Transaction Science 10ba6e9bcc wai-vector: the text layer and section 5, text and accessibility (D7-7)
graphics-vector.md section 5 (Draft): what a sink exposes to assistive
technology and to a text consumer, and how. Each text block's active set (the
effective windows of the items that draw it, merged), the projection at a
frame and the transcript as exact JSON, the text record and its digest, ruby,
purposes, writing modes and the cluster rule.

- wai-vector: src/text.rs (no_std, no dependency), the a11y and text commands,
  and vectors verify recomputing every text record.
- The corpus: a new a11y group, each payload with its text record
  (<name>.a11y.jsonl) and its digest in the expected file; canonical and
  refusal vectors for TEXT. No existing expected file changes.
- tests/text_layer.rs: each rule of section 5, with expected JSON written by
  hand from the text, each falsified once.
