The summary line exists so that an empty wiring list is distinguishable
from one where every conductor was excluded, and it was reporting the wrong
number to do it. QSqlQueryModel fetches lazily, so rowCount() straight after
setQuery() returns the rows fetched so far -- 256 -- not the size of the
query. Measured with Qt's own QSQLITE driver: a 1000-row view reports 256
until the model is drained, then 1000. The test project quoted in slice 2
has 280 conductors, so this was already displaying 256 on our own data,
plausibly enough that nobody looked twice.
Drain the model before reading the count.
Also refresh the database before building the model. The dialog queries the
database rather than the diagrams, so anything not yet written through was
invisible here; with conductor text now updated on change that gap is
smaller, but a project loaded before this dialog was ever opened still
relies on the repopulate.

Slice 4 of discussion #503, on top of slice 3 (#629): the smallest
surface that makes wiring_list_view visible, plus the diagnostic the
view needs to be honest about what it is missing.
Projet > "Liste de câblage (base de données)" opens a read-only table of
wiring_list_view, headed by a line stating how many conductors are
listed and, when non-zero, how many were excluded and why.
Deliberately not another exporter. QET already ships a wiring-list CSV
export (Projet > Exporter le plan de câblage, and --export-cables) which
walks the project XML; measured on the same projects it produces a row
per conductor and resolves labels correctly when the project has them.
Adding a second, competing CSV would be worse, not better -- the
database path's value is what it unlocks (terminal plans, BOM joins),
not replacing that export.
projectDataBase::excludedConductorCount() counts, from the live scene,
the conductors deliberately absent from the conductor table because a
terminal has no uuid. Counted from the scene precisely because the
database is where those conductors are not. Verified: 671 on
examples/industrial.qet (which has 1794 terminals and no terminal uuids
at all, so its list is empty and now says so), 0 on a project whose
elements do carry terminal uuids.
KNOWN GAP, not fixed here and the reason this is opened for discussion
rather than merge: after a save/reload the component columns are blank
for slave elements. populateElementTable()/populateElementInfoTable()
only insert Simple|Terminal|Master|Thumbnail, so slave elements -- relay
contacts, i.e. a large share of real wire endpoints -- have no row in
element_info for the view to read a label from. Measured on a two-slave-
contact project after reload: element rows 0, element_info rows 0,
terminal rows 2, conductor rows 1; the wire is listed (slice 3's LEFT
JOIN keeps it) but both component names are empty, where the existing
CSV export shows K1 -> K2 for the same file.
Closing that gap means widening a filter shared with the nomenclature
and summary views, which would change what those existing, shipped
features contain. That is a maintainer decision, not one to take
unilaterally inside an additive slice.
