sheets: read_range (one cell or an A1 rectangle, up to 2000 cells, rows
as tab-separated display values), find (case-insensitive over the used
range, 50 hits), write_cell and set_range (Act) — edits go through the
same commit path as paste and direct entry, so recalculation, undo and
the chrome all see them; the module executor answers the same tools.
files: mkdir, rename (a bare name, no separators) and trash (into the
app's own trash dir, never a delete) — Destructive, so the router shows
a confirm card first; every path through the jail, on the demo VFS as
on disk. Written by the delegate from the existing shapes; sheets 88,
files 158 tests.

Driven native, one app at a time, with the assistant up at boot:
terminal, files, task and browser warm-adopted; sheets, image, video
and pdf launched cold; sheets also as an in-process module; the tools
answering through the pane (os.list/launch/close/open, files' listing,
a refused jail escape, a treemap, sheets' summary both ways).
What broke and is fixed: when a window closed or a client died the
layout's automatic refocus took the keyboard from the OPEN chat, so an
os.close typed in the pane sent the next console line into a sheet —
the refocus now leaves the keys with the pane while it is open (a click
on a tile still moves focus, through focus_client). A warm spawn that
cannot start (an installed layout without the binary) counts as a crash
so the pool gives that app up instead of retrying every tick. browser
and sheets link the WM API: a title in the bar and a polite close on
CloseRequested; aichat quits on CloseRequested (the desktop going down).
Measured (WM log, launched → first flip): warm-pooled apps 25–50 ms;
cold launches through cargo's freshness check 0.7–3.7 s (up to 14 s
under a parallel launch's target lock); the same binaries run plain
0.3–1.5 s after macOS has scanned them. wm 148, sheets 84, aichat 2.

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.

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.

apps/files, apps/sheets, libs/wm_api, libs/wm_theme and the renamed env vars and script
namespaces meet the demo seams; added demo files move to the renamed paths; the files app
keeps its own makepad_home so demo builds without the chat feature do not link the AI hub.

Packages are makepad-<name> with the short name as the binary. Env vars
follow (MAKEPAD_WM_*, MAKEPAD_FILES_*, MAKEPAD_TERMINAL_*), config moves
under ~/.makepad/<app>/, the theme namespaces are mod.wm_theme and
mod.browser_theme, the hosted AI envelope key is wm_ai. platform/video
becomes makepad-platform-video so the video app can be makepad-video.
Carries the Score entries that were pending in the WM's curated table.
