The fix landed as #2698 (9dfc91e0) with its parity evidence, but no
progress-doc record did: add the status line and progress-log entry in
ROADMAP.md, the status line, revision row and M8 milestone note in
docs/roadmap.md, and gap 6's evidence and revision history in
docs/gaps.md — the wrong-result backlog the issue belongs to.
Estimates unchanged.
Notes and file attachments are saved with the NoRotate flag (/F bit 5),
but nothing honoured it: on a page with /Rotate the icon was fitted to
/Rect and turned with the page, and sat away from where it was placed.
The vendored renderer now honours NoRotate (hayro-interpret patch 37):
the appearance fitted to /Rect is turned against the page's rotation
about the rectangle's upper-left corner, which stays put (ISO 32000-2
12.5.3). Form fields and links stay in /Rect, where their click targets
come from. A counterrotated appearance, as stamps use, would be turned
twice by viewers that honour the flag.
Annotation::shown_rect gives the box the note is drawn in. The UI uses
it for hit-testing, outlines, moving, the hover pop-up, the Comments
panel flash and the edit composer; a resize maps it back to /Rect.
comment_add anchors an icon's displayed top-left at `at`, and
comment_list, doc_info and comment_edit use the drawn box.
This also covers the sticky-note part of #1869.
Observed in Acrobat Pro on the public ISCIII form: the once-only page keeps
its place when printing (7 pages with nothing typed) but is printed blank.
PdfCraft draws its content, and has no relevant attribute or print-off
layer yet; the note says so.
A page area with <occur min="1" max="1"> that the body never reached was
never laid out, so the public ISCIII form lost the page that holds its
finishing instructions and the TERMINAR MEMORIA button once the repeated
copies over the body pages were removed.
PageArea records occur min (0 without an <occur>). When the body has been
laid out, an area used fewer times than its minimum gets the pages it still
needs, in template order, after the body's pages. The form is 7 pages with
the once-only page last, which is what Acrobat Pro shows.
Save is chosen when the prompt opens, so Enter saves as before. The arrow keys
and Tab / Shift+Tab move the choice between Don't save, Cancel and Save, shown
with a focus ring; Enter or Space press the chosen button, Escape cancels.
Before, Enter always saved, even with another button reached by Tab.

Optimize decoded DCT images with the generic JPEG decoder, which converts
three components from YCbCr to RGB whenever the JPEG itself doesn't say
otherwise, and then dropped /DecodeParms. An RGB JPEG stored untransformed
(/ColorTransform 0 and no Adobe marker) therefore came out in other colours
when recompressed, resampled or merged from strips.
The samples are now read with the colour transform ISO 32000-2 §7.4.8
gives them: an Adobe APP14 marker's flag, else /ColorTransform (default 1).
Untransformed samples are taken as stored, and the result is written as a
plain YCbCr JPEG (or Flate), which needs no /DecodeParms. When the marker
and /ColorTransform disagree, a value is out of range, the parameters are
not paired with the filter as §7.4 pairs them, or the decoder reads the
components otherwise (named R, G and B), the image is left as it is.
The tests draw each image with PdfCraft's renderer before and after
Optimize: RGB JPEGs with and without an Adobe marker under each
/ColorTransform, CMYK JPEGs (still left alone) and JPEG strips merged into
one picture.

Add Background draws behind the page content, so on a page that first
fills itself with opaque white (browsers' Save as PDF, print drivers) the
background was hidden completely and the tool looked broken.
- pdfcraft-edit: new `backdrop` module. A strictly detected backdrop (one
axis-aligned `re`, opaque white in a device colour space, painted before
anything else and covering the crop box) is replaced by turning that one
fill into `n` in a per-page copy of its stream; the original stream is
left untouched for other pages. Remove background restores it, unless
the copy was edited since. Page-sized pictures (scans) are reported only.
- Background gains `replace_backdrop` (default on); the default colour is
a visible light yellow instead of near-white.
- Dialog: offers to replace the backdrop, warns about scanned pages,
checks pages a few per frame, preview draws text over the colour.
- Automation: `doc_background` takes `replace_backdrop`; new read-only
`doc_backdrops` lists pages with a backdrop.
Acrobat's behaviour on such pages is unobserved; recorded as our choice
in parity/.
