The 1,457-line wire() registered every collections-sidebar and grid-drag
callback in one function, sectioned only by comment. Lift each section
into its own fn: wire_selection (split further into wire_selection and
wire_selection_filing, since the original section ran to 375 lines),
wire_drag, wire_trash, wire_trash_from_grid, wire_tree_navigation,
wire_create, wire_rename, wire_remove, wire_row_drag (the tree row's own
hold-drag, which the original "remove" comment's span covered but which
is really a separate feature), wire_row_menu, and wire_membership.
wire() itself now just coerces the shared closures to trait objects and
calls each in the original order. visible_ids is coerced to
Rc<dyn Fn() -> Vec<ImageId>> at the top, alongside on_scope_changed and
session, so the new functions take plain trait objects instead of
threading a generic parameter through every one of them.
develop.rs had grown to 9,327 lines covering everything the develop
session does: opening a photograph, the parameter-row and curve-widget
panel model, mask viewing and editing, mask creation and the rasteriser
that turns a mask stack into GPU arrays, spot repairs, scene
segmentation, framing and zoom, white-balance sampling, rendering and
film choice, and the undo/snapshot history. docs/dev/code-health.md
CH-1 names dr-ui's lack of a view layer as the reason every feature
kept landing in a handful of files; this is the first of the two pure
splits it recommends as easy, no-behaviour-change wins independent of
that larger rework.
The boundaries follow the file's own sections (several were already
marked off with comment headers) and the seams a full read turned up
underneath them -- mask storage/rasterisation turned out to be a
distinct concern from mask viewing and editing, and rows/tabs/curves
from each other, so those split further than the headers alone
suggested. Each module stays under about 1,500 lines. Struct fields
and the handful of helper methods now called from a sibling module
became `pub(super)`, which is strictly narrower than the whole-crate
reachability a single file gave them; nothing gained visibility outside
`develop`. Tests moved with the code they test, including the few
cases where a helper one file's tests needed was itself only defined
in another's -- those became shared fixtures in `mod.rs` alongside the
`headless`/`read_back`/`grey_session` helpers that already worked that
way. `mod.rs` re-exports every item `develop::` callers outside this
module used before, so lib.rs, masks_ui.rs and the rest needed no
changes.
wire() registered every settings-page callback in one 416-line function,
fenced only by section comments. Each fenced section (opening and
closing, cache, faces, export, reset) is now its own private function
that wire() calls in the same order, with the section's own comment kept
as its doc comment. on_budget_changed and on_open are coerced to trait
objects at the top of wire() so the new functions take a plain
Rc<dyn Fn> rather than needing their own generic parameter, with no
change in the closures registered or the order they are registered in.
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.
