 ## ⏭️ NEXT UP — Studio↔Template binding EPIC (agreed priority)
 
-**Start with Phase B: edit→render binding.** Full plan in `~/.claude` memory
-`epic_studio_template_binding.md`. Summary:
-- **B1** persist studio input edits to `saved_scene_contents` (new studio-svc
-  `PATCH /v1/saved-projects/{id}/contents` by content key) — today edits only go to `edit_state`.
-- **B2** render binder (port v1 `JSXGenerator.cs`): before aerender, JSX sets each AE layer
-  (named `frl_c{n}{t|m}{i}`) text/footage + frshare colours from the saved values, then render.
-  Today the node renders the template with DEFAULT values → user edits never reach the MP4.
-- Then **A** admin preset stories (premade videos — model `preset_stories`/`preset_scenes`
+**Phase B DONE (commits a69bc62 B1, 47a4ced B2).** Edit→render binding works:
+- **B1 ✅** studio input edits persist to `saved_scene_contents` via studio-svc
+  `PATCH /v1/saved-projects/{id}/contents` (Next `/api/projects/[id]/contents`); the
+  persistence hook pushes edited values (bridged `c-<key>` layers) on every save.
+- **B2 ✅** render-svc claim now includes `bindings` (GetRenderBindings = saved_scene_contents
+  with non-empty value); node-agent `binder.go` emits a JSON bind-spec + downloads media, runs
+  the data-driven `bind.jsx` via afterfx (sets Source Text, replaces footage) → saves `bound.aep`
+  → aerender renders THAT.
+- **VERIFY (needs node-agent re-run):** re-run the updated `node-agent.exe`, edit a text input in
+  the studio (wait for "saved"), render, confirm the MP4 shows the edited text. Colours
+  (saved_shared_colors → spec.colors) + footage-item media (vs layer-source) are follow-ups.
+
+- Next: **A** admin preset stories (premade videos — model `preset_stories`/`preset_scenes`
   exists, no endpoints/UI; detail "ویدیوهای ساخته‌شده" is placeholder), and **C** AE single-frame
   scene snapshots (`scenes.snapshot_url` empty → node `aerender -s 0 -e 0`).
