browser-sink §14.9: where a device has no decoder of wai.graphics.vector, a composing page presents each graphics piece's floor (graphics-vector §6.3), the piece's transcript as wai.text.zstd, as text: the blocks active at the clock's tick, in block order, each with its language, direction and writing mode. A piece presents its overlay or its floor, never both. Before presenting, the page holds the floor object to its piece: its derived_from names the piece's base (floor_base), its payload is the raw frame and no other Zstandard frame (floor_frame), its target states the transcript's length and a timebase (floor_target), and its content is a transcript in graphics-vector §5.4's one encoding (floor_transcript). A caption or a subtitle block is never presented from the floor (caption_track): the text component of its language carries it, and the text layer presents it or not as the viewer set it. A forced_narrative block is presented from the floor unless the text layer shows a cue of its language with its string at that millisecond (forced_in_cue), so the words are on the page once. The text layer presents one text component of a package, or none. wai-rs browser_sink::floor is the reference (read, present), which wai-web's compose bundle calls as TextFloor. Corpus live-conformance/browser-floor/ (49 floors, 25 presentations), written by wai_browser_floor_vectors and regenerating byte for byte on x86_64 and aarch64; tests/browser_floor.rs also reads the floors wai-pack wrote for pack-conformance/multi/multi-captions-01, and wai-web's compose::floor_tests holds them to wai-vector's transcripts. browser_floor_verify.py, the second implementation, refuses 72 mutated floors each with its defect's reason, fails 23 mutated copies of the corpus, and each of its 32 checks, dropped, is caught. compose/run.mjs gains case 10. Not here: a base that is routed and then refused when loaded still refuses the package, and the overlay path does not yet leave out caption items (graphics-vector §5.7).

# live-conformance/browser-floor — a graphics component's text floor in a page
|
|
|
|
The corpus of [`extensions/browser-sink.md`](../../extensions/browser-sink.md) §14.9: floor
|
|
objects of a graphics component ([graphics-vector](../../extensions/graphics-vector.md) §6.3),
|
|
each read or refused, and what a page presents from a floor at a tick beside the cues its text
|
|
layer presents.
|
|
|
|
| member of `vectors.json` | what each case holds, and what a conforming implementation reaches |
|
|
|---|---|
|
|
| `floors` | a floor object's `manifest` and `payload` (hexadecimal), and `base`, the content hash of its piece's base entry; the `outcome` (`read`, or `refused` with the `reason`), and for a floor that reads its `tb` and its `transcript`, the payload's content |
|
|
| `presentations` | the `floor` read (a case of `floors`, by name), a media `tick`, and the `cues` of the text component the page's text layer presents (none where it presents none), each with its `lang`, its `start` and `end` in milliseconds and its `text`; the `result`: `ms`, the tick's millisecond; `presented`, the blocks the page presents as text, in block order, each a node object with `announce`; and `withheld`, each block active at the tick that the floor does not present, with why |
|
|
|
|
Every transcript is written by the generator, and every base is named by a constant: no case
|
|
describes a programme. Each refused floor is a control of one defect in the floor `programme`.
|
|
|
|
`wai_browser_floor_vectors verify` and `tests/browser_floor.rs` check that `vectors.json`
|
|
regenerates byte for byte and that `wai-rs` reaches every outcome; the test also reads the floor
|
|
objects of [`pack-conformance/multi/multi-captions-01`](../../pack-conformance/multi/multi-captions-01/),
|
|
which `wai-pack` wrote. `../browser_floor_verify.py` is the second implementation, written from
|
|
the extension's text, sharing no code with `wai-rs`, and run as `python3 -I`: it recomputes every
|
|
case, requires every mutated copy of the corpus to fail, and drops each of its own checks in turn
|
|
and requires the corpus to catch it.
