A conductor draws a junction dot at each of its bends that lies on
another conductor. It only looked at the conductors on its own two
terminals, so a bend lying on a conductor of the same potential that
shares no terminal with it got no dot. Dragging the horizontal parts of
a chain of conductors onto one line, as in the report, does exactly that.
Look at every conductor of the potential on the folio instead
(relatedPotentialConductors(false)). The folio scene uses NoIndex, so a
scene lookup at each bend scans every item and made export of the
366-conductor Polonez example 60% slower; walking the potential costs
nothing measurable there (2.08 s vs 2.11 s) or on a 153-conductor
potential (0.97 s both).
The test for one other conductor moves into bendMakesJunction(). It
also stops a point being appended once per matching segment: master drew
the dot above K2 in the fixture ten times.
Across the 23 examples (133 folios) exported to SVG, 6 dots are added,
all at T-joints that had none, and none removed.
tst_junctiondots exports fixtures/junction_dot_shared_potential.qet and
checks for both dots; it fails on master with the dot above K3 missing.

A submenu under View (Affichage > Afficher) with one tick per kind:
symbol texts, wire texts, free texts, shapes, pictures, tables and
cross-references. Unticking one hides it on every folio of every open
project; the status bar says how many kinds are hidden. Session only,
not saved in the project.
Each item is tagged with its kind by its constructor (ShownKinds::tag),
so an item created while its kind is hidden starts hidden whatever
created it. A tag rather than type(): the cross-reference under a
contact's label is a plain QGraphicsTextItem.
Items that already hide themselves (wire text switched off, one text per
potential, a cross-reference snapped elsewhere) now go through
ShownKinds::setVisible(): the kind state can only veto a show, and
apply() re-shows only what it hid itself (hidden_key), never what an
item hid. Conductor::updateTextVisibility() replaces the same visibility
rule pasted in diagrampropertiesdialog.cpp and qetscriptapi.cpp.
Hidden items are not selectable (Qt), so Select All, copy and delete
skip them. Print, PDF and image export render the scene and leave them
out; the DXF export walks items itself and skips them through
ShownKinds::isHidden(). CrossRefItem::linkedChanged() keeps following
its slaves while hidden only by kind, so its label is right when shown.
Known limitation: QGraphicsScene::itemsBoundingRect() still counts hidden
items, so Zoom to fit and borderless image export keep their space.
Verified: tst_shownkinds (12 cases, two mutation checks) and ctest 55/55;
GUI hide/show of symbol texts, wire texts (incl. one text per potential),
free texts, shapes and cross-references returns pixel-identical folios;
with nothing hidden, --export-dxf of the 24 examples is byte-identical to
master (133 files) and --export-pdf renders identically (133 pages).

A new conductor gets the default two or three straight segments, which
run through whatever symbol or wire lies between its terminals; scripts
then fix it segment by segment with moveConductorSegment().
ConductorRouter finds an orthogonal path on the folio grid that leaves
and enters each terminal in its own direction, keeps clear of every
element's rectangle, stays inside the border, and charges for bends and
for running along or crossing other wires. qet.routeConductor() and
qet.routeConductorBetween() apply it through Conductor::setPathPoints(),
which pushes the same ChangeConductorCommand a handle drag does, so the
path is saved, survives a reload, and one undo restores the default.
Where no route exists the wire keeps its path and the call says so.
qet-mcp: add_conductor takes "route": "avoid", and a route_conductor op
reroutes an existing conductor (by terminal or by uuid). The router
methods are required only by an edit that routes.

Where two wires cross without being connected, a project can now draw a
small arc (a hop) on one of them, instead of the user inserting a jump
symbol and splitting the wire. It is a project setting, off by default:
Project properties > Général > "Croisements de conducteurs", with no
hops, hops on horizontal wires, or hops on vertical wires. Choosing the
orientation rather than following drawing order keeps a project
consistent.
Only the drawing changes: no element is added and no wire is split. A
wire that ends or bends on another one is a junction and never hops,
and a crossing too close to the end of a segment for the arc to fit is
drawn plainly. PDF, SVG and image export and printing show the hops,
since they paint through Conductor::paint(); DXF export, which writes
the segments itself, does not.
The setting is saved as <wire_crossings hop="..."/> under the project
root, next to <usage>, and only when hops are on, so a project that
never used them saves exactly as before.
The geometry is in wirehops.cpp, free of any graphics item, and tested
on its own. Conductor::paintedPath() feeds it the conductors of the
folio from a snapshot of their scene points, rebuilt only when a
conductor changes shape, moves, or enters or leaves a folio; each hop
path is cached the same way. Asking the scene for the conductors in a
rect instead strokes every candidate's shape, which made a 366-wire
folio render 0.6 s slower; with the snapshot the difference is within
measurement noise.

A wire saved without a uuid got a random one on every load, never saved
(#754): it had no identity from one session to the next, so a script
could only name it as "the wire on terminal N of symbol X", and a
comparison of two versions could not tell a moved wire from a new one.
When a folio is loaded, such a wire now gets a UUID v5 derived from its
two ends -- the symbol and terminal at each, sorted so the direction it
was drawn in does not matter -- and it is written on save. Never its
place in the file or its folio's index: inserting or moving a folio, or
saving the wires in another order, does not change it. Once saved the
uuid no longer depends on the ends, so re-connecting the wire keeps it;
QETProject::derivedItemUuid() never hands out a uuid the file already
carries, so a wire later drawn on the ends it left gets another one.
Wires that have a uuid keep it; a paste still renews them.
The 24 example projects: 3,189 wires, none with a uuid before, all 3,189
after one save, none lost, no uuid used twice in any project; two saves
of the same file are identical, and a second save keeps every wire's
uuid. Discussion #1103 has the measurements behind the recipe.
tst_derivedwireuuid runs --resave on a fixture naming ends by uuid and on
examples/tremie_vibrante.qet (ends by terminal number): every wire gets a
distinct uuid, the same on every load, read back after a save, kept per
wire when a folio is inserted, the wires are reordered or a wire is drawn
the other way, and a newcomer on a re-connected wire's old ends gets
another uuid. Without this change 14 of the 18 fail; with the uuid taken
from folio index and file order instead, the folio-insert and reorder
tests fail.

Conductor::moveSegment(index, dx, dy) is the same primitive
handlerMouseMoveEvent()/handlerMouseReleaseEvent() apply on a drag --
move both axes on the target segment (each of ConductorSegment's
moveX()/moveY() silently no-ops on the wrong axis or a static,
terminal-anchored segment), recompute the path, and push one
ChangeConductorCommand undo step via the existing saveProfile().
Caught while writing the first test for it: moveSegment() never set
modified_path, so Conductor::toXml() skipped writing <segment> children
and a manually rerouted conductor silently reverted to auto-routing on
the very next save -- the change took effect in the running scene but
never reached disk. Fixed by setting the flag, the same as every other
path-modifying call site already does.
qet.conductorSegments() lists a conductor's segments (endpoints in
scene coordinates, orientation, static/movable) so a script can find
the index it wants; qet.moveConductorSegment() applies the move and
refuses a static segment or an out-of-range index.

Saving an unmodified project produced a different byte stream on
every run: QGraphicsScene::items() returns items in stacking order,
and ties between same-Z items follow the scene's internal index --
not any content-derived order -- so it isn't reproducible across
process runs. The legacy terminal-id table inherits the same
instability, since ids are assigned sequentially in element order.
Sort list_elements and list_conductors into a deterministic order
before serializing, using a key built from data that's actually
stable across loads (position), not Element::uuid()/Conductor::uuid():
for an item with no persisted uuid attribute, fromXml() invents a
fresh random one on every load, so sorting by uuid would still be
non-deterministic across process runs for any legacy file -- which
this corpus has plenty of.
Also fixes a second, related source of byte-level non-determinism
found while verifying the above: Conductor::toXml() unconditionally
wrote m_uuid back out, including the synthetic value fromXml() just
invented for a conductor with no uuid attribute in the file. Every
conductor in every example project checked has no persisted uuid at
all, so this alone meant no project with conductors could ever
resave identically, regardless of ordering. Conductor gets a
m_persist_uuid flag, false only when the uuid it's holding was
synthesized rather than loaded, so toXml() stops writing a value
that was never meant to be permanent.
Deliberately NOT applying the same uuid-persistence fix to Element:
element uuids are cross-referenced by other elements' <links_uuids>
blocks for master/slave/report linking (element.cpp, tmp_uuids_link,
matched by elmt->uuid() == stored uuid on load). Making an element's
own uuid non-persistent would silently break that match for any
linked element without one already -- a real regression, not a
theoretical one. Left as a smaller, separate residual: 1-6 elements
per project across the corpus (a few tenths of a percent) still get
a fresh uuid on each load, same class of bug, needs the link-aware
version of this fix instead of this one.
Verified against 8 example projects (the ones with conductors, plus
the two zero-conductor control cases from FINDINGS.md F002), 5
resaves each in isolated HOME/XDG environments:
- Element and conductor ORDER: 0 churning sections across the whole
corpus (previously the majority of diagrams in industrial.qet,
m_000.qet and tremie_vibrante.qet churned on every run).
- Conductor uuid VALUES: 0 churn (previously every conductor in
every project, since none have a persisted uuid).
- 6 of 8 projects are now byte-for-byte identical (md5) across all 5
runs. The remaining 2 (industrial.qet, m_000.qet) differ only in
the handful of element uuids covered by the known Element residual
above -- confirmed by checking those uuids specifically, not
inferred.
- Element/conductor counts before and after resave match exactly on
every project (no data loss from the sort).
Fixes#754.
Slice 1 of discussion #503 (from-to wiring list built on projectDataBase).
Conductor is the one item type on a diagram without a stable identity
of its own -- Element and Diagram both have a uuid, Conductor didn't.
This is the prerequisite the wiring-list tables need: a conductor
table keyed by uuid, the same way the existing element table is keyed
by Element::uuid().
- Conductor gets a QUuid m_uuid, generated in the constructor, with
uuid()/newUuid() accessors mirroring Element's exact pattern.
- toXml()/fromXml() read/write a "uuid" attribute the same way
Element already does, including the same generate-on-missing
fallback (QUuid(e.attribute("uuid", QUuid::createUuid().toString())))
for projects saved before this change.
- PasteDiagramCommand::redo() calls newUuid() on every pasted
conductor (content.conductors(), all three categories), mirroring
the existing per-element newUuid() call right above it -- otherwise
copy-paste would duplicate a conductor's uuid.
Backward compatibility: Conductor::valideXml() doesn't require the
"uuid" attribute, so old files parse unchanged. Verified by opening a
genuinely pre-uuid project (examples/industrial.qet, 150 folios, 671
conductors, legacy integer terminal1/terminal2 references with no
uuid attribute at all) -- loads and renders correctly, gets uuids
assigned on load, and those uuids are stable across a second
load/save cycle (byte-identical uuid values). Verified paste
separately: copying a selection with conductors and pasting produces
distinct new uuids for every pasted conductor, none colliding with
the originals or each other.
Fix : in old projects without the conductors formula, the conductors texts aren't loaded and displayed
Fix it in method void Conductor::refreshText()
