agent 551faf8450 refactor(is): retire the direct-iOS selector shortcut
thymikee's ruling (option b). `is` declares `device-runtime`, so its request path
must reach the device only through the operations R37 declares. It did not: a
simple iOS `id=`/`label=` target was answered by a direct XCUITest querySelector
without any capture, ordered after admission but not executing through the seam.

This is not retired because it was wrong. `wait` hypothesized that the degenerate
one-node evaluation mis-answers `is visible` for off-viewport nodes, traced it
through the code convincingly, then tested it on device and it did not reproduce
— XCUITest's own query is conservative about visibility, so the degenerate
evaluation never gets the chance. It is retired because it was an undeclared,
unmeasured bypass that made R37's singularExecution claim false: the same class
of untruth as the sentinel retirement names fixed in the previous commit.

Declaring querySelector as a real operation instead was rejected for a concrete
reason: offscreen-target-probe.ts consumes queryDirectIosSelector with a plain
session and cannot take a bound operation, so declaring it now would ship it
twice until Wave 5 moves the probe — the deferred-duplication shape that got
get's read deferral overruled. It returns as a declared, fact-admitted,
section 9-measured operation in the unit that also moves the probe.

Retired: dispatchDirectIosSelectorIs, its call site, buildDirectIosIsResult, and
resolveDirectIosSelectorQuery — each had exactly one caller, all on this path —
plus the ResolvedDirectIosSelectorQuery type they orphaned and two imports.
queryDirectIosSelector itself stays: the offscreen probe still consumes it and it
remains single-copy.

Latency cost, stated plainly and not softened: a held predicate on a simple iOS
selector goes from ~0.14s with no capture to ~0.25s with one, measured as the
median of 9 warm runs on iPhone 17. There is no fallback and no fast path.

R37's comment finally describes the code: "every predicate answers from the
resolved tree" was written while the shortcut existed. Its scope is now stated
too, so it is not read as absolute — the Android foreground-blocker diagnostic
still reaches adb on the failure path, where it cannot produce or change a
verdict; that edge is pre-existing, co-owned with wait, and recorded as Wave 6
denominator work with R22's appState as its declared replacement.

Seven tests lost their subject. Those whose only content was the shortcut's own
mechanics are deleted; the outcome-level ones are retargeted and keep asserting
what survives.

agent 96d1e72e18 test(is): pin the exit-code guarantee independently of what answers the predicate
Prep for the Blocker 1 retirement, which deletes `buildDirectIosIsResult` — the
function the #557 reversal fixed. The reversal's guarantee must not evaporate
with it, so it gets a case that does not know how the daemon decided.

`is` is documented to "exit non-zero on failure". The reversal proved that at
the JSON envelope; nothing pinned it at the CLI boundary, which is where the
defect was actually visible (`Passed: is text`, exit 0). This asserts the CLI
contract directly: a `predicate_failed` response exits 1 and never renders as
passed.

It survives the retirement untouched, because it asserts the outcome rather than
the path. Planted red with the exact pre-#1739 envelope the shortcut produced
(`{ok: true, data: {pass: false}}`): `exitSpy.calls` is `[]` — no exit call at
all — so the case fails, which is the regression it exists to catch.

Unpushed on purpose: the restack will carry it into the retirement cycle.

agent e61f90974f fix(is): a failing iOS assertion fails instead of exiting zero
Reverses part of #557, on thymikee's explicit instruction.

`is` is an assertion: the docs state it "exits non-zero on failure". The
direct-iOS fast path broke that contract — it reported a failed predicate as a
completed command, so on device

    $ agent-device is text id=… "Wrong Expected Text"
    Passed: is text          (exit 0)

because `{ok: true, pass: false}` reaches `isCliOutput`, which renders
"Passed: is <predicate>" without reading `pass`. A failing assertion reported as
success lets a replay run on past a broken state. Now:

    Error (COMMAND_FAILED): is text failed for selector id=…:
      expected="Wrong Expected Text" actual="Apple Account, …"   (exit 1)

The renderer needed no patch: a negative can no longer produce a success
envelope, so it is correct by construction.

Direction chosen deliberately. Making the two paths agree could have gone either
way, and "an agent asked a question and got an answer" is a real argument for the
other one. This follows the DOCUMENTED contract rather than merely the incumbent
behaviour, and the alternative is a far larger change: a zero-exit `is` would
alter every platform and path, break scripts that rely on it failing the shell,
and needs its own PR, docs, and probably a major version. It is also already how
`is hidden` and `is exists` behave end to end.

PASSING assertion, and that arm still answers with zero captures (pinned). Only
the negative falls through — what #557's own summary asked for, "preserving
snapshot fallback for misses", refusing fallback only for hard failures like
ambiguity. The fall-through was #557's own design, never armed: the `| null`
return and the caller's `if (!payload) return null;` guard were unreachable.
This makes that dead guard live.

Measured on iPhone 17 (median of 9, warm daemon): predicate holds 0.14s / 0
snapshots, unchanged; predicate fails 0.25s / 1 snapshot. ~+0.11s on failing
assertions only.

Correctness gain beyond the envelope: the fast path evaluates a ONE-NODE tree, so
`visible` cannot see the ancestor geometry a list row inherits and its negative
can be wrong. Falling through re-asks the real tree and can turn a spurious
negative into a pass.

The #557 pin moved with its reasoning at the pin site.

agent c6f7a7553e refactor: migrate is to the request-bound device runtime
`is` declares the shared selector capture use, admits once from exact owner
facts, refuses before binding, and binds exactly once. Its capability bucket,
the static HarmonyOS/Web command sets that augmented it, and
`requireCommandSupported` admission for `is` are gone; `'is'` leaves the
`createSelectorRuntime` capability union.

Admission now runs BEFORE the direct-iOS selector fast path. ADR 0019 requires
resolve -> admit -> bind before anything in a `device-runtime` command's request
path reaches the device, so that query becomes a fast path *within* an admitted
request rather than a way around exact-owner facts. The rule is documented once,
on `createBoundSelectorRuntime`, replacing the two duplicated call-site comments
`get` and `is` were each carrying.

Declared behaviour change: `is` takes the active-app plan split, so the facts
decide per family. On iOS `appBundleId` is the XCUITest attach target — with no
tracked app the runner's own process comes to the foreground, displaces the app
under test, and the capture then answers confidently about the runner's own
blank screen. An iOS `is` on a session with no tracked app is now a typed
SESSION_NOT_FOUND refusal carrying the `open` hint. Refusing beats
displacing-and-lying. Android captures the real launcher in that state and is
unchanged, which is what the platform facts already encoded.

The two Apple watchOS cells move from capability-admitted-then-runner-failure to
a typed unavailable refusal, the same classification snapshot, diff, and get
already landed.

R37 is the new parametrized cutover row. `find` keeps `createSelectorRuntime`
and its `requireCommandSupported` call, so `captureData` stays optional and
`captureSnapshotWithInteractor` stays: this unit is not the last selector unit.

agent aa12c9ff41 refactor(get): retire the direct-iOS selector shortcut
`get` declares device-runtime, so its request path must reach the platform only
through operations R36 declares. `dispatchDirectIosSelectorGet` reached
`runAppleRunnerCommand` through a path the row declares no operation for;
admitting before a bypass is not executing through the seam, so the bypass is
removed rather than ordered after admission. Every target shape — including the
simple iOS `id=` selector — now resolves through the bound capture.

`queryDirectIosSelector` itself stays: `offscreen-target-probe.ts` still
consumes it and it remains single-copy. `dispatchDirectIosSelectorIs` belongs to
`is` (#1883). Two get-only helpers (`readDirectIosGetSelector`,
`buildDirectIosGetResult`) became unreachable and are deleted with the caller.

Declaring `querySelector` as a fact-admitted preferred operation was rejected on
duplication, not correctness: the offscreen probe takes a plain session and
cannot consume a bound operation, so it would ship the query twice until Wave 5
moves the probe — the deferred-duplication shape this PR was already overruled
for on the `read` alias. It returns as a declared, §9-measured operation in a
later unit that also moves the probe.

Cost, stated plainly: `get text id=…` loses its tree-capture skip on iOS. No
fallback was added and the latency is not recovered elsewhere. R36's
singularExecution claim is now what the code does rather than aspirational.

agent 52a1c9d186 refactor(daemon): apply the seam addendum after #1876 was re-scoped
Two edits, per find's ADDENDUM.md:

1. `includeRects` returns to `buildRuntimeCaptureInput`. It was removed from
   #1876 as unconsumed; the selector capture path is genuinely its first
   consumer (a Web rect capture requests bounds explicitly), so it lands here
   under the same rule that moved the seam. `snapshot`/`diff` pass nothing.

2. The per-capture `signal` is dropped, not restored. `CaptureSnapshotInput`
   has no such field on this stack — it moved to `wait` (#1875) with the
   regression that proves per-poll abort and quiescence. `get` captures once
   per resolution and never polls, so nothing here needs it. The seam test and
   fixture coverage for it moves with the contract rather than being kept
   against a field that no longer exists.

agent baba1ea553 refactor: retire the read dispatch alias across both selector consumers
Read-only `find` now constructs a BOUND selector backend, so `get text` and
`find <q> get text` execute the same bound `readTextAtPoint` instead of one
binding it and the other dispatching the legacy `read`. This moves find's READ
LEG only: find's descriptor stays LEGACY_PLATFORM_EXECUTION and it claims no
cutover row.

With no consumer left, the whole chain goes: the `read` registry entry and its
`dispatch: {}` projection, `DISPATCH_HANDLERS.read`, `handleReadCommand`,
`interaction-read-legacy-dispatch.ts`, and the duplicate platform reader
branches it carried. `read` was the only `dispatch-alias` descriptor, so that
catalog group goes too.

Deleting the registry entry drops 'read' from DescriptorDispatchCommandName,
which makes a surviving DISPATCH_HANDLERS.read a compile error rather than
something R36 has to police. R36 now claims the retirement it can prove.

`find.test.ts` is over the size tripwire, so its handler invocation is
extracted to find-handler-fixture.ts and the pin lowered 1237 -> 1221.

agent 8abcb5d053 feat(daemon): land the selector capture seam with get as its first consumer
Takes ownership of the request-bound selector capture seam from #1876, which
cannot ship standalone: with find's cutover deferred it had no consuming
command (ADR 0019 §10) and was not dead-code clean (check:production-exports
19 -> 20). `get` is its first consumer, so it lands here.

Adopts find's handoff as given. The one shape change, approved by the
coordinator: the selector family gets its own capture uses carrying a PREFERRED
`readTextAtPoint`, declared ALONGSIDE the snapshot uses so `snapshot`/`diff`
keep binding exactly what they bind today. The read is surfaced through the
existing arms of `bindSnapshotCaptureRuntime`, reusing the same
selectActiveAppSnapshot / selectSnapshotWithoutActiveApp selectors — no second
plan-to-operation dispatch.

`get` now runs through `createBoundSelectorRuntime`; `resolveBoundGetRuntime`
and its test are deleted as superseded, and `'get'` leaves the
`createSelectorRuntime` capability union.

The legacy read adapter survives for `find <q> get text` and is selected by
which command constructed the runtime — never by failure, family, environment,
or flag — so `get` cannot reach it. It retires in find's cutover, where the
last consumer moves.

agent faca04879d fix(get): admit before the direct-iOS fast path; close the element-read outcome
Review blockers on #1877.

1. `dispatchGetViaRuntime` could complete the direct-iOS selector query before
   `resolveBoundGetRuntime`. Once `get` declares `device-runtime`, ADR 0019
   requires resolve -> admit -> bind before anything in the request path
   operates, so admission now runs first for every target shape and the fast
   path is a fast path *within* an admitted request. Regression: an eligible
   direct selector cannot operate when facts refuse admission.

2. `readTextAtPoint` returned `Promise<string>` and `readTextForNode` caught
   any throw and fell back, assigning a typed diagnostic after an untyped
   failure. It now returns a closed `ElementTextReadOutcome`; fallback happens
   only for the contract's classified reasons; unexpected errors propagate.
   The reason union is derived from its runtime list so the two cannot drift,
   and an unhandled reason is a compile error at the consumer.

This retires the generic catch the start record promised.

agent 066575cd2b refactor: migrate get to the request-bound device runtime
`get` declares `elementReadRuntimeUse` (required `captureSnapshot`, preferred
`readTextAtPoint`), admits once from exact owner facts, refuses before binding,
and binds exactly once. Its capability bucket, the static HarmonyOS/Web command
sets that augmented it, and `requireCommandSupported` admission for `get` are
gone; `'get'` leaves the `createSelectorRuntime` capability union.

The neutral `readTextAtPoint` operation replaces the branch-per-family legacy
`read` dispatch on the `get` path. Every local family and both providers now
classify it exhaustively — Web, HarmonyOS, Vega and every provider row report it
unavailable, which is behaviour-preserving because the legacy dispatch had no arm
for them and threw on every call before falling back.

R36 is the new parametrized cutover row.

Michał Pierzchała d29dc22861 fix(android): warn when a permission revoke kills the session app (#1856)
* fix(android): warn when a permission revoke kills the session app

settings permission deny|reset maps to pm revoke, and Android kills the
app's process whenever a runtime permission it currently holds is revoked,
so a grant -> deny/reset sequence silently left the session on the launcher
and the next selector failed with no hint. The revoke path now reads the
prior grant state from dumpsys package first and, when it was granted,
returns wasGranted: true plus a warning naming open <app> --relaunch; the
settings CLI output renders response warnings, and commands.md documents
the behavior next to the pm revoke mapping.

Closes #1796

* fix(android): state the revoke-kill consequence conditionally

Review finding: the warning asserted the app had been killed, inferred only
from the prior grant state. dumpsys reports granted=true for any user
profile while pm revoke acts on the current one, and the app need not have
been running, so the claim could be false. State the platform rule and make
the consequence conditional; the relaunch guidance is unchanged.

* fix(android): model the prior grant state as granted/not_granted/unknown

A failed or unparseable dumpsys read as "nothing granted", so the response
asserted the app was untouched when the state was simply unknown, and the
grant scan matched every granted=true line — install permissions and other
users' blocks included — so another profile's grant could claim a kill that
never happened. Both directions of the same defect.

The read now resolves the acting user (am get-current-user) and walks the
dump's nesting (Packages: > User <id>: > runtime permissions:), and reports
priorGrantState: granted | not_granted | unknown. unknown carries the same
relaunch guidance without claiming what the state was; only not_granted is
silent.

* fix(android): address the foreground user in every permission mutation

The tri-state read scoped state to am get-current-user, but the mutations
ran bare pm grant/revoke and clear-permission-flags.
PackageManagerShellCommand defaults those to UserHandle.USER_SYSTEM, so on
a device whose foreground user is nonzero the command read one user's state
and edited user 0 — leaving the running app's permission untouched while
reporting on a user it did not change.

Proven on a Pixel 7 / API 36 emulator with the foreground user switched to
10: a bare pm revoke flipped User 0 to granted=false and left User 10
granted=true.

The foreground user is now resolved once and passed as --user to pm
grant/revoke, pm clear-permission-flags, and appops set, and the state read
takes that same id. When it cannot be resolved the mutation keeps the
platform default and the state is reported unknown rather than guessed.

* test(android): pin the user-scoped permission argv in the provider scenario

The scripted ADB provider answered only the unscoped pm grant/revoke form,
and the Settings contract asserted the unscoped transcript entry, so the
provider lane could not see which user a permission mutation addressed.

* test(android): extract the settings contract out of the lifecycle monolith

The user-scoped argv assertions pushed android-lifecycle.test.ts past its
size ratchet, whose instruction is to extract rather than grow a file over
the tripwire. assertAndroidSettingsContract moves to a sibling module and
the pin drops 1597 -> 1559.

* refactor(android): shrink the permission path to one concept per file

Size/design pass on the #1796 change:
- settings.ts was 505 lines (past the 500 extract-before-adding tripwire);
  the permission family moves to settings-permission.ts and the dispatcher
  drops to 265.
- permission-grant-state.ts loses topLevelSection (a nestedBlock with an
  indent-0 header), its single-use line reader, and androidPriorGrantState
  (one map lookup at its only production call site).
- the grants map narrows to 'granted' | 'not_granted': unknown was never a
  value, absence is what carries it, so the tests read the map directly.
- the permission tests move to settings-permission.test.ts and consolidate
  into argv/tri-state/photos/rejection tables; the parser tests fold seven
  cases into two.

Every red-proof re-run after the consolidation: dropping --user reds 7
argv/photos cases, and the pre-fix state model reds 13 across both files.

* fix(android): refuse permission mutations that cannot name their user

The fallback issued bare pm/appops commands when am get-current-user did
not answer, which is the #1796 defect itself: those default to
UserHandle.USER_SYSTEM, so a session running as user 10 had user 0 edited
while the response reported only priorGrantState: unknown. It was also a
fallback added without approval, and the docs' claim that every mutation
names its user was false on that path.

Resolving the acting user is now a prerequisite: setAndroidSetting
permission fails with COMMAND_FAILED and a recovery hint, issuing no pm,
appops or clear-permission-flags call at all. The test that locked the
fallback in is replaced by one asserting the empty mutation call list for
grant, deny and reset.

Michał Pierzchała 735ab7672a refactor(daemon): one capture-input builder and one admit-then-bind step (#1876)
Behaviour-neutral. No descriptor changes platform execution, the cutover table
is untouched, and no contract surface is added.

- buildRuntimeCaptureInput moves to its own module so every request-bound
  capture consumer builds CaptureSnapshotInput one way.
- The admit-then-bind sequence in the snapshot/diff resolver becomes one named
  step, ready for the selector units' second caller.
- handlers/find.ts splits into focused target-capture and match-resolution
  concepts (600 -> 346 lines); behaviour unchanged.

Michał Pierzchała 67ce19b50c fix(daemon,kernel): device-selection safety — identity conflicts and ambiguity fail instead of retargeting (#1880)
* fix(daemon): session-lock identity conflicts fail instead of changing device identity

`--session-lock strip` resolved every conflict by deleting the offending selector, including
--udid/--serial/--device. The command then ran against the BOUND session's device rather than the
one the caller named, and the error hint that produced this state actively recommended strip. A
wrong-device tap that reports success is worse than any loud failure, so:

- a conflict on a device IDENTITY selector now fails under both reject and strip; strip keeps
  resolving platform/scope selectors (--platform, --target, --ios-simulator-device-set,
  --android-device-allowlist), which is what it exists for;
- the structured error carries both sides (requestedDevice, boundDevice) so a caller can choose a
  recovery without parsing prose;
- the fresh-session hint offers the two real recoveries — close the bound session if the requested
  device is intended, drop the selector if the bound device is — and never mentions strip for an
  identity conflict. The existing bound-session hint already stated both and is unchanged.

Admission-layer only: this is device/session resolution policy, evaluated before any interaction
dispatch path is selected, so no ADR 0011 guarantee cells move.

One table pins the crossing: fresh vs existing session, matching/conflicting/absent identity,
reject vs strip, binding vs inventory command, Android serial / Android udid / Apple udid, with the
exact error details and hint asserted. 7 of its 13 rows are red against the previous policy.

* fix(kernel): validate platform-specific device flags before resolution

`--udid` enters Apple resolution unconditionally, so `--platform android --udid emulator-5580`
answered "No Apple device with UDID emulator-5580" — an answer about a platform the request had
explicitly excluded, which reads as a missing device rather than a mistyped flag. Both directions
now fail as INVALID_ARGS naming the correct flag (--serial for Android/HarmonyOS, --udid for Apple).

Requests that name no platform keep the existing DEVICE_NOT_FOUND behavior, since nothing
contradicts the selector there.

* fix(kernel): refuse ambiguous singular device resolution instead of picking one

resolveDevice answers with exactly one device, so every caller of it needs one concrete device. When
the request carried no identity and several candidates were equally preferred, it returned the first
by discovery order (or alphabetically for Apple) — a successful response describing a device the
caller never selected. That is worse than any loud failure, and reads are not safer than writes: a
snapshot of the wrong emulator is a wrong answer that looks right.

Ambiguity is now a refusal at the resolver boundary, not a command-kind allowlist:

- established preference tiers are preserved (virtual over physical, the Apple kind/target rank,
  then booted over offline); only what survives them equally is ambiguous, since the comparator's
  remaining tie-breaks are name and discovery order, which encode nothing about intent;
- one booted emulator beside offline candidates still resolves, as do explicit --device/--udid/
  --serial and any command inside an existing session, whose identity is already fixed;
- multi-device commands ("devices") never enter singular resolution;
- the error reuses the declared device-candidate details domain (AMBIGUOUS_MATCH + "devices"), so
  CLI and MCP already render the bounded list, with a hint naming the platform-appropriate selector.

* fix(kernel): drop the mismatched article from the selector-flag hint

"Use --serial X to select a android device by serial" — the platform name is interpolated, so no
article fits every value. Names the flag's platform family instead.

Michał Pierzchała e4c3b420a4 test: refuse foreign-pid signals from unit-test workers (Coverage fork death, #1824) (#1854)
* ci: w3-1824 experiment — trace fork signals and plant pid sentinels in the Coverage job

Temporary instrumentation for #1824. Every vitest fork logs each real
process.kill it sends to a foreign pid (and every kill/pkill it spawns);
the Coverage job parks sentinel processes on the pids the Apple runner
tests fabricate (4141/4242/4343/4444) and reports which of them survive
the run. Reverted before this PR leaves draft.

* test: refuse foreign-pid signals from unit-test workers

A vitest worker may signal only itself and the processes it spawned.
src/__tests__/hermetic-signal-setup.ts records any other process.kill,
answers it with ESRCH (so best-effort kill paths proceed as if the pid
were dead), and fails the sending test by name in afterEach.

The senders this catches today are the Apple runner tests, which
fabricate runner child pids (4242, 4141, 4343, 4444) and mocked the
liveness reads in host-process.ts but not the signal writes:
killRunnerProcessTree delivered real SIGINT/SIGTERM/SIGKILL to those
pids and their process groups — 146 signals per run of
runner-session.test.ts. On the CI runner the sibling vitest forks live
in that pid band, so the Coverage job periodically lost one fork
mid-file with no test attributed (issue #1824, 6 of the last 40 red CI
runs).

The group-signal write moves behind signalProcessGroupBestEffort in
host-process.ts, next to signalPidsBestEffort, so the runner tests mock
the signal seam in the same place they already mock the liveness reads.

* Revert "ci: w3-1824 experiment — trace fork signals and plant pid sentinels in the Coverage job"

This reverts commit a8a020099c.

* test: refuse spawned kill/pkill writes too, and share the guard with the mutation lane

Review of #1854 found three gaps in the first pass:

- The guard intercepted process.kill only, so the spawned half of the same
  function family was unguarded: runner-disposal spawns `pkill -P <pid>` and
  `pkill -f 'xcodebuild.*AgentDeviceRunner.env.session-...'`, and
  request-router-open.test.ts fired that pattern kill twice per suite run. On a
  developer machine with a live Apple runner, `pnpm test` could reach it. The
  setup file now refuses kill/pkill/killall spawns with ENOENT — which the
  best-effort callers already tolerate — and records them the same way; that
  test stubs the Apple tool seam.
- vitest.mutation.config.ts hard-coded its own setupFiles list, so the Stryker
  lane ran without the guard. SETUP_FILES is now exported from vitest.config.ts
  and imported there, next to the SUBPROCESS_STUB_TESTS import that already
  crossed the same boundary.
- 'processes it spawned' meant direct children only; a grandchild started
  through a shell wrapper was refused with advice that did not fit. The docs and
  the failure message now say direct children and name the remedy.

Synchronous spawns are no longer remembered as own pids: spawnSync and
execFileSync have already exited when they return, so keeping their pids would
license a signal to whatever inherits them next.

Refs #1824

* test: end signal authority at child exit, and guard the promisified execFile path

Re-review of #1854 found two holes in the guard itself, both the class it
exists to close:

- An async child's pid stayed authorized for the worker's lifetime after it
  was reaped. A pid is a claim on a process-table slot, and the kernel reissues
  that slot once it is free, so 'I spawned this pid once' licensed a signal to
  whatever holds it now. Authority now ends on exit/close. Cleanup that signals
  a child must gate on isProcessAlive, which is what the existing cleanup paths
  already do.
- wrapSpawner copied execFile's original util.promisify.custom onto the
  wrapper, and promisify() resolves through that symbol instead of calling the
  function — so every promisified caller got an unguarded execFile, bypassing
  both the kill-binary refusal and child tracking. That path is now wrapped too.

hermetic-signal-setup.test.ts covers both, plus the allowed cases they could
regress into: a reaped child's pid is refused, a promisified execFile cannot
smuggle a pkill, a promisified child is still tracked, a live foreign pid is
refused, and signal 0 stays free. Reverting either fix reds three of them.

* test(utils): pin the recovery hints the AppError conversion added

The tightened assertions supplied only code and message, and the helper did
not look at the hint, so deleting either hint constant left every targeted
test green — vacuous for the half of #1792 that ADR 0010 actually cares
about. assertThrowsAppError/assertRejectsAppError now accept a hint,
checked against normalizeError's view so a dropped hint surfaces as the
misleading per-code default rather than passing, and each guard pins its
exact text as a literal (importing the constant would compare it to
itself).

Michał Pierzchała 8c06965d28 fix(daemon): cap events.ndjson with cursor-safe rotation (#1867)
* fix(daemon): cap events.ndjson with cursor-safe rotation

Rotate events.ndjson to events.ndjson.1 once it reaches
AGENT_DEVICE_EVENT_LOG_MAX_BYTES (default 5 MB), keeping one rotated
generation. Cursors stay absolute across rotation through a sidecar
window offset, so a persisted nextCursor still names the same event; a
cursor older than the retained window fails with COMMAND_FAILED and
details.reason EVENT_LOG_CURSOR_EXPIRED instead of returning a wrong
page.

Closes #1788

* fix(daemon): verify the events.ndjson window against the files on disk

Rotation recorded only a dropped-line offset, written after the rename,
so a reader landing in that window mapped every absolute cursor a whole
generation too far (reproduced: 5 of 58 reads returned event 17 for
cursor 9), and a missing rotated file or stale sidecar shifted cursors
permanently and silently.

The sidecar now records each retained generation's first absolute line
index, line count, and first-line digest, and is written before the
rename it describes. The reader identifies each file on disk by digest,
derives its start from the matching record, and checks the recorded line
count and generation contiguity; anything unverifiable raises a typed
EVENT_LOG_WINDOW_UNVERIFIED instead of a guessed offset. A torn snapshot
(rotation landing mid-read from the threadpool) is retried, not
interpreted. A corrupt sidecar fails reads typed and never blocks
appends, and rotation no longer does synchronous whole-file I/O.

Michał Pierzchała f3d5b3d92c refactor(daemon): admit-before-bind as an admitted-plan token; retire the R32 syntax policy (#1841)
* refactor(daemon): admit-before-bind as an identity-keyed admitted-plan token; retire the R32 syntax policy

admitRuntimePlan (was inspectRequiredRuntimeUse) takes the plan and, on
success, mints an AdmittedRuntimePlan: a nominal class instance with nothing
readable on it. Its payload — a frozen copy of the device the facts were read
for, and the plan — lives in a module-private WeakMap keyed by the token's
exact identity, and the only way to read it is unwrapAdmittedRuntimePlan,
which refuses anything not minted here. The snapshot owning interface
(resolveBoundSnapshotCaptureRuntime, #1847) admits through it and its private
binder takes only the token: no bare plan, no separate device, and no
look-alike — a spread lacks the #private member (not assignable), a Proxy
around a real token types as the token but is a different identity (refused
at unwrap), Object.assign/defineProperty throw on the frozen instance, and the
class value is not exported so its constructor is not nameable.

That retires scripts/layering/runtime-command-cutover-snapshot.ts — R32's
per-command AST policy (call-shape recognition of the admission and a text
sniff for a local admission) — and the source-regex test beside the descriptor
tests. The generic row keeps retirement, narrowing, and singular execution;
the manufactured-proof column now also rejects casts to AdmittedRuntimePlan.

Planted reds: token degraded to a plain public shape → 2 unused
@ts-expect-error directives; unwrap reading the token surface via getters →
the Proxy regression fails; getter-based branded literal → the runtime
retarget test fails.

* docs(agents): the ADR 0019 unit checklist teaches the shipped admission API

#1836 documented inspectRequiredRuntimeUse with a forward note pointing here;
this PR makes admitRuntimePlan real, so the row now teaches it plus the
identity-keyed unwrap the binder uses, and points at the shared snapshot/diff
owning interface as the model.

Michał Pierzchała 275a66ea23 test(ratchet): pin snapshot-handler.test.ts at main's 2654 lines (#1860)
#1847 grew the file 2652→2654 and merged minutes before #1843 pinned it at
2652 (measured against the merge-base #1843 had at the time). Both PRs were
green alone and main is red together — the cross-PR growth the equality pin
exists to catch, landing as a catch-up rather than a raise: the history rule
agrees (2654 at the merge-base).

Michał Pierzchała b12a3e3cb3 test: pin test files over 1,000 lines at their exact length so they can only shrink (#1843)
* test: pin test files over 1,000 lines at their exact length so they can only shrink

AGENTS.md has said for a while that past 1,000 lines is architecture debt and
tests are not exempt; nothing enforced it, and the second-largest test file
gained 55 lines in the PR before this one. This is the slow-test ratchet's
shape for a reader's context instead of wall clock: the 26 test files over the
tripwire are pinned at their exact length (R9-style equality pin, #1781 A6);
growth fails, shrink fails until the pin is lowered in the same PR, a file
that drops under the line leaves the list, and a new file may not cross it.
One directory walk per unit run, ~250ms; the pin list emptying deletes it.

* test(ratchet): hold giant test files to their merge-base length so pin edits cannot admit growth

Review (P1): the equality pin compared measured lengths only against the pin
map in the same checkout, so growing a file and raising its pin, or adding a
new >1,000-line file with a pin, stayed green. The gate is now history-backed:
every test file over the tripwire may be no longer than at the merge-base with
origin/main (renames followed; new files may not cross the line), and no pin
may exceed its file's base length — one git cat-file --batch spawn, parsed by
bytes because the sizes are bytes. Both bypasses planted red against real git
on a pinned file and on a fresh 1,001-line file with a pin added.

* test(ratchet): a pin on a file at or under the tripwire is itself a finding

Review: a new pin for an unchanged sub-tripwire file (900 pinned at 900)
passed equality and history and grew the map. Pins now exist only for files
over the tripwire — any other pin is red with 'remove it' — which also
subsumes the old shrink-under-the-line message. Planted red in-file and
against real git (a 186-line test pinned at 186). The android snapshot test
pin bootstraps 1636→1660: main grew that file in #1846 before this gate
exists, and history agrees (1660 at the merge-base).

Michał Pierzchała 294654a3a5 fix(android): resolve snapshot scope once and disclose the API 23 occlusion-scan gap (#1832 C1/C2) (#1846)
* fix(android): resolve snapshot scope once and disclose the API 23 occlusion-scan gap (#1832 C1/C2)

- Android resolves --scope inside its projection only, under the shared scope specification
  (matchesSnapshotScope in @agent-device/contracts/snapshot: first document-order match over
  label/value/identifier, empty on no match). The daemon post-wire scopeSnapshotNodes pass skips
  the android backend, so scope has one owner and one no-match semantics instead of BFS+fallback
  followed by document-order+empty.
- Golden table contracts/fixtures/snapshot-scope-policy.json is asserted against the predicate,
  the Android projection, and the daemon pass; the Swift runner twin (#1797) consumes the same table.
- androidSnapshot.occlusionScanUnavailable discloses helper trees without drawing-order (API 23),
  where the covered-sibling pruner cannot run. Disclosure only; C1 stays open until occlusion moves
  to the daemon annotator.

* fix(android): resolve scope over the presented tree and stop dropping it on interaction captures

Adversarial review findings on the first commit:

- BLOCKER: captureSnapshotData spread `snapshotScope: undefined` over flags, so an interaction
  capture (press/click/fill/longpress/hover --scope, --settle observation) reached the Android
  platform unscoped while buildSnapshotState still saw the scope. The post-wire pass used to rescue
  it; after skipping android it returned the unscoped tree. One effective scope now feeds both.
- Scope resolves over the PRESENTED nodes of the requested projection, not the acquired tree, so an
  acquired match that membership drops no longer empties the snapshot, and Android matches the
  domain iOS's pass uses.
- Slicing after the walk keeps ancestor context (hittable/collection/chrome) above the scope root,
  so scoped -i is a subset of unscoped -i; --depth stays scope-relative.
- Shared findSnapshotScopeRange/reindexSnapshotNodes so the daemon pass and the Android projection
  run one implementation; scope slice extracted to ui-hierarchy-scope.ts (mirrors its test).
- parseUiHierarchy moved to a test fixture module (it had no production caller left).
- Golden rows sharpened (value row no longer matches via label on Android); the Android leg runs
  raw AND regular. CHANGELOG entry; docs wording corrected for iOS/@ref.

* fix(layering): keep the contracts snapshot façade exhaustive over snapshot-scope

* fix(android): scope to the first match whose subtree still has presented content

Review P1 on #1846: with scope resolved strictly over presented nodes, `snapshot -i --scope panel`
answered "no nodes" whenever the matched container was a structural view membership drops — even
though the button inside it was exactly what was asked for — and `--depth 0` then hid a node the
response prints at depth 0.

The scope root is now the first document-order match whose subtree contributes at least one node to
the requested projection, and the result is that subtree's presented nodes re-rooted at depth 0.
Both failure modes die: a decorative match membership drops no longer empties the snapshot, and a
dropped container still scopes to its content. `--depth` under scope filters the depths the
response emits, so a node shown at depth 0 survives `--depth 0`.

Tests: the golden legs stay raw+regular (bare TextViews cannot survive -i, so an -i leg would
measure membership, not scope) with the projection interplay pinned by two dedicated tests on
actionable shapes; the 'not re-scoped after the wire' case now runs a real parsed scoped tree
instead of fabricated depth-0 siblings.

Michał Pierzchała 6a8beb653e feat(mcp): compact server instructions in both eras + MCP-only help tool (#1839)
* feat(mcp): compact server instructions in both eras + MCP-only help tool (#1833)

MCP-only clients got no workflow guidance: server/discover carried two
sentences, legacy initialize carried nothing, and the CLI guides
(agent-device --help, help <topic>) were unreachable over MCP.

- MCP_SERVER_INSTRUCTIONS: one MCP-phrased workflow card (<2 KB, the
  Claude Code truncation limit) returned by server/discover and legacy
  initialize alike.
- help tool, router-owned (not a command descriptor): no topic -> the CLI
  decision card; topic -> agent-device help <topic|command> text, prefixed
  with the one-line CLI->tool-property mapping; unknown topic -> isError
  listing the topics. listCommandTools() stays descriptor-only for the AI
  SDK; the router composes descriptors + help.
- Move src/cli/parser/cli-help{,-overview}.ts to src/cli-schema/ so
  src/mcp (rank 3) can import the renderers without a layering back-edge
  into src/cli (rank 6).

* fix(mcp): name terminal-only commands in help guides; colocate cli-help tests with their sources

- The MCP guide preamble claimed every `agent-device <command>` line is a
  tool of that name; `help web` tells the reader to run `web setup` /
  `web doctor` and no `web` tool exists. The preamble now lists the exact
  CLI-only set (listCliCommandNames minus listMcpExposedCommandNames) —
  derived, not scanned out of prose where `device`/`web` are ordinary
  words. Regression: help web names `web` as terminal-only, and the listed
  set equals the registry difference.
- cli-help-*.test.ts move from src/cli/parser/__tests__ to src/cli-schema/
  to mirror the moved sources.

* perf(mcp): tighten the guide card, tool description, and preamble

Instructions card 1572 -> 1378 bytes (paid every session), tool
description and preamble trimmed, HELP_TOOL built once as a const.
Bundle delta vs main 3189 -> 2715 bytes; the remainder is the guide text
itself, which the bundle carried in no MCP-phrased form before.

#1779 added src/daemon/handlers/snapshot-interactor-capture.ts as a

edges are value imports, and it sits on the path
request-generic-dispatch -> snapshot-capture -> (seam) -> core/interactors
-> register-builtins -> command-catalog -> ... -> daemon-command-registry,
so it joined the largest type-level SCC (46 -> 47 files, daemon-server
16 -> 17) and R9/R10 have failed on main since d76e0f94e.

Load the interactor registry lazily, the same way
platform-runtime-local-application-interactors.ts reaches
core/interactors from above: the seam module is readable without the
interactor graph behind it, and the SCC is back at 46/16.

pnpm check:layering, typecheck, lint, and vitest src/daemon are green.

handleSessionReplayCommands becomes the routing decision alone; the test suite's harness-flag admission, request translation and scheduler run move to session-test-suite-command.ts beside the replay runtime they already sit next to. Pure move: no behavior change.

* test: pin the replay handler's routing decisions

session-replay.ts is a router now, so it gets a focused test of its own (AGENTS.md 1:1 source/test topology): replay reaches the script-source runtime, test reaches the suite command with the whole parameter set, and an unrelated command is declined. Both destinations are mocked so a wrong edge shows up as the wrong marker; each case was proven red by mutating the routing it pins.

Michał Pierzchała a853734f0c fix(webdriver): give cloud session creation its own budget and stop leaking billed sessions (#1782)
* fix(webdriver): give cloud session creation its own budget and stop leaking billed sessions

Cloud lease allocation ran under the generic 30s/1-retry request policy, so
BrowserStack iOS real-device session creation (45-90s) aborted client-side at
~60s on most runs. Each timed-out POST /session still completed server-side and,
being non-idempotent, was retried — leaving two billed provider sessions per
failed open with no id to release them.

- POST /session is its own phase: a 180s create budget (default), zero retries,
  and no request-bound abort, so the daemon always learns the session id.
- lease_allocate carries a 300s allocation budget surfaced to providers as
  LeaseLifecycleContext.deadline, and a matching 330s client envelope that
  preserves the daemon on timeout (a reset would SIGKILL mid-create and orphan
  every billed session the daemon held).
- The request's cancellation signal is ownership evidence: a session that
  completes after the requester left is released, not registered; a create that
  the transport gives up on surfaces typed evidence (provider + lease) so an
  operator can find and stop the maybe-orphaned session.

Closes #1774

* refactor: one canceled-request error, and tighten the #1774 shapes

Review pass over the session-create fix:

- The canceled-request error had nine hand-rolled copies (src/request/cancel,
  maestro shared, exec, retry, install-source x2, and the new provider one).
  It now has one definition in @agent-device/kernel/errors:
  createRequestCanceledError(details?, cause?) + isRequestCanceledError +
  REQUEST_CANCELED_REASON. Callers add evidence or a sharper hint; the reason
  itself is not overridable, so nothing can build one the predicate misses.
- lease_allocate's timeout bundle moves beside INSTALL_TIMEOUT_POLICY in the
  registry (same {...DEFAULT, envelopeMs, onTimeout} shape); the request timeout
  constant stays exported from timeout-policy like its siblings.
- Transport: fetch helper returns Response's own ok/status; the timeout reason
  const is private behind isWebDriverRequestTimeout.
- Client: one-use options type inlined; the two deadline helpers share one floor.
- Session-manager tests: shared makeRuntime/jsonResponse/afterEach restore.

Net -29 lines with the feature in.

* chore: keep the canceled-request reason private to the kernel

* fix: typed cancellation everywhere + own the AWS remote-access ARN through startup

Second-order follow-ups the #1774 refactor made cheap:

- markRequestCanceled aborts the request signal WITH the kernel's typed
  canceled error as its reason. Every signal.throwIfAborted(), aborted fetch,
  and 'throw signal.reason' in the daemon (20+ sites) now surfaces a canceled
  request as such instead of a bare DOMException that normalized to UNKNOWN —
  and no site has to know the factory exists.
- AWS Device Farm prepareSession owns the remote-access ARN from the moment
  create-remote-access-session answers: a startup timeout, the allocation
  deadline, or a canceled request now stops it before the failure surfaces
  (previously a timed-out startup left a RUNNING billed session behind — the
  same leak class as the WebDriver session, one phase earlier). The startup
  wait is capped by LeaseLifecycleContext.deadline and wakes on cancellation.
- BrowserStack's pre-session local app upload honors the request signal (an
  upload is not billed, so plain abort is right there).
- lease_heartbeat/lease_release share lease_allocate's preserve-daemon policy:
  the rationale — the daemon owns billed sessions; a reset orphans them all —
  applies verbatim.

Each AWS ownership test proven red without the guard (3/3).

* refactor: dedupe billed-resource cleanup and lease-signal wiring

Shrink pass — same behavior, less duplication:

- releaseOnFailure(primaryError, release) in webdriver-utils replaces the two
  identical 'best-effort stop the billed resource, attach cleanupError to the
  primary AppError' helpers (WebDriver session + AWS remote-access ARN); shared
  errorMessage too.
- The lease handler pulls the request signal from getRequestSignal(requestId)
  like every sibling handler, instead of threading a requestSignal arg through
  LeaseHandlerArgs and the request-handler chain. Drops the field, the wiring,
  and five mechanical test edits; the handler test now proves the request-bound
  signal (abort it, watch the provider's signal flip) rather than arg identity.
- Inlined the one-use requestHeaders back into fetchWebDriver.

Handler-signal test proven red without the wiring.

* fix(lease): the daemon releases a lease allocated for a gone requester; honest release evidence

Review follow-up. The provider was doing the daemon's job: it treated the request
signal as 'ownership evidence, not an interrupt' and needed three paragraphs to
say so. The daemon owns the request, so it now decides — generically, for every
provider — what happens to a lease that finished allocating after its requester
left: release it (provider + registry) and answer with the canceled error.

- lease.ts: after allocate returns, isRequestCanceled(requestId) →
  releaseAllocationForGoneRequester(). Release evidence is claimed ONLY on a
  clean release (no warnings, no throw); a WEBDRIVER_SESSION_DELETE_FAILED
  release is reported released:false with providerSessionId + a stop-by-hand
  hint (thymikee's finding: the previous evidence was success-shaped even when
  DELETE failed).
- WebDriverSessionManager: the createOwnedSession/releaseCanceledSession trio is
  gone; allocate is plain 'create with a budget; on failure clean up' again.
- LeaseLifecycleContext.signal is just cancellation, like everywhere else; the
  ownership-semantics comments on the contract, client, registry, AWS prepare and
  utils shrink to what the code no longer says itself.
- Tests: the two provider-level cancellation tests move to the daemon handler
  (where the logic now lives), plus the failing-DELETE regression; both proven
  red without the post-allocate check.

* fix(aws): the allocation deadline bounds remote-access startup, not the 120s default

Live iOS real-device run: startup needed ~128s and hit the standalone 120s
default while the daemon's 300s allocation budget still had room — the new
ownership guard correctly stopped the ARN, but the open failed for no reason.
When the daemon supplies a deadline it is the bound; the default only applies
standalone. Rerun: open in 112s, snapshot, clean close, session STOPPING.

* test(aws): pin that the allocation deadline outlives the 120s startup default; drop empty import

Review follow-ups on 7f9d1481a: a virtual-clock test (Date.now advanced 10s per
poll, RUNNING at 150s, deadline 300s) that fails on the old min(default,
deadline) logic and passes now; and the empty 'import {} from kernel/errors'
left in maestro/shared.ts is removed.

* refactor: finish the dedupe — one release path, kernel errorMessage, AWS on releaseOnFailure

Code-quality review at 7f9d1481a:
1. aws-device-farm.ts still carried its own copy of releaseOnFailure (the dedupe
   commit's script aborted before reaching it and I mis-verified). Now uses the
   shared helper; private copy deleted.
2. Empty 'import {} from kernel/errors' in maestro/shared.ts removed (273870099).
3. errorMessage() lives in @agent-device/kernel/errors; the two copies this PR
   had added (lease.ts, webdriver-utils.ts) import it. Sweeping the pre-existing
   copies is a follow-up.
4. lease.ts has ONE release path: releaseLease(registry, provider, lease,
   request, ctx) → { released (registry), provider } used by both the
   lease_release case (wire shape unchanged) and the gone-requester branch, which
   folds a throwing provider release into releaseError. 'released' now means the
   same thing in both; the provider verdict is a separate 'providerReleased'
   (warnings-free, no throw) that drives the stop-by-hand hint. -~35 lines.
5. sessionCreateTimeoutMs is Omit-ed at the WebDriverTransportOptions boundary
   instead of Pick-ed back out internally.

* fix(lease): 'released' on a canceled allocation means the billed session is confirmed gone

Re-review at 3665ea06: unifying the release path had made the cancellation
error report released:true from the daemon's registry record while the provider
DELETE had failed — success-shaped again, with the operator verdict demoted to
a second key. Fixed at the source of the ambiguity:

- LeaseReleaseOutcome names its bookkeeping field registryReleased.
- On the canceled error, 'released' is true only when registryReleased AND the
  provider released without warnings AND without throwing; the registry record
  is exposed as 'registryReleased'. The stop-by-hand hint keys on 'released'.
- lease_release keeps its existing wire field ('released' = registry; provider
  cleanup rides in 'provider'), unchanged.
- Regressions: failed DELETE and throwing release both pin released:false /
  registryReleased:true (+ providerSessionId, warnings|releaseError, hint);
  both proven red on registry-only semantics.

* ci: retrigger default-setup CodeQL

Run 32051017472 is wedged on GitHub's side: status=completed with
Analyze (python) still queued and Analyze (java-kotlin) failed only at SARIF
upload (503, 'No server is currently available'). It can be neither cancelled
nor rerun, and default-setup CodeQL has no dispatchable workflow, so a new push
is the only way to get a fresh run. No source change.

* test(webdriver): assert the typed timeout contract on the shared-budget probe

main's #1790 tightened this test to expect the raw TimeoutError DOMException,
which this PR intentionally normalizes into AppError{reason:
webdriver_request_timeout}. On the merge ref the two met and Coverage went red.
The regression now asserts the structured contract and that the second request's
budget is the shared remainder (~118ms of 200 after an 80ms first call).

Michał Pierzchała 4b44c1c53a chore(test): remove the contention retry and shrink the subprocess-stub project (#1781 A4) (#1827)
The enumerated single-retry policy (#1419) has fired zero times since it
landed on 2026-07-29: 0 of 234 sampled Coverage-job lane envelopes
(2026-08-11 to 2026-08-18) have retryCount > 0, and none of 17 recent
failed runs was retried (5 refused "outside the enumerated retry list",
4 refused "unhandled error"). All three trackers its entries pointed at
(#1098, #1414, #1419) are closed. It cost ~1,454 LOC, a per-run secret
marker threaded through a setup file on every Vitest project, and a
standing obligation for every future gate reporter to call the blocker
bus.

Delete the scripts, tests and fixtures, the check:contention-retry
script and gate, the envelope artifact upload, and the runner-timeout
setup file; test:coverage:ci is a plain `vitest run --coverage` again.
lane-envelope.ts stays: the mutation, fuzz and concurrency-torture lanes
build their envelopes from it. run-blocker-bus.ts goes: its only
consumer was the retry's failure sink, and its only publisher already
fails the run by setting process.exitCode.

Keep the subprocess-stub project for the three files that really spawn
(client-metro, fuzz harness, fuzz corpus-replay) and drop the three that
run in 31/212/277ms in CI, which cannot contend for anything. The list
is now a plain array in vitest.config.ts with the reason at each entry.
Membership and the project's kill criterion live in #1823.

Because test:coverage:ci is a bare vitest run, the gate manifest reads
its projects directly, so OPAQUE_RUNNERS no longer needs it and an
unrun Vitest project becomes unrepresentable rather than detected; the
audit test now constructs that state by project-scoping the script.

Michał Pierzchała 60f6356b04 fix: read replay scripts on the caller and ship them with the request (#1810)
* fix: read replay scripts on the caller and ship them with the request

Closes #1802

* test: assert the caller-side replay path as a substring, not a hand-escaped regex

* perf(cli): load the Maestro engine only when a replay entry is a flow

The command registry evaluates every command family on CLI startup, so the replay script-source builder's static @agent-device/maestro import put the YAML parser on the --help path. It now loads on demand behind the format check, and the startup import-closure guard covers the engine the way it already covers node:http.

* refactor: share the replay request field vocabulary across the CLI and client views

The new replay script-source flags appear in both CliFlags and CommandExecutionOptions, which fallow flagged as a clone; ReplayRequestFields declares them once. The test-suite handler's missing-sources rejection now travels the typed-error path its sibling rejections already use, so the fix adds no branch to handleSessionReplayCommands.

Michał Pierzchała 3908559fe2 fix: report real claim results from daemon stop (#1818)
* fix: report real claim results from daemon stop

`daemon stop` typed `claimsReleased`/`claimsOrphaned` as the literal `[]` and
every path hardcoded them, so a graceful stop that released a device claim still
reported none (#1799 observation 3, #1320 acceptance). Graceful teardown now
records each session's claim outcome — released after a clean teardown, orphaned
when teardown left the claim in place — into the daemon shutdown report, and the
CLI merges them alongside provider releases. Forced and not-running stops stay
empty because they cannot know, and a report written before claim reporting
still reads its provider releases.

* fix: classify daemon stop claim results from the clear outcome

`clearDeviceClaim` deliberately resolves without deleting when the on-disk claim
is no longer the one it acquired, so the shutdown ledger's "the call resolved"
test reported a successor's claim as released — a device the daemon never freed,
counted as freed.

`clearDeviceClaim` now returns a typed outcome (`deleted` | `absent` |
`ownership-changed`) instead of nothing, and the ledger classifies from it:
released only when absence is confirmed, and a new `superseded` bucket for a
claim another owner had already taken over. Superseded is neither released (this
daemon freed nothing) nor orphaned (no claim of ours remains to reconcile), so
folding it into either would break that list's meaning; it also raises a warning
so a device now owned elsewhere cannot pass silently.

Michał Pierzchała 8d0de32ba4 fix(android): let a covering sibling hide only what its content covers (#1808)
* fix(android): let a sibling hide only what its content covers (#1806)

pruneAndroidCoveredSubtrees credited a higher drawing-order sibling with
painting its whole box as soon as it had any content anywhere inside it,
or a label of its own. A full-screen DoraemonKit drag surface holding one
189px floating icon therefore condemned the entire app subtree, and an
empty labelled match_parent placeholder did the same.

Occlusion is now spatial. A subtree's footprint is the bounding box of
what it presents (agent targets and labelled leaves); a sibling is covered
when its footprint lies under a candidate's footprint. A node's own label
is no longer paint evidence: a container's content-desc describes its
children and an empty labelled View draws nothing. Only a touch target
still hides its full box (scrims). Comparing footprint to footprint keeps
stacked screens with matching margins registering as covered.

Live on a Pixel 9 Pro XL API 37 emulator with a DoKit-shaped overlay
added to the test app: snapshot -i went from 2 nodes + the sparse hint to
the full app; helper-XML A/B across home/catalog/form/product-detail
recovered every label with none lost, and non-overlay screens are
byte-identical.

* fix(android): measure occlusion by overlapped area, not bounding box

Review on #1808: a bounding box of two corner controls spans the
viewport, so a transparent overlay with a control in each corner still
acquired a full-screen footprint and could prune the app beneath it.

Footprints now keep their presented rects apart, and coverage is the
overlapped area of the two unions (coordinate-compressed cell sweep).
Scrollables count as presenting their box: they consume touches over it,
which is what lets a real pushed screen (header, scrollable body, footer)
still cover a drawer surface. Adds the disconnected-corner regression.

* fix(android): count what a covered sibling shows, not only what it paints

Fuzzing random sibling trees old-vs-new surfaced the one direction the
footprint model could still regress: a container whose only painted
content is small (one corner icon) but which also carries labelled
containers or testID-only markers was condemned as soon as a touch
surface covered that icon, since markers and container labels are not
paint and never entered the footprint.

Footprints now carry two rect sets. `paints` (touch targets,
scrollables, labelled leaves) is what a candidate can cover with; it
still excludes identifiers and container labels, or the DoKit fix would
unwind. `shows` adds every labelled or identified node and is what a
covered sibling must lose in full. Focusable-only nodes no longer paint
their box either, matching #1733 for descendants as well as siblings.

Adds the marker regression. Re-fuzzed 20k trees: new-prunes-more is down
to 0.14 %, all of the class where everything the target shows lies under
a higher touch/scroll surface. Live captures unchanged.

* test(android): pin that focusability never paints a covering candidate's box

A full-screen focusable wrapper holding one clickable icon is a covering
candidate; the lower app content must survive. Fails when paintsOwnBox
counts focus targets again.

Michał Pierzchała 2b6d04a13e fix: enforce device claims for sessionless device mutations (#1809)
`boot` and `shutdown` never consulted the host-global device claim store, so a
daemon in one state directory could terminate an emulator another daemon held a
verified-live claim on and report success (#1799).

Rather than adding a claim check to those two handlers, this makes the class
unrepresentable: `CommandDescriptor` gains a REQUIRED `deviceClaimPolicy` trait
(#1320's vocabulary), and the request-execution scope enforces it where the
request runtime bindings create a device binding — the one seam through which
any handler can obtain device operations, and already the place per-device
deduplication lives. A `transient-exclusive` command acquires a command-scoped
claim before operations reach the handler, refuses a foreign live claim with the
existing DEVICE_IN_USE/DEVICE_CLAIM_LIVE_OWNER error, and releases in the
scope's finally. Every other policy performs no claim-store I/O, so session-bound
commands keep #1320's non-goal intact.

Michał Pierzchała 0f4f322878 fix: reject selector-shaped wait arguments instead of reading them as text (#1813)
`wait <condition> '<selector>' [timeoutMs]` (e.g. `wait open 'label="Open"' 25000`,
`wait exists 'label="x"' 100`) and any unrecognized `key=value` token used to fall
through parseWaitPositionals' text fallback and wait out the full timeout for
literal text that could never appear on screen — reading as a false "element
absent" instead of the caller's own argument mistake (#1035 is the sibling fix
for click/press/fill/get).

parseWaitPositionals now returns a typed `invalid` variant whenever a positional
token is selector-shaped (a recognized key, or an unrecognized key=value) but the
list doesn't form a valid selector expression, or a valid selector prefix is
followed by unquoted trailing tokens. The message names the offending token,
points condition words (exists/present/appears/gone/disappears) at the selector
form, and always offers the explicit `wait text '<text>'` escape hatch. Bare text
(single- and multi-word) and the explicit `text` keyword form are unaffected.

Excluding `invalid` from the type consumed by selector-runtime's toWaitTarget
makes the remaining kind-by-kind narrowing exhaustive without a runtime fallback
branch.

Michał Pierzchała 801734d433 feat(ai-sdk): add agent-device/ai-sdk tool set and document the MCP zero-code path (#1804)
* feat(ai-sdk): add agent-device/ai-sdk tool set and document the MCP zero-code path

Adds `createAgentDeviceTools()` under a new `agent-device/ai-sdk` subpath,
built from the same command registry the MCP server uses so both stay in
lockstep without a hand-maintained tool list. Introduces a `frameworkTier`
descriptor facet ('core' | 'extended') so the factory can default to a
curated perceive/act loop instead of handing a model dozens of tools.

`ai` is wired as an optional peer dependency, imported lazily inside the
factory rather than at module scope, so importing the subpath itself never
requires `ai` to be installed - only calling it does. The package's own
publishing gate (scripts/lib/shipped-imports.ts) is extended to recognize
peerDependencies as a valid resolution source, since this is the first
optional peer this package has shipped.

Also restructures the AI SDK doc around three tiers (zero-code via
@ai-sdk/mcp, the new typed tool set, hand-written tools) and fixes a stale
`needsApproval` reference in favor of the current `toolApproval` API.

* fix(layering): classify src/ai-sdk as a rank-4 zone

The layering guard requires every src/<folder>/ to be explicitly ranked or
unranked; the new src/ai-sdk/ subpath (added in the prior commit) was left
unclassified, failing CI's Layering Guard job. It sits at the same tier as
client/compat/daemon-server/metro/remote/sdk - a public integration surface
consuming mcp (3) and core (2), imported by nothing else in the tree.

* fix(ci): cover, exempt, and pack the new ai-sdk subpath

Fixes the remaining CI failures on the ai-sdk subpath commit:

- Coverage: src/ai-sdk/index.ts had no dedicated unit test (only manual/
  integration verification), so changed-line coverage sat at 6.9% against
  the 70% gate. Adds src/ai-sdk/__tests__/index.test.ts (core vs 'all' tool
  filtering, session/platform pinning and schema hiding, error
  normalization, toolApproval passthrough) with createCommandToolExecutor
  and createAgentDeviceClient mocked the same way command-tools.test.ts
  does, plus a dedicated missing-peer-dependency.test.ts that mocks `ai`
  itself to throw, isolated to its own file so it doesn't affect the other
  tests' use of the real, installed `ai` package. Changed-line coverage is
  now 29/29 (100%).
- Fallow Code Quality: src/ai-sdk/index.ts and examples/sdk/ai-sdk-tools.ts
  are entry points with no in-repo importer (reached only via package.json
  exports / run directly), and the new subpath's exports are unused
  internally by design - both need the same treatment src/sdk/*.ts and its
  examples already have in .fallowrc.json.
- Integration Tests: test/integration/installed-package-metro.test.ts and
  src/__tests__/package-exports.test.ts each hand-list every published
  subpath and smoke-check it from a real packed install; added ./ai-sdk to
  both so the new subpath is actually exercised, not just silently passing.

* fix(ai-sdk): hide MCP transport/config fields from the model too

createAgentDeviceTools() only removed session and mcpOutputFormat from tool
schemas. stateDir was still model-visible and reached the shared executor
as client configuration, letting a tool call redirect into a different
daemon state directory - defeating the "one pinned session" guarantee the
factory exists to provide. includeCost and responseLevel are MCP
tool-config knobs in the same category, irrelevant to this adapter.

Widens the hidden-field set to session/stateDir/mcpOutputFormat/
includeCost/responseLevel, and now strips them from the runtime input
inside execute() too (not just the schema), so the guarantee holds even if
a caller bypasses schema validation. The schema-properties filter and the
input filter now share one omitHidden() helper instead of two near-
duplicate implementations.

Addresses the P1 review comment on #1804.

Michał Pierzchała 20458cbcf6 fix(daemon): reject '.', '..' and empty session names at resolveSessionDir (#1815)
safeSessionName only rewrites characters outside [a-zA-Z0-9._-], so the names
'.' and '..' survive unchanged and path.join resolves them to the sessions dir
itself or its parent, the daemon state dir. A remote caller's --session ..
would then land app.log / runner.log / requests/*.ndjson outside the sessions
tree.

SessionStore.resolveSessionDir is the one place a session name becomes a
directory (AGENTS.md: session artifact paths come from session-store), so it now
refuses such a name with INVALID_ARGS. Every request goes through it first
thing in createRequestExecutionScope, before any artifact path is used, so this
is also the admission-time rejection; every other caller passes an already
admitted name.

isSafeSessionSegment mirrors the predicate PR #1814 adds for its
request-diagnostics route; whichever lands second takes the trivial merge.

Regression tests were proven red against the pre-fix code: resolveSessionDir
returned the sessions dir / state dir for '.', '..', '' and the request scope
resolved runnerLogPath to <stateDir>/runner.log.

Michał Pierzchała 8db36299e4 feat(web): add hover command for hover-gated UI (#1783) (#1786)
* feat(web): add hover command for hover-gated UI (#1783)

Add a first-class `hover <x y|@ref|selector> [--settle]` verb, admitted on
web only, that moves the pointer without pressing via the agent-browser
backend (mouse move). It rides the existing targeted-touch pipeline
(ref/selector/coordinate resolution, occlusion/off-screen guards, settle
observation, response builder, recording) through a new optional
Interactor/backend `hover` op that only the web provider implements.

Touch platforms have no hover state: capabilities advertise it on web
only and iOS/Android/Linux reject it at admission with a --platform web
hint; longpress stays the mobile hold-gesture verb.

Closes #1783

* fix(hover): native hoverRef route for web @ref, android coverage pin, revert skill edit

Review follow-ups on #1786:
- hover @ref on web now dispatches through the provider's own element handle
  (agent-browser `hover <ref>`) via a new backend hoverTarget, mirroring
  click/fill's ADR 0011 native-ref path — web ref frames carry no rects, so
  the coordinate route could never resolve them. The shared preflight +
  exact-ref dispatch is extracted into dispatchNativeRefInteraction and used
  by tap/fill/hover; the guarantee matrix native-ref row now lists hover.
- Daemon regression test is production-faithful: rect-less web ref frame,
  scoped provider, asserts no coordinate dispatch. Selector→coordinate and
  provider hoverRef tests added.
- Android emulator coverage summary pin 2/53 → 3/54.
- skills/agent-device/SKILL.md reverted (out of scope, AGENTS.md rule).
- Docs/help disclose that --settle with @ref on web shares click's existing
  limitation; use a selector or coordinates for the settled diff.

* test: drive hover through the apple output guard; cover direct hover dispatch

The provider-integration apple-leak guard partitions every public command
into driven/skipped; hover was neither, which failed Integration Tests and
took Coverage down with it. Drive it (it reaches the Apple capability
refusal, which is scanned like any other error response). Also cover the
direct-dispatch handleHoverCommand seam.

* test(web): drive hover @ref in the provider-backed web scenario

The integration-progress gate requires every public command to be referenced
by a provider-backed scenario. Add hover @ref to the web desktop flow: it
must reach the provider's hoverRef handle (never a coordinate) and be
recorded on the session without fabricated x/y, like click @ref.

Michał Pierzchała 681cad2222 test: assert the specific error code instead of any failure (#1781 B4) (#1790)
Converts the 20 test assertions across the repo that accepted ANY
failure (bare `expect(...).toThrow()`, bare `assert.throws(fn)`, bare
`assert.rejects(p)`) into assertions on the specific AppError `code`
each test is actually about, or — where the propagated error is
genuinely opaque (a mocked upstream failure whose identity, not its
shape, is the point) — identity assertions with a comment explaining
why.

Added a synchronous `assertThrowsAppError(fn, {code, message?})`
sibling to the existing `assertRejectsAppError` helper in
src/__tests__/test-utils/app-error.ts, exported via the test-utils
index, for the two src/ sites that needed it.
packages/provider-limrun and packages/provider-webdriver have no
test-utils dir and cannot import from src/, so those sites use
vitest's `expect(...).toThrow(expect.objectContaining({ code }))` or
an inline `assert.rejects(p, matcherFn)` instead.

Sites converted:
- packages/provider-limrun/src/app-log-runtime.test.ts:153-155
  (bare `.toThrow()` x3 -> `UNSUPPORTED_OPERATION`)
- src/daemon/__tests__/app-log.test.ts:39 (bare `.toThrow()` ->
  message match; plain Error, not AppError, from verified-file's
  identity check)
- src/daemon/__tests__/resumable-upload-range.test.ts:13 (bare
  `assert.throws(fn)` -> `INVALID_ARGS`); also fixed line 19's
  `assert.throws(fn, value)`, a documented Node.js gotcha where a
  string second argument is the failure message, not a matcher, so
  it was equally bare in effect
- packages/provider-webdriver/src/webdriver-client.test.ts:229 (bare
  `assert.rejects(p)` -> asserts the raw AbortSignal.timeout()
  rejection's `name`, since the transport re-throws it unwrapped)
- src/daemon/handlers/__tests__/session-device-claims.test.ts:129,
  151, 174 (bare `assert.rejects(p)` x3 -> identity assertions; each
  test's point is device-claim rollback/retention around an opaque
  mocked upstream failure)
- src/platforms/android/__tests__/settings.test.ts:109 (bare
  `assert.rejects(p)` -> `UNSUPPORTED_OPERATION`)
- src/platforms/android/__tests__/snapshot.test.ts:1071, 1342 (bare
  `assert.rejects(p)` x2 -> `COMMAND_FAILED` + message)
- src/platforms/android/__tests__/touch-helper-session.test.ts:526
  (bare `assert.rejects(p)` -> `COMMAND_FAILED`, wrong-protocol
  message)
- src/platforms/apple/core/__tests__/runner-command-retry.test.ts:472,
  527, 550, 762, 881, 1016 (bare `assert.rejects(p)` x6 ->
  `COMMAND_FAILED` with the recovery-path-specific details/message)
- src/platforms/apple/core/__tests__/runner-transport.test.ts:61
  (bare `assert.rejects(p)` -> identity assertion; fetchWithTimeout
  does not wrap fetch() failures into an AppError)

No repo-wide scanner/lint rule added (explicitly out of scope per
#1781); no test loosened.

Michał Pierzchała f378050586 feat(snapshot): attach a fallback screenshot to sparse captures (#1764)
A sparse verdict already tells the caller to use a screenshot as visual truth,
which made that screenshot the guaranteed next command on every unreadable
screen — a second round trip to obey advice we authored. The user-facing
`snapshot` dispatch now takes the shot itself and links the path in its
warnings.

The fallback is deliberately hung off `dispatchSnapshotViaRuntime` and skipped
for internal observations: selector resolution, settle, and wait polling reach
`captureSnapshot` directly, so a wait polling an unreadable screen cannot turn
into a screenshot per poll. A failed shot is swallowed — the verdict's own
warning still carries the manual remedy, so the fallback can never fail the
snapshot that was asked for.

Sparse captures also say when the screen is the app's problem. Only the
`sparse-tree` reason code is evidence about the app: every backend reached the
screen and it published no semantic content, which is the same emptiness
assistive tech gets. `ax-rejected`, `budget`, `no-nodes` and `capture-failed`
are limits of this tool and stay unattributed, so readers are not sent to file
bugs against code that is not broken.
