The full renderMd() pipeline maps MEDIA:<path-or-url> tokens to inline
images / video / audio / SVG / PDF / etc. via stash + restore passes.
The streaming smd renderer used by the live assistant body never went
through that pass, so any MEDIA token emitted mid-turn showed up as the
raw path string in the chat window and only became a real <img> once
the turn settled and the full render fired.
Fix:
- Extract the URL/media → HTML mapping in renderMd() into a shared
helper _inlineMediaHtmlForRef(ref, sessionId) so the streaming path
can reuse the same DOM the settled message will eventually render.
- Add _smdMediaAwareAddText in messages.js that wraps smd's add_text
to detect MEDIA tokens in any incoming text chunk and splice the
resulting <img>/<video>/<a>/<div data-path=...> node directly into
the smd parent via a DOMParser-created fragment. Plain prose still
delegates to the renderer it intercepted (so the fade renderer keeps
its word-by-word animation, the safe renderer keeps its O(n) plain
text-node insertion).
- Route _safeSmdRenderer.add_text and _streamFadeRenderer.add_text
through the interceptor. Each fast-paths the no-MEDIA case to the
original baseAddText so we can't recurse into our own wrapper.
Coverage:
- New test_smd_media_in_stream.py locks in the architectural invariants
(helper exists, both renderers delegate to it, recursion guard).
- test_renderer_js_behaviour.py driver now provides a minimal
_inlineMediaHtmlForRef stand-in so renderMd can be invoked standalone
under node without the rest of ui.js in scope (matches the patterns
renderMd already relied on for _IMAGE_EXTS / _SVG_EXTS / _AUDIO_EXTS).
- test_svg_audio_video_rendering.py static-count assertions relax from
">=2" to ">=1" since audio/video/SVG markup now lives in a single
shared function rather than being copy-pasted inside renderMd's
stash-restore closure.
