grounding-router（接地路由器）

Grounding Router

Version: 3.0.0 Architecture: atomic-permutation-router Trigger Keywords: grounding, saq, viva, textbook, pex, medical, citations, synthesis, sc:grounding

Progressive Loading:

• Level 0: Frontmatter (~100 tokens) - trigger detection only
• Level 1: Core SKILL.md (~2500 tokens) - primitives + routing
• Level 2: references/*.md - on-demand deep specifications
• Level 3: scripts/*.py - execute without loading context

Integrations:

• Skills: dialectical, critique, mega, textbook-grounding, saq, qp
• CLIs: limitless, research, pieces, pdf-search, pdf-brain, pex
• Commands: sc:grounding
• Routers: context-router

λΩ.τ: Query(ο) → Atomic-Composition(λ) → Grounded-Response(τ)

Routes grounding requests through minimal atomic primitives for maximal emergent function.

Trigger Conditions

Activate when:

• Explicit: /grounding, /saq, /viva, sc:grounding
• Implicit: SAQ, VIVA, medical exam, textbook citations, PEX sources
• Hook signal: need_grounding=true from intent detection

Mode Compositions

SAQ Mode: (Σ ⊗ Τ) ∘ Δ ∘ Ρₛ

Parallel source + textbook → Sequential synthesis → SAQ output
Word count: 180-220 | Citations: 5-10 | Tables: max 1

VIVA Mode: Σ* ∘ (Τ ⊗ Δ) ∘ Ρᵥ*

Recursive sources → Parallel ground+synthesize → Recursive expand
Word count: 500-800 | Citations: 15-25 | Examiner probes: 3-5

Academic Mode: Σ* ∘ Τ* ∘ Δ* ∘ Ρₐ

All recursive → Maximum depth → Full scholarly
Word count: 1000-2000 | Citations: 30-50 | Full bibliography

Confidence Calculation

confidence = (
    0.30 * source_authority +
    0.25 * textbook_coverage +
    0.20 * synthesis_parsimony +
    0.15 * citation_density +

Progressive Loading Protocol

Level 0: Trigger (Always Active)

• Frontmatter triggers in hook
• ~100 tokens loaded

Level 1: Core (On Trigger Match)

• This SKILL.md body
• Routing + primitive specs

Level 2: References (On Demand)

Load when confidence < 0.7 or customization needed:

• references/atomic-primitives.md — Full sub-primitive specs
• references/composition-patterns.md — Advanced compositions
• references/quality-gates.md — Detailed validation
• references/cli-integration.md — CLI command patterns

Level 3: Scripts (Execute Only)

Invoke without loading context:

• scripts/preflight.py --format json — CLI health
• scripts/extract.py "{query}" — Parallel extraction
• scripts/validate.py -r response.md — Hallucination check

Integration Points

Context Router Handoff

when: Σ primitives activated
action: Delegate to context-router for CLI orchestration
return: Aggregated sources to Τ primitive

Skill Integration

dialectical: Δ uses dialectical.atomic-composition
critique: G₄ uses critique.multi-lens
saq: Ρₛ uses saq.template
mega: Δ* escalates to mega when depth > 3

Command Integration

sc:grounding:
  invokes: grounding-router with mode detection
  flags: --mode, --sources, --specialty

Example Invocations

Basic SAQ

/grounding "Describe labetalol pharmacology" --mode=saq

Composition: (Σₗ ⊗ Σₜ ⊗ Σₐ) ∘ Δ ∘ Ρₛ
Output: 195-word SAQ with 7 citations
Confidence: 0.89

Extended VIVA

/grounding "Pre-eclampsia management" --mode=viva --sources=all

Composition: Σ* ∘ (Τ ⊗ Δ*) ∘ Ρᵥ*
Output: 650-word VIVA with 22 citations + 5 probes
Confidence: 0.92
