Edits previously never reached the MP4 (the node rendered template defaults). Now:
- render-svc claim includes the saved input values as bindings (GetRenderBindings →
saved_scene_contents with non-empty value).
- node-agent: new binder.go emits a JSON bind-spec + downloads media locally, runs the
pre-existing data-driven bind.jsx via afterfx (sets text layers' Source Text, replaces
media footage), saves a bound.aep next to the template, then aerender renders THAT.
- 12-min timeout + fresh-AE + done-marker polling (mirrors scan). Non-fatal: on bind
failure the job still renders template defaults.
Verified binding data flows (edited frl_c1t1/frl_c1t2 → claim bindings). Live MP4
verification needs the updated node-agent.exe re-run.

THE bug behind "AEPFilePath is required for real AE render": CreateJob inserted
original_project_id = saved_project_id (VALUES $3,$3), so the claim looked for the
render bundle at templates/{saved_project_id}/ — which never exists. The bundle
lives at templates/{TEMPLATE_id}/. Now original_project_id is resolved from
studio.saved_projects.original_project_id (the template the project was built from).
(Direct-SQL test renders masked this by setting the template id explicitly.)
Also harden the node-agent: Run() falls back to mock render when AEPFilePath is
empty even if AE is installed (previously hard-errored), so a missing/un-promoted
template degrades gracefully instead of failing the job.

aerender can't reliably write H.264 directly in modern AE — it renders the
project's output module (Lossless AVI/MOV) and ignores the .mp4 extension,
producing a multi-GB .avi the agent then failed to find/upload.
- findRenderedOutput(): locate the file aerender actually wrote (output.avi/.mov/.mp4)
- transcodeToMP4(): ffmpeg → H.264 yuv420p + AAC + faststart; drops the lossless
intermediate. ffmpeg located via $FFMPEG_PATH, beside the agent exe, or PATH.
- Graceful fallback: if ffmpeg is missing/fails, upload the raw render so the job
still delivers a (large but valid) file.

Three bugs surfaced bringing up a real After Effects node (verified: AE 2026
claimed + ran, but produced no usable output):
1. aerender got no -comp/-rqindex → "output argument ignored", nothing rendered.
- Claim now returns comp_name from content.projects.render_aep_comp (e.g. "frfinal")
via new Store.GetTemplateCompName; threaded through ClaimedJob → runner.Job →
aerender args (`-comp <name>`, or `-rqindex 1` fallback when unknown).
2. CreateExportForJob INSERT passed render_quality as a bare param into an enum
column → 500 ("output-upload-url HTTP 500"), so completed renders had no export.
- Cast $8::render.render_quality (+ explicit casts for file_type/create_type enums).
3. flatrender-exports bucket didn't exist → uploads would fail anyway.
- render-svc now MakeBucket(exports, templates) idempotently at startup.

render-svc:
- db.UpdateJobPreview(): writes base64 PNG to render_jobs.image_preview_b64
(only on active jobs; Done/Failed/Cancelled rows ignored)
- POST /v1/internal/render/jobs/:job_id/preview — node agent endpoint
- Route registered under /v1/internal (nodeAuth)
node-agent:
- runner.PreviewFn callback type alongside ProgressFn
- runner.preview.go: GeneratePreviewB64(percent, quality, resolution)
— pure stdlib (image/png + encoding/base64), no external deps
— 320×180 dark frame with animated progress bar + colored indicator dots
- mock render: pushes a preview frame at every step (5→95%)
- real AE render: pushes a preview frame every 30s
- client.UpdatePreview(): POST /v1/internal/render/jobs/:job_id/preview
- main.go: onPreview callback wires client.UpdatePreview() into runner.Run()
frontend:
- render-jobs.ts: RenderJobRow.preview_b64 field; read from progress endpoint
- status/route.ts: previewB64 included in JSON response
- RenderModal: aspect-ratio preview pane during polling — shows spinner until
first frame arrives, then live-updates with each poll (every 3s);
