Two live defects at cadfba0, each with the repro that showed it and the
fix that answered it: a span places the slot after a collapsed leftover
child a gap early and a gap too long, and a child reused under a parent
that redrew keeps the mask index that parent replaced, so its drawing is
clipped where the subtree used to be. Neither is covered by a test, which
is why the suite is green over both.

`docs/LAYOUT_LOG.md` existed until the one-ask protocol landed. It has, as
Iris PR #19 replacing #18, so what has to outlive the log moves into
`docs/LAYOUT.md`: the hint rule and the one ask a span makes, the reported
shares that are left and the two-answers design that would remove them, what
the fuzzers reach and what they cannot, the hypotheses not to repeat, and the
counter and dump commands with the numbers they print now. The handoff becomes
what it is for -- where the work stands, which is waiting on a review.
Measured at a888717 and at the new f6242aa on wip/hint-first, with the
inset experiment recorded as tested and rejected. The plan is now review,
render and land.
The pre-submit review of the six one-ask commits found a scroll placing
content that fits into a window-length box rather than its viewport, and
three comments still calling window lengths frame lengths.
The record's boxes are part, asked and placed, LayoutHolds carries window
ranges beside its two pins, and what is left of the layout plan is the
retained cost and the review of the branch as one diff.
Step 3 is done: against #18 the render set is byte-identical but for two
pixels of antialiasing in random and one padded block in text moving a
pixel, and a live resize of random matches a cold render at that size
exactly. The cost table is re-measured at adbedaf, where the fuzzer's own
Branch was found pinning the window and hiding what the change costs.
Step 2 of the layout plan is done in the experiment checkout, at 1512d84
and 23523ee. The handoff carries the commits and what is left; LAYOUT.md
carries the settled rule, which is now one coordinate unit with the frame
a length of it and both pins beside each other; the log carries what
implementing the plan corrected in it, including the four that would have
shipped as wrong layout and the two rig gaps that hid them.
The handoff now describes wip/one-ask at 3091fb8: a widget draws once in
the box it is asked in, its answer is placed by re-expressing the drawing,
and nothing is drawn again in a box an answer chose. The log records what
the step 3 plan got wrong -- it kept the second draw whose measurement
bit could not be defined, demanded a contract of the answer box, and
narrowed frames by region -- and what fuzzing the new protocol found: the
Part::Of composition dropping a pinned length, and a local redraw that
must be put back in the parent's answer box. The Pad frame rule is left
as a decision for Bryan with its cost stated.
