Mask geometry is stored in source coordinates, so re-cropping tighter
never destroys a layer. It makes it invisible: the layer stays in the
panel and the sidecar, its adjustment lands on pixels nobody will see,
and nothing says so. The spec had no clause for this; FR-DEV-17 now
states it, under the ID issue #10 reserved.
dr_pipeline::orphan samples each layer's mask on a 64x64 lattice over
the source, with the gradient, radial, brush and model-raster geometry
the mask shader uses, folds the parts by their joins and inversions, and
maps the samples through the framing to see how much of the coverage
the crop keeps. `hidden_by_crop` reports the layers whose share fell
below a tenth, and only those the change newly hid, so an already
stranded layer is not announced again on every later adjustment.
Ranges follow the picture and region selections need a label map this
crate does not hold, so a layer that adds either is never reported: a
false alarm on the common path would teach the notice to be dismissed
unread.
FR-RAW-2's "without changing callers" needs a test that would fail if a
caller named the concrete decoder; passing a real RAW through rawler
cannot tell the two apart, because both routes give the same answer.
The decoder_seam tests hand a stub decoder, for a container no real
decoder reads, to the catalog scan (read_metadata_only over a folder
backend), the preview ladder (the remote two-stage fetch, an import's
thumbnail and the viewer's no-GPU fallback) and export (open_for_export,
skipped without an adapter). Each assertion is on something only the
stub produces: its camera and date, a header fetched at its 64-byte
budget rather than HEADER_BYTES, preview and sensor sizes turned by its
orientation. Switching collect_metadata or make_thumbnail back to the
free functions fails two of the three tests.
The develop test_support module is widened to the crate so the export
test shares the one headless GPU context the other tests use. The
requirements note for FR-RAW-2 now records the trait as built and the
second decoder as not.
FR-DEV-19a said a part is added to the mask or taken out of it, and
mask-editing.md listed Intersect as an M2 item with nothing built. Both
now say what shipped: the requirement names the third join and why it is
a product rather than a minimum, and how old and new sidecars read across
it; the plan marks the blend-table row built, names the tests that hold
the GPU to the definition, and splits M2 into what is done and what is
still outstanding (joining non-painted parts from the panel, per-part
distance fields, folding two layers).
docs/ had 26 developer documents flat beside the manual, and the two
audiences are very differently sized: most readers want the manual and
the gesture reference, a few want the register, the designs and the
measurements. The manual and gestures.md stay at the top; everything for
someone changing the code moves to docs/dev/, and the two documents that
name their own successors — the v0.1 milestone and the UI-refinement plan
— go to docs/dev/archive/ rather than being deleted, since both are still
cited. docs/README.md is the index, users first.
Every reference follows: code comments, Cargo manifests, the workflows,
the pre-commit hook, the bench and traceability tools (which locate the
repo root by docs/dev/requirements.md now), packaging, the Docker READMEs,
CLAUDE.md, CONTRIBUTING.md and the README. The matrix links one level
deeper and is regenerated. Links out of the moved documents into the tree
gain a level; a link checker over every Markdown file finds none broken.
