Restore the larger of the current and remembered offsets, reading further
pages until the remembered offset is reachable. Scroll events that only pin
the body to the end of shorter content no longer overwrite the remembered
offset, and the body disables scroll anchoring so the offset stays a pixel
distance.
Renderers declare sourceLines; a line navigation in a renderer without it,
such as Markdown, is answered without moving instead of staying pending.

Addresses ds-review-bot: the keyboard step now asserts that focus landed on
the sheet overlay before pressing arrows, the comment keeps only the local
why, and the Agent Note carries the measured counts (10 of 11 master runs,
7 of 38 probe runs, 26 of 26 keyboard runs, 10 of 10 local repetitions).
The meeting-sheet step of document-preview.e2e.ts clicked the sheet overlay
at the cell FortuneSheet already selects on mount, so its polls passed before
the click committed, and the press resolved its cell inside a React state
updater that later renders re-execute against the reflowed grid. On loaded
Linux runners that re-execution landed after the first sidebar resize and
committed B1 (the two-column sheet clamps the stale pointer x to its last
column), failing the reflow loop with `expected 'B1' to be 'A1'`.
Select A1 through ArrowRight/ArrowLeft instead: keyboard moves compute the
target from committed state, so a re-executed updater yields the same cell,
and the B1 -> A1 transition verifies the interaction before the reflows.

With no OS-marked default the split button labelled the first registered
application and marked it "(default)" in the menu, but the primary action
still asked the OS to resolve the association again; on Windows that can
prompt or open a different application than the button promises. Send that
application's id explicitly and keep the association path for the case the
Host actually marked a default.
The snapshot scenario now clears the platform's own default marker and
re-enters the file, so the association is read again instead of reusing the
answer already held, and it asserts the launched target rather than only the
labels.
The new no-default scenario cleared the macOS application catalog, which
does nothing on Linux: `gio mime` owns the OS default there, and the
Linux stub never wrote the launch log, so CI timed out waiting for the
application gesture. Clear the marker each platform actually reads, log
launches from both stubs, and compare the launched id against the
platform's own registration id.
The reported defect is the branch where the Shell lists associated
applications but marks none as the default: the split button promoted
"Show file location" to the primary action and hid the applications
behind the menu.
Record that state in the keyless document-preview scenario. The new
golden pins the primary action to the opening control, and the gesture
log asserts the main button opens the file while the menu's marked
default launches the first registered application.
