docs: HA Google Home config deployed + verified (correct entity id)

Deployed script.print_daily_briefing (scripts.yaml) and exposed it in
google_assistant.entity_config on VM HA .146; ha core check passed, restarted,
request_sync OK. Verified end-to-end: HA script -> MQTT -> bridge -> printed.
Corrects the button entity id to button.pos_briefing_print_daily_briefing.

-# HA + Google Home setup — POS Briefing button
+# HA + Google Home setup — POS Briefing button (DEPLOYED 2026-06-07)
 
-The MQTT bridge (`pos-briefing-mqtt.service` on steel141) auto-creates an HA
-button via MQTT discovery. Google's `google_assistant` integration does not
-support `button` entities, so we wrap the button in a `script` (scripts expose to
-Google as a **Scene** = a tappable button in the Home app).
+Status: **deployed and verified end-to-end** on VM HA (`192.168.0.146`, HAOS 2026.2.3),
+except the final Google-app tap (yours to try).
 
-Chain: **Google Home tap → HA script → `button.press` → MQTT `posbriefing/button/press`
-→ bridge runs `pos_briefing.py` → prints on the TM-m30.**
+Chain: **Google Home tap → HA `script.print_daily_briefing` → `button.press` →
+MQTT `posbriefing/button/press` (broker CT 301) → `pos-briefing-mqtt.service` on
+steel141 → `pos_briefing.py` → printer (by MAC) → TM-m30.**
 
-## 0. Confirm the entity exists
-Settings → Devices & Services → **MQTT** → device **POS Briefing**. You should see
-button **Print Daily Briefing** (entity `button.print_daily_briefing`). Pressing it
-in HA should print a receipt. (Status is published on `posbriefing/status`:
-`idle`/`printing`/`ok`/`error:<msg>`; availability on `posbriefing/availability`.)
+Google's `google_assistant` integration doesn't support `button` entities, so the
+MQTT-discovery button is wrapped in a `script`, which Google exposes as a **Scene**
+(a tappable button in the Home app).
 
-If the entity id differs, use whatever HA shows in the script below.
+## What was deployed (VM HA `/config`, backed up to `/config/.backup/`)
 
-## 1. Add the script
-Settings → Automations & Scenes → **Scripts** → (top-right) Edit in YAML, or paste
-into `scripts.yaml`:
-```yaml
-print_daily_briefing:
+1. **`scripts.yaml`** — the script (note the real discovery entity id, which HA
+   prefixed with the device name):
+   ```yaml
+   print_daily_briefing:
      alias: Print Daily Briefing
      sequence:
-    - service: button.press
+       - action: button.press
          target:
-        entity_id: button.print_daily_briefing
+           entity_id: button.pos_briefing_print_daily_briefing
      mode: single
-```
-
-## 2. Expose the script to Google
-Add to the SAME `google_assistant:` block that already exposes the LG TV switch
-(keep your existing `project_id` / `service_account` lines):
-```yaml
-google_assistant:
-  project_id: <your existing project_id>
-  service_account: !include <your existing service_account file>
-  report_state: true
-  exposed_domains:
-    - switch
+   ```
+2. **`configuration.yaml`** — `script.print_daily_briefing` added to the existing
+   `google_assistant.entity_config` (alongside the LG TV + projector; nothing else
+   touched):
+   ```yaml
+   google_assistant:
+     # ...existing project_id / service_account / report_state / expose_by_default...
      entity_config:
        script.print_daily_briefing:
          name: Print Daily Briefing
          expose: true
-```
-Reload (Developer Tools → YAML → "Google Assistant" or restart HA).
+       # switch.big_tv_lg_tv ... media_player.mitsubishi_projector ... (unchanged)
+   ```
+3. `ha core check` passed → `ha core restart` → `google_assistant.request_sync` (HTTP 200).
 
-Reminders from the lgtv 2026-06-06 linking (already satisfied for your setup):
-manual `google_assistant` integration (not Nabu Casa); account-linking scopes must
-include `email` + `name`; the **"HTTP basic auth header" checkbox must be OFF**; the
-Google **Test** must be activated by the same account used in the Home app
-(slingshooter08). The GCP OAuth consent screen is unrelated to smart-home linking —
-don't touch it.
+## Verified
+- `script.print_daily_briefing` loaded in HA (state `off`, "Print Daily Briefing").
+- Firing the script via HA API → bridge logged `Received: PRESS` → `Running briefing...`
+  → `Briefing printed OK` → **physical receipt printed**.
+- MQTT discovery button is `button.pos_briefing_print_daily_briefing` (Settings →
+  Devices → MQTT → **POS Briefing**).
 
-## 3. Sync to Google Home
-Say "Hey Google, sync my devices" (or re-run device setup in the Home app). The
-button appears as **Print Daily Briefing**; tapping it prints the receipt.
+## Your only remaining step
+Open the Google Home app (account `slingshooter08`). **Print Daily Briefing** should
+appear as a control (after the request_sync; if not, say "Hey Google, sync my
+devices"). Tap it → receipt prints. Optionally assign it a room / rename.
 
-## Optional: surface print status in HA
-Add an MQTT sensor (configuration.yaml) if you want to see the last result:
-```yaml
-mqtt:
+## Notes
+- A print takes ~1–2 min (gemma4:26b summarization). The button/scene returns
+  immediately; `posbriefing/status` goes `printing` → `ok`. A second press while one
+  is in flight is ignored (debounced) — no double prints.
+- Google-linking invariants (from lgtv 2026-06-06, already satisfied — don't re-fix):
+  manual `google_assistant` integration; account-linking scopes include `email`+`name`;
+  "HTTP basic auth header" checkbox OFF; the GCP OAuth consent screen is unrelated.
+- Optional MQTT status sensor (configuration.yaml) if you want last-result visibility:
+  ```yaml
+  mqtt:
     sensor:
       - name: "POS Briefing Status"
         state_topic: "posbriefing/status"
         availability_topic: "posbriefing/availability"
-```

-## Notes
-- A print takes ~1–2 min (gemma4:26b summarization). The button returns immediately;
-  watch `posbriefing/status` go `printing` → `ok`.
-- A second press while one is in flight is ignored (debounced) — no double prints.
