feat(consume): the payload says what of the question it reached, and row 4 reads it

`coverage` carries three lists: the terms the pre-pass read the question as,
the terms no concept in the bundle answers, and the terms no delivered
excerpt answers. Without it a reader holding eight excerpts cannot tell a
bundle that ANSWERED its question from one that merely ranked something --
the two payloads have the same shape.

FACTS, AND NO VERDICT, which is a measurement and not caution. Two readings
were built and both falsified over 81 questions (16 synthetic, 65 across the
three real sets, 2026-09-20): the share of question terms a delivered
excerpt answers separates the synthetic controls at 0.33 against 0.50 and
REVERSES on real data (covered questions down to 0.27, one genuinely
uncovered question at 0.71); the share of a bundle tying the best lexical
match is ~0.00 for every real question either way. Question style dominates
the first, corpus size the second.

The one bar this repository declares is the gate's: `UNANSWERED_BAR = 2/3`
over `unanswered_in_bundle`, swept and collapsing at both ends -- at 0.50
eleven real covered questions are marked, at 0.70 the row falls to 5 of 6,
at 2/3 the row is 6 of 6 and 0 of 65 real questions are marked. The margin
is thin (0.6087 against 0.6667) and is published that way, together with
what it does not catch: r761-sk2's own known-negative sits at 0.2857.

Row 4: 3 of 6 RED -> 6 of 6 GREEN, with the 10 answered synthetic questions
held unmarked as the known-negative. The contract's SS 8 gains point 7, the
consumption skill is told to read the block, and the SS 7.4 known-positive
moves with the document (14 721/375 -> 16 389/417). Suite 2292 passed.
