mark_hover is gone
Open point 6 of docs/render-pipeline.md: notice words are Look and Exec
targets, so the hover affordance headers have is back on notices, painted
once in the notice's layer and joined into the grid from it. Deleted:
Surface.mark_hover, Cell.hover and render's per-frame reset of it, none of
which had been set since stage 5 (macOS loses its glass hover rect; its
build is ignored for now). Snapshot goldens unchanged.
Shared files touched: macos.zig (the hover bit's removal). Not touched:
pardes.zig, Messages.zig, mouse.zig, gui.zig, detached/*.

Tier 4 draws notices over every group; while a pane closes, a notice goes
back to its own pane's group instead, so the tombstone sliding over it
covers it as it did before stage 8. Review follow-up to stage 8.
Shared files touched: gui.zig.

Stage 8 of docs/render-pipeline.md. The frame is drawn in groups: tier 0,
one per track in paint order (tiers 2 and 3), tier 4 (notices, then guides
and the debug box), tier 5 (bar cursors), each cells, images, decor. Decor
(rules, rails, thumbs, grip marks, spines, the workspace and column rules,
the bottom band, notice rules, bar cursors) is whole-pixel rects through
the new decor.frag over ui.vert, so it carries its track's transition and
clip. A closing pane's chrome comes from Surface.previous_regions.
Deleted: taglineBaseRgb, topbarPaneBorderHeight, bottomTaglinePresent,
frameChromeBg, cellBackgroundIs and the rail inference, paneGripCell's
scan, transient_on, PaintPlan. One cover map (coverFrame) is marked from
the layers and regions once a frame. New regions column, guide and debug;
Surface.chrome is the palette, carried in wire v8 (not shipped yet), so an
attached GUI draws the same chrome (test). A per-instance clip replaces the
vertical transition's scissor.
Goldens: 01-12 byte-identical. 13-17 differ only past the grid: the image
pass left its scissor at the grid's size, cutting rule ends, rail feet and
the bottom band in the leftover pixels whenever a picture was on screen.
16-debug now shows the debug box, which a context-row layer had hidden.
18-mid-transition is new: virtual clock (PARDES_TEST_CLOCK in the GUI),
PanelSlide Newcol with the picture, frame 6 of 12.
Also: the GUI sleeps when idle instead of polling every 16 ms, and a
minimized or occluded window sleeps through animation. Tracy 'gui frame
build' at 200x60: 992/1015 us median before, 989/987 us after.
Shared files touched: pardes.zig (one export), detached/client.zig,
detached/server.zig, detached/wire.zig (all additive), gui.zig. Not touched:
Messages.zig, mouse.zig, tagline.zig, colors.zig, tty.zig, host_io.zig,
dump.zig, exec.zig, panes.zig.

of rows; wire v8
src/Layer.zig merges TagLayer and BodyLayer. `rows` (0 = no layer) and a
cursor at {x, y}. A tag of N rows is ONE layer of N grid rows: tagHit answers
the row as `line`, bodyHit keeps its meaning, and the per-line layer bases
(TAG_LINE_LAYER_BASE, HEADER_LINE_LAYER_BASE) are gone, not aliased.
Wire v8, the one bump: tag layers carry rows and cursor y, and the frame
carries the placed region list. v7 and v9 peers are refused in both
directions (server test over both, a new frontend test over both).
web: tag_layer_value 11 = rows, 12 = cursor y; app.mjs lays every row.
macOS: the Zig side compiles against Layer; pardes.h still sees one row
per tag layer (accepted, the macOS shell is ignored for now).
No visual change: snapshot goldens and the 17 GUI goldens byte-identical.
Shared files touched: pardes.zig, Messages.zig, gui.zig, macos.zig,
detached/client.zig, detached/server.zig, detached/wire.zig (plus web.zig,
app.mjs, edit.zig, look.zig). Not touched: mouse.zig, tagline.zig,
colors.zig, tty.zig, dump.zig, exec.zig, host_io.zig, panes.zig.

joinBody replaces the second paint of a file body with compact tree-sitter
context rows: the body is painted once into its body layer (more rows than
the grid has) and the grid's body rows are copies of the layer's first
ones; the rail is the grid's alone, from its region. Which rows are context
rows is still decided by a text build before the paint, and a body without
them reuses that text and paints straight onto the grid: every other body
has no row the grid cannot show, so it gets no layer and no copy.
Each part now paints only its own rows. The tag paints the tag rows of
every pointer sweep that crosses them (the select sweep in the tag's
colours, the look-hover affordance over it, a middle or right sweep over
both in its button's tint), which the body used to paint over the tag on
the grid alone; the body paints only body rows, and a select sweep begun on
the tag marks the body rows it crossed before the text is laid down, as it
did. Grid and layers agree, the snapshot goldens are byte-identical, and a
test checks the joined grid rows and caret against a plain paint of the
same body with the tag on top and at the bottom. The GUI goldens gain a
terminal pane scene.

A shell now answers Host.now, its monotonic clock in ns, and the pump
advances core animation to it: one .tick per whole 16 ms frame since core
time last stood still. The same animation therefore takes the same time at
60, 120 and 144 Hz, over ssh and after a slow frame (the GUI's re-armed
clock ran them ~25% slow at 144 Hz; the tty's post-frame sleep drifted).
nextWake() lists every core animation in one place: a frame from now while
anything moves, the end of the wait while something only waits (a message
lingering, the look-hover delay), null when idle. Shells sleep exactly that
long, and a wait is jumped to its end in one step, so an 800 ms linger
costs one frame instead of fifty. An overshoot under 1.5 ms after a step is
let go: at 60 and 120 Hz every display frame takes exactly one step (a 16 ms
frame against a 16.67 ms vsync would otherwise double-step every 24th).
The six tick drivers are gone: tty's timer thread only times the wait,
interruptibly (a newer, shorter request cuts short a sleep still timing a
longer one); the GUI's
AnimationClock, web's JS tick bank (pardes_tick now takes rAF's timestamp),
the detached server's and the board's ticks; grid mode steps a virtual
clock straight to each wake. PARDES_TEST_CLOCK, set by the snapshot
harness, gives tty and the detached server the same virtual clock.
Every stepped frame is drawn. The old pump never drew the last frame of a
fade (a .tick asks for no frame, and the fade was over by the check), so a
theme switch stopped at 9/10 of the way until the next input: theme.golden,
themesel.golden and the GUI's acme-light scene move to the theme's true
colours, and nothing else changes. The frozen previous grid is captured only
while a panel transition is chosen, not on every idle frame.

Designed by two agents (a designer and an adversarial reviewer) and not yet
implemented; implementation starts in stages, each its own change.
