Type-checked against the API 36 framework jar (tools/androidcheck); assembleDebug still needs the SDK Co-Authored-By: Claude Fable 5.1 Claude-Session: https://claude.ai/code/session_01Vyo2hxtfWppNVyy99Q8GmZ --- app/src/main/AndroidManifest.xml | 109 ++++++++++ .../com/thatsimpletech/assist/AssistApp.kt | 51 +++++ .../assist/a11y/AssistAccessibilityService.kt | 43 ++++ .../assist/a11y/NodeExecutor.kt | 194 ++++++++++++++++++ .../assist/a11y/TreeObserver.kt | 54 +++++ .../thatsimpletech/assist/a11y/TreeWalker.kt | 159 ++++++++++++++ .../assist/approval/AndroidApprovalSurface.kt | 49 +++++ .../assist/approval/ApprovalNotifier.kt | 87 ++++++++ .../assist/approval/ApprovalReceiver.kt | 24 +++ .../assist/approval/ApprovalRequests.kt | 28 +++ .../assist/approval/OverlayCard.kt | 103 ++++++++++ .../assistant/AssistInteractionService.kt | 46 +++++ .../assist/audit/AndroidSqlExecutor.kt | 45 ++++ .../thatsimpletech/assist/kill/KillSwitch.kt | 34 +++ .../assist/kill/KillSwitchTile.kt | 31 +++ .../notif/AssistNotificationListener.kt | 89 ++++++++ .../assist/secrets/KeystoreSecretStore.kt | 76 +++++++ .../assist/task/TaskController.kt | 12 ++ .../assist/task/TaskForegroundService.kt | 67 ++++++ .../thatsimpletech/assist/ui/MainActivity.kt | 126 ++++++++++++ app/src/main/res/values/strings.xml | 13 ++ .../res/xml/accessibility_service_config.xml | 14 ++ app/src/main/res/xml/interaction_service.xml | 8 + .../main/res/xml/network_security_config.xml | 10 + 24 files changed, 1472 insertions(+) create mode 100644 app/src/main/AndroidManifest.xml create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/AssistApp.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/a11y/AssistAccessibilityService.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/a11y/NodeExecutor.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/a11y/TreeObserver.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/a11y/TreeWalker.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/approval/AndroidApprovalSurface.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/approval/ApprovalNotifier.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/approval/ApprovalReceiver.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/approval/ApprovalRequests.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/approval/OverlayCard.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/assistant/AssistInteractionService.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/audit/AndroidSqlExecutor.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/kill/KillSwitch.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/kill/KillSwitchTile.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/notif/AssistNotificationListener.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/secrets/KeystoreSecretStore.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/task/TaskController.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/task/TaskForegroundService.kt create mode 100644 app/src/main/kotlin/com/thatsimpletech/assist/ui/MainActivity.kt create mode 100644 app/src/main/res/values/strings.xml create mode 100644 app/src/main/res/xml/accessibility_service_config.xml create mode 100644 app/src/main/res/xml/interaction_service.xml create mode 100644 app/src/main/res/xml/network_security_config.xml diff --git a/app/src/main/AndroidManifest.xml b/app/src/main/AndroidManifest.xml new file mode 100644 index 0000000..dd964e8 --- /dev/null +++ b/app/src/main/AndroidManifest.xml @@ -0,0 +1,109 @@ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + diff --git a/app/src/main/kotlin/com/thatsimpletech/assist/AssistApp.kt b/app/src/main/kotlin/com/thatsimpletech/assist/AssistApp.kt new file mode 100644 index 0000000..5ee83d9 --- /dev/null +++ b/app/src/main/kotlin/com/thatsimpletech/assist/AssistApp.kt @@ -0,0 +1,51 @@ +package com.thatsimpletech.assist + +import android.app.Application +import android.database.sqlite.SQLiteDatabase +import com.thatsimpletech.assist.a11y.AssistAccessibilityService +import com.thatsimpletech.assist.approval.AndroidApprovalSurface +import com.thatsimpletech.assist.approval.ApprovalNotifier +import com.thatsimpletech.assist.approval.OverlayCard +import com.thatsimpletech.assist.audit.AndroidSqlExecutor +import com.thatsimpletech.assist.core.policy.PolicyPack +import com.thatsimpletech.assist.core.secrets.SecretStore +import com.thatsimpletech.assist.secrets.KeystoreSecretStore +import java.io.File + +class AssistApp : Application() { + override fun onCreate() { + super.onCreate() + Graph.init(this) + } +} + +/** + * The app's object graph, by hand.

full task wiring - CloudPlanner: one brain-tier chat call per step, metered; spend cap turns into an ask line so the turn ends cleanly - AuditListener: every step, approval and model call is an INSERT

Sep 17 00:00:00 2001 From: Claude Date: Mon, 7 Sep 2026 19:06:41 +0000 Subject: [PATCH 19/34] wire: sockets come from Endpoints, not a raw OkHttp factory The net module's source scan (the no-telemetry promise) caught the wire client holding its own OkHttpClient factory. It now asks Endpoints for the WebSocket client, so the host is checked against config before any connection exists.

The real door remains `Endpoints`: a host that is not on the active preset is refused before a socket opens. On-device LiteRT is still an honest refusal. +## TM-016 (2026-09-08) Closed verbs for non-tree actions + +M2 non-tree work (calls, texts, alarms, timers, calendar, contacts, navigation, flashlight, DND, brightness, volume, media, WhatsApp/Spotify/Gmail, Quick Settings) enters the same closed grammar as tree driving: one new `Verb` / `Action` per line, quoted payloads, `render()` round-trips through `ActionParser`, empty `hints` so a node is not required. A generic `do "…"` is refused; unknown words stay `unknown verb`. + +Adam accepted this table and the §15 defaults that constrain it: + +- **Dial-only.** `call` prepares `ACTION_DIAL`. No `ACTION_CALL` in M2. +- **SMS draft.** `text` prepares `ACTION_SENDTO`. No `SmsManager` in M2. +- **Calendar UI insert.** `event` opens the insert UI. No silent `ContentResolver.insert`. +- **Wi-Fi / Bluetooth.** `qs` then tap a visible tile (Tier 2 via `on_qs`), or `open "Settings"` and tap the row. No `wifi` / `bluetooth` verb and no silent adapter APIs. SystemUI is not allowlisted. +- **Contacts** join the allowlist (`com.google.android.contacts`). `contact lookup` / `contact add` are the two forms of one verb, same pattern as `notif`. +- **No media seek.** `media` / `spotify` are play, pause, next, prev. + +Partner misses are honest errors, not a fall-through to `tap`/`type` (that path is M6). Cards still show `plainWords()` payloads (TM-014). Intent, device, partner, and `qs` verbs are not app-scoped; a WhatsApp tree-`tap` still is. `qs` acts (keyguard refuses it) and is silent when unlocked via the `read-only` verb list, like `back` / `home` / `recents`. + diff --git a/policy/cases.yaml b/policy/cases.yaml index 073fead..2c8570d 100644 --- a/policy/cases.yaml +++ b/policy/cases.yaml @@ -2,7 +2,7 @@ # rule ids.
