From 6e89f2c70a27168d7cb844fa452128adb8c1d006 Mon Sep 17 00:00:00 2001 From: agent Date: Wed, 19 Aug 2026 15:28:32 +0200 Subject: [PATCH 1/5] refactor: migrate is to the request-bound device runtime MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `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. --- scripts/layering/check.ts | 4 +- .../layering/runtime-command-cutover-table.ts | 35 ++- src/core/__tests__/capabilities.test.ts | 3 - .../capability-plugin-routing-parity.test.ts | 3 - src/core/capabilities.ts | 3 +- .../__tests__/parity.test.ts | 1 + src/core/command-descriptor/registry.ts | 3 +- src/daemon/__tests__/is-runtime.test.ts | 241 ++++++++++++++++++ src/daemon/selector-runtime-backend.ts | 40 +-- src/daemon/selector-runtime.ts | 28 +- 10 files changed, 306 insertions(+), 55 deletions(-) create mode 100644 src/daemon/__tests__/is-runtime.test.ts diff --git a/scripts/layering/check.ts b/scripts/layering/check.ts index 7817c3b01..1795b55f0 100644 --- a/scripts/layering/check.ts +++ b/scripts/layering/check.ts @@ -36,8 +36,8 @@ // composition file; premature implementation loading and forbidden cross-boundary edges fail (R13). // - Over COMMAND-ATOMIC RUNTIME CUTOVERS: one parametrized gate reads the migrated-command // table (appstate R22, shutdown R23, boot R20, apps R21, install/deploy R24-R27, -// lifecycle R28-R31, devices R17, logs R14, network R15, record R16, snapshot R32, diff R33) -// and proves each command keeps +// lifecycle R28-R31, devices R17, logs R14, network R15, record R16, snapshot R32, diff R33, +// viewport R34, get R36, is R37 — R35 reserved for find) and proves each command keeps // exactly one platform-execution path — retired routes, admission, modules, and widened // runtime access cannot coexist with its operation-fact-derived descriptor and handler. // - Over CONTRACTS PRODUCTION SOURCE: contracts owns vocabulary only — host, process, and timer diff --git a/scripts/layering/runtime-command-cutover-table.ts b/scripts/layering/runtime-command-cutover-table.ts index ecdf21ca3..2a76c305b 100644 --- a/scripts/layering/runtime-command-cutover-table.ts +++ b/scripts/layering/runtime-command-cutover-table.ts @@ -25,7 +25,8 @@ import { retiredDispatchProjectionViolations } from './runtime-command-cutover-d * A row id is a report heading, so it must be unique across every stack that adds rows here. * `cutoverTableDefects` rejects a duplicate; lifecycle starts at R28 after the accepted * shutdown, install/deploy, and application-lifecycle allocations.

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 " 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.

Neither identifier has ever existed. They satisfied the non-empty shape check while proving nothing — the vacuous registry claim AGENTS.md warns about, and a green gate that would stay green if the deletion were reverted. The cause was the model, not the row. Every `LegacyRetirementClaim` form names something that must NOT exist, which a row can always satisfy by inventing a name. `is` retired no module, route, or dispatch projection because it had none: its legacy admission was a capability bucket plus membership in two static platform command sets, so its real retirement is a DATA deletion the model could not express. Rather than patch around that with sentinels or a per-command policy file — both forbidden by the playbook — this generalizes the model. `staticCommandSets` names the sets themselves and is proven from both sides: each must still be DECLARED in production source, and must no longer list the command. A fictional set fails the first half; a skipped deletion fails the second. That is what an identifier-shaped claim cannot state.

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. --- .../layering/runtime-command-cutover-table.ts | 9 ++ src/daemon/__tests__/is-runtime.test.ts | 113 ++------------ .../handlers/__tests__/interaction.test.ts | 143 ++---------------- src/daemon/selector-runtime.ts | 120 +-------------- .../provider-scenarios/ios-world.ts | 31 +--- 5 files changed, 48 insertions(+), 368 deletions(-) diff --git a/scripts/layering/runtime-command-cutover-table.ts b/scripts/layering/runtime-command-cutover-table.ts index acb23e4da..1e5783e3f 100644 --- a/scripts/layering/runtime-command-cutover-table.ts +++ b/scripts/layering/runtime-command-cutover-table.ts @@ -571,6 +571,15 @@ export const MIGRATED_COMMAND_CUTOVERS: readonly MigratedCommandCutover[] = [ // `is` executes through the shared selector seam, so its capture owners are the SAME // selectors `snapshot`/`diff`/`get` count.
