`move_traffic_light` was framing the close / minimize / zoom NSButtons
at `titlebar_height - traffic_light_position.y - button_h`. Once the
window opts into `NSFullSizeContentViewWindowMask`, the content layout
rectangle covers the whole frame and `titlebar_height()` returns 0 —
collapsing the origin to a large negative Y. macOS still painted the
buttons through its own caching layer at the title bar's natural
position, but the buttons' hit-test rectangle followed the frame off
screen, so clicking close / minimize / zoom did nothing.
Anchor the math against the close button's actual superview frame
height (the themeFrame, which equals the window height in Y-up
coordinates) so the visual position and the hit area stay in lockstep
no matter what mask combination the window opens with. `titlebar_height`
stays available for callers that want the legacy non-full-size
interpretation, with `#[allow(dead_code)]` and a docstring pointing at
this fix.
Drops the separate dashboard tile and the top-level "+" button so the
sidebar's first row holds a single workspace identity. "+ New
workspace" lives inside the disclosure popover next to the existing
spaces list, matching that row's geometry instead of inventing a new
square tile.
The previous 76 px traffic-light reserve only cleared the buttons
when the row also carried the tile and "+" — with the pill alone
plus its drop-shadow, it slid back behind the green button on the
default sidebar width. Widen `TRAFFIC_LIGHT_RESERVE` to 100 px and
document the derivation: pill outer left = `29 + RESERVE`, traffic-
light group right edge ≈ 112 px, so 100 leaves 17 px of breathing
room. Anchor solver and tests track the new geometry.
Pointing the renderer at the site's own `/favicon.ico` was producing
GPUI image-cache errors on every other tab — notion.com redirected
across origins, sites shipped multi-image `image/x-icon` blobs the
PNG/WebP decoder couldn't read, hosts 404'd. Each one logged a noisy
`ERROR gpui::asset_cache: Failed to load asset` line.
Switch `UrlText::favicon_url` to
`https://www.google.com/s2/favicons?domain=<host>&sz=64`. Google's
endpoint normalises every response to PNG, follows redirects on its
side, and serves a `_/` globe glyph for sites without a favicon at
all — same URL shape every browser dev-tools panel already shows
for "favicon" so the fetch is uniformly succeeding.
The wrangler.toml + better_auth.ts move from auth@ to browser@elydora.com
left this assertion behind, so `npm test` failed pre-deploy. Realign
the expected `from` field and the worker's test suite is green again.
Replace the "drop a session token in a file" workflow with a real
Chrome-style email login. The Cloudflare worker already had Better
Auth's `email-otp` plugin wired into `SEND_EMAIL`; this commit
builds the renderer-side counterpart.
Worker side:
- Move the OTP sender from `auth@elydora.com` to `browser@elydora.com`
(wrangler.toml `allowed_sender_addresses` + better_auth.ts
`EMAIL_OTP_FROM_ADDRESS`). Worker must be redeployed to pick this up.
Client side (`ely_sync_client::email_otp`):
- `send_email_otp(config, email)` POSTs `/api/auth/email-otp/send-verification-otp`
with `{ email, type: "sign-in" }`.
- `verify_email_otp(config, email, otp)` POSTs `/api/auth/sign-in/email-otp`,
reads the Better Auth session token from the JSON body's `token` field
with the `Set-Cookie: better-auth.session_token=…` header as the
documented fallback channel, and returns it as a `BearerToken`.
Shell side (`shell/auth.rs` + `shell/internal_pages/sync.rs`):
- New `AuthFlowPhase` (Idle / SendingCode / AwaitingOtp / Verifying /
Error) tracks the in-flight form. Two off-thread workers run the
HTTP exchanges so the GPUI render loop never blocks.
- Successful verify saves the bearer via `SyncEngine::install_bearer`
and triggers an immediate snapshot upload, so the user is signed in
+ initial-synced in one click.
- Sync settings page replaces the bare "Sync now" button row with an
account card: when SignedOut → email field + Send code → OTP field
+ Verify / Resend; when signed in → an account chip + Sign out.
- `trigger_cloud_sync_upload` no longer takes a `Context` param so
the post-auth path can fire it from the inbox-drain pass without
needing a window context.
Two paths in `WebSurfaceStore::tick` were downgrading a perfectly good
Ready frame back to Failed / Loading on every transient hiccup:
- `WebSurfaceRuntimeFrame::Failed` overwrote the surface state
unconditionally. Combined with the 125 Hz tick (which submits a Poll
for every visible tab and any transient ensure / poll error becomes
a Failed response), even one parse glitch wiped the rendered page.
- The `initial_display_gate_message` and `should_hold_initial_frame`
checks for incoming Ready frames hardcoded `has_previous_frame =
false`, so a stray empty paint pass after the page had already
rendered would knock the surface back to Loading or Failed.
Detect whether the surface already has a `Ready(_)` state and:
- ignore Failed responses (logging through `tracing` for diagnostics)
while a real frame is on screen;
- pass that "had ready" signal into the gate / hold checks so they only
apply to the very first paint, not later refreshes.
The page now stays put even when Servo emits a momentary error; only
the first-paint failure path can mark the surface Failed.
The three layout preset cards (Single column / Compact / Hidden on
hover) painted as bright white boxes regardless of theme, never
implemented the layouts they previewed, and duplicated the live
sidebar resize handle which already covers the same intent. Drop
the section, the supporting `appearance_layout_cards` module, and
the chrome `mod` declaration that re-exported it.
The sidebar header stacked a redundant `ELY Browser ⌄` title row above
the workspace picker, pushing the picker down a full 30 px and leaving
the traffic lights stranded over the title text. macOS already advertises
the app name in the menubar, so the in-window title is dead weight.
Drop the title row, reserve `TRAFFIC_LIGHT_RESERVE = 76 px` at the start
of the picker row instead, and recompute the disclosure anchor from the
new geometry. Traffic-light Y from main.rs (`SHELL_INSET + 22`) lines
up with the new picker row's vertical center on the first frame, so the
anchor solver sums one fewer row.
`SyncConnectionState` was a one-variant enum (`SignedOut`), so the
Sync page rendered "Local-only · sign-in coming soon" even after the
bearer token landed on disk and the upload thread completed. The
state machine now mirrors the actual lifecycle.
What lands:
- `SyncConnectionState` gains `SignedIn`, `AwaitingDeviceApproval`,
`SyncReady { last_synced_at_secs }`, `SyncError { message }`.
`SyncObjectState::Synced` joins the per-object enum so individual
rows can advertise "Synced" once a successful upload lands.
- `BrowserCore` stores the current `SyncConnectionState` and exposes
`set_sync_connection_state`. `sync_status` now propagates the live
state into the snapshot the UI reads.
- `ElyShell::probe_initial_sync_state` inspects
`<profile_data>/sync/bearer.token` synchronously at construction
so the first render of the sync page is honest about whether the
user is signed in.
- A `std::sync::mpsc` channel ferries upload outcomes from the
off-thread worker back to the shell; the existing 8 ms tick
drains it and stamps `core.set_sync_connection_state` with the
freshest result. The UI now shows "Signed in · awaiting first
sync", "Synced · last upload Xm ago", "Sync error · …", and the
worker-special "Signed in · waiting for device approval" when the
server returns `device_not_approved`.
Dark mode was persistent in `AppearanceSettings` but never reached any
paint code: every call site in the shell read `colors::INK` etc. as a
`pub const u32`, so toggling `ThemeMode::Dark` mutated state nothing
sampled. Root-cause fix is to invert the contract — the design-system
exports functions that resolve through a thread-local `Mode`, and the
GPUI render impl sets that mode each frame.
What lands:
- `ely_design_system::colors::Mode` + thread-local + `set_mode` /
`mode` accessors. Every ink shade, glass surface, stroke, divider,
hairline, canvas, success / error chip now picks the warm-dark
counterpart when the active mode is `Mode::Dark`.
- `ElyShell::render` resolves `ThemeMode::System` against
`Window::appearance()` and pushes the mode before traversing the
tree, so widgets lower down read the right shade without owning a
`Mode` parameter.
- `render_wallpaper` + `panel_bg` now branch on `colors::mode()` so
the gradient base, panel tint, and overlay highlights flip to
warm-graphite when dark mode is active.
- Mechanical conversion across 687 call sites in 55 files from
`colors::FOO` constants to `colors::foo()` accessors. The
`Theme` / `ELY_THEME` const surface (unused outside the design
system) is removed; the function surface is the new contract.
Now that `LiveRuntimeWorker` does all the blocking IPC off the UI
thread, the 16 ms shell tick is no longer the bottleneck — drop it to
8 ms (≈ 125 Hz) so a 120 Hz display can present a fresh Servo frame
between every refresh. The worker queue still coalesces, so doubling
the rate does not double the wire traffic.
Replace `fade_in`'s linear ramp with an ease-out cubic so panel /
overlay reveals decelerate the way the design tokens promise instead
of cutting in abruptly at the end. Unit-tests pin the curve shape so a
future refactor that wires in a different easing function won't
silently revert to linear.
Wire `SyncEngine::upload_bytes` to a Settings → Sync button:
- `BrowserCore::build_sync_snapshot_bytes` serialises the user's
bookmarks on the UI thread (cheap, synchronous).
- `ElyShell::trigger_cloud_sync_upload` resolves the active
profile data dir, spawns a dedicated `ely-sync-upload` thread,
and lets the engine run the blocking HTTP round-trip there so
the GPUI render loop never stalls on the network — the same
invariant the Servo IPC worker enforces.
- Outcomes go through `tracing` on the `ely::sync` target. Users
drop a Better Auth bearer token into
`<profile_data>/sync/bearer.token` to opt in; without one, the
engine reports `SignedOut` and the click is a no-op.
The Better Auth handshake + device-approval UX still need their
own UI passes; this lands the data-plane plumbing so those pieces
slot in without re-architecting the snapshot path.
Add per-profile sync orchestration to `ely_browser_core`:
- `SyncEngine::for_profile_dir` loads / generates the persistent
device identity under `<profile_data>/sync/device.json` and reads
the bearer token from `<profile_data>/sync/bearer.token`.
- `install_bearer` accepts (or clears) the Better Auth session
token; everything else stays inert until a token is on disk.
- `upload_now(&BrowserCore)` serialises the user's bookmarks into a
stable JSON snapshot, ships it via `SyncApiClient::upload_snapshot`,
and remembers the resulting snapshot id / logical clock / device
for the UI to surface.
- `BrowserCore::visible_bookmarks_for_sync` returns a read-only view
the engine can iterate without touching the in-memory state.
The shell / settings-page wiring that calls `upload_now` ships
separately so this commit stays a pure model-layer change with no
runtime behaviour difference until the UI plugs in.
Build the Rust counterpart to `ely-browser-cloud`: a Bearer-token
authenticated HTTP client with the JSON wire types for the worker's
device + snapshot routes.
What lands:
- `BearerToken` + `BearerTokenStore` so Better Auth sessions persist
per profile data dir with atomic rename writes.
- `DeviceIdentity` (UUIDv7 + Ed25519-shaped public key, persisted
alongside the token so the worker keeps the same `device_id` across
restarts).
- `SyncApiClient` with `register_device`, `list_devices`,
`upload_snapshot`, and `download_snapshot` over `ureq`, mapping the
worker's strict error envelopes onto typed `SyncClientError`s.
- `SnapshotPayload` enforces the worker's 10 MiB / SHA-256-hash
contract before the wire encode, so callers fail fast.
Out of scope for this commit: the BrowserCore integration that swaps
snapshots in and out, and the in-app Better Auth + device-approval UX.
Those land in subsequent commits — `cloudflare/src/api_controls.ts`
rejects sync from devices that aren't already approved, so first-use
also requires a one-shot D1 approval until that path exists in the UI.
Servo already publishes the live page title in every `LiveFrameReport`
but the renderer was dropping it on the floor — tabs that navigated
away from `ely://new-tab` kept showing "New Tab" forever, and there
was no favicon visible anywhere in the sidebar.
Add `BrowserCore::set_tab_title` and switch `set_tab_favicon_key` to
return `Ok(true)` only when the value actually changed; both methods
mirror the new value into the matching history entry so the History
page stays in lockstep. Derive the canonical `/favicon.ico` URL from
the loaded URL on `UrlText` and store it as the tab's `favicon_key`.
In the surface layer, every Ready frame now emits a
`WebSurfacePageMetadata` change alongside any `WebSurfaceUrlChange`,
and the controller applies title + favicon URL together. Render the
sidebar tab row's favicon via GPUI's HTTP image loader (falling
through to the URL-derived glyph for `ely://` pages, file URLs, and
hosts without a /favicon.ico endpoint).
Root cause of the post-tab lag: the GPUI 16 ms timer was calling
`WebSurfaceRuntime::ensure_tab` and `tick` on the UI thread, and each
call did a synchronous `serde_json` write plus `read_line` against the
Servo sidecar over stdin/stdout. With even one visible tab, every
frame stalled on cross-process IPC.
Introduce `web_surface_worker.rs` — a per-profile worker thread that
owns the `ServoLiveClient`, drains a coalescing request queue
(latest Ensure/Poll per tab wins, no unbounded growth), and ships
results back through a `std::sync::mpsc` channel. `WebSurfaceRuntime`
now submits work non-blockingly and drains responses in `tick`; the
UI thread never blocks on the sidecar.
Adjacent in-flight cleanup riding along: hardware IOSurface
rendering-context completion (sidecar `live_protocol`,
`hardware_rendering_context`, GPUI BGRA surface shader), CSS viewport
size + device pixel ratio plumbing into `ServoLiveFrame`, and the
Send opt-ins for `CVPixelBuffer`-bearing types so frames can cross
the thread boundary.
`webview.paint()` dispatches a render command to Servo's paint thread
asynchronously, so the subsequent `read_to_image()` raced the paint
thread and reliably returned cleared-white pixels on data: URLs (T10.8).
Clear `has_pending_frame` before dispatching paint, then spin the Servo
event loop until `notify_new_frame_ready` re-arms it or 32 ms elapse
(override via `ELY_PAINT_BARRIER_MS`). Bench: software path now ships
real RGBA bytes for 60 frames instead of all-white.
Boots release ely_app, waits 8s, screencaptures full screen, verifies:
- file >10KB, dims >100x100 via sips
- center 128x128 patch not ~white (via sips crop + stdlib PNG decode)
- stderr captured to /tmp/ely-verify-stderr.log on crash
Runs idempotently (kills stale ely_app on entry + trap cleanup on exit).
No new deps; pure bash + macOS sips + /usr/bin/python3 stdlib.
First real run: PASS, screenshot /tmp/ely-verify-20260511-005449.png,
center RGB ~(243,240,236) — app chrome paints, but web surface still
shows the GPUI welcome panel (no Servo content) — exactly what T15's
paint barrier should fix.
T10.1: with the vendored `HardwareOffscreenContext` (048c5df) and the
host-level kind dispatch (a7d3e89) in place, the sidecar binary
still ignored the rendering context kind — every spawn was wired to
the software path regardless of how the host process was built. This
commit threads the choice end-to-end:
* `ely_servo_sidecar` learns a `--rendering-context [software|
hardware]` flag on its `live` subcommand. `LiveArgs` carries
the parsed `RenderingContextKind` (defaulting to `Software` so
existing invocations stay bit-identical) and `live.rs::run_live`
routes it through to `SoftwareServoHost::new_with_config_dir_and_kind`.
Unknown values produce a typed
`SidecarArgsError::InvalidRenderingContext`; a missing value
after the flag produces the existing `MissingArgumentValue`.
* `ely_app` reads `ELY_SERVO_RENDERING_CONTEXT` (with values
`software` / `hardware`, case-insensitive) and, if set, appends
`--rendering-context VALUE` to the sidecar command line.
Unset or unrecognised values fall through to the sidecar's own
software default — a stale env var or a typo never breaks the
browser startup. The sidecar arg parser is the source of truth
for legality of explicit values; the env helper only gates
which values reach it.
* Five new unit tests in `args::tests` pin the new parse paths:
default-is-software, explicit-software, explicit-hardware,
bogus-value-rejected, missing-value-rejected. Run via
`cargo test -p ely_servo_host --features servo-engine --bin
ely_servo_sidecar` and now hit alongside the five existing
snapshot tests for 10 passes.
End-to-end perf expectation: with the sidecar binary built using
`--features servo-engine,hardware-render` and the env var set to
`hardware`, every spawned sidecar webview rasterises through the
real GPU adapter (via the vendored
`HardwareOffscreenContext`/surfman/CGL chain on macOS). The host
still reads back RGBA into a `Vec<u8>` for the existing pipe
protocol; the IOSurface zero-copy bridge that deletes that
read-back is T10.2–T10.5 in docs/t10-iosurface-plan.md and lands
in subsequent commits.

`HardwareOffscreenContext` was vendored in 048c5df but the host's
per-webview `new_rendering_context` still hard-wired
`servo::SoftwareRenderingContext`. This commit threads a
`RenderingContextKind` enum through the host so existing call sites
keep their software path, and new callers can opt into the hardware
path through `SoftwareServoHost::new_with_config_dir_and_kind(...)`.
Three changes, kept tightly scoped:
* `runtime.rs` gains a public `RenderingContextKind { Software,
Hardware }` enum and a new constructor that takes it. The
existing `new` and `new_with_config_dir` keep their signatures
and default to `Software`, so the sidecar binary and the
integration tests pick up zero behavioural change. The
private `new_rendering_context` moves from a free function to a
`&self` method so it can read `self.rendering_context_kind` and
dispatch — `Software` constructs `SoftwareRenderingContext` as
before, `Hardware` constructs the vendored
`HardwareOffscreenContext`. When the `hardware-render` feature
isn't compiled in, the `Hardware` arm returns
`ServoHostError::HardwareRenderUnavailable` instead of silently
falling back; the new constructor also rejects the request
up-front before touching the global Servo runtime flag.
* `error.rs` gains `HardwareRenderUnavailable` so the wrong-feature
path is a typed error, not a panic.
* `lib.rs` exports `RenderingContextKind` alongside
`SoftwareServoHost` so downstream code (next commit will be the
sidecar's `--rendering-context` CLI flag and the live.rs
plumbing) can name the variant directly.
This is purely an extension point — no existing call path changes,
no existing test asserts on the new enum. The next commit will add
the sidecar CLI flag and wire `live.rs::run_live` to pass the kind
through to the host so users can pick the path at startup. The
follow-up commits then extract the IOSurface from the hardware
surfman surface and bridge it across the IPC channel to GPUI's
Metal renderer, deleting the host-side `Vec<u8>` from the per-frame
hot path entirely (full plan in docs/t10-iosurface-plan.md).

The first concrete step toward the T10 IOSurface zero-copy path
(plan in docs/t10-iosurface-plan.md). Before this commit the sidecar
process could only use `SoftwareRenderingContext` — CPU rasterising
plus an 8 MB RGBA readback per 1080p frame is most of where scroll
latency comes from after the file pipe (a80d039), Vec clone
(e02c0fd), texture dedup (7f3b8b4), and hash swap (3f184ee) have
all landed.
The blocker is purely architectural: `servo-paint-api 0.1` exposes
`OffscreenRenderingContext` only as a child of
`WindowRenderingContext`, which requires a `DisplayHandle +
WindowHandle`. The sidecar has no window. The underlying
`SurfmanRenderingContext` glue *can* drive a hardware adapter
against a `SurfaceType::Generic` offscreen surface, but its
constructor is private. Until the upstream PR lands, this commit
vendors the minimal slice of that glue into `ely_servo_host`:
* `HardwareOffscreenContext::new(size)` uses
`Connection::new() → create_adapter()` (real GPU, not the
software adapter) and a `SurfaceType::Generic` offscreen
surface. On macOS the surfman CGL backend backs that surface
with an `IOSurface` — exactly the thing the IOSurface bridge
in subsequent commits will reach for.
* Implements `servo::RenderingContext` so it slots into
`ServoBuilder::rendering_context` wherever the existing
`SoftwareRenderingContext` does, with no other Servo-side
knowledge.
* Scope deliberately narrow: only the methods Servo's headless
readback actually calls. `create_texture` /
`destroy_texture` / `connection` / `refresh_driver` fall
through to the trait's `None` defaults. `read_to_image` inlines
the upstream `Framebuffer::read_framebuffer_to_image` helper so
we don't reach for a private helper that may change shape.
* No `RawWindowHandle` and no `RefreshDriver` — both belong to
paths the headless sidecar doesn't take.
The whole thing is feature-gated on `hardware-render`. Default
builds compile zero new lines; the additional surfman / gleam /
glow / euclid / image / log deps are all `optional = true`. Sidecar
binary still uses `SoftwareServoHost` until a follow-up commit
threads the new context in behind a CLI flag.
A smoke test at `tests/hardware_rendering_context.rs` constructs
the context. On a host with a real GPU it returns `Ok`; on a no-GPU
CI host it logs the surfman cause and reports `ok` rather than
failing the suite — the test is guarding the wiring, not the
hardware availability. On this Mac it constructs cleanly.
The `expect_used` / `unwrap_used` workspace lints are honoured —
fallible reads return `None` instead of panicking, no `.expect()` /
`.unwrap()` survives in the vendored body. The two `unsafe` blocks
(loading GL function pointers via surfman's `get_proc_address`) are
the same blocks upstream uses, with `#[expect(unsafe_code)]` to
override the workspace `unsafe_code = "deny"` lint locally.

Pre-existing `manages_real_servo_webview_lifecycle` failure on
servo.org is unrelated (reproduces on b8795bf without this change,
already documented in T7's commit history).
Two T10-flavoured changes in one commit, each independently ship-able
on its own:
1. `web_surface_frame::rgba_hash` switches from std's
`DefaultHasher` (SipHash13, ~1.5 GB/s) to `ahash::AHasher`
(~10 GB/s). At 1080p (8 MB per frame) the dedup key drops from
~5 ms to ~0.8 ms per cache-miss frame, returning roughly 25 % of
the 16 ms scroll budget that was being spent hashing the
newly-arrived RGBA payload. ahash was already in the dependency
graph transitively via hashbrown, so this only adds a direct
`ahash = "0.8"` line and one Cargo.lock entry.
2. `docs/t10-iosurface-plan.md` records the full architectural
roadmap for the actual zero-copy path that supersedes the
software-pipe pipeline: `OffscreenRenderingContext` against a
hardware surfman adapter, IOSurface-backed surface on macOS,
mach-port handoff to the GPUI process, MTLTexture import as an
external sampler. The document explains why each currently
shipped commit (`840255f`, `a80d039`, `e02c0fd`, `7f3b8b4`, plus
this hash swap) is a stepping stone that eventually deletes
itself once the IOSurface path lands, and names the upstream
API gap in `servo-paint-api` that blocks step 2.
cargo test --bin ely_app: 120 passed, 0 failed, 2 ignored.
Hash collision probability remains ~1 in 2^64; AHash uses the same
keyspace as the previous SipHash13.
Three new diagnostics narrow T7 to test-mode infrastructure:
1. `diagnose_t7_hitbox_reachability_heatmap` (ignored, --nocapture):
builds the real ElyShell, navigates to https://example.com/, then
sweeps a 6×6 grid across the full 1920×1080 window dispatching
mouse_move at each cell and recording hover_point. Result: **0 of
36 grid cells trigger hover_point** — input_overlay's listener
misses every position in the window, not just the viewport center.
2. Same test then dispatches a single MouseDown at the viewport
center and reads back `focus_handle.is_focused`. Result: **true**.
The root div's `track_focus` MouseDown bubble handler fires on
the very same event. GPUI dispatch IS working at the root hitbox
(`.size_full()`).
3. `baseline_overlay_after_gpui_component_init_receives_click` and
`baseline_overlay_with_input_state_construction_receives_click`:
replicate `gpui_component::init` and `InputState::new` +
`subscribe_in` in isolation. Both still pass — neither breaks
hit_test for an occlude div.
Together these isolate the failure to *something `ElyShell::new`
configures that interacts badly with `TestAppContext`'s simulated
executor*, after every individual ingredient passes. The user has
already confirmed (in the previous round) that "click works" after
the layout fix in 840255f lands in the real binary; the T7 red
guard is reproducing a test-mode quirk, not a production regression.
The red guard stays in the suite as documentation. Its `#[ignore]`
reason now records the diagnostic outcome so the next reader doesn't
re-walk the same bisect. Two paths forward (recorded in the
attribute):
(a) reproduce the bug outside TestAppContext and file upstream
(b) route web canvas input through the root div + a viewport-bounds
gate, which sidesteps hit_test for input_overlay entirely
(b) is structurally more complex than it looks because backdrops
(workspace disclosure, hidden-sidebar overlay) sit in z-order in
front of input_overlay and don't `stop_propagation` — implementing
a clean root-level fallback requires teasing apart the cases. Not
done in this commit.

cargo test --bin ely_app -- --ignored: 1 fail (T7 red) + 1 pass

`LiveOutcome::frame` was carrying the rendered bytes as a fresh
`Vec<u8>` cloned out of `RenderedFrame::rgba_bytes()`. At 60 fps
on a 1080p canvas that was an extra 8 MB allocation + memcpy per
frame on top of the clone `host.last_rendered_frame()` already
paid for. `LiveOutcome` now carries the owned `RenderedFrame`
directly, and `write_outcome` writes its `rgba_bytes()` slice
straight to stdout — same single-clone cost as the host already
incurred, no second allocation.
Small Karpathy-style follow-up from the T8 review ("the host
still copies its rendered buffer to a transient Vec<u8> before
write_all; expose &[u8] straight to write_all once the profile
shows that allocation in the top five"). Profile data is still
deferred (T9 was marked vibe-benchmarking until T10 lands a real
spec), but removing the cheap clone is structurally cleaner and
makes the dispatch path one allocation lighter regardless.

T13 (the still-red `user_click_in_rendered_web_canvas_reaches_input_pipeline`
guard) is now backed by five bisect probes that each reproduce one
slice of the real ElyShell render tree and assert the listener combo
still receives a simulated click. Every probe passes:
* baseline_overlay_div_receives_simulated_click — GPUI primitives
* baseline_overlay_with_full_listener_combo_receives_click — exact
listener combo (on_mouse_down + capture_any_mouse_up +
on_mouse_move + on_scroll_wheel) on a single .occlude() div
* baseline_overlay_under_overflow_hidden_relative_receives_click —
the relative + overflow_hidden wrapper render_web_surface uses
* baseline_overlay_under_full_elyshell_wrapper_chain_receives_click —
root → absolute-flex container → main-pane → content-wrapper
→ surface-wrapper chain
* baseline_overlay_with_canvas_sibling_receives_click — adds the
canvas viewport_tracker sibling
* baseline_overlay_with_entity_update_in_mouse_down_receives_click —
on_mouse_down's bubble fires entity.update (auto-notify) before
MouseUp dispatches
* baseline_overlay_under_root_with_track_focus_receives_click —
the full chain wrapped in a root div with track_focus +
on_mouse_up(Left, bubble)
The red guard meanwhile reports `hover_point = None` after
`simulate_mouse_move`, meaning input_overlay's `on_mouse_move`
also never fires — so the failure mode isn't capture-specific.
ALL of the overlay's listeners share the same `hitbox.is_hovered`
check, and it returns false in the real ElyShell tree but true in
every probe. Whatever the difference is, it is in
`ElyShell::new`'s setup (BrowserCore, Entity<InputState>,
SliderState, subscriptions, `start_external_web_surface_timer`'s
detached task) or in the `sync_address_input` call that
`navigate_active_tab` runs through Input's `set_value` — none of
which the probes touch.
The probes stay in the suite as both documentation (they encode
what is *not* the bug, narrowing the search for the next round)
and as regression guards (a future change that breaks them is a
real new regression in plain layout, not in the still-elusive
ElyShell-specific bug). Tests run as 118 passed + 1 ignored;
`cargo test -- --ignored` continues to fail with the same T7 red
guard. T13 is intentionally still in progress.
WebSurfaceFrame::from_parts was unconditionally calling
Arc::new(RenderImage::new([image::Frame::new(image_buffer)])) on
every live frame, even when the underlying bytes were
byte-for-byte identical to the previous frame. At 60 fps on a 1080p
canvas that was ~960 MB/s of host-side cloning plus a fresh GPUI
texture allocation on every tick — the bottleneck Linus + Karpathy
+ Jony flagged as the next material step after dropping the
file-system pixel pipe (a80d039).
A thread_local single-slot cache in web_surface_frame.rs now keys
on a 64-bit DefaultHasher of the raw RGBA bytes. On a cache hit
the existing Arc<RenderImage> is reused; on a miss the buffer is
built once, stored, and returned. Steady-state idle pages stop
churning the GPUI texture pool entirely. Hash collisions are
1 in 2^64 — if that ever becomes a real worry, the cache key can
be widened to length + a sample of bytes before paying the full
memcmp; not worth doing today.
The T10 red guard
(identical_live_frames_share_render_image_arc) drops its
#[ignore] attribute outright per the contract it documented.
The T7 red guard (user_click_in_rendered_web_canvas_reaches_input_pipeline)
remains ignored — it's a separate diagnosis tracked under T13.
cargo test --bin ely_app: 113 passed, 0 failed, 1 ignored
(was 112+2, T10 guard went green).
cargo test --bin ely_app -- --ignored: 1 failed (only T7 click
pipeline remains red).
Follow-ups (left for the endgame T10 IOSurface path):
* a per-tab cache would prevent multi-tab switching from
thrashing the single slot; defer until a real multi-tab
scroll benchmark shows it matters.
* the endgame is OffscreenRenderingContext + IOSurface so the
GPU texture itself is the source of truth and the host-side
Vec<u8> + ImageBuffer + RenderImage allocation chain
disappears entirely.
Every `WebSurfaceFrame::from_live_frame` today calls
`Arc::new(RenderImage::new([image::Frame::new(image_buffer)]))`
unconditionally — even when the underlying RGBA bytes are
byte-for-byte identical to the previous frame. At 60 fps on a 1080p
canvas that is roughly 960 MB/s of host-side cloning + a fresh
GPUI texture upload, and the roundtable agreed it is the next
material bottleneck after the file-system pipe (a80d039).
The contract this test pins is the cheapest invariant we can hold
against today's `SoftwareRenderingContext`: two `ServoLiveFrame`
inputs whose `rgba_bytes` are bit-identical must produce the same
underlying `Arc<RenderImage>` instance. Today they do not; the
ignored run confirms two distinct pointer values for back-to-back
identical inputs.
The fix has two recognised shapes. The interim shape lives entirely
in `WebSurfaceFrame::from_parts`: remember the previous frame's
bytes (hash or pointer-eq) and reuse the existing `Arc<RenderImage>`
when they match. The endgame shape removes the host-side image step
entirely — `OffscreenRenderingContext` + IOSurface — at which point
the assertion becomes meaningless and is replaced by a frame-time
budget. Whichever lands first, the fix commit MUST delete the
`#[ignore]` attribute outright; toggling its reason is a broken
contract.
To call `WebSurfaceFrame::from_live_frame` from a unit test without
spawning a real sidecar process, `ServoLiveFrame` gains a
`#[cfg(test)] pub(crate) fn for_test(...)` constructor that wraps
the existing private `from_parts` with realistic defaults. No
production path uses it.
cargo test --bin ely_app: 112 passed, 0 failed, 2 ignored.
cargo test --bin ely_app -- --ignored: 2 failed (expected RED:
T7 click pipeline + T10 texture re-upload).
