Under the window manager a child renders into a shared texture the
host allocates at the next power of two, while the Window pass carried
a depth texture sized to the pass rect; D3D11 refuses render targets
whose colour and depth views differ in size, so the clear landed (it
goes to the view directly) and every draw was dropped — each hosted
tile on Windows showed only its clear colour, the terminal's blank
rectangle among them. The pass setup now sizes the depth buffer from
the target's allocation when it draws to a texture, from the pass rect
otherwise (a pure helper with tests). The hidden-windows switch is
honoured by the Windows backend on the first show, so a test run stays
off the desktop.
Verified on the box: a hosted terminal's first frame 720 ms after
launch with the prompt in it, a typed dir listed. platform 132 tests;
the windows-msvc target checks.

std's wasm allocator is one global spin lock, so workers that allocate
serialise on it and per-job throughput collapses with the worker count
while the browser main thread starves behind them. Measured on the map
bake in the route web demo: a tile takes 15-20 s with 8 workers and
0.1-0.5 s with 2; the start view completes in 80 s instead of 150 s.
Every web app's pools get the cap through worker_count. It goes when the
thread-caching allocator (ALLOC2) lands.

(cherry picked from commit 59096700d56cd8f3f15724e24129c0b428bf6ae7)
A stdin-loop child stored the host's WindowGeomChange raw and never
recorded the host dpi as the window's native dpi, while the native
path converts every OS geometry through the app's dpi_override and
remaps every pointer. VJ is the app that sets an override (its console
scale shrinks the dpi to fit a tile's height), so under the window
manager it laid out in larger points than the pointer it was handed —
every click landed short — and each host resize re-set the raw host
size under the override, so consoles of the wrong physical size were
drawn into the shared framebuffer over the previous full one: the
stacked stale consoles the user saw. Terminals never showed it; they
set no override.
The stdin arms of every platform now apply a host geometry the way the
native path does (the host dpi recorded, the size converted through
the override) and remap pointer positions with the override scale;
window hit-tests compare in native points. No host-side change: the
crop is per presented frame and the swapchain handoff only bridges a
resize.
Proven hidden under the WM: the explorer tab answers a click, typing
filters the music list, a split and its close re-lay the console out
with no ghosts. platform 128 tests; Linux and Windows targets check.

libs/app_module (makepad-app-module) is the contract (aicontrol §3):
AppModule (id, label, register into an isolate, an OpenSchema, create
into InstanceParts, capabilities), InstanceHandles (an InstanceScope
owner token, the storage jail as a cx.storage namespace, the viewport,
a ReplySink for calls that finish later), a ServiceExecutor addressed
apart from the root, and an OpenSchema that refuses raw paths — a file
is a handle the host issued or nothing. Only types live there.
The WM hosts one (module_host.rs): allocate the isolate, retint its
theme from the palette, register, create — one trusted entry into the
isolate, never a second &mut Cx beside the VM; teardown drops the root
first, runs shutdown in the isolate, frees it. MpModuleView is the tile
for an instance's root, drawing and dispatching with the isolate
INSTALLED on Cx (enter_isolate/leave_isolate, new in widgets) and
gating keys on the WM's focus; a TileHost trait covers both tile kinds
so the desk and the focus logic never ask which. The registry overlay
(apps.rs) links modules per app-* feature; the desktop default stays
Process, switched per app in ~/.makepad/wm/apps.splash or by a dev
--module flag. The bus gains its in-process leg: an instance is an
m<id> endpoint the pane addresses like any other — the leg the web
superbuild runs everything on.
sheets is lib + bin: SheetsModule mints MpSheets{} in the isolate and
answers sheets.summary on its executor; the standalone binary keeps its
Window and F10 overlay behind the standalone feature.
The drive found a platform bug: a shader compiled on a widget minted in
an isolate hit the draw-shader object cache by object index alone, so
an isolate's Button reused the main heap's entry and drew with zero
instance slots. The cache is keyed by (heap, object) in every backend,
and add_instance refuses a zero-slot draw call instead of dividing by
it. Isolate cost, measured (the P2 entry gate): 12 ms and ~8 MB per
isolate, flat to 32 — no pre-warming needed.
Verified by hidden grabs under the WM: /os.launch sheets → an
in-process Sheets tile (no child process), the apps row Desktop ·
Sheets, /sheets.summary answered through the in-process leg, a warm
terminal beside it, F10, close → the instance torn down and its isolate
freed. wm 145, sheets 84, app-module 3, services 33; platform and draw
check for windows-msvc, linux-gnu and wasm32.

Measured on the body node: the Microsoft H.264 decoder accepts MF_LOW_LATENCY and
CODECAPI_AVLowLatencyMode and ignores both; it holds pictures until the DPB it
derives from level_idc is full (six access units in, nothing out until DRAIN), and
appending access unit delimiters changes nothing. With level_idc rewritten to 1.0
in every SPS the DPB is one picture and each picture is emitted as the next access
unit arrives (5 of 6 while streaming, the last on flush). flush() now sends
COMMAND_DRAIN. The captured-stream test replays dumped access units and requires
the pictures while streaming; the keyframe-request check is its own test.

Every Window now carries an AiChatSlot beside the tweaker: zero cost
while off, inert when the window manager hosts the process (the WM's
pane is the chat then), and on the first bare F10 it instantiates the
chat's module root BY NAME — mod.widgets.AiChatOverlay — which exists
when the app links makepad-aichat and calls its script_mod; an app that
does not gets one log line. The overlay slides in from the right over
the body with the WM pane's motion, owns the pointer inside its rect and
the keyboard through its composer, keeps ticking while hidden, and draws
in the window's retained overlay list so it composites over the deferred
body. Requests from outside the tree ride Cx globals, never statics.
An app exposes itself with one call: AiServicePort::open(cx, manifest)
is the hosted transport under the WM and, standalone, an in-process link
parked on Cx (PendingServiceLinks) that whichever chat root is up adopts
into its registry — the overlay today, the superbuild's pane later. The
registry wakes the UI when it sends, so an in-process call is answered
without waiting for a pointer event. NoModel leaves the engine feature
so a build without a model runtime still answers honestly and keeps the
tool console; aichat's engine is a default-on feature.
The bridge: Cx::ai_callback beside tweak_callback, /ai?on=1|0, /ai?say=…
and /ai/transcript (the overlay publishes the transcript as JSON after
each state change), installed by makepad_aichat::script_mod.
sheets links aichat and exposes sheets.summary (name, used range, header
row, selection) through the port: standalone the overlay answers it,
under the WM the bus does.
The local model no longer loads on a registration: its session starts
on the first user line, so an app joining the bus costs nothing.
Verified by hidden grabs: sheets standalone /ai?on=1 → the overlay with
the summary card and no model; F10 closes it; under the WM the sheets
tile shows no overlay and F10 toggles the WM pane. widgets 135 + 4
(two widget_tree find_within tests fail before and after this change),
aichat 33, sheets 83 + 2, services 29; widgets and aichat check for
wasm32.

The Microsoft H.264 decoder answers a VT_BOOL CODECAPI_AVLowLatencyMode with
"VT_UI4 != pValue->vt" (seen on the body node), so send the number. The
Media Foundation encoder opens each access unit with NAL 9, which the
keyframe check now skips.

Trace every ProcessOutput HRESULT/status, keep the first access units beside the
trace so a stream can be replayed offline, ask for CODECAPI_AVLowLatencyMode through
ICodecAPI as well as the MF_LOW_LATENCY attribute, and let the round-trip test plus a
captured-stream replay test run on a Windows box.

The Microsoft H.264 decoder reports output stream flags 0x107 (whole samples,
single sample per buffer, fixed size); reading bit 0 as "the MFT allocates its
own samples" handed ProcessOutput no buffer and every call failed with
E_INVALIDARG — seen in the MAKEPAD_H264_DEBUG trace on the body node.

The live decoder never produced a frame on the body node: MF_E_TRANSFORM_STREAM_CHANGE
was hand-derived as 0xC00D6D60, which is MF_E_TRANSFORM_TYPE_NOT_SET; the real stream
change (0xC00D6D61) was treated as a hard error, the output type was only negotiated
lazily, and without MF_LOW_LATENCY the decoder holds a reorder window a 2-3 frame live
pipeline never fills. Set MF_LOW_LATENCY on the transform, commit NV12 before the first
ProcessOutput, re-negotiate on TYPE_NOT_SET/STREAM_CHANGE/BUFFERTOOSMALL, drain on
NOTACCEPTING, and stamp packets with monotonic 100 ns timestamps. MAKEPAD_H264_DEBUG=<file>
traces packets, HRESULTs, negotiations and frames for headless services.

IOHIDManager claims known wheels and joystick-class devices, parses
them by HID usage (steering, pedals, twist, throttle, hat, buttons) and
hands out an IOHIDDeviceSetReport handle so an app can drive force
feedback from userspace — no kext, no DriverKit. The studio wire learns
RemoteJoystick.

The decode loop returned before ProcessOutput until the output type was
negotiated — but the MFT only reports MF_E_TRANSFORM_STREAM_CHANGE, the
event that starts negotiation, FROM ProcessOutput. A node fed Annex-B
access units never yielded a frame. Now the pump always pulls, a stream
change picks NV12, sets the type and refreshes size and stride, need-
more-input ends the pump, and rows are de-strided on the way out. The
decision is a pure function with a regression test.

Latin (IBM Plex) is the web default, International (adds the CJK and emoji faces) the
desktop default; app_main! records the choice before widgets register, the theme only
registers the selected chains, a glyph miss never starts a load, and the resolved font
resources are emitted as the makepad.font-assets.v1 section for the packager.

The web feature no longer hides the native API; both transport adapters validate
responses through one upper layer with framing headers refused and redirects off;
the platform transport passes a body cap to makepad-network (honoured by the web
backend); the filesystem cache verifies before deduplicating; BaseUrl canonicalizes
and rejects dot segments; ClientLocation is authoritative.

The platform's exploded z-layer viewer consumed F10 before any app saw
it. F10 now belongs to the AI chat (the WM pane and the Window overlay);
the debugger is Shift+F10 and the recorder Ctrl+F10, beside the
designer's F12. The recorder widget gains a hotkey_ctrl setting.

Cx::monotonic_now backs every elapsed and deadline measurement (Instant natively,
performance.now on the web, reachable from workers); dispatch keeps its handler
installed across traps and rejects re-entry without panicking; the studio websocket
worker spawns only when a studio is configured and waits with park_timeout instead of
spinning.
