Browser media fixtures

tiny.webm is an original, silent, one-second VP8 color test pattern generated for this repository. It contains no user media and is dedicated to the public domain under CC0-1.0.

Reproduce with FFmpeg:

ffmpeg -f lavfi -i testsrc=size=32x32:rate=4:duration=1 \
  -c:v libvpx -pix_fmt yuv420p -an tiny.webm

Browser tests use the committed file; FFmpeg is not required to run them.

Local Inspect header fixtures

local-inspect/tiny.jpg (48x32) and local-inspect/tiny.webp (40x24) are original synthetic FFmpeg color test patterns, under 4 KB, dedicated to the public domain under CC0-1.0. tests/js/png-local-reader.test.js reads their dimensions with the browser header reader and tests/test_local_inspect_parity.py checks the same two files against Pillow.

Reproduce with FFmpeg:

ffmpeg -f lavfi -i testsrc=size=48x32:rate=1 -frames:v 1 -q:v 10 tiny.jpg
ffmpeg -f lavfi -i testsrc=size=40x24:rate=1 -frames:v 1 -c:v libwebp -quality 40 tiny.webp

Local Inspect video fixtures

local-inspect/core-faststart.mp4, core-moov-end.mp4, core.mov, core.m4v, core.mkv, core-tags.webm, legacy-comment.mp4 and legacy-comment.webm are 0.2-second 16x16 black clips (each under 4 KB) carrying an original synthetic ComfyUI graph in their container tags, dedicated to the public domain under CC0-1.0. The core-* files carry one tag per key as core SaveVideo/SaveWEBM write them (MP4/MOV/M4V through -movflags use_metadata_tags; Matroska upper-cases the names); core-faststart.mp4 also carries parameters and comfyassets_prompt_pairs. The legacy-comment.* files carry the old VideoHelperSuite comment JSON envelope (an ilst ©cmt atom in MP4, a COMMENT tag in WebM). video-tags-v1.json records ffprobe -show_entries format_tags -of json for each file (ffmpeg 9.0.2); tests/test_utils_video_metadata.py VideoFixtureFfprobeTests re-checks it when ffprobe is installed, and tests/js/workspace-local-video.test.js plus tests/test_local_inspect_parity.py hold the browser video reader to the same maps.

Local Inspect projection cases

local-inspect/projection-cases.json holds synthetic record sets (prompt, workflow, parameters and pair-record texts, optional record_formats, a video carrier_text and limited records) that exercise every branch of the server's inspection projection: Python's Decimal spellings and exact-construction limits, the 4300-digit integer limit, duplicate keys, NaN/Infinity, the depth-64 and node ceilings, prompt node key filtering and the carrier rule. records: null stands for an unreadable file. expect pins both graph statuses; needs names an interpreter feature a case depends on. tests/js/workspace-local-projection.test.js runs them through web/js/workspace/local-projection.mjs, and tests/test_local_inspect_parity.py asserts that its answer equals utils.inspection_response._metadata byte for byte. All texts are original synthetic content, dedicated to the public domain under CC0-1.0.

Inspection parity fixtures

inspection_parity/ holds small synthetic PNGs (f01b.png ... f24.png, each under 32 KiB) and vectors.json, used by the #240 inspection parity tests. Every graph, prompt text, model name and filename prefix in them is original synthetic content written for this repository. Nothing comes from user output. They are dedicated to the public domain under CC0-1.0.

tests/inspection_parity.py builds every fixture from code. It writes the prompt and workflow records the way core ComfyUI SaveImage does (Pillow PngInfo.add_text, compress_level=4, a 64x64 constant colour image), and splices extra raw tEXt chunks with real CRC32 for the duplicate-chunk shapes f15 and f16. The larger shapes f01, f04 and f05 are built at test time instead of committed. Reproduce the committed files with:

python3 -m tests.inspection_parity --write tests/fixtures/inspection_parity

tests/test_inspection_parity_fixtures.py compares the decoded text chunks with the builders (not bytes, because zlib output differs between platforms).

vectors.json holds an inspection and a default vector for every fixture, committed or built at test time (test-time fixtures are built into a temporary directory). inspection is the workspace inspector path, with the facts the workspace shows. default pins only the resolver's default profile, run on the role records decoded from the PNG text chunks. Ingestion's own readers are covered by their own suites. The expectations start as the observed baseline. A change that alters an outcome edits the vector in the same commit. tests/js/legacy-metadata-characterization.test.js pins what the legacy viewers show on the same files.
