One op, not two: a running median followed by a one-pole at `fc`. The median kills an impulse
outright -- a peak shorter than half its window cannot move it at all -- and the pole then
takes the broadband hash the median leaves behind. Chaining the existing `LowPass` after a
median would let the user wire them the wrong way round, and a pole *before* a median feeds
the impulse into the filter's state for its whole settling time, which is the thing the node
exists to avoid.
`DeNoise` is **appended** at `math_op_at(12)` (with `Div` given its explicit `case 11`, so the
`default` no longer swallows it): a session stores an op as its index through that accessor,
so inserting it beside the filters in the dropdown would reinterpret every node in every
existing session file. It sits last in the dropdown instead, which is the right side of that
trade.
The median window is `MathNode::med_n`, odd and 3..9, enforced by `median_n()` rather than by
the dialog -- a file holding anything else still loads -- and the ring is *pooled* in
`MathRuntime::median`, sized in `math_prepare()`, because nine doubles as a member would push
`MathNodeRt` across two cache lines for every node, filter or not. The pole reuses `b0`/`z1`,
which `math_prepare()` already carries across a re-prepare, so a decimation change does not
make its trace jump.
Warm-up takes the median of what the window holds rather than NaN: in this application NaN
means *a hole in the data*, and spending that meaning on a start-up transient would make a gap
ambiguous. A non-finite input stays a hole and leaves both the window and the pole alone.
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.
Two rows in the measure dialog, built the way the threshold and side rows are and appended
beside them: the band as a percentage of the window's own peak-to-peak (the unit the engine
takes), the corner in Hz with 0 off. They are seeded when editing, shown only where they do
something -- the band for the crossing types, since it moves the edge decision and nothing
else, the reject for all of them, since it sits before both walks -- and read into
`MeasureOptions` on apply.
They persist as two *named* keys, `noise` and `hf`, on the same `o <<` chain as the keys
beside them and read back through the same keyed reader, so a session written before this
change loads with 10.0 and 0.0: today's behaviour exactly, with no version check.
[configs] now proves the round trip rather than assuming it. The probe sets the first
measurement's band and corner to 7.5 and 250 before saving, so a key that never reached the
file reads back as the defaults:
[configs] round trip read=1 comment='written by the configs probe' ... measures=4 math=0 noise=7.5 hf=250
The rest of that line is unchanged, and the run is free of Gtk-CRITICAL.
The pane shared its two walks per *channel*, but the HF corner is a per-measurement
setting: two measurements on one signal at different corners read two different signals
and cannot share a walk. `App::MeasureWindow` therefore carries `channel` and `fc`, the
container is a vector, and the grouping loop matches on both -- keeping its dedupe of the
level accumulators by `(pct, noise)`, since a type that does not read the band must not
split an accumulator over it.
Each window carries two filters, one per walk: they are separate walks, so separate state.
A filtered window also stops using the LOD pyramid, which one `if` does -- leaving
`buckets` empty makes `bulk_from == bulk_to == n`, so the raw walk covers the window and
`lo_search`/`hi_search` stay 0, which makes the pinning pass a no-op. Nothing downstream
needs to know.
The readout loop looks its window up by index rather than by channel, which is what the
`(channel, fc)` key needs.
The documented measurement baseline is unchanged, and it is the assertion:
[measure-trace] average=0.000000 top=0.636620 peak to peak=2.000000 amplitude=1.000000
[udpscope] measure cost: ... covered=75378013 buckets=1177164 raw=159674 (0.2%)
`top` is 2/pi to the digit -- the one reading a band leaking into the sums would move --
and `raw` at 0.2 % of `covered` says the fast path is still being used on an unfiltered
window.
The measure probe now enables `sine` itself, as the noise probe does: `enable_all_probe`
ends by switching a signal off, and with `sine` gone the probe measured `square`, where
`top` is 1.0 and the baseline above is unreachable.
`MeasureOptions` gains `noise_pct` (the hysteresis band, % of the window's peak-to-peak,
defaulting to the 10 % the file-scope constant held) and `hf_fc` (a one-pole HF reject over
the measured window). The band's measured rationale moves with the number rather than
becoming an orphan comment, and `measure_set_level()` takes the fraction as an argument
because the band is a per-measurement setting while the call is once per level.
`MeasureFilter` is that reject as a walk carries it: one pole, one state word, `a == 1` a
pass-through so an unfiltered walk pays a multiply and no branch, and a non-finite sample
passing through without touching the state. Both raw walks step it -- and stepping it is why
`measure_accumulate()` now loops samples-outer/levels-inner: a levels-outer loop would step
one filter state once per level per sample, and every level after the first would read a
signal filtered k times over. The inner `continue` is a `continue` of the *level* loop, which
is what it has to be: a sample inside one level's band may be outside another's.
`measure_uses_noise()` names the three types the band reaches (the crossing types -- a band
moves the edge decision and nothing else), and both bucket functions say in their comments
that a bucket aggregates unfiltered samples, so a walk with a reject must not use them.
This leaves `ui_measure.cpp`'s five call sites failing to compile, deliberately: they are the
next task, and pretending otherwise would mean a shim that the task then deletes.
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.
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
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.

`plan_partition()` only ever chooses powers of two for `time_stride`, and the
comment there already claimed the test was cheap -- but the stride is a runtime
value, so `tick % period` compiled to a real division that the hot loop paid
once per channel per wire sample. The per-channel masks are built where the
partition is already reacted to, and the shared clock's group end is computed
once per sample instead of three times.

The design spec is approved; this turns it into the task-by-task plan an
implementer with no context can follow, with the four places the plan
deliberately departs from the spec collected and argued at the end.

EM interference is impulsive, so each place gets an amplitude qualifier and a
frequency one, both optional and both defaulting to today's behaviour: the
documented reading set has to come out unchanged. Records why the trigger's
zero-band path stays bit-for-bit, why a measurement filter gives up the bucket
fast paths, and why the new op is appended rather than placed beside the filters.

A derived channel cannot be computed from a signal nobody acquires: `Source` resolves to a
*channel*, and a disabled signal has none -- so a channel that reads one silently computed
nothing, which is what "all math signals depending on it do not compute anymore" looked like
from outside.
Rather than leave it enabled and blank, the channels that read the signal follow it off:
`disable_dependent_math_channels()` walks the graphs to a **fixpoint**, because one math
channel may name another, and the switch goes through the same path the pane's own toggle
uses -- `MathChannel::enabled` then `apply_math_channels()`, the single writer -- so the
pane's switches follow. Their traces leave the plots with the signal's, and the notice says
both halves.
The channels that do *not* read it are untouched, which is the assertion's other half:
[enable-all-probe] switched 'sine' off: traces_left=0 (want 0)
math_off=[math x2,math3] math_on=[math lp]
notice=''sine' is off: 1 trace left the plots; math off: math x2 and 1 more'
`math x2` and `math3` both source `sine`; `math lp` sources `noise` and stays on. The probe's
switch step now runs late enough that a math probe armed behind it has installed its graphs,
which is why the earlier reading was empty -- `app.math` had nothing in it yet, not
"no dependants".
Re-enabling the signal does not switch them back on, for the same reason it does not restore
the traces: that is the user's decision, and the rule is written down in
invariants-math-channels.md.
`set_math_channels()` rebuilt the store for any change, and a rebuild replaces the buffer:
every channel in the window started again, which is the "modifying one expression invalidates
all the others" report.
The plan is a *partition over the channels*, so it only moves when the set moves. When the
set is unchanged -- same channels, names and enables -- nothing is rebuilt now: the store is
untouched, every other channel keeps its samples and its runtimes, and the surgical path
prepares and recomputes only the affected graphs. The affected set is the edited channels plus
whatever *names* them, because one channel's output is another's input, and the recompute
computes the whole list in order (the inputs have to be there) while writing only those in
the mask -- which is why the step-loop is now `math_apply_locked(sample, write_mask, timed)`.
Adding, removing or renaming a channel still moves the plan, and still rebuilds.
[math-probe] graph edit: stored_slots 800 -> 900 (want the second at least the first, and non-zero)
The count grows because the stream keeps filling while the edit runs; the point is that it
never falls to 0, and that every channel afterwards still reads `N samples vs M time slots`
with N == M.
The switch in the signal list means "do not acquire this", and until now a trace of it
stayed on its plot drawing nothing: a slot that holds one of the four a plot has, reads
`--`, and blocks the drop that would fill it with something live.
`on_signal_switch()` now clears every slot that holds that signal, by the **signal name**
the slot remembers -- never the channel index, which is what the enable change renumbers --
and says what it did: `'sine' is off: 1 trace left the plots`. The follow-ups (a relayout,
the panels' chips, the layout save) happen once rather than per slot.
Re-enabling deliberately does not put the traces back: the arrangement is the user's, and
guessing where they were is worse than leaving them off. Say the word if you want that
direction too.
[enable-all-probe] reads it end to end -- it enables every signal, assigns the channels
across the rows, then switches one off *through its own acquire tick*:
[enable-all-probe] switched 'sine' off: traces_left=0 (want 0) notice=''sine' is off: 1 trace left the plots'
which is also why the notice shares the status line's warning styling from the previous
commit: the trace leaving the plots is something the user should see happen.
The refusal was never silent -- `on_drop_channel()` has always set a notice -- but the
status bar renders `notice + " | " + glance` in one label, so "plot 1 already holds
four signals" arrived looking like part of the routine text a reader skims, which is the
"no clear user feedback" report. The probe's own reading showed it plainly: the label held
`plotting 'sine' on plot 1 | live · 4.44 kS/s · 2 s window`.
Three changes:
- While a notice is fresh the status label carries the stock `.warning` class, so a message
looks like a message and the class goes when the notice does. Every notice benefits, not
just this one.
- The refusal says what to *do*: "plot 1 holds four signals already: drop it on another
plot, or add a row with the layout editor (L)".
- The drop's inline notice now goes through `set_notice()`, the one setter, instead of
writing `app.notice` and its deadline by hand.
[drop-probe] reads the whole path, with the row filled first so the drop under test is the
refusal:
full row refused the drop: 0 (want 0)
refused feedback: notice='plot 1 holds four signals already: ...' warning=1
the status line, composed: warning=1 status='plot 1 holds four signals already: ... | live · 9.97 kS/s · 2 s window'
The label is read in the third line and not the second on purpose: the status line composes
the notice into itself on its own cadence, so a beat after the refusal it may still hold the
previous text -- which the first attempt at this reading mistook for the fix not working.
The row limit is not silent in the same way: the layout editor's `+` is insensitive at
`kMaxRows`, which is a control that says "no" by being unusable rather than a message.
The window control is a GtkMenuButton whose popover autohides -- which works for as long as
GTK holds the popover's grab, and the grab is what can go missing: a window manager moving
it, the nested popover the unit dropdown opens taking it, and every headless run, where
there is no manager to hand one out at all. After that a click anywhere else in the window
leaves the bubble up, which is the "sometimes it is awkward to close" report.
`on_window_popover_press()` states the rule outright instead of relying on the grab: any
press that reaches the window's own surface closes it. That needs no hit test beyond the
button -- a popover is its own surface, so a click *inside* it never arrives here -- and the
button is left alone, because its own click is the toggle that closes it. The press gesture
is on the window in the capture phase, so a widget under the press (the plot's own gestures
among them) cannot hide it.
[windowpop] reads both halves, with autohide turned off for the probe -- the state a user
meets when the grab goes missing:
[windowpop] opened=1 visible=1 click_gestures=2
[windowpop] after a press elsewhere: active=0 (want 0)
[windowpop] after a press on the button: active=1 (want 1)
`click_gestures` is read as well as the handler, so "the rule works" and "the rule is
connected" are two facts rather than one.
Three tightenings, all measured with the reloads now reported on stderr.
`set_math_channels()` treats an identical list as no change at all. It rebuilt
unconditionally, and a rebuild replaces the buffer and drops its history -- which a file
view then has to re-read from disk. The comparison is the graphs', and it leaves the nodes'
`x`/`y` out deliberately: those are the canvas's own, no op reads them, and a graph that
merely *moved* should not cost the buffer.
`reload_file_view()` fires only when the store is actually empty. A change that really
happened leaves it so in a file view (the rebuild replaces it, and there is no producer to
refill it); one that found nothing to do leaves it full, and reading a 200 MB file again for
that is the waste. `ScopeModel::stored_slots()` is the one-line accessor it needed.
Every reload now says so, because a second read of a file is worth accounting for:
[udpscope] reloaded <path> after a structural change: 402 samples back
Measured, `--open` a file:
session with no graphs 0 reloads
the math probe (3 real changes) 3 reloads, and all the readings stay equal
(`math x2 402 samples vs 402 time slots`)
I had offered this as "one extra read at `--open` startup", and that was wrong: with no
session there is no `apply_math_channels()` call at all, so there was never an extra read
to remove. What the tightenings buy is that a no-op application is now free, and that a
reload cannot happen unless the buffer was really lost. Each *genuine* change still costs
one re-read -- a rebuild drops the history by design, and preserving it across a rebuild is
a model change rather than this one.
Two defects, both reached by adding a math channel to an open waveform or a replayed
event, and both measured before and after.
**A file view has no producer, so a structural change left it empty.** `set_math_channels()`
rebuilds the channels *and* the buffer, and a rebuild drops the history: right for a stream,
whose producer refills it from the next packet, and wrong for a file, which has nothing to
refill it with. The `--open` dump read `0 samples vs 0 time slots` for *every* channel,
the file's own `sine`/`square`/`ramp`/`noise` included, though the load had reported 402 --
that is what "adding a math node breaks the plotter" was. `reload_file_view()` re-reads the
file after such a change, which is also what computes the derived channels over it: the
load's own pushes run the math once the set is in place, so `--open` with a session that
defines graphs works for the first time.
**The file path pushed into the derived rings, and so did the engine.** `push_loaded_slot()`
did not honour the rule `ChannelInfo::math` states for the packet path ("the ingest must skip
it"), so each loaded slot put a value in a derived ring and `push_math_sample()` then put the
computed one: two samples per slot, a trace at double rate -- the derived channels read
`804 samples vs 402 time slots`. Skipping them there is the whole fix.
Readings now, all equal, which is the assertion this file's own invariant makes:
--open the file: math x2 402 samples vs 402 time slots, y=[-1.9021, 0.0063] (2x the sine)
math lp 402 vs 402, mean=-0.4900 (a real filter output, not zero)
live: math x2 25100 vs 25100
replayed event: math x2 4000 vs 4000
I first tried filtering the file's *derived columns* out by name, since an export writes
every plotted channel. It removed the double count and zeroed `math lp`, because the column
it dropped was the source a session graph reads -- so it is reverted: those columns are
legitimate data, and the fix belongs in the push, not the loader.
Moving the editor's frame into math-editor.ui left `math_body` and `math_actions` as
<child> elements of the *window* rather than of `math_outer`, because those edits were
anchored on the file's tail and closed the outer box two elements early. A GtkWindow
takes exactly one default <child>, so nothing failed loudly: the body -- with the canvas
and the parameter form inside it -- was left parentless, visible but never mapped, 0x0,
drawing nothing. Two symptoms, one cause: the canvas is blank, and the window is sized
around the head row and the buttons alone.
Measured against the pre-move revision in a worktree, same probe, same environment:
before this fix `canvas=0x0 mapped=0 window=756x940`; after it `canvas=420x836 mapped=1
window=938x940`, which is the old revision's own reading exactly.
It survived because that slice's probe read the editor's *values* (nodes, gain, output,
name, unit) and nothing about its structure. Every other panel moved that day has a
structural reading -- `controls_inside=13/13`, `nested=1`, `labels=2 list=1` -- and none
of them was affected. `[math-probe] editor frame:` is that reading now: the canvas's
allocation, its mapped state, and whether the canvas and the name entry are inside the
dialog at all, delayed 500 ms because an allocation only exists after a layout. In the
broken build it read `0x0 mapped=0 in_dialog=0`.
check_ui passes both files: the XML was valid and every property type-checked.
Two directions of the same link: the plotter's README now names and links this project,
and this README's link to the plotter was a relative path, which a forge renders as a 404.
It points at the repository now.
The submodule's pointer moves with its .gitignore fix, which is what made this repository
read as having untracked content in `deps/plotter` on every status.
The submodule's README now names its consumer and links it
(<https://git.ferrarinas.it/martino/udpscope>), which is the other direction of the link
README.md already carried. The pointer moves from be1f31a to that commit.
The submodule is seven commits ahead of its own origin and the parent is ahead of this
one, so both have to be pushed before a clone can fetch the pointer.
todo.md's item 10 is closed with what moved, what stayed in code and why, the reading each
slice added, and the three GTK facts in invariants-gtk-and-chrome.md. The plan's table is
marked complete, with the note that the header bar went last and in one change -- pack_start
appends after whatever a file packed, so staging it by group would have reordered the bar in
an intermediate commit.
Two facts added to the invariants: a code-added header-bar child lands after the file's, so
going first means the file declares a slot (which is what header-bar.ui does for the
time-window control); and <child type="end"> is added leftwards-from-the-right, so a header
bar's end group reads the reverse of the file.
src/ui/header-bar.ui holds the bar: the time-window control's slot, the trigger, pause and
events group with the separator that marks where the view's controls end, and the five at
the far end. What stays in code is everything that acts on the model -- the overflow
menu's rows, the window control itself, and every handler.
The order is the file's, which is the part the code used to explain in three comments: a
<child type="end"> is added leftwards-from-the-right in document order, so the screen reads
the reverse of it -- cursors, measurements, math, sidebar, menu.
The first start child is a *slot* and not the control, and that is the one thing this move
could not do naively: gtk_header_bar_pack_start() appends after whatever a file has already
packed, so the control -- which is code, its menu's rows coming from the buffer's limits --
would have landed to the right of the whole group instead of at its head.
The probe is the check, and every header reading is byte-identical to before the move: 12
lines of `header:` (window_button_w=130 bar_w=756), `window control:`, `panels:`, both
width-probe frames and all seven layout-probe lines. Only `badge frames:` differs, and it
is a frame counter. check_ui: 14 ok, 0 failed.
The row asked for these buttons in a .ui file and that is not possible: there is one per
row and one more than that per boundary, and a GtkBuilder instantiates a file's objects
once, so the file can hold neither the count nor a prototype for the code to copy. The
plan's note ("only the buttons are template") is wrong for the same reason, and the plan
document now says so.
What was real in the row was the duplication: the look was written out three times -- the
icon, the two CSS classes that make a small round on-screen-display control, the size,
the overlay append and the bookkeeping -- and is now one function,
`layout_overlay_button()`. Each loop keeps only what makes it different: its alignment,
its sensitivity, the data it carries and, for the resize handle, its drag gesture.
The layout probe is the check and its readings are byte-identical before and after, all
seven lines: `buttons=5 done=1 done_box=[680,4,72x42] close=[4] add=[0,832] resize=[(1:-)]`
and the row geometry through add-above, remove, add-at-end and Editor off.
src/ui/events-pane.ui holds the pane: the GtkRevealer that slides it in, the header with
the way back to the live stream, the Compare and Accumulate actions, and the list inside
its scroller. The rows stay in code -- one per latched event, rebuilt whenever the cache
changes -- and their sensitivity stays with update_group_buttons(), which is why the file
only starts the two actions insensitive.
Two statements moved into the file along with the widgets, because they are about what the
pane is for rather than about a default: multiple selection, and activation on *double*
click. With single-click activation the plain click that builds a selection would replay
the event instead.
Read back as `events pane: compare=1 accumulate=1 list=1 revealer=1 nested=1`, where
`nested` is the list being inside the revealer -- the one thing a lost id cannot show. The
[events] probe is the other half and drives the pane end to end: recording, trigger, the
history button, a row click and the replay, then Compare and Accumulate, so the file's
buttons are read by being clicked. check_ui: 13 ok, 0 failed.
The row is the file's -- the box and its two buttons, the second carrying the
suggested-action class -- and what is code is what they do and what the second one says:
"Save" edits an existing channel and "Add" makes a new one, which the file cannot know.
With it the editor's frame is whole: the window, the identity row, the body with the
canvas in it, and the buttons that end it. The parameter form and the palette stay in
code, and for the reason the canvas's *drawing* does -- the form follows which node is
selected and the palette is the operation table itself.
The probe clicks the apply button rather than calling its handler, so
`dialog build: ... name='math3' unit=''; saved nodes=2 output=1` is that button having
worked from the file, and `after close: dialog=cleared` / `reopened: dialog=ok, nodes=2`
are the lifetime around it. check_ui: 12 ok, 0 failed.
The second half of this plan row, and the half of that dialog which is template.
src/ui/math-editor.ui holds the window (its size and modality), the box around it,
the identity row -- the name and the unit -- and the body with the canvas in it.
What stays in code is the drawing: the canvas is a GtkDrawingArea the file *declares*
and the code draws, with the gestures that make it a graph editor, and the parameter
form follows which node is selected. The palette and the buttons go next.
The builder is held on `App` and cleared on the *next* opening rather than with the
window: the window belongs to the builder's object list, so freeing the builder under a
live window frees the window with it. That is the source form's pattern, and the probe's
close-then-reopen path is what exercises it -- `reopened: dialog=ok, nodes=2`.
The identity row is read back too, since a `.ui` can hold the widget but not the value:
`dialog build: ... name='math3' unit='' ...`, the entries having been filled from the
channel being edited. check_ui is at 12 ok, 0 failed.
The first half of this plan row. src/ui/math-panel.ui holds the panel: the box and its
margins, the heading row with the title and the add button, and the list the channel rows
go in. The rows stay in code -- each is a channel with its name, unit, expression, colour
and its own edit and remove buttons -- so the file holds the frame, as in the measurements
and signals panels beside it.
Read back by a dump line that also reads the file's own text:
`math panel: head=2 buttons=1 list=1 title='Math channels'`, where buttons=0 is a lost
`+` and title='-' a lost label. `[math-probe]` still drives the add and opens the editor,
so the rows landing in the file's list is read as well as the frame.
The other half is the node editor's chrome, which is where least of that file is template:
the canvas is a GtkDrawingArea that is drawn rather than declared, and the gestures, the
parameter fields and the palette are code. That is its own change.
src/ui/signals-panel.ui holds the panel's shape: the box and its margins, the heading,
the hint that says what a signal is for, and the list. The rows stay in code -- one per
signal, carrying that signal's switch, colour, calibration and drop targets, rebuilt
whenever the stream's signals change -- so the file holds the frame, which is the shape
the plan gives this slice.
The list's width-only size request moved with it, comment and all: a height floor there
made the list occupy 120 px whatever it held, which hid the compact rows' height behind
it.
Read back by a new dump line, `signals panel: labels=2 list=1`, where a lost id reads as
`labels=1` or `list=0` instead of a panel quietly missing its hint; `panels: … row_h=26`
still reads the list's geometry and the height a row takes. check_ui is at 10 ok.
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.
The dump line's two new fields, and what either of them disagreeing with
[stats-probe] on= means: a .ui that lost the widget, or the wiring to it. pane_rows is
what proves the readout rows landed in the frame's measures_list.
The panel's shape -- the title row with its add button, the one statistics switch
the whole panel shares, and the box the readings go into -- now lives in
src/ui/measures-panel.ui. The readings stay in code: each row is a measurement a
user placed, rebuilt whenever the set or the mode changes.
A faithful move, not a redesign: the same margins, spacing, labels, tooltips, flat
classes and insensitive Reset button, the same two lambdas on the same two signals.
The frame is read back through the dump line, which grew the two fields that can
disagree with the code that drives them -- `measures pane: n=4 revealed=0
marks_shown=6 pane_rows=4 pane_w=0 pane_h=0 switch_on=1 reset_sensitive=1`. In that
reading pane_rows=4 is the four readout rows having landed in the frame's
`measures_list`, and switch_on/reset_sensitive are the switch widget and the Reset
button following measure_stats_on, which the probe set through the same signal a user
would. `check_ui` type-checks the file (8 ok, 0 failed) and the build stays at four
warnings.
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().
(7) is done and was the only unticked item: a resize handle per row boundary, and the
weights persisted in the layout file (LayoutState::Row::weight), which is what
'persistent between sessions as the layout' asked for. (1)'s three sub-items are done
too -- intensity_grading is on for this host, a vertical edge is floored by
stage_trace_slopes() rather than graded toward nothing, and the sample dots are
Style::marker_px. (10) keeps eight slices in code; its 'next:' line predated four of
its own entries and is gone. (9) had one clause pasted twice.
Fifteen display strings in the two preference forms were written as GTK mnemonics -- `_Directory`,
`_Server`, `Multicast _group`, `_Theme` and the rest -- but the property that makes GTK read them was
never set, so GTK drew the underscore literally: `_Directory` in the row, not a D with a line under it.
Two switches are involved, FALSE by default in each case. `GtkLabel`/`GtkButton` take `use-underline`;
the rows take `AdwPreferencesRow:use-underline`, "whether an embedded underline in the title indicates a
mnemonic". The two buttons in the source form already set it (so their mnemonics worked and showed no
underscore); the thirteen rows did not. All thirteen now do.
The row classes that carry the property are not all related -- AdwEntryRow has its own, while AdwSpinRow,
AdwComboRow and AdwSwitchRow get it through AdwActionRow -- so the probe reads it by name on a GObject
(g_object_class_find_property, then g_object_get) rather than casting to one row type; a cast to a
`GtkWidget*` where the type is only forward-declared does not compile at all.
`_Cancel` and `_Connect` both claimed C in the same form, so Alt+C could only reach one of them: that
marker was unreachable, which is worse than absent because it is in the source to be trusted. `_Connect`
becomes `Conn_ect`, freeing C for Cancel.
[prefs-probe] reads the count (4/4) on the real widgets; check_ui validates the property against the GIR
for every object in every .ui file, inherited properties included.
The toolbar button was the panel's only input: `update_side_visibility()` derived the
panel from the button and never the other way, so the button went on saying "shown" in
two cases where the panel was off -- while there were no signals to show, and after
anything else moved the split view's state.
Binding the two together is not the fix. AdwOverlaySplitView writes `show-sidebar`
itself, at startup and when it collapses, with no user involved; a binding pushes that
into the button, the button's handler reads it as the user's wish, and the sidebar then
never comes back when a source connects -- a worse bug than the one reported, and one
that a "was this our own write" flag does not catch either, because the toggle's signal
may fire after the write returns.
So the direction is stated instead of inferred: `show-sidebar` is an output, the button
is the only input, and `App::sidebar_wanted` holds the wish between them. The wish is
written by the toggle's handler alone (guarded while we set the button ourselves), the
no-signals case forces the panel off without touching the wish, and tick() re-asserts
both from the wish when the widget disagrees -- so a hide gesture does not stick either.
[sidebar-probe] now reads the pair (shown vs button) in both states and against a hide
that did not come from the button; shown=1 button=1 with a source, shown=0 button=0
without, and the source reconnecting brings both back is the reading this exists for.
The sidebar's width was a GtkPaned divider position: `window - 940` in pixels. On any window
narrower than 940 px the divider landed past the right edge and the sidebar came up 0 px wide,
reachable only by dragging the divider back.
Every attempt that kept the paned failed for that reason -- deriving the position from the paned's
own width, re-parenting the column, property-form children, code-set size requests. The mechanism was
the fault, so it is gone: the row is an AdwOverlaySplitView, which is what a utility sidebar is in
GNOME, with min-sidebar-width = max-sidebar-width = 320 in pixels. Its width is therefore its own at
any window size, and when there is no room beside the plot it *overlays* the plot (collapsed, set from
the window's width in tick()) instead of being squeezed to nothing.
Two things found on the way, both recorded in the invariants:
- sidebar-width-fraction is a 0..1 fraction of the window whatever sidebar-width-unit says. Setting a
pixel count there is a GObject critical and it falls back to 0.25, which is why the sidebar first
read 560. The width is pinned with min/max instead.
- the window opened at its content minimum (756 px, the plot column plus the sidebar) because the
explicit gtk_window_set_default_size() was dropped when the window moved into the .ui. Restored.
[sidebar-probe] reads both states and is the guard: window=756 sidebar=320 under a 2x scale, which is
the case that used to read 0.
`side_w` is the sidebar column's width, and it must be its own request (320) rather than 0. It turned
a report of "I cannot see the right side panel" into `side_w=0` in one run, which is what a reading is
for.
It also shows the shape of the fault: the width is 320 during the first frames and 0 once the window
settles, while the divider sits at 940 and the plot column ends around 752 -- so the paned is not
giving the sidebar any width, whatever the column asks for.
Four attempts to fix that here were each reverted, because each one left `side_w=0`: placing the
divider from the paned's own width instead of an absolute 940, the property form of the paned's
children, re-parenting the column in code, and a code-set size request on the scroller and the column.
The cause is not one of those, and the next step is to read the paned's own width and the column's
parent chain rather than to guess again.
src/ui/cursors-panel.ui holds the panel's shape -- the header with the mode dropdown and the reset
button, and the grid the two cursor times are read in. What is not in it is the grid's contents,
which follow the cursor mode and the rows and are rebuilt whenever either changes.
Panels need a builder that outlives them, unlike the dialogs, which are rebuilt on every opening: a
widget belongs to the builder that built it, so App::ui_builders holds each panel's for the life of
the window. ui_load() is that, in ui_widgets.cpp.
make test-ui also checks that udpscope-ui.gresource.xml lists every .ui file now. That was the third
trap of this refactor -- a file on disk but not in the resource is a Gtk-ERROR at load, which aborts
-- and it is a compile-time mistake that nothing else in the build could see. Verified by unlisting
the new file and watching the check fail, then restoring it.
[cursors-probe] reads as it did: all four modes, pane=1, the timings and the drag cases.
The interface is hand-written GtkBuilder XML and nothing in the build can see a mistake in it: a
property a class does not have, or a child a container does not accept, is a Gtk-ERROR when the
window is built -- and Gtk-ERROR aborts the process, so a typo in a .ui takes the application down
rather than failing to open a dialog. xml-stripblanks catches malformed XML and nothing else, and
the probes catch the rest only for the windows they open. Three of those aborts happened during
this refactor.
tools/check_ui.py round-trips each file through blueprint-compiler: decompile to blueprint, then
compile that, which type-checks every property and child type against the GIR. The XML stays the
source of truth and stays hand-written -- this is a check, not a compiler, and nothing here is
needed to build the application. Which is why the target is opt-in (no ALL) and the tool is looked
for at configure time rather than required: without it the target is absent, not silently passing.
$ make -C build test-ui
check_ui: 5 files in src/ui
ok help.ui ... source-form.ui
check_ui: 5 ok, 0 failed
Injected the exact mistake that cost a run earlier (an AdwEntryRow subtitle) and the check caught
it, with the caret and the "did you mean title?" hint, exiting non-zero. --lint prints the linter's
advice separately: it is advice, and the linter has opinions this project does not share.
src/ui/main-window.ui holds the window, its two panes, the plot column with the status line under it,
and the sidebar's scroller. What stays in code is what depends on the stream: the events pane, the two
plot areas, the sidebar's panels and the status popover, each put into a slot by id.
The header bar is deliberately not in the file. It is the window's own titlebar, every button on it is
wired to an action, and an AdwApplicationWindow refuses a titlebar outright -- a fatal Adwaita-ERROR
rather than a warning that leaves the window merely ugly -- so the window is a GtkApplicationWindow and
the header bar stays where it was.
gtk_paned_set_position() is the other thing that had to stay in code, and the reason is order rather
than shape: it clamps against its children *now*, so stating it before the sidebar's panels exist moved
the plot column by ~180 px.
The layout, events and box-zoom probes read what they read before this change, and the header reads
window_button_w=130 bar_w=756 as it always has -- checked by building the previous commit and running
the same probe against it, because the layout numbers in the notes turned out to be stale from an
earlier session. Five UI files now.
src/ui/source-form.ui is the form a source is added or edited with: an AdwDialog of
AdwPreferencesGroup rows (AdwEntryRow, AdwSpinRow, AdwSwitchRow) with its action in the header bar,
where the label says which mode the form is in -- Connect for a new host, Save for an existing
configuration. The grid of labels and bare entries it replaces had its hints in placeholders, which
vanish as soon as there is a value; they are the groups' descriptions now.
src/ui/help.ui is the help window's chrome: an AdwWindow with a header bar and an
AdwNavigationSplitView whose sidebar is the page list. The rows stay in C++ because the fourteen
pages are data, not template.
Four UI files now, 653 lines of template that used to be widget construction. Two libadwaita traps
cost a run each and are in docs/claude/invariants-gtk-and-chrome.md: an AdwDialog has no content
property (its child is a plain <child>, unlike an AdwToolbarView), and AdwEntryRow has no subtitle
(it is an AdwPreferencesRow, not an AdwActionRow). The unused form_field() helper went with them.
Every probe reading is unchanged -- [sources] form:, [sources] edit form:, [help] -- which is what
refactoring a shape rather than a behaviour should look like.
src/ui/preferences.ui is an AdwPreferencesDialog whose rows are libadwaita's own -- AdwEntryRow,
AdwSpinRow, AdwSwitchRow, AdwComboRow, AdwButtonRow -- instead of a label and a bare GtkEntry in a
GtkBox. There is no Apply button: a row applies as it changes, which is what those widgets are
designed around, and [prefs-probe] reads the settings file back after every change.
The folder chooser is cancellable now, so a picker still open when the dialog closes cannot write
into a row that is gone; the cancellable is also how the probe takes the cancel path without a
mouse.
Two traps cost a run each and are recorded in docs/claude/invariants-gtk-and-chrome.md: an
AdwDialog is not a GtkWindow (it cannot parent a GtkFileDialog, and in floating mode it adds a
native surface to gtk_window_get_toplevels() that is neither a widget nor a window), and a .ui
that is not listed in the GResource is a Gtk-ERROR at runtime rather than a build failure -- which
is exactly what the probe opening every window is for.
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.
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.

The lookup compared raw uint32 counters with >= and <, so a hole spanning the
2^32 wrap matched nothing and every late packet belonging to it was dropped. A
signed delta, the idiom deps/udpsclient already uses throughout.

Four latches were process-lifetime -- two of them function-local statics, so
process-wide rather than per-object -- and a condition that warned once stayed
silent about every later occurrence in a long-lived session. A diagnostic that
goes quiet after the first occurrence is the failure mode worth fixing in a
feature whose job is diagnosis.

rebuild_locked() replaced the store, so produced() restarted at 0 while the
producer's tick_ kept counting: a hole's slot and tick addressing then described
a buffer that was gone, forget_holes_before() could not retire it, and a
backfill's amend fell outside the ring -- repairing nothing while the hole was
still marked repaired, which is the band reporting the opposite of the truth. A
re-plan generation is the signal rather than the stride/channel-count guard,
which a reconnect with an identical CONFIG leaves unchanged. slot_base_ is left
alone: it is relative mode's clock origin and must not walk backwards when the
user retypes the window.

A packet that needed a slot and found none was neither held nor delivered: no
counter recorded it and the consumer reserved a hole nothing could ever backfill.
It now commits the gap to free a slot and takes the ordering decision once more
against the sequence that commit left behind, bounded to one retry; past that it
is delivered in order with the counters it skipped as its `lost`, never flagged
late, because a packet ahead of the sequence has no hole to be looked up by. A
duplicate can now replace its slot at a full ring, as hold_packet's own comment
already promised, and the 20 ms default window is a named constant.

--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.

notify::selected passes a GParamSpec* ahead of the user data and
GtkSpinButton::value-changed does not, so on_math_param_changed read the
pspec as its MathDialog* and faulted on the first field it touched --
which is to say on opening the math editor and picking a source.
The probe missed it because filling the form sets the dropdown to the
value it already holds, and GObject emits no notify for that: a channel
sourcing channels().front() picks index 0 on a dropdown already at 0.
math_probe now opens on a channel sourcing the *last* acquired signal,
which does move the selection, and reads back the source the handler
wrote into the node.

Two complaints, not one: the glitch is a row dropped before any style
knob is consulted, and the thinness is a choice udpscope made and never

own default.

Twelve tasks in five phases, so relative timing ships before any of
the client-side reordering work lands.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The two were asked for together and are one design: the packet counter is what
makes a hole addressable, so relative timing is the coordinate system in which
resequencing is arithmetic rather than inference.

The earlier correction moved the claim rather than fixing it: four places still
said the float-equality test "never fires on a real-valued signal", and a +/-1
square is a real-valued signal -- a standalone check against a band of [1, 1]
fired 19 times, because `inside` is true at +1 and false at -1, so the signal
changes side on every transition.
All four now state the measured behaviour: an exact float-equality test against
the level, which an ordinary signal never satisfies and a signal sitting at the
level satisfies on every transition. Neither answer is a band, which is the
reason the second spin is clamped an increment away rather than the detector
special-cased -- the same conclusion, now resting on a true premise.

A finite trigger_time() only says the edge was accepted; the mode is Capturing
until the post window fills. Every field the report prints is read from
display_snapshot(), whose stamps span x = 0 only once the event is Held, so
reporting on the latch alone raced the capture: leg 2 printed
`measured=nan at0=nan ... mode=1` on one run and the documented
`at0=-0.500907 earlier=-0.498185 mode=2` on the next. The report now waits for
Held under the same poll budget, and says `latched but never held` when it runs
out -- a different defect from `no latch`, so the line names which.
The readings are corrected against three consecutive leg-2 runs and one leg-3
run: `t0` is a rebased stream stamp and varies every run, so it was never an
assertion; `hits=` likewise tracks the arm phase (12 at one arm, 11 at another).
The mode ordinals were wrong -- `mode=2` is `Held`, not `Capturing`. Shapes 2
and 3 are now measured rather than read from the arm code; shape 1 still is not.

--glitch-width defaulted to 0.0, so --glitch-at alone produced no glitch and no
warning — the same class of silent no-op that cost a debugging cycle earlier on this
branch. The default is now 0.002 s (2 ms), matching the standalone probe run.

- 08-trigger.txt: names all four condition shapes and the buffer search; fixes the first
paragraph and 'How to reach it' to match what the panel actually contains (fix 3).
- 10-measurements.txt: adds a Statistics bullet — one observation per recompute, what
resets the history, what does not (fix 3).
- probe-readings.md: re-quotes condition-probe lines with level2= and mode= fields;
corrects leg-2 window geometry (0.2 s / 10 % pre, not 1.0 s / 50 %); moves the
wide-window reason to legs 1 and 3; fixes the search-probe scheduling note
(search_probe calls condition_probe directly; do not also set CONDITION_MS) (fix 6).
- verification.md: corrects shape-2 window geometry to match the code (fix 7).
- invariants-session-and-export.md, README.md: document the measure_stats session key —
position, type, default false (fix 8).

- The comment in `feed_window()` and three companion sites claimed a zero-width band
"never fires, because no sample can be on a different side of it than its neighbour".
That is false: `inside = value >= lo && value <= hi` with `lo == hi == 1.0` is true at
+1 and false at -1, so a ±1 square fires 19 times in 20 samples. The correct reason
the panel refuses one is that it reduces the condition to a float-equality test on a
real-valued signal, which in practice never fires (fix 4).
- `EventDetector::condition()`, `BufferSearch::channel()` and `BufferSearch::condition_`
were confirmed unused by grep and deleted (fix 10).

- A buffer rebuild mid-scan (CONFIG or window change) now calls `search.clear()` beside
`reset_measure_stats()` at both sites; without it the scan kept stale at_/end_ and could
report Done over fabricated hits (fix 1).
- `search_marks_label` now carries `PANGO_ELLIPSIZE_END` so the side pane's minimum width
is bounded; the longest text (~58 chars) was driving the pane width (fix 2).
- `update_measures()` gains a third `accumulate` parameter (no default) so every call
states its intent; the Statistics toggle now passes `false`, stopping the same window
being counted twice and deflating sd on repeated toggles (fix 5).
- `search_jump()` records whether `publish_pause_view()` returned an empty snapshot and
`update_search_panel()` appends "(no longer in the buffer)" to the position label when
it did (fix 9).

place_search_marks() places the selected hit unconditionally to keep it marked when stepping
to it, but the label must distinguish this case from hits that are actually visible on screen,
so it does not lie about what is in view. add sel_off_view to track when the selected hit is
off screen, introduce a shown count that excludes it, and emit a third label case when only
the selected hit is off screen.
The plan's Task 8 named the search probe as its test but never extended it, and leaned on the
exit dump instead -- which stops the tick from Live, where no hit is in view, so it reads
placed=0 for a correct implementation and a broken one alike.
- The statistics label in measures_row() now carries PANGO_ELLIPSIZE_END,
matching the kind label's own treatment, so a long reading cannot widen
the pane beyond its measured minimum.
- The toggled handler on measures_stats_check now returns early when
updating_panels is set; apply_layout() sets updating_panels around its
gtk_check_button_set_active() call and then sets the Reset button's
sensitivity directly, so the loaded state is fully applied without a
spurious schedule_layout_save().
- The measures_row() header comment now names both labels that
update_measures() rewrites and explains the two-line layout.
- gtk_widget_set_sensitive on measures_stats_reset is null-checked in the
toggled handler, matching every neighbouring handler in the file.
