The dock button's tooltip, the guided-tour menu row's tooltip and the m / g shortcut labels still described a side panel and tabs.

Finding 2 — four builder ids had no null check. `side_stack`,
`side_switcher`, `measure_page` and `signals_page` were resolved at
lines 4709-4712, well past the skeleton null-guard. A typo in the `.ui`
would have been a silent segfault. The four resolutions are moved to
the guard block and added to its condition, in the same form the guard
already uses.
Finding 3 — the 'editable focused: m refused' leg of keys_probe was
deleted instead of ported. It is restored, adapted for the new
behaviour: 'm' now selects the Measure tab instead of toggling a pane,
so the refusal is observed as the side_tab name being unchanged across
the synthesised key, not as a toggle that did not flip. The dump line
keeps its existing name and `refused=` field so probe-readings.md:601
still describes it.
Finding 4 — `exit_probe_step3` assigned `sidebar_shown` to both
`dbg_side_visible` and `dbg_side_column_after_hide`, and the panels:
dump line read the wrong one (dbg_side_visible) for its `(visible=)`
field. Two readings that cannot disagree diagnose nothing. Resolved
by making `panels:` read `dbg_side_column_after_hide` and removing the
redundant `dbg_side_visible` field.
Finding 5 — the three-line rationale comment above `reload_file_view`
in `apply_math_channels` was removed by the commit under review.
Nothing it said became untrue. Restored verbatim from e10a92f.
Finding 6 — three comments the change made false:
- `on_activate`: 'the sidebar's scroller' replaced with 'the sidebar's
tab switcher and two-page stack', matching the actual ui file.
- `update_side_visibility`: 'Hiding the scroller instead left an empty
column where the panels should be' removed; the design it described
no longer exists.
- `header-bar.ui`: 'two of them are toggles' updated to 'one of them
is a toggle'; after signal_toggle's deletion the overflow menu holds
one toggle (layout).

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

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.
