Implement State Hub v0.2: dependency graph, next-steps suggestions, design boundary S0 — Design boundary formalised across all integration surfaces: - TOOLS.md restructured with Design Boundary section, Sanctioned Write Tools, and Bootstrap-Only Tools (create_workstream, create_task) with explicit note - project_claude_md.template and railiance CLAUDE.md updated with boundary note and get_next_steps() in session start protocol - Global ~/.claude/CLAUDE.md updated accordingly S1 — Workstream dependency graph: - WorkstreamDependency model (directed edge, CASCADE on delete, unique pair constraint) - Alembic migration 0b547c153153; script.py.mako added (was missing) - REST API: POST/GET /workstreams/{id}/dependencies/, DELETE …/{dep_id} (hard delete) - StateSummary open_workstreams enriched with depends_on/blocks lists - MCP tools: create_dependency(), list_dependencies() - Dashboard workstreams page: Dependencies section with relationship cards - Seeded: custodian-agent-runtime → llm-shared-library + phase-0-operational-baseline S2 — Suggesting Next Steps (sanctioned write use case #2): - GET /state/next_steps derives suggestions from recently resolved decisions (→ first open task in same workstream) and cleared dependencies (→ first todo task in now-unblocked workstream) - StateSummary.next_steps included on every summary call - MCP tool: get_next_steps() - Dashboard: "What's next?" card grid above Registered Projects Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
