Every runtime command acts on the device bound to this worktree, and nothing else attached to the same dev server, and says which device it acted on.

This PR makes the device bound to this worktree the scope of every runtime read and of smoke, with or without a platform flag.

Stack: #202 → #203 → #204 → #206 → #217 → #218 → #207 → #200 (this is 4/8).

Problem

N2-33: a worktree bound to an iOS EAS session ran runtime:tree, which read a local iPhone 17 Pro app with the same bundle id and named the session as the device it read. N2-30: on the same kind of worktree, runtime:tree --ios refused with "No app connected" while the session's app was connected.

Fix

The scope is this worktree's local binding on the run's platform while its lease is live, else the one live cloud binding, else the flags. A shut-down bound simulator has no app, so a read refuses and names it, and smoke boots it. On Android, the run reads the app whose device name carries the bound serial's model, in the spelling adb devices -l uses (Pixel 9 is model:Pixel_9). With two devices of that model, only the one that alone reverses the port is read. An EAS Simulator Android session skips an app on an attached emulator of its model. A wait asks adb reverse again for a changed list, so a twin that attaches mid-run cannot authorize a read. One function, silentTool, names the device tool that gave no answer, for placement and for the wait's retry. A command with no dev server refuses NO_DEV_SERVER before it reads a binding; an unreadable EAS binding refuses NO_BOUND_DEVICE. AGENT_CLI_NO_DEVICE=1 skips only this machine's bindings, so an EAS session still scopes the run. runtime:reload --json names the scope under scope: platform, how it was chosen, whether it is bound, and the device's backend, id and name.

Red tests: targetPlatform-test "matches %s to the attached Android device adb names model:Pixel_9"; e2e runtime-bound-selection-test "eval with android-cloud, flag none, reads androidSession"; targetSelection-test "classifyTargets on a bound phone whose model adb spells differently". Also: e2e "runtime:tree refuses with NO_APP_CONNECTED and does not name the session as read".

Live check (adb, on an API 29 emulator whose Build.MODEL is Android SDK built for arm64): adb devices -l printed model:Android_SDK_built_for_arm64, and the match accepted the React Native name Android SDK built for arm64 - 10 - API 29. adb reverse --list printed host-14 tcp:8197 tcp:8197; the parser read tcp:8197 / tcp:8197. At the stack top, runtime:reload --android read the bound emulator by that model, with an EAS Android app on the same dev server skipped, on 3 of 3 runs.

Watch: no physical phone was checked.

Not in this PR: one device type for SelectedDevice and NavigateDevice; one EmptyScopeReason model for the refusal texts.

…bound to it, with or without a platform flag (llp/0035 §Readers)

SelectedDevice is the device a run reads. targetSelection.bound says that
it came from this worktree's binding. The shared resolver picks the scope
for runtime reads and smoke: this worktree's local binding file on the
run's platform while its lease is live, else the one live cloud binding,
else the flags. No inspection decides the scope. A shut-down bound
simulator has no app, so a read refuses and names it, and smoke boots it.
Only an own binding file that cannot be read refuses, with NO_BOUND_DEVICE.

A local simulator scope reads only the app with the simulator's name. A
local Android scope reads the app whose device name carries the bound
serial's model. The target's model and adb's model:<name> are compared in
one spelling, every character that is not a letter or digit as _, so a
"Pixel 9" app is on model:Pixel_9. When another attached device has that
model, the run asks adb reverse --list once on each of them, and reads
only when the bound serial alone reverses this dev server's port.
Otherwise it refuses and names the forward to remove.

An EAS Simulator Android scope skips an app on an attached device of its
model, as an iOS scope skips an app on a booted simulator. Only the tools
of the scope's platform must answer: an Android session reads its app
when simctl failed, and a host with no adb has no attached device. The
inventory keeps attached Android devices once, with their serials.

A read beside a shut-down bound simulator and a live session of this
worktree reads nothing, and the refusal says that only a command that
takes --eas reaches the session. The preflight prints the scope on
stderr. The reload report names the scope and the bound-device source of
its bundle platform.

The per-device rows and their tests are in llp/0005 §Which app a run
reads; the rung order, refusals and known limits are in llp/0035
§Readers.

Bound-device rows that the bound-selection e2e table already pins go. New e2e rows: two emulators
of one model that neither reverses the port, a bound emulator that is not attached, a cloud Android
session beside an arm64 emulator, smoke on a bound simulator whose app appears late, and the
refusal text when a cloud scope excludes another worktree's local app.

…onnection (#202)

**Every runtime command acts on the device bound to this worktree, and
nothing else attached to the same dev server, and says which device it
acted on.**

This PR gives every runtime command one decision about which apps a run
reads, so each layer above changes one place.

Stack: #202 → #203 → #204 → #206 → #217 → #218 → #207 → #200 (this is
1/8).

## Problem

On main, each runtime caller (reads, waits, the bundle check, smoke)
builds its own scope from the flags, and the device facts from simctl
and adb are mixed with decisions. smoke also keeps a failed device
lookup for the rest of the run, so a later phase cannot recover.

## Fix

`TargetSelection` is the run's scope, `DeviceInventory` holds the device
tools' facts, and one resolver classifies the targets.
`RuntimeConnection` carries the classified targets, and every reader,
wait and deferred command reads `classifiedTargets.read`. An attachment
wait keeps the facts for an unchanged list and reads them again, within
its budget, for a changed list. smoke keeps a successful device choice
until a boot or a session start replaces it, and does not keep a failed
lookup. The rules are in llp/0005 §Which app a run reads.

Red test: smoke targetSelection-test "asks the device tools once for a
list that does not change" (4 simctl calls before the fix, 1 after).
Also: "retries a failed device lookup, shares concurrent discovery, and
retains the successful choice".

Live check: run at the stack top only, not at this layer. The local iOS
simulator runs (#207, #218) and the EAS session runs (#203, #200) go
through this layer's scope, classifier and inventory refresh. None of
them counted device-tool calls or forced a failed lookup, so this
layer's claim rests on its red tests.

Watch: an unscoped wait now asks the device tools once for each changed
list that holds an unplaced target.

…ps on local devices (#203)

**Every runtime command acts on the device bound to this worktree, and
nothing else attached to the same dev server, and says which device it
acted on.**

This PR makes an EAS Simulator scope read the session's app and skip the
apps that local devices run.

Stack: #202 → #203 → #204 → #206 → #217 → #218 → #207 → #200 (this is
2/8).

## Problem

The app on an EAS Simulator iOS session registers under the cloud
simulator's model name, for example `iPhone 17`. No local tool reports
that name, so nothing placed the target (DF3, N2-06, N2-09).
`runtime:tree --ios` refused with "No app connected", and smoke reported
`app` unknown after 192 s.

## Fix

On an EAS Simulator scope for iOS, or with no platform flag, a target
that a local device tool names is skipped. The one target that nothing
places is the session's app. While the scope's device tools give no
answer, the targets stay undetermined. `--eas` alone is a cloud scope.
An attachment wait reads the facts again for a changed list. It asks a
tool that gave no answer again at most once a second, and its first read
counts as the first ask.

Red tests: runtime targetSelection-test "holds every unclaimed target
while the local simulators are unknown"; smoke targetSelection-test
"asks a failing simctl again at most once a second while the wait
polls"; preflight-test "should refuse two apps nothing places, and say
how to name the session's platform"; e2e cloud-simulator-test "reloads
the session's app, not the app on a booted local simulator" and "reads
neither unclaimed app with no platform".

Live check: at the stack top, on an EAS iOS session (Expo Go, v2 tunnel)
with a local simulator app on the same dev server: `runtime:reload
--eas` skipped the local app as `other-device` and proved 2 of 2 reloads
by `debugger-context-replaced`; `runtime:reload --ios` skipped the cloud
app and proved 3 of 3 the same way. The `live-cloud` suite passed 17 of
17 at the stack top.

Watch: a session whose model name equals a booted local simulator's name
is skipped as a local app.

**Every runtime command acts on the device bound to this worktree, and
nothing else attached to the same dev server, and says which device it
acted on.**

This PR makes runtime reads and smoke skip an app on a simulator that
another worktree bound.

Stack: #202 → #203 → #204 → #206 → #217 → #218 → #207 → #200 (this is
3/8).

## Problem

A booted simulator that another worktree bound loads its JavaScript from
`127.0.0.1:8081`. When this worktree's dev server takes port 8081, that
app connects to it, and runtime reads read it as this worktree's app
(DF22–DF24, root cause DF29). In worktree `mapfilter`, bound to an
Android EAS session, `runtime:tree --json` returned `bundle.platform:
"ios"`. It read worktree `legend`'s simulator, with old JavaScript.

## Fix

A target is another worktree's app when every booted simulator with its
device name has a udid that only other worktrees bind with a live lease.
When the simulator list cannot be read, a target whose name only other
worktrees' bindings hold is skipped. Runtime reads, the debugger client
and smoke skip that app, with or without a platform flag, and name the
device and the worktree on stderr. `runtime:reload` lists it in
`skippedApps` and does not check its platform's bundle. A released or
expired binding does not count. smoke names the skipped apps once per
run, in its report and on stderr. A runtime read whose list empties
after the preflight refuses like the preflight: `NO_APP_CONNECTED`, exit
22. An `--android` run does not ask `simctl` because another worktree
holds an iOS lease. The no-app refusals live in `scopeRefusal.ts`, so
the debugger client refuses the same way without importing the
preflight.

Red test: targetSelection-test "skips a target with a foreign binding's
name when the simulator list could not be read". Also: e2e
runtime-target-selection-test "runtime:eval skips a renamed foreign
simulator and names its worktree".

Live check: run at the stack top only, not at this layer. The local iOS
simulator and EAS session runs (#207, #203) go through this layer's
binding lookup, but no app from another worktree was attached, so this
layer's claim rests on its red tests.

Watch: at this layer, a broadcast reload still reaches the skipped app.
#207 stops that.

Not in this PR: one `EmptyScopeReason` model for the refusal texts.

…217)

**Every runtime command acts on the device bound to this worktree, and
nothing else attached to the same dev server, and says which device it
acted on.**

This PR moves the reload broadcast into its own module, so the change in
#207 to what a reload reaches reads as a behavior diff.

Stack: #202 → #203 → #204 → #206 → #217 → #218 → #207 → #200 (this is
5/8).

## Problem

The command-socket rung (the dev server's reload broadcast and the
peer-churn wait after it) is inside `src/runtime/reload/reloadAsync.ts`.
That file also holds the reload policy, the evidence wait and the
relaunch. #207 changes this rung. A move inside the same diff would hide
that change.

## Fix

A pure move, with no change in behavior. `reloadOverDevServerAsync`, the
`CommandSocketChurn` type, `PEER_CHURN_TIMEOUT_MS`,
`PEER_POLL_INTERVAL_MS` and the private `waitForPeerChurnAsync` move to
the new `src/runtime/reload/rungOne.ts`. The two constants are exported
because `reloadAsync.ts` still reads them. `reloadAsync.ts`,
`smoke/smokeAsync.ts` and `reloadAsync-test.ts` import them from
`rungOne.ts`. The `reloadAsync.ts` code-line cap goes down to 922.

Red test: none, because the move changes no behavior. The unit suite
passes with only import changes.

Live check: run at the stack top only. This layer moves code and changes
no behavior. At the top, rung 1 broadcast on a local iOS simulator and
was proved by `message-socket-peers` on 3 of 3 reloads.

Watch: `reloadAsync.ts` and `rungOne.ts` share the two churn constants
until the next split.

Not in this PR: the split of `reloadAsync.ts` into evidence, relaunch
and report modules. #207 starts it with `evidence.ts`.

…ext (#218)

**Every runtime command acts on the device bound to this worktree, and
nothing else attached to the same dev server, and says which device it
acted on.**

This PR gives #207 a proof, per debugger target, that a reload replaced
that app's JavaScript context.

Stack: #202 → #203 → #204 → #206 → #217 → #218 → #207 → #200 (this is
6/8).

## Problem

A `Page.reload` keeps the target's page id, so a fresh target cannot
prove it. On main, nothing proves that one target's context was
replaced. An acknowledged `Page.reload` does not show that the app
reloaded.

## Fix

`jsContextReplacedAsync` sets a global with a per-check name, takes the
action, and reads the global on the same target id until it is gone. One
debugger session owns the marker, the action, the reads and the cleanup.
A context that cannot keep the marker is unmarkable, and the action is
not taken. An action that the app answers with a CDP error is thrown. An
action whose answer is lost may have run, so the marker is read anyway.
Each phase has its own bound, and an absolute deadline bounds the whole
proof. The open handshake counts against a request's budget, and a
request that times out names the whole budget the caller gave. The phase
table is in llp/0005 §What proves a reload.

Red tests: contextReplaced-test "does not mistake another concurrent
check for a replaced context"; "the proof of a Page.reload" rows "reads
the marker when the socket drops before Page.reload answers" and "does
not prove a reload whose answer was lost and whose context stayed";
cdpClient-test "should name the caller's budget when the socket opened
late".

Live check: at the stack top, on an SDK 58.0.21 development build on a
local iOS 27.0 simulator, with a second app on another simulator so that
the run skips one app: `runtime:reload --ios --json` reported
`verifiedBy: debugger-context-replaced` (`outcome: context-replaced`) on
4 of 4 reloads, exit 0. On an EAS iOS session (Expo Go, v2 tunnel) with
a local simulator app on the same dev server: `runtime:reload --eas`
skipped the local app as `other-device` and proved 2 of 2 reloads by
`debugger-context-replaced`; `runtime:reload --ios` skipped the cloud
app and proved 3 of 3 the same way. On Android at the stack top, with
Expo Go on a local API 29 emulator and on an EAS Android session on one
dev server: `runtime:reload --android` skipped the cloud app and proved
3 of 3 by `debugger-context-replaced`; `runtime:reload --android --eas`
skipped the local app and proved 3 of 3 the same way.

Watch: on Android the proof was seen with Expo Go only, not yet with a
development build.

"Reloaded yes · via the dev server's client command socket … 2
client(s)". The broadcast also reloaded the skipped app.

## Fix

Rung 1 is decided on one target list read after the bundle gate. While
the scope skips an app, rung 1 sends no broadcast. It sends CDP
`Page.reload` to each own target and proves each with the context
marker, under one shared deadline. When nothing is skipped, rung 1 stays
the broadcast, and the attempt says when it also reached an app outside
the scope. Peer churn beside an app outside the scope makes the attempt
`ok: false, delivered: true`: the reload then needs a fresh own target
or a bundle. Nothing of an app outside the scope proves the reload. The
failure text says whether nothing was watched, the churn was discounted,
or the watched observations did not happen. When no own app could keep
the marker, it says no `Page.reload` was sent. It names `--eas` and the
tunnel only on a cloud run. `Page.reload` has 8 s to prove itself, and
the first proof stops the other checks (`stopped`). A `Page.reload`
whose answer was lost is not delivered. When the read before rung 1
fails, the run keeps its first placement and sends nothing (mechanism
`none`). After a relaunch that nothing can prove, local or cloud, the
run exits 22 at once instead of waiting out `--timeout`. CI runs the
reload cases that need a local simulator on the macOS job.

Red tests: rungOne-test "a broadcast beside an app nothing places: no
bundle proves it"; e2e runtime-target-selection-test "sends Page.reload
to its own app only, and a page of the skipped app proves nothing
($pageReload)", "sends no Page.reload when its own app cannot keep the
marker" and "runtime:reload does not take another platform's churn as
its proof".

Live check (before the 8 s window and the relaunch exit; not rerun
since): at the stack top, on an SDK 58 development build on a local iOS
simulator. With a second app on another simulator, the run skipped it as
`other-device`, sent `Page.reload` to its own app only, and proved 4 of
4 reloads by `debugger-context-replaced`. With one app, it broadcast and
proved 3 of 3 by `message-socket-peers`. On an EAS iOS session (Expo Go,
v2 tunnel) with a local simulator app on the same dev server:
`runtime:reload --eas` skipped the local app as `other-device` and
proved 2 of 2 reloads by `debugger-context-replaced`; `runtime:reload
--ios` skipped the cloud app and proved 3 of 3 the same way.

Watch: when rung 1 broadcasts, an app that attaches after the last
target list also gets the broadcast.

**Every runtime command acts on the device bound to this worktree, and
nothing else attached to the same dev server, and says which device it
acted on.**

This PR makes `navigate` decide "attached" from the device it opens.

Stack: #202 → #203 → #204 → #206 → #217 → #218 → #207 → #200 (this is
8/8).

## Problem

`navigate` counted the attached apps of every platform. N3-25 (also
DF22): after `dev --android --eas`, with only a local `iPhone 17 Pro`
app on port 8081, `navigate "/street/…"` with no flag counted the iOS
app as attached. It skipped the launcher, opened only the route link,
and exited 22 after 120 s. On Android, the stuck-app recovery could also
stop an app that another device ran on the same dev server.

## Fix

`navigate` validates the route, resolves the device, and then reads the
attached apps of that device's scope to decide the app kind, the route
URL and the launcher. One reader serves the launcher wait and the route
wait. It reads the device facts again only for a changed list, within
the budget of the wait that polls. So a cloud app that attaches after
the accepted Expo Go dialog counts. When an Android twin of the bound
device is attached, `navigate` reads `adb reverse` before the launcher
decision and again after this run's own `adb reverse`. When nothing
attached on Android, the recovery stops `--app-id`, else the app
config's app, else Expo Go. smoke hands its device to the route open, so
the open and the waits are about one device. `--print-url` reads the
scope as `navigate` does, `adb reverse` included, once the dev server
lists an app. The recovery stops Expo Go when this run opened it, and
says the app was stopped only when `pidof` saw it running.

The first commit is a pure move of route URL resolution to
`src/navigate/routeResolution.ts`. The second commit holds the behavior.

Red tests: navigate-target-selection-test "no flag, bound Android
emulator, only an iOS app and another model's Android app attached";
navigateAsync-test "asks adb for the device list once while the attach
wait polls an unchanged list"; e2e cloud-simulator-test "counts the app
that attaches after the dialog is accepted";
navigate-target-selection-test adds three Android twin rows, one of them
"no flag, bound Android emulator beside a twin, neither reverses the
port before this run".

Live check: the `live-cloud` iOS suite passed 17 of 17 at the stack top
on an EAS session: `navigate / --eas` exit 0, attached after 3 ms. Plain
main gives the same results.

Watch: after a wait's budget ends, its later polls keep the last device
facts.
