soroush.asadi	d7743a6fbe	feat: live render preview — node agent pushes PNG frames, frontend displays them in real time ... 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); step label overlaid as badge bottom-right Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-06-01 09:42:03 +03:30
soroush.asadi	ee421ccc68	feat(render-svc+node-agent): add job-claim endpoint and build node-agent skeleton ... render-svc: - db: ClaimJob() — atomic SELECT FOR UPDATE SKIP LOCKED; transitions job to Preparing, marks node Busy in a single transaction - models: ClaimJobRequest + ClaimedJob types - handlers/internal: POST /v1/internal/render/jobs/claim — 200 with job or 204 when queue empty - main: register the claim route under /v1/internal (nodeAuth) services/node-agent/ (new Go module github.com/flatrender/node-agent): - internal/config: env-var based config (NODE_ID required, sensible defaults) - internal/client: typed orchestrator HTTP client (Online, Heartbeat, ClaimJob, Complete, Fail, ReportCrash) — X-Node-Signature auth - internal/runner: AE render via aerender.exe or mock (for dev without AE) - cmd/agent/main: register online → heartbeat loop (5s) + poll loop (3s) → claim job → run render → report complete/fail; health endpoint on :7777 - Dockerfile: cross-compiles to Windows amd64 static binary Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-06-01 09:28:31 +03:30
