idea-spark — SPARK
Module: SPARK · Parent: 187web-ecosystem
Phase 1 foundation stub. Protocol: frame → diverge → critic → score → combine → converge → ADR.
Manual triggers
/187 spark, SPARK, brainstorm, idea-spark
When to use
Unresolved architecture or product options needing 3–5 distinct structures.
When not to use
Settled branding, logo, mascot geometry (forbidden to brainstorm rebrand).
Output contract
- Options (3–5)
- Criteria scores
- Selected option + rationale summary
- Rejected reasons
decision_record YAML fields
Safety
No brand reinterpretation. No illegal or unsafe “creative” paths.
Acceptance tests
- “Spark options for hub election” → ≥3 options + convergence.
- “Spark new logo colors” → refuse / redirect to brand lock.
