chore(release): v2026.10.12.2 [skip ci]

The t24 review's four observations on the t23 ADB-off audit. No production code
changes: button.py is untouched, deliberately (see O1).

O1 — THE PAIR ADB CARVE-OUT, ACCEPTED AND NAMED. The button's press builds its own
AdbMediaSessionPoller and connects without ever reading the entry's option. I
searched for a production route that reaches the press with ADB off and found
NONE, so no gate was added:
  * `button.async_setup_entry` is the ONLY place that entity is created, and it
    creates it only while the option is on (button.py:34-35);
  * every options save runs through `NvidiaShieldOptionsFlow(OptionsFlowWithReload)`,
    which reloads the entry and re-runs that setup — so turning ADB off takes the
    button away (config_flow.py:1340-1353);
  * the press is user-initiated in any case — the same class as the already
    declared `test_connect` pairing probe.
It is now a NAMED carve-out in the audit's `CARVE_OUTS` table, with what it does,
why that is safe, and the assertions behind both. The measurement is DRIVEN rather
than quoted: the press is executed with the option OFF and ON and asserted to cost
the same 1 ctor / 1 connect / 1 disconnect, so the carve-out's substance is a test
result and not prose. A meta test checks every carve-out's named assertion really
exists, so a carve-out cannot point at a phantom. MUTATION-CHECKED: making
`async_setup_entry` add the entity unconditionally fails three of the new tests.
The intent button is explicitly NOT a carve-out (it can exist for a disabled entry
and refuses through the t23 accessor gate) — stated in the same entry.

O2 — THE AUDIT NOW EXECUTES WHAT IT NAMES. `_open_logcat_stream` and the logcat
ladder are driven both ways: two new rows in the parametrized `AUDITED_PATHS` table
(so the disabled case costs zero traffic) plus dedicated assertions — the open
RAISES "ADB is switched off" in a `pytest.raises(match=...)`, and the ladder
RETURNS at once with `_logcat_failures == []` and `_logcat_disabled is False`, i.e.
a local option is not booked as a device failure. The anti-overcorrection pin is
kept in the same class: with ADB ON, five real ladder failures DO auto-disable.
MUTATION-CHECKED: removing either t23 logcat gate fails three of these tests.

O3 — THE ROTTABLE FIGURE IS GONE. The statement_blocks bullet no longer states a
count ("currently 28" was stale within one unit of work); the band (~2%) is the
policy, the current walk lives in the header the sweep prints, and the comment now
says why no band carries a count. The relative_imports bullet lost its illustrative
figure for the same reason.

O4 — THE ONE WRITE IS NAMED AS A DEBT. The audit's module docstring now states
exactly what "nothing is cached" means: the single write a disabled path can still
make is `_app_label_failed.add(package)` in `_dump_label` — a retry DEBT, not an
answer. It is pinned by a test: with ADB off the debt is recorded while
`_app_labels` stays EMPTY and the lookup still answers None; with ADB back on the
probe runs, the label is cached and the debt is settled (the discard that the code
already does).

FAIL-CLOSED, CONFIRMED AND LOCATED. The harness change (`entry=None` now reads as
ADB off) matches production because both read the option the same way: the manager
returns "disabled" for a missing option, and `__init__.py` builds no poller for the
same missing option — asserted by two new tests (an entry with `options={}`, and a
manager with no entry at all) and by a source assertion on `__init__.py`'s own
`if not entry.options.get(CONF_ADB_ENABLED, False):`. No production path is
affected: production always constructs the manager WITH the entry, and for an entry
whose option is on nothing changed at all.

No regressions: 942 passed / 5 skipped (V1), 943 / 4 (V2) — the +19 are the new
tests. ruff clean, drift exit 0, the real-HA pattern collects and runs its 3 files.
The device side remains a scripted double: the claim proven is that nothing was
sent, not what firmware would do.

 ### Raw `adb_command` service (opt-in)
 
 When enabled in the integration's options (`adb_command_enabled`, **default
-off**), the integration registers the `nvidia_shield.adb_command` service:
-send a raw ADB shell command to the entry's persistent connection
-(`{"command": "your-command", "entity_id": "media_player.<yours>"}` — the

+off**), the integration registers the `nvidia_shield.adb_command` service: send a
+raw ADB shell command to the entry's persistent connection.
+
+**Picking the Shield in the UI.** The action declares a target, so **Developer
+tools → Actions** (and the automation editor) offers a target picker whose entity
+list contains the Shield's `media_player` entity — the same way the core
+`androidtv` integration's action worked. Select the Shield there, type the
+command, and call it.
+Home Assistant renders that picker from the action's *target description*, which
+the integration publishes at setup — that is why the Shield is selectable at all.
+
+**As YAML / automation data**, the same call:
+
+```yaml
+- action: nvidia_shield.adb_command
+  target:
+    entity_id: media_player.shield
+  data:
+    command: getprop ro.product.model
+  response_variable: adb            # optional: keep the output in a variable
+```
+
+- `command` (**required**) — the shell command. An empty one is an error
+  (`invalid_command`), never a silent no-op.
+- The target (**required**) is the Shield's `media_player` entity, or its
+  `device_id` (`target: {device_id: …}` / `entity_id: …`). There is **no
+  "pick the only one" fallback**: with no target the call fails with `no_target`,
+  two targets fail with `ambiguous_target`, and an entity that does not participate
+  (its entry has the option off) fails with `unsupported_target` — a raw shell
+  command is never sent to a Shield you did not select.
+- **The output comes back** in the response under `adb_response` — the same key the
+deprecated `androidtv.adb_command` action returned, so a template written against
+that integration keeps reading the same field:
+
+```yaml
+- action: nvidia_shield.adb_command
+  target: {entity_id: media_player.shield}
+  data: {command: "getprop ro.product.model"}
+  response_variable: adb
+- action: notify.persistent_notification
+  data:
+    message: "{{ adb.adb_response }}"
+```
+
+  A caller that does not ask for a response is unchanged (the response is
+  *optional*, not required). If ADB is down the action raises `adb_unavailable` —
+  an error, never an empty response; a transport failure mid-command propagates as
+  an error too.
+
+This is the same security posture as the Home Assistant core `androidtv`
+integration: a documented, opt-in escape hatch for debugging and automation,
+registered at setup and unregistered when the last participating entity unloads.
+
+### Intents (buttons and the `send_intent` action)
+
+An **intent** is one thing an app can be asked to do: open a screen, follow a
+deep link, handle an action. This integration carries them over ADB, in two
+halves.
+
+**Discovery** asks the Shield what ONE app advertises. The **Scan an app's
+intents** row on the Intents screen runs it for the app you pick: the resolver
+section of that app's `pm dump` is filtered *on the device* (the whole dump is
+~2241 lines), only the section crosses the connection, and the answer is cached
+per package for an hour. A scan never registers anything — it offers candidates,
+and you pick one. A candidate whose path is a *pattern* (`/title.*`) prefills no
+URL on purpose: a pattern is not a link you can open.
+
+**Registration** turns a candidate (or something you type) into a stored intent.
+Configure → **Intents** → *Add or edit an intent*:
+
+| Field | What it is |
+| --- | --- |
+| Name | what the button and the action's dropdown call it; unique per entry |
+| Package id | the app's Android package id, exactly as the Shield reports it |
+| Activity (component) | the component to launch, `pkg/.Activity` — use this **or** the action |
+| Action | an Android action such as `android.intent.action.VIEW` |
+| Categories | optional, comma separated (`android.intent.category.DEFAULT`) |
+| Data (URL template) | optional URL/URI; `{variable}` placeholders are filled from the declared variables |
+| Variables (declared fields) | one per line: `key:type[:required][=value]`, where type is `string`, `int`, `bool` or `raw` |
+
+**One button per registered intent.** Adding an intent adds `button.<name>`
+pressing it sends the intent with the declared defaults. A declared field that is
+`required` with no default makes the press an error naming the field — such an
+intent is meant to be called through the action, which is where variables come
+from. Removing the intent removes its button (an options change reloads the
+entry). The button's attributes show exactly what it will send.
+
+**The action** takes the intent's name and its variables:
+
+```yaml
+- action: nvidia_shield.send_intent
+  target:
+    entity_id: media_player.shield
+  data:
+    intent: "Netflix: open a title"
+    variables:
+      id: "80100172"
+  response_variable: fired            # optional: keep the output in a variable
+```
+
+- `intent` (**required**) — the registered name, as the Intents screen shows it.
+  An unknown one raises `unknown_intent` and **lists the known names**.
+- `variables` — one value per declared field. A declared field with a default may
+  be omitted; a `required` one raises `missing_intent_field`, **naming the field**.
+  A variable the intent never declared is **refused** (`unknown_intent_variable`):
+  nothing silently travels to the device, and nothing is silently dropped. A value
+  that cannot become its declared type names the field and the value
+  (`invalid_intent_field`).
+- The **target is required** and resolves exactly like `adb_command`: one Shield
+  (`no_target` / `unsupported_target` / `ambiguous_target`), never a guess.
+- **The device's own output comes back** in the response under `intent_response`
+  (`am start` prints `Starting: Intent {…}` when it accepted the intent), so a
+  caller that asks for a response can see what happened.
+- **Failures are loud, and the device's words are kept.** A Shield that refuses
+  the intent raises `intent_failed` carrying *its* message ("unable to resolve
+  Intent", "does not exist", "Permission Denial") — never a silent success. ADB
+  being off, unreachable, or answering nothing raises `intents_need_adb` /
+  `intent_no_answer`: the intents feature **requires ADB**, because the remote
+  protocol cannot carry an intent, and the error says so instead of failing
+  obscurely.
+
+**An intent the app rejects is a configuration problem.** The app may no longer
+handle that action, the component may have been renamed by an update, or the
+intent may need a permission it does not have. The error shows the Shield's own
+message and the fix is the registration — the integration never retries, guesses
+or falls back to another intent.
+
+**How the command is built (and why it is safe).** `am start -n <component>
+-a <action> -c <category> -d <data> --es/--ei/--ez key value`, assembled from the
+stored fields. `{placeholder}` substitution is plain text replacement — **no
+`eval`, no `format()`, no shell interpolation** — and every value is quoted, so a
+variable whose value is `"; rm -rf /"` reaches the Shield as literal data inside
+one argument. This is deliberately **not** a second raw-shell door:
+`nvidia_shield.adb_command` remains that one, and this action can only ever send
+an intent you registered.
+
+### Screen capture (opt-in, manual)
+
+The integration can expose an `image` entity showing the Shield's current screen —
+`sensor`-free and **off by default**. Turn it on in **Configure → Main setup →
+"Add a screen capture image entity"**; the entity appears as
+`image.<entry>_screen_capture` on the existing device.
+
+Three things about it are deliberate, and they are the whole design:
+
+- **It never drives state.** An `image` entity's state is the timestamp of its last
+  successful capture. Nothing about a capture writes to the media player, the
+  sensors, the power switch or the manager's store — the capture path reads the ADB
+  poller and nothing else. Your media player keeps saying what the DEVICE reported,
+  not what a screenshot happened to show.
+- **It never polls.** HA sets `should_poll = False` for image entities and this one
+  keeps it: no scan interval, no timer. A capture happens only when something asks
+  for the bytes (the dashboard showing the entity picture) or when you call
+  `homeassistant.update_entity` on it. Back-to-back requests are coalesced into one
+  capture and a successful capture is reused for 5 seconds, so a dashboard repaint
+  cannot hammer the Shield.
+- **What it costs.** Every fresh capture is a full-resolution screen grab
+  (`screencap -p`) of the current display, base64-encoded, pulled over the same ADB
+  socket the state polling uses, and it keeps that socket busy for the duration. On
+  a 1080p UI that is typically a few hundred kilobytes of PNG (roughly a third more
+  on the wire because of the base64). Treat it as a diagnostic surface you look at
+  when something looks wrong, not as a camera.
+
+It is unavailable — never a blank image — whenever ADB is off, ADB is down, or the
+last capture failed; the `capture_status` attribute says which (`ok`,
+`adb_disabled`, `adb_disconnected`, `capture_failed`). An explicit
+`homeassistant.update_entity` retries after a failure.
+
+**How it captures, and why that matters.** The transport is `screencap -p |
+base64` over the existing shell, decoded locally with `base64.b64decode` and
+checked for the PNG signature and the `IHDR` chunk before anything is handed to HA.
+The alternative — writing a temp PNG on the device and pulling it as a file — needs
+the raw ADB device object and writes to the Shield's shared storage, where a crash
+between write and delete leaves a screenshot behind; the base64 route leaves no
+device-side artifact at all. The cost is the extra ~33% on the wire, and one thing
+is **inferred rather than measured**: no Shield was available in the development
+environment, so how the persistent socket copes with a few hundred kilobytes in one
+`shell()` call has not been observed on hardware. The decode, the failure paths and
+the entity contract are covered by tests, including a real-HA run that drives HA's
+own `ImageEntity` and content-type validator.

 ### The Apps table
 
-The **Apps** row is an editable table. One app per line, in the documented format:
+The **Apps** row opens a small editor rather than one long form. Home Assistant has no
+*table* selector, so a table is edited the way HA edits one — **one row per step**:
+
+| Row | What it does |
+| --- | --- |
+| **Edit the whole list as text** | the multiline field below: paste, rename or delete rows in one go |
+| **Add an app** | package id, name to show, and an optional icon |
+| **Edit an app** | pick one of the apps the Shield reported, or one you saved; its name and icon open prefilled |
+| **Remove an app** | pick a saved row, then confirm it on the next step |
+| **Back to the main menu** | leave the editor (nothing is written until **Save and close**) |
+
+*Edit* and *Remove* are offered only while there is something to act on: a table with
+no remembered rows and no discovery yet shows just the text field and *Add an app*. The
+editor's description lists every app it knows — the rows you saved, and the ones
+discovery found, marked `[detected]`. **Edit** acts on both (that is the point: an app
+the device does not name reads as `Your Name (package id)` when the map or the built-in
+app names know it, and as `package id (no name yet)` when nothing does — picking it is how
+you give it a name, and saving stores it as one of your own rows). **Remove** acts only on
+rows you saved, because a detected app has no line to delete (it would simply come back
+with the next sweep).
+
+A discovered app that nothing can name is **never pre-filled into the text field** as
+`package=package`: a row like that would store the package id as if it were a name. It is
+offered in the row editor instead, where "no name yet" says what it is.
+Removing a row never uninstalls anything from the Shield — the app simply stops being
+offered. Rows you do not touch are left exactly as they were.

+

+3. **the built-in app names** (see *Sources* below) — a curated, community-maintained
+   `package → name` table;
+4. **the package id**, shown **once** (never as `pkg=pkg` in a row).
+
+A label probe is cached for 24 h, and its outcome is remembered either way: a probe that
+**ran** and found nothing is a definitive negative (zero further round trips for that

+
+**Some devices expose no labels at all.** The reported Shield is one: nothing in that
+2241-line dump names any app. So after 5 probes in a row come back "ran, no label" the
+integration stops spending a shell per package for the rest of the 24 h TTL: the sweep

+### The remote entity: the app / activity picker
+
+The `remote` entity speaks Home Assistant's own remote contract, matching the
+`androidtv_remote` entity it replaces — so a replaced setup keeps its automations
+**and** gets the app picker the frontend only renders for a remote that declares it:
+
+| Piece | Value |
+| --- | --- |
+| `supported_features` | includes `RemoteEntityFeature.ACTIVITY` — without that flag Home Assistant offers **no activity picker at all**, which is why the remote card can look empty |
+| `activity_list` | the friendly app names, in your order: your **Apps table** (or the built-in table when you have none), plus the apps **ADB discovery** actually found on the device |
+| `current_activity` | the app on screen as a friendly name: the protocol's current-app push when it arrives, the ADB foreground reading otherwise. `None` while nothing is known — no activity is ever invented |
+| `turn_on` with `activity:` | wakes the Shield when it reports itself off, then launches that app over the protocol |
+
+```yaml
+# launch Netflix by the name from the activity list / Apps table
+action: remote.turn_on
+target:
+  entity_id: remote.living_room
+data:
+  activity: Netflix
+```
+
+An `activity` resolves in this order: a **name** from the activity list
+(case-insensitive), then a **package id** or a **detail link** (`https://…`,
+`market://…`) passed through unchanged — that is how an app your table does not carry
+is still launchable, and what the other integration does with a name it does not know.
+Anything else raises a clear error naming the value instead of silently doing nothing.
+Leaving `activity` out (or empty) keeps the old behaviour exactly: wake through the
+configured script, else `POWER` when the device reports it is off.
+
+**Where the list comes from, and why.** `androidtvremote2` exposes **no app-list API
+at all** (measured against the installed library) — which is exactly why
+`androidtv_remote` keeps a user-maintained app map. This integration has the same kind
+of source *plus* something the other one lacks: ADB discovery, so the picker can offer
+what is actually installed and name it through the one chain (your Apps table → the
+device's own label → the built-in table → the package id). Apps nothing can name are
+not listed as bare package ids; pass their id to `activity` if you need them.
+
+#### Is my protocol transport paired, connected, or not running at all?
+
+The library offers no `is_paired` / `is_connected`, so the remote entity publishes what
+can be **proven** (Developer Tools > States, or
+`state_attr('remote.living_room', 'protocol_state')`):
+
+| Attribute | Meaning |
+| --- | --- |
+| `protocol_state` | `off` (no transport configured), `never_connected`, `connected`, `disconnected`, or `auth_rejected` |
+| `protocol_connected` | `true` only while the device reports the protocol session up |
+| `protocol_ever_authenticated` | `true` once a session connected **or any push arrived** — the only proof of a paired client the library gives |
+| `protocol_current_app_seen` / `protocol_is_on_seen` / `protocol_volume_seen` | whether each device push has **ever** arrived (sticky: the state cache expires, these do not) |
+| `protocol_last_error` / `protocol_failures` | the last protocol connect/send failure verbatim, and how many sends could **not** run |
+| `protocol_certificate` | `present` / `missing` — the certificate from your setup pairing, which is why enabling the transport on a paired entry asks for **no new PIN** |
+| `power_on_route` / `power_off_route` | `protocol`, or `script:<script>` when a command script owns that command |
+| `activity_source` (and the media player's `app_source`) | which tier produced the app identity: `protocol` (the device's own push) or `adb` (the dumpsys parse) — the push is preferred, and it is never a silent override |
+
+Reading it:
+
+* **`auth_rejected`** — the device refused our certificate (a factory reset, or a
+  deleted `.storage/nvidia_shield/client.pem`). Home Assistant also flags the entry
+  for reauthentication; that flow re-pairs.
+* **`never_connected`** while the transport is enabled — switched on but with no
+  session. Pairing again is the answer (the options flow routes an unpaired entry
+  straight into the pairing step rather than enabling a client that cannot connect).
+* **`off`** — the transport is not configured. Everything else here still works: ADB
+  is the state source, so an ADB-only setup degrades **only** the protocol surface.
+* A send that could not run is **never silent**: it is counted, recorded verbatim in
+  `protocol_last_error`, and logged at WARNING together with `protocol_state`.
+
+**The other Android TV integration.** `androidtv_remote` pairs **its own client** and
+shares nothing with us: its certificate lives in its own storage and its entities are
+its own. Ours (`client.pem` under `.storage/nvidia_shield/`) is reused between pairing
+and runtime by design, so *not* being asked for a PIN on an already-paired entry is
+expected — and it says nothing about whether the session is up. `protocol_state`
+answers that.
+
+**A configured script bypasses the protocol.** When a command script owns `turn_on`
+(or `turn_off`), that script runs and the protocol is **never touched** — so a power
+press that worked through it is *not* evidence that the transport is paired, or even
+connected (`power_on_route` reads `script:…`). A configured **Remote command script**
+is the same story for `remote.send_command`. Only a command that went out over the
+protocol, with `protocol_state` = `connected`, exercises the transport.

+
+### Now-playing attributes
+
+**Since t65 the media player's now-playing reading is a set of separate
+TOP-LEVEL attributes**, not one nested object — that object read badly in YAML:
+
+| Attribute | What it holds |
+| --- | --- |
+| `now_playing_via` | which TIER produced the reading: `jellyfin`, `media_session` or `app` |
+| `now_playing_state` | the reading's own state — exactly one of `playing`, `paused`, `buffering`, `idle` |
+| `now_playing_title` | the title — or, in privacy mode, the app identity |
+| `now_playing_artist`, `now_playing_album` | the session's artist and album, when it has them |
+| `now_playing_media_type` | the content type the source reported |
+| `now_playing_series`, `now_playing_season`, `now_playing_episode` | series metadata, when the source reports it |
+| `now_playing_duration`, `now_playing_position`, `now_playing_position_updated_at` | playback timing |
+| `now_playing_thumbnail` | the artwork URL (or the Jellyfin entity picture) |
+| `now_playing_media_info` | the Jellyfin media-info dict, when that entity has one |
+
+The rules that keep the set predictable:
+
+- **Only what the tier answered is published.** An unknown field is OMITTED, never
+  `null`, so nothing ever reads as `now_playing_title: null`.
+- **A device that reads `off` publishes none of them.** A Jellyfin session that has
+  gone stale must not put a title beside a device that is off, and the state
+  already says nothing is playing. `on` (no source reported a power or playback
+  fact) publishes none either — there is no reading to publish.
+- **`now_playing_state` is one of FOUR values, and `on` is not one of them.** The
+  full set is `playing`, `paused`, `buffering`, `idle` — the states a source can
+  report when it has something to say. The row is published only while the entity
+  state is one of those four, so `on` (nothing reported), `off` and any frontend-
+  or app-side state can never appear beside a title. The list is code
+  (`NOW_PLAYING_STATE_VALUES` in `media_player.py`) and a test compares THIS
+  paragraph and the table above against it, so neither can drift.
+- **`now_playing_via` is deliberately not `source`.** On a media player, `source`
+  and `source_list` mean the selected app input (`Netflix`, `TiviMate`, …) and they
+  still do; naming the tier `source` is exactly what made the reading look like
+  media metadata from somewhere else. `media_dag_role` keeps its own separate
+  meaning (that this entity is the "source" role of the media graph).
+- **`now_playing_state` IS the entity's own state**, so a dashboard never reads two
+  different answers: the state ladder is the authority, and the foreground tier's
+  last-known-playback bridge can still publish a title while the state is already
+  `idle`.
+
+**Compatibility: `media_dag_now_playing` is GONE** — not deprecated, removed. It
+was one object; its contents are the attributes above. No alias is kept: a nested
+copy would double every poll's payload, and these attributes are declared
+*unrecorded* for exactly that reason (they must not bloat the recorder database). A
+template that read the object needs one rename:
+
+```jinja
+{# before #}
+{{ state_attr('media_player.shield', 'media_dag_now_playing').title }}
+{# after #}
+{{ state_attr('media_player.shield', 'now_playing_title') }}
+```
+
+The Jellyfin-backed `sensor.<entry>_now_playing` keeps its own flat set
+(`playback_state`, `title`, `media_type`, `series`, `season`, `episode`,
+`duration`, `position`, `thumbnail`), and it follows the same rule: a field the
+Jellyfin entity did not answer is omitted, so there are no `title: null` rows
+there either. Its `playback_state` reads `idle` whenever that session is not
+playing. `sensor.<entry>_current_app` publishes `app_id`/`app_name`, the same
+identity the media player carries beside its now-playing attributes.

+2. ``nonLocalizedLabel=Netflix`` — the ApplicationInfo field. It is usually
+   ``null`` on a TV device (the label comes from a resource), so a null/empty
+   value is not a name.
+3. ``labelRes=0x7f0f0001`` — a RESOURCE ID, not text. A dump can only name the

+   NOT used as a name: we would be showing ``0x7f0f0001`` as if it were a name.

+through to the curated map (the answer on a device with no labels at all).

+"""Intent discovery from an app's Activity Resolver Table (t16).
+
+The approved intents feature (``docs/INTENTS_PLAN.md`` §2) starts here: the user
+scans ONE installed app and we answer with the intents that app advertises. The
+source of truth is the ``Activity Resolver Table:`` section Android prints in
+``pm dump <package>``.
+
+WHY THE DUMP IS FILTERED ON THE DEVICE. On the user's Shield (captured
+2026-10-12) ``pm dump com.netflix.ninja`` is ~2241 lines of WHOLE dumpsys —
+``DUMP OF SERVICE package:`` and then activity/meminfo/procstats/usagestats/
+batterystats — for ONE app. Shipping that over ADB to read a few dozen resolver
+lines is the same mistake ``| head -300`` made for app labels (t66, where the
+truncation was misread as "this app has no label"), so the command built here
+pipes the dump through ``sed`` ON THE DEVICE and only the resolver section
+crosses the wire:
+
+    pm dump <pkg> 2>/dev/null \
+        | sed -n "/Activity Resolver Table/,/Service Resolver Table/p" \
+        | head -n <cap>
+
+with a bounded ``grep -A … -m 1 -F`` fallback (``intent_scan_fallback_command``)
+for a device whose toolbox cannot do sed ranges. The package id is always
+``shlex.quote``d — a package name is the only thing in either command that could
+carry shell metacharacters, and quoting it is what makes the command safe — and
+everything else in the command is a fixed constant from this file.
+
+WHAT THE CANDIDATES CARRY AND WHY. Per §3's data model: component, action,
+categories, and the data (scheme, authority, path). A filter that carries several
+schemes, authorities or paths is expanded into ONE CANDIDATE PER COMBINATION,
+because each of those is a concrete match — a URI the app really accepts — and a
+picker row that mixes two schemes cannot be turned into a URI at all. Candidates
+are deduplicated on the whole tuple, so the expansion costs nothing when the
+app's filters coincide.
+
+WHAT THIS MODULE DOES NOT MODEL: MIME types. The resolver key of a MIME filter
+(``video/*:``) is not one of §3's fields, and inventing a data URI out of it
+would be worse than reporting the filter through its component, action and
+categories — which is what happens. Nothing is dropped for being unmodelled.
+
+MARK — READ THIS BEFORE TRUSTING A SHAPE. The parser is proven against a
+TRANSCRIBED capture (``tests/fixtures/pm_dump_netflix_resolver.txt``), not
+against a device: no real Shield was available, and the raw capture text is not
+in this repository either. The entry/detail shapes below are what the capture
+records (see the fixture's own notes for which lines are verbatim and which are
+reconstructed), and every parser branch is deliberately tolerant of a shape we
+have never seen: an unrecognised line degrades to "no candidate from this line",
+never to a wrong candidate.
+
+NOT TO BE CONFUSED WITH ``.intent``: that module holds ``PlaybackIntent``, the
+optimistic-UI dataclass, not an Android intent. §7.4 of the plan suggests renaming
+it to ``playback_intent.py``; that churn is not part of this unit, so the two names
+sit side by side here and this note is the signpost.

+"""Screen-capture image entity — an OPT-IN diagnostic surface (t66).
+
+The user asked for "an image entity of the device screen capture? Can that be
+added". This is that entity, and it is the only thing in the integration that
+grabs the screen. Three boundaries are deliberate and load-bearing:
+
+* **It never drives state.** An image entity's state IS its
+  ``image_last_updated`` timestamp, and nothing here writes to the manager's
+  store, to the power ladder or to any other entity. A capture cannot make the
+  media player, the sensors or the power switch claim something the device did
+  not report. (The user's original constraint: screen capture must never drive
+  state.)
+* **It is opt-in, default OFF** (``CONF_SCREEN_CAPTURE_ENABLED``). With the
+  option absent ``async_setup_entry`` adds no entity at all.
+* **It never polls.** ``ImageEntity`` ships ``_attr_should_poll = False`` ("no
+  need to poll image entities") and this module keeps it. Nothing runs on a
+  timer; a capture happens only when something asks for the bytes (the image
+  proxy serving ``entity_picture``) or when the user calls
+  ``homeassistant.update_entity``.
+
+BINARY-SAFE CAPTURE — base64 over the shell, and why not a device file
+=====================================================================
+``AdbDevice.shell()`` returns ``str``: it decodes the shell channel as text, so
+raw PNG bytes cannot travel through it — ``\\x89PNG`` is not UTF-8 and the
+undecodable bytes would be mangled on the way out. There are two binary-safe
+routes and this module takes the SECOND:
+
+1. ``screencap -p /sdcard/<name>.png`` then ``AdbDevice.pull()`` — the library's
+   real binary path (the ADB sync protocol). It needs the raw ``AdbDevice``
+   object, which the ADB client owns as a private attribute, and it writes to
+   the device's shared storage: something must delete that file afterwards, and
+   a crash between write and delete leaves a full-resolution screenshot behind
+   on the user's device.
+2. ``screencap -p | base64`` then ``base64.b64decode`` locally. Base64 output is
+   pure ASCII, so the shell's text decoding cannot corrupt it, and there is no
+   device-side file at all — nothing to clean up, nothing to leak.
+
+Route 2 costs ~33% more bytes on the socket than route 1, and one claim is
+INFERRED rather than measured: no Shield was available here, so how the
+persistent ADB socket handles a few hundred kilobytes of base64 in one
+``shell()`` call is untested on hardware (the README says so). It is still the
+right trade: it uses the PUBLIC seam the watchdog's socket already offers
+(``manager.adb_poller.shell``), leaves no artifact on the device, and its
+correctness on the wire is provable here with a real PNG fixture.
+
+One capture costs exactly ONE shell, whatever the caller does: concurrent
+requests share a lock, and a successful capture is reused for
+``CAPTURE_REUSE_SECONDS`` so a dashboard repainting cannot hammer the device.

+# Intent catalogue and registered actions (plan)
+
+Scope: let the user discover the Android **intents** an installed app advertises, register
+the ones worth having, and fire them from Home Assistant — one button per registered
+intent, plus a `send_intent` action for the ones that need inputs.
+
+Status: design agreed in principle by the user (2026-10-12). Not built. Companion docs:
+`docs/MVP_PLAN.md` (architecture), `docs/RESEARCH_SHIELD.md` (device captures),
+`docs/RESEARCH_IDEAS.md` (adjacent ideas).
+
+**Decisions locked (user):**
+
+- Registered **buttons**, set up inside our options menu, plus a **`send_intent`** action.
+  Verbatim: *"The registered buttons, pre-setup within our menu options and a send_intent
+  command seem the best method here. Less messy than the current adb command method of
+  doing that."*
+- Discovery is **explicit** (the user scans an app), never an automatic sweep.
+- YAML stays **seed-only** (the standing ruling: we load it only when no UI config exists).
+
+---
+
+## 1. Where we are today
+
+| Surface | State |
+|---|---|
+| `media_player.play_media` with a URL | Works — sends a `VIEW` intent through the ADB path |
+| `nvidia_shield.adb_command` | Works but is a raw escape hatch, and until t14 cannot even be aimed at the Shield from the UI |
+| Intent **discovery** | Does not exist |
+| Intent **registration** | Does not exist |
+| `ha_adb_common/intent.py` | **Not Android intents** — it is `PlaybackIntent`, the optimistic-UI dataclass. The name collision is a readability trap worth fixing (§7.4) |
+
+So the user's memory of "scanning the available commands for ADB between applications" is
+a real gap, not something built and forgotten.
+
+### What the device actually exposes (observed, one Shield, Android 11)
+
+From the user's capture of `pm dump com.netflix.ninja` on 2026-10-12:
+
+- the output is ~**2241 lines** and is a *whole* dumpsys — `DUMP OF SERVICE package:`,
+  then `activity`, `meminfo`, `procstats`, `usagestats`, `batterystats`;
+- the package section begins with an **`Activity Resolver Table:`** listing, per
+  component/filter, the `Action:`, `Category:`, `Scheme:`, `Authority:` and `Path:` lines,
+  followed by `Receiver Resolver Table:` and `Service Resolver Table:`;
+- Netflix's table contains real, usable entries (`cast:`, `http`/`https` with
+  `www.netflix.com` path globs, `nflx:`, `netflix:`, `MAIN` + `LEANBACK_LAUNCHER`) and a
+  large amount of internal noise (`com.netflix.action.DEBUG_*`, `androidx.*`,
+  `com.google.firebase.*`, `ConstraintProxy*`).
+
+Everything in §2 depends on that shape. It is **observed on one firmware**, so the parser
+must degrade honestly rather than assume.
+
+---
+
+## 2. Discovery
+
+Source of truth: the app's **activity resolver table**.
+
+Filter **on the device** — on this Shield an unfiltered `pm dump` ships 2241 lines over
+ADB for one app:
+
+```sh
+pm dump <pkg> | sed -n '/Activity Resolver Table/,/Service Resolver Table/p'
+```
+
+with a bounded `grep -A` fallback when the device's `sed`/toolbox cannot do ranges. Keep
+the transfer to the resolver section; the rest of the dump is never needed.
+
+Rules:
+
+- **One package at a time, on demand**, triggered by the user from the Intents sub-screen.
+  Never a sweep of every installed app (that is 20 × ~2241 lines on this device).
+- **Cached** per package with a TTL, in the same spirit as the app-label cache; a scan
+  that *ran* and found nothing is a real answer, a scan whose transport failed is not
+  (the lesson from the discovery-cache defect).
+- **Rank, do not hide.** Flag internal-looking filters (`DEBUG_*`, `androidx.*`,
+  `com.google.firebase.*`) rather than deleting them — the user decides what is worth
+  registering, and we do not get to guess.
+
+A cheaper action-first query also exists (`cmd package query-activities --brief -a …`).
+**Not verified on this device**; treat as a possible optimisation, not the primary path.
+
+Candidates are deduplicated on (component, action, categories, scheme/authority/path).
+
+---
+
+## 3. Data model — a registered intent
+
+```yaml
+registered_intents:
+  - id: netflix_title            # slug; also the button's key
+    name: Netflix — open title   # what the user sees
+    package: com.netflix.ninja
+    activity: .MainActivity      # either a component…
+    action: android.intent.action.VIEW   # …or an action (+ categories)
+    categories: [android.intent.category.DEFAULT]
+    data: "https://www.netflix.com/watch/{id}"   # URI template, optional
+    fields:                      # declared inputs, with defaults
+      - {key: id, type: string, required: true}
+```
+
+Mapping to `am start` (through the existing ADB path):
+
+| Declared | `am start` |
+|---|---|
+| component | `-n com.netflix.ninja/.MainActivity` |
+| action | `-a android.intent.action.VIEW` |
+| categories | `-c …` (repeated) |
+| data template | `-d <resolved>` |
+| `type: string` | `--es key value` |
+| `type: int` | `--ei key value` |
+| `type: bool` | `--ez key value` |
+
+Notes that matter:
+
+- **No eval, no shell interpolation.** `{placeholder}` substitution is plain string
+  replacement, and every value is `shlex.quote`d before it reaches the device.
+- A missing **required** field is a `ServiceValidationError` naming the field.
+- An optional `raw` field type passes extras verbatim for advanced cases, documented as
+  **unvalidated** — the escape hatch, not the default.
+
+---
+
+## 4. Surfaces
+
+1. **One button entity per registered intent** — `button.<name>`, pressing it runs the
+   intent with the declared defaults. This is the "register an action for each one" the
+   user asked for, and it is the whole point for no-input intents.
+2. **`nvidia_shield.send_intent`** — `intent: <name>` (a dropdown of registered intents)
+   plus `variables: {…}` supplying that intent's declared fields. This is how per-intent
+   inputs arrive from automations, scripts and dashboards; it mirrors `script.turn_on`
+   with variables because HA offers no clean way to register a service per config entry.
+   The action **returns the device's `am start` output**, so a failure is visible.
+3. **Intents sub-screen** in the options flow, the same idiom as the Apps screen:
+   *Add an intent* (pick package → pick a discovered candidate or enter one manually →
+   name it → declare its fields), *Edit*, *Remove*, *Scan an app's intents*.
+4. **YAML seeding** — a `registered_intents:` block, honoured only when the UI holds
+   nothing (seed-only ruling).
+
+---
+
+## 5. Failure modes and honesty
+
+- `am start` failures (unresolved intent, permission denied, activity gone after an app
+  update) **surface the device's own message** and raise; never a silent success.
+- **ADB is required.** The protocol transport cannot send intents; when ADB is down the
+  error says so instead of failing obscurely.
+- An unknown intent name raises, listing the known names.
+- An intent that the app rejects is a **config** problem, and the docs say so plainly.
+- Nothing registered ever runs by itself, and discovery never auto-registers anything.
+
+---
+
+## 6. Costs
+
+- Discovery: one filtered dump per scanned package, cached.
+- Invocation: one ADB shell per press.
+- Storage: registered intents are ordinary options data.
+
+---
+
+## 7. Open questions
+
+1. Does `send_intent` returning a response need `SupportsResponse.OPTIONAL` on our HA
+   floor? Verify against the real installed HA before building on it.
+2. Typed fields (string/int/bool) for v1, or string-plus-raw only? Recommendation: typed,
+   since that is what makes the dropdown-plus-variables model pleasant.
+3. Broadcasts/receivers (`am broadcast`) — the tables are right there — are **out of scope
+   for v1**; activities and actions only.
+4. Rename `ha_adb_common/intent.py` → `playback_intent.py` so the new `intents.py` is not
+   confused with it? Small churn, real clarity gain.
+5. Should discovery be exposed as a service as well as a UI screen? Recommendation: UI
+   only in v1.
+6. `play_media(media_content_type="intent")`? Recommendation: **no** — the button and the
+   action are clearer, and play_media already carries the URL/VIEW case.
+
+---
+
+## 8. Proposed tickets
+
+| Unit | Contents |
+|---|---|
+| Discovery | `ha_adb_common/intents.py` + the filtered on-device dump + parser + cache + tests, with a fixture cut from the user's real Netflix capture |
+| Registration & invocation | Intents sub-screen, per-intent fields, button entities, `send_intent` action, mapping, docs, strings, tests |
+| Review | Adversarial verification of both, including a rejected-intent and an ADB-down path |
+
+---
+
+## 9. Non-goals
+
+- No automatic intent execution or auto-registration from discovery.
+- No arbitrary shell passthrough in `send_intent` (`adb_command` remains that door).
+- No broadcasts/receivers in v1.
+- No extras beyond string/int/bool/raw.
+- Not a replacement for the app source list or `play_media`.

+#: 77 imports, 282 relative imports, 65 checked arguments, 6 awaited HA calls,
+#: 1661 statement blocks) so a broken or mis-targeted walk fails loudly instead of
 #: printing zeros and exiting 0.
+#:
+#: THE MARGIN POLICY (t20/O3 — the t19 review asked for this in writing). A floor
+#: is a VACUITY-AND-BLINDNESS alarm, not a size ratchet: it must fail when the walk
+#: stops COVERING something (a broken glob, a regex that stopped matching, a module
+#: that stopped being parsed), and it must not fail because a legitimate change
+#: removed code. The margins follow from that, per counter:
+#:
+#:   * counters where ONE unit is one API OWNER (modules, imports, call_args): 2.
+#:     One owner may be refactored away; a whole CLASS of owners going unseen (the
+#:     t62 F2 case, where deleting `async_show_menu` from HA_CALL_OWNERS left the
+#:     sweep green) is what the 2 catches. This is the project's long-standing
+#:     canary (t62 wrote it as "two below the count"), now stated once instead of
+#:     being implied by each raise.
+#:   * relative_imports: ~2.5%. The count is dominated by package-relative imports
+#:     that legitimately churn when files move; a collapse (an unparsed module, a
+#:     stale glob) is orders of magnitude, not a handful.
+#:   * statement_blocks: ~2%. This counter moves in BULK with every edit, which is
+#:     exactly why a fixed small margin would be wrong here (the t19 complaint: at
+#:     1300 vs 1322 a 23-statement refactor tripped it). A 2% band leaves a normal
+#:     refactor alone while a parse failure still shows up as a large drop.
+#:
+#: No band states a COUNT: the current walk is in the header above and printed by
+#: every sweep run, so a figure in this prose can only rot — a previous revision
+#: carried exactly such a figure for statement_blocks and it was stale within one
+#: unit of work (t24/O3). The BANDS are the policy and are deliberately the only
+#: numbers here; a floor, once re-derived from a re-measured walk, is named next to
+#: the counter that owns it.
+#:   * awaited_calls: 1 (measured 6, floor 5 — DELIBERATE, see below). Stated
+#:     plainly: with six awaited HA calls a percentage margin is meaningless, so
+#:     this floor is the weakest one here. It is still worth having — a walk that
+#:     stopped visiting `await` sites at all trips it — but a deliberate removal of
+#:     an awaited call MUST lower this floor in the same commit, and that is the
+#:     reviewable act the gate exists for.
+#:
+#: t18/F3 asked whether these margins are deliberate and whether the counters were
+#: genuinely updated rather than dodged. Both answers are yes, and they are recorded
+#: HERE rather than in a task log: the t18 review measured awaited_calls at 6
+#: against this floor of 5 and three other counters within 2 (modules 26/24,
+#: imports 77/75, call_args 65/63 — each named in its own comment below), and the
+#: verdict is that those ARE the policy margins above: 2 for owner-counters because
+#: an owner really can be refactored away, 1 for awaited_calls because the counter
+#: is too small to do better. The counters themselves were RAISED to the real sweep
+#: when the code grew (20→24, 70→75, 235→275, 55→63, 1400→1620) and re-derived
+#: twice since (t20: 1620→1615; t21: 1615→1617 after this unit's blocks), never
+#: lowered to dodge a failure and never left above the walk.
+#:
+#: The rule for changing any of them: lower a floor in the SAME commit that removes
+#: the code it counts, and never raise one without re-running the sweep first (a
+#: floor above the walk is a gate that can never pass).

+"""t14: `nvidia_shield.adb_command` against a REAL Home Assistant install.
+
+The user's report was that the Shield could not be SELECTED for the action, so he
+ran his diagnostics through the deprecated ``androidtv`` integration. A stub suite
+cannot settle that: the picker is whatever HA hands the browser, and "was the
+command sent to the Shield I picked?" is decided by HA's own service registry,
+schema validation and target merging.
+
+What this file drives, on the installed HA (2026.10.1):
+
+* the REAL ``hass.services`` registry — the registration our ``async_setup`` makes;
+* the REAL websocket command the frontend calls (``get_services``), asserting the
+  payload carries ``target: {entity: [{domain: media_player}]}`` — that payload IS
+  the picker;
+* the REAL ``hass.services.async_call`` with ``return_response=True`` — asserting
+  the output comes back under ``adb_response`` (the key the user's captures use)
+  and that a call without it behaves as before;
+* the REAL entity registry, for the ``device_id`` shape an automation sends.
+
+WHAT THIS FILE CANNOT PROVE: there is no browser here, so nothing about how the
+picker LOOKS. It proves the wire contract — the registration, the metadata the UI
+consumes, and the resolved call. Every test skips cleanly when homeassistant is not
+installed (run it with ``--with 'homeassistant>=2026.10' --with adb-shell``).

+device side is a scripted double that would answer everything: no real Shield is
+involved, so what is proven is that nothing was sent, not what firmware would do.
+
+WHAT "NOTHING IS CACHED" MEANS EXACTLY (t24/O4): the ONE write a disabled path can
+still make is a retry DEBT — ``_app_label_failed.add(package)`` in ``_dump_label``
+— and a debt is not an answer: the label cache (``_app_labels``) stays untouched,
+``app_label`` keeps returning None, and the debt is settled the moment the probe
+finally runs with ADB back on. Asserted in
+``test_the_only_write_while_off_is_a_retry_debt_not_an_answer``.
+
+WHAT THIS FILE DOES NOT GATE (t25/O1): the paths where "ADB off must mean no
+traffic" is deliberately NOT enforced, each listed in :data:`CARVE_OUTS` with its
+mitigation and with the test that asserts that mitigation — the Pair ADB button's
+press and ``ShieldConnectionManager.test_connect``. Naming them is the point: an
+audit that silently excludes a path is not an audit, and a carve-out whose
+assertion does not exist is prose.

+
+THE OBSERVATION THIS CLOSES. The batch review read `extra_state_attributes` and
+argued the now-playing row publishes "the entity state verbatim", so a dashboard
+could see `now_playing_state: on`, while the README documents only `playing`,
+`paused`, `buffering` and `idle`. t10's author had reported the opposite (an
+`on` or `off` device publishes no row at all). Both accounts were about a
+different thing, and this file settles it BY EXECUTION:
+
+* the t10 account is true for the NATURAL ladder — `on` means no source reported
+  a power or playback fact, and a reading only exists when a tier answered, so
+  the two cannot meet in practice;
+* the review was right about the RULE, which was "publish unless the state is
+  `off`" — an unenforced assumption, and the probe below shows it publishing
+  `now_playing_state: on` (and `standby`) the moment a reading exists beside that
+  state. `standby` is not even in the README, and nothing in the code stopped it.
+
+WHAT WAS CHANGED. The publication rule now names the four values a reading may
+carry (`NOW_PLAYING_STATE_VALUES`) and drops the reading when the entity state is
+anything else, exactly as a state of `off` always did. The README says the same
+thing in words. The two tests here walk EVERY ``MediaPlayerState`` member and

+"""t17: `nvidia_shield.send_intent` against a REAL Home Assistant install.
+
+The intents feature has one claim a stub cannot settle: that the action RETURNS
+the device's output, and that the frontend is offered the registered intents as a
+dropdown. Both are decided by Home Assistant itself — the response flag comes from
+``async_set_service_schema`` reading ``hass.services.supports_response()``, and the
+dropdown is whatever description the websocket command serves — so this file
+drives the installed HA (2026.10.1) end to end:
+
+* the REAL service registry: the registration ``async_setup`` makes, its schema,
+  and ``SupportsResponse.OPTIONAL`` (a *required* response would break every
+  caller that does not ask for one);
+* the REAL ``get_services`` payload — the exact JSON the frontend parses — so the
+  intent dropdown and the entity target picker are proven where they are consumed;
+* the REAL ``hass.services.async_call`` with ``return_response=True``: the output
+  comes back under ``intent_response``, and the command that reached the fake ADB
+  surface is asserted verbatim;
+* the REAL exception machinery: an unknown intent, a refused intent and ADB being
+  down each raise ``ServiceValidationError`` with our translation key and a usable
+  message (never a silent success, never an empty response).
+
+WHAT THIS FILE CANNOT PROVE: there is no Shield and no browser here. The command
+string is asserted against the fake poller (the real ADB transport is t13/t14's
+subject), and "how the dropdown LOOKS" is the frontend's business — the wire
+contract is what this file pins. Every test skips cleanly when homeassistant is
+not installed (run it with ``--with 'homeassistant>=2026.10' --with adb-shell``).
