Topology

epiphany-brief is a 17-node, 23-edge graph with topology class gated fan-out with interview loop.

Node overview

The graph flows through these stages:

  1. N-CAPTURE --- reads the input, extracts ACUs (Atomic Content Units).
  2. N-CLASSIFY --- classifies the domain and input type.
  3. N-EXPLORE nodes --- fan-out explorer nodes (multiple, parallel) that analyze the content from different angles.
  4. N-AND-JOIN --- AND-join that waits for all explorers.
  5. N-ISSUE-EXTRACT --- identifies gaps, ambiguities, contradictions.
  6. N-INTERVIEW --- HITL interview loop (one question per turn, exit-11 pause).
  7. N-STRUCTURE --- structures content into brief sections.
  8. N-DRAFT --- assembles the living-brief document.
  9. N-VERIFY-CLAIMS --- verifies technical claims against sources.
  10. N-COVERAGE --- zero-loss coverage gate (set-difference ACU check).
  11. N-REVIEW-GATE --- section-by-section human review (exit-11 pause).
  12. N-EMIT --- writes living-brief.md, brief-session.md, brief-crux-log.md.
  13. N-HANDOFF --- writes handoff.json for epiphany-spec.

Key properties

  • 17 nodes / 23 edges --- compact but expressive.
  • Gated fan-out --- explorer nodes dispatch in parallel.
  • Interview loop --- bounded HITL loop with one question per turn.
  • Coverage gate --- deterministic zero-loss verification.
