The second windows were read-only by accident: nothing accepted a drop on them, and the
signal page's *Plot on* buttons knew only the main window's rows.
- **Drop target per scope window**: the same string payload a badge drags (the signal index),
handled by `on_scope_drop_channel()` -- the target carries its own window, the row is that
window's cell under the pointer, and `assign_signal_to_scope()` lands the signal in the
window's own row set (enabling an unacquired signal first, exactly as the main drop does).
The rebuild and the area's re-point are the window's next frame in the tick: a drop arrives
from inside the very widget it rearranges, and a synchronous rebuild would reset the drag
controller under it.
- **Plot on, per window**: the signal page carries one named group per scope window ("In
\"plot 2\""), one button per plot of that window, sensitive on that window's own rows. A
window closing refreshes the pages in its destroy handler, before the deferred delete could
dangle a button's scope pointer.
- Probe: `[scope-probe]` drops through the wired handler (`drop=1 slot1='square'`) and counts
the page's groups (`page_groups=2`); the section documents that it must not run with
`UDPSCOPE_ENABLE_ALL_MS` -- the enable-all probe's second leg clears the front plot, which
is the slot this probe copies. README, help and the layout invariant follow.
The slide-over's header already prints the open page's title beside its Close button, so the
signal page's body carried the name twice and a "Back to signals" button that only repeated
navigation the header owns. Both are gone.
The header's title is now the **numbered** name -- `<n>. <name>`, `measure_channel_number()`'s
number, the same one the signal badges and the measurements pane use -- so the panel says
*which acquired channel* it is and not only what it is called. `slideover_set_title()`
retitles a page in place (the open one included): the number follows the stream's channel
numbering, and the page is refilled whenever the model's signal list changes.
Probe: `[signalpage]` reads `title='1. sine' title_ok=1` (the header text against the numbered
name) and `no_dup=1` (no "Back to signals" button and no `title-3` label in the body); the old
`back_to_list` reading is gone with the button. Help, README and the probe doc follow.
A batch of view and instrument work, with the probes and docs for each.
- **Full screen per figure row**: a toggle on each row's top-right corner, revealed by
pointer proximity (`kMaximizeRevealPx` around its placed rect, per row, read from an
overlay-level motion controller so a revealed button under the pointer cannot flicker);
the plot menu offers the same as *Full screen this figure* / *Restore the layout*. The
arrangement is saved and restored through `RowState`, so nothing plotted moves. A layout
of one figure carries no toggle.
- **Second window**: `open_scope_window()` copies a figure (cells, width shares, signals in
their colours) or opens an empty one, with its own `RowSet` and `PlotArea`; the main
window's tick binds, acquires and repaints it, mirroring the time window and pin. Entries:
the plot menu's *Open this plot in a new window* and the overflow menu's *New scope window*.
- **Layout editor from the plot**: the plot menu gains *Edit the layout...* / *Done editing
the layout*, flipping the app's one toggle.
- **Measurements gate**: `MeasureOptions::gate` restricts a measurement to the held/pause
snapshot (live falls back to the live ring), persisted with the session and shown in the
measure dialog.
- **Crosshair axis badges**: a preference (`crosshair_axis_labels`, on by default) and the
plotter's badges where the lines meet the axes, in the axes' own formats; the plot menu
and the probe read them.
- **Event cache per configuration**: `EventStore` is keyed `<source>/<configuration>/`,
`retarget_event_store()` follows every configuration switch, and a pre-configuration cache
(loose files) is adopted into the configuration's folder on first start.
- **GTK4 lifecycle**: the main window's handlers move from the non-existent `"destroy"`
signal to `close-request`; scope windows are closed with it and the application quits
explicitly (the exit run's hang). The exit probe closes with `gtk_window_close()`.
- Probes: `[maximize-probe]` (single-figure rule and the corner reveal), `[scope-probe]`,
`[split-probe]` cell crosshair leg, `[prefs-probe]` store keying, `[configs]` store key,
`[rowmenu]` layout-editor entry; docs, help pages, README and AGENT.md updated.
Also fixes a probe-only use-after-free: `toggle_maximize_figure_row` replaces the figure
object, so the area must be re-pointed (the button's path does; the probe's raw call did not).
Add cell `+` buttons (n+1 per figure row), column resize handles with
drag, and update the `x` handler to call remove_cell instead of
remove_row. Fix row_weights_ misalignment in insert_row/remove_row.
Split probe steps 9-15 exercise content movement, column drag clamp,
row-weight tracking, and sensitivity at caps.

The dock button's tooltip, the guided-tour menu row's tooltip and the m / g shortcut labels still described a side panel and tabs.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
The dock's Events block, the events slide-over page, the availability-rule deviation, the probe lines and the removal of the left pane are described; the false remembered-width claim is gone.

The dock tour stop names the Events block (one click replays, Manage opens the list) and the event-history and record hints point at the page and the dock instead of a left pane.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
The dock tour stop describes the read-only readouts and their Edit buttons, and the cursors and measures hints point to the dock copy and the pages.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Both views are written from the same variable at the same call site, so the dock cannot disagree with the full panels.

Converts every --buffer-mb / buffer_mb mention to --buffer-samples / buffer_samples,
records the unit change as a deviation (README, SPECS, CLAUDE.md), documents the
buffer: and planner: dump lines and the new Preferences row, and updates the help
pages and the help-shot script.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
--buffer-samples (k/M/G) replaces --buffer-mb: the request is rounded down to a
power of two for every signal and the shared time ring. A separate memory limit
(--memory-limit-mb, a Preferences row, default 8 GiB) halves the plan until the
real ring bytes fit and says so on stderr and in the status line. The per-source
key buffer_mb becomes buffer_samples; an old buffer_mb is ignored.

A Source pill that opens nothing (UDPS, Flat UDP, files) was noise. It is now shown only while the slide-over has a source page; the [badges] source line gains visible=.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The link state is the status bar's, so the Source badge loses its state text. The signals have no lock
(the badges and signal pages are direct manipulation), and the signals page lists only unacquired
signals and uncomputed math channels (plus the acquired ones while the badge bar has overflowed).
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Also wrap the signals page's hint line, which at 375 px minimum widened the whole slide-over panel to 376.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The per-signal page bypassed the signals lock for the acquire tick and the math
Edit/Delete buttons, and offered "Plot on r" for a plot the signal was already on.
A removed page also let another signal's page show during the close animation.

The session old-file probe and save_scheduled now discriminate, Esc is read through the real key path, the dock-section probe proves the Measure section starts out of view, and the tour's spotlight is measured independently of the helper it is drawn from. A target scrolled out of its scroller no longer leaves the previous hole standing.

The two drawn tab glyphs were judged not understandable enough; the
switcher goes to the wide policy with titles only, and the glyphs,
their gresource entries and the icon-naming code are removed.

Multicast was verified on a loopback group (239.255.42.99 on 127.0.0.1); a real network was not exercised.
