Answers review of 48057d7. The G5k routing fix held; the record still
leaned on ambient state in three places.
TerminalLocal now records the accepted content VIEWPORT. Replay fetched
the current panel_grid_size and returned when it was None --- which is
exactly what a hidden or absent panel produces, so a cancellation could
not finish the drag it was cancelling, and a size-changing cancellation
would have finished against the successor's geometry.
A press that anchors NOTHING no longer arms. The document path returned
Some(Document) unconditionally even when panel_cell_byte found no byte,
and the terminal path returned Local while discarding begin_selection's
answer. Both now report what actually began.
The child rows assert EXACT BYTES rather than a count: a wrong event or
encoding passed the old length checks. The literals are written out
rather than built with the encoder's own formula, which would only
assert that the encoder agrees with itself. G5k(b) pins the ruling that
the SGR framing comes from the record while the modifier bits still
report live state, so its release carries code 4 rather than 0.
New rows: P2's effect half (a refused press reaches no target), P9 (a
document press that anchors nothing does not arm), P11 (a recorded local
completion still runs with the panel HIDDEN, which is what the recorded
viewport is for).
THREE ROWS IN THIS ROUND WERE VACUOUS BEFORE THE MUTATIONS CAUGHT THEM,
and the fixtures now assert their way past each cause. The panel grid in
this fixture is FOUR rows, so content is rows 0..=2: my first P9 and P10
cells were out of grid and refused before reaching the path they claimed
to test, and P9's earlier cell clamped to byte 0 instead of failing to
anchor. Both rows now assert the disposition is Accepted before
asserting anything about the effect.
P10 IS DELIBERATELY ABSENT AND RECORDED AS UNWITNESSED. The
begin_selection gate has no reachable false branch through the daemon:
classify has already established the buffer is the side window's live
terminal, and anchor_at resolves every in-grid cell of a live view ---
measured on the fixture, not assumed. The gate is kept as insurance and
the gap is written where the row would have been, rather than covered by
something that would pass whether or not the gate existed.
P2's effect half is likewise not falsifiable by any mutation I could
construct, because a Refused disposition carries no resolution, so no
path can apply it. That is a stronger guarantee than a test, and it is
stated rather than dressed up as coverage.
Also corrects the last false ledger tense.
