wave 1 (platform stream): background-observability accuracy + owner-driven follow-ups
- observability: liveness-gated stale-job recovery, extraction run registry on globalThis with
explicit 'embedding' phase, /api/jobs force-dynamic, client refresh nudges at every seam
- headless: providerSafePng canonicalizer (multi-IDAT Chrome PNGs → single-IDAT) fixing qwen 400s
- composer: Enter routes through pure enterAction — accepts a pending plan verdict (owner decision)
- markdown chrome: session-scoped mermaid overlay + md-blocks component set + pan-zoom math,
corner-copy (clipboard grant in electron main), math/table/code block fixes, heading weight 900
