Add --renderer for displays with no usable GPU; gate the header reading
GTK4 defaults to Vulkan, and an X11-forwarded display has no device to make a swapchain from; the plot is a GtkGLArea, so it then asks for a GL context that is not there either. --renderer cairo is the software preset for that display: it exports GSK_RENDERER=cairo and LIBGL_ALWAYS_SOFTWARE=1 in main() before gtk_init()/adw_init(), because both are read when the renderer and the context are created. --renderer gl is the faster choice when indirect GL works, and --renderer vulkan makes the default explicit. Nothing is exported, and GTK's own choice stands, when the option is absent. The once-a-second header line is now behind UDPSCOPE_PROBE_HEADER, following the [notrace] rule: its widths are still sampled for the exit dump, but the line is detail behind that reading rather than output every run prints. UDPSCOPE_PROBE_RENDERER prints the exported pair before GTK starts and the GskRenderer GTK actually built. README, the manual's overview and docs/claude record the two symptoms and the cure. |

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. |

perf: a measurement pane is priced by its window, and its fold is inline
A pane is recomputed over the whole visible window on a cadence, and at a 15 s window (11.8 M samples, 184 k level-0 level buckets, `--buffer-mb 4000` so the stride stays 1) that is priced per *measured channel* and per *distinct share*. Measured with the new `[levels-probe]` sweep, per recompute: one window with one level 6.58 ms, four shares 10.28 ms, sixteen shares 24.55 ms, and four measurements one share each over four channels **35.69 ms** -- against a tick mean of 1.34 ms with an empty pane and 4.58 ms with that one. That is the reported "very slow with multiple measurements": the pass runs inside `tick()`, so it is a *frame* cost, and not an ingest one -- `gaps` and `packets` stay clean even though each `MeasureWindowReader` holds the model mutex for its whole life, because a socket buffer absorbs a few tens of milliseconds of producer. The largest single term inside a pass was a call. `measure_accumulate_bucket()` folds one bucket into one level, and it is the innermost loop of a walk whose iteration count is the window's buckets *times* the pane's levels; it lived out of line in `measure.cpp`, so every one of those iterations was a cross-translation-unit call. Moving it, and the crossing state it updates, into `measure.hpp` as `inline` takes sixteen shares on one channel from 24.55 to **17.25 ms** a recompute -- with every value in the dump's `measurements:` unchanged. Two levers remain and both are measured: the fetch's three out-of-line pyramid accessors plus a 48-byte copy per bucket (3.3 ms of an 11.8 M-sample window's 11.6 ms pass) needs a combined accessor upstream, and `raw` is the *signal's* share (4.6 % on the mock's noisy channel against 0.1 % on its sine), because a level inside a bucket's own `[lo, hi]` has to be walked sample by sample. Bisected with the pane populated (the earlier bisect had it empty, which cannot see this): the parent of the recent range and HEAD read **8.29** and **7.92 ms** a recompute for the same four-type pane at the same window, and neither of the two commits between them touches `ui_measure.cpp` or `measure.cpp` at all. So the cost is the scale and not a regression, and the fix makes a pass cheaper rather than removing one -- the plot's own per-frame cost was checked the same way (four commits, equal within 3 %, and unchanged by the window, the ring size and the visible sample count). `UDPSCOPE_PROBE_LEVELS_MS` with `UDPSCOPE_PROBE_LEVELS` and `UDPSCOPE_PROBE_LEVELS_CHANNELS` is the sweep; `docs/claude/invariants-measurements.md` records the curve and the inline rule, `verification.md` and `probe-readings.md` the probe and what its numbers must read, and the README the pane's cost at this scale. |

fix: a still frame's measurements are the frame's, not the viewport's
A measurement is a statistic of the window the pane is *about*, and on a pinned view -- a held event, a paused stream, an opened file -- that is the frame, not the part of it on screen. The pane followed the viewport instead, so a wheel on a latched event moved `average` and `top`: the reported "when measuring a still frame, moving the zoom makes measurements such as average or top change". Nothing about the data had changed; the user was only looking closer. The window is `RowSet::pinned_range()` while the pin frames the view and the viewport otherwise, and the choice is made in `update_measures()` -- the call site -- rather than inside `MeasureWindowReader`, because it is *booked* as well as read: that window is what the "it moved" test compares against `App::measure_window`, so a gesture inside the pin spends no recompute either, and a reader that chose its own would leave a pinned view recomputing every gesture frame for a number that cannot change. `pinned_range()` is now the one expression of the pin's extent, shared with the framing (`hold_pinned_window()`, `fit_x()`), and the reader is handed the window instead of reading the plot. Live is unchanged: there the window really moves and the statistic follows it, and the accumulator's rule about what resets the history is about neither. `UDPSCOPE_PROBE_MEASUREPIN_MS` is the guard, three legs of before/after a gesture on the row's own axis. On a latched event zoomed to a quarter (`view=[-1..1]` -> `[-0.25..0.25]`, `pin` unchanged): `same=4/4 for_same=1 pass_delta=0`, every value bit-identical -- `average=0.000000 top=0.957975 peak to peak=2.000000 amplitude=1.915950` both sides. The same on a pause taken from it. Since the key `for=` follows `pin=` now, `[measure-trace]` gained the field, so a held run reads `for==pin` with `swin` free to sit inside it. On a live view a zoom to an eighth reads `same=0/4 for_same=0 pass_delta=3 span_after=0.125000 follows=1` with the values moving -- the case the rule must not swallow. Before the fix the same probe reads `same=1/4 for_same=0 pass_delta=1 span_after=0.500000` on the held event (`top` `0.957975` -> `0.957966`) and `same=0/4 span_after=0.125000` on the pause (`top` `0.957944` -> `0.358614`). Live reads the same either way. Also fixed, found by the pause leg: pausing while an event is *held* froze an **empty** picture. `on_pause_toggled()` read `stream_at_x0()` after setting the pause state, and that accessor follows the display -- `paused` with no pause view published yet answers `-display_epoch()`, which on a held event is 0, so the cut searched the ring at edge-relative x, found nothing, and the frame bound an empty snapshot: every measurement `--`, every ruler gone (`ev=650001` on the probe's line now, `ev=0` before). The offset and the window are read first, which is the offset the axis is actually displaying. The live case is unaffected, which is why the pause probe, which pauses a live view, never saw it. Docs corrected where they asserted the old half-truth: the invariants now separate the accumulator's rule (unchanged) from the window a value is computed over (this change), the trigger/pinning file names the pin as load-bearing for both the framing and the numbers and records the pause ordering rule, `verification.md`/`probe-readings.md` describe the new probe and `pin=`, and the README and the manual say what a still frame measures. Checked: `cmake --build build --clean-first -j4` 0 errors and the documented three warnings; `make -C build test-ui` 13 ok; `make -C build test-help` green; an exit-dump run 0 Gtk-WARNING/Gtk-CRITICAL and `gtk warnings: 0`; `[measurepin-probe]`, `[pan-probe]` (`held=1`, `allowed=1`, `limited=1`), `[pause-probe]` (`event_size` non-zero exactly while paused, `axis` inside `frozen_x`, `skips` 0 live / 30 paused), `[stats-probe]` (`dn=1` across the pause), `[zoom-probe]` (`gap_px=0.0` at every step) and `[measure-probe]` + the dump's `measures window:` (all-types run `marks_in_window=4/4`, `pin=off` live) on the fast mock. `measure cost:` is unchanged in kind: `raw=37298 (0.0%)` of `covered=121704537`, 1.04 ms a pass -- the runs that read higher are the probe's own zoomed-to-a-slice windows, where the window is legitimately shorter than a bucket. |

fix: a recompute that renumbered its ring, and readouts frozen under a zoom
Three defects, all of them a window describing data that is not there. A math edit refilled the derived ring with `clear()`, which renumbers it from 0, leaving `produced()` short by the inputs' retained base. Since `live_window_locked()` clamps against every channel's `produced()`, that one lagging channel answered `n = 0` for the live view, every pause view and every trigger capture until a whole ring of fresh data had gone by -- the reported freeze, invisible until the ring first wraps, hence its intermittence. It now restarts with `clear_to(base)`, and `ChannelBuffer::republish_from(base)` puts the published window back: `acquire()` is incremental, so a rewrite in place published nothing and the pyramid went on describing the samples the edit replaced. The trigger's channel is an index, re-resolved by name after a renumbering -- but only in `rebuild_enabled_locked()`, so a math add or delete went through `set_math_channels()` with no restore, the index was clamped to -1, and `process()` returned at once while the panel still named the channel. The restore moves into `rebuild_channels()`, which *is* the renumbering, so no caller can forget it. And `update_measures()` suppressed its "the window moved" test while an event was held -- the one mode where a gesture is the only thing that can move it. Zooming a latched event left the pane describing the whole captured event. A pinned window needs no exemption: it lands on the range it already measured and fails the 2 % test by itself. The checks that missed all three: `UDPSCOPE_PROBE_MATHWRAP_MS` edits a graph whose ring has already wrapped, which `math_probe` structurally cannot reach; `[measure-trace]` now prints the mode, the window on screen and the window the numbers describe; and the dump's `marks_in_window` counts against the window on screen instead of against the one the marks were computed over, where it was a tautology.

fix: a claimed gap must be corroborated before it is believed, and its hole must fit
The user's real host reported "connected and live" with one missing-data band over the whole window
and no trace in it. The counter is the only thing that claims a packet existed, and a reservation
was booked on its word alone: a source whose DATA counter counts samples, or frames of an inner
layer, advances by more than 1 per datagram, the client cannot check that claim (it has no clock of
its own to compare against), so it holds each packet, saturates its reorder ring, delivers it in
order and reports the skipped counters as lost. Every frame therefore reported a phantom gap, and
`reserve_hole()` wrote `lost * batch_` NaN samples with no bound but the 256-PACKET cap -- the
sample form of that rule ("the number to weigh against the ring is 256 * batch_, not the 256") was
never implemented. With relative time on -- which that session carries -- each phantom gap is
materialised as NaN slots by construction: the window filled with reservations, there was never
anything missing to repair them, and the gaps also stretched the relative clock, which is why the
status bar read live at ten times the true rate.
`Acquisition::gap_plausible()` now gates every reservation on two independent tests: the arrival
clock must corroborate the claim (that many missing packets would take that many frame intervals;
deliberately permissive, because a false refusal costs a shading and never data), and the ring must
be able to hold the hole. The verdict is taken before the stamps, and relative mode's slot advance
is skipped with it, since the advance and the reservation are the same claim. Refusals are counted
in `StreamStats::gaps_refused` and said once per connection with the numbers, naming the wire shape
they describe.
tools/mock_udpstreamer.py gains `--counter-step N`: a counter that is not a packet counter on an
intact link, which is the one shape the mock could not produce and the shape the report came from.
Verified in both directions. A counter stepping 1000 per datagram reads `holes=0 hole_slots=0
backfilled=0` with the traces present (3 traces, 1.4 M samples) against 7.9 M claimed gaps, and the
warning above names the cause. Every other packet withheld -- a real loss -- still reads
`holes=3579`, so genuine gaps are still reserved: a fix that stopped believing real losses would
have traded one wrong picture for another. The user's control read as "the math channel is the
problem" and was confounded -- disabling it is a structural change, which rebuilds the buffer and
clears the accumulated NaN.

measure: the split's own means are back as above/below/between
`top`, `bottom` and `amplitude` became the *flat levels* in

measure: top/bottom/amplitude read the flat levels, not the extremes
A bench scope separates Vtop/Vbase from Vmax/Vmin because a band-limited edge overshoots and rings: the mock's `square` at 30 harmonics reaches ±1.179 where its plateau is ±1. On the rippled square the old readings were a property of the edges rather than of the waveform -- `top` 0.986496, `amplitude` 1.179350 -- and `amplitude` reported the overshoot. `top`, `bottom` and `amplitude` are now the flat levels and their delta. A flat level is a density question -- the plateau holds most of the samples and the ringing a few percent -- so `measure_scan_buckets()` folds a 64-bin histogram of the whole buckets' midpoints while it has the list in hand (one observation per bucket, each bin carrying its buckets' exact sum and finite count), and `measure_flat_levels()` takes, either side of the split, the densest bin holding at least half the densest one's buckets -- the outermost of those, which is what makes a waveform with no plateau read its peak -- and the exact mean of the samples of the buckets within 5 % of the window's peak-to-peak of it. 5 % is deliberately under the ~9 %-of-swing Gibbs overshoot. `amplitude` is `top - bottom` (a scope's Vamplitude), not the half-swing it was. Measured, fast mock, 2 s window, harmonics 0 -> 30: top 1.000000 -> 0.999983, bottom -1.000000 -> -0.999983, amplitude 2.000000 -> 1.999966, while `peak to peak` keeps the extremes (2.000000 -> 2.358701). On the 1 Hz sine top is 0.957988 (it was 0.636620, the half-wave mean; a sine has no plateau, so the densest band is at its peak) with sd 0.0014 over a scrolling window, and `peak to peak` is still exactly 2. No raw pass and no new fetch: the histogram is the same fetched bucket list read a second time, gated on a pane that holds one of the three types. `raw` is unchanged (0.1% clean, 2.1% with the --noise 0.1 interferer, against 0.1%/2.1% before) for 0.44 -> 0.50 ms and 0.52 -> 0.65 ms a pass. A window the pyramid cannot summarize -- an hf-filtered walk, or one shorter than a bucket -- keeps the old readings: the mean of each side of the split, and the window's peak to peak for amplitude. Docs: the flat-level invariant (and the two 2/pi assertions it replaces), the probe readings, the manual's measurements page and the README. |

mock: the square's edges ring, and the one probe that wants a step asks for it
The square was the mock's only ideal step, which is the one shape a real producer does not put on the wire. It is now the truncated Fourier series of the step -- `--square-harmonics N` odd harmonics, default 30 -- so each edge overshoots by the Gibbs constant (about 9% of the 2 V swing, y = +/-1.179) and then rings, and `--square-harmonics 0` is the ideal +/-1 step as before. Odd harmonics only, so the series keeps the ideal wave's edge instants and its polarity: the level-0 trigger, the glitch's inverted pulse and the buffer search land where they did. Re-run in pairs (`--square-harmonics 0` against the default), search, condition legs 0/1, trigrenum, disarm, trig trace, measures and events all read exactly what they read before, with only `t0` moving. The reading that moved is the noise probe's group-delay leg, whose `want` is the analytic `tau*ln2` of a step: a band-limited edge reads `delay=0.002770 ratio=1.255`, the same figure on every run. That recipe now asks for the ideal step, so its documented number stays exact; probe-readings says why. The series is vectorised: as a per-sample Python sum it cost ~15 sin() calls a sample, which at the fast mock's 1.3 MS/s made the producer the bottleneck and halved the rate the app saw (the noise probe's span-dependent counts read 22 against 48). Vectorised it adds ~0.5 ms to a 2000-sample packet, so the fast mock runs at about nine tenths of its declared pace and those counts read within a few percent. |

fix: the guided tour selects the page a stop's target lives on
A stop whose target is on another page of a stack was entered without switching to that page, so the spotlight aimed at a widget that was not on screen. A stop now declares the page it stands on (`TourStop::page`) and the tour selects it as the step is entered -- the window's trigger and signals stops put the sidebar on Signals, the chooser's tabs stop shows the Waveforms page and stepping off it brings Sources back. The stop filter moved into `tour_begin()` and now runs on `gtk_widget_get_mapped()`: GTK 4.24's `is_visible()` ignores `child_visible`, so it kept a stop on another page *and* one in a collapsed pane alike. A wrong page is kept and selected; a collapsed pane, whose stack is unmapped too, is still dropped. |

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.

fix: place the guided tour's card from its allocation, and count GTK warnings
The tour measured its card with a height-for-width request whose for_size came from the natural width minus the margins the tour sets for positioning. A measure reports margins *included*, so that for_size landed a margin short of the minimum the box answers with and GTK warned once per frame: Trying to measure GtkBox 0x... for width of N, but it needs at least M (about 9/s for as long as the tour was up). The card now takes its size from gtk_widget_compute_bounds() once a frame has run -- its allocation rectangle, not gtk_widget_get_width(), which is only the content box -- and falls back to a measure with no for_size at all only on a frame with nothing allocated. GTK is built with structured logging, so its messages reach the log writer and never the handler API; no existing probe can read one. The exit dump now counts them (`gtk warnings:`, must read 0) through a writer function chained to g_log_writer_default(), which leaves stderr unchanged. |

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 manual is a Mallard set opened in Yelp, not a GResource in the binary
The help was 14 Pango-markup `.txt` bodies in a second GResource, drawn into a paged `GtkWindow` built in `help_window.cpp`. That made F1 a viewer of ours with no search index, no cross-references and no translation, and it kept the manual in the *binary* when every other desktop application's is a document on disk. It is now a real Mallard set: help/C/org.udpscope.app/ index.page + 14 topic pages + figures/*.png and `show_help()` hands `help:org.udpscope.app` to whatever the desktop registered for the `help:` scheme -- Yelp on GNOME -- through a `GtkUriLauncher`, reporting a launch failure with a `GtkAlertDialog` rather than a click that silently does nothing. The paged window's builder, the page table and `help_self_check()`'s markup validation are gone with the resource. The document identifier is the desktop file's own basename (its desktop-file id), derived in CMakeLists from `data/org.udpscope.app.desktop.in`, so the same string is the `.desktop` name, the GApplication id and the install directory at once. The set is installed by a new `install()` rule to `<datadir>/help/C/org.udpscope.app/` -- where the freedesktop Help System Specification's `help:` URI resolves `help:<id>` -- so the manual is read from a datadir by another process even though the binary has no install step. `UDPSCOPE_HELP_NAME` and `UDPSCOPE_HELP_DIR` are compiled in from that one place. The 14 pages were migrated fact for fact, but restructured the Mallard way: a `<desc>` per page (what a search result shows), `<steps>` for procedures, `<terms>` for option lists, `<gui>`/`<key>`/`<keyseq>` for interface words and keys, `<note>` for the asides, and a topic graph via `<link type="guide" xref="index#main"/>`. The figures are annotated screenshots produced by `tools/make-help-shots.sh`, which drives the app headlessly against `tools/mock_udpstreamer.py` and draws the boxes with ImageMagick; the side panel's box is measured from the app's own `side=NNNx` dump reading, the header and status bands come from a documented table, and a crop whose standard deviation is 0 fails the script. `cmake --build build --target test-help` checks the set the way `test-ui` checks the `.ui` files: `yelp-check`'s offline subcommands (links, media, orphans, ids) and a `yelp-build html` render. `yelp-check validate` is deliberately absent -- it fetches the Mallard RelaxNG schema over the network and fails offline for that reason, not for a fault in the pages. The `[help]` probe reading changes with the resource it was written for. `parsed == pages` over in-binary markup cannot exist now, so `help_self_check()` scans `UDPSCOPE_HELP_DIR` and the line reads `topics=14 index=1 figures=3`; `topics=0 index=0` is the manual missing from the tree, which is the finding the old count named. Verified: clean build with the documented three warnings (the help bundle's `-Woverlength-strings` is gone, so the baseline moves from four to three); test-ui 14/14; test-help clean (the four subcommands and 15 pages rendered); a temp-prefix install lands 15 `.page` files and 3 figures at `share/help/C/org.udpscope.app/`; the headless run reads `[help] topics=14 index=1 figures=3 dir=...` with 0 Gtk-CRITICAL. Yelp's own window could not be exercised on this box -- it starts under Xvfb, activates its portals and never maps, the same WebKit/portal limitation that stops a grab -- so its rendering and its search index are unverified here; the content pipeline was (`yelp-build` renders the whole set). Docs: the manual's build/install/open story in `build-and-run.md` and README; the warning baseline in `verification.md`/CLAUDE.md; the help bullets in `invariants-gtk-and-chrome.md`; the `[help]` line in `probe-readings.md`. |

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`.

feat: the export writes an MDF 3.30 file, so a window loads in ScryLab
A third format beside `.npy` and `.csv`, written by hand in `src/export.cpp` -- MF4 is HDF5 and would mean a library, MF3 is a handful of fixed blocks. The layout is the asammdf 8.8.27 reader's own field list, byte-diffed against a known-good 3.30 file it wrote; the shape is the one ScryLab's data-source contract asks for: one channel group, record-interleaved, the master as the x axis, and the unit in the channel's conversion block. So in MDF the master is `abs_seconds`, named `time` -- the clock that is the same in every display mode -- and the plotted axis goes out as an ordinary channel, `time_relative`. `ExportTable::Column` gained the CONFIG's unit, which only this writer spells out; the `.npy`/`.csv` bytes are unchanged, and `write_export()` now picks the writer for both the dialog and the probe. |

ui: the trigger's wave is a full period again
The bold pass had turned the trigger into half a period — a signal rising above its level — and that lost the thing the glyph is for: the crossings. A crest and a trough read as a wave; a hump reads as a hill, and a trigger that shows no crossing names the "above the level" half of an event. The full-period sine with the dashed level through it is restored, exactly as it was, and the Signals pill carries the same wave again so the pill and the toolbar button stay one picture. The Measure glyph keeps the bold redesign, which is the part that was better: two cursors (a cap over two 4px dashes) beside a ruler of two bands with three 2x4 marks and no end caps. The Signals pill also keeps its two bold channel rows. Verified: `toolbar icons: trigger=udpscope-trigger-symbolic(ok)`; `page icons: measure=udpscope-tab-measure-symbolic(ok) signals=udpscope-tab-signals-symbolic(ok)`; `switcher: policy=narrow pills=2 labels=0 names=2 icon=32x32 size=308x36`; `[side-tab-probe] … advanced=4`; the Preferences dialog opened in the same run with no "not present"; `make test-ui` 14 files; zero `Gtk-CRITICAL`. The icons' blob is 12352 bytes, still over the C99 limit, so the clean-build warning count stays four. |

ui: bolder tab glyphs, and the trigger shares the Signals pill's picture
The previous pair were detailed miniatures — 1px ticks, 2px dashes, a 13-column wave — and at 32x16 that reads as *texture* rather than as a shape, which is what "not clear" looks like. All three glyphs are redrawn bold: one thick band, two thick dashes, few features. - **Measure** is two cursors beside the ruler they read against. Each cursor is a cap over two bold dashes (4px), where three 2px dashes read as a dotted column; the ruler is two bands with three 2x4 marks between them and **no end caps**, because a closed frame reads as a rectangle and costs a fifth of the ink on two lines that say nothing. This is the layout whose first attempt looked like two icons in a box — the difference is entirely the weight and the open ends. - **Signals** is a signal rising above its level beside two bold channel rows. Half a period instead of a full one: at this size a full period is a zigzag and a hump is unmistakably a wave, and the level's marks survive on both sides of it instead of being swallowed by the crest. - **The trigger's own icon** is now the same picture as the Signals pill, so the pill and the button that turns the trigger on are recognisably about the same thing. Each was rendered and read back as an ink map at 1:1 and at 2x before it was installed, and three candidates were compared for the Measure glyph (markers *on* a scale, cursors *over* a ruler, and this): the first two turned the marks and the shafts into blobs at the crossings. Ink is 18%, 30% and 29%, inside the range the icons above them set, and everything stays inset two pixels. Verified: `toolbar icons: trigger=udpscope-trigger-symbolic(ok)`; `page icons: measure=udpscope-tab-measure-symbolic(ok) signals=udpscope-tab-signals-symbolic(ok)`; `switcher: policy=narrow pills=2 labels=0 names=2 icon=32x32 size=308x36`; `[side-tab-probe] … advanced=4`; the Preferences dialog opened in the same run with no "not present"; `make test-ui` 14 files; zero `Gtk-CRITICAL`.

ui: the Measure pill is two cursors on a scale, not a boxed ruler beside them
The previous Measure glyph was two icons sharing a box: a heavy closed ruler frame on the right and two light caps on the left, with nothing relating them. It is now one instrument — two cursors *standing on* the scale they read against, each marker centred on one of the scale's marks, so the pair reads the way the pane works: bracket a window, read it against the axis. Three things the render said, each fixed: - **The closed frame was most of the ink.** Two lines and two end caps cost about a fifth of the glyph's ink and say nothing a ruler's marks do not, so the scale is now one band with alternating marks — long, short, long — hanging above it. - **The caps were dashes, not grips.** 5x2 at 32px read as a horizontal stroke; they are 5x3, like the caps on the toolbar's cursors icon. - **The ticks were finer than everything else.** At 1px they were thinner than the 2px weight every icon here uses, so they are 2px, and every mark alternates in height the way a ruler's do. The Markers' shafts are dashed and meet the band rather than hovering over it, and the whole glyph is inset two pixels like the others, so nothing is flush with an edge that a button's padding or a crop takes a pixel off. Ink: 27%, inside the range the icons above it set. Verified: `page icons: measure=udpscope-tab-measure-symbolic(ok) signals=udpscope-tab-signals-symbolic(ok)`; `switcher: policy=narrow pills=2 labels=0 names=2 icon=32x32 size=308x36`; `[side-tab-probe] … advanced=4`; the Preferences dialog opened in the same run with no "not present" (the plain ruler it uses is untouched); `make test-ui` 14 files; zero `Gtk-CRITICAL`. The icons' blob is 12624 bytes, still over the C99 limit, so the clean-build warning count stays four. |

ui: the trigger glyph is a sine crossing its level, and every glyph is inset
The trigger's toolbar icon was a rising edge, which names only one of the four shape triggers the panel offers. It is now a sine with a dashed level through it — the trigger's actual job, find the signal where it crosses this — and the Signals tab's pill carries the *same* picture beside the channel list, so the pill and the button that turns the trigger on read as the same idea. Both are one period of one-pixel stairs, the way the plot rasterises its own traces. Everything is inset two pixels now. The previous drafts ran their level and their bars flush to the cell edge, which is what makes art look shaved wherever a button's padding or a crop takes a pixel: nothing in either tab glyph, or in the trigger's, touches an edge. Each shape was drawn and then read back as an ink map rather than trusted — the first sine came out as a thin antialiased diagonal (a polygon through whole-pixel vertices has diagonal *edges*), which is why the band is now per-column stairs; the level-through-the-centre arrangement was chosen over level-above-the- centre after rendering both, since at these sizes a level nearer the crest merges with it into a blob. The four glyphs measure 18%, 22%, 25% and 25% ink, inside the range the icons above them set. Verified: `toolbar icons: trigger=udpscope-trigger-symbolic(ok)` and `page icons: measure=udpscope-tab-measure-symbolic(ok) signals=udpscope-tab-signals-symbolic(ok)`; `switcher: policy=narrow pills=2 labels=0 names=2 icon=32x32 size=308x36`; `[side-tab-probe] … advanced=4`; `make test-ui` 14 files; zero `Gtk-CRITICAL` and no missing icon. The icons' GResource blob is 12408 bytes — the SVG sources are embedded, comments included — still over the C99 limit, so the clean-build warning count stays four. |

ui: the tab glyphs are 32x16 pairs, drawn twice as wide
Each tab's icon is now two motifs side by side instead of one in a 16px square: the Measure pill is the two cursors beside the ruler, the Signals pill the trigger beside three channel rows. A 16px cell carries one motif — squeezing a pair into it is what turned both into a smear — and the pill has the width for a pair in a 300px column with two pills in it. Two measurements decided the size, both of which I had wrong from the outside: - **GDK paints an icon into a square box whatever the document's aspect.** `gtk_icon_theme_lookup_icon()` at 32 reports a `32x32` paintable for a 32x16 document, and librsvg fits it: rendered with aspect kept, the artwork comes out `32x16` inside a 32 request. So the pair is letterboxed, not stretched, and `pixel_size` 32 draws it at exactly the size it is written — 1:1, so the 2px bars stay crisp. A fractional scale (24 or 48) is what would blur them, which is why nothing here is drawn at one. - **The bar does not get taller for it.** `switcher: … icon=32x32 size=308x36`: 36px is what the switcher measured with 16px icons too, because the pill's fixed height takes a 32px box without growing. Both glyphs were drawn and then read back as ink maps rather than trusted: the first drafts came out at 39% and 44% ink (a blot beside the house 25–36%), and the tab bar is the last place a shape can be checked, since no screenshot works under this X setup. The finished two measure 23% and 33%. Verified: `switcher: policy=narrow pills=2 labels=0 names=2 icon=32x32 size=308x36`; `page icons: measure=udpscope-tab-measure-symbolic(ok) signals=udpscope-tab-signals-symbolic(ok)`; `[side-tab-probe] … advanced=4`; the Preferences dialog opened in the same run with no "not present"; `make test-ui` 14 files; zero `Gtk-CRITICAL`.

ui: each tab's glyph is a pair, not one icon
The Measure tab is now `udpscope-tab-measure-symbolic` — the two cursors standing across a ruler — and the Signals tab is `udpscope-tab-signals-symbolic` — the trigger's rising edge over the channel list it acts on. Each is a 16px composite rather than one of the icons the toolbar carries: a glyph the toolbar already uses for one thing means two things the moment a tab shows it too, which is why the ruler alone and the trigger alone were both wrong here. The plain ruler stays exactly where it was. `udpscope-measure-symbolic` is the Preferences window's Plot page icon and is untouched; the tab's pair is a new file beside it, so nothing that already meant "the measurement ruler" changed meaning. Seven action icons bundled, nine with the two app icons. Both composites are at the limit of what 16px holds — four features each — so each was drawn and then *measured*: rasterized and read back as an ink map, since the shapes have to be checked as pixels and the house range is 25-36% ink (trigger 25, cursors 27, ruler 36). The Signals list is two rows and not three, so the edge and the list get half the cell each; its bars are all one length, because unequal ones read as a bar chart and a chart is not a list. The Measure ruler's ends are open on purpose: a closed frame puts four more pixels of ink at the left and right edges, which is what turns a ruler into a rectangle at this size. First drafts came out at 39% and 44% ink and were rebalanced to 32% and 36%. Verified: `page icons: measure=udpscope-tab-measure-symbolic(ok) signals=udpscope-tab-signals-symbolic(ok)`; `switcher: policy=narrow pills=2 labels=0 names=2`; `[side-tab-probe] … advanced=4` (switching by page name still works); the Preferences dialog opened in the same run with no "not present"; `make test-ui` 14 files; zero `Gtk-CRITICAL`.

ui: the tabs are icons, and the pills keep their names
Each sidebar page gets its own glyph and no visible text. The Measure tab reuses the ruler
(`udpscope-measure-symbolic`, the icon its deleted toolbar toggle used and the Plot preferences page
still carries); the Signals tab gets a new `udpscope-signals-symbolic` — three rows of a colour chip
and a name, which is what that tab mostly is — rather than a second copy of the trigger glyph, since
one shape meaning two things in one window is worse than a new one. Its bars are all one length: a
set of unequal ones reads as a bar chart, and a chart is not a list.
`AdwViewSwitcherPolicy.narrow` alone does **not** give an icon-only bar. Measured on libadwaita 1.10
by walking the switcher's tree: with `narrow` and a title, each pill holds a `GtkImage` *and* a
`GtkLabel` — 48px of "Measure" inside a 54px pill. So the pages' `title` is **empty** (their `name` is
what identifies them to `select_side_tab()` and to the session file, and both are unchanged) and the
words are re-attached in code: `name_side_tabs()` runs on the first tick — the pills are
`AdwViewSwitcher`'s own and exist only once it is mapped — and gives each pill a **tooltip and an
accessible name** from the page's name, then hides the empty label that would otherwise leave the
icon off-centre. An icon-only pill is still a named control for a screen reader, and the page icon
that does not resolve leaves a *blank* pill, which is why it is read like the toolbar's icons are.
Two readings, because the claim is two claims:
switcher: policy=narrow pills=2 labels=0 names=2
page icons: measure=udpscope-measure-symbolic(ok) signals=udpscope-signals-symbolic(ok)
`labels` counts *mapped labels with text* — a plain mapped count reads 2 either way, because the
narrow pill keeps an empty label in its layout — and `pills=2` is the guard that makes it mean
something: with nothing mapped the rest of the line is void rather than a pass.
Docs: the icon census (six action icons, eight bundled, and what each of the two new users is), the
switcher bullet in `invariants-gtk-and-chrome.md` with the measurement above, the two new dump lines
in `probe-readings.md`, the re-measured GResource figures in `verification.md` (icons 8613 -> 9842
bytes, help 514660 after this session's help rewrite; the count stays four), and the README recording
that the design spec had the switcher showing titles and neither page an icon.
Verified: `make test-ui` 14 files; `[side-tab-probe] … advanced=4` (tab switching by name still
works with empty titles); `signals panel: … divider=1`; `[math-probe] 3 math channels`; zero
`Gtk-CRITICAL` and no missing icon.

test: a probe reads the hidden tab's accumulator, and the docs follow the tabs
`UDPSCOPE_PROBE_SIDE_TAB_MS` is the one reading for the design's §5 rule -- the statistics accumulator keeps running on the hidden page -- which nothing tested before. It switches to Measure, forces one pass so there is a baseline, switches away to Signals and reads again two seconds later: `advanced=4` is the assertion, and `advanced=0` is the defect where the accumulation is gated on the visible tab, which would leave a gap in min/max/avg for exactly as long as the trigger was on screen. Two things the probe has to do for itself, and getting either wrong makes `advanced=0` a lie about the tab: - it **enables its own signal**, because a signal starts disabled (enabling is what starts acquisition) and a probe that waited for one to be on would be reading another probe's side effects -- and `UDPSCOPE_ENABLE_ALL_MS` is not part of this run; - it **assigns that channel to a plot**, because a channel with no trace leaves the live window *still*, and a still window is precisely the state `update_measures()` is supposed to skip. Measured the hard way: without the assignment the probe read `advanced=0 min_n=0` with the view pinned and only four passes in twelve seconds, none of them the tab's doing. Docs: `probe-readings.md` gains the probe's entry and the signals panel's new shape (`rows == signals + 1 + math`, `divider=0` a list that lost its `+`), loses the whole `math panel:` entry, and follows `pane_sensitive=`, the gone `revealed=` field, the six toolbar controls and the tab-reading `m`/`g` key pairs. `verification.md` gains the probe's bullet and the re-measured warning figures. The invariants record the sidebar as a switcher above a stack with a scroller per page, the hidden-page trap that replaces the unrevealed-revealer one for it, that a feature's on/off is sensitivity rather than visibility, that a math channel is a row of the signal list, and that a cursors-off readout blanks to `--` with the panel left on screen. `shortcuts.ui` and the help page's window and sidebar bullets stop describing five revealers. The README records the deviation from `SPECS.md` that names the panes as separate collapsible sections. Verified: `[side-tab-probe] page=signals rows=4 accums=4 advanced=4 min_n=16`; `signals panel: labels=2 list=1 rows=9 signals=4 math=4 divider=1`; `panels: … (page_current=1) (sensitive=0) switcher=1`; `toolbar icons:` six controls with every name `(ok)`, with the Preferences dialog opened in the same run; zero `Gtk-CRITICAL` and no missing icon. |

fix: a file view states its pin once, so the axis holds still
`set_data_pin()` takes a range and `pin_event_window()` a pre/post split; the file view handed the split to both. On a recording whose stamps start before zero that stored a pin that no longer held the data, so every second frame found the pin wrong and stated it in full again -- rewriting the group's x range and discarding the user's gesture with it. The view alternated between the file's span and the corrupted one at the frame rate: a flicker in which no pan, zoom or click survived. `[drop-probe]` now reports the view and the count of pin statements, which must stay at two for a whole run.

fix: a loaded recording is filtered into its buffer, not truncated
The loader pushed one slot per file row while the plan decimated by eight, so a 10 M-row file overran the ring and only its last 4.19 s survived -- a 20 s recording that read as a 4 s one. Each group of `time_stride` rows is now averaged into one slot at the group's mean stamp, as the packet path already does, and the load line reports rows and decimation so a filtered file cannot be mistaken for a truncated one.

docs: the noise probe arms at 4 s, not 3, and why
`UDPSCOPE_PROBE_NOISE_MS=3000` collides with `enable_all_probe`'s own last act, which fires at
`ENABLE_ALL_MS + 2000` = 3 s: that lambda walks `signal_list` for the front channel's acquire
tick and clicks it, and a probe that installs a math graph at the same instant rebuilds the
signal panel under it. The off-step then emits `active` on a freed `GtkCheckButton` --
`GLib-GObject-CRITICAL: instance with invalid (NULL) class pointer`, stack in
`enable_all_probe()::{lambda}` -- which the baseline ("no Gtk-CRITICAL at all") counts as a
finding. Confirmed by bisection: armed at 3 s it is reproducible, at 4 s it is gone, and a plain
exit-dump run shows none.
That fragility is the probe's, not the feature's, and it is now documented beside the recipe: every
documented probe time is offset from `ENABLE_ALL_MS + 2000`, not merely from the other probes.
The reading times move with it (legs ~11.5 s, de-noise ~16.5 s, both inside the same 18 s exit),
and the corrected run reproduces every documented figure bit for bit.
Readings at 4 s: `setup channels=1`, `trigger band: bare=49/2 band=7/2 ratio=7.00`,
`trigger hf: hf=7/2 band+hf=7/2 band=7`, `pw`/`period band`/`period hf` exactly 0.200000,
`measure windows=2`, `denoise raw=2.987696/1 denoised=2.000000/1 ratio=0.669 channels=1`, no
`Gtk-CRITICAL`.

test: the noise probe reads the de-noise node, and the math probe builds one
The probe gains a staged chain rather than one phase, and the schedule moves with it: `UDPSCOPE_PROBE_NOISE_MS` now times the *setup* stage, which installs the de-noise graph through `apply_math_channels()` -- a structural rebuild that replaces the buffer and drops its history -- five seconds before anything scans it. The legs and the five measurements then run at about 10.5 s, and the reading that says the median rejected every impulse at 15.5 s, so the documented run needs a 20 s mock and an 18 s exit. The de-noise channel is installed **disabled** and enabled only at 13 s, for its own reading. An acquired channel is a share of the ring, so a fifth one shortens every channel's retained span -- and the six `BufferSearch` leg counts and `pkpk bare` are all peaks and counts *of that window*. Installing it enabled (as the plan had it) moved `bare` from 49 to 21, `ratio` from 7.00 to 3.00 and `pkpk bare` from 2.988 to 2.488, i.e. it would have rewritten the older feature's documented proof to record a regression that is not one. With it enabled only at the end, every reading from Tasks 4 and 8 is bit-for-bit what the doc records, and the new line reads `denoise raw=2.987696/1 denoised=2.000000/1 ratio=0.669 channels=1` -- `denoised` exactly the clean sine's 2.0, which is the claim the node makes. Two other findings, both folded in: a derived channel whose source is switched off through the panel's checkbox follows it off and does *not* come back when the source returns (the enable-all probe's last act switches `sine` off at ~3 s), and the probes reload leftover math channels from `$XDG_CONFIG_HOME/udpscope`, which is why a `setup channels=` count above 1 means an earlier run's session, not a defect. `math_probe` gains a third channel with a `DeNoise` node so the editor's median row is built and synced on a baseline run: `3 math channels on 'sine' and 'noise'`, every other line as before, `math cost: 103.3 ns/slot` (one reading of the same path). verification.md: the recipe, and why the two stages may not be collapsed -- a probe that rebuilt the buffer under its own legs reads `bare=0` and looks like a broken comparator. Also that the noise and math probes may not share a run: both write `app.math`. |

test: the noise probe reads a measurement's band and HF reject
Five measurements on the same spiked `sine`, asking for corners 0, 50, 0, 0, 50 on one
channel: two windows under the (channel, fc) key, which is what exercises it.
measure pkpk bare noise=10.0 hf=0.0 value=2.987692 the stimulus, impulses included
measure pkpk hf noise=10.0 hf=50.0 value=1.990075 the waveform: pass one is filtered
measure period noband noise=0.0 hf=0.0 value=0.021290 supposed to be WRONG -- the control
measure period band noise=25.0 hf=0.0 value=0.200000 the band alone
measure period hf noise=0.0 hf=50.0 value=0.200000 the reject alone
measure windows=2 the corner is part of the key
`pkpk hf` is the reading that says the filter reached *pass one* and not only pass two; a
value near 3 means it did not. `period noband` is deliberately the defect the band exists to
fix, and a future reader who "fixes" it has removed the check.
The band leg asks for **25 %** rather than the 10 % default, and that is arithmetic rather
than a workaround: the band is a share of the *window's* peak-to-peak, which with the
impulses in it is about 3, so 10 % is a half-band of 0.3 -- less than the 0.5 an impulse
moves the signal by. `MeasureOptions::noise_pct`'s own rationale says 10 % holds to a 0.3
interferer, and this mock's is 0.5, so the default could not clear it. The default band is
what the `period noband` and `period hf` legs are about.
verification.md now says the noise and measurement probes must not share a run: both push
onto `app.measures` and the later one would read the earlier one's rows.

test: the noise probe reads the trigger's band and HF reject
Six legs over one retained buffer, each a full rising-edge search through `BufferSearch` at
level 0, run back to back without yielding so every leg sees the same samples: the bare
comparator on a spiked sine, a 0.8 band, a 50 Hz reject, both, and the reject's group delay
on `square` -- which carries no impulses, so a one-pole's crossing of zero after a step is
exactly `tau*ln2` and the delay is an exact prediction rather than a coincidence.
trigger band: bare=49/2 band=7/2 ratio=7.00
trigger hf: hf=7/2 band+hf=7/2 band=7
trigger delay: clean=4 filtered=4 delay=0.002206 want=0.002206 ratio=1.000
`ratio >= 5`, both HF legs within 2 of the band, `ratio` between 0.7 and 1.4, `state=2` on
every leg, no Gtk-CRITICAL. `bare` and `band` are proportional to the retained buffer, so
neither is a fixed number; the ratios and the agreement between legs are the assertions.
The probe enables the signals it measures itself rather than relying on another probe's side
effects -- `enable_all_probe` ends by switching one off again, which is how `sine` was missing
from the first run of this one -- and arms in two phases because that enable is a structural
change that replaces the store, so the ring has to fill before there is anything to search.
Its "no stream" line now names the channels that *are* there: an index alone says a probe
found nothing, not what it saw.

perf: a frozen frame is not re-rendered sixty times a second
The tick queued a GL render unconditionally. In `Held` and `Paused` the rows are bound to an immutable snapshot on a pinned axis, so a frame in which none of the picture's own terms moved is the same frame again. The gate keys on a coarse signature of what a frozen view can be re-framed by, opens for `kSettleRenders` frames on a change because the figure lays out per render, and has a floor that renders anyway every few ticks. The layout editor is excluded: its buttons are placed from the last frame's rects, so a skipped frame there is a stale widget rather than a stale picture. `skips=` in the probe dump is the reading.

ui: the source chooser's window is a .ui file, and its pages an AdwViewStack
The last hand-built UI outside ui.cpp. The window, its header bar, its two pages and the four buttons that are about the chooser rather than about a source now live in src/ui/source-chooser.ui; the rows stay in code because a source row and a waveform row are data, rebuilt whenever the known hosts or the recent files change. The pages were a GtkNotebook and are an AdwViewStack under an AdwViewSwitcherBar, which is what current libadwaita asks for and the same information without a tab strip. The three actions moved from a button row at the foot into the header bar, the shape source-form.ui already uses -- and deliberately without receives-default, since Enter must keep activating the selected row. Nothing carries a value: the tooltips and labels moved as they were, the handlers are the same functions, and the switch is by page *name* rather than by index. The probe reads the frame back -- `[sources] chooser ui: page='sources' title='Sources' icon=yes page='waveforms' … switcher_wired=1 buttons=[prefs=1 new_host=1 open=1 cancel=1]` -- so a .ui that lost an id is named instead of opening a window with a hole in it, and `check_ui` type-checks the file against the GIR (7 ok, 0 failed). Two things the checks caught while doing it: the new frame dropped the call that fills the waveforms page (the unused-function warning), and `AdwViewStackPage` is a GObject that *wraps* a child rather than being one, so reading the pages needs adw_view_stack_get_page(). |

udpscope: an oscilloscope view for a UDPStreamer source
GTK4 and libadwaita. It receives one UDP stream through the vendored udpsclient, buffers it in a large ring, and draws it with the vendored plotter: a trigger with a pre/post event window, a pause that freezes the window, cursors, measurements, math channels in a node editor, an event cache, named configurations, preferences, and an export of the visible window to .npy/.csv. Waveform files can be opened and analysed in place. The interface is two threads -- a producer that owns the socket and the GTK main thread that owns every widget and the GL context -- sharing one model under one mutex, with samples crossing through lock-free rings. deps/plotter is a submodule pinned to the commit this tree builds against; deps/udpsclient is vendored in place. docs/claude/ documents the rules that cost a defect to learn, and SPECS.md is the requirement document. |

docs: the five reseq probe cases as this build measures them, plus the overflow counter's reading
Re-measured all four recorded cases and added a fifth for the re-plan path, which needs 100 kS/s: at 10 kS/s the ring already covers 838 s, so no window the control can reach moves time_stride and the window probe re-plans nothing. Also notes that `stale` is 0 by construction while resequencing is on, and that the reservation cap is counted in packets, so its sample cost scales with the batch.

feat: the mock can drop and invert packets, and carries a noisy channel
--drop-every/--drop-burst withhold datagrams the counter and stream clock have already advanced over, and --reorder-every inverts a pair on the wire; both are deterministic for the reason --glitch-at is, since a probe asserts the spacing of what it finds and a random count is not a figure. A `noise` signal gives the dense-trace and intensity-floor paths a input that is not piecewise smooth. verification.md records the measured readings, including the one that is a finding rather than a baseline: a burst past kGlitchPackets (256) is read as a producer clock glitch, each bridge advances the anchor by one packet span against a timeline 300 ahead, and four consecutive failures then throw the stream onto the arrival clock.

fix: a clock glitch is bridged and a channel is known by name, so a capture keeps its t0
Two defects behind one report ("a trigger during a capture overrides the first,
and the hold-off does not apply"); the second is also what made a spike in one
channel look like the acquisition resetting.
The trigger engine keyed its invalidation on the trigger channel's *index*, which
every rebuild of the channel list renumbers -- enabling a signal that sorts before
it is enough. Any rebuild therefore abandoned an open capture and set no hold-off,
so the next edge inside the post window became t0. It keys on the channel's name
now, which changes only when the source genuinely does.
A packet whose stamps jump more than 256 packet spans ahead is now rejected as a
fault and *bridged* at the declared cadence, instead of poisoning the monotonic
mark (which pinned every later packet flat at the glitched value) and condemning
the next good packet. Only four consecutive failures abandon the declared time
signal, and that fallback no longer wipes the rings: the arrival clock is anchored
to continue from the monotonic mark, so the history is still on one timeline --
the wipe is what made one glitching packet look like the stream restarting from 0.
The declared unit is resolved before those checks, since they weigh the stamps
against a cadence in seconds.
Guards: UDPSCOPE_PROBE_TRIGRENUM_MS prints t0_held=1 through the real widgets,
and the mock's --time-glitch-at/--time-glitch-by injects the clock fault.

feat: a signal's chip is clickable, so a trace's colour is the user's to choose
Clicking the coloured chip in the signal list opens a GtkColorDialog and the colour it returns overrides that signal's palette entry. Held by name, like every other identity here, and persisted as a session `[[color]]` table. RowSet::signal_color() becomes the one resolver: install() builds the trace through it and all three chip sites read it, because a chip exists to say which trace a row is about and an override is exactly the state in which two routes to a colour would disagree. A grey chip names no trace and so is not clickable, and the way back is `Default colour` in the signal's menu -- a setting with no undo is a trap. The gesture sits on the existing label rather than in a GtkButton: padding on this row is what made the signal list twice as tall once. It claims its sequence so a click on the chip cannot become the start of a row drag. UDPSCOPE_PROBE_COLOR_MS reads the result out of plot::Plot::trace() and out of the chip's own markup, with an override in no palette slot, so neither leg can pass by asking the resolver what it already said.

fix: a wire is picked by distance and a refusal is spoken, so the editor answers
A review of the whole node editor. The hit test measured the distance to the 24 curve samples rather than to the segments between them, so a wire spanning several rows was unpickable between two samples -- the probe now places its boxes 280 units apart and prints the nearest sample's own 8.4 against a 3.0 tolerance, which the point test would have missed. A refused connection said nothing: the message is now carried in `MathDialog::refusal` and shown once by the single writer of the label, and a self-wire is refused through the real drag-end path instead of only through `math_connect()`. Two defects were found only by the new assertions. `math_dialog_sync()` re-entered itself -- `gtk_drop_down_set_selected()` emits `notify::selected` for a programmatic set too, and the handler answers by syncing again, which consumed the refusal before it could be drawn -- so the body is now guarded one level deep. And a deleted node left `selected_wire` naming an index that afterwards belongs to a different wire, so `Delete` cleared an input on the wrong node. A node is placed in the first free grid cell rather than at the end of the list's own cell, so a node added after a delete no longer lands on top of a survivor; the label ellipsizes with a tooltip rather than wrapping, because a wrapped line makes the dialog's height depend on the text in it. |

docs: the node editor's gestures, its new probe assertions and its invariants
Each invariant records what went wrong rather than only the rule: a port hit that lost its node, a hit test at the identity view that asserts nothing, a `Delete` that must not fall through to the selected node, and a column pitch too narrow for a wire's own tread. The warning baseline drops to four. |
