The reported "cannot add edges" has a specific cause: the output port's hit
radius reaches past the box it belongs to, and the press handler re-derives the
owning node with a box test, so clicking the visible dot's outer half sets
pending_out to -1 and silently disarms. Edge deletion has no code path at all.
The design replaces the two-click protocol with a drag gesture, makes the list
order the editor's own invariant via a topological re-sort rather than a rule the
user must obey, adds a view transform with every hit test routed through its
inverse, and trades the modal alert on Apply for a live validation line. It also
records that the Cancel button still calls gtk_window_destroy -- the dangling
dialog pointer CLAUDE.md documents as fixed was only fixed on the Apply path.

Two code-review findings:
1. Add a guard in cmake/install_desktop_entry.cmake that fails visibly when both
XDG_DATA_HOME and HOME are unset or empty, preventing silent installation to
the filesystem root in minimal CI sandboxes.
2. Replace the plan's tail-based verification with grep, because cmake's
FATAL_ERROR message and ninja's "build stopped" lines push the actual
rejection message out of the last four lines. The grep command reliably finds
the expected "desktop-file-validate rejected" string.

Five tasks, each ending in a commit: the two SVGs with build-time xmllint
validation, the window icon plus the registration move and the app icons:
assertion, the AdwAboutDialog migration, the opt-in desktop-entry target, and
the documentation with the full regression run.
Written assertion-first, since the project has no unit suite: each task's first
step adds the probe or dump line and watches it read MISSING. Both negative
tests are real -- one breaks an SVG comment and requires the build to fail, the
other breaks Type= and requires the target to FATAL_ERROR.
The spec asserted that a paintable's intrinsic size reads 0x0 for an SVG
librsvg refuses. It does not: gtk_icon_theme_lookup_icon() never returns NULL
and always reports the requested size, and a valid icon, a malformed one and an
absent name all snapshot to the same texture node. GMarkup accepts the double
hyphen, and gdk-pixbuf goes through glycin here and refuses our own icons.
So the malformed file is caught by preprocess="xml-stripblanks", which runs
xmllint during glib-compile-resources and fails the build with file, line and
column. The runtime line keeps its format but asserts only what it can: the
name resolves, the resource is present, and the root element declares the size.

Records the decisions taken before design — the application ID stays
org.udpscope.app, the icon is the instrument face, and the desktop entry is an
opt-in CMake target rather than an install() rule — along with the HIG
constraints the artwork is built to and the two silent failures the new
verification line has to tell apart.

Eleven tasks over the approved spec: build info and About, the plotter's
ctrl/alt axis-restricted zoom, 14 help pages, the accelerator table and
overview window, the app key controller, and the two-tier status bar.

Four features the user asked for together: an About dialog (version, build
timestamp, settings path), a shortcut overview covering the keyboard and the
mouse, a fourteen-page help window, and a status bar split into a short glance
line plus a details popover so the plot's own row stops being crowded.
Records one deviation from the approved design: keyboard zoom-x/zoom-y use
ctrl/alt rather than shift, because `+` *is* shift+`=` on the common layouts and
a bare zoom-in therefore already arrives with Shift set.

Seven tasks, each ending in a probe assertion rather than a unit test -- this
project's regression net is the headless probes, not a suite. The spec's
multicast round trip is split across three tasks so nothing in the plan needs a
group this machine can join.
Launched with no --server, udpscope silently connects to 127.0.0.1:8000 and
offers no way to pick a source or see which ones it already knows. The design
is a pre-flight dialog: it runs before ScopeModel exists, so a cancel costs no
buffer and no socket and the existing pipeline is untouched.
The list is built from the stored session files, filtered to those naming at
least one signal -- a development machine accumulates one file per probe run on
a throwaway port, 140 of them here -- and the session format gains multicast and
interface keys so a row can reconnect exactly.
