Fixed sample sheet (boxdraw families, blocks/shades/quadrants/sextants, Powerline separators, CJK alignment ruler, 256/truecolor bars) injected via the focus-free ConPTY injector, captured with PrintWindow PW_RENDERFULLCONTENT. First pass: structural parity across the board - boxes closed and seamless, CJK ruler column-aligned, Powerline triangles crisper on the GPUI side thanks to boxdraw geometry. Follow-ups: same-theme comparison after config sharing, real fastfetch once installed, zoomed stroke-weight audit.
Payload mixes ANSI 256/truecolor, CJK, boxdraw and Powerline lines; timing happens inside the session (stopwatch around cmd /c type) so only PTY-consumption speed is measured. Commands are injected via AttachConsole + WriteConsoleInputW - no window focus involved - and the window is made topmost without activation so both shells actually render (the legacy renderer skips frames when fully occluded). First results: gpui-lab within 3.6 pct of winit-old throughput (21.8s vs 21.1s per 50MB) at 28 pct less memory; G1 threshold set at 90 pct on an equal grid. Also caught a real engine bug: the system-conhost ConPTY fallback (no sideloaded OpenConsole/conpty.dll pair) stalls completely under sustained output; fix scheduled in P2.
- SSH proxying resolves per-host > ~/.ssh/config ProxyJump > global;
new jump:<host> syntax (single hop, chains rejected with a clear
error) and a system mode that reads the Windows registry proxy
- Win32 input mode: control keys carry their true KEY_EVENT_RECORD
character so Esc reaches byte-stream readers (Claude Code); focus
reports while active; synthesized modifier key-ups on focus loss;
resize coalescing per channel drain; flagless ConPTY retry; PTY
transport failures surface and tear the session down
- Overlay panels (command palette, launcher, session picker, combobox
dropdowns) share the new ui/overlay_list components; settings row
actions share an outline-button widget
- Settings SSH rows draw per-host OS icons instead of a status ring
- IME cursor-area pushes are deduplicated to stop render-thread stalls
during Chinese input in PowerShell; cache invalidated on focus/IME
changes
- Input latency probes behind NEBULA_INPUT_LATENCY=1
The visual work and the reason the visual work kept regressing, in one pass.
Picker and palette
- Rows drop their card borders: a row is transparent until hover/selection.
Five ringed white rectangles in a column read as a form, not a list, and
the panel-to-row lightness difference already separates them.
- Option paths start at one shared column instead of being right-aligned.
Right alignment floated every row's path START with its own length
(cmd.exe began ~300px right of Nushell's), so scanning meant hunting
left and right per line.
- Footer hints drop their chips. A chip background means "clickable" here;
the arrow/Enter/Esc legends aren't buttons, so key and description
separate by ink weight instead.
Keycaps go back to one chip per combination
Per-key chips are a macOS form, where the modifiers are single-character
glyphs that tile evenly. Ctrl/Shift/Alt are words, so splitting produced a
row of ragged blocks; and Windows users already read Ctrl+Shift+P as one
string in VS Code and Office.
Carets that look alive
The blink phase hung off the wall clock, so a field taking focus had a 50%
chance of showing its caret up to half a second late — which reads as "not
focused". Phase now starts at the last edit: lit immediately, steady while
typing, breathing only after the hand stops, at the system's
GetCaretBlinkTime (including the accessibility setting that disables
blinking). The palette was also missing from the fast-redraw list, so its
caret froze once the open animation ended. The palette caret is now a
1.5px beam rather than a full-cell glyph, which lets placeholder and real
input share one x — the first keystroke no longer shifts the line.
Overlays share one recipe
Confirm dialogs and the SSH editor gain a real drop shadow and the common
radius; both previously drew hairline + fill only, so a dialog demanding an
answer floated lower than the palette you dismiss with Esc. The SSH
editor's dim was a hard-coded 67% black ignoring the theme. Dropdowns cast
a shadow instead of a glow (a glow spreads brightness without establishing
height) and are opaque, since a menu sits directly on the content it hides.
Why this kept regressing
ui/mod.rs has said "layer contract: no magic numbers" for a while, and
widgets.rs violated it — a constraint expressed only in a comment is not a
constraint. ui/guardrails.rs turns three of them into failing tests, each
carrying a budget equal to today's real count: new violations fail the
build, and clearing old ones fails it too until the budget is lowered, so
the number only goes down. This pass: radius 121 -> 94, strokes 69 -> 56,
glow-as-shadow 12 -> 9.
Probe script now runs a COPY of the debug binary. Running the build output
directly makes the next cargo build die with an opaque mingw link error,
and it invites cleaning up by image name — which would kill the user's own
window, possibly the one hosting this session.
- Ctrl+K opens/closes the shell picker (new ToggleShellPicker action, listed
and rebindable in Settings -> Key bindings). It takes over the shell's
kill-line by default.
- The picker is now a card list: a "Recommended" hero card (name, full program
path, Enter chip) plus uniform "All options" cards. PaletteLayout exposes
per-row rects and `row_at`, so hover and click stop lighting up section
captions and the gaps between cards -- both passes and hit-testing read one
geometry instead of dividing by row_h.
- One keycap recipe (display/keycap.rs) shared by the picker's Ctrl+K badge,
the command list's shortcut hints, Settings key rows, confirm dialogs and
the picker footer. Combos split per key; confirm keycaps no longer restack
the button's own fill.
- Light-theme overlays go white-based instead of inheriting a silver fill from
the theme family.
- The palette's right edge measures from a single GUTTER instead of four
different insets; the footer measured from the panel rather than the card
column, which left a ragged margin that drifted with font size.
Session v4 doubles as the workspace file format: tabs persist their full
split tree, per-pane cwds and launch identity (shell/profile/SSH), so both
crash recovery and exported workspaces rebuild real layouts.
Startup now always sizes the window from the config base font at the
standard 116x30 grid: the persisted Ctrl+wheel zoom no longer inflates the
first frame, and the saved window size/maximized state is write-only.
