fix: bound the density grid, and make [notrace] a reading instead of a flood
The plotter caps a density grid at kDensityCellCap now (deps/plotter), so a 2 s window with persistence on no longer scales the image with the window: the probe's four one-signal rows read 1 044 714 cells / 4 178 856 bytes where they read 2 226 150 / 8 904 600, and a moved frame uploads 1 044 714 bytes where it uploaded 2 226 150. The probe's own legs are unchanged (on peak=1.0000, step-acquisitions peak=1.5000, step-time ratio=0.367879). The paint probe no longer counts a frame the density is drawing as *traceless*. `Renderer::draw_traces()` returns while the ink is the image, so every frame of a persistence display stages no trace: the dump read `traceless paints: 653 (637 after the first bind)` for a run whose real figure is 4 (0), and the `[notrace]` line printed for each of those frames. It is now behind UDPSCOPE_PROBE_NOTRACE -- a per-paint line is a log flood and not a reading -- while the counters it details stay in every build, and the line stays reachable for the state it was written for (a bound row that draws nothing). Docs corrected where they stated the old rule: the README, the trigger invariants, the density probe's readings, the verification list (the new variable) and the manual page behind the panel's tooltip. |

fix: persistence is the trace's own phosphor, not a density behind a stroke
The plotter now deposits every acquisition -- the newest included -- into one grid per trace and
draws no solid trace over it, each grid in that trace's colour and with a one-sweep ceiling (its own
commit, **1b8b55d**). This side needed almost no change of its own, because the colour was already
the trace's and the trace's colour is `RowSet::signal_color()` -- the invariants' one route -- but the
figures it reads back are now per trace:
- **The ceiling is left at the library's default of one sweep**, no longer derived from the fade.
Deriving it from the steady state is the gain offset the user reported between the latest
acquisition and the persistent image; a signal crossing the same place every acquisition now settles
at the trace's colour, at full strength, and the newest sweep reads as the trace it is a picture of.
- **`cells`/`grid_bytes` are the sum over the row's traces** -- one grid each, a trace with no series
holding none -- and both the probe and the exit dump carry `traces=` beside `rows=`. That is what
makes the per-signal memory figure read: **556 537 cells and 2.2 MB per signal**, at 8904600 bytes
over the four one-signal rows of the probe's run.
The probes, re-read on this build (the `verification.md` command, `--rate 500000 --batch 1000`):
[density-probe] off enabled=0 ... rows=0 traces=0 cells=0 ink=0.0 peak=0.0000
[density-probe] on enabled=1 ... rows=4 traces=4 cells=2226150 ink=226786.0 peak=1.0000
[density-probe] step-acquisitions ... peak=1.5000
[density-probe] time-before ... peak=2.1359
[density-probe] step-time ... ratio=0.367879
[density-probe] frame cost: tick 0.62 -> 6.96 ms (184/23 frames), draw 2.02 -> 6.16 ms (177/18)
[udpscope] density: frames=748 rows=4 traces=4 cells=2226150 grid_bytes=8904600 ink=489400.2 peak=2.2 upload_bytes=2226150
`on` `peak=1.0000`, `step-acquisitions` `peak=1.5000` and `step-time` `ratio=0.367879` are the legs
that were expected, unchanged; the *draw* mean is now **below** the run before the split (2.02 -> 6.16
against 2.09 -> 20.91), because the solid traces are no longer drawn over the image.
Docs updated with it: the trigger manual page (`persistence` is the trace, one image per signal, the
newest included), the README's persistence section, `invariants-trigger-and-pinning.md` (five rules,
the ceiling and the no-stroke rule among them), `verification.md` and `probe-readings.md` (the lines
above), the trigger panel's comment and tooltips, and the plotter submodule.
`cmake --build build --clean-first -j4`: **0 errors, the documented three warnings** (two
`MathNode::source`, one `-Woverlength-strings` at 12352); `make -C build test-ui` **13 ok**;
`make -C build test-help` **green** (15 pages); the self-check **0 `Gtk-WARNING`/`Gtk-CRITICAL`** and
`gtk warnings: 0`, two `buffer allocated:` lines.

trigger: a phosphor persistence, driven by the plotter's density image
The trigger pane gains the display the user asked for and the library now provides, and the
persistence it already had is renamed to what it is.
**Persistence is one image; the last-N-traces display is "multiple events".** Both live in a new
`Advanced` expander in the trigger panel, together with the settings that are set up once and left
alone. `persistence` (a switch) turns on the plotter's `Plot::set_density()` for every row:
every triggered acquisition is accumulated into a screen-sized intensity grid drawn behind the
traces, brightness being how many acquisitions covered a cell -- no depth to choose, no memory
that grows with the acquisitions (2.2 MB over four 573x412 rows in the probe's run). `fades by`
picks the fade the user asked for: **acquisitions** (each keeps a factor of what was before it,
0.5 by default -- the phosphor afterglow) or **time** (a time constant in stream seconds, so the
display fades while you watch whatever the trigger rate).
- **Trigger mode only, as asked.** `apply_density()` (the tick) states the display on for `Held`
and `Capturing` and off for `Live`, `Waiting`, `Paused` and a file, and turning it off drops the
grid at once rather than at an acquisition a quiet trigger never sends. It is unpickable and
reserves no layout space, exactly as the invalid-span bands are: a density can never be in the
way of a cursor or a drop, and it cannot move the framing.
- **One deposit per acquisition, one frame after the frame that frames it.** `Plot::accumulate_density()`
deposits what the plot holds through the transforms of its *last* layout -- the frame's own is
computed inside the paint that follows the tick -- so `density_pending` is set beside
`record_pending` and consumed by the next tick. In the same tick it was right on a Held-to-Held
transition and wrong on the first latch, whose axis was still the live ring's. Switching the
display on under an acquisition already on screen deposits it too, so the switch does not appear
to do nothing until the next latch (`single` mode may never send one).
- **The session carries it**: `trigger_density`, `trigger_density_decay` ("acquisitions"/"time",
the words the panel shows), `trigger_density_tau` and `trigger_density_factor`, written whether
or not it is on -- and `trigger_persistence` still means the multiple-event depth, so an older
file is unchanged.
- **The library changed twice under this**: the deposit now counts a cell **once per trace per
sweep** (counting the hits put one dense sweep at the ceiling of the brightness scale and hid the
sweeps behind it -- the probe's `on` leg read `peak=18` for a single sweep and reads `peak=1`
now), and a frame's upload is every row's rather than the last row's. Both are in the plotter's
own commit.
`UDPSCOPE_PROBE_DENSITY_MS` reads it all back off the plots -- the plotter's own `ink()`/`peak()` --
with the panel's own widgets driving the switch and the fade, in four legs: **off** (`rows=0
ink=0.0 peak=0.0000`), **on** (`rows=4`, `peak=1.0000`), **step-acquisitions** (`peak=1.0000 ->
1.5000`, the factor then the new sweep) and **step-time** (`ratio=0.367879`, `1/e` for `dt = tau`).
It also reads the frame cost as an A/B **inside one run** (the accumulators at the switch against
the frames after it): `tick 0.74 -> 9.99 ms`, `draw 2.09 -> 20.91 ms` at four rows and 2.2 M cells
on llvmpipe.
Acceptance: clean build 0 errors and exactly the three documented warnings (12352-byte GResource
blob, two `MathNode::source`), `test-ui` 13/13, `test-help` green, a plain run with **0
Gtk-CRITICAL / Gtk-WARNING** and `gtk warnings: 0`, and the panel's own frame reading
`boxes=16 controls_inside=15/15 advanced_widgets=5/5 advanced_inside=5/5` (the block's controls
counted from the expander's child, which is not in the widget-parent chain -- and the search
block's walk now names *its* expander instead of "the first one", which the second expander would
have stolen).
Docs: the trigger/pinning invariants carry the rule and its five consequences, `probe-readings.md`
the four legs and the dump line, `verification.md` the probe's sequence and assertions, and the
manual's trigger page explains both displays to a user.

trigger: a phosphor display keeps the last N acquisitions; and a Force button
Two changes in the trigger pane, landed together. **Persistence.** Trigger mode keeps the last N published acquisitions and draws them fading toward the background, N being a panel control (1..8, default 1) with N=1 meaning today's behaviour exactly, so the knob is the switch. The layers are the accumulate path's own -- one layer per (signal, age) in the row's free trace slots, named with the accumulate vocabulary so `layer_base_name()` strips the suffix and `signal_color()` resolves the base signal -- so a layer is not a signal: the signal list, the colours and the measurements see one row per signal. `ScopeModel` retains the outgoing snapshot in seven atomic `shared_ptr` slots (no lock, no copy; the snapshot already exists) and a layer's channel is resolved **by name inside the snapshot**, because the channel list is renumbered by any structural change since that acquisition was cut. `RowSet::sync_layers()` re-plans from the rows and the depth alone, so a latch costs no rebuild, and `event_data_window()` skips layer slots so an older acquisition can never re-pin the axis. The schedule is 0.5^age -- the acquisition on screen at full brightness and each older one half the previous, independent of N, so raising the depth adds dimmer acquisitions rather than rescaling the ones already on screen. Memory is bounded by the ring's own `--buffer-mb` rather than by the depth, which is the bound that cannot be driven into an OOM, and the panel says when either bound bites. This also wired up `set_trace_alpha()`, which the accumulate path was setting and nothing was reading -- so the documented 0.35 translucency of an accumulation was opaque in fact. **Force.** In the trigger pane beside Arm/Disarm, shown only while trigger mode is on: one acquisition now, with the configured window. It is a synthetic edge rather than a second publisher -- the engine opens one capture at the present moment and everything else is the ordinary latch, so a forced acquisition is cut, pinned, framed, recorded and cached exactly like a latched one, and the button owns no window and no publish. The pre-trigger gate is deliberately skipped (capture now is a request for the history that exists, and the snapshot reports its own shorter pre_s), a capture already filling is refused rather than restarted, and the state afterwards is the mode's: Normal stays armed, Single disarms. The request is one atomic flag written under the model mutex with `armed` -- the producer reads `armed` at the top of a packet and the request at the bottom, so a request written between the two would be dropped -- and consumed at the end of a packet, after the channel loop and before the pending publish. **A defect fixed in passing, in the function Force was modelled on:** `on_arm_clicked()` passed `TriggerConfig::channel` (an index into `channels()`) to `set_signal_enabled()` (an index into `signals()`). With one signal acquired, arming switched on the stream's clock signal and left the watched signal untouched -- and since a signal the panel was not showing is a change, it rebuilt the buffer under the click, dropping the very pre-trigger window the arming, and now the Force, was about to capture. Measured before: `0.0100 s of history behind it`; after: `2.5299 s`. `trigger_signal_index()` is now the one resolution, used by both buttons. |

help: a tinier (i), hints beside their controls, and the tour starting in the chooser
The contextual help becomes the affordance the ask names: a plain (i) (`dialog-information-symbolic`) at **16x16**, and one that sits beside the control it explains rather than only in a pane's heading. - The mark: `GtkMenuButton` ignores `min-width` on the widget and a size request, so the size is made in `install_css()` on all three nodes (outer `menubutton`, its `button` subnode, the glyph). Measured 16x16 against the default 34x34; the dump prints it as `hint=WxH`, measured with `gtk_widget_compute_bounds()` on the first *visible* hint. - More sites: `events_record` (the "record events" switch in the trigger panel), `trigger_advanced` (the pre-trigger share row), `signals_config` (the signals pane's hint line, wrapped in a box so a hint can join it). Hints join as siblings, so none can cover a switch, pencil or dropdown. - The source chooser gets its own layer -- `chooser_sources` (a new heading above the saved-source list) and `chooser_waveform` (the waveforms action row) -- built with the one `context_help_button()` both windows use and re-synced by its Help menu's toggle. The form's `AdwEntryRow`s cannot host a sibling hint, so none is invented for the host/port fields. - The tour is one implementation over two windows: `ui_impl::TourView` plus a list of `TourStop`s; each window keeps its own table. A walk that passes its last stop calls `on_done`, and the chooser's sets `Config::tour_pending`, so a first run is one tour that crosses from the chooser into the app. The chooser's tour auto-starts from `settings.tour_seen` exactly as the window's does, and its "Guided tour" row now starts *it* instead of only requesting the window's. - Probes: `UDPSCOPE_PROBE_CHOOSER_TOUR=1` / `UDPSCOPE_PROBE_CHOOSER_TOUR_MS`, the hint size in the `help layer:`/`[helpui] contextual on:` lines, and the chooser's hints in its `chooser ui:` line. Docs updated in invariants-gtk-and-chrome.md, probe-readings.md and verification.md. |

feat: the help is a submenu, with a contextual-help layer and a guided tour
The hamburger menu's help rows were three flat entries and a window. They are a **`Help` submenu** now, which is where every GNOME menu keeps them, with the four things a first run cannot find: - Keyboard shortcuts Ctrl+/ (the existing overview, `show_shortcuts()`) - Documentation F1 (the existing manual, `show_help()`) - Guided tour Ctrl+T (new) - Enable contextual help (new, a stateful row: its check *is* the setting) The submenu *replaces* the menu's rows rather than floating beside them, the same shape and the same reason as the plot's right-click menu: a submenu torn out of the menu it belongs to is a second thing to dismiss, and the `GtkMenuButton` that owned one toggled itself out of sync the moment anything else closed its popover. It is the pages of a `GtkStack`, not a rebuild of the box and not a swap of the popover's child: the main view holds `app.layout_toggle`, which the tick's `sync_layout_editor()` and the `L` accel read, so rebuilding would leave that pointer on a destroyed widget, and a swapped child would leave the view that is not showing without an owner. **The contextual help is one table and a "?" per surface** (`src/ui_context_help.cpp`): the plot, the trigger, the cursors, the measurements, the math channels, the signals, the event history, the time window, the status line, and the math editor's identity row. Each row names the *heading box* its button joins -- a sibling of the title, never an overlay child on a corner, which is what would cover the switch or the [edit] button already there -- so adding a surface is a row and a widget pointer. Off means *gone*, not greyed: the buttons are removed, and they are found by a data key rather than a list of pointers because the math editor's heading is built afresh on every opening and a list would go stale one dialog later. `contextual_help` and `tour_seen` are keys of `settings.toml`, written through the same `Settings`/`load_settings()`/`save_settings()` the Preferences dialog uses, whose own rows start from `load_settings()` and so carry them through untouched. **The guided tour is five steps on a `GtkOverlay`** above the window's content: the plot, the side panel, the trigger, the signals and the status line. There is no popover in it and therefore no pointer grab to leak -- four dim rectangles around the hole are what make it modal -- and the probe asserts that as a reading (`controllers=` against the count taken before it opened) rather than as a claim. Everything is placed from `gtk_widget_compute_bounds()` re-read on every frame, because a widget's allocation is 0 on the frame it is first shown and a window resize moves it under a one-shot measurement; the hole is kept from the last frame that could measure the target, because a frame that lands between two layout passes would otherwise empty it and make the spotlight jump. `Skip`, `Finish` and `Escape` all hide every child and leave nothing behind. A first run gets the tour once, decided by `tour_seen` and not by "the settings file did not exist" (a user who changed the theme has a file and has still never seen it), and the flag is written when the tour *starts* rather than when it finishes: a user who skips it in the first second has still seen it. `UDPSCOPE_PROBE_HELPUI_MS` drives all of it -- the auto-start, the menu's seven rows and the submenu's five, the toggle's effect read as a count of affordances on either side of it, and the tour started, stepped forwards and back and dismissed -- and the exit dump gains `help layer:` and `help figures:`, the latter being the ten surfaces' window-coordinate rectangles that the manual's annotated screenshots crop their boxes from. Two of them are what the D-Bus-free headless run can still not decide, and both are limitations rather than defects: export carries no "?" (it is a menu action with no surface of its own, and a popover inside the menu's popover is the nested-popover trap the invariants already warn about), and the tour card cannot miss its target when the target is the whole content -- which is what the plot is at the window's 756 px minimum, where the split view overlays the side panel instead of putting it beside the plot. The probe prints both rectangles rather than asserting a placement, so that case reads as the geometry it is. Also fixed while it was found: `gtk_widget_measure()` includes the widget's own margins (measured: a 280 px box with `margin-start 453` reports 733), so a measure that is used to *place* the widget is a feedback loop -- that is what made the tour card walk between the corner and the target from frame to frame. |

feat: the locked trigger pane carries Arm/Disarm, and one function states both arm buttons
The compact line -- the pane's locked, "what is it set to" mode -- showed the arm state in words and gave
no way to change it, so arming from there meant unfolding the panel first, which is the thing the lock
exists to avoid. The control is built into the pane's *heading*, the row that stays on screen when the
body goes, and it is wired to the same `on_arm_clicked` the body's button uses, so both do one thing.
Its label, sensitivity and visibility are stated by `sync_arm_buttons()`, called from the four places any of
its inputs can move: the click, the mode toggle, the curator's per-tick re-read (a single-shot latch disarms
by itself) and `apply_pane_lock()`. The label comes from the producer's `trigger_armed()` atomic, the other
two from the toolbar toggle that owns `enabled`, so no caller needs the model lock. Visibility is
`enabled && locked`: with trigger mode off the line beside it already reads "stream (trigger off)" and there
is no engine to arm, and with the pane open the body's own button is the one on screen. Never both -- two
arm buttons would be two controls for one state.
Verified with the arm probe, which locks the pane the way a user does (the [edit] click):
compact arm with the trigger off: visible=0; with the trigger on and the pane locked:
visible=1 sensitive=1 width=51 label=Disarm
[udpscope] compact arm probe: locked=1 enabled=1 own=1 effective=1 width=51 panel_width=-1 label=Disarm
`panel_width=-1` is the "not both" assertion: the body's button is not on screen while the compact one is.
The width cost a defect to read. The control is created hidden and shown for the first time inside the
handler, so a same-tick `gtk_widget_get_width()` reads 0 while `gtk_widget_is_visible()` already says 1 --
and the body button's *stale* allocation (270 px, from when the body was still up) reads as a live one,
because `gtk_widget_get_visible()` is the widget's own flag and stays true under a hidden parent. The
reading is therefore taken one frame later, by a step of its own, and the control is compared with
`is_visible()`. Both defects are in the invariants, because the next control read this way will meet them.
0 Gtk-CRITICAL; clean build with the documented four warnings (the help resource re-measured); test-ui
14/14. Docs: the rule and both readings in `invariants-trigger-and-pinning.md`, the probe's entry in
`probe-readings.md`, and the user-facing sentence in `src/help/08-trigger.txt`.

fix: the overlaid sidebar steps aside for a drag, and the compact view follows the trigger
Two reports, both real, and neither was about the lock itself.
**A drag out of an overlaid sidebar had nowhere to land.** In a window too narrow to show both columns,
`AdwOverlaySplitView` puts the sidebar *on* the plot — that is what `collapsed` means — so the pointer
stays over the list and never over a drop target: a signal could be dragged but not dropped, which reads
as "dragging does not work". `row_drag_sidebar()` now hides the sidebar on `drag-begin` and restores it on
`drag-end`, and only when collapsed: side by side the plot is already visible, and hiding the list the drag
started in would be startling. The reading begins a drag through the *source* with the state forced
collapsed, the way the sidebar probe forces it:
pane drag: sidebar hidden for the drag=1 restored after it=1
**The compact view did not follow the trigger switch.** The locked line's first branch reads
`tc.enabled` — with trigger mode off it says `stream (trigger off)` and nothing else — and
`on_trigger_toggled()` never re-synced it, so the line kept saying whichever it had been. One call to
`sync_trigger_summary()` beside the switch sync. The dump's two `panes:` lines were already the test and
now pass it: with a session whose trigger is off, the line as found reads `stream (trigger off)` and the
live one reads the settings, because the exit probe turns the trigger on in between. Both reading `stream`
was the defect.
Verified: the two lines above; `panes: the same line as the probe found it: 'mode: stream (trigger off)'`
against the live `'signal: square | condition: window, rising | level: 0.3 .. 0.6 | mode: normal'`;
`make test-ui` 14 files; zero `Gtk-CRITICAL`. Docs: the `pane drag:` reading and the invariants bullet for
the overlay, and the `panes:` pair's second job — the refresh test — written down so the next reader knows
what both lines reading `stream` means.

ui: Arm is disabled with trigger mode off, and the redundant Go-live button is gone
**`Arm` is now disabled while trigger mode is off**, and labelled `Arm` again: it is the one control in that pane that is *runtime* rather than setting, so with no engine running there is nothing to arm. It is also the only thing in the body that stays disabled — the settings themselves stay editable, which is the point of the previous commit. `arm sensitive with the trigger off=0` is the reading. **`Go live (trigger off)` is deleted.** Its handler was `trigger_toggle → FALSE`, i.e. exactly the toolbar's trigger switch and the pane's own switch, which is what it was for: "the way out of trigger mode, from inside the panel that froze the view: it is the toolbar's trigger switch, so there is exactly one piece of state." With that switch now in the pane's own heading, the button was the same control drawn a third time. The status line that told users about it says "or switch the trigger off to stream" instead. The events pane's own `events_live` button is a different button on a different path — the file view restore — and is untouched. **And one silent regression this work uncovered.** The `trigger panel:` frame reading had been walking the *wrapper* box the app puts around the `.ui`'s panel (heading row + locked summary + panel) ever since the heading moved out of the file in the lock commit, so it reported `boxes=2 … search_inside=0/4` against a panel that was entirely correct. It reads `trigger_body` — the file's own panel — again, and now says so in its comment, because a reading that can silently start describing the wrong widget is the failure it exists to catch. Verified: `trigger panel: boxes=15 controls_inside=15/15 search_widgets=4/4 search_inside=4/4` (the documented shape, restored); `arm sensitive with the trigger off=0`; `trigger panel sensitive …=1`; `panes:`/`panel switches:`/`pane edits:` unchanged; `make test-ui` 14 files; zero `Gtk-CRITICAL`. |

fix: the trigger stays editable while it is off, and the locked pane says "stream"
Two things the lock got wrong, and they are the same mistake seen twice: trigger-off was treated as "the
pane is disabled".
**The configuration was unreachable exactly when it was wanted.** `on_trigger_toggled()` set the trigger
*body* insensitive with the mode — a rule carried over from the five-revealer sidebar, where a closed pane
had nothing to edit. A trigger is configured *before* it is switched on, so switching it off to change it,
or to read what it is set to, is the ordinary way to work. The body is now never disabled; only the
*cursors'* readout still is, which is the pane whose content has nothing to show with the instruments off.
**The locked pane described a trigger that was not running.** With trigger mode off the summary is one
line — `mode: stream (trigger off)` — because the four lines it used to show (signal, condition, level,
mode) describe a trigger that is not there. With the trigger on it is those four plus whatever is not at
its default (`noise band`, `HF reject`, `pre-trigger`, `hold-off`).
The reading changes with it: `trigger panel sensitive …=1` is now a **regression guard** rather than a
state — the trigger's body is always live, so a `0` there means the settings have been locked out again.
Verified in both states, from sessions whose only difference is `trigger_enabled`:
panes: trigger=locked signals=locked body_visible=0 summary='mode: stream (trigger off)'
panes: trigger=locked signals=locked body_visible=0 summary='signal: square | condition: window, rising | level: 0.3 .. 0.6 | mode: single | pre-trigger: 20 %'
trigger panel sensitive before the probe toggled it: 1
The locked trigger pane is 72 px with the trigger off and 192 px with it on. Docs: the invariants' rule
for which body is disabled and why the trigger's is not, the `summary`'s two forms with what each means,
the README's deviation note, and the second `panes:` line renamed to say what it is — the line as the
probe found it, because only a run whose *session* has the trigger off shows the stream form.

fix: the [edit] buttons' icons, and the locked pane says four lines not one
Two things the lock shipped wrong. **The "done" icon did not exist.** `emblem-ok-symbolic` is a breeze icon; Adwaita — which is what this app runs under — does not have it, so the button that leaves configuration mode drew a missing-image placeholder, i.e. nothing. Both names are now Adwaita's own: `document-edit-symbolic` (the pencil: edit) and `object-select-symbolic` (the check: done). This is exactly the silent failure `toolbar icons:` exists for, so the two `[edit]` buttons get the same treatment: `pane edits: locked=…(ok) config=…(ok)` is read by clicking into configuration mode and back, so one line carries both names and `gtk_icon_theme_has_icon()`'s verdict for each. The invariants now carry the rule, including the trap that a name found under `breeze` is not an answer. **The locked pane was too compact.** One line could not hold what a user opens the pane for, so it is now a small definition list: `signal`, `condition`, `level`, `mode` on four lines, and after that only the figures that are *not* at their defaults — `noise band`, `HF reject`, `pre-trigger`, `hold-off` — because a line reading "band 0" is a line that says nothing. The channel is resolved from the acquired channels and the condition quotes the figures its own shape reads (a width and its comparison, two levels, or a timeout), never one it ignores. The pane is ~192 px tall locked against 580 in configuration mode. One self-inflicted critical on the way: the probe read the summary with `gtk_label_get_text()`, and the container is a grid now — `Gtk-CRITICAL: assertion 'GTK_IS_LABEL (self)' failed`. The text comes from the sync that writes it instead. Verified: `pane edits: locked=document-edit-symbolic(ok) config=object-select-symbolic(ok)`; `panes: trigger=locked signals=locked body_visible=0 summary='signal: square | condition: window, falling | level: 0.3 .. 0.6 | mode: single | noise band: 0.2 | pre-trigger: 20 % | hold-off: 1000 ms'`; `make test-ui` 14 files; zero `Gtk-CRITICAL` and no missing icon. |

feat: locked panes for a returning user, and the trigger is persisted
Two panes, two modes. **Locked** is what a returning user gets: the trigger pane shows one line saying
what it is set to, the signal list shows only the signals that are on, and neither offers a control that
changes the configuration — each heading has an `[edit]` button (the Adwaita `emblem-system-symbolic`,
swapping to `emblem-ok-symbolic` in configuration mode) that flips its pane. A **first run** — no session
file for that source — never reaches `apply_layout()` and comes up in configuration mode, because
configuring the host is what a first run is for. The mode is a mode and not a setting, so it is
deliberately not persisted.
The locked signal list drops the rows of every signal that is off, which is the whole of "show active
signals": the list already filters on nothing, so the lock is one `continue`. With the rows go the acquire
tick, the overflow menu (Information, Calibrate…, Delete, rename) and the `MATH` divider's `+` — and the
colour chip stops being clickable, because choosing a colour is configuration too. Dragging a signal onto
a plot stays: that is which view shows what, not what the scope is set up to do.
**The trigger is persisted, settings and state both** — the settings *even while it is off*, which is the
point: a trigger configured once and switched off is still the trigger you come back to. `LayoutState`
gains fifteen flat `trigger_*` keys; the channel is stored by *name* (every rebuild renumbers the
channels, the model's own rule) and the two enumerations as **the words the panel's dropdowns show**,
because an index ties the file to a declaration order — the lesson `math_op_at()` already carries. The
words are shared with the panel now (`trigger_type_text()` and friends build the dropdown arrays), so the
two cannot drift.
Two ordering traps, both found by running it:
- **The channel name resolves twice over.** `rebuild_trigger_signals()` picks up
`App::pending_trigger_channel` when the stream arrives *after* the load, and `apply_trigger_layout()`
resolves it itself when the channels are already there — without the second path the name stayed
pending past the one rebuild that would have used it, and the trigger silently sat on channel 0
(`summary='pulse width · sine …'` where the session said `square`).
- **The trigger's state is applied by pressing the control, not by setting a flag**: the toggle is set
*outside* the `updating_panels` window `apply_layout()` uses, because a toggle set inside it emits
`toggled` into a handler that returns at once and nothing would happen — no arming, no events button,
no sensitivity.
Verified, in both modes and both directions:
panes: trigger=locked signals=locked body_visible=0 summary='window · square · 0.3…0.6 · 20 % pre'
panes: trigger=config signals=config body_visible=1 summary=''
signals panel: labels=2 list=1 rows=7 signals=2 math=4 divider=1
The locked trigger pane is 42 px tall against 580 unlocked. A hand-written session round-trips: every
value it named came back in the panel's own controls, `trigger=1/1` (the state arrived and the pane's
switch followed it), and the file the app wrote back carried all fifteen keys with the untouched ones at
their defaults. `[side-tab-probe] … advanced=4` on its documented recipe; `make test-ui` 14 files; zero
`Gtk-CRITICAL` and no missing icon.
Docs: the `panes:` reading with what each field means, the corrected `labels=` note (the panel's frame is
counted above the list now, because the heading sits in a heading row), the invariants for both the
persistence and the lock, the README's deviation note, and the removal of its claim that the trigger has
never been persisted — it is now, and the locked view is built from exactly that.

ui: each pane carries its own switch, the same one the header bar has
The trigger pane and the cursors pane now have a `GtkSwitch` in their heading, and it is *one control in
two places* with the header bar's button: both run the same action (`run_app_action()`), and
`sync_panel_switches()` re-reads each pair from the toolbar's state after any change, so clicking either
end moves both. A pane whose feature is off is disabled, which is exactly the state you need the switch
in, so it belongs *in* the pane rather than only in the toolbar.
Three things it needed:
- **The sensitive target moved to the pane's body.** A control inside an insensitive parent cannot be
clicked, so a switch that greyed out with its own pane could never turn it back on. `on_trigger_toggled`
and `on_cursors_toggled` now disable `trigger_body` / `cursors_body`, and so does the startup default;
the headings, with their switches, stay live.
- **The trigger's heading moved out of `trigger-panel.ui`** and is built in `build_trigger_panel()`,
which returns the heading row and the panel together. It has to be a sibling of the body for the switch
to stay usable, and keeping it in the file would have meant the file owning a widget the code must
arrange. The file's own panel is unchanged otherwise, so the `[trigger panel:]` counts still read.
- **A guard on the sync.** Setting a `GtkSwitch` emits `notify::active` for a programmatic write just as
it does for a click, so without `App::panel_switch_sync` the program's own write would come back as a
click and flip the feature again.
Readings, both directions in one line:
trigger panel sensitive before the probe toggled it: 0; … ; pane switches live while their panes are off=1
panel switches: trigger=1/1 cursors=1/1 drove_toolbar=1 (pane switch / header bar button)
`pane switches live …=1` is the design's point and is read before anything turns either pane on; `0` would
be a switch drawn, greyed and useless. The trigger pair is moved from the *toolbar* end and the cursors
pair from the *pane* end, so the line carries both halves of the sync, and `drove_toolbar=1` is the pane's
own switch having turned the cursors on with the button following. `trigger panel sensitive …=0` is the
body, not the panel.
Verified: the two lines above; `[side-tab-probe] … advanced=4`; `make test-ui` 14 files; zero
`Gtk-CRITICAL` and no missing icon. Docs: the new reading in `probe-readings.md` with what a `0` means,
the invariants bullet for the one-control-in-two-places rule and its two traps, the sidebar bullet's
sensitive target, and the README note on why the switch is in the pane.

ui: the sidebar is two tabs, and a toggle disables its pane
Replace the sidebar's five-panel scrolling column with an AdwViewStack carrying two pages — Measure (cursors + measurements) and Signals (trigger + math + channel list) — with an AdwViewSwitcher above it. The trigger and cursors toggles change from "reveal/hide my pane" to "enable/disable my feature, leaving the pane insensitive", following the disable-not-hide principle. The keys probe loses a duplicate registration that was toggling the sidebar back on before the exit probe captured its state; the exit-probe captures now read adw_overlay_split_view_get_show_ sidebar() instead of gtk_widget_get_visible(), which AdwOverlaySplitView never changes.

ui: the trigger panel offers a noise band and an HF reject
Two label-only rows in trigger-panel.ui (band_row, hf_row, after holdoff_row and before
mode_row) and the two spins the code appends into them: the band on the level spins' scale
in signal units, the HF reject at 0-1e7 Hz with 0 off. Both are published with the other
fields -- read before the model lock is taken, assigned inside it -- and both join the
value-changed loop, so editing either republishes the condition.
The rows are shown per type: the band for every type but Dropout, which is an absence a
band cannot describe, and the HF reject for all of them, since it sits before every
comparison. `sync_trigger_rows()` resolves a row as its spin's parent rather than keeping a
second handle to it: the row comes from the file and holds one child.
The exit dump counts the panel's controls, so it reads controls_inside=15/15 now -- and the
probe confirms it, along with both search readings and no Gtk-CRITICAL:
[udpscope] trigger panel: boxes=15 controls_inside=15/15 search_widgets=4/4 search_inside=4/4

ui: the trigger panel's frame is a .ui file
The panel's shape -- the heading, one labelled row per setting, the two buttons that run it, and the search block -- now lives in src/ui/trigger-panel.ui. Every control that carries a value stays in code and is appended into the file's row: a dropdown's model and a spin's range are the application's, a label is text a translator owns, so that is where the line runs. `row_for()` is `labeled_box()`'s arrangement with the labels moved into the file; the thirteen old calls to `labeled_box()` here are gone and its eleven uses elsewhere are untouched. `sync_trigger_rows()` now guards the rows it shows and hides, because a row that comes from the file can be missing rather than merely misnamed. The frame is read back by a new dump line: trigger panel: boxes=13 controls_inside=13/13 search_widgets=4/4 search_inside=4/4 where `controls_inside` is what a drifted id breaks -- a control built and never placed leaves the panel with a field missing and nothing else complaining -- and `[defaults] trigger: 0.001 0.002 0 0.001 0 50 0.01` still reads the seven spins in the same tree order, which is the check that the restructure kept the panel's contents. Two days of grief came out of one GTK fact, now in the invariants: an expander's child is not in the widget-parent chain (`gtk_widget_get_parent()` is NULL for it even after the window is presented, while `gtk_expander_get_child()` returns it), so the probe walk had to start there instead of at the panel. The throwaway program that settled it is what stopped the workaround -- a second root in the file plus a code attach -- from being the answer. |
