* feat(box): bidirectional attachment transfer for sandbox Materialize inbound attachments into the sandbox workspace so agents can process user-sent files, and collect agent-produced files from the outbox to attach them back to the reply. - box(service): add materialize_inbound_attachments / collect_outbound attachments. Prefer direct host-filesystem read/write on the bind-mounted workspace (no size limit), falling back to chunked exec only for non-shared backends (e2b/remote). Clear per-query inbox/outbox dirs at turn start to avoid query_id-reuse collisions. - provider(localagent): inject inbound attachment descriptors into the sandbox and append a system note telling the agent the inbox/outbox paths. - pipeline(wrapper): collect outbox files on the final stream chunk and append them as attachment components to the response chain. - web(debug-dialog): render File components with a download link when base64/url is present; add base64/path fields to the File entity. - tests: cover inbound/outbound, large-file transfer without truncation, and stale-dir clearing (86 passing). * feat(box): support voice/file attachment round-trip end-to-end Extends the bidirectional attachment transfer to audio and arbitrary files through the real webchat UI, and fixes the model-payload errors that non-image attachments triggered. - platform(websocket_adapter): resolve Voice/File component storage keys to base64 (previously only Image), so audio/documents reach the sandbox inbox. - web(debug-dialog): accept audio/* and any file in the uploader (was image-only), classify by mimetype, upload Voice/File via the documents endpoint, and render non-image staged attachments as a chip. - provider(litellmchat): drop non-image file parts (file_base64 / file_url) when building the OpenAI/LiteLLM payload. These come from Voice/File attachments — including ones replayed from conversation history — and the agent reads their bytes from the sandbox, not the model. Without this the provider rejects the request: 'invalid content type=file_base64'. - provider(localagent): also strip those parts from the current user message alongside the sandbox-path note (model-facing clarity; the requester is the real safety net for history). - tests: cover the requester strip/keep behavior (file dropped, image kept and reshaped to image_url, mixed history, plain-string content). * test(box): cover inbound/outbound attachment helpers; fix ruff format - ruff format localagent.py (CI ruff format --check was failing) - add unit tests for ResponseWrapper outbound-attachment helpers (wrapper.py 78%->98%) - add unit tests for LocalAgentRunner._inject_inbound_attachments - add unit tests for WebSocketAdapter._process_image_components (0%->covered) Lifts PR patch coverage from 68.97% to ~88% (>75% target).
