Read & Translate Sign

OCR text from the current view, then (if a target language is implied or asked) translate it, surfacing both on a translator panel in sign mode.

Steps

1. Pick the path:
   • Read only ("what does this say?") → read_text → shows a panel.
   • Read + translate ("translate this sign") → translate_view (does OCR + translation in one call) → shows a translator.
   • Translate provided text (not from camera) → translate_text.
2. Determine target language. Default to the session locale from client.hello; honor explicit "…into French".
3. Call the tool. translate_view returns data.source_text, data.translated, data.target_lang, an observation, and a translator directive.
4. Narrate with agent.observation/agent.speech and render the panel.

Output

agent.observation:

{ "text": "The sign reads: 非常口. In English: Emergency Exit.", "final": true, "annotations": [] }

translator hologram (show_translator, props per registry.json):

{ "widget_type": "translator",
  "transform": { "anchor": "head", "position": [0.0,0.0,1.0], "billboard": true },
  "props": { "source_lang": "auto", "target_lang": "en",
             "source_text": "非常口", "translated_text": "Emergency Exit", "mode": "sign" },
  "interactions": ["tap","grab","resize" 

Read-only path uses a panel:

{ "widget_type": "panel", "props": { "title": "Read", "body": "Gate B12 — Boarding 14:05" } }

Edge cases

• No legible text → "I can't make out any text from here — move a little closer or steady the view." Spawn nothing.
• Mixed languages / long passages → translate the dominant language; for long documents suggest document_viewer instead of a translator panel.
• Live two-way conversation (not a static sign) → hand to communication-agent's live-translate.
• Source == target language → skip translation, just read it back.
• Numbers/codes (gate, room, price) → preserve verbatim; don't "translate" digits.
• Privacy → if you warmed the camera with perception.request{action:"once"}, stop it when done.
