RCOM + ContextSync Unified Daemon (prototype)

One local daemon that speaks two interfaces simultaneously:

• FUSE mount — apps and humans see a normal filesystem
• ContextSync HTTP + SSE — peer daemons and external clients speak the v0.3 protocol

Over one unified store — same blobs, same version DAG, same permission table, same provenance log.

Design drafts

• Protocol addition (typed edges as 6th primitive): ../drafts/spec_edges_addition.md
• Revised architecture section (unified daemon): ../drafts/newprd_section2_revised.md

Status

Scaffold. Only /health and the /artifacts create/read path are wired. Everything else is stubbed to return 501 Not Implemented.

Next milestone: two daemons, one file written via FUSE on A appears under FUSE mount on B via SSE.

Run
