form-defaulted params must be passed explicitly. The new preview param was omitted, leaking the Form("false") sentinel into `preview.lower()` and raising AttributeError -> HTTP 500 on every SDK ingest/delete/filter call (18 sdk-python + 6 sdk-typescript failures). Pass preview="false" (preview is frontend-only; v1 SDK does not expose it) and add a regression test asserting the flag is forwarded as a string. Co-authored-by: Cursor <cursoragent@cursor.com> * revert: drop CI runner/disk/cache workflow changes Revert the arch-mismatch guard, disk cleanup, arch-scoped image cache keys, and Docker data-root relocation added in this branch. The underlying CI infrastructure issues were fixed separately in another PR, so restore scripts/ci/run_integration_suite.sh and .github/workflows/test-ci.yml to their pre-change state. Keeps the v1 preview ingest code fix.
