Fix the false trailing clause in the udps_stats_t::late_resequenced comment,
move udps_held_t from the tunable-limits section to internal-state next to
udps_slot_t, and add braces to three braceless if bodies to match house style.

The four original items are done. What replaces them: the invisible
riser, relative timing, named configurations, frame storage for
forensics, opening exported waveforms, the plot context menu, drag
resize, an event cache with replay, and a preferences dialog.

--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
revisited -- it asks deps/plotter for a trace thinner than the library's
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.

- Leg 1: widen to 1.0 s / 50% pre so the square's opening edge is in the snapshot
- Leg 2: use sine (not square) for the window channel, edge = falling so the band exit
is deterministic, and read earlier from vals[end-2] rather than half the snapshot
- Leg 3: raise timeout to 0.3 s (> half-period), accept either crossing direction,
widen to 1.0 s / 50% pre to reach the crossing that sits 0.3 s before x=0

The old `phase=` field compared `trigger_time()` against the mock's absolute
`glitch_at + glitch_width` target. The app's stream epoch is the first packet
it received, not the mock's t = 0; the two clocks differ by however many
packets the CONNECT handshake cost, making the comparison meaningless.
Replace it with a snapshot-relative measurement: scan backwards from x = 0 in
the held event snapshot for the most recent upward crossing of `condition.level`
(the same `prev < level && val >= level` test the detector uses) and negate the
crossing's stamp to get the measured pulse width. A `measured` near 0.002 s is
the glitch caught exactly; near 0.200 s means an ordinary edge was latched.
Remove the now-dead `glitch_at`, `glitch_width`, `square_period` fields from
`ConditionProbe`. No other files changed.

Nine tasks with literal code: the mock's injected faults, the shared
EventDetector the trigger and the search both run, the four condition
shapes and their panel rows, the Welford statistics and what resets
them, the chunked buffer search, its marks, and the documentation.
Every probe's expected reading is written as a shape with the measured
figure left to be recorded from a run, never assumed.

The spec described the new condition fields as appended session keys. LayoutState
carries no trigger field at all -- the trigger is built from --holdoff and the
panel's defaults on every launch -- so there was nothing to append to. Persisting it
is a separate feature nobody asked for, and a session that silently restored an armed
pulse-width condition would surprise rather than help. The statistics toggle stays as
the one session key this design adds.

The spec claimed a window condition with equal levels degrades to an edge trigger on
that level. It does not: the band test is a change of side, so equal levels make the
signal "inside" only on exact float equality and the condition silently never fires.
Special-casing the detector into an edge trigger would conflate two state machines
that answer different questions -- the divergence the shared evaluator exists to
prevent. The panel refuses the degenerate band instead.

Qualified trigger conditions (pulse width with glitch as a comparison, window,
dropout), per-measurement statistics with a reset, and a search over the retained
ring. The first and third are the same question asked of live and of recorded data,
so they share one allocation-free EventDetector extracted out of TriggerEngine --
and the probe that proves the two paths agree on t0 is part of the scope.
Reference waveforms, PNG export, FFT and a byte-bounded event history are out, each
for a stated reason.

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.

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.
