From an independent review of the branch:
- Regression: existing non-raster-but-showable visuals (.svg diagrams) were
dropped by the renderable filter — they were served fine before via <img>
(/thumb passes SVG through). Add .svg to MEDIA_IMAGE_EXT.
- Doc accuracy: the board dedupes decisions by (category, subject), not category
alone (category-only would wrongly merge distinct decisions that share a
category, e.g. TTS vs image provider_selection). Correct AGENT_GUIDE to say
the pair is the key and to reuse the same subject when re-logging.
- Coverage: the new visual-selection logic was untested (which let the earlier
missing-file regression through). Add TestStoryboardVisualSelection covering
the .tsx-animation exclusion, snapshot fallback (exact + <id>_* match), SVG
renderability, the preserved missing-file indicator, and takes = renderable.
Not changed (reviewed, deliberate): .narr clamp at --fs-scale 1.16 degrades
gracefully via the fade + click-to-expand modal; decision dedupe stays keyed on
(category, subject) as the more-correct behavior.
