The device builds the schema and version replies in a fixed 512-byte
packet and drops whatever does not fit. Read strings defensively, recover
a cut-off checksum from the one local manifest matching its prefix, and
fail with a clear message when the kit list cannot be recovered.

Port the DASP transport and Sox protocol stack from sedonaOntrol Java
to Python, enabling live device editing alongside the existing offline
SAX editor. Lazy-loads components on navigation, caches them, and
subscribes to COV events for the active wiresheet.
New files: dasp.py, sox.py, device_session.py, connect_dialog.py,
live_hooks.py. Modified: app_state.py (live-mode state), main.py
(Device menu, COV polling, lazy tree expand), properties.py (Sox
write-through), sax_file.py (structural mutations route through
live_hooks), schema.py (find_manifest helper).

Right-click a component on the wiresheet or in the tree and Properties takes
over the editor pane, listing every slot the manifest declares rather than the
handful a box paints. Config slots that are not @readonly are white and
editable; everything else is grey.
Rows are built from the slot's facets, read against SedonaDoc/niagara.html:
@trueText/@falseText, @range, @precision, @unit, and @min/@max, which bound
what Save accepts. Three facets it had wrong:
- null is a value, not an absence. control::WriteFloat pairs 'in' with a
setNull action and the sample app stores val="null" on four of them, so
null now shows, parses back, and reads as @nullText where declared.
- @min/@max on a Buf count characters. TcpDevice.ipAddr is a Buf(17) with
@max 16; a longer string is refused rather than overrunning the device.
- an int's implicit range is noise. [-2147483648 - 2147483647] said no more
than "a whole number", so only byte and short print a range they did not
declare.
meta gets a row of its own: the '>>' opens its user groups as checkboxes and
its position as x and y, since typing 822411269 into a field sets neither.
Save writes only the rows that moved, as one undoable SlotValueCommand, and
refuses the lot if any row fails its range check. An edited field paints the
view in the canvas's own dirty tint, and every way of leaving asks before
discarding.
The file name on the tree's root row goes red while anything is unwritten,
counting both a dirty document and unsaved fields. Two things this needed:
the nav tree runs on its own style, because a themed Treeview's selected
foreground beats a row tag's; and the tag is added to or removed from the row
rather than recoloured, because reconfiguring a tag does not repaint rows that
are already drawn.
Also fixes a latent hazard the panel exposed: Del and Backspace are bound
application-wide, so they now stand down while a text field has focus rather
than deleting the component behind it.

Placing a palette component no longer edits <schema> straight away. The kit is
noted as pending, its manifest is compiled so the box can be painted, and the
status bar says the kit will be declared on save. The <schema> block is then
reconciled when the file is written, in the one place that can report the whole
kit list the file will carry, with each kit's version and checksum.
What a kit's manifest depends on counts as used too, transitively, so placing a
component can bring in more than one entry: hvac pulls in types, ontrolPion
pulls in ontrolPlatform.
New Kits > Manage Kits... dialog lists every kit in three groups -- needed by
the app, declared but unused, and merely installed -- with the pinned build, the
newest installed build, and an Action dropdown of every build a kit ships.
The tick means the schema declares the kit: grey and fixed for kits the app
needs, unticked to remove, ticked to add at the newest build. "Upgrade all kits
to latest version" moves every declared kit; "Update kits" applies the ticks and
the Action column, additions and removals included.
Every schema change is applied as a batch, then verified: a missing manifest or
a component type that stops resolving reverts the whole block and reports why,
and a kit the app needs cannot be removed. Changes are one undo step, which
recompiles the slot registry in both directions since a repin can change a
component's slots.

Parse the readonly facet from kit manifests and use it to disable
slots that cannot participate in a link: read-only slots are greyed
on the target side only (they remain selectable as sources), action
and void slots are greyed on both sides, and type mismatches are
greyed when the other side has a selection. A status label previews
the link path at the bottom of the dialog.

Implement full link workflow between component slots on the wiresheet:
- Link Mark / Link From / Link To context menu items for creating links
- Link dialog with slot type validation and source/target swap button
- Selectable link wires (click to highlight in red) with right-click delete
- Undo/redo support for both add and delete link operations
- Component deletion already cascades to remove related links

A kit with no manifest under the Sedona home folder called sys.exit(1),
tearing down the whole app over one unopenable file.
schema now raises MissingManifestError instead, collecting every
unresolved kit first so one dialog names them all rather than the user
fixing them one reopen at a time. describe_missing_manifests builds the
body, pointing at the configured Sedona home and at Preferences.
open_file catches it, reports it, and calls the new
reset_to_startup_state to return to the just-launched state: no file,
empty tree, empty sheet, cleared registries and undo stack. The generic
except now resets too, since a half-parsed file previously left
current_file_path and a stale root behind.
Placing a palette component hits the same loader, where a full reset
would be too destructive: it rolls back the <kit> entry it just added,
rebuilds the previous registry, and abandons only that placement.
schema no longer imports sys or tkinter, so it reports nothing itself
and stays testable without a display. base_window_title moves to
app_state so the reset can restore the title without duplicating it.
README: document the new behaviour, drop the fixed gap, and correct the
stale "no undo, no keyboard shortcuts for save" claim.
