Added bounded 32-bit BMFF item-id insertion for parseable foreign item graphs
that already use iloc version 2. iloc version 0/1 targets remain on the
existing 16-bit insertion path.
Added TransferSafetyMode on TransferProfile. The default
CompatibleFile mode keeps current transfer behavior, while RenderedImage
drops source raw color calibration/correction metadata, camera raw settings
XMP, source ICC profiles, MakerNotes, and non-C2PA JUMBF data for rendered
image outputs.
Added transfer policy decisions for filtered image properties, ICC profiles,
raw color calibration, and camera raw settings.

Public BMFF writer-contract docs now state the remaining item-id-width limit
explicitly: 32-bit inserted item IDs require an existing iloc v2 graph, and
unsupported or exhausted item-id spaces fail safely instead of truncating IDs.
BMFF foreign-meta insertion keeps newly inserted metadata item records on
iloc construction method 0 with absolute file-offset extents for broad
reader compatibility.
BMFF foreign-meta insertion now compacts zero/foldable iloc base offsets
to a zero-width base-offset field when rebuilding supported item graphs,
preserving absolute self-contained item extents for simpler readers.
C++ and Python metatransfer wrappers now accept
--transfer-safety compatible|rendered.
Writer-contract docs now include a per-group transfer safety matrix for
rendered-image exports, including opaque MakerNote handling.

Fixed BMFF iinf version 1 scanning to read its 32-bit entry count, keeping
writer read-back validation aligned with version 1/2 item tables.

Added a BMFF API roundtrip test that writes Exif and XMP into an iloc v2
target with high item IDs and scans the result back as one Exif item and one
XMP item.
Added focused BMFF coverage that verifies inserted Exif/XMP item records use
construction method 0 and absolute file-offset extents.
Extended the BMFF image-usability gate with an explicit ExifTool
reader-layout regression check for transferred Exif items in HEIF/AVIF/CR3
targets.
Extended rendered-image safety coverage to require policy decisions for
image-layout fields, ICC, RAW/DNG color and correction tags, camera raw
settings XMP, opaque MakerNotes, and non-C2PA JUMBF data.
Extended the metatransfer smoke gate to verify that
--transfer-safety rendered prints user-visible policy decisions for the
same safety-filtered groups.
Extended the Python metatransfer smoke gate with the same
--transfer-safety rendered policy-output coverage.
